    Nuclear waste usually concerns public about the impact on public health and the environment. In Mexico, such interest exists, particularly in the Temascalapa Municipality, Mexico where a low level waste repository recognized by the IAEA, has been functioning since 1972. Maquixco repository is located at 42 Kilometers northeast of Mexico City. Although the environmental radiological monitoring records have demonstrated negligible impact on the environment, in 1998 an unusual public polemic on radioactive health effects appeared among Temascalapa residents. This paper presents a research performed during 1998 with the participation of the National Nuclear Research Institute of Mexico and the National Autonomous University of Mexico. The research design allowed the involvement of local authorities, as a way of stimulate public participation. The research was performed in nine locations of the Temascalapa Municipality, it was focused on public polemics, associated to Maquixco repository as well as trying to identify demographic factors that exert influence on public attitudes. There are also presented the results of personal dosimetry analysis performed on a four hundred residents sample of this Municipality. (Author)

    Full Text Available Este trabajo describe las funciones y utilidades de la implementación de perfiles de autor en repositorios institucionales, como un servicio de valor agregado dirigido a acrecentar su uso entre los miembros de una institución y mejorar la visibilidad de la producción científica alojada en el repositorio. Incluye un relevamiento de servicios de perfiles de autor implementados en repositorios institucionales argentinos y extranjeros. Advierte que, ante el establecimiento de mandatos nacionales de depósito, la necesidad de contar con repositorios institucionales fuertes y sostenibles en el tiempo es aún mayor que antes. Integrar a los repositorios las funcionalidades de los sistemas curriculares y de gestión de información científica y tecnológica es un camino para lograr esa fortaleza, y los perfiles de autor son el resultado visible de dicha integración. Señala que el beneficio que representa para un autor contar con un perfil público en el repositorio de su institución es equivalente al beneficio que para una institución representa contar con un repositorio digital, en términos de ventaja competitiva, valor añadido, incremento de la visibilidad y facilidades de recuperación y acceso a la producción generada.

    Full Text Available El presente estudio se centra en los repositorios institucionales universitarios como instrumentos que posibilitan el acceso en abierto a la producción científica y académica. Se analizan los Top50 repositorios universitarios europeos diferenciando, en primer lugar, aquellos repositorios vinculados a universidades españolas frente a los pertenecientes a universidades del resto de Europa y, en segundo lugar, los repositorios que incluyen en sus contenidos exclusivamente resultados de investigación frente a aquéllos que también albergan recursos docentes. En concreto, este trabajo complementa estudios previos sobre la consolidación de los repositorios, profundizando en el análisis del entorno competitivo a partir de sus cuotas relativas de participación y de visibilidad web. El análisis efectuado, a través del diseño de mapas competitivos y la aplicación del método de la ventaja relativa, permite identificar los repositorios universitarios europeos líderes en sus segmentos respecto a sus niveles de participación y visibilidad web en el mercado. A nivel general, sin establecer diferencias por segmentos, los resultados muestran que el liderazgo a nivel europeo, en términos de participación, lo ostenta el University College of London (Reino Unido, mientras que el repositorio de la Universidad de Umea (Suecia es líder en visibilidad.

    Full Text Available La producción académica de estudiantes en una institución educativa reúne resultados de investigaciones actuales y originales de diversas temáticas. Hoy en día podemos encontrar repositorios de tesis digitales en Internet disponibles para su consulta. Se han hecho esfuerzos por estandarizar dichos repositorios para establecer interoperabilidad entre diferentes instituciones; Sin embargo estos esfuerzos se centran más en la recuperación de información que en la recomendación de contenido. El modelo que se propone es una solución para la búsqueda, recuperación y recomendación de trabajos de titulación en una institución educativa, personalizando la recuperación de información utilizando filtrados por contenido y colaborativo. El sistema de recomendación resultante, producto de esta investigación, se espera facilite el acceso de forma particular a los trabajos de titulación del área de ciencias sociales tanto a profesores como estudiantes permitiendo realizar consultas sobre temas específicos, recuperando la información solicitada y personalizándola de acuerdo al perfil de usuario construido con base en su interacción con el sistema.

    Full Text Available Los recursos educativos abiertos se han erigido como uno de los pilares fundamentales de la educación abierta. Una de las principales barreras que está obstaculizando su uso y adopción es la carencia de mecanismos de control de calidad efectivos y sostenibles en los repositorios. Estrategias de evaluación como la revisión por pares no han resultado lo su®cientemente escalables para afrontar el ritmo de creación de materiales abiertos por parte de la comunidad. El presente estudio muestra una nueva estrategia basada en analíticas de aprendizaje para estimar la calidad de los objetos de aprendizaje en base a las interacciones que los estudiantes tienen con ellos en entornos abiertos. Se analizaron 146.291 sesiones de interacción de estudiantes con 256 objetos de aprendizaje distribuidos a través de un repositorio abierto. Un total de 11 interacciones estudiante-objeto de aprendizaje fueron consi- deradas en el estudio. La calidad de los recursos fue medida empleando el instrumento estándar de evaluación LORI (Learning Object Review Instru- ment. Para estudiar las relaciones entre las interacciones de los estudiantes con los objetos de aprendizaje y la calidad de los mismos y para construir una métrica de predicción se utilizaron análisis de regresión lineal. Los resulta- dos muestran que existe relación entre las interacciones y la calidad, y que es posible estimar con un error moderado la calidad de los objetos de apren- dizaje en base a las interacciones que los estudiantes tienen con ellos. Los resultados obtenidos señalan que la analítica de aprendizaje propuesta puede ser utilizada en repositorios de objetos de aprendizaje abiertos para detectar automáticamente recursos con ̄ictivos o de baja calidad.

  7. COSYMA: Health effects models

    1995-02-01

    As one of the main objectives of the MARIA project (''Methods for Assessing the Radiological Impact of Accidents'') initiated by the Commission of the European Communities the program package COSYMA (''COde SYstem from MARIA'') for assessing the radiological and economic off-site consequences of accidental releases of radioactive material to the atmosphere has been jointly developed by the Kernforschungszentrum Karlsruhe (KfK), FRG, and the National Radiological Protection Board (NRPB), UK. COSYMA includes models and data for assessing a broad spectrum of accident consequences, and they are implemented in independent modules. The subject of this report are those modules, which incorporate models and data for assessing individual and collective risks for deterministic and stochastic health effects. It describes the models implemented, the mathematical algorithms and the required data. Examples are given and explained for the input and output part of the modules. (orig.)

  8. Health effects of radon

    International Nuclear Information System (INIS)

    Easterly, C.

    1994-01-01

    Exposure of people to radon has taken on increased interest during the last decade because of the understanding that buildings can serve to trap radon and its daughters, and thereby build up undesirable concentrations of these radioactive elements. Numerous studies of underground miners (often uranium miners) have shown an increased risk of lung cancer in comparison with nonexposed populations. Laboratory animals exposed to radon daughters also develop lung cancer. The abundant epidemiological and experimental data have established the carcinogenicity of radon progeny. Those observations are of considerable importance, because uranium, from which radon and its progeny arise, is ubiquitous in the earth's crust, including coal mines. Risk estimates of the health effects of long-term exposures at relatively low levels require continued development, especially to address the potential health effects of radon and radon daughters in homes and occupational settings where the exposure levels are less than levels in underground uranium and other metal mines that have been the subject of epidemiological studies. Two approaches can be used to characterize the lung-cancer risks associated with radon-daughter exposure: mathematical representations of the respiratory tract that model radiation doses to target cells and epidemiological investigation of exposed populations, mainly underground uranium miners. The mathematically-based dosimetric approach provides an estimate of lung cancer risk related to radon-daughter exposure based specifically on modeling of the dose to target cells. The various dosimetric models all require assumptions, some of which are not subject to direct verification, as to breathing rates; the deposition of radon daughters in the respiratory tract; and the type, nature, and location of the target cells for cancer induction. The most recent large committee effort drawn together to evaluate this issue was sponsored by the National Research Council

    This paper primarily discusses health effects that have resulted from exposures received as a result of above-ground nuclear tests, with emphasis on thyroid disease from exposure to 131I and leukemia and solid cancers from low dose rate external and internal exposure. Results of epidemiological studies of fallout exposures in the Marshall Islands and from the Nevada Test Site are summarized, and studies of persons with exposures similar to those from fallout are briefly reviewed (including patients exposed to 131I for medical reasons and workers exposed externally at low doses and low dose rates). Promising new studies of populations exposed in countries of the former Soviet Union are also discussed and include persons living near the Semipalatinsk Test Site in Kazakhstan, persons exposed as a result of the Chernobyl accident, and persons exposed as a result of operations of the Mayak Nuclear Plant in the Russian Federation. Very preliminary estimates of cancer risks from fallout doses received by the United States population are presented.

  17. Ozone health effects

    International Nuclear Information System (INIS)

    Easterly, C.

    1994-01-01

    Ozone is a principal component of photochemical air pollution endogenous to numerous metropolitan areas. It is primarily formed by the oxidation of NOx in the presence of sunlight and reactive organic compounds. Ozone is a highly active oxidizing agent capable of causing injury to the lung. Lung injury may take the form of irritant effects on the respiratory tract that impair pulmonary function and result in subjective symptoms of respiratory discomfort. These symptoms include, but are not limited to, cough and shortness of breath, and they can limit exercise performance. The effects of ozone observed in humans have been primarily limited to alterations in respiratory function, and a range of respiratory physiological parameters have been measured as a function of ozone exposure in adults and children. These affects have been observed under widely varying (clinical experimental and environmental settings) conditions

    Faroon, O; Roney, N; Taylor, J; Ashizawa, A; Lumpkin, M H; Plewak, D J

    2008-08-01

    Acrolein is a chemical used as an intermediate reactive aldehyde in chemical industry. It is used for synthesis of many organic substances, methionine production, and methyl chloride refrigerant. The general population is exposed to acrolein via smoking, second-hand smoke, exposure to wood and plastic smoke. Firefighters and population living or working in areas with heavy automotive traffic may expose to higher level of acrolein via inhalation of smoke or automotive exhaust. Degradation of acrolein in all environmental media occurs rapidly, therefore, environmental accumulation is not expected. Acrolein degrade in 6A days when applied to surface water, and it has not been found as a contaminant in municipal drinking water. Acrolein vapor may cause eye, nasal and respiratory tract irritations in low level exposure. A decrease in breathing rate was reported by volunteers acutely exposed to 0.3A ppm of acrolein. At similar level, mild nasal epithelial dysplasia, necrosis, and focal basal cell metaplasia have been observed in rats. The acrolein effects on gastrointestinal mucosa in the animals include epithelial hyperplasia, ulceration, and hemorrhage. The severity of the effects is dose dependent. Acrolein induces the respiratory, ocular, and gastrointestinal irritations by inducing the release of peptides in nerve terminals innervating these systems. Levels of acrolein between 22 and 249 ppm for 10 min induced a dose-related decrease in substance P (a short-chain polypeptide that functions as a neurotransmitter or neuromodulator).

    2015-01-01

    Full Text Available Background Noise pollution is of particular importance due to the physical and psychological effects on humans. Noise is a stressor that affects the autonomic nervous system and the endocrine system. Noise is also a threat to marine and terrestrial ecosystems. Health risks from noise are correlated with road traffic. In other words, noise health effects are the health consequences of elevated sound levels. Objectives This study aims to determine the effect of noise pollution (near roadways on health issues in Ahvaz, Iran. Materials and Methods In this cross-sectional study, equivalent sound pressure level were measured by sound level meters TES-1353 in 75 locations around 4 roadways, which had a high load of traffic in Ahvaz City during day time. During the study, 820 measurements were recorded at measuring stations, for 7 days per week with 1-hour interval between each measurement. Statistical analysis was carried out by SPSS software. Results According to the research findings, the equivalent sound pressure levels in all stations were 76.28 ± 3.12 dB (Mean ± SD. According to sound measurements and the survey questionnaire, noise pollution is higher than EPA (US Environmental Protection Agency and Iran standard level. Based on result of this study the worst noise health effects were the nervousness and sleep quality during 2012. Conclusions According to the results of this study, with increasing load of traffic, there is an increasing need for proper consideration plans to control noise pollution and prevent its effects.

    Objective With the rapid increase in use of electronic nicotine delivery systems (ENDS), such as electronic cigarettes (e-cigarettes), users and non-users are exposed to the aerosol and product constituents. This is a review of published data on the human health effects of exposure to e-cigarettes and their components. Methods Literature searches were conducted through September 2013 using multiple electronic databases. Results Forty-four articles are included in this analysis. E-cigarette aerosols may contain propylene glycol, glycerol, flavourings, other chemicals and, usually, nicotine. Aerosolised propylene glycol and glycerol produce mouth and throat irritation and dry cough. No data on the effects of flavouring inhalation were identified. Data on short-term health effects are limited and there are no adequate data on long-term effects. Aerosol exposure may be associated with respiratory function impairment, and serum cotinine levels are similar to those in traditional cigarette smokers. The high nicotine concentrations of some products increase exposure risks for non-users, particularly children. The dangers of secondhand and thirdhand aerosol exposure have not been thoroughly evaluated. Conclusions Scientific evidence regarding the human health effects of e-cigarettes is limited. While e-cigarette aerosol may contain fewer toxicants than cigarette smoke, studies evaluating whether e-cigarettes are less harmful than cigarettes are inconclusive. Some evidence suggests that e-cigarette use may facilitate smoking cessation, but definitive data are lacking. No e-cigarette has been approved by FDA as a cessation aid. Environmental concerns and issues regarding non-user exposure exist. The health impact of e-cigarettes, for users and the public, cannot be determined with currently available data. PMID:24732161

Aerosol exposure may be associated with respiratory function impairment, and serum cotinine levels are similar to those in traditional cigarette smokers. The high nicotine concentrations of some products increase exposure risks for non-users, particularly children. The dangers of secondhand and thirdhand aerosol exposure have not been thoroughly evaluated. Scientific evidence regarding the human health effects of e-cigarettes is limited. While e-cigarette aerosol may contain fewer toxicants than cigarette smoke, studies evaluating whether e-cigarettes are less harmful than cigarettes are inconclusive. Some evidence suggests that e-cigarette use may facilitate smoking cessation, but definitive data are lacking. No e-cigarette has been approved by FDA as a cessation aid. Environmental concerns and issues regarding non-user exposure exist. The health impact of e-cigarettes, for users and the public, cannot be determined with currently available data.

  8. Revised nonstochastic health effects models

    International Nuclear Information System (INIS)

    Yaniv, S.S.; Scott, B.R.

    1991-01-01

    In 1989, the U.S. Nuclear Regulatory Commission (NRC) published a revision of the 1985 report, Health Effects Models for Nuclear Power Plant Accident Consequence Analysis, NUREG/CR-4214, that included models for early occurring and continuing nonstochastic effects, cancers and thyroid nodules, and genetic effects. This paper discusses specific models for lethality from early occurring and continuing effects. For brevity, hematopoietic-syndrome lethality is called hematopoietic death; pulmonary-syndrome lethality is called pulmonary death; and gastrointestinal syndrome lethality is called gastrointestinal death. Two-parameter Weibull risk functions are recommended for estimating the risk of hematopoietic, pulmonary, or gastrointestinal death. The risks are obtained indirectly by using hazard functions; as a result, this type of approach has been called hazard-function modeling and the models generated are called hazard-function models. In the 1989 NUREG/CR-4214 report, changes were made in the parameter values for a number of effects, and the models used to estimate hematopoietic and pulmonary deaths were substantially revised. Upper and lower estimates of model parameters are provided for all early health effects models. In this paper, we discuss the 1989 models for hematopoietic and pulmonary deaths, highlighting the differences between the 1989 and 1985 models. In addition, we give the reasons for which the 1985 models were modified

    Science.gov (United States)

    Health and Environmental Effects Documents (HEEDS) are prepared for the Office of Solid Waste and Emergency Response (OSWER). This document series is intended to support listings under the Resource Conservation and Recovery Act (RCRA) as well as to provide health-related limits and goals for emergency and remedial actions under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). Both published literature and information obtained from Agency Program Office files are evaluated as they pertain to potential human health, aquatic life and environmental effects of hazardous waste constituents. Several quantitative estimates are presented provided sufficient data are available. For systemic toxicants, these include Reference Doses (RfDs) for chronic and subchronic exposures for both the inhalation and oral exposures. In the case of suspected carcinogens, RfDs may not be estimated. Instead, a carcinogenic potency factor, or q1*, is provided. These potency estimates are derived for both oral and inhalation exposures where possible. In addition, unit risk estimates for air and drinking water are presented based on inhalation and oral data, respectively. Reportable quantities (RQs) based on both chronic toxicity and carcinogenicity are derived. The RQ is used to determine the quantity of a hazardous substance for which notification is required in the event of a release as specified under CERCLA.

    Full Text Available Accumulating data clearly claimed that Punica granatum L. (pomegranate has several health benefits. Pomegranates can help prevent or treat various disease risk factors including high blood pressure, high cholesterol, oxidative stress, hyperglycemia, and inflammatory activities. It is demonstrated that certain components of pomegranate such as polyphenols have potential antioxidant, anti-inflammatory, and anticarcinogenic effects. The antioxidant potential of pomegranate juice is more than that of red wine and green tea, which is induced through ellagitannins and hydrosable tannins. Pomegranate juice can reduce macrophage oxidative stress, free radicals, and lipid peroxidation. Moreover, pomegranate fruit extract prevents cell growth and induces apoptosis, which can lead to its anticarcinogenic effects. In addition, promoter inhibition of some inflammatory markers and their production are blocked via ellagitannins. In this article, we highlight different studies on the therapeutic effects of pomegranate and their suggested mechanisms of actions.

    1993-01-01

    Biomass fuels such as coal, wood, crop residues, kerosene oil and dung-cakes meet the energy needs in the household sector in India and other developing countries. Crop residues and dung-cakes are largely used in rural areas, whereas wood forms the major source of fuel in urban as well as rural areas. Combustion of these fuels produces various kinds of poisonous gases such as CO, smoke, nitrogen dioxide, polycyclic aromatic hydrocarbons and respirable particulates. These gases are released in the domestic environment and they pollute the indoor air. The women and children are the one who suffer most from this air pollution. This results into a variety of health problems principally pertaining to respiratory system among the women and children. Studies on this aspect are reviewed. They point towards the positive relationship between biomass smoke and various health effects, particularly respiratory diseases. Need for research on the ways to prevent pollution due to biomass and resultant health hazards is emphasised. (M.G.B.). 25 refs., 2 tabs

    Full text : A summary of the nature of radiactive contamination would be incomplete without some mention of the human health effects relatied to radioactivity and radioactive materials. Several excellent reviews at the variety of levels of detail have been written and should be consulted by the reader. Internal exposures of alpha and beta particles are important for ingested and inhaled radionuclides. Dosimetry models are used to estimate the dose from internally deposited radioactive particles. As mentioned above weighting parameters that take into account the radiation type, the biological half-life and the tissue or organ at risk are used to convert the physically absorbed dose in units of gray (or red) to the biologically significant committed equivalent dose and effective dose, measured in units of Sv (or rem). There is considerable controversy over the shape of the dose-response curve at the chronic low dose levels important for enviromental contamination. Proposed models include linear models, non-linear models and threshold models. Because risks at low dose must be extrapolated from available date at high doses, the shape of the dose-response curve has important implications for the environmental regulations used to protect the general public. The health effect of radiation damage depends on a combination of events of on the cellular, tissue and systemic levels. These lead to mutations and cellular of the irradiated parent cell. The dose level at which significant damage occurs depends on the cell type. Cells that reproduce rapidily, such as those found in bone marrow or the gastrointestinal tract, will be more sensitive to radiation than those that are longer lived, such as striated muscle or nerve cells. The effects of high radiation doses on an organ depends on the various cell types it contains

    This report introduces general information about diesel particles and their health effects. The purpose of this report is to introduce particulate matter pollution and present some recent studies made regarding the health effects of particulate matter. The aim is not to go very deeply into the science, but instead to keep the text understandable for the average layman. Particulate matter is a complex mixture of extremely small particles and liquid droplets. These small particles are made up of a number of components that include for example acids, such as nitrates and sulphates, as well as organic chemicals, metals and dust particles from the soil. Particulate matter comes from several sources, such as transportation emissions, industrial emissions, forest fires, cigarette smoke, volcanic ash and climate variations. Particles are divided into coarse particles with diameters less than 10 ..m, fine particles with diameters smaller than 2.5 ..m and ultra-fine particles with diameters less than 0.1 ..m. The particulate matter in diesel exhaust gas is a highly complex mixture of organic, inorganic, solid, volatile and partly volatile compounds. Many of these particles do not form until they reach the air. Many carcinogenic compounds have been found in diesel exhaust gas and it is considered carcinogenic to humans. Particulate matter can cause several health effects, such as premature death in persons with heart or lung disease, cancer, nonfatal heart attacks, irregular heartbeat, aggravated asthma, decreased lung function and an increase in respiratory symptoms, such as irritation of the airways, coughing or difficulty breathing. It is estimated that in Finland about 1300 people die prematurely due to particles and the economic loss in the EU due to the health effects of particles can be calculated in the billions. Ultra-fine particles are considered to be the most harmful to human health. Ultrafine particles usually make the most of their quantity and surface area

  17. Health effects and medical surveillance

    International Nuclear Information System (INIS)

    2004-01-01

    This Practical Radiation Technical Manual is one of a series which has been designed to provide guidance on radiological protection for employers, Radiation Protection Officers, managers and other technically competent persons who have a responsibility to ensure the safety of employees working with ionizing radiation. The Manual may be used with the appropriate IAEA Practical Radiation Safety Manuals to provide adequate training, instruction or information on health effects and medical surveillance for all employees engaged in work with ionizing radiation. Sources of ionizing radiations have a large number of applications in the workplace. Usually, even where the work is performed safely, the employees involved inevitably receive small, regular exposures to radiation that are not harmful. Some applications involve sources that could deliver more significant radiation doses, particularly when poor methods are practised or an accident occurs. The radiations cannot be seen, felt or sensed by the human body in any way and excessive exposures may cause detriment to the health of a worker in a way that is not immediately apparent. When the symptoms occur, weeks or possibly years later, an untrained worker or inexperienced medical staff probably cannot recognize the effects to be due to the radiation exposure. This Manual explains how ionizing radiations can interact with and affect human tissues, the various factors that influence the outcome and the detrimental effects that may result. The medical surveillance that is appropriate for those working with radiation sources, depending on the degree of hazard of the work, is described. The Manual will be of most benefit if it forms part of more comprehensive training or is supplemented by the advice of a medically qualified expert. Where medical surveillance is appropriate for radiation employees, the services of a qualified doctor, occupational physician or other trained medical staff will be required

  18. Health effects of indoor odorants.

    Cone, J E; Shusterman, D

    1991-11-01

    People assess the quality of the air indoors primarily on the basis of its odors and on their perception of associated health risk. The major current contributors to indoor odorants are human occupant odors (body odor), environmental tobacco smoke, volatile building materials, bio-odorants (particularly mold and animal-derived materials), air fresheners, deodorants, and perfumes. These are most often present as complex mixtures, making measurement of the total odorant problem difficult. There is no current method of measuring human body odor, other than by human panel studies of expert judges of air quality. Human body odors have been quantitated in terms of the "olf" which is the amount of air pollution produced by the average person. Another quantitative unit of odorants is the "decipol," which is the perceived level of pollution produced by the average human ventilated by 10 L/sec of unpolluted air or its equivalent level of dissatisfaction from nonhuman air pollutants. The standard regulatory approach, focusing on individual constituents or chemicals, is not likely to be successful in adequately controlling odorants in indoor air. Besides the current approach of setting minimum ventilation standards to prevent health effects due to indoor air pollution, a standard based on the olf or decipol unit might be more efficacious as well as simpler to measure.

    2016-03-01

    Occupational exposures in the agricultural industry are associated with numerous lung diseases, including chronic obstructive pulmonary disease, asthma, hypersensitivity pneumonitis, lung cancer, and interstitial lung diseases. Efforts are ongoing to ascertain contributing factors to these negative respiratory outcomes and improve monitoring of environmental factors leading to disease. In this review, recently published studies investigating the deleterious effects of occupational exposures in the agricultural industry are discussed. Occupational exposures to numerous agricultural environment aerosols, including pesticides, fungi, and bacteria are associated with impaired respiratory function and disease. Increases in certain farming practices, including mushroom and greenhouse farming, present new occupational exposure concerns. Improved detection methods may provide opportunities to better monitor safe exposure levels to known lung irritants. In the agricultural industry, occupational exposures to organic and inorganic aerosols lead to increased risk for lung disease among workers. Increased awareness of respiratory risks and improved monitoring of agricultural environments are necessary to limit pulmonary health risks to exposed populations.

    2012-01-01

    Full Text Available Health promotion is very relevant today. There is a global acceptance that health and social wellbeing are determined by many factors outside the health system which include socioeconomic conditions, patterns of consumption associated with food and communication, demographic patterns, learning environments, family patterns, the cultural and social fabric of societies; sociopolitical and economic changes, including commercialization and trade and global environmental change. In such a situation, health issues can be effectively addressed by adopting a holistic approach by empowering individuals and communities to take action for their health, fostering leadership for public health, promoting intersectoral action to build healthy public policies in all sectors and creating sustainable health systems. Although, not a new concept, health promotion received an impetus following Alma Ata declaration. Recently it has evolved through a series of international conferences, with the first conference in Canada producing the famous Ottawa charter. Efforts at promoting health encompassing actions at individual and community levels, health system strengthening and multi sectoral partnership can be directed at specific health conditions. It should also include settings-based approach to promote health in specific settings such as schools, hospitals, workplaces, residential areas etc. Health promotion needs to be built into all the policies and if utilized efficiently will lead to positive health outcomes.

  5. Health effects of ionizing radiation

    International Nuclear Information System (INIS)

    Pathak, B.

    1989-12-01

    Ionizing radiation is energy that travels through space as electromagnetic waves or a stream of fast moving particles. In the workplace, the sources of ionizing radiation are radioactive substances, nuclear power plants, x-ray machines and nuclear devices used in medicine, research and industry. Commonly encountered types of radiation are alpha particles, beta particles and gamma rays. Alpha particles have very little penetrating power and pose a risk only when the radioactive substance is deposited inside the body. Beta particles are more penetrating than alpha particles and can penetrate the outer body tissues causing damage to the skin and the eyes. Gamma rays are highly penetrating and can cause radiation damage to the whole body. The probability of radiation-induced disease depends on the accumulated amount of radiation dose. The main health effects of ionizing radiation are cancers in exposed persons and genetic disorders in the children, grandchildren and subsequent generations of the exposed parents. The fetus is highly sensitive to radiation-induced abnormalities. At high doses, radiation can cause cataracts in the eyes. There is no firm evidence that ionizing radiation causes premature aging. Radiation-induced sterility is highly unlikely for occupational doses. The data on the combined effect of ionizing radiation and other cancer-causing physical and chemical agents are inconclusive

    Despite modern day ventilation, underground miners are exposed to diesel particulate matter (DPM) composed of elemental carbon, organic carbon, sulphates, metals and ashes. Diesel exhaust contains over 40 air contaminants that have been recognized as toxic, carcinogenic or reproductive and developmental hazards. Nearly all components of diesel exhaust interact with the human body at the bloodstream or tissue level. This presentation discussed the following 4 potential levels of threat posed by the physical and chemical nature of diesel exhaust: (1) cancer of the lungs and bladder, (2) toxins that affect the nervous, endocrine, reproductive and immune system as well as the liver and kidneys, (3) fine particulate matter that can cause premature death and an increase in respiratory illness, and (4) nitrogen oxides that contribute to increased ozone and smog. Non-cancer health effects from short-term exposure include acute irritation and respiratory symptoms. This presentation also referred to cancer risk assessments of diesel exhaust by national, state, and world health organizations. Particulate exposure standards for Canada, Quebec, Ontario and the United States were listed along with the percentage of DPM samples in excess of various exposure limits in 2008 according to Canadian underground mine data. DPM concentration levels in mines are in the range that environmental agencies would consider high for general population exposure. Solutions for underground mines include pollution control at the source; use of modern engines with certification for underground mining; emissions based maintenance; exhaust treatment; use of clean or alternative fuels such as hydrogen; regular sampling and monitoring; ventilation; training and technology transfer; and regulations. tabs., figs.

    2000-01-01

    Human and animal studies have shown an increased incidence of cancer and malformation due to radioactive materials and external radiation. The biological effects of radiation on tissues are the occurrence of morphological and functional changes in the body. The critical parts of the body are those tissues or organs which when irradiated, are likely to influence the health of the individual or its offspring. The probability of these changes depends on the radiation dose. There are two main types of damage due to radiation dose. Radiation Sickness with well-defined symptoms like cancer and inherited disorders which can appear after several years. A second type of damage, namely Acute Radiation Sickness results after exposure of the whole or parts of the body to high doses of radiation greater than 1 Gy. There are safety standards for the amount of dose equivalent that is taken as acceptable. The International Commission on Radiological Protection (ICRP) has given norms in which natural and medical causes were not included. These are given as recommended values (1966) and proposed values (2000), both in mSv/yr: population at large: 1.7 and 0.4; members of the public: 5 and 2; and radiologic workers: 50 and 20, respectively. Taking into account the increased number of reactor accidents, the question is how safe is our safety standards? Even when one is able to connect a quantitative risk with a radiation dose, there are three fundamental principles which we should obey in dealing with risks from radiation. These are: (1) Avoid any risk. (2) The risk should be related to the possible benefit. (3) Any dose below the politically agreed limits is acceptable

    Although traditional meditation has been found to be effective in improving physical and mental health of subjects, there was a paucity of research of the effect of active or dynamic meditation on these variables. Therefore, the present study was aimed at studying the effect of dynamic meditation on mental health of the subjects. Total sample of the present study comprised 60 subjects, 30 each in experimental and control group. Subjects in experimental group were given 21-day training in dynamic meditation. Mental health of the experimental and control group subjects was measured in pre- and post-condition with the help of Mental Health Inventory developed by Jagadish and Srivastava (Mental Health inventory, Manovaigyanik Parikshan Sansthan, Varanasi, 1983). Obtained data were analyzed with the help of ANCOVA. In post-condition, experimental group scored better than control group on integration of personality, autonomy and environmental mastery. Effect sizes of dynamic meditation on these dimensions of mental health were large. However, experimental group and control group did not differ significantly on positive self-evaluation, perception of reality and group-oriented attitude dimensions of mental health in post-condition. Overall, dynamic meditation training was effective in improving mental health of the subjects.

    Our accumulated technology has added roughly 50 years to the average life span of a human being in North America. Most of this increase in life span has occurred within the last 100 years. Cheap and safe supplies of energy are required for the industrial prosperity that has made this possible. The best estimates available all indicate that nuclear power and natural gas are the safest forms of contemporary energy production. The largest potential radiation hazard to which we are currently exposed appears to derive from our houses; increased attention by public health authorities to the control of this particular hazard may be warranted.

  8. Health effects of vegan diets.

    Science.gov (United States)

    2009-05-01

    Recently, vegetarian diets have experienced an increase in popularity. A vegetarian diet is associated with many health benefits because of its higher content of fiber, folic acid, vitamins C and E, potassium, magnesium, and many phytochemicals and a fat content that is more unsaturated. Compared with other vegetarian diets, vegan diets tend to contain less saturated fat and cholesterol and more dietary fiber. Vegans tend to be thinner, have lower serum cholesterol, and lower blood pressure, reducing their risk of heart disease. However, eliminating all animal products from the diet increases the risk of certain nutritional deficiencies. Micronutrients of special concern for the vegan include vitamins B-12 and D, calcium, and long-chain n-3 (omega-3) fatty acids. Unless vegans regularly consume foods that are fortified with these nutrients, appropriate supplements should be consumed. In some cases, iron and zinc status of vegans may also be of concern because of the limited bioavailability of these minerals.

    As input to design considerations precluding worker radiological exposure that could lead to an acute health effect from a postulated accident condition, an assessment of the short term health effects was performed. To assure that the impact of the accident scenario on the individual is appropriately considered, both external and internal exposures are included in the evaluation. The focus of this evaluation was to develop a quantitative basis from which to consider the level of exposure postulated in an accident that could lead to a defined physiological impact for short term health effects. This paper does not assess latent health effects of radiological exposure associated with normal operations or emergency response guidelines as these are clearly articulated in existing regulations and ICRP documents. The intent of this paper is to facilitate a dialogue on the appropriate meaning of currently undefined terms such as ''significant'' exposure and ''high-hazard material'' in DSA development

  16. Industrial wind turbines and adverse health effects.

    Jeffery, Roy D; Krogh, Carmen M E; Horner, Brett

    2014-01-01

    Some people living in the environs of industrial wind turbines (IWTs) report experiencing adverse health and socioeconomic effects. This review considers the hypothesis that annoyance from audible IWTs is the cause of these adverse health effects. We searched PubMed and Google Scholar for articles published since 2000 that included the terms "wind turbine health," "wind turbine infrasound," "wind turbine annoyance," "noise annoyance" or "low frequency noise" in the title or abstract. Industrial wind turbines produce sound that is perceived to be more annoying than other sources of sound. Reported effects from exposure to IWTs are consistent with well-known stress effects from persistent unwanted sound. If placed too close to residents, IWTs can negatively affect the physical, mental and social well-being of people. There is sufficient evidence to support the conclusion that noise from audible IWTs is a potential cause of health effects. Inaudible low-frequency noise and infrasound from IWTs cannot be ruled out as plausible causes of health effects.

    Housing is a central component of productive, healthy, and meaningful lives, and a principle social determinant of health and well-being. Surprisingly, though, evidence on the ways that housing influences health in Australia is poorly developed. This stems largely from the fact that the majority of the population are accommodated in good quality housing. The dominance of a "good housing paradigm" means that households living in poor quality and unhealthy housing are doubly disadvantaged-by the quality of their housing and because policy makers in Australia do not acknowledge the health effects of housing. In this article, we examine the relationship between health outcomes and quality of housing. We base our analysis on data from the Household Income and Labour Dynamics in Australia (HILDA) survey, a panel dataset that is representative across Australia. We find a sizeable, policy-important, and to date under-acknowledged cohort of Australians whose health is influenced by poor-condition dwellings.

  1. Literature survey: health effects of radiation

    This report was originally written as a chapter of a report entitled 'Air pollution effects of electric power generation, a literature survey', written jointly by the Norwegian Institute for Air Research (NILU) and the Institutt for Atomenergi (IFA). (INIS RN242406). A survey is presented of the health effects of radiation. It has not, however, been the intention of the authors to make a complete list of all the literature relevant to this subject. The NILU/IFA report was meant as a first step towards a method of comparing the health effects of electric power generation by fission, gas and oil. Consequently information relevant to quantification of the health effects on humans has been selected. It is pointed out that quantitative information on the health effects of low radiation and dose rates, as are relevant to routine releases, does not exist for humans. The convention of linear extrapolation from higher doses and dose rates is used worldwide, but it is felt by most that the estimates are conservative. As an example of the use of the current best estimates, a calculation of normal release radiation doses is performed. (Auth.)

    We assessed the impact of unemployment benefit programs on the health of the unemployed. We linked US state law data on maximum allowable unemployment benefit levels between 1985 and 2008 to individual self-rated health for heads of households in the Panel Study of Income Dynamics and implemented state and year fixed-effect models. Unemployment was associated with increased risk of reporting poor health among men in both linear probability (b=0.0794; 95% confidence interval [CI]=0.0623, 0.0965) and logistic models (odds ratio=2.777; 95% CI=2.294, 3.362), but this effect is lower when the generosity of state unemployment benefits is high (b for interaction between unemployment and benefits=-0.124; 95% CI=-0.197, -0.0523). A 63% increase in benefits completely offsets the impact of unemployment on self-reported health. Results suggest that unemployment benefits may significantly alleviate the adverse health effects of unemployment among men.

    Because of its public health, ecological and industrial consequences, the Chernobyl accident has become a myth which serves as the focus of many fears, justified or not. no one can question the seriousness of the event, but after fifteen years there is still no agreement about the effect it has had or will have on public health. For example, the total number of deaths attributed to Chernobyl varies from less than a hundred to several millions and congenital malformations from negligible to cataclysmic. Effects on public health may be calculated from data on contamination, from the dose received and from the risk, all three of which are likely to be very roughly known; or they may be evaluated on the spot, either by epidemiological studies or by examining medical registers.

Finally, methods of evaluating public relations effectiveness at both the program level and the institutional level are explored.

  6. Health Effects of Chronic Arsenic Exposure

    Full Text Available Arsenic is a unique element with distinct physical characteristics and toxicity whose importance in public health is well recognized. The toxicity of arsenic varies across its different forms. While the carcinogenicity of arsenic has been confirmed, the mechanisms behind the diseases occurring after acute or chronic exposure to arsenic are not well understood. Inorganic arsenic has been confirmed as a human carcinogen that can induce skin, lung, and bladder cancer. There are also reports of its significant association to liver, prostate, and bladder cancer. Recent studies have also suggested a relationship with diabetes, neurological effects, cardiac disorders, and reproductive organs, but further studies are required to confirm these associations. The majority of research to date has examined cancer incidence after a high exposure to high concentrations of arsenic. However, numerous studies have reported various health effects caused by chronic exposure to low concentrations of arsenic. An assessment of the health effects to arsenic exposure has never been performed in the South Korean population; thus, objective estimates of exposure levels are needed. Data should be collected on the biological exposure level for the total arsenic concentration, and individual arsenic concentration by species. In South Korea, we believe that biological exposure assessment should be the first step, followed by regular health effect assessments.

    Hazardous chemicals escape to the environment by a number of natural and/or anthropogenic activities and may cause adverse effects on human health and the environment. Increased combustion of fossil fuels in the last century is responsible for the progressive change in the atmospheric composition. Air pollutants, such as carbon monoxide (CO), sulfur dioxide (SO 2 ), nitrogen oxides (NOx), volatile organic compounds (VOCs), ozone (O 3 ), heavy metals, and respirable particulate matter (PM2.5 and PM10), differ in their chemical composition, reaction properties, emission, time of disintegration and ability to diffuse in long or short distances. Air pollution has both acute and chronic effects on human health, affecting a number of different systems and organs. It ranges from minor upper respiratory irritation to chronic respiratory and heart disease, lung cancer, acute respiratory infections in children and chronic bronchitis in adults, aggravating pre-existing heart and lung disease, or asthmatic attacks. In addition, short- and long-term exposures have also been linked with premature mortality and reduced life expectancy. These effects of air pollutants on human health and their mechanism of action are briefly discussed. - The effect of air pollutants on human health and underlying mechanisms of cellular action are discussed

Frequencies, prevalences, and bivariate/multivariate analysis were conducted separately for men (M) and women (W). We estimated the health problems attributable to racism through the population attributable proportion (PAP). Immigrants perceived more racism than Spaniards in workplace (ORM = 48.1; 95% CI 28.2-82.2), and receiving health care (ORW = 48.3; 95% CI 24.7-94.4). Racism and other forms of discrimination were associated with poor mental health (ORM = 5.6; 95% CI 3.9-8.2; ORW = 7.3; 95% CI 4.1-13.0) and injury (ORW = 30.6; 95% CI 13.6-68.7). It is attributed to perceived racism the 80.1% of consumption of psychotropics (M), and to racism with other forms of discrimination the 52.3% of cases of injury (W).

    The results of the latest studies on the effects of urban noise on mental health are presented in this paper. Numerous psychiatric symptoms have been frequently noticed in the population of the settlements with a high level of urban noise: fatigue, headaches, tension, anxiety, irritability, bad concentration, insomnia, whith a consequently high consumption of psychotropic medicines. Higher admission rates in psychiatric hospitals have been noticed from noisy areas in comparison with low noise regions. By use of diagnostic psychiatric interviews it has been shown as well, that in sensitive categories of population positive correlation can be expected between the number of persons with mental disorder and the level of environmental noise. Noise annoyance and sleep disturbance, namely shortening or absence of the sleep phase 4 and REM, are the basic negative psychological effects of noise, with an adverse effect on mental health in general.

    Few population-based studies have analyzed the link between poverty and infant morbidity. In this study, we wanted to determine whether inadequate income itself has an impact on infant health. We interviewed 2223 mothers of 5-month-old children participating in the 1998 phase of the Quebec Longitudinal Study of Child Development to determine their infant's health and the sociodemographic characteristics of the household (including household income, breast-feeding and the smoking habits of the mother). Data on the health of the infants at birth were taken from medical records. We examined the effects of household income using Statistics Canada definitions of sufficient (above the low-income threshold), moderately inadequate (between 60% and 99% of the low-income threshold) and inadequate (below 60% of the low-income threshold) income on the mother's assessment of her child's overall health, her report of her infant's chronic health problems and her report of the number of times, if any, her child had been admitted to hospital since birth. In the analysis, we controlled for factors known to affect infant health: infant characteristics and neonatal health problems, the mother's level of education, the presence or absence of a partner, the duration of breast-feeding and the mother's smoking status. Compared with infants in households with sufficient incomes, those in households with lower incomes were more likely to be judged by their mothers to be in less than excellent health (moderately inadequate incomes: adjusted odds ratio [OR] 1.5, 95% confidence interval [CI] 1.1-2.1; very inadequate incomes: adjusted OR 1.8, 95% CI 1.3-2.6). Infants in households with moderately inadequate incomes were more likely to have been admitted to hospital (adjusted OR 1.8, 95% CI 1.2-2.6) than those in households with sufficient incomes, but the same was not true of infants in households with very inadequate incomes (adjusted OR 0.7, 95% CI 0.4-1.2).

This literature review of the range of organisational, team and individual benefits of teamwork complements an earlier article which summarised the antecedent conditions for (input) and team processes (throughput) of effective teams. This article summarises the evidence for a range of outcome measures of effective teams. Organisational benefits of teamwork include reduced hospitalisation time and costs, reduced unanticipated admissions, better accessibility for patients, and improved coordination of care. Team benefits include efficient use of health care services, enhanced communication and professional diversity. Patients report benefits of enhanced satisfaction, acceptance of treatment and improved health outcomes. Finally, team members report enhanced job satisfaction, greater role clarity and enhanced well-being. Due to the inherent complexity of teamwork, a constituency model of team evaluation is supported where key stakeholders identify and measure the intended benefits of a team.

    The purpose of this work is to analyse the effects on informal caregiver's health and lifestyle when living with a dependent person at home. A comparison will be made between this situation and other situations involving commitment of time and energy, taking into account gender and age differences in each stage of the life cycle. Cross-sectional study analysing secondary data. The method used for collecting information is the computer assisted personal interview carried out in selected homes by the Ministry of Health, Social Services and Equality. The study included 19,351 participants aged over 25 years who completed the 2011-2012 Spanish National Health Survey. This research is based on demographic information obtained from a Spanish National Health Survey (2011/12). Using an empirical framework, the Logit model was select and the data reported as odds ratio. The estimations were repeated independently by sub-groups of age and gender. The study showed that the health of people who share their lives with a dependent person is worse than those who do not have any dependent person at home (they are 5 times at higher risk of developing health problems). The study found that being a woman, advance age, low educational level and does not work, also has an influence. Being a caregiver reduces the likelihood of maintaining a healthy lifestyle through physical exercise, relaxation, or eating a balanced diet. Living with a dependent person reduces the likelihood of maintaining healthy lifestyles and worsens the state of health of family members. Significant differences in gender and age were found.

    This study aimed to examine whether social capital (bonding and bridging social capital) attenuate the effect of low functional health literacy on health information resources, efficacy, and behaviors. In-person interviews were conducted with 1,000 residents in Seoul, Korea, in 2011. The authors found that respondents' functional health literacy had positive effects on the scope of health information sources and health information self-efficacy but not health information-seeking intention. Respondents' social capital had positive effects on the scope of health information sources, health information efficacy, and health information-seeking intention. The authors found (a) a significant moderation effect of bridging social capital on the relation between health literacy and health information self-efficacy and (b) a moderation effect of bonding social capital on the relation between health literacy and health information-seeking intention.

  17. HELLE: Health Effects of Low Level Exposures

    1998-01-01

    The Health Council is closely involved in establishing the scientific foundation of exposure limits for substances and radiation in order to protect public health. Through the years, the Council has contributed to the formulation of principles and procedures, both for carcinogenic and for noncarcinogenic agents. As a rule, the discussion with regard to the derivation of health-based recommended exposure limits centers around the appropriateness of extrapolation methods (What can be inferred from data on high exposure levels and on experimental animals?). Generally speaking, there is a lack of direct information on the health effects of low levels of exposure. Effects at these levels cannot usually be detected by means of traditional animal experiments or epidemiological research. The capacity of these analytical instruments to distinguish between ''signal'' and ''noise'' is inadequate in most cases. Annex B of this report contains a brief outline of the difficulties and the established methods for tackling this problem. In spite of this, the hope exists that the posited weak signals, if they are indeed present, can be detected by other means. The search will have to take place on a deeper level. In other words, effort must be made to discover what occurs at underlying levels of biological organization when organisms are exposed to low doses of radiation or substances. Molecular and cell biology provide various methods and techniques which give an insight into the processes within the cell. This results in an increase in the knowledge about the molecular and cellular effects of exposure to agents, or stated differently, the working mechanisms which form the basis of the health effects. Last year, the Health Council considered that the time was ripe to take stock of the state of knowledge in this field. To this end, an international working conference was held from 19 to 21 October 1997, entitled ''Health Effects of Low Level Exposures: Scientific Developments and

    This article provides an overview of traditional and contemporary management theories. Concerns, characteristics, and skills of effective managers are also presented. Further, a self-assessment (survey) of 7 highly effective health care managers in a South Georgia community was conducted to determine their ratings on 6 management indices. The assessment or Scale of Transformational Leadership uses a Likert-type scale to allow for the evaluation of managers. The scale contains 6 management elements for assessment: attention, meaning, trust, self, vision, and feeling. Individual ratings and group summary skills rating are presented. Findings revealed the order of managerial importance of the elements as follows (from highest to lowest): Management of Trust, Management of Attention, Management of Self, Management of Feeling, Management of Meaning, and Management of Risk. As a second tier, the final ratings are corroborated by health care management interns.

  19. Redistributive effects of Swedish health care finance.

    1998-01-01

    This paper investigates the redistributive effects of the Swedish health care financing system in 1980 and 1990 for four different financial sources: county council taxes, payroll taxes, direct payments and state grants. The redistributive effects are decomposed into vertical, horizontal and 'reranking' segments for each of the four financial sources. The data used are based on probability samples of the Swedish population, from the Level of Living Survey (LNU) from 1981 and 1991. The paper concludes that the Swedish health care financing system is weakly progressive, although direct payments are regressive. There is some horizontal inequity and 'reranking', which mainly comes from the county council taxes, since those tax rates vary for each county council. The implication is that, to some extent, people with equal incomes are treated unequally.

  20. Measuring the health effects of gender.

    Phillips, S P

    2008-04-01

    The health effects of gender are mediated via group-level constraints of sex roles and norms, discrimination and marginalisation of individuals, and internalisation of the stresses of role discordance. Although gender is frequently a lens through which data are interpreted there are few composite measures that insert gender as an independent variable into research design. Instead, sex disaggregation of data is often conflated with gender, identifying statistically significant but sometimes clinically insignificant sex differences. To directly assess the impact of gender on wellbeing requires development of group and individual-level derived variables. At the ecological level such a summative variable could be composed of a selection of group-level measures of equality between sexes. This gender index could be used in ecological and individual-level studies of health outcomes. A quantitative indicator of gender role acceptance and of the personal effects of gender inequities could insert the often hidden variable of gender into individual-level clinical research.

    Organizational health culture is a health-oriented core characteristic of the organization that is shared by all members. It is effective in regulating health-related behavior for employees and could therefore influence the effectiveness of health promotion efforts among organizations and employees. This study applied a multilevel analysis to verify the effects of organizational health culture on the organizational and individual effectiveness of health promotion. At the organizational level, we investigated the effect of organizational health culture on the organizational effectiveness of health promotion. At the individual level, we adopted a cross-level analysis to determine if organizational health culture affects employee effectiveness through the mediating effect of employee health behavior. The study setting consisted of the workplaces of various enterprises. We selected 54 enterprises in Taiwan and surveyed 20 full-time employees from each organization, for a total sample of 1011 employees. We developed the Organizational Health Culture Scale to measure employee perceptions and aggregated the individual data to formulate organization-level data. Organizational effectiveness of health promotion included four dimensions: planning effectiveness, production, outcome, and quality, which were measured by scale or objective indicators. The Health Promotion Lifestyle Scale was adopted for the measurement of health behavior. Employee effectiveness was measured subjectively in three dimensions: self-evaluated performance, altruism, and happiness. Following the calculation of descriptive statistics, hierarchical linear modeling (HLM) was used to test the multilevel hypotheses. Organizational health culture had a significant effect on the planning effectiveness (β = .356, p production (β = .359, p promotion. In addition, results of cross-level moderating effect analysis by HLM demonstrated that the effects of organizational health culture on three dimensions of

    The presentation gives a brief overview of the types of health effects considered in each of the three subsystems of COSYMA, the way that the corresponding models are implemented and their present default parameter values. The risk of early effects is calculated using hazard functions, as recently recommended by US Nuclear Regulatory Commission and NRPB. The early fatal effects specified in COSYMA comprise those following the irradiation of the bone marrow (hematopoietic syndrome), the lung (pulmonary syndrome), the GI-tract (gastrointestinal syndrome) and skin (skin burns). In addition the mortality of pre-and neonates after exposure in utero is quantified. Of the possible non-fatal effects the only ones included are those which lead to a severe disability of the affected person for the rest of their life or which require medical treatment and/or social care

  3. Effects of air pollution on human health

    1961-01-01

    An appreciable amount of knowledge exists about the effects of community air pollution upon human health. This knowledge comes in part from direct studies of the air pollution health problem and in part from investigations done for other purposes. It is equally apparent that there are many aspects of the subject of the health effects of air pollution on which sound information is lacking. Many years undoubtedly will pass before we have the answers to all the questions involved. Man-made air pollution could be entirely eliminated, but the price that civilization would be required to pay for this would be exorbitant by any standards, whether monetary or otherwise. It is unreasonable to contemplate that we could put a stop to all combustion, the chief source of man-made air pollution. It is logical, however, to consider that the clarification of the air on a qualitatively and quantitatively selective basis is feasible, and in some cases, highly desirable. This can be done, for example, by selectively arresting the contaminants at their source. 404 references.

However, in contrast to most other work places...... of the health consequences of whole body vibrations in land-transportation, such exposure at sea may affect ships’ passengers and crews. While the relation of back disorders to high levels of whole body vibration has been demonstrated among e.g. tractor drivers, there are no reported epidemiological evidence...... for such relation among seafarers except for fishermen, who, however, are also exposed to additional recognised physical risk factors at work. The assessment and reduction of vibrations by naval architects relates to technical implications of this impact for the ships’ construction, but has limited value...

    Cyanobacteria (blue algae) regularly cause recreational waters to become murky and smelly. Skin irritation and mild gastrointestinal disorders have regularly been reported following recreational activities in water suspected of being contaminated with cyanobacteria. The exact cause of these effects on health is not clear. Severe effects are not to be expected from recreational exposure to water contaminated with cyanobacteria. Cyanobacteria can produce hepatotoxins, neurotoxins, cytotoxins and irritants. In Brazil lethal intoxications have occurred due to the occurrence of toxins in drinking water and in dialysis fluid. The Dutch policy is based on the Commissie Integraal Waterbeheer (Commission Integral Water Management) guidelines for recreational waters. It is not clear to what extent the other cyanotoxins occur in the Netherlands. However, several genera ofcyanobacteria capable of producing these other cyanotoxins have been found in the Netherlands. For a good risk assessment in the Netherlands, more information is needed on the effects on health of cyanobacteria. There is also a need for more data on the prevalence of different cyanobacteria and toxins in Dutch recreational waters.

Moreover, studies on this issue in sub-Saharan Africa are scarce. Therefore, this study aims to analyze the effect of health development aid in sub-Saharan Africa. Methods: Using panel data analytic method, as well as infant mortality rate as a proxy for health status, this study examines the effect of health aid on infant mortality rate in sub-Saharan Africa. The panel was constructed from data on 43 countries for the period 1990–2010. Fixed effect, random effect, and first difference generalized method of moments estimator were used for estimation. Results: Health development aid has a statistically significant positive effect. A 1% increase of health development assistance per capita saves the lives of two infants per 1,000 live births (P=0.000 in the region. Conclusion: Contrary to health aid pessimists’ view, this study observes the fact that health development assistance has strong favorable effect in improving health status in sub-Saharan Africa.

    2006-01-01

    Nuclear energy production is necessarily associated with the handling and storage of radioactive elements, which are liable to have deleterious effects on human health, and on environment. These deleterious effects are varied, but they greatly depend on the dose, which has been received, and the exposure type. Therefore, only intense and massive exposures are liable to be clinically detected. They can entail immediate consequences, even lead to the person's death. Thanks to safety measures, which have been implemented to an international scale, this occurs very rarely. Excluding extensive accidental cases, medical irradiation for therapeutic use and conflicts, workers and population in general are exposed to low doses and low dose-rates. Low dose exposures, resulting from either a contamination or an external irradiation are more frequent. In fact, we could say that the whole humanity is concerned by natural exposure, which varies depending on regions, as well as by medical exposure, which varies depending on the medicalisation status of the country.

    This review described carcinogenic and genetic effects of A-bomb radiation. Effects have been investigated on 120,000 exposed people for their life span, 20,000 for health examinations, 3,000 people exposed in the womb and 80,000 second-generations of the exposed people. Epidemiological data revealed the presence of carcinogenic effects: Cancer death amounted to 9% from 1950 to 1990. However, carcinogenic mechanism is unknown yet. Genetic effects have been studied from the points of lesion at birth, sex ratio, chromosome aberration, biochemical test and mortality rate of children of exposed people and, although the effects have been experimentally shown in animals, are not observed in those children. This may be derived from the fact that there are few people who were exposed to such a high dose as used experimentally (0.2 Sv exposure to people within 2.5 km diameter-area from the explosion point vs >3 Sv in animals). Data are presented in Research Foundation home page. (K.H.)

    Currently very popular in the market of tobacco products have gained electronic cigarettes (ang. E-cigarettes). These products are considered to be potentially less harmful in compared to traditional tobacco products. However, current reports indicate that the statements of the producers regarding to the composition of the e- liquids not always are sufficient, and consumers often do not have reliable information on the quality of the product used by them. This paper contain a review of previous reports on the composition of e-cigarettes and their impact on health. Most of the observed health effects was related to symptoms of the respiratory tract, mouth, throat, neurological complications and sensory organs. Particularly hazardous effects of the e-cigarettes were: pneumonia, congestive heart failure, confusion, convulsions, hypotension, aspiration pneumonia, face second-degree burns, blindness, chest pain and rapid heartbeat. In the literature there is no information relating to passive exposure by the aerosols released during e-cigarette smoking. Furthermore, the information regarding to the use of these products in the long term are not also available.

    The health effects of human exposure to cadmium are discussed with emphases on intake, absorption, body burden, and excretion; osteomalacia in Japan; hypertension; and proteinuria, emphysema, osteomalacia, and cancer in workers. Elevated blood pressure has not been observed as a result of excessive exposures to cadmium in Japan or the workplace. Renal tubular dysfunction and consequent proteinuria is generally accepted as the main effect following long-term, low-level exposure to cadmium. Studies of workers show that proteinuria may develop after the first year of exposure or many years after the last exposure. Proteinuria and deterioration of renal function may continue even after cessation of exposure. The immediate health significance of low-level proteinuria is still under debate. However, there is evidence that long-term renal tubular dysfunction may lead to abnormalities of calcium metabolism and osteomalacia. The few autopsy and cross-sectional studies of workers do not permit conclusions to be drawn regarding the relationship between cadmium exposure and emphysema. Retrospective and historical-prospective studies are needed to settle this important question. No conclusive evidence has been published regarding cadmium-induced cancer in humans. However, there is sufficient evidence to regard cadmium as a suspect renal and prostate carcinogen. Because of equivocal results and the absence of dose-response relationships, the studies reviewed should be used with caution in making regulatory decisions and low-dose risk assessments. 62 references.

    In this research, we aimed to evaluate the support for asbestos health consultation in health centers. In this exploratory descriptive study, a self-administered original questionnaire was developed and used. Among all 517 health centers, valid responses were returned from 323 (62.5%) consenting centers. Consultations in the previous year ranged from 0-108 cases, with a facility median of 3.0 cases. Among staff members, 86.4% did not receive training and 35.4% had never used the manual. Workplaces that use asbestos within their jurisdiction were recognized by 39.2% of staff members, and 16.7% of these members always supported consultants psychologically. The staff members were not confident about asbestos health consultation: 71.2% for general questions, 76.2% for questions about asbestos-related diseases, and 76.4% for questions about risk of asbestos-related diseases; 51.4% were not confident about the Asbestos-Related Health Damage Relief System. Health center staff members who were significantly more confident were those who had more staff to work with; dealt with many consultations in the previous year; recognized the workplaces using asbestos within their jurisdiction; often used the manual and often psychologically supported consultants. According to the covariance structure analysis model, the 'use of support systems' consisting of 'the use of manual', 'training attendance' and 'recognition of workplaces that use asbestos' positively affected the frequency of psychological support (peffective in building the confidence of health center staff in relation to asbestos health consultation, although the use of these support systems was low.

    Full Text Available Phthalates are multifunctional chemicals used in a wide variety of consumer products. The aim of this study was to investigate whether levels of urinary phthalate metabolites in urine samples of Austrian mothers and their children were associated with consumer habits and health indicators. Within an Austrian biomonitoring survey, urine samples from 50 mother-child pairs of five communities (two-stage random stratified sampling were analysed. The concentrations of 14 phthalate metabolites were determined, and a questionnaire was administered. Monoethyl phthalate (MEP, mono-n-butyl phthalate (MnBP, mono-isobutyl phthalate (MiBP, monobenzyl phthalate (MBzP, mono-(2-ethylhexyl phthalate (MEHP, mono-(2-ethyl-5-hydroxyhexyl phthalate (5OH-MEHP, mono-(2-ethyl-5-oxohexyl phthalate (5oxo-MEHP, mono-(5-carboxy-2-ethylpentyl phthalate (5cx-MEPP, and 3-carboxy-mono-propyl phthalate (3cx-MPP could be quantified in the majority of samples. Significant correlations were found between the use of hair mousse, hair dye, makeup, chewing gum, polyethylene terephthalate (PET bottles and the diethyl phthalate (DEP metabolite MEP. With regard to health effects, significant associations of MEP in urine with headache, repeated coughing, diarrhoea, and hormonal problems were observed. MBzP was associated with repeated coughing and MEHP was associated with itching.

    Japan's 2008 health policy focuses more than ever on health education for behaviour change and outcome measures for physical health status. This is at odds with contemporary health promotion and health education, which frame health as a resource for everyday life and indicate that the evaluation of interventions should measure broader aspects of health rather than just physical aspects. The application of a combination of different health communication models and theories allows for a customized approach, depending on the types of change that are being sought, and can lead to increased relevance as well as a better fit when it comes to evaluating the achievement of broad health promotion goals. This article explores the application of the Outcome Model for Health Promotion to a two-year health education intervention in Kushima, Japan. This model measures program effectiveness from four aspects: physical health outcomes; intermediate health outcomes; health promotion outcomes; and health promotion actions. A quantitative and qualitative longitudinal, mixed model study design and methods were used for the analysis. Data was taken from health exams, structured interviews, and participant observations collected from 67 participants at four times over two years. This intervention relied primarily on health education and communication to achieve mental and social health outcomes more significantly and faster than physical health outcomes. The importance of moving outcome measurement beyond direct health achievements is discussed in light of the relationships between physical, mental, and social health and its determinants, and our results.

    Since ancient times, numerous health beneficial effects have been attributed to chocolate, closing up its consumption to a therapeutic use. The present study reviews some relevant studies about chocolate (and its bioactive compounds) on some cardiovascular risk factors and stresses the need of future studies. The consumption of cocoa/ chocolate (i) increases plasma antioxidant capacity, (ii) diminishes platelet function and inflammation, and (iii) decreases diastolic and systolic arterial pressures. Data currently available indicate that daily consumption of cocoa-rich chocolate (rich in polyphenols) may at least partially lower cardiovascular disease risk. Further studies are required in order to establish the bioavailability and mechanisms of action of bioactive compounds in chocolate. The study of the interaction of chocolate and its components with candidate genes will also supply necessary information regarding the individuals best suited to benefit from a potential cardiovascular disease treatment with chocolate.

    Radioactive radon gas is widely considered to be a health hazard by environmental agencies in the United States and in Europe. Yet despite the warnings of these agencies, thousands of people annually expose themselves to radon for therapeutic purposes, in facilities ranging from rustic old mines, to upscale spas and clinics. The inert natural radioactive gas radon has been used since the beginning of the century in the treatment of rheumatic diseases. In many places in the world, radon is used for therapeutic purposes for various diseases. Radon inhalation is applied in a thermal gallery with atmospheric radon concentrations up to 100 kBq/m3, elevated temperature up to 41 EC , and humidity close to 100%, or in the form of radon baths where Rn is emanated from water with high natural Rn activity. Frequently, a combination of both treatment procedures is applied. Evidence from empirical experience and from clinical observational studies suggests that radon has analgesic, anti inflammatory and immune-stimulating effects. Ozone is one of nature's most powerful oxidants. It increases the effectiveness of the antioxidant enzyme system, which scavenge excess free radicals in the body. It is used in water purification and sewage treatment and is now being applied medically to treat many diseases from wounds and colitis to cancer, stroke and AIDS. According to the dosage and concentration range, medical ozone is a pharmaceutical agent that exerts specific properties and a well-defined range of efficacy. This paper describes the medical application of environmental gases: radon and ozone

  15. Allyl nitrile: Toxicity and health effects.

    Tanii, Hideji

    2017-03-28

    Allyl nitrile (3-butenenitrile) occurs naturally in the environment, in particular, in cruciferous vegetables, indicating a possible daily intake of the compound. There is no report on actual health effects of allyl nitrile in humans, although it is possible that individuals in the environment are at a risk of exposure to allyl nitrile. However, little is known about its quantitative assessment for the environment and bioactivity in the body. This study provides a review of previous accumulated studies on allyl nitrile. Published literature on allyl nitrile was examined for findings on toxicity, metabolism, risk of various cancers, generation, intake estimates, and low-dose effects in the body. High doses of allyl nitrile produce toxicity characterized by behavioral abnormalities, which are considered to be produced by an active metabolite, 3,4-epoxybutyronitrile. Cruciferous vegetables have been shown to have a potential role in reducing various cancers. Hydrolysis of the glucosinolate sinigrin, rich in cruciferous vegetables, results in the generation of allyl nitrile. An intake of allyl nitrile is estimated at 0.12 μmol/kg body weight in Japan. Repeated exposure to low doses of allyl nitrile upregulates antioxidant/phase II enzymes in various tissues; this may contribute to a reduction in neurotoxicity and skin inflammation. These high and low doses are far more than the intake estimate. Allyl nitrile in the environment is a compound with diverse bioactivities in the body, characterized by inducing behavioral abnormalities at high doses and some antioxidant/phase II enzymes at low doses.

    Kono, K

    1994-12-01

    Fluoride, the ionic form of fluorine, is a natural component of the biosphere and 13th most abundant element in the crust of the earth. It is, therefore, found in a wide range of concentrations in virtually all inanimate and living things. Many trace elements perform a definite function in human metabolism and the question of the value of fluoride, always found in the body, has been raised. Much evidence suggesting that the inclusion of fluoride in drinking water has beneficial as well as adverse effects on human health was obtained. Either alone or in combination with calcium and/or vitamin D, it is used in high daily doses for the treatment of osteoporosis. Although organic fluorine compounds are used in medicine and commerce, the inorganic fluorine compounds are of greater importance toxicologically because they are more readily available. The major pathway of fluoride elimination from the human body is via the kidney. When renal function deteriorates, the ability to excrete fluoride markedly decreases, possibly resulting in greater retention of fluoride in the body. At this point, more research is needed to evaluate the effects of physiological variables on the fluoride metabolism in humans.

    Arsenic (As) is ubiquitous in nature and humans being exposed to arsenic via atmospheric air, ground water and food sources are certain. Major sources of arsenic contamination could be either through geological or via anthropogenic activities. In physiological individuals, organ system is described as group of organs that transact collectively and associate with other systems for conventional body functions. Arsenic has been associated with persuading a variety of complications in body organ systems: integumentary, nervous, respiratory, cardiovascular, hematopoietic, immune, endocrine, hepatic, renal, reproductive system and development. In this review, we outline the effects of arsenic on the human body with a main focus on assorted organ systems with respective disease conditions. Additionally, underlying mechanisms of disease development in each organ system due to arsenic have also been explored. Strikingly, arsenic has been able to induce epigenetic changes (in utero) and genetic mutations (a leading cause of cancer) in the body. Occurrence of various arsenic induced health effects involving emerging areas such as epigenetics and cancer along with their respective mechanisms are also briefly discussed.

    In this study, the influence of source term release parameters on the health effects was examined. This is very useful in identifying the relative importance of release parameters and can be an important factor in developing a strategy for reducing offsite risks. The release parameters investigated in this study are release height, heat content, fuel burnup, release time, release duration, and warning time. The health effects affected by the change of release parameters are early fatalities, cancer fatalities, early injuries, cancer injuries, early fatality risk, population weighted early fatality risk, population weighted cancer fatality risk, effective whole body population dose, population exceeding an early acute red bone marrow dose of 1.5 Sv, and distance at which early fatalities are expected to occur. As release height increases, the values of early health effects such as early fatalities and injuries decrease. However, the release height dose not have significant influences on late health effects. The values of both early and late health effects decrease as heat content increases. The increase fuel burnup, i.e., the increase of core inventories increases the late health effects, however, has small influence on the early health effects. But, the number of early injuries increases as the fuel burnup increases. The effects of release time increase shows very similar influence on both the early and late health effects. As the release time increases to 2 hours, the values of health effects increase and then decrease rapidly. As release duration increases, the values of late health effects increase slightly, however, the values of early health effects decrease. As warning time increases to 2 hours, the values of late health effects decrease and then shows no variation. The number of early injuries decreases rapidly as the warning time increases to 2 hours. However, the number of early fatalities and the early fatality risk increase as the warning time increases

    On the 26th of April 1986, the 4th unit of the Chernobyl Nuclear Power Plant in the former Soviet Union exploded, following a scheduled but not-well-planned testing of a turbo-generator prior to a shutdown of the reactor. This led to a release of large amounts of radioactive material into the atmosphere, resulting in a cloud not only over in the Soviet Union, but due to prevailing meteorological condition, over the Eastern Europe as well. Over the past ten years, a large number of agencies in the areas of human health and hygiene, agriculture and veterinary sciences in addition to those involved in radiation protection and radiation safety have studied the impact of the accident. These studies were also extended to evaluate and mitigate the consequences. The accident has been a warning, and has provided lessons in mitigating the consequences of any industrial accident. Newer perspectives have emerged in the area of early diagnosis and treatment of the acute effects of radiation. Research in the areas of genetics, molecular biology and radiation biology will contribute to better medical care in future. (author). 3 tabs

  5. Effect of Alcohol to Oral Health

    Full Text Available According to the World Health Organization there are almost two billion people worldwide who consume alcohol on a regular basis. It’s a common abuse and almost 80 million are diagnozed with “alcohol abuse disorders” (WHO 2002, 2004. Excessive alcohol consumption is related to more than 60 different medical conditions, as suicide, homicide and different forms of accidents. Some conditions are acute, while other conditions such as liver cirrhosis, chronic pancreatitis, haemorrhagic stroke and various forms of cancer, are chronic consequences. Non-carious destructions of teeth like dental erosion are also associated with frequent alcohol consumption, because of precipitation of salivary proline-rich proteins caused by polyphenols present in most alcoholic drinks. The high concentration of organic and inorganic acids and the habit of keeping the alcoholic drink in the mouth can cause chronic inflammations of the soft tissues in the mouth and can increase the negative side effects from metals of crowns, bridges, orthodontic devises and various restorations. A literature review has been made due to the authors clinical observations and experiences.

  6. The effect of individual factors on health behaviors among college students: the mediating effects of eHealth literacy.

    College students' health behavior is a topic that deserves attention. Individual factors and eHealth literacy may affect an individual's health behaviors. The integrative model of eHealth use (IMeHU) provides a parsimonious account of the connections among the digital divide, health care disparities, and the unequal distribution and use of communication technologies. However, few studies have explored the associations among individual factors, eHealth literacy, and health behaviors, and IMeHU has not been empirically investigated. This study examines the associations among individual factors, eHealth literacy, and health behaviors using IMeHU. The Health Behavior Scale is a 12-item instrument developed to measure college students' eating, exercise, and sleep behaviors. The eHealth Literacy Scale is a 12-item instrument designed to measure college students' functional, interactive, and critical eHealth literacy. A nationally representative sample of 525 valid college students in Taiwan was surveyed. A questionnaire was administered to collect background information about participants' health status, degree of health concern, major, and the frequency with which they engaged in health-related discussions. This study used Amos 6.0 to conduct a confirmatory factor analysis to identify the best measurement models for the eHealth Literacy Scale and the Health Behavior Scale. We then conducted a multiple regression analysis to examine the associations among individual factors, eHealth literacy, and health behaviors. Additionally, causal steps approach was used to explore indirect (mediating) effects and Sobel tests were used to test the significance of the mediating effects. The study found that perceptions of better health status (t520=2.14-6.12, PeHealth literacy and adoption of healthy eating, exercise, and sleep behaviors. Moreover, eHealth literacy played an intermediary role in the association between individual factors and health behaviors (Sobel test=2.09-2.72, PeHealth

    Ruhi Selcuk TABAK

    2006-04-01

    Full Text Available Main objective of this study is to investigate the relationships between health locus of control perceptions and health behaviours of adolescents as well as the effectiveness of lectures on health locus of control to them. The subjects of our study are 192 students in 6 groups of the 9. Grade students of a high school. Three groups of 108 students were randomly selected as the experiment group who were subjected to 4 class-hours specific lectures on health locus of control. The rest 84 students constituted the control group. A 34-item questionnaire for health behaviours and the Multidimensional Health Locus of Control Scale (MHLOC, were filled by the students before and after the lectures. The lectures on health locus of control increased the perception of internal health locus of control of adolescents while decreasing chance health locus of control. The differences between experiment and control groups in this aspect were found to be statistically significant. Internal health locus of control is the main source for the increase of responsibility and management of individuals on their health. The relations that were detected between students’ health behaviours and information solicitation and their perceptions of health locus of control showed that the students with higher internal health locus of control are more eager to be responsible and active for their health, especially, for the health behaviours such as physical exercise, smoking, tooth-brushing, medical check-ups so on.

  12. Cost-effectiveness and the socialization of health care.

    Science.gov (United States)

    Musgrove, P

    1995-01-01

    The more health care is socialized, the more cost-effectiveness is an appropriate criterion for expenditure. Utility-maximizing individuals, facing divisibility of health care purchases and declining marginal health gains, and complete information about probable health improvements, should buy health care according to its cost-effectiveness. Absent these features, individual health spending will not be cost-effective; and in any case, differences in personal utilities and risk aversion will not lead to the same ranking of health care interventions for everyone. Private insurance frees consumers from concern for cost, which undermines cost-effectiveness, but lets them emphasize effectiveness, which favors value for money. This is most important for costly and cost-effective interventions, especially for poor people. Cost-effectiveness is more appropriate and easier to achieve under second-party insurance. More complete socialization of health care, via public finance, can yield greater efficiency by making insurance compulsory. Cost-effectiveness is also more attractive when taxpayers subsidize others' care: needs (effectiveness) take precedence over wants (utility). The gain in effectiveness may be greater, and the welfare loss from Pareto non-optimality smaller, in poor countries than in rich ones.

  13. The Effect of Childhood Health Status on Adult Health in China.

    2018-01-26

    Childhood health in China was poor in the 1950s and 1960s because of limited nutrition. In the last three decades, China has distinguished itself through its tremendous economic growth and improvements in health and nutrition. However, prior to such growth, access to good nutrition was more variable, with potentially important implications, not only for childhood health, but also for adult health, because of its long-term effects lasting into adulthood. To shed light on these issues, this study examined the long-run association between childhood health and adult health outcomes among a middle-aged Chinese population and addresses the endogeneity of childhood health. A nationwide database from the 2011 China Health and Retirement Longitudinal Study (CHARLS) was employed. Three adult health outcomes variables were used: self-reported health status, cognition, and physical function. The local variation in grain production in the subjects' fetal period and the first 24 months following birth was employed as an instrument for childhood health in order to correct for its endogeneity. Childhood health recalled by the respondents was positively and significantly associated with their adult health outcomes in terms of self-reported health status, cognition, and physical function in single-equation estimates that did not correct for the endogeneity of childhood health. A good childhood health status increased the probabilities of good adult health, good adult cognitive function, and good adult physical function by 16% (95% CI: 13-18%), 13% (95% CI: 10-15%), and 14% (95% CI: 12-17%), respectively. After correcting for endogeneity, the estimated effects of good childhood health were consistent but stronger. We also studied the male and female populations separately, finding that the positive effects of childhood health on adult health were larger for males. In China, childhood health significantly affects adult health. This suggests that early interventions to promote

Part 1 was published in April ( Lambert and Keogh 2014 ). This article explains how to detect low levels of health literacy among parents and children, and outlines the challenges to assessing health literacy levels, including the stigma and discrimination some people experience. Some basic healthcare communication strategies for supporting health literacy in practice are suggested.

    1983-01-01

    The constraints facing health education include: the fragmentation and dispersal of health-educational services among different agencies and personnel; lack of policy guidelines; ineffectively organized and inefficiently managed health education systems; poor hierarchical status and inadequacy of resources. To resolve these constraints, national health education systems in health agencies should be developed on the basis of stipulated guidelines that could ensure their viability, efficiency and effectiveness. A study at the African Regional Health Education Centre, Ibadan, Nigeria, has yielded thirty synthesized guidelines. The "guidelines" were empirically tested as an evaluation tool by assessing the operational and organizational status of Oyo State Health Education Unit, Ibadan, Nigeria. These guidelines are adaptable to local conditions to enhance the re-organization, re-orientation and consolidation of health education in national health agencies.

  20. Coalfield health effects: Variation in health across former coalfield areas in England

    Regions affected by deindustrialisation are often characterised by unfavourable local health profiles. This was the situation in coalfield areas in England, where the scale and suddenness of the job losses in the 1980s and 1990s left these communities experiencing difficult socioeconomic conditions, and associated poor health status. Using data from the Health Survey for England, this paper examines whether poorer health outcomes still characterise coalfield areas today. Findings confirm a 'coalfield health effect' related to limiting long-term illness. With regards to self reported general health and mental health outcomes, results are less clear. The population health profile of coalfield communities is not homogeneous, with some coalfield communities faring worse than others, indicating more localised health issues.

  1. On Effective Graphic Communication of Health Inequality: Considerations for Health Policy Researchers.

    Policy Points: Effective graphs can be a powerful tool in communicating health inequality. The choice of graphs is often based on preferences and familiarity rather than science. According to the literature on graph perception, effective graphs allow human brains to decode visual cues easily. Dot charts are easier to decode than bar charts, and thus they are more effective. Dot charts are a flexible and versatile way to display information about health inequality. Consistent with the health risk communication literature, the captions accompanying health inequality graphs should provide a numerical, explicitly calculated description of health inequality, expressed in absolute and relative terms, from carefully thought-out perspectives. Graphs are an essential tool for communicating health inequality, a key health policy concern. The choice of graphs is often driven by personal preferences and familiarity. Our article is aimed at health policy researchers developing health inequality graphs for policy and scientific audiences and seeks to (1) raise awareness of the effective use of graphs in communicating health inequality; (2) advocate for a particular type of graph (ie, dot charts) to depict health inequality; and (3) suggest key considerations for the captions accompanying health inequality graphs. Using composite review methods, we selected the prevailing recommendations for improving graphs in scientific reporting. To find the origins of these recommendations, we reviewed the literature on graph perception and then applied what we learned to the context of health inequality. In addition, drawing from the numeracy literature in health risk communication, we examined numeric and verbal formats to explain health inequality graphs. Many disciplines offer commonsense recommendations for visually presenting quantitative data. The literature on graph perception, which defines effective graphs as those allowing the easy decoding of visual cues in human brains, shows

  2. The effect of health shocks on smoking and obesity.

    To investigate whether negative changes in their own health (i.e. health shocks) or in that of a smoking or obese household member, lead smokers to quit smoking and obese individuals to lose weight. The study is informed by economic models ('rational addiction' and 'demand for health' models) which offer hypotheses on the relationship between health shocks and health-related behaviour. Each hypothesis was tested applying a discrete-time hazard model with random effects using up to ten waves of the German Socioeconomic Panel (GSOEP) and statistics on cigarette, food and beverage prices provided by the Federal Statistical Office. Health shocks had a significant positive impact on the probability that smokers quit during the same year in which they experienced the health shock. Health shocks of a smoking household member between year t-2 and t-1 also motivated smoking cessation, although statistical evidence for this was weaker. Health shocks experienced by obese individuals or their household members had, on the other hand, no significant effect on weight loss, as measured by changes in Body Mass Index (BMI). The results of the study suggest that smokers are aware of the risks associated with tobacco consumption, know about effective strategies to quit smoking, and are willing to quit for health-related reasons. In contrast, there was no evidence for changes in health-related behaviour among obese individuals after a health shock.

    The widespread adoption of health information technology (IT) will help contain health care costs by decreasing inefficiencies in healthcare delivery. Theoretically, health IT could lower hospitals' malpractice insurance premiums (MIPs) and improve the quality of care by reducing the number and size of malpractice. This study examines the relationship between health IT investment and MIP using California hospital data from 2006 to 2007. To examine the effect of hospital IT on malpractice insurance expense, a generalized estimating equation (GEE) was employed. It was found that health IT investment was not negatively associated with MIP. Health IT was reported to reduce medical error and improve efficiency. Thus, it may reduce malpractice claims from patients, which will reduce malpractice insurance expenses for hospitals. However, health IT adoption could lead to increases in MIPs. For example, we expect increases in MIPs of about 1.2% and 1.5%, respectively, when health IT and labor increase by 10%. This study examined the effect of health IT investment on MIPs controlling other hospital and market, and volume characteristics. Against our expectation, we found that health IT investment was not negatively associated with MIP. There may be some possible reasons that the real effect of health IT on MIPs was not observed; barriers including communication problems among health ITs, shorter sample period, lower IT investment, and lack of a quality of care measure as a moderating variable.

  4. Health effects attributable to coal and nuclear fuel cycle alternatives

    International Nuclear Information System (INIS)

    Gotchy, R.L.

    1977-09-01

    Estimates of mortality and morbidity are presented based on present-day knowledge of health effects resulting from current component designs and operations of the fuel cycles, and anticipated emission rates and occupational exposure for the various fuel cycle facilities expected to go into operation in approximately the 1975-1985 period. It was concluded that, although there are large uncertainties in the estimates of potential health effects, the coal fuel cycle alternative has a greater health impact on man than the uranium fuel cycle. However, the increased risk of health effects for either fuel cycle represents a very small incremental risk to the average individual in the public

    The Nuclear Regulatory Commission (NRC) has sponsored several studies to identify and quantify, through the use of models, the potential health effects of accidental releases of radionuclides from nuclear power plants. The Reactor Safety Study provided the basis for most of the earlier estimates related to these health effects. Subsequent efforts by NRC-supported groups resulted in improved health effects models that were published in the report entitled open-quotes Health Effects Models for Nuclear Power Plant Consequence Analysisclose quotes, NUREG/CR-4214, 1985 and revised further in the 1989 report NUREG/CR-4214, Rev. 1, Part 2. The health effects models presented in the 1989 NUREG/CR-4214 report were developed for exposure to low-linear energy transfer (LET) (beta and gamma) radiation based on the best scientific information available at that time. Since the 1989 report was published, two addenda to that report have been prepared to (1) incorporate other scientific information related to low-LET health effects models and (2) extend the models to consider the possible health consequences of the addition of alpha-emitting radionuclides to the exposure source term. The first addendum report, entitled open-quotes Health Effects Models for Nuclear Power Plant Accident Consequence Analysis, Modifications of Models Resulting from Recent Reports on Health Effects of Ionizing Radiation, Low LET Radiation, Part 2: Scientific Bases for Health Effects Models,close quotes was published in 1991 as NUREG/CR-4214, Rev. 1, Part 2, Addendum 1. This second addendum addresses the possibility that some fraction of the accident source term from an operating nuclear power plant comprises alpha-emitting radionuclides. Consideration of chronic high-LET exposure from alpha radiation as well as acute and chronic exposure to low-LET beta and gamma radiations is a reasonable extension of the health effects model

    Full Text Available This article provides examples of adverse health effects, including weather-related injury, food insecurity, mental health issues, and water infrastructure damage, and the responses to these effects that are currently being applied in two Northwest Alaska communities.In Northwest Alaska, warming is resulting in a broad range of unusual weather and environmental conditions, including delayed freeze-up, earlier breakup, storm surge, coastal erosion, and thawing permafrost. These are just some of the climate impacts that are driving concerns about weather-related injury, the spread of disease, mental health issues, infrastructure damage, and food and water security. Local leaders are challenged to identify appropriate adaptation strategies to address climate impacts and related health effects.The tribal health system is combining local observations, traditional knowledge, and western science to perform community-specific climate change health impact assessments. Local leaders are applying this information to develop adaptation responses.The Alaska Native Tribal Health Consortium will describe relationships between climate impacts and health effects and provide examples of community-scaled adaptation actions currently being applied in Northwest Alaska.Climate change is increasing vulnerability to injury, disease, mental stress, food insecurity, and water insecurity. Northwest communities are applying adaptation approaches that are both specific and appropriate.The health impact assessment process is effective in raising awareness, encouraging discussion, engaging partners, and implementing adaptation planning. With community-specific information, local leaders are applying health protective adaptation measures.

    The ICP was specifically designed to study issues related to persons still living on highly contaminated territories. These persons were continuing to receive radiation exposure and there were pressing issues related to intervention and potential dose reduction. It was well known that there were hundreds of thousands of emergency workers who had been exposed, but in 1990 there was no possibility for dose reduction in these groups. Both the International Red Cross and the World Health Organization had sent health assessment teams to the area in 1988-89. These were relatively small projects, but reached essentially the same conclusions as the ICP did

    Various types of disasters, such as natural disasters, industrial accidents and crimes, often occur in the workplace and many workers are involved in them. They are not only directly injured but also exposed to health hazards, such as terrible experiences and chemical materials. Occupational health specialists are expected to act to minimize the adverse health effects from them speedily and appropriately. It is assumed that learning from past cases is effective for such occupational health activities. Accordingly, we conducted a literature review about the health effects on workers in disasters. Relevant literature was searched in PubMed. Twenty four studies were extracted by our criteria. In this review, subjects were limited to general workers by excluding professional workers, such as emergency services and firefighters. The health effects were examined as follows: mental health (13 articles), respiratory (5), cardiovascular (2), musculoskeletal (1), skin (1), nervous (1), and general (1). It was obvious that few studies on general workers were published when considering large number of disasters in the past. Factors that affect health outcomes were categorized into ① those related to devastation of environment of work and life due to disaster, and ② those related to health hazards due to disasters. Knowledge from the review will support the activities of occupational health specialists during disasters, but additional studies are needed.

    2017-12-01

    Differences in health care satisfaction can alter patterns of health care utilization and so affect health outcomes, but little is known about variation in satisfaction in relation to immigration status. Health care satisfaction is analyzed with survey data from state public health program patients. Overall health care satisfaction is higher for first generation Hispanic immigrants and lower among those in the second generation compared to white Americans-consistent with the pattern termed the "healthy migrant effect." This pattern is more pronounced for Portuguese-speaking immigrants and is not explained by self-reported health, communication ability or acculturation. Satisfaction with specific aspects of health care follows different patterns that may be explained by differences in experiences and culture. As anticipated by segmented assimilation theory, we find variation in cross-generational patterns of health care satisfaction both within and between ethnic groups. This variation indicates the importance of distinguishing Portuguese-speakers from Spanish-speakers and of taking into account differences in the ways they are able to communicate with health care providers as well as differences in their orientations toward health care. Our disparate findings with other immigrant groups also reinforce limiting expectations of a "healthy migrant effect" to Latinos. Finally, the variable influences on different satisfaction measures indicate the importance of considering the relative influence of culturally-based orientations and health care experiences on the specific outcomes measured, with particular sensitivity to acceptance of individualized standards of care.

    To effectively reduce health risks at the animal-human-ecosystems interface, a One Health strategy is crucially important to create strong national and regional animal health systems that are well coordinated with strong public health systems. Animal diseases, particularly those caused by new and emerging zoonotic pathogens, must be effectively controlled at their source to reduce their potentially devastating impact upon both animal and human health. As the international organisation responsible for developing standards, guidelines and recommendations for animal health, the World Organisation for Animal Health (OIE) plays an important role in minimising animal and public health risks attributable to zoonoses and other animal diseases, which can have severe consequences for global food safety and security. National Veterinary Services, which implement OIE animal health and welfare standards and other measures, are the first line of defence against these diseases, and must have the capacity to meet the core requirements necessary for their diagnosis and control. The OIE works collaboratively with the World Health Organization and Food and Agriculture Organization of the United Nations to improve the ability of national animal and public health systems to respond to current and emerging animal health risks with public health consequences. In addition to improving and aligning national laboratory capacities in high-risk areas, the OIE collaborates on One Health-oriented projects for key diseases, establishing model frameworks which can be applied to manage other existing and emerging priority diseases. This article reviews the role and activities of the OIE in strengthening the national Veterinary Services of its Member Countries for a more effective and sustainable One Health collaboration.

    Cogan, John F.; Hubbard, R. Glenn; Kessler, Daniel P.

    2011-01-01

    In this paper, we estimate the effect of the tax preference for health insurance on health care spending using data from the Medical Expenditure Panel Surveys from 1996–2005. We use the fact that Social Security taxes are only levied on earnings below a statutory threshold to identify the impact of the tax preference. Because employer-sponsored health insurance premiums are excluded from Social Security payroll taxes, workers who earn just below the Social Security tax threshold receive a larger tax preference for health insurance than workers who earn just above it. We find a significant effect of the tax preference, consistent with previous research. PMID:22500056

    Objectives The broad goal of contemporary prenatal care is to promote the health of the mother, child, and family through the pregnancy, delivery, and the child’s development. Although the vast majority of mothers giving birth in developed countries receive prenatal care, past research has not found compelling evidence that early or adequate prenatal care has favorable effects on birth outcomes. It is possible that prenatal care confers health benefits to the child that do not become apparent until after the perinatal period. Methods Using data from a national urban birth cohort study in the U.S., we estimate the effects of prenatal care on four markers of child health at age 5—maternal-reported health status, asthma diagnosis, overweight, and height. We implement a number of different strategies to address the issue of potential omitted variables bias as well as a large number of specification checks to validate the findings. Results and Conclusions Prenatal care, defined a number of different ways, does not appear to have any effect on the outcomes examined. The findings are robust and suggest that routine health care encounters during the prenatal period could potentially be used more effectively to enhance children’s health trajectories. However, future research is needed to explore the effects of prenatal care on additional child health and developmental outcomes as well as the effects of preconceptional and maternal lifetime helathcare on child health.

    2014-02-01

    The health benefits of exercise are well known. Many of the most accessible forms of exercise, such as walking, cycling, and running often occur outdoors. This means that exercising outdoors may increase exposure to urban air pollution. Regular exercise plays a key role in improving some of the physiologic mechanisms and health outcomes that air pollution exposure may exacerbate. This problem presents an interesting challenge of balancing the beneficial effects of exercise along with the detrimental effects of air pollution upon health. This article summarizes the pulmonary, cardiovascular, cognitive, and systemic health effects of exposure to particulate matter, ozone, and carbon monoxide during exercise. It also summarizes how air pollution exposure affects maximal oxygen consumption and exercise performance. This article highlights ways in which exercisers could mitigate the adverse health effects of air pollution exposure during exercise and draws attention to the potential importance of land use planning in selecting exercise facilities.

    Shared commutes to work, such as vanpooling, benefit the environment and provide economic gain for riders in terms of fuel costs, parking fees, and personal vehicle wear and tear. Although ride sharing is commonly believed to promote health through stress reduction, published evidence on this topic is limited, and findings vary. This study explored the perceived health and well-being of vanpoolers using a qualitative, descriptive design. Five focus groups of vanpoolers and two individual interviews with drivers were conducted (N=40 participants). Stress, change in sleep patterns, and interpersonal relationships emerged as major themes. Employee insights about the impact of vanpooling on work productivity and how employer commitment to the vanpool program influences the vanpool experience also were important findings. © 2015 The Author(s).

    (1) To investigate the contribution of job characteristics and personal characteristics to the explanation of health effects among university personnel; (2) to investigate the differences between scientific personnel (SP) and non-scientific personnel (NSP); (3) to investigate whether health effects occurred one after another. The well being at work of employees at a Dutch university (n=2,522) was investigated by means of a questionnaire. A model was constructed in which several job and personal characteristics were set out against health effects. The latter were assumed to occur in phases: decreased "job satisfaction" as an early effect, followed by increased "tension" and "emotional exhaustion", and possibly also by increased "perceived health complaints". The contribution of job and personal characteristics to the explanation of health effects was investigated by means of linear regression analysis, with separate analyses for SP and NSP. Positive job characteristics, especially professional expertise and work variety, contributed to the explanation of "job satisfaction". The major contributors to "tension" and "emotional exhaustion" were negative characteristics, such as work pressure. Besides the negative aspects, the major contributors to the explanation of "perceived health complaints" were sex, age and other health effects. In NSP, social support contributed to the explanation of "tension" and "emotional exhaustion", but not in SP. The explained variance of "job satisfaction" by the positive job characteristics in NSP was much higher than that in SP. To investigate whether health effects occurred one after another, we considered explained variance. Explained variance in "job satisfaction" was much higher than in "perceived health complaints". "Emotional exhaustion" and "tension" were in between. Contrary to expectations, decision latitude and social support played only minor roles. Also, the differences between SP and NSP were smaller than expected. As

    2017-02-01

    Development aid for health increased dramatically during the past two decades, raising concerns about inefficiency and lack of coherence among the growing number of global health donors. However, we lack a framework for how donor proliferation affects health program performance to inform theory-based evaluation of aid effectiveness policies. A review of academic and gray literature was conducted. Data were extracted from the literature sample on study design and evidence for hypothesized effects of donor proliferation on health program performance, which were iteratively grouped into categories and mapped into a new conceptual framework. In the framework, increases in the number of donors are hypothesized to increase inter-donor competition, transaction costs, donor poaching of recipient staff, recipient control over aid, and donor fragmentation, and to decrease donors' sense of accountability for overall development outcomes. There is mixed evidence on whether donor proliferation increases or decreases aid volume. These primary effects in turn affect donor innovation, information hoarding, and aid disbursement volatility, as well as recipient country health budget levels, human resource capacity, and corruption, and the determinants of health program performance. The net effect of donor proliferation on health will vary depending on the magnitude of the framework's competing effects in specific country settings. The conceptual framework provides a foundation for improving design of aid effectiveness practices to mitigate negative effects from donor proliferation while preserving its potential benefits.

    Whether health insurance matters for health has long been a central issue for debate when assessing the full value of health insurance coverage in both developed and developing countries. In 2007, the government-led Urban Resident Basic Medical Insurance (URBMI) program was piloted in China, followed by a nationwide implementation in 2009. Different premium subsidies by government across cities and groups provide a unique opportunity to employ the instrumental variables estimation approach to identify the causal effects of health insurance on health. Using a national panel survey of the URBMI, we find that URBMI beneficiaries experience statistically better health than the uninsured. Furthermore, the insurance health benefit appears to be stronger for groups with disadvantaged education and income than for their counterparts. In addition, the insured receive more and better inpatient care, without paying more for services. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

    Apart from the dramatic increase in thyroid cancer in those exposed as children, there is no evidence to date of a major public health impact of the radiation exposure from the Chernobyl accident in the three most affected countries. Although some increases in the frequency of cancer in exposed populations have been reported, these results are difficult to interpret, mainly because of differences in the intensity and method of follow-up between exposed populations and the general population to which they are compared. If the experience of atomic bomb survivors and of other exposed populations is applicable, the major radiological impact of the accident will be cancer and the total lifetime numbers of excess cancers will be greatest among the liquidators and among the residents of contaminated territories, of the order of 2,000 to 2,500. These increases would be difficult to detect epidemiologically against an expected background number of 41,500 and 433,000 respectively (size of the exposed populations: 200,000 and 3,700,000, respectively). It is noted, however, that the exposures received by populations exposed as a result of Chernobyl are different (in type and pattern) from those of atomic bomb survivors. Predictions derived from these populations are therefore uncertain. Indeed, the extent of the increase in thyroid cancer incidence in persons exposed as children was not foreseen. In addition, only ten years have passed since the accident. It is essential therefore that monitoring of the health of the population be continued in order to assess the public health impact of the accident, even if, apart from leukemia among liquidators, little detectable increase of cancers due to radiation from the Chernobyl accident is expected

    Apart from the dramatic increase in thyroid cancer in those exposed as children, there is no evidence to date of a major public health impact of the radiation exposure from the Chernobyl accident in the three most affected countries. Although some increases in the frequency of cancer in exposed populations have been reported, these results are difficult to interpret, mainly because of differences in the intensity and method of follow-up between exposed populations and the general population to which they are compared. If the experience of atomic bomb survivors and of other exposed populations is applicable, the major radiological impact of the accident will be cancer and the total lifetime numbers of excess cancers will be greatest among the liquidators and among the residents of contaminated territories, of the order of 2,000 to 2,500.

    Dr. Upton notes the wide misunderstanding of the health risks from nuclear energy because of its association with nuclear weapons, but he also notes and reviews a broad consensus within the scientific community on the risks of low-level irradiation. The author makes the point that society must be involved in determining the level of acceptable risk, and that society has a right to expect that risk assessments will be technically sound. The author uses a series of tables to present numerical interpretations of the scientific consensus, which finds the risk to be relatively small. 30 references, 11 tables

    International Nuclear Information System (INIS)

    1975-11-01

    stitutt for Atomenergi (IFA) and Norsk Institutt for Luftforskning (NILU) have undertaken a joint project with the ultimate purpose of comparing the relative air pollution health effects of gas-fired, oil-fired and uranium-fueled electric power generating plants. Phase I of the project includes a literature review on pollutant emissions and their health effects. The methods which have previouously been used to compare the relative health effects are also reviewed. The radioactive effluents from nuclear power plants are tabulated and the health effects discussed on the basis of data from Hiroshima and Nagasaki, medical irradiation therapy and studies of USAEC and UKAEA employees. It is pointed out that there is no indication that chronic low-level radiation has somatic effects, and the Japanese data gives no conclusive indication of genetic effects. Background irradiation in Kerala and Guarapari and in USA is also cited. Following a brief presentation of the principal air pollutants from fossil fuels a number of studies of 'smog' incidents in the UK and USA are discussed, and a prediction equation based on multiple regression analysis is presented. Finally the methods of comparing the health effects from nuclear and fossil-fuel plants are discussed. In an appendix Lave and Freeburg's study 'Health effects of electricity generation from coal, oil and nuclear fuel' is evaluated. (JIW)

    2017-03-01

    Prior research indicates that workplace wellness programmes (WWPs) are generally associated with lowered healthcare costs and improved employee health. Despite the importance of mental well-being in workplace productivity and attendance, few WWP studies have focused on improvements in psychological well-being. To examine the effects of the Bruin Health Improvement Program (BHIP), a 3-month exercise and nutrition WWP, on seven domains of health: physical and mental health, stress, energy level, social satisfaction, self-efficacy and quality of life. Using data from BHIP completers, we conducted multiple one-way multivariate analyses of variance and follow-up univariate t-tests to examine changes in physical and mental health, stress, energy level, social satisfaction, self-efficacy and quality of life. Effect sizes were also calculated post hoc to determine the magnitude of each effect. Results for the 281 participants reveal significant improvements across all seven domains (P < 0.001). Effect sizes ranged from 0.19 to 0.67. This study is unique in revealing the effects of a WWP on multiple domains of psychological well-being. Given rising healthcare costs associated with mental health, targeting mental health through WWP may be an effective strategy for reducing indirect healthcare costs associated with absenteeism and presenteeism. © The Author 2016.

    2007-09-20

    Besides providing optimal nutrition to infants, human milk contains a multitude of immunological components. These components are important for protection against infections and also support the development and maturation of the infant's own immune system. This review focuses on the function of some classical immunocomponents of human milk. Relevant studies are presented that describe health benefits of human milk for the child and of lactation for the mother. Relevant articles were found mainly by searching PubMed. Humoral and cellular components of human milk confer protection against infections in the respiratory--, gastrointestinal--and urinary tract. Human milk also protects premature children from neonatal sepsis and necrotizing enterocolitis. There is evidence that human milk may confer long-term benefits such as lower risk of certain autoimmune diseases, inflammatory bowel disease and probably some malignancies. Human milk possibly affects components of the metabolic syndrome. Recent studies demonstrate long-term health benefits of lactation also for the mother. A reduced incidence of breast cancer is best documented. An increasing number of studies indicate protection against ovarian cancer, rheumatoid arthritis and type II diabetes.

  18. Effects of Migration on Women Mental Health

    Full Text Available People leave their habitats and go to different regions of the world due to various reasons, which is defined as migration. One of the most important changes that have been experienced in migration in the last half century is the increase in women's migration. Women are among the risk groups that are affected by the process of migration at most. A particular attention is attracted to the special requirements of women among groups that are obliged to migrate due to the crisis in their countries. Different lifestyles in the migrated social environment, difficult economic and working conditions, language barrier and relevant adaptation problems all negatively affect the mental health of these women. In order to protect and develop the mental health of migrant women from different cultural groups, it is important to approach these groups as primary risk groups and start multi-directional interventions aimed at their areas required.

  9. An Effective Health and Medical Technical Authority

    Fogarty, Jennifer A.

    2009-01-01

    The NASA Governance model directed the formation of three Technical Authorities, Engineering; Safety and Mission Assurance; and Health and Medical, to ensure that risks are identified and adjudicated efficiently and transparently in concert with the spaceflight programs and projects. The Health and Medical Technical Authority (HMTA) has been implemented at the Johnson Space Center (JSC) and consists of the Chief Medical Office (CMO), the Deputy CMO, and HMTA Delegates. The JSC HMTA achieves the goals of risk identification and adjudication through the discharge of the appropriate technical expertise to human space flight programs and projects and the escalation of issues within program and technical authority boards. The JSC HMTA relies on subject matter experts (SMEs) in the Space Life Sciences Directorate at JSC as well as experts from other Centers to work crew health and performance issues at the technical level, develop requirements, oversee implementation and validation of requirements, and identify risks and non-compliances. Once a risk or potential noncompliance has been identified and reported to the programs or projects, the JSC HMTA begins to track it and closely monitor the program's or project's response. As a risk is developed or a non-compliance negotiated, positions from various levels of decision makers are sought at the program and project control boards. The HMTA may support a program or project position if it is satisfied with the decision making and vetting processes (ex. the subject matter expert voiced his/her concerns and all dissenting opinions were documented) and finds that the position both acknowledges the risk and cost of the mitigation and resolves the issue without changing NASA risk posture. The HMTA may disagree with a program or project position if the NASA risk posture has been elevated or obfuscated. If the HMTA does disagree with the program or project position, it will appeal to successively higher levels of authority so that

    2012-06-01

    A significant gap in evidence characterizes the process of establishing patient-centered health priorities for older men. A cross-sectional postal survey of 2325 Canadian community dwelling men aged 55-97 years old was conducted in 2008 to gauge older men's level of concern for 24 different health items, to determine the impact of age, education and health status on these perceptions, and to ascertain whether men perceive that their health concerns are being attended to. Health issues of greatest concern to men were mobility impairment (64% of respondents), memory loss (64%), and medication side effects (63%). Respondents with lower educational attainment expressed greater concern about their health and were almost 2-fold times more likely to report being concerned about stroke, heart disease and prostate disorders in analyses that controlled for age and health status. Physical and mental health were independently associated with various concerns about health, but old age was not a reliable predictor, with only younger men (erectile dysfunction. Health items of greatest concern to men tended to be those with the lowest screening or counseling rates: these included incontinence, osteoporosis, mobility impairment, falls, anxiety issues, memory loss and depression. An improved consumer-guided agenda for addressing older men's health in the coming decade is urgently required.

    Indoor air quality can be impacted by hundreds of different chemicals. More than 900 different organic compounds alone have been identified in indoor air. Health effects that could arise from exposure to individual pollutants or mixtures of pollutants cover the full range of acute and chronic effects, including largely reversible responses, such as rashes and irritations, to the irreversible toxic and carcinogenic effects. These indoor contaminants are emitted from a large variety of materials and substances that are widespread components of everyday life. Pacific Northwest Laboratory conducted a search of the peer-reviewed literature on health effects associated with indoor air contaminants for the Bonneville Power Administration to aid the agency in the preparation of environmental documents. Results are reported in two volumes. Volume 1 summarizes the results of the search of the peer-reviewed literature on health effects associated with a selected list of indoor air contaminants. In addition, the report discusses potential health effects of polychlorinated biphenyls and chlorofluorocarbons. All references to the literature reviewed are found in this document Volume 2. Volume 2 provides detailed information from the literature reviewed, summarizes potential health effects, reports health hazard ratings, and discusses quantitative estimates of carcinogenic risk in humans and animals.

    Full Text Available In 1980, Clair C. Patterson stated: “Sometime in the near future it probably will be shown that the older urban areas of the United States have been rendered more or less uninhabitable by the millions of tons of poisonous industrial lead residues that have accumulated in cities during the past century”. We live in the near future about which this quote expressed concern. This special volume of 19 papers explores the status of scientific evidence regarding Dr. Patterson’s statement on the habitability of the environments of communities. Authors from 10 countries describe a variety of lead issues in the context of large and small communities, smelter sites, lead industries, lead-based painted houses, and vehicle fuel treated with lead additives dispersed by traffic. These articles represent the microcosm of the larger health issues associated with lead. The challenges of lead risk require a concerted global action for primary prevention.

    In this work, we analyze various consequences of the phenomenon of mobbing on the health of a work sector with special characteristics: the agro fruit sector. For this purpose, we collected data from a sample of 396 workers (61 men and 331 women) belonging to this sector in the Region of Murcia (Spain). A questionnaire with the following measurement instruments was administered: a Spanish adaptation of the revised Negative Acts Questionnaire (Sáez, García, & Llor, 2003), the Psychosomatic Problems Questionnaire (Hock, 1988), and a measure of absenteeism. The results revealed a significant and positive relation between workplace mobbing and psychosomatic symptoms, but not with absenteeism. The implications of the results for future research are discussed.

    Network design is an often overlooked aspect of health insurance contracts. Recent policy factors have resulted in narrower provider networks. We provide plausibly causal evidence on the effect of narrow network plans offered by a large national health insurance carrier in a major metropolitan market. Our econometric design exploits the fact that some firms offer a narrow network plan to their employees and some do not. Our results show that narrow network health plans lead to reductions in health care utilization and spending. We find evidence that narrow networks save money by selecting lower cost providers into the network. Copyright © 2016 Elsevier B.V. All rights reserved.

    The application of mobile health (mHealth) technology in reproductive, maternal, newborn, and child health (RMNCH) is increasing worldwide. However, best practice and the most effective mHealth interventions have not been reviewed systematically. A systematic review and meta-analysis of studies of mHealth interventions for RMNCH around the world were conducted to investigate their characteristics as well as the features and effectiveness of mHealth interventions. Studies of mHealth interventions for RMNCH between January 2011 and December 2016 were retrieved from 6 databases (PubMed, EMBASE, Global Health, China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodicals, and Wanfang Data Knowledge Service Medium). Comparable studies were included in a random-effects meta-analysis for both exclusive breastfeeding (EBF) and antenatal checks (ANC). Descriptive analyses were conducted for mHealth studies with a range of study designs. Analyses of 245 studies were included, including 51 randomized controlled trials (RCTs). Results showed that there are increasing numbers of studies on mHealth interventions for RMNCH. Although 2 meta-analysis, one with 2 RCTs on EBF (odds ratio [OR] 2.03, 95% CI 1.34-3.08, I 2 =25%) and the other with 3 RCTs on ANC (OR 1.43, 95% CI 1.13-1.79, I 2 =78%), showed that mHealth interventions are more effective than usual care, almost half (43%) of RCTs showed negative or unclear results on mHealth interventions. Functions described in mHealth interventions were diverse, and the health stages covered were broad. However, single function or single stage appeared to be dominant among mHealth interventions compared with multiple functions or stages. More rigorous evaluations are needed to draw consistent conclusions and to analyze mHealth products with multiple functions, especially those popular in the app markets. ©Huan Chen, Yanling Chai, Le Dong, Wenyi Niu, Puhong Zhang.

    The main criteria, the methodology, the solutions and parameters that were utilized in the design of the Intermediate and Low Level Radioactive Waste Repository of Abadia de Goias are shortly described. The various design steps are analysed from the preparation of the Safety Analysis Report to the detailing engineering tasks. The safety analysis for the constructed repository had the goal of verifying the magnitude of radioecological impacts corresponding to idealized activity release scenarios, allowing also the possible effects of human intrusion in the repository. These safety studies are intrinsically connected to computer calculations envisaged to simulate the long term performance of the repository. (author) 18 refs., 7 figs., 7 tabs.

    This study investigates the effects of maternal education on child's health and health behavior. We draw on a rich German panel data set containing information about three generations. This allows instrumenting maternal education by the number of her siblings while conditioning on grandparental characteristics. The instrumental variables approach has not yet been used in the intergenerational context and works for the sample sizes of common household panels. We find substantial effects on hea...

    The Final Environmental Impact Statement (FEIS) for the Bonneville Power Administration (BPA) Expanded Residential Weatherization Program has been completed, printed, and distributed. This document incorporates numerous revisions based on both oral and written comments received during the public comment of the Draft Environmental Impact Statement (DEIS). The estimates of regional health effects were revised to incorporate results of the second Pacific Northwest Residential Energy Survey (PNWRES). The FEIS now expresses the estimated regional health effects in terms of incidence of cancers per 100,000 people exposed, which allows comparison to be made to the annual average risk of fatality by other causes. The estimates of regional health effects are also compared to health effects resulting from supplying and operating a conventional coal plant at a power level equal to the amount of energy saved from installation of additional tightening measures. Numerical results for the estimated health effects described above are provided. A summary of the comments received on the DEIS is also provided, along with estimated health effects associated with the Environmentally Preferred and BPA Preferred Alternatives to the Proposed Action. 8 refs., 3 figs., 5 tabs

    Phytoestrogens are plant-derived dietary compounds with structural similarity to 17-β-oestradiol (E2), the primary female sex hormone. This structural similarity to E2 enables phytoestrogens to cause (anti)oestrogenic effects by binding to the oestrogen receptors. The aim of the present review is to

  13. Health effects of low-level radiations

    1982-01-01

    Epidemiological surveys have attempted to assess the carcinogenic risk induced by exposure to low doses of ionizing radiation. Such studies are difficult to carry out because the incidence of radiation induced cancers is of only a few per cent, even following relativity large doses, and because there is no way to distinguish radiation induced cancer from the background of natural human cancers; moreover these surveys are exposed to many biases due to relatively small sizes of the populations studied and the difficulties of finding an appropriate control group, of estimating the absorbed doses and of collecting the data. A few national or international expert committees have analysed the available data and evaluated the carcinogenic effects. Their estimations of the risk, are similar and allow one to quantify the carcinogenic risk for doses above 100 rads. The risks of lower doses must be determined by extrapolation from human data at high doses. This extrapolation requires the knowledge of the dose-effect relationship. A linear extrapolation is most common and probably leads to a conservative estimate of the risk. A linear-quadratic function is probably more realistic and in better accordance with most scientific data. However the validity of its use for the estimation of carcinogenic risk is still debated. In experimental animals, the influence of dose-rate is important and some data suggest that this is the same for the carcinogenic effect in human beings. The genetic effects are probably less important than was feared a few years ago. The most important recent observation is the absence of any significant genetic effect in the progeny of the survivors of the A. bombs in Hiroshima and Nagasaki. This allows a conservative estimate of the maximum genetic risk for human beings [fr

    Hass avocados, the most common commercial avocado cultivars in the world, contain a variety of essential nutrients and important phytochemicals. Although the official avocado serving is one-fifth of a fruit (30 g), according to NHANES analysis the average consumption is one-half an avocado (68 g), which provides a nutrient and phytochemical dense food consisting of the following: dietary fiber (4.6 g), total sugar (0.2 g), potassium (345 mg), sodium (5.5 mg), magnesium (19.5 mg), vitamin A (43 μg), vitamin C (6.0 mg), vitamin E (1.3 mg), vitamin K1 (14 μg), folate (60 mg), vitamin B-6 (0.2 mg), niacin (1.3 mg), pantothenic acid (1.0 mg), riboflavin (0.1 mg), choline (10 mg), lutein/zeaxanthin (185 μg), phytosterols (57 mg), and high-monounsaturated fatty acids (6.7 g) and 114 kcals or 1.7 kcal/g. The avocado oil consists of 71% monounsaturated fatty acids (MUFA), 13% polyunsaturated fatty acids (PUFA), and 16% saturated fatty acids (SFA), which helps to promote healthy blood lipid profiles and enhance the bioavailability of fat soluble vitamins and phytochemicals from the avocado or other fruits and vegetables, naturally low in fat, which are consumed with avocados. There are eight preliminary clinical studies showing that avocado consumption helps support cardiovascular health. Exploratory studies suggest that avocados may support weight management and healthy aging. PMID:23638933

    Quantal health effects such as cancer, correlated with the combined action of three toxic agents, are considered. Data on the combined effects of two agents are scarce and no such data exist for three toxicants, yet concerns have arisen about simultaneous exposure of radiation workers to three different agents. Using models developed from the analysis of health effects involving two toxicants, equations for the combined effects of three agents are derived from a more general formalism. An application of practical interest is the incidence of cancer of the esophagus and its correlation with concurrent exposures to alcohol, tobacco, and either low- or high-LET radiation. (author)

  16. Effects of nuclear war on health and health services. 2. edition.

    1987-01-01

    In 1981 the World Health Assembly decided to establish an international committee of scientists and experts to study and report on the effects of nuclear war on health and health services. The first report, published in 1984, concluded that it was impossible to prepare health services to deal in any systematic way with a catastrophe resulting from nuclear warfare. This second report incorporates the results of new studies using modern analytical techniques. It focuses not only on the direct effects of nuclear conflict on human beings, but also on the environmental effects - on climate, agriculture and social and economic infrastructure, all of which would profoundly influence human life in both the short- and long-term. The psychological effects of living under the threat of nuclear war are also examined. The experts concluded that no health service anywhere in the world would be able to deal significantly with the appalling health consequences of nuclear war, especially since the health services themselves would be largely destroyed or incapacitated. In the circumstances the experts emphasized the importance of preventing a nuclear conflict. Refs, figs and tabs

    Volcanic eruptions are common in Iceland and have caused health problems ever since the settlement of Iceland. Here we describe volcanic activity and the effects of volcanic gases and ash on human health in Iceland. Volcanic gases expelled during eruptions can be highly toxic for humans if their concentrations are high, irritating the mucus membranes of the eyes and upper respiratory tract at lower concentrations. They can also be very irritating to the skin. Volcanic ash is also irritating for the mucus membranes of the eyes and upper respiratory tract. The smalles particles of volcanic ash can reach the alveoli of the lungs. Described are four examples of volcanic eruptions that have affected the health of Icelanders. The eruption of Laki volcanic fissure in 1783-1784 is the volcanic eruption that has caused the highest mortality and had the greatest effects on the well-being of Icelanders. Despite multiple volcanic eruptions during the last decades in Iceland mortality has been low and effects on human health have been limited, although studies on longterm effects are lacking. Studies on the effects of the Eyjafjallajökul eruption in 2010 on human health showed increased physical and mental symptoms, especially in those having respiratory disorders. The Directorate of Health in Iceland and other services have responded promptly to recurrent volcanic eruptions over the last few years and given detailed instructions on how to minimize the effects on the public health. Key words: volcanic eruptions, Iceland, volcanic ash, volcanic gases, health effects, mortality. Correspondence: Gunnar Guðmundsson, ggudmund@landspitali.is.

    Health promotion intervention in schools is a useful strategy to improve students' health awareness. The purpose of this study was to assess the effect of eye health promotion interventions on eye health literacy in school children in Vietnam. A piloted questionnaire was administered to 300 children from five secondary schools in Ba Ria-Vung Tau, Vietnam at baseline and re-administered after the eye health promotion interventions. McNemar chi-square and logistic regression were used for statistical analysis. A total of 300 children aged 12-15 years (mean, 13.3 ± 1.3 years; 60% female) participated in the baseline survey. The participation rate in the post-health promotion survey was 94.7%. After the health promotion interventions, number of children who had correct eye health knowledge increased by 10-20% (60-75% to 70-95%), more children reported having had an eye examination (63.3% to 84.7%; p promotion interventions significantly improve eye health knowledge, attitudes and practices of school children. Additionally, participation of parents and teachers as change agents may further improve children's health literacy. © The Author 2017. Published by Oxford University Press. All rights reserved.

    2012-01-01

    Reliable response measurements are extremely important for proper bridge health monitoring but incomplete and unreliable data may be acquired due to sensor problems and environmental effects. In the case of a sensor malfunction, parts of the measured data can be missing so that the structural health condition cannot be monitored reliably. This means that the dynamic characteristics of natural frequencies can change as if the structure is damaged due to environmental effects, such as temperature variations. To overcome these problems, this paper proposes a systematic procedure of data analysis to recover missing data and eliminate the environmental effects from the measured data. It also proposed a health index calculated statistically using revised data to evaluate the health condition of a bridge. The proposed method was examined using numerically simulated data with a truss structure and then applied to a set of field data measured from a cable stayed bridge

    Since the early 1970s, the health effects of indoor air pollution have been investigated with increasing intensity. Consequently, a large body of literature is now available on diverse aspects of indoor air pollution: sources, concentrations, health effects, engineering, and policy. This review begins with a review of the principal pollutants found in indoor environments and their sources. Subsequently, exposure to indoor air pollutants and health effects are considered, with an emphasis on those indoor air quality problems of greatest concern at present: passive exposure to tobacco smoke, nitrogen dioxide from gas-fueled cooking stoves, formaldehyde exposure, radon daughter exposure, and the diverse health problems encountered by workers in newer sealed office buildings. The review concludes by briefly addressing assessment of indoor air quality, control technology, research needs, and clinical implications. 243 references

    1996-12-31

    Air pollution epidemiology is the study of the occurrence and distribution of health outcomes in association with community air pollution exposure. It is therefore specific in the exposure variable. Air pollution health effects became evident during high air pollution episodes which occurred in the first decades of our century. Since then, legal and other control measures have led to lower air pollution levels. However, recent results from several studies indicate that lower levels of air pollution than the previously considered safe have serious adverse health effects. Although, there is increasingly agreement that air pollution, at levels measured today, affects health, there is still a lot to be understood concerning specific causal pollutants, biologic mechanisms involved and sensitive groups of individuals. The extent of potential confounding, time-considerations in air pollution effects, individual variation in air pollution exposure and exposure misclassification are some factors which complicate the study of these issues.

  4. Health effects of internally deposited radionuclides

    2008-01-01

    A comparative evaluation has been conducted of the ionizing radiation dose-response relationships in both human and laboratory animal studies involving internal deposition of radionuclides including alpha-emitters 226 Ra, 238 Pu, 239 Pu, and 241 Am and beta-emitters 90 Sr, 90 Y and 144 Ce. Intake routes included inhalation, injection, and ingestion. The preeminent importance of dose rate was revealed in this analysis. The lifetime effects of the ionizing radiation from internal emitters are described by three-dimensional dose rate/ time/response surfaces that compete with other causes of death during an individual's lifetime. Using maximum likelihood survival regression methods, the characteristic logarithmic slope for cancer induction was found to be about negative one-third for alpha-emitters or about negative two-thirds for beta-emitters. The relative biological effectiveness (RBE) of alpha versus beta radiations for cancer induction is a strong function of dose rate, near one at high dose rates and greater than 20 at low dose rates. The cumulative dose required to yield any level of induced-cancer risk is less at lower dose rates than at higher dose rates showing an apparent inverse-dose effect (up to a factor of 10 for high LET alpha radiation and a factor of 2 for low LET beta radiation). The competing risks of death associated with radiation injury, radiation-induced cancer, and natural aging are graphically shown using three-dimensional illustrations. At the higher average dose rates the principal deleterious effects are those associated with radiation-induced injury while at intermediate average dose rates radiation-induced cancer predominates. At the lower average dose rates the long latency time required for radiation-induced cancer may exceed natural life span, yielding an apparent lifespan effective threshold for death associated with radiation-induced cancer for cumulative doses to the target tissue below from 1.1 to 1.4 Gy for alpha-emitters or below

    This report is a revision of NUREG/CR-4214, Rev. 1, Part 1 (1990), Health Effects Models for Nuclear Power Plant Accident Consequence Analysis. This revision has been made to incorporate changes to the Health Effects Models recommended in two addenda to the NUREG/CR-4214, Rev. 1, Part 11, 1989 report. The first of these addenda provided recommended changes to the health effects models for low-LET radiations based on recent reports from UNSCEAR, ICRP and NAS/NRC (BEIR V). The second addendum presented changes needed to incorporate alpha-emitting radionuclides into the accident exposure source term. As in the earlier version of this report, models are provided for early and continuing effects, cancers and thyroid nodules, and genetic effects. Weibull dose-response functions are recommended for evaluating the risks of early and continuing health effects. Three potentially lethal early effects -- the hematopoietic, pulmonary, and gastrointestinal syndromes are considered. Linear and linear-quadratic models are recommended for estimating the risks of seven types of cancer in adults - leukemia, bone, lung, breast, gastrointestinal, thyroid, and ''other''. For most cancers, both incidence and mortality are addressed. Five classes of genetic diseases -- dominant, x-linked, aneuploidy, unbalanced translocations, and multifactorial diseases are also considered. Data are provided that should enable analysts to consider the timing and severity of each type of health risk

    Environmental influences on health and health behavior have an important place in research on worksite health promotion. We tested the validity and internal consistency of a new measure of organizational health and safety climate that was used in a large randomized trial of a worksite cancer prevention program (the Working Well Trial). The resulting scales then were applied to assess intervention effects. This study uses data from a subset of 40 worksites in the Working Well Trial. Employees at 20 natural gas pipeline worksite and 20 rural electrical cooperatives completed a cross-sectional questionnaire at baseline and 3-year follow-up. A factor analysis of this self-report instrument produced a two-factor solution. The resulting health and safety climate scales had good internal consistency (Cronbach's alpha = 0.74 and 0.82, respectively) and concurrent validity. The health climate scale was correlated more highly with organizational measures that were indicative of a supportive health climate than those indicating supportive safety climate, while the reverse was true of the safety climate scale. Changes in health climate were associated with the number of smoking and smokeless tobacco programs offered at the worksites at the time of the 3-year follow-up (r = 0.46 and 0.42, respectively). The scales were not correlated with most employee health behaviors. The health climate scores increased at intervention worksites, compared with scores at control worksites (F[1,36] = 7.57, P = 0.009). The health and safety climate scales developed for this study provide useful instruments for measuring organizational change related to worksite health promotion activities. The Working Well Intervention resulted in a significant improvement in worksite health climate.

    To systematically summarize the evidence for the effects of martial arts on health and fitness, to show the strengths of different types of martial arts, and to get a more complete picture of the impacts of martial arts on health, and also to provide a basis for future research on martial arts as an exercise prescription in exercise therapy. We searched for "martial arts"health" and "random" in eight databases (n= 5432). Randomized controlled trials and controlled clinical trials on the health effects of martial arts were included in the study. The final analysis included 28 papers (one general martial arts, one kung fu, sixteen tai chi, six judo, three karate, and one taekwondo). Among the disciplines of martial arts, tai chi was the most well-studied, followed by judo, karate, and taekwondo. Research topics varied widely, and included health, injuries, competition, morals and psychology, and herbal medicine. Most found positive effects on health. Tai chi is no-contact, low-impact, soft body and mindfulness exercise, which has been widely adopted by elderly people and proven to be a beneficial health promotion exercise. Research on judo, karate, and taekwondo mainly focused on improvements to athletes' competitive abilities, rather than on health effects. We did not find any published randomized controlled trials or controlled clinical trials on aikido, kendo, sumo, kyudo, qi gong, or other disciplines. Since martial arts are widely practiced, their effects on physiology, morphology, immunology, and neurology should be further studied in order to help people to select the best discipline or style to accomplish their purposes. This necessitates categorizing and classifying the disciplines and styles according to their effects on different body systems and levels of contact, as well as standardizing evaluation criteria for martial arts. Martial arts as an exercise prescription can then move from an experience-based to an evidence-based treatment. © 2010 Blackwell

    In Germany aprox. 15% of all employees have irregular or flexible working hours. Disturbed sleep and/or hypersomnia are direct consequences of shift work and therefore described as shift work disorder. Beyond this, shift work can also be associated with specific pathological disorders. There are individual differences in tolerance to shift work. Optimization of both shift schedules and sleep to "non-physiological" times of the day are measures to counteract the negative effects of shift work. There is still not enough evidence to recommend drugs for routine use in shift workers. © Georg Thieme Verlag Stuttgart · New York.

    Consideration is given to results of wide-scale examination of human population, subjected to the effect of radiation in result of Chernobyl accident. The examined contingents consisted of liquidators, evacuated from 30-km zone, people still living in contamination territories, children of irradiated parents and children, who received large radiation doses. High levels of respiratory system diseases, digestive system diseases, cardiovascular diseases and nervous system diseases were revealed for these people. It was revealed that stress, socio-economic and chemical factors played sufficient role in disease incidence. It is shown that fair of radiation may damage more, than radiation itself

    Background Non-medical professionals (consumers) are increasingly using the Internet to support their health information needs. However, the cognitive effort required to perform health information searches is affected by the consumer’s familiarity with health topics. Consumers may have different levels of familiarity with individual health topics. This variation in familiarity may cause misunderstandings because the information presented by search engines may not be understood correctly by the consumers. Objective As a first step toward the improvement of the health information search process, we aimed to examine the effects of health topic familiarity on health information search behaviors by identifying the common search activity patterns exhibited by groups of consumers with different levels of familiarity. Methods Each participant completed a health terminology familiarity questionnaire and health information search tasks. The responses to the familiarity questionnaire were used to grade the familiarity of participants with predefined health topics. The search task data were transcribed into a sequence of search activities using a coding scheme. A computational model was constructed from the sequence data using a Markov chain model to identify the common search patterns in each familiarity group. Results Forty participants were classified into L1 (not familiar), L2 (somewhat familiar), and L3 (familiar) groups based on their questionnaire responses. They had different levels of familiarity with four health topics. The video data obtained from all of the participants were transcribed into 4595 search activities (mean 28.7, SD 23.27 per session). The most frequent search activities and transitions in all the familiarity groups were related to evaluations of the relevancy of selected web pages in the retrieval results. However, the next most frequent transitions differed in each group and a chi-squared test confirmed this finding (Pinformation search patterns

    As part of a computer code system for nuclear reactor accident consequence analysis, two computer codes have been developed for estimating health effects expected to occur following an accident. Health effects models used in the codes are based on the models of NUREG/CR-4214 and are revised for the Japanese population on the basis of the data from the reassessment of the radiation dosimetry and information derived from epidemiological studies on atomic bomb survivors of Hiroshima and Nagasaki. The health effects models include early and continuing effects, late somatic effects and genetic effects. The values of some model parameters are revised for early mortality. The models are modified for predicting late somatic effects such as leukemia and various kinds of cancers. The models for genetic effects are the same as those of NUREG. In order to test the performance of one of these codes, it is applied to the U.S. and Japanese populations. This paper provides descriptions of health effects models used in the two codes and gives comparisons of the mortality risks from each type of cancer for the two populations. (author)

    In 2003, the Turkish government introduced major health system changes, the Health Transformation Programme (HTP), to achieve universal health coverage (UHC). The HTP leveraged changes in all parts of the health system, organization, financing, resource management and service delivery, with a new family medicine model introducing primary care at the heart of the system. This article examines the effect of these health system changes on user satisfaction, a key goal of a responsive health system. Utilizing the results of a nationally representative yearly survey introduced at the baseline of the health system transformation, multivariate logistic regression analysis is used to examine the yearly effect on satisfaction with health services. During the 9-year period analyzed (2004-2012), there was a nearly 20% rise in reported health service use, coinciding with increased access, measured by insurance coverage. Controlling for factors known to contribute to user satisfaction in the literature, there is a significant (P < 0.001) increase in user satisfaction with health services in almost every year (bar 2006) from the baseline measure, with the odds of being satisfied with health services in 2012, 2.56 (95% confidence interval (CI) of 2.01-3.24) times that in 2004, having peaked at 3.58 (95% CI 2.82-4.55) times the baseline odds in 2011. Additionally, those who used public primary care services were slightly, but significantly (P < 0.05) more satisfied than those who used any other services, and increasingly patients are choosing primary care services rather than secondary care services as the provider of first contact. A number of quality indicators can probably help account for the increased satisfaction with public primary care services, and the increase in seeking first-contact with these providers. The implementation of primary care focused UHC as part of the HTP has improved user satisfaction in Turkey.

    Although reductions in lead (Pb) exposure for the U.S. population have resulted in lower blood Pb levels over time, epidemiological studies continue to provide evidence of health effects at lower and lower blood Pb levels. Low-level Pb was selected for evaluation by the National Toxicology Program (NTP) because of (1) the availability of a large number of epidemiological studies of Pb, (2) a nomination by the National Institute for Occupational Safety and Health for an assessment of Pb at lower levels of exposure, and (3) public concern for effects of Pb in children and adults. This evaluation summarizes the evidence in humans and presents conclusions on health effects in children and adults associated with low-level Pb exposure as indicated by less than 10 micrograms of Pb per deciliter of blood (Monograph on Health Effects of Low-Level Lead. The document and appendices are available at http://ntp.niehs.nih.gov/go/evals. This document provides background on Pb exposure and includes a review of the primary epidemiological literature for evidence that low-level Pb is associated with neurological, immunological, cardiovascular, renal, and/or reproductive and developmental effects. The NTP Monograph presents specific conclusions for each health effect area. Overall, the NTP concludes that there is sufficient evidence that blood Pb levels Monograph on November 17-18, 2011 (http://ntp.niehs.nih.gov/go/37090.

    Despite their prevalence in the environment, and the myriad studies that have shown associations between morbidity or mortality with proximity to roadways (proxy for motor vehicle exposures), relatively little is known about the toxicity of gasoline engine emissions (GEE). We review the studies conducted on GEE to date, and summarize the findings from each of these studies. While there have been several studies, most of the studies were conducted prior to 1980 and thus were not conducted with contemporary engines, fuels, and driving cycles. In addition, many of the biological assays conducted during those studies did not include many of the assays that are conducted on contemporary inhalation exposures to air pollutants, including cardiovascular responses and others. None of the exposures from these earlier studies were characterized at the level of detail that would be considered adequate today. A recent GEE study was conducted as part of the National Environmental Respiratory Center (www.nercenter.org). In this study several in-use mid-mileage General Motors (Chevrolet S-10) vehicles were purchased and utilized for inhalation exposures. An exposure protocol was developed where engines were operated with a repeating California Unified Driving Cycle with one cold start per day. Two separate engines were used to provide two cold starts over a 6-h inhalation period. The exposure atmospheres were characterized in detail, including detailed chemical and physical analysis of the gas, vapor, and particle phase. Multiple rodent biological models were studied, including general toxicity and inflammation (e.g., serum chemistry, lung lavage cell counts/differentials, cytokine/chemokine analysis, histopathology), asthma (adult and in utero exposures with pulmonary function and biochemical analysis), cardiovascular effects (biochemical and electrocardiograph changes in susceptible rodent models), and susceptibility to infection (Pseudomonas bacteria challenge).

    very low for all evaluated samples (less than 20% after 10 days of equilibrium), being the best performance one, the nitosoil sample whose K{sub d} values varied from 11.78 to 63.05 mL.g{sup -1}. In a subsequent step, the clay soil, was submitted to the alkaline solution interaction, in order to investigate possible alterations on the sorption properties and hydraulic conductivity of this soil. Using the sorption parameters, obtained from data fitted isotherms, the retardation factor, R, was estimated for the samples before and after the interaction. It was demonstrated that the alkaline alteration promotes damages to sorption properties of Cs, once the R became significantly smaller (about 1000 times) after the interaction. The hydraulic conductivity in turn increased slightly (3,91x10{sup -8} cm.s{sup -1} to 5,08 x 10{sup -8} cm.s{sup -1}). It was concluded that these changes were due, mainly, to the dissolution of minerals present in the clay soil (kaolinite and quartz), associated with the incorporation of K and Ca from the alkaline solution, resulting, probably, in the formation of hydrated calcium silicate phases. Additionally, the effects of alkaline solution on the properties of a commercial bentonite were studied. Contrary to the clay soil, it was observed a gain in the sorption characteristics, with K{sub d} (Cs) increasing from 760.05 mL.g{sup -1}to 1311.80 mL.g{sup -1}and Q{sub max} from 36.32 mg.g{sup -1}to 52.13 mg.g{sup -1}, with the corresponding increase in the retardation coefficient, R. The dissolution of the clay minerals from the initial sample and the incorporation of Mg, K e Ca coming from the alkaline solution, generating smectite of different kinds, were considered as the main mineralogical changes responsible for the modifications in sorption parameters. The different behavior between the two evaluated samples, soil and bentonite, confirms that the nature and extension of changes observed, when mineral samples interact with alkaline solution

  20. Categories of adverse health effects from indoor air pollution

    There is a lack of precision in the definition of health, which leads to confusion in the assessment of adverse effects arising from indoor air pollution. Adverse health effects range from annoyance to life-threatening conditions. Survey responses suggest that males and females differ in their perception of a healthy person, but both sexes envisage a male in terms of positive fitness, strength, energy and the possession of an athletic body, rather than how long one was likely to live. Psychological fitness was relatively unimportant in describing the health of others, but was rates as very important with respect to one's own health. Mortality statistics tend to obscure the proportion of the population who suffer chronic illness that is not life threatening. Although health is largely determined by genetic constitution, lifestyle and environmental factors, the morale of an individual is also important. A new classification of the adverse effects on health of indoor air pollution is proposed: this includes 'comfort' responses, such as sick building syndrome (category 1); acute chemical effects, the nature of which depends upon the specific intoxicant (category 2B), and perceived chronic grave risk, including cancer causation (category 3). The magnitude of risk in this latter category is imprecise, because its measurement involves the technique of quantitative risk assessment. (author) 1 fig., 2 tabs., 158 refs

    Earthquakes are natural disasters that can occur at any time, regardless of the location. Their frequency is higher in the Circum-Pacific and Mediterranean/Trans-Asian seismic belt. A number of sophisticated methods define their magnitude using the Richter scale and intensity using the Mercani-Cancani-Sieberg scale. Recorded data show a number of devastating earthquakes that have killed many people and changed the environment dramatically. Croatia is located in a seismically active area, which has endured a series of historical earthquakes, among which several occurred in the Zagreb area. The consequences of an earthquake depend mostly on the population density and seismic resistance of buildings in the affected area. Environmental consequences often include air, water, and soil pollution. The effects of this kind of pollution can have long-term health effects. The most dramatic health consequences result from the demolition of buildings. Therefore, quick and efficient aid depends on well-organized health professionals as well as on the readiness of the civil defence, fire department, and Mountain Rescue Service members. Good coordination among these services can save many lives Public health interventions must include effective control measures in the environment as secondary prevention methods for health problems caused by unfavourable environmental factors. The identification and control of long-term hazards can reduce chronic health effects. The reduction of earthquake-induced damages includes setting priorities in building seismically safe buildings.

    The U.S. health care sector is highly interconnected with industrial activities that emit much of the nation's pollution to air, water, and soils. We estimate emissions directly and indirectly attributable to the health care sector, and potential harmful effects on public health. Negative environmental and public health outcomes were estimated through economic input-output life cycle assessment (EIOLCA) modeling using National Health Expenditures (NHE) for the decade 2003-2013 and compared to national totals. In 2013, the health care sector was also responsible for significant fractions of national air pollution emissions and impacts, including acid rain (12%), greenhouse gas emissions (10%), smog formation (10%) criteria air pollutants (9%), stratospheric ozone depletion (1%), and carcinogenic and non-carcinogenic air toxics (1-2%). The largest contributors to impacts are discussed from both the supply side (EIOLCA economic sectors) and demand side (NHE categories), as are trends over the study period. Health damages from these pollutants are estimated at 470,000 DALYs lost from pollution-related disease, or 405,000 DALYs when adjusted for recent shifts in power generation sector emissions. These indirect health burdens are commensurate with the 44,000-98,000 people who die in hospitals each year in the U.S. as a result of preventable medical errors, but are currently not attributed to our health system. Concerted efforts to improve environmental performance of health care could reduce expenditures directly through waste reduction and energy savings, and indirectly through reducing pollution burden on public health, and ought to be included in efforts to improve health care quality and safety.

    Full Text Available Abstract Background Despite the expanding literature on how reforms may affect health workers and which reactions they may provoke, little research has been conducted on the mechanisms of effect through which health sector reforms either promote or discourage health worker performance. This paper seeks to trace these mechanisms and examines the contextual framework of reform objectives in Uganda and Bangladesh, and health workers' responses to the changes in their working environments by taking a 'realistic evaluation' approach. Methods The study findings were generated by triangulating both qualitative and quantitative methods of data collection and analysis among policy technocrats, health managers and groups of health providers. Quantitative surveys were conducted with over 700 individual health workers in both Bangladesh and Uganda and supplemented with qualitative data obtained from focus group discussions and key interviews with professional cadres, health managers and key institutions involved in the design, implementation and evaluation of the reforms of interest. Results The reforms in both countries affected the workforce through various mechanisms. In Bangladesh, the effects of the unification efforts resulted in a power struggle and general mistrust between the two former workforce tracts, family planning and health. However positive effects of the reforms were felt regarding the changes in payment schemes. Ugandan findings show how the workforce responded to a strong and rapidly implemented system of decentralisation where the power of new local authorities was influenced by resource constraints and nepotism in recruitment. On the other hand, closer ties to local authorities provided the opportunity to gain insight into the operational constraints originating from higher levels that health staff were dealing with. Conclusion Findings from the study suggest that a reform planners should use the proposed dynamic responses model to

  6. The Health Effects of Income Inequality: Averages and Disparities.

    Much research has investigated the association of income inequality with average life expectancy, usually finding negative correlations that are not very robust. A smaller body of work has investigated socioeconomic disparities in life expectancy, which have widened in many countries since 1980. These two lines of work should be seen as complementary because changes in average life expectancy are unlikely to affect all socioeconomic groups equally. Although most theories imply long and variable lags between changes in income inequality and changes in health, empirical evidence is confined largely to short-term effects. Rising income inequality can affect individuals in two ways. Direct effects change individuals' own income. Indirect effects change other people's income, which can then change a society's politics, customs, and ideals, altering the behavior even of those whose own income remains unchanged. Indirect effects can thus change both average health and the slope of the relationship between individual income and health.

    For over two decades, cannabis, commonly known as marijuana, has been the most widely used illicit drug by young people in high-income countries, and has recently become popular on a global scale. Epidemiological research during the past 10 years suggests that regular use of cannabis during adolescence and into adulthood can have adverse effects. Epidemiological, clinical, and laboratory studies have established an association between cannabis use and adverse outcomes. We focus on adverse health effects of greatest potential public health interest-that is, those that are most likely to occur and to affect a large number of cannabis users. The most probable adverse effects include a dependence syndrome, increased risk of motor vehicle crashes, impaired respiratory function, cardiovascular disease, and adverse effects of regular use on adolescent psychosocial development and mental health.

    Although the health effects of radiation doses in occupationally exposed persons had received attention, it was not until the 1950s, when the atmospheric atom bomb tests of the United States and the Soviet Union had raised the level of environmental radioactivity, that the long-term effects of low-level radiation dosage became a matter of popular concern throughout the world. The United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) was created, and the World Health Organization (WHO) appointed an expert committee to provide advice concerning radiation and human health. In its first report, the WHO expert committee identified several areas of high natural radiation where studies of the exposed population might possibly provide information concerning the effects of chromic low-level radiation dosage

    The aim of the study was to develop and test a routine evaluation system for all health promotion and education activities funded by the German statutory health insurance companies. The system aims at measuring both individual health effects and the complex organisational effects of setting projects. Measurement instruments were developed synoptically and tested in three field tests (2003-2008). In order to assess the impact of individual health training, 212 courses of the health insurance companies were evaluated. To assess the setting approach, 56 schools participating in a health-promotion project were included, and for workplace health-promotion 6 projects of different health insurance companies were included. The research design was an observational study. Instead of control groups, individual data were compared to reference values for gender- and age-matched groups from national health surveys. The studies consisted of baseline and final assessment (T1/T2), complemented by a follow-up (T3), all adapted to the time of intervention (i. e., 3-24 months for T1/T2 and 3-18 months for T2/T3). The evaluation system provides multilevel-measurement based upon validated questionnaires for health-related structures and processes in institutions, and for the participating individual's subjective health, health problems, health-related quality of life, workplace and institutional satisfaction. Controlling for central confounders is also possible (input and dosage, age, gender, educational background). Thus, short but valid measurement instruments of high usability are available to evaluate the effectiveness of prevention, health promotion and education. © Georg Thieme Verlag KG Stuttgart · New York.

    This article explores the effects of the 2010 Haiti earthquake on women's reproductive health, using geocoded data from the 2005 and 2012 Haiti Demographic and Health Surveys. We use geographic variation in the destructiveness of the earthquake to conduct a difference-in-difference analysis. Results indicate that heightened earthquake intensity reduced use of injectables-the most widely used modern contraceptive method in Haiti-and increased current pregnancy and current unwanted pregnancy. Analysis of impact pathways suggests that severe earthquake intensity significantly increased women's unmet need for family planning and reduced their access to condoms. The earthquake also affected other factors that influence reproductive health, including women's ability to negotiate condom use in their partnerships. Our findings highlight how disruptions to health care services following a natural disaster can have negative consequences for women's reproductive health. © 2016 The Population Council, Inc.

    Full Text Available Terrorism is a disruptive man-made disaster event challenging human health and wellbeing. It is a hostile activity which brings about much casualty, even death. It not only causes physical casualties but also brings about psychological morbidity and can lead to long term mental disorders. The effects of terrorist attacks on people’s psychological health covers a wide range such as acute stress symptoms to long term disorders like Post-traumatic Stress Disorder (PTSD. The psychological disorder due to traumatic distress is treated with psychotherapies such as psychosocial intervention, psychological debriefing, psychological first aid care, psychological counseling services, and psychoeducation. Government is supporting state and local public health departments to develop efficient public health preparedness planning programs in case of emergency situations. There are some newer approaches working towards enhancing health security and managing responses to a psychological impact of a disaster event like a terrorist attack.

    1984-01-01

    Possible health problems created by high natural levels of background radiation are hard to detect, partly because the health problems involved would exist to some degree irrespective of radiation exposure, partly because other factors affect the incidence of such problems, and partly because the differences between normal background radiation levels and radiation levels found in most high-radiation areas are not extreme. Nevertheless, the need to know about such health effects is evident, and so various studies conducted over the past 30 years have sought to determine whether those effects exist and what they are. Overall, however, the fragmentary and uncertain nature of many of these findings makes it hard to draw firm conclusions about the health risks involved or the desirability of countermeasures. So despite considerable efforts and some progress over the past three decades, the need for a clear quantitative assessment of the consequences is as great as ever

    To examine the effect of perceived health status on three components of patient satisfaction. The Household Component of the 1999 Medical Expenditure Panel Survey for people 35-64 years of age was used to examine the effect of perceived health status on patient satisfaction measured in terms of access to care, provider quality and quality of care. Descriptive statistics and multivariate regression were used to describe the subjects and to examine the relationship between patient satisfaction and perceived health status controlling for patient demographic factors, health factors and provider characteristics. All analyses used STATA 8.0 which is designed to analyze weighted data. A total of 4,417 patients (71% women) met the inclusion criteria for the study. Patients who rated their health excellent or good scored higher on the three dimensions of patient satisfaction. Higher scores on one or more components of patient satisfaction were associated with being older, married, better educated and having higher income, health insurance and good mental health. Seeing the health-care provider for an old problem resulted in lower levels of patient satisfaction. Provider characteristics significantly related to patient satisfaction were listening to the patient, being a specialist, seeing patients in an office setting and being located in the South. This study has shown that patient satisfaction is influenced by a person's self-perceived health status and other personal characteristics that are external to the delivery of health care. These findings suggest that patient satisfaction data should be used judiciously because a significant portion of the variation may be attributed to factors endogenous to the patient and therefore are not amenable to provider intervention.

    In this review, we address significant characteristics of parturition in the pig and their connection to post-partum reproductive health and fertility. We discuss the normal physiology and behaviour around parturition and the effect of the second phase (expulsion of foetuses) on the third phase of parturition (expulsion of foetal membranes). In addition, we intend to cover retained placenta, and the connection to post-partum uterine health and fertility in the contemporary prolific sow. We al...

    This paper investigates whether cannabis use affects physical and mental health. To do so, information on prime aged individuals living in Amsterdam in 1994 is used. Dutch data offer a clear advantage in estimating the health impacts of cannabis use because the legal status of cannabis in the Netherlands ensures that estimates are free from confounding with the physical and psychological effects of engaging in a criminal activity. Accounting for selection into cannabis use and shared frailtie...

    1997-10-18

    Reduction of personnel by businesses and other organisations (organisational downsizing) is common in Europe, but little is known about its effects on the health of employees. We used employers' records to investigate the relation between downsizing and subsequent absenteeism because of ill health in 981 local-government workers who remained in employment in Raisio, south-western Finland, during a period of economic decline (1991-95). Data were separated into three time periods: 1991, before downsizing; 1993, major downsizing in some workplaces and occupations; and 1993-95, after downsizing. We obtained data on sick leave from records kept by the occupational health-care unit in Raisio. We also investigated whether the effects of downsizing were dependent on ten other predictors of sick leave. There was a significant association between downsizing and medically certified sick leave. The rate of absenteeism was 2.3 times greater (95% CI 2.0-2.7) after major downsizing, classified by occupation, than after minor downsizing. The corresponding rate ratios for musculoskeletal disorders and trauma were 5.7 (4.1-8.0) and 2.7 (1.7-4.2), respectively. The effects of downsizing by workplace depended on the age distribution of the staff. When the proportion of employees who were older than 50 years was high, downsizing increased the individual risk of absence because of ill health by 3.2-14.0 times, depending on diagnostic category. When the proportion of employees over 50 years was low, downsizing had only slight effects on health. Other risk factors that increased rates of sick leave after downsizing were age over 44 years, a large workplace, poor health before downsizing, and high income. Downsizing is a risk to the health of employees. But this risk varies according to individual factors, such as age, socioeconomic status, and health, as well as factors related to place of work, for example, size and age structure of the staff.

  2. State Support: A Prerequisite for Global Health Network Effectiveness

    2018-01-01

    Shiffman recently summarized lessons for network effectiveness from an impressive collection of case-studies. However, in common with most global health governance analysis in recent years, Shiffman underplays the important role of states in these global networks. As the body which decides and signs international agreements, often provides the resourcing, and is responsible for implementing initiatives all contributing to the prioritization of certain issues over others, state recognition and support is a prerequisite to enabling and determining global health networks’ success. The role of states deserves greater attention, analysis and consideration. We reflect upon the underappreciated role of the state within the current discourse on global health. We present the tobacco case study to illustrate the decisive role of states in determining progress for global health networks, and highlight how states use a legitimacy loop to gain legitimacy from and provide legitimacy to global health networks. Moving forward in assessing global health networks’ effectiveness, further investigating state support as a determinant of success will be critical. Understanding how global health networks and states interact and evolve to shape and support their respective interests should be a focus for future research. PMID:29524958

    The purpose of this study was to examine the communication dynamics leading to the adoption of new attitudes and cognitions in health education sessions. We examined the verbal interactions at work in persuasive communication in 16 health education sessions. The study found that the medical expertise of the educator and the initial level of commitment of the participants had a positive effect on adherence to recommendations. However, persuasive communication in health education sessions appears to involve a paradoxical process in which criticism of the message can go hand in hand with the expression of an intention to implement new risk-reducing behaviors.

    The earth's climate is changing and increasing ambient heat levels are emerging in large areas of the world. An important cause of this change is the anthropogenic emission of greenhouse gases. Climate changes have a variety of negative effects on health, including cardiac health. People with pre-existing medical conditions such as cardiovascular disease (including heart failure), people carrying out physically demanding work and the elderly are particularly vulnerable. This review evaluates the evidence base for the cardiac health consequences of climate conditions, with particular reference to increasing heat exposure, and it also explores the potential further implications. © 2015 S.

    This study was designed to determine the effect of Quran listening without its musical tone (Tartil) on the mental health of personnel in Zahedan University of Medical Sciences, southeast of Iran. The results showed significant differences between the test and control groups in their mean mental health scores after Quran listening (P = 0.037). No significant gender differences in the test group before and after intervention were found (P = 0.806). These results suggest that Quran listening could be recommended by psychologists for improving mental health and achieving greater calm.

    Full Text Available Public health is a top priority for the European Union. The main factor in ensuring population health is food consumption and in particular food quality. The present paper aims at analyzing Romanian population food consumption during the 1990-2012 periods, its evolution in time; it identifies its main features and their effects on population health. Amid the economic crisis the purchasing power of population is impaired leading to insufficient consumption of fresh fruits and vegetables and a low intake of vitamins, calcium, phosphorous and iron (especially in children, women and elderly people, which could be an important risk factor in the development of chronic diseases.

    Full Text Available Abstract At a crossroads, global public health surveillance exists in a fragmented state. Slow to detect, register, confirm, and analyze cases of public health significance, provide feedback, and communicate timely and useful information to stakeholders, global surveillance is neither maximally effective nor optimally efficient. Stakeholders lack a globa surveillance consensus policy and strategy; officials face inadequate training and scarce resources. Three movements now set the stage for transformation of surveillance: 1 adoption by Member States of the World Health Organization (WHO of the revised International Health Regulations (IHR[2005]; 2 maturation of information sciences and the penetration of information technologies to distal parts of the globe; and 3 consensus that the security and public health communities have overlapping interests and a mutual benefit in supporting public health functions. For these to enhance surveillance competencies, eight prerequisites should be in place: politics, policies, priorities, perspectives, procedures, practices, preparation, and payers. To achieve comprehensive, global surveillance, disparities in technical, logistic, governance, and financial capacities must be addressed. Challenges to closing these gaps include the lack of trust and transparency; perceived benefit at various levels; global governance to address data power and control; and specified financial support from globa partners. We propose an end-state perspective for comprehensive, effective and efficient global, multiple-hazard public health surveillance and describe a way forward to achieve it. This end-state is universal, global access to interoperable public health information when it’s needed, where it’s needed.

    2017-09-01

    Ensuring an equitable health financing system is a major concern particularly in many developing countries. Internationally, there is a strong debate to move away from excessive reliance on direct out-of-pocket (OOP) spending towards a system that incorporates a greater element of risk pooling and thus affords greater protection for the poor. This is a major focus of the move towards universal health coverage (UHC). Currently, Zambia with high levels of poverty and income inequality is implementing health sector reforms for UHC through a social health insurance scheme. However, the way to identify the health financing mechanisms that are best suited to achieving this goal is to conduct empirical analysis and consider international evidence on funding universal health systems. This study assesses, for the first time, the progressivity of health financing and how it impacts on income inequality in Zambia. Three broad health financing mechanisms (general tax, a health levy and OOP spending) were considered. Data come from the 2010 nationally representative Zambian Living Conditions and Monitoring Survey with a sample size of 19,397 households. Applying standard methodologies, the findings show that total health financing in Zambia is progressive. It also leads to a statistically significant reduction in income inequality (i.e. a pro-poor redistributive effect estimated at 0.0110 (p taxes (0.0101 (p taxes. This points to areas where government policy may focus in attempting to reduce the high level of income inequality and to improve equity in health financing towards UHC in Zambia.

    2017-11-01

    Recent house price variation has strongly affected households' housing wealth and debt, yet the non-economic consequences of these changes in housing wealth are still poorly understood. Using a sample of 19,000 individuals from the Household, Income and Labour Dynamics in Australia Survey (HILDA) for 2001-2015, we examine the relationship between house price fluctuations and individual health by exploiting large exogenous changes in house prices in Australia. We find that an increase in local house prices is associated with a positive effect on the physical health of outright owners and a negative effect on the physical and mental health of renters. Improvements in physical health for outright owners can be partially attributed to health-related investments and behaviours such as a reduction in weight, an increase in physical exercise and an increase in time allocated to home production. These findings support the presence of a health-wealth gradient through the wealth mechanism distinct from the effects of local area amenities and macroeconomic conditions. Our findings highlight some of the often-overlooked social impacts - both positive and negative - of fluctuations in the housing market. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Polyphenols are a group of plant metabolites with potent antioxidant properties, which protect against various chronic diseases induced by oxidative stress. Evidence showed that dietary polyphenols have emerged as one of the prominent scientific interests due to their role in the prevention of degenerative diseases in humans. Possible health beneficial effects of polyphenols are measured based on the human consumption and their bioavailability. Lentil ( Lens culinaris ; Family: Fabaceae) is a great source of polyphenol compounds with various health-promoting properties. Polyphenol-rich lentils have a potential effect on human health, possessing properties such as antioxidant, antidiabetic, anti-obesity, anti-hyperlipidemic, anti-inflammatory and anticancer. Based on the explorative study, the current comprehensive review aims to give up-to-date information on nutritive compositions, bioactive compounds and the health-promoting effect of polyphenol-rich lentils, which explores their therapeutic values for future clinical studies. All data of in vitro , in vivo and clinical studies of lentils and their impact on human health were collected from a library database and electronic search (Science Direct, PubMed and Google Scholar). Health-promoting information was gathered and orchestrated in the suitable place in the review.

A one-year integrated health management intervention was applied in the health management groups. The physical indicators and metabolic indicators changed after one-year intervention on the overweight and obese adults. The annual reduction of the physical indicators was significant in all groups (p<0.05 except the weight loss in the placebo + general management group. The health management and the dietary supplement have statistically significant (p<0.001, p<0.001 effects on the annual reduction of these indicators and interactive effect between them was found on some of these indicators such as bodyweight, body mass index (BMI, body fat ratio (BFR, and hipline (p<0.05. The dietary supplement + health management group had the best annual reduction effects for the indicators among the groups. Integrated health management interventions including both dietary supplements intervention and health management could improve metabolic indicators in overweight and obese adults together with the physical indicators, suggesting the intermediated role of metabolic indictors in controlling obesity.

    Introduction: Violence against women is one of the major public health and human rights problem in the world today. Hence, the present study was conducted with the aim to assess the effect of domestic violence on oral health behavior and oral health status of females attending community outreach programmes in and around Modinagar. Materials and Methods: A cross-sectional study was conducted through the community outreach programmes organized in Modinagar. A structured questionnaire was used to illicit information regarding socio demographic characteristics, oral health behavior and domestic violence. The dental health examination was done to record dental health status, intraoral and extraoral soft tissue injury, tooth fracture and tooth avulsion due to the injury. Results: Out of the total 304 women, 204(67.1%) reported positive domestic violence. Psychological violence was found to be severe whereas sexual violence was found to be mild in most of the cases. Significant difference was found between oral hygiene aids used , frequency of tooth brushing, periodontal status, missing teeth, intraoral soft tissue injuries and fractures between both the groups (p<0.05). Conclusion: The present study confirmed that domestic violence had significant influence on oral health behavior and oral health status of women. Thus, the dental professionals also should make an attempt to help victims gain access to support and referral services and to provide adequate treatment to them so as to make a positive difference in their lives.

    Tea is one of the most consumed beverages in the world. Considerable studies show the exceptional health benefits (e.g. antioxidation, cancer prevention) of tea owing to its various bioactive components. However, data from these extensively published papers had not been made available in a central database. To lay a foundation in improving the understanding of healthy tea functions, we established a TBC2health database that currently documents 1338 relationships between 497 tea bioactive compounds and 206 diseases (or phenotypes) manually culled from over 300 published articles. Each entry in TBC2health contains comprehensive information about a bioactive relationship that can be accessed in three aspects: (i) compound information, (ii) disease (or phenotype) information and (iii) evidence and reference. Using the curated bioactive relationships, a bipartite network was reconstructed and the corresponding network (or sub-network) visualization and topological analyses are provided for users. This database has a user-friendly interface for entry browse, search and download. In addition, TBC2health provides a submission page and several useful tools (e.g. BLAST, molecular docking) to facilitate use of the database. Consequently, TBC2health can serve as a valuable bioinformatics platform for the exploration of beneficial effects of tea on human health.

    2010-01-01

    The attribution of health effects to prolonged radiation exposure situations, such as those experienced in nature, is a challenging problem. The paper describes the epistemological limitations for such attribution it demonstrate that in most natural exposure situations, the theory of radiation-related sciences is not capable to provide the scientific evidence that health effects actually occur (or do not occur) and, therefore, that radiation effects are attributable to natural exposure situations and imputable to nature. Radiation exposure at high levels is known to provoke health effects as tissue reactions. If individuals experience these effects they can be attributed to the specific exposure with a high degree of confidence under the following conditions: the dose incurred have been higher that the relevant dose-threshold for the specific effect; and an unequivocal pathological diagnosis is attainable ensuring that possible competing causes have been eliminated. Only under these conditions, the occurrence of the effect may be properly attested and attributed to the exposure. However, even high levels of natural radiation exposure are lower than relevant dose-thresholds for tissue reactions and, therefore, natural radiation exposure is generally unable to cause these type of effects. One exception to this general rule could be situations of high levels of natural radiation exposure that might be sufficient to induce opacities in the lens of the eyes (which could be considered a tissue-reaction type of effect)

    Alsunni, Ahmed Abdulrahman

    2015-10-01

    Consumption of energy drinks has been increasing dramatically in the last two decades, particularly amongst adolescents and young adults. Energy drinks are aggressively marketed with the claim that these products give an energy boost to improve physical and cognitive performance. However, studies supporting these claims are limited. In fact, several adverse health effects have been related to energy drink; this has raised the question of whether these beverages are safe. This review was carried out to identify and discuss the published articles that examined the beneficial and adverse health effects related to energy drink. It is concluded that although energy drink may have beneficial effects on physical performance, these products also have possible detrimental health consequences. Marketing of energy drinks should be limited or forbidden until independent research confirms their safety, particularly among adolescents.

  1. THE USE OF FLUORIDE AND ITS EFFECT ON HEALTH

    Full Text Available Appropriate oral health care is fundamental for any individual’s health. Dental caries is still one of the major public health problems. The most effective way of caries prevention is the use of fluoride. Fluoride occurs naturally in our environment and is always present in our lives. However, the concentration differs from area to area. Exposure can occur through diet, respiration and fluoride supplements. During pregnancy, the placenta acts as a barrier. The fluoride, therefore, crosses the placenta in low concentrations. Drinking water in Slovenia is not fluoridated; the amount of naturally present fluoride is very low. Fluoride can be toxic in extremely high concentrations. The most important effect of fluoride on caries incidence is through its role in the process of remineralisation and demineralisation of tooth enamel. The European Academy of Paediatric Dentistry (EAPD recommends a preventive topical use of fluoride supplements because of their cariostatic effect

    The Office of Health and Environmental Research (OHER) of the Department of Energy supports a broad long-term research program on human health and environmental effects from potential exposure to energy-related complex chemical mixtures. The program seeks basic mechanistic data on the effects of complex mixtures at the cellular, molecular, and whole animal levels to aid in predicting human health effects and seeks ecological data on biological and physical transformations in the mixtures, concentrations of the mixtures in various compartments of the environment, and potential routes for human exposure to these mixtures (e.g., food chain). On June 17-18, 1985, OHER held its First Annual Technical Meeting on the Complex Chemical Mixtures Program in Chicago, IL. The primary purpose of the meeting was to enable principal investigators to report the research status and accomplishments of ongoing complex chemical mixture studies supported by OHER. To help focus future research directions round table discussions were conducted.

    Cost-benefit is required for improving air quality efficiently. Benefit in connection with air quality has influence on health effects, a barrier to administration, aesthetic value, and material loss. Among these, health effects are occupying most of them. In this study, the economic value by the people in Seoul was estimated about symptoms of eye irritation, heartburn, and asthma among health effects relating to air pollution by using conditional value measurement (CVM). As a result, 2,580 won/day for eye irritation, 9,000 won/day for heartburn, and 55,400 won/day for asthma were measured. Moreover, in the case of carrying out several CV questions in one survey, it was found out that the estimated results of single variation model and dual variation model were different.

    Polychlorinated-biphenyls (PCBs) were introduced in the late 1920s and used until the 1970s when they were banned in most countries due to evidence of environmental build-up and possible adverse health effects. However they still persist in the environment, indoors and in humans. Indoor air...... in contaminated buildings may confer airborne exposure markedly above background regional PCB levels. To date, no epidemiological studies have assessed the health effects from exposure to semi-volatile PCBs in the indoor environment. Indoor air PCBs are generally less chlorinated than PCBs that are absorbed via...... the diet, or via past occupational exposure; therefore their health effects require separate risk assessment. Two separate cohorts of individuals who have either attended schools (n = 66,769; 26% exposed) or lived in apartment buildings (n = 37,185; 19% exposed), where indoor air PCB concentrations have...

    Increases of development and use of equipment that procedures non-ionizing radiant energy such as laser, radar, microwave ovens, power lines and hand phones, bring about public concern about the possible health effects owing to the non-ionizing radiation exposure. Non ionizing electromagnetic radiation compared to ionizing radiation, has longer wavelength, lower frequency, and lower photon energy in its interaction with body tissues. The term on non-ionizing radiation refers to the groups of electromagnetic radiations with energies less than about 10 eV corresponding to wavelengths in the ultraviolet, visible, infra red microwave and radiofrequency spectral regions. This paper describes the current state of knowledge about types of non-ionizing radiation and the health effects at molecular and cellular levels as well as its effects on human health. (author)

    Full Text Available Vibration was defined that oscillation of the body according to the reference point. The tools that are used in industry and are the source of vibration cause diseases. For this reason, the vibration has been one of the factors that affect the health and of the most widely researched in the field of ergonomics. The perceived intensity and health effects of vibration depend on the vibration frequency, intensity, direction, acceleration, duration of exposure, vibration affects the region, age, gender, posture, distance from the source person, activity, time of day and the person\\s overall health condition. The one of the most common health effects of whole body vibration is impact on musculoskeletal system. In many studies, indicated that whole-body vibration effect waist, back, shoulder and neck especially. There were varied studies that hormone levels were not changed as well there were varied studies that hormone levels were increased or decreased. There were varied studies about the digestive and circulatory system. In these studies, digestive system complaints, peptic ulcer, gastritis, varicose veins and hemorrhoids were determined frequently. For protection the health effect of vibration, Directives of the European Commission, Turkish Standards, Assessment and Management of Environmental Noise and Vibration Regulations were published. For the control of vibration are need technical and medical measures and education [TAF Prev Med Bull 2014; 13(2.000: 177-186

    Full Text Available In the recent years, there have been considerable discussion and concern about the possible hazards of RF/MW radiation. More recently, the growth and development in personal mobile communications have focused attention on the frequencies associated with this technology. A number of studies have examined the health effects of RF/MW electromagnetic fields (EMFs, originating from occupational exposure, hobbies, or residence near the radio or television transmitters. Particularly controversial are the biophysical mechanisms by which these RF fields may affect biological systems. General health effects reviews explore possible carcinogenic, reproductive and neurological effects. Health effects by exposure source have been observed in radar traffic devices, wireless communications with cellular phones, radio transmission, and magnetic resonance imaging (MRI. Several epidemiological surveys have suggested associations with non-specific complaints such as headache, tiredness, sleep disturbance, loss of memory, and dizziness. These findings, which echo reports of illness associated with other types of radiofrequency (RF radiation, relate not only to the use of mobile phones, but also to residence near the mobile phone base stations and other settings involving occupational exposure. The biological effects suggest that some precautions are necessary, and preventive approaches are highly recommended. Further researches are required to give more information about the effects of microwave radiation on our health, especially in occupational setting and professionally exposed workers.

    To investigate whether residents in the vicinity of the Sea Empress tanker spill suffered an increase in self reported physical and psychological symptoms, which might be attributable to exposure to crude oil. Retrospective cohort study; postal questionnaire including demographic details, a symptom checklist, beliefs about health effects of oil and the Hospital Anxiety and Depression and SF-36 mental health scales. Populations living in four coastal towns on the exposed south Pembrokeshire coast and two control towns on the unexposed north coast. 539 exposed and 550 unexposed people sampled at random from the family health services authority age-sex register who completed questionnaires. Adjusted odds ratios for self reported physical symptoms; scores on the Hospital Anxiety and Depression and SF-36 mental health scales, in 1089 people who responded out of a possible 1585 (69%). Living in areas exposed to the crude oil spillage was significantly associated with higher anxiety and depression scores, worse mental health; and self reported headache (odds ratio = 2.35, 95% CI 1.56, 3.55), sore eyes (odds ratio = 1.96, 95% CI 1.06, 3.62), and sore throat (odds ratio = 1.70, 95% CI 1.12, 2.60) after adjusting for age, sex, smoking status, anxiety, and the belief that oil had affected health. People living in exposed areas reported higher rates of physical and psychological symptoms than control areas. Symptoms significantly associated with exposure after adjustment for anxiety and health beliefs were those expected from the known toxicological effect of oil, suggesting a direct health effect on the exposed population.

    Household air pollution is a leading cause of disability-adjusted life years in Southeast Asia and the third leading cause of disability-adjusted life years globally. There are at least sixty sources of household air pollution, and these vary from country to country. Indoor tobacco smoking, construction material used in building houses, fuel used for cooking, heating and lighting, use of incense and various forms of mosquito repellents, use of pesticides and chemicals used for cleaning at home, and use of artificial fragrances are some of the various sources that contribute to household air pollution. Household air pollution affects all stages of life with multi-systemic health effects, and its effects are evident right from pre-conception to old age. In utero exposure to household air pollutants has been shown to have health effects which resonate over the entire lifetime. Exposures to indoor air pollutants in early childhood also tend to have repercussions throughout life. The respiratory system bears the maximum brunt, but effects on the cardiovascular system, endocrine system, and nervous system are largely underplayed. Household air pollutants have also been implicated in the development of various types of cancers. Identifying household air pollutants and their health implications helps us prepare for various health-related issues. However, the real challenge is adopting changes to reduce the health effects of household air pollution and designing innovative interventions to minimize the risk of further exposure. This review is an attempt to understand the various sources of household air pollution, the effects on health, and strategies to deal with this emergent risk factor of global mortality and morbidity.

    Community health worker (CHW) interventions improve health outcomes of patients from underserved communities, but health professionals' perceptions of their effectiveness may impede integration of CHWs into health care delivery systems. Whether health professionals' attitudes and skills, such as those related to cultural competence, influence perceptions of CHWs, is unknown. A questionnaire was administered to providers and clinical staff from 6 primary care practices in Maryland from April to December 2011. We quantified the associations of self-reported cultural competence and preparedness with attitudes toward the effectiveness of CHWs using logistic regression adjusting for respondent age, race, gender, provider/staff status, and years at the practice. We contacted 200 providers and staff, and 119 (60%) participated. Those reporting more cultural motivation had higher odds of perceiving CHWs as helpful for reducing health care disparities (odds ratio [OR] = 9.66, 95% confidence interval [CI] = 3.48-28.80). Those reporting more frequent culturally competent behaviors also had higher odds of believing CHWs would help reduce health disparities (OR = 3.58, 95% CI = 1.61-7.92). Attitudes toward power and assimilation were not associated with perceptions of CHWs. Cultural preparedness was associated with perceived utility of CHWs in reducing health care disparities (OR = 2.33, 95% CI = 1.21-4.51). Providers and staff with greater cultural competence and preparedness have more positive expectations of CHW interventions to reduce healthcare disparities. Cultural competency training may complement the use of CHWs and support their effective integration into primary care clinics that are seeking to reduce disparities. © The Author(s) 2014.

  11. A health hierarchy of effects model: a synthesis of advertising and health hierarchy conceptualizations.

    1991-01-01

    Work by both advertising and health researchers has independently yielded hierarchy of effects models which can be used to predict campaign success. Unfortunately, however, previous work has been criticized as "common sense" approaches which are more "assumed" than "proven." This analysis argues that much of the problem is due to the lack of precision often associated with over-simplified "uni-dimensional" models. Instead, this perspective synthesized a "two-dimensional" health hierarchy of effects model and outlines a pragmatic strategy for campaign measurement.

  12. Blood-borne biomarkers and bioindicators for linking exposure to health effects in environmental health science.

    Environmental health science aims to link environmental pollution sources to adverse health outcomes to develop effective exposure intervention strategies that reduce long-term disease risks. Over the past few decades, the public health community recognized that health risk is driven by interaction between the human genome and external environment. Now that the human genetic code has been sequenced, establishing this "G × E" (gene-environment) interaction requires a similar effort to decode the human exposome, which is the accumulation of an individual's environmental exposures and metabolic responses throughout the person's lifetime. The exposome is composed of endogenous and exogenous chemicals, many of which are measurable as biomarkers in blood, breath, and urine. Exposure to pollutants is assessed by analyzing biofluids for the pollutant itself or its metabolic products. New methods are being developed to use a subset of biomarkers, termed bioindicators, to demonstrate biological changes indicative of future adverse health effects. Typically, environmental biomarkers are assessed using noninvasive (excreted) media, such as breath and urine. Blood is often avoided for biomonitoring due to practical reasons such as medical personnel, infectious waste, or clinical setting, despite the fact that blood represents the central compartment that interacts with every living cell and is the most relevant biofluid for certain applications and analyses. The aims of this study were to (1) review the current use of blood samples in environmental health research, (2) briefly contrast blood with other biological media, and (3) propose additional applications for blood analysis in human exposure research.

  13. Building institutions for an effective health system: lessons from China's experience with rural health reform.

    Science.gov (United States)

    Bloom, Gerald

    2011-04-01

    This paper is concerned with the management of health system changes aimed at substantially increasing the access to safe and effective health services. It argues that an effective health sector relies on trust-based relationships between users, providers and funders of health services, and that one of the major challenges governments face is to construct institutional arrangements within which these relationships can be embedded. It presents the case of China, which is implementing an ambitious health reform, drawing on a series of visits to rural counties by the author over a 10-year period. It illustrates how the development of reform strategies has been a response both to the challenges arising from the transition to a market economy and the result of actions by different actors, which have led to the gradual creation of increasingly complex institutions. The overall direction of change has been strongly influenced by the efforts made by the political leadership to manage a transition to a modern economy which provides at least some basic benefits to all. The paper concludes that the key lessons for other countries from China's experience with health system reform are less about the detailed design of specific interventions than about its approach to the management of institution-building in a context of complexity and rapid change.

    Full Text Available The aim of this study was to determine the risky health behaviors and to raise the awareness of adolescents (attending high school education about prevention of risky behaviors and solutions by the effect of module-based training courses (about reproductive health and birth control, sexually transmitted infections, harmful habits, psychosocial behavior. Being planned as cross-sectional, this study was performed between September 2013-June 2014 in three states and a private high school in Zonguldak and conducted with a group of students aged between 14 and 19.926 students have participated before the training and 534 students have participated after training. It was seen that the mean scores of ‘The Adolescent Risk-Taking Questionnaire', ‘The Adolescent's Attitudes Towards Violence Scale' and ‘taking risk about social status', ‘traffic', ‘subtance use' subscales have decreased after the risk prevention trainings. The means scores of ‘Adolescent Coping with Problems Scale', ‘Nutrition Behaviour Scale' and ‘Nutrition Attitude Scale' have raised. Hence, the scores of domains reflecting adolescent health perception such as hygiene, sleep and exercise have raised while the scores of somatic symptoms domain, such as abdominal pain, headache, and fatigue have been failed. Consequently, it was determined that the training courses about risky health behaviours were effective in preventing risky health behaviors and creating positive health perceptions of adolescents.

    This paper adds to the literature on social capital and health by testing whether an exogenous shock in the health of a family member (a new baby) affects the family's investment in social capital. It also contributes to a small but growing literature on the effects of children's health on family resources and provides information about associations between health and social capital in a socioeconomically disadvantaged population. We use data from the Fragile Families and Child Wellbeing study, a longitudinal survey of about 5000 births to mostly unwed parents in 20 U.S. cities during the years 1998-2000. Both parents were interviewed at the time of the birth and then again one and three years later. The infants' medical records from the birth hospitalization were reviewed, and poor infant health was characterized to reflect serious and random health problems that were present at birth. Social interactions, reported at three years, include the parents' participation in church groups, service clubs, political organizations, community groups, and organizations working with children; regular religious attendance; and visiting relatives with the child. Education, employment, wages, and sociodemographic characteristics are included in the analyses. The results suggest that infant health shocks do not affect the parents' social interactions.

    Communication failures between physicians and nurses are one of the most common causes of adverse events for hospitalized patients, as well as a major root cause of all sentinel events. Communication technology (ie, the electronic medical record, computerized provider order entry, email, and pagers), which is a component of health information technology (HIT), may help reduce some communication failures but increase others because of an inadequate understanding of how communication technology is used. Increasing use of health information and communication technologies is likely to affect communication between nurses and physicians. The purpose of this study is to describe, in detail, how health information and communication technologies facilitate or hinder communication between nurses and physicians with the ultimate goal of identifying how we can optimize the use of these technologies to support effective communication. Effective communication is the process of developing shared understanding between communicators by establishing, testing, and maintaining relationships. Our theoretical model, based in communication and sociology theories, describes how health information and communication technologies affect communication through communication practices (ie, use of rich media; the location and availability of computers) and work relationships (ie, hierarchies and team stability). Therefore we seek to (1) identify the range of health information and communication technologies used in a national sample of medical-surgical acute care units, (2) describe communication practices and work relationships that may be influenced by health information and communication technologies in these same settings, and (3) explore how differences in health information and communication technologies, communication practices, and work relationships between physicians and nurses influence communication. This 4-year study uses a sequential mixed-methods design, beginning with a

    Full Text Available Alcoholism is a complex biopsychosocial disorder that requires a specialised and multidisciplinary approach focusing on both the patient and the family. Alcohol consumption is the most important addiction worldwide due to its prevalence and impact. Therefore, the main objective of a primary care physician should be to facilitate the referral of patients and their families to a structured treatment, support and guidance program during the whole detoxification process. In every health area in Cienfuegos, there are community mental health centers with a staff trained to deal with these disorders in addicts and their family. A literature review was conducted to establish the relationship between alcohol consumption and its harmful effects on health, family and society, using an approach based on Health Psychology.

    Evaluation of the effectiveness of a workplace health promotion program on employees' vitality, health, and work-related outcomes, and exploring the influence of organizational support and the supervisors' role on these outcomes. The 5-month intervention included activities at management, team, and individual level targeting self-management to perform healthy behaviors: a kick-off session, vitality training sessions, workshops, individual coaching, and intervision. Outcome measures were collected using questionnaires, health checks, and sickness absence data at baseline, after the intervention and at 10 months follow-up. For analysis linear and generalized mixed models were used. Vitality, work performance, sickness absence, and self-management significantly improved. Good organizational support and involved supervisors were significantly associated with lower sickness absence. Including all organizational levels and focusing on increasing self-management provided promising results for improving vitality, health, and work-related outcomes.

  1. The effects of poverty on children's development and oral health.

    da Fonseca, Marcio A

    2012-01-01

    According to the US Census Bureau, the poverty rate for children under 18 years of age increased to 22% in 2010. Poverty leads to adverse health outcomes in children and adolescents such as harmful effects on learning, psychosocial development, physical health, productivity and family life. Because the citizens and residents of a country are its most valuable assets, it is unwise to allow housing instability, food insecurity and hunger to continue to exist at its current levels. Reducing poverty is likely to prevent illnesses, decrease hospitalizations, and lead to lower health care costs. There is also a need for intervention strategies to ensure equitable access to healthy foods across the world. Children who are food insecure are more likely to be in poor health and to have poor nutritional outcomes. Poverty may lead to poor dental health due to malnutrition or incorrect diet and it may also have an effect on the child's behavior in the dental office. An understanding of poverty will lessen the anger, frustration and prejudice that pediatric dentists may feel when working with low-income families. This manuscript presents a concise overview of the effects of poverty in children's lives.

    Minority communities often bear the burden of "hosting" pollution sources. This report assesses whether there are any health effects from living near such pollution sources and whether health effects of pollution vary by sex, ethnicity, or income. The air pollution emissions from Hartford area, point sources are modeled and exposures are estimated for the residents who participated in a geographically-based health survey. The pollution intensities and other individual and neighborhood characteristics are used to predict an individual's reported respiratory problems. The results indicate that respiratory problems are correlated significantly with pollution levels, especially sulfur dioxide from the local trash-to-energy incinerator-the fifth largest one in the U.S. The effects of a given pollution level tend to be more serious for specific subgroups based upon sex, ethnicity, poverty, and age. Even when controlling for other factors, air pollution levels are significantly correlated with health problems, especially for Hispanics. This air pollution may contribute to health disparities. © 2015 National Medical Association. Published by Elsevier Inc. All rights reserved.

    2007-01-01

    The purpose of this paper is to evaluate the views of stove users in Ulaanbaatar, Mongolia on how stoves affect their health. In this paper focus groups were conducted with improved stove users; traditional stove users; and a mix of traditional and improved stove users. Individual interviews were also held with various types of stove users. A translator moderated all discussions with a questioning route. All discussions were fully transcribed and translated. The transcripts were analysed by identifying common themes in responses to form an emerging theory. The findings in the paper are that all stove users recognised respiratory symptoms caused by stove smoke and other health effects such as warmth, dirt and workload, which they perceived to be important. Stove users had a lack of knowledge about the diseases caused by the smoke. Public health was a key driver for the improved stove project, yet has been neglected in improved stove marketing. The study used in this paper was limited by the language barrier. Some of the meanings of participants' responses may have been lost in translation. This paper has highlighted the importance of the health effects of stove smoke to stove users. Uptake of the improved stoves has been low. Public health should be included in marketing strategies for improved stoves to increase their uptake. The paper shows that acute respiratory infections are a major cause of mortality world-wide. Indoor air pollution from burning biomass fuels in household stoves causes a significant proportion of respiratory infections. No qualitative research has been published exploring stove users' views on the health effects of stoves. This paper provides an insight into stove users' perceptions for those interested in people-centred approaches to tackling international health issues.

  4. Does income inequality have lasting effects on health and trust?

    Rözer, Jesper Jelle; Volker, Beate

    2016-01-01

    According to the income inequality hypothesis, income inequality is associated with poorer health. One important proposed mechanism for this effect is reduced trust. In this study, we argue that income inequality during a person's formative years (i.e., around age 16) may have lasting consequences for trust and health. Multilevel analyses of data from the combined World Values Survey and European Values Study that were collected between 1981 and 2014 support our prediction and show that income inequality is associated with ill health in young adults, in part because it reduces their social trust. The negative consequences of income inequality remain stable for a substantial period of life but eventually fade away and have no effect after age 36. Copyright © 2015 Elsevier Ltd.

    Many international organizations have developed health risk models. Especially, as radiation-induced cancer is an important part among health effects, development has been focused on cancer risk model. This paper reviewed the cancer risk models of international agencies; United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), National Academy of Sciences (NAS) and International Commission on Radiological Protection (ICRP). Moreover, as pre-research for improving the health risk model in Korea, this paper analyzed the three methodologies and specific details in modeling. International agencies have developed radiation-induced cancer risk model reflecting the recent A-bomb survivor LSS data. This paper reviewed the recent cancer risk model of UNSCEAR, NAS and ICRP. All three models were based on ERR and EAR model in the form of a multiplication of dose-response model and modification function. Lifetime risk was calculated as a function of exposure age and gender.

Positive and negative changes were recorded over time, and then, the study data were analyzed using Chi-square (bonferroni adjustment, McNemar, Kruskal-Wallis  and Paired t-Test. Results: The study results revealed no significant differences between the  halitosis group and the traditional group, though both had a significant difference with the control group. Positive changes in halitosis group especially within girls were held to be more durable compared to the other groups. Conclusion: Oral health training accompanging training of oral malodor, tooth decay and periodontal disease seems to be more effective on health promotion of senior high school students in Yazd. Furthermore, oral malodor training produces more durable effects. As a result, this training style is recommended in regard with eductional programs of schools.

    The herbicide glyphosate, N-(phosphonomethyl) glycine, has been used extensively in the past 40years, under the assumption that side effects were minimal. However, in recent years, concerns have increased worldwide about the potential wide ranging direct and indirect health effects of the large scale use of glyphosate. In 2015, the World Health Organization reclassified glyphosate as probably carcinogenic to humans. A detailed overview is given of the scientific literature on the movement and residues of glyphosate and its breakdown product aminomethyl phosphonic acid (AMPA) in soil and water, their toxicity to macro- and microorganisms, their effects on microbial compositions and potential indirect effects on plant, animal and human health. Although the acute toxic effects of glyphosate and AMPA on mammals are low, there are animal data raising the possibility of health effects associated with chronic, ultra-low doses related to accumulation of these compounds in the environment. Intensive glyphosate use has led to the selection of glyphosate-resistant weeds and microorganisms. Shifts in microbial compositions due to selective pressure by glyphosate may have contributed to the proliferation of plant and animal pathogens. Research on a link between glyphosate and antibiotic resistance is still scarce but we hypothesize that the selection pressure for glyphosate-resistance in bacteria could lead to shifts in microbiome composition and increases in antibiotic resistance to clinically important antimicrobial agents. We recommend interdisciplinary research on the associations between low level chronic glyphosate exposure, distortions in microbial communities, expansion of antibiotic resistance and the emergence of animal, human and plant diseases. Independent research is needed to revisit the tolerance thresholds for glyphosate residues in water, food and animal feed taking all possible health risks into account. Copyright © 2017 Elsevier B.V.

    In this Paper two elements of a multiphase analysis of radiation exposures in the living environment - the human health effects of ionizing radiation and the implications for radiation safety policy and practices - are presented. Part 1 draws together the current state of scientific knowledge and insight about the human health effects of radiation, describing these in terms of known cause-related deterministic effects and of the estimated incidence of stochastic effects as defined by biostatistics and biological models. The 1988 UNSCEAR report provides an authoritative basis for such an examination. Part 2 explores some of the major implications that the state-of-the-art of radiation biology has - or should have - for radiation safety policy and practices. (author)

  10. [New welding processes and health effects of welding].

    2011-01-01

    This paper describes some of the recent developments in the control technology to enhance capability of Pulse Gas Metal Arc Welding. Friction Stir Welding (FSW) processing has been also considered. FSW is a new solid-state joining technique. Heat generated by friction at the rotating tool softens the material being welded. FSW can be considered a green and energy-efficient technique without deleterious fumes, gas, radiation, and noise. Application of new welding processes is limited and studies on health effects in exposed workers are lacking. Acute and chronic health effects of conventional welding have been described. Metal fume fever and cross-shift decline of lung function are the main acute respiratory effects. Skin and eyes may be affected by heat, electricity and UV radiations. Chronic effects on respiratory system include chronic bronchitis, a benign pneumoconiosis (siderosis), asthma, and a possible increase in the incidence of lung cancer. Pulmonary infections are increased in terms of severity, duration, and frequency among welders.

  11. Problems in evaluating health effects of occupational and environmental exposures

    1981-01-01

    The assessment of health effects from low-level exposure to radiation is a matter of considerable controversy. Existing standards for exposure are based primarily on estimates of health effects obtained by extrapolation from effects of high-level exposures such as those experienced at Hiroshima and Nagasaki. Occupational and environmental exposures provide one source of data for this task. A number of studies of populations exposed in this manner have attracted recent attention. Because of the size of most of the groups and the magnitude of the exposures received, the amount that can be learned from such populations is severely limited. A number of the problems involved in analyzing and interpreting such data are addressed. Many of these problems are illustrated by a current study of the effects on mortality of occupational exposure to radiation at the Hanford plant

    Effecsts of UV radiation on human health are discussed. UV radiation is taken up through the skin and eyes. In the case of the eyes, the only known effects are damaging ones (e.g. cataracts). Irradiation of the skin, on the other hand, may either have a prophylactic and therapeutic effect or cause health problems if the exposure is too frequent and/or the dose too high. Positive effects are: Stimulation of the vitamin-D-3 synthesis and the autoimmune system, economisation of blood circulation, higher fitness, and the development of a UV protection system in the skin. Negative effects are: UV erythema, disturbances of the unspecific resistance and the immune system, and photocarcinogenesis. (orig.) [de

  13. Radiation and health effects. A report on the TMI-2 accident and related health studies

    International Nuclear Information System (INIS)

    1986-08-01

    On March 28, 1979, the Unit 2 reactor at the Three Mile Island (TMI) Nuclear Station was severely damaged by an accident. Radioactivity was discharged to the environment resulting in a small amount of radiation exposure to the public. Continuing concerns by some members of the communities around TMI about the potential radiation-induced health effects prompted GPU Nuclear Corporation to examine the information gathered from the accident investigation in the context of our current knowledge of radiation and its effects on human health. Although this report deals with technical matters, the information is presented in a manner that can be understood by those who do not have scientific backgrounds. This report is divided into three major sections. The first section provides an overview of the past 80 years of relevant research on the subject of radiation and its effects on human health. During that time, scientists and physicians throughout the world have studied hundreds of thousands of individuals exposed to radiation from medical and occupational sources and from nuclear weapons explosions. Epidemiologic studies of humans, such as the Japanese survivors of the atomic bomb, have established that following exposure to large doses of radiation, certain health effects, including cancer, can be observed. Radiation-induced health effects from low doses of radiation, such as those associated with the TMI-2 accident, appear infrequently, if at all, and are identical and, therefore, indistinguishable from similar health effects which occur normally. For example, cancers induced by radiation are indistinguishable from those occurring spontaneously or normally. It is not possible, therefore, for scientists to determine directly whether radiation-induced health effects at low doses occur at all; such observations can only be inferred by statistical methods. The second section of this report provides a brief description of the TMI-2 accident. Most of the radioactivity from the

    Air freshener could be one of the multiple sources that release volatile organic compounds (VOCs) into the indoor environment. The use of these products may be associated with an increase in the measured level of terpene, such as xylene and other volatile air freshener components, including aldehydes, and esters. Air freshener is usually used indoors, and thus some compounds emitted from air freshener may have potentially harmful health impacts, including sensory irritation, respiratory symptoms, and dysfunction of the lungs. The constituents of air fresheners can react with ozone to produce secondary pollutants such as formaldehyde, secondary organic aerosol (SOA), oxidative product, and ultrafine particles. These pollutants then adversely affect human health, in many ways such as damage to the central nervous system, alteration of hormone levels, etc. In particular, the ultrafine particles may induce severe adverse effects on diverse organs, including the pulmonary and cardiovascular systems. Although the indoor use of air freshener is increasing, deleterious effects do not manifest for many years, making it difficult to identify air freshener-associated symptoms. In addition, risk assessment recognizes the association between air fresheners and adverse health effects, but the distinct causal relationship remains unclear. In this review, the emitted components of air freshener, including benzene, phthalate, and limonene, were described. Moreover, we focused on the health effects of these chemicals and secondary pollutants formed by the reaction with ozone. In conclusion, scientific guidelines on emission and exposure as well as risk characterization of air freshener need to be established.

  18. Health effects of air quality regulations in Delhi, India

    2011-03-01

    This, the first systematic study, quantifies the health effects of air quality regulations in Delhi, which adopted radical measures to improve air quality, including, for example, the conversion of all commercial vehicles to compressed natural gas (CNG), and the closure of polluting industries in residential areas from 2000 to 2002. Air pollution data, collected at 113 sites (spread across Delhi and its neighboring areas) from July-December 2003, were used to compute exposure at the place of residence of 3989 subjects. A socio-economic and respiratory health survey was administered in 1576 households. This survey collected time-use, residence histories, demographic information, and direct measurements of lung function with subjects. The optimal interpolation methods were used to link air pollution and respiratory health data at the place of their residence. Resident histories, in combination with secondary data, were used to impute cumulative exposure prior to the air-quality interventions, and the effects of recent air quality measures on lung function were then evaluated. Three important findings emerge from the analysis. First, the interventions were associated with a significant improvement in respiratory health. Second, the effect of these interventions varied significantly by gender and income. Third, consistent with a causal interpretation of these results, effects were the strongest among those individuals who spend a disproportionate share of their time out-of-doors.

  4. Health and psychosocial effects of flexible working hours.

    2004-12-01

    To examine whether any impairments in health and social lives can be found under different kinds of flexible working hours, and whether such effects are related to specific characteristics of these working hours. Two studies -- a company based survey (N=660) and an internet survey (N=528) -- have been conducted. The first one was a questionnaire study (paper and pencil) on employees working under some 'typical' kinds of different flexible working time arrangements in different companies and different occupational fields (health care, manufacturing, retail, administration, call centres). The second study was an internet-based survey, using an adaptation of the questionnaire from the first study. The results of both studies consistently show that high variability of working hours is associated with increased impairments in health and well-being and this is especially true if this variability is company controlled. These effects are less pronounced if variability is self-controlled; however, autonomy does not compensate the effects of variability. Recommendations for an appropriate design of flexible working hours should be developed in order to minimize any impairing effects on health and psychosocial well-being; these recommendations should include -- besides allowing for discretion in controlling one's (flexible) working hours -- that variability in flexible working hours should be kept low (or at least moderate), even if this variability is self-controlled.

    The aim of this project was to identify effective recruitment and retention strategies used by health-promotion organisations that focus on increasing physical activity and improving nutrition within the local community. Semistructured telephone or face-to-face interviews with 25 key informants from stakeholder organisations were conducted. Key informants discussed strategies used by their organisation to effectively recruit and retain participants into community-based healthy eating and/or physical activity programs. Transcribed data were analysed with NVivo software. Effective recruitment strategies included word of mouth, links with organisations, dissemination of printed materials, media, referrals, cross-promotion of programs and face-to-face methods. Effective retention strategies included encouraging a sense of community ownership, social opportunities, recruiting a suitable leader and offering flexibility and support. Fees and support for recruiting and retaining participants was also identified. This study provides novel insights to a greatly under researched topic in the field of health promotion. There are two key take-home messages from the present study that are applicable to health practitioners as well as developers and deliverers of community health-promotion programs: (1) it is imperative that all community health organisations report on the effectiveness of their recruitment and retention, both successes and failures; and (2) there is a clear need to tailor the recruitment and retention approach to the target population and the setting the program is occurring in. SO WHAT? These findings provide important insights for the development of future community-based healthy eating and physical activity programs.

    2018-02-01

    A strategy of customisation, and its subsequent practical implementation as part of personalised treatment pathways, is an appropriate approach to increase benefits for patients and to strengthen the competitive position of the provider of health services. This requires restructuring and/or reorganising measures to enable variants within the treatment pathway as a value creation process to be adapted to each individual patient and his illness, living conditions and preferences. This 'mass customisation' approach allows us to achieve the objective of a constructive interconnection of customisation and standardisation of health services. Major, rapid progress in information and communication technology plays a key part in this process. Focused design tools for mass customisation are the integration of patients into the service delivery process and the modularisation of processes and organisation. By taking into account the specificities of health services as a confidence good these design tools are featured and supported by operational and organisational tools in order to develop variants. This approach allows for high-quality health services that are perfectly tailored to individual patients' needs and, at the same time, delivered in an economic way. On this basis, customised approaches for personalised health diagnosis and therapy provide patient-focused health services that manage to apply the concept of value-based healthcare in a sophisticated and effective form.

    This study was to evaluate the effect of additional brief counseling by a primary care physician on lifestyle modification of examinees after a periodic health examination. 1,000 participants of the 2007 Korean national health screening program were asked to note any variation in their health behavior after participating in the screening program. The degree of comprehensive motivation for lifestyle modification was assessed in terms of stages of health behavior change. We calculated odds ratio of positive change (enhanced stage of change) with multiple logistic regression analysis and age-adjusted proportion of positive changers. Of 989 respondents, 486 and 503 received the basic and additional programs, respectively. Additional group were more likely to be positive changer than basic group (adjusted OR 1.78; 95% CI 1.19-2.65), and this was more prominent in older age group (adjusted OR 2.38, 95% CI 1.23-4.58). The age-adjusted proportions of positive changers were 22.7% (95% CI, 17.9-28.3) and 36.2% (95% CI, 30.4-42.4) in the basic and additional groups, respectively (P behavior change after the health examination. Thus, such a consultation should be considered when designing a health-screening program.

    Wind power has been harnessed as a source of power around the world. Debate is ongoing with respect to the relationship between reported health effects and wind turbines, specifically in terms of audible and inaudible noise. As a result, minimum setback distances have been established world-wide to reduce or avoid potential complaints from, or potential effects to, people living in proximity to wind turbines. People interested in this debate turn to two sources of information to make informed decisions: scientific peer-reviewed studies published in scientific journals and the popular literature and internet. The purpose of this paper is to review the peer-reviewed scientific literature, government agency reports, and the most prominent information found in the popular literature. Combinations of key words were entered into the Thomson Reuters Web of KnowledgeSM and the internet search engine Google. The review was conducted in the spirit of the evaluation process outlined in the Cochrane Handbook for Systematic Reviews of Interventions. Conclusions of the peer reviewed literature differ in some ways from those in the popular literature. In peer reviewed studies, wind turbine annoyance has been statistically associated with wind turbine noise, but found to be more strongly related to visual impact, attitude to wind turbines and sensitivity to noise. To date, no peer reviewed articles demonstrate a direct causal link between people living in proximity to modern wind turbines, the noise they emit and resulting physiological health effects. If anything, reported health effects are likely attributed to a number of environmental stressors that result in an annoyed/stressed state in a segment of the population. In the popular literature, self-reported health outcomes are related to distance from turbines and the claim is made that infrasound is the causative factor for the reported effects, even though sound pressure levels are not measured.

    There is little evidence about the effects of environmental interventions on population levels of physical activity. Major transport projects may promote or discourage physical activity in the form of walking and cycling, but researching the health effects of such "natural experiments" in transport policy or infrastructure is challenging. Case study of attempts in 2004-2005 to evaluate the effects of two major transport projects in Scotland: an urban congestion charging scheme in Edinburgh, and a new urban motorway (freeway) in Glasgow. These interventions are typical of many major transport projects. They are unique to their context. They cannot easily be separated from the other components of the wider policies within which they occur. When, where, and how they are implemented are political decisions over which researchers have no control. Baseline data collection required for longitudinal studies may need to be planned before the intervention is certain to take place. There is no simple way of defining a population or area exposed to the intervention or of defining control groups. Changes in quantitative measures of health-related behavior may be difficult to detect. Major transport projects have clear potential to influence population health, but it is difficult to define the interventions, categorize exposure, or measure outcomes in ways that are likely to be seen as credible in the field of public health intervention research. A final study design is proposed in which multiple methods and spatial levels of analysis are combined in a longitudinal quasi-experimental study.

  17. Health effects of low frequency electric and magnetic fields

    1992-06-01

    The US Department of Labor and the President's Office of Science and Technology Policy (STP) requested that the Committee on interagency Radiation Research and Policy Coordination (CIRRPC) conduct an independent evaluation of the reported health effects from exposure to low-frequency electric and magnetic fields (ELF-EMF), especially reports of carcinogenesis and reproductive and neurophysiological effects focusing on frequencies which appeared to be of greatest public concern. Oak Ridge Associated Universities (ORAU) was tasked by the CIRRPC to oversee the review by a panel of independent, non-Federal, scientists. Following their review of over 1000 journal articles, the ORAU Panel concluded ''... that there is no convincing evidence ... to support the contention that exposure to ELF-EMF generated by sources such as household appliances, video display terminals (10 to 30 KHz), and local power lines (15 to 180 Hz) are demonstrable health hazards.'' Although the Panel noted that some biological effects produced by these fields may be of scientific interest and warrant consideration for future research, it concluded that ''... in the broad scope of research needs in basic science and health research, any health concerns over exposures to these fields should not receive a high priority.'' This executive summary outlines the panel's investigation

    Gill, Harsharn S.; Grover, Sunita; Batish, Virender K.; Gill, Preet

    Probiotics are defined as live microorganisms which when administered in adequate amounts confer a health benefit upon the host (FAO/WHO, 2001). Lactic acid bacteria, particularly Lactobacillus and Bifidobacterium species are commonly used as probiotics. Other less commonly used probiotics include the yeast Sacchromyces cerevisiae and some non-pathogenic Escherichia coli and Bacillus species. Studies over the past 20 years have demonstrated that probiotic intake is able to confer a range of health benefits including modulation of the immune system, protection against gastrointestinal and respiratory tract infections, lowering of blood cholesterol levels, attenuation of overt immuno-inflammatory disorders (such as inflammatory bowel disease, allergies) and anti-cancer effects. However, the strongest clinical evidence for probiotics relates to their effectiveness in improving gut health and modulating (via stimulation or regulation) the host immune system. This chapter provides an overview of the current status of our knowledge regarding the immunostimulatory and immunoregulatory effects of probiotics on the immune system and their significance to human health.

    A main source of outdoor air pollution is road traffic, which produces a complex mixture of nitrogen oxides, carbon monoxide, volatile hydrocarbons, airborne particles and some other compounds. Traffic exhaust affects also the concentrations of ozone and other photo chemical oxidants. In earlier studies those components have had remarkable health effects. Several studies on occupational exposure to automobile exhaust have been published and several studies have been observed an association between both outdoor and indoor pollutant levels and health outcomes. However, there are only a few epidemiological studies in which traffic exhaust, a complex mixture, has been studied in its entirety. During recent years, interesting epidemiological studies of the health effects of this complex mixture have been published. Human exposure assessment for traffic exhaust can be categorized according to the environment of exposure (indoors, outdoors, in-traffic) or to the method of exposure assessment (direct or indirect methods). In this presentation the methods are further categorized into (1) traffic activity, (2) air concentration measurements, and (3) dispersion models, in order to better understand the advantages and disadvantages of different approaches. The objective of this presentation is to make a critical review of exposure assessments in the epidemiological studies on health effects of traffic exhaust. (author)

    The short- and medium-term effects of conflict on population health are reasonably well documented. Less considered are its consequences across generations and potential harms to the health of children yet to be born. Looking first at the nature and effects of exposures during conflict, and then at the potential routes through which harm may propagate within families, we consider the intergenerational effects of four features of conflict: violence, challenges to mental health, infection and malnutrition. Conflict-driven harms are transmitted through a complex permissive environment that includes biological, cultural and economic factors, and feedback loops between sources of harm and weaknesses in individual and societal resilience to them. We discuss the multiplicative effects of ongoing conflict when hostilities are prolonged. We summarize many instances in which the effects of war can propagate across generations. We hope that the evidence laid out in the article will stimulate research and--more importantly--contribute to the discussion of the costs of war; particularly in the longer-term in post-conflict situations in which interventions need to be sustained and adapted over many years.

    Full Text Available Heavy metals form a versatile group of high density elements that vary considerably in their biological roles and chemical properties. Although many heavy metals are essential trace elements yet they have long been recognized as environmental pollutants due their toxic effects. Increased industrialization, urbanization anthropogenic activities like mining, smelting and other agricultural activities have resulted in accumulation of heavy metals in the environment. Heavy metals such as nickel, cadmium, zinc, copper, mercury, arsenic and chromium are not easily degradable and tend to build up in soil. These heavy metals through various routes such as fish and plants make their way into the human body and are known to have serious detrimental effects on human health at elevated levels. The harmful effects of some important heavy metals on human health have been discussed.

    Full Text Available Electronic Health Record EHR systems enhance efficiency and effectiveness in handling patients information in healthcare. This study focused on the EHR security by initially establishing the nature of threats affecting the system and reviewing the implemented security safeguards. The study was done at a referral hospital level 6 government facility in Kenya. Purposive sampling was used to select a sample of 196 out of 385 staff and a questionnaire designed for qualitative data collection. Data was analyzed using SPSS software. Correlations and binary logistic regression were obtained. Binary Logistic Regression BLR was used to establish the effect of the safeguards predictors on EHR security. It was established that physical security contributes more to the security of an information system than administrative controls and technical controls in that order. BLR helped in predicting effective safeguards to control EHR security threats in limited resourced public health facilities.

    The author wanted to test the effects of preventive mental health programmes in schools and established a longitudinal study with a test group and a control group, using Solomon's method. Data was collected through questionnaires prior to intervention and at 1, 6, 12, and 24 months after the intervention. The size of the effect on the various indices were estimated in terms of (a) differences in improvement of total percentage scores and (b) Cohen's d. From to to t1, t2 and t3 the intervention group showed significantly greater progress in six out of seven knowledge indexes, and 12 months later we found significant effects on the level of mental health problems.

    This article contains a summary discussion of human health effects linked to indoor air pollution (UP) in homes and other non-industrial environments. Rather than discussing the health effects of the many different pollutants which can be found in indoor air, the approach has been to group broad...... these are respiratory disease (particularly among children), allergy (particularly to house dust mites) and mucous membrane irritation (particularly due to formaldehyde). Large numbers of people have been, and are still being affected. Many chemicals encountered in indoor air are known or suspected to cause sensory...... irritation or stimulation. These, in turn, may give rise to a sense of discomfort and other symptums cummonly reported in so-called “sick” buildings. Camplex mixtures of organic chemicals in indoor air also have the potential to invoke subtle effects on the central and peripheral nervous system, leading...

    2018-01-01

    There is a substantial proportion of the population using fixed metallic oral appliances, such as crowns and bridges, which are composed of various dental alloys. These restorations may be associated with a number of effects on oral health with variable degrees of severity, to review potential effects of using fixed metallic oral appliances, fabricated from various alloys. The MEDLINE/PubMed database was searched using certain combinations of keywords related to the topic. The search revealed that burning mouth syndrome, oral pigmentation, hypersensitivity and lichenoid reactions, and genotoxic and cytotoxic effects are the major potential oral health changes associated with fixed prosthodontic appliances. Certain oral disorders are associated with the use of fixed metallic oral appliances. Patch test is the most reliable method that can be applied for identifying metal allergy, and the simultaneous use of different alloys in the mouth is discouraged.

    Testicular cancer is diagnosed at a young age and survival rates are high; thus, the long-term effects of cancer treatment need to be assessed. Our objectives are to estimate the incidence rates and determinants of late effects in testicular cancer survivors. We conducted a population-based cohort study of testicular cancer survivors, diagnosed 1991-2007, followed up for a median of 10 years. We identified 785 testicular cancer patients who survived ≥5 years and 3323 men free of cancer for the comparison group. Multivariate Cox regression analysis was used to compare the hazard ratio between the cases and the comparison group and for internal analysis among case patients. Testicular cancer survivors experienced a 24 % increase in risk of long-term health effects >5 years after diagnosis. The overall incidence rate of late effects among testicular cancer survivors was 66.3 per 1000 person years. Higher risks were observed among testicular cancer survivors for hypercholesterolemia, infertility, and orchitis. Chemotherapy and retroperitoneal lymph node dissection appeared to increase the risk of late effects. Being obese prior to cancer diagnosis appeared to be the strongest factor associated with late effects. Testicular cancer survivors were more likely to develop chronic health conditions when compared to cancer-free men. While the late effects risk was increased among testicular cancer survivors, the incidence rates of late effects after cancer diagnosis was fairly low.

    Fragranced consumer products-such as air fresheners, cleaning supplies, and personal care products- pervade society. This study investigated the occurrence and types of adverse effects associated with exposure to fragranced products in Australia, and opportunities for prevention. Data were collected in June 2016 using an on-line survey with a representative national sample ( n  = 1098). Overall, 33% of Australians report health problems, such as migraine headaches and asthma attacks, when exposed to fragranced products. Of these health effects, more than half (17.1%) could be considered disabling under the Australian Disability Discrimination Act. Additionally, 7.7% of Australians have lost workdays or a job due to illness from fragranced product exposure in the workplace, 16.4% reported health problems when exposed to air fresheners or deodorizers, 15.3% from being in a room after it was cleaned with scented products, and 16.7% would enter but then leave a business as quickly as possible due to fragranced products. About twice as many respondents would prefer that workplaces, health care facilities and professionals, hotels, and airplanes were fragrance-free rather than fragranced. While 73.7% were not aware that fragranced products, even ones called green and organic, emitted hazardous air pollutants, 56.3% would not continue to use a product if they knew it did. This is the first study in Australia to assess the extent of adverse effects associated with exposure to common fragranced products. It provides compelling evidence for the importance and value of reducing fragranced product exposure in order to reduce and prevent adverse health effects and costs.

    Approximately one fifth of workers are engaged in some kind of shift work. The harmful effects of shift work on the health and work-life balance of employees are well known. A range of organizational interventions has been suggested to address these negative effects. This study undertook the systematic review (following Quality Of Reporting Of Meta [QUORUM] analyses guidelines) of experimental and quasi-experimental studies, from any country (in any language) that evaluated the effects on health and work-life balance of organizational-level interventions that redesign shift work schedules. Twenty-seven electronic databases (medical, social science, economic) were searched. Data extraction and quality appraisal were carried out by two independent reviewers. Narrative synthesis was performed. The review was conducted between October 2005 and November 2006. Twenty-six studies were found relating to a variety of organizational interventions. No one type of intervention was found to be consistently harmful to workers. However, three types were found to have beneficial effects on health and work-life balance: (1) switching from slow to fast rotation, (2) changing from backward to forward rotation, and (3) self-scheduling of shifts. Improvements were usually at little or no direct organizational cost. However, there were concerns about the generalizability of the evidence, and no studies reported on impacts on health inequalities. This review reinforces the findings of epidemiologic and laboratory-based research by suggesting that certain organizational-level interventions can improve the health of shift workers, their work-life balance, or both. This evidence could be useful when designing interventions to improve the experience of shift work.

    To assess the economic effect of the school-based obesity prevention program Planet Health on preventing disordered weight control behaviors and to determine the cost-effectiveness of the intervention in terms of its combined effect on prevention of obesity and disordered weight control behaviors. On the basis of the intervention's short-term effect on disordered weight control behaviors prevention, we projected the number of girls who were prevented from developing bulimia nervosa by age 17 years. We further estimated medical costs saved and quality-adjusted life years gained by the intervention over 10 years. As a final step, we compared the intervention costs with the combined intervention benefits from both obesity prevention (reported previously) and prevention of disordered weight control behaviors to determine the overall cost-effectiveness of the intervention. Middle schools. A sample of 254 intervention girls aged 10 to 14 years. The Planet Health program was implemented during the school years from 1995 to 1997 and was designed to promote healthful nutrition and physical activity among youth. Intervention costs, medical costs saved, quality-adjusted life years gained, and cost-effectiveness ratio. An estimated 1 case of bulimia nervosa would have been prevented. As a result, an estimated $33 999 in medical costs and 0.7 quality-adjusted life years would be saved. At an intervention cost of $46 803, the combined prevention of obesity and disordered weight control behaviors would yield a net savings of $14 238 and a gain of 4.8 quality-adjusted life years. Primary prevention programs, such as Planet Health, warrant careful consideration by policy makers and program planners. The findings of this study provide additional argument for integrated prevention of obesity and eating disorders.

    The extensive flooding in the aftermath of Hurricanes Katrina and Rita created conditions ideal for indoor mold growth, raising concerns about the possible adverse health effects associated with indoor mold exposure. Studies evaluating the levels of indoor and outdoor molds in the months following the hurricanes found high levels of mold growth. Homes with greater flood damage, especially those with >3 feet of indoor flooding, demonstrated higher levels of mold growth compared with homes with little or no flooding. Water intrusion due to roof damage was also associated with mold growth. However, no increase in the occurrence of adverse health outcomes has been observed in published reports to date. This article considers reasons why studies of mold exposure after the hurricane do not show a greater health impact.

  14. Methanol as an alternative fuel: Economic and health effects

    1991-01-01

    Switching from gasoline to methanol fuels has important economic and health effects. Replacing gasoline with methanol will affect oil markets by lowering the demand for oil and thus lowering oil prices. Increased demand for the natural gas feedstock will increase natural gas prices. Because methanol is more costly than gasoline, fuel prices will also increase. On the other hand, methanol use will reduce ozone pollution and some of the health risks associated with gasoline. Considering all three markets affected by the phasing-out of gasoline, the switch to methanol results in net gains. The health benefits from lower pollution and the lives saved from the switch from gasoline to methanol are in addition to these gains. Overall, the benefits of the policy far outweigh the costs. However, the gains in the oil market, arising from the US monopsony power in the world oil market, can be captured by other, more efficient policies. 21 refs., 2 figs., 3 tabs

    In this study, a health recreation program was implemented with elderly patients (60 years of age or older) who were receiving ubiquitous healthcare (u-healthcare) services. Furthermore, we examined the effects of health recreation on perceived stress, anxiety, and depression, by comparing survey results before and after the recreation program was conducted. Thus, the aim of this study was to develop an offline service with the ability to promote the impact of the u-healthcare service on mental healthcare. A health recreation program, consisting of a variety of weekly games, songs, and minilectures about mental health over a 10-week period, was offered at a senior citizens center in K-Gu, Seoul, Korea. This program targeted 18 elderly people currently receiving u-healthcare services. Data on the impact of the program on the mental health of the elderly were collected through surveys administered before and after the recreation program, and the results were compared with those of a control group. The control group consisted of 18 elderly people who were receiving u-healthcare services from the same district. The perceived stress and anxiety of the experimental group decreased significantly compared with those of the control group. However, the program did not result in a significant reduction in depression. This offline health recreation program offered to elderly u-healthcare service clients contributed to the promotion of their mental health. Further studies will be required to better incorporate the offline mental healthcare program into their daily lives within the u-healthcare service.

    2018-04-23

    It has not yet been possible to quantify dose-related health risks attributable to indoor dampness or mold (D/M), to support the setting of health-related limits for D/M. An overlooked target for assessing D/M is moisture in building materials, the critical factor allowing microbial growth. A search for studies of quantified building moisture and occupant health effects identified three eligible studies. Two studies assessed associations between measured wall moisture content and respiratory health in the UK. Both reported dose-related increases in asthma exacerbation with higher measured moisture, with one study reporting an adjusted odds ratio (OR) of 7.0 for night-time asthma symptoms with higher bedroom moisture. The third study assessed relationships between infrared camera-determined wall moisture and atopic dermatitis in South Korea, reporting an adjusted OR of 14.5 for water-damaged homes and moderate or severe atopic dermatitis. Measuring building moisture has, despite extremely limited available findings, potential promise for detecting unhealthy D/M in homes and merits more research attention. Further research to validate these findings should include measured "water activity," which directly assesses moisture availability for microbial growth. Ultimately, evidence-based, health-related thresholds for building moisture, across specific materials and measurement devices, could better guide assessment and remediation of D/M in buildings.

    Full Text Available This study investigated the effects of ethnicity and gender on the health of young people (14–25 years old living in Mauritius. Combinations of female and male by four ethnic groups—“Creole”, “Hindu”, “Muslim” and “Mixed”—were used for multivariate analysis of variances. “Mixed” ethnic group consumed most tobacco, alcohol and drugs compared to other ethnic groups. They were also the ones that mostly skipped breakfast and lunch and were found to eat most fast food. Moreover, “Mixed” ethnic group had heard most about HIV/AIDS programmes, but were least satisfied with such programmes and with public hospitals and health services. Females were shown to perceive more physical and mental health issues than did males; although males smoked more cigarettes and drunk more alcohol. However, females consumed more fast food and deep fries and rated public hospitals and sexual and reproductive health services as less good than did males. The findings call for further research on the health of young people living in Mauritius with respect to socio-economic variables in order to promote social justice in the Mauritian society. In addition, this article also emphasises on the need of having a new National Youth Policy for Mauritius, which is long overdue.

Descriptive and multivariate analyses were performed to investigate the effect of the main exposure variable of interest (distance to the nearest IWT on various health outcome measures. Participants living within 1.4 km of an IWT had worse sleep, were sleepier during the day, and had worse SF36 Mental Component Scores compared to those living further than 1.4 km away. Significant dose-response relationships between PSQI, ESS, SF36 Mental Component Score, and log-distance to the nearest IWT were identified after controlling for gender, age, and household clustering. The adverse event reports of sleep disturbance and ill health by those living close to IWTs are supported.

    2017-10-01

    Full Text Available Turmeric, a spice that has long been recognized for its medicinal properties, has received interest from both the medical/scientific world and from culinary enthusiasts, as it is the major source of the polyphenol curcumin. It aids in the management of oxidative and inflammatory conditions, metabolic syndrome, arthritis, anxiety, and hyperlipidemia. It may also help in the management of exercise-induced inflammation and muscle soreness, thus enhancing recovery and performance in active people. In addition, a relatively low dose of the complex can provide health benefits for people that do not have diagnosed health conditions. Most of these benefits can be attributed to its antioxidant and anti-inflammatory effects. Ingesting curcumin by itself does not lead to the associated health benefits due to its poor bioavailability, which appears to be primarily due to poor absorption, rapid metabolism, and rapid elimination. There are several components that can increase bioavailability. For example, piperine is the major active component of black pepper and, when combined in a complex with curcumin, has been shown to increase bioavailability by 2000%. Curcumin combined with enhancing agents provides multiple health benefits. The purpose of this review is to provide a brief overview of the plethora of research regarding the health benefits of curcumin.

    Appropriate oral health care is fundamental for any individual's health. Dental caries is still one of the major public health problems. The most effective way of caries prevention is the use of fluoride. The aim of our research was to review the literature about fluoride toxicity and to inform physicians, dentists and public health specialists whether fluoride use is expedient and safe. Data we used in our review were systematically searched and collected from web pages and documents published from different international institutions. Fluoride occurs naturally in our environment but we consume it in small amounts. Exposure can occur through dietary intake, respiration and fluoride supplements. The most important factor for fluoride presence in alimentation is fluoridated water. Methods, which led to greater fluoride exposure and lowered caries prevalence, are considered to be one of the greatest accomplishments in the 20th century`s public dental health. During pregnancy, the placenta acts as a barrier. The fluoride, therefore, crosses the placenta in low concentrations. Fluoride can be transmitted through the plasma into the mother's milk; however, the concentration is low. The most important action of fluoride is topical, when it is present in the saliva in the appropriate concentration. The most important effect of fluoride on caries incidence is through its role in the process of remineralization and demineralization of tooth enamel. Acute toxicity can occur after ingesting one or more doses of fluoride over a short time period which then leads to poisoning. Today, poisoning is mainly due to unsupervised ingestion of products for dental and oral hygiene and over-fluoridated water. Even though fluoride can be toxic in extremely high concentrations, it`s topical use is safe. The European Academy of Paediatric Dentistry (EAPD) recommends a preventive topical use of fluoride supplements because of their cariostatic effect.

    Air pollution is a widespread health problem associated with respiratory symptoms. Continuous exposure monitoring was performed to estimate alveolar and tracheobronchial dose, measured as deposited surface area, for 103 children and to evaluate the long-term effects of exposure to airborne particles through spirometry, skin prick tests and measurement of exhaled nitric oxide (eNO). The mean daily alveolar deposited surface area dose received by children was 1.35 × 10 3 mm 2 . The lowest and highest particle number concentrations were found during sleeping and eating time. A significant negative association was found between changes in pulmonary function tests and individual dose estimates. Significant differences were found for asthmatics, children with allergic rhinitis and sensitive to allergens compared to healthy subjects for eNO. Variation is a child's activity over time appeared to have a strong impact on respiratory outcomes, which indicates that personal monitoring is vital for assessing the expected health effects of exposure to particles. -- Highlights: •Particle dose was estimated through personal monitoring on more than 100 children. •We focused on real-time daily dose of particle alveolar deposited surface area. •Spirometry, skin prick and exhaled Nitric Oxide tests were performed. •Negative link was found between changes in pulmonary functions and individual doses. •A child's lifestyle appeared to have a strong impact on health respiratory outcomes. -- The respiratory health effects of daily airborne particle dose on children through personal monitoring

    This document gathers Power Point presentations. After a presentation of the new public portal of the French national network of measurements of radioactivity in the environment, a first session addressed the control of the environment by the different actors present on a territory (associations like CLI or ACRO or ATMO, operators like Areva). The addressed issues have been: the control performed by a CLI (Paluel-Penly) with the support of a departmental laboratory, the radiological monitoring of the environment about the Brennilis site, the study of an environmental marker (tritium in hive products), the specific study of the Durance region, the control of ambient radioactivity on the Nord-Pas-de-Calais coast, and the monitoring of the environment by the operator around La Hague site. The second session addressed the building up of reference radiological assessments: lessons learned from radiological assessments implemented by the IRSN, a citizen mapping of radioactivity in France, and improvement orientations for the monitoring of the environment by different actors. The third session addressed issues spanning from the environment to health: assessment of doses based on the control of the environment, global health impact for a set of nuclear power plants, assessment of the health impact of releases, knowledge status on the effects of low doses, and possible improvements of knowledge on the effects of radioactivity on health

    Micronutrients, vitamins and minerals accessible from the diet, are essential for biologic activity. Micronutrient status varies widely throughout pregnancy and across populations. Women in low-income countries often enter pregnancy malnourished, and the demands of gestation can exacerbate micronutrient deficiencies with health consequences to the fetus. Examples of efficacious single micronutrient interventions include folic acid to prevent neural tube defects, iodine to prevent cretinism, zinc to reduce of preterm birth, and iron to reduce the risk of low birth weight. Folic acid and vitamin D might also increase birth weight. While extensive mechanism and association research links antenatal multiple micronutrients to plausible materno-fetal health advantages, hypothesized benefits have often been absent, minimal or unexpected in trials. These findings suggest a role for population context in determining health responses and extensive gaps in knowledge. Multiple micronutrient supplements reduce risks of being born low birth weight, small for gestational age or stillborn in undernourished settings, and justify micronutrient interventions with antenatal care. Measurable health effects of gestational micronutrient exposure may persist into childhood but few data exists on potential long-term benefits. In this Review, we discuss micronutrient intake recommendations, risks and consequences of deficiencies, and the effects of interventions with a particular emphasis on offspring. PMID:27032981

    Full Text Available Aims of the Study: This study was carried out to determine the effective factors in environmental health status of grocery stores in the city of Qom (located in the center of Iran. Materials & Methods: In this cross-sectional study, 283 grocery stores from 3 different regions were selected randomly using stratified sampling. Data were gathered through observation, interview, and questionnaire. The questionnaire consisted of two sections: section 1 dealt with some shop managers’ features including the age, educational level, job satisfaction, passing “food and occupational hygiene training courses”, store ownership, duration of employment, and features of stores including their location (Region and environmental health condition. And section 2 dealt with the important aspects of regulations of Article 13. The data analyzed using statistical procedures such as Spearman Rank Correlation and Multivariate Regression Analysis. P-values less than 0.05 were considered as statistically significant. Results: Among the investigated factors, the manager’s educational level had a greater impact on the environmental health conditions of grocery stores. The ownership status of grocery stores, Job satisfaction and passing “food and occupational hygiene training courses” were next in the ranking, respectively (p <0.001 for all measures, except for shop ownership, for which p-value was <0.02. Conclusions: Planning and implementation of effective operational and strategic programs addressing the above mentioned issues seems to be necessary. Such programs will improve the health status of the stores over time.

  8. Effects of Dietary Fiber and Its Components on Metabolic Health

    Full Text Available Dietary fiber and whole grains contain a unique blend of bioactive components including resistant starches, vitamins, minerals, phytochemicals and antioxidants. As a result, research regarding their potential health benefits has received considerable attention in the last several decades. Epidemiological and clinical studies demonstrate that intake of dietary fiber and whole grain is inversely related to obesity, type two diabetes, cancer and cardiovascular disease (CVD. Defining dietary fiber is a divergent process and is dependent on both nutrition and analytical concepts. The most common and accepted definition is based on nutritional physiology. Generally speaking, dietary fiber is the edible parts of plants, or similar carbohydrates, that are resistant to digestion and absorption in the small intestine. Dietary fiber can be separated into many different fractions. Recent research has begun to isolate these components and determine if increasing their levels in a diet is beneficial to human health. These fractions include arabinoxylan, inulin, pectin, bran, cellulose, β-glucan and resistant starch. The study of these components may give us a better understanding of how and why dietary fiber may decrease the risk for certain diseases. The mechanisms behind the reported effects of dietary fiber on metabolic health are not well established. It is speculated to be a result of changes in intestinal viscosity, nutrient absorption, rate of passage, production of short chain fatty acids and production of gut hormones. Given the inconsistencies reported between studies this review will examine the most up to date data concerning dietary fiber and its effects on metabolic health.

    The question of health effects related to exposures from non-ionizing and non-optical electromagnetic fields is currently concentrated in two frequency ranges: extremely low frequency (ELF) electric and magnetic fields, mainly at the overhead high-voltage power line frequencies of 50/60 Hz, and radiofrequency (RF) radiation, encompassing the frequency range from a few kilohertz to 300 GHz. The part between 300 MHz and 300 GHz is also usually named microwaves (MW); from this point of view, microwaves are part of the whole RF spectrum. The following brief overview is aimed at evaluating the state of knowledge regarding the question of health effects associated to exposures to ELF and RF/MW fields

    Building occupants are exposed to manufactured chemicals. Exposure in the indoor environment can occur via non-dietary ingestion (e.g. indoor dust), inhalation and dermal absorption including dermal uptake directly from air. The extent of dermal uptake from air has been previously studied...... for volatile organic compounds (VOC). Not much is however known about its role for semivolatile organics (SVOC) and therefore this exposure pathway is often neglected in exposure assessments. Dermal uptake received attention with regards to contact transfer from contaminated surfaces. Recent modeling efforts...... intake from inhalation.

    2010-04-01

    Youth spend an average of >7 hours/day using media, and the vast majority of them have access to a bedroom television, computer, the Internet, a video-game console, and a cell phone. In this article we review the most recent research on the effects of media on the health and well-being of children and adolescents. Studies have shown that media can provide information about safe health practices and can foster social connectedness. However, recent evidence raises concerns about media's effects on aggression, sexual behavior, substance use, disordered eating, and academic difficulties. We provide recommendations for parents, practitioners, the media, and policy makers, among others, for ways to increase the benefits and reduce the harm that media can have for the developing child and for adolescents.

    2017-09-12

    The deleterious effects of ambient air pollution on human health have been consistently documented by many epidemiologic studies worldwide, and it has been calculated that globally at least seven million deaths are annually attributable to the effects of air pollution. The major air pollutants emitted into the atmosphere by a number of natural processes and human activities include nitrogen oxides, volatile organic compounds, and particulate matter. In addition to the poor ambient air quality, there is increasing evidence that indoor air pollution also poses a serious threat to human health, especially in low-income countries that still use biomass fuels as an energy resource. This review summarizes the current knowledge on ambient air pollution in financially deprived populations.

    Kombucha is a slightly sweet, slightly acidic tea beverage consumed worldwide, but historically in China, Russia, and Germany. Kombucha is prepared by fermenting sweetened black tea preparations with a symbiotic culture of yeasts and bacteria. Potential health effects have created an increased interest in Kombucha. Yet, only a few research studies have shown that Kombucha has in vitro antimicrobial activity and enhances sleep and pain thresholds in rats. Furthermore, Kombucha consumption has proven to be harmful in several documented instances.

    Due to poor design, operator error and the absence of an established {sup S}afety Culture{sup ,} the worst accident in the history of nuclear power involving the Unit 4 RMBK reactor occurred at Chernobyl in the Ukraine in the early morning of 26 April 1986. This accident led to the contamination of large tracts of forest and agricultural land (in the former Soviet Union) and the evacuation of a large number of people. Thirty-one people died at the time of the accident or shortly afterwards, and 203 people were treated for the Acute Radiation Syndrome. From about 1990 a significant increase in the number of childhood thyroid cancers has been noted in Belarus and Ukraine. Because of the social, political and economic situation in the Soviet Union soon after the accident, the anxiety and stress induced in the general population has been enhanced to the point where it may well be the single most important indirect health effect of the accident. Contamination outside the former Soviet Union was largely confined to Europe, where it was extremely patchy and variable. Contamination in the rest of the Northern Hemisphere was insignificant. The health effects in the General Population in the Contaminated Regions in the former USSR and Europe, are predicted to be low and not discernible. However, there may be subgroups within, for example, the Liquidators, which if they can be identified and followed, may show adverse health effects. Health effects in the rest of the Northern Hemisphere will be inconsequential. (author) 38 refs., 1 tab., 1 fig.

    2008-01-01

    The extended regulatory interests in severe accidents management and enhanced safety regulatory requirements raise a need of more accurate analysis of the effect to the public health by users with diverse disciplines. This facilitates this work to develop web-based radiation health effect assessment software, RASUM, by using the MACCS2 code and HTML language to provide diverse users (regulators, operators, and public) with easy understanding, modeling, calculating, analyzing, documenting and reporting of the radiation health effect under hypothetical severe accidents. The engine of the web-based RASUM uses the MACCS2 as a base code developed by NRC and is composed of five modules such as development module, PSA training module, output module, input data module (source term, population distribution, meteorological data, etc.), and MACCS2 run module. For verification and demonstration of the RASUM, the offsite consequence analysis using the RASUM frame is performed for such as early fatality risk, organ does, and whole body does for two selected scenarios. Moreover, CCDF results from the RASUM for KSNP and CANDU type reactors are presented and compared. (author)

    2008-01-01

    Full text: A controversy still persists on whether health effects can be alleged from radiation exposure situations involving low radiation doses (e.g. below the international dose limits for the public). Arguments have evolved around the validity of the dose-response representation that is internationally used for radiation protection purposes, namely the so-called linear-non-threshold (LNT) model. The debate has been masked by the intrinsic randomness of radiation interaction at the cellular level and also by gaps in the relevant scientific knowledge on the development and expression of health effects. There has also been a vague use, abuse, and misuse of radiation-related risk concepts and quantities and their associated uncertainties. As a result, there is some ambiguity in the interpretation of the phenomena and a general lack of awareness of the implications for a number of risk-causation qualities, namely its attributes and characteristics. In particular, the LNT model has been used not only for protection purposes but also for blindly attributing actual effects to specific exposure situations. The latter has been discouraged as being a misuse of the model, but the supposed incorrectness has not been clearly proven. The paper will endeavour to demonstrate unambiguously the following thesis in relation to health effects due to low radiation doses: 1) Their existence is highly plausible. A number of epidemiological statistical assessments of sufficiently large exposed populations show that, under certain conditions, the prevalence of the effects increases with dose. From these assessments, it can be hypothesized that the occurrence of the effects at any dose, however small, appears decidedly worthy of belief. While strictly the evidence does not allow to conclude that a threshold dose level does not exist either.

    1986-08-01

    On March 28, 1979, the Unit 2 reactor at the Three Mile Island (TMI) Nuclear Station was severely damaged by an accident. Radioactivity was discharged to the environment resulting in a small amount of radiation exposure to the public. Continuing concerns by some members of the communities around TMI about the potential radiation-induced health effects prompted GPU Nuclear Corporation to examine the information gathered from the accident investigation in the context of our current knowledge of radiation and its effects on human health. Although this report deals with technical matters, the information is presented in a manner that can be understood by those who do not have scientific backgrounds. This report is divided into three major sections. The first section provides an overview of the past 80 years of relevant research on the subject of radiation and its effects on human health. During that time, scientists and physicians throughout the world have studied hundreds of thousands of individuals exposed to radiation from medical and occupational sources and from nuclear weapons explosions. Epidemiologic studies of humans, such as the Japanese survivors of the atomic bomb, have established that following exposure to large doses of radiation, certain health effects, including cancer, can be observed. Radiation-induced health effects from low doses of radiation, such as those associated with the TMI-2 accident, appear infrequently, if at all, and are identical and, therefore, indistinguishable from similar health effects which occur normally. For example, cancers induced by radiation are indistinguishable from those occurring spontaneously or normally. It is not possible, therefore, for scientists to determine directly whether radiation-induced health effects at low doses occur at all; such observations can only be inferred by statistical methods. The second section of this report provides a brief description of the TMI-2 accident. Most of the radioactivity from the

    This research is an examination of the effects of racial discrimination and health-promoting behaviors on the physical and mental health of a sample of 399 well-educated African American men. One would think that the attainment of higher education would increase health-promoting behaviors and might decrease discriminatory experiences that impact health. However, regression analysis indicated a more complex picture. Health-promoting behaviors were positively related to mental health, whereas experiences of racial discrimination contributed to poorer mental health. Relationships between health-promoting behaviors and that of racial discrimination to physical health were found to be nonsignificant. In conclusion, the authors discuss the importance of culturally appropriate health-promotion efforts.

    Quantal health effects caused by the combined action of a number of toxic agents are modeled using the information available for each toxicant acting in isolation. Two basic models are used; one assumes no interaction, the other postulates a separable kind of interaction in which each agent contributes an enhancement factor independent of all other agents. These two models provide yardsticks by which to measure synergisms and antagonisms in the interaction between the effects of toxic agents.

    Full Text Available Introduction: Millions of Muslims across the world observe Islamic fasting during the holy month of Ramadan, as well as the other specific dates in the lunar calendar year. While fasting during this month, Muslims refrain from eating or drinking from dawn to dusk. Islamic fasting is similar to alternate day fasting (ADF since it incorporates an average of 12 hours of fasting and 12 hours of feasting periods. This present review study is aimed to find out the common adverse health effects associated with Islamic fasting and the preventive measures to be followed to avoid them. Methods: The literature was reviewed through searching in databases such as PubMed, Google Scholar, and reference lists to identify the related articles. Results: Many health benefits have been attributed to Islamic fasting, including the reduced risk of cardiovascular diseases, diabetes, cancer, hypertension, and asthma. On the other hand, some studies have mentioned a few health problems associated with Islamic fasting, such as headaches, heartburn, constipation, dehydration, decreased sleep quality, and anemia, which may occur in some fasting individuals during Ramadan. Conclusion: Islamic fasting could be beneficial for health if it is performed correctly. During Ramadan, fasting individuals are advised to adhere to a balanced diet that contains sufficient portions of fruits and vegetables, whole grains, pulses, meat, fish, milk, and dairy products. Moreover, fasting individuals must drink adequate fluids, such as water, fresh fruit juices, and soups, in order to prevent the possible adverse health effects associated with Islamic fasting.

    The public health consequences of the legalization of marijuana, whether for medical or recreational purposes, are little understood. Despite this, numerous states are considering medical or recreational legalization. In the context of abrupt changes in marijuana policy in 2009 in Colorado, the authors sought to investigate corresponding changes in marijuana-related public health indicators. This observational, ecologic study used an interrupted time-series analysis to identify changes in public health indicators potentially related to broad policy changes that occurred in 2009. This was records-based research from the state of Colorado and Denver metropolitan area. Data were collected to examine frequency and trends of marijuana-related outcomes in hospital discharges and poison center calls between time periods before and after 2009 and adjusted for population. Analyses were conducted in 2014. Hospital discharges coded as marijuana-dependent increased 1% per month (95% CI=0.8, 1.1, pcenter calls mentioning marijuana (pcenter calls increased 0.8% per month (95% CI=0.2, 1.4, pcenter calls also increased 56% (95% CI=49%, 63%, p<0.001) in the period following the policy change. Further, there was one hospital discharge coded as dependent for every 3,159 (95% CI=2465, 3853, p<0.001) medical marijuana registrant applications. The abrupt nature of these changes suggests public health effects related to broad policy changes associated with marijuana. This report may be used to assist in policy decisions regarding the short-term public health effects of marijuana legalization. Copyright © 2016 American Journal of Preventive Medicine.

    Atypical work schedules cause reduced sleep, leading to drowsiness, fatigue, decline of cognitive performance and health problems among the members of the nursing staff. The study was aimed at reviewing current knowledge and attitudes concerning the impact of sleep disorders on health and cognitive functions among the members of the nursing staff. Sleep and Interpersonal Relations in Modern Society. The modern 24-hour society involves more and more employees (health services, police departments, public transport) in non-standard forms of work. In European Union countries, over 50% of the nursing staff work night shifts, while in the United States of America 55% of nursing staff work more than 40 hours a week, and 30-70% of nurses sleep less than six hours before their shift. Cognitive Effects of Sleep Deprivation. Sleep deprivation impairs the performance of tasks that require intensive and prolonged attention which increases the number of errors in patients care, and nurses are subject to incre- ased risk of traffic accidents. Sleep Deprivation and Health Disorders. Sleep deprived members of the nursing staff are at risk of obesity, diabetes, gastrointestinal disorders and cardiovascular disease. The risk factors for breast cancer are increased by 1.79 times. and there is a significantly higher risk for colorectal carcinoma. Too long or repeated shifts reduce the opportunity for sleep, shorten recovery time in nurses, thus endangering their safety and health as well as the quality of care and patients' safety. Bearing in mind the significance of the problerm it is necessary to conduct the surveys of sleep quality and health of nurses in the Republic of Serbia as well in order to tackle this issue which is insufficiently recognized.

    This article presents the results of a multidisciplinary study which investigated the effects of a period with floorball training on health status, psychological health and social capital of older men. Thirty-nine untrained men aged 69.9 ± 0.6 (range: 65-76) were randomized into a group playing floorball (n = 22) or a group playing petanque (n = 17) one hour twice a week for 12 weeks. Both groups filled out the Health Survey Short Form (SF-12) and the Hospital Anxiety and Depression Scale (HADS) before and after the 12-week intervention. Linear regression analyses with bootstrapping showed that the men in the floorball group improved in the SF-12 composite score for mental health, as well as the HADS subscales anxiety and depression, compared to the men in the petanque group. In addition, 21 interviews were conducted with a sample of the men engaged in floorball. According to the statements in the interviews, the men in the floorball group experienced a high degree of solidarity and group cohesion which seemed to have increased their social capital during the intervention. In particular, the fun and joyful experiences of playing led to a high degree of social connectedness, which were mentioned by many of the men as the main reason for their participation throughout the 12-week period. The statistical results and the interview findings suggest that participation in a ball game such as floorball has several benefits regarding health status, psychological health and social capital and in addition that playing floorball is experienced as enjoyable amongst older men. Thus, it can be concluded that floorball is an activity that benefits older men and should be provided in relevant contexts, such as e.g. sport clubs or centres for seniors.

    There are a large number of workers in the United States, spanning a variety of occupational industries and sectors, who are potentially exposed to chemicals that can be absorbed through the skin. Occupational skin exposures can result in numerous diseases that can adversely affect an individual's health and capacity to perform at work. In general, there are three types of chemical-skin interactions of concern: direct skin effects, immune-mediated skin effects, and systemic effects. While hundreds of chemicals (metals, epoxy and acrylic resins, rubber additives, and chemical intermediates) present in virtually every industry have been identified to cause direct and immune-mediated effects such as contact dermatitis or urticaria, less is known about the number and types of chemicals contributing to systemic effects. In an attempt to raise awareness, skin notation assignments communicate the potential for dermal absorption; however, there is a need for standardization among agencies to communicate an accurate description of occupational hazards. Studies have suggested that exposure to complex mixtures, excessive hand washing, use of hand sanitizers, high frequency of wet work, and environmental or other factors may enhance penetration and stimulate other biological responses altering the outcomes of dermal chemical exposure. Understanding the hazards of dermal exposure is essential for the proper implementation of protective measures to ensure worker safety and health.

    Greenhouse gases are driving climate change. This article explores the adverse health effects of climate change on a particularly vulnerable population: children and adults with respiratory conditions. This review provides a general overview of the effects of increasing temperatures, extreme weather, desertification, and flooding on asthma, chronic obstructive lung disease, and respiratory infections. We offer suggestions for future research to better understand climate change hazards, policies to support prevention and mitigation efforts targeting climate change, and clinical actions to reduce individual risk. Climate change produces a number of changes to the natural and built environments that may potentially increase respiratory disease prevalence, morbidity, and mortality. Nurses might consider focusing their research efforts on reducing the effects of greenhouse gases and in directing policy to mitigate the harmful effects of climate change. Nurses can also continue to direct educational and clinical actions to reduce risks for all populations, but most importantly, for our most vulnerable groups. While advancements have been made in understanding the impact of climate change on respiratory health, nurses can play an important role in reducing the deleterious effects of climate change. This will require a multipronged approach of research, policy, and clinical action. © 2017 Sigma Theta Tau International.

    Twenty years have passed since the worst nuclear reactor accident in the world occurred at the Chernobyl nuclear power plant in Ukraine. The radioactive contamination which resulted from the explosion and fire in the first few days spread over large areas of neighbouring Belarus and the Russian Federation, with most of the fallout in Belarus. While national and local authorities did not immediately disclose the scale of the accident, the mitigation measures, such as distribution of potassium iodine pills, food restriction, and mass evacuation from areas where the radioactive contamination was greatest, undoubtedly reduced the health impact of the radiation exposure and saved many lives. The accident caused severe social and economic disruption and had significant environmental and health impact. This was aggravated by the political and economical changes in the three affected states related to the break-down of the Soviet Union. In the aftermath of the accident the international scientific and medical community collaborated closely with national experts dealing with health effects of the accident in the affected countries. There is a substantial body of international collaborative projects on the situation, which should lead to advancement in radiation sciences. However, considerable speculation and disinformation remains about the possible health impact of the accident for the millions of affected people. To address the health, environmental and socioeconomic consequences of the Chernobyl accident, the United Nations in 2003 launched an Inter-Agency initiative, the Chernobyl Forum. The Forum's Secretariat, led by the International Atomic Energy Agency (IAEA), the World Health Organization (WHO), the United Nations Development Programme (UNDP), and several other international organizations collaborated with the governments of the affected countries. The purpose of the Chernobyl Forum was to review the consequences of the accident, issue technical reports and, based

    The major healt effect of the accident at Three Mile Island was that of a pronounced demoralizing effect on the general population living in the Three Mile Island area, including teenagers and mothers of preschool children, and the nuclear plant workers. However, this effect has proved transient in all groups studied except the nuclear workers, who continued to show relatively high levels of demoralization some months after the accident. Moreover, the groups in the general population and the workers, in their differen ways, had continuing problems of trust that stemmed directly from the Three Mile Island accident. For both the nuclear workers and general population, the mental health and behavioral effects are understandable in terms of the objective realities of the threats they faced during the nuclear accident at Three Mile Island

    Scientific and technological developments bring unprecedented stress to our environment. Society has to predict the results of potential health risks from technologically based actions that may have serious, far-reaching consequences. The potential for error in making such predictions or assessment is great and multiplies with the increasing size and complexity of the problem being studied. Because of this, the availability and use of reliable data is the key to any successful forecasting effort. Scientific research and development generate new data and information. Much of the scientific data being produced daily is stored in computers for subsequent analysis. This situation provides both an invaluable resource and an enormous challenge. With large amounts of government funds being devoted to health and environmental research programs and with maintenance of our living environment at stake, we must make maximum use of the resulting data to forecast and avert catastrophic effects. Along with the readily available. The most efficient means of obtaining the data necessary for assessing the health effects of chemicals is to utilize applications include the toxicology databases and information files developed at ORNL. To make most efficient use of the data/information that has already been prepared, attention and resources should be directed toward projects that meticulously evaluate the available data/information and create specialized peer-reviewed value-added databases. Such projects include the National Library of Medicine`s Hazardous Substances Data Bank, and the U.S. Air Force Installation Restoration Toxicology Guide. These and similar value-added toxicology databases were developed at ORNL and are being maintained and updated. These databases and supporting information files, as well as some data evaluation techniques are discussed in this paper with special focus on how they are used to assess potential health effects of environmental agents. 19 refs., 5 tabs.

    To better understand the role of the professional oral health care for elderly in improving geriatric oral health, the effects of short-term professional oral health care (once per week for 1 month) on oral microbiological parameters were assessed. Parallel, open-labelled, randomize-controlled trial was undertaken in a nursing home for elderly in Shizuoka, Japan. Thirty-four dentate elderly over 74 years were randomly assigned from ID number to the intervention (17/34) and control (17/34) groups. The outcomes were changes in oral microbiological parameters (number of bacteria in unstimulated saliva; whole bacteria, Streptococcus, Fusobacterium and Prevotella: opportunistic pathogens detection: and index of oral hygiene evaluation [Dental Plaque Index, DPI]) within the intervention period. Each parameter was evaluated at before and after intervention period. Four elderly were lost from mortality (1), bone fracture (1), refused to participate (1) and multi-antibiotics usage (1). Finally, 30 elderly were analysed (14/intervention and 16/control). At baseline, no difference was found between the control and intervention groups. After the intervention period, the percentage of Streptococcus species increased significantly in the intervention group (Intervention, 86% [12/14]; Control, 50% [8/16]: Fisher's, right-tailed, P oral health care can improve oral conditions in the elderly. © 2014 John Wiley & Sons A/S.

    Objectives I examined the relationship between paid maternity leave and maternal mental health among women returning to work within 12 weeks of childbirth, after 12 weeks, and those returning specifically to full-time work within 12 weeks of giving birth. Methods I used data from 3850 women who worked full-time before childbirth from the Early Childhood Longitudinal Study-Birth Cohort. I utilized propensity score matching techniques to address selection bias. Mental health was measured using the Center for Epidemiologic Studies Depression (CESD) scale, with high scores indicating greater depressive symptoms. Results Returning to work after giving birth provided psychological benefits to women who used to work full-time before childbirth. The average CESD score of women who returned to work was 0.15 standard deviation (p leave, on the other hand, was associated with adverse effects on mental health. The average CESD score of women who returned within 12 weeks of giving birth was 0.13 standard deviation higher (p leave was associated with an improved mental health outcome. Among all women who returned to work within 12 weeks of childbirth, those women who received some paid leave had a 0.17 standard deviation (p leave.

    To understand and document children's stated experiences and beliefs about television and to elicit their suggestions for alternative activities. Eleven focus groups were conducted with 51 Anglo and Latino children, ages 7-10, in a large Northern California city. Philosophical underpinnings of developmental psychology were the basis for multiphase thematic analysis. Data were collected in 1998-1999. Themes were identified in five conceptual categories. Findings showed that children did not perceive many parental rules related to TV watching, rather daily routines are associated with TV viewing. Children revealed both covert and overt motivations for watching. Nearly all participants spoke of the deception of advertising, but they were unclear about the role of commercial sponsors in payment for TV shows. Children perceived both negative physical and behavioral health effects of TV and they had great difficulty imagining life without a TV. Children perceived television as providing educational and relational needs. Although they preferred alternatives to TV, they had difficulty articulating and getting those needs met. Clinicians and researchers can utilize these findings to design health interventions that attenuate the health-impairing effects of habitual sedentary activity in childhood.

    1979-04-01

    It is now assumed that any exposure to radiaton at low levels of dose carries some risk of deleterious effects. How low this level may be, or the probability or magnitude of the risk, still are not known. Our best scientific knowledge and advice are essential for the protection of the public health, for the effective application of new technologies in medicine and industry and for guidance in the production of nuclear energy. Unless man wishes to dispense with those activities which inevitably involve exposure to low levels of ionizing radiations, he must recognize that some degree of risk to health, however small, exists. A pragmatic appraisal of how man wishes to continue to derive the benefits of health and happiness from such activities involving ionizing radiaton in times of everchanging conditions and public attitudes in our resource-limited society is the task which lies before all of us - all men and women of our society, of science and of medicine, and of law and government - now and in the future

    The number of residential wood burning devices has increased in Denmark during the latest years and it has been estimated that there in 2005 were about 551,000 wood stoves and about 48,000 wood boilers in Denmark. This has resulted in an increased exposure of the general Danish population to pollutants associated with residential wood smoke. New Danish monitoring results on particulate matter (PM) in ambient air have shown elevated PM levels in areas with many wood stoves, particularly during wintertime when wood burning is common. Due to the size distribution of wood smoke particles essentially all will be contained in the PM{sub 2.5} fraction. It has been estimated that about 17,665 tonnes PM{sub 2.5} per year (2005) in Denmark come from residential wood combustion. Therefore, there is an increasing concern that adverse human health effects might be associated with the increased exposure to residential wood smoke. This project has been set up in order to review the scientific literature concerning adverse health effects of pollutants associated with residential wood smoke with the main focus on particulate matter and to quantify and evaluate, if possible, the impact on human health of the increased exposure to particles in residential wood smoke.

    The impact of climate change through global warming has been a concern for some time now. Targets are being set for ratifying countries to reduce their CO{sup 2} emissions. In order to achieve reduction in CO{sup 2} emissions, there must be sustained move in the production of electricity from renewable sources other than fossil fuel combustion. Of the renewable energy sources, the most realistic and economic is Wind Power. The Asian continent is developing into one of the main powerhouses of Wind Energy. The strongest market leader in Wind Energy in the continent is India. On the flip side, there are some effects of Wind Turbines which are hazardous to human health like noise generated. Such hazards are also likely and known to affect the migratory birds during transition. This paper will address the effects of Wind Turbine on Human Health and Environment. The paper will focus on the following questions: (1)What are the potential health and environmental impacts of Wind Turbines? (2)How is exposure to Wind Turbine Noise assessed? (3)What consultation process with the community is required before Wind Farms are constructed? (Author)

    Health professionals increasingly use social media to communicate health information, but it is unknown how visual message presentation on these platforms affects message reception. This study used an experiment to analyse how young adults (n = 839) perceive sexual health messages on Instagram. Participants were exposed to one of four conditions based on visual message presentation. Messages with embedded health content had the highest perceived message effectiveness ratings. Additionally, message sensation value, attitudes and systematic information processing were significant predictors of perceived message effectiveness. Implications for visual message design for electronic health are discussed.

    To examine risk and resilience factors that affect health, lifetime stress exposure histories, dispositional forgiveness levels, and mental and physical health were assessed in 148 young adults. Greater lifetime stress severity and lower levels of forgiveness each uniquely predicted worse mental and physical health. Analyses also revealed a graded Stress × Forgiveness interaction effect, wherein associations between stress and mental health were weaker for persons exhibiting more forgiveness. These data are the first to elucidate the interactive effects of cumulative stress severity and forgiveness on health, and suggest that developing a more forgiving coping style may help minimize stress-related disorders. © The Author(s) 2014.

  12. The health effects of low-dose ionizing radiation

    2012-01-01

    It has been established by various researches, that high doses of ionizing radiation are harmful to health. There is substantial controversy regarding the effects of low doses of ionizing radiation despite the large amount of work carried out (both laboratory and epidemiological). Exposure to high levels of radiation can cause radiation injury, and these injuries can be relatively severe with sufficiently high radiation doses. Prolonged exposure to low levels of radiation may lead to cancer, although the nature of our response to very low radiation levels is not well known at this time. Many of our radiation safety regulations and procedures are designed to protect the health of those exposed to radiation occupationally or as members of the public. According to the linear no-threshold (LNT) hypothesis, any amount, however small, of radiation is potentially harmful, even down to zero levels. The threshold hypothesis, on the other hand, emphasizes that below a certain threshold level of radiation exposure, any deleterious effects are absent. At the same time, there are strong arguments, both experimental and epidemiological, which support the radiation hormesis (beneficial effects of low-level ionizing radiation). These effects cannot be anticipated by extrapolating from harmful effects noted at high doses. Evidence indicates an inverse relationship between chronic low-dose radiation levels and cancer incidence and/or mortality rates. Examples are drawn from: 1) state surveys for more than 200 million people in the United States; 2) state cancer hospitals for 200 million people in India; 3) 10,000 residents of Taipei who lived in cobalt-60 contaminated homes; 4) high-radiation areas of Ramsar, Iran; 5) 12 million person-years of exposed and carefully selected control nuclear workers; 6) almost 300,000 radon measurements of homes in the United States; and 7) non-smokers in high-radon areas of early Saxony, Germany. This evidence conforms to the hypothesis that

    Human beings are exposed to natural radiation from external sources include radionuclides in the earth and cosmic radiation, and by internal radiation from radionuclides, mainly uranium and thorium series, incorporated into the body. Living systems have adapted to the natural levels of radiation and radioactivity. But some industrial practices involving natural resources enhance these radionuclides to a degree that they may pose risk to humans and the environment if they are not controlled. Biological effects of ionizing radiation are the outcomes of physical and chemical processes that occur immediately after the exposure, then followed by biological process in the body. These processes will involve successive changes in the molecular, cellular, tissue and whole organism levels. Any dose of radiation, no matter how small, may produce health effects since even a single ionizing event can result in DNA damage. The damage to DNA in the nucleus is considered to be the main initiating event by which radiation causes damage to cells that results in the development of cancer and hereditary disease. It has also been indicated that cytogenetic damage can occur in cells that receive no direct radiation exposure, known as bystander effects. This paper reviews health risks of low dose radiation exposure to human body causing stochastic effects, i.e. cancer induction in somatic cells and hereditary disease in genetic cells. (author)

    Certain marine algae produce potent toxins that impact human health through the consumption of contaminated shellfish and finfish and through water or aerosol exposure. Over the past three decades, the frequency and global distribution of toxic algal incidents appear to have increased, and human intoxications from novel algal sources have occurred. This increase is of particular concern, since it parallels recent evidence of large-scale ecologic disturbances that coincide with trends in global warming. The extent to which human activities have contributed to their increase therefore comes into question. This review summarizes the origins and health effects of marine algal toxins, as well as changes in their current global distribution, and examines possible causes for the recent increase in their occurrence.

    In contemporary Japan, there is a polarizing trend in children who exercise more than 1,800 minutes a week and those who exercise less than 60 minutes a week. Quite a lot of girls in particular hate exercise,and therefore they don't get enough of it. Osteoporosis is a preventable disease from childhood. It is crucial for girls to exercise and to provide appropriate stimulation to bones before menarche, which increases bone mineral content. Exercise and sports in childhood are characterized as the ways to the lifelong prevention strategies against osteoporosis and fractures. It is hoped that all children practice appropriate exercise program based on scientific evidence to promote bone health. In this review article, the effects of exercising in childhood on bone health, and the points to be noted regarding childhood sports are described.

    We estimated the effects of high incarceration rates on rates of sexually transmitted infections and teenage pregnancies. We calculated correlations between rates of incarceration in state prisons and county jails and rates of sexually transmitted infections and teenage pregnancies for each of the 100 counties in North Carolina during 1995 to 2002. We also estimated increases in negative health outcomes associated with increases in incarceration rates using negative binomial regression analyses. Rates of sexually transmitted infections and teenage pregnancies, adjusted for age, race, and poverty distributions by county, consistently increased with increasing incarceration rates. In the most extreme case, teenage pregnancies exhibited an increase of 71.61 per 100000 population (95% confidence interval [CI]=41.88, 101.35) in 1996 after an increase in the prison population rate from 223.31 to 468.58 per 100000 population in 1995. High rates of incarceration can have the unintended consequence of destabilizing communities and contributing to adverse health outcomes.

    Climate change will have significant effects on the health of wildlife, domestic animals, and humans, according to scientists. The Intergovernmental Panel on Climate Change projects that unprecedented rates of climate change will result in increasing average global temperatures; rising sea levels; changing global precipitation patterns, including increasing amounts and variability; and increasing midcontinental summer drought (Intergovernmental Panel on Climate Change, 2007). Increasing temperatures, combined with changes in rainfall and humidity, may have significant impacts on wildlife, domestic animal, and human health and diseases. When combined with expanding human populations, these changes could increase demand on limited water resources, lead to more habitat destruction, and provide yet more opportunities for infectious diseases to cross from one species to another.

    In this review, we address significant characteristics of parturition in the pig and their connection to post-partum reproductive health and fertility. We discuss the normal physiology and behaviour around parturition and the effect of the second phase (expulsion of foetuses) on the third phase of parturition (expulsion of foetal membranes). In addition, we intend to cover retained placenta, and the connection to post-partum uterine health and fertility in the contemporary prolific sow. We also explore factors that support successful parturition or can cause potential problems. Successful parturition in the pig includes the possibility to express adequate maternal behaviour, rapid expulsion of the piglets, complete expulsion of the placenta, neonatal activity and colostrum intake. Abnormal incidents during any phase of parturition can cause subsequent problems. Duration of the expulsion phase of foetuses can be used as a simple measure of whether parturition is considered successful. Prolonged parturition can impair health of the sow and piglet and fertility after weaning. New insights, such as adding more fibre to sow diets during pregnancy, and especially during the period prior to farrowing, may prevent constipation, increase water intake of the sow around parturition and increase milk intake and performance of piglets. Maternal characteristics, including maternal behaviour, ease of parturition, colostrum production and piglet quality parameters, may be utilized to improve success rate of reproductive management during farrowing and early lactation. Additionally, we share some of the recent developments in methods, including ultrasonography in evaluation of post-partum uterine health. In conclusion, successful farrowing is of the greatest importance for reproductive health of the sow and survival of the piglets. We suggest connections exist among prolonged farrowing and yield of colostrum, retained placenta, development of PDS, and impaired involution of the

    Full Text Available Adequate nutrition is particularly important during pregnancy since it is needed not only for maintaining the health of the mother, but also determines the course of pregnancy and its outcome, fetus development as well as the child’s health after birth and during the later period of life. Data coming from epidemiological and interventions studies support the observation that carotenoids intake provide positive health effects in adults and the elderly population. These health effects are the result of their antioxidant and anti-inflammatory properties. Recent studies have also demonstrated the significant role of carotenoids during pregnancy and infancy. Some studies indicate a correlation between carotenoid status and lower risk of pregnancy pathologies induced by intensified oxidative stress, but results of these investigations are equivocal. Carotenoids have been well studied in relation to their beneficial role in the prevention of preeclampsia. It is currently hypothesized that carotenoids can play an important role in the prevention of preterm birth and intrauterine growth restriction. Carotenoid status in the newborn depends on the nutritional status of the mother, but little is known about the transfer of carotenoids from the mother to the fetus. Carotenoids are among the few nutrients found in breast milk, in which the levels are determined by the mother’s diet. Nutritional status of the newborn directly depends on its diet. Both mix feeding and artificial feeding may cause depletion of carotenoids since infant formulas contain only trace amounts of these compounds. Carotenoids, particularly lutein and zeaxanthin play a significant role in the development of vision and nervous system (among others, they are important for the development of retina as well as energy metabolism and brain electrical activity.

    Strengthening primary health care (PHC) is considered a priority for efficient and responsive health systems, but empirical evidence from low- and middle-income countries is limited. The stepwise introduction of family medicine across all 81 provinces of Turkey (a middle-income country) between 2005 and 2010, aimed at PHC strengthening, presents a natural experiment for assessing the effect of family medicine on health service utilization and user satisfaction.The effect of health system reforms, that introduced family medicine, on utilization was assessed using longitudinal, province-level data for 12 years and multivariate regression models adjusting for supply-side variables, demographics, socio-economic development and underlying yearly trends. User satisfaction with primary and secondary care services was explored using data from annual Life Satisfaction Surveys. Trends in preferred first point of contact (primary vs secondary, public vs. private), reason for choice and health services issues, were described and stratified by patient characteristics, provider type, and rural/urban settings.Between 2002 and 2013, the average number of PHC consultations increased from 1.75 to 2.83 per person per year. In multivariate models, family medicine introduction was associated with an increase of 0.37 PHC consultations per person (P < 0.001), and slower annual growth in PHC and secondary care consultations. Following family medicine introduction, the growth of PHC and secondary care consultations per person was 0.08 and 0.30, respectively, a year. PHC increased as preferred provider by 9.5% over 7 years with the reasons of proximity and service satisfaction, which increased by 14.9% and 11.8%, respectively. Reporting of poor facility hygiene, difficulty getting an appointment, poor physician behaviour and high costs of health care all declined (P < 0.001) in PHC settings, but remained higher among urban, low-income and working-age populations. © The Author 2016

    Volcanoes pose a threat to almost half a billion people; today there are approximately 500 active volcanoes on Earth, and every year there are 10 to 40 volcanic eruptions. Volcanic eruptions produce hazardous effects for the environment, climate, and the health of the exposed persons, and are associated with the deterioration of social and economic conditions. Along with magma and steam (H2O), the following gases surface in the environment: carbon dioxide (CO2) and sulphur dioxide (SO2), carbon monoxide (CO), hydrogen sulphide (H2S), carbon sulphide (CS), carbon disulfide (CS2), hydrogen chloride (HCl), hydrogen (H2), methane (CH4), hydrogen fluoride (HF), hydrogen bromide (HBr) and various organic compounds, as well as heavy metals (mercury, lead, gold).Their unfavourable effects depend on the distance from a volcano, on magma viscosity, and on gas concentrations. The hazards closer to the volcano include pyroclastic flows, flows of mud, gases and steam, earthquakes, blasts of air, and tsunamis. Among the hazards in distant areas are the effects of toxic volcanic ashes and problems of the respiratory system, eyes and skin, as well as psychological effects, injuries, transport and communication problems, waste disposal and water supplies issues, collapse of buildings and power outage. Further effects are the deterioration of water quality, fewer periods of rain, crop damages, and the destruction of vegetation. During volcanic eruptions and their immediate aftermath, increased respiratory system morbidity has been observed as well as mortality among those affected by volcanic eruptions. Unfavourable health effects could partly be prevented by timely application of safety measures.

    The welfare state is potentially an important macro-level determinant of health that also moderates the extent, and impact, of socio-economic inequalities in exposure to the social determinants of health. The welfare state has three main policy domains: health care, social policy (e.g. social transfers and education) and public health policy. This is the protocol for an umbrella review to examine the latter; its aim is to assess how European welfare states influence the social determinants of health inequalities institutionally through public health policies. A systematic review methodology will be used to identify systematic reviews from high-income countries (including additional EU-28 members) that describe the health and health equity effects of upstream public health interventions. Interventions will focus on primary and secondary prevention policies including fiscal measures, regulation, education, preventative treatment and screening across ten public health domains (tobacco; alcohol; food and nutrition; reproductive health services; the control of infectious diseases; screening; mental health; road traffic injuries; air, land and water pollution; and workplace regulations). Twenty databases will be searched using a pre-determined search strategy to evaluate population-level public health interventions. Understanding the impact of specific public health policy interventions will help to establish causality in terms of the effects of welfare states on population health and health inequalities. The review will document contextual information on how population-level public health interventions are organised, implemented and delivered. This information can be used to identify effective interventions that could be implemented to reduce health inequalities between and within European countries. PROSPERO CRD42016025283.

  9. Good jobs, good pay, better health? The effects of job quality on health among older European workers.

    Using data from the Survey of Health, Ageing and Retirement in Europe, this study presents new evidence on the effects of job quality on the occurrence of severe acute conditions, the level of cardiovascular risk factors, musculoskeletal disorders, mental health, functional disabilities and self-assessed health among workers aged 50+. By combining intrinsic job quality with job insecurity and pay the study maps out multiple potential pathways through which work may affect health and well-being. Levering longitudinal data and external information on early retirement ages allows for accounting of unobserved heterogeneity, selection bias and reverse causality. The empirical findings suggest that inequities in health correlate with inequities in job quality, though a substantial fraction of these associations reflect time-constant unobserved heterogeneity. Still, there is evidence for genuine protective effects of better jobs on musculoskeletal disorders, mental health and general health. The effect could contribute to a substantial number of avoidable disorders among older workers, despite relatively modest effect sizes at the level of individuals. Mental health, in particular, responds to changes in job quality. Selection bias such as the healthy worker effect does not alter the results. But the influence of job quality on health may be transitional among older workers. An in-depth analysis of health dynamics reveals no evidence for persistence.

    Full Text Available In recent decades, because of significant progress in the analysis and detection of trace pollutants, emerging contaminants have been discovered and quantified in living beings and diverse environmental substances; however, the adverse effects of environmental exposure on the general population are largely unknown. This review summarizes the conclusions of the comprehensive epidemic literature and representative case reports relevant to emerging contaminants and the human body to address concerns about potential harmful health effects in the general population. The most prevalent emerging contaminants include perfluorinated compounds, water disinfection byproducts, gasoline additives, manufactured nanomaterials, human and veterinary pharmaceuticals, and UV-filters. Rare but statistically meaningful connections have been reported for a number of contaminants and cancer and reproductive risks. Because of contradictions in the outcomes of some investigations and the limited number of articles, no significant conclusions regarding the relationship between adverse effects on humans and extents of exposure can be drawn at this time. Here, we report that the current evidence is not conclusive and comprehensive and suggest prospective cohort studies in the future to evaluate the associations between human health outcomes and emerging environmental contaminants.

    The use of electronic cigarettes or e-cigarettes is strongly on the rise. The literature confirms that in the process of quitting smoking using an electronic device dispensing nicotine should be a transitional stage before the complete cessation of smoking. The aim of the present study was to assess the popularity of e-cigarettes, the underlying reasons for use of such nicotine products, and the level of awareness of health hazards associated with e-cigarettes. The study is of a survey type. The material consisted of data collected from an anonymous survey distributed among 46 female and 23 male users of e-cigarettes in 2015. We used a questionnaire of our own design. The findings demonstrate that the main reason for a recourse to e-cigarettes is a desire to use fashionable technological innovations, and the conviction that such cigarettes are less harmful than the traditional tobacco products. Some respondents used e-cigarettes to quit smoking; others to minimize the harmful effects of smoking. Most respondents acquired information about e-cigarettes from friends or from the Internet. There was a high awareness of the chemical composition of substances contained in e-cigarettes. An interest in e-cigarettes is caused by an increased knowledge on the negative effects of traditional smoking. Currently, the e-cigarettes remains a technological novelty, so that the exact health effects of their long-term use are open to conjecture.

    This paper reviews the literature describing research performed over the past decade on the known and possible exposures and human health effects associated with Florida red tides. These harmful algal blooms are caused by the dinoflagellate, Karenia brevis, and similar organisms, all of which produce a suite of natural toxins known as brevetoxins. Florida red tide research has benefited from a consistently funded, long term research program, that has allowed an interdisciplinary team of researchers to focus their attention on this specific environmental issue—one that is critically important to Gulf of Mexico and other coastal communities. This long-term interdisciplinary approach has allowed the team to engage the local community, identify measures to protect public health, take emerging technologies into the field, forge advances in natural products chemistry, and develop a valuable pharmaceutical product. The Review includes a brief discussion of the Florida red tide organisms and their toxins, and then focuses on the effects of these toxins on animals and humans, including how these effects predict what we might expect to see in exposed people.

    2014-08-01

    Full Text Available Women seeking to become pregnant and pregnant women are currently advised to consume high amounts of folic acid and other methyl donors to prevent neural tube defects in their offspring. These diets can alter methylation patterns of several biomolecules, including nucleic acids and histone proteins. Limited animal model data suggests that developmental exposure to these maternal methyl supplemented (MS diets leads to beneficial epimutations. However, other rodent and humans studies have yielded opposing findings with such diets leading to promiscuous epimutations that are likely associated with negative health outcomes. Conflict exists to whether these maternal diets are preventative or exacerbate the risk for ASD in children. This review will discuss the findings to date on the potential beneficial and aversive effects of maternal MS diets. We will also consider how other factors might influence the effects of MS diets. Current data suggest that there is cause for concern as maternal MS diets may lead to epimutations that underpin various diseases, including neurobehavioral disorders. Further studies are needed to explore the comprehensive effects maternal MS diets have on the offspring epigenome and subsequent overall health.

    Between March 28 and April 15, 1979 the collective dose resulting from the radioactivity released to the population living within a 50-mile radius of the Three Mile Island nuclear plant was about 2000 person-rems, less than 1% of the annual natural background level. The average dose to a person living within 5 miles of the nuclear plant was less than 10% of annual background radiation. The maximum estimated radiation dose received by any one individual in the general population (excluding the nuclear plant workers) during the accident was 70 mrem. The doses received by the general population as a result of the accident were so small that there will be no detectable additional cases of cancer, developmental abnormalities, or genetic ill-health. Three Three Mile Island nuclear workers received radiation doses of about 3 to 4 rem, exceeding maximum permissible quarterly dose of 3 rem. The major health effect of the accident at Three Mile Island was that of a pronounced demoralizing effect on the general population in the Three Mile Island area, including teenagers and mothers of preschool children and the nuclear plant workers. However, this effect proved transient in all groups studied except the nuclear workers

    The effects of occupational experience with microwave radiation (radar) on the health of US enlisted Naval personnel were studied in cohorts of approximately 20,000 men with maximum opportunity for exposure (electronic equipment repair) and 20,000 with minimum potential for exposure (equipment operation) who served during the Korean War period. Potential exposure was assessed in terms of occupational duties, length of time in occupation and power of equipment at the time of exposure. Actual exposure to members of each cohort could not be established. Mortality by cause of death, hospitalization during military service, later hospitalization in Veterans Administration (VA) facilities, and VA disability compensation were the health indexes studied, largely through the use of automated record systems. No adverse effects were detected in these indexes that could be attributed to potential microwave radiation exposures during the period 1950-1954. Functional and behavioral changes and ill-defined conditions, such as have been reported as microwave effects, could not be investigated in this study but subgroups of the living study population can be identified for expanded follow-up

    To determine the effects of the adoption of ambulatory electronic health information exchange (HIE) on rates of laboratory and radiology testing and allowable charges. Claims data from the dominant health plan in Mesa County, Colorado, from 1 April 2005 to 31 December 2010 were matched to HIE adoption data on the provider level. Using mixed effects regression models with the quarter as the unit of analysis, the effect of HIE adoption on testing rates and associated charges was assessed. Claims submitted by 306 providers in 69 practices for 34 818 patients were analyzed. The rate of testing per provider was expressed as tests per 1000 patients per quarter. For primary care providers, the rate of laboratory testing increased over the time span (baseline 1041 tests/1000 patients/quarter, increasing by 13.9 each quarter) and shifted downward with HIE adoption (downward shift of 83, prates or imputed charges in either provider group. Ambulatory HIE adoption is unlikely to produce significant direct savings through reductions in rates of testing. The economic benefits of HIE may reside instead in other downstream outcomes of better informed, higher quality care.

    The impact of health information technology (HIT) in hospitals is dependent in large part on how it is used by nurses. This study examines the impact of HIT on the quality of care in hospitals in the Veterans Health Administration (VA), focusing on nurse-sensitive outcomes from 1995 to 2005. Data were obtained from VA databases and original data collection. Fixed-effects Poisson regression was used, with the dependent variables measured using the Agency for Healthcare Research and Quality Inpatient Quality Indicators and Patient Safety Indicators software. Dummy variables indicated when each facility began and completed implementation of each type of HIT. Other explanatory variables included hospital volume, patient characteristics, nurse characteristics, and a quadratic time trend. The start of computerized patient record implementation was associated with significantly lower mortality for two diagnoses but significantly higher pressure ulcer rates, and full implementation was associated with significantly more hospital-acquired infections. The start of bar-code medication administration implementation was linked to significantly lower mortality for one diagnosis, but full implementation was not linked to any change in patient outcomes. The commencement of HIT implementation had mixed effects on patient outcomes, and the completion of implementation had little or no effect on outcomes. This longitudinal study provides little support for the perception of VA staff and leaders that HIT has improved mortality rates or nurse-sensitive patient outcomes. Future research should examine patient outcomes associated with specific care processes affected by HIT. Copyright © 2014 Elsevier Inc. All rights reserved.

  19. Potential exposures and health effects from spent fuel transportation

    Sandquist, G.M.; Rogers, V.C.

    1986-01-01

    The radiation exposures and consequent health effects associated with normal operations and accidents during transportation of spent fuel have been analyzed and evaluated. This study was performed for the U.S. Department of Energy (DOE) as contributory data for response to specific public inquires regarding the Draft Environmental Assessments issued by DOE in 1984. Large quantities of spent fuel from power reactors will be shipped by truck and/or rail from the site of generation or temporary storage to nuclear waste repositories. This transportation activity has the potential for increasing radiation exposures and risks above normal background levels in the vicinity of the transportation route. For normal, accident-free transport of spent fuel, radiation exposures arise from both gamma and neutron sources within the spent fuel cask. U.S. regulations limit the radiation dose equivalent rate to 10 millirem per hour at any point 2 meters from the outer lateral surfaces of the transport vehicle. Computer program PATHRAE-T was developed and employed to determine the total, combined dose field. PATHRAE-T was used to estimate the maximum individual doses from rail cask accidents. The maximum individual exposure, primarily due to inhalation, is about 10 rem and occurs about 70 meters downwind. Ground deposited nuclides account for 99 percent of the population dose. The maximum population dose accident could result in about 22 latent health effects for the urban population. The same case rail cask accidents were also evaluated for a maximum water pathway contamination scenario. The nuclide contaminated plume was assumed to be transported over a large reservoir used for domestic and agricultural water. This accident could result in a 63,000 person-rem dose causing about 13 latent health effects in the absence of any natural and industrial processes for nuclide removal from the water
