    To examine ways of ensuring access to health services within the framework of primary health care (PHC), since the goal of PHC to make universal health care available to all people has become increasingly neglected amid emerging themes of globalization, trade, and foreign policy. From a public health point of view, we argue that the premise of PHC can unlock barriers to health care services and contribute greatly to determining collective health through the promotion of universal basic health services. PHC has the most sophisticated and organized infrastructure, theories, and political principles, with which it can deal adequately with the issues of inequity, inequality, and social injustice which emerge from negative economic externalities and neo-liberal economic policies. Addressing these issues, especially the complex social and political influences that restrict access to medicines, may require the integration of different health initiatives into PHC. Based on current systems, PHC remains the only conventional health delivery service that can deal with resilient public health problems adequately. However, to strengthen its ability to do so, we propose the revitalization of PHC to incorporate scholarship that promotes human rights, partnerships, research and development, advocacy, and national drug policies. The concept of PHC can improve access; however, this will require the urgent interplay among theoretical, practical, political, and sociological influences arising from the economic, social, and political determinants of ill health in an era of globalization.

    2015-11-01

    The content of public health research is often statistically complex. This review seeks to assess the breadth of statistical literacy required to understand this material, with a view to informing practitioners' statistical training. We review the statistical content of original research articles published in 2011 in four major public health journals. Categories of statistical methodologies are identified and their frequency of use recorded. Methods' "usefulness" in terms of the extent to which their understanding increases accessibility to the literature is assessed. A total of 482 articles were reviewed and 30 categories of methods identified. Along with descriptive statistics (467 articles), regression analyses were also common, with logistic regression (206 articles) more than twice as prevalent as linear regression (95 articles). More complex regression models for use with clustered data were also commonly encountered, appearing in 96 articles. The public health literature features a wide variety of statistical methods, some of which are advanced. To ensure the literature remains accessible, training for public health practitioners should include statistical training that maximizes breadth as well as depth of understanding. © 2015 the Nordic Societies of Public Health.

    Full Text Available Abstract The author argues that measuring mortality in conflict settings is fraught with limitations which mostly result in under-estimation of mortality. Some recent publications on this subject have been based upon convenient surveillance processes, or even press reports. The author calls for vigilance against such studies and argues that war related surveillance-based mortality estimates should include measures of sensitivity and representativeness.

    Health statistics is an essential element to improve the ability of managers of health institutions, healthcare researchers, policy makers, and health professionals to formulate appropriate course of reactions and to make decisions based on evidence. To ensure adequate health statistics, standards are of critical importance. A study on healthcare statistics domain analysis is underway in an effort to improve usability and comparability of health statistics. The ongoing study focuses on structuring the domain knowledge and making the knowledge explicit with a data element dictionary being the core. Supplemental to the dictionary are a domain term list, a terminology dictionary, and a data model to help organize the concepts constituting the health statistics domain.

    2018-01-01

    Introduction: Human health directly depends on safety and quality of food. In turn, quality and safety of food directly depend on its production conditions and methods. There are two main food production methods: traditional and organic. Organic food production is considered safer and more beneficial for human health. Aim: to determine whether the organic food production method affects human health. Materials and methods: international acts, data of international organizations and conclusions of scientists have been examined and used in the study. The article also summarizes information from scientific journals and monographs from a medical and legal point of view with scientific methods. This article is based on dialectical, comparative, analytic, synthetic and comprehensive research methods. The problems of effects of food production methods and conditions on human health have been analyzed within the framework of the system approach. Conclusions: Food production methods and conditions ultimately affect the state and level of human health. The organic method of production activity has a positive effect on human health.

    Quality and ethics need to be embedded into all areas of research with human participants. Good Clinical Practice (GCP) guidelines are international ethical and scientific quality standards for designing, conducting, recording and reporting trials involving human participants. Compliance with GCP is expected to provide public assurance that the rights, safety and wellbeing of participants are protected and that the clinical research data are credible. However, whilst GCP guidelines, particularly their principles, are recommended across all research types, it is difficult for non-clinical trial research to fit in with the exacting requirements of GCP. There is therefore a need for guidance that allows health researchers to adhere to the principles of GCP, which will improve the quality and ethical conduct of all research involving human participants. These concerns have led to the development of the Good Health Research Practice (GHRP) course. Its goal is to ensure that research is conducted to the highest possible standards, similar to the conduct of trials to GCP. The GHRP course provides training and guidance to ensure quality and ethical conduct across all health-related research. The GHRP course has been run so far on eight occasions. Feedback from delegates has been overwhelmingly positive, with most delegates stating that the course was useful in developing their research protocols and documents. Whilst most training in research starts with a guideline, GHRP has started with a course and the experience gained over running the courses will be used to write a standardised guideline for the conduct of health-related research outside the realm of clinical trials, so that researchers, funders and ethics committees do not try to fit non-trials into clinical trials standards.

    The purpose of this program is to assess the methodology and available data sources appropriate for use in analytical studies and environmental impact statements concerning the health effects of nuclear power plants. The techniques developed should be applicable as well to evaluation of the known risks of high levels of radiation exposure and of conflicting evidence on low-level effects, such as those associated with the normal operations of nuclear power plants. To accomplish this purpose, a two-pronged approach has been developed. The first involves a determination of the public health and demographic data sources of local, state, and federal origin that are available for use in analyses of health effects and environmental impact statements. The second part involves assessment of the methods used by epidemiologists, biostatisticians, and other scientists as found in the literature on health effects. This two-pronged approach provides a means of assessing the strength and shortcomings of studies of the impact of nuclear facilities on the health of the general population in a given locality

    1997-01-01

    The Chronic Illness Management Research and Development Project (CIMRDP) was created as part of an effort to implement clinical process improvements in HealthSystems Minnesota, a vertically integrated care system in Minneapolis. CIMRDP's objective is to introduce sustainable improvements in the management of chronic illness. These types of quality improvement efforts require fundamental change at the organizational level, which often does not occur, and the programs do not continue beyond the initial stage. Using CIMRDP as a model for a sustainable chronic illness management program, this paper explores the process of implementing clinical guidelines for the management of chronic illness and contending with the complex problem of initiating change at an organizational level. It reviews factors critical to the success of such a program, including the use of focus groups to ensure a patient-centered approach, the advantage of hiring an outside consultant, the question of whether to accept external funding, and an evaluation outline of the six main tasks the program requires. Methods for marketing and integration are also presented.

    Nurses and midwives constitute the majority of the global health workforce and the largest health care expenditure. Efficient production, successful deployment, and ongoing retention based on carefully constructed policies regarding the career opportunities of nurses, midwives, and other providers in health care systems are key to ensuring universal health coverage. Yet nurses are constrained by practice regulations, workplaces, and career ladder barriers from contributing to primary health care delivery. Evidence shows that quality HIV care, comparable to that of physicians, is provided by trained nurses and associate clinicians, but many African countries' health systems remain dependent on limited numbers of physicians and fail to meet the demand for treatment. The World Health Organization endorses task sharing to ensure universal health coverage in HIV and maternal health, which requires an investment in nursing education, retention, and professional growth opportunities. Exemplars from Haiti, Rwanda, Republic of Georgia, and multi-country efforts are described. Copyright © 2016 Association of Nurses in AIDS Care. Published by Elsevier Inc. All rights reserved.

    2015-01-01

    Full Text Available Worldwide, the incidence of suicide has increased at an alarming rate and in the year 2012 close to 1 million people died because of suicide. Although, it is a well-acknowledged fact that suicides are completely preventable, the public health authorities have failed to halt the rising trend of the suicide because of the presence of various social and health related factors. As suicide is a complex issue, in the low and middle-income nations, the most cost-effective approach is to ensure the integration of suicide prevention program into the primary health care network. To conclude, suicide is an important public health concern which is definitively preventable. However, the need of the hour is that all the stakeholders should take collective responsibility, and work in collaboration to develop and implement a comprehensive multi-sectoral suicide prevention strategy.

    Full Text Available The sensitivity of health-care information and its accessibility via the Internet and mobile technology systems is a cause for concern in these modern times. The privacy, integrity and confidentiality of a patient’s data are key factors to be considered in the transmission of medical information for use by authorised health-care personnel. Mobile communication has enabled medical consultancy, treatment, drug administration and the provision of laboratory results to take place outside the hospital. With the implementation of electronic patient records and the Internet and Intranets, medical information sharing amongst relevant health-care providers was made possible. But the vital issue in this method of information sharing is security: the patient’s privacy, as well as the confidentiality and integrity of the health-care information system, should not be compromised. We examine various ways of ensuring the security and privacy of a patient’s electronic medical information in order to ensure the integrity and confidentiality of the information.

  2. Ensuring economic, health, and social well-being for Papua New Guinea through trade.

    2011-01-01

    The impacts of trade liberalization and open markets on global, regional, and local economies are a key consideration for those involved in government, business, and financial sectors. However, their impacts on health and social well-being of populations are not well-evidenced acknowledged within the health sector, let alone the impact on developing countries. As free trade becomes an inevitable outcome for many developing nations, the full implications of trade on economies, environments, and population health needs to be better articulated in order to ensure fully informed trade negotiations that support equitable outcomes. This article takes a broad look at the key issues for Papua New Guinea (PNG) in trade and how these translate to discrepancies in economic, health, and social benefits for its population. Despite its active trading and high GDP, only 10% of the population experience better economic and social outcomes. The bulk of PNG's population lives in poverty, challenged by geographical, cultural, and political barriers to better income, education, and health. Progress needs to be made to minimize these barriers and to allow more of PNG's population to experience the economic benefits generated through trade activities. A balance needs to be maintained between the desire of developed countries to broaden their markets, and the efforts of developing countries to promote and protect the health and well-being of their populations through increasing participation in global markets. PACER Plus presents an opportunity for pursuing alternative models of trade agreements that support and develop Pacific health.

    All the authors are agreed on the need for a certain publicizing of health statistics, but do Amaral Pyrrait points out that the medical profession prefers to convince itself rather than to be convinced. While there is great utility in articles and reviews in the professional press (especially for paramedical personnel) Aubenque, de Groot, and Kohn show how appreciation can effectively be secured by making statistics more easily understandable to the non-expert by, for instance, including readable commentaries in official publications, simplifying charts and tables, and preparing simple manuals on statistical methods. Aubenque and Kohn also stress the importance of linking health statistics to other economic and social information. Benjamin suggests that the principles of market research could to advantage be applied to health statistics to determine the precise needs of the "consumers". At the same time, Aubenque points out that the value of the ultimate results must be clear to those who provide the data; for this, Kohn suggests that the enumerators must know exactly what is wanted and why.There is general agreement that some explanation of statistical methods and their uses should be given in the curricula of medical schools and that lectures and postgraduate courses should be arranged for practising physicians.

    2009-06-01

    E-health implementation in Australia will depend upon interoperable computer systems to share information and data across the health sector. Semantic interoperability, which preserves the meaning of information and data when it is shared or re-purposed, is critical for safe clinical care, and also for any re-use of the information or data for other purposes. One such re-use is for national health statistics. Usable statistics rely on comparable and consistent data, and current practice is to use agreed national data standards to achieve this. The standardisation and interoperability needed to support e-health should also provide strong support for national health statistics. This report discusses some of the semantic interoperability issues involved in moving from the current data supply process for national health statistics to an e-health-enabled future.

    2016-08-01

    Full Text Available Sustainability relies on the environmental, social and economical systems: the three pillars of sustainability. The social sustainability mostly advocates the people’s welfare, health, safety, and quality of life. In the agricultural food industry, the aspects of social sustainability, such as consumer health and safety have gained substantial attention due to the frequent cases of food-borne diseases. The food-borne diseases due to the food degradation, chemical contamination and adulteration of food products pose a serious threat to the consumer’s health, safety, and quality of life. To ensure the consumer’s health and safety, it is essential to develop an efficient system which can address these critical social issues in the food distribution networks. This research proposes an ePedigree (electronic pedigree traceability system based on the integration of RFID and sensor technology for real-time monitoring of the agricultural food to prevent the distribution of hazardous and adulterated food products. The different aspects regarding implementation of the proposed system in food chains are analyzed and a feasible integrated solution is proposed. The performance of the proposed system is evaluated and finally, a comprehensive analysis of the proposed ePedigree system’s impact on the social sustainability in terms of consumer health and safety is presented.

    Nursing is a growing area of higher education, in which an introduction to statistics is an essential component. There is currently a gap in the market for a 'user-friendly' book which is contextulised and targeted for nursing. Practical Statistics for Nursing and Health Care introduces statistical techniques in such a way that readers will easily grasp the fundamentals to enable them to gain the confidence and understanding to perform their own analysis. It also provides sufficient advice in areas such as clinical trials and epidemiology to enable the reader to critically appraise work published in journals such as the Lancet and British Medical Journal. * Covers all basic statistical concepts and tests * Is user-friendly - avoids excessive jargon * Includes relevant examples for nurses, including case studies and data sets * Provides information on further reading * Starts from first principles and progresses step by step * Includes 'advice on' sections for all of the tests described.

  7. Steps to Ensure a Successful Implementation of Occupational Health and Safety Interventions at an Organizational Level

    Herrera-Sánchez, Isabel M.; León-Pérez, José M.; León-Rubio, José M.

    2017-01-01

    There is increasing meta-analytic evidence that addresses the positive impact of evidence-based occupational health and safety interventions on employee health and well-being. However, such evidence is less clear when interventions are approached at an organizational level and are aimed at changing organizational policies and processes. Given that occupational health and safety interventions are usually tailored to specific organizational contexts, generalizing and transferring such interventions to other organizations is a complex endeavor. In response, several authors have argued that an evaluation of the implementation process is crucial for assessing the intervention’s effectiveness and for understanding how and why the intervention has been (un)successful. Thus, this paper focuses on the implementation process and attempts to move this field forward by identifying the main factors that contribute toward ensuring a greater success of occupational health and safety interventions conducted at the organizational level. In doing so, we propose some steps that can guide a successful implementation. These implementation steps are illustrated using examples of evidence-based best practices reported in the literature that have described and systematically evaluated the implementation process behind their interventions during the last decade.

    Imperato, Pascal James; Bruno, Denise M; Monica Sweeney, M

    2016-04-01

    Global health electives based in resource-poor countries have become extremely popular with medical students from resource rich ones. As the number of such programs and participants increase, so too do the absolute health and safety risks. It is clear from a number of published reports that many institutions provide little or no meaningful preparedness for students and do little to ensure their health and safety. These deficiencies together can affect students, their foreign hosts, and sponsoring institutions. The School of Public Health at the State University of New York, Downstate Medical Center, and its predecessor, the Department of Preventive Medicine and Community Health, have sponsored a 6-8 week global health elective for fourth year medical students since 1980. The purposes of this elective are to provide students with an opportunity to observe the health care and public health systems in resource-poor countries, provide medical service, and have a cross-cultural experience. Over the course of the past 35 years, 386 students have participated in this global health elective in more than 41 resource-poor countries. Recent annual applications for this elective have been as high as 44 out of a class of 200 students. Over the past 10 years, annual acceptance rates have varied, ranging from a low of 32 % in 2007-2008 to a high of 74 % in 2010-2011 and 2013-2014. Careful screening, including a written application, review of academic records and personal interviews, has resulted in the selection of highly mature, adaptable, and dedicated students who have performed well at overseas sites. Appropriately preparing students for an overseas global health experience in resource-poor countries requires the investment of much professional and staff time and effort. At the SUNY Downstate School of Public Health, these resources have underpinned our Global Health in Developing Countries elective for many years. As a result, the elective is characterized by meticulous

    Full Text Available Todd M Sabato, Tanis J Walch, Dennis J Caine Department of Kinesiology and Public Health Education, University of North Dakota, Grand Forks, ND, USA Abstract: This article presents a current review of the risk of physical and psychological injury associated with participation in elite youth sport, and suggests strategies to ensure the physical and emotional health of these young athletes. Although there is lack of epidemiological data, especially with regard to psychological injury, preliminary data suggest that the risk of injury is high in this population. While there is lack of incident and follow-up data, there is also concern regarding burnout, disordered eating, and the long-term consequences of injury. Modifiable injury risk factors identified include postural control, competition anxiety, life events, previous injury, and volume of training. There are presently no studies designed to determine the effectiveness of injury prevention measures in elite youth sports. However, there is adequate evidence arising from injury prevention studies of youth sports participants – including neuromuscular training, protective equipment, mental training to enhance self-esteem, and sport rules modification – to prevent injuries in elite youth sports settings. Although not tested, psychosocial prevention strategies such as adoption of task-oriented coping mechanisms, autonomous support from parents, and a proactive organizational approach also show promise in injury prevention.

    This article presents a current review of the risk of physical and psychological injury associated with participation in elite youth sport, and suggests strategies to ensure the physical and emotional health of these young athletes. Although there is lack of epidemiological data, especially with regard to psychological injury, preliminary data suggest that the risk of injury is high in this population. While there is lack of incident and follow-up data, there is also concern regarding burnout, disordered eating, and the long-term consequences of injury. Modifiable injury risk factors identified include postural control, competition anxiety, life events, previous injury, and volume of training. There are presently no studies designed to determine the effectiveness of injury prevention measures in elite youth sports. However, there is adequate evidence arising from injury prevention studies of youth sports participants - including neuromuscular training, protective equipment, mental training to enhance self-esteem, and sport rules modification - to prevent injuries in elite youth sports settings. Although not tested, psychosocial prevention strategies such as adoption of task-oriented coping mechanisms, autonomous support from parents, and a proactive organizational approach also show promise in injury prevention.

    Full Text Available A community refers to a group of people who share the same stakes and concerns, the members of which knows and interact with each other. The process of diagnosing the health, health-related problems and their determinants, in a community is called community diagnosis, whose ultimate aim is to identify where the community is now?, where does it want to be?, and how it will get there? The principles of community diagnosis have been tried and found of extreme utility in developing countries where multiple health problems are prevalent, but only scarce resources are available. To conclude, the process of community diagnosis enables developing countries in reaching a consensus about the priority health problems in their individual communities and in developing strategies to address the identified issues.

    To emphasise the oral health needs of older individuals with intellectual and developmental disabilities, the impact on the individual's general health and the role that can be played by nurses. All too often an examination and consideration of the oral health condition of this patient population by nurses/physicians is cursory at best. The increasing retention of the dentition into later years of life provides both the favourable abilities for eating, speech and self esteem, but also the potential for local and general health concerns. Discursive paper. Based on the findings from dental examination of thousands of international athletes in the Special Olympic Games and clinical experiences in academic and private practice settings for care of individuals with intellectual and developmental disabilities, a discursive listing was developed for use in a preliminary examination of the oral cavity. A nurse can play a critical role in the examination, preventive services and referrals for dental care for older individuals with intellectual and developmental disabilities. The specific oral health needs of older individuals with intellectual and developmental disabilities should be an integral component of the preventive and general health care provided by nurses. © 2012 Blackwell Publishing Ltd.

    Full Text Available Congenital anomalies can be defined as structural or functional anomalies, including metabolic / biochemical disorders, which are present at the time of birth. Congenital anomalies has been recognized as a major public health concern, owing to its universal distribution, associated long-term disability; social stigma; emotional / psychological stress for the family members; increased medical expenditure; and burden on the health care delivery system and societies. To prevent the occurrence of congenital anomalies, due attention should be given to establishment of appropriate surveillance systems to record cases from both community and hospital settings; strengthening of public health system; promoting research to explore the etiological factors and diagnosis/prevention strategies; fostering international cooperation; and discouraging the practice of consanguineous marriage / conception at an advanced age / further reproduction after birth of a malformed child. To conclude, there is an indispensable need to formulate a comprehensive policy, that should be well-supported by an efficient surveillance system, dedicated health care professionals and involvement of all stakeholders.

    Sharpe, Virginia Ashby; Uchendu, Uchenna S

    2014-09-01

    Within health care systems, negative perceptions of lesbian, gay, bisexual, and transgender persons have often translated into denial of services, denial of visitation rights to same-sex partners, reluctance on the part of LGBT patients to share personal information, and failure of workers to assess and recognize the unique health care needs of these patients. Other bureaucratic forms of exclusion have included documents, forms, and policies that fail to acknowledge a patient's valued relationships because of, for example, a narrow definition of "spouse," "parent," or "family." Bureaucratic exclusion has taken a particularly prominent form in the U.S. military. Until its repeal and termination in 2011, the "Don't Ask, Don't Tell" policy had for eighteen years barred openly gay men and lesbians from serving in the military. Among the effects of DADT is a dearth of information about the number and needs of LGBT service members who transition to the Veterans Health Administration for health care at the end of their military service. The long-standing social stigma against LGBT persons, the silence mandated by DADT, and the often unrecognized bias built into the fabric of bureaucratic systems make the task of creating a welcoming culture in the VHA urgent and challenging. The VHA has accepted a commitment to that task. Its Strategic Plan for fiscal years 2013 through 2018 stipulates that "[v]eterans will receive timely, high quality, personalized, safe, effective and equitable health care irrespective of geography, gender, race, age, culture or sexual orientation." To achieve this goal, the VHA undertook a number of coordinated initiatives to create an environment and culture that is informed, welcoming, positive, and empowering for the LGBT veterans and families whom the agency serves. © 2014 by The Hastings Center.

    Full Text Available Public health datasets increasingly use geographic identifiers such as an individual’s address. Geocoding these addresses often provides new insights since it becomes possible to examine spatial patterns and associations. Address information is typically considered confidential and is therefore not released or shared with others. Publishing maps with the locations of individuals, however, may also breach confidentiality since addresses and associated identities can be discovered through reverse geocoding. One commonly used technique to protect confidentiality when releasing individual-level geocoded data is geographic masking. This typically consists of applying a certain amount of random perturbation in a systematic manner to reduce the risk of reidentification. A number of geographic masking techniques have been developed as well as methods to quantity the risk of reidentification associated with a particular masking method. This paper presents a review of the current state-of-the-art in geographic masking, summarizing the various methods and their strengths and weaknesses. Despite recent progress, no universally accepted or endorsed geographic masking technique has emerged. Researchers on the other hand are publishing maps using geographic masking of confidential locations. Any researcher publishing such maps is advised to become familiar with the different masking techniques available and their associated reidentification risks.

    Soil health as a factor of ensuring food security (the case of the Asia-Pacific Region) Food security is a complex issue of both international and national levels. The food embargo on imported products has defined the preservation and regeneration of soils as a priority task in ensuring the food security of the Russian Federation. Soils are a finite, non-renewable resource and their preservation is extremely important for the national food security. Food production is the major function of soils; production of high-quality foods, rich in nutrients, is possible only in healthy soils. Therefore, a healthy and fertile soil is the most important factor in ensuring the food security and improved subsistence. By 2050, in order to meet the demand for food, the global agricultural production has to increase by 60%, and almost by 100% in the developing countries. In many countries and subregions of the Asia-Pacific Region, the population growth rates outrun the rates of food production. The possibilities of incorporating new lands into agricultural activities and providing their irrigation are also limited. In the context of expanding cooperation with the Asia-Pacific neighbors, Russia can make its contribution into improving the food security of the region. Russia has vast territories that could be used for crops farming; a substantial part of these lands have not been farmed yet. Hence, in the Russian Far East, production of grain crops can be increased by incorporating the unused territories into agricultural activities. Therefore, the Russian Far East is a unique site for creating a crops farming territory. And the preservation and regeneration of soils will provide for the production growth and ensure the food security of Russia and the Asia-Pacific region.

  14. Ensuring equity of access to primary health care in rural and remote Australia - what core services should be locally available?

    Thomas, Susan L; Wakerman, John; Humphreys, John S

    2015-10-29

    Australians in rural and remote areas experience poorer health status compared with many metropolitan residents, due partly to inequitable access to primary health care (PHC) services. Building on recent research that identified PHC services which all Australians should be able to access regardless of where they live, this paper aims to define the population thresholds governing which PHC services would be best provided by a resident health worker, and to outline attendant implementation issues. A Delphi method comprising panellists with expertise in rural, remote and/or Indigenous PHC was used. Five population thresholds reflecting Australia's diverse rural and remote geography were devised. Panellists participated in two electronic surveys. Using a Likert scale, they were asked at what population threshold each PHC service should be provided by a resident health worker. A follow-up focus group identified important underlying principles which guided the consensus process. Response rates were high. The population thresholds for core PHC services provided by a resident worker were less in remote communities compared with rural communities. For example, the population threshold for 'care of the sick and injured,' was ≤100 for remote compared with 101-500 for rural communities. For 'mental health', 'maternal/child health', 'sexual health' and 'public health' services in remote communities the population threshold was 101-500, compared to 501-1000 for rural communities. Principles underpinning implementation included the fundamental importance of equity; consideration of social determinants of health; flexibility, effective expenditure of resources, tailoring services to ensure consumer acceptability, prioritising services according to need, and providing services as close to home as possible. This research can assist policy makers and service planners to determine the population thresholds at which PHC services should be delivered by a resident health worker, to

    Arendt Maryse

    2008-06-01

    Full Text Available Abstract This article addresses the problem of how to ensure consistency in messages communicating public health recommendations on environmental health and on child health. The World Health Organization states that the protection, promotion and support of breastfeeding rank among the most effective interventions to improve child survival. International public health policy recommends exclusive breastfeeding for six months, followed by continued breastfeeding with the addition of safe and adequate complementary foods for two years and beyond. Biomonitoring of breastmilk is used as an indicator of environmental pollution ending up in mankind. This article will therefore present the biomonitoring results of concentrations of residues in breastmilk in a wider context. These results are the mirror that reflects the chemical substances accumulated in the bodies of both men and women in the course of a lifetime. The accumulated substances in our bodies may have an effect on male or female reproductive cells; they are present in the womb, directly affecting the environment of the fragile developing foetus; they are also present in breastmilk. Evidence of man-made chemical residues in breastmilk can provide a shock tactic to push for stronger laws to protect the environment. However, messages about chemicals detected in breastmilk can become dramatized by the media and cause a backlash against breastfeeding, thus contradicting the public health messages issued by the World Health Organization. Analyses of breastmilk show the presence of important nutritional components and live protective factors active in building up the immune system, in gastro intestinal maturation, in immune defence and in providing antiviral, antiparasitic and antibacterial activity. Through cohort studies researchers in environmental health have concluded that long-term breastfeeding counterbalances the effect of prenatal exposure to chemicals causing delay in mental and

    Haslegrave, Marianne

    2013-11-01

    Since the 1994 International Conference on Population and Development (ICPD) in Cairo placed reproductive health and rights firmly on the international agenda, civil society and other advocates have worked ceaselessly to ensure that they remain central to women's empowerment and have taken all opportunities to expand the framework to include sexual health and rights. When the development process changed with the introduction of the Millennium Development Goals (MDGs) in 2000, sexual and reproductive health and rights were excluded, and only in 2007 was universal access to reproductive health added back in. In 2014 and 2015, the future of ICPD Beyond 2014, the MDGs and the post-2015 development framework will be decided, following consultations and meetings across the globe. This paper takes stock of the key influences on efforts to achieve the ICPD agenda and summarises the past, current and planned future events, reports and processes between 1994 and 2014, leading up to the determination of the post-2015 development framework and sustainable development goals. It concludes that the one thing we cannot afford to allow is what happened with the MDGs in 2000. We must not leave the room empty-handed, but must instead ensure the inclusion of sexual and reproductive health and rights as a priority under a new health goal.

    Integrated into the work in health systems strengthening (HSS) is a growing focus on the importance of ensuring quality of the services delivered and systems which support them. Understanding how to define and measure quality in the different key World Health Organization building blocks is critical to providing the information needed to address gaps and identify models for replication. We describe the approaches to defining and improving quality across the five country programs funded through the Doris Duke Charitable Foundation African Health Initiative. While each program has independently developed and implemented country-specific approaches to strengthening health systems, they all included quality of services and systems as a core principle. We describe the differences and similarities across the programs in defining and improving quality as an embedded process essential for HSS to achieve the goal of improved population health. The programs measured quality across most or all of the six WHO building blocks, with specific areas of overlap in improving quality falling into four main categories: 1) defining and measuring quality; 2) ensuring data quality, and building capacity for data use for decision making and response to quality measurements; 3) strengthened supportive supervision and/or mentoring; and 4) operational research to understand the factors associated with observed variation in quality. Learning the value and challenges of these approaches to measuring and improving quality across the key components of HSS as the projects continue their work will help inform similar efforts both now and in the future to ensure quality across the critical components of a health system and the impact on population health.

    Issues related to lack of system usability and potential safety hazards continue to be reported in the health information technology (HIT) literature. Usability engineering methods are increasingly used to ensure improved system usability and they are also beginning to be applied more widely for ensuring the safety of HIT applications. These methods are being used in the design and implementation of many HIT systems. In this paper we describe evidence-based approaches to applying usability engineering methods. A multi-phased approach to ensuring system usability and safety in healthcare is described. Usability inspection methods are first described including the development of evidence-based safety heuristics for HIT. Laboratory-based usability testing is then conducted under artificial conditions to test if a system has any base level usability problems that need to be corrected. Usability problems that are detected are corrected and then a new phase is initiated where the system is tested under more realistic conditions using clinical simulations. This phase may involve testing the system with simulated patients. Finally, an additional phase may be conducted, involving a naturalistic study of system use under real-world clinical conditions. The methods described have been employed in the analysis of the usability and safety of a wide range of HIT applications, including electronic health record systems, decision support systems and consumer health applications. It has been found that at least usability inspection and usability testing should be applied prior to the widespread release of HIT. However, wherever possible, additional layers of testing involving clinical simulations and a naturalistic evaluation will likely detect usability and safety issues that may not otherwise be detected prior to widespread system release. The framework presented in the paper can be applied in order to develop more usable and safer HIT, based on multiple layers of evidence.

    To communicate population-based cancer statistics, cancer researchers have a long tradition of presenting data in a spatial representation, or map. Historically, health data were presented in printed atlases in which the map producer selected the content and format. The availability of geographic information systems (GIS) with comprehensive mapping and spatial analysis capability for desktop and Internet mapping has greatly expanded the number of producers and consumers of health maps, including policymakers and the public.Because health maps, particularly ones that show elevated cancer rates, historically have raised public concerns, it is essential that these maps be designed to be accurate, clear, and interpretable for the broad range of users who may view them. This article focuses on designing maps to communicate effectively. It is based on years of research into the use of health maps for communicating among public health researchers. The basics for designing maps that communicate effectively are similar to the basics for any mode of communication. Tasks include deciding on the purpose, knowing the audience and its characteristics, choosing a media suitable for both the purpose and the audience, and finally testing the map design to ensure that it suits the purpose with the intended audience, and communicates accurately and effectively. Special considerations for health maps include ensuring confidentiality and reflecting the uncertainty of small area statistics. Statistical maps need to be based on sound practices and principles developed by the statistical and cartographic communities. The biggest challenge is to ensure that maps of health statistics inform without misinforming. Advances in the sciences of cartography, statistics, and visualization of spatial data are constantly expanding the toolkit available to mapmakers to meet this challenge.

    CERN Document Server

    Wu, Pan; Chen, Ding-Geng

    2016-01-01

    This book compiles and presents new developments in statistical causal inference. The accompanying data and computer programs are publicly available so readers may replicate the model development and data analysis presented in each chapter. In this way, methodology is taught so that readers may implement it directly. The book brings together experts engaged in causal inference research to present and discuss recent issues in causal inference methodological development. This is also a timely look at causal inference applied to scenarios that range from clinical trials to mediation and public health research more broadly. In an academic setting, this book will serve as a reference and guide to a course in causal inference at the graduate level (Master's or Doctorate). It is particularly relevant for students pursuing degrees in Statistics, Biostatistics and Computational Biology. Researchers and data analysts in public health and biomedical research will also find this book to be an important reference.

    The aim of the current article is to provide a brief introduction to Bayesian statistics within the field of health psychology. Bayesian methods are increasing in prevalence in applied fields, and they have been shown in simulation research to improve the estimation accuracy of structural equation models, latent growth curve (and mixture) models, and hierarchical linear models. Likewise, Bayesian methods can be used with small sample sizes since they do not rely on large sample theory. In this article, we discuss several important components of Bayesian statistics as they relate to health-based inquiries. We discuss the incorporation and impact of prior knowledge into the estimation process and the different components of the analysis that should be reported in an article. We present an example implementing Bayesian estimation in the context of blood pressure changes after participants experienced an acute stressor. We conclude with final thoughts on the implementation of Bayesian statistics in health psychology, including suggestions for reviewing Bayesian manuscripts and grant proposals. We have also included an extensive amount of online supplementary material to complement the content presented here, including Bayesian examples using many different software programmes and an extensive sensitivity analysis examining the impact of priors.

    Accurate, understandable public health information is important for ensuring the health of the nation. The large portion of the US population with Limited English Proficiency is best served by translations of public-health information into other languages. However, a large number of health departments and primary care clinics face significant barriers to fulfilling federal mandates to provide multilingual materials to Limited English Proficiency individuals. This article presents a pilot study on the feasibility of using freely available statistical machine translation technology to translate health promotion materials. The authors gathered health-promotion materials in English from local and national public-health websites. Spanish versions were created by translating the documents using a freely available machine-translation website. Translations were rated for adequacy and fluency, analyzed for errors, manually corrected by a human posteditor, and compared with exclusively manual translations. Machine translation plus postediting took 15-53 min per document, compared to the reported days or even weeks for the standard translation process. A blind comparison of machine-assisted and human translations of six documents revealed overall equivalency between machine-translated and manually translated materials. The analysis of translation errors indicated that the most important errors were word-sense errors. The results indicate that machine translation plus postediting may be an effective method of producing multilingual health materials with equivalent quality but lower cost compared to manual translations.

    Many doctors, patients, journalists, and politicians alike do not understand what health statistics mean or draw wrong conclusions without noticing. Collective statistical illiteracy refers to the widespread inability to understand the meaning of numbers. For instance, many citizens are unaware that higher survival rates with cancer screening do not imply longer life, or that the statement that mammography screening reduces the risk of dying from breast cancer by 25% in fact means that 1 less woman out of 1,000 will die of the disease. We provide evidence that statistical illiteracy (a) is common to patients, journalists, and physicians; (b) is created by nontransparent framing of information that is sometimes an unintentional result of lack of understanding but can also be a result of intentional efforts to manipulate or persuade people; and (c) can have serious consequences for health. The causes of statistical illiteracy should not be attributed to cognitive biases alone, but to the emotional nature of the doctor-patient relationship and conflicts of interest in the healthcare system. The classic doctor-patient relation is based on (the physician's) paternalism and (the patient's) trust in authority, which make statistical literacy seem unnecessary; so does the traditional combination of determinism (physicians who seek causes, not chances) and the illusion of certainty (patients who seek certainty when there is none). We show that information pamphlets, Web sites, leaflets distributed to doctors by the pharmaceutical industry, and even medical journals often report evidence in nontransparent forms that suggest big benefits of featured interventions and small harms. Without understanding the numbers involved, the public is susceptible to political and commercial manipulation of their anxieties and hopes, which undermines the goals of informed consent and shared decision making. What can be done? We discuss the importance of teaching statistical thinking and

    A community health assessment (CHA) is used to identify and address health issues in a given population. Effective CHA requires timely and comprehensive information from a wide variety of sources, such as: socio-economic data, disease surveillance, healthcare utilization, environmental data, and health resource allocation. Indonesia is a developing country with 235 million inhabitants over 13,000 islands. There are significant barriers to conducting CHA in developing countries like Indonesia, such as the high cost of computing resources and the lack of computing skills necessary to support such an assessment. At the University of Pittsburgh, we have developed the Spatial OLAP (On-Line Analytical Processing) Visualization and Analysis Tool (SOVAT) for performing CHA. SOVAT combines Geographic Information System (GIS) technology along with an advanced multidimensional data warehouse structure to facilitate analysis of large, disparate health, environmental, population, and spatial data. The objective of this paper is to demonstrate the potential of SOVAT for facilitating CHA among developing countries by using health, population, healthcare resources, and spatial data from Indonesia for use in two CHA cases studies. Bureau of Statistics administered data sets from the Indonesian Census, and the Indonesian village statistics, were used in the case studies. The data consisted of: healthcare resources (number of healthcare professionals and facilities), population (census), morbidity and mortality, and spatial (GIS-formatted) information. The data was formatted, combined, and populated into SOVAT for CHA use. Case study 1 involves the distribution of healthcare professionals in Indonesia, while case study 2 involves malaria mortality. Screen shots are shown for both cases. The results for the CHA were retrieved in seconds and presented through the geospatial and numerical SOVAT interface. The case studies show the potential of spatial and multidimensional analysis using

    Research indicates that fear of immigration enforcement among Latinos in North Carolina results in limited access to and utilization of health services and negative health consequences. This project developed recommendations to mitigate the public health impact of immigration enforcement policies in North Carolina. Our community-based participatory research partnership conducted 6 Spanish-language report-backs (an approach to sharing, validating, and interpreting data) and 3 bilingual forums with community members and public health leaders throughout North Carolina. The goals of these events were to discuss the impact of immigration enforcement on Latino health and develop recommendations to increase health services access and utilization. Findings from the report-backs and forums were analyzed using grounded theory to identify and refine common recommendations. A total of 344 people participated in the report-backs and forums. Eight recommendations emerged: increase knowledge among Latinos about local health services; build capacity to promote policy changes; implement system-level changes among organizations providing health services; train lay health advisors to help community members navigate systems; share Latinos' experiences with policy makers; reduce transportation barriers; increase schools' support of Latino families; and increase collaboration among community members, organizations, health care providers, and academic researchers. Representatives from 16 of 100 North Carolina counties participated. These 16 counties represent geographically diverse regions, and many of these counties have large Latino populations. Immigration enforcement is a public health issue. Participants proposed developing new partnerships, identifying strategies, and implementing action steps for carrying out recommendations to reduce negative health outcomes among Latinos in North Carolina. ©2016 by the North Carolina Institute of Medicine and The Duke Endowment.

    Objective To examine the feasibility of using statistical text classification to automatically identify health information technology (HIT) incidents in the USA Food and Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database. Design We used a subset of 570 272 incidents including 1534 HIT incidents reported to MAUDE between 1 January 2008 and 1 July 2010. Text classifiers using regularized logistic regression were evaluated with both ‘balanced’ (50% HIT) and ‘stratified’ (0.297% HIT) datasets for training, validation, and testing. Dataset preparation, feature extraction, feature selection, cross-validation, classification, performance evaluation, and error analysis were performed iteratively to further improve the classifiers. Feature-selection techniques such as removing short words and stop words, stemming, lemmatization, and principal component analysis were examined. Measurements κ statistic, F1 score, precision and recall. Results Classification performance was similar on both the stratified (0.954 F1 score) and balanced (0.995 F1 score) datasets. Stemming was the most effective technique, reducing the feature set size to 79% while maintaining comparable performance. Training with balanced datasets improved recall (0.989) but reduced precision (0.165). Conclusions Statistical text classification appears to be a feasible method for identifying HIT reports within large databases of incidents. Automated identification should enable more HIT problems to be detected, analyzed, and addressed in a timely manner. Semi-supervised learning may be necessary when applying machine learning to big data analysis of patient safety incidents and requires further investigation. PMID:23666777

    Data warehouse implementation is assumed to be a very knowledge-demanding, expensive and long-lasting process. As such it requires senior management sponsorship, involvement of experts, a big budget and probably years of development time. Presented Outpatient Health Care Statistics Data Warehouse implementation research provides ample evidence against the infallibility of the above statements. New, inexpensive, but powerful technology, which provides outstanding platform for On-Line Analytical Processing (OLAP), has emerged recently. Presumably, it will be the basis for the estimated future growth of data warehouse market, both in the medical and in other business fields. Methods and tools for building, maintaining and exploiting data warehouses are also briefly discussed in the paper.

    Poor maintenance of school environment can cause or worsen illnesses among schoolchildren. The objective of this study was to assess the healthfulness of school environments of primary schools in Enugu East, Nigeria, and to compare the difference if any between public and private schools. This was a cross-sectional noninterventional study of the school environments in Enugu East, Nigeria. Multistage sampling method was used to select the sample population. The participating schools were inspected and their head teachers were interviewed using a questionnaire. Scores were awarded using the School Health Program Evaluation scale. Results: Thirty-three schools were studied. The most common source of water for most schools was well. Eleven schools dump refuse openly. Three public schools only had functional toilets. All public schools were adequately ventilated and lit. One private school had a foodservice area. Ten schools did not have a play field, while three public schools had soaps for handwashing. The mean scores for public and private schools were 33.00 and 37.86, respectively. Three schools only attained the minimum score of 57 of a maximum of 66. The environment of primary schools in Enugu east, Nigeria, is unhealthy and unfriendly and currently cannot promote and protect the health of the schoolchildren.

  16. Feature and Statistical Model Development in Structural Health Monitoring

    Science.gov (United States)

    Kim, Inho

    All structures suffer wear and tear because of impact, excessive load, fatigue, corrosion, etc. in addition to inherent defects during their manufacturing processes and their exposure to various environmental effects. These structural degradations are often imperceptible, but they can severely affect the structural performance of a component, thereby severely decreasing its service life. Although previous studies of Structural Health Monitoring (SHM) have revealed extensive prior knowledge on the parts of SHM processes, such as the operational evaluation, data processing, and feature extraction, few studies have been conducted from a systematical perspective, the statistical model development. The first part of this dissertation, the characteristics of inverse scattering problems, such as ill-posedness and nonlinearity, reviews ultrasonic guided wave-based structural health monitoring problems. The distinctive features and the selection of the domain analysis are investigated by analytically searching the conditions of the uniqueness solutions for ill-posedness and are validated experimentally. Based on the distinctive features, a novel wave packet tracing (WPT) method for damage localization and size quantification is presented. This method involves creating time-space representations of the guided Lamb waves (GLWs), collected at a series of locations, with a spatially dense distribution along paths at pre-selected angles with respect to the direction, normal to the direction of wave propagation. The fringe patterns due to wave dispersion, which depends on the phase velocity, are selected as the primary features that carry information, regarding the wave propagation and scattering. The following part of this dissertation presents a novel damage-localization framework, using a fully automated process. In order to construct the statistical model for autonomous damage localization deep-learning techniques, such as restricted Boltzmann machine and deep belief network

    There are different types of information on men's health in older age. High morbidity burden is offset by subjective assessments of "very good" and "good" health by 52% of men over 65 years. The aim of this study is to assess the health situation of seniors from official publications and public health reports. How can the quality of life in our male population be positively influenced so that they can actively participate in society in old age. Information on the health of seniors and burden of disease were taken from men's health reports and official publications from the Robert-Koch-Institute, the Federal Statistical Office, and the IHME Institute of the USA according to age groups and gender. Burden of disease in seniors is influenced by one's own health behavior and the social situation. The increase in life expectancy of seniors is characterized by longer life with chronic conditions. Official statistics indicate that about 50% of seniors are affected by disease or severe disability, while 50% assess their health status as "very good" or "good". Aging of the population requires diverse health promotion activities. Parallel with the inevitable increased multimorbidity in the elderly, maintaining and increase of physical fitness is required so that seniors have a positive "subjective health" or "wellbeing".

    2011-12-01

    Full Text Available This paper is devoted to the questions of further development of agricultural and food policy in the Russian Federation. The subject of in-depth consideration is the problem related to ensuring food safety. A critical review and analysis of major regulations in the field of food safety is made, including in the implementation of sanitary and epidemiological surveillance. The necessity of the expansion of measures to improve the statistics of food poisoning is grounded. The basic reasons for the spread of management practices of production and sale of food products that pose a threat to human life are revealed. The factors of unhindered penetration of local markets in the cities and the surrounding countrysides with counterfeiting, smuggling and production of global junk food manufacturers and consumer goods are defined. A systematic view is put on the problems of food production in the private farms, ways to limit direct access to the market of food and food raw materials, which production was not controlled and who have not passed state registration, are suggested. One of these problems is creation of independent industrial structures that link production and sales of small-scale sector goods.

  1. Global health business: the production and performativity of statistics in Sierra Leone and Germany.

    Science.gov (United States)

    Erikson, Susan L

    2012-01-01

    The global push for health statistics and electronic digital health information systems is about more than tracking health incidence and prevalence. It is also experienced on the ground as means to develop and maintain particular norms of health business, knowledge, and decision- and profit-making that are not innocent. Statistics make possible audit and accountability logics that undergird the management of health at a distance and that are increasingly necessary to the business of health. Health statistics are inextricable from their social milieus, yet as business artifacts they operate as if they are freely formed, objectively originated, and accurate. This article explicates health statistics as cultural forms and shows how they have been produced and performed in two very different countries: Sierra Leone and Germany. In both familiar and surprising ways, this article shows how statistics and their pursuit organize and discipline human behavior, constitute subject positions, and reify existing relations of power.

    2009-01-01

    The main purpose of this study is to develop and test a generic model for workplace health management in organizations. Four private and four public organizations in northern Sweden were selected for the study. A model for health control was developed on the basis of a literature review and dialogues with the stakeholders in the workplaces. The model was then implemented at the workplaces during a two-year period. Interviews with leaders and co-workers were conducted on two occasions and were analyzed using content analysis and the constant comparison method. By using a grounded theory approach, three main categories were found: health closure and other health and working environment indicators, monetary accounting of health related indicators and changes in leadership behaviour and organizational practices. An important result was that the model influenced leadership values more than leadership and organizational methodologies. From the results a model for workplace health management is proposed, incorporating the planning, control, and improvement structures. The purpose of the model is to take health aspects into consideration when deciding organizational structure (work demands, control and social support). The model controls health by using health-related indicators with high frequency measuring whereas workplace health promotion is done in a structured way with a reflective model.

    Green, R S; Speiglman, R

    1997-01-01

    Managers of long-term care organizations lack usable information about patterns of stay, because the time spent by residents typically exceeds the length of reporting and reimbursement periods. Formulas for estimating lengths of stay often yield unstable estimates of long-term stays. Consequently, little insight is gained into changes that may be occurring in stay patterns as the organization adapts its service processes to shifts in markets. An alternative length of stay statistic is proposed from which patterns of stay can be more clearly discerned. Examples utilizing both simulated and field data are presented to highlight the advantages associated with the new statistic.

    Hotspots indicate area that has a higher case intensity than others. For example, in health problems of an area, the number of sickness of a region can be used as parameter and condition of area that determined severity of an area. If this condition is known soon, it can be overcome preventively. Many factors affect the severity level of area. Some health factors to be considered in this study are the number of infant with low birth weight, malnourished children under five years old, under five years old mortality, maternal deaths, births without the help of health personnel, infants without handling the baby's health, and infant without basic immunization. The number of cases is based on every public health center area in Depok. Correspondence analysis provides graphical information about two nominal variables relationship. It create plot based on row and column scores and show categories that have strong relation in a close distance. Scan Statistic method is used to examine hotspot based on some selected variables that occurred in the study area; and Correspondence Analysis is used to picturing association between the regions and variables. Apparently, using SaTScan software, Sukatani health center is obtained as a point hotspot; and Correspondence Analysis method shows health centers and the seven variables have a very significant relationship and the majority of health centers close to all variables, except Cipayung which is distantly related to the number of pregnant mother death. These results can be used as input for the government agencies to upgrade the health level in the area.

  7. Differences in health care spending across countries: statistical evidence.

    Science.gov (United States)

    Pfaff, M

    1990-01-01

    The empirical evidence available for OECD countries suggests that economic factors play a major role and that demographic factors play a minor role in explaining differences in health care spending across countries. When countries are grouped on the basis of their health care systems, some significant cross-country differences result: countries with higher transfer rates (a larger share of collective financing) are not generally characterized by higher health care expenditures, and conversely, countries with a larger share of private financing (including higher coinsurance rates) do not have lower expenditures. Rather, the opposite holds true. Similar conclusions apply to the share of public versus private production of health goods. Furthermore, the results do not support the claims of those critics of universal public insurance systems who consider the expansion of the coverage to be a major source of expenditure growth. These findings cast serious doubt on the claim that cost containment can be achieved via market reforms that rely heavily on direct consumer payments and cost sharing as instruments of financing. A comparative analysis of the historic record of the United States, Canada, and the Federal Republic of Germany generally supports these conclusions; it also suggests that a greater degree of public penetration offers a better chance for control of health spending, particularly in periods of austerity. There is a strong presumption that health care systems relying on some overall control of spending generally are more cost-effective than those relying more on decentralized mechanisms of control. Services are more equitably distributed in relation to health and payment for health services is far more progressive in the former type of system.

    2017-04-01

    In two separate investigations, we examined the persuasive effectiveness of statistical versus exemplar appeals on Indian adults' smoking cessation and mammography screening intentions. To more comprehensively address persuasion processes, we explored whether message response and perceived message effectiveness functioned as antecedents to persuasive effects. Results showed that statistical appeals led to higher levels of health intentions than exemplar appeals. In addition, findings from both studies indicated that statistical appeals stimulated more attention and were perceived as more effective than anecdotal accounts. Among male smokers, statistical appeals also generated greater cognitive processing than exemplar appeals. Subsequent mediation analyses revealed that message response and perceived message effectiveness fully carried the influence of appeal format on health intentions. Given these findings, future public health initiatives conducted among similar populations should design messages that include substantive factual information while ensuring that this content is perceived as credible and valuable.

  9. "Ensure that you are well aware of the risks you are taking…": actions and activities medical tourists' informal caregivers can undertake to protect their health and safety.

    When seeking care at international hospitals and clinics, medical tourists are often accompanied by family members, friends, or other caregivers. Such caregiver-companions assume a variety of roles and responsibilities and typically offer physical assistance, provide emotional support, and aid in decision-making and record keeping as medical tourists navigate unfamiliar environments. While traveling abroad, medical tourists' caregiver-companions can find themselves confronted with challenging communication barriers, financial pressures, emotional strain, and unsafe environments. To better understand what actions and activities medical tourists' informal caregivers can undertake to protect their health and safety, 20 interviews were conducted with Canadians who had experienced accompanying a medical tourist to an international health care facility for surgery. Interview transcripts were subsequently used to identify inductive and deductive themes central to the advice research participants offered to prospective caregiver-companions. Advice offered to future caregiver-companions spanned the following actions and activities to protect health and safety: become an informed health care consumer; assess and avoid exposure to identifiable risks; anticipate the care needs of medical tourists and thereby attempt to guard against caregiver burden; become familiar with important logistics related to travel and anticipated recovery timelines; and take practical measures to protect one's own health. Given that a key feature of public health is to use research findings to develop interventions and policies intended to promote health and reduce risks to individuals and populations, the paper draws upon major points of advice offered by study participants to take the first steps toward the development of an informational intervention designed specifically for the health and safety needs of medical tourists' caregiver companions. While additional research is required to finalize

    Given that many households in western countries nowadays have home access to the Internet, developing health-promoting online interventions has the potential to reach large audiences. Studies assessing usage data of online health interventions are important and relevant but, as of yet, scarce. The present study reviewed usage data from Monkey Do, an existing online health game developed specifically for children from 4 to 8 years old. In addition, the effect of advertising on usage was examined. In an observational study, a web-based analysis program was used to examine usage data of all visits to the online health game for the first 31 months following the launch. We reported descriptives for usage data. We analyzed the relationship between advertising and usage with a Mann-Whitney U test, and used a Pearson's chi-square test to investigate the association between advertising and the number of first-time visitors. In the period of data analysis, there were 224,859 sessions. Around 34% of the visitors played the game more than once. Compared with first-time visitors, the average session time of returning visitors was doubled. The game was most frequently accessed via search engine query, on a desktop computer (compared to mobile devices). Advertising was found to be positively related to the number of sessions and the number of first-time visitors. Placing a game online can reach a large audience, but it is important to also consider how to stimulate retention. Furthermore, repeated advertisement for an online game appears to be necessary to maintain visitors over time.

    Srinivasa Rao, Putti; Ratnam, Ch.

    2012-02-01

    This paper presents health monitoring of welded structures using acceleration time response data. Residual errors are extracted from the measured acceleration time response data using an auto-regressive model. Damage identification is done by monitoring the residual errors using Shewhart and exponentially weighted moving average control charts. The applicability of the proposed method is tested with the welded structure model. Five damage levels are investigated and the damage is introduced by cutting a slot in the weld using an electrical discharge machine. Acceleration time response data are collected using piezoelectric sensors for all damage levels. The results show that both Shewhart and exponentially weighted moving average control charts are capable of identifying the presence of damage in the welded structure model under consideration. Exponentially weighted moving average control charts are more sensitive in damage identification than Shewhart control charts.

    We show that the modular transformations for one point functions on the torus, S(n), satisfy the polynomial equations derived by Moore and Seiberg, provided the duality property of the model is ensured. The formula for S(n) is derived by us previously and should be valid for any conformal field theory. As a consequence, the full consistency conditions for modular invariance at higher genus are completely guaranteed by duality of the theory on the sphere. (orig.)

    The Japanese government at present is implementing international health and medical growth strategies mainly from the viewpoint of business. However, the United Nations is set to resolve the Post-2015 Development Agenda in the fall of 2015; the agenda will likely include the achievement of universal health coverage (UHC) as a specific development goal. Japan's healthcare system, the foundation of which is its public, nationwide universal health insurance program, has been evaluated highly by the Lancet. The World Bank also praised it as a global model. This paper presents suggestions and problems for Japan regarding global health strategies, including in regard to several prerequisite domestic preparations that must be made. They are summarized as follows. (1) The UHC development should be promoted in coordination with the United Nations, World Bank, and Asian Development Bank. (2) The universal health insurance system of Japan can be a global model for UHC and ensuring its sustainability should be considered a national policy. (3) Trade agreements such as the Trans-Pacific Partnership (TPP) should not disrupt or interfere with UHC, the form of which is unique to each nation, including Japan. (4) Japan should disseminate information overseas, including to national governments, people, and physicians, regarding the course of events that led to the establishment of the Japan's universal health insurance system and should make efforts to develop international human resources to participate in UHC policymaking. (5) The development of separate healthcare programs and UHC preparation should be promoted by streamlining and centralizing maternity care, school health, infectious disease management such as for tuberculosis, and emergency medicine such as for traffic accidents. (6) Japan should disseminate information overseas about its primary care physicians (kakaritsuke physicians) and develop international human resources. (7) Global health should be developed in

    The health status of the American slave in the 19th century remains unclear despite extensive historical research. Better knowledge of slave health would provide a clearer picture of the life of the slave, a better understanding of the 19th-century medicine, and possibly even clues to the health problems of modern blacks. This article hopes to contribute to the literature by examining another source of data.

    The only proper way to describe uncertainties in health physics is by statistical means. But statistics never can replace Your personal evaluation of effect, nor can statistics transmute randomness into certainty like an ''uncertainty laundry''. The paper discusses these problems in routine practical work.

  12. Health significance and statistical uncertainty. The value of P-value.

    Science.gov (United States)

    Consonni, Dario; Bertazzi, Pier Alberto

    2017-10-27

    The P-value is widely used as a summary statistics of scientific results. Unfortunately, there is a widespread tendency to dichotomize its value in "P0.05" ("statistically not significant"), with the former implying a "positive" result and the latter a "negative" one. To show the unsuitability of such an approach when evaluating the effects of environmental and occupational risk factors. We provide examples of distorted use of P-value and of the negative consequences for science and public health of such a black-and-white vision. The rigid interpretation of P-value as a dichotomy favors the confusion between health relevance and statistical significance, discourages thoughtful thinking, and distorts attention from what really matters, the health significance. A much better way to express and communicate scientific results involves reporting effect estimates (e.g., risks, risks ratios or risk differences) and their confidence intervals (CI), which summarize and convey both health significance and statistical uncertainty. Unfortunately, many researchers do not usually consider the whole interval of CI but only examine if it includes the null-value, therefore degrading this procedure to the same P-value dichotomy (statistical significance or not). In reporting statistical results of scientific research present effects estimates with their confidence intervals and do not qualify the P-value as "significant" or "not significant".

    Full Text Available Abstract Background The importance of Small Area Variation Analysis for policy-making contrasts with the scarcity of work on the validity of the statistics used in these studies. Our study aims at 1 determining whether variation in utilization rates between health areas is higher than would be expected by chance, 2 estimating the statistical power of the variation statistics; and 3 evaluating the ability of different statistics to compare the variability among different procedures regardless of their rates. Methods Parametric bootstrap techniques were used to derive the empirical distribution for each statistic under the hypothesis of homogeneity across areas. Non-parametric procedures were used to analyze the empirical distribution for the observed statistics and compare the results in six situations (low/medium/high utilization rates and low/high variability. A small scale simulation study was conducted to assess the capacity of each statistic to discriminate between different scenarios with different degrees of variation. Results Bootstrap techniques proved to be good at quantifying the difference between the null hypothesis and the variation observed in each situation, and to construct reliable tests and confidence intervals for each of the variation statistics analyzed. Although the good performance of Systematic Component of Variation (SCV, Empirical Bayes (EB statistic shows better behaviour under the null hypothesis, it is able to detect variability if present, it is not influenced by the procedure rate and it is best able to discriminate between different degrees of heterogeneity. Conclusion The EB statistics seems to be a good alternative to more conventional statistics used in small-area variation analysis in health service research because of its robustness.

    Strengthening the information support for decision making has been identified as an important first step toward improving the efficiency, effectiveness, and equitability of the health care system in the Philippines. A Philippine-German Cooperation is in partnership toward developing a need-responsive and cost-effective Health and Management Information System (HAMIS). Four information baskets are being strengthened specifically to address these needs in a cost-effective way: public health information systems, hospital information systems, information systems on economics and financing, information systems on good health care management. BLACKBOX is the management information system for public health programs, vital statistics, mortality and notifiable diseases of the Philippines. It handles and retrieves all data that is being collected by public health workers routinely all over the Philippines. The eventual aim of BLACKBOX is to encourage the development of an information culture in which health managers actively utilise information for rational planning and decision making for a knowledge based health care delivery.

    The Act for the Protection of Personal Information in Japan considers as personal information any quasi-identifier that may be used to obtain information that identifies individuals through comparisons with datasets. Studies using health records are not widely conducted because of the concern regarding the safety of anonymized health records. To increase the safety of such records, we used the Pk-anonymity method. In this method, attributes are probabilistically randomized and then reconstructions are performed on the basis of statistical information from perturbed data. Hence, it is expected to provide more precise statistics and more reliably preserve privacy than the traditional "k-anonymity" method. We anonymized health records, performed cross tabulation, and assessed the error rate using original data. This study shows that the Pk-anonymity method can be used to perform safety statistical disclosures with low error rates, even in small cases.

    2014-01-25

    The Canadian Community Health Survey (CCHS) is a cross-sectional survey that has collected information on health determinants, health status and the utilization of the health system in Canada since 2001. Several hundred articles have been written utilizing the CCHS dataset. Previous analyses of statistical methods utilized in the literature have focused on a particular journal or set of journals to understand the statistical literacy required for understanding the published research. In this study, we describe the statistical methods referenced in the published literature utilizing the CCHS dataset(s). A descriptive study was undertaken of references published in Medline, Embase, Web of Knowledge and Scopus associated with the CCHS. These references were imported into a Java application utilizing the searchable Apache Lucene text database and screened based upon pre-defined inclusion and exclusion criteria. Full-text PDF articles that met the inclusion criteria were then used for the identification of descriptive, elementary and regression statistical methods referenced in these articles. The identification of statistical methods occurred through an automated search of key words on the full-text articles utilizing the Java application. We identified 4811 references from the 4 bibliographical databases for possible inclusion. After exclusions, 663 references were used for the analysis. Descriptive statistics such as means or proportions were presented in a majority of the articles (97.7%). Elementary-level statistics such as t-tests were less frequently referenced (29.7%) than descriptive statistics. Regression methods were frequently referenced in the articles: 79.8% of articles contained reference to regression in general with logistic regression appearing most frequently in 67.1% of the articles. Our study shows a diverse set of analysis methods being referenced in the CCHS literature, however, the literature heavily relies on only a subset of all possible

    This study applied open source technology to establish a subject-enabled analytics model that can enhance measurement statistics of case studies with the public health data in cloud computing. The infrastructure of the proposed model comprises three domains: 1) the health measurement data warehouse (HMDW) for the case study repository, 2) the self-developed modules of online health risk information statistics (HRIStat) for cloud computing, and 3) the prototype of a Web-based process automation system in statistics (PASIS) for the health risk assessment of case studies with subject-enabled evaluation. The system design employed freeware including Java applications, MySQL, and R packages to drive a health risk expert system (HRES). In the design, the HRIStat modules enforce the typical analytics methods for biomedical statistics, and the PASIS interfaces enable process automation of the HRES for cloud computing. The Web-based model supports both modes, step-by-step analysis and auto-computing process, respectively for preliminary evaluation and real time computation. The proposed model was evaluated by computing prior researches in relation to the epidemiological measurement of diseases that were caused by either heavy metal exposures in the environment or clinical complications in hospital. The simulation validity was approved by the commercial statistics software. The model was installed in a stand-alone computer and in a cloud-server workstation to verify computing performance for a data amount of more than 230K sets. Both setups reached efficiency of about 10 5 sets per second. The Web-based PASIS interface can be used for cloud computing, and the HRIStat module can be flexibly expanded with advanced subjects for measurement statistics. The analytics procedure of the HRES prototype is capable of providing assessment criteria prior to estimating the potential risk to public health. Copyright © 2017 Elsevier B.V. All rights reserved.

    The study assesses the presence and magnitude of global trends in health tourism using health-related travel (HRT) spending reported in the International Monetary Fund's Balance of Payments Statistics database. Linear regression and quantile regression are applied to estimate secular trends of the import and export of HRT based on a sample of countries from 2003 to 2009. The results show that from 2003 to 2009 the import and export of health tourism rose among countries with a high volume of such activities (accounting for the upper 40% of the countries), but not among those with a low volume. The uneven growth in health tourism has generated greater contrast between countries with high and low volumes of health tourism activities. However, the growth in the total import of health tourism did not outpace the population growth, implying that in general the population's tendency to engage in health tourism remained static.

    2003-04-01

    The Annual Statistics of Medical School Libraries in the United States and Canada (Annual Statistics) is the most recognizable achievement of the Association of Academic Health Sciences Libraries in its history to date. This article gives a thematic history of the Annual Statistics, emphasizing the leadership role of editors and Editorial Boards, the need for cooperation and membership support to produce comparable data useful for everyday management of academic medical center libraries and the use of technology as a tool for data gathering and publication. The Annual Statistics' origin is recalled, and survey features and content are related to the overall themes. The success of the Annual Statistics is evident in the leadership skills of the first editor, Richard Lyders, executive director of the Houston Academy of Medicine-Texas Medical Center Library. The history shows the development of a survey instrument that strives to produce reliable and valid data for a diverse group of libraries while reflecting the many complex changes in the library environment. The future of the Annual Statistics is assured by the anticipated changes facing academic health sciences libraries, namely the need to reflect the transition from a physical environment to an electronic operation.

    Reorganization of nurses' work has raised questions about the effects of working conditions on their health. Nurses, for example, are more likely to miss work because of illness and disability than employees in other occupations. The overall purpose of this descriptive study was to investigate the feasibility of using existing Statistics Canada surveys regularly to describe and monitor the health and working conditions of nurses. Our findings identified significant limitations in existing Statistics Canada surveys, for the study of nurses, including nonspecific or no occupational coding, small samples and partial content related to the work environment. As a result, some estimates would need to be accompanied by statements indicating that the findings do not meet quality standards and that the conclusions would be unreliable and most likely invalid. Additional data are required for a comprehensive assessment of the health status of nurses and the work environment factors that influence their health. These data can be obtained through several vehicles, including using over-sampling strategies for extant and recurring Statistics Canada surveys, adding additional content to those surveys or implementing new surveys specific to nurses and their work. The authors describe the advantages and disadvantages of each of these approaches and conclude that monitoring the health and work environment of nurses in Canada in sufficient detail to inform policy decisions requires a dedicated national survey.

    In this Series paper, we examine whether well functioning civil registration and vital statistics (CRVS) systems are associated with improved population health outcomes. We present a conceptual model connecting CRVS to wellbeing, and describe an ecological association between CRVS and health outcomes. The conceptual model posits that the legal identity that civil registration provides to individuals is key to access entitlements and services. Vital statistics produced by CRVS systems provide essential information for public health policy and prevention. These outcomes benefit individuals and societies, including improved health. We use marginal linear models and lag-lead analysis to measure ecological associations between a composite metric of CRVS performance and three health outcomes. Results are consistent with the conceptual model: improved CRVS performance coincides with improved health outcomes worldwide in a temporally consistent manner. Investment to strengthen CRVS systems is not only an important goal for individuals and societies, but also a development imperative that is good for health. Copyright © 2015 Elsevier Ltd.

    To identify key data sources of health information and describe their availability in countries of the World Health Organization (WHO) African Region. An analytical review on the availability and quality of health information data sources in countries; from experience, observations, literature and contributions from countries. Forty-six Member States of the WHO African Region. No participants. The state of data sources, including censuses, surveys, vital registration and health care facility-based sources. In almost all countries of the Region, there is a heavy reliance on household surveys for most indicators, with more than 121 household surveys having been conducted in the Region since 2000. Few countries have civil registration systems that permit adequate and regular tracking of mortality and causes of death. Demographic surveillance sites function in several countries, but the data generated are not integrated into the national health information system because of concerns about representativeness. Health management information systems generate considerable data, but the information is rarely used because of concerns about bias, quality and timeliness. To date, 43 countries in the Region have initiated Integrated Disease Surveillance and Response. A multitude of data sources are used to track progress towards health-related goals in the Region, with heavy reliance on household surveys for most indicators. Countries need to develop comprehensive national plans for health information that address the full range of data needs and data sources and that include provision for building national capacities for data generation, analysis, dissemination and use. © The Royal Society of Medicine.

    The health and nutritional status of women of reproductive age has tremendous impact on the health of future populations; therefore, special attention should be paid to promoting women's health, especially a healthy weight at this critical time period. The purpose of the paper is to provide information on the nutritional needs of women at various stages of the reproductive age spectrum, including preconception/interconception and during pregnancy to achieve and maintain a healthy weight. The Socio-Ecological Model (SEM) is presented to help practitioners understand the importance of intervening where women of reproductive age live, work, and frequent.

    2013-12-01

    Universal access to health care in most western European countries has been a given for many decades; however, macroeconomic developments and increased pressure on health care budgets could mean the status quo cannot be maintained. As populations age, a declining proportion of economically active citizens are being required to support a larger burden of health and social care, while increasing availability of novel technologies for extending and improving life continues to push health care costs upwards. With health expenditure continuing to rise as a proportion of national income, concerns are raised about the current and future financial sustainability of Organisation for Economic Co-Operation and Development (OECD) health care systems. Against this backdrop, a discussion about options to fund health care in the future, including whether to raise additional health care finance (and the ways to do so), reallocate resources and/or ration services becomes very pertinent. This study elicits preferences among a group of key stakeholders (payers, providers, government, academia and health-related industry) on the issue of health care financial sustainability and the future funding of health care services, with a view to understanding the different degrees of acceptability between policy interventions and future funding options as well as their feasibility. We invited 842 individuals from academia, other research organisations (eg. think tanks), national health services, providers, health insurance organisations, government representatives and health-related industry and related advisory stakeholders to participate in an online survey collecting preferences on a variety of revenue-generating mechanisms and cost/demand reducing policies. Respondents represented the 28 EU member states as well as Norway, Iceland, Switzerland, Australia, Russian Federation, Canada and New Zealand. We received 494 responses to our survey from all stakeholder groups. Across all groups, the

    The aim of this study was to evaluate professional socialization of nurses and its association with assurance of practice activity. The study was carried out in randomly selected Lithuanian health care institutions from January to June 2007. A total of 1300 nurses, enrolled in the study, were divided into three groups according to the position held by participants: general practice nurses, 77.8%; senior nurses and leaders, 10.7%; and 4th-year students of general nurse education program, 11.5%. A questionnaire-based survey was carried out. The data were processed with SPSS 15.0 statistical software. Descriptive and multidimensional statistical methods were applied in the study. The matrix model, integrating characteristics of nurses' professional socialization and dimensions of practice activity and disclosing parameters and indicators of assurance of these processes, was applied for data analysis. The respondents favorably evaluated the aspects ensuring professional socialization and practice activity such as "professional activity," "motivators of professional activity," "professional characteristic," "system of professional values," and "professional behavior." The respondents unfavorably evaluated the following parameters: "security of professional self-expression and self-education," "professional development," "professional expectations," and "implementation of institution strategies." For the evaluation of nurses' professional socialization and practice activity, a theoretical model was created, and nine diagnostic criteria, integrating the characteristics of professional socialization and dimensions of practice activity, were formulated. A significant positive correlation was determined among the majority of the diagnostic criteria of the intercorrelation matrix of theoretical model. Having summarized the attitude of nurses toward professional socialization and the provision of practice activity, both favorable and unfavorable aspects of assessment

    Full Text Available In recent years, it has become possible to introduce health science students to statistical packages at an increasingly early stage in their undergraduate studies. This has enabled teaching to take place in a computer laboratory, using real data, and encouraging an exploratory and research-oriented approach. This paper briefly describes a hypertext Computer Based Tutorial (CBT concerned with descriptive statistics and introductory data analysis. The CBT has three primary objectives: the introduction of concepts, the facilitation of revision, and the acquisition of skills for project work. Objective testing is incorporated and used for both self-assessment and formal examination. Evaluation was carried out with a large group of Health Science students, heterogeneous with regard to their IT skills and basic numeracy. The results of the evaluation contain valuable lessons.

    In the World Health Organization Western Pacific Region, the high rates of births attended by skilled health personnel (SHP) do not equal access to quality maternal or newborn care. 'A healthy start for every newborn' for 23 million annual births in the region means that SHP and newborn care providers give quality intrapartum, postpartum and newborn care. WHO and the UNICEF Regional Action Plan for Healthy Newborn Infants provide a platform for countries to scale-up Early Essential Newborn Care (EENC). The plan emphasises the creation of an enabling environment for the practice of EENC; thereby, preventing 50,000 newborn deaths annually. © 2014 Royal College of Obstetricians and Gynaecologists.

    Health is intertwined with human rights as is clearly reflected in the right to life. Promotion of health practices in the context of human rights can be accomplished if there is a better understanding of the level of human rights observance. In this paper, we evaluate and present an appraisal for a possibility of applying household survey to study the determinants of health and human rights and also derive the probability that human rights are observed; an important ingredient into the national planning framework. Data from the Uganda National Governance Baseline Survey were used. A conceptual framework for predictors of a hybrid dependent variable was developed and both bivariate and multivariate statistical techniques employed. Multivariate post estimation computations were derived after evaluations of the significance of coefficients of health and human rights predictors. Findings, show that household characteristics of respondents considered in this study were statistically significant (p human rights observance. For example, a unit increase of respondents' schooling levels results in an increase of about 34% level of positively assessing human rights observance. Additionally, the study establishes, through the three models presented, that household assessment of health and human rights observance was 20% which also represents how much of the entire continuum of human rights is demanded. Findings propose important evidence for monitoring and evaluation of health in the context human rights using household survey data. They provide a benchmark for health and human rights assessments with a focus on international and national development plans to achieve socio-economic transformation and health in society.

  14. Ineffable Cultures or Material Devices: What Valuation Studies can Learn from the Disappearance of Ensured Solidarity in a Health Care Market

    Directory of Open Access Journals (Sweden)

    Teun Zuiderent-Jerak

    2015-10-01

    Full Text Available Valuation studies addresses how values are made in valuation practices. A next - or rather previous - question becomes: what then makes valuation practices? Two oppositional replies are starting to dominate how that question can be answered: a more materially oriented focus on devices of valuation and a more sociologically inclined focus on ineffable valuation cultures. The debate between proponents of both approaches may easily turn into the kind of leapfrog debates that have dominated many previous discussions on whether culture or materiality would play a decisive role in driving history. This paper explores a less repetitive reply. It does so by analyzing the puzzling case of the demise of solidarity as a core value within the recent Dutch health care system of regulated competition. While "solidarity among the insured" was both a strong cultural value within the Dutch welfare-based health system, and a value that was built into market devices by health economists, within a fairly short time "fairness" became of lesser importance than "competition". This makes us call for a more historical, relational, and dynamic understanding of the role of economists, market devices, and of culture in valuation studies.

    2015-01-01

    The purpose of this article was to reflect on the concepts of adolescence and youth, summarize models and frameworks developed to conceptualize youth participation, and assess research that has attempted to evaluate the implementation and impact of youth participation in the field of sexual and reproductive health and rights (SRHR). We searched and critically reviewed relevant published reports and "gray literature" from the period 2000-2013. "Young people" are commonly defined as those between the ages of 10 and 24 years, but what it means to be a young person varies largely across cultures and depends on a range of socioeconomic factors. Several conceptual frameworks have been developed to better understand youth participation, and some frameworks are designed to monitor youth development programs that have youth participation as a key component. Although none of them are SRHR specific, they have the potential to be adapted and applied also for adolescents' SRHR programs. The most monitored and evaluated intervention type is peer education programs, but the effectiveness of the approach is questioned. There are few attempts to systematically evaluate youth participation, and clear indicators and better methodologies still need to be developed. More research and documentation as well as the adoption of innovative practices for involving youth in sexual and reproductive health programs are needed. Participation is a right and should not only be evaluated in terms of effectiveness and impact. Youth participation in program and policy development should still be a priority.

    Full Text Available In this article the reasons of the environment quality deterioration, inclu¬ding its component - water are considered, as well as methods to resolve this problem are offered. High quality of life provides for high economic and social standards, including public health. The share of environmental quality impact on morbidity rate reaches 25%, while the role of water is extremely important. At present medicine does not yet have data on the interactions between different types of diseases and water chemical composition. We need to know the impact of each indicator of water quality on health and human lifespan. In Ukraine about 25 million of population, as well as industrial and agricultural enterprises meet their needs of the water at the expense of the Dnieper river basin. As a result of construction of six extra-large reservoirs they overregulated flow of the river, which led to serious contamination of the water and catastrophic consequences for the ecosystem. Proportion of shallow water constantly increases due to siltation of reservoirs. One of the major challenges is to provide population with qualitative natural water resources. Nature prompts effective solutions. For example, water passes through the natural barriers and is purified from biofouling. A widespread prohibition on discharging untreated water into reservoirs and total transition to water recycling technologies may significantly reduce chemical contamination.

    Objective. Effectively addressing health disparities experienced by sexual minority populations requires high-quality official data on sexual orientation. We developed a conceptual framework of sexual orientation to improve the quality of sexual orientation data in New Zealand's Official Statistics System. Methods. We reviewed conceptual and methodological literature, culminating in a draft framework. To improve the framework, we held focus groups and key-informant interviews with sexual minority stakeholders and producers and consumers of official statistics. An advisory board of experts provided additional guidance. Results. The framework proposes working definitions of the sexual orientation topic and measurement concepts, describes dimensions of the measurement concepts, discusses variables framing the measurement concepts, and outlines conceptual grey areas. Conclusion. The framework proposes standard definitions and concepts for the collection of official sexual orientation data in New Zealand. It presents a model for producers of official statistics in other countries, who wish to improve the quality of health data on their citizens. PMID:23840231

    This study attempts to advance theorizing about health policy advocacy with combinations of narrative focus and a statistical map in an attempt to increase state legislators' support for policies to address the issue of obesity by reducing food deserts. Specifically, we examine state legislators' responses to variations in narrative focus (individual vs. community) about causes and solutions for food deserts in U.S. communities, and a statistical map (presence vs. absence) depicting the prevalence of food deserts across the United States. Using a Web-based randomized experiment (N=496), we show that narrative focus and the statistical map interact to produce different patterns of cognitive response and support for policies to reduce the prevalence of food deserts. The presence of a statistical map showing the prevalence of food deserts in the United States appeared to matter only when combined with an individual narrative, offsetting the fact that the individual narrative in isolation produced fewer thoughts consistent with the story's persuasive goal and more counterarguments in opposition to environmental causes and solutions for obesity than other message conditions. The image did not have an impact when combined with a story describing a community at large. Cognitive responses fully mediated message effects on intended persuasive outcomes. We conclude by discussing the study's contributions to communication theory and practice.

    Smoking, diet, exercise, and alcohol are leading causes of chronic disease and premature death, many engage in two or more of these behaviours concurrently. The paper identified statistical approaches used to investigate multiple behavioural risk factors. A scoping review of papers published in English from 2000 to 2011 was conducted; papers are related to concurrent participation in at least two of the behaviours. Statistical approaches were recorded and categorised. Across 50 papers, two distinct approaches were identified. Co-occurrence analyses focused on concurrent but independent behaviours, represented by prevalence of behavioural combinations and/or by the summing behaviours into risk indexes. Clustering analyses investigated underlying associations between the concurrent behaviours, with clustering identified by divergences in observed and expected prevalence of combinations or through identification of latent or unobservable clusters. Co-occurrence was more frequently reported, but the use of clustering techniques and, in particular, cluster analytic and latent variable techniques increased across the study period. The two approaches investigate concurrent participation in multiple health behaviours but differ in conceptualisation and analysis. Despite differences, inconsistency in the terminology describing the study of multiple health behaviours was apparent, with potential to influence understandings of concurrent health behaviours in policy and practice.

    2013-02-01

    Having sufficient power to detect effect sizes of an expected magnitude is a core consideration when designing studies in which inferential statistics will be used. The main aim of this study was to investigate the statistical power in studies published in the International Journal of Mental Health Nursing. From volumes 19 (2010) and 20 (2011) of the journal, studies were analysed for their power to detect small, medium, and large effect sizes, according to Cohen's guidelines. The power of the 23 studies included in this review to detect small, medium, and large effects was 0.34, 0.79, and 0.94, respectively. In 90% of papers, no adjustments for experiment-wise error were reported. With a median of nine inferential tests per paper, the mean experiment-wise error rate was 0.51. A priori power analyses were only reported in 17% of studies. Although effect sizes for correlations and regressions were routinely reported, effect sizes for other tests (χ(2)-tests, t-tests, ANOVA/MANOVA) were largely absent from the papers. All types of effect sizes were infrequently interpreted. Researchers are strongly encouraged to conduct power analyses when designing studies, and to avoid scattergun approaches to data analysis (i.e. undertaking large numbers of tests in the hope of finding 'significant' results). Because reviewing effect sizes is essential for determining the clinical significance of study findings, researchers would better serve the field of mental health nursing if they reported and interpreted effect sizes. © 2012 The Authors.

    Two of the most commonly used nosological systems- International Statistical Classification of Diseases and Related Health Problems (ICD)-10 and Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV are under revision. This process has generated a lot of interesting debates with regards to future of the current diagnostic categories. In fact, the status of categorical approach in the upcoming versions of ICD and DSM is also being debated. The current article focuses on the debate with regards to the eating disorders. The existing classification of eating disorders has been criticized for its limitations. A host of new diagnostic categories have been recommended for inclusion in the upcoming revisions. Also the structure of the existing categories has also been put under scrutiny.

  10. Ensure that you are well aware of the risks you are taking…”: actions and activities medical tourists’ informal caregivers can undertake to protect their health and safety

    Directory of Open Access Journals (Sweden)

    2017-05-01

    Full Text Available Abstract Background When seeking care at international hospitals and clinics, medical tourists are often accompanied by family members, friends, or other caregivers. Such caregiver-companions assume a variety of roles and responsibilities and typically offer physical assistance, provide emotional support, and aid in decision-making and record keeping as medical tourists navigate unfamiliar environments. While traveling abroad, medical tourists’ caregiver-companions can find themselves confronted with challenging communication barriers, financial pressures, emotional strain, and unsafe environments. Methods To better understand what actions and activities medical tourists’ informal caregivers can undertake to protect their health and safety, 20 interviews were conducted with Canadians who had experienced accompanying a medical tourist to an international health care facility for surgery. Interview transcripts were subsequently used to identify inductive and deductive themes central to the advice research participants offered to prospective caregiver-companions. Results Advice offered to future caregiver-companions spanned the following actions and activities to protect health and safety: become an informed health care consumer; assess and avoid exposure to identifiable risks; anticipate the care needs of medical tourists and thereby attempt to guard against caregiver burden; become familiar with important logistics related to travel and anticipated recovery timelines; and take practical measures to protect one’s own health. Conclusion Given that a key feature of public health is to use research findings to develop interventions and policies intended to promote health and reduce risks to individuals and populations, the paper draws upon major points of advice offered by study participants to take the first steps toward the development of an informational intervention designed specifically for the health and safety needs of medical tourists

  11. Controlling Time-Dependent Confounding by Health Status and Frailty: Restriction Versus Statistical Adjustment.

    McGrath, Leah J; Ellis, Alan R; Brookhart, M Alan

    Nonexperimental studies of preventive interventions are often biased because of the healthy-user effect and, in frail populations, because of confounding by functional status. Bias is evident when estimating influenza vaccine effectiveness, even after adjustment for claims-based indicators of illness. We explored bias reduction methods while estimating vaccine effectiveness in a cohort of adult hemodialysis patients. Using the United States Renal Data System and linked data from a commercial dialysis provider, we estimated vaccine effectiveness using a Cox proportional hazards marginal structural model of all-cause mortality before and during 3 influenza seasons in 2005/2006 through 2007/2008. To improve confounding control, we added frailty indicators to the model, measured time-varying confounders at different time intervals, and restricted the sample in multiple ways. Crude and baseline-adjusted marginal structural models remained strongly biased. Restricting to a healthier population removed some unmeasured confounding; however, this reduced the sample size, resulting in wide confidence intervals. We estimated an influenza vaccine effectiveness of 9% (hazard ratio = 0.91, 95% confidence interval: 0.72, 1.15) when bias was minimized through cohort restriction. In this study, the healthy-user bias could not be controlled through statistical adjustment; however, sample restriction reduced much of the bias. © The Author 2015.

    2017-08-01

    Due to the changes in living conditions and other factors many critical health related problems are arising. The diagnosis of the problem at earlier stages will increase the chances of survival and fast recovery. This reduces the time of recovery and the cost associated for the treatment. One such medical related issue is cancer and breast cancer has been identified as the second leading cause of cancer death. If detected in the early stage it can be cured. Once a patient is detected with breast cancer tumor, it should be classified whether it is cancerous or non-cancerous. So the paper uses k-nearest neighbors(KNN) algorithm which is one of the simplest machine learning algorithms and is an instance-based learning algorithm to classify the data. Day-to -day new records are added which leds to increase in the data to be classified and this tends to be big data problem. The algorithm is implemented in R whichis the most popular platform applied to machine learning algorithms for statistical computing. Experimentation is conducted by using various classification evaluation metric onvarious values of k. The results show that the KNN algorithm out performes better than existing models.

  13. "She'll be right"? National identity explanations for poor sexual health statistics in Aotearoa/New Zealand.

    Science.gov (United States)

    Braun, Virginia

    2008-12-01

    The sexual health statistics around sexually transmitted infections (STIs) in Aotearoa (New Zealand) suggest two things: many STIs are increasing, and the STI rates are high compared to other 'similar' countries. What sense do ordinary New Zealanders make of these figures? Focusing on heterosexual sex, this paper discusses lay accounts that sought to make sense of Aotearoa's STI statistics. In total, 58 participants (38 women, 20 men) aged 16-36 years (mean age 25) took part in 15 focus group discussions related to sexual health. Participants were mostly Pākehā (of European ancestry) and heterosexual. Data were analysed thematically. The predominant category of explanation was national 'identity' accounts. National 'identity' explanations invoked a particular New Zealand persona to explain the sexual health statistics. New Zealanders were characterised, sometimes contradictorily, as binge drinkers; poor communicators; self-sufficient and stoic; conservative yet highly and complacently sexual; and 'laid back', which was associated with a lack of personal concern about sexual health risk. The emphasis on national identity shifts responsibility for sexual health from the individual, and suggests agency lies beyond the individual, who is fully embedded in their culture and acts according to its dictates. In terms of sexual health, this suggests a need to consider whether, and if so how, national 'identity' might be meaningfully invoked and deployed in sexual health promotion initiatives.

  17. Two pathways ensuring social harmony

    Konrad, Matthias; Pamminger, Tobias; Foitzik, Susanne

    2012-08-01

    Reproductive division of labour is a characteristic trait of social insects. The dominant reproductive individual, often the queen, uses chemical communication and/or behaviour to maintain her social status. Queens of many social insects communicate their fertility status via cuticle-bound substances. As these substances usually possess a low volatility, their range in queen-worker communication is potentially limited. Here, we investigate the range and impact of behavioural and chemical queen signals on workers of the ant Temnothorax longispinosus. We compared the behaviour and ovary development of workers subjected to three different treatments: workers with direct chemical and physical contact to the queen, those solely under the influence of volatile queen substances and those entirely separated from the queen. In addition to short-ranged queen signals preventing ovary development in workers, we discovered a novel secondary pathway influencing worker behaviour. Workers with no physical contact to the queen, but exposed to volatile substances, started to develop their ovaries, but did not change their behaviour compared to workers in direct contact to the queen. In contrast, workers in queen-separated groups showed both increased ovary development and aggressive dominance interactions. We conclude that T. longispinosus queens influence worker ovary development and behaviour via two independent signals, both ensuring social harmony within the colony.

    Ancilla Systems, Inc., Elk Grove Village, Il, developed a mission-based performance evaluation program to provide tangible evidence of mission fulfillment and ensure the provision of high-quality healthcare. the program--Characteristics of Service--translates the language of healthcare action and evaluates corporate culture to ensure that it fulfills the expectations of its sponsor. The nine Characteristics of Service are: Respect for the dignity of all persons. Orientation toward the family unit. Quality and personalized services. Local health systems with a spectrum of services responsive to the unique needs of the community. Formal and informal partnerships with physicians. Active participation and collaboration with related community service agencies and other healthcare providers. Faithfulness to Catholic identity through close relationships with Church and religious institute resources. Effective political advocacy through education. Research and development of innovative approaches to healthcare. In establishing the behavior standards that would exemplify the characteristics, program developers used terms that correspond to specific, observable, measurable performance. All healthcare facilities are evaluated on how well they meet the behavior standards. The evaluation process includes data collection, analysis, and a final report. Data collection begins with a review of regular hospital-conducted surveys, which provide quantifiable information to measure performance against key expected behaviors. Additional data are derived from medical staff development plans and the monthly quality assurance audit. On-site surveys fill information gaps that remain after all written reports are collected.

    Full Text Available Background: For better performance, it is crucial to continuously improve quality and patient safety based on the science of quality and patient safety and the usage of appropriate tools such as statistical process control. The aim of this article is to describe statistical process control in the continuous improvement of healthcare processes.Methods: Patient falls and surgical site infections were studied using a run chart, u-chart, and g-chart.Results: In the case of patient falls special causes of variation were depicted.However, these are only statistical conclusions, whereas the content of the causes can be found only by those who work in the process of fall prevention.In the case of surgical site infection, the use of a new wound covering material was abandoned because the g-chart showed failure to improve the process. The g-chart showed that a different type of preparation of the surgical site with hair cutting instead of shaving showed a decrease in infection rates.Conclusion: Statistical process control can differentiate between common and special causes of process variability. The importance of this distinction is in the employment of different strategies for process improvement.

    Eriksson, Bo

    2015-08-01

    The Nordic School of Public Health (NHV) was jointly founded in 1953 by the Nordic countries. Until 1979, the school provided ad hoc courses on public health topics, using external teachers drawn mainly from the Nordic countries. At the time, the permanent staff of the school was small. In 1979, it began a Master's degree programme and a few academic positions were established and filled, to support these courses. The programme included four main areas: Epidemiology, Social Medicine, Environmental Health and Health Services Administration. Epidemiology was compulsory in all Master of Public Health (MPH) exams, but there were a handful of optional courses that could be substituted for the other subjects.This paper tells the story of Epidemiology at NHV from about 1980, up until closure of the school in 2014. The original MPH model ran until 1995. Nursing Science entered NHV from about 1985 and worked mainly with qualitative research that often focused on individual patients. The new methods attracted nurses, midwives, psychologists and other groups that previously had been less represented in NHV. Being quantitative and population oriented, Epidemiology lost its unique position as a mandatory subject for the MPH examination. In addition the 'New Public Health' proposed by the World Health Organisation (WHO) that advocated health promotion and the philosophy of salutogenesis became a challenge for the programme in epidemiology: pathogenesis no longer was of primary interest. From 1995, the MPH format changed repeatedly and a DrPH programme was begun. For the last 8 years of its existence, NHV offered a reasonably comprehensive, basic course in Epidemiology.Throughout the years, epidemiology training and research at NHV were very traditional. In being a relatively free institution in terms of academic choices, NHV should have contributed to the development and innovation of epidemiology in public health. For several reasons, this did not happen. © 2015 the Nordic

    Starace, Fabrizio; Mungai, Francesco; Barbui, Corrado

    2018-01-01

    In mental healthcare, one area of major concern identified by health information systems is variability in antipsychotic prescribing. While most studies have investigated patient- and prescriber-related factors as possible reasons for such variability, no studies have investigated facility-level characteristics. The present study ascertained whether staffing level is associated with antipsychotic prescribing in community mental healthcare. A cross-sectional analysis of data extracted from the Italian national mental health information system was carried out. For each Italian region, it collects data on the availability and use of mental health facilities. The rate of individuals exposed to antipsychotic drugs was tested for evidence of association with the rate of mental health staff availability by means of univariate and multivariate analyses. In Italy there were on average nearly 60 mental health professionals per 100,000 inhabitants, with wide regional variations (range 21 to 100). The average rate of individuals prescribed antipsychotic drugs was 2.33%, with wide regional variations (1.04% to 4.01%). Univariate analysis showed that the rate of individuals prescribed antipsychotic drugs was inversely associated with the rate of mental health professionals available in Italian regions (Kendall's tau -0.438, p = 0.006), with lower rates of antipsychotic prescriptions in regions with higher rates of mental health professionals. After adjustment for possible confounders, the total availability of mental health professionals was still inversely associated with the rate of individuals exposed to antipsychotic drugs. The evidence that staffing level was inversely associated with antipsychotic prescribing indicates that any actions aimed at decreasing variability in antipsychotic prescribing need to take into account aspects related to the organization of the mental health system.

  8. Statistical Alchemy: Conceptual Validity and Mapping to Generate Health State Utility Values.

    2017-12-01

    Mapping between non-preference- and preference-based health-related quality-of-life instruments has become a common technique for estimating health state utility values for use in economic evaluations. Despite the increased use of mapped health state utility estimates in health technology assessment and economic evaluation, the methods for deriving them have not been fully justified. Recent guidelines aim to standardise reporting of the methods used to map between instruments but do not address fundamental concerns in the underlying conceptual model. Current mapping methods ignore the important conceptual issues that arise when extrapolating results from potentially unrelated measures. At the crux of the mapping problem is a question of validity; because one instrument can be used to predict the scores on another, does this mean that the same preference for health is being measured in actual and estimated health state utility values? We refer to this as conceptual validity. This paper aims to (1) explain the idea of conceptual validity in mapping and its implications; (2) consider the consequences of poor conceptual validity when mapping for decision making in the context of healthcare resource allocation; and (3) offer some preliminary suggestions for improving conceptual validity in mapping.

    Evidence-informed health policymaking is a goal of equitable and effective health systems but occurs infrequently in reality. Past research points to the facilitating role of interpersonal relationships between policy-makers and researchers, imploring the adoption of a social network lens. This study aims to identify network-level factors associated with the exchange and use of research evidence in policymaking. Data on social networks and research use were collected from seventy policy actors across three health policy cases in Burkina Faso (child health, malaria, and HIV). Networks were graphed for actors' interactions, their provision of, and request for research evidence. Exponential random graph models estimated the probability of evidence provision and request between actors, controlling for network- and individual-level covariates. Logistic regression models estimated actors' use of research evidence to inform policy. Network structure explained more than half of the evidence exchanges (ties) observed in these networks. Across all cases, a pair of actors was more likely to form a provision tie if they already had a request tie between them and visa versa (θ=6.16, presearch evidence was positively associated with their centrality (i.e., connectedness). The exchange and use of research evidence in policymaking can be partly explained by the structure of actors' networks of relationships. Efforts to support knowledge translation and evidence-informed policymaking should consider network factors.

  11. Statistical challenges in modelling the health consequences of social mobility: the need for diagonal reference models.

    Various studies on the health consequences of socio-economic position address social mobility. They aim to uncover whether health outcomes are affected by: (1) social mobility, besides, (2) social origin, and (3) social destination. Conventional methods do not, however, estimate these three effects separately, which may produce invalid conclusions. We highlight that diagonal reference models (DRMs) overcome this problem, which we illustrate by focusing on overweight/obesity (OWOB). Using conventional methods (logistic-regression analyses with dummy variables) and DRMs, we examine the effects of intergenerational educational mobility on OWOB (BMI ≥ 25 kg/m 2 ) using survey data representative of the Dutch population aged 18-45 (1569 males, 1771 females). Conventional methods suggest that mobility effects on OWOB are present. Analyses with DRMs, however, indicate that no such effects exist. Conventional analyses of the health consequences of social mobility may produce invalid results. We, therefore, recommend the use of DRMs. DRMs also validly estimate the health consequences of other types of social mobility (e.g. intra- and intergenerational occupational and income mobility) and status inconsistency (e.g. in educational or occupational attainment between partners).

  12. A Statistical Modeling Framework for Projecting Future Ambient Ozone and its Health Impact due to Climate Change.

    The adverse health effects of ambient ozone are well established. Given the high sensitivity of ambient ozone concentrations to meteorological conditions, the impacts of future climate change on ozone concentrations and its associated health effects are of concern. We describe a statistical modeling framework for projecting future ozone levels and its health impacts under a changing climate. This is motivated by the continual effort to evaluate projection uncertainties to inform public health risk assessment. The proposed approach was applied to the 20-county Atlanta metropolitan area using regional climate model (RCM) simulations from the North American Regional Climate Change Assessment Program. Future ozone levels and ozone-related excesses in asthma emergency department (ED) visits were examined for the period 2041-2070. The computationally efficient approach allowed us to consider 8 sets of climate model outputs based on different combinations of 4 RCMs and 4 general circulation models. Compared to the historical period of 1999-2004, we found consistent projections across climate models of an average 11.5% higher ozone levels (range: 4.8%, 16.2%), and an average 8.3% (range: -7% to 24%) higher number of ozone exceedance days. Assuming no change in the at-risk population, this corresponds to excess ozone-related ED visits ranging from 267 to 466 visits per year. Health impact projection uncertainty was driven predominantly by uncertainty in the health effect association and climate model variability. Calibrating climate simulations with historical observations reduced differences in projections across climate models.

    Learning curves are a useful way of representing the rate of learning over time. Features include an index of baseline performance (y-intercept), the efficiency of learning over time (slope parameter) and the maximal theoretical performance achievable (upper asymptote). Each of these parameters can be statistically modelled on an individual and group basis with the resulting estimates being useful to both learners and educators for feedback and educational quality improvement. In this primer, we review various descriptive and modelling techniques appropriate to learning curves including smoothing, regression modelling and application of the Thurstone model. Using an example dataset we demonstrate each technique as it specifically applies to learning curves and point out limitations.

    2013-08-01

    The 2012 Conference on Radiation and Health in Kennebunkport, Maine, USA, brought together epidemiologists, statisticians, basic scientists, and clinical scientists interested in the health effects of radiation exposure due to medical, diagnostic, occupational, and non-medical sources, to review the current status of epidemiologic and clinical research on radiation exposure in relation to risk of breast, thyroid cancer, and leukemia, cardiopulmonary events, and other late effects. Topics discussed included synergy between radiation exposure and genetic background; late effects of radiation therapy in childhood cancer survivors and several other medically exposed cohorts; leukemia risk seen in Russian and Chernobyl studies, and leukemia risk from computed tomography scans in childhood. This report summarizes the presentations at the meeting and discusses their significance in light of earlier studies and of other ongoing research.

  16. Bayesian versus frequentist statistical inference for investigating a one-off cancer cluster reported to a health department

    2009-05-01

    Full Text Available Abstract Background The problem of silent multiple comparisons is one of the most difficult statistical problems faced by scientists. It is a particular problem for investigating a one-off cancer cluster reported to a health department because any one of hundreds, or possibly thousands, of neighbourhoods, schools, or workplaces could have reported a cluster, which could have been for any one of several types of cancer or any one of several time periods. Methods This paper contrasts the frequentist approach with a Bayesian approach for dealing with silent multiple comparisons in the context of a one-off cluster reported to a health department. Two published cluster investigations were re-analysed using the Dunn-Sidak method to adjust frequentist p-values and confidence intervals for silent multiple comparisons. Bayesian methods were based on the Gamma distribution. Results Bayesian analysis with non-informative priors produced results similar to the frequentist analysis, and suggested that both clusters represented a statistical excess. In the frequentist framework, the statistical significance of both clusters was extremely sensitive to the number of silent multiple comparisons, which can only ever be a subjective "guesstimate". The Bayesian approach is also subjective: whether there is an apparent statistical excess depends on the specified prior. Conclusion In cluster investigations, the frequentist approach is just as subjective as the Bayesian approach, but the Bayesian approach is less ambitious in that it treats the analysis as a synthesis of data and personal judgements (possibly poor ones, rather than objective reality. Bayesian analysis is (arguably a useful tool to support complicated decision-making, because it makes the uncertainty associated with silent multiple comparisons explicit.

  17. Is globalization healthy: a statistical indicator analysis of the impacts of globalization on health

    2010-01-01

    It is clear that globalization is something more than a purely economic phenomenon manifesting itself on a global scale. Among the visible manifestations of globalization are the greater international movement of goods and services, financial capital, information and people. In addition, there are technological developments, more transboundary cultural exchanges, facilitated by the freer trade of more differentiated products as well as by tourism and immigration, changes in the political landscape and ecological consequences. In this paper, we link the Maastricht Globalization Index with health indicators to analyse if more globalized countries are doing better in terms of infant mortality rate, under-five mortality rate, and adult mortality rate. The results indicate a positive association between a high level of globalization and low mortality rates. In view of the arguments that globalization provides winners and losers, and might be seen as a disequalizing process, we should perhaps be careful in interpreting the observed positive association as simple evidence that globalization is mostly good for our health. It is our hope that a further analysis of health impacts of globalization may help in adjusting and optimising the process of globalization on every level in the direction of a sustainable and healthy development for all.

  18. Health and lifestyle separating the truth from the myth with statistics

    Everitt, Brian S

    2016-01-01

    The main message of this book is that people should be on their guard against both scare stories about risks to health, and claims for miracle cures of medical conditions. In the 21st century hardly a day passes without another article appearing in the media about a new treatment for a particular disease, new ways of improving our health by changing our lifestyle or new foodstuffs that claim to increase (or decrease) the risk of heart disease, cancer and the like. But how should the general public react to such claims, given that some of the journalists writing them focus on the sensational rather than the mundane and often have no qualms about sacrificing accuracy and honesty for the sake of a good story? Perhaps the wisest initial response is one of healthy scepticism, followed by an attempt to discover more about the details of the studies behind the reports. But most people are not, and have little desire to become experts in health research. By reading this book, however, these non-experts can, with mini...

    Epidemiology is concerned with determining the distribution and causes of disease. Throughout its history, epidemiology has drawn upon statistical ideas and methods to achieve its aims. Because of the exponential growth in our capacity to measure and analyze data on the underlying processes that define each person's state of health, there is an emerging opportunity for population-based epidemiologic studies to influence health decisions made by individuals in ways that take into account the individuals' characteristics, circumstances, and preferences. We refer to this endeavor as "individualized health." The present article comprises 2 sections. In the first, we describe how graphical, longitudinal, and hierarchical models can inform the project of individualized health. We propose a simple graphical model for informing individual health decisions using population-based data. In the second, we review selected topics in causal inference that we believe to be particularly useful for individualized health. Epidemiology and biostatistics were 2 of the 4 founding departments in the world's first graduate school of public health at Johns Hopkins University, the centennial of which we honor. This survey of a small part of the literature is intended to demonstrate that the 2 fields remain just as inextricably linked today as they were 100 years ago. © The Author 2016.

    Full Text Available Context. Perinatal mortality indicators are considered the most important measures of perinatal outcome. The indicators reliability depends on births and deaths reporting and recording. Many publications focus on perinatal deaths underreporting and misclassification, disabling proper international comparisons. Objective. Description of perinatal health care quality assessment key indicators in Croatia. Methods. Retrospective review of reports from all maternities from 2001 to 2014. Results. According to reporting criteria for birth weight ≥500 g, perinatal mortality (PNM was reduced by 31%, fetal mortality (FM by 32%, and early neonatal mortality (ENM by 29%. According to reporting criteria for ≥1000 g, PNM was reduced by 43%, FM by 36%, and ENM by 54%. PNM in ≥22 weeks’ (wks gestational age (GA was reduced by 28%, FM by 30%, and ENM by 26%. The proportion of FM at 32–36 wks GA and at term was the highest between all GA subgroups, as opposed to ENM with the highest proportion in 22–27 wks GA. Through the period, the maternal mortality ratio varied from 2.4 to 14.3/100,000 live births. The process indicators have been increased in number by more than half since 2001, the caesarean deliveries from 11.9% in 2001 to 19.6% in 2014. Conclusions. The comprehensive perinatal health monitoring represents the basis for the perinatal quality assessment.

    2005-01-01

    In the United States, obesity has reached epidemic proportions. Serious medical complications, impaired quality of life, and premature mortality are all associated with obesity. Medical conditions such as type 2 diabetes mellitus, hypertension, hyperlipidemia, or sleep apnea can improve or be cured with weight loss. Medical treatment programs focused on diet, behavior modification, and/or pharmacologic intervention have met with limited long-term success. Although surgical treatments for obesity have become popular in recent years, they should only be used as a last resort for weight loss. Not all patients can be considered appropriate candidates for surgery; therefore, guidelines based on criteria from the National Institutes of Health should be used preoperatively to help identify suitable persons. Most individuals who opt for weight-loss surgery have usually struggled for many years with losing weight and keeping it off, but surgery alone will not ensure successful weight loss. Patient education is imperative for long-term success. Moreover, any such educational regimen should include information on diet, vitamin and mineral supplementation, and lifestyle changes, as well as expected weight-loss results and improvements in comorbid conditions. Patients must be willing to commit to a long-term follow-up program intended to promote successful weight loss and weight maintenance and to prevent metabolic and nutritional complications.

    The construct validity and generalizability of the Mental Health Statistics Improvement Program (MHSIP) adult consumer satisfaction survey was examined using a representative sample (N = 4242) of public mental health client surveys and assessment data. Factor analysis found five factors generally supporting the hypothesized scales of Satisfaction, Outcomes-Functioning, Access, Quality, and Social Connectedness that had acceptable reliability (average coefficient alpha = 0.91). The relation of the satisfaction survey scales to clinician-rated symptom scales, hospitalization, and functioning for 3 years prior to and after the survey was examined. Correlations were modest in magnitude but were in the predicted directions, with greater patient satisfaction being associated with lower symptoms and more positive outcomes. The largest predictors of the clinician-rated symptom scales were Outcomes-Functioning and Social Connectedness.

  5. Statistical modeling of volume of alcohol exposure for epidemiological studies of population health: the US example

    2010-03-01

    Full Text Available Abstract Background Alcohol consumption is a major risk factor in the global burden of disease, with overall volume of exposure as the principal underlying dimension. Two main sources of data on volume of alcohol exposure are available: surveys and per capita consumption derived from routine statistics such as taxation. As both sources have significant problems, this paper presents an approach that triangulates information from both sources into disaggregated estimates in line with the overall level of per capita consumption. Methods A modeling approach was applied to the US using data from a large and representative survey, the National Epidemiologic Survey on Alcohol and Related Conditions. Different distributions (log-normal, gamma, Weibull were used to model consumption among drinkers in subgroups defined by sex, age, and ethnicity. The gamma distribution was used to shift the fitted distributions in line with the overall volume as derived from per capita estimates. Implications for alcohol-attributable fractions were presented, using liver cirrhosis as an example. Results The triangulation of survey data with aggregated per capita consumption data proved feasible and allowed for modeling of alcohol exposure disaggregated by sex, age, and ethnicity. These models can be used in combination with risk relations for burden of disease calculations. Sensitivity analyses showed that the gamma distribution chosen yielded very similar results in terms of fit and alcohol-attributable mortality as the other tested distributions. Conclusions Modeling alcohol consumption via the gamma distribution was feasible. To further refine this approach, research should focus on the main assumptions underlying the approach to explore differences between volume estimates derived from surveys and per capita consumption figures.

    Traditional analytic methods are often ill-suited to the evolving world of health care big data characterized by massive volume, complexity, and velocity. In particular, methods are needed that can estimate models efficiently using very large datasets containing healthcare utilization data, clinical data, data from personal devices, and many other sources. Although very large, such datasets can also be quite sparse (e.g., device data may only be available for a small subset of individuals), which creates problems for traditional regression models. Many machine learning methods address such limitations effectively but are still subject to the usual sources of bias that commonly arise in observational studies. Researchers using machine learning methods such as lasso or ridge regression should assess these models using conventional specification tests.

Frequently, the results of questioner measurements are numeric rank and index or both of them. Numeric rank and index are categorical data. Beside of validity and reliability problems, they have analytical problems as well. So, they need transformation to scale type (ratio, interval data in order to minimize their problems. Purpose: This article reviews the effectiveness of two type data transformation in dental health research measurement. reviews: There are two type data transformations, i.e. interval equivalency and sum of rating transformation method. Conclusion: Interval equivalency transformation method is more effective for the data come from index, and sum of rating transformation method is more effective for the data come from numeric rank.

    Full Text Available The aim of the systematic ensuring of knowledge continuity is the continuity of an organisation’s development, the quality of managerial positions and the continuity of decision-making. By ensuring knowledge continuity, organisations may gain a performance-enhancing factor. The objective of the article is to identify the level of impact of decisive internal factors determining knowledge continuity ensuring and contributing to the efficiency of the organisations. Knowledge continuity ensuring as an internal force, however, can together with the right employees, help adapt more quickly to external conditions that organisations can hardly control. Monitoring and ensuring knowledge continuity can contribute to a higher quality of processes in general, in particular processes exploiting knowledge, and thus help improve the level of management. The first part of the article presents theoretical views on the aspects of knowledge continuity ensuring in organisations while the second part analyses the findings of the surveys carried out among managers in organisations in the Czech Republic. Based on the summary of the outcomes obtained it is possible to say that internal factors influence knowledge continuity ensuring in organisations, however, the level of impact of individual factors is determined by their size. The findings regarding the impact of each of the factors show that the most significant barriers to knowledge continuity ensuring are those associated with the human factor.

    2013-01-01

    Objective: Libraries require efficient and reliable methods to assess journal use. Vendors provide complete counts of articles retrieved from their platforms. However, if a journal is available on multiple platforms, several sets of statistics must be merged. Link-resolver reports merge data from all platforms into one report but only record partial use because users can access library subscriptions from other paths. Citation data are limited to publication use. Vendor, link-resolver, and local citation data were examined to determine correlation. Because link-resolver statistics are easy to obtain, the study library especially wanted to know if they correlate highly with the other measures. Methods: Vendor, link-resolver, and local citation statistics for the study institution were gathered for health sciences journals. Spearman rank-order correlation coefficients were calculated. Results: There was a high positive correlation between all three data sets, with vendor data commonly showing the highest use. However, a small percentage of titles showed anomalous results. Discussion and Conclusions: Link-resolver data correlate well with vendor and citation data, but due to anomalies, low link-resolver data would best be used to suggest titles for further evaluation using vendor data. Citation data may not be needed as it correlates highly with other measures. PMID:23646026

  11. Statistically Filtering Data for Operational Modal Analysis under Ambient Vibration in Structural Health Monitoring Systems

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Operational modal analysis (OMA is prevalent in large structure modal identification for that it asks for output measurements only. To guarantee identification accuracy, theoretically, OMA data need to be a random process of Gaussian white noise (GWN. Although numerous OMA applications are found in practice, few have particularly discussed the data distribution and to what extent it would blur the modal judgement. This paper presents a method to sieve segments mostly obeying the GWN distribution out of a recording. With a windowing technique, the data segments are evaluated by the modified Kurtosis value. The process has been demonstrated on the monitoring data of two case study structures: one is a laboratory truss bridge excited by artificial forces, the other is a real cable-stayed bridge subject to environmental loads. The results show that weak randomness data may result in false peaks that would possibly mislead the non-parametric modal identification, such as using the Frequency Domain Decomposition method. To overcome, cares on selecting the optimal segment shall be exercised. The proposed method is verified effective to find the most suitable data for modal identification of structural health monitoring systems.

    2017-10-01

    The World Health Organization (WHO) is revising its diagnostic manual, the International Statistical Classification of Diseases and Related Health Problems (ICD). At the time of writing, and based on recommendations from its ICD Working Group on Sexual Disorders and Sexual Health, WHO is proposing a new ICD chapter titled Conditions Related to Sexual Health, and that the gender incongruence diagnoses (replacements for the gender identity disorder diagnoses used in ICD-10) should be placed in that chapter. WHO is proposing that there should be a Gender incongruence of childhood (GIC) diagnosis for children below the age of puberty. This last proposal has come under fire. Trans community groups, as well as many healthcare professionals and others working for transgender health and wellbeing, have criticised the proposal on the grounds that the pathologisation of gender diversity at such a young age is inappropriate, unnecessary, harmful and inconsistent with WHO's approach in regard to other aspects of development in childhood and youth. Counter proposals have been offered that do not pathologise gender diversity and instead make use of Z codes to frame and document any contacts that young gender diverse children may have with health services. The author draws on his involvement in the ICD revision process, both as a member of the aforementioned WHO Working Group and as one of its critics, to put the case against the GIC proposal, and to recommend an alternative approach for ICD in addressing the needs of gender diverse children.

CHIPRA also requires core measures to identify disparities by race and ethnicity, among other factors. State Medicaid and CHIP programs are currently facing significant budgetary pressures that are likely to increase with eligibility expansions and programmatic changes resulting from the Patient Protection and Affordable Care Act (PPACA). To limit the burden on states and increase the likelihood of states' voluntarily reporting on core pediatric quality measures, HHS may consider utilizing existing data sources. This article examines the feasibility of utilizing Medicaid Statistical Information System (MSIS) data to identify and analyze the core children's healthcare quality measures required by CHIPRA. Five key themes related to the feasibility of using MSIS as a data source for quality measures are identified: states have significant experience with data collection, performance measurement, and quality oversight for children in Medicaid and CHIP; CHIPRA provisions related to reporting of quality measures will be implemented at a time when states are facing major fiscal constraints; MSIS provides potential opportunities as it offers a rich source of data, but the difficulties in obtaining clean data should not be underestimated; MSIS has limitations; and states, the federal government, providers, and enrollees benefit from standardization in data and quality measurement.

    The validation of health economic (HE) model outcomes against empirical data is of key importance. Although statistical testing seems applicable, guidelines for the validation of HE models lack guidance on statistical validation, and actual validation efforts often present subjective judgment of graphs and point estimates. To discuss the applicability of existing validation techniques and to present a new method for quantifying the degrees of validity statistically, which is useful for decision makers. A new Bayesian method is proposed to determine how well HE model outcomes compare with empirical data. Validity is based on a pre-established accuracy interval in which the model outcomes should fall. The method uses the outcomes of a probabilistic sensitivity analysis and results in a posterior distribution around the probability that HE model outcomes can be regarded as valid. We use a published diabetes model (Modelling Integrated Care for Diabetes based on Observational data) to validate the outcome "number of patients who are on dialysis or with end-stage renal disease." Results indicate that a high probability of a valid outcome is associated with relatively wide accuracy intervals. In particular, 25% deviation from the observed outcome implied approximately 60% expected validity. Current practice in HE model validation can be improved by using an alternative method based on assessing whether the model outcomes fit to empirical data at a predefined level of accuracy. This method has the advantage of assessing both model bias and parameter uncertainty and resulting in a quantitative measure of the degree of validity that penalizes models predicting the mean of an outcome correctly but with overly wide credible intervals.

    In the developed world, information on vital events is routinely collected nationally to inform population and health policies. However, in many low-and middle-income countries, especially those in sub-Saharan Africa (SSA), there is a lack of effective and comprehensive national civil registration and vital statistics system. In the past decades, the number of Health and Demographic Surveillance Systems (HDSSs) has increased throughout SSA. An HDSS monitors births, deaths, causes of death, migration, and other health and socio-economic indicators within a defined population over time. Currently, the International Network for the Continuous Demographic Evaluation of Populations and Their Health (INDEPTH) brings together 38 member research centers which run 44 HDSS sites from 20 countries in Africa, Asia and Oceana. Thirty two of these HDSS sites are in SSA. This paper argues that, in the absence of an adequate national CRVS, HDSSs should be more effectively utilised to generate relevant public health data, and also to create local capacity for longitudinal data collection and management systems in SSA. If HDSSs get strategically located to cover different geographical regions in a country, data from these sites could be used to provide a more complete national picture of the health of the population. They provide useful data that can be extrapolated for national estimates if their regional coverage is well planned. HDSSs are however resource-intensive. Efforts are being put towards getting them linked to local or national policy contexts and to reduce their dependence on external funding. Increasing their number in SSA to cover a critical proportion of the population, especially urban populations, must be carefully planned. Strategic planning is needed at national levels to geographically locate HDSS sites and to support these through national funding mechanisms. The paper does not suggest that HDSSs should be seen as a replacement for civil registration systems

    Much variation in individual-level cognitive function in late life remains unexplained, with little exploration of area-level/contextual factors to date. Income inequality is a contextual factor that may plausibly influence cognitive function. In a nationally-representative cohort of older Americans from the Health and Retirement Study, we examined state- and metropolitan statistical area (MSA)-level income inequality as predictors of individual-level cognitive function measured by the 27-point Telephone Interview for Cognitive Status (TICS-m) scale. We modeled latency periods of 8-20 years, and controlled for state-/metropolitan statistical area (MSA)-level and individual-level factors. Higher MSA-level income inequality predicted lower cognitive function 16-18 years later. Using a 16-year lag, living in a MSA in the highest income inequality quartile predicted a 0.9-point lower TICS-m score (β = -0.86; 95% CI = -1.41, -0.31), roughly equivalent to the magnitude associated with five years of aging. We observed no associations for state-level income inequality. The findings were robust to sensitivity analyses using propensity score methods. Among older Americans, MSA-level income inequality appears to influence cognitive function nearly two decades later. Policies reducing income inequality levels within cities may help address the growing burden of declining cognitive function among older populations within the United States.

    2003-04-01

    This paper presents an exploratory trend analysis of the statistics published over the past twenty-four editions of the Annual Statistics of Medical School Libraries in the United States and Canada. The analysis focuses on the small subset of nineteen consistently collected data variables (out of 656 variables collected during the history of the survey) to provide a general picture of the growth and changing dimensions of services and resources provided by academic health sciences libraries over those two and one-half decades. The paper also analyzes survey response patterns for U.S. and Canadian medical school libraries, as well as osteopathic medical school libraries surveyed since 1987. The trends show steady, but not dramatic, increases in annual means for total volumes collected, expenditures for staff, collections and other operating costs, personnel numbers and salaries, interlibrary lending and borrowing, reference questions, and service hours. However, when controlled for inflation, most categories of expenditure have just managed to stay level. The exceptions have been expenditures for staff development and travel and for collections, which have both outpaced inflation. The fill rate for interlibrary lending requests has remained steady at about 75%, but the mean ratio of items lent to items borrowed has decreased by nearly 50%.

The theory of errors on factorial moments by Szapudi & Colombi (1996) is applied to cumulants via a series expansion method. All results are subsequently extended to the weakly non-linear regime. Together with previous investigations this yields an analytic theory of the errors for moments and connected moments of counts in cells from highly nonlinear to weakly nonlinear scales.

    The aim of this study is to develop a methodology for estimating a nationwide statistic for hernia operations with using the claim database of the Korea Health Insurance Cooperation (KHIC). According to the insurance claim procedures, the claim database was divided into the electronic data interchange database (EDI_DB) and the sheet database (Paper_DB). Although the EDI_DB has operation and management codes showing the facts and kinds of operations, the Paper_DB doesn't. Using the hernia matched management code in the EDI_DB, the cases of hernia surgery were extracted. For drawing the potential cases from the Paper_DB, which doesn't have the code, the predictive model was developed using the data mining technique called SEMMA. The claim sheets of the cases that showed a predictive probability of an operation over the threshold, as was decided by the ROC curve, were identified in order to get the positive predictive value as an index of usefulness for the predictive model. Of the claim databases in 2004, 14,386 cases had hernia related management codes with using the EDI system. For fitting the models with applying the data mining technique, logistic regression was chosen rather than the neural network method or the decision tree method. From the Paper_DB, 1,019 cases were extracted as potential cases. Direct review of the sheets of the extracted cases showed that the positive predictive value was 95.3%. The results suggested that applying the data mining technique to the claim database in the KHIC for estimating the nationwide surgical statistics would be useful from the aspect of execution and cost-effectiveness.

    We study the question of how to represent or summarize raw laboratory data taken from an electronic health record (EHR) using parametric model selection to reduce or cope with biases induced through clinical care. It has been previously demonstrated that the health care process (Hripcsak and Albers, 2012, 2013), as defined by measurement context (Hripcsak and Albers, 2013; Albers et al., 2012) and measurement patterns (Albers and Hripcsak, 2010, 2012), can influence how EHR data are distributed statistically (Kohane and Weber, 2013; Pivovarov et al., 2014). We construct an algorithm, PopKLD, which is based on information criterion model selection (Burnham and Anderson, 2002; Claeskens and Hjort, 2008), is intended to reduce and cope with health care process biases and to produce an intuitively understandable continuous summary. The PopKLD algorithm can be automated and is designed to be applicable in high-throughput settings; for example, the output of the PopKLD algorithm can be used as input for phenotyping algorithms. Moreover, we develop the PopKLD-CAT algorithm that transforms the continuous PopKLD summary into a categorical summary useful for applications that require categorical data such as topic modeling. We evaluate our methodology in two ways. First, we apply the method to laboratory data collected in two different health care contexts, primary versus intensive care. We show that the PopKLD preserves known physiologic features in the data that are lost when summarizing the data using more common laboratory data summaries such as mean and standard deviation. Second, for three disease-laboratory measurement pairs, we perform a phenotyping task: we use the PopKLD and PopKLD-CAT algorithms to define high and low values of the laboratory variable that are used for defining a disease state. We then compare the relationship between the PopKLD-CAT summary disease predictions and the same predictions using empirically estimated mean and standard deviation to a

  10. Back to the basics: Identifying and addressing underlying challenges in achieving high quality and relevant health statistics for indigenous populations in Canada.

    Science.gov (United States)

    Smylie, Janet; Firestone, Michelle

    Canada is known internationally for excellence in both the quality and public policy relevance of its health and social statistics. There is a double standard however with respect to the relevance and quality of statistics for Indigenous populations in Canada. Indigenous specific health and social statistics gathering is informed by unique ethical, rights-based, policy and practice imperatives regarding the need for Indigenous participation and leadership in Indigenous data processes throughout the spectrum of indicator development, data collection, management, analysis and use. We demonstrate how current Indigenous data quality challenges including misclassification errors and non-response bias systematically contribute to a significant underestimate of inequities in health determinants, health status, and health care access between Indigenous and non-Indigenous people in Canada. The major quality challenge underlying these errors and biases is the lack of Indigenous specific identifiers that are consistent and relevant in major health and social data sources. The recent removal of an Indigenous identity question from the Canadian census has resulted in further deterioration of an already suboptimal system. A revision of core health data sources to include relevant, consistent, and inclusive Indigenous self-identification is urgently required. These changes need to be carried out in partnership with Indigenous peoples and their representative and governing organizations.

    Objectives To analyse changes in overall readmission rates and disparities in such rates, among patients aged 18-64 (those most likely to have been affected by reform), using all payer inpatient discharge databases (hospital episode statistics) from Massachusetts and two control states (New York and New Jersey). Design Difference in differences analysis to identify the post-reform change, adjusted for secular changes unrelated to reform. Setting US hospitals in Massachusetts, New York, and New Jersey. Participants Adults aged 18-64 admitted for any cause, excluding obstetrical. Main outcome measure Readmissions at 30 days after an index admission. Results After adjustment for known confounders, including age, sex, comorbidity, hospital ownership, teaching hospital status, and nurse to census ratio, the odds of all cause readmission in Massachusetts was slightly increased compared with control states post-reform (odds ratio 1.02, 95% confidence interval 1.01 to 1.04, P<0.05). Racial and ethnic disparities in all cause readmission rates did not change in Massachusetts compared with control states. In analyses limited to Massachusetts only, there were minimal overall differences in changes in readmission rates between counties with differing baseline uninsurance rates, but black people in counties with the highest uninsurance rates had decreased odds of readmission (0.91, 0.84 to 1.00) compared with black people in counties with lower uninsurance rates. Similarly, white people in counties with the highest uninsurance rates had decreased odds of readmission (0.96, 0.94 to 0.99) compared with white people in counties with lower uninsurance rates. Conclusions In the United States, and in Massachusetts in particular, extending health insurance coverage alone seems insufficient to improve readmission rates. Additional efforts are needed to reduce hospital readmissions and disparities in this outcome. PMID:24687184

    2002-04-01

    The energy of a system which is described by a Hamiltonian which includes at most two-particle interactions can be expressed in terms of the second order reduced density matrix. However, for the 2-matrix to have proper symmetry is a weaker condition than requiring that the wavefunction be antisymmetric, which is called the N-representability problem, a problem of long term interest. Coleman [Reduced Density Matrices: Coulson's Challenge, Springer, New York, 2000] however, proposed an algorithm which ensures N-representability. In this Letter we examine the algorithm and show its connection to the full configuration interaction method and the contracted Schroedinger equation.

    STUDY OBJECTIVE--The Small Area Health Statistics Unit (SAHSU) was established at the London School of Hygiene and Tropical Medicine in response to a recommendation of the enquiry into the increased incidence of childhood leukaemia near Sellafield, the nuclear reprocessing plant in West Cumbria. The aim of this paper was to describe the Unit's methods for the investigation of health around point sources of environmental pollution in the United Kingdom. DESIGN--Routine data currently including deaths and cancer registrations are held in a large national database which uses a post code based retrieval system to locate cases geographically and link them to the underlying census enumeration districts, and hence to their populations at risk. Main outcome measures were comparison of observed/expected ratios (based on national rates) within bands delineated by concentric circles around point sources of environmental pollution located anywhere in Britain. MAIN RESULTS--The system is illustrated by a study of mortality from mesothelioma and asbestosis near the Plymouth naval dockyards during 1981-87. Within a 3 km radius of the docks the mortality rate for mesothelioma was higher than the national rate by a factor of 8.4, and that for asbestosis was higher by a factor of 13.6. CONCLUSIONS--SAHSU is a new national facility which is rapidly able to provide rates of mortality and cancer incidence for arbitrary circles drawn around any point in Britain. The example around Plymouth of mesothelioma and asbestosis demonstrates the ability of the system to detect an unusual excess of disease in a small locality, although in this case the findings are likely to be related to occupational rather than environmental exposure.

    Every pediatrician would want to satisfy their patients and their parents to sustain good practice, earn name and fame and simultaneously to avoid litigation in this era of consumer protection act. This can be achieved only by use of good communication skills. Today the patients demand time, information and want their questions to be answered. They expect politeness, empathy and human touch from doctors. Time constraints, arrogance, telephone calls, language barriers and cultural insensitivity are the important barriers to good communication. Research has shown that doctor, who undergoes training to acquire good communication skills, can better satisfy his patients. Good communication skill is an art which can be acquired or improved by putting conscious efforts in day to day practice. Such skills should also be incorporated as part of medical teaching curriculum. Asking open ended questions, effective listening, appropriate praise, providing enough information as part of advice and finally checking their understanding, are the key areas of communication during medical interview. During this process pediatrician should ensure to address the parental concerns, should empathize with parents and involve parents in decision making. This will not only ensure satisfaction of parents but also their adherence to the therapy and to the pediatrician.

    Full Text Available Relevance of the topic is determined by the need for sustainable development of the country’s banking system, capable of ensuring the process of raising funds to producers and the public for their projects. One of the implementation of this objective is to discourage unfair behavior in financial markets. Trust is a key factor in the development of financial markets, therefore it is necessary to suppress the appearance of unfair practices and participants – black creditors, falsification of financial statements, trading on insider information and market manipulation. It requires a whole range of activities, and above all ensuring the inevitability and proportionality of punishment for unscrupulous players, the introduction of requirements for the business reputation of the management of financial institutions.The article is devoted to structuring legal violations in the lending sphere. The analysis of indicators of credit organizations in Russia was conducted to fulfill this aim. This analysis revealed the causes of sustainable growth of overdue accounts payable – job cuts in enterprises, violations in the financial sector, various errors in the credit granting / raising. The authors carry out the systematization and classification of offenses in the area of lending, provide examples, as well as factual material illustrating the violations in the lending process having the characteristics of a fraud. The article substantiates the obligations of employees of the credit institution, in the result of which risks of granting credit to fraudsters can be reduced. The methods of fraud prevention should include the identified methods of protection against fraud in the area under consideration – exchange of information by banks associated with the criminal intentions of customers; technology development and technical support, training, and personnel responsibilities.

Our deformation model is a modified version of the diffeomorphic model introduced by Cootes et al....... The modifications ensure that no boundary restriction has to be enforced on the parameter space to prevent folds or tears in the deformation field. For straightforward statistical analysis, principal component analysis and sparse methods, we assume that the parameters for a class of deformations lie on a linear...

    2017-05-01

    The exponential, the normal, and the Poisson statistical laws are of major importance due to their universality. Harmonic statistics are as universal as the three aforementioned laws, but yet they fall short in their 'public relations' for the following reason: the full scope of harmonic statistics cannot be described in terms of a statistical law. In this paper we describe harmonic statistics, in their full scope, via an object termed harmonic Poisson process: a Poisson process, over the positive half-line, with a harmonic intensity. The paper reviews the harmonic Poisson process, investigates its properties, and presents the connections of this object to an assortment of topics: uniform statistics, scale invariance, random multiplicative perturbations, Pareto and inverse-Pareto statistics, exponential growth and exponential decay, power-law renormalization, convergence and domains of attraction, the Langevin equation, diffusions, Benford's law, and 1/f noise.

    the operability of the machine and tractor aggregates is ensured by processes which occur in machine units and considered as technical systems. In order to develop theoretical understanding of the processes in technical systems as the basis and purpose of the repairserving actions, the author's concept is presented which relies on on the basic concepts of "processes in technical systems", "maintenance and repair of performers", "maintenance and repair of technology" "objectives of the maintenance and repair". Analysis of the basic concepts of "processes in technical systems" made possible to distinguishing four types of relations: of order, stipulation, exactingness, and non-contradiction. It is shown that the implementation of maintenance and repair of technology should be conducted according to the assessment of the effectiveness of processes in technical systems, revealed in complex diagnosis. The perfection of the design of the machine in terms of its technical operation can be estimated according to the degree of consistency of processes in technical systems, purposes of maintenance and repair. In order to increase the efficiency of the lubrication system,the modernised design of the centrifugal oil filter with permanent control of its cleaning power is offered, which allows changing the technology of the maintenance of engine lubrication system by separating the operations of crankcase oil replacement and the rotor filter cleaning.

    Public health research on inequalities in Canada depends heavily on population data sets such as the Canadian Community Health Survey. While sexual orientation has three dimensions - identity, behaviour and attraction - Statistics Canada and public health agencies assess sexual orientation with a single questionnaire item on identity, defined behaviourally. This study aims to evaluate this item, to allow for clearer interpretation of sexual orientation frequencies and inequalities. Through an online convenience sampling of Canadians ≥14 years of age, participants (n = 311) completed the Statistics Canada question and a second set of sexual orientation questions. The single-item question had an 85.8% sensitivity in capturing sexual minorities, broadly defined by their sexual identity, lifetime behaviour and attraction. Kappa statistic for agreement between the single item and sexual identity was 0.89; with past year, lifetime behaviour and attraction were 0.39, 0.48 and 0.57 respectively. The item captured 99.3% of those with a sexual minority identity, 84.2% of those with any lifetime same-sex partners, 98.4% with a past-year same-sex partner, and 97.8% who indicated at least equal attraction to same-sex persons. Findings from Statistics Canada surveys can be best interpreted as applying to those who identify as sexual minorities. Analyses using this measure will underidentify those with same-sex partners or attractions who do not identify as a sexual minority, and should be interpreted accordingly. To understand patterns of sexual minority health in Canada, there is a need to incorporate other dimensions of sexual orientation.

  5. Building a stronger child dental health system in Australia: statistical sampling masks the burden of dental disease distribution in Australian children.

    In Australia, over the past 30 years, the prevalence of dental decay in children has reduced significantly, where today 60-70% of all 12-year-olds are caries free, and only 10% of children have more than two decayed teeth. However, many studies continue to report a small but significant subset of children suffering severe levels of decay. The present study applies Monte Carlo simulation to examine, at the national level, 12-year-old decayed, missing or filled teeth and shed light on both the statistical limitation of Australia's reporting to date as well as the problem of targeting high-risk children. A simulation for 273 000 Australian 12-year-old children found that moving from different levels of geographic clustering produced different statistical influences that drive different conclusions. At the high scale (ie state level) the gross averaging of the non-normally distributed disease burden masks the small subset of disease bearing children. At the much higher acuity of analysis (ie local government area) the risk of low numbers in the sample becomes a significant issue. The results clearly highlight the importance of care when examining the existing data, and, second, opportunities for far greater levels of targeting of services to children in need. The sustainability (and fairness) of universal coverage systems needs to be examined to ensure they remain highly targeted at disease burden, and not just focused on the children that are easy to reach (and suffer the least disease).

    The exponential, the normal, and the Poisson statistical laws are of major importance due to their universality. Harmonic statistics are as universal as the three aforementioned laws, but yet they fall short in their ‘public relations’ for the following reason: the full scope of harmonic statistics cannot be described in terms of a statistical law. In this paper we describe harmonic statistics, in their full scope, via an object termed harmonic Poisson process: a Poisson process, over the positive half-line, with a harmonic intensity. The paper reviews the harmonic Poisson process, investigates its properties, and presents the connections of this object to an assortment of topics: uniform statistics, scale invariance, random multiplicative perturbations, Pareto and inverse-Pareto statistics, exponential growth and exponential decay, power-law renormalization, convergence and domains of attraction, the Langevin equation, diffusions, Benford’s law, and 1/f noise. - Highlights: • Harmonic statistics are described and reviewed in detail. • Connections to various statistical laws are established. • Connections to perturbation, renormalization and dynamics are established.

    A greater number of toxicity data are becoming publicly available allowing for in silico modeling. However, questions often arise as to how to incorporate data quality and how to deal with contradicting data if more than a single datum point is available for the same compound. In this study, two well-known and studied QSAR/QSPR models for skin permeability and aquatic toxicology have been investigated in the context of statistical data quality. In particular, the potential benefits of the incorporation of the statistical Confidence Scoring (CS) approach within modeling and validation. As a result, robust QSAR/QSPR models for the skin permeability coefficient and the toxicity of nonpolar narcotics to Aliivibrio fischeri assay were created. CS-weighted linear regression for training and CS-weighted root-mean-square error (RMSE) for validation were statistically superior compared to standard linear regression and standard RMSE. Strategies are proposed as to how to interpret data with high and low CS, as well as how to deal with large data sets containing multiple entries.

Retirement of the Space Shuttle Program and recent perturbations of NASA's Constellation Program will exacerbate this downward trend. Therefore it is crucial that ATP periodically revisit and determine which of its test capabilities are strategically important, which qualify as low-risk redundancies that could be put in an inactive status or closed, and address the challenges associated with both sustainment and improvements to the test capabilities that must remain active. This presentation will provide an overview of the ATP vision, mission, and goals as well as the challenges and opportunities the program is facing both today and in the future. We will discuss the strategy ATP is taking over the next five years to address the National aeronautics test capability challenges and what the program will do to capitalize on its opportunities to ensure a ready, robust and relevant portfolio of National aeronautics test capabilities.

    To identify the patterns of São Paulo state municipalities, in Brazil, regarding the relationship between tuberculosis and indicators of health care services, health care service availability, context, and social inequality. This ecological study covered all 645 municipalities of São Paulo and eight variables belonging to three dimensions: health care service availability, context, and social inequality. Data were analyzed using hierarchical and non-hierarchical clustering, principal components analysis, and geoprocessing. The analysis revealed five groups of municipalities: group 1 (117 municipalities), with similar directly observed treatment (DOT) and family health strategy (FHS) coverage, high tuberculosis incidence and death coefficients, and a low human development index (HDI); group 2 (142 municipalities), with low DOT and FHS coverage; group 3 (36 municipalities), with medium DOT and FHS coverage and high tuberculosis incidence, high demand for anti-HIV testing, and treatment dropout; group 4 (186 municipalities) with lower HDI as compared to groups 2, 3, and 5, but high FHS coverage and the lowest numbers of anti-HIV testing, tuberculosis incidence, and DOT coverage; and group 5 (164 municipalities), with better social conditions as compared to the other groups, medium FHS coverage, and higher DOT coverage. Together, the first two components selected for the study-health service availability in terms of DOT coverage indicator and social inequality indicator-explained 76.96% of the variance. In municipalities with high DOT coverage there was evidence of better organized tuberculosis control services. Municipalities with the highest social inequality had FHS coverage. However, without DOT, FHS seem less efficient to control tuberculosis.

    With the diversification and internationalization of the food industry and the increased focus on health from a majority of consumers, food safety policies are being implemented based on scientific evidence. Risk analysis represents the most useful scientific approach for making food safety decisions. Total diet study (TDS) is often used as a risk assessment tool to evaluate exposure to hazardous elements. Many countries perform TDSs to screen for chemicals in foods and analyze exposure trends to hazardous elements. TDSs differ from traditional food monitoring in two major aspects: chemicals are analyzed in food in the form in which it will be consumed and it is cost-effective in analyzing composite samples after processing multiple ingredients together. In Korea, TDSs have been conducted to estimate dietary intakes of heavy metals, pesticides, mycotoxins, persistent organic pollutants, and processing contaminants. TDSs need to be carried out periodically to ensure food safety.

    Serdobolskii, Vadim Ivanovich

    2007-01-01

    This monograph presents mathematical theory of statistical models described by the essentially large number of unknown parameters, comparable with sample size but can also be much larger. In this meaning, the proposed theory can be called "essentially multiparametric". It is developed on the basis of the Kolmogorov asymptotic approach in which sample size increases along with the number of unknown parameters.This theory opens a way for solution of central problems of multivariate statistics, which up until now have not been solved. Traditional statistical methods based on the idea of an infinite sampling often break down in the solution of real problems, and, dependent on data, can be inefficient, unstable and even not applicable. In this situation, practical statisticians are forced to use various heuristic methods in the hope the will find a satisfactory solution.Mathematical theory developed in this book presents a regular technique for implementing new, more efficient versions of statistical procedures. ...

    The Employee Benefit Research Institute (EBRI) maintains a wealth of data collected from various health savings account (HSA) providers. The EBRI HSA Database contains 2.9 million accounts with total assets of $5 billion as of Dec. 31, 2014. This Issue Brief is the second annual report drawing on cross-sectional data from the EBRI HSA Database. It examines account balances, individual and employer contributions, annual distributions, investment accounts, and account-owner demographics for 2014. Enrollment in HSA-eligible health plans is estimated to be about 17 million policyholders and their dependents, and it has also been estimated that there are 13.8 million accounts holding $24.2 billion in assets as of Dec. 31, 2014. Almost 4 in 5 HSAs have been opened since the beginning of 2011. The average HSA balance at the end of 2014 was $1,933, up from $1,408 at the beginning of the year. Average account balances increased with the age of the owner of the account. Account balances averaged $655 for owners under age 25 and $5,016 for owners ages 65 and older. About 6 percent of HSAs had an associated investment account. End-of-year 2014 balance averages were higher in accounts with investment assets. Thirty-seven percent of HSAs with investment assets ended 2014 with a balance of $10,000 or more, whereas only 4 percent of HSAs without investment assets had such a balance. Among HSAs with investment assets, accounts opened in 2014 ended the year with an average balance of $6,544; whereas those opened in 2005 had an average balance of $19,269 at the end of 2014. HSAs with either individual or employer contributions accounted for 70 percent of all accounts and 86 percent of the assets in 2014. Four percent of these accounts ended the year with a zero balance. On a yearly average, individuals who made contributions deposited $2,096 to their account. HSAs receiving employer contributions received $1,021 a year, on average. Four-fifths of HSAs with a contribution also had a

    Hilko van der Voet

    Full Text Available Nutrient recommendations in use today are often derived from relatively old data of few studies with few individuals. However, for many nutrients, including vitamin B-12, extensive data have now become available from both observational studies and randomized controlled trials, addressing the relation between intake and health-related status biomarkers. The purpose of this article is to provide new methodology for dietary planning based on dose-response data and meta-analysis. The methodology builds on existing work, and is consistent with current methodology and measurement error models for dietary assessment. The detailed purposes of this paper are twofold. Firstly, to define a Population Nutrient Level (PNL for dietary planning in groups. Secondly, to show how data from different sources can be combined in an extended meta-analysis of intake-status datasets for estimating PNL as well as other nutrient intake values, such as the Average Nutrient Requirement (ANR and the Individual Nutrient Level (INL. For this, a computational method is presented for comparing a bivariate lognormal distribution to a health criterion value. Procedures to meta-analyse available data in different ways are described. Example calculations on vitamin B-12 requirements were made for four models, assuming different ways of estimating the dose-response relation, and different values of the health criterion. Resulting estimates of ANRs and less so for INLs were found to be sensitive to model assumptions, whereas estimates of PNLs were much less sensitive to these assumptions as they were closer to the average nutrient intake in the available data.

    The current European standard (CES) and the World population age distribution standard is widely used in medical and demographic studies, performed by international (WHO, etc.) and national organizations. The Russian Federal Service of States Statistics (RosStat) uses CES in demographic yearbooks and other publications. The standard is applied in calculation of the standardized mortality rate (SMR) of the population in different countries and territories. Risk assessment is also used CES. In the basis of the standards there has been laid the idea to assess mortality according to uniform standard, so to get possibility to compare the mortality rate of the population in different countries and regions, different genders and different calendar years. Analysis of the results of test calculations of the values of the SMR for the population of Russia and other countries with the use of current standards has revealed serious shortcomings of the latters and set up the task of improving them. A new concept of the development of standards based on the use of the concept of stable equilibrium of the age distribution of the population and survivorship function is proposed.

    In the United Kingdom, air pollution is linked to around 40000 premature deaths each year, but estimating its health effects is challenging in a spatio-temporal study. The challenges include spatial misalignment between the pollution and disease data; uncertainty in the estimated pollution surface; and complex residual spatio-temporal autocorrelation in the disease data. This article develops a two-stage model that addresses these issues. The first stage is a spatio-temporal fusion model linking modeled and measured pollution data, while the second stage links these predictions to the disease data. The methodology is motivated by a new five-year study investigating the effects of multiple pollutants on respiratory hospitalizations in England between 2007 and 2011, using pollution and disease data relating to local and unitary authorities on a monthly time scale. © The Author 2016.

    The present study investigated the ionic and fluoride concentrations in tap water and its associated health risk to local dwellers of Ogun State (Abeokuta south), Nigeria. 63 samples were collected from twenty-one different locations. Results obtained revealed the mean concentration of fluoride (F - ) as 1.23 mg/L. Other water quality parameters such as total dissolved solids (TDS), electrical conductivity (EC), F - , Fe 2+, and SO 4 2- surpassed the WHO guidance for drinking water. Strong positive correlation was observed between F - and TDS; F - and pH; TDS and EC; TDS and Mg 2+ ; TDS and SO 4 2- ; TDS and HCO 3 - ; EC and HCO 3 - ; EC and SO 4 2- ; Na + and Cl - ; SO 4 2- and Cl - . In addition, Empirical Bayesian Kriging (EBK) model was employed to spatially distribute the concentration of the analyzed elements within the study region. The chronic daily dose (CDD) and hazard quotient (HQ) were also used to evaluate the health risk associated with F - , considering dermal and ingestion as pathways. The results revealed that the associated HQ for infants between the age range of 6-12months within about 91% of the study region surpassed the accepted HQ limit. However, the HQ for age categories 11-16years; >65years; 18-21years; 21years; 16-18years within 95.2%, 90.5%, 80.95% and 100% of the study location were less than 1. Conclusively, the HQ values obtained in this study should serve as a baseline information for water management authorities, policymakers and the society at large towards addressing these pollution issues.

    Understanding the dynamic behavior of complex structures such as long-span bridges requires dense deployment of sensors. Traditional wired sensor systems are generally expensive and time-consuming to install due to cabling. With wireless communication and on-board computation capabilities, wireless smart sensor networks have the advantages of being low cost, easy to deploy and maintain and therefore facilitate dense instrumentation for structural health monitoring. A long-term monitoring project was recently carried out for a cable-stayed bridge in South Korea with a dense array of 113 smart sensors, which feature the world's largest wireless smart sensor network for civil structural monitoring. This paper presents a comprehensive statistical analysis of the modal properties including natural frequencies, damping ratios and mode shapes of the monitored cable-stayed bridge. Data analyzed in this paper is composed of structural vibration signals monitored during a 12-month period under ambient excitations. The correlation between environmental temperature and the modal frequencies is also investigated. The results showed the long-term statistical structural behavior of the bridge, which serves as the basis for Bayesian statistical updating for the numerical model.

    Commercial, industrial, and research interests in the Arctic are expanding rapidly. Potentials are numerous and exciting, giving rise to the need for guidelines to ensure interactions among waterway users do not conflict. Of particular concern is the potential for adverse impacts to U.S. Arctic coastal communities that rely on living marine resources for nutritional and cultural health, through subsistence hunts from small craft, ice edges, and shore. Recent events raised concerns over research surveys potentially interfering with subsistence hunts in the Bering, Chukchi, and Beaufort Seas. Incidents led to calls by Native Alaskan communities to restrict science activities with a mixed response from the scientific community (i.e., some sympathetic, some defensive). With a common goal of wanting to mitigate this potential interaction, Federal agencies made a commitment in the National Strategy for the Arctic Region to coordinate and consult with Alaska Natives and also to pursue responsible Arctic stewardship, with understanding through scientific research and traditional knowledge. The effort to create a "Standard of Care" for research surveys incorporates years of experience by subsistence hunters working to mitigate impacts of other anthropogenic activities in the region, as well as best practices by many in the research community. The protocols are designed to ensure potential conflicts between the scientific research community and subsistence hunters are avoided and to encourage mutual assistance and collaboration between researchers and hunters. The guidelines focus on enhancing communication between researchers and subsistence hunters before, during, and after research occurs. The best management practices outlined in the Standard of Care assist those overseeing and funding scientific research in making decisions about how best to accomplish the goals of the research while ensuring protection of the Alaska subsistence lifestyle. These protocols could also be

    Long-term programs are necessary in order to minimize the medical consequences and to increase the efficiency of medical assistance to those who have undergone radiation action as a result of the Chernobyl catastrophe. It is also necessary to evaluate objectively the state of health of the sufferers, to obtain scientifically grounded conclusions on effects of 'low' radiation doses on human organism, and to estimate the genetic consequences for future generations. These programs must foresee the implementation of various activities, including: 1. Provision of further monitoring of persons attributed to the groups of risk, especially: those whose thyroid was irradiated when they were children and adolescents; children born by mothers whose thyroid was irradiated in their children-adolescent age; children whose thyroid was irradiated in pre-natal period; pregnant women; liquidators of 1986-1987 and their children born after 1986. 2. Provision of medical-prophylactic institutions on the polluted territories (of district and regional levels) and clinics of research centers with modern medico-diagnostic equipment, as well as regular supply of necessary reagents and medicines to hospitals and clinics. 3. Development of system of rehabilitation medical activities and sanatorium bases for the Chernobyl sufferers, especially for children. 4. Supply of food products with radioprotective properties; fresh vegetables, fruits etc., especially for children in the polluted territories. 5. Scientific study of radiation action combined with action of other carcinogens including chemical pollutants. (J.P.N.)

    Changes in the annual health examination records were investigated and classified by cause of death. In males with cancer, there was noted an increased incidence of abnormal hemoglobin amount, erythrocyte sedimentation rate, and traces of urinary proteins 1 year to 3 years before death. However, the incidence of urinary protein traces was low compared with that in other diseases. In males with cerebral vascular diseases, there was a high incidence of hypertension. Urinary protein traces appeared from 4 years to 5 years before death. In females with cardiovascular diseases including hypertensive diseases and valvular diseases, the incidence of urinary protein traces increased from 4 years to 5 years prior to their death. Erythrocyte sedimentation rate was generally high in these cases. In males with liver cirrhosis, urinary urobilinogen amount was generally more than that in other diseases. This tendency also appeared in females with liver cirrhosis 6 years before death. The incidence of abnormal hemoglobin amount and erythrocyte sedimentation rate was high in males with liver cirrhosis, and that of abnormal erythrocyte sedimentation rate was high in females with liver corrhosis.

    Introduction In 2012, the Louisiana (LA) Department of Health and Hospitals revised the LA birth certificate to include medical reasons for births before 39 completed weeks' gestation. We compared the completeness and validity of these data with hospital discharge records. Methods For births occurring 4/1/2012-9/30/2012 at Woman's Hospital of Baton Rouge, we linked maternal delivery and newborn birth data collected through the National Perinatal Information Center with LA birth certificates. Among early term births (37-38 completed weeks' gestation), we quantified the reasons for early delivery listed on the birth certificate and compared them with ICD-9-CM codes from Woman's discharge data. Results Among 4353 birth certificates indicating delivery at Woman's Hospital, we matched 99.8% to corresponding Woman's administrative data. Among 1293 early term singleton births, the most common reasons for early delivery listed on the birth certificate were spontaneous active labor (57.5%), gestational hypertensive disorders (15.3%), gestational diabetes (8.7%), and premature rupture of membranes (8.1%). Only 2.7% of births indicated "other reason" as the only reason for early delivery. Most reasons for early delivery had >80% correspondence with ICD-9-CM codes. Lower correspondence (35 and 72%, respectively) was observed for premature rupture of membranes and abnormal heart rate or fetal distress. Discussion There was near-perfect ability to match LA birth certificates with Woman's Hospital records, and the agreement between reasons for early delivery on the birth certificate and ICD-9-CM codes was high. A benchmark of 2.7% can be used as an attainable frequency of "other reason" for early delivery reported by hospitals. Louisiana implemented an effective mechanism to identify and explain early deliveries using vital records.

    The increasing presence of toxic chemicals released in the subsurface has led to a rapid growth of social concerns and the need to develop and employ models that can predict the impact of groundwater contamination on human health risk under uncertainty. Monitored natural attenuation is a common remediation action in many contamination cases. However, natural attenuation can lead to the production of daughter species of distinct toxicity that may pose challenges in pollution management strategies. The actual threat that these contaminants pose to human health depends on the interplay between the complex structure of the geological media and the toxicity of each pollutant byproduct. This work addresses human health risk for chemical mixtures resulting from the sequential degradation of a contaminant (such as a chlorinated solvent) under uncertainty through high-resolution three-dimensional numerical simulations. We systematically investigate the interaction between aquifer heterogeneity, flow connectivity, contaminant injection model, and chemical toxicity in the probabilistic characterization of health risk. We illustrate how chemical-specific travel times control the regime of the expected risk and its corresponding uncertainties. Results indicate conditions where preferential flow paths can favor the reduction of the overall risk of the chemical mixture. The overall human risk response to aquifer connectivity is shown to be nontrivial for multispecies transport. This nontriviality is a result of the interaction between aquifer heterogeneity and chemical toxicity. To quantify the joint effect of connectivity and toxicity in health risk, we propose a toxicity-based Damköhler number. Furthermore, we provide a statistical characterization in terms of low-order moments and the probability density function of the individual and total risks.

    Brain opioid peptide systems are known to play an important role in motivation, emotion, attachment behaviour, the response to stress and pain, and the control of food intake. Opioid peptides within the ventral striatum are thought to play a key role in the latter function, regulating the affective response to highly palatable, energy-dense foods such as those containing fat and sugar. It has been shown previously that stimulation of mu opiate receptors within the ventral striatum increases intake of palatable food. In the present study, we examined enkephalin peptide gene expression within the striatum in rats that had been given restricted daily access to an energy-dense, palatable liquid food, chocolate Ensure(R). Rats maintained on an ad libitum diet of rat chow and water were given 3-h access to Ensure(R) daily for two weeks. One day following the end of this period, preproenkephalin gene expression was measured with quantitative in situ hybridization. Compared with control animals, rats that had been exposed to Ensure(R) had significantly reduced enkephalin gene expression in several striatal regions including the ventral striatum (nucleus accumbens), a finding that was confirmed in a different group with Northern blot analysis. Rats fed this regimen of Ensure(R) did not differ in weight from controls. In contrast to chronic Ensure(R), acute ingestion of Ensure(R) did not appear to affect enkephalin peptide gene expression. These results suggest that repeated consumption of a highly rewarding, energy-dense food induces neuroadaptations in cognitive-motivational circuits.

    Both the natural and social science data communities are attempting to address the long-term sustainability of their data infrastructures in rapidly changing research, technological, and policy environments. Many parts of these communities are also considering how to improve the interoperability and integration of their data and systems across natural, social, health, and other domains. However, these efforts have generally been undertaken in parallel, with little thought about how different sustainability approaches may impact long-term interoperability from scientific, legal, or economic perspectives, or vice versa, i.e., how improved interoperability could enhance—or threaten—infrastructure sustainability. Scientific progress depends substantially on the ability to learn from the legacy of previous work available for current and future scientists to study, often by integrating disparate data not previously assembled. Digital data are less likely than scientific publications to be usable in the future unless they are managed by science-oriented repositories that can support long-term data access with the documentation and services needed for future interoperability. We summarize recent discussions in the social and natural science communities on emerging approaches to sustainability and relevant interoperability activities, including efforts by the Belmont Forum E-Infrastructures project to address global change data infrastructure needs; the Group on Earth Observations to further implement data sharing and improve data management across diverse societal benefit areas; and the Research Data Alliance to develop legal interoperability principles and guidelines and to address challenges faced by domain repositories. We also examine emerging needs for data interoperability in the context of the post-2015 development agenda and the expected set of Sustainable Development Goals (SDGs), which set ambitious targets for sustainable development, poverty reduction, and

    The method of least squares is probably the most powerful data analysis tool available to scientists. Toward a fuller appreciation of that power, this work begins with an elementary review of statistics fundamentals, and then progressively increases in sophistication as the coverage is extended to the theory and practice of linear and nonlinear least squares. The results are illustrated in application to data analysis problems important in the life sciences. The review of fundamentals includes the role of sampling and its connection to probability distributions, the Central Limit Theorem, and the importance of finite variance. Linear least squares are presented using matrix notation, and the significance of the key probability distributions-Gaussian, chi-square, and t-is illustrated with Monte Carlo calculations. The meaning of correlation is discussed, including its role in the propagation of error. When the data themselves are correlated, special methods are needed for the fitting, as they are also when fitting with constraints. Nonlinear fitting gives rise to nonnormal parameter distributions, but the 10% Rule of Thumb suggests that such problems will be insignificant when the parameter is sufficiently well determined. Illustrations include calibration with linear and nonlinear response functions, the dangers inherent in fitting inverted data (e.g., Lineweaver-Burk equation), an analysis of the reliability of the van't Hoff analysis, the problem of correlated data in the Guggenheim method, and the optimization of isothermal titration calorimetry procedures using the variance-covariance matrix for experiment design. The work concludes with illustrations on assessing and presenting results.

    Ontario, the most populous province in Canada, has a universal healthcare system that routinely collects health administrative data on its 13 million legal residents that is used for health research. Record linkage has become a vital tool for this research by enriching this data with the Immigration, Refugees and Citizenship Canada Permanent Resident (IRCC-PR) database and the Office of the Registrar General's Vital Statistics-Death (ORG-VSD) registry. Our objectives were to estimate linkage rates and compare characteristics of individuals in the linked versus unlinked files. We used both deterministic and probabilistic linkage methods to link the IRCC-PR database (1985-2012) and ORG-VSD registry (1990-2012) to the Ontario's Registered Persons Database. Linkage rates were estimated and standardized differences were used to assess differences in socio-demographic and other characteristics between the linked and unlinked records. The overall linkage rates for the IRCC-PR database and ORG-VSD registry were 86.4 and 96.2 %, respectively. The majority (68.2 %) of the record linkages in IRCC-PR were achieved after three deterministic passes, 18.2 % were linked probabilistically, and 13.6 % were unlinked. Similarly the majority (79.8 %) of the record linkages in the ORG-VSD were linked using deterministic record linkage, 16.3 % were linked after probabilistic and manual review, and 3.9 % were unlinked. Unlinked and linked files were similar for most characteristics, such as age and marital status for IRCC-PR and sex and most causes of death for ORG-VSD. However, lower linkage rates were observed among people born in East Asia (78 %) in the IRCC-PR database and certain causes of death in the ORG-VSD registry, namely perinatal conditions (61.3 %) and congenital anomalies (81.3 %). The linkages of immigration and vital statistics data to existing population-based healthcare data in Ontario, Canada will enable many novel cross-sectional and longitudinal studies to

    Full Text Available Abstract Background This research concerns Araucanía, often called the Ninth Region, the poorest region of Chile where inequalities are most extreme. Araucanía hasn't enjoyed the economic success Chile achieved when the country returned to democracy in 1990. The Ninth Region also has the largest ethnic Mapuche population, located in rural areas and attached to small agricultural properties. Written and oral histories of diseases have been the most frequently used methods to explore the links between an ancestral population's perception of health conditions and their deprived environments. With census data and hospital records, it is now possible to incorporate statistical data about the links between poverty and disease among ethnic communities and compare results with non-Mapuche population. Data sources Hospital discharge records from Health Services North N = 24,126 patients, year 2003, and 7 hospitals, Health Services South (N = 81,780 patients and 25 hospitals; CAS-2/Family records (N = 527,539 individuals, 439 neighborhoods, 32 Comunas. Methods Given the over-dispersion of data and the clustered nature of observations, we used the global Moran's I and General G Gettis-Ord procedures to test spatial dependence. These tests confirmed the clusters of disease and the need to use spatial regression within a General Linear Mixed Model perspective. Results Health outcomes indicate significantly higher morbidity rates for the Mapuche compared to non-Mapuche in both age groups Mapuches than non-Mapuches for the entire Ninth Region and for all age groups. Mortality caused by respiratory infections is higher among Mapuches than non-Mapuches in all age-groups. A major finding is the link between poverty and respiratory infections. Conclusion Poverty is significantly associated with respiratory infections in the population of Chile's Ninth Region. High deprivation areas are associated with poverty, and poverty is a predictor of respiratory infections

Araucanía hasn't enjoyed the economic success Chile achieved when the country returned to democracy in 1990. The Ninth Region also has the largest ethnic Mapuche population, located in rural areas and attached to small agricultural properties. Written and oral histories of diseases have been the most frequently used methods to explore the links between an ancestral population's perception of health conditions and their deprived environments. With census data and hospital records, it is now possible to incorporate statistical data about the links between poverty and disease among ethnic communities and compare results with non-Mapuche population. Hospital discharge records from Health Services North N = 24,126 patients, year 2003, and 7 hospitals), Health Services South (N = 81,780 patients and 25 hospitals); CAS-2/Family records (N = 527,539 individuals, 439 neighborhoods, 32 Comunas). Given the over-dispersion of data and the clustered nature of observations, we used the global Moran's I and General G Gettis-Ord procedures to test spatial dependence. These tests confirmed the clusters of disease and the need to use spatial regression within a General Linear Mixed Model perspective. Health outcomes indicate significantly higher morbidity rates for the Mapuche compared to non-Mapuche in both age groups Mapuches than non-Mapuches for the entire Ninth Region and for all age groups. Mortality caused by respiratory infections is higher among Mapuches than non-Mapuches in all age-groups. A major finding is the link between poverty and respiratory infections. Poverty is significantly associated with respiratory infections in the population of Chile's Ninth Region. High deprivation areas are associated with poverty, and poverty is a predictor of respiratory infections. Mapuches are at higher risk of deaths caused by respiratory infections in

    Technology has had an unquestionable impact on the way people watch sports. Along with this technological evolution has come a higher standard to ensure a good viewing experience for the casual sports fan. It can be argued that the pervasion of statistical analysis in sports serves to satiate the fan's desire for detailed sports statistics. The goal of statistical analysis in sports is a simple one: to eliminate subjective analysis. In this paper, we review previous work that attempts to anal...

    INTRODUCTION: Telemedicine is often seen as the solution to the challenge of providing health care for an increasing number of people with chronic conditions. Projects are often organised locally and based on the involvement of stakeholders with a wide range of backgrounds. It can be challenging...... to ensure that projects are based on previous experience and that they do not repeat previous studies. To better understand these challenges and current practice, we examined telemedicine projects funded in the 2008-2010 period to explore where, how and to what extent results from the projects were....... The investigators should ensure proper documentation and dissemination of changes both during and after the projects in order to ensure transparency, and national or international organisations should establish a database with relevant data fields.

    2016-06-01

    Full Text Available The purpose of the present study is to define, based on a theoretical identification, the significance of production diversification in ensuring financial security of agricultural farms and a presentation of the specificity of multi-directional  farms in Poland. The entities included in the research were the ones conducting agricultural activity of a mixed type: mixed cropping and mixed crops-livestock in the years 2007-2013. The analysis was carried out based on data obtained from the statistical publications of the Central Statistical Office. On the basis of an analysis of the structure and dynamics.   The size of utilised agriculturally area and their use, economicsize, the type and structure of plantation as well as the species and number of farm animals were all taken into consideration in the analysis. Based on the theoretical considerations presented it is evident that production diversification plays an important role in the reduction of the agricultural activity risk, and thus it contributes to maintaining stability and thereby preserving the financial security of farms. The results of empirical research prove that those farms that diversify their production are mainly farms of small economic size, producing for their own use. Diversification acts as a safety buffer in the case of these farms. It ensures self-sufficiency in terms of consumption and fodder production as well as small income. In the case of farms with bigger UAA it ensures proper functioning and survival on the market.

    Full Text Available This paper assessed factors that influence the internal controls in ensuring good corporate governance in financial institutions in developing economies with special reference to Zimbabwe. The research paper assessed how lack of internal controls affected good corporate governance and aimed to bring out elements of good corporate governance. It emerged that failure to effectively implement internal controls contributed significantly to poor corporate governance. The study discovered that internal control system overrides and the issue of “fact cat” directors also contributed to poor corporate governance. The study recommended that there is need for the board of directors to guarantee an organizational structure that clearly defines management responsibilities, authority and reporting relationships. There is also need to ensure that delegated responsibilities are effectively carried out to ensure compliance with internal controls of the financial institution concerned.

    The anatomical shape of bones and joints is important for their proper function but quantifying this, and detecting pathological variations, is difficult to do. Numerical descriptions would also enable correlations between joint shapes to be explored. Statistical shape modelling (SSM) is a method of image analysis employing pattern recognition statistics to describe and quantify such shapes from images; it uses principal components analysis to generate modes of variation describing each image in terms of a set of numerical scores after removing global size variation. We used SSM to quantify the shapes of the hip and the lumbar spine in dual-energy x-ray absorptiometry (DXA) images from 1511 individuals in the MRC National Survey of Health and Development at ages 60-64 years. We compared shapes of both joints in men and women and hypothesised that hip and spine shape would be strongly correlated. We also investigated associations with height, weight, body mass index (BMI) and local (hip or lumber spine) bone mineral density. In the hip, all except one of the first 10 modes differed between men and women. Men had a wider femoral neck, smaller neck-shaft angle, increased presence of osteophytes and a loss of the femoral head/neck curvature compared with women. Women presented with a flattening of the femoral head and greater acetabular coverage of the femoral head. Greater weight was associated with a shorter, wider femoral neck and larger greater and lesser trochanters. Taller height was accompanied by a flattening of the curve between superior head and neck and a larger lesser trochanter. Four of the first eight modes describing lumbar spine shape differed between men and women. Women tended to have a more lordotic spine than men with relatively smaller but caudally increasing anterior-posterior (a-p) vertebral diameters. Men were more likely to have a straighter spine with larger vertebral a-p diameters relative to vertebral height than women, increasing cranially

    2017-10-01

    This retrospective study used medical records from The Health Improvement Network (THIN) and Hospital Episode Statistics (HES) database to evaluate endometriosis (incidence, treatment and need for recurrent invasive procedures) in the general UK population. Women aged 12-54 years between January 2000 and December 2010, with a Read code for endometriosis, were identified in THIN. Cases were validated by manual review of free-text comments in medical records and responses to physician questionnaires. False-negative cases were identified among women with Read codes for hysterectomy or dysmenorrhea. Prescriptions of medical therapies for endometriosis were identified in THIN. Cases of single and recurrent invasive procedures were identified in women with medical records in both THIN and HES. Overall, 5087 women had a Read code for endometriosis, corresponding to an incidence of 1.02 (95% confidence interval [CI]: 0.99-1.05) per 1000 person-years. After case validation, the estimate was 1.46 (95% CI: 1.43-1.50) per 1000 person-years. Medical therapy was prescribed to 55.5% of women with endometriosis in the first year after diagnosis. In total, 48.3% of women received invasive treatment during the study period; approximately one-fifth of these women required further invasive treatment, mainly in the 3 years after the index procedure. Using Read codes as the only method to identify women with endometriosis underestimates incidence. Over half of women with recorded endometriosis are prescribed medical therapy in the first year after diagnosis. Women with diagnosed endometriosis are at risk of requiring recurrent invasive procedures.

    A major obstacle in ensuring ubiquitous information is the utilization of heterogeneous systems in eHealth. The objective in this paper is to illustrate how an architecture for distributed eHealth databases can be designed without lacking the characteristic features of traditional sustainable databases. The approach is firstly to explain traditional architecture in central and homogeneous distributed database computing, followed by a possible approach to use an architectural framework to obtain sustainability across disparate systems i.e. heterogeneous databases, concluded with a discussion. It is seen that through a method of using relaxed ACID properties on a service-oriented architecture it is possible to achieve data consistency which is essential when ensuring sustainable interoperability.

  1. Global Uranium Supply Ensured for Long Term, New Report Shows

    International Nuclear Information System (INIS)

    2012-01-01

    Full text: Uranium resources and production are on the rise with the security of uranium supply ensured for the long term, according to a new report by the OECD Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA). Uranium 2011: Resources, Production and Demand, commonly referred to as the ''Red Book'', shows that total identified uranium resources have grown 12.5% since 2008. However, the costs of production have also increased, leading to reductions in lower cost category resources. These figures, which reflect the situation as of 1 January 2011, mean that total identified resources are sufficient for over 100 years of supply based on current requirements. Global uranium mine production increased by over 25% between 2008 and 2010 because of significantly increased production in Kazakhstan, currently the world's leading producer. The increased resource base has been achieved thanks to a 22% increase in uranium exploration and mine development expenditures between 2008 and 2010, which in 2010 totalled over $2 billion. Demand for uranium is expected to continue to rise for the foreseeable future. Although the Fukushima Daiichi nuclear accident has affected nuclear power projects and policies in some countries, nuclear power remains a key part of the global energy mix. Several governments have plans for new nuclear power plant construction, with the strongest expansion expected in China, India, the Republic of Korea and the Russian Federation. The speed and magnitude of growth in generating capacity elsewhere is still to be determined. By the year 2035, according to the joint NEA-IAEA Secretariat, world nuclear electricity generating capacity is projected to grow from 375 GWe net (at the end of 2010) to between 540 GWe net in the low demand case and 746 GWe net in the high demand case, increases of 44% and 99% respectively. Accordingly, world annual reactor-related uranium requirements are projected to rise from 63 875 tonnes of uranium metal

    Full Text Available With the rapid growth of network technologies, users are used to accessing various services with their mobile devices. To ensure security and privacy in mobility networks, proper mechanisms to authenticate the mobile user are essential. In this paper, a mobility network authentication scheme based on elliptic curve cryptography is proposed. In the proposed scheme, a mobile user can be authenticated without revealing who he is for user anonymity, and a session key is also negotiated to protect the following communications. The proposed mobility network authentication scheme is analyzed to show that it can ensure security, user anonymity, and convenience. Moreover, Burrows-Abadi-Needham logic (BAN logic is used to deduce the completeness of the proposed authentication scheme.

  4. A Safety Ensuring Mechanism for Holonic Manufacturing Systems

    Science.gov (United States)

    Tamura, Shinsuke; Yanase, Tatsuro; Nishi, Naoya

    This paper discusses a mechanism to ensure safe behaviors of HMSs (Holonic Manufacturing Systems). The change from low-variety high-volume to high-variety low-volume production requires highly flexible and adaptive manufacturing systems. Multi agent systems, in which decisions are made through cooperation among autonomous and cooperative elements, fulfill these requirements by exploiting full abilities of individual elements while eliminating various bottlenecks that exist in conventional systems. However, highly adaptive features induce non-deterministic behaviors of systems, and make it difficult to adopt multi agent systems as primary bases of manufacturing systems. In order to apply these systems to large and complicated applications, mechanisms that make their behaviors more predictable are essential. HMSs are a kind of multi agent systems, and an HMS safety ensuring mechanism proposed here is one of the attempts to make behaviors of multi agent systems more predictable.

    2018-01-01

    Progress in science is dependent on a strong foundation of reliable results. The publish or perish paradigm in research, coupled with an increase in retracted articles from the peer-reviewed literature, is beginning to erode the trust of both the scientific community and the public. The NIH is combating errors by requiring investigators to follow new guidelines addressing scientific premise, experimental design, biological variables, and authentication of reagents. Herein, we discuss how implementation of NIH guidelines will help investigators proactively address pitfalls of experimental design and methods. Careful consideration of the variables contributing to reproducibility helps ensure robust results.

    Johnson, Kain; Sully, Andrew; Anthenat, Bruce

    2014-01-01

    The safety and effectiveness of customized formulations have always been priorities for compounding pharmacists, perhaps even more so since a tragic outbreak of meningitis in 2012 was traced to preparations from the New England Compounding Center in Framingham, Massachusetts. Since that time, pharmaceutical compounding in the U.S. has been the focus of renewed interest from the public and from government organizations and regulatory bodies created to ensure patient safety. As a result, responsible compounders have responded to ensure--to even greater levels--the purity and safety of the formulations they prepare. One tool useful in doing so is the mechanical vial washer, which can produce cleaner vials (and/or ampules, syringes, and cartridges, depending on the washer model) more consistently than does washing vessels by hand. In this article, several such washers appropriate for use in a compounding pharmacy are profiled, and a pharmacist's experience in using one of those models is described.

    The use of qualitative research methodology is well established for data generation within healthcare research generally and clinical pharmacy research specifically. In the past, qualitative research methodology has been criticized for lacking rigour, transparency, justification of data collection and analysis methods being used, and hence the integrity of findings. Demonstrating rigour in qualitative studies is essential so that the research findings have the "integrity" to make an impact on practice, policy or both. Unlike other healthcare disciplines, the issue of "quality" of qualitative research has not been discussed much in the clinical pharmacy discipline. The aim of this paper is to highlight the importance of rigour in qualitative research, present different philosophical standpoints on the issue of quality in qualitative research and to discuss briefly strategies to ensure rigour in qualitative research. Finally, a mini review of recent research is presented to illustrate the strategies reported by clinical pharmacy researchers to ensure rigour in their qualitative research studies.

    Full Text Available Informal educational programs that reach out to minority youth in low-income urban areas need to anticipate diversity. Not only will participants exhibit a range of abilities and needs, but some, just like in any population, are likely to have learning disabilities. ScienceQuest, an informal science education program funded by the National Science Foundation, was designed to ensure that youth aged 10 to 14 with diverse abilities and needs, including learning disabilities, can successfully participate and succeed in inquiry-based learning. The program uses the I-Search curriculum as the basis of its inquiry process. Embedded in this curriculum are the following inclusive practices: youth are motivated to explore their topic; they use varied media that supports their learning styles; they are guided to process information through multiple means; and they have access to technology tools. These ongoing inclusive practices ensure that everyone successfully explores the world around them.

    With putting in operation the first digital TELEPERM XS I and C systems for functions important to safety in nuclear power plants, ensuring long-term availability and reliable operation of TELEPERM XS systems gains increasing importance. On the one hand, the modular structure of TELEPERM XS has already been optimized during system development such that the application-specific functions are independent of the version of hardware components and system software. On the other hand, hardware-independent, tool-based engineering procedures ensure that the application software of installed I and C systems can be flexibly adapted to modified plant requirements while at the same time the very high software quality is retained. Quality-assured procedures and an actively organized configuration management guarantee that the functionality and the availability of the I and C systems keep their qualified standard. This paper discusses aspects of the configuration management for TELEPERM XS I and C systems. (author)

  11. KEY ASPECTS OF ENSURING ENERGY EFFICIENCY OF BUILDINGS AND STRUCTURES

    2017-06-01

    Full Text Available The paper is based on the review of the foreign and national academic literature and intended to emphasize the issues of ensuring energy efficiency of buildings and structures applicable to all the countries as for reconstruction of existing buildings as for erection of new ones . The author highlights the key aspects of the provision of energy efficiency of buildings and structures in some foreign countries. The conclusion is made that the studies are mainly aimed at discovering new heat insulation materials, whereby polystyrene insulation is found to be the most widespread wall insulation material in a number of countries. At the same time, it is observed that the ongoing research is focused on solutions to optimize the structure of walling systems in terms of both insulant thickness and the number and sequence of insulation layers in the walling structure. A conclusion is made that hyper insulation of external walls leads to considerable expenses arising due to cooling during the summer season. The use of prefabricated vacuum panels as a heat insulation layer and off-the-shelf single-layer structures, subject to their heat insulation characteristics, appears a more constructive way to meet the energy efficiency requirements, as the arrangement of ideal air space in multilayered walls proves a significant challenge today. One of the most promising ways to ensure energy efficiency is the use of multifunctional polyvalent walls and provision of polyvalent heat supply from renewable energy sources. Since energy efficiency depends on the spatial arrangement of buildings, construction must ensure a minimum ratio of the area of enclosing structures to the overall building volume (by adding on new facilities in case of reconstruction. It is noted that a systemic approach to ensuring energy efficiency of buildings is impossible without proper regard to the environmental parameters of heat insulation materials.

  16. Cep63 and cep152 cooperate to ensure centriole duplication.

    Directory of Open Access Journals (Sweden)

    Nicola J Brown

    Full Text Available Centrosomes consist of two centrioles embedded in pericentriolar material and function as the main microtubule organising centres in dividing animal cells. They ensure proper formation and orientation of the mitotic spindle and are therefore essential for the maintenance of genome stability. Centrosome function is crucial during embryonic development, highlighted by the discovery of mutations in genes encoding centrosome or spindle pole proteins that cause autosomal recessive primary microcephaly, including Cep63 and Cep152. In this study we show that Cep63 functions to ensure that centriole duplication occurs reliably in dividing mammalian cells. We show that the interaction between Cep63 and Cep152 can occur independently of centrosome localisation and that the two proteins are dependent on one another for centrosomal localisation. Further, both mouse and human Cep63 and Cep152 cooperate to ensure efficient centriole duplication by promoting the accumulation of essential centriole duplication factors upstream of SAS-6 recruitment and procentriole formation. These observations describe the requirement for Cep63 in maintaining centriole number in dividing mammalian cells and further establish the order of events in centriole formation.

    Full Text Available The article considers evolution of development of the paradigm of ensuring competitive advantages of an enterprise. Foreign and domestic scientists focus on individual directions of development of competitive advantages and pay insufficient attention to new management concepts – development of the information society, knowledge economy and dynamism of integration processes. The goal of the study is formation of the modern paradigm of ensuring competitive advantages of an enterprise with consideration of tendencies of development of the knowledge economy, information society and integration processes. Enterprise competitiveness is a synergetic characteristic, which reflects enterprise capability of dynamic response to changes of the market situation with the aim of keeping predominance over other economic subjects. Management of the future, on the basis of the management 2.0 concept, should take into account interests not only of top management and shareholders but also employees, local communities and territories and meet requirements of the society in general, individual groups of consumers and tendencies of development of managerial and information technologies. The paradigm of the modern theory of ensuring competitive advantages should include models of keeping competitive advantages in the existing markets and models of development of future markets; strategy of development of enterprise competitiveness, human capital development and efficient enterprise management.

    Medical facility statistics provide essential information to policymakers, administrators, academics, and practitioners in the field of health services. In Japan, the Health Statistics Office of the Director-General for Statistics and Information Policy at the Ministry of Health, Labour and Welfare is generating these statistics. Although the statistics are widely available in both Japanese and English, the methodology described in the technical reports are primarily in Japanese, and are not fully described in English. This article aimed to describe these processes for readers in the English-speaking world. The Health Statistics Office routinely conduct two surveys called the Hospital Report and the Survey of Medical Institutions. The subjects of the former are all the hospitals and clinics with long-term care beds in Japan. It comprises a Patient Questionnaire focusing on the numbers of inpatients, admissions, discharges, and outpatients in one month, and an Employee Questionnaire, which asks about the number of employees as of October 1. The Survey of Medical Institutions consists of the Dynamic Survey, which focuses on the opening and closing of facilities every month, and the Static Survey, which focuses on staff, facilities, and services as of October 1, as well as the number of inpatients as of September 30 and the total number of outpatients during September. All hospitals, clinics, and dental clinics are requested to submit the Static Survey questionnaire every three years. These surveys are useful tools for collecting essential information, as well as providing occasions to implicitly inform facilities of the movements of government policy.

    Full Text Available This study focuses on strategies and statistical considerations for assessment of translation in language (e.g. translation of case report forms in multinational clinical trials, information (e.g. translation of basic discoveries to the clinic and technology (e.g. translation of Chinese diagnostic techniques to well-established clinical study endpoints in pharmaceutical/clinical research and development. However, most of our efforts will be directed to statistical considerations for translation in information. Translational medicine has been defined as bench-to-bedside research, where a basic laboratory discovery becomes applicable to the diagnosis, treatment or prevention of a specific disease, and is brought forth by either a physician—scientist who works at the interface between the research laboratory and patient care, or by a team of basic and clinical science investigators. Statistics plays an important role in translational medicine to ensure that the translational process is accurate and reliable with certain statistical assurance. Statistical inference for the applicability of an animal model to a human model is also discussed. Strategies for selection of clinical study endpoints (e.g. absolute changes, relative changes, or responder-defined, based on either absolute or relative change are reviewed.

  5. Sample Size and Statistical Conclusions from Tests of Fit to the Rasch Model According to the Rasch Unidimensional Measurement Model (Rumm) Program in Health Outcome Measurement.

    Science.gov (United States)

    Hagell, Peter; Westergren, Albert

    Sample size is a major factor in statistical null hypothesis testing, which is the basis for many approaches to testing Rasch model fit. Few sample size recommendations for testing fit to the Rasch model concern the Rasch Unidimensional Measurement Models (RUMM) software, which features chi-square and ANOVA/F-ratio based fit statistics, including Bonferroni and algebraic sample size adjustments. This paper explores the occurrence of Type I errors with RUMM fit statistics, and the effects of algebraic sample size adjustments. Data with simulated Rasch model fitting 25-item dichotomous scales and sample sizes ranging from N = 50 to N = 2500 were analysed with and without algebraically adjusted sample sizes. Results suggest the occurrence of Type I errors with N less then or equal to 500, and that Bonferroni correction as well as downward algebraic sample size adjustment are useful to avoid such errors, whereas upward adjustment of smaller samples falsely signal misfit. Our observations suggest that sample sizes around N = 250 to N = 500 may provide a good balance for the statistical interpretation of the RUMM fit statistics studied here with respect to Type I errors and under the assumption of Rasch model fit within the examined frame of reference (i.e., about 25 item parameters well targeted to the sample).

    2015-12-01

    This paper presents a viewpoint concerning the largely neglected clinical relevance of spirituality and religious belief in speech-language pathology (SLP) assessments, interventions and outcomes across the lifespan. An overview of the refereed SLP literature is presented with regard to religion and spirituality. It was found that while there is increasing research with regard to spirituality, health and well-being, there is very little specific to SLP. What is available and clinically relevant, generally relates to holistic care and/or cultural and linguistic diversity. Amidst the health care literature, however, there is a growing number of recommended instruments (for religious/spiritual screening) sensitive to intercultural and interfaith issues that are currently available to medical, nursing, allied health and chaplaincy practitioners. These instruments can also be of value to SLPs to ensure holistic assessments and interventions. It would seem timely for SLPs (and other allied health practitioners) to consider including spiritual screenings/assessments as part of their clinical practice so as to ensure appropriate holistic care. This would also mean undertaking research and including relevant education within tertiary institutions and professional development programs.

    To identify whether, by what means, and the extent to which historically, government health care expenditure growth in Europe has changed following economic crises. Organization for Economic Cooperation and Development Health Data 2011. Cross-country fixed effects multiple regression analysis is used to determine whether statutory health care expenditure growth in the year after economic crises differs from that which would otherwise be predicted by general economic trends. Better understanding of the mechanisms involved is achieved by distinguishing between policy responses which lead to cost-shifting and all others. In the year after an economic downturn, public health care expenditure grows more slowly than would have been expected given the longer term economic climate. Cost-shifting and other policy responses are both associated with these slowdowns. However, while changes in tax-derived expenditure are associated with both cost-shifting and other policy responses following a crisis, changes in expenditure derived from social insurance have been associated only with changes in cost-shifting. Disproportionate cuts to the health sector, as well as reliance on cost-shifting to slow growth in health care expenditure, serve as a warning in terms of potentially negative effects on equity, efficiency, and quality of health services and, potentially, health outcomes following economic crises. © Health Research and Educational Trust.

  18. Reflexion on linear regression trip production modelling method for ensuring good model quality

    2017-11-01

    Transport Modelling is important. For certain cases, the conventional model still has to be used, in which having a good trip production model is capital. A good model can only be obtained from a good sample. Two of the basic principles of a good sampling is having a sample capable to represent the population characteristics and capable to produce an acceptable error at a certain confidence level. It seems that this principle is not yet quite understood and used in trip production modeling. Therefore, investigating the Trip Production Modelling practice in Indonesia and try to formulate a better modeling method for ensuring the Model Quality is necessary. This research result is presented as follows. Statistics knows a method to calculate span of prediction value at a certain confidence level for linear regression, which is called Confidence Interval of Predicted Value. The common modeling practice uses R2 as the principal quality measure, the sampling practice varies and not always conform to the sampling principles. An experiment indicates that small sample is already capable to give excellent R2 value and sample composition can significantly change the model. Hence, good R2 value, in fact, does not always mean good model quality. These lead to three basic ideas for ensuring good model quality, i.e. reformulating quality measure, calculation procedure, and sampling method. A quality measure is defined as having a good R2 value and a good Confidence Interval of Predicted Value. Calculation procedure must incorporate statistical calculation method and appropriate statistical tests needed. A good sampling method must incorporate random well distributed stratified sampling with a certain minimum number of samples. These three ideas need to be more developed and tested.

  19. Breast cancer statistics, 2011.

    2011-01-01

    In this article, the American Cancer Society provides an overview of female breast cancer statistics in the United States, including trends in incidence, mortality, survival, and screening. Approximately 230,480 new cases of invasive breast cancer and 39,520 breast cancer deaths are expected to occur among US women in 2011. Breast cancer incidence rates were stable among all racial/ethnic groups from 2004 to 2008. Breast cancer death rates have been declining since the early 1990s for all women except American Indians/Alaska Natives, among whom rates have remained stable. Disparities in breast cancer death rates are evident by state, socioeconomic status, and race/ethnicity. While significant declines in mortality rates were observed for 36 states and the District of Columbia over the past 10 years, rates for 14 states remained level. Analyses by county-level poverty rates showed that the decrease in mortality rates began later and was slower among women residing in poor areas. As a result, the highest breast cancer death rates shifted from the affluent areas to the poor areas in the early 1990s. Screening rates continue to be lower in poor women compared with non-poor women, despite much progress in increasing mammography utilization. In 2008, 51.4% of poor women had undergone a screening mammogram in the past 2 years compared with 72.8% of non-poor women. Encouraging patients aged 40 years and older to have annual mammography and a clinical breast examination is the single most important step that clinicians can take to reduce suffering and death from breast cancer. Clinicians should also ensure that patients at high risk of breast cancer are identified and offered appropriate screening and follow-up. Continued progress in the control of breast cancer will require sustained and increased efforts to provide high-quality screening, diagnosis, and treatment to all segments of the population.

    2000-01-01

    Written by pioneers in this exciting new field, Algebraic Statistics introduces the application of polynomial algebra to experimental design, discrete probability, and statistics. It begins with an introduction to Gröbner bases and a thorough description of their applications to experimental design. A special chapter covers the binary case with new application to coherent systems in reliability and two level factorial designs. The work paves the way, in the last two chapters, for the application of computer algebra to discrete probability and statistical modelling through the important concept of an algebraic statistical model.As the first book on the subject, Algebraic Statistics presents many opportunities for spin-off research and applications and should become a landmark work welcomed by both the statistical community and its relatives in mathematics and computer science.

  9. Ensuring Data Consistency Over CMS Distributed Computing System

    CERN Document Server

    Rossman, Paul

    2009-01-01

    CMS utilizes a distributed infrastructure of computing centers to custodially store data, to provide organized processing resources, and to provide analysis computing resources for users. Integrated over the whole system, even in the first year of data taking, the available disk storage approaches 10 petabytes of space. Maintaining consistency between the data bookkeeping, the data transfer system, and physical storage is an interesting technical and operations challenge. In this paper we will discuss the CMS effort to ensure that data is consistently available at all computing centers. We will discuss the technical tools that monitor the consistency of the catalogs and the physical storage as well as the operations model used to find and solve inconsistencies.

    2013-08-01

    The ISO / Technical Committee 20 / Sub-committee 14 develops debris-related standards and technical reports to mitigate debris and help ensure mission and space sustainability. While UN Guidelines and the IADC Guidelines encourage national governments and agencies to promote debris mitigation design and operation, the ISO standards will help the global space industry promote and sustain its space-related business. In this paper the scope and status of each ISO standard is discussed within an overall framework. A comparison with international guidelines is also provided to demonstrate the level of consistency. Finally, as a case study, the ISO standards are applied to a CubeSat mission, thus demonstrating their usability on a relatively recent and popular class of satellite.

    Full Text Available A central authentication service to EPC (Electronic Product Code system architecture is proposed in our previous work. A challenge for a central service always arises that how it can ensure a certain level of delay while processing emergent data. The increasing data in the EPC system architecture is tags data. Therefore, authenticating increasing number of tag in the central authentication service with a deterministic time response is investigated and a distributed authentication service is designed in a layered approach. A distributed design of tag searching services in SOA (Service Oriented Architecture style is also presented. Using the SOA architectural style a self-adaptive authentication service over Cloud is also proposed for the central authentication service, that may also be extended for other applications.

    2016-07-01

    Patient-derived stem cells enable promising regenerative strategies, but display heterogenous cardiac reparative proficiency, leading to unpredictable therapeutic outcomes impeding practice adoption. Means to establish and certify the regenerative potency of emerging biotherapies are thus warranted. In this era of clinomics, deconvolution of variant cytoreparative performance in clinical trials offers an unprecedented opportunity to map pathways that segregate regenerative from non-regenerative states informing the evolution of cardio-regenerative quality systems. A maiden example of this approach is cardiopoiesis-mediated lineage specification developed to ensure regenerative performance. Successfully tested in pre-clinical and early clinical studies, the safety and efficacy of the cardiopoietic stem cell phenotype is undergoing validation in pivotal trials for chronic ischemic cardiomyopathy offering the prospect of a next-generation regenerative solution for heart failure.

  14. Existing FDA pathways have potential to ensure early access to, and appropriate use of, specialty drugs.

    Science.gov (United States)

    Kesselheim, Aaron S; Tan, Yongtian Tina; Darrow, Jonathan J; Avorn, Jerry

    2014-10-01

    Specialty drugs are notable among prescription drugs in that they offer the possibility of substantial clinical improvement, come with important risks of adverse events and mortality, can be complex to manufacture or administer, and are usually extremely costly. The Food and Drug Administration (FDA) plays a critical role in ensuring that patients who could benefit from specialty drugs have access to them in a timely fashion. In this article we review the different strategies that the FDA can use to approve and influence the post-approval prescribing of specialty drugs. When specialty drugs show promise in early clinical trials, the FDA can expedite the drugs' availability to patients through expanded access programs and expedited approval pathways that speed regulatory authorization. After approval, to ensure that specialty drugs are directed to the patients who are most likely to benefit from them, the FDA can limit the scope of the drugs' indications, encourage the development of companion diagnostic tests to indicate which patients should receive the drugs, or require that manufacturers subject them to Risk Evaluation and Mitigation Strategies to ensure that their use is appropriately limited to a restricted population that is aware of the drugs' risks and benefits. Implementing these existing regulatory approaches can promote timely patient access to specialty drugs while preventing expensive and potentially inappropriate overuse.

    Most medicinal products dispensed to patients have marketing authorization (MA) to ensure high quality of the product, safety, and efficacy. However, in daily practice, to treat patients adequately, there is a medical need for drugs that do not hold MA. To meet this medical need, medicinal products are used in clinical care without MA (unlicensed), such as products prepared by (local) pharmacies: the pharmaceutical preparations. Three types of pharmaceutical preparations are distinguished: (i) reconstitution in excess of summary of product characteristics; (ii) adaptation of a licensed medicinal product (outside its official labeling); (iii) medicinal products from an active pharmaceutical ingredient. Although unlicensed, patients may expect the same quality for these unlicensed pharmaceutical preparations as for the licensed medicinal products. To assure this quality, a proper risk-benefit assessment and proper documentation in (centralized) patient registries and linking to a national pharmacovigilance database should be in place. Based on a risk assessment matrix, requirements for quality assurance can be determined, which has impact on the level of documentation of a pharmaceutical preparation. In this paper, the approach for good documentation including quality assurance and benefit-risk assessment will be discussed and possibilities for patient registries are described to make these crucial preparations available for regular patient care. KEY POINTS Ensuring pharmaceutical quality and performing a proper benefit-risk assessment will guarantee safe use of pharmaceutical preparations. Good documentation of (ultra-)orphan treatments can be collected in centralized patient registries and should be combined with existing information in (inter)national databases and self-reflection of patients. Linking patient registries to a centralized database for adverse drug events is highly recommended as it increases safety control of the (ultra) orphan pharmaceutical

  16. Ensuring grid code harmonic compliance of wind farms

    2012-07-01

    The prevalence of cabled infrastructure associated with wind farms, combined with the surge in power-electronic interfaces in wind turbines and reactive power plant, has highlighted the pervasive nature of harmonics on electricity networks. Insufficient consideration is given to the effects of harmonics through the low prioritisation of power quality in the Front-End Engineering and Design (FEED) and a lack of awareness of the obligations of the respective parties involved. The resulting designs are incompatible with the requirements of the relevant Grid Codes. This can lead to delays, commercial exposure, restricted network access and subsequent loss of revenue. The obligations of the Transmission Owner (TO), System Operator (SO), and wind farm developer are discussed with respect to Grid Code requirements and the responsibilities of each party in ensuring compliance. The technical aspects of accessing harmonic compliance are described in the context of the design considerations which are made at the various stages of the project development. These include the shift in resonances within the host network, the modification of existing harmonic distortion, and the propagation of injected harmonics into the network and through to the EHV, HV and MV substations. The ensuing challenges associated with ensuring compliance through filter design are discussed in the context of relevant international standards, including UK ER G5/4-1, IEEE 519, EN 50160 and IEC 61000-3-6. The results indicate that shifts in resonances are more problematic to resolve, compared to the propagation of injected harmonics: Injected harmonics are readily absorbed through local filtering and thus the emissions are typically low; in contrast, the affects of shifts in resonances must be transferred back to the point of common coupling, resulting in complex local filtering. Early selection by the developer of appropriate transmission infrastructure and technology can lower the filtering requirement

    2017-05-05

    In low- and middle-income countries (LMICs), historically, household surveys have been carried out by face-to-face interviews to collect survey data related to risk factors for noncommunicable diseases. The proliferation of mobile phone ownership and the access it provides in these countries offers a new opportunity to remotely conduct surveys with increased efficiency and reduced cost. However, the near-ubiquitous ownership of phones, high population mobility, and low cost require a re-examination of statistical recommendations for mobile phone surveys (MPS), especially when surveys are automated. As with landline surveys, random digit dialing remains the most appropriate approach to develop an ideal survey-sampling frame. Once the survey is complete, poststratification weights are generally applied to reduce estimate bias and to adjust for selectivity due to mobile ownership. Since weights increase design effects and reduce sampling efficiency, we introduce the concept of automated active strata monitoring to improve representativeness of the sample distribution to that of the source population. Although some statistical challenges remain, MPS represent a promising emerging means for population-level data collection in LMICs. ©Alain Labrique, Emily Blynn, Saifuddin Ahmed, Dustin Gibson, George Pariyo, Adnan A Hyder.

    2017-07-01

    This review highlights the role of laboratory professionals and the strategies to be promoted in strict cooperation with clinicians for auditing, monitoring and improving the appropriateness of test request. The introduction of local pathways and care maps in agreement with international and national guidelines as well as the implementation of reflex testing and algorithms have a central role in guiding test request and in correcting the overuse/misuse of tests. Furthermore, removing obsolete tests from laboratory menu and vetting of restricted tests is recommended to increase cost-effectiveness. This saves costs and permits to introduce new biomarkers with increased diagnostic accuracy with a better impact on patient outcome. An additional issue is concerning the periodicity of (re)testing, accounting that only a minority of tests may be ordered as often as necessary. In the majority of cases, a minimum retesting interval should be introduced. The availability of effective computerised order entry systems is relevant in ensuring appropriate test requests and in providing an aid by automated rules that may stop inappropriate requests before they reach the laboratory.

  6. Robust mitotic entry is ensured by a latching switch

    Directory of Open Access Journals (Sweden)

    Chloe Tuck

    2013-07-01

    Cell cycle events are driven by Cyclin dependent kinases (CDKs and by their counter-acting phosphatases. Activation of the Cdk1:Cyclin B complex during mitotic entry is controlled by the Wee1/Myt1 inhibitory kinases and by Cdc25 activatory phosphatase, which are themselves regulated by Cdk1:Cyclin B within two positive circuits. Impairing these two feedbacks with chemical inhibitors induces a transient entry into M phase referred to as mitotic collapse. The pathology of mitotic collapse reveals that the positive circuits play a significant role in maintaining the M phase state. To better understand the function of these feedback loops during G2/M transition, we propose a simple model for mitotic entry in mammalian cells including spatial control over Greatwall kinase phosphorylation. After parameter calibration, the model is able to recapture the complex and non-intuitive molecular dynamics reported by Potapova et al. (Potapova et al., 2011. Moreover, it predicts the temporal patterns of other mitotic regulators which have not yet been experimentally tested and suggests a general design principle of cell cycle control: latching switches buffer the cellular stresses which accompany cell cycle processes to ensure that the transitions are smooth and robust.

  7. Ensuring the sustainability of EDF power plant operating capacity

    Francois, J.

    2009-01-01

    The life extension of the power plants is considered whereas EDF must face an acceleration of the retirement rates due to the fact that the first generations of the baby-boom are ageing 60 years, now. Between 2000 and 2006, EDF gradually set up a system of management of competencies. On the one hand, EDF moved from logic of relatively standardized training to a more individualized logic of acquisition of competencies. In addition, the objective of maintenance of internat competencies defined in 2000 was supplemented in 2003 by a prospective dimension intended to anticipate the departures in inactivity. Then in 2006 competencies of sub-contractors were taken into account. During this period I.R.S.N. has assessed 3 times this system of management. This article briefly presents the principal lessons driven from these evaluations. It accounts for the undeniable effort made by EDF to ensure the maintenance of its competencies. However, it stresses that a high level of vigilance is still needed because it is not stabilized already. (author)

    Egg shell sanitizing practices are necessary to improve microbiological safety of fresh eggs. In this work, fifteen fresh eggs samples of each (Balady, White and Brown eggs) were collected from different local supermarkets to evaluate their microbiological quality. The results indicated that Balady eggs were higher in microbial population in comparison with the two other varieties. Salmonella spp. was detected in 9 (60%) samples of Balady eggs. The effect of gamma irradiation at dose of 0, 2, 3 and 4 kGy on microbiological quality of Balady eggs during storage at 4±1 degree C for 35 days was studied. The effects of irradiation and storage on total cholesterol, and total carotenoids contents in Balady eggs were also investigated. The results showed that irradiation at 3 kGy reduced total aerobic bacterial counts. Coliform bacteria, E. coli and Salmonella spp. were completely eliminated. Total cholesterol and total carotenoids were decreased in yolk egg as a result of irradiation. Treated Balady eggs with irradiation dose of 3 kGy were efficient and sufficient for ensuring safety, maintain quality and extend shelf-life.

  9. Failure assessment techniques to ensure shipping container integrity

    International Nuclear Information System (INIS)

    McConnell, P.

    1986-02-01

    This report discusses several methodologies which may be used to ensure the structural integrity of containment systems to be used for the transport and storage of high-level radioactive substances. For economic reasons, shipping containers constructed of ferritic materials are being considered for manufacture by vendors in the US and Europe. Ferritic show an inherent transition from a ductile, high energy failure mode to a brittle, low energy fracture mode with decreasing temperature. Therefore, formal consideration of means by which to avoid unstable brittle fracture is necessary prior to the licensing of ferritic casks. It is suggested that failure of a shipping container wall be defined as occurring when a flaw extends through the outer wall of the containment system. Crack initiation which may lead to unstable brittle crack growth should therefore be prevented. It is suggested that a fundamental linear elastic fracture mechanics (lefm) approach be adopted on a case-by-case basis, applied perhaps by means of appropriate modifications to ASMA Section III or Section XI. A lefm analysis requires information concerning service temperatures, loading rates, flaw sizes, and applied stresses. Tentative judgments regarding these parameters for typical shipping containers have been made

  11. Ensuring quality in qualitative inquiry: using key concepts as guidelines

    Directory of Open Access Journals (Sweden)

    Debra Frances Campbell

    2013-09-01

    Full Text Available The field of qualitative scientific inquiry employs a fast-growing variety of approaches, whose traditions, procedures, and structures vary, depending on the type of study design and methodology (i.e., phenomenological, ethnographic, grounded theory, case study, action research, etc.. With the interpretive approach, researchers do not utilize the same measures of validity used in positivist approaches to scientific inquiry, since there is "...no one standard or accepted structure as one typically finds in quantitative research" (Creswell, 2007. With the absence of a single standard, how, then, is it possible for qualitative researchers to know whether or not their study was done with rigor, that it has validity, that it is ready to submit to their peers? The research literature is sprinkled with references to quality in qualitative inquiry, which helps to construe a study's validity. Markula (2008 suggests that we validate our study's findings by assuring readers that it was done "in the best possible way." While each research tradition has its own set of criteria for judging quality, we present here general concepts drawn from the literature. We hope this article will provide a framework from which qualitative researchers can judge their work before submitting it to their peers¸ one which will help ensure that their study was done "in the best possible way."

  12. EU actions to ensure the safety of tattoos and the protection of consumers.

    2015-01-01

    The number of tattooed persons has been continuously increasing in the last few years, particularly in the younger population. At the same time, the possibility of purchasing tattoo inks online is easier than ever worldwide. Consumers are not always sufficiently aware of the possible health problems associated with this 'cool fashion' if hygiene conditions are not respected and/or if the injected mixtures contain dangerous chemicals. Concerns about the possible health risks associated with such practices arise from the absence of a clear legislative framework, the lack of proper risk assessment of the chemicals used, and non-harmonised or missing hygiene and purity requirements, among other factors. There is a general consensus among all active stakeholders that EU harmonised rules would help to ensure a consistent high level of protection of consumers across the EU. © 2015 S. Karger AG, Basel.

    DeSantis, Carol; Naishadham, Deepa; Jemal, Ahmedin

    2013-05-01

    In this article, the American Cancer Society estimates the number of new cancer cases and deaths for African Americans and compiles the most recent data on cancer incidence, mortality, survival, and screening prevalence based upon incidence data from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data from the National Center for Health Statistics. It is estimated that 176,620 new cases of cancer and 64,880 deaths will occur among African Americans in 2013. From 2000 to 2009, the overall cancer death rate among males declined faster among African Americans than whites (2.4% vs 1.7% per year), but among females, the rate of decline was similar (1.5% vs 1.4% per year, respectively). The decrease in cancer death rates among African American males was the largest of any racial or ethnic group. The reduction in overall cancer death rates since 1990 in men and 1991 in women translates to the avoidance of nearly 200,000 deaths from cancer among African Americans. Five-year relative survival is lower for African Americans than whites for most cancers at each stage of diagnosis. The extent to which these disparities reflect unequal access to health care versus other factors remains an active area of research. Overall, progress in reducing cancer death rates has been made, although more can and should be done to accelerate this progress through ensuring equitable access to cancer prevention, early detection, and state-of-the-art treatments.

    Historically, infectious diseases caused considerable damage to human societies, and they continue to do so today. To help reduce their impact, mathematical models of disease transmission have been studied to help understand disease dynamics and inform prevention strategies. Vaccination-one of the most important preventive measures of modern times-is of great interest both theoretically and empirically. And in contrast to traditional approaches, recent research increasingly explores the pivotal implications of individual behavior and heterogeneous contact patterns in populations. Our report reviews the developmental arc of theoretical epidemiology with emphasis on vaccination, as it led from classical models assuming homogeneously mixing (mean-field) populations and ignoring human behavior, to recent models that account for behavioral feedback and/or population spatial/social structure. Many of the methods used originated in statistical physics, such as lattice and network models, and their associated analytical frameworks. Similarly, the feedback loop between vaccinating behavior and disease propagation forms a coupled nonlinear system with analogs in physics. We also review the new paradigm of digital epidemiology, wherein sources of digital data such as online social media are mined for high-resolution information on epidemiologically relevant individual behavior. Armed with the tools and concepts of statistical physics, and further assisted by new sources of digital data, models that capture nonlinear interactions between behavior and disease dynamics offer a novel way of modeling real-world phenomena, and can help improve health outcomes. We conclude the review by discussing open problems in the field and promising directions for future research.

    Administrative data can be used to support research, such as in the UK Biobank. Hospital Episode Statistics (HES) are national data for England that include contain ICD-10 diagnoses for inpatient mental healthcare episodes, but the validity of these diagnoses for research purposes has not been assessed. 250 peoples' HES records were selected based on a HES recorded inpatient stay at the South London and Maudsley NHS Foundation Trust with a diagnosis of schizophrenia, a wider schizophrenia spectrum disorder, bipolar affective disorder or unipolar depression. A gold-standard research diagnosis was made using Clinical Records Interactive Search pseudonymised electronic patient records using, and the OPCRIT+ algorithm. Positive predictive value at the level of lifetime psychiatric disorder was 100%, and at the level of lifetime diagnosis in the four categories of schizophrenia, wider schizophrenia spectrum, bipolar or unipolar depression was 73% (68-79). Agreement varied by diagnosis, with schizophrenia having the highest PPV at 90% (80-96). Each person had an average of five psychiatric HES records. An algorithm that looked at the last recorded psychiatric diagnosis led to greatest overall agreement with the research diagnosis. For people who have a HES record from a psychiatric admission with a diagnosis of schizophrenia spectrum disorder, bipolar affective disorder or unipolar depression, HES records appear to be a good indicator of a mental disorder, and can provide a diagnostic category with reasonable certainty. For these diagnoses, HES records can be an effective way of ascertaining psychiatric diagnosis.

  6. Piezoelectric sensing and non-parametric statistical signal processing for health monitoring of hysteretic dampers used in seismic-resistant structures

    Science.gov (United States)

    Gallego, A.; Benavent-Climent, A.; Romo-Melo, L.

    2015-08-01

    The paper proposes a new application of non-parametric statistical processing of signals recorded from vibration tests for damage detection and evaluation on I-section steel segments. The steel segments investigated constitute the energy dissipating part of a new type of hysteretic damper that is used for passive control of buildings and civil engineering structures subjected to earthquake-type dynamic loadings. Two I-section steel segments with different levels of damage were instrumented with piezoceramic sensors and subjected to controlled white noise random vibrations. The signals recorded during the tests were processed using two non-parametric methods (the power spectral density method and the frequency response function method) that had never previously been applied to hysteretic dampers. The appropriateness of these methods for quantifying the level of damage on the I-shape steel segments is validated experimentally. Based on the results of the random vibrations, the paper proposes a new index that predicts the level of damage and the proximity of failure of the hysteretic damper.

  7. Whole genome sequencing: an efficient approach to ensuring food safety

    Science.gov (United States)

    2017-09-01

    Whole genome sequencing is an effective, powerful tool that can be applied to a wide range of public health and food safety applications. A major difference between WGS and the traditional typing techniques is that WGS allows all genes to be included in the analysis, instead of a well-defined subset of genes or variable intergenic regions. Also, the use of WGS can facilitate the understanding of contamination/colonization routes of foodborne pathogens within the food production environment, and can also afford efficient tracking of pathogens’ entry routes and distribution from farm-to-consumer. Tracking foodborne pathogens in the food processing-distribution-retail-consumer continuum is of the utmost importance for facilitation of outbreak investigations and rapid action in controlling/preventing foodborne outbreaks. Therefore, WGS likely will replace most of the numerous workflows used in public health laboratories to characterize foodborne pathogens into one consolidated, efficient workflow.

    To explore and compare Finnish and British nursing students' perceptions of their learning about patient safety in clinical settings. Patient safety culture and practices in different health care organisations and clinical units varies, posing challenges for nursing students' learning about patient safety during their clinical placements. Patient safety as a growing international concern has challenged health care professionals globally requiring a comprehensive review. International studies comparing nursing education about patient safety are lacking. A cross-sectional comparative study. The participants were final year preregistration nursing students from two universities of applied sciences in Finland (n = 195) and from two universities in England, UK (n = 158). The data were collected with the Patient Safety in Nursing Education Questionnaire and analysed with principal component analysis, Pearson Chi-Square and Mann-Whitney U tests and logistic regression. Finnish nursing students had significantly more critical perceptions on their learning about patient safety in clinical settings than their British peers. A strong predictor for differences was supportive and systems-based approaches in learning to ensure patient safety. Notably, fewer Finnish students had practiced reporting of incidents in clinical settings compared to British students. In both countries, the students held learning about patient safety in higher esteem compared to their learning experiences in clinical settings. Nursing students appear to want more learning opportunities related to patient safety compared to the reality in clinical settings. Learning systematically from errors in a supportive environment and having systems-based approaches to ensure patient safety are essential elements for nursing students' learning about safe practice. Finnish students seem to experience more barriers in learning about safe practices and to report errors than the British students. Health care

  1. Collaborative efforts are needed to ensure proper knowledge dissemination of telemedicine projects.

    Science.gov (United States)

    Jakobsen, Neel Kolthoff; Jensen, Lena Sundby; Kayser, Lars

    2014-09-01

    Telemedicine is often seen as the solution to the challenge of providing health care for an increasing number of people with chronic conditions. Projects are often organised locally and based on the involvement of stakeholders with a wide range of backgrounds. It can be challenging to ensure that projects are based on previous experience and that they do not repeat previous studies. To better understand these challenges and current practice, we examined telemedicine projects funded in the 2008-2010 period to explore where, how and to what extent results from the projects were documented and disseminated. Public and private funds were contacted for information about telemedicine studies focusing on people residing in their homes. After an initial screening of titles and abstracts, 19 projects were identified. The managers of the projects were contacted and information about project results and dissemination were obtained. More than half of all projects were disseminated to professionals as well as to the public and used two-way communication. However, it was generally difficult to obtain an overview of the projects due to dynamic changes in names and scopes. We propose that the funding authorities require designs comprising proper evaluation models that will subsequently allow the investigators to publish their findings. Furthermore, a dissemination plan comprising both peers and other professions should be made mandatory. The investigators should ensure proper documentation and dissemination of changes both during and after the projects in order to ensure transparency, and national or international organisations should establish a database with relevant data fields. not relevant. not relevant.

    Use of scientific evidence aids in ensuring that public health interventions have the best possible health and economic return on investment. We describe use of academic journals by state health department chronic disease prevention staff to find public health evidence. We surveyed more than 900 state health department staff from all states and the District of Columbia. Participants identified top journals or barriers to journal use. We used descriptive statistics to examine individual and aggregate state health department responses. On average, 45.7% of staff per state health department use journals. Common barriers to use included lack of time, lack of access, and expense. Strategies for increasing journal use are provided.

    Statistics is the branch of mathematics that deals with real-life problems. As such, it is an essential tool for economists. Unfortunately, the way you and many other economists learn the concept of statistics is not compatible with the way economists think and learn. The problem is worsened by the use of mathematical jargon and complex derivations. Here's a book that proves none of this is necessary. All the examples and exercises in this book are constructed within the field of economics, thus eliminating the difficulty of learning statistics with examples from fields that have no relation to business, politics, or policy. Statistics is, in fact, not more difficult than economics. Anyone who can comprehend economics can understand and use statistics successfully within this field, including you!

In eventuality of emergency situations, people need to be rehabilitated and provided with an adequate supply of drinking water, the most essential natural resource needed for survival, which is often not easily available even during non-disaster periods. In the aftermath of a natural or human-made disaster affecting mankind and livestock, the prime aim is to ensure supply of safe water to reduce the occurrence and spread of water borne disease due to interrupted, poor and polluted water supply. Chemical, biological, radiological and nuclear (CBRN) emergencies augment the dilemma as an additional risk of "contamination" is added. The associated risks posed to health and life should be reduced to as low as reasonably achievable. Maintaining a high level of preparedness is the crux of quick relief and efficient response to ensure continuous supply of safe water, enabling survival and sustenance. The underlying objective would be to educate and train the persons concerned to lay down the procedures for the detection, cleaning, and treatment, purification including desalination, disinfection, and decontamination of water. The basic information to influence the organization of preparedness and execution of relief measures at all levels while maintaining minimum standards in water management at the place of disaster, are discussed in this article.

  15. Protecting me from my Directive: Ensuring Appropriate Safeguards for Advance Directives in Dementia.

    Auckland, Cressida

    2018-02-01

    With one in six people over 80 now suffering from dementia, advance directives provide an important means of empowerment. Upholding directives in the context of dementia, however, raises extra challenges, given the potential for the directive to conflict with an assessment of what is in the person's current best interests. Given the profound harm that tying a person with dementia to their previous wishes can do, it is essential that we have sufficient safeguards in place to ensure that we only uphold such directives where we can be sure they are truly autonomous and are intended to apply to the situation at hand-safeguards which are at present, severely lacking. This article will consider various mechanisms by which safeguards can be built into the legal regime to ensure that the original decision is autonomous, including making it mandatory for the person to undergo a consultation with a healthcare professional, which would involve a contemporaneous capacity assessment. Clinicians must also be confident that the directive applies to the situation at hand. Introducing formalities, including a standardised (though not mandatory) proforma, may help to enhance specificity about when the directive is triggered, and to what treatments it relates, to enable clinicians to better assess the directive's applicability. A national registry for advance directives might also be beneficial. It will be argued that health care professionals will have to play a much greater role in the drafting and registering of advance directives, if we are to feel comfortable in upholding them.

  16. Responsible science: Ensuring the integrity of the research process, volume 1

    Science.gov (United States)

    This report thoughtfully examines the challenges posed in ensuring that the search for truth reflects adherence to ethical standards. In recent years, we have learned, sometimes painfully, that not all scientists adhere to this obligation. Reports of falsified research results and plagiarism involving both junior and senior scientists have stimulated doubts and criticism about the ways in which misconduct in science is addressed by the research community. Misconduct in science is now being publicly examined in all of its aspects; how misconduct is defined, the process by which misconduct is discovered, and procedures for judging innocence or guilt and assessing penalties. Also being explored are the appropriate roles of individuals, research institutions, journals, government research agencies, and the legal system. Issues of misconduct and integrity in science present complex questions. These issues require the sustained attention of all members of the research community as well as of leaders in the public and private sector who are concerned with safeguarding the health of science. In this regard ensuring the integrity of the research process is similar to assuring safety in the workplace: it is a process that requires continued participation from all levels of the entire research enterprise--the practitioners, the host institutions, the sponsors in government, and the legislators who provide the funds.

  17. Ensuring the First Breath: A Growing Accountability of Midwifery in Bangladesh

    2017-01-01

    Full Text Available Successful women empowerment relies on providing quality infrastructure facilities to avail maternal healthcare on the national level. In this regard, ensuring women’s access to quality midwifery services is an important consideration. The major intervention for safe maternity is to be enhanced to enable the presence of the skilled midwifery to ensure the quality emergency obstetric care. Therefore, the scope of practice of a midwife is very critical in the supervision of the orderly physiological processes of pregnancy, labor, birth, and the postpartum phase. The midwife as an autonomous practitioner is expected to be competent and accountable for her practice. In Bangladesh, the number of women having the baby at home by unskilled personnel is quite high. Therefore, the government strives to educate midwives and commits to reducing maternal and newborn mortality and morbidity. This study explores the contemporary situation of maternity health to provide a critical understanding of the growing importance of the role of midwifery in Bangladesh. With this, the paper examines the way maternity services in Bangladesh transformed from a social to a medical model over the twentieth century and infers how the social agenda was part of this process.

    2018-01-30

    Analysis of sexual history data intended to describe sexual networks presents many challenges arising from the fact that most surveys collect information on only a very small fraction of the population of interest. In addition, partners are rarely identified and responses are subject to reporting biases. Typically, each network statistic of interest, such as mean number of sexual partners for men or women, is estimated independently of other network statistics. There is, however, a complex relationship among networks statistics; and knowledge of these relationships can aid in addressing concerns mentioned earlier. We develop a novel method that constrains a posterior predictive distribution of a collection of network statistics in order to leverage the relationships among network statistics in making inference about network properties of interest. The method ensures that inference on network properties is compatible with an actual network. Through extensive simulation studies, we also demonstrate that use of this method can improve estimates in settings where there is uncertainty that arises both from sampling and from systematic reporting bias compared with currently available approaches to estimation. To illustrate the method, we apply it to estimate network statistics using data from the Chicago Health and Social Life Survey. Copyright © 2017 John Wiley & Sons, Ltd.

    2005-01-01

    In July 1998, the Ministry of Health (MS) published the Guidelines for Radiological Protection in Medical and Dental Radiodiagnosis that became known as Portaria 453 - Ordinance 453. This study is designed to evaluate the dentists of Rio de Janeiro on the knowledge and application of the criteria laid down by Ordinance. For this, it was sent to dentists, a form with 13 questions. The issues are related to the use of personal protective clothing (VPI), working procedures for the exam and processing of the image, radioprotection training and quality control. Of 1528 dentists, only 40% have a copy of the Ordinance. Regarding the use of VPI, 94% has lead apron and 76% thyroid shield. Only 63% of dentists observe patients during exposure to X-rays. In 96% of doctor's rooms the revelation of the film is made in a portable box, 71% of these use the visual method to stop processing. The results show the need for greater dissemination of the Ordinance by the odontologist's associations; for an educational work on the topics discussed and training that allow the dentists be prepared to apply the correct work procedures in the production of diagnostic imaging with X-rays

    2017-07-01

    In 2008, physical therapists published the first neck pain clinical practice guidelines. These guidelines have been updated and are now available in the July 2017 issue of JOSPT. To update these guidelines, physical therapists teamed with the International Collaboration on Neck Pain to identify leading practices. These revised guidelines provide direction to clinicians as they screen, evaluate, diagnose, and make treatment-based classifications of neck pain. They also outline the best nonsurgical treatment options based on the published literature. At the end of the day, the best care is a combination of the leading science, the clinical expertise of your health care provider, and your input as the patient. These guidelines help inform the first step in this process. J Orthop Sports Phys Ther 2017;47(7):513. doi:10.2519/jospt.2017.0508.

    2013-05-01

    This case-study compared traditional, face-to-face classroom-based teaching with asynchronous online learning and teaching methods in two sets of students undertaking a problem-based learning module in the multilevel and exploratory factor analysis of longitudinal data as part of a Masters degree in Public Health at Maastricht University. Students were allocated to one of the two study variants on the basis of their enrolment status as full-time or part-time students. Full-time students (n = 11) followed the classroom-based variant and part-time students (n = 12) followed the online asynchronous variant which included video recorded lectures and a series of asynchronous online group or individual SPSS activities with synchronous tutor feedback. A validated student motivation questionnaire was administered to both groups of students at the start of the study and a second questionnaire was administered at the end of the module. This elicited data about student satisfaction with the module content, teaching and learning methods, and tutor feedback. The module coordinator and problem-based learning tutor were also interviewed about their experience of delivering the experimental online variant and asked to evaluate its success in relation to student attainment of the module's learning outcomes. Student examination results were also compared between the two groups. Asynchronous online teaching and learning methods proved to be an acceptable alternative to classroom-based teaching for both students and staff. Educational outcomes were similar for both groups, but importantly, there was no evidence that the asynchronous online delivery of module content disadvantaged part-time students in comparison to their full-time counterparts.

  6. Strategies for ensuring global consistency/comparability of water-quality data

    Science.gov (United States)

    Klein, J.M.

    1999-01-01

    In the past 20 years the water quality of the United States has improved remarkably-the waters are safer for drinking, swimming, and fishing. However, despite many accomplishments, it is still difficult to answer such basic questions as: 'How clean is the water?' and 'How is it changing over time?' These same questions exist on a global scale as well. In order to focus water-data issues in the United States, a national Intergovernmental Task Force on Monitoring Water Quality (ITFM) was initiated for public and private organizations, whereby key elements involved in data collection, analysis, storage, and management could be made consistent and comparable. The ITFM recommended and its members are implementing a nationwide strategy to improve water-quality monitoring, assessment, and reporting activities. The intent of this paper is to suggest that a voluntary effort be initiated to ensure the comparability and utility of hydrological data on a global basis. Consistent, long-term data sets that are comparable are necessary in order to formulate ideas regarding regional and global trends in water quantity and quality. The author recommends that a voluntary effort similar to the ITFM effort be utilized. The strategy proposed would involve voluntary representation from countries and international organizations (e.g. World Health Organization) involved in drinking-water assessments and/or ambient water-quality monitoring. Voluntary partnerships such as this will improve curability to reduce health risks and achieve a better return on public and private investments in monitoring, environmental protection, and natural resource management, and result in a collaborative process that will save millions of dollars.In this work it is suggested that a voluntary effort be initiated to ensure the comparability and utility of hydrological data on a global basis.

    2007-01-01

    This book provides a comprehensive presentation of the basics of statistical physics. The first part explains the essence of statistical physics and how it provides a bridge between microscopic and macroscopic phenomena, allowing one to derive quantities such as entropy. Here the author avoids going into details such as Liouville’s theorem or the ergodic theorem, which are difficult for beginners and unnecessary for the actual application of the statistical mechanics. In the second part, statistical mechanics is applied to various systems which, although they look different, share the same mathematical structure. In this way readers can deepen their understanding of statistical physics. The book also features applications to quantum dynamics, thermodynamics, the Ising model and the statistical dynamics of free spins.

  10. ENSURING ADEQUATE SAFETY WHEN USING HYDROGEN AS A FUEL

    Energy Technology Data Exchange (ETDEWEB)

    Coutts, D

    2007-01-22

    Demonstration projects using hydrogen as a fuel are becoming very common. Often these projects rely on project-specific risk evaluations to support project safety decisions. This is necessary because regulations, codes, and standards (hereafter referred to as standards) are just being developed. This paper will review some of the approaches being used in these evolving standards, and techniques which demonstration projects can implement to bridge the gap between current requirements and stakeholder desires. Many of the evolving standards for hydrogen-fuel use performance-based language, which establishes minimum performance and safety objectives, as compared with prescriptive-based language that prescribes specific design solutions. This is being done for several reasons including: (1) concern that establishing specific design solutions too early will stifle invention, (2) sparse performance data necessary to support selection of design approaches, and (3) a risk-adverse public which is unwilling to accept losses that were incurred in developing previous prescriptive design standards. The evolving standards often contain words such as: ''The manufacturer shall implement the measures and provide the information necessary to minimize the risk of endangering a person's safety or health''. This typically implies that the manufacturer or project manager must produce and document an acceptable level of risk. If accomplished using comprehensive and systematic process the demonstration project risk assessment can ease the transition to widespread commercialization. An approach to adequately evaluate and document the safety risk will be presented.

    There are many textbooks which describe current methods of statistical analysis, while neglecting related theory. There are equally many advanced textbooks which delve into the far reaches of statistical theory, while bypassing practical applications. But between these two approaches is an unfilled gap, in which theory and practice merge at an intermediate level. Professor M. G. Bulmer's Principles of Statistics, originally published in 1965, was created to fill that need.

    Einstein argued that since quantum mechanics is not a fundamental theory it cannot be regarded as in any sense final. The pure statistical states of the quantum theory are not dispersion-free. In this sense, the theory is significantly statistical. The problem investigated in this paper is to determine under what conditions is a significalty statistical theory correctly regarded as fundamental. The solution developed in this paper is that a statistical theory is fundamental only if it is complete; moreover the quantum theory is complete. (B.R.H.)

    Statistics is the activity of inferring results about a population given a sample. Historically, statistics books assume an underlying distribution to the data (typically, the normal distribution) and derive results under that assumption. Unfortunately, in real life, one cannot normally be sure of the underlying distribution. For that reason, this book presents a distribution-independent approach to statistics based on a simple computational counting idea called resampling. This book explains the basic concepts of resampling, then systematically presents the standard statistical measures along

  20. Ensuring sustained ACT production and reliable artemisinin supply

    Olliaro Piero

    2007-09-01

    Full Text Available Abstract Introduction This paper reviews recent trends in the production, supply and price of the active ingredients as well as finished ACT products. Production and cost data provided in this paper are based on an ongoing project (Artepal. Stability data are derived from a development project on rectal artesunate. Discussion The artemisinin raw material and its derivatives appear to be very stable compared to the finished products. Supply of artemisinin changed in May 2004 when the Global Fund shifted financial support to qualified countries from chloroquine or sulphadoxine-pyrimethamine to an ACT for treatment of malaria. First, there was a sudden shortage of the starting material, and short term scarcity led to a steep rise in API price: it increased dramatically in 2004, from $350 per kg to more than $1000. Second, there was a parallel increase in the number of companies extracting artemisinin from 10 to 80 between 2003 and 2005 in China, and from 3 to 20 in Vietnam. Commercial cultivation began also in East Africa and Madagascar. A steady and predictable demand for the crop can eliminate such wide fluctuations and indirectly contribute to price stability of the herb, the API and ACT. With appropriate mechanisms to reduce those fluctuations, the cost of artemisinin might decrease sustainably to US$ 250–300 per kg. Conclusion Today the global health community is facing the risk of another cyclical swing with lower demand feeding into reduced planting of A. annua and, thereafter, a new shortage of the raw material and higher API prices. International donors, the largest purchasers for ACTs could better coordinate their activities, in order to guarantee purchase of ACTs and consequently of API with manufacturers. In parallel, the base of quality producers of APIs and finished ACT products needs to be broadened. While the ACT programme is still in its early stages, the consequences of another wave of artemisinin and ACT shortages would
