  1. Epidemiology applied to health physics

    International Nuclear Information System (INIS)

    The technical program of the mid-year meeting of the Health Physics Society, entitled Epidemiology Applied to Health physics, was developed to meet three objectives: (1) give health physicists a deeper understanding of the basics of epidemiological methods and their use in developing standards, regulations, and criteria and in risk assessment; (2) present current reports on recently completed or on-going epidemiology studies; and (3) encourage greater interaction between the health physics and epidemiology disciplines. Included are studies relating methods in epidemiology to radiation protection standards, risk assessment from exposure to bone-seekers, from occupational exposures in mines, mills and nuclear facilities, and from radioactivity in building materials

  3. Methodological exploratory study applied to occupational epidemiology

    International Nuclear Information System (INIS)

    The utilization of epidemiologic methods and techniques has been object of practical experimentation and theoretical-methodological reflection in health planning and programming process. Occupational Epidemiology is the study of the causes and prevention of diseases and injuries from exposition and risks in the work environment. In this context, there is no intention to deplete such a complex theme but to deal with basic concepts of Occupational Epidemiology, presenting the main characteristics of the analysis methods used in epidemiology, as investigate the possible determinants of exposition (chemical, physical and biological agents). For this study, the social-demographic profile of the IPEN-CNEN/SP work force was used. The knowledge of this reference population composition is based on sex, age, educational level, marital status and different occupations, aiming to know the relation between the health aggravating factors and these variables. The methodology used refers to a non-experimental research based on a theoretical methodological practice. The work performed has an exploratory character, aiming a later survey of indicators in the health area in order to analyze possible correlations related to epidemiologic issues. (author)

  4. Epidemiologic research program: Selected bibliography

    International Nuclear Information System (INIS)

    This bibliography is a current listing of scientific reports from epidemiologic and related activities sponsored by the Department of Energy. The Office of Epidemiology and Health Surveillance now is the departmental focal point for these activities and any others relating to the study of human health effects. The Office's mission is evolving to encompass the new role of the Department in environmental restoration, weapons dismantlement and nuclear material storage, and development of new energy technologies. Publications in these areas will be included in future editions of the bibliography. The present edition brings the listing up to date, and should facilitate access to specific reports. The program has been divided into several general areas of activity: the Radiation Effects Research Foundation, which supports studies of survivors of the atomic weapons in Hiroshima and Nagasaki; mortality and morbidity studies of DOE workers; studies on internally deposited alpha emitters; medical/histologic studies; studies on the genetic aspects of radiation damage; community health surveillance studies; and the development of computational techniques and of databases to make the results as widely useful as possible

  5. Does terrestrial epidemiology apply to marine systems?

    McCallum, Hamish I.; Kuris, Armand M.; Harvell, C. Drew; Lafferty, Kevin D.; Smith, Garriet W.; Porter, James

    2004-01-01

    Most of epidemiological theory has been developed for terrestrial systems, but the significance of disease in the ocean is now being recognized. However, the extent to which terrestrial epidemiology can be directly transferred to marine systems is uncertain. Many broad types of disease-causing organism occur both on land and in the sea, and it is clear that some emergent disease problems in marine environments are caused by pathogens moving from terrestrial to marine systems. However, marine systems are qualitatively different from terrestrial environments, and these differences affect the application of modelling and management approaches that have been developed for terrestrial systems. Phyla and body plans are more diverse in marine environments and marine organisms have different life histories and probably different disease transmission modes than many of their terrestrial counterparts. Marine populations are typically more open than terrestrial ones, with the potential for long-distance dispersal of larvae. Potentially, this might enable unusually rapid propagation of epidemics in marine systems, and there are several examples of this. Taken together, these differences will require the development of new approaches to modelling and control of infectious disease in the ocean.

  6. Applying molecular epidemiology in pediatric leukemia.

    Science.gov (United States)

    Schiffman, Joshua D

    2016-02-01

    Molecular epidemiology is the study of genetic and environmental risk for disease, with much effort centered on cancer. Childhood leukemia occurs in nearly a third of all patients newly diagnosed with pediatric cancer. only a small percentage of these new cases of childhood leukemia are associated with high penetrant hereditary cancer syndromes. Childhood leukemia, especially acute lymphoblastic leukemia, has been associated with a dysregulated immune system due to delayed infectious exposure at a young age. Identical twins with childhood leukemia suggest that acute lymphoblastic leukemia begins in utero and that the concordant presentation is due to a shared preleukemia subclone via placental transfer. Investigation of single nucleotide polymorphisms within candidate genes find that leukemia risk may be attributed to population-based polymorphisms affecting folate metabolism, xenobiotic metabolism, DNA repair, immunity, and B-cell development. More recently, genome-wide association studies for leukemia risk has led investigators to genes associated with B-cell development. When describing leukemia predisposition due to hereditary cancer syndromes, the following 6 categories become apparent on the basis of biology and clinical presentation: (1) genetic instability/DNA repair syndromes, (2) cell cycle/differentiation syndromes, (3) bone marrow failure syndromes, (4) telomere maintenance syndromes, (5) immunodeficiency syndromes, and (6) transcription factor syndromes and pure familial leukemia. understanding the molecular epidemiology of childhood leukemia can affect the treatment and tumor surveillance strategies for these high risk patients and their family members.

    Full Text Available The main strategy of the worldwide Program of Poliomyelitis Eradication is based on immunization with oral poliovirus vaccine and active epidemiological surveillance aimed to demonstrate the absence of wild poliovirus circulation. The specification of the surveillance in the program, reporting and investigation of certain syndrome – the acute flaccid paralysis - as a specific feature of surveillance of poliomyelitis, is a new experience both for clinicians and epidemiologists. Along with the achieved results, problems in conducting the active epidemiological surveillance in Serbia, applied measures, and suggestions for improving its quality were presented. This experience might help in implementing the active surveillance for some other diseases that could be prevented by vaccine immunization.

  15. A model of malaria epidemiology involving weather, exposure and transmission applied to north East India.

    Directory of Open Access Journals (Sweden)

    Prashant Goswami

    Full Text Available BACKGROUND: Quantitative relations between weather variables and malaria vector can enable pro-active control through meteorological monitoring. Such relations are also critical for reliable projections in a changing climate, especially since the vector abundance depends on a combination of weather variables, each in a given range. Further, such models need to be region-specific as vector population and exposure depend on regional characteristics. METHODS: We consider days of genesis based on daily temperature, rainfall and humidity in given ranges. We define a single model parameter based on estimates of exposure and transmission to calibrate the model; the model is applied to 12 districts of Arunachal Pradesh, a region endemic to malaria. The epidemiological data is taken as blood samples that test positive. The meteorological data is adopted from NCEP daily Reanalysis on a global grid; population data is used to estimate exposure and transmission coefficients. RESULTS: The observed annual cycles (2006-2010 and the interannual variability (2002-2010 of epidemiology are well simulated for each of the 12 districts by the model. While no single weather variable like temperature can reproduce the observed epidemiology, a combination of temperature, rainfall and humidity provides an accurate description of the annual cycle as well as the inter annual variability over all the 12 districts. CONCLUSION: Inclusion of the three meteorological variables, along with the expressions for exposure and transmission, can quite accurately represent observed epidemiology over multiple locations and different years. The model is potentially useful for outbreak forecasts at short time scales through high resolution weather monitoring; however, validation with longer and independent epidemiological data is required for more robust estimation of realizable skill. While the model has been examined over a specific region, the basic algorithm is easily applicable to

    Fully utilize current and near-term airborne and spaceborne assets and capabilities. NASA spaceborne instruments are for research but can be applied to natural disaster response as appropriate. NASA airborne instruments can be targeted specifically for disaster response. Could impact research programs. Better flow of information improves disaster response. Catalog capability, product, applicable disaster, points of contact. Ownership needs to come from the highest level of NASA - unpredictable and irregular nature of disasters requires contingency funding for disaster response. Build-in transfer of applicable natural disaster research capabilities to operational functionality at other agencies (e.g., USFS, NOAA, FEMA...) at the outset, whenever possible. For the Decadal Survey Missions, opportunities exist to identify needs and requirements early in the mission design process. Need to understand additional needs and commitments for meeting the needs of the disaster community. Opportunity to maximize disaster response and mitigation from the Decadal Survey Missions. Additional needs or capabilities may require agency contributions.

  18. Fusion programs in applied plasma physics

    International Nuclear Information System (INIS)

    The objectives of the theoretical science program are: To support the interpretation of present experiments and predict the outcome of future planned experiments; to improve on existing models and codes and validate against experimental results; and to conduct theoretical physics development of advanced concepts with applications for DIII-D and future devices. Major accomplishments in FY91 include the corroboration between theory and experiment on MHD behavior in the second stable regime of operation on DIII-D, and the frequency and mode structure of toroidal Alfven eigenmodes in high beta, shaped plasmas. We have made significant advances in the development of the gyro-Landau fluid approach to turbulence simulation which more accurately models kinetic drive and damping mechanisms. Several theoretical models to explain the bifurcation phenomenon in L- to H-mode transition were proposed providing the theoretical basis for future experimental verification. The capabilities of new rf codes have been upgraded in response to the expanding needs of the rf experiments. Codes are being employed to plan for a fully non-inductive current drive experiment in a high beta, enhanced confinement regime. GA's experimental effort in Applied Physics encompasses two advanced diagnostics essential for the operation of future fusion experiments: Alpha particle diagnostic, and current and density profile diagnostics. This paper discusses research in all these topics

    Infections of poultry species with virulent strains of Newcastle disease virus (NDV) cause Newcastle disease (ND), one of the most economically significant and devastating diseases for poultry producers worldwide. Biological engagement programs between the Southeast Poultry Research Laboratory (SEPRL) of the United States Department of Agriculture and laboratories from Russia, Pakistan, Ukraine, Kazakhstan, and Indonesia collectively have produced a better understanding of the genetic diversity and evolution of the viruses responsible for ND, which is crucial for the control of the disease. The data from Kazakhstan, Russia, and Ukraine identified possible migratory routes for birds that may carry both virulent NDV (vNDV) and NDV of low virulence into Europe. In addition, related NDV strains were isolated from wild birds in Ukraine and Nigeria, and from birds in continental USA, Alaska, Russia, and Japan, identifying wild birds as a possible mechanism of intercontinental spread of NDV of low virulence. More recently, the detection of new sub-genotypes of vNDV suggests that a new, fifth, panzootic of ND has already originated in Southeast Asia, extended to the Middle East, and is now entering into Eastern Europe. Despite expected challenges when multiple independent laboratories interact, many scientists from the collaborating countries have successfully been trained by SEPRL on molecular diagnostics, best laboratory practices, and critical biosecurity protocols, providing our partners the capacity to further train other employes and to identify locally the viruses that cause this OIE listed disease. These and other collaborations with partners in Mexico, Bulgaria, Israel, and Tanzania have allowed SEPRL scientists to engage in field studies, to elucidate more aspects of ND epidemiology in endemic countries, and to understand the challenges that the scientists and field veterinarians in these countries face on a daily basis.

    The Royal Thai Government requested assistance of the United States Agency for International Development for the development and implementation of a more comprehensive scientific approach to the design, operation, and evaluation of Thailand's weather modification program. Upon visiting Thailand, a team of American scientists recommended a 5-year developmental program to improve Thai technical capabilities through training, additional equipment, and a demonstration cloud seed project. The program will test for an increase in rainfall from: (1) warm clouds seeded with hygroscopic agents; and (2) cold clouds seeded for dynamic effects with glaciogenic materials. The field program will be conducted in the Nam Mae Tun River Watershed of western Thailand. The primary response variable is rainfall measured by rain-gauge-adjusted radar. Given equal numbers of warm and cold cloud units and typical operations problems and weather variability, at least four seasons of field experimentation are required.

    Friedl, L. A.; Cox, L.

    2008-12-01

    The NASA Applied Sciences Program collaborates with organizations to discover and demonstrate applications of NASA Earth science research and technology to decision making. The desired outcome is for public and private organizations to use NASA Earth science products in innovative applications for sustained, operational uses to enhance their decisions. In addition, the program facilitates the end-user feedback to Earth science to improve products and demands for research. The Program thus serves as a bridge between Earth science research and technology and the applied organizations and end-users with management, policy, and business responsibilities. Since 2002, the Applied Sciences Program has sponsored over 115 applications-oriented projects to apply Earth observations and model products to decision making activities. Projects have spanned numerous topics - agriculture, air quality, water resources, disasters, public health, aviation, etc. The projects have involved government agencies, private companies, universities, non-governmental organizations, and foreign entities in multiple types of teaming arrangements. The paper will examine this set of applications projects and present specific examples of successful use of Earth science in decision making. The paper will discuss scientific, organizational, and management factors that contribute to or impede the integration of the Earth science research in policy and management. The paper will also present new methods the Applied Sciences Program plans to implement to improve linkages between science and end users.

  16. Simulating Nationwide Pandemics: Applying the Multi-scale Epidemiologic Simulation and Analysis System to Human Infectious Diseases

    Energy Technology Data Exchange (ETDEWEB)

    Dombroski, M; Melius, C; Edmunds, T; Banks, L E; Bates, T; Wheeler, R

    2008-09-24

    This study uses the Multi-scale Epidemiologic Simulation and Analysis (MESA) system developed for foreign animal diseases to assess consequences of nationwide human infectious disease outbreaks. A literature review identified the state of the art in both small-scale regional models and large-scale nationwide models and characterized key aspects of a nationwide epidemiological model. The MESA system offers computational advantages over existing epidemiological models and enables a broader array of stochastic analyses of model runs to be conducted because of those computational advantages. However, it has only been demonstrated on foreign animal diseases. This paper applied the MESA modeling methodology to human epidemiology. The methodology divided 2000 US Census data at the census tract level into school-bound children, work-bound workers, elderly, and stay at home individuals. The model simulated mixing among these groups by incorporating schools, workplaces, households, and long-distance travel via airports. A baseline scenario with fixed input parameters was run for a nationwide influenza outbreak using relatively simple social distancing countermeasures. Analysis from the baseline scenario showed one of three possible results: (1) the outbreak burned itself out before it had a chance to spread regionally, (2) the outbreak spread regionally and lasted a relatively long time, although constrained geography enabled it to eventually be contained without affecting a disproportionately large number of people, or (3) the outbreak spread through air travel and lasted a long time with unconstrained geography, becoming a nationwide pandemic. These results are consistent with empirical influenza outbreak data. The results showed that simply scaling up a regional small-scale model is unlikely to account for all the complex variables and their interactions involved in a nationwide outbreak. There are several limitations of the methodology that should be explored in future

    Montoya, Ana; Cassone, Marco; Mody, Lona

    2016-08-01

    This review summarizes current literature pertaining to infection prevention in nursing home population including post-acute care patients and long-term care residents. Approximately 2 million infections occur each year and more than one-third of older adults harbor multidrug-resistant organisms in this setting. Surveillance, hand hygiene, isolation precautions, resident and employee health programs, education, and antibiotic stewardship are essential elements of infection prevention and control programs in nursing homes. This article discusses emerging evidence suggesting the usefulness of interactive multimodal bundles in reducing infections and antimicrobial resistance, thereby enhancing safety and quality of care for older adults in nursing homes.

    2011-01-01

    Full Text Available Abstract Background When investigating covariate interactions and group associations with standard regression analyses, the relationship between the response variable and exposure may be difficult to characterize. When the relationship is nonlinear, linear modeling techniques do not capture the nonlinear information content. Statistical learning (SL techniques with kernels are capable of addressing nonlinear problems without making parametric assumptions. However, these techniques do not produce findings relevant for epidemiologic interpretations. A simulated case-control study was used to contrast the information embedding characteristics and separation boundaries produced by a specific SL technique with logistic regression (LR modeling representing a parametric approach. The SL technique was comprised of a kernel mapping in combination with a perceptron neural network. Because the LR model has an important epidemiologic interpretation, the SL method was modified to produce the analogous interpretation and generate odds ratios for comparison. Results The SL approach is capable of generating odds ratios for main effects and risk factor interactions that better capture nonlinear relationships between exposure variables and outcome in comparison with LR. Conclusions The integration of SL methods in epidemiology may improve both the understanding and interpretation of complex exposure/disease relationships.

    2000-01-01

    Full Text Available Systematic investigation on the effects of human exposure to environmental pollution using scientific methodology only began in the 20th century as a consequence of several environmental accidents followed by an unexpected mortality increase above expected mortality and as a result of observational epidemiological and toxicological studies conducted on animals in developed countries. This article reports the experience of the Experimental Air Pollution Laboratory at the School of Medicine, University of São Paulo, concerning the respiratory system and pathophysiological mechanisms involved in responses to exposure to pollution using toxicological and experimental procedures, complemented by observational epidemiological studies conducted in the city of São Paulo. It also describes these epidemiological studies, pointing out that air pollution is harmful to public health, not only among susceptible groups but also in the general population, even when the concentration of pollutants is below the limits set by environmental legislation. The study provides valuable information to support the political and economic decision-making processes aimed at preserving the environment and enhancing quality of life.

    2010-01-01

    The NASA Applied Sciences Program works within NASA Earth sciences to leverage investment of satellite and information systems to increase the benefits to society through the widest practical use of NASA research results. Such observations provide a huge volume of valuable data in both near-real-time and extended back nearly 50 years about the Earth's land surface conditions such as land cover type, vegetation type and health, precipitation, snow, soil moisture, and water levels and radiation. Observations of this type combined with models and analysis enable satellite-based assessment of numerous water resources management activities. The primary goal of the Earth Science Applied Science Program is to improve future and current operational systems by infusing them with scientific knowledge of the Earth system gained through space-based observation, model results, and development and deployment of enabling technologies, systems, and capabilities. Water resources is one of eight elements in the Applied Sciences Program and it addresses concerns and decision making related to water quantity and water quality. With increasing population pressure and water usage coupled with climate variability and change, water issues are being reported by numerous groups as the most critical environmental problems facing us in the 21st century. Competitive uses and the prevalence of river basins and aquifers that extend across boundaries engender political tensions between communities, stakeholders and countries. Mitigating these conflicts and meeting water demands requires using existing resources more efficiently. The potential crises and conflicts arise when water is competed among multiple uses. For example, urban areas, environmental and recreational uses, agriculture, and energy production compete for scarce resources, not only in the Western U.S. but throughout much of the U.S. but also in many parts of the world. In addition to water availability issues, water quality related

    2013-01-01

    The Men in STD Training and Empowerment Research Study (MISTERS) program and epidemiological criminology began their development in Atlanta at about the same time. MISTERS focuses on men recently released from jail to reduce both HIV/STD and crime-related risk factors through a brief educational intervention. This article examines ways in which MISTERS and epidemiological criminology have been used to inform one another in the replication of the MISTERS program in Orange County, Florida. Data from 110 MISTERS participants during the first 10 months of operation are analyzed to examine the overlapping occurrence of health and criminal risk behaviors in the men's lives. This provides a test of core hypotheses from the epidemiological criminology framework. This article also examines application of the epidemiological criminology framework to develop interventions to address health and crime risk factors simultaneously in Criminal Justice-Involved populations in the community.

    The German federal states initiated the "Pathological Gambling and Epidemiology" (PAGE) program to evaluate the public health relevance of pathological gambling. The aim of PAGE was to estimate the prevalence of pathological gambling and cover the heterogenic presentation in the population with respect to comorbid substance use and mental disorders, risk and protective factors, course aspects, treatment utilization, triggering and maintenance factors of remission, and biological markers. This paper describes the methodological details of the study and reports basic prevalence data. Two sampling frames (landline and mobile telephone numbers) were used to generate a random sample from the general population consisting of 15,023 individuals (ages 14 to 64) completing a telephone interview. Additionally, high-risk populations have been approached in gambling locations, via media announcements, outpatient addiction services, debt counselors, probation assistants, self-help groups and specialized inpatient treatment facilities. The assessment included two steps: (1) a diagnostic interview comprising the gambling section of the Composite International Diagnostic Interview (CIDI) for case finding; (2) an in-depth clinical interview with participants reporting gambling problems. The in-depth clinical interview was completed by 594 participants, who were recruited from the general or high-risk populations. The program provides a rich epidemiological database which is available as a scientific use file.

    India is home to the world's second largest population. Rheumatology is an emerging specialty in India. We reviewed organization, epidemiology and training facilities for Rheumatology in India. Also, we also looked at publications in the field of rheumatology from India from over the past six years using Scopus and Medline databases. Despite rheumatologic disorders affecting 6%-24% of the population, rheumatology in India is still in its infancy. Till recently, there were as few as two centers in the country training less than five fellows per year. However, acute shortage of specialists and increasing patient numbers led to heightened awareness regarding the need to train rheumatologists. Subsequently, six new centers have now started 3-year training programs in rheumatology. The epidemiology of rheumatic diseases in India is being actively studies under the Community Oriented Programme for Control of Rheumatic Diseases (COPCORD) initiative. The most number of publications on rheumatic diseases from India are on rheumatoid arthritis, lupus and osteoporosis, many of which have been widely cited. Major collaborators worldwide are USA, UK and France, whereas those from Asia are Japan, Saudi Arabia and Singapore. The Indian Rheumatology Association (IRA) is the national organization of rheumatologists. The flagship publication of the IRA, the Indian Journal of Rheumatology, is indexed in Scopus and Embase. To conclude, rheumatology in India is an actively expanding and productive field with significant contributions to world literature. There is a need to train more personnel in the subject in India.

    2015-02-01

    Since the 1970s, the federal government has spearheaded major national education programs to reduce the burden of chronic diseases in the United States. These prevention and disease management programs communicate critical information to the public, those affected by the disease, and health care providers. The National Diabetes Education Program (NDEP), the leading federal program on diabetes sponsored by the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC), uses primary and secondary quantitative data and qualitative audience research to guide program planning and evaluation. Since 2006, the NDEP has filled the gaps in existing quantitative data sources by conducting its own population-based survey, the NDEP National Diabetes Survey (NNDS). The NNDS is conducted every 2–3 years and tracks changes in knowledge, attitudes and practice indicators in key target audiences. This article describes how the NDEP has used the NNDS as a key component of its evaluation framework and how it applies the survey results for strategic planning and program improvement. The NDEP's use of the NNDS illustrates how a program evaluation framework that includes periodic population-based surveys can serve as an evaluation model for similar national health education programs.

    In some communities, local government and non-profit entities have funds to purchase and renovate distressed, foreclosed homes for resale in the affordable housing market. Numerous opportunities to improve whole house energy efficiency are inherent in these comprehensive renovations. BA-PIRC worked together in a multiyear field study making recommendations in individual homes, meanwhile compiling improvement costs, projected energy savings, practical challenges, and labor force factors surrounding common energy-related renovation measures. The field study, Phase 1 of this research, resulted in a set of best practices appropriate to the current labor pool and market conditions in central Florida to achieve projected annual energy savings of 15%-30% and higher. This report describes Phase 2 of the work where researchers worked with a local government partner to implement and refine the "current best practices". A simulation study was conducted to characterize savings potential under three sets of conditions representing varying replacement needs for energy-related equipment and envelope components. The three scenarios apply readily to the general remodeling industry as for renovation of foreclosed homes for the affordable housing market. The new local government partner, the City of Melbourne, implemented the best practices in a community-scale renovation program that included ten homes in 2012.

  17. Epidemiologic aspects of neural tube defects in the United States: changing concepts and their importance for screening and prenatal diagnostic programs

    Energy Technology Data Exchange (ETDEWEB)

    Sever, L.E.; Strassburg, M.A.

    1983-09-01

    This report considers several major epidemiologic aspects of neural tube defects (NTDs). After examining briefly the approaches and goals of epidemiology the traditional epidemiologic concepts of NTDs are reviewed and new interpretations of the epidemiology of these defects is suggested. Three major topics are addressed: (1) that much of our knowledge of the epidemiology of the NTDs comes from areas or periods of high rates of occurrence and that generalizations based on these data may not be applicable to low incidence situations; (2) that the etiology of these defects is multifactorial, involving interaction between genetic and nongenetic factors which may differ in their relative importance between populations; and (3) that anencephalus and spina bifida may be more epidemiologically and etiologically distinct than is usually appreciated. A final consideration deals with some recent contributions of epidemiology to screening and prenatal diagnosis programs.

  18. Constraint-based scheduling applying constraint programming to scheduling problems

    CERN Document Server

    Baptiste, Philippe; Nuijten, Wim

    2001-01-01

    Constraint Programming is a problem-solving paradigm that establishes a clear distinction between two pivotal aspects of a problem: (1) a precise definition of the constraints that define the problem to be solved and (2) the algorithms and heuristics enabling the selection of decisions to solve the problem. It is because of these capabilities that Constraint Programming is increasingly being employed as a problem-solving tool to solve scheduling problems. Hence the development of Constraint-Based Scheduling as a field of study. The aim of this book is to provide an overview of the most widely used Constraint-Based Scheduling techniques. Following the principles of Constraint Programming, the book consists of three distinct parts: The first chapter introduces the basic principles of Constraint Programming and provides a model of the constraints that are the most often encountered in scheduling problems. Chapters 2, 3, 4, and 5 are focused on the propagation of resource constraints, which usually are responsibl...

  1. Applied Research of Enterprise Cost Control Based on Linear Programming

    Directory of Open Access Journals (Sweden)

    Yu Shuo

    2015-01-01

    This paper researches the enterprise cost control through the linear programming model, and analyzes the restriction factors of the labor of enterprise production, raw materials, processing equipment, sales price, and other factors affecting the enterprise income, so as to obtain an enterprise cost control model based on the linear programming. This model can calculate rational production mode in the case of limited resources, and acquire optimal enterprise income. The production guiding program and scheduling arrangement of the enterprise can be obtained through calculation results, so as to provide scientific and effective guidance for the enterprise production. This paper adds the sensitivity analysis in the linear programming model, so as to learn about the stability of the enterprise cost control model based on linear programming through the sensitivity analysis, and verify the rationality of the model, and indicate the direction for the enterprise cost control. The calculation results of the model can provide a certain reference for the enterprise planning in the market economy environment, which have strong reference and practical significance in terms of the enterprise cost control.

    Programmable logic controllers (PLCs) are embedded computers widely used in industrial control systems. Ensuring that a PLC software complies with its specification is a challenging task. Formal verification has become a recommended practice to ensure the correctness of safety-critical software but is still underused in industry due to the complexity of building and managing formal models of real applications. In this paper, we propose a general methodology to perform automated model checking of complex properties expressed in temporal logics (\\eg CTL, LTL) on PLC programs. This methodology is based on an intermediate model (IM), meant to transform PLC programs written in various standard languages (ST, SFC, etc.) to different modeling languages of verification tools. We present the syntax and semantics of the IM and the transformation rules of the ST and SFC languages to the nuXmv model checker passing through the intermediate model. Finally, two real cases studies of \\CERN PLC programs, written mainly in th...

  11. Applying dynamic programming to a gas-lift optimization problem

    Energy Technology Data Exchange (ETDEWEB)

    Camponogara, Eduardo; Nakashima, Paulo H.R. [Santa Catarina Univ., Florianopolis (Brazil). Dept. de Automacao e Sistemas]. E-mails: camponog@das.ufsc.br; phrn@das.ufsc.br

    2003-07-01

    The ever-increasing demand for nonrenewable resources and the pressure from stockholders are two forces pressing the oil industry for higher efficiency. The opportunities for advances abound in all sectors of the industry, in particular production processes in gas-lift oil wells, which are often favored to draw oil from high-depth reservoirs. Of concern in this paper is the task of distributing the limited supply of gas to the wells so as to induce an optimal oil production. Narrowing this task to the steady-state response of the wells gives rise to the gas-lift optimization problem, whose variables decide which wells should be active as well as the gas-injection and whose objective is profit maximization. The paper elaborates on a few properties of the problem and delivers a dynamic programming algorithm to find approximate solutions. The effectiveness of the algorithm was demonstrated by contrasting its solutions against upper bounds obtained with continuous relaxation. As closure, the paper outlines a few directions for future research. (author)

  12. Data Processing and Programming Applied to an Environmental Radioactivity Laboratory

    International Nuclear Information System (INIS)

    This report is the original research work presented for the attainment of the author master degree and its main objective has been the resolution -by means of friendly programming- of some of the observed problems in the environmental radioactivity laboratory belonging to the Department of Radiological Surveillance and Environmental Radioactivity from CIEMAT. The software has been developed in Visual Basic for applications in Excel files and it solves by macro orders three of the detected problems: a) calculation of characteristic limits for the measurements of the beta total and beta rest activity concentrations according to standards MARLAP, ISO and UNE and the comparison of the three results b) Pb-210 and Po-210 decontamination factor determination in the ultra-low level Am-241 analysis in air samples by alpha spectrometry and c) comparison of two analytical techniques for measuring Pb-210 in air ( direct-by gamma spectrometry- and indirect -by radiochemical separation and alpha spectrometry). The organization processes of the different excel files implied in the subroutines, calculations and required formulae are explained graphically for its comprehension. The advantage of using this kind of programmes is based on their versatility and the ease for obtaining data that lately are required by tables that can be modified as time goes by and the laboratory gets more data with the special applications for describing a method (Pb-210 decontamination factors for americium analysis in air) or comparing temporal series of Pb-210 data analysed by different methods (Pb-210 in air).

  13. The epidemiology of malignant giant cell tumors of bone: an analysis of data from the Surveillance, Epidemiology and End Results Program (1975–2004

    Directory of Open Access Journals (Sweden)

    Kendra Schwartz

    2009-12-01

    Full Text Available Malignant giant cell tumor (GCT of bone is a rare tumor with debilitating consequences. Patients with GCT of bone typically present with mechanical difficulty and pain as a result of bone destruction and are at an increased risk for fracture. Because of its unusual occurrence, little is known about the epidemiology of malignant GCT of bone. This report offers the first reliable population-based estimates of incidence, patient demographics, treatment course and survival for malignancy in GCT of bone in the United States. Using data from the National Cancer Institute’s Surveillance, Epidemiology and End Results (SEER program, we estimated the overall incidence and determinants of survival among patients diagnosed with malignant GCT of bone from 1975-2004. Cox proportional hazards regression was used to evaluate demographic and clinical determinants of survival among malignant GCT cases. Based on analyses of 117 malignant GCT cases, the estimated annual incidence in the United States was 1.6 per 10,000,000 persons per year. Incidence was highest among adults aged 20 to 44 years (2.4 per 10,000,000 per year and most patients were diagnosed with localized (31.6% or regional (29.9% disease compared to distant disease (16.2%. Approximately 85% of patients survived at least 5 years, with survival poorest among older patients and those with evidence of distant metastases at time of diagnosis. The current study represents the largest systematic investigation examining the occurrence and distribution of malignancy in GCT of bone in the general U.S. population. We confirm its rare occurrence and suggest that age and stage at diagnosis are strongly associated with long-term survival.

  14. An Applied Research Program on Water Desalination with Renewable Energies

    Directory of Open Access Journals (Sweden)

    S. M. Alcocer

    2008-01-01

    Full Text Available The use of renewable energy for desalination might be quite different in many places of the world. In Mexico, specifically in Baja California, there is an abundance of “traditional” renewable resources like sun and wind but also some others like hot springs at the coast, tidal currents and tidal amplitudes of over six meters in the upper part of the Gulf of California associated with a severe scarcity of fresh water. The National University of Mexico (UNAM started two years ago a well organized research program to assess the amount of these resources and to find the way to use them for desalinating sea water. Very exiting results have being obtained: The abundance of hot springs at the shore, some of them over 84°C, lead to the design of thermal desalinating prototype plants with very little energy consumption. It was found by geochemistry that at a few meters deep, some 50 m, very high temperature can be obtained, easy to use in binary geothermal power plants to generate electricity for desalination. During the survey it was found that the amount of electrical power that can be generated with tidal storage and from deep sea hydrothermal vents is of the order of several thousands of MW. A special approach is also presented for the use of solar energy and the tidal currents of the Gulf. The IMPULSA research group at UNAM has been already consolidated with more than 30 students, dedicated to the design of appropriate equipment to make use of these resources and to characterize and quantify this huge amount of renewable energies that will permit to desalinate sea water.

  13. Fuzzy goal programming applied to multi-objective programming problem with FREs as constraints

    Directory of Open Access Journals (Sweden)

    Kailash Lachhwani

    2015-09-01

    Full Text Available This paper presents an alternate technique based on fuzzy goal programming (FGP approach to solve multi-objective programming problem with fuzzy relational equations (FREs as constraints. The proposed technique is more efficient and requires less computational work than that of algorithm suggested by Jain and Lachhwani (2009 [Jain, & Lachhwani (2009. Multiobjective programming problem with fuzzy relational equations. International Journal of Operations Research, 6(2, 5563.]. In FGP formulation, objectives are transformed into the fuzzy goals using maximum and minimal solutions elements of FREs feasible solution set. A pseudo code computer algorithm is developed for computation of maximum solution of FREs. Suitable linear membership function is defined for each objective function. Then achievement of the highest membership value of each of the fuzzy goals is formulated by minimizing the sum of negative deviational variables. The aim of this paper is to present a simple and efficient solution procedure to obtain compromise optimal solution of multiobjective optimization problem with FREs as constraints. A comparative analysis is also carried out between two methodologies based on numerical examples.

    As of 2010 sub-Saharan Africa had approximately 865 million inhabitants living with numerous public health challenges. Several public health initiatives [e.g., the United States (US) President's Emergency Plan for AIDS Relief and the US President's Malaria Initiative] have been very successful at reducing mortality from priority diseases. A competently trained public health workforce that can operate multi-disease surveillance and response systems is necessary to build upon and sustain these successes and to address other public health problems. Sub-Saharan Africa appears to have weathered the recent global economic downturn remarkably well and its increasing middle class may soon demand stronger public health systems to protect communities. The Epidemic Intelligence Service (EIS) program of the US Centers for Disease Control and Prevention (CDC) has been the backbone of public health surveillance and response in the US during its 60 years of existence. EIS has been adapted internationally to create the Field Epidemiology Training Program (FETP) in several countries. In the 1990s CDC and the Rockefeller Foundation collaborated with the Uganda and Zimbabwe ministries of health and local universities to create 2-year Public Health Schools Without Walls (PHSWOWs) which were based on the FETP model. In 2004 the FETP model was further adapted to create the Field Epidemiology and Laboratory Training Program (FELTP) in Kenya to conduct joint competency-based training for field epidemiologists and public health laboratory scientists providing a master's degree to participants upon completion. The FELTP model has been implemented in several additional countries in sub-Saharan Africa. By the end of 2010 these 10 FELTPs and two PHSWOWs covered 613 million of the 865 million people in sub-Saharan Africa and had enrolled 743 public health professionals. We describe the process that we used to develop 10 FELTPs covering 15 countries in sub-Saharan Africa from 2004 to 2010 as a

    2014-12-01

    The SAGE program was initiated in 1983 to provide an applied geophysics research and education experience for students. Since 1983, 820 students have completed the SAGE summer program. Beginning in 1992, with funding from the NSF, SAGE has included an REU (Research Experience for Undergraduates) experience for selected undergraduate students from U.S. colleges and universities. Since 1992, 380 undergraduate REU students have completed the SAGE program. The four week, intensive, summer program is based in Santa Fe, New Mexico, and involves students in learning geophysical theory and applications; collection of geophysical field data in the northern Rio Grande Rift area; data processing, modeling and interpretation; and presentation (oral and written) of results of each student's research results. Students (undergraduates, graduates and professionals) and faculty are together on a school campus for the summer program. Successful strategies (developed over the years) of the program include teamwork experience, mentoring of REUs (by faculty and more senior students), cultural interchange due to students from many campuses across the U.S. and international graduate students, including industry visitors who work with the students and provide networking, a capstone experience of the summer program that includes all students making a "professional-meeting" style presentation of their research and submitting a written report, a follow-up workshop for the REU students to enhance and broaden their experience, and providing professional development for the REUs through oral or poster presentations and attendance at a professional meeting. Program challenges include obtaining funding from multiple sources; significant time investment in program management, reporting, and maintaining contact with our many funding sources and industry affiliates; and, despite significant efforts, limited success in recruiting racial and ethnic minority students to the program.

  7. Vaccine epidemiology: A review.

    Science.gov (United States)

    Lahariya, Chandrakant

    2016-01-01

    This review article outlines the key concepts in vaccine epidemiology, such as basic reproductive numbers, force of infection, vaccine efficacy and effectiveness, vaccine failure, herd immunity, herd effect, epidemiological shift, disease modeling, and describes the application of this knowledge both at program levels and in the practice by family physicians, epidemiologists, and pediatricians. A case has been made for increased knowledge and understanding of vaccine epidemiology among key stakeholders including policy makers, immunization program managers, public health experts, pediatricians, family physicians, and other experts/individuals involved in immunization service delivery. It has been argued that knowledge of vaccine epidemiology which is likely to benefit the society through contributions to the informed decision-making and improving vaccination coverage in the low and middle income countries (LMICs).

  9. The GNU Image Manipulation Program applied to study the sand dunes

    OpenAIRE

    Sparavigna, Amelia Carolina

    2013-01-01

    The study of sand dunes and their migration rates requires large length and time scales. Therefore, the use of time series of satellite images turns out to be important because it allows remote measure and control of the dunes. To obtain information from the satellite images we can use GIMP, the GNU Image Manipulation Program, which is freely available on the Web. Here we discuss some of its features and how they can be applied to study the sand dunes

    2015-12-01

    NASA ARSET http://arset.gsfc.nasa.gov has been providing applied remote sensing training since 2008. The goals of the program are to develop the technical and analytical skills necessary to utilize NASA resources for decision-support. The program has reached over 3500 participants, with 1600 stakeholders from 100 countries in 2015 alone. The target audience for the program are professionals engaged in environmental management in the public and private sectors, such as air quality forecasters, public utilities, water managers and non-governmental organizations engaged in conservation. Many program participants have little or no expertise in NASA remote sensing, and it's frequently their very first exposure to NASA's vast resources. One the key challenges for the program has been the evolution and refinement of its approach to communicating NASA data access, research, and ultimately its value to stakeholders. We discuss ARSET's best practices for sharing NASA science, which include 1) training ARSET staff and other NASA scientists on methods for science communication, 2) communicating the proper amount of scientific information at a level that is commensurate with the technical skills of program participants, 3) communicating the benefit of NASA resources to stakeholders, and 4) getting to know the audience and tailoring the message so that science information is conveyed within the context of agencies' unique environmental challenges.

    2009-07-01

    This paper describes an innovative evaluation model applied to TRANSPETRO's 'Marine Terminals Standardization Program' based on updating approaches of programs evaluation and organizational learning. Since the program was launched in 2004, the need for having an evaluation model able to evaluate its implementation progress, to measure the degree of standards compliance and its potential economic, social and environmental impacts has become evident. Within a vision of safe and environmentally responsible operations of marine terminals, this evaluation model was jointly designed by TRANSPETRO and PUC-Rio to promote continuous improvement and learning in operational practices and in the standardization process itself. TRANSPETRO believes that standardization supports its services and management innovation capability by creating objective and internationally recognized parameters, targets and metrology for its business activities. The conceptual model and application guidelines for this important tool are presented in this paper, as well as the next steps towards its implementation. (author)

    The Applied Meteorology Unit (AMU) provides technology development and transition services to improve operational weather support to America's space program . The AMU was founded in 1991 and operates under a triagency Memorandum of Understanding (MOU) between the National Aeronautics and Space Administration (NASA), the United States Air Force (USAF) and the National Weather Service (NWS) (Ernst and Merceret, 1995). It is colocated with the 45th Weather Squadron (45WS) at Cape Canaveral Air Force Station (CCAFS) and funded by the Space Shuttle Program . Its primary customers are the 45WS, the Spaceflight Meteorology Group (SMG) operated for NASA by the NWS at the Johnson Space Center (JSC) in Houston, TX, and the NWS forecast office in Melbourne, FL (MLB). The gap between research and operations is well known. All too frequently, the process of transitioning research to operations fails for various reasons. The mission of the AMU is in essence to bridge this gap for America's space program.

  14. Epidemiological methods: a brief review

    International Nuclear Information System (INIS)

    Epidemiology, the study of disease distributions in populations and the factors which influence these distributions, is an observational science, i.e., its data base consists of measurements made on free living individuals characterized by presence or absence of disease states and putative risk factors. Epidemiological studies are usually classified as descriptive or analytical. Descriptive studies are primarily used for planning and evaluating health programs or to generate etiological hypotheses. Analytical studies are primarily used for testing etiological hypotheses. Analytical studies are designed either as cohort investigations in which populations with and without a putative risk factor are followed through time to ascertain their differential incidence of disease, or case-control investigations in which the history of exposure to a putative risk factor is compared among persons with a disease and appropriate controls free of disease. Both descriptive and analytical epidemiological studies have been applied to health physics problems. Examples of such problems and the epidemiological methods used to explore them will be presented

    Full Text Available Introduction: Board scores are an important aspect of an emergency medicine (EM residency application. Residency directors use these standardized tests to objectively evaluate an applicant’s potential and help decide whether to interview a candidate. While allopathic (MD students take the United States Medical Licensing Examination (USMLE, osteopathic (DO students take the Comprehensive Osteopathic Medical Licensing Examination (COMLEX. It is difficult to compare these scores. Previous literature proposed an equation to predict USMLE based on COMLEX. Recent analyses suggested this may no longer be accurate. DO students applying to allopathic programs frequently ask whether they should take USMLE to overcome this potential disadvantage. The objective of the study is to compare the likelihood to match of DO applicants who reported USMLE to those who did not, and to clarify how important program directors consider it is whether or not an osteopathic applicant reported a USMLE score. Methods: We conducted a review of Electronic Residency Application Service (ERAS and National Resident Matching Program (NRMP data for 2010-2011 in conjunction with a survey of EM residency programs. We reviewed the number of allopathic and osteopathic applicants, the number of osteopathic applicants who reported a USMLE score, and the percentage of successful match. We compared the percentage of osteopathic applicants who reported a USMLE score who matched compared to those who did not report USMLE. We also surveyed allopathic EM residency programs to understand how important it is that osteopathic (DO students take USMLE. Results: There were 1,482 MD students ranked EM programs; 1,277 (86%, 95% CI 84.3-87.9 matched. There were 350 DO students ranked EM programs; 181 (52%, 95% CI 46.4-57.0 matched (difference=34%, 95% CI 29.8-39.0, p<0.0001. There were 208 DO students reported USMLE; 126 (61%, 95% CI 53.6-67.2 matched. 142 did not report USMLE; 55 (39%, 95% CI 30

  16. Optimization programs of radiation protection applied to post-graduation and encouraging research

    International Nuclear Information System (INIS)

    In 2011 we started the automation and integration of radiological protection optimization programs, in order to offer unified programs and inter-related information in Portuguese, providing Brazilian radioactive facilities a complete repository for research, consultation and information. The authors of this project extended it to postgraduate education, in order to encourage postgraduate students researches, expanding methods for enhancing student learning through the use of different combined resources, such as educational technology, information technology and group dynamics. This new methodology was applied in a postgraduate discipline at Instituto de Pesquisas Energeticas e Nucleares (IPEN), Brazil, in the postgraduate discipline entitled Fundamental Elements of Radiological Protection (TNA-5732). Students have six weeks to assimilate a complex content of optimization, considering national and international standards, guidelines and recommendations published by different organizations over the past decades. Unlike traditional classes, in which students receive prompt responses, this new methodology stimulates discussion, encouraging collective thinking processes and promoting ongoing personal reflection and researches. Case-oriented problem-solving permitted students to play different roles, promoting whole-group discussions and cooperative learning, approaching theory and practical applications. Students discussed different papers, published in international conferences, and their implications according to current standards. The automation of optimization programs was essential as a research tool during the course. The results of this experience were evaluated in two consecutive years. We had excellent results compared to the previous 14 years. The methodology has exceeded expectations and will be also applied in 2013 to ionizing radiation monitoring postgraduate classes. (author)

    At the request of the Cultural Union of the Upper Aniene Valley, the social-health workers dealing with school medicine of the Teaching District of Affile (Rome) have tried to define the programming lines for a health education intervention in the elementary schools of the district. The basic requisites of the intervention were pinpointed as: effectiveness, in terms of improvement of health conditions; short-term results; cognitive-transformative methodology having a spiral progression (cognitive, decision-making, implementative and of verification). The departure point of the intervention was the cognitive study on the social-health situation of the school population based on an analysis of the individual data contained in the medical files compiled by the school doctor, standardised and filled out with the pupils' social and family data. Out of 257 children, 212 were examined, namely 82.4% of the school population. The first social-anamnestic data on pupils' families was in respect of parents' level of education, giving the following results: 65% with elementary schooling only, 11% semi-illiterate and 10.5% diploma- or degree-holders. In respect of parents' working activities, on the other hand, a clear difference emerged: compared with 50.4% of worker or artisan fathers and about 33.3% engaged in the tertiary sector, almost all the mothers were still home-based (90.9% housewives). Another interesting fact emerged from the cards, namely that only 69% of the boys and girls have undergone the full cycle of antidiphtheria-antitetanus vaccinations, and only 80% of antipolio vaccinations. As regards pupils pathological anamnesis, cases of hospitalisation were for the following causes: 5.7% fractures and/or burns, followed by intestinal infections (4.5%). Whereas, as regards current pathology the high incidence of a cariogenic pathology emerged, with such high values as to indicate, in the field of prevention and health education, oral hygiene as the priority

    Full Text Available Introduction & Objective: Pupils have efficient potential to increase community awareness and promoting community health through participating in the health education programs. Child to family health education program is one of the communicative strategies that was applied in this field trial study. Because of high prevalence of Brucellosis in Hamadan province, Iran, the aim of this study was promoting families’ knowledge and preventive behaviors about Brucellosis in the rural areas by using child to family health education method.Materials & Methods: In this nonequivalent control group design study three rural schools were chosen (one as intervention and two others as control. At first knowledge and behavior of families about Brucellosis were determined using a designed questionnaire. Then the families were educated through “child to family” procedure. At this stage the students gained information. Then they were instructed to teach their parents what they had learned. After 3 months following the last session of education, the level of knowledge and behavior changes of the families about Brucellosis were determined and analyzed by paired t-test.Results: The results showed significant improvement in the knowledge of the mothers. The knowledge of the mothers about the signs of Brucellosis disease in human increased from 1.81 to 3.79 ( t:-21.64 , sig:0.000 , and also the knowledge on the signs of Brucellosis in animals increased from 1.48 to 2.82 ( t:-10.60 , sig:0.000. Conclusion: Child to family health education program is one of the effective and available methods, which would be useful and effective in most communities, and also Students potential would be effective for applying in the health promotion programs.

    Kolagani, Rajeswari

    It is a well-established fact that the scientific knowledge and skills acquired in the process of obtaining a degree in physics meet the needs of a variety of positions in multiple science and technology sectors. However, in addition to scientific competence, challenging careers often call for skills in advanced communication, leadership and team functions. The professional science master's degree, which has been nick-named as the `Science MBA', aims at providing science graduates an edge both in terms of employability and earning levels by imparting such skills. Our Professional Science Master's Program in Applied Physics is designed to develop these `plus' skills through multiple avenues. In addition to advanced courses in Applied Physics, the curriculum includes graduate courses in project management, business and technical writing, together with research and internship components. I will discuss our experience and lessons learned over the 5 years since the inception of the program in 2010.

    In this retrospective study of medical student data from Case Western Reserve University School of Medicine, we examined the impact of the Master of Science in Applied Anatomy (MS) program on medical student performance on the United States Medical Licensing Examination(®) (USMLE(®)) Step 1 and Step 2. From 2002 to 2010, 1,142 students matriculated as either students in the medical curriculum (MD group; 1,087 students) or MD students who also participated in the MS program (MD/MS group; 55 students). In addition, students were grouped as in either the Western Reserve Curriculum (2002-2005; WR1) or the Western Reserve 2 Curriculum (2006-2010; WR2). Data were analyzed using SPSS statistical package. The mean Medical College Admission Test(®) (MCAT(®)) score of all students increased significantly between the WR1 and WR2 curricula [from 32.48 ± 3.73 to 34.00 ± 2.92 (P USMLE Step 1 score for the MD/MS group (241.45 ± 18.90) was significantly higher than that of the MD group (229.93 ± 20.65; P USMLE Step 1 scores than the MD group. No significant difference was observed in the USMLE Step 2 Clinical Knowledge scores between the groups. The results show that MD/MS students performed better on the USMLE Step 1 than MD students in the WR2 curriculum, although MCAT scores were similar between the two groups. Together, these results suggest that medical student participation in the Masters in Applied Anatomy program enhances student performance on the USMLE Step 1.

    Captive breeding programs for wildlife species typically rely on pedigrees to inform genetic management. Although pedigree-based breeding strategies are quite effective at retaining long-term genetic variation, management of zoo-based breeding programs continues to be hampered when pedigrees are poorly known. The objective of this study was to evaluate 2 options for generating single nucleotide polymorphism (SNP) data to resolve unknown relationships within captive breeding programs. We generated SNP data for a zoo-based population of addax (Addax nasomasculatus) using both the Illumina BovineHD BeadChip and double digest restriction site-associated DNA (ddRAD) sequencing. Our results demonstrated that estimates of allele sharing (AS) between pairs of individuals exhibited low variances. Average AS variances were highest when using 50 loci (SNPchipall = 0.00159; ddRADall = 0.0249), but fell below 0.0003 for the SNP chip dataset when sampling ≥250 loci and below 0.0025 for the ddRAD dataset when sampling ≥500 loci. Furthermore, the correlation between the SNPchipall and ddRADall AS datasets was 0.88 (95%CI = 0.84-0.91) when subsampling 500 loci. Collectively, our results indicated that both SNP genotyping methods produced sufficient data for accurately estimating relationships, even within an extremely bottlenecked population. Our results also suggested that analytic assumptions historically integrated into the addax pedigree are not adversely impacting long-term pedigree-based management; kinships calculated from the analytic pedigree were significantly correlated (P < 0.001) with AS estimates. Overall, our conclusions are intended to serve as both a proof of concept and a model for applying molecular data to the genetic management of captive breeding programs. PMID:27208150

    Full Text Available The world is entering the era of recession when the trend is bearish and market is not so favorable. The capital markets in every major country were experiencing great amount of loss and people suffered in their investment. The Jakarta Composite Index (JCI has shown a great downturn for the past one year but the trend bearish year of the JCI. Therefore, rational investors should consider restructuring their portfolio to set bigger proportion in bonds and cash instead of stocks. Investors can apply modern portfolio theory by Harry Markowitz to find the optimum asset allocation for their portfolio. Higher return is always associated with higher risk. This study shows investors how to find out the lowest risk of a portfolio investment by providing them with several structures of portfolio weighting. By this way, investor can compare and make the decision based on risk-return consideration and opportunity cost as well. Keywords: Modern portfolio theory, Monte Carlo, linear programming

    Science.gov (United States)

    Utsumi, Noah; Yoshida, Masashi; Inada, Yuji

    One of the ways to mitigate global warming is to reduce carbon dioxide emissions. In Japan, carbon dioxide emissions from vehicles, which run on fossil fuels, account for about 1/4 of the total carbon dioxide emissions. In this study, we applied a commercial engine, and remodeled the engine which could work using bioethanol as a fuel. We subsequently examined the influence of exhaust emission of the engine with the bioethanol and documented the entire study as teaching materials, including the remodeling method. Next, we began our mechanical engineering courses at the university by using the teaching materials in this study as introductory education, with the aim of stimulating the interest of the students. We then developed an education program for the students.

  12. Stochastic Dynamic Programming Applied to Hydrothermal Power Systems Operation Planning Based on the Convex Hull Algorithm

    Directory of Open Access Journals (Sweden)

    Bruno H. Dias

    2010-01-01

    Full Text Available This paper presents a new approach for the expected cost-to-go functions modeling used in the stochastic dynamic programming (SDP algorithm. The SDP technique is applied to the long-term operation planning of electrical power systems. Using state space discretization, the Convex Hull algorithm is used for constructing a series of hyperplanes that composes a convex set. These planes represent a piecewise linear approximation for the expected cost-to-go functions. The mean operational costs for using the proposed methodology were compared with those from the deterministic dual dynamic problem in a case study, considering a single inflow scenario. This sensitivity analysis shows the convergence of both methods and is used to determine the minimum discretization level. Additionally, the applicability of the proposed methodology for two hydroplants in a cascade is demonstrated. With proper adaptations, this work can be extended to a complete hydrothermal system.

  13. Positive Mathematical Programming Approaches – Recent Developments in Literature and Applied Modelling

    Directory of Open Access Journals (Sweden)

    Thomas Heckelei

    2012-05-01

    Full Text Available This paper reviews and discusses the more recent literature and application of Positive Mathematical Programming in the context of agricultural supply models. Specifically, advances in the empirical foundation of parameter specifications as well as the economic rationalisation of PMP models – both criticized in earlier reviews – are investigated. Moreover, the paper provides an overview on a larger set of models with regular/repeated policy application that apply variants of PMP. Results show that most applications today avoid arbitrary parameter specifications and rely on exogenous information on supply responses to calibrate model parameters. However, only few approaches use multiple observations to estimate parameters, which is likely due to the still considerable technical challenges associated with it. Equally, we found only limited reflection on the behavioral or technological assumptions that could rationalise the PMP model structure while still keeping the model’s advantages.

    The NASA DEVELOP National Program takes a unique approach to cultivating the next generation of geoscientists through interdisciplinary research projects that address environmental and public policy issues through the application of NASA Earth observations. Competitively selected teams of students, recent graduates, and early career professionals take ownership of project proposals outlining basic application concepts and have ten weeks to research core scientific challenges, engage partners and end-users, demonstrate prototypical solutions, and finalize and document their results and outcomes. In this high pressure, results-driven environment emerging geoscience professionals build strong networks, hone effective communication skills, and learn how to call on the varied strengths of a multidisciplinary team to achieve difficult objectives. The DEVELOP approach to workforce development has a variety of advantages over classic apprenticeship-style internship systems. Foremost is the experiential learning of grappling with real-world applied science challenges as a primary actor instead of as an observer or minor player. DEVELOP participants gain experience that fosters personal strengths and service to others, promoting a balance of leadership and teamwork in order to successfully address community needs. The program also advances understanding of Earth science data and technology amongst participants and partner organizations to cultivate skills in managing schedules, risks and resources to best optimize outcomes. Individuals who come through the program gain experience and networking opportunities working within NASA and partner organizations that other internship and academic activities cannot replicate providing not only skill development but an introduction to future STEM-related career paths. With the competitive nature and growing societal role of science and technology in today's global community, DEVELOP fosters collaboration and advances environmental

    2012-01-01

    An innovative training program to provide clinical research training for clinicians was created in 1979 at the University of Pennsylvania School of Medicine, now the Perelman School of Medicine. The program's principal and continuing aim is to provide trainees mentored experiences and the training needed to become skilled independent investigators able to conduct clinical research and develop academic careers as independent clinical investigators.The authors identify the vision that led to the creation of the master of science in clinical epidemiology (MSCE) degree program and describe today's training program, including administration, oversight, participating faculty, and trainees. They also describe the program's core curriculum, elective options, seminars on ongoing research, training in the responsible conduct of research, professional development activities, and the development and completion of a closely mentored clinical research project.Approximately 35 new trainees enter the two- to three-year program annually. Funding is provided primarily by National Institutes of Health-funded training programs and supplemented by private industry, private foundations, and employee-based benefits. More than 500 individuals have received or are currently receiving training through the MSCE program. A large percentage of former trainees maintain full-time positions in academic medicine today.The authors identify some challenges that have been met and insights regarding funding, faculty, trainees, and curriculum. Ongoing challenges include recruiting trainees from some selected highly paid, procedure-oriented specialties, maintaining sufficient mentors for the continually increasing numbers of trainees, and distinguishing applicants who truly desire a primary research career from others.

  1. CEDR: Comprehensive Epidemiologic Data Resource

    Energy Technology Data Exchange (ETDEWEB)

    1993-08-01

    The Department of Energy (DOE) and its predecessor agencies have a long history of epidemiologic research programs. The main focus of these programs has been the Health and Mortality Study of the DOE work force. This epidemiologic study began in 1964 with a feasibility study of workers at the Hanford facility. Studies of other populations exposed to radiation have also been supported, including the classic epidemiologic study of radium dial painters and studies of atomic bomb survivors. From a scientific perspective, these epidemiologic research program have been productive, highly credible, and formed the bases for many radiological protection standards. Recently, there has been concern that, although research results were available, the data on which these results were based were not easily obtained by interested investigators outside DOE. Therefore, as part of an effort to integrate and broaden access to its epidemiologic information, the DOE has developed the Comprehensive Epidemiologic Data Resource (CEDR) Program. Included in this effort is the development of a computer information system for accessing the collection of CEDR data and its related descriptive information. The epidemiologic data currently available through the CEDAR Program consist of analytic data sets, working data sets, and their associated documentation files. In general, data sets are the result of epidemiologic studies that have been conducted on various groups of workers at different DOE facilities during the past 30 years.

    2014-01-01

    Epidemiology is the study of disease distribution and factors determining or affecting it. Likewise, endodontic epidemiology can be defined as the science of studying the distribution pattern and determinants of pulp and periapical diseases; specially apical periodontitis. Although different study designs have been used in endodontics, researchers must pay more attention to study designs with higher level of evidence such as randomized clinical trials.

  4. Applying Best Practices to Florida Local Government Retrofit Programs, Central Florida (Fact Sheet)

    Energy Technology Data Exchange (ETDEWEB)

    2014-03-01

    In some communities, local government and non-profit entities have funds to purchase and renovate distressed, foreclosed homes for resale in the affordable housing market. Numerous opportunities to improve whole house energy efficiency are inherent in these comprehensive renovations. BA-PIRC worked together in a multi-year field study making recommendations in individual homes, meanwhile compiling improvement costs, projected energy savings, practical challenges, and labor force factors surrounding common energy-related renovation measures. The field study, Phase 1 of this research, resulted in a set of best practices appropriate to the current labor pool and market conditions in central Florida to achieve projected annual energy savings of 15-30% and higher. This report describes Phase 2 of the work where researchers worked with a local government partner to implement and refine the "current best practices". A simulation study was conducted to characterize savings potential under three sets of conditions representing varying replacement needs for energy-related equipment and envelope components. The three scenarios apply readily to the general remodeling industry as for renovation of foreclosed homes for the affordable housing market. Our new local government partner, the City of Melbourne, implemented the best practices in a community-scale renovation program that included ten homes in 2012. ​

    2013-12-01

    During the summer of 2013, the Cascadia Initiative Expedition Team led six oceanographic expeditions to recover and redeploy ocean bottom seismometers (OBSs) across the Cascadia subduction zone and Juan de Fuca plate. The Cascadia Initiative (CI) is an onshore/offshore seismic and geodetic experiment to study questions ranging from megathrust earthquakes to volcanic arc structure to the formation, deformation and hydration of the Juan de Fuca and Gorda plates with the overarching goal of understanding the entire subduction zone system. The Cascadia Initiative Expedition Team is a team of scientists charged with leading the oceanographic expeditions to deploy and recover CI OBSs and developing the associated Education and Outreach effort. Students and early career scientists were encouraged to apply to join the cruises via the Cascadia Initiative Expedition Team's Apply to Sail Program. The goal of this call for open participation was to help expand the user base of OBS data by providing opportunities for students and scientists to directly experience at-sea acquisition of OBS data. Participants were required to have a strong interest in learning field techniques, be willing to work long hours at sea assisting in OBS deployment, recovery and preliminary data processing and have an interest in working with the data collected. In total, there were 51 applicants to the Apply to Sail Program from the US and 4 other countries; 21 graduate students as well as a few undergraduate students, postdocs and young scientists from the US and Canada were chosen to join the crew. The cruises lasted from 6 to 14 days in length. OBS retrievals comprised the three first legs, of which the first two were aboard the Research Vessel Oceanus. During each of the retrievals, multiple acoustic signals were sent while the vessel completed a semi-circle around the OBS to accurately determine its position, a final signal was sent to drop the seismometer's anchor, and finally the ship and crew

    Salman, M D

    2009-12-01

    The effectiveness of detection and control of highly contagious animal diseases is dependent on a solid understanding of their nature and implementation of scientifically sound methods by people who are well trained. The implementation of specific detection methods and tools requires training and application in natural as well as field conditions. The aim of this paper is to present the design and implementation of training in disease investigation and basic veterinary epidemiology in selected countries using the Highly Pathogenic Avian Influenza (HPAI) H5N1 Asia strain as a disease detection model. Indonesia, Egypt, Nigeria, Turkey, and Vietnam were each identified as either a priority country where AI was spreading rapidly or a country at risk for infection. In each of these countries, a training program on epidemiological concepts, field investigation methodology, and detection of H5N1 Asia strain cases was conducted. This report includes the impact of these training sessions on national animal health programs, including follow-up activities of animal health officers who went through these training sessions.

    NASA's Applied Remote Sensing Training Program (ARSET), http://arset.gsfc.nasa.gov, has been providing applied remote sensing training since 2008. To date, the program has reached over 3500 participants, with 1600 stakeholders from 100 countries in 2015 alone. The goals of the program are to develop the technical and analytical skills necessary to utilize NASA resources for decision-support, and to help end-users navigate through the vast, freely available and open data resources. We discuss ARSET's best practices and training approach to improved data access and application of NASA satellite and model data for air quality, water resources, disasters, land, and wildfire management. ARSET follows an iterative approach where the end user community is engaged and data needs input is solicited throughout the training process. End-user data needs and feedback are also incorporated into current and future training content and communicated to NASA Applied Sciences Program principal investigators and data centers responsible for developing NASA tools, portals, data formats, and other data delivery structures. ARSET's success has relied upon 1) targeting outreach to applied science professionals both as training participants and collaborators in developing training activities 2) developing training content tailored to a specific to community's decision support activities and unique environmental challenges 3) promoting interactive forums during trainings to capture and assess end-user needs 4) training scientists within the program in science communication 5) adopting a contextualized gradual learning approach through online and hands-on instruction, and 6) conducting program evaluation, used to assess the benefit of ARSET to program participants and to plan and adapt future training content, methods, and outreach activities.

In 2001, The Carter Center and the United States Institute for Peace sponsored a conference within which "Violence and Health" was discussed and a working group on applied epidemiology formed. The group was tasked to describe the skills that are essential to effective functioning in these settings and thereby provide guidance to the applied epidemiology training programs. Methods We conducted a literature review and consultation of a convenience sample of practitioners of applied epidemiology with experience in conflict areas. Results and conclusions The health programs designed to prevent and mitigate conflict are in their early stages of implementation and the evaluation measures for success are still being defined. The practice of epidemiology in conflict must occur within a larger humanitarian and political context to be effective. The skills required extend beyond the normal epidemiological training that focuses on the valid collection and interpretation of data and fall into two general categories: (1 Conducting a thorough assessment of the conflict setting in order to design more effective public health action in conflict settings, and (2 Communicating effectively to guide health program implementation, to advocate for needed policy changes and to facilitate interagency coordination. These are described and illustrated using examples from different countries.

  13. Paratingent Derivative Applied to the Measure of the Sensitivity in Multiobjective Differential Programming

    2013-01-01

    Full Text Available We analyse the sensitivity of differential programs of the form subject to where and are maps whose respective images lie in ordered Banach spaces. Following previous works on multiobjective programming, the notion of -optimal solution is used. The behaviour of some nonsingleton sets of -optimal solutions according to changes of the parameter in the problem is analysed. The main result of the work states that the sensitivity of the program is measured by a Lagrange multiplier plus a projection of its derivative. This sensitivity is measured by means of the paratingent derivative.

  14. Object Oriented Mutation Applied in Java Application programming Interface and C++ Classes

    Directory of Open Access Journals (Sweden)

    Mr. Titu Singh Arora

    2011-09-01

    Full Text Available Mutation analysis is a powerful and computationally expensive technique that measures the effectiveness of test cases for revealing faults. The principal expense of mutation analysis is that many faulty versions of the program under test, culled mutants, must be repeatedly executed. We survey several aspects of reconstruction of complex object-oriented faults on the java API. Application of object-oriented mutation operators in java programs using a parser-based tool can be precise but requires compilation of mutants. In this paper we approach the mutation on Object Oriented features to test the functionality. For this we consider java and C++ programs.

  16. Relevant aspects of a quality assurance program applied to a nuclear power plant operation

    International Nuclear Information System (INIS)

    The purpose of this work was to enumerate the most relevant subjects to be taken into account for the elaboration of a Quality Assurance Program aimed to regulate a nuclear power plant operation. At first, it was necessary to point out the relevance that implies the presence of a group of personnel, experienced in quality assurance with enough knowledge on the technical and organizing aspects of the plant. Other aspect to be taken into account was the contemplation of the international requirements, through the International Atomic Energy Agency and of the national requirements that each country had set up by the corresponding regulating agencies. These organizations pointed out the minimum rules that must be followed for the adequate and efficient execution of a program. The Quality Assurance Manual and the program and work procedures constituted the Quality Assurance Program which must be checked as regards its fulfillment by auditors and quality assurance supervisions.

  1. APPLYING ROBUST RANKING METHOD IN TWO PHASE FUZZY OPTIMIZATION LINEAR PROGRAMMING PROBLEMS (FOLPP

    Directory of Open Access Journals (Sweden)

    Monalisha Pattnaik

    2014-12-01

    Full Text Available Background: This paper explores the solutions to the fuzzy optimization linear program problems (FOLPP where some parameters are fuzzy numbers. In practice, there are many problems in which all decision parameters are fuzzy numbers, and such problems are usually solved by either probabilistic programming or multi-objective programming methods. Methods: In this paper, using the concept of comparison of fuzzy numbers, a very effective method is introduced for solving these problems. This paper extends linear programming based problem in fuzzy environment. With the problem assumptions, the optimal solution can still be theoretically solved using the two phase simplex based method in fuzzy environment. To handle the fuzzy decision variables can be initially generated and then solved and improved sequentially using the fuzzy decision approach by introducing robust ranking technique. Results and conclusions: The model is illustrated with an application and a post optimal analysis approach is obtained. The proposed procedure was programmed with MATLAB (R2009a version software for plotting the four dimensional slice diagram to the application. Finally, numerical example is presented to illustrate the effectiveness of the theoretical results, and to gain additional managerial insights. 

  2. Epidemiological causality.

    Science.gov (United States)

    Morabia, Alfredo

    2005-01-01

    Epidemiological methods, which combine population thinking and group comparisons, can primarily identify causes of disease in populations. There is therefore a tension between our intuitive notion of a cause, which we want to be deterministic and invariant at the individual level, and the epidemiological notion of causes, which are invariant only at the population level. Epidemiologists have given heretofore a pragmatic solution to this tension. Causal inference in epidemiology consists in checking the logical coherence of a causality statement and determining whether what has been found grossly contradicts what we think we already know: how strong is the association? Is there a dose-response relationship? Does the cause precede the effect? Is the effect biologically plausible? Etc. This approach to causal inference can be traced back to the English philosophers David Hume and John Stuart Mill. On the other hand, the mode of establishing causality, devised by Jakob Henle and Robert Koch, which has been fruitful in bacteriology, requires that in every instance the effect invariably follows the cause (e.g., inoculation of Koch bacillus and tuberculosis). This is incompatible with epidemiological causality which has to deal with probabilistic effects (e.g., smoking and lung cancer), and is therefore invariant only for the population.

  3. Cost-Benefit Analysis applied to the natural gas program for vehicles in the Metropolitan Area of the Aburra Valley

    International Nuclear Information System (INIS)

    This article presents the evaluation of the natural gas program for vehicles applied in Metropolitan Area of the Aburra Valley. By using the Cost- Benefit Analysis method, four cost variables were identified: private, fiscal, gas tax, and conversion tax; and three types of benefits: private, fiscal and social. For the environmental social benefit estimation the benefit transfer technique was employed, carrying out meta-analysis function estimation. The cost-benefit net outcome is positive and favors the program application in the study site; in real terms the total profits are about COP$ 803265 million for the complete eight year period it took place (2001- 2008).

    Divorce proportions are currently high in the US and they are even higher among those who are incarcerated with substance abuse problems. Although much research has examined marital interventions, only two studies have examined marital interventions with prison populations. There is some empirical evidence that incarcerated couples benefit from traditional marital therapy (O'Farrell and Fals-Stewart, 1999, Addictions: A comprehensive guidebook, New York, Oxford University Press). An adaptation of the evidence-based Creating Lasting Family Connections program was implemented with 144 married couples, where one spouse was incarcerated, in a southern state with particularly high divorce and incarceration proportions. Results suggested that married men exposed to the program had larger improvements in some relationship skills relative to a convenience sample of men not so exposed. Both husbands and wives exposed to the program exhibited similar and significant increases in relationship skills. The results were comparable to a Prevention and Relationship Enhancement Program adaptation for inmates. The implications of the findings for prevention practitioners are discussed.

    2010-12-01

    This paper describes the interaction of four elements of social science as they have evolved in concert with the Center for Adaptive Optics Professional Development Program (CfAO PDP). We hope these examples persuade early-career scientists and engineers to include social science activities as they develop grant proposals and carry out their research. To frame our discussion we use a metaphor from astronomy. At the University of California Santa Cruz (UCSC), the CfAO PDP and the Educational Partnership Center (EPC) are two young stars in the process of forming a solar system. Together, they are surrounded by a disk of gas and dust made up of program evaluation, applied research, educational assessment, and pedagogy. An idea from the 2001 PDP intensive workshops program evaluation developed into the Assessing Scientific Inquiry and Leadership Skills (AScILS) applied research project. In iterative cycles, AScILS researchers participated in subsequent PDP intensive workshops, teaching social science while piloting AScILS measurement strategies. Subsequent "orbits" of the PDP program evaluation gathered ideas from the applied research and pedagogy. The denser regions of this disk of social science are in the process of forming new protoplanets as tools for research and teaching are developed. These tools include problem-solving exercises or simulations of adaptive optics explanations and scientific reasoning; rubrics to evaluate the scientific reasoning simulation responses, knowledge regarding inclusive science education, and student explanations of science/engineering inquiry investigations; and a scientific reasoning curriculum. Another applied research project is forming with the design of a study regarding how to assess engineering explanations. To illustrate the mutual shaping of the cross-disciplinary, intergenerational group of educational researchers and their projects, the paper ends with a description of the professional trajectories of some of the

    Lanier, Mark M; Pack, Robert P; Akers, Timothy A

    2010-01-01

    Epidemiological methods and public health theories can be tied to theories of crime and delinquency and used to create evidence-based policy. Interdisciplinary theoretical approaches to existing, and emerging, public health and criminal justice problems hold great promise. Differential association theory postulates that close association with delinquent peers leads to an increase in deviant activities such as illicit drug use. Social cognitive theory postulates that health behavior change is driven by the interaction of (a) cognitive states that support a health outcome, (b) the social and contextual environment, (c) and individual action. Combined, these theories can be applied to drug eradication programs as well as other health and crime issues. Focus groups and interviews were performed to identify rates of illicit substance use among incarcerated African American adolescent male gang members and nongang members. The policy recommendations illustrate the convergence of criminological and epidemiological theory under the new paradigm of epidemiological criminology or ''EpiCrim.''

  19. An introduction to geographic information systems as applied to a groundwater remediation program

    International Nuclear Information System (INIS)

    While the attention to environmental issues has grown over the past several years, so has the focus on groundwater protection. Addressing the task of groundwater remediation often involves a large-scale program with numerous wells and enormous amounts of data. This data must be manipulated and analyzed in an efficient manner for the remediation program to be truly effective. Geographic Information System's (GIS) have proven to be an extremely effective tool in handling and interpreting this type of groundwater information. The purpose of this paper is to introduce the audience to GIS technology, describe how it is being used at the Savannah River Site (SRS) to handle groundwater data and demonstrate how it may be used in the corporate Westinghouse environment

  1. PCARRD's strategies for technology transfer: The agriculture and resources regional technology information system and the regional applied communication program

    International Nuclear Information System (INIS)

    This paper describes the Agriculture and Resources Regional Technology Information System (ARRTIS) and the Regional Applied Communication Outreach Program (RAC) of PCARRD. The ARRTIS and the RACO are the strategies in communicating scientific and technology-based information. The ARRTIS is an information system that provides an information base on the status of technologies at various levels of maturity (generation, adaptation, verification, piloting, dissemination and utilization) and offers technology alternatives based on environmental requirements, costs and returns analysis or feasibility of the technologies. This information base provides the repository of technology information from which the Applied Communication Program draws its information for packaging into various formats, using various strategies/media to cater to various users in the regions most especially the farmers. Meanwhile, as PCARRD executes its mission of developing the national research system, it incorporates a development support communication program through the RACO. The RACO is essentially a working component of a regional research center/consortium in each region coordinated by the Applied Communication Division of PCARRD. It aims at reaching farmers and their families, extensionists, administrators, policy makers and entrepreneurs with research information and technology which use a variety of appropriate communication channels, modern communication technology and strategies so that they may actively participate in research diffusion and utilization.

    2015-11-01

    Full Text Available Background: The role of pain education is well established in improving knowledge and attitude towards the adherence to pain assessment and management. Methods: A brief pain education program was delivered to assess nurses' knowledge and attitude towards pain assessment and management. The "KASRP" scale was used at three phases; pre, post, and three months' follow-up phases. Subsequent eight months observation on using pain assessment sheets was also performed. Results: One hundred and four nurses were assessed at the beginning, followed by 92 at the immediate post-test, and 70 at the follow-up. Although nurses scored lowest in having knowledge and attitudes prior to the program, a significant improvement was evident after delivering pain education. In addition, nurses' competency in pain assessment was maintained over the three months of assessment. Younger nurses with shorter clinical experience were found more reactive to the program than older nurses. Conclusions: A brief nurse-driven pain education has improved nurses' knowledge and attitude towards pain management.

    The programmatic, technical, user application, and cost factors associated with the development of an operational, statewide land use inventory from LANDSAT data are described. The LANDSAT multispectral data are subjected to geometrical and categorical processing to produce map files for each of the 200 fifteen (15) minute quads covering Ohio. Computer compatible tapes are rescanned to produce inventory tapes which identify eight (8) Level I land use categories and a variety of Level II categories. The inventory tapes are processed through a series of ten (10) software programs developed by the State of Ohio. The net result is a computerized inventory which can be displayed in map or tabular form for various geographic units, at a variety of scales and for selected categories of usage. The computerized inventory data files are applied to technical programs developed by the various state agencies to be used in state, regional, and local planning programs.

    Coronary artery disease (CAD) is a worldwide leading cause of death. The standard method for evaluating critical partial occlusions is coronary arteriography, a catheterization technique which is invasive, time consuming, and costly. There are noninvasive approaches for the early detection of CAD. The basis for the noninvasive diagnosis of CAD has been laid in a sequential analysis of the risk factors, and the results of the treadmill test and myocardial perfusion scintigraphy (MPS). Many investigators have demonstrated that the diagnostic applications of MPS are appropriate for patients who have an intermediate likelihood of disease. Although this information is useful, it is only partially utilized in clinical practice due to the difficulty to properly classify the patients. Since the seminal work of Lotfi Zadeh, fuzzy logic has been applied in numerous areas. In the present study, we proposed and tested a model to select patients for MPS based on fuzzy sets theory. A group of 1053 patients was used to develop the model and another group of 1045 patients was used to test it. Receiver operating characteristic curves were used to compare the performance of the fuzzy model against expert physician opinions, and showed that the performance of the fuzzy model was equal or superior to that of the physicians. Therefore, we conclude that the fuzzy model could be a useful tool to assist the general practitioner in the selection of patients for MPS. (author)

    Training and capacity building are long established critical components of global water, sanitation, and hygiene (WaSH) policies, strategies, and programs. Expanding capacity building support for WaSH in developing countries is one of the targets of the Sustainable Development Goals. There are many training evaluation methods and tools available. However, training evaluations in WaSH have been infrequent, have often not utilized these methods and tools, and have lacked rigor. We developed a conceptual framework for evaluating training in WaSH by reviewing and adapting concepts from literature. Our framework includes three target outcomes: learning, individual performance, and improved programming; and two sets of influences: trainee and context factors. We applied the framework to evaluate a seven-month community-led total sanitation (CLTS) management training program delivered to 42 government officials in Kenya from September 2013 to May 2014. Trainees were given a pre-training questionnaire and were interviewed at two weeks and seven months after initial training. We qualitatively analyzed the data using our conceptual framework. The training program resulted in trainees learning the CLTS process and new skills, and improving their individual performance through application of advocacy, partnership, and supervision soft skills. The link from trainees' performance to improved programming was constrained by resource limitations and pre-existing rigidity of trainees' organizations. Training-over-time enhanced outcomes and enabled trainees to overcome constraints in their work. Training in soft skills is relevant to managing public health programs beyond WaSH. We make recommendations on how training programs can be targeted and adapted to improve outcomes. Our conceptual framework can be used as a tool both for planning and evaluating training programs in WaSH.

    GU Hai-bo; LU Yan-sheng

    2008-01-01

    A unit testing approach for AspectJ programs is proposed to separately test aspect units which have their own states. In the approach, aspects under test are converted to classes before execution of unit testing. In the conversion process, the context information passed through pointcut is transformed into advices, then the advices are converted to class member methods, and conflicts in the conversion result, if any, are resolved finally. The unit testing process consists of generating test cases, executing test cases and checking results.

  11. Applying an innovative educational program for the education of today's engineers

    International Nuclear Information System (INIS)

    Engineers require a broad spectrum of knowledge and skills: basic skills in mathematics and physics, skills and competencies within the major subject area as well as more general knowledge about business and enterprise contexts, society regulations and understanding of the future professions' characteristics. In addition, social, intercultural, analytical and managing competencies are desired. The CDIO educational program was initiated as a means to come closer to practice and to assure the training of engineering skills that are required of today's engineers. CDIO is short for Conceive-Design-Implement-Operate and describes the full life cycle understanding of a system or asset that engineering students should reach during education. The CDIO initiative is formulated in a program consisting of two important documents: the CDIO standards and the CDIO syllabus. The standards describe a holistic approach on education, from knowledge and skills to be trained, how to train and assess them, to how to develop the teaching staff and the work places for enabling the goals. The specific knowledge and skills to be achieved are accounted for in the syllabus. In this paper we share our more than 15 years of experiences in problem and project based learning from the perspective of the CDIO standards. For each standard, examples of how to set up the education and overcome challenges connected to the standard are given. The paper concludes with recommendations to others wishing to work toward problem and real-life based education without compromising the requirements of a scientific approach.

    1989-01-01

    Optimization procedures are developed to systematically provide closely-spaced vibration frequencies. A general purpose finite-element program for eigenvalue and sensitivity analyses is combined with formal mathematical programming techniques. Results are presented for three studies. The first study uses a simple model to obtain a design with two pairs of closely-spaced frequencies. Two formulations are developed: an objective function-based formulation and constraint-based formulation for the frequency spacing. It is found that conflicting goals are handled better by a constraint-based formulation. The second study uses a detailed model to obtain a design with one pair of closely-spaced frequencies while satisfying requirements on local member frequencies and manufacturing tolerances. Two formulations are developed. Both the constraint-based and the objective function-based formulations perform reasonably well and converge to the same results. However, no feasible design solution exists which satisfies all design requirements for the choices of design variables and the upper and lower design variable values used. More design freedom is needed to achieve a fully satisfactory design. The third study is part of a redesign activity in which a detailed model is used.

    Caudullo, Giovanni

    2014-01-01

    Bioclimate-driven regression analysis is a widely used approach for modelling ecological niches and zonation. Although the bioclimatic complexity of the European continent is high, a particular combination of 12 climatic and topographic covariates was recently found able to reliably reproduce the ecological zoning of the Food and Agriculture Organization of the United Nations (FAO) for forest resources assessment at pan-European scale, generating the first fuzzy similarity map of FAO ecozones in Europe. The reproducible procedure followed to derive this collection of bioclimatic indices is now presented. It required an integration of data-transformation modules (D-TM) using geospatial tools such as Geographic Information System (GIS) software, and array-based mathematical implementation such as semantic array programming (SemAP). Base variables, intermediate and final covariates are described and semantically defined by providing the workflow of D-TMs and the mathematical formulation following the SemAP notat...

  16. Product traceability and quality as applied to the united states transuranic and high-level waste repository programs

    International Nuclear Information System (INIS)

    As with any repository program, predictions of the performance of a site over very long time frames may often meet with skepticism from the public and decision-makers, such as regulatory and governmental agencies. Experience at the WIPP and the YMP indicate that demonstrating the defensibility of data, conceptual models, computer codes, and numerical analyses is critical. Five overarching principles have been found to be the basis of a technically and publicly acceptable repository. The principles are traceability, transparency, reproducibility, retrievability, and reviews. - Traceability allows one to understand the source and justification of data and other input that generate conclusions. - Transparency allows one to follow the logic, calculations, and other operations that produce results. - Reproducibility allows one to reconstruct the results without recourse to the originator of the information. - Retrievability allows one to retrieve documentation that demonstrate these overarching principles. - Reviews ensure that the work is technically acceptable, complete, and accurate. This paper discusses how these principles are applied to the WIPP and the YMP. By setting up quality assurance and management controls (e.g., procedures, audits, peer reviews) these principles are implemented. Without successfully applying these principles the WIPP would not have gone from research to industrial maturity. The YMP is ensuring that these are implemented for activities that support licensing. Any repository program concerned with demonstrating defensibility to the public and regulators would do well by incorporating traceability, transparency, reproducibility, retrievability, and reviews into their program.

    Flowers, Alice Blood

    Lack of personal connection to the natural world by most American youth builds reason for assessing effectiveness of conservation education programs. Place-based learning is important in helping youth understand how their personal and societal well-being are linked and dependent upon their local habitats. Across Montana 2277 students in grades 3--10 participate in an interactive year long fishing education program with their teachers called Hooked on Fishing (HOF). The purpose of my study was to assess the effectiveness of HOF, a place-based conservation education program established in 1996, and modeled after the national Hooked on Fishing, Not on Drugs program. Using a quasi-experimental nonequivalent group study design, students received a pre-survey during the beginning of the program, a post-survey after the program, and an extended post-survey 12 to 14 weeks later. Teachers voluntarily participated in an Internet survey during May 2006, and program instructors voluntarily participated in a structured open-ended telephone interview in June 2006. A key component of my study was the decision to conduct the evaluation process using an approach which included stakeholders in the development of the instruments to measure student outcomes. This approach is called utilization-focused evaluation and was developed by Michael Q. Patton. The motive of this approach is to promote the usability of the evaluation results. The results are considered to have a better chance to be applied by the program stakeholders to not only gauge program effectiveness, but to be used to improve the program. Two research questions were: (1) does the frequency of outdoor experiences have significant affects on students' knowledge, skills, attitudes, and intended stewardship behaviors; and (2) does improved knowledge of local natural resources have significant affects on students' skills, attitudes and intended stewardship behavior. Nonparametric statistical analyses calculated statistical

    Two decades ago, the Emerging Infections Program of the US Centers for Disease Control and Prevention implemented what seemed like a simple yet novel idea: a population- and laboratory-based surveillance system designed to identify and characterize invasive bacterial infections, including those caused by Streptococcus pneumoniae. This system, known as Active Bacterial Core surveillance, has since served as a flexible platform for following trends in invasive pneumococcal disease and studying vaccination as the most effective method for prevention. We report the contributions of Active Bacterial Core surveillance to every pneumococcal vaccine policy decision in the United States during the past 20 years. PMID:26291238

  19. Integrated Demonstration program -- Applying innovative technologies to VOC remediation in arid environments

    International Nuclear Information System (INIS)

    Historical activities at US DOE facilities around the United States during World War II, including development of a nuclear deterrent, resulted in the discharge of chemical and radioactive materials to the environment. The DOE has now focused a major technical effort on the mitigation of the effects of those discharges through an environmental restoration program. The DOE Office of Technology Development (OTD) launched a major initiative to develop and demonstrate more cost-effective and safer means of restoring contaminated areas. This initiative integrates available conventional technologies and innovative and/or emerging technologies with ongoing environmental restoration activities. The ultimate goal of the OTD initiative is to have demonstrated technologies available for commercial application when they are needed at DOE sites. A key element of the initiative is the creation of Integrated Demonstrations (IDs). The VOC Arid-ID is providing the mechanism for developing and deploying cradle-to-grave technical solutions using a creative approach for solving environmental cleanup problems at the Hanford site. Within the last 10 months, and from it's inception, the ID has been successful in deploying demonstrated technologies from monitoring and characterization through site remediation. The creation of IDs has provided DOE with a mechanism to accelerate the Hanford site cleanup by bringing technology forward in a timely manner to meet the needs of the stakeholders

    To demonstrate the relevance of activity-based cost management (ABCM) for the occupational and environmental health community, the investigators used data generated by an ABCM model of a respiratory protection program (RPP) to develop options for solving a business problem. The RPP manager in this hypothetical but realistic business scenario is faced with a 25% budget cut and a 10% increase in demand for RPP services. The manager's dilemma is to maintain the integrity of the RPP while absorbing a significant budget cut. Various cost savings options are developed, and the assumptions under which these options operate are presented. It is emphasized that the RPP manager's primary responsibility is to assure worker health and safety by first understanding the technical issues, merits, and implications of any cost-cutting option that may be considered. It is argued that only then should the manager consider the financial merits of the possible solutions to this business problem. In this way worker health and safety, and environmental protection goals, can continue to be achieved in an economic climate of cost cutting and downsizing. PMID:9622907

    2015-12-01

    Full Text Available This article presents a mathematical model for barge transport planning on the river Rhine, which is part of a decision support system (DSS recently taken into use by the Swiss company Omya. The system is operated by Omya’s regional office in Cologne, Germany, responsible for distribution planning at the regional distribution center (RDC in Moerdijk, the Netherlands. The distribution planning is a vital part of supply chain management of Omya’s production of Norwegian high quality calcium carbonate slurry, supplied to European paper manufacturers. The DSS operates within a vendor managed inventory (VMI setting, where the customer inventories are monitored by Omya, who decides upon the refilling days and quantities delivered by barges. The barge planning problem falls into the category of inventory routing problems (IRP and is further characterized with multiple products, heterogeneous fleet with availability restrictions (the fleet is owned by third party, vehicle compartments, dependency of barge capacity on water-level, multiple customer visits, bounded customer inventories and rolling planning horizon. There are additional modelling details which had to be considered to make it possible to employ the model in practice at a sufficient level of detail. To the best of our knowledge, we have not been able to find similar models covering all these aspects in barge planning. This article presents the developed mixed-integer programming model and discusses practical experience with its solution. Briefly, it also puts the model into the context of the entire business case of value chain optimization in Omya.

  2. Optimal design of pre-fermentation and fermentation stages applying nonlinear programming

    International Nuclear Information System (INIS)

    Highlights: • Simultaneous synthesis, design and operation of fermentation networks are addressed. • A superstructure NLP model is presented. • Ethanol production from molasses and hydrolyzed sugar cane bagasse is proposed. • Different tradeoffs between design and operating variables can be evaluated. - Abstract: In the present work, the optimal design of pre-fermentation and fermentation operations for ethanol production is obtained developing a superstructure mathematical model. Different configurations of both operations are simultaneously considered in an overall model which also includes detailed kinetics equations. The zero wait is the transfer policy selected for these stages for ensuring the quality of these operations, given the nature and characteristics of microbiological sugary substrates. From the overall proposed model, the optimal configuration of the stages, the number of duplicated units in each stage, the size of each process unit, the process variables as concentrations and flows, and the total investment and production cost are obtained. This model is formulated as a non-linear programming problem, which is solved by the Professional Software, General Algebraic Modeling System (GAMS) with the application of CONOPT solver. The optimal design and operation of pre-fermentation and fermentation stages are obtained and the attained results are compared with the structures in conventional distillery

    This report is one of a set of three documents that have collectively identified and recommended research and development capabilities that will be required to advance nuclear energy in the next 20 to 50 years. The first report, Nuclear Energy for the Future: Required Research and Development Capabilities—An Industry Perspective, was produced by Battelle Memorial Institute at the request of the Assistant Secretary of Nuclear Energy. That report, drawn from input by industry, academia, and Department of Energy laboratories, can be found in Appendix 5.1. This Idaho National Laboratory report maps the nuclear-specific capabilities from the Battelle report onto facility requirements, identifying options from the set of national laboratory, university, industry, and international facilities. It also identifies significant gaps in the required facility capabilities. The third document, Executive Recommendations for Nuclear R&D Capabilities, is a letter report containing a set of recommendations made by a team of senior executives representing nuclear vendors, utilities, academia, and the national laboratories (at Battelle’s request). That third report can be found in Appendix 5.2. The three reports should be considered as set in order to have a more complete picture. The basis of this report was drawn from three sources: previous Department of Energy reports, workshops and committee meetings, and expert opinion. The facilities discussed were winnowed from several hundred facilities that had previously been catalogued and several additional facilities that had been overlooked in past exercises. The scope of this report is limited to commercial nuclear energy and those things the federal government, or more specifically the Office of Nuclear Energy, should do to support its expanded deployment in order to increase energy security and reduce carbon emissions. In the context of this report, capabilities mean innovative, well-structured research and development programs

    2015-01-01

    A hepatitis A+B vaccine vaccination program of 12-year-olds was introduced in Catalonia in 1998. The aim of this study was to investigate the evolution of hepatitis A outbreaks in Catalonia and estimate the preventable fraction of cases associated with outbreaks as a measure of the impact of the vaccination program. Hepatitis A outbreaks reported to the Health Department between 1991 and 2012 were analyzed. The incidence rates of outbreaks, outbreak-associated cases and hospitalizations were calculated. The preventable fraction (PF) and 95% confidence intervals (CI) were estimated for the whole study period (pre-vaccination and post-vaccination) and the post-vaccination period.   One-hundred-eight (108) outbreaks (rate of 2.21 per 10(6) persons-year) were reported in the pre-vaccination period and 258 outbreaks (rate of 2.82 per 10(6) persons-year) in the post-vaccination period. The rate of cases associated with outbreaks was 1.52 per 10(5) persons-year in the pre-vaccination period and 1.28 per 10(5) persons-year in the post-vaccination period. Hospitalization rates were 0.08 and 0.75 per 10(6) persons-year, respectively. The number of person-to-person outbreaks whose index case was a school contact decreased in the post-vaccination period (aOR 2.72; 95%CI 1.35-5.48), but outbreaks whose index case was a man who has sex with men (MSM) or an immigrant increased. The PF of all outbreak-associated cases was 6.46% (95%CI 3.11-9.82) and the highest PF was in the 15-24 years age group (42.53%; 95%CI 29.30-55.75). In the 0-4 years age group, the PF was 18.35% (95%CI 9.59-27.11), suggesting a protective herd effect in unvaccinated subjects. Vaccination of immigrants traveling to endemic countries and MSM should be reinforced.

    Liquefied natural gas (LNG) is the most economical way of transporting natural gas (NG) over long distances. Liq-uefaction of NG using vapor compression refrigeration system requires high operating and capital cost. Due to lack of systematic design methods for multistage refrigeration cycles, conventional approaches to determine op-timal cycle are largely trial-and-error. In this paper a novel mixed integer non-linear programming (MINLP) model is introduced to select optimal synthesis of refrigeration systems to reduce both operating and capital costs of an LNG plant. Better conceptual understanding of design improvement is illustrated on composite curve (CC) and exergetic grand composite curve (EGCC) of pinch analysis diagrams. In this method a superstruc-ture representation of complex refrigeration system is developed to select and optimize key decision variables in refrigeration cycles (i.e. partition temperature, compression configuration, refrigeration features, refrigerant flow rate and economic trade-off). Based on this method a program (LNG-Pro) is developed which integrates VBA, Refprop and Excel MINLP Solver to automate the methodology. Design procedure is applied on a sample LNG plant to illustrate advantages of using this method which shows a 3.3% reduction in total shaft work consumption.

    Full Text Available Ranking fuzzy numbers has become an important process in decision making. Many ranking methods have been proposed thus far and one of the commonly used is centroid of trapezoid. Here we try to derive detail mathematical derivation of centroids of a Trapezoidal Intuitionistic Fuzzy Number along x and y axis. After that we derive the ranking value from two centroid along x and y axis. At the end of the article ranking value on fuzzy geometric programming is used. Here we are dealing with three strong decision making concepts. Intuitionistic trapezoidal fuzzy system is much more decision oriented approach than normal fuzzy number in real life uncertain environment, where we can apply membership and non membership concept for analyzing any real life situation. Ranking value, based on centroid of any Trapezoidal Intuitionistic Fuzzy Number helps for conclusion derivation in quantitative way. We here choose most powerful non linear optimization tool, geometrical programming technique, for generating any decision, using Trapezoidal Intuitionistic Fuzzy Number with centroid ranking approach.

    2009-04-01

    Full Text Available The Aim and Significance of the Research: The characteristics that lecturers wish students applying for post-graduate programs should possess are determined in this paper quantitatively through pairwise comparisons according to the lecturers' responses.  The fact that resources and studies concerning the issue of scaling are scarcely available has been the most significant driving force for researchers to conduct research on this issue. It is believed that this research will make contributions to the field of scaling, which has limited number of studies. Since this research is a work of scaling which is rarely seen in the field of education, it is thought that the research is significant. Method of Research: The research was conducted on the 129 lecturers working in the different departments of Hacettepe University in the fall and spring semesters in the 2006 - 2007 academic year. At the stage of preparing the tool of measurement, the 7 characteristics that were required students should possess for selection to post-graduate education programs were determined and a tool of measurement through which pairwise comparisons would be made were designed.  Consequently, the scale value for each characteristic was marked on the line of numbers. Findings and Comments: According to the pairwise comparison, academic achievement score is in the first order. This is followed by the score gained in the interview, the purpose in entering the department, their level of English proficiency, ALES score, whether or not they are originally the students of the department and whether or not they have a letter of reference, respectively. According to results, when the students are selected to the post-graduate education programs it is suggested that the weighting of the students' characteristics required is made by considering this order. In addition to this, it is thought that studying with different samples and different scaling methods provide important

    Bovine tuberculosis (bTB), caused by Mycobacterium bovis (M. bovis), is a serious re-emerging disease in both animals and humans. The evolution of the Multi- and Extensively drug-resistant M. bovis strains (MDR-TB and XDR-TB) represents a global threat to public health. Worldwide, the disease is responsible for great economic losses in the veterinary field, serious threat to the ecosystem, and about 3.1% of human TB cases, up to 16% in Tanzania. Only thorough investigation to understand the pathogen's epidemiology can help in controlling the disease and minimizing its threat. For this purpose, various tools have been developed for use in advanced molecular epidemiological studies of bTB, either alone or in combination with standard conventional epidemiological approaches. These techniques enable the analysis of the intra- and inter-species transmission dynamics of bTB. The delivered data can reveal detailed insights into the source of infection, correlations among human and bovine isolates, strain diversity and evolution, spread, geographical localization, host preference, tracing of certain virulence factors such as antibiotic resistance genes, and finally the risk factors for the maintenance and spread of M. bovis. They also allow for the determination of epidemic and endemic strains. This, in turn, has a significant diagnostic impact and helps in vaccine development for bTB eradication programs. The present review discusses many topics including the aetiology, epidemiology and importance of M. bovis, the prevalence of bTB in humans and animals in various countries, the molecular epidemiology of M. bovis, and finally applied molecular epidemiological techniques.

    2016-04-01

    Full Text Available Background: Over time, Residency Match dynamics fluctuate with some specialties experiencing increases in medical student popularity. Academic departments with limited resources must devise methods for coping with increased demand for their specialty. Students perceive traditional programs on Match mechanics as inadequate. Subsequently, faculty are confronted with demands for more personal attention from more students. Objectives: We developed a strategy for providing specialty-specific residency match advising to large numbers of students. Methods: The ‘speed-advising’ session (SAS was developed to address the common questions and concerns that medical students pose during the Match process and to provide advisees with a breadth of faculty perspectives. Two SASs were offered over a 2-week period. After the sessions, students and faculty were surveyed regarding their experience. Results: Twenty-six students pursued our specialty in the 2015 Match (26 of 234, 11.1%. Twenty-three (89% participated in the SAS. Seventy-four percent of students (17 of 23 and all faculty completed the post-session survey. Students found the SAS to be informative, helpful and an efficient use of time. Common discussion topics included: career goals, to which programs and how many to apply, and how academic record impacts their likelihood of matching in our specialty. Students would have preferred more time with each faculty; however, most (77% conceded that their questions were adequately answered.

    Background Over time, Residency Match dynamics fluctuate with some specialties experiencing increases in medical student popularity. Academic departments with limited resources must devise methods for coping with increased demand for their specialty. Students perceive traditional programs on Match mechanics as inadequate. Subsequently, faculty are confronted with demands for more personal attention from more students. Objectives We developed a strategy for providing specialty-specific residency match advising to large numbers of students. Methods The ‘speed-advising’ session (SAS) was developed to address the common questions and concerns that medical students pose during the Match process and to provide advisees with a breadth of faculty perspectives. Two SASs were offered over a 2-week period. After the sessions, students and faculty were surveyed regarding their experience. Results Twenty-six students pursued our specialty in the 2015 Match (26 of 234, 11.1%). Twenty-three (89%) participated in the SAS. Seventy-four percent of students (17 of 23) and all faculty completed the post-session survey. Students found the SAS to be informative, helpful and an efficient use of time. Common discussion topics included: career goals, to which programs and how many to apply, and how academic record impacts their likelihood of matching in our specialty. Students would have preferred more time with each faculty; however, most (77%) conceded that their questions were adequately answered. Faculty-favored speed advising over traditional advising (86%), primarily due to estimated time savings of 7.3 h per faculty member. Conclusions In preparing students for the Match, specialty-specific speed advising offers an efficient supplement to traditional advising. PMID:27056564

    Within the NASA DEVELOP National Program, teams conduct rapid prototype and feasibility projects, applying NASA Earth Observations to a broad range of problems in diverse focus areas, including water resources, agriculture, disaster management, and ecological forecasting, with the goal of assisting partner organizations in their decision making processes. Projects vary in scope, design, and satellite data utilized. As a result, there is no "fixed" set of indicators that encompasses all relevant impacts of all projects. Rather, a flexible toolkit of both shared indicators and individualized approaches is needed to capture the diverse outcomes of these projects, while still allowing for comparability of the projects. This has been done through the creation of pre- and post-project partner assessments that capture partner needs, capabilities, and expectations. This provides both baseline data and an overview of project impacts on partners. Selected projects are then individually assessed in greater detail through partner follow-ups and research into the quantification of project impacts utilizing interdisciplinary approaches to fit each project. This process is discussed through three examples of project impact assessments that draw from varied discipline approaches including cost benefit analysis and ecosystem services.

    In some communities, local government and non-profit entities have funds to purchase and renovate distressed, foreclosed homes for resale in the affordable housing market. Numerous opportunities to improve whole house energy efficiency are inherent in these comprehensive renovations. BA-PIRC worked together in a multiyear field study making recommendations in individual homes, meanwhile compiling improvement costs, projected energy savings, practical challenges, and labor force factors surrounding common energy-related renovation measures. The field study, Phase 1 of this research, resulted in a set of best practices appropriate to the current labor pool and market conditions in central Florida to achieve projected annual energy savings of 15%-30% and higher. This case study describes Phase 2 of the work where researchers worked with a local government partner to implement and refine the "current best practices". A simulation study was conducted to characterize savings potential under three sets of conditions representing varying replacement needs for energy-related equipment and envelope components. The three scenarios apply readily to the general remodeling industry as for renovation of foreclosed homes for the affordable housing market. The new local government partner, the City of Melbourne, implemented the best practices in a community-scale renovation program that included ten homes in 2012.

    Trichinosis is one of the most common food-borne parasitic zoonoses in Thailand and many outbreaks are reported each year. This paper reviews the history, species,and epidemiology of the disease and food habits of the people with an emphasis on the north, northeast, central and south regions of Thailand. The earliest record of trichinosis in Thailand was in 1962 in the Mae Sariang District, Mae Hong Son Province. Since then, about 130 outbreaks have been reported involving 7392 patients and 97 deaths (1962-2005). The highest number of cases, 557, was recorded in 1983. The annual epidemiological surveillance reports of the Bureau of Epidemiology,Department of Disease Control, Ministry of Public Health,Thailand, show that trichinosis cases increased from 61 in 1997 to 351 in 1998.In contrast to these figures, the number of reported cases decreased to 16 in 1999 and 128 cases in 2000. There was no record of trichinosis in 2001, but then the figures for 2002, 2003 and 2004 were 289, 126 and 212 respectively. The infected patients were mostly in the 35-44 years age group and the disease occurred more frequently in men than women at a ratio of 1.7-2.0:1. There were 84 reported cases of trichinosis in Chiang Rai, Nan, Chiang Mai, Si Sa ket,Nakhon Phanom, Kalasin, Nakhon Ratchasima, Nakhon Nayok, Nakhon Pathom and Surat Thani, provinces located in different parts of Thailand in 2005. The outbreaks were more common in the northern areas, especially in rural areas where people ate raw or under-cooked pork and/or wild animals. This indicates the need for health education programs to prevent and control trichinosis as soon as possible in the high-risk areas.

  4. Evaluation of diagnostic tools for epidemiological purposes: Application to FMD

    International Nuclear Information System (INIS)

    Full text: Foot-and-mouth disease (FMD) is economically the most important disease of domestic livestock. Due to its highly infectious nature, ability to cause persistent infection and long-term effects on the animal species it affects, countries that have the disease have many trade restrictions placed upon them. The importance of laboratory information is critical for FMD control and eradication programs. In this regard and in support of the Continental Program for Eradication of FMD, implemented in 1988 in the Americas, a major challenge for the Pan American Foot-and-Mouth Disease Center (PAFMDC) as a regional OIE reference laboratory, was related to the adaptation of approaches to respond to the new demands of diagnostic precision placed to support the epidemiological transition expected in the Continent. Regions with advanced eradication campaigns needed to incorporate approaches for rapid and precise identification of the agent during an emergency, and equally important, for enabling a deeper epidemiological analysis, capable of characterizing the potential sources of infection and dissemination of the virus, either during clinical or subclinical viral circulation. Since the implementation of the eradication program there have been significant advances in the understanding of FMD epidemiology in South America. These have partly been due to the application of nucleotide sequencing methods for viral characterization and of newly developed tools for sero epidemiological monitoring of persistent viral activity, based on the use of recombinant noncapsideal antigens as serological probes to detect infection specific antibodies, regardless of vaccination condition. In the PAFMDC, a genetic sequence database of representative South American strains has been built up, which constituted the basis for the phylogenetic analysis of the viruses type O and A, responsible for the major outbreaks recorded, in regions already declared free by the OIE in the Southern Cone of

    A Principal Components Analysis (PCA) has been written to aid in the interpretation of multivariate aerial radiometric data collected by the US Department of Energy (DOE) under the National Uranium Resource Evaluation (NURE) program. The variations exhibited by these data have been reduced and classified into a number of linear combinations by using the PCA program. The PCA program then generates histograms and outlier maps of the individual variates. Black and white plots can be made on a Calcomp plotter by the application of follow-up programs. All programs referred to in this guide were written for a DEC-10. From this analysis a geologist may begin to interpret the data structure. Insight into geological processes underlying the data may be obtained.

    Epidemiology is a foundation of all clinical and public health research and practice. Epidemiology serves seven important uses for the advancement of medicine and public health. It enables community diagnosis by quantifying risk factors and diseases in the community; completes the clinical picture of disease by revealing the entire distribution of disease and presenting meaningful population averages from representative samples; identifies risk factors for disease by detecting and quantifying associations between exposures and disease and evaluating causal hypotheses; computes individual risk to identify high-risk groups to whom preventive interventions can be targeted; evaluates historic trends that monitor disease over time and provide clues to etiology; delineates new syndromes and disease subtypes not previously apparent in clinical settings, helping to streamline effective disease management; and investigates the effects of health services on population health to identify effective public health interventions. The clinician with a grasp of epidemiologic principles is in a position to critically evaluate the research literature, to apply it to clinical practice, and to undertake valid clinical epidemiology research with patients in clinical settings.

    1974-01-01

    This report presents the derivation, description, and operating instructions for a computer program (TEKVAL) which measures the economic value of advanced technology features applied to long range commercial passenger aircraft. The program consists of three modules; and airplane sizing routine, a direct operating cost routine, and an airline return-on-investment routine. These modules are linked such that they may be operated sequentially or individually, with one routine generating the input for the next or with the option of externally specifying the input for either of the economic routines. A very simple airplane sizing technique was previously developed, based on the Brequet range equation. For this program, that sizing technique has been greatly expanded and combined with the formerly separate DOC and ROI programs to produce TEKVAL.

    Full Text Available Abstract Background The transfer and implementation of acceptable and effective health services, programs and innovations across settings provides an important and potentially cost-effective strategy for reducing Indigenous Australians' high burden of disease. This study reports a systematic review of Indigenous health services, programs and innovations to examine the extent to which studies considered processes of transfer and implementation within and across Indigenous communities and healthcare settings. Methods Medline, Informit, Infotrac, Blackwells Publishing, Proquest, Taylor and Francis, JStor, and the Indigenous HealthInfoNet were searched using terms: Aborigin* OR Indigen* OR Torres AND health AND service OR program* OR intervention AND Australia to locate publications from 1992–2011. The reference lists of 19 reviews were also checked. Data from peer reviewed journals, reports, and websites were included. The 95% confidence intervals (95% CI for proportions that referred to and focussed on transfer were calculated as exact binomial confidence intervals. Test comparisons between proportions were calculated using Fisher's exact test with an alpha level of 5%. Results Of 1311 publications identified, 119 (9.1%; 95% CI: 7.6% - 10.8% referred to the transfer and implementation of Indigenous Australian health services or programs, but only 21 studies (1.6%; 95% CI: 1.0% - 2.4% actually focused on transfer and implementation. Of the 119 transfer studies, 37 (31.1%; 95% CI: 22.9 - 40.2% evaluated the impact of a service or program, 28 (23.5%; 95% CI: 16.2% - 32.2% reported only process measures and 54 were descriptive. Of the 37 impact evaluation studies, 28 (75.7%; 95% CI: 58.8% - 88.2% appeared in peer reviewed journals but none included experimental designs. Conclusion While services and programs are being transferred and implemented, few studies focus on the process by which this occurred or the effectiveness of the service or program

  13. Linking healthcare associated norovirus outbreaks: a molecular epidemiologic method for investigating transmission

    Directory of Open Access Journals (Sweden)

    Andrews Nick

    2006-07-01

    Full Text Available Abstract Background Noroviruses are highly infectious pathogens that cause gastroenteritis in the community and in semi-closed institutions such as hospitals. During outbreaks, multiple units within a hospital are often affected, and a major question for control programs is: are the affected units part of the same outbreak or are they unrelated transmission events? In practice, investigators often assume a transmission link based on epidemiological observations, rather than a systematic approach to tracing transmission. Here, we present a combined molecular and statistical method for assessing: 1 whether observed clusters provide evidence of local transmission and 2 the probability that anecdotally|linked outbreaks truly shared a transmission event. Methods 76 healthcare associated outbreaks were observed in an active and prospective surveillance scheme of 15 hospitals in the county of Avon, England from April 2002 to March 2003. Viral RNA from 64 out of 76 specimens from distinct outbreaks was amplified by reverse transcription-PCR and was sequenced in the polymerase (ORF 1 and capsid (ORF 2 regions. The genetic diversity, at the nucleotide level, was analysed in relation to the epidemiological patterns. Results Two out of four genetic and epidemiological clusters of outbreaks were unlikely to have occurred by chance alone, thus suggesting local transmission. There was anecdotal epidemiological evidence of a transmission link among 5 outbreaks pairs. By combining this epidemiological observation with viral sequence data, the evidence of a link remained convincing in 3 of these pairs. These results are sensitive to prior beliefs of the strength of epidemiological evidence especially when the outbreak strains are common in the background population. Conclusion The evidence suggests that transmission between hospitals units does occur. Using the proposed criteria, certain hypothesized transmission links between outbreaks were supported while

    2011-08-01

    Full Text Available INTRODUCTION: The case definition of influenza-like illness (ILI is a powerful epidemiological tool during influenza epidemics. METHODS: A prospective cohort study was conducted to evaluate the impact of two definitions used as epidemiological tools, in adults and children, during the influenza A H1N1 epidemic. Patients were included if they had upper respiratory samples tested for influenza by real-time reverse transcriptase polymerase chain reaction during two periods, using the ILI definition (coughing + temperature > 38ºC in period 1, and the definition of severe acute respiratory infection (ARS (coughing + temperature > 38ºC and dyspnoea in period 2. RESULTS: The study included 366 adults and 147 children, covering 243 cases of ILI and 270 cases of ARS. Laboratory confirmed cases of influenza were higher in adults (50% than in children (21.6% ( p < 0.0001 and influenza infection was more prevalent in the ILI definition (53% than ARS (24.4% (p < 0.0001. Adults reported more chills and myalgia than children (p = 0.0001. Oseltamivir was administered in 58% and 46% of adults and children with influenza A H1N1, respectively. The influenza A H1N1 case fatality rate was 7% in adults and 8.3% in children. The mean time from onset of illness until antiviral administration was 4 days. CONCLUSIONS: The modification of ILI to ARS definition resulted in less accuracy in influenza diagnosis and did not improve the appropriate time and use of antiviral medication.

    2004-05-01

    Mass segmentation plays a crucial role in computer-aided diagnosis (CAD) systems for classification of suspicious regions as normal, benign, or malignant. In this article we present a robust and automated segmentation technique--based on dynamic programming--to segment mass lesions from surrounding tissue. In addition, we propose an efficient algorithm to guarantee resulting contours to be closed. The segmentation method based on dynamic programming was quantitatively compared with two other automated segmentation methods (region growing and the discrete contour model) on a dataset of 1210 masses. For each mass an overlap criterion was calculated to determine the similarity with manual segmentation. The mean overlap percentage for dynamic programming was 0.69, for the other two methods 0.60 and 0.59, respectively. The difference in overlap percentage was statistically significant. To study the influence of the segmentation method on the performance of a CAD system two additional experiments were carried out. The first experiment studied the detection performance of the CAD system for the different segmentation methods. Free-response receiver operating characteristics analysis showed that the detection performance was nearly identical for the three segmentation methods. In the second experiment the ability of the classifier to discriminate between malignant and benign lesions was studied. For region based evaluation the area Az under the receiver operating characteristics curve was 0.74 for dynamic programming, 0.72 for the discrete contour model, and 0.67 for region growing. The difference in Az values obtained by the dynamic programming method and region growing was statistically significant. The differences between other methods were not significant.

    The allocation of a significant amount of new funding for health promotion in Australia through the National Partnership Agreement on Preventive Health (2009-14) created a unique opportunity to implement a comprehensive approach to the prevention of chronic diseases and demonstrate significant health improvements. Building on existing health promotion infrastructure in Local Health Districts, the NSW Ministry of Health adopted a scaled-up state-wide capacity-building model, designed to alter policies and practices in key children's settings to increase healthy eating and physical activity among children. NSW also introduced a performance monitoring framework to track implementation and impacts. This paper describes the model that NSW developed for monitoring state-wide programs in the Children's Healthy Eating and Physical Activity Program and presents the model's application to early childhood education and care and primary school settings, including current results. This approach to monitoring the scaling up of program implementation at the state-wide level has potential for more widespread application in other policy areas in NSW. PMID:25828447

    The NASA DEVELOP National Program conducts over eighty Earth science projects every year. Each project applies NASA Earth observations to impact decision-making related to a local or regional community concern. Small, interdisciplinary teams create a methodology to address the specific issue, and then pass on the results to partner organizations, as well as providing them with instruction to continue using remote sensing for future decisions. Many different methods are used by individual teams, and the program as a whole, to communicate results and research accomplishments to decision-makers, stakeholders, alumni, and the general public. These methods vary in scope from formal publications to more informal venues, such as social media. This presentation will highlight the communication techniques used by the DEVELOP program. Audiences, strategies, and outlets will be discussed, including a newsletter, microjournal, video contest, and several others.

    1998-06-01

    The US Department of Energy established a geopressured-geothermal energy program in the mid 1970`s as one response to America`s need to develop alternate energy resources in view of the increasing dependence on imported fossil fuel energy. This program continued for 17 years and approximately two hundred million dollars were expended for various types of research and well testing to thoroughly investigate this alternative energy source. This volume describes the following studies: Geopressured-geothermal hybrid cycle power plant: design, testing, and operation summary; Feasibility of hydraulic energy recovery from geopressured-geothermal resources: economic analysis of the Pelton turbine; Brine production as an exploration tool for water drive gas reservoirs; Study of supercritical Rankine cycles; Application of the geopressured-geothermal resource to pyrolytic conversion or decomposition/detoxification processes; Conclusions on wet air oxidation, pyrolytic conversion, decomposition/detoxification process; Co-location of medium to heavy oil reservoirs with geopressured-geothermal resources and the feasibility of oil recovery using geopressured-geothermal fluids; Economic analysis; Application of geopressured-geothermal resources to direct uses; Industrial consortium for the utilization of the geopressured-geothermal resource; Power generation; Industrial desalination, gas use and sales, pollutant removal, thermal EOR, sulfur frasching, oil and natural gas pipelining, coal desulfurization and preparation, lumber and concrete products kilning; Agriculture and aquaculture applications; Paper and cane sugar industries; Chemical processing; Environmental considerations for geopressured-geothermal development. 27 figs., 25 tabs.

    We analyzed data from 18 898 adults (age ≥20 years) and 2836 children/adolescents reported in the Surveillance, Epidemiology and End Results (SEER) database as having Hodgkin lymphoma (HL), diagnosed from 1988 to 2005. The nodular sclerosis subtype was significantly more common in the pediatric age group (76% in children/adolescents vs. 61% in adults, p < 0.001). The mixed cellularity subtype was more prevalent in children <10 years old (22%), but less likely in older children/adolescents (8.5%). Systemic symptoms were reported in 39% of children/adolescents and in 48% of adults (p < 0.001). Children/adolescents had significantly better HL-specific survival than adults (5-year survival rate, 96% ± 0.4% vs.88% ± 0.3%, p < 0.001). Using a Cox proportional-hazards regression model in patients with classical HL, the prognostic factors significantly impacting survival were age, histology, stage, B symptoms, year of diagnosis, and race. The only adverse prognostic factors that were significant when this analysis was restricted to children/adolescents were stage IV disease and the presence of B symptoms. In conclusion, several differences in clinicopathologic features and outcomes were identified between children/adolescents and adults with HL, and this was particularly noted in young children (<10 years).

    Despite decades of international experience with the use of information and communication technologies in healthcare delivery, widespread telehealth adoption remains limited and progress slow. Escalating health system challenges related to access, cost and quality currently coincide with rapid advancement of affordable and reliable internet based communication technologies creating unprecedented opportunities and incentives for telehealth. In this paper, we will describe how Human Factors Engineering (HFE) and user-centric elements have been incorporated into the establishment of telehealth within a large academic medical center to increase acceptance and sustainability. Through examples and lessons learned we wish to increase awareness of HFE and its importance in the successful implementation, innovation and growth of telehealth programs.

    First created in 1996, the French evaluation, retraining, social and vocational orientation units (UEROS) now play a fundamental role in the social and vocational rehabilitation of patients with brain injury. As of today, there exist 30 UEROS centers in France. While their care and treatment objectives are shared, their means of assessment and retraining differ according to the experience of each one. The objective of this article is to describe the specific programs and the different tools put to work in the UEROS of Limoges. The UEROS of Limoges would appear to offer a form of holistic rehabilitation management characterized by the importance of psycho-education and its type of approach towards vocational reintegration.

    Although more than half a century is passed since space technology was first developed, developing countries are just beginning to enter the arena, focusing mainly on educating professionals. Space technology by itself is an interdisciplinary science, is costly, and developing at a fast pace. Moreover, a fruitful education system needs to remain dynamic if the quality of education is the main concern, making it a complicated system. This paper makes use of the System Engineering Approach and the experiences of developed countries in this area while incorporating the needs of the developing countries to devise a comprehensive program in space engineering at the Master's level. The needs of the developing countries as regards space technology education may broadly be put into two categories: to raise their knowledge of space technology which requires hard work and teamwork skills, and to transfer and domesticate space technology while minimizing the costs and maximizing its effectiveness. The requirements of such space education system, which include research facilities, courses, and student projects are then defined using a model drawn from the space education systems in universities in North America and Europe that has been modified to include the above-mentioned needs. Three design concepts have been considered and synthesized through functional analysis. The first one is Modular and Detail Study which helps students specialize in a particular area in space technology. Second is referred to as Integrated and Interdisciplinary Study which focuses on understanding and development of space systems. Finally, the third concept which has been chosen for the purpose of this study, is a combination of the other two, categorizing the required curriculum into seven modules, setting aside space applications. This helps students to not only specialize in one of these modules but also to get hands-on experience in a real space project through participation in summer group

  14. WHO - IPHECA: Epidemiological aspects

    International Nuclear Information System (INIS)

    In May 1991 the World Health Assembly endorsed the establishment of the International Programme on the Health Effects of the Chernobyl Accident (IPHECA) under the auspices of WHO. Five pilot projects have been carried out within IPHECA in the study territories of Belarus, Russian Federation and Ukraine in a period from 1991 to 1994. This pilot projects dealt with the detection and treatment of leukaemia and related diseases (Haematology Project), thyroid disorders (Thyroid project), brain damage during exposure 'in-utero' (Brain Damage 'in-Utero' project) and with the development of the Chernobyl registries (Epidemiological Registry Project). A fifth pilot project on oral health was performed only in Belarus. Epidemiological investigations have been an important component of all IPHECA pilot projects. Within 'Epidemiological Registry' Project such investigations have been the principal activity. But with respect to other IPHECA projects it was carried out in addition to main objectives relating to medical monitoring, early diagnosis and treatment of specific diseases included in project protocols. To support the epidemiological investigations within IPHECA, WHO supplied 41 computers in Belarus, Russian Federation and Ukraine and provided training for specialists from these countries in internationally recognized centres. The training programmes and host countries were as follows: standardization of epidemiological investigations (United Kingdom), radiation epidemiology (Russia), development of software (United Kingdom), principles of epidemiological investigations (The Czech Republic), cohort investigations (Japan)

    Evolutionary biology, which aims to explain the dynamic process of shaping the diversity of life, has not yet significantly affected thinking in social epidemiology. Current challenges in social epidemiology include understanding how social exposures can affect our biology, explaining the dynamics of society and health, and designing better interventions that are mindful of the impact of exposures during critical periods. I review how evolutionary concepts and tools, such as fitness gradient in cultural evolution, evolutionary game theory, and contemporary evolution in cancer, can provide helpful insights regarding social epidemiology.

    This report is the original research work presented for the attainment of the author master degree and its main objective has been the resolution -by means of friendly programming- of some of the observed problems in the environmental radioactivity laboratory belonging to the Department of Radiological Surveillance and Environmental Radioactivity from CIEMAT. The software has been developed in Visual Basic for applications in Excel files and it solves by macro orders three of the detected problems: a) calculation of characteristic limits for the measurements of the beta total and beta rest activity concentrations according to standards MARLAP, ISO and UNE and the comparison of the three results b) Pb-210 and Po-210 decontamination factor determination in the ultra-low level Am-241 analysis in air samples by alpha spectrometry and c) comparison of two analytical techniques for measuring Pb-210 in air ( direct-by gamma spectrometry- and indirect -by radiochemical separation and alpha spectrometry). The organization processes of the different excel files implied in the subroutines, calculations and required formulae are explained graphically for its comprehension. The advantage of using this kind of programmes is based on their versatility and the ease for obtaining data that lately are required by tables that can be modified as time goes by and the laboratory gets more data with the special applications for describing a method (Pb-210 decontamination factors for americium analysis in air) or comparing temporal series of Pb-210 data analysed by different methods (Pb-210 in air).

  18. Preliminary results of a program of quality assurance applied to the image service of a public hospital

    International Nuclear Information System (INIS)

    Overall quality in radiological protection and medical image depend largely on keeping certain safety standards and technical procedures in good levels. In this way, in June 1998, the Ministry of Health published the document 453 - Guidelines of Radiological Protection to Medical and Dental Practices, defining different levels of actions and responsibility for radiological installation where the critical starting point was the necessity of a previous quality assurance program (QAP) into the radiological service. Preliminary results of a QAP realized in the Department of Radiology of a high complexity Hospital in Rio de Janeiro has showed that, although the importance of 453 Regulation be recognized, there is a few motivation for implementing it. Besides, during 1999 it was possible to identify film losses of 14,9 % related only to the repetition of exposures in the patients, reflecting in terms of cost about U$ 100,000 a year. Results suggest that losses of 64% of total film are due to under or over exposures and 15% are due to inadequate positioning of either film or patient, evidencing the need for training the technical and medical staff .

  5. Causation: the elusive grail of epidemiology.

    Science.gov (United States)

    Karhausen, L R

    2000-01-01

    The paper discusses the evolving concept of causation in epidemiology and its potential interaction with logic and scientific philosophy. Causes are contingent but the necessity which binds them to their effects relies on contrary-to-fact conditionals, i.e. conditional statements whose antecedent is false. Chance instead of determinism plays a growing role in science and, although rarely acknowledged yet, in epidemiology: causes are multiple and chancy; a prior event causes a subsequent event if the probability distribution of the subsequent event changes conditionally upon the probability of the prior event. There are no known sufficient causes in epidemiology. We merely observe tendencies toward sufficiency or tendencies toward necessity: cohort studies evaluate the first tendencies, and case-control studies the latter. In applied sciences, such as medicine and epidemiology, causes are intrinsically connected with goals and effective strategies: they are recipe which have a potential harmful or successful use; they are contrastive since they make a difference between circumstances in which they are present and those in which they are absent: causes do not explain event E but event E rather than even F. Causation is intrinsically linked with the notion of "what is pathological". Any definition of causation will inevitably collapse into the use made of epidemiologic methods. The progressive methodological sophistication of the last forty years is in perfect alignment with a gradual implicit overhaul of our concept of causation. PMID:11080970

    The 18th Maternal and Child Health (MCH) Epidemiology and 22nd CityMatCH MCH Urban Leadership Conference took place in December 2012, covering MCH science, program, and policy issues. Assessing the impact of the Conference on attendees' work 6 months post-Conference provides information critical to understanding the impact and the use of new partnerships, knowledge, and skills gained during the Conference. Evaluation assessments, which included collection of quantitative and qualitative data, were administered at two time points: at Conference registration and 6 months post-Conference. The evaluation files were merged using computer IP address, linking responses from each assessment. Percentages of attendees reporting Conference impacts were calculated from quantitative data, and common themes and supporting examples were identified from qualitative data. Online registration was completed by 650 individuals. Of registrants, 30 % responded to the 6 month post-Conference assessment. Between registration and 6 month post-Conference evaluation, the distribution of respondents did not significantly differ by organizational affiliation. In the 6 months following the Conference, 65 % of respondents reported pursuing a networking interaction; 96 % shared knowledge from the Conference with co-workers and others in their agency; and 74 % utilized knowledge from the Conference to translate data into public health action. The Conference produced far-reaching impacts among Conference attendees. The Conference served as a platform for networking, knowledge sharing, and attaining skills that advance the work of attendees, with the potential of impacting organizational and workforce capacity. Increasing capacity could improve MCH programs, policies, and services, ultimately impacting the health of women, infants, and children. PMID:25107597

    Chalmers, A F

    1982-01-01

    This article refutes the claim that the field of epidemiology and community health would benefit from the application of the scientific method. It is argued that the methods of physics are not appropriate for other disciplines. When applied to the social sciences, positivism is a conservatizing force, causing theory to become based on a mere description of social phenomenon. Since it cannot lead to a deep understanding of social phenomena, positivism is incapable of revealing ways in which society could be radically changed. Moreover, such theory is far from neutral. Rather, it is formed and influenced by the forms of life experienced and practiced in the society. This is illustrated by an analysis of the origin of modern physics at the time when society was changing from a feudal to capitalist form of organization. It is concluded that advances will be made in epidemiology and community health when this field breaks from its focus on the individual and incorporates class into its analysis. However, given the interconnection between social structure and social theory, resistance to such a radical change can be expected. PMID:7141777

    Hastings, Richard P

    2003-04-01

    There have been few studies of the impact of intensive home-based early applied behavior analysis (ABA) intervention for children with autism on family functioning. In the present study, behavioral adjustment was explored in 78 siblings of children with autism on ABA programs. First, mothers' ratings of sibling adjustment were compared to a normative sample. There were no reported increases in behavioral adjustment problems in the present sample. Second, regression analyses revealed that social support functioned as a moderator of the impact of autism severity on sibling adjustment rather than a mediator or compensatory variable. In particular, siblings in families with a less severely autistic child had fewer adjustment problems when more formal social support was also available to the family. The implications of these data for future research and for practice are discussed. PMID:12757353

    Scholars have argued that theoretical insights of critical medical anthropology should be applied to the analysis of complementary and alternative medicine in order to develop more critically engaged integrative medicine. In this essay we focus on nature cure in the context of India's contemporary epidemiological transition as an example of why engaged integrative medicine is important for public health, and how the institutionalization of nature cure treatment in India provides a critical framework for the development of programs focused on holistic treatment and prevention. After providing an overview of the epidemiological transition in contemporary India, we develop this argument through an examination of illustrative cases in a clinic that operates within the structure of India's Central Council for Research on Yoga and Naturopathy. Based on a review of recent history and contemporary practice we describe how a system of medicine that makes use exclusively of air, earth, sunlight, water and food has been institutionalized and professionalized in India. Whereas biomedical treatment for chronic non-communicable diseases is focused on the problem of curing individual diseases, nature cure establishes a regimen of personalized public healthcare for the integrated management of symptoms. We argue that nature cure is based on an ecological understanding of health, thus providing treatment that reflects a broad appreciation for the risk factors that characterize India's current crises of public health.

    2012-01-01

    Full Text Available We present a hybridization of two different approaches applied to the well-known Capacitated Facility Location Problem (CFLP. The Artificial Bee algorithm (BA is used to select a promising subset of locations (warehouses which are solely included in the Mixed Integer Programming (MIP model. Next, the algorithm solves the subproblem by considering the entire set of customers. The hybrid implementation allows us to bypass certain inherited weaknesses of each algorithm, which means that we are able to find an optimal solution in an acceptable computational time. In this paper we demonstrate that BA can be significantly improved by use of the MIP algorithm. At the same time, our hybrid implementation allows the MIP algorithm to reach the optimal solution in a considerably shorter time than is needed to solve the model using the entire dataset directly within the model. Our hybrid approach outperforms the results obtained by each technique separately. It is able to find the optimal solution in a shorter time than each technique on its own, and the results are highly competitive with the state-of-the-art in large-scale optimization. Furthermore, according to our results, combining the BA with a mathematical programming approach appears to be an interesting research area in combinatorial optimization.

    Full Text Available Introduction: Unsafe sexual behaviors as important risky behaviors can expose individuals and society to dangerous infectious disease such as AIDS and viral hepatitis. Considering the high prevalence of unsafe sexual behaviors, this study aimed to determine the effect of educational programs to encourage safe sexual behaviors among substance abusers referred to substance abuse treatment centers in Hamadan, Western Iran by applying the theory of planned behavior. Materials & Methods: This quasi-experimental study was performed on 104 men substance abusers (52 participants in each of the control and intervention groups referred to substance abuse treatment centers in Hamadan. Data collection tool was a questionnaire containing demographic information and the theory of planned behavior constructs. Before the educational program, questionnaires were completed by both groups. After the pretest in both groups, participants in the intervention group participated in four educational sessions designed based on the theory of planned behavior. Two months after the end of program, posttest was performed. Data was analyzed using independent T-test, chi-square, fisher exact test, McNemar’s test and multiple linear regressions using SPSS-16. Results: After educational intervention, the mean scores of the theory constructs (attitude toward behavior, subjective norms, behavioral control, behavioral intention and behaviors, in the intervention group increased significantly (P<0.05, despite the fact, changes were not significant in the control group. Conclusion: Implementation of educational courses to encourage safe sexual behaviors based on the theory of planned behavior can be beneficial for substance abusers referred to substance abuse treatment centers.

    2016-01-01

    Although the use of phylogenetic trees in epidemiological investigations has become commonplace, their epidemiological interpretation has not been systematically evaluated. Here, we use an HIV-1 within-host coalescent model to probabilistically evaluate transmission histories of two epidemiologically linked hosts. Previous critique of phylogenetic reconstruction has claimed that direction of transmission is difficult to infer, and that the existence of unsampled intermediary links or common sources can never be excluded. The phylogenetic relationship between the HIV populations of epidemiologically linked hosts can be classified into six types of trees, based on cladistic relationships and whether the reconstruction is consistent with the true transmission history or not. We show that the direction of transmission and whether unsampled intermediary links or common sources existed make very different predictions about expected phylogenetic relationships: (i) Direction of transmission can often be established when paraphyly exists, (ii) intermediary links can be excluded when multiple lineages were transmitted, and (iii) when the sampled individuals’ HIV populations both are monophyletic a common source was likely the origin. Inconsistent results, suggesting the wrong transmission direction, were generally rare. In addition, the expected tree topology also depends on the number of transmitted lineages, the sample size, the time of the sample relative to transmission, and how fast the diversity increases after infection. Typically, 20 or more sequences per subject give robust results. We confirm our theoretical evaluations with analyses of real transmission histories and discuss how our findings should aid in interpreting phylogenetic results. PMID:26903617

    Objective The purpose of this project was to develop an English-Russian Epidemiology Dictionary, which is needed for improved international collaboration in public health surveillance. Introduction As part of the US Department of Defense strategy to counter biological threats, the Defense Threat Reduction Agency’s Cooperative Biological Engagement Program is enhancing the capabilities of countries in the former Soviet Union (FSU) to detect, diagnose, and report endemic and epidemic, man-made or natural cases of especially dangerous pathogens. During these engagements, it was noted that Western-trained and Soviet-trained epidemiologists have difficulty, beyond that of simple translation, in exchanging ideas. The Soviet public health system and epidemiology developed independently of that of other nations. Whereas epidemiology in the West is thought of in terms of disease determinants in populations and relies on statistics to make inferences, classical Soviet epidemiology is founded on a more ecological view with the main focus on infectious diseases’ spread theory. Consequently many fundamental Soviet terms and concepts lack simple correlates in English and other languages outside the Soviet sphere; the same is true when attempting to translate from English to Russian and other languages of the FSU. Systematic review of the differences in FSU and Western epidemiologic concepts and terminology is therefore needed for strengthening understanding and collaboration in disease surveillance, pandemic preparedness, response to biological terrorism, etc. Methods Following an extensive search of the Russian and English literature by a working group of Western and FSU epidemiologists, we created a matrix containing English and Russian definitions of key epidemiologic terms found in FSU and Western epidemiology manuals and dictionaries, such as A Dictionary of Epidemiology (1), Epidemiology Manual (2) and many other sources. Particular emphasis was placed on terms

  2. Epidemiology of malaria in Malaysia.

    Malaria is a major public health problem in Malaysia, particularly in peninsular Malaysia and the state of Sabah. An eradication program started in the states of Sabah and Sarawak in 1961 initially was remarkably successful. A similar but staged program was started in peninsular Malaysia in 1967 and was also quite successful. However, a marked upsurge in incidence in Sabah in 1975-1978 showed that malaria is still a major hazard. The disease leads to great economic losses in terms of the productivity of the labor force and the learning capacity of schoolchildren. The topography, the climate, and the migrations of the people due to increased economic activity are similar in peninsular Malaysia, Sabah, and Sarawak. However, the epidemiologic picture differs strikingly from area to area in terms of species of vectors, distribution of parasitic species, and resistance of Plasmodium falciparum to chloroquine. Likewise, the problems faced by the eradication or control programs in the three regions are dissimilar. Because solutions to only some of these problems are possible, the eradication of malaria in Malaysia is not likely in the near future. However, the situation offers an excellent opportunity for further studies of antimalaria measures. PMID:6755616

    The purpose of this chapter is to describe the basic principles and advancements in the molecular epidemiology of foodborne pathogens. Epidemiology is the study of the distribution and determinants of infectious diseases and/or the dynamics of disease transmission. The goals of epidemiology include the identification of physical sources, routes of transmission of infectious agents, and distribution and relationships of different subgroups. Molecular epidemiology is the study of epidemiology at the molecular level. It has been defined as "a science that focuses on the contribution of potential genetic and environmental risk factors, identified at the molecular level, to the etiology, distribution and prevention of diseases within families and across populations".

The present paper is part of a broader study on the selection of sanitary indicators to be used as "sentinel indicators" for prevention and control of diseases associated to water and sanitation. In this context, this paper presents a brief literature review, descriptive statistics of some epidemiological indicators collected from municipalities of 4 Brazilian States, as well as a discussion on the applicability of these indicators in studies of this nature. Among the epidemiological indicators evaluated, infant mortality, diarrhoea mortality in children under 5 years old and the diarrhoea morbidity in children under 5 years old based on data from the Brazilian Monitoring of Acute Diarrhoeal Disease program seem to be the more adequate.

In this context, a study evaluated strategies to curb livestock-associated methicillin resistant Staphylococcus aureus (LA-MRSA. Fifty-one veal calf farms were assigned to one of 3 study arms: RAB farms reducing antimicrobials by protocol; RAB-CD farms reducing antimicrobials by protocol and applying a cleaning and disinfection program; and Control farms without interventions. MRSA carriage was tested in week 0 and week 12 of 2 consecutive production cycles in farmers, family members and veal calves. Interventions were validated and a cyclic rise in MRSA-prevalence in animals was shown with a more moderate increase in RAB farms. Prevalence in humans declined parallel over time in the study arms but RAB farms were at the lowest MRSA levels from the beginning of the study. In RAB-CD farms, human and animal prevalence did not differ from Control farms and MRSA air loads were significantly higher than in the other study arms. Mimicking the national trend, an overall AMU decrease (daily dosages per animal per cycle (DDDA/C was observed over 4 pre-study and the 2 study cycles; this trend did not have a significant effect on a set of evaluated farm technical parameters. AMU was positively associated with MRSA across study arms (ORs per 10 DDDA/C increase = 1.26 for both humans (p = 0.07 and animals (p = 0.12 in first cycle. These results suggest that AMU reduction might be a good strategy for curbing MRSA in veal calf farming, however the specific cleaning and disinfecting program in RAB-CD farms was not effective. The drop in MRSA prevalence in people during the study could be attributed to the observed long-term AMU decreasing trend.

    2008-03-01

    This study provides a description of the design and development of guidelines and programs for a national core curriculum for special education in Israel. Israel was exposed during the 1970s to the ideology of normalization. Later on, toward the end of the 1980s, the concept of quality of life was added. Several research studies were conducted, resulting in the following core ideas about education: a shift of emphasis from teaching independent-living skills to teaching autonomy, self-awareness, self-direction, and interdependence is required. On the basis of these ideas, a new model of instruction was devised and termed the 'cycle of internalized learning' (CIL). The CIL is based on a holistic orientation toward the student and builds on abilities rather than disabilities. The peer group is the basic unit of instruction. Attention is on processes and outcomes. The CIL involves several clearly defined teaching steps: (i) opening--the presentation of the subject matter; (ii) discussion--a conceptual analysis of the subject; (iii) open conversation--students discuss the issues they raised during the first session, express their personal life experiences while applying the new concepts they learned, and suggest possible solutions to problems; (iv) trying out the solutions suggested by students; and (v) repeated discussions, to arrive at personal and social conclusions. Currently there are three published units of the CIL: (i) Social Education, (ii) Career Education, and (iii) Towards Leaving Home for Independent Living in the Community. The fourth unit, on citizenship education through the use of computers, is in its final stages of preparation. The success of the implementation of the program is expressed both at the students' level--as an enhanced sense of self-worth and self-confidence, as well as enhanced academic achievements and social skills--and at the teachers' level--as a paradigm shift from a medical model of approach to students with disabilities to a

    The utility of spatial data products and tools to assess risk and effectively manage wildfires has increased, highlighting the need for communicating information about these new capabilities to decision makers, resource managers, and community leaders. NASA's Applied Remote Sensing Training (ARSET) program works directly with agencies and policy makers to develop in-person and online training courses that teach end users how to access, visualize, and apply NASA Earth Science data in their profession. The expansion of ARSET into wildfire applications began in 2015 with a webinar and subsequent in-person training hosted in collaboration with Idaho State University's (ISU) GIS Training and Research Center (TReC). These trainings featured presentations from the USDA Forest Service's Remote Sensing Training and Applications Center, the Land Processes DAAC, Northwest Nazarene University, NASA Goddard Space Flight Center, and ISU's GIS TReC. The webinar focused on providing land managers, non-governmental organizations, and international management agencies with an overview of 1) remote sensing platforms for wildfire applications, 2) products for pre- and post-fire planning and assessment, 3) the use of terrain data, 4) new techniques and technologies such as Unmanned Aircraft Systems and the Soil Moisture Active Passive Mission (SMAP), and 5) the RECOVER Decision Support System. This training highlighted online tools that engage the wildfire community through collaborative monitoring and assessment efforts. Webinar attendance included 278 participants from 178 organizations in 42 countries and 33 US states. The majority of respondents (93%) from a post-webinar survey indicated they displayed improvement in their understanding of specific remote-sensing data products appropriate for their work needs. With collaborative efforts between federal, state, and local agencies and academic institutions, increased use of NASA Earth Observations may lead to improved near real

    Colorectal cancer is currently the third deadliest cancer in the United States and will claim an estimated 49,190 U.S. lives in 2016. The purpose of this review is to summarize our current understanding of this disease, based on nationally published statistics and information presented in peer-reviewed journal articles. Specifically, this review will cover the following topics: descriptive epidemiology (including time and disease trends both in the United States and abroad), risk factors (environmental, genetic, and gene-environment interactions), screening, prevention and control, and treatment. Landmark discoveries in colorectal cancer risk factor research will also be presented. Based on the information reviewed for this report, we suggest that future U.S. public health efforts aim to increase colorectal cancer screening among African American communities, and that future worldwide colorectal cancer epidemiology studies should focus on researching nutrient-gene interactions towards the goal of improving personalized treatment and prevention strategies.

    Full Text Available A new concept of within-individual epidemiology termed myEpi is introduced. It is argued that traditional epidemiological methods, which are usually applied to populations of humans, can be applicable to a single individual and thus used for self-monitoring and forecasting of epidemic outbreaks within an individual. Traditional epidemiology requires that results be generalizable to a predefined population. The key component of myEpi is that a single individual may be viewed as an entire population of events and thus the analysis should be generalizable to this population. Applications of myEpi are aimed for, but not limited to, the analysis of data collected by individuals with the help of wearable sensors and digital diaries. These data can include physiological measures and records of healthy and risky behaviors (e.g., exercise, sleep, smoking, food consumption, alcohol and drug use. Although many examples of within-individual epidemiology exist, there is a pressing need for systematic guidance to the analysis and interpretation of intensive individual-level data. myEpi serves this need by adapting statistical methods (e.g. regressions, hierarchical models, survival analysis, agent-based models to individual-level data.

    The development of Occupational Epidemiology in Italy is closely correlated with the political and social awareness of the needs of preventive strategies in the workplace. In the late '60s the Trade Unions supported a model of intervention based on the involvement of the so-called "Homogeneous group of workers" in the validation of the preventive measures taken on the workplace. In spite of the shortcomings of the model, it was extremely effective resulting in enhanced perception of the priority of preventive strategies and in the formation within the National Health Service of the Occupational Health Services. In Italy over the period 1973-2002 there has been an impressive trend of research in field of occupational epidemiology (a search on Medline shows an increasing trend over the years and, in terms of international comparison, higher figures than in Germany, France and Spain). Occupational Epidemiology is now present in the activities of the local Occupational Health Services and in the teaching activities of the Medical Schools throughout the country. PMID:14582235

    Objective To analyze the epidemiologic and surveillance data of hemorrhagic fever with renal syndrome (HERS) in China, from 2005 to 2008, to describe the epidemiology and trend of HERS. Methods Descriptive epidemiology were studied to analyze the surveillance data from 2005 to 2008, collected from both the internet-based national notifiable disease reporting system and 40 HFRS sentinel sites developed since 2005 in 40 counties around China. Results A total of 56 077 HERS cases and 692 deaths reported in China with case fatality rate as 1.23%. Morbidity and mortality had been annually decreasing since 2004. The top 7 provinces with HFRS cases were Heilongjiang, Lianning, Jilin, Shandong, Shaanxi, Hebei and Zhejiang, which had a total of 44 081 cases reported, accounting for 78.61% of the total number of cases, in the nation. More cases were reported in spring and autumn-winter season, with the peak in November. Cases reported in males were 3.13 times of the females and most cases seen in young and middle-aged farmers. The density and the virus carrying rate of animal hosts and the distribution of dominant species were relatively stable and similar to the previous findings. Apodemus agrarius and Rattus norvegicus were still the most common and predominant animal hosts. No genetic mutation of Hantavirus was detected in the surveillance program. Conclusion The continuous descending trend of the HERS epidemics could be related to the successful strategies on comprehensive prevention and control measures, as controlling the number of rodents and vectors, carrying out HERS vaccination campaign and health education by the local health care takers in the recent years. Implementation of the new national Expanded Program of Immunization on HFRS vaccine in high-risk areas may further reduce the epidemics. However,both the density and the virus carried rate among the host animals remain high in some areas, together with the emergence of new epidemic areas, all call for more

    The global statistics of diabetes mellitus in year 2013 indicated, about 382 million people had this disease worldwide, with type 2 diabetes making up about 90 % of the cases. This is equal to 8.3 % of the adult population with equal rates in both women and men. In year 2012 and 2013 diabetes resulted in mortality of 1.5-5.1 million people per year, making it the 8th leading cause of death in the world. It is predicted that by year 2035 about 592 million people will die of diabetes. The economic cost of diabetes seems to have increased worldwide. An average age of onset of diabetes is 42.5 years and could be due to consumption of high sugar and high-calorie diet, low physical activity, genetic susceptibility, and lifestyle. Approximately 8 % children and about 26 % young adults have diabetes mellitus in the world. The results of epidemiological study of type 1 diabetes mellitus (T1D) are presented by demographic, geographic, biologic, cultural, and other factors in human populations. The prevalence of T1D has been increased by 2-5 % worldwide and its prevalence is approximately one in 300 in US by 18 years of age. The epidemiological studies are important to study the role, causes, clinical care, prevention, and treatment of type1 diabetes in pregnant women and their children before and after birth. In this article, causes, diagnosis, symptoms, treatment and medications, and epidemiology of diabetes will be described. PMID:25711186

    Reliable predictors of poor clinical outcome despite successful revascularization might help select patients with acute ischemic stroke for thrombectomy. We sought to determine whether baseline Alberta Stroke Program Early CT Score (ASPECTS) applied to CT angiography source images (CTA-SI) is useful in predicting futile recanalization. Data are from the FUN-TPA study registry (ClinicalTrials.gov; NCT02164357) including patients with acute ischemic stroke due to proximal arterial occlusion in anterior circulation, undergoing reperfusion therapies. Baseline non-contrast CT and CTA-SI-ASPECTS, time-lapse to image acquisition, occurrence, and timing of recanalization were recorded. Outcome measures were NIHSS at 24 h, symptomatic intracranial hemorrhage, modified Rankin scale score, and mortality at 90 days. Futile recanalization was defined when successful recanalization was associated with poor functional outcome (death or disability). Included were 110 patients, baseline NIHSS 17 (IQR 12; 20), treated with intravenous thrombolysis (IVT; 45 %), primary mechanical thrombectomy (MT; 16 %), or combined IVT + MT (39 %). Recanalization rate was 71 %, median delay of 287 min (225; 357). Recanalization was futile in 28 % of cases. In an adjusted model, baseline CTA-SI-ASPECTS was inversely related to the odds of futile recanalization (OR 0.5; 95 % CI 0.3-0.7), whereas NCCT-ASPECTS was not (OR 0.8; 95 % CI 0.5-1.2). A score ≤5 in CTA-SI-ASPECTS was the best cut-off to predict futile recanalization (sensitivity 35 %; specificity 97 %; positive predictive value 86 %; negative predictive value 77 %). CTA-SI-ASPECTS strongly predicts futile recanalization and could be a valuable tool for treatment decisions regarding the indication of revascularization therapies. (orig.)

    Conventional instruction in science often proceeds from the general to the specific and from text to action. Fundamental terminologies, concepts, and ideas that are often abstract are taught first and only after such introductory processes can a student engage in research. Many students struggle to find relevance when presented information without context specific to their own experiences. This challenge is exacerbated for students whose social circles do not include adults who can validate scientific learning from their own experiences. Lamont-Doherty's Secondary School Field Research Program inverts the standard paradigm and places small groups of students in research projects where they begin by performing manageable tasks on complex applied research projects. These tasks are supplemented with informal mentoring and relevant articles (~1 per week). Quantitative metrics suggest the approach is highly successful—most participants report a dramatic increase in their enthusiasm for science, 100% attend college, and approximately 50% declare majors in science or technology. We use one project, the construction of a microbial battery, to illustrate this novel model of science learning and argue that it should be considered a best practice for project-based science education. The goal of this project was to build a rechargeable battery for a mobile phone based on a geochemical cycle, to generate and store electricity. The students, mostly from ethnic groups under-represented in the STEM fields, combined concepts and laboratory methods from biology, chemistry and physics to isolate photosynthetic bacteria from a natural salt marsh, and made an in situ device capable of powering a light bulb. The younger participants had been exposed to neither high school chemistry nor physics at the start of the project, yet they were able to use the project as a platform to deepen their science knowledge and their desire for increased participation in formal science education.

    Full Text Available Definitions of epidemiological concepts regarding disease monitoring and surveillance can be found in textbooks on veterinary epidemiology. This paper gives a review of how the concepts: monitoring, surveillance, and disease control strategies are defined. Monitoring and surveillance systems (MO&SS involve measurements of disease occurrence, and the design of the monitoring determines which types of disease occurrence measures can be applied. However, the knowledge of the performance of diagnostic tests (sensitivity and specificity is essential to estimate the true occurrence of the disease. The terms, disease control programme (DCP or disease eradication programme (DEP, are defined, and the steps of DCP/DEP are described to illustrate that they are a process rather than a static MO&SS.

    Coalescent theory is routinely used to estimate past population dynamics and demographic parameters from genealogies. While early work in coalescent theory only considered simple demographic models, advances in theory have allowed for increasingly complex demographic scenarios to be considered. The success of this approach has lead to coalescent-based inference methods being applied to populations with rapidly changing population dynamics, including pathogens like RNA viruses. However, fitting epidemiological models to genealogies via coalescent models remains a challenging task, because pathogen populations often exhibit complex, nonlinear dynamics and are structured by multiple factors. Moreover, it often becomes necessary to consider stochastic variation in population dynamics when fitting such complex models to real data. Using recently developed structured coalescent models that accommodate complex population dynamics and population structure, we develop a statistical framework for fitting stochastic epidemiological models to genealogies. By combining particle filtering methods with Bayesian Markov chain Monte Carlo methods, we are able to fit a wide class of stochastic, nonlinear epidemiological models with different forms of population structure to genealogies. We demonstrate our framework using two structured epidemiological models: a model with disease progression between multiple stages of infection and a two-population model reflecting spatial structure. We apply the multi-stage model to HIV genealogies and show that the proposed method can be used to estimate the stage-specific transmission rates and prevalence of HIV. Finally, using the two-population model we explore how much information about population structure is contained in genealogies and what sample sizes are necessary to reliably infer parameters like migration rates.

  9. The Epidemiology of Sarcopenia.

    2015-01-01

    The aim of this review is to describe the epidemiology of sarcopenia, specifically prevalence, health outcomes, and factors across the life course that have been linked to its development. Sarcopenia definitions involve a range of measures (muscle mass, strength, and physical performance), which tend to decline with age, and hence sarcopenia becomes increasingly prevalent with age. Less is known about prevalence in older people in hospital and care homes, although it is likely to be higher than in community settings. The range of measures used, and the cutpoints suggested for each, presents a challenge for comparing prevalence estimates between studies. The importance of sarcopenia is highlighted by the range of adverse health outcomes that strength and physical performance (and to a lesser extent, muscle mass) have been linked to. This is shown most strikingly by the finding of increased all-cause mortality rates among those with weaker grip strength and slower gait speed. A life course approach broadens the window for our understanding of the etiology of sarcopenia and hence the potential intervention. An example is physical activity, with increased levels across midadulthood appearing to increase muscle mass and strength in early old age. Epidemiologic studies will continue to make an important contribution to our understanding of sarcopenia and possible avenues for intervention and prevention.

    Sporotrichosis is an endemic mycosis caused by the dimorphic fungus Sporothrix schenckii sensu lato. It has gained importance in recent years due to its worldwide prevalence, recognition of multiple cryptic species within the originally described species, and its distinctive ecology, distribution, and epidemiology across the globe. In this review, we describe the current knowledge of the taxonomy, ecology, prevalence, molecular epidemiology, and outbreaks due to S. schenckii sensu lato. Despite its omnipresence in the environment, this fungus has remarkably diverse modes of infection and distribution patterns across the world. We have delved into the nuances of how sporotrichosis is intimately linked to different forms of human activities, habitats, lifestyles, and environmental and zoonotic interactions. The purpose of this review is to stimulate discussion about the peculiarities of this unique fungal pathogen and increase the awareness of clinicians and microbiologists, especially in regions of high endemicity, to its emergence and evolving presentations and to kindle further research into understanding the unorthodox mechanisms by which this fungus afflicts different human populations.

    2015-01-01

    Formerly named carcinoids, neuroendocrine tumors originate from diffuse endocrine cells, can involve any part of the gastrointestinal tract, endocrine pancreas and bronchopulmonary (BP) tree, and have a wide range of malignant potential. This chapter summarizes the data available on the epidemiology of neuroendocrine neoplasia (NEN) from around the world, including the relative frequency according to organ of origin, annual incidence rates (IR) and trends in IR at the various anatomic sites, age and stage at presentation, racial and gender differences in IR and 5-year survival rates. Over time, changes have been made in the classification and registration of NEN, both in the same registry and across the globe, thus confounding the possibility to draw conclusions as to the true rise in IR of NEN that is observed all over the world. BP NEN has become the most common site in many western countries, while NEN of the rectum is more common in the Far East. In some countries, appendiceal NEN is the most common site in females. When compared to adenocarcinoma of the same location, the prognosis of NEN patients is better. Five-year survival rates are highest for NEN originating in the rectum and appendix, but lower in small intestinal and pancreatic NEN. Future research is needed to understand the contribution of genetic and environmental factors to NEN epidemiology. PMID:26303701

    Full Text Available Stroke is a huge public health problem because of its high morbidity and disability. The epidemiology of stroke is of relevance to construct practical paradigms to tackle this major health issue in the community. Recent data have shown that about 72-86% of strokes are ischemic, 9-18% are due to hemorrhage (intracerebral of subarachnoid and the rest are undefined. The risk factors for stroke are multiple and combined. At present, stroke is no more considered as unavoidable and untreatable. It is an emergency and specialized units and teams improve outcome and lower costs. Death related to stroke is declining in many countries and in both sexes. This decrease in multifactorial. The detection and more effective treatment of hypertension may play an important factor, as well as the improved medical care and improvement in diagnostic procedures. While stroke incidence appears stable and stroke mortality is slowly declining, the absolute magnitude of stroke is likely to grow over the next 30 years. as the population ages, the absolute number of stroke victims and demands on healthcare and other support systems is likely to increase substantially in the future. Keeping this in perspective, this chapter shall focus on the epidemiology of stroke in the world and in Indian, in particular.

    Science.gov (United States)

    Kodama, H; Ohno, Y

    1989-06-01

    In this paper, urolithiasis is remarked from the standpoint of descriptive epidemiology, which examines the frequency distribution of a given disease in a population in terms of time, place and personal characteristics with an aim of identifying risk factors or some clues to the etiology. Some descriptive epidemiological features of urolithiasis are summarized. Prevalence rate is around 4% (4-15% in males and 4-8% in females), and incidence rate varies from area to area: 53.2 per 100,000 population in 1975 in Japan, 364 in 1976 in Malaysia, and 540 in 1979 in West Germany. Prevalence and/or incidence rates have, in general, increased in the developed countries since World War II and in the developing countries as well, where upward trends are quite analogous to the trends observed in the nineteenth century in Europe. Recurrence rate, which is much higher in males than in females, ranges from 31% to 75%, depending on the follow-up periods. In the industrialized countries, upper urinary (renal and ureteral) stones account for more than 90% of total stones, which are ordinarily calcium complexes in composition. More common in the developing countries are lower urinary (bladder and urethral) stones, frequently composed of magnesium ammonium phosphate, which indicates a close association with urinary tract infections. Variations in frequency are evident by season and by region within a country. Age and sex differentials in urinary stone formers are substantial: more common in males 30-40 years old in the industrialized countries and in children under 10 years old in the developing countries. Racial differentials are also noted; blacks appear to suffer less frequently than whites. Stone formers experience more frequent episodes of stone formation in their family members, particularly father and brothers, than non-stone formers. These findings on racial differentials and family preponderance suggest the possible relevance of genetic factors in stone formation. Stone

  19. The Epidemiology of Sarcoma

    Full Text Available Abstract Sarcomas account for over 20% of all pediatric solid malignant cancers and less than 1% of all adult solid malignant cancers. The vast majority of diagnosed sarcomas will be soft tissue sarcomas, while malignant bone tumors make up just over 10% of sarcomas. The risks for sarcoma are not well-understood. We evaluated the existing literature on the epidemiology and etiology of sarcoma. Risks for sarcoma development can be divided into environmental exposures, genetic susceptibility, and an interaction between the two. HIV-positive individuals are at an increased risk for Kaposi’s sarcoma, even though HHV8 is the causative virus. Radiation exposure from radiotherapy has been strongly associated with secondary sarcoma development in certain cancer patients. In fact, the risk of malignant bone tumors increases as the cumulative dose of radiation to the bone increases (p for trend

    1989-01-01

    The literature published between 1965 and 1989 on the cancer epidemiology of woodworking in furniture industries and carpentry shops in 17 countries is reviewed. Included are some unpublished data obtained through personal communication with epidemiologists or collected from doctoral dissertations. Of 5,785 cases with sino-nasal cancers, about 23% were found to be woodworkers. Dusty jobs, especially wood processing using high-speed machines, are mainly associated with the enhanced incidence of nasal adenocarcinomas. The latency periods of the latter tumors ranged from 7 to 69 years in five European countries. A variety of neoplasias of the respiratory, digestive, and urinary tracts as well as the hemopoietic and lymphatic systems, including Hodgkin's disease are reported to be significantly associated with occupational exposure to wood dust. These data suggest that the exposure to some types of wood dust might cause a systemic rather than local neoplastic disorder.

  5. Retrospective internal radiation exposure assessment in occupational epidemiology

    International Nuclear Information System (INIS)

    Epidemiologic studies of workers at U.S. Department of Energy facilities are being conducted by the U.S. National Institute for Occupational Safety and Health to evaluate the health risk associated with exposure to sources of external and internal ionizing radiation. While exposure to external sources of radiation can be estimated from personal dosimeter data, reconstruction of exposure due to internally deposited radioactivity is more challenging because bioassay monitoring data is frequently less complete. Although comprehensive monitoring was provided for workers with the highest internal exposures, the majority of workers were monitored relatively infrequently. This monitoring was conducted to demonstrate compliance with regulations rather than to evaluate exposure for use in epidemiologic studies. Attributes of past internal monitoring programs that challenge accurate exposure assessment include: incomplete characterization of the workplace source term; a lack of timely measurements; insensitive and/or nonspecific bioassay measurements; and the presence of censored data. In spite of these limitations, many facilities have collected a large amount of worker and workplace monitoring information that can be used to evaluate internal exposure while minimizing worker misclassification. This paper describes a systematic approach for using the available worker and workplace monitoring data that can lead to either a qualitative or quantitative retrospective assessment of internal exposures. Various aspects of data analysis will be presented, including the evaluation of minimum detectable dose, the treatment of censored data, and the use of combinations of bioassay and workplace data to characterize exposures. Examples of these techniques applied to a cohort study involving chronic exposure scenarios to uranium are provided. A strategy for expressing exposure or dose in fundamental, unweighted units related to the quantity of radiation delivered to an organ will also

    Despite acne being an almost universal condition in younger people, relatively little is known about its epidemiology. We sought to review what is known about the distribution and causes of acne by conducting a systematic review of relevant epidemiological studies. We searched Medline and Embase to the end of November 2011. The role of Propionibacterium acnes in pathogenesis is unclear: antibiotics have a direct antimicrobial as well as an anti-inflammatory effect. Moderate-to-severe acne affects around 20% of young people and severity correlates with pubertal maturity. Acne may be presenting at a younger age because of earlier puberty. It is unclear if ethnicity is truly associated with acne. Black individuals are more prone to postinflammatory hyperpigmentation and specific subtypes such as 'pomade acne'. Acne persists into the 20s and 30s in around 64% and 43% of individuals, respectively. The heritability of acne is almost 80% in first-degree relatives. Acne occurs earlier and is more severe in those with a positive family history. Suicidal ideation is more common in those with severe compared with mild acne. In the U.S.A., the cost of acne is over 3 billion dollars per year in terms of treatment and loss of productivity. A systematic review in 2005 found no clear evidence of dietary components increasing acne risk. One small randomized controlled trial showed that low glycaemic index (GI) diets can lower acne severity. A possible association between dairy food intake and acne requires closer scrutiny. Natural sunlight or poor hygiene are not associated. The association between smoking and acne is probably due to confounding. Validated core outcomes in future studies will help in combining future evidence. PMID:23210645

    2008-01-01

    It is estimated that approximately 130-170 million people worldwide are infected with hepatitis C virus (HCV). According to data from WHO community and blood donor surveys, the African and Eastern Mediterranean countries report the highest prevalence rates (>10%). The rates of infection in the general population and the incidence of newly-acquired cases indicate an appreciable change in the epidemiology of the infection in recent years. Prior to the widespread screening of blood donations, infected blood and blood products represented a common source of infection. On the other hand, the high peak in HCV antibodies among the elderly in Italian epidemiological studies on the population at large reflects a cohort effect due to an epidemic of HCV infection occurring after the Second World War. According to data reported by the CDC Surveillance System, the incidence of acute hepatitis C has declined since the late 1980s. In 2005, as in previous years, the majority of such cases in North America and Northern Europe occurred among young adults and injected drug use was the most common risk factor. Other, less commonly reported modes of HCV acquisition are occupational exposure to blood, high-risk sexual activity, tattooing, body piercing and other forms of skin penetration. Finally, the overall rate of mother-to-child transmission from HCV-infected, HIV-negative mothers has been estimated at around 5% (coinfection with HIV raises this figure to 19.4%). HCV prevention relies on identifying and counseling uninfected persons at risk of contracting hepatitis C. PMID:18673187

    Full Text Available Paul D ReadyDisease Control Department, Faculty of Infectious and Tropical Diseases, London School of Hygiene and Tropical Medicine, London, UKAbstract: Leishmania species are the causative agents of leishmaniasis, a neglected tropical disease. These parasitic protozoans are usually transmitted between vertebrate hosts by the bite of blood sucking female phlebotomine sand flies. This review focuses on the two parasites causing most human visceral leishmaniasis (VL, which leads to substantial health problems or death for up to 400,000 people per year. Except for travel cases, Leishmania donovani infections are restricted to the (sub-tropics of Asia and Africa, where transmission is mostly anthroponotic, while Leishmania infantum occurs in the drier parts of Latin America as well as in the Mediterranean climate regions of the Old World, with the domestic dog serving as the main reservoir host. The prevalence of VL caused by L. infantum has been declining where living standards have improved. In contrast, infections of L. donovani continue to cause VL epidemics in rural areas on the Indian subcontinent and in East Africa. The current review compares and contrasts these continental differences and suggests priorities for basic and applied research that might improve VL control. Transmission cycles, pathogenesis, diagnosis, treatment and prognosis, prevention (including vector control, surveillance, transmission modeling, and international control efforts are all reviewed. Most case detection is passive, and so routine surveillance does not usually permit accurate assessments of any changes in the incidence of VL. Also, it is not usually possible to estimate the human inoculation rate of parasites by the sand fly vectors because of the limitations of survey methods. Consequently, transmission modeling rarely passes beyond the proof of principle stage, and yet it is required to help develop risk factor analysis for control programs. Anthroponotic VL

    2014-01-01

    Applied Dynamics is an important branch of engineering mechanics widely applied to mechanical and automotive engineering, aerospace and biomechanics as well as control engineering and mechatronics. The computational methods presented are based on common fundamentals. For this purpose analytical mechanics turns out to be very useful where D’Alembert’s principle in the Lagrangian formulation proves to be most efficient. The method of multibody systems, finite element systems and continuous systems are treated consistently. Thus, students get a much better understanding of dynamical phenomena, and engineers in design and development departments using computer codes may check the results more easily by choosing models of different complexity for vibration and stress analysis.

    2009-09-01

    Recently, we have analysed epidemiological models of competing strains of pathogens and hence differences in transmission for first versus secondary infection due to interaction of the strains with previously aquired immunities, as has been described for dengue fever, known as antibody dependent enhancement (ADE). These models show a rich variety of dynamics through bifurcations up to deterministic chaos. Including temporary cross-immunity even enlarges the parameter range of such chaotic attractors, and also gives rise to various coexisting attractors, which are difficult to identify by standard numerical bifurcation programs using continuation methods. A combination of techniques, including classical bifurcation plots and Lyapunov exponent spectra has to be applied in comparison to get further insight into such dynamical structures. Especially, Lyapunov spectra, which quantify the predictability horizon in the epidemiological system, are computationally very demanding. We show ways to speed up computations of such Lyapunov spectra by a factor of more than ten by parallelizing previously used sequential C programs. Such fast computations of Lyapunov spectra will be especially of use in future investigations of seasonally forced versions of the present models, as they are needed for data analysis.

  18. Epidemiology of gastric cancer

    2006-01-01

    The incidence and mortality of gastric cancer have fallen dramatically in US and elsewhere over the past several decades. Nonetheless, gastric cancer remains a major public health issue as the fourth most common cancer and the second leading cause of cancer death worldwide. Demographic trends differ by tumor location and histology. While there has been a marked decline in distal, intestinal type gastric cancers, the incidence of proximal, diffuse type adenocarcinomas of the gastric cardia has been increasing, particularly in the Western countries. Incidence by tumor sub-site also varies widely based on geographic location, race, and socioeconomic status. Distal gastric cancer predominates in developing countries, among blacks, and in lower socioeconomic groups, whereas proximal tumors are more common in developed countries, among whites, and in higher socio-economic classes. Diverging trends in the incidence of gastric cancer by tumor location suggest that they may represent two diseases with different etiologies. The main risk factors for distal gastric cancer include Helicobacter pylori (H pylori) infection and dietary factors, whereas gastroesophageal reflux disease and obesity play important roles in the development of proximal stomach cancer. The purpose of this review is to examine the epidemiology and risk factors of gastric cancer, and to discuss strategies for primary prevention.

    2014-12-01

    Major injury is the sixth leading cause of death worldwide. Among those under 35 years of age, it is the leading cause of death and disability. Traffic accidents alone are the main cause, fundamentally in low- and middle-income countries. Patients over 65 years of age are an increasingly affected group. For similar levels of injury, these patients have twice the mortality rate of young individuals, due to the existence of important comorbidities and associated treatments, and are more likely to die of medical complications late during hospital admission. No worldwide, standardized definitions exist for documenting, reporting and comparing data on severely injured trauma patients. The most common trauma scores are the Abbreviated Injury Scale (AIS), the Injury Severity Score (ISS) and the Trauma and Injury severity Score (TRISS). Documenting the burden of injury also requires evaluation of the impact of post-trauma impairments, disabilities and handicaps. Trauma epidemiology helps define health service and research priorities, contributes to identify disadvantaged groups, and also facilitates the elaboration of comparable measures for outcome predictions.

    2016-01-01

    Shigellosis is one of the major causes of diarrhoea in India. The accurate estimates of morbidity and mortality due to shigellosis are lacking, though it is endemic in the country and has been reported to cause many outbreaks. The limited information available indicates Shigella to be an important food-borne pathogen in India. S. flexneri is the most common species, S. sonnei and non-agglutinable shigellae seem to be steadily surfacing, while S. dysenteriae has temporarily disappeared from the northern and eastern regions. Antibiotic-resistant strains of different Shigella species and serotypes have emerged all over the world. Especially important is the global emergence of multidrug resistant shigellae, notably the increasing resistance to third generation cephalosporins and fluoroquinolones, and also azithromycin. This calls for a continuous and strong surveillance of antibiotic resistance across the country for periodic updation of the local antibiograms. The prevention of shigellosis is desirable as it will substantially reduce the morbidity associated with diarrhoea in the country. Public health measures like provision of safe water and adequate sanitation are of immense importance to reduce the burden of shigellosis, however, the provision of resources to develop such an infrastructure in India is a complex issue and will take time to resolve. Thus, the scientific thrust should be focused towards development of a safe and affordable multivalent vaccine. This review is focused upon the epidemiology, disease burden and the therapeutic challenges of shigellosis in Indian perspective. PMID:27487999

    2010-01-01

    Corporate responses to illness is currently an ad-hoc, subjective process that has little basis in data on how disease actually spreads at the workplace. Additionally, many studies have shown that productivity is not an individual factor but a social one: in any study on epidemic responses this social factor has to be taken into account. The barrier to addressing this problem has been the lack of data on the interaction and mobility patterns of people in the workplace. We have created a wearable Sociometric Badge that senses interactions between individuals using an infra-red (IR) transceiver and proximity using a radio transmitter. Using the data from the Sociometric Badges, we are able to simulate diseases spreading through face-to-face interactions with realistic epidemiological parameters. In this paper we construct a curve trading off productivity with epidemic potential. We are able to take into account impacts on productivity that arise from social factors, such as interaction diversity and density, wh...

    Full Text Available Abstract Background This study aims to critically review available cost-effectiveness models for rotavirus vaccination, compare their designs using a standardized approach and compare similarities and differences in cost-effectiveness outcomes using a uniform set of input parameters. Methods We identified various models used to estimate the cost-effectiveness of rotavirus vaccination. From these, results using a standardized dataset for four regions in the world could be obtained for three specific applications. Results Despite differences in the approaches and individual constituting elements including costs, QALYs Quality Adjusted Life Years and deaths, cost-effectiveness results of the models were quite similar. Differences between the models on the individual components of cost-effectiveness could be related to some specific features of the respective models. Sensitivity analysis revealed that cost-effectiveness of rotavirus vaccination is highly sensitive to vaccine prices, rotavirus-associated mortality and discount rates, in particular that for QALYs. Conclusions The comparative approach followed here is helpful in understanding the various models selected and will thus benefit (low-income countries in designing their own cost-effectiveness analyses using new or adapted existing models. Potential users of the models in low and middle income countries need to consider results from existing studies and reviews. There will be a need for contextualization including the use of country specific data inputs. However, given that the underlying biological and epidemiological mechanisms do not change between countries, users are likely to be able to adapt existing model designs rather than developing completely new approaches. Also, the communication established between the individual researchers involved in the three models is helpful in the further development of these individual models. Therefore, we recommend that this kind of comparative study

    Case definitions are critical in epidemiologic research. However, modern disease indicators must now consider complex data from gene-based research along with traditional clinical parameters. Rosacea is a skin disorder with multiple signs and symptoms. In individuals, these features may be multiple or one may predominate. While studies on the epidemiology of rosacea have previously been sparse, there has been a recent increase in research activity. A broader body of epidemiological information that includes a greater variety of countries beyond Northern Europe and general population-based demographics is needed. As there are operational issues in current case definitions of rosacea subtypes--rationalization and standardization--universal consistent applications in future research is also imperative. Further improvement in disease definition combining new research information along with clinical pragmatism should increase the accuracy of rosacea case ascertainment and facilitate further epidemiological research.

    Full Text Available Structural equation modeling (SEM is an important statistical tool for evaluating complex relations in several research areas. In epidemiology, the use and discussion of SEM have been limited thus far. This article presents basic principles and concepts in SEM, including an application using epidemiological data analysis from a study on the determinants of cognitive development in young children, considering constructs related to organization of the child's home environment, parenting style, and the child's health status. The relations between the constructs and cognitive development were measured. The results showed a positive association between psychosocial stimulus at home and cognitive development in young children. The article presents the contributions by SEM to epidemiology, highlighting the need for an a priori theoretical model for improving the study of epidemiological questions from a new perspective.

    Farrington, D P; Loeber, R

    2000-10-01

    It is difficult to review the epidemiology of juvenile violence because few studies focus specifically on this topic as opposed to childhood aggression or delinquency in general. More research is needed specifically on juvenile violence, which is generally measured using official records or self-reports. Self-report research shows that a substantial fraction of the male juvenile population commits violence, and that very few violent acts are followed by arrests or convictions. Racial differences in violence may be explainable by reference to racial differences in community contexts. There is a great deal of versatility in juvenile violence. Juveniles who commit one type of violent offense also tend to commit other types and nonviolent offenses. Violent offenders tend to be persistent or frequent offenders, and there is little difference between violent offenders and nonviolent but equally frequent offenders. Nevertheless, there is some degree of specialization in violence. More research is needed to investigate whether risk factors exist for violence that are not risk factors for serious nonviolent delinquency (e.g., biologic factors). Violent juveniles tend to have co-occurring problems such as victimization, substance abuse, and school failure. Often, they might be described as multiple-problem youth. There is considerable continuity from childhood aggression to juvenile violence. An early age of onset of violence predicts a large number of violent offenses. The major long-term risk factors for juvenile violence are individual (high impulsiveness and low intelligence, possibly linked to the executive functions of the brain), family (poor supervision, harsh discipline, child physical abuse, a violent parent, large family size, poverty, a broken family), peer delinquency, gang membership, urban residence, and living in a high-crime neighborhood (characterized by gangs, guns, and drugs in the United States). More research is needed on interactions among risk factors

    Phenylketonuria newborn screening programs vary among different Latin American countries; each one has its own history; quality standards, newborn population covered and the mandatory legislation of newborn screening. Epidemiological knowledge on phenylketonuria of this region is imprecise due to the lack of national statistic registries, thus avoiding an objective assessment of population coverage and disease incidence; therefore available data is obtained from isolated observations. Analysis of phenylketonuria and hyperphenylalaninemia based on available information of several Latin American newborn screening programs shows mean incidence values of 1: 23,518 and 1: 20,759 respectively; however, individual analysis of incidence by country indicates that phenylketonuria ranges between 1:12,473 and 1:161,748 live newborns.

  19. Molecular Epidemiology for Vector Research on Leishmaniasis

    Directory of Open Access Journals (Sweden)

    Hirotomo Kato

    2010-03-01

    Full Text Available Leishmaniasis is a protozoan disease caused by the genus Leishmania transmitted by female phlebotomine sand flies. Surveillance of the prevalence of Leishmania and responsive vector species in endemic and surrounding areas is important for predicting the risk and expansion of the disease. Molecular biological methods are now widely applied to epidemiological studies of infectious diseases including leishmaniasis. These techniques are used to detect natural infections of sand fly vectors with Leishmania protozoa and are becoming powerful tools due to their sensitivity and specificity. Recently, genetic analyses have been performed on sand fly species and genotyping using PCR-RFLP has been applied to the sand fly taxonomy. In addition, a molecular mass screening method has been established that enables both sand fly species and natural leishmanial infections to be identified simultaneously in hundreds of sand flies with limited effort. This paper reviews recent advances in the study of sand flies, vectors of leishmaniasis, using molecular biological approaches.

    The aim of this study was to determine whether e-learning as a new teaching concept was acceptable for second-year undergraduates and to compare attitudes and exam results of students who followed electronic compared with classroom seminars. The electronic seminars (e-seminars) were developed several months prior to start of the epidemiology course for second-year students at the Faculty of Medicine, University of Belgrade. The students who applied for e-seminars accessed their content during summer semester (February-May) 2014. E-seminars were set according to the existing topics in practical workbook and designed using Moodle, a free, open-source, personal home page web application for producing modular internet-based courses. To evaluate the motives for enrollment and satisfaction with seminars, two surveys (pre- and post-course) were administered. Students' exam grades were registered over 4 exam sessions (June-October 2014) and compared according to seminar program. Out of 516 students in the second year, 60 (11.6 %) applied for e-seminars (mean age 21 years). Students considered the reason "It's easier to do assignments from home" as the strongest motive to participate. When compared to classroom seminars, students in e-seminars had significantly more fun (p = 0.003), thought that e-seminars were better mode to learn epidemiology (p = 0.030) and would recommend them to other colleagues (p = 0.001). There was no significant difference in average grade received at the oral exam in epidemiology (t = 0.071, p = 0.944). E-seminars in undergraduate epidemiology course add a novel, easy-to-follow and amusing mode of learning.

    Full Text Available The epidemiology of hepatitis C virus (HCV infection is not well defined in the Middle East region. A review of the epidemiology and modes of transmission and spread of HCV infection in regions located in the Middle East, including Iran, Bahrain, Iraq, Oman, Qatar, Jordan, Kuwait, Saudi Arabia, United Arab Emirates, Cyprus, Sudan, Egypt, Pakistan, Syria, Turkey, Lebanon, Gaza Strip and West Bank, and Yemen, was undertaken. Public health strategies, well-programmed, population-based and certain HCV infection at-risk surveys, and transmission risk factors′ settings detection are insufficient in some countries of this region. Since significant diffe-rences in prevalence and epidemiology of HCV exist among the Middle East countries or even inside the countries, control strategies should take these differences into account.

    Full Text Available Over the past 20 years, major progress has been made in our understanding of critical aspects of rabies epidemiology and control. This paper presents results of recent research, highlighting methodological advances that have been applied to burden of disease studies, rabies epidemiological modelling and rabies surveillance. These results contribute new insights and understanding with regard to the epidemiology of rabies and help to counteract misperceptions that currently hamper rabies control efforts in Africa. The conclusion of these analyses is that the elimination of canine rabies in Africa is feasible, even in wildlife-rich areas, through mass vaccination of domestic dogs and without the need for indiscriminate culling to reduce dog population density. Furthermore, the research provides valuable practical insights that support the operational planning and design of dog vaccination campaigns and rabies surveillance measures.

    Full Text Available A prerequisite of personalized medicine is the identification of groups of people who share specific risk factors towards an outcome. We investigate the potential of subspace clustering for finding such groups in epidemiological data. We propose a workflow that encompasses clusterability assessment before cluster discovery and quality assessment after learning the clusters. Epidemiological usually do not have a ground truth for the verification of clusters found in subspaces. Hence, we introduce quality assessment through juxtaposition of the learned models to “models-of-randomness”, i.e. models that do not reflect a true cluster structure. On the basis of this workflow, we select subspace clustering methods, compare and discuss their performance. We use a dataset with hepatic steatosis as outcome, but our findings apply on arbitrary epidemiological cohort data that have tenths of variables and exhibit class skew.

    Full Text Available BACKGROUND: Tinea versicolor is a chronic, mild, usually asymptomatic infection of the stratum corneum. The lesions are discrete or confluent and appear as discolored or hypo pigmented areas of the skin. The affected areas are located principally on the chest, abdomen, upper extremities and back. The etiologic agent is the lipophilic yeast Pityrosporum orbiculare, part of the normal flora of the human skin. This study is undertaken to know “clinical, patterns of the disease with respect to morphology and distribution, associated conditions and epidemiological factors like age, sex distribution and seasonal variation of the disease”. METHODS: Two hundred patients of tinea versicolor were selected. Patients belonging to the age group of above 10 years and below 60 years belonging to both sexes were selected and included in the study group after taking consent. A detailed history was taken with particular reference to onset, duration, symptoms and treatment taken and were recorded. Factors like – seasonal variation, family history and presence of any associated illnesses was also noted. A thorough clinical examination was done with reference to the location, the color, the extent of the lesions, the margins, the type of lesions and the details were recorded. Potassium hydroxide (KOH examination and Wood’s lamp examination were done in all the patients before therapy. RESULTS: Out of 200 patients, majority of them belong to 2nd and 3rd decade of life (72%. The Male: Female ratio was 1.5:1. There was a family history of 16%. The trunk was the most common site involved. Majority of the patients had exacerbation in summer. The most common associated dermatoses were acne vulgaris, immunosuppression and infections. INTERPRETATION AND CONCLUSION: Tinea versicolor is a disease of worldwide distribution, although it is significantly more common in humid and tropical climates. The true incidence cannot be estimated precisely because the disease is

    Mercury Cadmium Telluride (MCT) detectors provide excellent sensitivity to infrared radiation and are used in passive infrared remote sensors such as the Atmospheric Emitted Radiance Interferometer (AERI). However, MCT detectors have a nonlinear response and thus this nonlinearity must be characterized and corrected to provide accurate infrared radiance observations. This paper discusses the significance of the nonlinearity correction applied to AERI data and its impacts on the parameters retrieved from the AERI spectra. It also evaluates the accuracy of the scheme used to determine the nonlinearity of the MCT detectors used in the Atmospheric Radiation Measurement (ARM) Program’s AERIs.

    In response to the need for improved observations of environmental factors to better understand the links between human health and the environment, NASA has established a new program to significantly improve the utilization of NASA's diverse array of data, information, and observations of the Earth for health applications. This initiative, lead by Goddard Space Flight Center (GSFC) has the following goals: (1) To encourage interdisciplinary research on the relationships between environmental parameters (e.g., rainfall, vegetation) and health, (2) Develop practical early warning systems, (3) Create a unique system for the exchange of Earth science and health data, (4) Provide an investigator field support system for customers and partners, (5) Facilitate a system for observation, identification, and surveillance of parameters relevant to environment and health issues. The NASA Environment and Health Program is conducting several interdisciplinary projects to examine applications of remote sensing data and information to a variety of health issues, including studies on malaria, Rift Valley Fever, St. Louis Encephalitis, Dengue Fever, Ebola, African Dust and health, meningitis, asthma, and filariasis. In addition, the NASA program is creating a user-friendly data system to help provide the public health community with easy and timely access to space-based environmental data for epidemiological studies. This NASA data system is being designed to bring land, atmosphere, water and ocean satellite data/products to users not familiar with satellite data/products, but who are knowledgeable in the Geographic Information Systems (GIS) environment. This paper discusses the most recent results of the interdisciplinary environment-health research projects and provides an analysis of the usefulness of the satellite data to epidemiological studies. In addition, there will be a summary of presently-available NASA Earth science data and a description of how it may be obtained.

  9. Morphometrics applied to medical entomology.

    Dujardin, Jean-Pierre

    2008-12-01

    Morphometrics underwent a revolution more than one decade ago. In the modern morphometrics, the estimate of size is now contained in a single variable reflecting variation in many directions, as many as there are landmarks under study, and shape is defined as their relative positions after correcting for size, position and orientation. With these informative data, and the corresponding software freely available to conduct complex analyses, significant biological and epidemiological features can be quantified more accurately. We discuss the evolutionary significance of the environmental impact on metric variability, mentioning the importance of concepts like genetic assimilation, genetic accommodation, and epigenetics. We provide examples of measuring the effect of selection on metric variation by comparing (unpublished) Qst values with corresponding (published) Fst. The primary needs of medical entomologists are to distinguish species, especially cryptic species, and to detect them where they are not expected. We explain how geometric morphometrics could apply to these questions, and where there are deficiencies preventing the approach from being utilized at its maximum potential. Medical entomologists in connection with control programs aim to identify isolated populations where the risk of reinfestation after treatment would be low ("biogeographical islands"). Identifying them can be obtained from estimating the number of migrants per generation. Direct assessment of movement remains the most valid approach, but it scores active movement only. Genetic methods estimating gene flow levels among interbreeding populations are commonly used, but gene flow does not necessarily mean the current flow of migrants. Methods using the morphometric variation are neither suited to evaluate gene flow, nor are they adapted to estimate the flow of migrants. They may provide, however, the information needed to create a preliminary map pointing to relevant areas where one could

  11. Viral marketing as epidemiological model

    CERN Document Server

    Rodrigues, Helena Sofia

    2015-01-01

    In epidemiology, an epidemic is defined as the spread of an infectious disease to a large number of people in a given population within a short period of time. In the marketing context, a message is viral when it is broadly sent and received by the target market through person-to-person transmission. This specific marketing communication strategy is commonly referred as viral marketing. Due to this similarity between an epidemic and the viral marketing process and because the understanding of the critical factors to this communications strategy effectiveness remain largely unknown, the mathematical models in epidemiology are presented in this marketing specific field. In this paper, an epidemiological model SIR (Susceptible- Infected-Recovered) to study the effects of a viral marketing strategy is presented. It is made a comparison between the disease parameters and the marketing application, and simulations using the Matlab software are performed. Finally, some conclusions are given and their marketing impli...

  13. Comparison of two non-convex mixed-integer nonlinear programming algorithms applied to autoregressive moving average model structure and parameter estimation

    Science.gov (United States)

    Uilhoorn, F. E.

    2016-10-01

    In this article, the stochastic modelling approach proposed by Box and Jenkins is treated as a mixed-integer nonlinear programming (MINLP) problem solved with a mesh adaptive direct search and a real-coded genetic class of algorithms. The aim is to estimate the real-valued parameters and non-negative integer, correlated structure of stationary autoregressive moving average (ARMA) processes. The maximum likelihood function of the stationary ARMA process is embedded in Akaike's information criterion and the Bayesian information criterion, whereas the estimation procedure is based on Kalman filter recursions. The constraints imposed on the objective function enforce stability and invertibility. The best ARMA model is regarded as the global minimum of the non-convex MINLP problem. The robustness and computational performance of the MINLP solvers are compared with brute-force enumeration. Numerical experiments are done for existing time series and one new data set.

    Stomach cancer is the one of the leading cause of cancer in southern region of India. Its incidence is decreasing worldwide yet on global scale stomach cancer remains one of the most common causes of cancer death. Etiology of gastric cancer includes Helicobacter pylori infection, diet and lifestyle, tobacco, alcohol and genetic susceptibility. In this review, we tried to find the contribution of Indian scientist in understanding the descriptive and observational epidemiology of stomach cancer. PubMed was used as a search platform using key words such as "stomach cancer, treatment, clinical characteristics, stomach cancer outcome, epidemiology, etiological factor and their corresponding Mesh terms were used in combination with Boolean operators OR, AND". Most of the reported studies on gastric cancer from India are case report or case series and few are case-control studies. Indian studies on this topic are limited and have observed H. pylori infection, salted tea, pickled food, rice intake, spicy food, soda (additive of food), tobacco and alcohol as risk factors for gastric cancer. More research is required to understand the etiology, develop suitable screening test, to demarcate high-risk population and to develop and evaluate the effect of primary prevention programs.

    A total of 5,758 tuberculosis cases were notified in France in 2008, giving a rate of nine cases per 100,000 inhabitants. The median age was 45 years and 59% of cases were male patients. Île-de-France (Paris and greater Paris area) and French Guiana had the highest notification rate in 2008 (17.9/10(5) and 22.6/10(5) respectively). The rate of tuberculosis was higher in individuals born abroad (43.2/10(5) vs. 5.0/10(5) for individuals born in France), especially those recently arrived in France. Pulmonary tuberculosis accounted for 72% of notified cases, 76% of which were potentially contagious (positive sputum smear, or culture). Compared to 2007, the number of notified tuberculosis cases increased by 3.3% in 2008. This increase was not accompanied by a rise of severe cases (meningitis and miliary TB); this seemed to be due partly to improvement in identification and notification of cases. However this trend could require specific monitoring in future years. A national tuberculosis control program was launched in France in 2007, aiming at reducing epidemiological disparities. Clinical and public health expertise needs to be maintained on all the territory to ensure that implemented measures can have the expected impact on the epidemiology of the disease.

    2014-01-01

    Models of epidemics in complex networks are improving our predictive understanding of infectious disease outbreaks. Nonetheless, applying network theory to plant pathology is still a challenge. This overview summarizes some key developments in network epidemiology that are likely to facilitate its application in the study and management of plant diseases. Recent surveys have provided much-needed datasets on contact patterns and human mobility in social networks, but plant trade networks are still understudied. Human (and plant) mobility levels across the planet are unprecedented-there is thus much potential in the use of network theory by plant health authorities and researchers. Given the directed and hierarchical nature of plant trade networks, there is a need for plant epidemiologists to further develop models based on undirected and homogeneous networks. More realistic plant health scenarios would also be obtained by developing epidemic models in dynamic, rather than static, networks. For plant diseases spread by the horticultural and ornamental trade, there is the challenge of developing spatio-temporal epidemic simulations integrating network data. The use of network theory in plant epidemiology is a promising avenue and could contribute to anticipating and preventing plant health emergencies such as European ash dieback.

    In February 1985 a small international meeting of scientists took place at the recreation resort of the Polish Academy of Sci­ ences in Mogilany, near Cracow, Poland. The initiative for holding the workshop came from a working meeting on mathematical immunology and related topics at the International Institute for Applied Sys­ tems Analysis in Laxenburg, Austria, in November 1983. In addition to representatives of IIASA, delegates of the IIASA National Member Organizations (NMO) of Czechoslovakia, Italy, and the soviet Union took part in that working meeting. The participants came to the conclusion that IIASA could play an important role in facilitating the development of research in this field. The first step that they recommended to I IASA was to organize a workshop on mathematical immunology. The purpose of the workshop was to review the progress that has been made in applying mathematics to problems in immunology and to explore ways in which further progress might be achieved, especially by more efficie...

    Scholars have argued that theoretical insights of critical medical anthropology should be applied to the analysis of complementary and alternative medicine in order to develop more criticaly engaged integrative medicine. In this essay we focus on nature cure in the context of India’s contemporary epidemiological transition as an example of why engaged integrative medicine is important for public health, and how the institutionalization of nature cure treatment in India provides a critical framework for the development of programs focused on holistic treatment and prevention. After providing an overview of the epidemiological transition in contemporary India, we develop this argument through an examination of ilustrative cases in a clinic that operates within the structure of India’s Central Council for Research on Yoga and Naturopathy. Based on a review of recent history and contemporary practice we describe how a system of medicine that makes use exclusively of air, earth, sunlight, water and food has been institutionalized and professionalized in India. Whereas biomedical treatment for chronic non-communicable diseases is focused on the problem of curing individual diseases, nature cure establishes a regimen of personalized public healthcare for the integrated management of symptoms. We argue that nature cure is based on an ecological understanding of health, thus providing treatment that refl ects a broad appreciation for the risk factors that characterize India’s current crises of public health.

This work aimed to improve the AOCS Ce 1j-07 Method for the FA composition of a mixture of soybean and sunflower oil, fish oil, and butterfat, using a modified temperature program, tested among five laboratories. It takes more time, but it allows to completely separate butyric acid from the solvent, trans-18:1 from cis-18:1, 20:1 isomers from 18:3 n-3, 22:1 n-9 from 20:4 n-6, 20:5 n-3 from 24:0 and the main CLA isomers, thus permitting FA quantification in fats and oils for different purposes such as nutritional labeling, quality control and research.Métodos por cromatografía gas-líquido, AOAC 966.06 (2005, AOCS Ce 1h-05 (2005, Ce 1j-07 (2007 permiten determinar ácidos grasos (AG en matrices grasas usando columnas capilares altamente polares y distintos programas de temperatura. No obstante, aún existen dificultades para separar ácido butírico del solvente, pares críticos de AG con polaridades similares, isómeros del ácido linoleico conjugado (CLA, AG de cadena larga poliinsaturados (LC-PUFAs. El objetivo fue mejorar el Método AOCS Ce 1j-07 aplicándolo a la composición en AG de mezcla de aceite soja/girasol, aceite de pescado, mantequilla, usando un programa de temperatura modificado, entre cinco laboratorios. El programa de temperatura elegido, si bien emplea más tiempo, permite separar completamente ácido butírico del solvente, trans-18:1 de cis-18:1, isómeros 20:1 de 18:3 n-3, 22:1 n-9 de 20:4 n-6

    Full Text Available La neurocisticercosis, infección del sistema nervioso humano por el estadio larvario de la Taenia solium, es una causa importante de epilepsia y otras manifestaciones neurológicas en el Perú y en la mayoría de países en desarrollo. Desde 1987, el Grupo de Trabajo en Cisticercosis en Perú ha desarrollado una serie de estudios epidemiológicos que han llevado a estimar el impacto y entender la transmisión de la Taenia solium, y que posteriormente se aplicaron al diseño y ejecución de un programa de control en Tumbes, en la costa norte del país. En este artículo se revisan los principales hallazgos epidemiológicos, así como las líneas generales del programa de eliminación y las herramientas utilizadas. Los avances en el control de la teniasis/cisticercosis en nuestro país abren el camino hacia su eliminación y eventual erradicación.Neurocysticercosis, the infection of the human central nervous system by the larval stage of the cestode Taenia solium, is an important cause of epilepsy and other neurological manifestations in Peru and most developing countries. Since 1987, the Cysticercosis Working Group in Peru has performed a series of epidemiological studies which led to estimate the impact and to better understand the transmission of Taenia solium. This information was later applied to the design and execution of a control program in Tumbes, in the Northern Coast of Peru. This paper reviews the main epidemiological findings, as well as the conceptual framework of the elimination program and the tools used. Advances in the control of taeniasis/cysticercosis in our country open the road towards its elimination and potential eradication.

  11. Applied survival analysis using R

    CERN Document Server

    Moore, Dirk F

    2016-01-01

    Applied Survival Analysis Using R covers the main principles of survival analysis, gives examples of how it is applied, and teaches how to put those principles to use to analyze data using R as a vehicle. Survival data, where the primary outcome is time to a specific event, arise in many areas of biomedical research, including clinical trials, epidemiological studies, and studies of animals. Many survival methods are extensions of techniques used in linear regression and categorical data, while other aspects of this field are unique to survival data. This text employs numerous actual examples to illustrate survival curve estimation, comparison of survivals of different groups, proper accounting for censoring and truncation, model variable selection, and residual analysis. Because explaining survival analysis requires more advanced mathematics than many other statistical topics, this book is organized with basic concepts and most frequently used procedures covered in earlier chapters, with more advanced topics...

  19. Epidemiology of Rhodococcus equi infection in horses.

    Science.gov (United States)

    Prescott, J F

    1987-08-01

    Current understanding of the epidemiology of Rhodococcus equi infection on horse farms is reviewed. Infection is widespread in herbivores and their environment, because herbivore manure supplies the simple organic acid substrates on which the organism thrives. There is a progressive development of infection in the soil on horse farms with prolonged use, because: (1) there is a continual supply of nutrients; (2) the organism multiplies progressively as temperatures rise; (3) the bacterium has a robust nature. While this aerobic organism fails to multiply in the largely anaerobic intestine of the adult horse, multiplication to very large numbers may occur in the intestine of a foal in its first 8-12 weeks of life. Farms used for foal breeding over many years may thus become particularly dangerous for foals. Areas for future study include the effectiveness of decontamination, manure-removal programs and dust reduction in reducing challenge to susceptible foals.

    Epidemiologic studies in inflammatory bowel disease (IBD) include assessments of disease burden and evolving patterns of disease presentation. Although it is hoped that sound epidemiologic studies provide aetiological clues, traditional risk factor-based epidemiology has provided limited insights into either Crohn\\'s disease or ulcerative colitis etiopathogenesis. In this update, we will summarize how the changing epidemiology of IBD associated with modernization can be reconciled with current concepts of disease mechanisms and will discuss studies of clinically significant comorbidity in IBD.

  2. Travel epidemiology: the Saudi perspective.

    2003-02-01

    The Kingdom of Saudi Arabia occupies four-fifths of the Arabian Peninsula, with a land area of 2 million square kilometres. Saudi Arabia holds a unique position in the Islamic world, as the custodian of the two holiest places of Islam, in Mecca and Medina. Annually, some 2 million Muslims from over 140 countries embark on Hajj. This extraordinary en masse migration is a unique forum for the study of travel epidemiology since the Hajj carries various health risks, both communicable and non-communicable, often on a colossal scale. Non-communicable hazards of the Hajj include stampede and motor vehicle trauma, fire-related burn injuries and accidental hand injury during animal slaughter. Communicable hazards in the form of outbreaks of multiple infectious diseases have been reported repeatedly, during and following the Hajj. Meningococcal meningitis, gastroenteritis, hepatitis A, B and C, and various zoonotic diseases comprise some of the possible infectious hazards at the Hajj. Many of these infectious and non-infectious hazards can be avoided or averted by adopting appropriate prophylactic measures. Physicians and health personnel must be aware of these risks to appropriately educate, immunize and prepare these travellers facing the unique epidemiological challenges of Hajj in an effort to minimize untoward effects. Travel epidemiology related to the Hajj is a new and exciting area, which offers valuable insights to the travel specialist. The sheer scale of numbers affords a rare view of migration medicine in action. As data is continually gathered and both national and international policy making is tailored to vital insights gained through travel epidemiology, the Hajj will be continually safeguarded. Practitioners will gain from findings of travel related epidemiological changes in evolution at the Hajj: the impact of vaccinating policies, infection control policies and public health are afforded a real-world laboratory setting at each annual Hajj, allowing us to

  4. Construction of predictive models for radionuclide diffusion in sedimentary rocks applied to radioactive waste deep storage: approach and overview of the CEA research program

    International Nuclear Information System (INIS)

    Full text of publication follows: Deep geological storage is studied in France as one of the three potential options for managing long lived nuclear waste in the framework of the 1991 Law. One of the key topics of research deals with the behaviour of radionuclides in the geological environment, focusing in particular on the diffusion process within the rock. The final aim is to develop validated and reliable long-term predictive migration models. These researches are mainly coping with Jurassic-age Callovo-Oxfordian argilites. They include first some characterizations performed on core samples (diffusion tests, characterisation of porosity properties, chemical retention measurements). In fact, tests on small samples in diffusion cells under laboratory conditions are essential to obtain diffusion parameters used in safety calculations because they allow selection and control of experimental physical and chemical conditions and therefore constitute the principal tools for understanding and quantifying the underlying phenomena such as the effect of temperature, water composition, and lithological properties of the rocks. As a consequence, CEA performed for more than ten years several hundredths of through diffusion tests involving inert, anionic and cationic radioactive tracers on argilites and limestone samples. Tests conducted in diffusion cells do however have limitations because they apply to small samples. In addition, tests performed in surface laboratories are confronted with uncertainties relating to the determination of the in-situ water composition. Moreover, samples used in the surface laboratory may have been subjected to mechanical and chemical disturbances before the actual performance of the tests. It is therefore necessary to validate the extrapolation of the characterisation results of transport properties to larger scales. In-situ experiments help then in analysing the representativeness of physical models and associated parameters and support the

  6. Molecular Epidemiology of Brucella abortus in Northern Ireland-1991 to 2012.

    Directory of Open Access Journals (Sweden)

    Adrian Allen

    Full Text Available Brucellosis is the most common bacterial zoonoses worldwide. Bovine brucellosis caused by Brucella abortus has far reaching animal health and economic impacts at both the local and national levels. Alongside traditional veterinary epidemiology, the use of molecular typing has recently been applied to inform on bacterial population structure and identify epidemiologically-linked cases of infection. Multi-locus variable number tandem repeat VNTR analysis (MLVA was used to investigate the molecular epidemiology of a well-characterised Brucella abortus epidemic in Northern Ireland involving 387 herds between 1991 and 2012.MLVA identified 98 unique B. abortus genotypes from disclosing isolates in the 387 herds involved in the epidemic. Clustering algorithms revealed the relatedness of many of these genotypes. Combined with epidemiological information on chronology of infection and geographic location, these genotype data helped to identify 7 clonal complexes which underpinned the outbreak over the defined period. Hyper-variability of some VNTR loci both within herds and individual animals led to detection of multiple genotypes associated with single outbreaks. However with dense sampling, these genotypes could still be associated with specific clonal complexes thereby permitting inference of epidemiological links. MLVA- based epidemiological monitoring data were congruent with an independent classical veterinary epidemiology study carried out in the same territory.MLVA is a useful tool in ongoing disease surveillance of B. abortus outbreaks, especially when combined with accurate epidemiological information on disease tracings, geographical clustering of cases and chronology of infection.

  12. "Epidemiological criminology": coming full circle.

    Science.gov (United States)

    Akers, Timothy A; Lanier, Mark M

    2009-03-01

    Members of the public health and criminal justice disciplines often work with marginalized populations: people at high risk of drug use, health problems, incarceration, and other difficulties. As these fields increasingly overlap, distinctions between them are blurred, as numerous research reports and funding trends document. However, explicit theoretical and methodological linkages between the 2 disciplines remain rare. A new paradigm that links methods and statistical models of public health with those of their criminal justice counterparts is needed, as are increased linkages between epidemiological analogies, theories, and models and the corresponding tools of criminology. We outline disciplinary commonalities and distinctions, present policy examples that integrate similarities, and propose "epidemiological criminology" as a bridging framework.

    Some information on cancer in Malaysia are available, and its epidemiology is described. There is a need for systematic and coordinated collection of cancer statistics which are essential to patient management, cancer control programme formulation, implementation and evaluation. The decision of the Ministry of Health to introduce National Cancer Registry and to encourage epidemiological studies, which will ultimately lead to the utilization of data and introduction of control and preventive activities for cancers are positive steps in the right direction. Meanwhile, curative and palliative treatment is available from the existing hospital facilities, and preventive activities such as actions on smoking and health will be continued until such time when a comprehensive prevention and control programme for cancers in the country is evolved.

    1994-06-01

    Psoriasis is a genetically inherited spectrum of skin diseases characterized by epidermal proliferation and inflammation, which are reversible. Although many have reported that psoriasis is triggered by trauma, infections, stress, drugs, etc., the epidemiology of psoriasis remains poorly understood. Linkage to human leukocyte antigen-(HLA)-Cw6 and DR7 is strong in people with early onset disease, but concordance in monozygotic twins is only 67%, emphasizing the importance of a triggering event. Other factors that have been reported to affect the course of psoriasis include upper respiratory infections, smoking, obesity, alcohol ingestion, regional enteritis, and human immunodeficiency virus infection. This manuscript reviews the clinical epidemiology of psoriasis and highlights some of the needs for further investigation into specific areas of the disease.

    1993-12-01

    Aiming to describe the place that Chile has in the epidemiological transition, a descriptive study of the changes in demographic and epidemiological profiles of the country during the last 30 years is presented. The important decrease in general and child mortality rates, that has lead to an increase in life expectancy and ageing of the population, is emphasized. A 82% reduction in the proportion of deaths among less than one year old children and a 62% increase in mortality among people 65 years or older is observed. In agreement with these changes, non transmissible chronic diseases appear as the principal cause of mortality (65% of all deaths). However, regarding morbidity, an increase in digestive infectious and sexually transmitted diseases and a decrease in immuno-preventable diseases, excepting measles, is noted. It is concluded that, according to mortality, Chile is in a post transition stage, but there is persistence of some infectious diseases, typical of a pre-transition stage. PMID:8085073

    This article introduces the design, sampling, field procedures and instruments used in the ZInEP Epidemiology Survey. This survey is one of six ZInEP projects (Zürcher Impulsprogramm zur nachhaltigen Entwicklung der Psychiatrie, i.e. the "Zurich Program for Sustainable Development of Mental Health Services"). It parallels the longitudinal Zurich Study with a sample comparable in age and gender, and with similar methodology, including identical instruments. Thus, it is aimed at assessing the change of prevalence rates of common mental disorders and the use of professional help and psychiatric sevices. Moreover, the current survey widens the spectrum of topics by including sociopsychiatric questionnaires on stigma, stress related biological measures such as load and cortisol levels, electroencephalographic (EEG) and near-infrared spectroscopy (NIRS) examinations with various paradigms, and sociophysiological tests. The structure of the ZInEP Epidemiology Survey entails four subprojects: a short telephone screening using the SCL-27 (n of nearly 10,000), a comprehensive face-to-face interview based on the SPIKE (Structured Psychopathological Interview and Rating of the Social Consequences for Epidemiology: the main instrument of the Zurich Study) with a stratified sample (n = 1500), tests in the Center for Neurophysiology and Sociophysiology (n = 227), and a prospective study with up to three follow-up interviews and further measures (n = 157). In sum, the four subprojects of the ZInEP Epidemiology Survey deliver a large interdisciplinary database. PMID:24942564

    Eastwood, M R

    1975-01-01

    The epidemiological triad of host, agent and environment used conceptually in infectious disease may serve as a model for psychosomatic disorders, despite the involvement of many more variables. There are major problems with diagnosis and measurement, however, and the term "psychosomatic" has several meanings. The two main senses are "specific" psychosomatic disorders and an ecological view of illness. The association between psychiatric and physical disorder has been examined in a variety of settings and the findings have suggested that there is a positive relationship. Despite considerable methodological and sampling difficulties in epidemiological research into psychosomatic illness, recent efforts have been made to overcome these. The results of ecological studies appear to be more consistent that those dealing with "specific" psychosomatic disorders and suggest that man has a general psychophysical propensity to disease. Although physical and mental illness do seem to be intimately linked, the reasons for "vulnerability" to illness and "clustering" of illness are obscure. The clarification of these areas appears to be the main task ahead for epidemiology in the field of psychosomatic medicine. PMID:773850

    Full Text Available Understanding the etiology of a disease such as prostate cancer may help in identifying populations at high risk, timely intervention of the disease, and proper treatment. Biomarkers, along with exposure history and clinical data, are useful tools to achieve these goals. Individual risk and population incidence of prostate cancer result from the intervention of genetic susceptibility and exposure. Biochemical, epigenetic, genetic, and imaging biomarkers are used to identify people at high risk for developing prostate cancer. In cancer epidemiology, epigenetic biomarkers offer advantages over other types of biomarkers because they are expressed against a person’s genetic background and environmental exposure, and because abnormal events occur early in cancer development, which includes several epigenetic alterations in cancer cells. This article describes different biomarkers that have potential use in studying the epidemiology of prostate cancer. We also discuss the characteristics of an ideal biomarker for prostate cancer, and technologies utilized for biomarker assays. Among epigenetic biomarkers, most reports indicate GSTP1 hypermethylation as the diagnostic marker for prostate cancer; however, NKX2-5, CLSTN1, SPOCK2, SLC16A12, DPYS, and NSE1 also have been reported to be regulated by methylation mechanisms in prostate cancer. Current challenges in utilization of biomarkers in prostate cancer diagnosis and epidemiologic studies and potential solutions also are discussed.

  7. Systematics and epidemiology of trichinella.

    2006-01-01

    In this review, we describe the current knowledge on the systematics, ecology and epidemiology of Trichinella and trichinellosis, and the impact of recent research discoveries on the understanding of this zoonosis. The epidemiology of this zoonosis has experienced important changes over the past two decades, especially with regard to the importance of the sylvatic cycle and the sylvatic species. Outbreaks of trichinellosis due to Trichinella spiralis from domestic swine, while still frequent, increasingly are caused by other Trichinella spp. infecting hosts such as horses, dogs, wild boars, bears and walruses. The latter revelations have occurred as a result of a series of discoveries on the systematics of Trichinella spp., facilitated by new molecular tools. As a consequence, the genus is now composed of two clades, an encapsulated group (five species and three genotypes) and a non-encapsulated one (three species). This has sparked renewed investigations on the host range of these parasites and their epidemiological features. Most dramatic, perhaps, is the recognition that reptiles may also serve as hosts for certain species. This new knowledge base, in addition to having an important relevance for food safety policies and protection measures, is raising important questions on the phylogeny of Trichinella spp., the ecological characteristics of the species and their geographic histories. Answers to these questions may have great value for the understanding of the evolutionary biology for other parasitic helminths, and may increase the value of this genus as models for research on parasitism in general.

  11. Major depression epidemiology from a diathesis-stress conceptualization

    Directory of Open Access Journals (Sweden)

    Patten Scott B

    2013-01-01

    Full Text Available Abstract Background Major depression is a widely used diagnostic category but there is increasing dissatisfaction with its performance. The diathesis-stress model is an alternative approach that does not require the (sometimes arbitrary imposition of categories onto the spectrum of depressive morbidity. However, application of this model has not been well explored and its consistency with available epidemiologic data is uncertain. Methods Simulation provides an opportunity to explore these issues. In this study, a simulation model based on an intuitive representation of diathesis-stress interaction was developed. Both diathesis and stress were represented using continuous distributions, without categorization. A diagnostic threshold was then applied to the simulation output to create nominal categories and to explore their consistency with available information. Results An apparently complex epidemiologic pattern emerged from the diathesis-stress interaction when thresholds were applied: incidence was time dependent, recurrence depended on the number of past episodes, baseline symptoms were associated with an increased risk of subsequent episodes and the remission rate declined with increasing episode duration. Conclusions A diathesis-stress conceptualization coupled with application of a threshold-based diagnostic definition may explain several of the apparent complexities of major depression epidemiology. Some of these complexities may be artifacts of the nominal diagnostic approach. These observations should encourage an empirical exploration of whether diathesis-stress interactions provide a more parsimonious framework for understanding depression than current approaches.

    Full Text Available Despite only accounting for approximately 2% of all new primary cancer cases, renal cell carcinoma (RCC incidence has dramatically increased over time. Incidence rates vary greatly according to geographic areas, so that it is extremely likely that exogenous risk factors could play an important role in the development of this cancer. Several risk factors have been linked with RCC, including cigarette smoking, obesity, hypertension (and antihypertensive drugs, chronic kidney diseases (also dialysis and transplantation, as well as the use of certain analgesics. Furthermore, although RCC has not generally been considered an occupational cancer, several types of occupationally-derived exposures have been implicated in its pathogenesis. These include exposure to asbestos, chlorinated solvents, gasoline, diesel exhaust fumes, polycyclic aromatic hydrocarbons, printing inks and dyes, cadmium and lead. Finally, families with a predisposition to the development of renal neoplasms were identified and the genes involved discovered and characterized. Therefore, there are now four well-characterized, genetically determined syndromes associated with an increased incidence of kidney tumors, i.e., Von Hippel Lindau (VHL, Hereditary Papillary Renal Carcinoma (HPRC, Birt-Hogg-Dubé Syndrome (BHD, and Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC. This review will address present knowledge about the epidemiology, molecular epidemiology and risk factors of RCC.

    2016-01-01

    More than 250,000 new cases of primary malignant brain tumors are diagnosed annually worldwide, 77% of which are gliomas. A small proportion of gliomas are caused by the inheritance of rare high-penetrance genetic variants or high-dose radiation. Since 2009, inherited genetic variants in 10 regions near eight different genes have been consistently associated with glioma risk via genome-wide association studies. Most of these variants increase glioma risk by 20-40%, but two have higher relative risks. One on chromosome 8 increases risk of IDH-mutated gliomas sixfold and another that affects TP53 function confers a 2.5-fold increased risk of glioma. Functions of some of the other risk variants are known or suspected, but future research will determine functions of other risk loci. Recent progress also has been made in defining subgroups of glioma based on acquired alterations within tumors. Allergy history has been consistently associated with reduced glioma risk, though the mechanisms have not yet been clarified. Future studies will need to be large enough so that environmental and constitutive genetic risk factors can be examined within molecularly defined, etiologically homogeneous subgroups.

    1992-05-01

    Neoplasms of the thorax encompass those derived from the thoracic wall, trachea, mediastinum, lungs and pleura. They represent a wide variety of lesions including benign and malignant tumors arising from many tissues. The large surface area, 60 to 90 m{sup 2} in man, represented by the respiratory epithelium and associated thoracic structures are ideal targets for carcinogens carried by inspired air. The topic of discussion in this report is the epidemiology, etiology, and mechanisms of spontaneous intrathoracic neoplasia in animals and man. Much of what we know or suspect about thoracic neoplasia in animals has been extrapolated from experimentally-induced neoplasms.

    Full Text Available Psoriasis is a chronic inflammatory skin disorder affecting 1-3% of the population and psoriatic patients constitute 6-8% of the attendants of outpatient dermatology polyclinics. Though it is a common disease with well known clinical features, current studies have focused on the pathogenesis and the treatment of the disease while little research has focused on epidemiologic characteristics of the disease. The etiopathogenesis of psoriasis is related with immunologic, autoimmune, and genetic factors. Currently psoriasis has been considered as a disease spectrum or a systemic disease and there is a growing body of research on the pathogenesis, associating disorders and treatment of the disease.

    Full Text Available Venous thrombosis, including deep vein thrombosis and pulmonary embolism, is a common disease that frequently recurs. Recurrence can be prevented by anticoagulants, but this comes at the risk of bleeding. Therefore, assessment of the risk of recurrence is important to balance the risks and benefits of anticoagulant treatment. This review briefly outlines what is currently known about the epidemiology of recurrent venous thrombosis, and focuses in more detail on potential new risk factors for venous recurrence. The general implications of these findings in patient management are discussed.

    Many of the basic statistical methods used in epidemiology - regression, analysis of variance, and estimation of relative risk, for example - originally were developed for the genetic analysis of biometric data. The familiarity that many geneticists have with this methodology has helped geneticists to understand and accept genetic epidemiology as a scientific discipline. It worth noting, however, that most of the work in genetic epidemiology during the past decade has been devoted to linkage and other family studies, rather than to population-based investigations of the type that characterize much of mainstream epidemiology. 30 refs., 2 tabs.

    Full Text Available In this work an epidemiological analysis on tibial shaft fractures was performed. During four years, our service treated 179 fractures, 132 in male, 47 in female, aged 14 to 83 years. The 21 to 30-year-old patiens were the more injured. Of these, 120 were open and 59 close fractures of which prevailing cause was road traffic accident. The study based on patients promptuaries analyses and radiographs. The fractures occurred 97 times in the middle third (54.18%; 102 times (56.98% presented simple fragments, and 57 (31.38% oblique lines. We treated close and open fractures, respectively, 48 and 38 cases with plaster cast immobilization; 3 and 67 with external fixation after plaster cast immobilization; 5 and 12 with osteosynthesis by means of plate and screws, and 2 and 3 with external fixation only. In both close and open fractures, respectively, 7 and 20 cases of pseudarthrosis and 1 and 11 of infections have occurred. With the data obtained we verified an actual validity of the epidemiological studies as a contribution for better identifying lesions features and their treatment and complications. This allows proceedings and apprenticeship refinement.

    2013-10-01

    Epidemiology of acromegaly in Spain does not differ from that reported in other published series. Prevalence rate is approximately 60 cases per million, peak incidence occurs in middle age, more women are affected (61%), and there is a substantial delay between occurrence of the first symptoms and diagnosis. Studies REA (Spanish Acromegaly Registry) and OASIS analyzed the epidemiology, clinical characteristics, and management of the disease in Spain. Surgery, performed in more than 80% of patients, has been (and continues to be) the main treatment for the past four decades. In the past decade, however, more patients have received somatostatin analogs (SSAs) as first-line treatment. Use of radiation therapy has significantly decreased in recent decades. Somatostatin analogs (SSAs) are the most commonly used drugs, administered to 85% of patients; however, only 12%-15% continue on drug treatment alone. The surgical remission rate was 38.4% in the last decade, with a significant improvement over decades. Preoperative treatment with SSAs has no influence on surgical cure rates. Second-line therapies used after surgical failure in the past decade included SSAs in 49% of patients, repeat surgery in 27%, radiotherapy in 11%, pegvisomant in 15%, and dopamine agonists in 5%. Mean cost of acromegaly treatment was 9.668€ (data estimated in 2009 and adjusted in 2010), of which 71% was due to the cost of SSAs. Patients treated with pegvisomant have a more aggressive form of the disease and higher comorbidity rates.

  9. Epidemiology: second-rate science?

    Science.gov (United States)

    Parascandola, M

    1998-01-01

    In recent years epidemiology has come under increasing criticism in regulatory and public arenas for being "unscientific." The tobacco industry has taken advantage of this, insisting for decades that evidence linking cigarettes and lung cancer falls short of proof. Moreover, many epidemiologists remain unduly skeptical and self-conscious about the status of their own causal claims. This situation persists in part because of a widespread belief that only the laboratory can provide evidence sufficient for scientific proof. Adherents of this view erroneously believe that there is no element of uncertainty or inductive inference in the "direct observation" of the laboratory researcher and that epidemiology provides mere "circumstantial" evidence. The historical roots of this attitude can be traced to philosopher John Stuart Mill and physiologist Claude Bernard and their influence on modern experimental thinking. The author uses the debate over cigarettes and lung cancer to examine ideas of proof in medical science and public health, concluding that inductive inference from a limited sample to a larger population is an element in all empirical science.

    Echinococcoses are parasitic diseases of major public health importance globally. Human infection results in chronic disease with poor prognosis and serious medical, social and economic consequences for vulnerable populations. According to recent estimates, the geographical distribution of Echinococcus spp. infections is expanding and becoming an emerging and re-emerging problem in several regions of the world. Echinococcosis endemicity is geographically heterogeneous and over time it may be affected by global environmental change. Therefore, landscape epidemiology offers a unique opportunity to quantify and predict the ecological risk of infection at multiple spatial and temporal scales. Here, we review the most relevant environmental sources of spatial variation in human echinococcosis risk, and describe the potential applications of landscape epidemiological studies to characterise the current patterns of parasite transmission across natural and human-altered landscapes. We advocate future work promoting the use of this approach as a support tool for decision-making that facilitates the design, implementation and monitoring of spatially targeted interventions to reduce the burden of human echinococcoses in disease-endemic areas.

    2014-12-01

    Tremendous progress has been made globally to reduce the contribution of measles to the burden of childhood deaths and measles cases have dramatically decreased with increased two dose measles-containing vaccine coverage. As a result the Global Vaccine Action Plan, endorsed by the World Health Assembly, has targeted measles elimination in at least five of the six World Health Organisation Regions by 2020. This is an ambitious goal, since measles control requires the highest immunisation coverage of any vaccine preventable disease, which means that the health system must be able to reach every community. Further, while measles remains endemic in any country, importations will result in local transmission and outbreaks in countries and Regions that have interrupted local endemic measles circulation. One of the lines of evidence that countries and Regions must address to confirm measles elimination is a detailed description of measles epidemiology over an extended period. This information is incredibly valuable as predictable epidemiological patterns emerge as measles elimination is approached and achieved. These critical features, including the source, size and duration of outbreaks, the seasonality and age-distribution of cases, genotyping pointers and effective reproduction rate estimates, are discussed with illustrative examples from the Region of the Americas, which eliminated measles in 2002, and the Western Pacific Region, which has established a Regional Verification Commission to review progress towards elimination in all member countries.

    the activities already underway in Nuclear Physics and Engineering, and preserves the identities and focus of the various institutions involved. ADS related research and development is being pursued by IPEN (design calculation, development of an Alternative Concept for a Fast Energy Amplifier). Moreover, IPEN operates a small cyclotrons, CV-28. The IPEN CV-28 cyclotron is presently not operational, but suitable for R and D: it is a compact, isochronous, multi-particle radiation source where protons, deuterons, 3He++, and alpha particles can be accelerated with variable energies up to 24, 14, 36, and 28 MeV respectively. Finally, IPEN is also operating the Cyclone-30 from IBA which is dedicated to radioisotope production (201-Tl, 123-I, 67-Ga), an electron accelerator used in high social and economic impact projects (e.g., food irradiation), and a Van de Graaff capable to provide a 14 MeV neutron source. The Physics Institute of Sao Paulo University-IFUSP is implementing various R and D activities/projects, in areas such as nuclear reactions with heavy ions, nuclear structure, photo nuclear reactions, ion implantation, non destructive techniques using accelerators beams. These programs are centered on IFUSP facilities, i.e., a heavy ion electrostatic accelerator (PELLETRON), a linear accelerator (LINAC), and an electron accelerator (MICROTRON), as well as associated experimental facilities. The institute is also performing theoretical research on nuclear reactions of interest to ADS (spallation-cascade evaporation model). Given the outlined scenario, IPEN-IFUSP have identified the possibility to launch a program on the utilization of accelerators. This programs would have three main pillars: R and D in basic and applied nuclear physics and engineering (e.g., low energy cross sections nuclear reactions, charged particle activation analysis, hydrogen implantation for angular correlation studies, excitation function determination, helium embrittlement in structural

    The World Health Organization identifies suicide among the top 10 causes of death in many countries with an overall mortality rate of 16 per 100,000 inhabitants. Furthermore suicide attempts present a frequency 4-10 times greater than the suicidal events, representing also one of the main risk factors to lead to recurrent attempts of suicide. In 2008 the Autonomous Province of Trento launched a suicide prevention pogram called "Invitation to Life" which includes various interventions intended to counter the phenomenon of suicide in the region. Actually the epidemiological research upon the phenomenon of suicide in Trentino region is one of the main pillars of the project: it represents a fundamental requirement to identify risk and protective factors in the population in order to adopt more specific and effective preventive strategies. This article aims to present methods and instruments for epidemiological monitoring of suicide and attempted suicide which are applied in Trentino and to describe results after seven years from the beginning of the local prevention program "Invitation to life".

The main outcome was the reduction of infection rates by Trypanosam cruzi (etiological agent measured by serology, in those born after the intervention. The actions of Chagas' disease control programs were based on house spraying with insecticide with the objective of controlling the vector Triatoma infestans (intermediate hosts of T. cruzi. The epidemiological designs used were: 1 Quasi-experimental, conducted in 1987, when an area for comparison was available. The reduction of T. cruzi infection rates in the area where intervention had been carried out for 5 and 10 years was compared with those where there was no intervention (control. The program effectiveness was estimated by comparing the infection rates found in the study with those published by the Chagas' disease serological survey (1975-1980; 2 Panel study, conducted in one area with 13 years of intervention. The objectives were to investigate the T. cruzi infection transmission pattern in a cohort born after the intervention and to verify whether the duration of the program was a determinant factor in inducing change in the incidence. The reduction of T. cruzi infection rates was estimated from data collected on three separate occasions: a national serological survey (1975-80, a quasi-experimental study (1987 and the present investigation (1995; 3 Nested case-control, to evaluate the risk factors of T.cruzi infection, incorporated within a serological survey of school children, which was implemented by the National Health Foundation to evaluate the effectiveness of the Chagas' disease control program

    Pain disorders are extraordinarily prevalent throughout clinical medicine, and are highly co-morbid with various psychiatric disorders, particularly those including depression or anxiety. Assessment of such patients tends to be based on diagnostic criteria that may not reflect the complexity of the clinical problem and can result in prioritizing somatic aspects of painful syndromes at the expense of psychiatric aspects or, conversely, over-emphasize psychiatric aspects. In the first part of this overview we consider current nosological perspectives and their potential clinical consequences, epidemiological data that underscore the association of comorbid painful and affective or anxious syndromes, and consider the importance of psychiatric assessment and treatment of such patients. The major overlap between pain disorders and psychiatric disorders, as well as the unsatisfactory state of treatments available for chronic pain syndromes, encourage a comprehensive approach to assessing and clinically managing patients with chronic pain. Many programs for pain disorder patients offer narrowly specialized treatment options. To be preferred are multi-disciplinary teams with expertise in internal medicine, neurology, pain management, and rehabilitation, as well as psychology and psychiatry. In the second part of this overview, we propose that psychiatrists can serve a key role in leading comprehensive assessment and management of complex and challenging pain-psychiatric patients who are typically only partially responsive to available treatments.

    Full Text Available Introduction. Gastric cancer was the third most common cancer worldwide in 2000, accounting for approximately 876 000 new cases or 9% of the global cancer burden. Epidemiological characteristics As a result of changes in diet, the incidence of gastric cancer has decreased in most countries. Now days, consumption of fresh vegetables and fruits is increasing in regard to canned food. In addition to unhealthy diet, the main risk factors for gastric cancer are H. pylori infection, alcohol consumption, smoking, gastritis, stomach ulcer, gastrectomy, stomach polyposis, positive family history for gastric cancer, pernicious anemia and blood type A. Diet rich in vegetables and fruits, and reduced salt intake can prevent 65-75% of gastric cancer cases among nonsmokers. Prevention of Helicobacter pylori infection can also reduce the incidence of this malignant disease. .

    The FDI has shown considerable interest in the oral cancer and has in recent years arranged three symposia on the subject. The incidence of oral cancer shows marked geographic differences mostly depending upon environmental factors. In the present paper the epidemiology of oral cancer is illustrated by the relative frequency to total number of cancers and incidence rates from a number of countries. Canada has the highest rate of cancer of the vermilion border, which is extremely rare among dark-skinned people. Even within one country differences may be found, a fact which is illustrated by findings from Czechoslovakia and India. In most of the studies dealing with the etiology of oral cancer tobacco usage in its various forms is shown to be the outstanding factor.

  5. On the epidemiology of influenza

    2008-02-01

    Full Text Available Abstract The epidemiology of influenza swarms with incongruities, incongruities exhaustively detailed by the late British epidemiologist, Edgar Hope-Simpson. He was the first to propose a parsimonious theory explaining why influenza is, as Gregg said, "seemingly unmindful of traditional infectious disease behavioral patterns." Recent discoveries indicate vitamin D upregulates the endogenous antibiotics of innate immunity and suggest that the incongruities explored by Hope-Simpson may be secondary to the epidemiology of vitamin D deficiency. We identify – and attempt to explain – nine influenza conundrums: (1 Why is influenza both seasonal and ubiquitous and where is the virus between epidemics? (2 Why are the epidemics so explosive? (3 Why do they end so abruptly? (4 What explains the frequent coincidental timing of epidemics in countries of similar latitude? (5 Why is the serial interval obscure? (6 Why is the secondary attack rate so low? (7 Why did epidemics in previous ages spread so rapidly, despite the lack of modern transport? (8 Why does experimental inoculation of seronegative humans fail to cause illness in all the volunteers? (9 Why has influenza mortality of the aged not declined as their vaccination rates increased? We review recent discoveries about vitamin D's effects on innate immunity, human studies attempting sick-to-well transmission, naturalistic reports of human transmission, studies of serial interval, secondary attack rates, and relevant animal studies. We hypothesize that two factors explain the nine conundrums: vitamin D's seasonal and population effects on innate immunity, and the presence of a subpopulation of "good infectors." If true, our revision of Edgar Hope-Simpson's theory has profound implications for the prevention of influenza.

    The magnitude of the threat that violence and war pose to the health, the quality of life, and the very survival of humanity is obvious. A number of scientific disciplines have provided, each through its own methodology, insights into the causation, genesis, and dynamics of violence and war. Although epidemiological and psychological methodologies received priority, the multidisciplinary approach to this problem seems to be the most appropriate. This essay attempts to approach holistically the study of epidemiology of violence and war and the ways of preventing these severe problems of the contemporary society. Conceptual models of the causative mechanisms and dynamics of violence and war, mapping the various psychic, social, and environmental factors, are presented. These models, besides advancing abstract ideas, also provide a concrete framework for determining and exploring the interactions and dynamics of the factors and processes which lead to violence and war. The types of interventions outlined for control and prevention are intended to make an impact upon "critical points" within the dynamics of the process which produces violence and war, and are conceived to be implemented on both the national and international level. The importance of family, community, and school influences is considered, but the role of international organizations, including the United Nations, and other governmental and non-governmental organizations is also stressed. Discussion is focused on the factors which favour peace and hamper aggression, on "internationalization" and global society versus xenophobia and nationalism. The conclusions state that there is sufficient knowhow to devise and implement a reasonable and effective international programme for the control and prevention of violence and war, provided there is adequate public and political willingness and support.

  7. Review of epidemiologic studies at Los Alamos National Laboratory

    International Nuclear Information System (INIS)

    Epidemiologic studies at Los Alamos are directed toward understanding potential health risks associated with activities pertaining to national energy and defense needs. Currently this research focuses on evaluating the effects of plutonium exposure in man. The major programs consist of (1) epidemiologic studies of the incidence of disease and mortality among plutonium and other workers at six Department of Energy (DOE) contractor facilities (Los Alamos, Rocky Flats, Mound, Savannah River, Hanford, and Oak Ridge), and (2) measurement of plutonium and other radionuclides in human tissues. Currently, investigations of mortality for Pantex workers and the surrounding general population are also being conducted for DOE in support of an Environment Impact Statement. This paper places emphasis on the activities of the national epidemiologic study of plutonium workers. The purpose of the plutonium workers study is to: (1) investigate whether adverse health effects are associated with exposures to plutonium, (2) explore whether adverse health effects are associated with exposure to transuranic elements, other radioisotopes, and hazardous substances that are found in nuclear facilities making routine use of plutonium, and (3) to describe in detail the nature of such health effects should they be discovered

    Violence prevention policies should be based on information, follow-up, research, and analysis, all of which increase the chances of success and make it easier to evaluate interventions. This implies, in turn, that there is a need to create surveillance, research, and prevention models for violence within the sphere of public health and epidemiology, a task that constitutes an integral part of the Pan American Health Organization's Regional Plan of Action Health and Violence. This article describes the objectives of epidemiologic surveillance systems and explains their purpose and scope, along with the barriers that stand in the way of their implementation. It also examines a number of variables and their definitions, the types of analyses and reports that should be generated, and the decisions that can be made on the basis of these reports. Finally, it discusses ethical criteria and describes the experiences of the program known as Desarrollo, Seguridad y Paz (DESEPAZ) in Cali and Santa Fe de Bogota, Colombia, where an epidemiologic surveillance system against violence has been implemented.

    Determining the magnitude of the thalassemia problem in a country is important for implementing a national prevention and control program. In order to acquire accurate thalassemia prevalence data, the gene frequency of α- and β-thalassemia (α- and β-thal) in different regions of a country should be determined. The molecular basis of thalassemia in Cambodia was performed by polymerase chain reaction (PCR)-based techniques in a community-based cross-sectional survey of 1631 unrelated individuals from three regions, Battambang, Preah Vihear and Phnom Penh. Thalassemia mutations were detected in 62.7% of the three studied population of Cambodia. Hb E (HBB: c.79G > A) was the most common β-globin gene mutation with a frequency ranging from 0.139 to 0.331, while the most frequent α-globin gene mutation was the -α(3.7) (rightward) deletion (0.098-0.255). The other frequencies were 0.001-0.003 for β-thal, 0.008-0.011 for α-thal-1 (- -(SEA)), 0.003-0.008 for α-thal-2 [-α(4.2) (leftward deletion)], 0.021-0.044 for Hb Constant Spring (Hb CS, HBA2: c.427T > C) and 0.009-0.036 for Hb Paksé (HBA2: c.429A > T). A regional specific thalassemia gene frequency was observed. Preah Vihear had the highest prevalence of Hb E (55.9%), α-thal-2 (24.0%) and nondeletional α-thal (15.1%), whereas Phnom Penh had the lowest frequency of thalassemia genes. Interestingly, in Preah Vihear, the frequency of Hb Paksé was extremely high (0.036), almost equivalent to that of Hb CS (0.044). Our results indicate the importance of micromapping and epidemiology studies of thalassemia, which will assist in establishing the national prevention and control program in Cambodia. PMID:27117566

    Full Text Available Abstract Background Geographic Information Systems (GIS are powerful communication tools for public health. However, using GIS requires considerable skill and, for this reason, is sometimes limited to experts. Web-based GIS has emerged as a solution to allow a wider audience to have access to geospatial information. Unfortunately the cost of implementing proprietary solutions may be a limiting factor in the adoption of a public health GIS in a resource-constrained environment. Scalable Vector Graphics (SVG is used to define vector-based graphics for the internet using XML (eXtensible Markup Language; it is an open, platform-independent standard maintained by the World Wide Web Consortium (W3C since 2003. In this paper, we summarize our methodology and demonstrate the potential of this free and open standard to contribute to the dissemination of Expanded Program on Immunization (EPI information by providing interactive maps to a wider audience through the Internet. Results We used SVG to develop a database driven web-based GIS applied to EPI data from three countries of WHO AFRO (World Health Organization – African Region. The system generates interactive district-level country immunization coverage maps and graphs. The approach we describe can be expanded to cover other public health GIS demanding activities, including the design of disease atlases in a resources-constrained environment. Conclusion Our system contributes to accumulating evidence demonstrating the potential of SVG technology to develop web-based public health GIS in resources-constrained settings.

    This article examines and interprets the trends of epidemiological production in Brazil in the Public Health context. CAPES indicators from 2001 to 2006 were used as database. We analyzed 26 programs and select the 10 major ones to analyze their bibliographic production in indexed journals. It was observed that the total production of epidemiological articles accounted for 40% of production in Public Health and 55% of the production was published in international journals, especially Cadernos de Saúde Pública, Revista de Saúde Pública and Ciência & Saúde Coletiva. The most prevalent themes were public health nutrition, maternal and infant health and, infectious diseases, particularly AIDS. Environmental e worker's heath, oral health, violence and health of the elderly have been ratified as objects of study for the discipline, while meta-analysis and geoprocessing appear as a useful tool for health services. We conclude that the epidemiological production tends to increase in indexed publications, covering various topics and a wide spectrum of relevant issues to Brazilian health policy. PMID:20694320

    We revisit the parameter estimation framework for population biological dynamical systems, and apply it to calibrate various models in epidemiology with empirical time series, namely influenza and dengue fever. When it comes to more complex models like multi-strain dynamics to describe the virus-host interaction in dengue fever, even most recently developed parameter estimation techniques, like maximum likelihood iterated filtering, come to their computational limits. However, the first results of parameter estimation with data on dengue fever from Thailand indicate a subtle interplay between stochasticity and deterministic skeleton. The deterministic system on its own already displays complex dynamics up to deterministic chaos and coexistence of multiple attractors.

    Full Text Available Abstract All sciences make mistakes, and epidemiology is no exception. I have chosen 7 illustrative mistakes and derived 7 solutions to avoid them. The mistakes (Roman numerals denoting solutions are: 1. Failing to provide the context and definitions of study populations. (I Describe the study population in detail 2. Insufficient attention to evaluation of error. (II Don't pretend error does not exist. 3. Not demonstrating comparisons are like-for-like. (III Start with detailed comparisons of groups. 4. Either overstatement or understatement of the case for causality. (IV Never say this design cannot contribute to causality or imply causality is ensured by your design. 5. Not providing both absolute and relative summary measures. (V Give numbers, rates and comparative measures, and adjust summary measures such as odds ratios appropriately. 6. In intervention studies not demonstrating general health benefits. (VI Ensure general benefits (mortality/morbidity before recommending application of cause-specific findings. 7. Failure to utilise study data to benefit populations. (VII Establish a World Council on Epidemiology to help infer causality from associations and apply the work internationally. Analysis of these and other common mistakes is needed to benefit from the increasing discovery of associations that will be multiplying as data mining, linkage, and large-scale scale epidemiology become commonplace.

  16. Linking avian communities and avian influenza ecology in southern Africa using epidemiological functional groups.

    The ecology of pathogens, and particularly their emergence in multi-host systems, is complex. New approaches are needed to reduce superficial complexities to a level that still allows scientists to analyse underlying and more fundamental processes. One promising approach for simplification is to use an epidemiological-function classification to describe ecological diversity in a way that relates directly to pathogen dynamics. In this article, we develop and apply the epidemiological functional group (EFG) concept to explore the relationships between wild bird communities and avian influenza virus (AIV) in three ecosystems in southern Africa. Using a two year dataset that combined bird counts and bimonthly sampling for AIV, we allocated each bird species to a set of EFGs that captured two overarching epidemiological functions: the capacity of species to maintain AIV in the system, and their potential to introduce the virus. Comparing AIV prevalence between EFGs suggested that the hypothesis that anseriforms (ducks) and charadriiforms (waders) drive AIV epidemiology cannot entirely explain the high prevalence observed in some EFGs. If anseriforms do play an important role in AIV dynamics in each of the three ecosystems, the role of other species in the local maintenance of AIV cannot be ruled out. The EFG concept thus helped us to identify gaps in knowledge and to highlight understudied bird groups that might play a role in AIV epidemiology. In general, the use of EFGs has potential for generating a range of valuable insights in epidemiology, just as functional group approaches have done in ecology. PMID:23101696

    Seidler, Andreas; Nienhaus, Albert; Diel, Roland

    2005-01-01

    This review summarizes the epidemiological evidence for occupationally acquired tuberculosis and considers the implications for the prevention of tuberculosis. The relevant epidemiological studies were identified on the basis of the Medline data bank, starting with the year 1966. The evaluation of occupational groups with an elevated tuberculosis risk is exclusively based on epidemiologic studies of good or acceptable quality, applying clearly defined criteria of methodological quality. In summary, the available epidemiological evidence suggests that the risk of tuberculosis is elevated in the following occupational groups: hospital employees in wards with tuberculosis patients; nurses in hospitals; nurses attending HIV-positive or drug-addicted patients; pathology and laboratory workers; respiratory therapists and physiotherapists; physicians in internal medicine, anaesthesia, surgery and psychiatry; non-medical hospital personnel in housekeeping and transport work; funeral home employees, and prison employees. However, the epidemiological evidence is limited for all these occupations, with the exception of the nurses, because of the lack of methodologically adequate studies that have got the statistical power to differentiate between specific work tasks. There is a need for large population-based studies with precise definition of exposure, which should include molecular epidemiologic methods in the investigation of occupational risk factors of tuberculosis.
