  1. Lorcaserin. In obesity: unacceptable risks.

    PubMed

    2014-05-01

    Treatment of obesity and overweight is based primarily on dietary measures and physical exercise.There are still no drugs with a favourable harm-benefit balance in this setting. Lorcaserin, a "selective" 5HT2C serotonin receptor agonist, has been refused marketing authorisation in the European Union despite approval in the United States. Clinical evaluation of lorcaserin is based on three placebo-controlled trials, each lasting one year, in a total of about 6000 patients. Two trials involved obese patients, and one obese patients with type 2 diabetes. The results of these trials are undermined by the large proportion (40% to 50%) of patients who were lost to follow-up before the end of the trial. None of the trials examined the impact of lorcaserin on the clinical complications of obesity. From an average initial weight of about 100 kg, patients taking lorcaserin lost only about 3 kg more than those in the placebo groups.The patients put on weight again after lorcaserin was discontinued. Adverse effects observed in clinical trials were mainly gastrointestinal (dry mouth, nausea) and neuropsychiatric (dizziness, fatigue, headache, euphoria). The incidence of cardiac valve disorders was higher with lorcaserin than with placebo. These trials were too short in duration to exclude a risk of cancer (breast cancer and astrocytoma) that was reported in experimental animals. This serotonin agonist is metabolised by the liver, creating a risk of multiple drug interactions. In practice, lorcaserin has not been shown to prevent complications of obesity or even lead to substantial weight loss.There is therefore no justification for exposing patients to the risk of adverse effects.

  2. Ethical Perspective: Five Unacceptable Trade-offs on the Path to Universal Health Coverage.

    This article discusses what ethicists have called "unacceptable trade-offs" in health policy choices related to universal health coverage (UHC). Since the fiscal space is constrained, trade-offs need to be made. But some trade-offs are unacceptable on the path to universal coverage. Unacceptable choices include, among other examples from low-income countries, to expand coverage for services with lower priority such as coronary bypass surgery before securing universal coverage for high-priority services such as skilled birth attendance and services for easily preventable or treatable fatal childhood diseases. Services of the latter kind include oral rehydration therapy for children with diarrhea and antibiotics for children with pneumonia. The article explains why such trade-offs are unfair and unacceptable even if political considerations may push in the opposite direction. PMID:26673330

    The 40th annual report of the UN Children's Emergency Fund (UNICEF) states that about 7 million of the 14 million children who die throughout the world each year could be saved by modern methods of health care and food supply. UNICEF's executive director James Grant points out that 40 years ago little international attention was given to mass death from starvation, but today any such crisis attracts the mass media, and people and governments act to avoid mass death. Undernourishment and epidemics continue to threaten the world's children and more than 280,000 children die from these causes each week. Even with the crises of the past two years in Africa there have been more deaths among children in India and Pakistan than in all of Africa's 46 countries together. Existing knowledge on cheap methods of improving the health of children in underdeveloped countries is sufficient to save at least 7 million children's lives each year. Many millions more could have a normal growth with better information on replacements on mother's milk, vaccinations and access to supplies of water, sugar, and salt for oral rehydration therapy. Just as important are the new technologies of the communications revolution which is taking place in underdeveloped countries. Most homes have a radio, and televisions are available in most villages and in many small communities there are schools and health workers. PMID:3424127

  4. Ethnocentrism is an unacceptable rationale for health care policy: a critique of transplant tourism position statements.

    2008-06-01

    Medical tourism has emerged as a global health care phenomenon, valued at $60 billion worldwide in 2006. Transplant tourism, unlike other more benign forms of medical tourism, has become a flashpoint within the transplant community, underscoring the uneasy relationships among science, religion, politics, ethics and international health care policies concerning the commercialization of transplantation. Numerous professional associations have drafted or issued position statements condemning transplant tourism. Often the criticism is misdirected. The real issue concerns both the source and circumstances surrounding the procurement of donor organs, including commercialization. Unfortunately, many of the position statements circulated to date represent an ethnocentric and decidedly western view of transplantation. As such, the merits of culturally insensitive policy statements issued by otherwise well-intended transplant professionals, and the organizations they represent, must be evaluated within the broader context of foreign relations and diplomacy, as well as cultural and ethical relativity. Having done so, many persons may find themselves reluctant to endorse statements that have produced a misleading social desirability bias, which, to a great extent, has impeded more thoughtful and inclusive deliberations on the issues. Therefore, instead of taking an official position on policy matters concerning the commercial aspects of transplantation, international professional associations should offer culturally respectful guidance.

    The health risks associated with ozone depletion will principally be those due to increased ultraviolet B (UV-B) radiation in the environment, i.e., increased damage to the eyes, the immune system, and the skin. Some new risks may also be introduced with the increased use of alternatives to the ozone-depleting substances (ODSs). Quantitative risk estimates are available for some of the UV-B-associated effects, e.g., cataract and skin cancer; however, the data are insufficient to develop similar estimates for effects such as immunosuppression and the toxicity of alternatives. Ocular damage from UV exposures includes effects on the cornea, lens, iris, and associated epithelial and conjunctival tissues. The most common acute ocular effect of environmental ultraviolet radiation (UVR) is photokeratitis. Also known as snowblindness in skiers, this condition also occurs in other outdoor recreationists. Chronic eye conditions likely to increase with ozone depletion include cataract, squamous cell carcinoma, ocular melanoma, and a variety of corneal/conjunctival effects, e.g., pterygium and pinguecula. Suppression of local (at the site of UV exposure) and systemic (at a distant, unexposed site) immune responses to a variety of antigens has been demonstrated in both humans and animals exposed to UV-B. In experiments with animals these effects have been shown to worsen the course/outcome of some infectious diseases and cancers. There is reasonably good evidence that such immunosuppression plays a role in human carcinogenesis; however, the implications of such immunosuppression for human infectious diseases are still unknown. In light-skinned populations, exposure to solar UVR appears to be the most important environmental risk factor for basal and squamous cell carcinomas and cutaneous melanoma. Originally it was believed that total accumulated exposure to UVR was the most important environmental factor in determining risk for these tumors. Recent information now suggests

    Lanestosa is a chronically polluted site (derelict mine) where the soil (Lanestosa (LA) soil) exceeds screening values (SVs) of regulatory policies in force (Basque Country; Europe) for Zn, Pb and Cd. A scenario-targeted toxicity assessment was carried out on the basis of a multi-endpoint bioassay approach. Acute and chronic toxicity bioassays were conducted with selected test species (Vibrio fischeri, Dictyostelium discoideum, Lactuca sativa, Raphanus sativus and Eisenia fetida) in combination with chemical analysis of soils and elutriates and with bioaccumulation studies in earthworms. Besides, the toxicity profile was compared with that of the mine runoff (RO) soil and of a fresh artificially polluted soil (LAAPS) resembling LA soil pollutant profile. Extractability studies in LA soil revealed that Pb, Zn and Cd were highly available for exchange and/or release into the environment. Indeed, Pb and Zn were accumulated in earthworms and LA soil resulted to be toxic. Soil respiration, V. fischeri, vegetative and developmental cycles of D. discoideum and survival and juvenile production of E. fetida were severely affected. These results confirmed that LA soil had unacceptable environmental risk and demanded intervention. In contrast, although Pb and Zn concentrations in RO soil revealed also unacceptable risk, both metal extractability and toxicity were much lower than in LA soil. Thus, within the polluted site, the need for intervention varied between areas that posed dissimilar risk. Besides, since LAAPS, with a high exchangeable metal fraction, was the most toxic, ageing under in situ natural conditions seemingly contributed to attenuate LA soil risk. As a whole, combining multi-endpoint bioassays with scenario-targeted analysis (including leaching and ageing) provides reliable risk assessment in soils posing unacceptable environmental risk according to SVs, which is useful to optimise the required intervention measures.

    Adair, J. Kathleen

    This study explored science-specific strategies and materials that might be effective components in a Response to Intervention (RTI) science tutorial model for at-risk, academically unsuccessful students in grades 4 -- 8. Through an iterative Delphi process of responding to three rounds of questionnaires, a nationwide panel of 63 experts in the field of science education identified and came to consensus on 44 effective strategies and six instructional materials and types of equipment for supplemental instruction in science, resulting in a three tier RTI tutorial model. This model provides an initial guide for science educators in applicable practices for each tier of the RTI framework, and was developed to assist administrators, program managers, and science educators in developing effective, systemic RTI instructional programming for science education in grades 4 -- 8, and may provide an additional planning tool in determining evidence-based practices that may lead to achievement for at-risk, academically unsuccessful students in grades 4 -- 8. Future research on specific intervention strategies within science and their effects on science achievement are needed, as well as a further examination to test the efficacy of the model on rates of science achievement for at-risk, academically unsuccessful students.

    Pesticides are a category of chemicals formulated to kill or repel a pest or halt its reproduction. In this article we review the toxicological and epidemiological literature; describe common potential pesticide exposures; and focus on the associated health risks to fetal development. Clinical implications are reviewed, and recommendations are made regarding the integration of this environmental health concern into nursing education, practice, research, and policy/advocacy work. Recommendations for pesticide elimination and reduction in health care settings are included. PMID:20409108

    Passive sampling devices (PSDs) sequester the freely dissolved fraction of lipophilic contaminants, mimicking passive chemical uptake and accumulation by biomembranes and lipid tissues. Public Health Assessments that inform the public about health risks from exposure to contaminants through consumption of resident fish are generally based on tissue data, which can be difficulties to obtain and requires destructive sampling. The purpose of this study is to apply PSD data in a Public Health Assessment to demonstrate that PSDs can be used as a biological surrogate to evaluate potential human health risks and elucidate spatio-temporal variations in risk. PSDs were used to measure polycyclic aromatic hydrocarbons (PAHs) in the Willamette River; upriver, downriver and within the Portland Harbor Superfund megasite for three years during wet and dry seasons. Based on an existing Public Health Assessment for this area, concentrations of PAHs in PSDs were substituted for fish tissue concentrations. PSD measured PAH concentrations captured the magnitude, range and variability of PAH concentrations reported for fish/shellfish from Portland Harbor. Using PSD results in place of fish data revealed an unacceptable risk level for cancer in all seasons but no unacceptable risk for non-cancer endpoints. Estimated cancer risk varied by several orders of magnitude based on season and location. Sites near coal tar contamination demonstrated the highest risk, particularly during the dry season and remediation activities. Incorporating PSD data into Public Health Assessments provides specific spatial and temporal contaminant exposure information that can assist public health professionals in evaluating human health risks.

    2010-01-01

    By 2010, the worldwide annual production of plastics will surpass 300 million tons. Plastics are indispensable materials in modern society, and many products manufactured from plastics are a boon to public health (e.g., disposable syringes, intravenous bags). However, plastics also pose health risks. Of principal concern are endocrine-disrupting properties, as triggered for example by bisphenol A and di-(2-ethylhexyl) phthalate (DEHP). Opinions on the safety of plastics vary widely, and despite more than five decades of research, scientific consensus on product safety is still elusive. This literature review summarizes information from more than 120 peer-reviewed publications on health effects of plastics and plasticizers in lab animals and humans. It examines problematic exposures of susceptible populations and also briefly summarizes adverse environmental impacts from plastic pollution. Ongoing efforts to steer human society toward resource conservation and sustainable consumption are discussed, including the concept of the 5 Rs--i.e., reduce, reuse, recycle, rethink, restrain--for minimizing pre- and postnatal exposures to potentially harmful components of plastics.

    Maintenance of human health on long-duration exploration missions is a primary challenge to mission designers. Indeed, human health risks are currently the largest risk contributors to the risks of evacuation or loss of the crew on long-duration International Space Station missions. We describe a quantitative assessment of the relative probabilities of occurrence of the individual risks to human safety and efficiency during space flight to augment qualitative assessments used in this field to date. Quantitative probabilistic risk assessments will allow program managers to focus resources on those human health risks most likely to occur with undesirable consequences. Truly quantitative assessments are common, even expected, in the engineering and actuarial spheres, but that capability is just emerging in some arenas of life sciences research, such as identifying and minimize the hazards to astronauts during future space exploration missions. Our expectation is that these results can be used to inform NASA mission design trade studies in the near future with the objective of preventing the higher among the human health risks. We identify and discuss statistical techniques to provide this risk quantification based on relevant sets of astronaut biomedical data from short and long duration space flights as well as relevant analog populations. We outline critical assumptions made in the calculations and discuss the rationale for these. Our efforts to date have focussed on quantifying the probabilities of medical risks that are qualitatively perceived as relatively high risks of radiation sickness, cardiac dysrhythmias, medically significant renal stone formation due to increased calcium mobilization, decompression sickness as a result of EVA (extravehicular activity), and bone fracture due to loss of bone mineral density. We present these quantitative probabilities in order-of-magnitude comparison format so that relative risk can be gauged. We address the effects of

    Almost daily, Americans receive reports from the mass news media about some new and frightening risk to health and welfare. Most such reports emphasize the newsworthiness of the risks -- the possibility of a crisis, disagreements among experts, how things happened, who is responsible for fixing them, how much will it cost, conflict among parties involved, etc. As a rule, the magnitudes of the risks, or the difficulty of estimating those magnitudes, have limited newsworthiness, and so they are not mentioned. Because of this emphasis in the news media, most people outside the risk assessment community must judge the relative significance of the various risks to which we all are exposed with only that information deemed newsworthy by reporters. This information is biased and shows risks in isolation. There is no basis for understanding and comparing the relative importance of risks among themselves, or for comparing one risk, perhaps a new or newly-discovered one, in the field of all risks. The purpose of this report is to provide perspective on the various risks to which we are routinely exposed. It serves as a basis for understanding the meaning of quantitative risk estimates and for comparing new or newly-discovered risks with other, better-understood risks. Specific emphasis is placed on health risks of energy technologies.

    Interior air environment and health problems of vehicles have attracted increasing attention, and benzene homologues (BHs) including benzene, toluene, ethylbenzene, xylenes, and styrene are primary hazardous gases in vehicular cabins. The BHs impact on the health of passengers and drivers in 38 taxis is assessed, and health risk equations of in-car BHs to different drivers and passengers are induced. The health risk of in-car BHs for male drivers is the highest among all different receptors and is 1.04, 6.67, and 6.94 times more than ones for female drivers, male passengers, and female passengers, respectively. In-car BHs could not lead to the non-cancer health risk to all passengers and drivers as for the maximal value of non-cancer indices is 0.41 and is less than the unacceptable value (1.00) of non-cancer health risk from USEPA. However, in-car BHs lead to cancer health risk to drivers as for the average value of cancer indices is 1.21E-04 which is 1.21 times more than the unacceptable value (1.00E-04) of cancer health risk from USEPA. Finally, for in-car airborne benzene concentration (X, μg/m(3)) to male drivers, female drivers, male passengers, and female passengers, the cancer health risk equations are Y = 1.48E-06X, Y = 1.42E-06X, Y = 2.22E-07X, and Y = 2.13E-07X, respectively, and the non-cancer health risk equations are Y = 1.70E-03X, Y = 1.63E-03X, Y = 2.55E-04X, and Y = 2.45E-04X, respectively.

    Health security has become a popular way of justifying efforts to control catastrophic threats to public health. Unfortunately, there has been little analysis of the concept of health security, nor the relationship between health security and other potential aims of public health policy. In this paper I develop an account of health security as an aversion to risky policy options. I explore three reasons for thinking risk avoidance is a distinctly worthwhile aim of public health policy: (i) that security is intrinsically valuable, (ii) that it is necessary for social planning and (iii) that it is an appropriate response to decision-making in contexts of very limited information. Striking the right balance between securing and maximizing population health thus requires a substantive, and hitherto unrecognized, value judgment. Finally, I critically evaluate the current health security agenda in light of this new account of the concept and its relationship to the other aims of public health policy. PMID:26990349

    Risk can lead to catastrophe. Risk-management systems are highly effective in preventing the catastrophes of fire, earthquakes, and work-site injuries. No such effective systems are present to prevent health and social problems. A practical, cost-effective system to manage risk in children is being developed by the nonprofit Arizona Health Evaluation and Longevity Planning (HELP) Foundation. Information regarding such risk is collected in the school setting. This voluntary information comes from the administration, the school nurse, physical fitness testing, blood testing by the local hospital, self-esteem instruments, and parent, teacher, and child questionnaires. The HELP Foundation then develops an individual child and class risk profile that is presented to the teacher, school nurse, principal, and parent. Those involved with each child then prioritize, plan, and implement programs and activities to manage the identified risk(s). Risks is tracked throughout the child's school career by periodic reassessment. Evaluation of change in problem outcome will be a natural extension of the process. PMID:1643740

    Health risks from fossil, renewable and nuclear reference energy systems are estimated following a detailed impact pathway approach. Using a set of appropriate air quality models and exposure-effect functions derived from the recent epidemiological literature, a methodological framework for risk assessment has been established and consistently applied across the different energy systems, including the analysis of consequences from a major nuclear accident. A wide range of health impacts resulting from increased air pollution and ionizing radiation is quantified, and the transferability of results derived from specific power plants to a more general context is discussed.

    Many work activities include hazards to workers, and among these biological risk is particularly important, mostly because of different types of exposure, contact with highly dangerous agents, lack of limit values able to compare all exposures, presence of workers with defective immune systems and therefore more susceptible to the risk. Bioaerosols and dust are considered important vehicles of microganisms at workplaces and interaction with other occupational agents is assumed. Moreover, biological risk can be significant in countries with increasing economic development or particular habits and some biological agents are also classified as carcinogenic to human. Specific emerging biological risks have been recently pointed out by Risk Observatory of the European Agency for Safety and Health at work, and we must consider the worker's attitude and behaviour, influenced by his own perception of risk more than his real knowledge, that could over-underestimate the risk itself. Therefore, biological risk at work requires a complex approach in relation to risk assessment and risk management, made more difficult due to the wide variety of biological agents, working environments and working techniques that can determine the exposures.

    In India, 69% of the children of the working class die, most of whom are child laborers. Economic pressure forces parents to make their children work. Employers want child workers because they can manipulate them and pay them low wages, thereby ensuring their viability. The caste system induces social inequality, inheritance invokes cultural inequality, and patriarchal socialization is responsible for gender inequality, all of which perpetuates exploitation of children by employers. In Sivakasi, an estimated 125,000 children make up the child labor force, comprising 30% of the entire labor force. 75% are from the lowest castes. 90% of child workers are girls because they are more obedient and accept even lower wages than boys, and girls need to save for their dowry. Girls often suffer verbal and physical abuse. Like their parents who were also child workers, child workers are illiterate and work long hours. A small rich elite in Sivakasi controls most of the trading and industrial capital, educational institutions, and voluntary organizations. Employers' agents give parents a loan and use their children's labor as security. Each day, they bring child workers to Sivakasi in factory buses from villages to work at least 12 hour days. They work under hazardous conditions, e.g., working with toxic chemicals. Coughing, sore throat, dizziness, methemoglobinemia, and anemia are common effects of ingestion or inhalation of chlorate dust. Inhalation of sulphur dust causes respiratory infections, eye infections, and chronic lung diseases (e.g., asthma). Fires and explosions are common risks for working children. Factory management seldom undertake fire prevention measures. An extensive survey of the problem of child labor is needed in Sivakasi before systematic planning to protect children could be done. Overall development, especially agricultural development, is needed. Parents, employers, enforcement authorities, trade unions, and social groups need to be sensitized to the

    Gold mining has increased the prevalence and occurrence of heavy metals contamination at the Earth's surface and is causing major concern due to the potential risk involved. This study investigated the impact of gold mine on heavy metals (As, Cd, Cr, Cu, Pb, Hg, Ni, Fe, Mn, and Zn) pollution and evaluated the potential health risks to local residents via consumption of polluted groundwater, agricultural soils, and vegetable crops grown at three community farms surrounding the mine at Obuasi municipality of Ghana. The results showed levels of As, Cd, Cr, Hg, Fe, and Mn higher than the allowable drinking water standards. The vegetable samples analyzed showed high accumulation of As and Ni above the normal value. Bioaccumulation factors of heavy metals were significantly higher for vegetables grown in the Sanso soils. Estimated average daily intake and hazard quotient for As in drinking water as well as As, Pb, and Hg in vegetable samples exceeded permissible limit. Unacceptable non-cancer health risk levels were found in vegetable samples analyzed for As, Pb, and Hg. An unacceptable cancer risk was found via drinking of groundwater, in consumption of vegetables, and in soil. The hazard index for vegetables was higher than 1, indicating very high health risk to heavy metals contamination through consumption of vegetables grown around the sampling sites. The results recommend the need for regular monitoring of groundwater and food crops to protect consumers' health. PMID:27037696

From the initial application in the field of the insurances and the management of the enterprises, theories inspired to the identification, evaluation and correction of connected risks to the activity and the industrial trial has been figurative to the health, field in which the application of these principles results to be how much never profit and productive of benefits above all for the patients that suffer consequences of errors but also for the physicians and the personnel that, perfectly inserted in an organization aware of the trials to put into effect, can bring their contribution to underline the weak points of the relief trial. The economic cost and consequences of errors can decrease if a new culture is established inspired to the learning and the communication of the adverse events, to minimize the possibility that they again occurs.

    A comprehensive analytical review of the risk assessment, risk management, and risk communication approaches currently being undertaken by key national, provincial/state, territorial, and international agencies was conducted. The information acquired for review was used to identify the differences, commonalities, strengths, and weaknesses among the various approaches, and to identify elements that should be included in an effective, current, and comprehensive approach applicable to environmental, human health and occupational health risks. More than 80 agencies, organizations, and advisory councils, encompassing more than 100 risk documents, were examined during the period from February 2000 until November 2002. An overview was made of the most important general frameworks for risk assessment, risk management, and risk communication for human health and ecological risk, and for occupational health risk. In addition, frameworks for specific applications were reviewed and summarized, including those for (1)contaminated sites; (2) northern contaminants; (3) priority substances; (4) standards development; (5) food safety; (6) medical devices; (7) prescription drug use; (8) emergency response; (9) transportation; (10) risk communication. Twelve frameworks were selected for more extensive review on the basis of representation of the areas of human health, ecological, and occupational health risk; relevance to Canadian risk management needs; representation of comprehensive and well-defined approaches; generalizability with their risk areas; representation of "state of the art" in Canada, the United States, and/or internationally; and extent of usage of potential usage within Canada. These 12 frameworks were: 1. Framework for Environmental Health Risk Management (US Presidential/Congressional Commission on Risk Assessment and Risk Management, 1997). 2.

    Chronic shortage of donor organs has heightened interest in new strategies for increasing donor availability. Unacceptable hearts for transplant have previously been characterized by donor age greater than 40 years, more than 20% donor/recipient weight mismatch, ischemic time more than 4 hours, and the presence of coronary artery disease. A series of 185 consecutive orthotopic heart transplants were retrospectively examined. A significant number of donor hearts used were unacceptable by one or more of the above criteria. Our current approach is to match donors to recipients using a wide range of criteria. Donors are now accepted from any location in North America. We have accepted donors more than 55 years of age and donors weighing less than 50% of the recipient's body weight. Because of the chronic shortage of donor organs, donor criteria have been effectively liberalized, thereby increasing the donor pool without compromising the overall results of heart transplantation.

    Although Asian Americans are the fastest growing ethnic minority group in the United States, relatively little is known about the health risks and morbidity of different Asian-American groups. A national survey (National Health Interview Survey) is needed to clarify the health risks of major Asian-American subgroups. (SLD)

    This review provides a basis for substantiating both kinetically and pathologically the differences between chrysotile and amphibole asbestos. Chrysotile, which is rapidly attacked by the acid environment of the macrophage, falls apart in the lung into short fibers and particles, while the amphibole asbestos persist creating a response to the fibrous structure of this mineral. Inhalation toxicity studies of chrysotile at non-lung overload conditions demonstrate that the long (>20 µm) fibers are rapidly cleared from the lung, are not translocated to the pleural cavity and do not initiate fibrogenic response. In contrast, long amphibole asbestos fibers persist, are quickly (within 7 d) translocated to the pleural cavity and result in interstitial fibrosis and pleural inflammation. Quantitative reviews of epidemiological studies of mineral fibers have determined the potency of chrysotile and amphibole asbestos for causing lung cancer and mesothelioma in relation to fiber type and have also differentiated between these two minerals. These studies have been reviewed in light of the frequent use of amphibole asbestos. As with other respirable particulates, there is evidence that heavy and prolonged exposure to chrysotile can produce lung cancer. The importance of the present and other similar reviews is that the studies they report show that low exposures to chrysotile do not present a detectable risk to health. Since total dose over time decides the likelihood of disease occurrence and progression, they also suggest that the risk of an adverse outcome may be low with even high exposures experienced over a short duration.

    Coffey, Patrick S.

    2014-01-01

    Objective: To describe contemporary air dispersion modeling and health risk assessment methodologies applied to alumina refineries and to summarize recent results. Methods: Air dispersion models using emission source and meteorological data have been used to assess ground-level concentrations (GLCs) of refinery emissions. Short-term (1-hour and 24-hour average) GLCs and annual average GLCs have been used to assess acute health, chronic health, and incremental carcinogenic risks. Results: The acute hazard index can exceed 1 close to refineries, but it is typically less than 1 at neighboring residential locations. The chronic hazard index is typically substantially less than 1. The incremental carcinogenic risk is typically less than 10−6. Conclusions: The risks of acute health effects are adequately controlled, and the risks of chronic health effects and incremental carcinogenic risks are negligible around referenced alumina refineries.

    Child health is fundamental to well-being and achievement throughout the life course. Prior research has demonstrated strong associations between familial socioeconomic resources and children’s health outcomes, with especially poor health outcomes among disadvantaged youth who experience a concentration of risks, yet little is known about the influence of maternal health as a dimension of risk for children. This research used nationally representative U.S. data from the National Health Interview Surveys in 2007 and 2008 (N = 7,361) to evaluate the joint implications of maternal health and socioeconomic disadvantage for youth. Analyses revealed that maternal health problems were present in a substantial minority of families, clustered meaningfully with other risk factors, and had serious implications for children’s health. These findings support the development of health policies and interventions aimed at families. PMID:23794751

    Objective Risk communication and management are essential to the ethical conduct of research, yet addressing risks may be time consuming for investigators and institutional review boards (IRBs) may reject study designs that appear too risky. This can discourage needed research, particularly in higher risk protocols or those enrolling potentially vulnerable individuals, such as those with some level of suicidality. Improved mechanisms for addressing research risks may facilitate much needed psychiatric research. This article provides mental health researchers with practical approaches to: 1) identify and define various intrinsic research risks; 2) communicate these risks to others (e.g., potential participants, regulatory bodies, society); 3) manage these risks during the course of a study; and 4) justify the risks. Methods As part of a National Institute of Mental Health (NIMH)-funded scientific meeting series, a public conference and a closed-session expert panel meeting were held on managing and disclosing risks in mental health clinical trials. The expert panel reviewed the literature with a focus on empirical studies and developed recommendations for best practices and further research on managing and disclosing risks in mental health clinical trials. IRB review was not required because there were no human subjects. The NIMH played no role in developing or reviewing the manuscript. Results Challenges, current data, practical strategies, and topics for future research are addressed for each of four key areas pertaining to management and disclosure of risks in clinical trials: identifying and defining risks, communicating risks, managing risks during studies, and justifying research risks. Conclusions Empirical data on risk communication, managing risks, and the benefits of research can support the ethical conduct of mental health research and may help investigators better conceptualize and confront risks and to gain IRB approval.

    2014-01-01

    In the article there is presented the experience of justification of hygienic standards of food safety with the use of criteria for the risk for population health. Health risk assessment under the impact of tetracyclines with food showed that the content of residual amounts of these antibiotics at the level of 10 mg/kg (permissible residual tetracycline accepted in Customs Union Member Countries (CUMC) will not increase the risk to public health, including the most sensitive groups of the population. The assessment ofthe health risk associated with the receipt of ractopamine with food, showed that eating foods containing ractopamine at ADI level (0-1 mg/kg body weight), and even at the limit of quantification levels in meat products, is inadmissible because of unacceptable risk of functional disorders and diseases of the cardiovascular system. The results of the substantiation of the permissible levels of nitrates content in crop production showed that at the level of exposure according to hygienic standards established in the CUMC as at the recommended and actual consumption levels of products ofplant origin, the health risk as carcinogenic and non-carcinogenic, does not exceed acceptable levels. The results of the assessment of the risk associated with the permissible levels of L. monocytogenes in certain food groups showed that an exposure level of hygienic standards established in the CUMC, standards of Codex Alimentarius Commission and EU documents (before release to the market by the manufacturer) the health risk does not exceed the maximum permissible level of the appearance of serious diseases. Adoption of standards of Codex Alimentarius Commission and the EU (for handling products in the market) is not acceptable because it can lead to an unacceptable risk of listeriosis for the population of the Russian Federation as a whole, and for the most sensitive groups.

    Forest health ecological risk assessment is an important factor in forest resources management. In this paper, we selected forest fire, forest disease-pest disasters and acid rain as main risk sources, described the risk resources by probability, intensity and distributing, and mapped each risk source. The endpoints were the damages that the risk acceptor might and these damages might cause ecosystems' organization and function changing under the uncertainty risk sources. Endpoints of forest might compose of productivity descent, reducing biodiversity, forest degrading, forest ecological function declining, furthermore, forest disappearing. We described exposure in terms of intensity, space, and time. In the exposure and hazard analysis, we used fragile index to show frangibility or resistibility (resistibility is reverse to frangibility), and analyzed the damages by different risk sources. Risk assessment and management was the integrated phase of the research. Because of the spatial heterogeneity of risk sources, all risk index were overlaid in the China map by GIS, which divided the region into 30 ecological risk sub-zones (provinces), according to risk index of each risk sub-zone, and the forest in China was divided into six levels of risk zones. In every level of risk zones, we also put forward the countermeasures for forest health ecological risk management. The result of assessment could provide scientific basis for forest management.

    2010-01-01

    Objective To investigate whether parentally bereaved offspring are more likely to engage in health risk behaviors than nonbereaved control offspring. Design Controlled population-based study. Setting Bereaved families were recruited from coroner records and by advertisement. Control families were recruited using random-digit dialing and by advertisement. Participants At 9.0 months after the death, 186 offspring aged 7 to 25 years of parents who died of suicide, accident, or sudden natural death were compared with 167 nonbereaved control offspring. Main Outcome Measures The association of bereavement with health risk behaviors was examined. The prevalences of health risk behaviors on the Youth Risk Behavior Questionnaire were compared between bereaved and nonbereaved offspring. Risk behaviors surveyed were related to unintentional injury, violence, sexual behavior, cigarette smoking, and alcohol or other drug use. Results No statistically significant difference was noted in the examined health risk behaviors between bereaved and nonbereaved offspring. Conclusions Bereaved offspring did not engage in more health risk behaviors compared with nonbereaved offspring. Primary care physicians counseling youth should inquire about health risk behaviors in general. PMID:20603461

    Environmental and occupational health effects associated with exposures to various chemicals are a subject of increasing concern. One recently developed methodology for assessing the health impacts of various chemical compounds involves the classification of similar chemicals into risk-assessment categories (RACs). This report reviews documented human health effects for a broad range of pollutants, classified by RACs. It complements other studies that have estimated human health effects by RAC based on analysis and extrapolation of data from animal research.

  2. Health risk and access to employer-provided health insurance.

    PubMed

    Buchmueller, T C

    1995-01-01

    The attractiveness of a job offering health benefits increases with a worker's expected medical expenditures. At the same time, employers have an incentive to screen out high-risk workers. Evidence from the 1984 Survey of Income and Program Participation indicates that employer screening dominates high-risk workers' desire to select jobs that offer insurance. Workers who describe their health as fair or poor, report difficulty with physical tasks, or have a work-related disability are less likely to receive employer-provided health insurance than healthy workers. Part of this effect is explained by the negative impact of poor health on earnings and labor supply. PMID:7713620

  5. Adjusting Population Risk for Functional Health Status.

    PubMed

    Fuller, Richard L; Hughes, John S; Goldfield, Norbert I

    2016-04-01

    Risk adjustment accounts for differences in population mix by reducing the likelihood of enrollee selection by managed care plans and providing a correction to otherwise biased reporting of provider or plan performance. Functional health status is not routinely included within risk-adjustment methods, but is believed by many to be a significant enhancement to risk adjustment for complex enrollees and patients. In this analysis a standardized measure of functional health was created using 3 different source functional assessment instruments submitted to the Medicare program on condition of payment. The authors use a 5% development sample of Medicare claims from 2006 and 2007, including functional health assessments, and develop a model of functional health classification comprising 9 groups defined by the interaction of self-care, mobility, incontinence, and cognitive impairment. The 9 functional groups were used to augment Clinical Risk Groups, a diagnosis-based patient classification system, and when using a validation set of 100% of Medicare data for 2010 and 2011, this study found the use of the functional health module to improve the fit of observed enrollee cost, measured by the R(2) statistic, by 5% across all Medicare enrollees. The authors observed complex nonlinear interactions across functional health domains when constructing the model and caution that functional health status needs careful handling when used for risk adjustment. The addition of functional health status within existing risk-adjustment models has the potential to improve equitable resource allocation in the financing of care costs for more complex enrollees if handled appropriately.

  5. Health and environmental risks of energy systems

    SciTech Connect

    Hamilton, L.D.

    1984-01-01

    This paper gives four examples of health risk assessments of energy systems: (1) Comparative risk assessment of the health effects of the coal and nuclear fuel cycles. Estimates differ from previous values chiefly by inclusion of ranges of uncertainty, but some coal-cycle numbers were re-estimated. Upper-boundary public disease risks of air pollution from coal-fired plants dominate. Reactors probably account for most of the potential effect of major nuclear accidents. Accidental death rates in electricity generation are low for reactors and higher for coal. (2) Upper boundary air pollution health risks of existing fossil-based energy technologies in the United States. Preliminary mortality estimates were obtained combining potential impacts of three index pollutants - SO/sub 4/, NO/sub 2/, and CO - as independent measures of risk. Four fuel cycle trajectories leading to three end-uses were analyzed. Example results: domestic wood burning has substantial potential impact, with an upper boundary exceeding that of coal; upper-boundary air pollution impacts of gas can exceed those of oil, because of NO/sub 2/. (3) Health risks of acid deposition and other transported air pollutants, carried out as part of an assessment of the US Congress Office of Technology Assessment (OTA) Acid Rain and Transported Air Pollutants - Implications for Public Policy. Three scenarios were examined, leading to estimates of 40,000 to 50,000 annual premature deaths, depending on year (1978 vs 2000) and scenario (holding total emissions constant vs 30% reduction). (4) health effects of uranium mill tailings piles. Mortality risk is estimated to be minuscule (8.7 x 10/sup -9/ average individual lifetime cancer risk from a model mill, compared with 9.5 x 10/sup -4/ for background radiation). Methods that sum risks over the indefinite future are shown to be to be unrealistic. 39 references, 7 figures, 15 tables.

  6. Real Time Radiation Exposure And Health Risks

    2015-01-01

    Radiation from solar particle events (SPEs) poses a serious threat to future manned missions outside of low Earth orbit (LEO). Accurate characterization of the radiation environment in the inner heliosphere and timely monitoring the health risks to crew are essential steps to ensure the safety of future Mars missions. In this project we plan to develop an approach that can use the particle data from multiple satellites and perform near real-time simulations of radiation exposure and health risks for various exposure scenarios. Time-course profiles of dose rates will be calculated with HZETRN and PDOSE from the energy spectrum and compositions of the particles archived from satellites, and will be validated from recent radiation exposure measurements in space. Real-time estimation of radiation risks will be investigated using ARRBOD. This cross discipline integrated approach can improve risk mitigation by providing critical information for risk assessment and medical guidance to crew during SPEs.

    Migration both voluntary and forced is increasing all over the world. People are moving in larger numbers faster and further than at any other time in history. This is happening at a time when many countries are ill-prepared to deal with a changing demography and when policies and attitudes to population movement and immigration are hardening. The health implications of this are many, and, in some cases, illness and death rates associated with migration are exacerbated by a lack of policies needed to make migration a healthy and socially productive process. From a public health point of view, this is having and will continue to have serious ramifications for the people that move, the family they leave behind, and the communities that host the newcomers.

    2014-01-01

    The radiation environment in space poses significant challenges to human health and is a major concern for long duration manned space missions. Outside the Earth's protective magnetosphere, astronauts are exposed to higher levels of galactic cosmic rays, whose physical characteristics are distinct from terrestrial sources of radiation such as x-rays and gamma-rays. Galactic cosmic rays consist of high energy and high mass nuclei as well as high energy protons; they impart unique biological damage as they traverse through tissue with impacts on human health that are largely unknown. The major health issues of concern are the risks of radiation carcinogenesis, acute and late decrements to the central nervous system, degenerative tissue effects such as cardiovascular disease, as well as possible acute radiation syndromes due to an unshielded exposure to a large solar particle event. The NASA Human Research Program's Space Radiation Program Element is focused on characterization and mitigation of these space radiation health risks along with understanding these risks in context of the other biological stressors found in the space environment. In this overview, we will provide a description of these health risks and the Element's research strategies to understand and mitigate these risks.

    The assessment of health risks of policies is an inevitable, although challenging prerequisite for the inclusion of health considerations in political decision making. The aim of our project was to develop a so far missing methodological guide for the assessment of the complex impact structure of policies. The guide was developed in a consensual way based on experiences gathered during the assessment of specific national policies selected by the partners of an EU project. Methodological considerations were discussed and summarized in workshops and pilot tested on the EU Health Strategy for finalization. The combined tool, which includes a textual guidance and a checklist, follows the top-down approach, that is, it guides the analysis of causal chains from the policy through related health determinants and risk factors to health outcomes. The tool discusses the most important practical issues of assessment by impact level. It emphasises the transparent identification and prioritisation of factors, the consideration of the feasibility of exposure and outcome assessment with special focus on quantification. The developed guide provides useful methodological instructions for the comprehensive assessment of health risks of policies that can be effectively used in the health impact assessment of policy proposals. - Highlights: • Methodological guide for the assessment of health risks of policies is introduced. • The tool is developed based on the experiences from several case studies. • The combined tool consists of a textual guidance and a checklist. • The top-down approach is followed through the levels of the full impact chain. • The guide provides assistance for the health impact assessment of policy proposals.

    This article presents the results of a comparative environmental risk-ranking exercise that was conducted in the United Arab Emirates (UAE) to inform a strategic planning process led by the Environment Agency-Abu Dhabi (EAD). It represents the first national-level application of a deliberative method for comparative risk ranking first published in this journal. The deliberative method involves a five-stage process that includes quantitative risk assessment by experts and deliberations by groups of stakeholders. The project reported in this article considered 14 categories of environmental risks to health identified through discussions with EAD staff: ambient and indoor air pollution; drinking water contamination; coastal water pollution; soil and groundwater contamination; contamination of fruits, vegetables, and seafood; ambient noise; stratospheric ozone depletion; electromagnetic fields from power lines; health impacts from climate change; and exposure to hazardous substances in industrial, construction, and agricultural work environments. Results from workshops involving 73 stakeholders who met in five separate groups to rank these risks individually and collaboratively indicated strong consensus that outdoor and indoor air pollution are the highest priorities in the UAE. Each of the five groups rated these as being among the highest risks. All groups rated soil and groundwater contamination as being among the lowest risks. In surveys administered after the ranking exercises, participants indicated that the results of the process represented their concerns and approved of using the ranking results to inform policy decisions. The results ultimately shaped a strategic plan that is now being implemented. PMID:20723144

  11. Health risks in perspective: Judging health risks of energy technologies. Revision 5/94

    The purpose of this report is to provide perspective on the various risks to which man is routinely exposed. It serves as a basis for understanding the meaning of quantitative risk estimates and for comparing new or newly-discovered risks with other, better-understood risks. Specific emphasis is placed on health risks of energy technologies. This report is not a risk assessment; nor does it contain instructions on how to do a risk assessment. Rather, it provides background information on how most of us think about risks and why it is difficult to do it rationally, it provides a philosophy and data with which to do a better job of judging risks more rationally, and it provides an overview of where risks of energy technologies fit within the spectrum of all risks. Much of the quantitative information provided here is on relative risk of dying of various causes. This is not because risk of dying is seen as the most important kind of risk, but because the statistics on mortality rates by cause are the highest quality data available on health risks in the general population.

    Past space missions beyond the confines of the Earth's protective magnetic field have been of short duration and protection from the effects of solar particle events was of primary concern. The extension of operational infrastructure beyond low-Earth orbit to enable routine access to more interesting regions of space will require protection from the hazards of the accumulated exposures of Galactic Cosmic Rays (GCR). There are significant challenges in providing protection from the long-duration exposure to GCR: the human risks to the exposures are highly uncertain and safety requirements places unreasonable demands in supplying sufficient shielding materials in the design. A vigorous approach to future radiation health-risk mitigation requires a triage of techniques (using biological and technical factors) and reduction of the uncertainty in radiation risk models. The present paper discusses the triage of factors for risk mitigation with associated materials issues and engineering design methods.

  17. The risks of innovation in health care.

    PubMed

    Enzmann, Dieter R

    2015-04-01

    Innovation in health care creates risks that are unevenly distributed. An evolutionary analogy using species to represent business models helps categorize innovation experiments and their risks. This classification reveals two qualitative categories: early and late diversification experiments. Early diversification has prolific innovations with high risk because they encounter a "decimation" stage, during which most experiments disappear. Participants face high risk. The few decimation survivors can be sustaining or disruptive according to Christensen's criteria. Survivors enter late diversification, during which they again expand, but within a design range limited to variations of the previous surviving designs. Late diversifications carry lower risk. The exception is when disruptive survivors "diversify," which amplifies their disruption. Health care and radiology will experience both early and late diversifications, often simultaneously. Although oversimplifying Christensen's concepts, early diversifications are likely to deliver disruptive innovation, whereas late diversifications tend to produce sustaining innovations. Current health care consolidation is a manifestation of late diversification. Early diversifications will appear outside traditional care models and physical health care sites, as well as with new science such as molecular diagnostics. They warrant attention because decimation survivors will present both disruptive and sustaining opportunities to radiology. Radiology must participate in late diversification by incorporating sustaining innovations to its value chain. Given the likelihood of disruptive survivors, radiology should seriously consider disrupting itself rather than waiting for others to do so. Disruption entails significant modifications of its value chain, hence, its business model, for which lessons may become available from the pharmaceutical industry's current simultaneous experience with early and late diversifications.

  18. Risk Analysis for Environmental Health Triage

    SciTech Connect

    Bogen, K T

    2005-11-18

    The Homeland Security Act mandates development of a national, risk-based system to support planning for, response to and recovery from emergency situations involving large-scale toxic exposures. To prepare for and manage consequences effectively, planners and responders need not only to identify zones of potentially elevated individual risk, but also to predict expected casualties. Emergency response support systems now define ''consequences'' by mapping areas in which toxic chemical concentrations do or may exceed Acute Exposure Guideline Levels (AEGLs) or similar guidelines. However, because AEGLs do not estimate expected risks, current unqualified claims that such maps support consequence management are misleading. Intentionally protective, AEGLs incorporate various safety/uncertainty factors depending on scope and quality of chemical-specific toxicity data. Some of these factors are irrelevant, and others need to be modified, whenever resource constraints or exposure-scenario complexities require responders to make critical trade-off (triage) decisions in order to minimize expected casualties. AEGL-exceedance zones cannot consistently be aggregated, compared, or used to calculate expected casualties, and so may seriously misguide emergency response triage decisions. Methods and tools well established and readily available to support environmental health protection are not yet developed for chemically related environmental health triage. Effective triage decisions involving chemical risks require a new assessment approach that focuses on best estimates of likely casualties, rather than on upper plausible bounds of individual risk. If risk-based consequence management is to become a reality, federal agencies tasked with supporting emergency response must actively coordinate to foster new methods that can support effective environmental health triage.

    PURPOSE To describe the frequency and patient-reported readiness to change, desire to discuss, and perceived importance of 13 health risk factors in a diverse range of primary care practices. METHODS Patients (n = 1,707) in 9 primary care practices in the My Own Health Report (MOHR) trial reported general, behavioral, and psychosocial risk factors (body mass index [BMI], health status, diet, physical activity, sleep, drug use, stress, anxiety or worry, and depression). We classified responses as “at risk” or “healthy” for each factor, and patients indicated their readiness to change and/or desire to discuss identified risk factors with providers. Patients also selected 1 of the factors they were ready to change as most important. We then calculated frequencies within and across these factors and examined variation by patient characteristics and across practices. RESULTS On average, patients had 5.8 (SD = 2.12; range, 0–13) unhealthy behaviors and mental health risk factors. About 55% of patients had more than 6 risk factors. On average, patients wanted to change 1.2 and discuss 0.7 risks. The most common risks were inadequate fruit/vegetable consumption (84.5%) and overweight/obesity (79.6%). Patients were most ready to change BMI (33.3%) and depression (30.7%), and most wanted to discuss depression (41.9%) and anxiety or worry (35.2%). Overall, patients rated health status as most important. CONCLUSIONS Implementing routine comprehensive health risk assessments in primary care will likely identify a high number of behavioral and psychosocial health risks. By soliciting patient priorities, providers and patients can better manage counseling and behavior change. PMID:25384812

    In 2011, an artificial hook-shaped peninsula of 128ha beach area was created along the Dutch coast, containing thousands of iron ore lumps, which include arsenic from natural origin. Elemental arsenic and inorganic arsenic induce a range of toxicological effects and has been classified as proven human carcinogens. The combination of easy access to the beach and the presence of arsenic raised concern about possible human health effects by the local authorities. The objective of this study is therefore to investigate human health risks from the presence of arsenic-containing iron ore lumps in a beach setting. The exposure scenarios underlying the human health-based risk limits for contaminated land in The Netherlands, based on soil material ingestion and a residential setting, are not appropriate. Two specific exposure scenarios related to the playing with iron ore lumps on the beach ('sandcastle building') are developed on the basis of expert judgement, relating to children in the age of 2 to 12years, i.e., a worst case exposure scenario and a precautionary scenario. Subsequently, exposure is calculated by the quantification of the following factors: hand loading, soil-mouth transfer effectivity, hand-mouth contact frequency, contact surface, body weight and the relative oral bioavailability factor. By lack of consensus on a universal reference dose for arsenic for use in the stage of risk characterization, three different types of assessments have been evaluated: on the basis of the current Provisional Tolerable Daily Intake (PTWI), on the basis of the Benchmark Dose Lower limit (BMDL), and by a comparison of exposure from the iron ore lumps with background exposure. It is concluded, certainly from the perspective of the conservative exposure assessment, that unacceptable human health risks due to exposure to arsenic from the iron ore lumps are unlikely and there is no need for risk management actions.

    This study investigates the potential health risk from urban gardening. The concentrations of the trace elements arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), nickel (Ni), and zinc (Zn) in five common garden crops from three garden sites in Copenhagen were measured. Concentrations (mg/kg dw) of As were 0.002-0.21, Cd 0.03-0.25, Cr < 0.09-0.38, Cu 1.8-8.7, Ni < 0.23-0.62, Pb 0.05-1.56, and Zn 10-86. Generally, elemental concentrations in the crops do not reflect soil concentrations, nor exceed legal standards for Cd and Pb in food. Hazard quotients (HQs) were calculated from soil ingestion, vegetable consumption, measured trace element concentrations and tolerable intake levels. The HQs for As, Cd, Cr, Cu, Ni, and Zn do not indicate a health risk through urban gardening in Copenhagen. Exposure to Pb contaminated sites may lead to unacceptable risk not caused by vegetable consumption but by unintentional soil ingestion. PMID:25796073

    The following paper presents an assessment of health risks associated with air polluted with respirable asbestos fibers in towns of southwest Poland. The aim of the work was to determine whether or not any prevention measures are necessary in order to reduce the level of exposure to the pollutant. The risk assessment was carried out based on the air analyses and the latest asbestos toxicity data published by the Environmental Protection Agency (US EPA), USA and Office of Environmental Health Hazard Assessment (OEHHA). It was found that in some sites, the concentration of the asbestos fibers exceeded the acceptable levels, which should be a reason of special concern. The highest concentration of asbestos was found in town centers during the rush hours. In three spots, the calculated maximum health risk exceeded 1E-04 which is considered too high according to the adopted standards. So far, it has not yet been possible to find a reasonable method of ensuring the hazard reduction. PMID:26070993

    The potential human health and environmental risks of hypothetical one-million-barrels-per-day oil shale industry have been analyzed to serve as an aid in the formulation and management of a program of environmental research. The largest uncertainties for expected fatalities are in the public sector from air pollutants although the occupational sector is estimated to have 60% more expected fatalities than the public sector. Occupational safety and illness have been analyzed for the oil shale fuel cycle from extraction to delivery of products for end use. Pneumoconiosis from the dust environment is the worker disease resulting in the greatest number of fatalities, followed by chronic bronchitis, internal cancer, and skin cancers, respectively. Research recommendations are presented for reducing the uncertainties in the risks analyzed and to fill data gaps to estimate other risks.

    Development efforts since the late 1970s have resulted in a generalized method for ranking health hazards. This method provides the basis for a wide range of applications where decisions are needed for allocating resources on the basis of health risk considerations. It has been used for more than a decade to solve real problems, and it is supported by 23 publications in the open literature. The diversity of this generalized methodology allows us to provide support in a great number of problem areas. we give four examples in this manuscript: the relative toxicities of petroleum mixtures; a method to derive Emergency Response Planning Guides; an estimate of the possible carcinogenic potency of tungsten, an alternative material to depleted uranium for heavy armor penetrators; and an approach to low dose extrapolation. Our experience suggests that many more applications of the original concept and variations on it can be of utility in military situations. Some potentially fruitful areas may be in the: development of a health-risk-ranking system for alternative solutions to manufacturing, waste management, and remediation; provision of a basis for identifying levels of hazardous agents which are below health concerns, or which should be of concern; development of a framework for evaluating chemicals and radioactive materials on the same basis, and in the development of a battery of in vitro bioassays which could take the place of long-term whole animal tests.

    1997-08-01

    We have studied 219353 individual clinical chemistry results obtained in methods comparison studies. Each result was prospectively compared with its replicate, comparative, or repeat value to identify differences from expected values. Unacceptable results were defined as differing from the expected values by < or = 7 SDs or CVs. We believe these differences represent special-cause variation and should be expressed as unacceptable rates per million results (ppm). We observed 447 ppm unacceptables: 196 ppm in control samples and 251 ppm in patients' samples. Results judged likely to alter patient care occurred at a rate of 41 ppm. To better understand the magnitude of these rates, we compared these results with reports of error rates in HIV testing and the airline industry. The measurements reported were made for the purpose of quality improvement, not judgment or discovery. The significance of these findings for laboratorians, manufacturers, and regulators is discussed. PMID:9267313

    Risk assessment and management is a major component of contemporary mental health practice. Risk assessment in health care exists within contemporary perspectives of management and risk aversive practices in health care. This has led to much discussion about the best approach to assessing possible risks posed by people with mental health problems. In addition, researchers and commentators have expressed concern that clinical practice is being dominated by managerial models of risk management at the expense of meeting the patient's health and social care needs. The purpose of the present study is to investigate the risk assessment practices of a multidisciplinary mental health service. Findings indicate that mental health professionals draw on both managerial and therapeutic approaches to risk management, integrating these approaches into their clinical practice. Rather than being dominated by managerial concerns regarding risk, the participants demonstrate professional autonomy and concern for the needs of their clients. PMID:22077745

    This paper surveys recent health care reform debates and empirical evidence regarding the potential role for risk adjusters in addressing the problem of competitive risk segmentation under capitated financing. We discuss features of health plan markets affecting risk selection, methodological considerations in measuring it, and alternative approaches to financial correction for risk differentials. The appropriate approach to assessing risk differences between health plans depends upon the nature of market risk selection allowed under a given reform scenario. Because per capita costs depend on a health plan's population risk, efficiency, and quality of service, risk adjustment will most strongly promote efficiency in environments with commensurately strong incentives for quality care.

    1987-01-01

    Health-promotion efforts often employ HRA as a device for providing an individual with quantitative information about the consequences of personal health-related behaviors and as an attempt to motivate the client to adopt recommendations directed at establishing a healthier lifestyle. From a behavioral science perspective, the HRA approach and process contain elements that (at least in retrospective analysis) appear to be founded in relevant bodies of theory. First, HRA seems to be a reasonably efficient mechanism for transmitting information relative to associations between personal health behaviors and mortality risks. Moreover, while general knowledge and advice about the untoward consequences of risk factors (such as smoking, obesity, high blood pressure, etc.) are currently widespread, HRA provides new and specific information: the client's own relative risks. Some individuals who voluntarily participate in HRA bring to the experience an already high level of readiness to take action; for them, the technique may constitute the final necessary stimulus or "cue to action" [12]. Referring to a "borrowing from the future" phenomenon, Green points out that "some educational efforts are really only triggers to behavior that would have changed eventually anyway" [44, p. 159]. Thus, where motivation is sufficiently high, receipt of HRA feedback information may by itself be capable of inducing behavior change. Second, the focus on awareness and personalization of mortality risk fits well with most theoretical formulations concerning attitudes and beliefs involved in health-related decision making. Although the emphasis on mortality and often distant negative outcomes is problematic, increasing the client's perception of personal vulnerability is a psychologically defensible approach, and fear arousal can generate attitude change (although questions of appropriate level, duration of effects obtained, acceptability, etc. still need to be resolved). Third, HRA might be

    This article reviews central findings and current developments of psychological and sociological research on the perception of health risks. Risk perception is influenced by numerous psychological, social, political, and cultural factors. These factors can be categorized into (a) risk characteristics, (b) characteristics of the risk perceiving person and his/her situation, and (c) characteristics of risk communication. Thus, besides individual cognitive and affective processing of risk information, social processes of risk amplification (e.g., media effects) are also involved in the construction of individual risk perceptions. We discuss the recommendations for health risk communication that follow from these findings with regard to different communication goals. PMID:19862487

    Production agriculture is associated with a variety of occupational illnesses and injuries. Agricultural workers are at higher risk of death or disabling injury than most other workers. Traumatic injury commonly occurs from working with machinery or animals. Respiratory illness and health problems from exposures to farm chemicals are major concerns, and dermatoses, hearing loss, certain cancers, and zoonotic infections are important problems. Innovative means of encouraging safe work practices are being developed. Efforts are being made to reach all groups of farmworkers, including migrant and seasonal workers, farm youth, and older farmers. PMID:9795581

    2015-07-01

    For sediment contaminated with bioaccumulative pollutants (e.g., PCBs and organochorine pesticides), human consumption of seafood that contain bioaccumulated sediment-derived contaminants is a well-established exposure pathway. Historically, regulation and management of this bioaccumulation pathway has focused on site-specific risk assessment. The state of California (United States) is supporting the development of a consistent and quantitative sediment assessment framework to aid in interpreting a narrative objective to protect human health. The conceptual basis of this framework focuses on 2 key questions: 1) do observed pollutant concentrations in seafood from a given site pose unacceptable health risks to human consumers? and 2) is sediment contamination at a site a significant contributor to seafood contamination? The first question is evaluated by interpreting seafood tissue concentrations at the site, based on health risk calculations. The second question is evaluated by interpreting site-specific sediment chemistry data using a food web bioaccumulation model. The assessment framework includes 3 tiers (screening assessment, site assessment, and refined site assessment), which enables the assessment to match variations in data availability, site complexity, and study objectives. The second and third tiers use a stochastic simulation approach, incorporating information on variability and uncertainty of key parameters, such as seafood contaminant concentration and consumption rate by humans. The framework incorporates site-specific values for sensitive parameters and statewide values for difficult to obtain or less sensitive parameters. The proposed approach advances risk assessment policy by incorporating local data into a consistent region-wide problem formulation, applying best available science in a streamlined fashion.

  5. Becoming overweight: is there a health risk?

    PubMed

    Ginter, E; Simko, V

    2014-01-01

    Overweight and obesity is becoming widespread enough to generate an acceptable and misleading social status. By 2030, in the USA up to 86 % of adults will be overweight or obese. Some selected statistical data based on the body mass index (BMI) indicated that overweight was not associated with increased mortality, this provoked a conceivable interest. Added to this is the observation that while the prevalence of obesity is dramatically increasing, the cardiovascular mortality and life expectancy in the European Union and USA has improved. When more sensitive indicators of body adiposity and its distribution than the BMI, like the waist-thigh ratio in both sexes and the waist-hip ratio in women are projected on mortality, it becomes obvious that even overweight is associated with an increased health risk. Gaining excessive body fat is a continuous, frequently progressive process. Present obesity epidemic in childhood will manifest with deleterious consequences only in future years when adolescents reach adulthood. Prevention is thus essential even before the overweight sets in. Improved life expectancy observed in large populations despite obesity epidemic, is a favourable medical success in the management of hypertension, of serum lipid disorders and diabetes. While encouraging, when it is observed in large population, it does not take away the potential health risk of a metabolic disorder in an individual who is overweight (Fig. 7, Ref. 25).

    2005-03-15

    This paper reviews the occurrence and properties of cyanobacterial toxins, with reference to the recognition and management of the human health risks which they may present. Mass populations of toxin-producing cyanobacteria in natural and controlled waterbodies include blooms and scums of planktonic species, and mats and biofilms of benthic species. Toxic cyanobacterial populations have been reported in freshwaters in over 45 countries, and in numerous brackish, coastal, and marine environments. The principal toxigenic genera are listed. Known sources of the families of cyanobacterial toxins (hepato-, neuro-, and cytotoxins, irritants, and gastrointestinal toxins) are briefly discussed. Key procedures in the risk management of cyanobacterial toxins and cells are reviewed, including derivations (where sufficient data are available) of tolerable daily intakes (TDIs) and guideline values (GVs) with reference to the toxins in drinking water, and guideline levels for toxigenic cyanobacteria in bathing waters. Uncertainties and some gaps in knowledge are also discussed, including the importance of exposure media (animal and plant foods), in addition to potable and recreational waters. Finally, we present an outline of steps to develop and implement risk management strategies for cyanobacterial cells and toxins in waterbodies, with recent applications and the integration of Hazard Assessment Critical Control Point (HACCP) principles.

    Cohen, A; Colligan, M J; Berger, P

    1985-08-01

    The content, style, and mode of company communications directed to workers regarding job hazards and health risks are frequently based only on concerns for technical accuracy and legal liability. These considerations as shaping factors in informational messages do not ensure worker understanding and responsiveness. Moreover, the uncertainty of health threats posed by many workplace chemical and physical agents, and the delayed, insidious disorders they may portend, present formidable obstacles in this regard. This report describes guidelines that attempt to overcome these difficulties, with specific reference to printed forms of informational material. The guidelines are based on concepts from the cognitive and social psychology literature, with additional input from experts in those fields as well as representatives from management and labor who have responsibilities for worker health education in their respective organizations. Selected guidelines are presented and critiques are offered of samples of hazard information materials directed to workers in light of the guidelines' prescriptions. Field trials are planned as a follow-up. PMID:4032089

    Evidence indicates that chronic infections and inflammation are associated with increased risk of cancer development. There has also been considerable evidence that proves the interrelationship between bacterial and viral infections and carcinogenesis. Periodontitis is a chronic oral infection thought to be caused by gram-negative anaerobic bacteria in the dental biofilm. Periodontal bacteria and viruses may act synergistically to cause periodontitis. Many studies have shown that periodontal pockets may act as reservoirs for human papilloma virus, cytomegalovirus, Epstein Barr virus, and suspected agents associated with oral cancer. Periodontitis, characterized by epithelial proliferation and migration, results in a chronic release of inflammatory cytokines, chemokines, growth factors, prostaglandins, and enzymes, all of which are associated with cancer development. This review article intends to shed light on the association between periodontal health and carcinogenesis. PMID:24554877

    In this study, the health risk of toxic volatile organic compounds (VOCs) species for well drillers, working at an exposure site around a well of underground coal fire site, was presented in a case of Shanxi province. The samples were collected by Teflon sampling bags and measured by gas chromatography-mass spectrometry (GC-MS). The results showed that isopropyl alcohol was the most abundant compound of VOCs, with the geometric mean concentrations of 1700.38 μg/m(3). The geometric mean concentrations of individual BTEX compounds obtained in all of the sampling campaign were 131.64, 10.15, 15.53, and 25.38 μg/m(3) for benzene, toluene, ethyl-benzene, and xylenes, respectively. Relative proportion of BTEX averaged as 8.5:0.7:1:1.6. High B/T ratio (13.0) and low T/E ratio (0.7) was observed in this study. For non-cancer risk in this study, the hazardous quotient (HQ) of 1,2-dibromoethane, 1,3-butadiene, and benzene was 17.91, 1.71, and 43.88, respectively, mean their non-cancer risk was at the level of definite concern. The HQ sum of 20 VOCs was 64.94, much higher than 1. The cancer risk values of benzene (7.01E-04), 1,2-dibromoethane (1.91E-04), carbon tetrachloride (1.55E-04), and 1,3-butadiene (1.09E-04) were greater than 10(-4), indicating that they were all definite risk. The total cancer risk of all VOCs species was 1.39E-03, almost 14 times more than the level of definite risk. The stochastic exposure assessment of all VOCs species total cancer risk using the Monte Carlo simulation analysis shows that 5 and 95 % cancer risks were predicted to be 7.60E-04 and 2.75E-03, respectively. The cancer risk for all VOCs species is unacceptable. The results of sensitivity analysis show that benzene, carbon tetrachloride, and 1,3-butadiene exposure account for more than 98 % contributions to the estimated risk for drillers, indicating that those VOCs species exposure has greater impact than other species on risk assessment.

    1994-12-01

    This paper reviews a tiered approach to acquiring information from multiple experimental systems to understand and assess the potential human health risks of exposure to airborne synthetic fibers. The approach is grounded in the now widely accepted research-risk assessment-risk management paradigm. It involves the acquisition of information that will provide mechanistic linkages within the exposure-dose-response paradigm. It advocates the use of the inhalation route of exposure for developing relevant information for assessing human health risks and calls attention to serious problems encountered using nonphysiologic routes of administration to assess human health risks.

    The health risk posed by arsenic in vegetables grown in private gardens near 22 contaminated glassworks sites was investigated in this study. Firstly, vegetable (lettuce and potato) and soil samples were collected and arsenic concentrations measured to characterize the arsenic uptake in the selected crops. Secondly, a probabilistic exposure assessment was conducted to estimate the average daily intake (ADIveg), which was then evaluated against toxicological reference values by the calculation of hazard quotients (HQs) and cancer risks (CRs). The results show that elevated arsenic concentrations in residential garden soils are mirrored by elevated concentrations in vegetables, and that consumption of these vegetables alone may result in an unacceptable cancer risk; the calculated reasonable maximum exposure, for example, corresponded to a cancer incidence 20 times higher than the stated tolerance limit. However, the characterization of risk depends to a great extent on which toxicological reference value is used for comparison, as well as how the exposure is determined. Based on the assumptions made in the present study, the threshold levels for chronic non-carcinogenic or acute effects were not exceeded, but the cancer risks indicated highlight the need for further exposure studies, as dietary intake involves more than just homegrown vegetables and total exposure is a function of more than just one exposure pathway. In addition, glassworks sites--and contaminated sites in general--contain multiple contaminants, affecting the final and total risk. PMID:26204055

    Financial, geophysical, and terrorist-related disasters have been headline news in the past few months. As amply demonstrated on a regular basis, the recognition and evaluation of risks are skills that could be more widespread. As such, Proske's Catalogue of Risks is timely and of potential interest. The book is a revised and expanded version of an earlier German publication that aims to provide an encyclopedic discussion of issues related to risks and disasters, with a goal of facilitating an understanding of the components and assessment of risk. The book includes chapters that discuss the difficulty of coming to a consensus on a definition of risk, a comprehensive range of risks and disasters, objective risk measures, subjective risk judgment, quality of life measures, and legal aspects of risk. The book ends with an example of applying the concepts discussed to ship impacts against bridges.

    2005-09-01

    The worldHealth Organization's (WHO's) International Program for Chemical Safety has developed a framework for performing risk assessments that integrate the assessment of risks to human health and risks to nonhuman organisms and ecosystems. The WHO's framework recognizes that stakeholders and risk managers have their own processes that are parallel to the scientific process of risk assessment and may interact with the risk assessment at various points, depending on the context. Integration of health and ecology provides consistent expressions of assessment results, incorporates the interdependence of humans and the environment, uses sentinel organisms, and improves the efficiency and quality of assessments relative to independent human health and ecological risk assessments. The advantage of the framework to toxicologists lies in the opportunity to use understanding of toxicokinetics and toxicodynamics to inform the integrated assessment of all exposed species.

    2003-12-01

    The Environment, Safety and Health Risk Assessment Program (ESHRAP) models human safety and health risk resulting from waste management and environmental restoration activities. Human safety and health risks include those associated with storing, handling, processing, transporting, and disposing of radionuclides and chemicals. Exposures to these materials, resulting from both accidents and normal, incident-free operation, are modeled. In addition, standard industrial risks (falls, explosions, transportation accidents, etc.) are evaluated. Finally, human safety and health impacts from cleanup of accidental releases of radionuclides and chemicals to the environment are estimated. Unlike environmental impact statements and safety analysis reports, ESHRAP risk predictions are meant to be best estimate, rather than bounding or conservatively high. Typically, ESHRAP studies involve risk predictions covering the entire waste management or environmental restoration program, including such activities as initial storage, handling, processing, interim storage, transportation, and final disposal. ESHRAP can be used to support complex environmental decision-making processes and to track risk reduction as activities progress.

    Public concern regarding activities involving radioactive material generally focuses on the human health risk associated with exposure to ionizing radiation. This report describes the results of a risk analysis conducted to evaluate risk for excavation, handling, and transport of soil contaminated with transuranics at the Clean Slate sites. Transportation risks were estimated for public transport routes from the Tonopah Test Range (TTR) to the Envirocore disposal facility or to the Area 3 Radioactive Waste Management Site (RWMS) at the Nevada Test Site (NTS) for both radiological risk and risk due to traffic accidents. Human health risks were evaluated for occupational and radiation-related health effects to workers. This report was generated to respond to this public concern, to provide an evaluation of the risk, and to assess feasibility of transport of the contaminated soil for disposal.

    1986-01-23

    In many cases of radioactive and hazardous waste management, some members of the general public perceive that human health risks associated with the wastes are higher than the calculated risks. Calculated risks are projections that have been derived from models, and it is these risks that are usually used as the basis for waste management. However, for various reasons, the calculated risks are often considered by the public as too low or inappropriate. The reasons that calculated risks are not perceived as accurate and the factors that affect these perceptions are explored in this paper. Also discussed are the impacts related to the perceived and calculated health risks: what they are, and if and how they differ. The kinds of potential impacts examined are health effects, land value changes, and social, transportation, and economic effects. The paper concludes with a discussion of the implications of incorporating these different risk perspectives in decisions on waste management.

    Health Impact Assessment (HIA) is a developing component of the overall impact assessment process and as such needs access to procedures that can enable more consistent approaches to the stepwise process that is now generally accepted in both EIA and HIA. The guidelines developed during this project provide a structured process, based on risk assessment procedures which use consequences and likelihood, as a way of ranking risks to adverse health outcomes from activities subjected to HIA or HIA as part of EIA. The aim is to assess the potential for both acute and chronic health outcomes. The consequences component also identifies a series of consequences for the health care system, depicted as expressions of financial expenditure and the capacity of the health system. These more specific health risk assessment characteristics should provide for a broader consideration of health consequences and a more consistent estimation of the adverse health risks of a proposed development at both the scoping and risk assessment stages of the HIA process. - Highlights: Black-Right-Pointing-Pointer A more objective approach to health risk assessment is provided. Black-Right-Pointing-Pointer An objective set of criteria for the consequences for chronic and acute impacts. Black-Right-Pointing-Pointer An objective set of criteria for the consequences on the health care system. Black-Right-Pointing-Pointer An objective set of criteria for event frequency that could impact on health.

    The ethical debate surrounding the payment of living unrelated donors continues despite very little evidence regarding the outcome. The aim of this audit was to identify the scale of the problem and assess the results of patients undergoing these procedures. The large Indo-Asian population within our region has a high demand for renal replacement therapy and transplantation. These patients have a limited chance of receiving a transplant for several reasons and some resort to traveling abroad, against medical advice, to procure an unrelated donor kidney transplant. Following an initial audit in our region, a national audit was conducted within the UK. A total of 23 patients were identified, all of whom had done so against medical advice. Mortality from causes directly related to transplantation was high in this group (35%), as was graft loss. The overall rate of successful transplants was only 44% (overall graft loss was 56%) in the short term. The information regarding both donor and recipient, provided from the transplanting center, was inadequate in all cases. These results, which almost certainly represent an underestimate of an ongoing situation, reinforce the standpoint that organ trading is associated with unacceptable risks and poor outcomes. The basis of this trade in organs is based on monetary rather than clinical criteria and such exploitation of both donor and recipient lead us to conclude that this practice cannot be endorsed and even the most desperate dialysis patients should be reminded of the unacceptable risks involved in this practice.

    Polycyclic aromatic hydrocarbons (PAHs) produced by coke oven are with strong toxicity and carcinogenicity. Taken typical coke oven of iron and steel enterprises as the case study, the dispersion and migration of 13 kinds of PAHs emitted from coke oven were analyzed using AERMOD dispersion model, the carcinogenic and non-carcinogenic risks at the receptors within the modeling domain were evaluated using BREEZE Risk Analyst and the Human Health Risk Assessment Protocol for Hazardous Waste Combustion (HHRAP) was followed, the health risks caused by PAHs emission from coke oven were quantitatively evaluated. The results indicated that attention should be paid to the non-carcinogenic risk of naphthalene emission (the maximum value was 0.97). The carcinogenic risks of each single pollutant were all below 1.0E-06, while the maximum value of total carcinogenic risk was 2.65E-06, which may have some influence on the health of local residents.

The purpose of this study was to examine health risks and changes in health risks over time in an employed population at a financial services corporation. This large financial services corporation is naturally concerned about any disparities in health among employees. The study population consists of employees who participated in the organization's medical plan and also the annual health risk appraisal questionnaire in both 2009 and 2010. Significant demographic differences exist among the four ethnic groups studied: whites, African Americans, Hispanics, and Asians. At baseline, African American employees had a significantly higher average number of health risks measured by the health risk appraisal, but they also experienced the greatest improvement in health risks by time 2. There were differences in the health risk profiles of the ethnic groups, with certain risk factors being more prevalent among some ethnicities than among others. The health care costs were not significantly different among the groups studied here. It is likely that other large employers may also find health risk differences among employees belonging to various ethnicities. Future research in this field should seek to understand the reasons behind differences in health among ethnic groups and how best to address them so that all employees can achieve a high level of health and wellness.

    2015-05-01

    Results of the recent National Lung Cancer Screening Trial show a significant survival benefit for annual screening with a low-dose computed tomographic (CT) scan in high-risk individuals. This result has led the US Preventive Services Task Force to recommend annual low-dose CT scans for this at-risk population. Less well characterized are the risks from screening. The primary risks from screening are radiation exposure, false-positive results and unnecessary diagnostic and therapeutic procedures, overdiagnosis and overtreatment, and increased psychological distress. This article reviews these risks, which must be considered and weighed against the benefits when discussing enrollment with patients. PMID:25901559

    We developed a risk-based, multi-pollutant air quality health index (AQHI) reporting system in Hong Kong, based on the Canadian approach. We performed time series studies to obtain the relative risks of hospital admissions for respiratory and cardiovascular diseases associated with four air pollutants: sulphur dioxide, nitrogen dioxide, ozone, and particulate matter with an aerodynamic diameter less than 10 μm (PM10). We then calculated the sum of excess risks of the hospital admissions associated with these air pollutants. The cut-off points of the summed excess risk, for the issuance of different health warnings, were based on the concentrations of these pollutants recommended as short-term Air Quality Guidelines by the World Health Organization. The excess risks were adjusted downwards for young children and the elderly. Health risk was grouped into five categories and sub-divided into eleven bands, with equal increments in excess risk from band 1 up to band 10 (the 11th band is 'band 10+'). We developed health warning messages for the general public, including at-risk groups: young children, the elderly, and people with pre-existing cardiac or respiratory diseases. The new system addressed two major shortcomings of the current standard-based system; namely, the time lag between a sudden rise in air pollutant concentrations and the issue of a health warning, and the reliance on one dominant pollutant to calculate the index. Hence, the AQHI represents an improvement over Hong Kong's existing air pollution index.

    Despite being part of a large and legal industry in Los Angeles, little is known about adult film performers’ exposure to health risks and when and how these risks might occur. The objective was to identify exposure to physical, mental, and social health risks and the pathways to such risks among adult film performers and to determine how risks differ between different types of performers, such as men and women. Semi-structured in-depth interviews were conducted with 18 female and ten male performers as well as two key informants from the industry. Performers and key informants were recruited through Protecting Adult Welfare, adult film venues, and snowball sampling. Performers engaged in risky health behaviors that included high-risk sexual acts that are unprotected, substance abuse, and body enhancement. They are exposed to physical trauma on the film set. Many entered and left the industry with financial insecurity and suffered from mental health problems. Women were more likely than men to be exposed to health risks. Adult film performers, especially women, are exposed to health risks that accumulate over time and that are not limited to sexually transmitted diseases. PMID:18709554

    Objective: Primary aluminum production is an industrial process with high potential health risk for workers. We consider in this article how to assess community health risks associated with primary aluminum smelter emissions. Methods: We reviewed the literature on health effects, community exposure data, and dose–response relationships of the principal hazardous agents emitted. Results: On the basis of representative measured community exposure levels, we were able to make rough estimates on health risks associated with specific agents and categorize these as none, low, medium, or high. Conclusions: It is possible to undertake a rough-estimate community Health Risk Assessment for individual smelters on the basis of information available in the epidemiological literature and local community exposure data.

    Risk matrices (RMs) are commonly used to evaluate health and safety risks. Nonetheless, they violate some theoretical principles that compromise their feasibility and use. This study describes how multiple criteria decision analysis methods have been used to improve the design and the deployment of RMs to evaluate health and safety risks at the Occupational Health and Safety Unit (OHSU) of the Regional Health Administration of Lisbon and Tagus Valley. ‘Value risk-matrices’ (VRMs) are built with the MACBETH approach in four modelling steps: a) structuring risk impacts, involving the construction of descriptors of impact that link risk events with health impacts and are informed by scientific evidence; b) generating a value measurement scale of risk impacts, by applying the MACBETH-Choquet procedure; c) building a system for eliciting subjective probabilities that makes use of a numerical probability scale that was constructed with MACBETH qualitative judgments on likelihood; d) and defining a classification colouring scheme for the VRM. A VRM built with OHSU members was implemented in a decision support system which will be used by OHSU members to evaluate health and safety risks and to identify risk mitigation actions.

  7. Ergogenic risks elevate health risks in young athletes.

    PubMed

    Giesemer, Bernard A

    2003-11-01

    Young athletes may use many products and techniques in an attempt to increase competitive edge in sports. The doping techniques that were previously seen in elite adult athletes are now being noted in increasingly competitive elementary, middle, and high school male and female athletes. The risk of significant morbidity and mortality associated with the use of these products is substantially increased when other risk factors are present. The risk for heat-related illness and possible heat-related mortality is higher in physiologically immature, overweight, and poorly conditioned young athletes. These are the same athletes who may be more likely to use stimulant or anabolic steroid products in attempts to catch up on training and conditioning regimens, improve their competitive advantage, or improve their physiques. The risk for heat-related incidents is higher in young athletes who are predisposed to these events because of a family trait or a previous heat-related adverse event in their own medical histories. Combinations of these factors (eg, high osmotic dietary supplements, stimulants, pre-existing medical factors, adverse ambient conditions) may significantly increase a young athlete's chances of a serious, potentially fatal event. Similarly, the risk of cardiac-related sudden death in a young athlete is significantly increased by the use of stimulants such as methamphetamine. As is the case with heat-related adverse events, the risk of cardiac-related morbidity and mortality may be significantly increased when other variables are present, such as the presence of other medications and pre-existing medical factors. As athletic competition becomes increasingly intense for younger athletes, pediatricians need to be aware of the possibility that their young patients are using ergogenic aids that may increase the risk for sudden death significantly. Pediatricians should be aware of the products available to these young competitors, and of the co-factors that

    Objective We sought to examine the legal and ethical implications of workplace health risk reduction programs (HRRPs) using health risk assessments, individually focused risk reduction, and financial incentives to promote compliance. Methods We conducted a literature review, analyzed relevant statutes and regulations, and considered the effects of these programs on employee health privacy. Results A variety of laws regulate HRRPs, and there is little evidence that employer-sponsored HRRPs violate these provisions; infringement on individual health privacy is more difficult to assess. Conclusion Although current laws permit a wide range of employer health promotion activities, HRRPs also may entail largely unquantifiable costs to employee privacy and related interests.

    Legionella is an opportunistic pathogen of public health concern. Current regulatory and management guidelines for the control of this organism are informed by risk assessments. However, there are many unanswered questions and uncertainties regarding Legionella epidemiology, strain infectivity, infectious dose, and detection methods. This review follows the EnHealth Risk Assessment Framework, to examine the current information available regarding Legionella risk and discuss the uncertainties and assumptions. This review can be used as a tool for understanding the uncertainties associated with Legionella risk assessment. It also serves to highlight the areas of Legionella research that require future focus. Improvement of these uncertainties will provide information to enhance risk management practices for Legionella, potentially improving public health protection and reducing the economic costs by streamlining current management practices.

  13. Educated guesses: health risk assessment in environmental impact statements.

    Harvey, P D

    1990-01-01

    Environmental pollution threatens public health. The search for solutions has advanced the frontiers of science and law. Efforts to protect the environment and public health begin with describing potential adverse consequences of human activities and characterizing the predicted risk. The National Environmental Policy Act requires the preparation of environmental impact statements to describe the effects of proposed federal projects and provide information for agency decisionmakers and the public. Risks to public health are particularly difficult to quantify because of uncertainty about the relation between exposure to environmental contamination and disease. Risk assessment is the current scientific tool to present estimates of risk. The methodology has created controversy, however, when underlying assumptions and uncertainties are not clearly presented. Critics caution that the methodology is vulnerable to bias. This Note evaluates the use of risk assessment in the environmental impact statement process and offers recommendations to ensure informed decisions. PMID:2278245

    2013-01-01

    Sexual assault is associated with a number of health risk behaviors in women. It has been hypothesized that these risk behaviors, such as hazardous drinking, may represent women's attempts to cope with psychological distress, such as symptoms of depression and anxiety. However, extant research has failed to evaluate these relationships among ethnic minority samples or identify the mechanisms responsible for this association. The current study examined sexual assault history and two health risk behaviors (hazardous drinking and engaging in sexual behavior to regulate negative affect) in a diverse sample of 1,620 college women. Depression and anxiety were examined as mediators of the relationship between sexual assault and health risk behaviors. There was evidence of moderated mediation, such that for European American women, but not for ethnic minority women, both forms of psychological distress were significant mediators of the sexual assault/hazardous drinking relationship. In contrast, among all ethnic groups, the relationship between sexual assault and both forms of psychological distress was mediated by the use of sexual behavior as an affect regulation strategy. Results support a need to evaluate the assault experiences of ethnically diverse women, as well as the impact of the assault on their postassault experiences including health risk behaviors and psychological adjustment. Additionally, results suggest that practitioners should carefully assess health risk behaviors among victims of sexual assault and be aware that there may be differences in the risk factors and motives for these behaviors among women of various ethnic backgrounds.

    Toxic chemical pollutants such as heavy metals (HMs) are commonly present in urban stormwater. These pollutants can pose a significant risk to human health and hence a significant barrier for urban stormwater reuse. The primary aim of this study was to develop an approach for quantitatively assessing the risk to human health due to the presence of HMs in stormwater. This approach will lead to informed decision making in relation to risk management of urban stormwater reuse, enabling efficient implementation of appropriate treatment strategies. In this study, risks to human health from heavy metals were assessed as hazard index (HI) and quantified as a function of traffic and land use related parameters. Traffic and land use are the primary factors influencing heavy metal loads in the urban environment. The risks posed by heavy metals associated with total solids and fine solids (<150μm) were considered to represent the maximum and minimum risk levels, respectively. The study outcomes confirmed that Cr, Mn and Pb pose the highest risks, although these elements are generally present in low concentrations. The study also found that even though the presence of a single heavy metal does not pose a significant risk, the presence of multiple heavy metals could be detrimental to human health. These findings suggest that stormwater guidelines should consider the combined risk from multiple heavy metals rather than the threshold concentration of an individual species. Furthermore, it was found that risk to human health from heavy metals in stormwater is significantly influenced by traffic volume and the risk associated with stormwater from industrial areas is generally higher than that from commercial and residential areas.

    Following health crisis that have occurred in the nineties (contaminated blood, mad cow, asbestos, etc.) and more recently those generated by the heat wave in 2003 or by emerging infectious pathogens (SARS, West Nile, Chikungunya, H5N1, H1N1…), a real health vigilance system has been progressively developed in France. After a brief historical overview of the health alert system, this article will give the guiding principles of its current organization in France and will present two examples of recent health alerts (Chikungunya in the Reunion Island in 2005-2006 and hepatitis A outbreak in the Côtes-d'Armor in August 2007), that have needed the implementation of preventive measures regarding the blood donor selection. These two examples have shown that the position of the alert in the French health vigilance system needs to be very close to the event. In that case, health alert is a very useful tool for decision making especially when measures have to be taken to prevent transfusion-transmitted pathogens. PMID:21051258

    Objectives To examine associations between weight misperception and youth health risk and protective factors. Methods Three thousand ten US seventh-graders (72.1% white, mean age: 12.7 years) self-reported height, weight, risk, and projective factors. Analyses were conducted to determine cross-sectional and longitudinal associations between weight overestimation and health risk and protective factors. Results Risk and protective factors had significant cross-sectional associations with weight overestimation. However, only depressive symptoms and reduced optimism predicted weight overestimation in eighth grade. Weight overestimation did not predict engagement in risky behaviors. Conclusions Weight overestimation and risk factors appear to co-occur, suggesting a constellation of risk that warrants further research. PMID:22251770

    Environmental exposures during pregnancy have a lasting impact on children's health. We combined environmental and maternal risk factor survey data to inform efforts to protect children's health. We made recommendations for future use of such data. A modified version of the Pregnancy Risk Assessment Monitoring System (PRAMS) mail survey was conducted based on weighted sampling design with low-income and non-low income women in Monroe County, NY (1,022 respondents). A series of environmental questions were included in the questionnaire. Data were analyzed using Chi square tests and Poisson loglinear regression model to identify patterns in environmental health risk and sociodemographic characteristics. We identified women who rented their homes, had lower incomes, and lived in inner city zip codes as "high environmental health risk" (HEHR). HEHR respondents were more likely to report that a health care provider talked with them about lead and on average reported more behaviors to protect their children from lead poisoning. Combining environmental and perinatal risk factor data could yield important recommendations for medical practice, health education, and policy development. However, at present PRAMS gathers only limited and inconsistent environmental data. We found that existing PRAMS environmental questions are insufficient. Further work is needed to develop updated and more comprehensive environmental health survey questions and implement them consistently across the country. PMID:23955384

    2014-01-01

    Introduction Multiple insurance funds serving different population groups may compromise equity due to differential revenue raising capacity and an unequal distribution of high risk members among the funds. This occurs when the funds exist without mechanisms in place to promote income and risk cross-subsidisation across the funds. This paper analyses whether the risk distribution varies across the Community Health Fund (CHF) and National Health Insurance Fund (NHIF) in two districts in Tanzania. Specifically we aim to 1) identify risk factors associated with increased utilisation of health services and 2) compare the distribution of identified risk factors among the CHF, NHIF and non-member households. Methods Data was collected from a survey of 695 households. A multivariate logisitic regression model was used to identify risk factors for increased health care utilisation. Chi-square tests were performed to test whether the distribution of identified risk factors varied across the CHF, NHIF and non-member households. Results There was a higher concentration of identified risk factors among CHF households compared to those of the NHIF. Non-member households have a similar wealth status to CHF households, but a lower concentration of identified risk factors. Conclusion Mechanisms for broader risk spreading and cross-subsidisation across the funds are necessary for the promotion of equity. These include risk equalisation to adjust for differential risk distribution and revenue raising capacity of the funds. Expansion of CHF coverage is equally important, by addressing non-financial barriers to CHF enrolment to encourage wealthy non-members to join, as well as subsidised membership for the poorest.

    2016-06-01

    This study determines the differences in health risk behavior, knowledge, and health benefit beliefs between health science and non-health science university students in 17 low and middle income countries. Anonymous questionnaire data were collected in a cross-sectional survey of 13,042 undergraduate university students (4,981 health science and 8,061 non-health science students) from 17 universities in 17 countries across Asia, Africa, and the Americas. Results indicate that overall, health science students had the same mean number of health risk behaviors as non-health science university students. Regarding addictive risk behavior, fewer health science students used tobacco, were binge drinkers, or gambled once a week or more. Health science students also had a greater awareness of health behavior risks (5.5) than non-health science students (4.6). Linear regression analysis found a strong association with poor or weak health benefit beliefs and the health risk behavior index. There was no association between risk awareness and health risk behavior among health science students and an inverse association among non-health science students. PMID:26538523

    Landfill disposal and waste-to-energy (WTE) incineration remain the two principal options for managing municipal solid waste (MSW). One critical determinant of the acceptability of these options is the different health risks associated with each. In this analysis relying on published data and exposure modeling, we have performed health risk assessments for landfill disposal versus WTE treatment options for the management of New York City’s MSW. These are based on the realistic scenario of using a waste transfer station (WTS) in Brooklyn and then transporting the untreated MSW by truck to a landfill in Pennsylvania or using a WTE facility in Brooklyn and then transporting the resultant ash by truck to a landfill in Pennsylvania. The overall results indicate that the individual cancer risks for both options would be considered generally acceptable, although the risk from landfilling is approximately 5 times greater than from WTE treatment; the individual non-cancer health risks for both options would be considered generally unacceptable, although once again the risk from landfilling is approximately 5 times greater than from WTE treatment. If one considers only the population in Brooklyn that would be directly affected by the siting of either a WTS or a WTE facility in their immediate neighborhood, individual cancer and non-cancer health risks for both options would be considered generally acceptable, but risks for the former remain considerably higher than for the latter. These results should be considered preliminary due to several limitations of this study such as: consideration of risks only from inhalation exposures; assumption that only volume and not composition of the waste stream is altered by WTE treatment; reliance on data from the literature rather than actual measurements of the sites considered, assuming comparability of the sites. However, the results of studies such as this, in conjunction with ecological, socioeconomic and equity considerations

    To reduce the serious health consequences of illegal abortion, the Indonesian Planned Parenthood Association is providing menstrual regulation services. At present, the Association has 15 comprehensive family planning clinics located in 13 out of 27 province capitals. Initially, menstrual regulation was available only in cases of contraceptive failure, but indicators for this service were quickly broadened to meet the large demand for termination of unwanted pregnancies. The ambiguity of the 1992 health law's wording on abortion--abortion is not explicitly mentioned, in an apparent effort to alienate neither anti-abortion forces nor promoters of safe abortion--threatens to stalemate further gains for Indonesian women. Although abortionists are rarely prosecuted, family planning organizations must be cautious to avoid liability suits. The situation in Indonesia is an example of women's health being held hostage to political interests. PMID:12345326

    Objectives Research has demonstrated that packaging which includes pictorial health warnings are more effective in altering smokers’ perceptions and intentions as well as changing smoking behaviours compared to text-only health warnings. However, very few studies have investigated the effectiveness of health warnings on alcoholic beverages Methods Participants (N = 60) viewed alcoholic beverages presenting one of three health warnings (No health warning, Text-only, Pictorial) and then responded to questions relating to level of fear arousal and their perceptions toward alcohol use. Results We found that pictorial health warnings were associated with significantly higher fear arousal, increased perceptions of the health risks of consuming alcohol as well as greater intentions to reduce and quit alcohol consumption compared to the control. Conclusions These novel findings suggest pictorial health warnings on alcoholic beverages may be an important way of making the public aware of the health risks of alcohol consumption. PMID:27105210

    There is a widespread need for the use of quantitative microbial risk assessment (QMRA) to determine reclaimed water quality for specific uses, however neither faecal indicator levels nor pathogen concentrations alone are adequate for assessing exposure health risk. The aim of this study was to build a conceptual model representing factors contributing to the microbiological health risks of reusing water treated in maturation ponds. This paper describes the development of an unparameterised model that provides a visual representation of theoretical constructs and variables of interest. Information was collected from the peer-reviewed literature and through consultation with experts from regulatory authorities and academic disciplines. In this paper we explore how, considering microbial risk as a modular system, following the QMRA framework enables incorporation of the many factors influencing human exposure and dose response, to better characterise likely human health impacts. By using and expanding upon the QMRA framework we deliver new insights into this important field of environmental exposures. We present a conceptual model of health risk of microbial exposure which can be used for maturation ponds and, more importantly, as a generic tool to assess health risk in diverse wastewater reuse scenarios.

    This is a report of a study of Minnesota's high-risk health insurance pool for "medically uninsurable" persons. The study consisted of a survey of current and past enrollees carried out in the Spring of 1990 and an analysis of the claims and membership files for 1988 and 1989. The main policy conclusion we reached is that Minnesota's high-risk pool is an adequate approach to the problem raised by risk segmentation on the basis of health status, providing that enrollment remains a small fraction of the population. The recent high, enrollment growth rates the Minnesota risk pool has experienced raise the possibility that basic structural reforms of the nongroup and small-group health insurance markets are needed.

    South Africa intends implementing major reforms in the financing of healthcare. Free market reforms in private health insurance in the late 1980s have been reversed by the new democratic government since 1994 with the re-introduction of open enrolment, community rating and minimum benefits. A system of national health insurance with income cross-subsidies, risk-adjusted payments and mandatory membership has been envisaged in policy papers since 1994. Subsequent work has seen the design of a Risk Equalisation Fund intended to operate between competing private health insurance funds. The paper outlines the South African health system and describes the risk equalisation formula that has been developed. The risk factors are age, gender, maternity events, numbers with certain chronic diseases and numbers with multiple chronic diseases. The Risk Equalisation Fund has been operating in shadow mode since 2005 with data being collected but no money changing hands. The South African experience of risk equalisation is of wider interest as it demonstrates an attempt to introduce more solidarity into a small but highly competitive private insurance market. The measures taken to combat over-reporting of chronic disease should be useful for countries or funders considering adding chronic disease to their risk equalisation formulae. PMID:20619476

    This paper studies risk selection between public and private health insurance when some, but not all, individuals can opt out of otherwise mandatory public insurance. Using a theoretical model, I show that public insurance is adversely selected when insurers and insureds are symmetrically informed about health-related risks, and that there can be adverse or advantageous selection when insureds are privately informed. Using data from the German Socio-Economic Panel, I find that (i) public insurance is, on balance, adversely selected under the German public health insurance with opt out scheme, (ii) individuals advantageously select public insurance based on risk aversion and residential location, and (iii) there is suggestive evidence of asymmetric information in the market for private health insurance.

    Since its introduction some two decades ago, health risk appraisal (HRA) has become a standard offering in the health promotion repertoire. The technique's distinctive feature is its use of epidemiologic data to generate quantitative risk messages for the client. Yet despite the dedication and considerable investments that have gone into HRA's development, dissemination, and use, there is only limited empirical evidence that these quantitative risk messages have any effect on clients. There do not appear to be any formal studies of HRA's effect on participation in health promotion programs, although increasing recruitment is regarded as a major benefit of using HRA. There are few indications of HRA effects on health beliefs. Most positive reports of effects on behavior change come from uncontrolled studies; several randomized controlled trials have yielded ambiguous findings. Virtually no data exist concerning the impact of the quantitative risk messages that distinguish HRA from other assessment techniques and that have motivated the substantial efforts toward developing and refining HRA. HRA has evident appeal and is probably a useful health education device for middle-class, middle-aged, nonminority clients. It may well have desirable effects on health-related beliefs, attitudes, and behaviors when accompanied by counseling or education, but available evidence has not established its effectiveness. Given the difficulty of obtaining definitive evidence of the effectiveness of HRA and specifically of its use of quantitative risk projections, the need for such evidence is debatable. An adequately funded and reviewed research program to examine whether projections of absolute risk affect knowledge, beliefs, attitudes, and intention to change is recommended as the most fruitful next step. Epidemiologically based HRA procedures that provide feedback in terms of qualitative statements or relative risk may be a promising approach to prospective health assessment. PMID

Work Environment risks such as ergonomics, psycho-social factors and exposure to chemicals and noise, was not given the same attention. The Draugen HSE-Case addresses this weakness and extends all work environment risks. In order to promote line responsibility and commitment, relevant personnel is involved in the Case development. {open_quotes}THESIS{degrees}, a software application, is used to systematize input and to generate reports. The Draugen HSE-case encompasses: HSE risk analyses related to specific activities; Control of risk related to work environment; Established tolerability criteria; Risk reducing measures; Emergency contingency measures; and Requirements for Competence and Follow-up. The development of Draugen HSE-Case is a continuous process. It will serve to minimize the potential of occupational illnesses, raise general awareness, and make occupational health management more cost-effective.

    Irradiated topaz gemstones are currently processed for color improvement by subjecting clear stones to neutron or high-energy electron irradiations, which leads to activation of trace elements in the stones. Assessment of the risk to consumers required the identification and quantification of the resultant radionuclides and the attendant exposure. Representative stones from Brazil, India, Nigeria, Sri Lanka were irradiated and analyzed for gamma ray and beta particle emissions, using sodium iodide and germanium spectrometers; and Geiger-Muller, plastic and liquid scintillation, autoradiography, and thermoluminescent-dosimetry measurement techniques. Based on these studies and other information derived from published literature, dose and related risk estimates were made for typical user conditions. New criteria and methods for routine assays for acceptable release, based on gross beta and gross photon emissions from the stones, were also developed.

    This study investigated the human health risks of trichloroethylene from Industrial Complex A. The excessive carcinogenic risks for central tendency exposure were 1.40 × 10?5 for male and female residents in the vicinity of Industrial Complex A. The excessive cancers risk for reasonable maximum exposure were 2.88 × 10?5 and 1.97 × 10?5 for males and females, respectively. These values indicate that there are potential cancer risks for exposure to these concentrations. The hazard index for central tendency exposure to trichloroethylene was 1.71 for male and female residents. The hazard indexes for reasonable maximum exposure were 3.27 and 2.41 for males and females, respectively. These values were over one, which is equivalent to the threshold value. This result showed that adverse cancer and non-cancer health effects may occur and that some risk management of trichloroethylene from Industrial Complex A was needed. PMID:24278607

    Reliable and comparable analysis of risks to health is key for preventing disease and injury. Causal attribution of morbidity and mortality to risk factors has traditionally been conducted in the context of methodological traditions of individual risk factors, often in a limited number of settings, restricting comparability. In this paper, we discuss the conceptual and methodological issues for quantifying the population health effects of individual or groups of risk factors in various levels of causality using knowledge from different scientific disciplines. The issues include: comparing the burden of disease due to the observed exposure distribution in a population with the burden from a hypothetical distribution or series of distributions, rather than a single reference level such as non-exposed; considering the multiple stages in the causal network of interactions among risk factor(s) and disease outcome to allow making inferences about some combinations of risk factors for which epidemiological studies have not been conducted, including the joint effects of multiple risk factors; calculating the health loss due to risk factor(s) as a time-indexed "stream" of disease burden due to a time-indexed "stream" of exposure, including consideration of discounting; and the sources of uncertainty.

    Health promoters in the United States need to address the challenge of reducing health risks in young adults. The conditions that lead to the largest percentages of early disabilities and deaths are related to lifestyle characteristics. As health care costs continue spiraling upward, many professionals question the use of solely medical solutions to health problems. Health leaders have called for a change in priorities from curing the sick to keeping people well. Reducing health risks will increase longevity, improve quality of life, and reduce health care costs. It is widely believed that during the adolescent and young adult years many important health habits are formed and set. An individual person's health destiny can, in fact, be greatly shaped by the attitudes, behavior, and knowledge adopted during the early years of independence. For these reasons, wellness and self-care programming for college students is vital and worthy of being rigorously explored and evaluated. In this health promotion proposal, peers deliver a Lifestyle Health Planning Program to university students. They can encourage an internal locus of control over health matters and a perception of choice in those they counsel. The peer advisors conduct one-on-one sessions and outreach programs in the subject areas of fitness, nutrition, health-impairing habits, stress management, and sexuality. Promoting self-responsibility during college years can set lifelong positive health habits. A group of trained peer health advisors can be an innovative device to implement a health promotion program in a university setting. PMID:6440207

    In order to provide better sustainable groundwater quality management and minimize the impact of contamination in humans, improved understanding and quantification of the interaction between hydrogeological models, geological site information and human health are needed. Considering the joint influence of these components in the overall human health risk assessment and the corresponding sources of uncertainty aid decision makers to better allocate resources in data acquisition campaigns. This is important to (1) achieve remediation goals in a cost-effective manner, (2) protect human health and (3) keep water supplies clean in order to keep with quality standards. Such task is challenging since a full characterization of the subsurface is unfeasible due to financial and technological constraints. In addition, human exposure and physiological response to contamination are subject to uncertainty and variability. Normally, sampling strategies are developed with the goal of reducing uncertainty, but less often they are developed in the context of their impacts on the overall system uncertainty. Therefore, quantifying the impact from each of these components (hydrogeological, behavioral and physiological) in final human health risk prediction can provide guidance for decision makers to best allocate resources towards minimal prediction uncertainty. In this presentation, a multi-component human health risk-based framework is presented which allows decision makers to set priorities through an information entropy-based visualization tool. Results highlight the role of characteristic length-scales characterizing flow and transport in determining data needs within an integrated hydrogeological-health framework. Conditions where uncertainty reduction in human health risk predictions may benefit from better understanding of the health component, as opposed to a more detailed hydrogeological characterization, are also discussed. Finally, results illustrate how different dose

    The possibility of using in vitro testing to determine the equivalence of risk for various occupational groups is discussed. In the absence of epidemiological evidence or relevant animal in vivo bioassays on which to determine the health effects of specific occupational exposures, it is proposed to use similarities in the in vitro response to substances with known (or strongly suspected) and unknown risk to demonstrate their risk equivalence. Identification and evaluation of a high risk "hot spot" due to exposure to Cr(VI) for stainless steel welders is discussed in terms of recent developments in collection, analysis and bioassay of welding fumes.

    Across the lifespan, attention deficit/hyperactivity disorder (ADHD) is associated with increased health risk behaviors including substance abuse, binge eating and obesity, and unsafe sexual behavior. These risks are directly linked to the neurocognitive deficits associated with ADHD, and are also mediated by the cascade of psychosocial impairments and stressors caused by ADHD across development. However, little is known about optimal approaches to improve health outcomes in this high-risk population. This topical review provides an overview of health risks associated with ADHD and the limited existing research relevant to health promotion for children and adolescents with ADHD. Future research questions and implications for clinicians are also addressed-especially how psychologists and medical practitioners may improve child health through early screenings, increasing medication adherence, and treating psychosocial impairments.

    Superfund conjures up images of hazardous waste sites, which EPA is spending billions of dollars to remediate. One of the law's most worrisome effects is that it drains enormous economic resources without returning commensurate benefits. In a Sept. 1, 1991, front page article in The New York Times, experts argued that most health dangers at Superfund sites could be eliminated for a fraction of the billions that will be spent cleaning up the 1,200 high-priority sites across the country. Even EPA has suggested that the Superfund program may receive disproportionate resources, compared with other public health programs, such as radon in houses, the diminishing ozone layer and occupational diseases. Public opinion polls over the last decade consistently have mirrored the public's vast fear of hazardous waste sites, a fear as great as that held for nuclear power plants. Fear notwithstanding, the high cost of chosen remedies at given sites may have less to do with public health goals than with the method EPA uses to translate them into acceptable contaminant concentrations in soil, groundwater and other environmental media.

    1991-06-01

    Radiation-produced blue topaz, indistinguishable from natural blue topaz, is produced by several different techniques. Published information on radionuclides present, activity levels, equipment necessary to detect activated nuclides and dosimetric assessment is lacking. Using a 60 megawatt nuclear reactor, fifty-one samples of colorless topaz from Nigeria, Sri Lanka, India and Brazil were irradiated with thermal and fast neutron fluences ranging from 1.8 times 10 13 to 9.2 times 1018 neutrons cm^{-2}. Seventeen MeV electrons produced by a linear accelerator were also used to irradiate 36 colorless topaz from the same countries. Gamma ray or positron-emitting nuclides were identified using calibrated well-type NaI or germanium detectors. For germanium detectors having relative efficiencies of approximately 20 percent, an analysis time of one hour or more was needed. Geiger Mueller (G-M) detectors, scintillators (plastic and liquid), gas flow proportional counters, a ZnS detector and autoradiography techniques were used to measure charged particle activity. Isotopes produced from neutron activation included 182Ta, ^ {59}Fe, 46Sc, 51Cr, 54Mn, 124Sb, ^{32 }P, 77As, ^ {183}Ta, 77Ge, 72Ga, and ^{24 }Na. Possible nuclides produced from 17 MeV electron treatment include ^{68 }Ga, 64Cu, ^ {49}Cr, and 18F. Positive identification of the electron activated nuclides was not possible because of the short half-lives involved (<1 day). Of the possible pure beta emitters activated during neutron bombardment, 32P and 35S are the most likely to be produced. The identification of 32P was made using a three point beta absorption analysis with a G-M detector. Skin and breast cancer risk estimates were calculated for various sized topaz containing NRC exempt concentration levels. When compared to a negligible individual risk level (NIRL) of 10^{-7}, the risk of an irradiated topaz in contact with the skin or three inches from breast tissue was a small fraction of the NIRL.

    The article studies the public health potential risk originated from water consumption and estimated on the basis of the groundwater chemical composition. We have processed the results of chemical groundwater analysis in different aquifers of Tomsk district (Tomsk Oblast, Russia). More than 8400 samples of chemical groundwater analyses were taken during long-term observation period. Human health risk assessment of exposure to contaminants in drinking water was performed in accordance with the risk assessment guidance for public health concerning chemical pollution of the environment (Russian reference number: 2.1.10.1920-04-M, 2004). Identified potential risks were estimated for consuming water of each aquifer. The comparative analysis of water quality of different aquifers was performed on the basis of the risk coefficient of the total non-carcinogenic effects. The non-carcinogenic risk for the health of the Tomsk district population due to groundwater consumption without prior sanitary treatment was admitted acceptable. A rather similar picture is observed for all aquifers, although deeper aquifers show lower hazard coefficients.

    The major food safety risks are not eating a healthy diet, and failure to avoid foodborne illness. Over one billion people in the world suffer from food insecurity and malnutrition. Nutritionally enhanced transgenic crops such as Golden Rice are one potential strategy for reducing malnutrition in the world. Transgenic crops are subjected to a rigorous pre-market safety assessment. The safety of novel proteins and other products is established, and through compositional analysis and animal studies, the safety of any observed changes is evaluated. These studies provide evidence that the new product is as safe as, or safer than, comparable varieties. It must be asked, however, if this rigorous analysis is necessary, because unregulated crops produced by other breeding methods also undergo genetic changes and contain unintended effects. Golden Rice poses infinitesimally small, if any, risk to consumers whilst it has the potential to spare millions of lives each year. However, because it is a transgenic crop, it cannot be deployed without years of expensive pre-market safety review. Paradoxically, if Golden Rice had been produced by less precise conventional methods of breeding, it would already be in the hands of poor farmers. It is concluded that the hyper-precautionary regulatory process applied to transgenic crops works to the extreme disadvantage of the hungry and the poor. PMID:20621653

    Introduction This paper studies the relationship between the risk of child social exclusion, as measured by the Child Social Exclusion (CSE) index and its individual domains, and child health outcomes at the small area level in Australia. The CSE index is Australia’s only national small-area index of the risk of child social exclusion. It includes five domains that capture different components of social exclusion: socio-economic background, education, connectedness, housing and health services. Methods The paper used data from the National Centre for Social and Economic Modelling (NATSEM), University of Canberra for the CSE Index and its domains and two key Australian Institute of Health and Welfare (AIHW) data sources for the health outcome measures: the National Hospital Morbidity Database and the National Mortality Database. Results The results show positive associations between rates of both of the negative health outcomes: potentially preventable hospitalisations (PPH) and avoidable deaths, and the overall risk of child social exclusion as well as with the index domains. This analysis at the small-area level can be used to identify and study areas with unexpectedly good or bad health outcomes relative to their estimated risk of child social exclusion. We show that children’s health outcomes are worse in remote parts of Australia than what would be expected solely based on the CSE index. Conclusions The results of this study suggest that developing composite indices of the risk of child social exclusion can provide valuable guidance for local interventions and programs aimed at improving children’s health outcomes.

    Hypogonadism is prevalent in older men and testosterone replacement therapy (TRT) for older hypogonadal men is a promising therapy. However, a number of important clinical concerns over TRT safety remain unsolved due to a lack of large-scale randomized clinical trials directly comparing the health risks of untreated hypogonadism vs long-term use of TRT. Meta-analyses of clinical trials of TRT as of 2010 have identified three major adverse events resulting from TRT: polycythemia, an increase in prostate-related events, and a slight reduction in serum high-density lipoprotein cholesterol. There are other purported health risks but their incidence can be neither confirmed nor denied based on the small number of subjects that have been studied to date. Furthermore, subsequent literature is equivocal with regard to the safety and utility of TRT and this topic has been subject to contentious debate. Since January 2014, the United States Food and Drug Administration has released two official announcements regarding the safety of TRT and clinical monitoring the risks in TRT users. Additionally, the health risks related to the clinical presentation of low or declining testosterone levels not been resolved in the current literature. Because TRT is prescribed in the context of putative risks resulting from reduced testosterone levels, we reviewed the epidemiology and reported risks of low testosterone levels. We also highlight the current information about TRT utilization, the risks most often claimed to be associated with TRT, and current or emerging alternatives to TRT. PMID:25879005

    Background: Research project risks are uncertain contingent events or situations that, if transpire, will have positive or negative effects on objectives of a project. The Management of Health and Safety at Work (MHSW) Regulations 1999 require all employers and the self-employed persons to assess the risks from their work on anyone who may be affected by their activities. Risk assessment is the first step in risk-management procedure, and due to its importance, it has been deemed to be a vital process while having a unique place in the researchbased management systems. Methods: In this research, a two-pronged study was carried out. Firstly, health and safety issues were studied and analyzed by means of ISO 14121. Secondly, environmental issues were examined with the aid of Failure Mode and Effect Analysis. Both processes were utilized to determine the risk level independently for each research laboratory and corrective measure priorities in each field (laboratory). Results: Data analysis showed that the total main and inherent risks in laboratory sites reduced by 38% to 86%. Upon comparing the average risk levels before and after implementing the control and protective actions utilizing risk management approaches which were separate from health, safety and environmental aspects, a highly effective significance (p<0.001) was obtained for inherent risk reduction. Analysis of health, safety and environmental control priorities with the purpose of comparing the ratio of the number of engineering measures to the amount of management ones showed a relatively significant increase. Conclusion: The large number of engineering measures was attributed to the employment of a variety of timeworn machinery (old technologies) along with using devices without basic protection components.

  5. The age of risk: risk perception and determination following the Mental Health Act 2007.

    Reforms to the mental health law framework for England and Wales, which were introduced by the Mental Health Act 2007, are now having a practical effect on day-to-day mental health decision-making. The 2007 Act amends the Mental Health Act 1983, which governs the compulsory hospitalisation and treatment of people with mental disorder; and represents the culmination of a protracted and controversial reform process which has spanned much of the last 15 years. One of the key foci in the 2007 Act is the question of the risk posed by the patient, primarily to others; a result of both the social and political impetus behind the reform process and mounting public anxiety at the management of the mentally disordered. The new Act seeks, as with past legislation, to find the elusive balance between protecting and facilitating the individual's autonomy while also providing an effective framework for the wider public right to protection. The 2007 Act solidifies the dominance of risk by providing a legitimating framework in which risk can be assessed, monitored, and managed. This attitudinal change is demonstrated by the gradual and almost insidious adoption of risk terminology within the practical decision-making setting and the increasing use of risk assessment and management tools. This article is informed by an empirical study which examined individual professional and institutional responses to the mental health legislation in relation to risk. It examines whether the amended legislative framework amplifies risk as an increasingly dominant concern within decision-making. The paper then goes on to consider how decision-makers use risk to assist with their daily roles. Extrapolated from data obtained through the study, several models of risk determination are then discussed. Finally, some thought is given to whether the extension of the risk concept has the potential to become more fundamental within the organisation and legitimisation of mental health care.

    Data from the Health Promotion and Disease Prevention Questionnaire, part of the 1985 National Health Interview Survey, were used to report workers' perceptions of occupational risk in their present jobs. This information will be used to monitor progress between 1985 and 1990 toward achieving broad goals in health promotion and disease prevention. The proportions of currently employed persons who perceived exposure to health-endangering substances, work conditions, or risks of injuries were reported for age, race, sex, and occupation groups. Occupational groups were further characterized by the proportion of men and women who reported specific exposures (such as exposure to chemicals or to loud noise) and specific health consequences of exposure (such as risk of developing cancer or hearing impairment). Greater proportions of men than women reported perceived risk from exposure to health-endangering substances, work conditions, and injuries in their present job. Also, a greater proportion of workers perceived risk of injury in their present job than other occupational risk categories. The greatest proportions of perceived exposure to occupational risk were reported by farm operators and managers, police and firefighters, and by workers in forestry and fishing occupations. Among workers reporting perceived exposures, chemicals, noise, and risk of injuries from vehicles were cited by the greatest proportion of workers, as were such health consequences as lung and respiratory problems and hearing impairment. Data from this study may be used to target employment groups for health promotion or education and to develop indepth studies of specific occupational groups to reduce or prevent risk at the worksite.

    Although there is substantial evidence that health risk behaviors increase risks of premature morbidity and mortality, little is known about the multiple health risk behaviors in Chinese college students. Here, we investigated the prevalence of multiple health risk behaviors and its relation to mental health among Chinese college students. A cross-sectional study was conducted in Wuhan, China from May to June 2012. The students reported their health risk behaviors using self-administered questionnaires. Depression and anxiety were assessed using the self-rating depression scale and self-rating anxiety scale, respectively. A total of 2422 college students (1433 males) aged 19.7 ± 1.2 years were participated in the study. The prevalence of physical inactivity, sleep disturbance, poor dietary behavior, Internet addiction disorder (IAD), frequent alcohol use and current smoking was 62.0, 42.6, 29.8, 22.3, 11.6 and 9.3%, respectively. Significantly increased risks for depression and anxiety were found among students with frequent alcohol use, sleep disturbance, poor dietary behavior and IAD. Two-step cluster analysis identified two different clusters. Participants in the cluster with more unhealthy behaviors showed significantly increased risk for depression (odds ratio (OR): 2.21; 95% confidence interval (CI): 1.83, 2.67) and anxiety (OR: 2.32; 95% CI: 1.85, 2.92). This study indicates that a relatively high prevalence of multiple health risk behaviors was found among Chinese college students. Furthermore, the clustering of health risk behaviors was significantly associated with increased risks for depression and anxiety. PMID:26222809

    As China's capital city, Beijing is experiencing unprecedented environmental degradation accompanied by complex interactions between urbanization and global environmental change, which places human health at risk on a large spatial and temporal scale. For sustainable development that supports environmental and human health in Beijing and during the upcoming "green" Olympic games in 2008, experts and political leaders must acknowledge the urgent health risks from environmental changes related to urbanization. A range of urban health hazards and associated health risks in Beijing result from a variety of factors including heat islands, air pollution, water crisis, soil pollution, infectious diseases, and urban consumerism; in addition, some hazardous health conditions are associated with inequality in living and working conditions. The authors suggest 2 main areas for policy action and research direction: (1) the need to get full-scale information related to environmental monitoring data and health data (and then to provide new methodological approaches and techniques to implement interventions) and (2) the need for effective cooperation among different sectors.

    The Health and Environmental Sciences Institute (HESI)-coordinated Risk Assessment in the 21st Century (RISK21) project was initiated to develop a scientific, transparent, and efficient approach to the evolving world of human health risk assessment, and involved over 120 participants from 12 countries, 15 government institutions, 20 universities, 2 non-governmental organizations, and 12 corporations. This paper provides a brief overview of the tiered RISK21 framework called the roadmap and risk visualization matrix, and articulates the core principles derived by RISK21 participants that guided its development. Subsequent papers describe the roadmap and matrix in greater detail. RISK21 principles include focusing on problem formulation, utilizing existing information, starting with exposure assessment (rather than toxicity), and using a tiered process for data development. Bringing estimates of exposure and toxicity together on a two-dimensional matrix provides a clear rendition of human safety and risk. The value of the roadmap is its capacity to chronicle the stepwise acquisition of scientific information and display it in a clear and concise fashion. Furthermore, the tiered approach and transparent display of information will contribute to greater efficiencies by calling for data only as needed (enough precision to make a decision), thus conserving animals and other resources.

    In the face of limited resources and an aging population with increasingly care needs, healthcare systems must identify community-dwelling older adults with mental health problems at higher risk of adverse outcomes such as institutionalization, hospitalization and death, in order to deliver timely and efficient care. The objectives of this study were to assess the prevalence of mental health concerns and the associated perceived risk of adverse outcomes in a large sample of older patients in primary care (PC). We trained general practitioners and nurses to use the Risk Instrument for Screening in the Community to rank perceived risk of mental health concerns (including neurocognitive and mood disorders) from 1 (mild) to 3 (severe). The mean age of the 4499 people assessed was 76.3 years (SD = 7.3) and 2645 (58.8%) were female. According to the PC team 1616 (35.9%) were perceived to have mental health concerns of whom 847 (52.4%) were mild, 559 (34.6%) were moderate and 210 (13%) were severe. Patients with mental health concerns had higher odds of perceived risk of adverse outcomes (OR = 2.22, 95% CI 1.83–2.69 for institutionalization; OR = 1.66, 95% CI 1.41–1.94 for hospitalization; OR = 1.69, 95% CI 1.42–2.01 for death). These results suggest a high prevalence of mental health concerns among older adults and supports the need for early identification of patients at high-risk of adverse healthcare outcomes.

    The 1980s will be remembered by forest professionals as a decade of intense and widespread societal concern for the vitality and integrity of forest systems. Daily reports of tropical deforestation and temperate forest decline have heightened social consciousness of forest health. It is therefore appropriate, as we enter the 1990s, to assess the health of our forests and propose new initiatives in this critically important area. Making generalizations about the health of North American forests is difficult because of the extraordinary diversity of forests, management regimes, and stress factors. This overview article summarizes forest health fundamentals, significant health risks, and priorities in future forest health management for temperate forests of the United States.

    The consequences of pandemic influenza for vulnerable populations will depend partly on the effectiveness of health risk communications. Strategic planning should fully consider how life circumstances, cultural values, and perspectives on risk influence behavior during a pandemic. We summarize recent scientific evidence on communication challenges and examine how sociocultural, economic, psychological, and health factors can jeopardize or facilitate public health interventions that require a cooperative public. If ignored, current communication gaps for vulnerable populations could result in unequal protection across society during an influenza pandemic. We offer insights on communication preparedness gleaned from scientific studies and the deliberations of public health experts at a meeting convened by the Centers for Disease Control and Prevention, May 1 and 2, 2008.

    Unawareness of the health risks of beryllium resulted in a decade of unmitigated exposure of several thousand workers and numerous cases of beryllium disease in employees and nearby residents. Subsequent adoption of exposure limits and their implementation with effective technical controls reduced the occurrence of new cases, which were mainly due to accidental exposures, to a minimum. The fact that continuously growing production and consumption did not alter this trend demonstrates the effectiveness of the present threshold limit value. It shows that the potential health hazard can be well contained and that beryllium can be produced and fabricated without undue risk to employees or the general public.

    Background The prevalence and severity of obesity have increased among children and adolescents. While the medical and psychosocial consequences of youth obesity have been well-documented, less information exists on the association of overweight/obesity with health risk behaviors, which are considered to be a primary threat to adolescent health. Objectives This study examined the association of overweight and obesity with health-risk behaviors among U.S. youth. Methods Self-reported height and weight, substance use, violence and bullying were assessed in a nationally representative sample of students aged 11 to 17 years (N=7825) who participated in the 2005/6 Health Behaviors in School-Aged Children survey. Data were analyzed in 2009. Results Significant gender and age differences in the relationship of overweight/obesity with risk behaviors were observed. Overweight and obesity were significantly associated with substance use among girls only: frequent smoking and drinking were associated with overweight and obesity among younger girls, whereas they were associated with obesity among older girls. Frequent smoking and cannabis use were associated with overweight among younger girls only. Relationships between violent behavior and overweight/obesity were mainly observed among boys: Younger obese boys were more likely to be victims of bullying, whereas older obese boys were more likely to carry weapons, compared to boys of normal weight. Conclusions Overweight and obese youth are at risk of developing health compromising behaviors which may compound medical and social problems associated with excess weight. PMID:20171527

    With the way cleared for increased use of the fuel additive methylcyclopentadienyl manganese tricarbonyl (MMT) in the United States, the issue of possible public health impacts associated with this additive has gained greater attention. In assessing potential health risks of particulate Mn emitted from the combustion of MMT in gasoline, the U.S. Environmental Protection Agency not only considered the qualitative types of toxic effects associated with inhaled Mn, but conducted extensive exposure-response analyses using various statistical approaches and also estimated population exposure distributions of particulate Mn based on data from an exposure study conducted in California when MMT was used in leaded gasoline. Because of limitations in available data and the need to make several assumptions and extrapolations, the resulting risk characterization had inherent uncertainties that made it impossible to estimate health risks in a definitive or quantitative manner. To support an improved health risk characterization, further investigation is needed in the areas of health effects, emission characterization, and exposure analysis. PMID:9539013

    2005-01-01

    Plant proteins have a reduced content of essential amino acids in comparison to animal proteins. A significant reduction of limiting amino acids (methionine, lysine, tryptophan) means lower protein synthesis. In subjects with predominant or exclusive consumption of plant food a higher incidence of hypoproteinemia due to significant reduction of methionine and lysine intakes was observed. On the other hand, lower intake of these amino acids provides a preventive effect against cardiovascular disease via cholesterol regulation by an inhibited hepatic phospholipid metabolism. Vegetarians have a significantly higher intake of non-essential amino acids arginine and pyruvigenic amino acids glycine, alanine, serine. When plant protein is high in non-essential amino acids, down-regulation of insulin and up-regulation of glucagon is a logical consequence. The action of glucagon in the liver is mediated by stimulation of adenyl cyclase that raises cyclic-AMP (adenosine-3,5-monophosphate) concentrations. Cyclic-AMP down-regulates the synthesis of a number of enzymes required for de novo lipogenesis and cholesterol synthesis, up-regulates key gluconeogenic enzymes and the LDL receptors and decreases the IGF-1 activity (insulin-like growth factor). Cyclic-AMP thus provides a reduction of atherosclerosis risk factors as well as a retardation of cancer development. A sufficient consumption of plant proteins has the protective effects against chronic degenerative diseases (Tab. 2, Ref. 26). PMID:16201743

    Water quality has deteriorated in the upper Olifants River system, South Africa, as a result of land use activities which include mining, agriculture and industries. A health risk assessment was conducted from 2009 to 2011 in the catchment to determine the possible risks local communities face from various pollutants such as microbials, heavy metals and oestrogen in the river water and vegetation. Aluminium and manganese accumulated in plants and vanadium and aluminium concentrations found in selective water samples posed significant health risks when consumed. A quantitative microbial risk assessment revealed that the combined risk of infection ranged from 1 to 26 percent with the Norovirus posing the overall greatest health risk. The anticipated disability adjusted life years resulting from drinking untreated water from these sites are in the order of 10,000 times greater than what is considered acceptable. The oestradiol activity, caused by endocrine disrupting compounds in the water, measured above the trigger value of 0.7ngL(-1). Impoverished communities in the area, who partially depend on river water for potable and domestic use, are exposed to immune-compromising metals that increase their probability of infection from waterborne diseases caused by the excess microbial pathogens in the contaminated surface water.

    2009-01-01

    Summary The tracking of sentinel health events in humans in order to detect and manage disease risks facing a larger population is a well accepted technique applied to influenza, occupational conditions, and emerging infectious diseases. Similarly, animal health professionals routinely track disease events in sentinel animal colonies and sentinel herds. The use of animals as sentinels for human health threats, or of humans as sentinels for animal disease risk, dates back at least to the era when coal miners brought caged canaries into mines to provide early warning of toxic gases. Yet the full potential of linking animal and human health information to provide warning of such “shared risks” from environmental hazards has not been realized. Reasons appear to include the professional segregation of human and animal health communities, the separation of human and animal surveillance data, and evidence gaps in the linkages between human and animal responses to environmental health hazards. The One Health initiative and growing international collaboration in response to pandemic threats, coupled with development the fields of informatics and genomics, hold promise for improved sharing of knowledge about sentinel events in order to detect and reduce environmental health threats shared between species.

    2013-04-15

    Traffic congestion increases vehicle emissions and degrades ambient air quality, and recent studies have shown excess morbidity and mortality for drivers, commuters and individuals living near major roadways. Presently, our understanding of the air pollution impacts from congestion on roads is very limited. This study demonstrates an approach to characterize risks of traffic for on- and near-road populations. Simulation modeling was used to estimate on- and near-road NO2 concentrations and health risks for freeway and arterial scenarios attributable to traffic for different traffic volumes during rush hour periods. The modeling used emission factors from two different models (Comprehensive Modal Emissions Model and Motor Vehicle Emissions Factor Model version 6.2), an empirical traffic speed-volume relationship, the California Line Source Dispersion Model, an empirical NO2-NOx relationship, estimated travel time changes during congestion, and concentration-response relationships from the literature, which give emergency doctor visits, hospital admissions and mortality attributed to NO2 exposure. An incremental analysis, which expresses the change in health risks for small increases in traffic volume, showed non-linear effects. For a freeway, "U" shaped trends of incremental risks were predicted for on-road populations, and incremental risks are flat at low traffic volumes for near-road populations. For an arterial road, incremental risks increased sharply for both on- and near-road populations as traffic increased. These patterns result from changes in emission factors, the NO2-NOx relationship, the travel delay for the on-road population, and the extended duration of rush hour for the near-road population. This study suggests that health risks from congestion are potentially significant, and that additional traffic can significantly increase risks, depending on the type of road and other factors. Further, evaluations of risk associated with congestion must

We carry out a cross-sectional analysis of 5573 adults who participated and had indicated that they needed to state their health description in the three years prior to the phase 2007 World Health Organization, a study on Global Ageing and Adult health (SAGE) conducted in Ghana. The ordinal logistic regression model was employed for analysis using R. The results suggest that, there is incontrovertible evidence showing a strong relationship between preventive health behaviors and health status of Ghanaians. Again, the lifestyle of Ghanaians clearly manifests in their positive correlation with the good and moderate health state due to the high percentage (38.96% and 39.04%) respectively. The outcome points to a potential link with the Ghanaian social and health policies. PMID:23985114

    Despite national objectives for extending health promotion programs to blue-collar workers and to small work sites, baseline behavior information for planning such programs is lacking. This study seeks to describe the health risks and norms specific to a population of male, blue-collar gas pipeline workers in remote sites. These workers (n = 395) completed a health risk appraisal and a "health gauge" survey designed to measure nutrition, physical activity, tobacco use, participatory patterns in health-enhancing activities, group norms, and change efforts. Selected behaviors were similar to those of other Texas men (eg, smoking 27% versus 26%) although others were not (eg, smokeless tobacco 18% versus 8%). Multivariate analysis confirmed the relationship of friends' behavior patterns, risk-taking, and interpersonal experience to four lifestyle health behaviors. With 75% or more of workers expressing an interest in various programs, the findings suggest that programming for this population can be successful if tailored to current behaviors and the worksite culture.

    2016-01-01

    Approximately 2.3 million children in the United States live separately from both parents; 70-90% of those children live with a relative. Compared with children living with one or both parents, children in nonparental care are in poorer health, are at heightened risk for experiencing disruptions and instability in caregiving, and are vulnerable to other social antecedents of child health (e.g., neglect, poverty, maltreatment). Given the significant impact of adversity in childhood on health across the lifespan, which is increased among children in nonparental care, it is informative to consider the health risks of children living in nonparental care specifically. Research examining the contributions of poverty, instability, child maltreatment, and living in nonparental care, including meta-analyses of existing studies, are warranted. Longitudinal studies describing pathways into and out of nonparental care and the course of health throughout those experiences are also needed. Despite these identified gaps, there is sufficient evidence to indicate that attention to household structure is not only relevant but also essential for the clinical care of children and may aid in identifying youth at risk for developing poor health across the lifespan.

    Background: The National Health Insurance Scheme (NHIS), operated majorly in Nigeria by health maintenance organisations (HMOs), took off formally in June 2005. In view of the inherent risks in the operation of any social health insurance, it is necessary to efficiently manage these risks for sustainability of the scheme. Consequently the risk-management strategies deployed by HMOs need regular assessment. This study assessed the risk management in the Nigeria social health insurance scheme among HMOs. Materials and Methods: Cross-sectional survey of 33 HMOs participating in the NHIS. Results: Utilisation of standard risk-management strategies by the HMOs was 11 (52.6%). The other risk-management strategies not utilised in the NHIS 10 (47.4%) were risk equalisation and reinsurance. As high as 11 (52.4%) of participating HMOs had a weak enrollee base (less than 30,000 and poor monthly premium and these impacted negatively on the HMOs such that a large percentage 12 (54.1%) were unable to meet up with their financial obligations. Most of the HMOs 15 (71.4%) participated in the Millennium development goal (MDG) maternal and child health insurance programme. Conclusions: Weak enrollee base and poor monthly premium predisposed the HMOs to financial risk which impacted negatively on the overall performance in service delivery in the NHIS, further worsened by the non-utilisation of risk equalisation and reinsurance as risk-management strategies in the NHIS. There is need to make the scheme compulsory and introduce risk equalisation and reinsurance. PMID:25298605

    The objective of this study was to explore Mexican adolescents' perceptions of environmental health risks in contaminated urban areas, and to test the environmental photography technique as a research tool for engaging adolescents in community-based health research. The study was conducted with 74 adolescents from two communities in the city of San Luis Potosi, Mexico. Participants were provided with disposable cameras and asked to take photographs of elements and situations which they believed affected their personal health both at home and outside their homes. They were also asked to describe each photograph in writing. Photographs and written explanations were analyzed by using quantitative and qualitative content analysis. Risk perception plays a crucial role in the development of Risk Communication Programs (RCPs) aimed at the improvement of community health. The photography technique opens up a promising field for environmental health research since it affords a realistic and concise impression of the perceived risks.

  11. Health risks from increases in methylmercury exposure.

    1985-01-01

    Our present knowledge of the human health effects of methylmercury exposure is derived from study of major outbreaks of human poisonings in Japan and Iraq and experimental studies on primates. Methylmercury readily passes through such physiological barriers as the blood-brain barrier, blood-testes barrier, and the placenta. Its major pathological effects are on the nervous and reproductive systems and the developing embryo/fetus. The neurotoxicity of methylmercury is well established in both humans and non-human primates. Lesions in the cerebral and cerebellar gray matter consist of necrosis and lysis of neurons, phagocytosis and gliosis. The changes are most prominent in the deep sulci and may have a vascular component. A late effect is cerebral atrophy. At high dose levels the liver, kidneys, and other organs may also have degenerative changes. Although not yet described in humans, a major effect of exposure of female primates is an adverse effect on pregnancy. Maternal female M. fascicularis blood mercury levels above 1 ppm are associated with a decreased pregnancy rate and increased abortion rate. To date our experimental data lack sufficient numbers to detect infrequent pregnancy effects below 1 ppm. Preliminary studies also reveal that methylmercury may also decrease the number and function (swim speed) of sperm. Both human and primate studies demonstrate deleterious effects of methylmercury on the developing embryo/fetus. Autopsies on human and primate infants reveal retarded brain development and the occurrence of a cerebral palsy-like behavior in the newborns, whereas the mother may be free of signs and symptoms of methylmercury toxicity. The fetal blood level of mercury is higher than the maternal level.(ABSTRACT TRUNCATED AT 250 WORDS) Images FIGURE 1. FIGURE 2. FIGURE 3. FIGURE 5. PMID:3908085

  13. Environmental health risk assessment and management for global climate change

    NASA Astrophysics Data System (ADS)

    Carter, P.

    2014-12-01

    This environmental health risk assessment and management approach for atmospheric greenhouse gas (GHG) pollution is based almost entirely on IPCC AR5 (2014) content, but the IPCC does not make recommendations. Large climate model uncertainties may be large environmental health risks. In accordance with environmental health risk management, we use the standard (IPCC-endorsed) formula of risk as the product of magnitude times probability, with an extremely high standard of precaution. Atmospheric GHG pollution, causing global warming, climate change and ocean acidification, is increasing as fast as ever. Time is of the essence to inform and make recommendations to governments and the public. While the 2ºC target is the only formally agreed-upon policy limit, for the most vulnerable nations, a 1.5ºC limit is being considered by the UNFCCC Secretariat. The Climate Action Network International (2014), representing civil society, recommends that the 1.5ºC limit be kept open and that emissions decline from 2015. James Hansen et al (2013) have argued that 1ºC is the danger limit. Taking into account committed global warming, its millennial duration, multiple large sources of amplifying climate feedbacks and multiple adverse impacts of global warming and climate change on crops, and population health impacts, all the IPCC AR5 scenarios carry extreme environmental health risks to large human populations and to the future of humanity as a whole. Our risk consideration finds that 2ºC carries high risks of many catastrophic impacts, that 1.5ºC carries high risks of many disastrous impacts, and that 1ºC is the danger limit. IPCC AR4 (2007) showed that emissions must be reversed by 2015 for a 2ºC warming limit. For the IPCC AR5 only the best-case scenario RCP2.6, is projected to stay under 2ºC by 2100 but the upper range is just above 2ºC. It calls for emissions to decline by 2020. We recommend that for catastrophic environmental health risk aversion, emissions decline

    BACKGROUND Risk assessment of patients in general practice is a challenging area of clinical practice. Competing interests of managing patient wishes, consideration of duty to warn others and invoking the Mental Health Act while practising in a medicolegally accountable manner can be difficult. OBJECTIVE This article summarises the risk assessment of patients with possible mental disorders and provides suggestions regarding measures that may be undertaken to manage risk in psychiatric emergencies. DISCUSSION The evidence of effectiveness for risk assessment interventions in acute settings is limited. While it is not possible for general practitioners to predict the future, and particularly to predict fatal outcomes, they can be expected to meet a standard of care that identifies those at risk and provide an acceptable clinical response.

    The negative impact of urbanization on public health is obvious. However; due to the comprehensiveness and polymorphicity of its manifestations there are not established criteria for them. Health risk methodology allows, in principle, to obtain quantitative indices of the separate results of the impact on the health status of the citizens of metropolis that can be extremely effective in this area. The total cross-media riskfrom traffic pollution, drinking water quality, open ponds, noise, etc. permits to use of hygiene criteria in urban planning, insurance, taxation, etc. PMID:26031033

    The operational role of the occupational health physician in the assessment and management of health risks related to night work. Night work, in the last 30-40 years, has been extended to almost all areas of employment. The potential effects on workers' health--related to the disruption of circadian rhythms--are now well defined and studied in the Literature. All issues about the protection of safety and health for night workers are governed by the Italian Legislative Decree no. 66/2003 and subsequent amendments. The management of night work hasn't been included into the main Law on Occupational Safety and Health (Italian Legislative Decree no. 81/2008 and subsequent amendments) and a coordination between the two disciplines is desirable. The occupational health physician, as a global consultant for the protection of all health issues into a company, has to evaluate the potential effects of night work on health, both individually and as a group of workers. In this way, the physician may use either traditional tools (history, physical examination, blood tests) or innovative tools (questionnaires, health promotion programs, interventions on shift schedules). In the management of night work is useful to employ schedules that respect both psychophysical integrity and social welfare of workers and the needs of the production. The occupational health physician plays a significant role in information and training of workers, both individually and as a group of workers, and in the organization of health promotion programs (whit a voluntary participation by the workers).

  19. Communicating Health Risks under Pressure: Homeland Security Applications

    2006-07-01

    The U.S. Environmental Protection Agency's (EPA) Office of Research and Development (ORD) Threat and Consequence Assessment Division (TCAD) within the National Homeland Security Research Center (NHSRC) has developed a tool for rapid communication of health risks and likelihood of exposure in preparation for terrorist incidents. The Emergency Consequence Assessment Tool (ECAT) is a secure web-based tool designed to make risk assessment and consequence management faster and easier for high priority terrorist threat scenarios. ECAT has been designed to function as 'defensive play-book' for health advisors, first responders, and decision-makers by presenting a series of evaluation templates for priority scenarios that can be modified for site-specific applications. Perhaps most importantly, the risk communication aspect is considered prior to an actual release event, so that management or legal advisors can concur on general risk communication content in preparation for press releases that can be anticipated in case of an actual emergency. ECAT serves as a one-stop source of information for retrieving toxicological properties for agents of concern, estimating exposure to these agents, characterizing health risks, and determining what actions need to be undertaken to mitigate the risks. ECAT has the capability to be used at a command post where inputs can be checked and communicated while the response continues in real time. This front-end planning is intended to fill the gap most commonly identified during tabletop exercises: a need for concise, timely, and informative risk communication to all parties. Training and customization of existing chemical and biological release scenarios with modeling of exposure to air and water, along with custom risk communication 'messages' intended for public, press, shareholders, and other partners enable more effective communication during times of crisis. For DOE, the ECAT could serve as a prototype that would be amenable to

    Cancer risk perceptions and cancer worry are shaped by race/ethnicity, and social, economic, and environmental factors, which in turn shape health decision-making. A paucity of studies has explored risk perceptions and worry in metropolitan areas with disparate environmental conditions and cancer outcomes. This study examined perceptions of cancer risk, neighborhood environmental health risks, and risk-reducing health behaviors among Blacks. A 59-item survey was administered to respondents in Metropolitan Charleston, South Carolina from March to September 2013. A convenience sample of males and females was recruited at local venues and community events. Descriptive statistics, bivariate analyses (Chi square tests), and logistic regression models were estimated using SAS 9.3 software. Respondents (N = 405) were 100% Black, 81% female (n = 323), and ranged from 18 to 87 years of age (M = 49.55, SD = 15.27). Most respondents reported lower perceptions of cancer risk (37%) and equated their cancer beliefs to direct or indirect (i.e. personal or family) experiences. Low perceived cancer risk (absolute risk) was significantly associated (p < .05) with non-alcohol consumption, having a colon cancer screening test, being female, and being age 25-44 or 45-64. Cancer worry was significantly associated (p < .05) with being a current smoker, having a "fair" diet, non-alcohol consumption, and having any colon cancer screening test. Perceived cancer risk is an important indicator of health behaviors among Blacks. Direct or indirect experiences with cancer and/or the environment and awareness of family history of cancer may explain cancer risk perceptions. PMID:25315713

    Virtually created panic among health care workers about pandemic acquired immune deficiency syndrome prompted us to review the scientific literature to investigate the risk of human immunodeficiency virus (HIV) transmission in the daily works of health care workers, especially surgeons and anesthesiologists. In this review, we report worldwide valuations of the number of HIV infections that may occur from unsafe daily work in health care. We also present how to minimize the risk of infection by taking precautions and how to utilize postexposure prophylaxis in accordance with the latest reports of the Centers for Disease Control and Prevention. HIV-infected patients will be aging, and most of them will become the candidates for procedures such as major vascular reconstruction and artery bypass grafting, where the risks of blood contact and staff injury are high. For these reasons, all health care workers need to know how to prevent, and fight following the accidental exposure to HIV. PMID:27366077

    We examined the association of muscular fitness with psychological positive health, health complaints, and health risk behaviors in 690 (n = 322 girls) Spanish children and adolescents (6-17.9 years old). Lower body muscular strength was assessed with the standing long jump test, and upper-body muscular strength was assessed with the throw basketball test. A muscular fitness index was computed by means of standardized measures of both tests. Psychosocial positive health, health complaints, and health risk behaviors were self-reported using the items of the Health Behavior in School-aged Children questionnaire. Psychological positive health indicators included the following: perceived health status, life satisfaction, quality of family relationships, quality of peer relationships, and academic performance. We computed a health complaints index from 8 registered symptoms: headache, stomach ache, backache, feeling low, irritability or bad temper, feeling nervous, difficulties getting to sleep, and feeling dizzy. The health risk behavior indicators studied included tobacco use, alcohol use, and getting drunk. Children and adolescents with low muscular fitness (below the mean) had a higher odds ratio (OR) of reporting fair (vs. excellent) perceived health status, low life satisfaction (vs. very happy), low quality of family relationships (vs. very good), and low academic performance (vs. very good). Likewise, children and adolescents having low muscular fitness had a significantly higher OR of reporting smoking tobacco sometimes (vs. never), drinking alcohol sometimes (vs. never), and getting drunk sometimes (vs. never). The results of this study suggest a link between muscular fitness and psychological positive health and health risk behavior indicators in children and adolescents. PMID:22158258

    2014-06-01

    Between 48 million and 500 million people are thought to experience suicide bereavement every year. Over the past decade, increased policy attention has been directed towards suicide bereavement, but with little evidence to describe the effect of exposure or to provide appropriate responses. We used a systematic approach to carry out a narrative review of studies of the effect of suicide bereavement on mortality, mental health, and social functioning, and compared them with effects from other bereavements. We found 57 studies that satisfied strict inclusion criteria. Results from these studies suggested that exposure to suicide of a close contact is associated with several negative health and social outcomes, depending on an individual's relationship to the deceased. These effects included an increased risk of suicide in partners bereaved by suicide, increased risk of required admission to psychiatric care for parents bereaved by the suicide of an offspring, increased risk of suicide in mothers bereaved by an adult child's suicide, and increased risk of depression in offspring bereaved by the suicide of a parent. Some evidence was shown for increased rejection and shame in people bereaved by suicide across a range of kinship groups when data were compared with reports of relatives bereaved by other violent deaths. Policy recommendations for support services after suicide bereavement heavily rely on the voluntary sector with little input from psychiatric services to address described risks. Policymakers should consider how to strengthen health and social care resources for people who have been bereaved by suicide to prevent avoidable mortality and distress. PMID:26360405

    In the framework of the European project PASODOBLE (FP7), we set up downstream information services by combining environmental and health data with a view to support the health care community and to improve vulnerable people welfare. Indeed there is a profound relationship between human health, well-being and air pollution levels. The main objectives are to establish correlations between air quality, exposure of populations and their reactivity, to develop and validate air quality indexes and to construct a prediction model of this sanitary index. This index will be implemented on 3 European sites: Greece (Athens and Thessaloniki), the Netherlands and "Provence Alpes Côte d'Azur" (South East of France). The selected region and cities are among the most affected by the atmospheric pollution in Europe and leads to serious sanitary concerns. The service aims to provide up-to-date, detailed information on air quality discomfort. The Aggregate Risk Index is based on the Cairncross's concept, obtained from the Relative Risk associated with short-term exposure to common air pollutants and takes into account the possible effects of a mixture of pollutants. This communication tool, easy to use and intuitive, about the levels of air pollution and the associated health risks, will be used to communicate information to the general population, authorities and to the health care community and will provide advanced warning of potentially health-damaging air pollution events.

  12. Lack of data drives uncertainty in PCB health risk assessments.

    PubMed

    Cogliano, Vincent James

    2016-02-01

    Health risk assessments generally involve many extrapolations: for example, from animals to humans or from high doses to lower doses. Health risk assessments for PCBs involve all the usual uncertainties, plus additional uncertainties due to the nature of PCBs as a dynamic, complex mixture. Environmental processes alter PCB mixtures after release into the environment, so that people are exposed to mixtures that might not resemble the mixtures where there are toxicity data. This paper discusses the evolution of understanding in assessments of the cancer and noncancer effects of PCBs. It identifies where a lack of data in the past contributed to significant uncertainty and where new data subsequently altered the prevailing understanding of the toxicity of PCB mixtures, either qualitatively or quantitatively. Finally, the paper identifies some uncertainties remaining for current PCB health assessments, particularly those that result from a lack of data on exposure through nursing or on effects from inhalation of PCBs.

    This review sought to assess compliance concerns, determine risk management strategies, and identify opportunities for future research to contribute to employers' understanding of the laws and regulations that apply to on-site care. A comprehensive review of databases, professional organizations' websites, and journals resulted in 22 publications reporting on the consequences of noncompliance among on-site health centers accepted for inclusion. None of those studies reported a study design or quantifiable outcome data. Two noncompliance themes were repeated among the publications. First, direct penalties included fines, civil actions, loss of licensure, and, potentially, criminal charges. Second, noncompliance also resulted in indirect costs such as employee mistrust and lowered standards of care, which jeopardize on-site health centers' ability to demonstrate a return on investment. Further research with rigorous methodology is needed to inform employer decisions about on-site health services and associated risk management. PMID:22017191

  14. Toward a national health risk management approach in Australia.

    PubMed

    O'Donnell, Carol

    2002-01-01

    There has been increasing international consensus about the importance of competition for achieving national growth and community well-being. The Australian government accordingly has introduced policies to promote such competition. Major legislative review and many public inquiries have assisted implementation of national competition policy and the development of national goals and standards related to international agreements to promote health and sustainable development. Since the 1980s, Australia has had legislation that requires the identification and control of health risks arising at work. The management structures necessary for coordinated delivery of national programs designed for effective identification and control of health risks arising in communities to achieve national health and development goals are still being developed, however. Major difficulties related to this development are discussed. National health development programs should be approached primarily through establishment of regional partnerships between bodies responsible for managing community health, local government, and employment placement, in consultation with other relevant organizations and the community. Related research and evaluation programs are required. PMID:11905388

    Smith, Martyn T; de la Rosa, Rosemarie; Daniels, Sarah I

    2015-12-01

    Under the exposome paradigm all nongenetic factors contributing to disease are considered to be 'environmental' including chemicals, drugs, infectious agents, and psychosocial stress. We can consider these collectively as environmental stressors. Exposomics is the comprehensive analysis of exposure to all environmental stressors and should yield a more thorough understanding of chronic disease development. We can operationalize exposomics by studying all the small molecules in the body and their influence on biological pathways that lead to impaired health. Here, we describe methods by which this may be achieved and discuss the application of exposomics to cumulative risk assessment in vulnerable populations. Since the goal of cumulative risk assessment is to analyze, characterize, and quantify the combined risks to health from exposures to multiple agents or stressors, it seems that exposomics is perfectly poised to advance this important area of environmental health science. We should therefore support development of tools for exposomic analysis and begin to engage impacted communities in participatory exposome research. A first step may be to apply exposomics to vulnerable populations already studied by more conventional cumulative risk approaches. We further propose that recent migrants, low socioeconomic groups with high environmental chemical exposures, and pregnant women should be high priority populations for study by exposomics. Moreover, exposomics allows us to study interactions between chronic stress and environmental chemicals that disrupt stress response pathways (i.e., 'stressogens'). Exploring the impact of early life exposures and maternal stress may be an interesting and accessible topic for investigation by exposomics using biobanked samples. PMID:26475350

    Insufficient physical activity and excessive sedentary behavior elevate health risk. Mobile applications (apps) provide one mode for delivering interventions to modify these behaviors and reduce health risk. The purpose of this study was to characterize the need for and acceptability of health behavior interventions among rural adults and evaluate the interest in and the value of app-based interventions in this population. Central Pennsylvania adults with smartphones (N = 258) completed a brief web survey in October–November 2012. Most adults report one or both inactivity-related behavioral risk factors, would use a free app to modify those risk behaviors, and would pay a small amount for that app. Low-cost, efficacious apps to increase physical activity or reduce sedentary behavior should be promoted in public health practice. User experience should be at the forefront of this process to increase value and minimize burden in the service of long-term engagement, behavior change, and health risk reduction. PMID:26844135

    2006-01-01

    Trichloroethylene (TCE) is a common environmental contaminant at hazardous waste sites and in ambient and indoor air. Assessing the human health risks of TCE is challenging because of its inherently complex metabolism and toxicity and the widely varying perspectives on a number of critical scientific issues. Because of this complexity, the U.S. Environmental Protection Agency (EPA) drew upon scientific input and expertise from a wide range of groups and individuals in developing its 2001 draft health risk assessment of TCE. This scientific outreach, which was aimed at engaging a diversity of perspectives rather than developing consensus, culminated in 2000 with 16 state-of-the-science articles published together as an Environmental Health Perspectives supplement. Since that time, a substantial amount of new scientific research has been published that is relevant to assessing TCE health risks. Moreover, a number of difficult or controversial scientific issues remain unresolved and are the subject of a scientific consultation with the National Academy of Sciences coordinated by the White House Office of Science and Technology Policy and co-sponsored by a number of federal agencies, including the U.S. EPA. The articles included in this mini-monograph provide a scientific update on the most prominent of these issues: the pharmacokinetics of TCE and its metabolites, mode(s) of action and effects of TCE metabolites, the role of peroxisome proliferator–activated receptor in TCE toxicity, and TCE cancer epidemiology.

  19. Why is Cognitive Enhancement Deemed Unacceptable? The Role of Fairness, Deservingness, and Hollow Achievements

    PubMed Central

    Faber, Nadira S.; Savulescu, Julian; Douglas, Thomas

    2016-01-01

    We ask why pharmacological cognitive enhancement (PCE) is generally deemed morally unacceptable by lay people. Our approach to this question has two core elements. First, we employ an interdisciplinary perspective, using philosophical rationales as base for generating psychological models. Second, by testing these models we investigate how different normative judgments on PCE are related to each other. Based on an analysis of the relevant philosophical literature, we derive two psychological models that can potentially explain the judgment that PCE is unacceptable: the “Unfairness-Undeservingness Model” and the “Hollowness-Undeservingness Model.” The Unfairness-Undeservingness Model holds that people judge PCE to be unacceptable because they take it to produce unfairness and to undermine the degree to which PCE-users deserve reward. The Hollowness-Undeservingness Model assumes that people judge PCE to be unacceptable because they find achievements realized while using PCE hollow and undeserved. We empirically test both models against each other using a regression-based approach. When trying to predict judgments regarding the unacceptability of PCE using judgments regarding unfairness, hollowness, and undeservingness, we found that unfairness judgments were the only significant predictor of the perceived unacceptability of PCE, explaining about 36% of variance. As neither hollowness nor undeservingness had explanatory power above and beyond unfairness, the Unfairness-Undeservingness Model proved superior to the Hollowness-Undeservingness Model. This finding also has implications for the Unfairness-Undeservingness Model itself: either a more parsimonious single-factor “Fairness Model” should replace the Unfairness-Undeservingness-Model or fairness fully mediates the relationship between undeservingness and unacceptability. Both explanations imply that participants deemed PCE unacceptable because they judged it to be unfair. We conclude that concerns about

    Conflicting opinions on the potential hazards associated with formaldehyde exposure triggered a national workshop to address the toxicological questions concerning the health effects of formaldehyde. Since quantitative human data are not available to derive a dose-response curve for formaldehyde risk assessment, nonhuman data are used. In the case of formaldehyde, data from animals exposed to high concentrations are used to estimate human risk at much lower concentrations. This study presents the several steps that make up a risk assessment and examines any additional data that might alter significantly the risk estimates presented in the 1984 EIS. Rat inhalation chronic bioassay data from a study sponsored by the Chemical Industry Institute of Toxicology (CIIT) have been used to develop a risk equation that was subsequently used by BPA in its EIS. The CIIT data base remains the only acceptable animal data that can support the estimation of a dose-response curve. The development of mathematical models continues with a great deal of energy, and the use of different models is largely responsible for the great variability of the formaldehyde risk estimates. While one can calculate different values for carcinogenic risk associated with formaldehyde exposure than were presented earlier in the BPA EIS, they are not likely to be any better.

  1. Approaches to characterizing human health risks of exposure to fibers.

    Naturally occurring and man-made (synthetic) fibers of respirable sizes are substances that have been identified by the U.S. Environmental Protection Agency (U.S. EPA) as priority substances for risk reduction and pollution prevention under the Toxic Substances Control Act (TSCA). The health concern for respirable fibers is based on the link of occupational asbestos exposure and environmental erionite fiber exposure to the development of chronic respiratory diseases, including interstitial lung fibrosis, lung cancer, and mesothelioma in humans. There is also considerable laboratory evidence indicating that a variety of fibers of varying physical and chemical characteristics can elicit fibrogenic and carcinogenic effects in animals under certain exposure conditions. This paper discusses key scientific issues and major default assumptions and uncertainties pertaining to the risk assessment of inhaled fibers. This is followed by a description of the types of assessment performed by the U.S. EPA to support risk management actions of new fibers and existing fibers under TSCA. The scope and depth of these risk assessments, however, vary greatly depending on whether the substance under review is an existing or a new fiber, the purpose of the assessment, the availability of data, time, and resources, and the intended nature of regulatory action. In general, these risk assessments are of considerable uncertainty because health hazard and human exposure information is often incomplete for most fibers. Furthermore, how fibers cause diseases and what specific determinants are critical to fiber-induced toxicity and carcinogenicity are still not completely understood. Further research to improve our knowledge base in fiber toxicology and additional toxicity and exposure data gathering are needed to more accurately characterize the health risks of inhaled fibers.

    The aim of this study was to compare the QRISKII, an electronic health data-based risk score, to the Framingham Risk Score (FRS) and atherosclerotic cardiovascular disease (ASCVD) score. Risk estimates were calculated for a cohort of 8783 patients, and the patients were followed up from November 29, 2012, through June 1, 2015, for a cardiovascular disease (CVD) event. During follow-up, 246 men and 247 women had a CVD event. Cohen's kappa statistic for the comparison of the QRISKII and FRS was 0.22 for men and 0.23 for women, with the QRISKII classifying more patients in the higher-risk groups. The QRISKII and ASCVD were more similar with kappa statistics of 0.49 for men and 0.51 for women. The QRISKII shows increased discrimination with area under the curve (AUC) statistics of 0.65 and 0.71, respectively, compared to the FRS (0.59 and 0.66) and ASCVD (0.63 and 0.69). These results demonstrate that incorporating additional data from the electronic health record (EHR) may improve CVD risk stratification. PMID:26960568

    Abstract Health Risk Appraisals (HRAs) have been in increasingly wide use over the past 20 years as health education tools designed to encourage healthy behaviors. A major criticism of HRAs has been the error introduced by missing or incorrectly-specified responses by clients, especially regarding physiological measures such as blood pressure and cholesterol. Four HRAs were randomly assigned to members of a random sample of Massachusetts residents as part of a trial to assess the reliability and validity of HRA instruments. Two rules for substituting unknown physiological measures were evaluated: the existing rule for an HRA and a new rule, which simply substitutes the age- and gender-specific mean physiological values. Ordinary least squares regression was used to compare risk scores generated from known physiological measures, taken in respondents' homes, with risk scores generated by substitution. Regression slopes were mostly close to 1.0, most intercepts were relatively close to 0.0, and correlations were all extremely high, suggesting good performance of substitution rules on a group level. However, outliers from the regressions tended to be individuals at high risk whose risk was underestimated by the substitution rules. These results raise ethical questions about the use of substitution rules and reinforce the need for taking actual physiological measurements. PMID:22204466

    Cyanobacteria (blue-green algae) are abundant in fresh, brackish and marine waters worldwide. When toxins produced by cyanobacteria are present in the aquatic environment, seafood harvested from these waters may present a health hazard to consumers. Toxicity hazards from seafood have been internationally recognised when the source is from marine algae (dinoflagellates and diatoms), but to date few risk assessments for cyanobacterial toxins in seafood have been presented. This paper estimates risk from seafood contaminated by cyanobacterial toxins, and provides guidelines for safe human consumption. PMID:22690165

    Calcining processes including handling and storage of raw petroleum coke may result in Particulate Matter (PM) and gaseous emissions. Concerns have been raised over the potential association between particulate and aerosol pollution and adverse respiratory health effects including decrements in lung function. This risk characterization evaluated the exposure concentrations of ambient air pollutants including PM10 and gaseous pollutants from a petroleum coke calciner facility. The ambient air pollutant levels were collected through monitors installed at multiple locations in the vicinity of the facility. The measured and modeled particulate levels in ambient air from the calciner facility were compared to standards protective of public health. The results indicated that exposure levels were, on occasions at sites farther from the facility, higher than the public health limit of 150 μg/m(3) 24-h average for PM10. However, the carbon fraction demonstrated that the contribution from the calciner facility was de minimis. Exposure levels of the modeled SO2, CO, NOx and PM10 concentrations were also below public health air quality standards. These results demonstrate that emissions from calcining processes involving petroleum coke, at facilities that are well controlled, are below regulatory standards and are not expected to produce a public health risk.

    This article quantifies potential public health risks from tumor-producing pollutants emitted from two synthetic-fuel plants (direct liquefaction--Exxon Donor Solvent: and indirect liquefaction--Lurgi Fischer-Tropsch) located at a representative site in the eastern United States. In these analyses gaseous and aqueous waste streams were characterized; exposures via inhalation, terrestrial and aquatic food chains, and drinking water supplies were modeled. Analysis suggested that emissions of "polycyclic aromatic hydrocarbons," "aromatic amines," "neutral N, O, S heterocyclics," "nitriles," and "other trace elements" pose the largest quantifiable risks to public health. Data and analysis for these pollutant categories should be refined to more accurately match compound-specific estimated exposure levels with tumorigenic potency estimates. Before these results are used for regulatory purposes, more detailed analysis for selected pollutant classes are needed, and more sophisticated aquatic exposure models must be developed. Also, differences in geographic scales among the environmental transport models used need to be rectified. PMID:3843682

    The Environmental Health activity for the Extended Duration Orbiter Medical Project (EDOMP) was formed to develop an overall strategy for safeguarding crew members from potential airborne hazards anticipated on missions of extended duration. These efforts were necessary because of major modifications to the air revitalization system of the U.S. Space Shuttle and an increased potential for environmental health risks associated with longer space flights. Degradation of air quality in the Shuttle during a space flight mission has the potential to affect the performance of the crew not only during piloting, landing, or egress, but also during space flight. It was anticipated that the risk of significant deterioration in air quality would increase with extended mission lengths and could result from: (1) a major chemical contamination incident, such as a thermodegradation event or toxic leak, (2) continual accumulation of volatile organic compounds to unacceptable levels, (3) excessive levels of airborne particles, (4) excessive levels of microorganisms, or (5) accumulation of airborne pathogens.

    Identification and management the 'critical risk areas' where hotspot lead exposures are a potential risk to human health, become a major focus of public health efforts in China. But the knowledge of health risk assessment of lead pollution at regional and national scales is still limited in China. In this paper, under the guidance of 'sources-pathways-receptors' framework, regional human health risk assessment model for lead contamination was developed to calculate the population health risk in Yunnan province. And the cluster and AHP (analytic hierarchy process) analysis was taken to classify and calculate regional health risk and the decomposition of the regional health risk in the greatest health risk region, respectively. The results showed that Yunnan province can be divided into three areas. The highest health risk levels, located in northeastern Yunnan, including Kunming, Qujing, Zhaotong region. In those regions, lead is present at high levels in air, food, water and soil, and high population density which pose a high potential population risk to the public. The current study also reveals that most regional health risk was derived from the child receptors (age above 3 years) 4.3 times than the child receptors (age under 3 years), and ingestion of lead-contaminated rice was found to be the most significant contributor to the health risk (accounting for more than 49% health risk of total). This study can provide a framework for regional risk assessment in China and highlighted some indicators and uncertainties. PMID:25893826

    Chemopreventive effects of broccoli, a highly valued vegetable, have been known for a long time. Several studies have demonstrated that broccoli might be beneficial by reducing the risk for the development of certain forms of cancer. These effects are generally attributed to glucosinolate-derived degradation products like isothiocyanates and indoles which are formed by the hydrolytic action of plant myrosinase and/or glucosidases deriving from the human microbial flora. However, recent in vitro and experimental animal studies indicate that broccoli, its extracts and the glucosinolate-derived degradation products might also have undesirable effects, especially genotoxic activities. However, the relevance of the genotoxic activities to human health is not known yet. This paper gives an overview on genotoxic, anti-genotoxic/chemopreventive, nutritive and antinutritive properties of broccoli, its ingredients and their degradation products. A qualitative comparison of the benefit and risk of broccoli consumption benefit-risk assessment shows that the benefit from intake in modest quantities and in processed form outweighs potential risks. For other preparations (fortified broccoli-based dietary supplements, diets with extraordinary high daily intake, consumption as a raw vegetable) further studies both for potential risks and beneficial effects are needed in order to assess the benefit and risk in the future.

    Background: Over the past 20 years, knowledge of the genome and its function has increased dramatically, but risk assessment methodologies using such knowledge have not advanced accordingly. Objective: This commentary describes a collaborative effort among several federal and state agencies to advance the next generation of risk assessment. The objective of the NexGen program is to begin to incorporate recent progress in molecular and systems biology into risk assessment practice. The ultimate success of this program will be based on the incorporation of new practices that facilitate faster, cheaper, and/or more accurate assessments of public health risks. Methods: We are developing prototype risk assessments that compare the results of traditional, data-rich risk assessments with insights gained from new types of molecular and systems biology data. In this manner, new approaches can be validated, traditional approaches improved, and the value of different types of new scientific information better understood. Discussion and Conclusions: We anticipate that these new approaches will have a variety of applications, such as assessment of new and existing chemicals in commerce and the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances. Additionally, results of the effort are likely to spur further research and test methods development. Full implementation of new approaches is likely to take 10–20 years. PMID:22875311

    This study investigates the risk of arsenic (As) exposure to the residents in Pingtung Plain of Taiwan, where more than 50% of people extracts groundwater to meet the drinking purpose and monitoring groundwater shows that a considerable portion of groundwater has an As concentration of more than safe drinking water guideline of 10μg/L-1. Exposure and risk assessment are carried out in accordance with the provisional daily intake (PTDI) recommended by the FAO/WHO as well as hazard quotient and cancer risk standards based on the US Environmental Protection Agency. The variability of body weights and drinking water consumption scenarios are considered in exposure and risk assessment. Results shows that daily intake exceeds 2.1μg day-1 kg-1 BW for 2% of population, HQ level above unity for 20% , and can risk greater than 10-6 for 80%. These results implies that drinking water directly from groundwater will place many people at the risk of exposure and any efforts to supply safe drinking water is imperial for governing in order to protect the human health of inhabitants in Pingtung Plain.

    2013-02-01

    According to Beck's 'World at Risk' theory, global risks push nations towards a cosmopolitisation of their health policy and open opportunities for a democratic turn. This article provides an empirical analysis of Beck's theory, based on the experience of Vietnamese authorities from 2003 to 2007 in managing the emerging avian flu virus. It shows how Vietnam's framing of avian flu has shifted, under the pressure from international organisations and the US administration, from an epizootic and zoonotic risk (or a classic risk) to a pandemic threat (or a late modern risk). Vietnam's response was part of its overall strategy to join the World Trade Organization and it was limited by Vietnam's defence of its sovereignty. This strategy has been successful for Vietnam but has limited the possibility of cosmopolitan and democratic transformations. The case study highlights the constructed dimension of risks of late modernity and their possible instrumentalisation: it minimises the role of a community of fear relative to a community of trade.

    The relationship between childhood sexual abuse and subsequent health risk behaviors and medical problems was examined in 511 women who had used a family practice clinic in a rural midwestern community during a 2-year period (1988 and 1989). These women completed a questionnaire that assessed various health risk behaviors--smoking, drinking, drug abuse, number of sexual partners, and age at first intercourse--and a medical symptom checklist that assessed 38 medical problems related to major systems of body function, the somatization scale from the SCL-90, a screen for sexual abuse, and a brief measure of social support. The results indicated that sexually abused women, who represented 22.1% of the sample, reported significantly more medical problems, greater levels of somatization, and more health risk behaviors than did the nonabused women. More severe abuse (for example, penetration or multiple abusers) correlated with more severe problems. Extent of social support correlated inversely with the number of gynecologic problems reported in the sexually abused group. Fewer than 2% of the sexually abused women had discussed the abuse with a physician. To identify and assist victims of sexual abuse, physicians should become experienced with nonthreatening methods of eliciting such information when the medical history is obtained. PMID:1434879

    Background Although from a societal point of view a modal shift from car to bicycle may have beneficial health effects due to decreased air pollution emissions, decreased greenhouse gas emissions, and increased levels of physical activity, shifts in individual adverse health effects such as higher exposure to air pollution and risk of a traffic accident may prevail. Objective We describe whether the health benefits from the increased physical activity of a modal shift for urban commutes outweigh the health risks. Data sources and extraction We have summarized the literature for air pollution, traffic accidents, and physical activity using systematic reviews supplemented with recent key studies. Data synthesis We quantified the impact on all-cause mortality when 500,000 people would make a transition from car to bicycle for short trips on a daily basis in the Netherlands. We have expressed mortality impacts in life-years gained or lost, using life table calculations. For individuals who shift from car to bicycle, we estimated that beneficial effects of increased physical activity are substantially larger (3–14 months gained) than the potential mortality effect of increased inhaled air pollution doses (0.8–40 days lost) and the increase in traffic accidents (5–9 days lost). Societal benefits are even larger because of a modest reduction in air pollution and greenhouse gas emissions and traffic accidents. Conclusions On average, the estimated health benefits of cycling were substantially larger than the risks relative to car driving for individuals shifting their mode of transport. PMID:20587380

    Triggered by corporate scandals, there is increased oversight by governmental bodies and in part by the Sarbanes-Oxley Act of 2002. Corporations are developing corporate governance compliance initiatives to respond to the scrutiny of regulators, legislators, the general public and constituency groups such as investors. Due to state attorney general initiatives, new legislation and heightened oversight from the Internal Revenue Service, nonprofit entities are starting to share the media spotlight with their for-profit counterparts. These developments are changing nonprofit health care organizations as well as the traditional role of the risk manager. No longer is the risk manager focused solely on patients' welfare and safe passage through a complex delivery system. The risk manager must be aware of corporate practices within the organization that could allow the personal objectives of a few individuals to override the greater good of the community in which the nonprofit organization serves.

    2003-12-01

    High risk industries such as commercial aviation and the oil and gas industry have achieved exemplary safety performance. This paper reviews how they have managed to do that. The primary reasons are the positive attitudes towards safety and the operation of effective formal safety management systems. The safety culture provides an important explanation of why such organisations perform well. An evolutionary model of safety culture is provided in which there is a range of cultures from the pathological through the reactive to the calculative. Later, the proactive culture can evolve towards the generative organisation, an alternative description of the high reliability organisation. The current status of health care is reviewed, arguing that it has a much higher level of accidents and has a reactive culture, lagging behind both high risk industries studied in both attitude and systematic management of patient risks.

    Background: Health coaching is a client-centric process to increase motivation and self-efficacy that supports sustainable lifestyle behavior changes and active management of health conditions. This study describes an intervention offered as a benefit to health plan members and examines health and behavioral outcomes of participants. Methods: High-risk health plan enrollees were invited to participate in a telephonic health coaching intervention addressing the whole person and focusing on motivating health behavior changes. Outcomes of self-reported lifestyle behaviors, perceived health, stress levels, quality of life, readiness to make changes, and patient activation levels were reported at baseline and upon program completion. Retrospectively, these data were extracted from administrative and health coaching records of participants during the first 2 full years of the program. Results: Less than 7% of the 114 615 potential candidates self-selected to actively participate in health coaching, those with the highest chronic disease load being the most likely to participate. Of 6940 active participants, 1082 fully completed health inventories, with 570 completing Patient Activation Measure (PAM). The conditions most often represented in the active participants were depression, congestive heart failure, diabetes, hyperlipidemia, hypertension, osteoporosis, asthma, and low back pain. In 6 months or less, 89% of participants met at least one goal. Significant improvements occurred in stress levels, healthy eating, exercise levels, and physical and emotional health, as well as in readiness to make change and PAM scores. Discussion: The types of client-selected goals most often met were physical activity, eating habits, stress management, emotional health, sleep, and pain management, resulting in improved overall quality of life regardless of condition. Positive shifts in activation levels and readiness to change suggest that health coaching is an intervention deserving

    OBJECTIVE To analyze the prevalence of individuals at risk of dependence and its associated factors. METHODS The study was based on data from the Catalan Health Survey, Spain conducted in 2010 and 2011. Logistic regression models from a random sample of 3,842 individuals aged ≥ 15 years were used to classify individuals according to the state of their personal autonomy. Predictive models were proposed to identify indicators that helped distinguish dependent individuals from those at risk of dependence. Variables on health status, social support, and lifestyles were considered. RESULTS We found that 18.6% of the population presented a risk of dependence, especially after age 65. Compared with this group, individuals who reported dependence (11.0%) had difficulties performing activities of daily living and had to receive support to perform them. Habits such as smoking, excessive alcohol consumption, and being sedentary were associated with a higher probability of dependence, particularly for women. CONCLUSIONS Difficulties in carrying out activities of daily living precede the onset of dependence. Preserving personal autonomy and function without receiving support appear to be a preventive factor. Adopting an active and healthy lifestyle helps reduce the risk of dependence. PMID:26018786

    The aim of the study was to assess the health risk of workers performing specific jobs in the process of the rubber footwear production by defining the cause and length of temporary work disability, as well as mortality causes and level. The analysis was carried out in the groups of workers performing the following jobs: mixing, mill operation, pressing and vulcanizing (A); semi-product preparation and calendaring (B); finishing and sorting (C); production of polyvinyl chloride footwear (D); and auxiliary works (E). The sickness absence study covered all workers (208 men and 315 women) employed in a large rubber footwear company and performing all above-listed jobs in 1995. Standardized sick days ratio was used to analyze the risk of temporary work disability. Mortality rate was estimated on the basis of the results of the cohort study performed in the same company among workers who had worked at least three months during the years 1945-1985. The follow-up continued until 31 December 1997. The present study included sub-cohorts composed of 5628 men and 7197 women, performing jobs listed above. The results of both studies indicated the enhanced risk of cardiovascular diseases among workers employed in the basic phases of the production process. The increased risk of the diseases of the digestive system was observed in men and women employed in: finishing, sorting and packing of the products (group C); in men involved in mixing, pressing and vulcanizing (group A); and in women engaged in auxiliary works (group E). In addition, the enhanced risk of sickness absence due to the diseases of the respiratory, digestive, or genitourinary systems was related to the enhanced risk of death from malignant neoplasms in a given site. The analysis showed that the temporary work disability may be regarded as a parameter useful in early assessment of health effects of the work environmental hazards. PMID:11928670

    The migratory crisis currently faced by Europe is of exceptional magnitude since the Second World War. It is mainly related to the conflict in Syria, as well as recurring violations of human rights in other regions of the world. Widely relayed by the media, the unusual number of refugee applicants and the precariousness of their migration routes raise the question of the health risk. From the old concept of quarantine to the new paradigm of migrants' health, it is important to contextualize the screening measures, taking into account the epidemiology of communicable diseases in the countries of origin and of the regions crossed, the ruptures of access to treatments for chronic diseases, but also the impact of multiple trauma (war, violence) on the mental health of refugees.

    2015-01-01

    Consumers and patients want to be included in decisions regarding their own health and have an ethically justified claim on informed decisions. Therefore, sound information is required, but health information is often misleading and based on different interests. The risks of disease and the benefits of medical interventions tend to be overestimated, whereas harm is often underestimated. Evidence-based health information has to fulfil certain criteria, for instance, it should be evidence-based, independent, complete, true as well as understandable. The aim of a medical intervention has to be explained. The different therapeutic options including the option not to intervene have to be delineated. The probabilities for success, lack of success and unwanted side effects have to be communicated in a numerical and understandable manner. Patients have the right to reject medical interventions without any sanctions. PMID:26195924

    The combination of standard quantitative microbial risk analysis (QMRA) techniques and 10,000-trial Monte Carlo risk simulations was used to estimate the human health risks associated with the use of wastewater for unrestricted and restricted crop irrigation. A risk of rotavirus infection of 10(-2) per person per year (pppy) was used as the reference level of acceptable risk. Using the model scenario of involuntary soil ingestion for restricted irrigation, the risk of rotavirus infection is approximately 10(-2) pppy when the wastewater contains < or =10(6) Escherichia coli per 100ml and when local agricultural practices are highly mechanised. For labour-intensive agriculture the risk of rotavirus infection is approximately 10(-2) pppy when the wastewater contains < or = 10(5) E. coli per 100ml; however, the wastewater quality should be < or = 10(4) E. coli per 100ml when children under 15 are exposed. With the model scenario of lettuce consumption for unrestricted irrigation, the use of wastewaters containing < or =10(4) E. coli per 100ml results in a rotavirus infection risk of approximately 10(-2) pppy; however, again based on epidemiological evidence from Mexico, the current WHO guideline level of < or =1,000 E. coli per 100ml should be retained for root crops eaten raw.

    To document the problem of child labor as a health issue, we report here three case-studies in Ecuador: exposure to mercury among gold washers, exposure to organophosphates and carbamates in the fruit-growing industry, and exposure to solvents among shoe cleaners. We measured the relevant biological indicators of exposure (mercury in urine, urinary levels of phenols, and acetylcholine esterase in erythrocytes) among selected samples of 10 children for each working place. In all the case studies, the values of the biological indicators showed elevated exposure to well-known toxicants, which are now rare in developed countries, even among adult workers. The findings meld with a previously reported case study of intoxication from inorganic lead among children employed in the manufacture of roof tiles in Ecuador. This study highlights the need to properly evaluate and control the potential health effects due to exposure to toxic substances among children employed in different occupations in several parts of the world.

    Health maintenance (HM) practices are essential to prevent illness, promote well-being, and maximize health. Patients with multiple myeloma (MM) are at increased risk for cardiovascular disease and cancers, yet, research on HM practices and preventative care of MM survivors has limited report. The study comprised a descriptive, correlational, and cross-sectional online survey design. Survey of patients with MM was carried out through the International Myeloma Foundation (IMF) and the Association of Cancer Online Resources (ACOR) e-mail list services. The members of the IMF and ACOR e-mail list services were surveyed, of which 237 patients responded. The modified Medical Expenditure Preventive Survey-Preventive Care questionnaire was used; it included items that ask patients regarding their healthcare practices that relate to dental care, cancer prevention, addiction, lifestyles, sensory screening, immunizations, cardiovascular, endocrine, psychosocial, and bone health. Descriptive statistics, Pearson's chi-square, and Spearman's rho correlation coefficient were obtained. In this study, men had statistically significant inferior global health maintenance scores than women (P = 0.002). Being employed (P = 0.054) and married or partnered (P = 0.017) were significantly correlated with better health maintenance patterns among male respondents. In contrast, no statistically significant correlations between sociodemographic factors and health maintenance patterns were found in women. Patients with MM, particularly men, require continued education and close monitoring of health maintenance practices. These findings are consistent with publications looking at gender disparities in healthcare utilization in the United States. Studies show that men, in general, are less likely to seek preventative healthcare screenings. Healthcare providers must incorporate health maintenance promotion during clinic visits. PMID:27119422

  10. Incidence of Online Health Information Search: A Useful Proxy for Public Health Risk Perception

    2013-01-01

    Background Internet users use search engines to look for information online, including health information. Researchers in medical informatics have found a high correlation of the occurrence of certain search queries and the incidence of certain diseases. Consumers’ search for information about diseases is related to current health status with regard to a disease and to the social environments that shape the public’s attitudes and behaviors. Objective This study aimed to investigate the extent to which public health risk perception as demonstrated by online information searches related to a health risk can be explained by the incidence of the health risk and social components of a specific population’s environment. Using an ecological perspective, we suggest that a population’s general concern for a health risk is formed by the incidence of the risk and social (eg, media attention) factors related with the risk. Methods We constructed a dataset that included state-level data from 32 states on the incidence of the flu; a number of social factors, such as media attention to the flu; private resources, such as education and health insurance coverage; public resources, such as hospital beds and primary physicians; and utilization of these resources, including inpatient days and outpatient visits. We then explored whether online information searches about the flu (seasonal and pandemic flu) can be predicted using these variables. We used factor analysis to construct indexes for sets of social factors (private resources, public resources). We then applied panel data multiple regression analysis to exploit both time-series and cross-sectional variation in the data over a 7-year period. Results Overall, the results provide evidence that the main effects of independent variables—the incidence of the flu (P<.001); social factors, including media attention (P<.001); private resources, including life quality (P<.001) and health lifestyles (P=.009); and public

    The U.S. Environmental Protection Agency (EPA) is preparing, for the U.S. Congress, a report evaluating the need to regulate mercury (Hg) emissions from electric utilities. This study, to be completed in 1995, will have important health and economic implications. In support of these efforts, the U.S. Department of Energy, Office of Fossil Energy, sponsored a risk assessment project at Brookhaven National Laboratory (BNL) to evaluate methylmercury (MeHg) hazards independently. In the BNL study, health risks to adults resulting from Hg emissions from a hypothetical 1000 MW{sub e} coal-fired power plant were estimated using probabilistic risk assessment techniques. The approach draws on the extant knowledge in each of the important steps in the calculation chain from emissions to health effects. Estimated results at key points in the chain were compared with actual measurements to help validate the modeled estimates. Two cases were considered: the baseline case (no local impacts), and the impact case (maximum local power-plant impact). The BNL study showed that the effects of emissions of a single power plant may double the background exposures to MeHg resulting from consuming fish obtained from a localized area near the power plant. Many implicit and explicit sources of uncertainty exist in this analysis. Those that appear to be most in need of improvement include data on doses and responses for potentially sensitive subpopulations (e.g., fetal exposures). Rather than considering hypothetical situations, it would also be preferable to assess the risks associated with actual coal-fired power plants and the nearby sensitive water bodies and susceptible subpopulations. Finally, annual total Hg emissions from coal burning and from other anthropogenic sources are still uncertain; this makes it difficult to estimate the effects of U.S. coal burning on global Hg concentration levels, especially over the long term.

    2010-01-01

    Background Using the most effective methods and techniques for communicating risk to the public is critical. Understanding the impact that different types of risk communication have played in real and perceived public health risks can provide information about how messages, policies and programs can and should be communicated in order to be most effective. The purpose of this systematic review is to identify the effectiveness of communication strategies and factors that impact communication uptake related to environmental health risks. Methods A systematic review of English articles using multiple databases with appropriate search terms. Data sources also included grey literature. Key organization websites and key journals were hand searched for relevant articles. Consultation with experts took place to locate any additional references. Articles had to meet relevance criteria for study design [randomized controlled trials, clinical controlled trials, cohort analytic, cohort, any pre-post, interrupted time series, mixed methods or any qualitative studies), participants (those in community-living, non-clinical populations), interventions (including, but not limited to, any community-based methods or tools such as Internet, telephone, media-based interventions or any combination thereof), and outcomes (reported measurable outcomes such as awareness, knowledge or attitudinal or behavioural change). Articles were assessed for quality and data was extracted using standardized tools by two independent reviewers. Articles were given an overall assessment of strong, moderate or weak quality. Results There were no strong or moderate studies. Meta-analysis was not appropriate to the data. Data for 24 articles were analyzed and reported in a narrative format. The findings suggest that a multi-media approach is more effective than any single media approach. Similarly, printed material that offers a combination of information types (i.e., text and diagrams) is a more effective

    This research has aimed to identify the perceptions of women apprentice welders about physical, chemical, biological, and physiological risk factors to which they are exposed and evaluate the identification of health disorders self-reported for women apprentice welders before and after implementation of a nursing socioenvironmental intervention. A quantitative study was performed with 27 women apprentice welders (first phase) and before and after an intervention with 18 women (second phase) in Southern Brazil in 2011. The data were analysed using SPSS 19.0. The participants identified the following risk types: physical (96.2%), chemical (96.2%), physiological (88.8%), and biological (62.9%). The results show a significant difference of the pre- and posttest averages for the musculoskeletal system and a posttest average increase for the integumentary, respiratory, and auditory system. A correlation of the women apprentices' ages and the identification of health disorders were made. It was understood that the perception of women apprentices regarding a particular set of occupational risks is essential for public health nursing to develop an effective risk communication as a positive tool for teaching and learning.

    Like many elements, fluorine (which generally occurs in nature as fluoride) is beneficial to human health in trace amounts, but can be toxic in excess. The links between low intakes of fluoride and dental protection are well known; however, fluoride is a powerful calcium-seeking element and can interfere with the calcified structure of bones and teeth in the human body at higher concentrations causing dental or skeletal fluorosis. One of the main exposure routes is via drinking water and the World Health Organisation currently sets water quality guidelines for the element. In Central Europe, groundwater resources that exceed the guideline value of 1.5 mg l-1 are widespread and effects on health of high fluoride in water have been reported. The aim of the current project was to develop a geographic information system (GIS) to aid the identification of areas where high-fluoride waters and fluorosis may be a problem; hence, where water treatment technologies should be targeted. The development of the GIS was based upon the collation and digitisation of existing information relevant to fluoride risk in Ukraine, Moldova, Hungary and Slovakia assembled for the first time in a readily accessible form. In addition, geochemistry and health studies to examine in more detail the relationships between high-fluoride drinking waters and health effects in the population were carried out in Moldova and Ukraine demonstrating dental fluorosis prevalence rates of 60-90% in adolescents consuming water containing 2-7 mg l-1 fluoride.

    Whether the result of cyclical atmospheric changes, anthropogenic activities, or combinations of both, authorities now agree that the earth is warming from a variety of climatic effects, including the cascading effects of greenhouse gas emissions to support human activities. To date, most reports of the public health outcomes of global warming have been anecdotal and retrospective in design and have focused on heat stroke deaths following heat waves, drowning deaths in floods and tsunamis, and mosquito-borne infectious disease outbreaks following tropical storms and cyclones. Accurate predictions of the true public health outcomes of global climate change are confounded by several effect modifiers including human acclimatization and adaptation, the contributions of natural climatic changes, and many conflicting atmospheric models of climate change. Nevertheless, temporal relationships between environmental factors and human health outcomes have been identified and may be used as criteria to judge the causality of associations between the human health outcomes of climate changes and climate-driven natural disasters. Travel medicine physicians are obligated to educate their patients about the known public health outcomes of climate changes, about the disease and injury risk factors their patients may face from climate-spawned natural disasters, and about the best preventive measures to reduce infectious diseases and injuries following natural disasters throughout the world.

    Purpose Sudden cardiac death (SCD) is an important cause of mortality in the adult population. Height has been associated with cardiac hypertrophy and an increased risk of arrhythmias, but also with decreased risk of coronary heart disease, suggesting a complex association with SCD. Methods We examined the association of adult height with the risk of physician-adjudicated SCD in two large population-based cohorts: the Cardiovascular Health Study (CHS) and the Atherosclerosis Risk in Communities (ARIC) study. Results Over an average follow-up time of 11.7 years in CHS, there were 199 (3.6%) cases of SCD among 5,556 participants. In ARIC, over 12.6 years, there were 227 (1.5%) cases of SCD among 15,633 participants. In both cohorts, there was a trend towards decreased SCD with taller height. In fixed effects meta-analysis, the pooled hazard ratio per 10 cm of height was 0.84 (95%CI 0.73, 0.98, p=0.03). The association of increased height with lower risk of SCD was slightly attenuated after inclusion of risk factors associated with height, such as hypertension and left ventricular hypertrophy. The association appeared stronger among men than women in both cohorts. Conclusion In two population-based prospective cohorts of different ages, greater height was associated with lower risk of SCD.

    Abstract Homosexual adolescents may face significant health disparities. We examined health-risk behaviors and health cognition related to homosexual behavior in a representative sample of adolescents. Data were obtained from 129,900 adolescents between 2008 and 2012 over 5 cycles of the Korean Youth Risk Behavior Survey, a national survey of students in grades 7 to 12. Various health-risk behaviors and aspects of health cognition were compared between homosexual and heterosexual adolescents and analyzed with multiple logistic regression models. Compared with heterosexual adolescents (n = 127,594), homosexual adolescents (n = 2306) were more likely to engage in various health-risk behaviors and to have poor health cognition. In multiple logistic regression analysis, not living with parents, alcohol experience (adjusted odds ratio, 1.50; 95% confidence interval, 1.26–1.78 for males and 1.66; 1.33–2.07 for females), smoking experience (1.80; 1.54–2.10 for males and 3.15; 2.61–3.79 for females), and drug experience (3.65; 2.81–4.80 for males and 3.23; 2.35–4.46 for females) were associated with homosexual behavior. Homosexual adolescents were more likely to use adult internet content (2.82; 2.27–3.50 for males and 7.42; 4.19–13.15 for females), and to be depressed (1.21; 1.03–1.43 for males and 1.32; 1.06–1.64 for females). In addition, suicide ideation (1.51; 1.26–1.81 for males and 1.47; 1.16–1.86 for females) and attempts (1.67; 1.37–2.05 for males and 1.65; 1.34–2.03 for females) were significantly more prevalent among homosexual adolescents. Homosexual adolescents report disparities in various aspects of health-risk behavior and health cognition, including use of multiple substances, adult internet content and inappropriate weight loss methods, suicide ideation and attempts, and depressive mood. These factors should be addressed relevantly to develop specific interventions regarding sexual minorities. PMID:27227939

    In most industrialized countries large numbers of workers are exposed to welding fumes. Although the general pattern of welders' health may not significantly differ from that of workers in other dusty industrial occupations which demonstrate elevated incidence of respiratory tract diseases with long latency periods, the extremely wide range of substances at potentially high concentrations produced by various welding technologies may give rise to undetected process-specific high-risk working conditions: ("hot spots"). The origin, prevalence and range of magnitude of such hot spots, especially for cancer of the respiratory tract, is discussed, with emphasis placed on the assessment of risk resulting from exposure to Cr(VI) and Ni accompanying the use of various technologies for the welding of stainless and high alloy steels. The wide variation of health effects found within the industry, however, indicates the need for a standard protocol for future epidemiological studies, as well as for the development of suitable methodologies for experimental risk assessment.

    High arsenic exposures, prevalent through dietary and non-dietary sources in Bangladesh, present a major health risk to the public. A quantitative human health risk assessment is described as a result of arsenic exposure through food and water intake, tea intake, accidental soil ingestion, and chewing of betel quid, while people meet their desirable dietary intake requirements throughout their lifetime. In evaluating the contribution of each intake pathway to average daily arsenic intake, the results show that food and water intake combined, makes up approximately 98% of the daily arsenic intake with the balance contributed to by intake pathways such as tea consumption, soil ingestion, and quid consumption. Under an exposure scenario where arsenic concentration in water is at the WHO guideline (0.01 mg/L), food intake is the major arsenic intake pathway ranging from 67% to 80% of the average daily arsenic intake. However, the contribution from food drops to a range of 29% to 45% for an exposure scenario where arsenic in water is at the Bangladesh standard (0.05 mg/L). The lifetime excess risk of cancer occurrence from chronic arsenic exposure, considering a population of 160 million people, based on an exposure scenario with 85 million people at the WHO guideline value and 75 million people at the Bangladesh standard, and assuming that 35 million people are associated with a heavy activity level, is estimated as 1.15 million cases.

    Over the past decade, health risk assessment (HRA) has become the preferred decision-making tool for judging whether a site (ex., hazardous waste site) or an activity (ex., facility operation) may be safe or unsafe. Currently, no consensus HRA methodology has evolved for evaluating complex mixtures such as petroleum hydrocarbons, either for assessing baseline health risk or for setting environmental corrective action goals. The most common HRA approach is to evaluate individual compounds, not complex mixtures. Because no consensus approach has been forthcoming, regulatory agencies have adopted widely varying requirements related to environmental remediation programs for petroleum hydrocarbons, particularly total petroleum hydrocarbons (TPH). Corrective action goals for TPH are known to range in degree of conservatism from a concentration equivalent to the practical limit of quantification (PLQ) to ignoring the TPH component altogether. The primary objectives of this paper are two-fold; (1) to review the various methods employed for setting TPH corrective action goals, and (2) to evaluate HRA methodologies applicable to residual TPH in environmental media. This paper will also discuss and evaluate an HRA methodology, herein referred to as a fractionation approach, which the authors believe to be the most scientific and logical approach for assessing risk for petroleum hydrocarbons in environmental media. Rationale for this HRA methodology as opposed to other approaches are discussed.

    Roma people in B&H are a marginalised population group. Their health condition; is considerably worse than the condition of other population groups. The health problems of Roma people correlate with inadequate living and dwelling conditions. Roma children are facing the impossibility of being health care beneficiaries, because their parents are unemployed. The objective of this survey was to examine the family surrounding of children in age up to 8 years, including the social conditions under which they live and the presence of health risk behaviour. The research presents a descriptive cross-section study. We interviewed 1100 non-Roma parents and children and 383 Roma parents and children (in the communities of domicile Roma people) in B&H Federation. The results obtained indicate that only 17,8 % of Roma parents are secondary-school leavers, while remaining percentage covers those with incomplete primary school or without education at all, against 63,6% of non-Roma parents who have secondary education. The parents consider themselves good providers for their children (59,3% of Roma parents and 75% of non-Roma parents often play with their children). The Roma parents seek for medical attention for their children only in the cases when urgent health problems occur, such as fever/increased body temperature (one-half of the interviewed parents) or diarrhoea (31,9%). Physical punishment of children occurs more frequently in Roma families (23,7% - this is only the top of an iceberg) then in non-Roma families (11,4%). The parents usually beat children by using their hands or punish them by flogging. The domestic violence is accepted amongst Roma people and it has most sever impact on children, who suffer emotionally and physically. In the future, it will be necessary to create the kind of family environment that would enable improvement of health condition and decrease the behaviour that endangers the health of children.

    Floods can pose a number of safety and health hazards for flood-affected populations and rescuers and bring risk of injuries, infections, and diseases due to exposure to pathogenic microorganisms and different biological and chemical contaminants. The risk factors and possible health consequences for the rescuers involved in evacuation and rescuing operations during the May 2014 flood crisis in Croatia are shown, as well as measures for the prevention of injuries and illnesses. In cases of extreme floods, divers play a particularly important role in rescuing and first-response activities. Rescuing in contaminated floodwaters means that the used equipment such as diving suits should be disinfected afterwards. The need for securing the implementation of minimal health and safety measures for involved rescuers is paramount. Data regarding injuries and disease occurrences among rescuers are relatively scarce, indicating the need for medical surveillance systems that would monitor and record all injuries and disease occurrences among rescuers in order to ensure sound epidemiological data. The harmful effects of flooding can be reduced by legislation, improvement of flood forecasting, establishing early warning systems, and appropriate planning and education. PMID:25741935

    Tobacco is one of the cadmium accumulation and tolerance plants. Decreasing cadmium content of tobacco contributes to environmental safety and human health. Three aspects on tobacco cadmium research were reviewed in this paper, i.e. uptake and distribution of cadmium in tobacco, and health risk assessment of cadmium in tobacco and reduction measures. The current situations and existing challenges in the research field were discussed. The cadmium tolerance mechanisms of tobacco were reviewed, the factors on cadmium uptake were analyzed, and the general distribution of cadmium in tobacco was summarized. From the point of health risk assessment, the lack of cadmium limits in tobacco was identified, the recommended formula to calculate cadmium limits of tobacco based on atmosphere cadmium limits and digestion cadmium limits was provided and the cadmium limits of tobacco were estimated using each formula, and suggestions on cadmium limits in tobacco were presented. At last, we put forward several effective reduction measures to lower cadmium level in tobacco leaves. PMID:26259474

    There is a cascade of risks associated with a hazard evolving into a disaster that consists of the risk that: (1) a hazard will produce an event; (2) an event will cause structural damage; (3) structural damage will create functional damages and needs; (4) needs will create an emergency (require use of the local response capacity); and (5) the needs will overwhelm the local response capacity and result in a disaster (ie, the need for outside assistance). Each step along the continuum/cascade can be characterized by its probability of occurrence and the probability of possible consequences of its occurrence, and each risk is dependent upon the preceding occurrence in the progression from a hazard to a disaster. Risk-reduction measures are interventions (actions) that can be implemented to: (1) decrease the risk that a hazard will manifest as an event; (2) decrease the amounts of structural and functional damages that will result from the event; and/or (3) increase the ability to cope with the damage and respond to the needs that result from an event. Capacity building increases the level of resilience by augmenting the absorbing and/or buffering and/or response capacities of a community-at-risk.

    This study aims to establish the prevalence of risky health behaviors among Thai youth and to characterize the prevalence of these behaviors by gender, age group, educational status, and region. We analyzed data from a population-based, nationally representative, cross-sectional survey of 938 youth aged between 13 and 24 years, sampled from Bangkok and 4 regions of Thailand. The 2011 Youth Risk Behavior Surveillance System questionnaire was used to measure youth risk behaviors. This study finds that 15.9% of respondents had engaged in physical fights, and 8.1% had been cyber bullied. The prevalence of current cigarette smoking, alcohol, and marijuana use were 22.3%, 27.9%, and 2.3%, respectively. The prevalence of risky behaviors among Thai youth were found to be high, including behaviors that contribute to unintentional injuries and violence, unsafe sexual behaviors, and cigarette and alcohol consumption.

    The risk assessment of genetically modified (GM) crops for human nutrition and health has not been systematic. Evaluations for each GM crop or trait have been conducted using different feeding periods, animal models, and parameters. The most common result is that GM and conventional sources induce similar nutritional performance and growth in animals. However, adverse microscopic and molecular effects of some GM foods in different organs or tissues have been reported. Diversity among the methods and results of the risk assessments reflects the complexity of the subject. While there are currently no standardized methods to evaluate the safety of GM foods, attempts towards harmonization are on the way. More scientific effort is necessary in order to build confidence in the evaluation and acceptance of GM foods. PMID:19146501

    OBJECTIVES. This study undertook to examine relationships between nonsedentary activity level, time spent watching television (TV)/videocassette recorder (VCR), and risk of overweight among men. METHODS. Men participating in the Health Professionals Follow-Up Study were mailed surveys. Cross-sectional analyses examined the prevalence and odds of being overweight, prospective analyses determined cumulative incidence rates and relative risks of becoming overweight over 2 years of follow-up. RESULTS. Cross-sectionally, odds of being overweight were 50% (95% confidence interval [CI] = 45%; 55%) lower for men in the highest quintile of nonsedentary activity level when compared with men in the lowest quintile. Among men watching 41 or more hours of TV/VCR per week, the odds of being overweight were 406 (95% CI = 2.67, 6.17) times greater than those for men watching no more than 1 hour per week. Prospectively, higher levels is of nonsedentary activity and lower levels of TV/VCR viewing were independently associated with lower relative risks for becoming overweight between survey years. CONCLUSIONS. Both a lack of nonsedentary activity and time spent watching TV/VCR contribute to the development of overweight in men. Sedentary and nonsedentary activities represent separate domains, each with independent risks for overweight. PMID:8561237

    Following more than a decade of scientific debate about the setting of a standard for 222Rn in drinking water, Congress established a timetable for the promulgation of a standard in the 1996 Amendments to the Safe Drinking Water Act. As a result of those Amendments, the EPA contracted with the National Academy of Sciences to undertake a risk assessment for exposure to radon in drinking water. In addition, the resulting committee was asked to address several other scientific issues including the national average ambient 222Rn concentration and the increment of 222Rn to the indoor- air concentration arising from the use of drinking water in a home. A new dosimetric analysis of the cancer risk to the stomach from ingestion was performed. The recently reported risk estimates developed by the BEIR VI Committee for inhalation of radon decay products were adopted. Because the 1996 Amendments permit states to develop programs in which mitigation of air- producing health-risk reductions equivalent to that which would be achieved by treating the drinking water, the scientific issues involved in such 'multimedia mitigation programs' were explored.

    Public health agencies increasingly use electronic means to acquire, use, maintain, and store personal health information. Electronic data formats can improve performance of core public health functions, but potentially threaten privacy because they can be easily duplicated and transmitted to unauthorized people. Although such security breaches do occur, electronic data can be better secured than paper records, because authentication, authorization, auditing, and accountability can be facilitated. Public health professionals should collaborate with law and information technology colleagues to assess possible threats, implement updated policies, train staff, and develop preventive engineering measures to protect information. Tightened physical and electronic controls can prevent misuse of data, minimize the risk of security breaches, and help maintain the reputation and integrity of public health agencies. PMID:18382010

    This study evaluates the health risks in megacities in terms of mortality and morbidity due to air pollution. A new spreadsheet model, Risk of Mortality/Morbidity due to Air Pollution (Ri-MAP), is used to estimate the excess numbers of deaths and illnesses. By adopting the World Health Organization (WHO) guideline concentrations for the air pollutants SO 2, NO 2 and total suspended particles (TSP), concentration-response relationships and a population attributable-risk proportion concept are employed. Results suggest that some megacities like Los Angeles, New York, Osaka Kobe, Sao Paulo and Tokyo have very low excess cases in total mortality from these pollutants. In contrast, the approximate numbers of cases is highest in Karachi (15,000/yr) characterized by a very high concentration of total TSP (˜670 μg m -3). Dhaka (7000/yr), Beijing (5500/yr), Karachi (5200/yr), Cairo (5000/yr) and Delhi (3500/yr) rank highest with cardiovascular mortality. The morbidity (hospital admissions) due to Chronic Obstructive Pulmonary Disease (COPD) follows the tendency of cardiovascular mortality. Dhaka and Karachi lead the rankings, having about 2100/yr excess cases, while Osaka-Kobe (˜20/yr) and Sao Paulo (˜50/yr) are at the low end of all megacities considered. Since air pollution is increasing in many megacities, and our database of measured pollutants is limited to the period up to 2000 and does not include all relevant components (e.g. O 3), these numbers should be interpreted as lower limits. South Asian megacities most urgently need improvement of air quality to prevent excess mortality and morbidity due to exceptionally high levels of air pollution. The risk estimates obtained from Ri-MAP present a realistic baseline evaluation for the consequences of ambient air pollution in comparison to simple air quality indices, and can be expanded and improved in parallel with the development of air pollution monitoring networks.

  17. Health-risk assessment of incinerator stack emissions: Trace metals

    1990-01-01

    The research presented in this dissertation centers on the development of a method for health risk assessment of incinerator stack emissions within the context of multiple exposure pathways and on its application to a problem of contemporary interest. The emphasis is on toxic metal emissions from municipal solid waste (MSW) incinerators. A comparison of the amount of metal emissions shows that toxic metal emissions from MSW incinerators are generally of the same order of magnitude as those from hazardous waste incinerators. A hazard index for stack emitted metals based on toxicity and quantity are developed in this dissertation to screen metals which are important from a risk view-point. From this hazard index, lead and mercury are added to the known carcinogenic metals, i.e., arsenic, beryllium, cadmium, chromium, and nickel as candidates for the assessment. The method presented in this dissertation consists of hazard identification and hazard quantification. If a substance is identified as a potential human carcinogen, the carcinogenicity may be related to the chemical form of a substance and the route of exposure. Regarding the carcinogenic potency of a pollutant, the chemical form of a substance and the route of exposure is investigated. This type of information with regard to carcinogenic uncertainty is incorporated into hazard quantification. The appropriate carcinogenic group of a pollutant is also identified. In order to quantify the human health risks for the 7 metals, the following are determined in this dissertation: emission factors; mass particle-size distributions; air dispersion models; exposure assessment models; population data; and unit risks or cancer potency factors.

    Lawrence Livermore National Laboratory (LLNL) is a USDOE research and development institution for science and technology applied to national security. The specific area that is the subject of this document, Area 514, was the location of active LLNL waste treatment facilities until November 2003, and the operations there were authorized under interim status. The site is being closed pursuant to the requirements of the Resource Conservation Recovery Act. The DTSC-approved ''Closure Plan for Area 514 Treatment and Storage Facility, LLNL 2004'', states clean closure concentrations for certain organic compounds, metals and metalloids. if all soil samples contained measured concentrations less than these levels, it was agreed that the site would meet the requirements for clean closure. However, if the samples had measured concentrations greater than the clean closure levels, a more detailed risk assessment could be prepared to evaluate the potential effects of the actual measured levels. Soil samples collected from 33 locations in Area 514 were analyzed for 37 constituents of potential concern, as identified by the Closure Plan. Many of these compounds and elements were not detected. However, 10 metals or metalloids were present at levels above the clean closure requirements, and 19 organic compounds were identified as contaminants of potential concern. Following the guidance in the Closure Plan, a health risk assessment is presented in this document to demonstrate the low level of potential health effects from the remaining constituents and to support clean closure of the site. Three types of hypothetical receptors were identified: an intrusive construction worker conducting trenching in the area, a bystander worker in a nearby building, and a future resident. Of the worker receptors, the intrusive construction worker was found to have the greater overall chronic exposure, with a theoretical calculated carcinogenic risk of 4 x 10{sup -8}, a chronic hazard index of 8 x

    Acidic deposition, commonly referred to as acid rain, is causing serious environmental damage in eastern Canada. The revenues from forest products, tourism and sport fishing are estimated to account for about 8% of the gross national product. The impact on human health is not as clearcut and a multi-department program on the Long-Range Transport of Airborne Pollutants (LRTAP) was approved by the federal government in June 1980. The objectives of the LRTAP program are to reduce wet sulfate deposition to less than 20 kg/ha per year in order to protect moderately sensitive areas. This will require a 50% reduction in Canadian SO2 emissions east of the Saskatchewan/Manitoba border and concomitant reductions in the eastern U.S.A. The objectives of the health sector of the program are to assess the risk to health posed by airborne pollutants which are subjected to long-range transport and to monitor the influence of abatement programs. Two major epidemiology studies were undertaken in 1983, one in which the health effects related to acute exposure to transported air pollutants were studied in asthmatic and nonasthmatic children, and another in which the effects of chronic exposure to these pollutants were studied in school children living in towns with high and low levels of pollutants. Preliminary analysis of the data do not indicate major health effects, but definitive conclusions must await final analysis. Studies on the indirect effects of acid deposition on water quality have shown that acidified lake water left standing in the plumbing system can adversely affect water quality and that federally set guidelines for copper and lead are exceeded. Flushing of the system before using the water rectifies the situation. Additional studies are planned to further delineate the magnitude of the health effects of acidified lake water. PMID:4076081

    The risks of genetically modified organisms (GMOs) are evaluated traditionally by combining hazard identification and exposure estimates to provide decision support for regulatory agencies. We question the utility of the classical risk paradigm and discuss its evolution in GMO risk assessment. First, we consider the problem of uncertainty, by comparing risk assessment for environmental toxins in the public health domain with genetically modified organisms in the environment; we use the specific comparison of an insecticide to a transgenic, insecticidal food crop. Next, we examine normal accident theory (NAT) as a heuristic to consider runaway effects of GMOs, such as negative community level consequences of gene flow from transgenic, insecticidal crops. These examples illustrate how risk assessments are made more complex and contentious by both their inherent uncertainty and the inevitability of failure beyond expectation in complex systems. We emphasize the value of conducting decision-support research, embracing uncertainty, increasing transparency, and building interdisciplinary institutions that can address the complex interactions between ecosystems and society. In particular, we argue against black boxing risk analysis, and for a program to educate policy makers about uncertainty and complexity, so that eventually, decision making is not the burden that falls upon scientists but is assumed by the public at large.

    The first case of chronic beryllium disease (CBD) at the Rocky Flats Environmental Technology Site (Rocky Flats) was diagnosed in a machinist in 1984. Rocky Flats, located 16 miles northwest of Denver, Colorado, is part of the United States Department of Energy (DOE) nuclear weapons complex. Research and development operations using beryllium began at Rocky Flats in 1953, and beryllium production operations began in 1957. Exposures could have occurred during foundry operations, casting, shearing, rolling, cutting, welding, machining, sanding, polishing, assembly, and chemical analysis operations. The Beryllium Health Surveillance Program (BHSP) was established in June 1991 at Rocky Flats to provide health surveillance for beryllium exposed employees using the Lymphocyte Proliferation Test (LPT) to identify sensitized individuals. Of the 29 cases of CBD and 76 cases of beryllium sensitization identified since 1991, several cases appear to have had only minimal opportunistic exposures to beryllium, since they were employed in administrative functions rather than primary beryllium operations. In conjunction with other health surveillance programs, a questionnaire and interview are administered to obtain detailed work and health histories. These histories, along with other data, are utilized to estimate the extent of an individual's exposure. Additional surveillance is in progress to attempt to characterize the possible risks from intermittent or brief exposures to beryllium in the workplace. PMID:8711738

    Human health depends on reliable access to safe drinking water, but in many developing countries only a limited number of wells and boreholes are available. Many of these water resources are contaminated with biological or chemical pollutants. The goal of this study was to examine water access and quality in urban Bo, Sierra Leone. A health census and community mapping project in one neighborhood in Bo identified the 36 water sources used by the community. A water sample was taken from each water source and tested for a variety of microbiological and physicochemical substances. Only 38.9% of the water sources met World Health Organization (WHO) microbial safety requirements based on fecal coliform levels. Physiochemical analysis indicated that the majority (91.7%) of the water sources met the requirements set by the WHO. In combination, 25% of these water resources met safe drinking water criteria. No variables associated with wells were statistically significant predictors of contamination. This study indicated that fecal contamination is the greatest health risk associated with drinking water. There is a need to raise hygiene awareness and implement inexpensive methods to reduce fecal contamination and improve drinking water safety in Bo, Sierra Leone. PMID:22350346

    The threat of climate change and global warming is now recognised worldwide and some alarming manifestations of change have occurred. The Asian continent, because of its size and diversity, may be affected significantly by the consequences of climate change, and its new status as a 'hub' of livestock production gives it an important role in mitigating possible impacts of climate variability on animal health. Animal health may be affected by climate change in four ways: heat-related diseases and stress, extreme weather events, adaptation of animal production systems to new environments, and emergence or re-emergence of infectious diseases, especially vector-borne diseases critically dependent on environmental and climatic conditions. To face these new menaces, the need for strong and efficient Veterinary Services is irrefutable, combined with good coordination of public health services, as many emerging human diseases are zoonoses. Asian developing countries have acute weaknesses in their Veterinary Services, which jeopardises the global surveillance network essential for early detection of hazards. Indeed, international cooperation within and outside Asia is vital to mitigating the risks of climate change to animal health in Asia. PMID:18819679

    A health risk assessment method of pollutants from fixed sources was developed by applying AERMOD model in the health risk assessment. The method could directly forecast the health risks of toxic pollutants from source by some exposure pathway. Using the established method, in combination with the data of sources and traditional health risk assessment method as well as the measured data of PAHs in inhalation particle matter (PM₁₀) in Lanzhou, the health risk of polycyclic aromatic hydrocarbons (PAHs) and benzo [a] pyrene (BaP) in PM₁₀ from the three fire power plants and the health risk of PAHs and BaP in PM₁₀ at the receptor point by inhalation exposure in heating and non-heating seasons was calculated, respectively. Then the contribution rates of the health risk caused by the three fire power plants to the health risk at the receptor point were calculated. The results showed that the contribution rates were not associated with sex and age, but were associated with time period and risk types. The contribution rates in the non-heating seasons were greater than those in heating seasons, and the contribution rates of the carcinogenic risk index were greater than those of the cancer risk value. The reliability of the established method was validated by comparing with the traditional method. This method was applicable to health risk assessment of toxic pollutants from all fixed sources and environmental risk assessment of environmental impact assessment. PMID:27506015

    Sexual obsessions are a common symptom of obsessive-compulsive disorder (OCD), often classified in a broader symptom dimension that includes aggressive and religious obsessions, as well. Indeed, the Dimensional Obsessive-Compulsive Scale (DOCS) Unacceptable Thoughts Scale includes obsessional content relating to sexual, violent, and religious themes associated with rituals that are often covert. However, there is reason to suspect that sexual obsessions differ meaningfully from other types of unacceptable thoughts. We conducted two studies to evaluate the factor structure, initial psychometric characteristics, and associated clinical features of a new DOCS scale for sexually intrusive thoughts (SIT). In the first study, nonclinical participants (N = 475) completed the standard DOCS with additional SIT questions and we conducted an exploratory factor analysis on all items and examined clinical and cognitive correlates of the different scales, as well as test-retest reliability. The SIT Scale was distinct from the Unacceptable Thoughts Scale and was predicted by different obsessional cognitions. It had good internal consistency and there was evidence for convergent and divergent validity. In the second study, we examined the relationships among the standard DOCS and SIT scales, as well as types of obsessional cognitions and symptom severity, in a clinical sample of individuals with OCD (N = 54). There were indications of both convergence and divergence between the Unacceptable Thoughts and SIT scales, which were strongly correlated with each other. Together, the studies demonstrate the potential utility of assessing sexually intrusive thoughts separately from the broader category of unacceptable thoughts. PMID:26163717

    Over the last dozen years, many national and international expert groups have considered specific improvements to risk assessment. Many of their stated recommendations are mutually supportive, but others appear conflicting, at least in an initial assessment. This review identifies areas of consensus and difference and recommends a practical, biology-centric course forward, which includes: (1) incorporating a clear problem formulation at the outset of the assessment with a level of complexity that is appropriate for informing the relevant risk management decision; (2) using toxicokinetics and toxicodynamic information to develop Chemical Specific Adjustment Factors (CSAF); (3) using mode of action (MOA) information and an understanding of the relevant biology as the key, central organizing principle for the risk assessment; (4) integrating MOA information into dose-response assessments using existing guidelines for non-cancer and cancer assessments; (5) using a tiered, iterative approach developed by the World Health Organization/International Programme on Chemical Safety (WHO/IPCS) as a scientifically robust, fit-for-purpose approach for risk assessment of combined exposures (chemical mixtures); and (6) applying all of this knowledge to enable interpretation of human biomonitoring data in a risk context. While scientifically based defaults will remain important and useful when data on CSAF or MOA to refine an assessment are absent or insufficient, assessments should always strive to use these data. The use of available 21st century knowledge of biological processes, clinical findings, chemical interactions, and dose-response at the molecular, cellular, organ and organism levels will minimize the need for extrapolation and reliance on default approaches.

    Decamethylcyclopentasiloxane (D5) is a low-molecular-weight cyclic siloxane used primarily as an intermediate in the production of several widely-used industrial and consumer products and intentionally added to consumer products, personal products and some dry cleaning solvents. The global use requires consideration of consumer use information and risk assessment requirements from various sources and authoritative bodies. A global "harmonized" risk assessment was conducted to meet requirements for substance-specific risk assessments conducted by regulatory agencies such as USEPA's Integrated Risk Information System (IRIS), Health Canada and various independent scientific committees of the European Commission, as well as provide guidance for chemical safety assessments under REACH in Europe, and other relevant authoritative bodies. This risk assessment incorporates global exposure information combined with a Monte Carlo analysis to determine the most significant routes of exposure, utilization of a multi-species, multi-route physiologically based pharmacokinetic (PBPK) model to estimate internal dose metrics, benchmark modeling to determine a point of departure (POD), and a margin of safety (MOS) evaluation to compare the estimates of intake with the POD. Because of the specific pharmacokinetic behaviors of D5 including high lipophilicity, high volatility with low blood-to-air partition coefficients and extensive metabolic clearance that regulate tissue dose after exposure, the use of a PBPK model was essential to provide a comparison of a dose metric that reflects these processes. The characterization of the potential for adverse effects after exposure to D5 using a MOS approach based on an internal dose metric removes the subjective application of uncertainty factors that may be applied across various regulatory agencies and allows examination of the differences between internal dose metrics associated with exposure and those associated with adverse effects.

  13. Integrated approach for managing health risks at work--the role of occupational health nurses.

    Currently, many organizations are using a department-centered approach to manage health risks at work. In such a model, segregated departments are providing employee benefits such as health insurance, workers' compensation, and short- and long-term disability or benefits addressing work-life issues. In recent years, a new model has emerged: health and productivity management (HPM). This is an employee-centered, integrated approach, designed to increase efficiency, reduce competition for scarce resources, and increase employee participation in prevention activities. Evidence suggests that corporations using integrated HPM programs achieve better health outcomes for their employees, with consequent increased productivity and decreased absenteeism. Occupational health nurses are well positioned to assume leadership roles in their organizations by coordinating efforts and programs across departments that offer health, wellness, and safety benefits. To assume their role as change agents to improve employees' health, nurses should start using the language of business more often by improving their communication skills, computer skills, and ability to quantify and articulate results of programs and services to senior management.

    Purpose The purpose of this article was to summarize scientific knowledge from an expert panel on reproductive health among adolescents with type 2 diabetes (T2D). Methods Using a mental model approach, a panel of experts—representing perspectives on diabetes, adolescents, preconception counseling, and reproductive health—was convened to discuss reproductive health issues for female adolescents with T2D. Results Several critical issues emerged. Compared with adolescents with type 1 diabetes, (1) adolescents with T2D may perceive their disease as less severe and have less experience managing it, putting them at risk for complications; (2) T2D is more prevalent among African Americans, who may be less trusting of the medical establishment; (3) T2D is associated with obesity, and it is often difficult to change one’s lifestyle within family environments practicing sedentary and dietary behaviors leading to obesity; (4) teens with T2D could be more fertile, because obesity is related to earlier puberty; (5) although obese teens with T2D have a higher risk of polycystic ovary syndrome, which is associated with infertility, treatment with metformin can increase fertility; and (6) women with type 2 diabetes are routinely transferred to insulin before or during pregnancy to allow more intensive management. Conclusions Findings from the expert panel provide compelling reasons to provide early, developmentally appropriate, culturally sensitive preconception counseling for teens with T2D. PMID:20944055

    The substance di-2-ethylhexyl phthalate (DEHP) is widely used as a plasticizer in chemical protective gloves to improve their flexibility and workability. However, it is possible that workers using protective gloves to handle various solvents may be exposed to DEHP leached by the solvents. Using an ASTM F739 permeation cell, it was found that BTEX solvents permeating through the glove samples dissolved DEHP from the gloves. Even without continuously contacting the permeant, DEHP was released from the contaminated glove samples during the desorption experiments. The DEHP leaching amounts were found to be inversely correlated to the permeability coefficients of BTEX in the glove samples. This result implied that the larger the amount of DEHP released from the glove samples, the higher the permeation resistance of gloves. Although chemical protective gloves provide adequate skin exposure protection to workers, the dermal exposure model developed herein indicates that leaching of DEHP from the glove samples may pose a potential health risk to the workers who handle BTEX. This study suggests that the selection of protective gloves should not only be concerned with the chemical resistance of the gloves but also the health risk associated with leaching of chemicals, such as DEHP, used in the manufacturing of the gloves.

    A survey on the reproductive health risk behaviors of adolescent students in Colombia was conducted. 230 9th and 11th graders participated in a survey using the Centers for Disease Control and Prevention's self-administered Youth Risk Behavior Survey. The sample was composed of 62% females and 38% males, aged 13-18 years. It was found that 29% had engaged in sexual intercourse; among these, 13% were 9th graders and 43% were 11th graders. Increasing age and male gender were significantly correlated with past sexual activity. Older males have more prevalent sexual activity than older females, while younger adolescents showed no gender differences. Male gender was significantly associated with early age of initiation of intercourse. Furthermore, 48% reported using contraception during their last sexual encounter, of which 63% used an effective method (condom, oral contraception, withdrawal) and 37% used a method of low or unknown efficacy. Use of alcohol prior to the last sexual intercourse accounted for 14%. The majority of the participants had discussed or received information on HIV infection at school (92%) or from family (77%). Results showed unmet health needs of the adolescent groups and lower frequency of contraceptive use. PMID:10195806

    During the process of treating and recycling Municipal Solid Waste Incinerators (MSWIs) fly ash, polychlorinated dibenzo-p-dioxins (PCDD/Fs) and polychlorinated dibenzofurans (dl-PCBs) in fly ash may potentially mobilize in the atmosphere and be widely distributed in the environment because of the inevitable re-suspension. Thus, this work presents the distributions of PCDD/Fs and dl-PCBs in inhalable coarse particles (Dp10-2.5 (particle diameter in μm)), fine particles (Dp<2.5) of fly ash and original fly ash from four MSWI plants in China. The results show that PCDD/Fs and dl-PCBs preferentially concentrated in Dp10-2.5 and Dp<2.5. Their mass concentrations and TEQ were significantly higher than those in the original fly ash, but the distribution of PCDD/Fs congeners in Dp10-2.5 and Dp<2.5 was close to that in the original fly ash. The main TEQ contribution included 1,2,3,7,8-PeCDD, 2,3,7,8-TeCDD in PCDDs and 2,3,4,7,8-PeCDF in PCDFs for Dp10-2.5, Dp<2.5 fractions and the original fly ash. Furthermore, the mass and TEQ contribution of dl-PCBs was relatively low. In addition, compared with the fluidized bed, the samples from the grate-type furnaces had significantly lower dioxin concentrations. In terms of potential health risk, the non-carcinogenic risk of PCDD/Fs in Dp10-2.5 and Dp<2.5 were estimated at 9.87 × 10(-1) to 4.81 and 1.19-7.95. For the carcinogenic risk of PCDD/Fs, both accumulation of Hazard Quotients (HQ) in Dp10-2.5 and Dp<2.5 exceeded the threshold limit and should be considered as unacceptable risk for onsite workers. The above findings could provide data to support the risk management of MSWI fly ash during the process of recycle and disposal. PMID:26873013

    Rationale: Recent U.S. data suggest an increased risk of work-related asthma among health care workers, yet only a few specific determinants have been elucidated. Objectives: To evaluate associations of asthma prevalence with occupational exposures in a cross-sectional survey of health care professionals. Methods: A detailed questionnaire was mailed to a random sample (n = 5,600) of all Texas physicians, nurses, respiratory therapists, and occupational therapists with active licenses in 2003. Information on asthma symptoms and nonoccupational asthma risk factors obtained from the questionnaire was linked to occupational exposures derived through an industry-specific job-exposure matrix. Measurements: There were two a priori defined outcomes: (1) physician-diagnosed asthma with onset after entry into health care (“reported asthma”) and (2) “bronchial hyperresponsiveness–related symptoms,” defined through an 8-item symptom-based predictor. Main Results: Overall response rate was 66%. The final study population consisted of 862 physicians, 941 nurses, 968 occupational therapists, and 879 respiratory therapists (n = 3,650). Reported asthma was associated with medical instrument cleaning (odds ratio [OR], 2.22; 95% confidence interval [CI], 1.34–3.67), general cleaning (OR, 2.02; 95% CI, 1.20–3.40), use of powdered latex gloves between 1992 and 2000 (OR, 2.17; 95% CI, 1.27–3.73), and administration of aerosolized medications (OR, 1.72; 95% CI, 1.05–2.83). The risk associated with latex glove use was not apparent after 2000. Bronchial hyperresponsiveness–related symptoms were associated with general cleaning (OR, 1.63; 95% CI, 1.21–2.19), aerosolized medication administration (OR, 1.40; 95% CI, 1.06–1.84), use of adhesives on patients (OR, 1.65; 95% CI, 1.22–2.24), and exposure to a chemical spill (OR, 2.02; 95% CI, 1.28–3.21). Conclusions: The contribution of occupational exposures to asthma in health care professionals is not trivial

    Hair dyes and their ingredients have moderate to low acute toxicity. Human poisoning accidents are rare and have only been reported following oral ingestion. Contact sensitisation to hair dyes has been a safety issue, mainly as a consequence of unprotected professional exposure. Although the use of hair dyes has dramatically increased in industrialised countries during the last decades, the prevalence of sensitisation to hair dyes in the general and professional populations has stabilised or declined. In vitro genotoxicity tests on hair dye ingredients frequently had positive results, although their correlation with in vivo carcinogenicity for the chemical class of oxidative hair dye ingredients (aromatic amines) is uncertain. Positive in vivo genotoxicity results on hair dyes are rare. Studies in man found no evidence of genotoxic effects of hair dyes or their ingredients. On the basis of mechanistic studies, some in vivo positive hair dye ingredients (p-aminophenol, Lawsone) have been shown to pose no or negligible risk to human health. Although a recent case-control epidemiology study suggested an association of hair dye use and bladder cancer, a number of other studies, including prospective investigations on large populations, found no or negative correlations for bladder or other cancers. Although in vivo topical carcinogenicity studies on hair dye ingredients or commercial formulations yielded no evidence for systemic toxicity or carcinogenicity, oral carcinogenicity studies on hair dye ingredients at oral doses up to the maximum tolerated dose (MTD) suggested that some ingredients are carcinogenic in rodents. Human systemic exposure to various (14)C-labelled oxidative hair dyes under conditions of use was below 1.0% of the amount applied. Conservative risk assessments suggested no or negligible cancer risk, including for ingredients that were found to be positive in oral carcinogenicity studies.

    In the past, human risk assessment was used almost exclusively to determine remedial measures at contaminated waste sites. Recently, however, ecological risk assessments have gained importance in evaluating risk not only to plants and animals, but also to humans through use of measures such as action levels of chemicals in fish tissue. Biological surveys were initiated to assess the mercury concentrations in finfish and shellfish in Lavaca Bay, Texas, part of which has been closed to fish and shellfish consumption since 1988 due to high levels of mercury in these organisms. Samples of particulate organic matter, cordgrass, invertebrates and fish were collected and analyzed for mercury concentrations. In conjunction with the biological surveys, an extensive sediment sampling program was conducted to map mercury concentrations in the sediment throughout the bay. A food web pathways model developed by personnel at National Marine Fisheries Service to assess mercury uptake by aquatic organisms in the bay has enabled the authors to concentrate on specific locations/habitats where mercury concentrations in sediment exceed a critical value. Biological data, along with stable isotope analyses, were used to validate the food web model. The conclusion is that mercury is continuing to enter the food web through the sediment-based food chain and not through the water column. These studies will be used to identify areas which need to be addressed for possible remedial measures, resulting in less uptake and bioaccumulation of mercury, and possible future removal of the fishing ban, thus establishing a direct linkage with human health concerns.

    Produced water generated during the production of oil and gas can contain enhanced levels of radium. This naturally occurring radioactive material (NORM) is discharged into freshwater streams, estuarine, coastal and outer continental shelf waters. Large volumes of produced waters are discharged to coastal waters along the Gulf Coast of Louisiana. The Gulf of Mexico is an important producer of fish and shellfish, and there is concern that radium discharged to coastal Louisiana could contaminate fish and shellfish used by people for food, and present a significant increase in cancer risk. This paper describes a screening-level assessment of the potential cancer risks posed by radium discharged to coastal Louisiana in oil-field produced waters. This screening analysis was performed to determine if a more comprehensive and realistic assessment is necessary, and because of the conservative assumptions embedded in the analysis overestimates the risk associated with the discharge of radium in produced waters. Two isotopes of radium (Ra-226 and Ra-228) are the radionuclides of most concern in produced water in terms of potential human health effects.

  4. Health benefits of 'grow your own' food in urban areas: implications for contaminated land risk assessment and risk management?

    Compelling evidence of major health benefits of fruit and vegetable consumption, physical activity, and outdoor interaction with 'greenspace' have emerged in the past decade - all of which combine to give major potential health benefits from 'grow-your-own' (GYO) in urban areas. However, neither current risk assessment models nor risk management strategies for GYO in allotments and gardens give any consideration to these health benefits, despite their potential often to more than fully compensate the risks. Although urban environments are more contaminated by heavy metals, arsenic, polyaromatic hydrocarbons and dioxins than most rural agricultural areas, evidence is lacking for adverse health outcomes of GYO in UK urban areas. Rarely do pollutants in GYO food exceed statutory limits set for commercial food, and few people obtain the majority of their food from GYO. In the UK, soil contamination thresholds triggering closure or remediation of allotment and garden sites are based on precautionary principles, generating 'scares' that may negatively impact public health disproportionately to the actual health risks of exposure to toxins through own-grown food. By contrast, the health benefits of GYO are a direct counterpoint to the escalating public health crisis of 'obesity and sloth' caused by eating an excess of saturated fats, inadequate consumption of fresh fruit and vegetables combined with a lack of exercise. These are now amongst the most important preventable causes of illness and death. The health and wider societal benefits of 'grow-your-own' thus reveal a major limitation in current risk assessment methodologies which, in only considering risks, are unable to predict whether GYO on particular sites will, overall, have positive, negative, or no net effects on human health. This highlights a more general need for a new generation of risk assessment tools that also predict overall consequences for health to more effectively guide risk management in our

    Cheryl Cox MacPherson recently argued, in an article for this journal, that 'Climate Change is a Bioethics Problem'. This article elaborates on that position, particularly highlighting bioethicists' potential ability to help reframe the current climate change discourse to give more attention to its health risks. This reframing process is especially important because of the looming problem of climate change skepticism. Recent empirical evidence from science framing experiments indicates that the public reacts especially positively to climate change messages framed in public health terms, and bioethicists are particularly well positioned to contribute their expertise to the process of carefully developing and communicating such messages. Additionally, as climate framing research and practice continue, it will be important for bioethicists to contribute to the creation of that project's nascent ethical standards. The discourse surrounding antibiotic resistance is posited as an example that can lend insight into how communicating a public health-framed message, including the participation of bioethicists, can help to override public skepticism about the findings of politically contentious scientific fields.

    Arsenic (As) is a major global environmental pollutant due to its high toxicity on human and animal health. This study collected 427 relevant papers to study As concentrations in Chinese arable soil and evaluate the health risk of exposure to As for humans. Results showed that the average of As concentration was 9.46 mg/kg in Chinese arable soil. Soil As concentrations in Hunan Province and Guangxi Zhuang Autonomous Region posed high carcinogenic and non-cancer risks on human health through diet, Yunnan, Guizhou, Guangdong, and Xinjiang provinces had relative high health risks, while As concentrations in the other provinces posed low health risks on humans. The physical factors controlled the spatial pattern of health risk on a provincial scale, but the As-related human activities introduced high health risk on people, particularly the agricultural activities such as sewage irrigation and fertilizer application should be given more attention due to its large area.

    Risk assessment and safety planning are considered a cornerstone of mental health practice, yet limited research exists into how mental health nurses conceptualize 'risk' and how they engage with risk assessment and safety planning. The aim of the present study was to explore mental health nurses' practices and confidence in risk assessment and safety planning. A self-completed survey was administered to 381 mental health nurses in Ireland. The findings indicate that nurses focus on risk to self and risk to others, with the risk of suicide, self-harm, substance abuse, and violence being most frequently assessed. Risk from others and 'iatrogenic' risk were less frequently considered. Overall, there was limited evidence of recovery-oriented practice in relation to risk. The results demonstrate a lack of meaningful engagement with respect to collaborative safety planning, the identification and inclusion of protective factors, and the inclusion of positive risk-taking opportunities. In addition, respondents report a lack of confidence working with positive risk taking and involving family/carers in the risk-assessment and safety-planning process. Gaps in knowledge about risk-assessment and safety-planning practice, which could be addressed through education, are identified, as are the implications of the findings for practice and research.

    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.

    Risk assessments of contaminated land often involve the use of generic bioconcentration factors (BCFs), which express contaminant concentrations in edible plant parts as a function of the concentration in soil, in order to assess the risks associated with consumption of homegrown vegetables. This study aimed to quantify variability in BCFs and evaluate the implications of this variability for human exposure assessments, focusing on cadmium (Cd) and lead (Pb) in lettuce and potatoes sampled around 22 contaminated glassworks sites. In addition, risks associated with measured Cd and Pb concentrations in soil and vegetable samples were characterized and a probabilistic exposure assessment was conducted to estimate the likelihood of local residents exceeding tolerable daily intakes. The results show that concentrations in vegetables were only moderately elevated despite high concentrations in soil, and most samples complied with applicable foodstuff legislation. Still, the daily intake of Cd (but not Pb) was assessed to exceed toxicological thresholds for about a fifth of the study population. Bioconcentration factors were found to vary more than indicated by previous studies, but decreasing BCFs with increasing metal concentrations in the soil can explain why the calculated exposure is only moderately affected by the choice of BCF value when generic soil guideline values are exceeded and the risk may be unacceptable.

Noncompliance should be documented so the nurse is reminded of the need to consider compliance when caring for the client in the future. Documentation of report tracking and follow up, consent, client education, and discharge information contributes to improved quality of care and reduced risk of litigation. Client records should never be altered (i.e., changed) so the original entry is no longer visible. The SLIDE (Single Line, Initials, Date, Explanation) rule should be used. PMID:10865552

    Objectives Population-based health risk assessment and stratification are considered highly relevant for large-scale implementation of integrated care by facilitating services design and case identification. The principal objective of the study was to analyse five health-risk assessment strategies and health indicators used in the five regions participating in the Advancing Care Coordination and Telehealth Deployment (ACT) programme (http://www.act-programme.eu). The second purpose was to elaborate on strategies toward enhanced health risk predictive modelling in the clinical scenario. Settings The five ACT regions: Scotland (UK), Basque Country (ES), Catalonia (ES), Lombardy (I) and Groningen (NL). Participants Responsible teams for regional data management in the five ACT regions. Primary and secondary outcome measures We characterised and compared risk assessment strategies among ACT regions by analysing operational health risk predictive modelling tools for population-based stratification, as well as available health indicators at regional level. The analysis of the risk assessment tool deployed in Catalonia in 2015 (GMAs, Adjusted Morbidity Groups) was used as a basis to propose how population-based analytics could contribute to clinical risk prediction. Results There was consensus on the need for a population health approach to generate health risk predictive modelling. However, this strategy was fully in place only in two ACT regions: Basque Country and Catalonia. We found marked differences among regions in health risk predictive modelling tools and health indicators, and identified key factors constraining their comparability. The research proposes means to overcome current limitations and the use of population-based health risk prediction for enhanced clinical risk assessment. Conclusions The results indicate the need for further efforts to improve both comparability and flexibility of current population-based health risk predictive modelling approaches

    Background: Risk is a ubiquitous part of health care. Understanding how people respond to risks is important for predicting how populations make health decisions. Our objective was to seek preliminary descriptive insights into the attitude to health risk in the Canadian population and factors associated with heterogeneity in risk attitude. Methods: We used a large market-research panel to survey (in English and French) a representative sample of the Canadian general population that reflected the age, sex and geography of the population. The survey included the Health-Risk Attitude Scale, which predicts how a person resolves risky health decisions related to treatment, prevention of disease and health-related behaviour. In addition, we assessed participants' numeracy and risk understanding, as well as income band and level of education. We summarized the responses, and we explored the independent associations between demographics, numeracy, risk understanding and risk attitude in multivariable models. Results: Of 6780 respondents, 4949 (73.0%) were averse to health risks; however, but there was considerable heterogeneity in the magnitude of risk aversion. We found significant gradients of risk averse attitudes with increasing age and being female (p < 0.001) using the multivariable model. French-speaking participants appeared to be more risk averse than those who were English-speaking (p < 0.001), as were individuals scoring higher on the Subjective Numeracy Scale (p < 0.001). Interpreation: In general, Canadians were averse to health risks, but we found that a sizeable, identifiable group of risk takers exists. Heterogeneity in preferences for risk can explain variations in health care utilization in the context of patient-centred care. Understanding risk preference heterogeneity can help guide policy and assist in patient-physician decisions. PMID:27398375

    Emerging infectious diseases pose a growing threat to human populations. Many of the world's epidemic diseases (particularly those transmitted by intermediate hosts) are known to be highly sensitive to long-term changes in climate and short-term fluctuations in the weather. The application of environmental data to the study of disease offers the capability to demonstrate vector-environment relationships and potentially forecast the risk of disease outbreaks or epidemics. Accurate disease forecasting models would markedly improve epidemic prevention and control capabilities. This chapter examines the potential for epidemic forecasting and discusses the issues associated with the development of global networks for surveillance and prediction. Existing global systems for epidemic preparedness focus on disease surveillance using either expert knowledge or statistical modelling of disease activity and thresholds to identify times and areas of risk. Predictive health information systems would use monitored environmental variables, linked to a disease system, to be observed and provide prior information of outbreaks. The components and varieties of forecasting systems are discussed with selected examples, along with issues relating to further development.

    The use of ionizing radiation has been increased in recent years within medical applications. Nuclear Medicine Department offers both treatment and diagnosis of diseases using radioisotopes to controlled doses. Despite the great benefits to the patient, there is an inherent risk to workers which remains in contact with radiation sources for long periods. These personnel must be monitored to avoid deterministic effects. In this work, we retrospectively evaluated occupationally exposed personnel (OEP) to ionizing radiation in nuclear medicine during the last five years. We assessed both area and personal dosimetry of this department in a known Clinic in Sonora. Our results show an annual equivalent dose average of 4.49 ± 0.70 mSv in OEP without showing alarming changes in clinical parameters analyzed. These results allow us to conclude that health of OEP in nuclear medicine of this clinic has not been at risk during the evaluated period. However, we may suggest the use of individual profiles based on specific radiosensitivity markers.

  5. Selenium Health Benefit Values: Updated Criteria for Mercury Risk Assessments.

    Selenium (Se)-dependent enzymes (selenoenzymes) protect brain tissues against oxidative damage and perform other vital functions, but their synthesis requires a steady supply of Se. High methylmercury (CH3Hg) exposures can severely diminish Se transport across the placenta and irreversibly inhibit fetal brain selenoenzymes. However, supplemental dietary Se preserves their activities and thus prevents pathological consequences. The modified Se health benefit value (HBVSe) is a risk assessment criterion based on the molar concentrations of CH3Hg and Se present in a fish or seafood. It was developed to reflect the contrasting effects of maternal CH3Hg and Se intakes on fetal brain selenoenzyme activities. However, the original equation was prone to divide-by-zero-type errors whereby the calculated values increased exponentially in samples with low CH3Hg contents. The equation was refined to provide an improved index to better reflect the risks of CH3Hg exposures and the benefits provided by dietary Se. The HBVSe provides a biochemically based perspective that confirms and supports the FDA/EPA advice for pregnant and breast-feeding women regarding seafoods that should be avoided vs. those that are beneficial to consume. Since Se can be highly variable between watersheds, further evaluation of freshwater fish is needed to identify locations where fish with negative HBVSe may arise and be consumed by vulnerable subpopulation groups.

    In a longitudinal study of a birth cohort, the authors identified youth involved in each of 4 different health-risk behaviors at age 21: alcohol dependence, violent crime, unsafe sex, and dangerous driving habits. At age 18, the Multidimensional Personality Questionnaire (MPQ) was used to assess 10 distinct personality traits. At age 3, observational measures were used to classify children into distinct temperament groups. Results showed that a similar constellation of adolescent personality traits, with developmental origins in childhood, is linked to different health-risk behaviors at 21. Associations between the same personality traits and different health-risk behaviors were not an artifact of the same people engaging in different health-risk behaviors; rather, these associations implicated the same personality type in different but related behaviors. In planning campaigns, health professionals may need to design programs that appeal to the unique psychological makeup of persons most at risk for health-risk behaviors. PMID:9364760

  7. Mapping heatwave health risk at the community level for public health action

    2012-01-01

    Background Climate change poses unprecedented challenges, ranging from global and local policy challenges to personal and social action. Heat-related deaths are largely preventable, but interventions for the most vulnerable populations need improvement. Therefore, the prior identification of high risk areas at the community level is required to better inform planning and prevention. We aimed to demonstrate a simple and flexible conceptual framework relying upon satellite thermal data and other digital data with the goal of easily reproducing this framework in a variety of urban configurations. Results The study area encompasses Rennes, a medium-sized French city. A Landsat ETM + image (60 m resolution) acquired during a localized heatwave (June 2001) was used to estimate land surface temperature (LST) and derive a hazard index. A land-use regression model was performed to predict the LST. Vulnerability was assessed through census data describing four dimensions (socio-economic status, extreme age, population density and building obsolescence). Then, hazard and vulnerability indices were combined to deliver a heatwave health risk index. The LST patterns were quite heterogeneous, reflecting the land cover mosaic inside the city boundary, with hotspots of elevated temperature mainly observed in the city center. A spatial error regression model was highly predictive of the spatial variation in the LST (R2 = 0.87) and was parsimonious. Three land cover descriptors (NDVI, vegetation and water fractions) were negatively linked with the LST. A sensitivity analysis (based on an image acquired on July 2000) yielded similar results. Southern areas exhibited the most vulnerability, although some pockets of higher vulnerability were observed northeast and west of the city. The heatwave health risk map showed evidence of infra-city spatial clustering, with the highest risks observed in a north–south central band. Another sensitivity analysis gave a very high

  16. Cosmetics as endocrine disruptors: are they a health risk?

    PubMed

    Nicolopoulou-Stamati, Polyxeni; Hens, Luc; Sasco, Annie J

    2015-12-01

    Exposure to chemicals from different sources in everyday life is widespread; one such source is the wide range of products listed under the title "cosmetics", including the different types of popular and widely-advertised sunscreens. Women are encouraged through advertising to buy into the myth of everlasting youth, and one of the most alarming consequences is in utero exposure to chemicals. The main route of exposure is the skin, but the main endpoint of exposure is endocrine disruption. This is due to many substances in cosmetics and sunscreens that have endocrine active properties which affect reproductive health but which also have other endpoints, such as cancer. Reducing the exposure to endocrine disruptors is framed not only in the context of the reduction of health risks, but is also significant against the background and rise of ethical consumerism, and the responsibility of the cosmetics industry in this respect. Although some plants show endocrine-disrupting activity, the use of well-selected natural products might reduce the use of synthetic chemicals. Instruments dealing with this problem include life-cycle analysis, eco-design, and green labels; in combination with the committed use of environmental management systems, they contribute to "corporate social responsibility".

    2014-01-01

    Clinicians and clinical administrators should have a basic understanding of physical and financial risk to mental health facilities related to external physical threat, including actions usually viewed as "terrorism" and much more common sources of violence. This article refers to threats from mentally ill persons and those acting out of bizarre or misguided "revenge," extortionists and other outright criminals, and perpetrators usually identified as domestic or international terrorists. The principles apply both to relatively small and contained acts (such as a patient or ex-patient attacking a staff member) and to much larger events (such as bombings and armed attack), and are relevant to facilities both within and outside the U.S. Patient care and accessibility to mental health services rest not only on clinical skills, but also on a place to practice them and an organized system supported by staff, physical facilities, and funding. Clinicians who have some familiarity with the non-clinical requirements for care are in a position to support non-clinical staff in preventing care from being interrupted by external threats or events such as terrorist activity, and/or to serve at the interface of facility operations and direct clinical care. Readers should note that this article is an introduction to the topic and cannot address all local, state and national standards for hospital safety, or insurance providers' individual facility requirements.

    Environmental surfaces have been clearly linked to transmission of key pathogens in health care facilities, including methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus, Clostridium difficile, norovirus, and multidrug-resistant gram-negative bacilli. For this reason, routine disinfection of environmental surfaces in patient rooms is recommended. In addition, decontamination of shared medical devices between use by different patients is also recommended. Environmental surfaces and noncritical shared medical devices are decontaminated by low-level disinfectants, most commonly phenolics, quaternary ammonium compounds, improved hydrogen peroxides, and hypochlorites. Concern has been raised that the use of germicides by health care personnel may increase the risk of these persons for developing respiratory illnesses (principally asthma) and contact dermatitis. Our data demonstrate that dermatitis and respiratory symptoms (eg, asthma) as a result of chemical exposures, including low-level disinfectants, are exceedingly rare. Unprotected exposures to high-level disinfectants may cause dermatitis and respiratory symptoms. Engineering controls (eg, closed containers, adequate ventilation) and the use of personal protective equipment (eg, gloves) should be used to minimize exposure to high-level disinfectants. The scientific evidence does not support that the use of low-level disinfectants by health care personnel is an important risk for the development of asthma or contact dermatitis. PMID:27131141

    Background Non-communicable diseases (NCD) accounts for more than a third (37%) of all deaths in South Africa. However, this burden of disease can be reduced by addressing risk factors. The aim of this study was to determine the health and risk profile of South African employees presenting for health risk assessments and to measure their readiness to change and improve lifestyle behaviour. Methods Employees (n = 1954) from 18 companies were invited to take part in a wellness day, which included a health-risk assessment. Self-reported health behaviour and health status was recorded. Clinical measures included cholesterol finger-prick test, blood pressure and Body Mass Index (BMI). Health-related age was calculated using an algorithm incorporating the relative risk for all case mortality associated with smoking, physical activity, fruit and vegetable intake, BMI and cholesterol. Medical claims data were obtained from the health insurer. Results The mean percentage of participation was 26% (n = 1954) and ranged from 4% in transport to 81% in the consulting sector. Health-related age (38.5 ± 12.9 years) was significantly higher than chronological age (34.9 ± 10.3 yrs) (p < 0.001). Both chronological and risk-related age were significantly different between the sectors (P < 0.001), with the manufacturing sector being the oldest and finance having the youngest employees. Health-related age was significantly associated with number of days adversely affected by mental and physical health, days away from work and total annual medical costs (p < 0.001). Employees had higher rates of overweight, smoking among men, and physical inactivity (total sample) when compared the general SA population. Increased health-related expenditure was associated with increased number of risk factors, absenteeism and reduced physical activity. Conclusion SA employees' health and lifestyle habits are placing them at increased risk for NCD's, suggesting that they may develop NCD's earlier than

  20. Perceived extrinsic mortality risk and reported effort in looking after health: testing a behavioral ecological prediction.

    PubMed

    Pepper, Gillian V; Nettle, Daniel

    2014-09-01

    Socioeconomic gradients in health behavior are pervasive and well documented. Yet, there is little consensus on their causes. Behavioral ecological theory predicts that, if people of lower socioeconomic position (SEP) perceive greater personal extrinsic mortality risk than those of higher SEP, they should disinvest in their future health. We surveyed North American adults for reported effort in looking after health, perceived extrinsic and intrinsic mortality risks, and measures of SEP. We examined the relationships between these variables and found that lower subjective SEP predicted lower reported health effort. Lower subjective SEP was also associated with higher perceived extrinsic mortality risk, which in turn predicted lower reported health effort. The effect of subjective SEP on reported health effort was completely mediated by perceived extrinsic mortality risk. Our findings indicate that perceived extrinsic mortality risk may be a key factor underlying SEP gradients in motivation to invest in future health. PMID:24990431

    2014-09-01

    Although the USA has made significant strides in reducing lead exposure, new and emerging sources are raising cause for public concern. Recent reports of finding lead in eggs from chickens raised in urban gardens has highlighted the need to consider the potential health risks of consuming eggs from backyard chickens. Following the detection of 0.33 μg/g lead in the edible portion of eggs submitted for lead analysis from a backyard chicken owner, further investigation was conducted to determine the source and extent of lead exposure in the flock. Several birds, almost two dozen eggs, and environmental samples were submitted to the California Animal Health and Food Safety Laboratory for further testing. Lead was detected in the blood, liver, kidney, and bone at varying concentrations in all birds but was not detected in the muscle tissue. All egg shells contained detectable amounts of lead, while only a little over half of the edible portion of the eggs contained lead. The detected concentrations in the edible portion approached or exceeded the recommended threshold of lead consumption per day that should not be exceeded by young children if a child consumed one average-sized egg. Peeling paint from a wooded structure adjacent to the flock's coop was the likely lead source containing 3,700 μg/g lead. Thus, removal of the chickens from the source and periodic testing of eggs for lead were recommended. This case illustrates the need for consumers and health care workers to be aware of potential sources for lead exposure such as backyard chickens. PMID:24943230

    Recent observed changes in Earth's climate, to which humans have contributed substantially, are affecting various health outcomes. These include altered distributions of some infectious disease vectors (ticks at high latitudes, malaria mosquitoes at high altitudes), and an uptrend in extreme weather events and associated deaths, injuries and other health outcomes. Future climate change, if unchecked, will have increasing, mostly adverse, health impacts - both direct and indirect. Climate change will amplify health problems in vulnerable regions, influence infectious disease emergence, affect food yields and nutrition, increase risks of climate-related disasters and impair mental health. The health sector should assist society understand the risks to health and the needed responses. PMID:21682780

  5. Withholding differential risk information on legal consumer nicotine/tobacco products: The public health ethics of health information quarantines.

    PubMed

    Kozlowski, Lynn T; Sweanor, David

    2016-06-01

    The United States provides an example of a country with (a) legal tobacco/nicotine products (e.g., snus, other smokeless tobacco, cigarettes) differing greatly in risks to health and (b) respected health information websites that continue to omit or provide incorrect differential risk information. Concern for the principles of individual rights, health literacy, and personal autonomy (making decisions for oneself), which are key principles of public health ethics, has been countered by utilitarian arguments for the use of misleading or limited information to protect public health overall. We argue that omitting key health relevant information for current or prospective consumers represents a kind of quarantine of health-relevant information. As with disease quarantines, the coercive effects of quarantining information on differential risks need to be justified, not merely by fears of net negative public health effects, but by convincing evidence that such measures are actually warranted, that public health overall is in imminent danger and that the danger is sufficient to override principles of individual autonomy. Omitting such health-relevant information for consumers of such products effectively blindfolds them and impairs their making informed personal choices. Moral psychological issues that treat all tobacco/nicotine products similarly may also be influencing the reluctance to inform on differential risks. In countries where tobacco/nicotine products are legally sold and also differ greatly in disease risks compared to cigarettes (e.g., smokeless tobacco and vape), science-based, comprehensible, and actionable health information (consistent with health literacy principles) on differential risks should be available and only reconsidered if it is established that this information is causing losses to population health overall.

    OBJECTIVE To analyze the relationships between sexual behavior and risk factors to physical and mental health in adolescents. METHODS Study of 3,195 pupils aged 15 to 19 in secondary education, in public and private schools in 10 state capitals in Brazil between 2007 and 2008. Multi-stage (schools and pupils) cluster sampling was used in each city and public and private educational network. All of the students selected completed a questionnaire on the following items: socioeconomic and demographic data; sexual behavior; having sex with those of the same sex, the opposite sex, or both; alcohol and cannabis use; using condoms; traumatic sexual experiences as a child or adolescent; suicidal thoughts. The analysis included describing frequencies, Chi-square test, analysis of multiple and cluster correspondence. Responses to an open ended question in which the adolescent expressed general comments about themselves and their lives were qualitatively analyzed using content analysis. RESULTS Around 3.0% of adolescents reported homosexual or bisexual behavior, with no difference according to sex, age, skin color, social status family structure or educational network. Adolescents with homosexual/bisexual sexual behavior, compared to their heterosexual peers, reported: (p < 0.05): getting drunk (18.7% and 10.5%, respectively), frequent cannabis use (6.1% and 2.1%, respectively), suicidal thoughts (42.5% and 18.7%, respectively), and having been the victim of sexual violence (11.7% and 1.5%; respectively). Adolescents with homosexual/bisexual sexual behavior reported that they used condoms less frequently (74.2%) than their heterosexual peers (48.6%, p < 0.001). In the correspondence analysis, three groups were found, one composed of adolescents with homosexual/bisexual behavior and experiencing risk factors; suffering sexual violence, never using a condom, suicidal thoughts, frequent cannabis use; another composed of occasional cannabis and condom users, who got drunk

    The risk to human health from fragments of depleted uranium (DU) at Jefferson Proving Ground (JPG) was estimated using two types of ecosystem pathway models. A steady-state, model of the JPG area was developed to examine the effects of DU in soils, water, and vegetation on deer that were hunted and consumed by humans. The RESRAD code was also used to estimate the effects of farming the impact area and consuming the products derived from the farm. The steady-state model showed that minimal doses to humans are expected from consumption of deer that inhabit the impact area. Median values for doses to humans range from about 1 mrem ({plus_minus}2.4) to 0.04 mrem ({plus_minus}0.13) and translate to less than 1 {times} 10{sup {minus}6} detriments (excess cancers) in the population. Monte Carlo simulation of the steady-state model was used to derive the probability distributions from which the median values were drawn. Sensitivity analyses of the steady-state model showed that the amount of DU in airborne dust and, therefore, the amount of DU on the vegetation surface, controlled the amount of DU ingested by deer and by humans. Human doses from the RESRAD estimates ranged from less than 1 mrem/y to about 6.5 mrem/y in a hunting scenario and subsistence fanning scenario, respectively. The human doses exceeded the 100 mrem/y dose limit when drinking water for the farming scenario was obtained from the on-site aquifer that was presumably contaminated with DU. The two farming scenarios were unrealistic land uses because the additional risk to humans due to unexploded ordnance in the impact area was not figured into the risk estimate. The doses estimated with RESRAD translated to less than 1 {times} 10{sup {minus}6} detriments to about 1 {times} 10{sup {minus}3} detriments. The higher risks were associated only with the farming scenario in which drinking water was obtained on-site.

    Purpose Suspected diabetogenic effects or drug indication may increase testing for diabetes mellitus (DM), resulting in measurement bias when evaluating diabetogenic drug effects. We sought to evaluate the validity of electronic health record data in determining DM risk. Methods We used time-dependent Cox proportional hazard models within a retrospective cohort design to assess associations between use of antihypertensives, statins, atypical antipsychotics, and antidepressants, and two endpoints: (i) DM onset defined as fasting blood glucose (BG) ≥126 mg/dl, random BG ≥200 mg/dl, HbA1c ≥7.0%, or antidiabetic drug initiation; and (ii) first negative DM test. We used Poisson regression to assess the influence of these drugs on DM testing rates. Patients aged 35–64 years enrolled in Kaiser Permanente Northwest between 1997 and 2010 entered the cohort at the first negative BG test after ≥6 months without manifest DM. Results All drug classes showed significant associations not only with DM onset but also with first negative BG test and with DM testing rates. Antipsychotics had the greatest diabetogenic risk (adjusted hazard ratio [HR] = 1.73 [1.44–2.08]), the greatest propensity for a first negative test (adjusted HR = 1.87 [1.74–2.01]), and the highest testing rate (adjusted rate ratio = 1.76 [1.72–1.81]. Although renin–angiotensin system blockers and calcium channel blockers have shown no diabetogenic risk in clinical trials, both were associated with DM (HR = 1.19 [1.12–1.26] and 1.27 [1.17–1.38]), a negative glucose test (1.38 [1.35–1.41] and 1.24 [1.20–1.28]), and increased testing rates (rate ratio = 1.26 [1.24–1.27] and 1.27 [1.25–1.28]). Conclusion Caution should be used when diabetogenic risk is evaluated using data that rely on DM testing in general practice. PMID:24923707

    There are many health-risk behaviors that may elevate the risk of adolescents engaging in teenage dating violence. The purpose of this investigation was to examine the health-risk behaviors that are associated with a sample of female juvenile offenders to identify the extent to which those behaviors contribute to dating violence. The survey assessed respondents' health-risk behaviors prior to incarceration, their perceptions of quality of life, post-incarceration expectations, psychosocial factors, and other social determinants. Results indicated youth exposure to dating violence, alcohol, drug, and risky sexual behaviors in the year prior to incarceration. These findings demonstrate the need to address teen dating violence with at-risk adolescents in addition to risky behaviors. PMID:26408099

    Risk perceptions are only slightly correlated with the expected values of a probability distribution for negative health impacts. Psychometric studies have documented that context variables such as dread or personal control are important predictors for the perceived seriousness of risk. Studies about cultural patterns of risk perceptions emphasize different response sets to risk information, depending on cultural priorities such as social justice versus personal freedom. This chapter reports the major psychological research results pertaining to the factors that govern individual risk perception and discusses the psychometric effects due to people's risk perception and the experience of severe stress. The relative importance of the psychometric context variables, the signals pertaining to each health risks and symbolic beliefs are explained. PMID:9339320

    Objectives To evaluate dose-response associations between misperceived weight and 32 health risk behaviors in a nationally representative sample of US adolescents. Methods Participants included 13,864 US high school students in the 2011 Youth Risk Behavior Survey. Comparing the degree of agreement between perceived and reported actual weight, weight misperception was determined as 5 categories. Multivariable-adjusted logistic regression analyses evaluated associations of weight misperception with 32 health risk behaviors. Results Both underestimated and overestimated weight were statistically significantly associated with all 32 health risk behaviors in a dose-response manner after adjustment for age, sex and race/ethnicity, where greater weight misperception was associated with higher engagement in health risk behaviors. Conclusions Understanding potential impacts of weight misperception on health risk behaviors could improve interventions that encourage healthy weight perception and attainment for adolescents.

    Risk managers often meet with health care workers who are emotionally traumatized following adverse events. We surveyed members of the American Society for Health care Risk Management (ASHRM) about their training, experience, competence, and comfort with providing emotional support to health care workers. Although risk managers reported feeling comfortable and competent in providing support, nearly all respondents prefer to receive additional training. Risk managers who were comfortable listening to and supporting health care workers were more likely to report prior training. Health care organizations implementing second victim support programs should not rely solely on risk managers to provide support, rather engage and train interested risk managers and provide them with opportunities to practice.

    This study assessed the concentrations of heavy metals such as cadmium (Cd), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni) and zinc (Zn) in agricultural soils and crops (fruits, grains and vegetable) and their possible human health risk in Swat District, northern Pakistan. Cd concentration was found higher than the limit (0.05 mg/kg) set by world health organization in 95% fruit and 100% vegetable samples. Moreover, the concentrations of Cr, Cu, Mn, Ni and Zn in the soils were shown significant correlations with those in the crops. The metal transfer factor (MTF) was found highest for Cd followed by Cr>Ni>Zn>Cu>Mn, while the health risk assessment revealed that there was no health risk for most of the heavy metals except Cd, which showed a high level of health risk index (HRI⩾10E-1) that would pose a potential health risk to the consumers.

    2000-01-01

    Environmental health risk assessment is increasingly being used in the development of environmental health policies, public health decision making, the establishment of environmental regulations, and research planning. The credibility of risk assessment depends, to a large extent, on the strength of the scientific evidence on which it is based. It is, therefore, imperative that the processes and methods used to evaluate the evidence and estimate health risks are clear, explicit, and based on valid epidemiological theory and practice. Epidemiological Evidence for Environmental Health Risk Assessment is a World Health Organization (WHO) guideline document. The primary target audiences of the guidelines are expert review groups that WHO (or other organizations) might convene in the future to evaluate epidemiological evidence on the health effects of environmental factors. These guidelines identify a set of processes and general approaches to assess available epidemiological information in a clear, consistent, and explicit manner. The guidelines should also help in the evaluation of epidemiological studies with respect to their ability to support risk assessment and, consequently, risk management. Conducting expert reviews according to such explicit guidelines would make health risk assessment and subsequent risk management and risk communication processes more readily understood and likely to be accepted by policymakers and the public. It would also make the conclusions reached by reviews more readily acceptable as a basis for future WHO guidelines and other recommendations, and would provide a more rational basis for setting priorities for future research.

    Inhalable particulate matter (PM10) is a primary air pollutant closely related to public health, and an especially serious problem in urban areas. The urban heat island (UHI) effect has made the urban PM10 pollution situation more complex and severe. In this study, we established a health risk assessment system utilizing an epidemiological method taking the thermal environment effects into consideration. We utilized a remote sensing method to retrieve the PM10 concentration, UHI, Normalized Difference Vegetation Index (NDVI), and Normalized Difference Water Index (NDWI). With the correlation between difference vegetation index (DVI) and PM10 concentration, we utilized the established model between PM10 and thermal environmental indicators to evaluate the PM10 health risks based on the epidemiological study. Additionally, with the regulation of UHI, NDVI and NDWI, we aimed at regulating the PM10 health risks and thermal environment simultaneously. This study attempted to accomplish concurrent thermal environment regulation and elimination of PM10 health risks through control of UHI intensity. The results indicate that urban Beijing has a higher PM10 health risk than rural areas; PM10 health risk based on the thermal environment is 1.145, which is similar to the health risk calculated (1.144) from the PM10 concentration inversion; according to the regulation results, regulation of UHI and NDVI is effective and helpful for mitigation of PM10 health risk in functional zones.

    This study intends to assess the potential health hazards of drinking water quality and explore the application of geographic information system( GIS) in drinking water safety in Tianjin. Eight hundred and fifty water samples from 401 sampling points in Tianjin were measured according to the national drinking water standards. The risk assessment was conducted using the environmental health risk assessment model recommended by US EAP, and GIS was combined to explore the information visualization and risk factors simultaneously. The results showed that the health risks of carcinogens, non-carcinogens were 3.83 x 10⁻⁵, 5.62 x 10⁻⁹ and 3.83 x 10⁻⁵ for total health risk respectively. The rank of health risk was carcinogen > non-carcinogen. The rank of carcinogens health risk was urban > new area > rural area, chromium (VI) > cadmium > arsenic > trichlormethane > carbon tetrachloride. The rank of non-carcinogens health risk was rural area > new area > urban, fluoride > cyanide > lead > nitrate. The total health risk level of drinking water in Tianjin was lower than that of ICRP recommended level (5.0 x 10⁻⁵), while was between US EPA recommended level (1.0 x 10⁻⁴-1.0 x 10⁻⁶). It was at an acceptable level and would not cause obvious health hazards. The main health risks of drinking water came from carcinogens. More attentions should be paid to chromium (VI) for carcinogens and fluoride for non-carcinogens. GIS can accomplish information visualization of drinking water risk assessment and further explore of risk factors. PMID:27011993

    An inventory of air pollution sources within the Athens basin is carried out for the years 1989, 1992 and 1998 and the results are inputted in a climatological model for predicting ambient concentrations. Despite of the significant growth in the number of road vehicles and the deteriorating traffic, the emissions and ambient concentrations of fine particulates, CO, NOx and VOC appear to remain reasonably constant over for the period 1989 to 1998, while these of SO2 and Pb are reduced, mainly due to the renewal of vehicle fleet, the use of catalytic technologies and the improved quality of the used fuel. The results further indicate that for CO, NOx and VOC the major source is road traffic, while for PM2.5 and SO2 both space heating and traffic share responsibility. The air pollutant concentrations monitored by the network of 11 stations are reviewed and statistics related to air quality guidelines are presented. As fine particulate levels are not monitored, approximate PM2.5 and PM10 concentrations are derived from black smoke ones on basis of experimentally determined conversion factors. The computed and monitored air pollution levels are compared and found in reasonable agreement. The results of the above analysis show that the levels of all 'classical' pollutants, with the exception of SO2 and Pb, exceed significantly the WHO guidelines and are thus expected to exert a significant health impact. The latter could be quantified in relation to the PM2.5 or PM10 levels on the basis of risk assessment information developed by the World Health Organization (WHO). The results show that the existing levels of fine particle concentrations in Athens increase significantly the mortality and morbidity, and reduce the average longevity of the entire population from 1.3 to 1.7 years.

    The purposes of this review are to assess the human exposure and human and experimental evidence for adverse effects of brominated flame-retardants (BFRs) with specific focus on intake from seafood. The leakage of BFRs from consumer products leads to exposure of humans from fetal life to adulthood. Fish and fish products contain the highest levels of BFRs and dominate the dietary intake of frequent fish eaters in Europe, while meat, followed by seafood and dairy products accounted for the highest US dietary intake. House dust is also reported as an important source of exposure for children as well as adults. The levels of BFRs in the general North American populations are higher than those in Europe and Japan and the highest levels are detected in infants and toddlers. The daily intake via breast milk exceeds the RfD in 10% of US infants. BFRs including PBDEs, HBCDs and TBBP-A have induced endocrine-, reproductive- and behavior effects in laboratory animals. Furthermore, recent human epidemiological data demonstrated association between exposure to BFRs and similar adverse effects as observed in animal studies. Fish including farmed fish and crude fish oil for human consumption may contain substantial levels of BFRs and infants and toddlers consuming these products on a daily basis may exceed the tolerable daily intake suggesting that fish and fish oil alone represent a risk to human health. This intake comes in addition to exposure from other sources (breast milk, other food, house dust). Because potential harmful concentrations of BFRs and other toxicants occur in fish and fish products, research on a wider range of products is warranted, to assess health hazard related to the contamination of fish and fish products for human consumption.

    The development of industries in rural areas can aggravate the arsenic (As) contamination of the local environment, which may pose unacceptable health risks to the local residents. This paper estimated the health risk posed by inorganic As (iAs) to residents via ingestion of soil, skin contact with soil and consumption of foodstuffs in a typical rural- industrial developed town in southern Jiangsu, China. The average concentrations of total As in soil, rice, fish, shrimp and crab, pork and eggs, vegetables and fruits were detected to be 10.367, 0.104 mg/kg dw (dry weight), 0.050, 0.415, 0.011, 0.013 and 0.017 mg/kg fw (fresh weight), respectively. All of these values are below the maximum allowable concentration in food and soil in China. The deterministic estimation results showed that the hazard quotient (HQ) and excess lifetime cancer risk (R) were 1.28 (0.78-2.31) and 2.38 × 10(-4) (2.71 × 10(-5)-5.09 × 10(-4)) for all age groups, respectively. Males in the age range of 2-29 years and females in the age range of 2-13 years and 18-29 years exhibited non-carcinogenic risk (HQ>1). Carcinogenic risk exceeded the acceptable level of 1 × 10(-)(5) for both genders at all ages. Furthermore, this risk rose with age. The probabilistic estimation results showed that about 28% of residents had non-carcinogenic risk due to over ingestion of iAs. The R value of 90% of residents was greater than 10(-)(5). The sensitivity analysis indicated that the cancer slope factor (SF), the ingestion rates of rice and the iAs concentration in rice were the most relevant variables affecting the assessment outcome. Based on these results, it is recommended that residents reduce their consumption of rice, though it should be noted that the assessment outcome has uncertainty due to estimating iAs from foodstuffs and not considering the bioaccessibility of iAs in foodstuffs. Nevertheless, measures like reducing industrial As emissions, forbidding the use of pesticides, fertilizers and

    News about health disparities often compares health risks faced by different demographic groups. Does this social comparison produce a contrast effect? It was hypothesized that when two racial groups are compared, people would perceive the relatively more at-risk group to be more, and the less at-risk group to be less, at-risk than if the same risk information was presented without the comparative reference group. Three experiments with Black and White respondents tested effects of intergroup social comparison framing (SCF) on perceptions of risk for sexually transmitted infections and skin cancer. SCF (including one White and two Black disparity frames) did not raise respondents' perceived risk regarding the more at-risk racial group, but consistently lowered respondents' risk ratings for the less at-risk racial group. The finding that the same statistic was perceived differently in comparative and noncomparative contexts underscores the importance of considering effects of communication about disparities.

    The present survey was designed to investigate the perception of health risks among college students in China. The data are the responses of a sample of 3,069 college students at one university to surveys that include measures of several dimensions of public judgments about fifteen specific hazards. Chinese college students conveyed their concerns as falling into three broad categories: Environmental (e.g., global warming, natural catastrophes, the ozone hole, air pollution, chemical pollution, pesticides in food), Technological (e.g., nuclear power stations, thermal power, genetically modified food, medical X-rays), and Social (cigarette smoking, drinking alcohol, overtime study or work, mental stress, motor vehicle accidents). The data were collected with a self-report questionnaire. Descriptive statistics were used to illustrate the levels of perceived risk according to the percent of "high risk" responses as well as the mean response values. Generally, the hazards that were perceived as posing the greatest health risk were those belonging to the social health risks; items related to technology risks received the lowest percentage of "high health risk" rankings. Traditional environmental risks such as natural catastrophes, pollution issues (chemical pollution, air pollution), and pesticides in food were ranked as being relatively high risks. The respondents were less concerned about new emerging issues and long-term environmental risks (global warming). In this survey, motor vehicle accidents were considered to be a "high health risk" by the greatest percentage of respondents. Generally speaking, the female respondents' degree of recognition of health risks is higher than that of male respondents. Only for the item of smoking was the male respondents' degree higher than that of females. There is also a geographic imbalance in the health risk perceptions. The degree of recognition of health risks from respondents in municipalities is generally lower than that of

    News reporting on research studies may influence attitudes about health risk, support for public health policies, or attitudes towards people labeled as unhealthy or at risk for disease. Across five experiments (N = 2123) we examined how different news framings of obesity research influence these attitudes. We exposed participants to either a control condition, a news report on a study portraying obesity as a public health crisis, a news report on a study suggesting that obesity may not be as much of a problem as previously thought, or an article discussing weight-based discrimination. Compared to controls, exposure to the public health crisis article did not increase perception of obesity-related health risks but did significantly increase the expression of antifat prejudice in four out of seven comparisons. Across studies, compared to controls, participants who read an article about weight-based discrimination were less likely to agree that overweight constitutes a public health crisis or to support various obesity policies. Effects of exposure to an article questioning the health risks associated with overweight and obesity were mixed. These findings suggest that news reports on the "obesity epidemic" - and, by extension, on public health crises commonly blamed on personal behavior - may unintentionally activate prejudice.

    Background Health behaviours, important factors in cardiovascular disease, are increasingly a focus of prevention. We appraised whether stroke risk can be accurately assessed using self-reported information focused on health behaviours. Methods Behavioural, sociodemographic and other risk factors were assessed in a population-based survey of 82 259 Ontarians who were followed for a median of 8.6 years (688 000 person-years follow-up) starting in 2001. Predictive algorithms for 5-year incident stroke resulting in hospitalization were created and then validated in a similar 2007 survey of 28 605 respondents (median 4.2 years follow-up). Results We observed 3 236 incident stroke events (1 551 resulting in hospitalization; 1 685 in the community setting without hospital admission). The final algorithms were discriminating (C-stat: 0.85, men; 0.87, women) and well-calibrated (in 65 of 67 subgroups for men; 61 of 65 for women). An index was developed to summarize cumulative relative risk of incident stroke from health behaviours and stress. For men, each point on the index corresponded to a 12% relative risk increase (180% risk difference, lowest (0) to highest (9) scores). For women, each point corresponded to a 14% relative risk increase (340% difference, lowest (0) to highest (11) scores). Algorithms for secondary stroke outcomes (stroke resulting in death; classified as ischemic; excluding transient ischemic attack; and in the community setting) had similar health behaviour risk hazards. Conclusion Incident stroke can be accurately predicted using self-reported information focused on health behaviours. Risk assessment can be performed with population health surveys to support population health planning or outside of clinical settings to support patient-focused prevention. PMID:26637172

    This study employed an independent-groups design (4 conditions) to investigate possible biases in the suicide risk perception of mental health professionals. Four hundred participants comprising doctors, nurses and social workers viewed a vignette describing a fictitious patient with a long-term mental illness. The case was presented as being drawn from a sample of twenty similar clinical case reports, of which 10 were associated with an outcome of suicide. The participant tasks were (i) to decide whether the presented vignette was one of those cases or not, and (ii) to provide an assessment of confidence in that decision. The 4 conditions were used to investigate whether the presence of an associated face, and the nature of the emotional state expressed by that face, affected the response profile. In fact, there were no significant differences between conditions, but there was a significant bias across all conditions towards associating the vignette with suicide, despite the base rate being pre-determined at 50%. The bias was more pronounced in doctors and in male respondents. Moreover, many participants indicated substantial confidence in their decisions. The results are discussed in terms of availability bias and over-confidence bias. PMID:26909886

  13. Health benefits and risk associated with adopting a vegetarian diet.

    A vegetarian diet may be adopted for various reasons that can include ecological, economic, religious, ethical and health considerations. In the latter case they arise from the desire to lose weight, in tackling obesity, improving physical fitness and/or in reducing the risk of acquiring certain diseases. It has been shown that properly applied vegetarian diet is the most effective way of reducing body mass (expressed as BMI), improving the plasma lipid profile and in decreasing the incidence of high arterial blood pressure, cardiovascular disease, stroke, metabolic syndrome and arteriosclerosis. In addition, improved insulin sensitivity together with lower rates of diabetes and cancer has been observed. Some studies have however found that a vegetarian diet may result in changes adversely affecting the body. These could include; hyperhomocysteinaemia, protein deficiency, anaemia, decreased creatinine content in muscles and menstrual disruption in women who undertake increased physical activity. Some of these changes may decrease the ability for performing activities that require physical effort. Nevertheless, on balance it can be reasonably concluded that the beneficial effects of a vegetarian diet significantly, by far, outweigh the adverse ones. It should also be noted that the term 'vegetarian diet' is not always clearly defined in the literature and it may include many dietary variations. PMID:24964573

    The aim of this article consists of developing an ecosystemic approach to collect information about groundwater pollution in order to determine its origin and infer the health risks in Mingoa's watershed through the study of 12 spontaneous settlements. From an environmental point of view, family interviews and direct observations allowed us to inventory springs, wells and latrines, and to collect information. So, we have selected, on the basis of predefined criteria, 21 wells and springs for physico-chemical and bacteriological laboratory analyses. Two hundred children aged less than 5 years were subjected to KOAP examination. A number of 1224 latrines were inventoried, for an average use of 15 people per latrine, producing 913.3 kg/year of excreta. Most of 91% of people use these latrines. The superficial aquifers, connected to the wells and springs, present high values of nitrogen, phosphorous pollutant and fecal contamination indicators (coliforms and fecal streptococcus), which make water inappropriate to human consumption. PCA analysis establishes that water pollution comes mainly from traditional pit latrines. The overall prevalence of diarrhea and parasite infestation was important (=40%). The presence of cysts of Entamoeba histolytica, Ascaris limbricoides, and Entamoeba coli confirms this high prevalence and testify to very approximate hygiene and environment conditions.

    There is presented the analysis of medical-demographic situation in Russia, and the increase in population mortality is shown both to be associated with the degradation of the geosphere and alongside with other factors determined by the change in the electronic state of the environment. On the base of the interrelationship between the electronic saturation of the environment and an increase in population mortality and morbidity there is established a such risk factor for human health and life, which may currently become one out of significant, videlicet, the electronic deficit. In conditions of its appearance there are proposed options solving this problem by means of elaboration of the scientific rationale for the impact of the electronic deficit on the human organism and the creation of technologies providing environmental--medical safety of the population by virtue of the correction of the electronic state of the human habitat, food and drinking water and the implementation of the system for monitoring electronic abundance of the environment.

    Socio-economic differences in risk behaviors in adolescence can be seen as a prelude to the re-emergence of socio economic health differences in adulthood. We studied whether or not socio-economic differences in health risk behaviors are present in male and female adolescents in The Netherlands. The relation between socio-economic status (SES) and health risk behaviors was examined, by testing both the main and interaction effects of SES and gender on separate health risk behaviors on one hand, and on the behaviors cumulatively on the other. The data were derived from 1984 adolescents in the four northern provinces of The Netherlands. SES was measured by means of the educational level and the occupational status of both parents. Four health risk behaviors were included in this study: smoking, alcohol consumption, soft drug use, and (no) physical exercise. We found that the relationships between SES and health risk behaviors are not as linear as is often found in adulthood. Our findings can be characterised overall by an absence of relationship between SES and health risk behaviors. The only exception applies to sport, which is linearly related to SES. Adolescents in the lower SES groups engage in sport less than adolescents in the higher SES groups. There was an irregular relationship between the father's occupational status and the adolescents' smoking and drinking. Adolescents in the highest, lowest and middle of the six SES groups have the highest rates of health risk behaviors. All observed relationships are similar for both male and female adolescents. A relationship between gender and the separate health risk behaviors was found only for alcohol consumption and drug use. For both male adolescents showed higher rates of risk behavior. Males also scored higher on the cumulative health risk behaviors than their female counterparts. The findings of this study do not support the hypothesis of latent differences in adolescence.

    The increase of healthcare facilities in Shinyanga municipality has resulted in an increase of healthcare wastes, which poses serious threats to the environment, health workers, and the general public. This research was conducted to investigate management practices of healthcare wastes in Shinyanga municipality with a view of assessing health risks to health workers and the general public. The study, which was carried out in three hospitals, involved the use of questionnaires, in-depth interview, and observation checklist. The results revealed that healthcare wastes are not quantified or segregated in all the three hospitals. Healthcare wastes at the Shinyanga Regional Referral Hospital are disposed of by on-site incineration and burning and some wastes are disposed off-site. At Kolandoto DDH only on-site burning and land disposal are practiced, while at Kambarage UHC healthcare solid wastes are incinerated, disposed of on land disposal, and burned. Waste management workers do not have formal training in waste management techniques and the hospital administrations pay very little attention to appropriate management of healthcare wastes. In light of this, it is evident that management of healthcare solid wastes is not practiced in accordance with the national and WHO's recommended standards. PMID:26779565

    Knowledge about differences in consumer perceptions of health risks and benefits related to fish consumption is important for the development of targeted health interventions associated with dietary choice. The purpose of this study is to identify individual differences in Russian consumers according to their perceptions of health risks and benefits associated with fish consumption. By application of a cluster analysis on perceptions of personal risks and benefits associated with the consumption of fish, four groups of Russian consumers were classified as: very positive; positive; moderately positive; and 'high risk-high benefit' about the healthiness of fish consumption. Differences in perceptions of personal risks and benefits across consumers were related to self-reported fish consumption, optimism about personal risks and benefits, and optimism about personal knowledge about risks and benefits. Implications for the development of targeted health interventions to influence perceptions of risks and benefits associated with fish consumption, and ultimately fish consumption, are discussed. It is concluded that optimism regarding perceptions and knowledge of health risks, and health benefits should be taken into account when developing interventions aimed at consumer health.

    We explore whether the health risks related to air pollution and temperature extremes are spatially and socioeconomically differentiated within three Latin American cities: Bogota, Colombia, Mexico City, Mexico, and Santiago, Chile. Based on a theoretical review of three relevant approaches to risk analysis (risk society, environmental justice, and urban vulnerability as impact), we hypothesize that health risks from exposure to air pollution and temperature in these cities do not necessarily depend on socio-economic inequalities. To test this hypothesis, we gathered, validated, and analyzed temperature, air pollution, mortality and socioeconomic vulnerability data from the three study cities. Our results show the association between air pollution levels and socioeconomic vulnerabilities did not always correlate within the study cities. Furthermore, the spatial differences in socioeconomic vulnerabilities within cities do not necessarily correspond with the spatial distribution of health impacts. The present study improves our understanding of the multifaceted nature of health risks and vulnerabilities associated with global environmental change. The findings suggest that health risks from atmospheric conditions and pollutants exist without boundaries or social distinctions, even exhibiting characteristics of a boomerang effect (i.e., affecting rich and poor alike) on a smaller scale such as areas within urban regions. We used human mortality, a severe impact, to measure health risks from air pollution and extreme temperatures. Public health data of better quality (e.g., morbidity, hospital visits) are needed for future research to advance our understanding of the nature of health risks related to climate hazards.

    1998-11-10

    Version: 00 CRRIS consists of eight fully integrated computer codes which calculate environmental transport of atmospheric releases of radionuclides and resulting doses and health risks to individuals or populations. Each code may be used alone for various assessment applications. Because of its modular structure, CRRIS allows assessments to be tailored to the user's needs. Radionuclides are handled by CRRIS either in terms of the released radionuclides or the exposure radionuclides which consist of both the released nuclides and decay products that build up during environmental transport. Atmospheric dispersion calculations are performed by the ANEMOS computer code for distances less than 100 km and by the RETADD-II computer code for regional-scale distances. Both codes estimate annual-average air concentrations and ground deposition rates by location. SUMIT will translate and scale multiple ANEMOS runs onto a master grid. TERRA reads radionuclide air concentrations and deposition rates to estimate concentrations of radionuclides in food and surface soil. Radiologic decay and ingrowth, soil leaching, and transport through the food chain are included in the calculations. MLSOIL computes an effective radionuclide ground-surface concentration to be used in computing external health effects. The five-layer model of radionuclide transport through soil in MLSOIL provides an alternative to the single-layer model used in TERRA. DFSOIL computes dose factors used in MLSOIL to compute doses from the five soil layers and from the ground surface. ANDROS reads environmental concentrations of radionuclides computed by the other CRRIS codes and produces tables of doses and risks to individuals or populations from atmospheric releases of radionuclides.

    Liang, Ching-Ping; Wang, Shen-Wei

    2014-05-01

    Groundwater has been massively used for drinking by local residents due to deficiency in surface water in Pingtung Plain, Taiwan. A long-term survey of groundwater quality revealed that concentrations of water quality items in some of the monitoring wells exceeded the Taiwanese standards for drinking water quality. Water of poor quality can have an adverse health impact. Effective health risk-based groundwater management typically faces great challenges because of the inherent spatial variability in groundwater quality. In this study, we target to spatially analyze the health hazard and risk from consumption of groundwater for drinking. We computed the hazard quotient and health risk using exposure and risk model and hydrochemical data surveyed by Taiwan Water Resource Agency and Environmental Protection Agency. The zone suitable for groundwater used is delineated based on the results of the spatial health risk map. The results of the analysis can help government administrator in managing groundwater used for drinking in Pingtung Plain in Taiwan.

    2012-01-01

    Background Increased availability of genetic risk information may lead the public to give precedence to genetic causation over behavioral/environmental factors, decreasing behavior change motivation. Few population-based data inform these concerns. Purpose We assess the association of family history, behavioral risks, and causal attributions for diseases and the perceived value of pursuing information emphasizing health habits or genes. Method 1959 healthy adults completed a survey that assessed behavioral risk factors, family history, causal attributions of eight diseases, and health information preferences. Results Participants’ causal beliefs favored health behaviors over genetics. Interest in behavioral information was higher than in genetic information. As behavioral risk factors increased, inclination toward genetic explanations increased; interest in how health habits affect disease risk decreased. Conclusions Those at greatest need for behavior change may hold attributions that diminish interest in behavior change information. Enhancing understanding of gene-environment influences could be explored to increase engagement with health information. PMID:20532842

    Return on investment (ROI) is an economic measure used to indicate how much economic benefit is derived from a program in relation to its costs. Interest in the use of ROI in public health has grown substantially over recent years. Given its potential influence on resource allocation, it is crucial to understand the benefits and the risks of using ROI to defend public health programs. In this paper, we explore those benefits and risks. We present two recent examples of ROI use in public health in the United States and Canada and conclude with a series of proposals to minimize the risks associated with using ROI to defend public health interventions.

    1992-01-01

    In order to develop plausible and appropriate drinking water contaminant standards for longer-term NASA space missions, such as those planned for the Space Exploration Initiative, a human health risk characterization was performed using toxicological and exposure values typical of space operations and crew. This risk characterization showed that the greatest acute waterborne health concern was from microbial infection leading to incapacitating gastrointestinal illness. Ingestion exposure pathways for toxic materials yielded de minimus acute health risks unlikely to affect SEI space missions. Risks of chronic health problems were within acceptable public health limits. Our analysis indicates that current Space Station Freedom maximum contamination levels may be unnecessarily strict. We propose alternative environmental contaminant values consistent with both acceptable short and long-term crew health safety.

    Unexpected medical care spending imposes considerable financial risk on developing country households. Based on managed care models of health insurance in wealthy countries, Colombia’s Régimen Subsidiado is a publicly financed insurance program targeted to the poor, aiming both to provide risk protection and to promote allocative efficiency in the use of medical care. Using a “fuzzy” regression discontinuity design, we find that the program has shielded the poor from some financial risk while increasing the use of traditionally under-utilized preventive services – with measurable health gains.

    Climate change is already taking a toll on human health, a toll that is likely to increase in coming decades. The relationship between risk perceptions and vulnerability to climate change’s health threats has received little attention, even though an understanding of the dynamics of adaptation among particularly susceptible populations is becoming increasingly important. We demonstrate that some people whose health will suffer the greatest harms from climate change—due to social vulnerability, health susceptibility, and exposure to hazards—already feel they are at risk. In a 2013 survey we measured Maryland residents’ climate beliefs, health risk perceptions, and household social vulnerability characteristics, including medical conditions (n = 2126). We paired survey responses with secondary data sources for residence in a floodplain and/or urban heat island to predict perceptions of personal and household climate health risk. General health risk perceptions, political ideology, and climate beliefs are the strongest predictors. Yet, people in households with the following characteristics also see themselves at higher risk: members with one or more medical conditions or disabilities; low income; racial/ethnic minorities; and residence in a floodplain. In light of these results, climate health communication among vulnerable populations should emphasize protective actions instead of risk messages. PMID:26690184

The data was collected and analyzed on SPSS version 20. Results: During these study period 51 women needed ICU care for different complications due to adverse effects of medical treatments. Majority of these women were between 20-40 years of age 41(80.39%), multiparous 29(56.86%), unbooked 38(74.50%), referred from periphery 39(76.47%), common iatrogenic factors were misuse of oxytocin 16(31.37%), fluid overload/cardiac failure 8(15.68%), blood reaction 7(13.72%), anesthesia related problems were delayed recovery 3(5.88%), cardiac arrest 2(3.92%), spinal shock 2(3.92%), surgical problems were bladder injury 5(9.8%), post operative internal haemorrhage 3(5.88%), 37(72.54%) women recovered and 14(27.45%) expired. Conclusion: The maternal morbidity and mortality rate with iatrogenic factors was high and majority of these factors were avoidable. PMID:24639842

  8. Nanotechnology, cosmetics and the skin: is there a health risk?

    Cosmetic formulations may contain nano-emulsions and microscopic vesicles consisting of traditional cosmetic materials, although it is uncertain whether they should be qualified as actual nanomaterials. Vesicle materials do not penetrate into living human skin. Vesicle formulations may enhance or reduce skin absorption of ingredients, albeit at a limited scale. Sunscreens contain TiO2 or ZnO nanoparticles (NP), which are efficient UV filters. A number of studies suggest that insoluble NP do not penetrate into or through human skin. The results of in vivo toxicity tests showed that TiO2 and ZnO NP are non-toxic. In vitro and in vivo cytotoxicity, genotoxicity, photogenotoxicity, acute toxicity, sensitisation and ecotoxicology studies on TiO2 NP found no difference in the safety profile of micro- or nano-sized materials, all of which were non-toxic. Although some in vitro investigations on TiO2 particles reported cell uptake, oxidative cell damage or genotoxicity, these results may be secondary to phagocytosis of cells exposed to excessive particle concentrations. Studies on wear debris nano- and microparticles support the traditional view that toxicity of small particles is related to their chemistry, rather than their particle size. There is little evidence supporting a general rule that adverse effects of particles on the skin or other tissues increase with smaller particle size, or produce novel toxicities relative to those of larger particles. Overall, the current evidence suggests that nano-sized cosmetic or sunscreen ingredients pose no potential risk to human health, whereas their use in sunscreens has large benefits, such as the protection of human skin against skin cancer.

    As human-driven climate change advances, many adults fret about the losses of livelihoods, houses and farms that may result. Children fret about their parents' worries and about information they hear, but do not really understand about the world's climate and perhaps about their own futures. In chronically worried or anxious children, blood cortisol levels rise and adverse changes accrue in various organ systems that prefigure adult-life diseases. Meanwhile, for many millions of children in poor countries who hear little news and live with day-to-day fatalism, climate change threatens the fundamentals of life-food sufficiency, safe drinking water and physical security-and heightens the risks of diarrhoeal disease, malaria and other climate-sensitive infections. Poor and disadvantaged populations, and especially their children, will bear the brunt of climate-related trauma, disease and premature death over the next few decades and, less directly, from social disruption, impoverishment and displacement. The recent droughts in Somalia as the Indian Ocean warmed and monsoonal rains failed, on top of chronic civil war, forced hundreds of thousands of Somali families into north-eastern Kenya's vast Dadaab refugee camps, where, for children, shortages of food, water, hygiene and schooling has endangered physical, emotional and mental health. Children warrant special concern, both as children per se and as the coming generation likely to face ever more extreme climate conditions later this century. As children, they face diverse risks, from violent weather, proliferating aeroallergens, heat extremes and mobilised microbes, through to reduced recreational facilities, chronic anxieties about the future and health hazards of displacement and local resource conflict. Many will come to regard their parents' generation and complacency as culpable. PMID:27417469

    1989-06-01

    A telephone survey was completed with 400 adults to explore a possible relation between health risk-taking and perceived personal responsibility for health. The attitude that AIDS could be avoided by being careful was weakly associated with responses to questions about wearing seat belts and smoking. The pattern held only among those who thought their health was good for people their age. After reviewing related literature, it appears that poor health status and dogmatism may contribute to denial of risk and to risky sexual behavior. Themes for public health educational campaigns are suggested. PMID:2762466

    Health information exchange (HIE) is a significant component of healthcare transformation strategies at both the state and national levels. HIE is expected to improve care coordination, and advance public health, but implementation is massively complex and involves significant risk. In New York, three regional health information organizations (RHIOs) implemented an HIE use case for public health reporting by demonstrating capability to deliver accurate responses to electronic queries via a set of services called the Universal Public Health Node. We investigated process and outcomes of the implementation with a comparative case study. Qualitative analysis was structured around a decision and risk matrix. Although each RHIO had a unique operational model, two common factors influenced risk management and implementation success: leadership capable of agile decision-making and commitment to a strong organizational vision. While all three RHIOs achieved certification for the public health reporting, only one has elected to deploy a production version. PMID:23975626

    Objective This study aimed at investigating whether cardiovascular risk factors and their impact on total risk estimation differ between men and women. Design Cross-sectional cohort study. Subjects Finnish cardiovascular risk subjects (n = 904) without established cardiovascular disease, renal disease, or known diabetes. Main outcome measures Ankle-brachial index (ABI), estimated glomerular filtration rate (eGFR), oral glucose tolerance test, and total cardiovascular risk using SCORE risk charts. Results According to the SCORE risk charts, 27.0% (95% CI 23.1–31.2) of the women and 63.1% (95% CI 58.3–67.7) of the men (p < 0.001) were classified as high-risk subjects. Of the women classified as low-risk subjects according to SCORE, 25% had either subclinical peripheral arterial disease or renal insufficiency. Conclusions The SCORE system does not take into account cardiovascular risk factors typical in women, and thus underestimates their total cardiovascular risk. Measurement of ABI and eGFR in primary care might improve cardiovascular risk assessment. especially in women. PMID:22643155

    Harmful cyanobacterial blooms have adversely impacted human and animal health for thousands of years. Recently, the health impacts of harmful cyanobacteria blooms are becoming more frequently detected and reported. However, reports of human and animal illnesses or deaths associated with harmful cyanobacteria blooms tend to be investigated and reported separately. Consequently, professionals working in human or in animal health do not always communicate findings related to these events with one another. Using the One Health concept of integration and collaboration among health disciplines, we systematically review the existing literature to discover where harmful cyanobacteria-associated animal illnesses and deaths have served as sentinel events to warn of potential human health risks. We find that illnesses or deaths among livestock, dogs and fish are all potentially useful as sentinel events for the presence of harmful cyanobacteria that may impact human health. We also describe ways to enhance the value of reports of cyanobacteria-associated illnesses and deaths in animals to protect human health. Efficient monitoring of environmental and animal health in a One Health collaborative framework can provide vital warnings of cyanobacteria-associated human health risks. PMID:25903764

    PURPOSE OF THE REVIEW. The purpose of this review is to assist those who work in the field of health promotion when considering the implementation of an individually risk-rated health insurance plan. It does so by introducing the reader to the concept of individually risk-rating health insurance; uncritically reviewing selected risk-rated health insurance plans; and exploring several issues related to plan implementation, administration, and appropriateness. SEARCH METHODS USED. The review is based on the authors' awareness of the literature in the fields of preventive medicine, health promotion, and employee benefits. The six individually risk-rated health insurance programs that are reviewed were chosen because they demonstrate how aspects of the National Association of Insurance Commissioners' Model have been implemented using various combinations of administrative procedures, verification strategies, and types of economic incentives or disincentives. This review is not intended to be a comprehensive review of the literature. SUMMARY OF IMPORTANT FINDINGS. Individually risk-rated health insurance programs have been established using a variety of administrative procedures, verification strategies, and types of economic incentives or disincentives. The frequency with which these programs are being established is increasing. As the number of risk-rated programs grows, it will be increasingly important to address the many issues that implementing such plans generate: How should lifestyle behaviors be verified? Will healthy lifestyles save money? Can employees fully control their risk factors? Is risk-rating socially responsible? MAJOR CONCLUSIONS. As risk-rating becomes more widespread, there will be a continuing need to address the business, medical, ethical, and legal issues these programs create and to refine them accordingly. The health promotion community has both an opportunity and obligation to see to it that individually risk-rated health insurance programs

    The present survey was designed to investigate the perception of health risks among college students in China. The data are the responses of a sample of 3,069 college students at one university to surveys that include measures of several dimensions of public judgments about fifteen specific hazards. Chinese college students conveyed their concerns as falling into three broad categories: Environmental (e.g., global warming, natural catastrophes, the ozone hole, air pollution, chemical pollution, pesticides in food), Technological (e.g., nuclear power stations, thermal power, genetically modified food, medical X-rays), and Social (cigarette smoking, drinking alcohol, overtime study or work, mental stress, motor vehicle accidents). The data were collected with a self-report questionnaire. Descriptive statistics were used to illustrate the levels of perceived risk according to the percent of “high risk” responses as well as the mean response values. Generally, the hazards that were perceived as posing the greatest health risk were those belonging to the social health risks; items related to technology risks received the lowest percentage of “high health risk” rankings. Traditional environmental risks such as natural catastrophes, pollution issues (chemical pollution, air pollution), and pesticides in food were ranked as being relatively high risks. The respondents were less concerned about new emerging issues and long-term environmental risks (global warming). In this survey, motor vehicle accidents were considered to be a “high health risk” by the greatest percentage of respondents. Generally speaking, the female respondents’ degree of recognition of health risks is higher than that of male respondents. Only for the item of smoking was the male respondents’ degree higher than that of females. There is also a geographic imbalance in the health risk perceptions. The degree of recognition of health risks from respondents in municipalities is generally

    1993-12-01

    The importance of risk communication and participation in the solution of environmental health problems has been increasingly appreciated. However, realisation is a demanding task for health departments, as practical experience is limited. Psychological processes in risk perception facilitate confounding of different levels of conflict. Therefore, risk communication and participation should be organised as a stepwise procedure which separates risk assessment, risk evaluation and risk management options. The present paper discusses problems which might emerge in each of these issues and suggests possible solutions. Risk communication aims at implementation of transparent decision making processes involving citizens. However, even when agreement in risk assessment can be achieved, arriving at a consensus in respect of decision making might fail if facts are weighted differently. PMID:8111158

    Efforts at improving child-health and development initiatives in sub-Saharan Africa had focused on the physical health of children due to the neglect of child and adolescent mental health (CAMH) policy initiatives. A thorough and broad-based understanding of the prevalent child mental-health risk and vulnerability factors is needed to successfully articulate CAMH policies. In this discourse, we present a narrative on the child mental-health risk and vulnerability factors in sub-Saharan Africa. Through an ecological point of view, we identified widespread family poverty, poor availability and uptake of childcare resources, inadequate community and institutional childcare systems, and inadequate framework for social protection for vulnerable children as among the risk and vulnerability factors for CAMH in the region. Others are poor workplace policy/practice that does not support work-family life balance, poor legislative framework for child protection, and some harmful traditional practices. We conclude that an ecological approach shows that child mental-health risks are diverse and cut across different layers of the care environment. The approach also provides a broad and holistic template from which appropriate CAMH policy direction in sub-Saharan Africa can be understood. PMID:24834431

    The number of older drivers will continue to increase as the population ages. Health care professionals have the responsibility of providing care and maintaining confidentiality for their patients while ensuring public safety. This article discusses the ethics of clinical decision-making pertaining to reporting health-related driving risk of older drivers to licensing authorities. Ethical considerations inherent in reporting driving risk, including autonomy, confidentiality, therapeutic relationships, and the uncertainty about determining individual driving safety and risk, are discussed. We also address the moral agency of reporting health-related driving risk and raise the question of whose responsibility it is to report. Issues of uncertainty surrounding clinical reasoning and concepts related to risk assessment are also discussed. Finally, we present two case studies to illustrate some of the issues and challenges faced by health care professionals as they seek to balance their responsibilities for their patients while ensuring road safety for all citizens.

    The epidemiological dimension of mental health problems in childhood and its impact warrant new studies. Knowledge about the predictors of mental health in children is scant in developing countries. The present study estimated the prevalence of psychiatric disorders in Brazilian school-age children based on a community sample from primary health care services, with the aim of verifying the predictive value of biological, social, and familial risk factors in children's mental health. The study was performed with 120 children of both genders identified through their mothers. The children's mental health was evaluated by sociodemographic factors and a diagnostic interview conducted with parents. Biological, social, and familial risk factors were evaluated by the Supplemental Questionnaire and Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, 4th edition. Of the 120 children, 45.8 % were diagnosed with at least one mental health disorder. Children with diagnoses of depressive disorder and generalized anxiety disorder presented evidence of greater exposure to risk factors compared with children without these psychiatric diagnoses. Children with more risk factors throughout their lifetime had greater comorbidities compared with children with a lower number of risk factors. The identification of groups exposed to interconnected risk factors represents a priority when planning mental health practices. The strong role of chronic familial risk factors needs to be emphasized because they are a possible target for the prevention of depressive and anxiety disorders. PMID:23212399

    We present a probabilistic framework to addressing adverse human health effects due to groundwater contamination. One of the main challenges in health risk assessment is in relating it to subsurface data acquisition and to improvement in our understanding of human physiological responses to contamination. In this paper we propose to investigate this problem through an approach that integrates flow, transport and human health risk models with hydrogeological characterization. A human health risk cumulative distribution function is analytically developed to account for both uncertainty and variability in hydrogeological as well as human physiological parameters. With our proposed approach, we investigate under which conditions the reduction of uncertainties from flow physics, human physiology and exposure related parameters might contribute to a better understanding of human health risk assessment. Results indicate that the human health risk cumulative distribution function is sensitive to physiological parameters at low risk values associated with longer travel times. The results show that the worth of hydrogeological characterization in human health risk is dependent on the residence time of the contaminant plume in the aquifer and on the exposure duration of the population to certain chemicals.

    There is a growing awareness and concern in contemporary societies about potential health impacts of environmental contaminants on children. Mothers are traditionally more involved than other family members in managing family health and household decisions and thus targeted by public health campaigns to minimise risks. However little is known about how new mothers perceive and experience environmental health risks to their children. In 2010, we undertook a parallel case study using qualitative, in-depth interviews with new mothers and focus groups with public health key informants in two Public Health Units in Ontario Province, Canada. We found that the concern about environmental hazards among participants ranged from having no concerns to actively incorporating prevention into daily life. Overall, there was a common perception among participants that many risks, particularly in the indoor environment, were controllable and therefore of little concern. But environmental risks that originate outside the home were viewed as less controllable and more threatening. In response to such threats, mothers invoked coping strategies such as relying on the capacity of children's bodies to adapt. Regardless of the strategies adopted, actions (or inactions) were contingent upon active information seeking. We also found an optimistic bias in which new mothers reported that other children were at greater risk despite similar environmental circumstances. The findings suggest that risk communication experts must attend to the social and environmental contexts of risk and coping when designing strategies around risk reducing behaviours. PMID:23805055

    Risk for adult mental health problems associated with child sexual, physical, or emotional abuse and multiple types of child abuse was examined. Logistic regression analyses were used to test study hypotheses in a population-based sample of women (N = 3,936). As expected, child sexual, physical, and emotional abuse were independently associated with increased risk for mental health problems. History of multiple types of child abuse was also associated with elevated risk for mental health problems. In particular, exposure to all three types of child abuse was linked to a 23-fold increase in risk for probable posttraumatic stress disorder (PTSD). Findings underscore relations between child emotional abuse and adult mental health problems and highlight the need for mental health services for survivors of multiple types of child abuse.

    Since health-risk behaviors are often encountered in clusters among adolescents, it was hypothesized that adolescents with poor school attendance would be associated with more health-risk behaviors (e.g., substance use, violence) than those who attend school regularly. This study assessed the relationship between poor school attendance and health-risk behaviors, and described health-risk behaviors and self-esteem among adolescents seeking employment. In this cross-sectional study, school attendance (poor vs. regular attendance) was related to health-risk behaviors by asking 122 subjects seen at a New York City Working Papers Clinic to complete both a 72-item questionnaire about their health-risk behaviors and the 58-item Coopersmith Self-Esteem School Form Inventory. Chi-square and Fisher's Exact Tests were performed. The poor and regular attenders of school differed significantly in only 5 out of 44 items pertaining to health-risk behaviors. Self-esteem measures for the two groups did not differ from one another or from national norms. In this sample, depression "in general" (global) and "at home," but not "at school," were associated significantly with suicidal thoughts/attempts and serious past life events (e.g. family conflict, sexual abuse). There were no significant associations between depression or self-esteem and illicit substance or alcohol use. We found few associations between poor school attendance and health-risk behaviors in this sample of employment-seeking adolescents. The poor and regular attenders of school were similar in most aspects of their health-risk behaviors and self-esteem. PMID:8982520

    Studies of fish consumption often focus on awareness of and adherence to advisories, how much fish people eat, and contaminant levels in those fish. This paper examines knowledge and accuracy of risks and benefits of fish consumption among fishers and other recreationists in the New York Bight, indicative of whether they could make sound dietary decisions. While most respondents knew about health risks (70%) and benefits (94%) of consuming fish, far fewer could name specific risks and benefits. Less than 25% of respondents mentioned mercury and less than 15% mentioned that pregnant women and children were at risk. Far fewer people mentioned polychlorinated biphenyls (PCBs). Nearly 70% said it was healthy to eat fish, and 45% were aware that fish were rich in healthful oils. Despite the lack of details about what specific risks and benefits of fish, well over a third did not feel they needed more information. Other respondents had basic questions, but did not pose specific questions about the fish they caught or ate that would have clarified their individual risk-balancing decisions. Knowledge of which fish were high in contaminants did not match the mercury or PCB levels in those fish. There was a disconnect between the information base about specific risks and benefits of fish consumption, levels of mercury and PCBs in fish, and the respondent’s desire for more information. These data indicate that respondents did not have enough accurate information about contaminants in fish to make informed risk-balancing decisions. PMID:19193369

  9. Are endocrine disrupting compounds a health risk in drinking water?

    PubMed

    Falconer, Ian R

    2006-06-01

    There has been a great deal of international discussion on the nature and relevance of endocrine disrupting compounds in the environment. Changes in reproductive organs of fish and mollusks have been demonstrated in rivers downstream of sewage discharges in Europe and in North America, which have been attributed to estrogenic compounds in the effluent. The anatomical and physiological changes in the fauna are illustrated by feminization of male gonads. The compounds of greatest hormonal activity in sewage effluent are the natural estrogens 17Beta-estradiol, estrone, estriol and the synthetic estrogen ethinylestradiol. Androgens are also widely present in wastewaters. Investigations of anthropogenic chemical contaminants in freshwaters and wastewaters have shown a wide variety of organic compounds, many of which have low levels of estrogenic activity. In many highly populated countries the drinking water is sourced from the same rivers and lakes that are the recipients of sewage and industrial discharge. The River Thames which flows through London, England, has overall passed through drinking water and sewage discharge 5 times from source to mouth of the river. Under these types of circumstance, any accumulation of endocrine disrupting compounds from sewage or industry potentially affects the quality of drinking water. Neither basic wastewater treatment nor basic drinking water treatment will eliminate the estrogens, androgens or detergent breakdown products from water, due to the chemical stability of the structures. Hence a potential risk to health exists; however present data indicate that estrogenic contamination of drinking water is very unlikely to result in physiologically detectable effects in consumers. Pesticide, detergent and industrial contamination remain issues of concern. As a result of this concern, increased attention is being given to enhanced wastewater treatment in locations where the effluent is directly or indirectly in use for drinking water

    Carbon dioxide (CO2) is an anthropogenic gas that accumulates in spacecraft to much higher levels than earth-normal levels. Controlling concentrations of this gas to acceptable levels to ensure crew health and optimal performance demands major commitment of resources. NASA has many decades of experience monitoring and controlling CO2, yet we are uncertain of the levels at which subtle performance decrements develop. There is limited evidence from ground-based studies that visual disturbances can occur during brief exposures and visual changes have been noted in spaceflight crews. These changes may be due to CO2 alone or in combination with other known spaceflight factors such as increased intracranial pressure due to fluid shifts. Discerning the comparative contribution of each to performance decrements is an urgent issue if we hope to optimize astronaut performance aboard the ISS. Long-term, we must know the appropriate control levels for exploration-class missions to ensure that crewmembers can remain cooperative and productive in a highly stressful environment. Furthermore, we must know the magnitude of interindividual variability in susceptibility to the adverse effects of CO2 so that the most tolerant crewmembers can be identified. Ground-based studies have been conducted for many years to set exposure limits for submariners; however, these studies are typically limited and incompletely reported. Nonetheless, NASA, in cooperation with the National Research Council, has set exposure limits for astronauts using this limited database. These studies do not consider the interactions of spaceflight-induced fluid shifts and CO2 exposures. In an attempt to discern whether CO2 levels affect the incidence of headache and visual disturbances in astronauts we performed a retrospective study comparing average CO2 levels and the prevalence of headache and visual disturbances. Our goal is to narrow gaps in the risk profile for in-flight CO2 exposures. Such studies can

    Increasing consumption of pharmaceuticals leads also to higher release of its non-metabolized residues into environment, mostly hydrosphere. Some of these substances may reach also processed drinking water. Although it is found in traces, it causes public concern as it can represent a non-targeted and unwanted medication. Toxicologists and public health authorities are appealed to assess potential health risks carefully and to communicate the risk adequately to public. As health risks assessment of environmental exposure to pharmaceuticals is a new field of expertise, its methodology has not been unified and standardized yet, but several different procedures have been proposed and used. The paper provides overview of these methods. PMID:22442888

    Buffalo River is an important water resource in the Eastern Cape Province of South Africa. The potential risks of infection constituted by exposure to human enteric viruses in the Buffalo River and three source water dams along its course were assessed using mean values and static quantitative microbial risk assessment (QMRA). The daily risks of infection determined by the exponential model [for human adenovirus (HAdV) and enterovirus (EnV)] and the beta-Poisson model (for hepatitis A virus (HAV) and rotavirus (RoV)) varied with sites and exposure scenario. The estimated daily risks of infection values at the sites where the respective viruses were detected, ranged from 7.31 × 10(-3) to 1 (for HAdV), 4.23 × 10(-2) to 6.54 × 10(-1) (RoV), 2.32 × 10(-4) to 1.73 × 10(-1) (HAV) and 1.32 × 10(-4) to 5.70 × 10(-2) (EnV). The yearly risks of infection in individuals exposed to the river/dam water via drinking, recreational, domestic or irrigational activities were unacceptably high, exceeding the acceptable risk of 0.01% (10(-4) infection/person/year), and the guideline value used as by several nations for drinking water. The risks of illness and death from infection ranged from 6.58 × 10(-5) to 5.0 × 10(-1) and 6.58 × 10(-9) to 5.0 × 10(-5), respectively. The threats here are heightened by the high mortality rates for HAV, and its endemicity in South Africa. Therefore, we conclude that the Buffalo River and its source water dams are a public health hazard. The QMRA presented here is the first of its kinds in the Eastern Cape Province and provides the building block for a quantitatively oriented local guideline for water quality management in the Province.

    Heart disease is the leading cause of death worldwide. Therefore, assessing the risk of its occurrence is a crucial step in predicting serious cardiac events. Identifying heart disease risk factors and tracking their progression is a preliminary step in heart disease risk assessment. A large number of studies have reported the use of risk factor data collected prospectively. Electronic health record systems are a great resource of the required risk factor data. Unfortunately, most of the valuable information on risk factor data is buried in the form of unstructured clinical notes in electronic health records. In this study, we present an information extraction system to extract related information on heart disease risk factors from unstructured clinical notes using a hybrid approach. The hybrid approach employs both machine learning and rule-based clinical text mining techniques. The developed system achieved an overall microaveraged F-score of 0.8302. PMID:26380290

    A structured psychosocial risk screening interview, the Prenatal Risk Overview, was administered to 733 women in prenatal care. Either a community health worker (CHW) or a registered nurse (RN) conducted the interview based on day of the week. A comparison of identified risk factors found no significant differences between study samples for six of 13 domains. For CHW interviews, significantly more participants were classified as Moderate/ High Risk for Depression, Lack of Telephone Access, Food Insecurity, and Housing Instability, and as High Risk for Lack of Social Support, Lack of Transportation Access, and Housing Instability. For RN interviews, significantly more participants were classified as High Risk for Alcohol Use. Community health workers successfully conducted psychosocial screening and elicited more self-reported risk than RNs, especially lack of basic needs. Comparing the hourly salary/ wage, the cost for CHWs was 56% lower than for RNs. Preliminary findings support use of paraprofessionals for structured screening interviews. PMID:24185153

    The Dutch basic health insurance is based on the principles of regulated competition. This implies that insurers and providers compete on price and quality while the regulator sets certain rules to achieve public objectives such as solidarity. Two regulatory aspects of this scheme are that insurers are not allowed to risk rate their premiums and are compensated for predictable variation in individual medical expenses (i.e., risk equalization). Research, however, indicates that the current risk equalization is imperfect, which confronts insurers and consumers with incentives for risk selection. The goal of this paper is to review the concept, possibilities and potential effects of risk selection in the Dutch basic health insurance. We conclude that the possibilities for risk selection are numerous and a potential threat to solidarity, efficiency and quality of care. Regulators should be aware that measurement of risk selection is a methodological and data-demanding challenge. PMID:24219050

    Physical health screenings were conducted by researchers and peer wellness specialists for adults attending publicly-funded community mental health programs. A total of 457 adults with serious mental illnesses attended health fairs in 4 U.S. states and were screened for 8 common medical co-morbidities and health risk factors. Also assessed were self-reported health competencies, medical conditions, and health service utilization. Compared to non-institutionalized U.S. adults, markedly higher proportions screened positive for obesity (60%), hypertension (32%), diabetes (14%), smoking (44%), nicotine dependence (62%), alcohol abuse (17%), drug abuse (11%), and coronary heart disease (10%). A lower proportion screened positive for hyperlipidemia (7%). Multivariable random regression analysis found significant pre- to post-screening increases in participants' self-rated abilities for health practices, competence for health maintenance, and health locus of control. Screening identified 82 instances of undiagnosed diabetes, hypertension or hyperlipidemia, and 76 instances where these disorders were treated but uncontrolled. These results are discussed in the context of how this global public health approach holds promise for furthering the goal of integrating health and mental health care. PMID:25875181

  6. The perceived health risks of indoor radon gas and overhead powerlines: a comparative multilevel approach.

    2008-02-01

    Radon and overhead powerlines are two radiation risk cases that have raised varying levels of concern among the general public and experts. Despite both involving radiation-a typically feared and unseen health hazard-individuals' perceptions of the two risk cases may invoke rather different factors. We examined individual and geographic-contextual factors influencing public perceptions of the health risks of indoor radon gas and overhead powerlines in a comparative research design, utilizing a postal questionnaire with 1,528 members of the general public (response rate 28%) and multilevel modeling techniques. This study found that beliefs about the two risk cases mainly differed according to the level of "exposure"-defined here in terms of spatial proximity. We argue that there are two alternative explanations for this pattern of findings: that risk perception itself varies directly with proximity, or that risk is more salient to concerned people in the exposed areas. We also found that while people living in high radon areas are more concerned about the risks of indoor radon gas, they find these risks more acceptable and have more trust in authorities. These results might reflect the positive effects of successive radon campaigns in high radon areas, which may have raised awareness and concern, and at the same time may have helped to increase trust by showing that the government takes the health risks of indoor radon gas seriously, suggesting that genuine risk communication initiatives may have positive impacts on trust in risk management institutions.

    Information on exposure to, and health effects of, cardiovascular disease (CVD) risk factors is needed to develop effective strategies to prevent CVD events and deaths. Here, we provide an overview of the data and evidence on worldwide exposures to CVD risk factors and the associated health effects. Global comparative risk assessment studies have estimated that hundreds of thousands or millions of CVD deaths are attributable to established CVD risk factors (high blood pressure and serum cholesterol, smoking, and high blood glucose), high body mass index, harmful alcohol use, some dietary and environmental exposures, and physical inactivity. The established risk factors plus body mass index are collectively responsible for ≈9.7 million annual CVD deaths, with high blood pressure accounting for more CVD deaths than any other risk factor. Age-standardized CVD death rates attributable to established risk factors plus high body mass index are lowest in high-income countries, followed by Latin America and the Caribbean; they are highest in the region of central and eastern Europe and central Asia. However, estimates of the health effects of CVD risk factors are highly uncertain because there are insufficient population-based data on exposure to most CVD risk factors and because the magnitudes of their effects on CVDs in observational studies are likely to be biased. We identify directions for research and surveillance to better estimate the effects of CVD risk factors and policy options for reducing CVD burden by modifying preventable risk factors.

    Background Studies of family caregivers of the critically ill have mainly focused on the psychological impact of the patients’ stay in the intensive care unit and related stress. Despite known associations between stress and physical health, limited attention has been paid to the need to promote and maintain physical health in these caregivers. Objective To explore how family caregivers’ health risk behaviors are associated with patients’ preexisting care needs and the caregivers’ depressive symptoms and burden. Methods During the intensive-care-unit stay of critically ill patients (who required mechanical ventilation for ≥4 days), 50 family caregivers were surveyed to determine the caregivers’ depressive symptoms, burden, and health risk behaviors. Data were also collected on patients’ care needs before admission to the intensive care unit. Results One or more health risk behaviors were reported by 94% of family caregivers. More than 90% of caregivers reported depressive symptoms above the score indicating risk for clinical depression. A high level of burden was reported by 36% of caregivers. More health risk behaviors were associated with higher scores of depressive symptoms and burden (P<.001 for both). Caregivers’ responses did not differ according to patients’ preexisting care needs. Conclusion Health risk behaviors of family caregivers are associated with greater perceptions of burden and/or depressive symptoms but not with patients’ care needs before admission to the intensive care unit.

  9. Human health risk assessment related to contaminated land: state of the art.

    2015-08-01

    Exposure of humans to contaminants from contaminated land may result in many types of health damage ranging from relatively innocent symptoms such as skin eruption or nausea, on up to cancer or even death. Human health protection is generally considered as a major protection target. State-of-the-art possibilities and limitations of human health risk assessment tools are described in this paper. Human health risk assessment includes two different activities, i.e. the exposure assessment and the hazard assessment. The combination of these is called the risk characterization, which results in an appraisal of the contaminated land. Exposure assessment covers a smart combination of calculations, using exposure models, and measurements in contact media and body liquids and tissue (biomonitoring). Regarding the time frame represented by exposure estimates, biomonitoring generally relates to exposure history, measurements in contact media to actual exposures, while exposure calculations enable a focus on exposure in future situations. The hazard assessment, which is different for contaminants with or without a threshold for effects, results in a critical exposure value. Good human health risk assessment practice accounts for tiered approaches and multiple lines of evidence. Specific attention is given here to phenomena such as the time factor in human health risk assessment, suitability for the local situation, background exposure, combined exposure and harmonization of human health risk assessment tools.

    According to the framework of "Pressure-State-Response", this study established an indicator system which can reflect comprehensive risk of environment and health for an area at large scale. This indicator system includes 17 specific indicators covering social and economic development, pollution emission intensity, air pollution exposure, population vulnerability, living standards, medical and public health, culture and education. A corresponding weight was given to each indicator through Analytical Hierarchy Process (AHP) method. Comprehensive risk assessment of the environment and health of 58 counties was conducted in the Jiangsu province, China, and the assessment result was divided into four types according to risk level. Higher-risk counties are all located in the economically developed southern region of Jiangsu province and relatively high-risk counties are located along the Yangtze River and Xuzhou County and its surrounding areas. The spatial distribution of relatively low-risk counties is dispersive, and lower-risk counties mainly located in the middle region where the economy is somewhat weaker in the province. The assessment results provide reasonable and scientific basis for Jiangsu province Government in formulating environment and health policy. Moreover, it also provides a method reference for the comprehensive risk assessment of environment and health within a large area (provinces, regions and countries). PMID:26371016

    2015-01-01

    Background The escalating cost of global health care is driving the development of new technologies to identify early indicators of an individual’s risk of disease. Traditionally, epidemiologists have identified such risk factors using medical databases and lengthy clinical studies but these are often limited in size and cost and can fail to take full account of diseases where there are social stigmas or to identify transient acute risk factors. Objective Here we report that Web search engine queries coupled with information on Wikipedia access patterns can be used to infer health events associated with an individual user and automatically generate Web-based risk markers for some of the common medical conditions worldwide, from cardiovascular disease to sexually transmitted infections and mental health conditions, as well as pregnancy. Methods Using anonymized datasets, we present methods to first distinguish individuals likely to have experienced specific health events, and classify them into distinct categories. We then use the self-controlled case series method to find the incidence of health events in risk periods directly following a user’s search for a query category, and compare to the incidence during other periods for the same individuals. Results Searches for pet stores were risk markers for allergy. We also identified some possible new risk markers; for example: searching for fast food and theme restaurants was associated with a transient increase in risk of myocardial infarction, suggesting this exposure goes beyond a long-term risk factor but may also act as an acute trigger of myocardial infarction. Dating and adult content websites were risk markers for sexually transmitted infections, such as human immunodeficiency virus (HIV). Conclusions Web-based methods provide a powerful, low-cost approach to automatically identify risk factors, and support more timely and personalized public health efforts to bring human and economic benefits.

    2013-09-01

    The Internet has turned during the past decade into a major information resource in various domains of life and a communication venue among adolescents who seek health information via the net. The increasing availability of computers in homes, as well as wireless Internet access, means that adolescents today can go online anywhere, at any time. The media are not the leading cause of any major health problem, but they do contribute significantly to a variety of adolescent health problems, including aggressive behavior, sexual activity, drug use, obesity, sleep disorders, eating disorders, depression, suicide and self harm. This paper focuses on 3 major health issues in adolescents' Internet use: Body image and eating behaviors; sexuality and reproductive health behaviors; and self harm and suicidal behavior. This paper also demonstrates Internet venues where reliable health information is provided to young people by health professionals. Health professionals need to recognize the hazards of adolescents Internet use, and to address potential Internet abuse when encountering adolescents in clinical settings. PMID:24099822

    The epidemiologist primarily studies transitions between states of health and disease. The purpose of the present article is to define a foundational parameter for such studies, namely risk. We begin simply and build to the setting in which there is more than 1 event type (i.e., competing risks or competing events), as well as more than 1 treatment or exposure level of interest. In the presence of competing events, the risks are a set of counterfactual cumulative incidence functions for each treatment. These risks can be depicted visually and summarized numerically. We use an example from the study of human immunodeficiency virus to illustrate concepts. PMID:25660080

    2003-06-01

    A descriptive, correlational study was undertaken with 54 urban, 7th graders (age, 11-13 y) from one class. By using the Youth Risk Behaviors Surveillance System Questionnaire (YRBSS), information was collected about health risk behaviors as well as unintentional and intentional injury. Findings indicate that these adolescent students have significant fears related to their environment; they are fearful of being hurt. These students also reported increased incidence of health risk behaviors including alcohol use, carrying weapons, and staying up late at night. The findings suggest a need to understand how adolescents channel fear of harm to self into other unhealthy behaviors. Nurses are often in an ideal position to assess the health and behaviors of adolescents and to offer education, health promotion, and support to this at-risk population. PMID:12796861

    Introduction Pre-participation exams (PPEs), or sports physicals, present opportunities for health care providers to identify and discuss common adolescent health-risk behaviors. We sought to examine the prevalence of health-risk behaviors among high school athletes, and the proportion of providers who address these behaviors during PPEs. Method We used data from two statewide surveys: a survey of adolescents (n=46,492) and a survey of nurse practitioners and physicians (n=561) for this descriptive study. Results The most prevalent risk behaviors reported by student athletes were: low levels of physical activity (70%), bullying perpetration (41%), and alcohol use (41%). Most providers (≥75%) addressed many common risk behaviors during PPEs but fewer addressed bullying, violence, and prescription drug use. Topics discussed differed by provider type and patient population. Discussion Many providers addressed critical threats to adolescent health during PPEs but findings suggest potential disconnects between topics addressed during PPEs and behaviors of athletes.
