Climate Change, Human Rights, and Social Justice.

Abstract: The environmental and health consequences of climate change, which disproportionately affect low-income countries and poor people in high-income countries, profoundly affect human rights and social justice. Environmental consequences include increased temperature, excess precipitation in some areas and droughts in others, extreme weather events, and increased sea level. These consequences adversely affect agricultural production, access to safe water, and worker productivity, and, by inundating land or making land uninhabitable and uncultivatable, will force many people to become environmental refugees. Adverse health effects caused by climate change include heat-related disorders, vector-borne diseases, foodborne and waterborne diseases, respiratory and allergic disorders, malnutrition, collective violence, and mental health problems. These environmental and health consequences threaten civil and political rights and economic, social, and cultural rights, including rights to life, access to safe food and water, health, security, shelter, and culture. On a national or local level, those people who are most vulnerable to the adverse environmental and health consequences of climate change include poor people, members of minority groups, women, children, older people, people with chronic diseases and disabilities, those residing in areas with a high prevalence of climate-related diseases, and workers exposed to extreme heat or increased weather variability. On a global level, there is much inequity, with low-income countries, which produce the least greenhouse gases (GHGs), being more adversely affected by climate change than high-income countries, which produce substantially higher amounts of GHGs yet are less immediately affected. In addition, low-income countries have far less capability to adapt to climate change than high-income countries. Adaptation and mitigation measures to address climate change needed to protect human society must also be planned to protect human rights, promote social justice, and avoid creating new problems or exacerbating existing problems for vulnerable populations.

Identifying Interprofessional Global Health Competencies for 21st-Century Health Professionals

Abstract: BACKGROUND At the 2008 inaugural meeting of the Consortium of Universities for Global Health (CUGH), participantsdiscussed therapid expansionofglobalhealthprograms and thelack of standardizedcompetencies andcurriculatoguidetheseprograms.In2013,CUGHappointedaGlobalHealthCompetencySubcommitteeand chargedthissubcommitteewithidentifyingbroadglobalhealthcorecompetenciesapplicableacrossdisciplines. OBJECTIVES The purpose of this paper is to describe the Subcommittee’s work and proposed list of interprofessional global health competencies. METHODS After agreeing on a definition of global health to guide the Subcommittee’s work, members conducted an extensive literature review to identify existing competencies in all fields relevant to global health. Subcommittee members initially identified 82 competencies in 12 separate domains, and proposed fourdifferentcompetencylevels.Theproposedcompetenciesanddomainswerediscussedduringmultiple conference calls, and subcommittee members voted to determine the final competencies to be included in twoofthefourproposedcompetencylevels(globalcitizenandbasicoperationalleveleprogramoriented). FINDINGS The final proposed list included a total of 13 competencies across 8 domains for the Global Citizen Level and 39 competencies across 11 domains for the Basic Operational Program-Oriented Level. CONCLUSIONS There is a need for continued debate and dialog to validate the proposed set of competencies, and a need for further research to identify best strategies for incorporating these competencies into global health educational programs. Future research should focus on implementation and evaluation of these competencies across a range of educational programs, and further delineating the competencies needed across all four proposed competency levels.

Climate Change and Water Scarcity: The Case of Saudi Arabia

Abstract: Background Climate change is expected to bring increases in average global temperatures (1.4°C–5.8°C [34.52°F–42.44°F] by 2100) and precipitation levels to varying degrees around the globe. The availability and quality of water will be severely affected, and public health threats from the lack of this valuable resource will be great unless water-scarce nations are able to adapt. Saudi Arabia provides a good example of how the climate and unsustainable human activity go hand in hand in creating stress on and depleting water resources, and an example for adaptation and mitigation. Method A search of the English literature addressing climate change, water scarcity, human health, and related topics was conducted using online resources and databases accessed through the University at Albany, State University of New York library web page. Results Water scarcity, which encompasses both water availability and water quality, is an important indicator of health. Beyond drinking, water supply is intimately linked to food security, sanitation, and hygiene, which are primary contributors to the global burden of disease. Poor and disadvantaged populations are the ones who will suffer most from the negative effects of climate change on water supply and associated human health issues. Examples of adaptation and mitigation measures that can help reduce the strain on conventional water resources (surface waters and fossil aquifers or groundwater) include desalination, wastewater recycling and reuse, and outsourcing food items or “virtual water trade.” These are strategies being used by Saudi Arabia, a country that is water poor primarily due to decades of irresponsible irrigation practices. The human and environmental health risks associated with these adaptation measures are examined. Finally, strategies to protect human health through international collaboration and the importance of these efforts are discussed. Conclusion International, multidisciplinary cooperation and collaboration will be needed to promote global water security and to protect human health, particularly in low-income countries that do not have the resources necessary to adapt on their own.

Transmission of Ebola Virus Disease: An Overview

Abstract: Ebola is a viral illness of which the initial symptoms can include a sudden fever, intense weakness, muscle pain and a sore throat, according to the World Health Organization (WHO). Airborne transmission of Ebola virus has been hypothesized but not demonstrated in humans. Ebola is not spread through the air or by water, or in general, by food. However, in Africa, Ebola may be spread as a result of handling bushmeat (wild animals hunted for food) and contact with infected bats. The disease infects humans through close contact with infected animals, including chimpanzees, fruit bats, and forest antelope. Ebola virus can be transmitted by direct contact with blood, bodily fluids, or skin of patients with or who died of Ebola virus disease. As of late October 2014, the World Health Organization reported 13,567 suspected cases and 4922 deaths, although the agency believes that this substantially understates the magnitude of the outbreak. Experimental vaccines and treatments for Ebola are under development, but they have not yet been fully tested for safety or effectiveness.

Do Americans Understand That Global Warming Is Harmful to Human Health? Evidence From a National Survey

Abstract: Background Global warming has significant negative consequences for human health, with some groups at greater risk than others. The extent to which the public is aware of these risks is unclear; the limited extant research has yielded discrepant findings. Objectives This paper describes Americans' awareness of the health effects of global warming, levels of support for government funding and action on the issue, and trust in information sources. We also investigate the discrepancy in previous research findings between assessments based on open- versus closed-ended questions. Methods A nationally representative survey of US adults (N = 1275) was conducted online in October 2014. Measures included general attitudes and beliefs about global warming, affective assessment of health effects, vulnerable populations and specific health conditions (open- and closed-ended), perceived risk, trust in sources, and support for government response. Findings Most respondents (61%) reported that, before taking the survey, they had given little or no thought to how global warming might affect people's health. In response to a closed-ended question, many respondents (64%) indicated global warming is harmful to health, yet in response to an open-ended question, few (27%) accurately named one or more specific type of harm. In response to a closed-ended question, 33% indicated some groups are more affected than others, yet on an open-ended question only 25% were able to identify any disproportionately affected populations. Perhaps not surprising given these findings, respondents demonstrated only limited support for a government response: less than 50% of respondents said government should be doing more to protect against health harms from global warming, and about 33% supported increased funding to public health agencies for this purpose. Respondents said their primary care physician is their most trusted source of information on this topic, followed by the Centers for Disease Control and Prevention, the World Health Organization, and their local public health department. Conclusions Most Americans report a general sense that global warming can be harmful to health, but relatively few understand the types of harm it causes or who is most likely to be affected. Perhaps as a result, there is only moderate support for an expanded public health response. Primary care physicians and public health officials appear well positioned to educate the public about the health relevance of climate change

The burden of dengue and chikungunya worldwide: implications for the southern United States and California

Abstract: Background Dengue virus (DENV) spreads to humans through the bite of an infected Aedes aegypti or Aedes albopictus mosquito and is a growing public health threat to both industrialized and developing nations worldwide. Outbreaks of autochthonous dengue in the United States occurred extensively in the past but over the past 3 decades have again taken place in Florida, Hawaii, and Texas as well as in American Samoa, Guam, Northern Mariana Islands, Puerto Rico, and the US Virgin Islands. As the Aedes vectors spread worldwide it is anticipated that DENV as well as other viruses also transmitted by these vectors, such as Chikungunya virus (CHKV), will invade new areas of the world, including the United States. Objectives In this review, we describe the current burden of dengue disease worldwide and the potential introduction of DENV and CHKV into different areas of the United States. Of these areas, the state of California saw the arrival and spread of the Aedes aegypti vector beginning in 2013. This invasion presents a developing situation when considering the state’s number of imported dengue cases and proximity to northern Mexico as well as the rising specter of chikungunya in the Western hemisphere. Findings In light of the recent arrival of Aedes aegypti mosquito vectors to California, there is now a small but appreciable risk for endemic transmission of dengue and chikungunya within the State. It is likely, however, that if DENV or CHKV were to become endemic that the public health situation would be similar to that currently found along the Texas-Mexico border. The distribution of Aedes vectors in California as well as a discussion of several factors contributing to the risk for dengue importation are discussed and evaluated. Conclusions Dengue and chikungunya viruses present real risks to states where the Aedes vector is now established. Scientists, physicians, and public health authorities should familiarize themselves with these risks and prepare appropriately.

A Systematic Review of Innate Immunomodulatory Effects of Household Air Pollution Secondary to the Burning of Biomass Fuels

Abstract: Background Household air pollution (HAP)-associated acute lower respiratory infections cause 455,000 deaths and a loss of 39.1 million disability-adjusted life years annually. The immunomodulatory mechanisms of HAP are poorly understood. Objectives The aim of this study was to conduct a systematic review of all studies examining the mechanisms underlying the relationship between HAP secondary to solid fuel exposure and acute lower respiratory tract infection to evaluate current available evidence, identify gaps in knowledge, and propose future research priorities. Methods We conducted and report on studies in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. In all, 133 articles were fully reviewed and main characteristics were detailed, namely study design and outcome, including in vivo versus in vitro and pollutants analyzed. Thirty-six studies were included in a nonexhaustive review of the innate immune system effects of ambient air pollution, traffic-related air pollution, or wood smoke exposure of developed country origin. Seventeen studies investigated the effects of HAP-associated solid fuel (biomass or coal smoke) exposure on airway inflammation and innate immune system function. Results Particulate matter may modulate the innate immune system and increase susceptibility to infection through a) alveolar macrophage-driven inflammation, recruitment of neutrophils, and disruption of barrier defenses; b) alterations in alveolar macrophage phagocytosis and intracellular killing; and c) increased susceptibility to infection via upregulation of receptors involved in pathogen invasion. Conclusions HAP secondary to the burning of biomass fuels alters innate immunity, predisposing children to acute lower respiratory tract infections. Data from biomass exposure in developing countries are scarce. Further study is needed to define the inflammatory response, alterations in phagocytic function, and upregulation of receptors important in bacterial and viral binding. These studies have important public health implications and may lead to the design of interventions to improve the health of billions of people daily.

Household Air Pollution Exposures of Pregnant Women Receiving Advanced Combustion Cookstoves in India: Implications for Intervention.

Abstract: Background Household air pollution (HAP) resulting from the use of solid cooking fuels is a leading contributor to the burden of disease in India. Advanced combustion cookstoves that reduce emissions from biomass fuels have been considered potential interventions to reduce this burden. Relatively little effort has been directed, however, to assessing the concentration and exposure changes associated with the introduction of such devices in households. Objectives The aim of this study was to describe HAP exposure patterns in pregnant women receiving a forced-draft advanced combustion cookstove (Philips model HD 4012) in the SOMAARTH Demographic Development & Environmental Surveillance Site (DDESS) Palwal District, Haryana, India. The monitoring was performed as part of a feasibility study to inform a potential large-scale HAP intervention (Newborn Stove trial) directed at pregnant women and newborns. Methods This was a paired comparison exercise study with measurements of 24-hour personal exposures and kitchen area concentrations of carbon monoxide (CO) and particulate matter less than 2.5 μm in aerodynamic diameter (PM 2.5 ), before and after the cookstove intervention. Women (N = 65) were recruited from 4 villages of SOMAARTH DDESS. Measurements were performed between December 2011 and March 2013. Ambient measurements of PM 2.5 were also performed throughout the study period. Findings Measurements showed modest improvements in 24-hour average concentrations and exposures for PM 2.5 and CO (ranging from 16% to 57%) with the use of the new stoves. Only those for CO showed statistically significant reductions. Conclusion Results from the present study did not support the widespread use of this type of stove in this population as a means to reliably provide health-relevant reductions in HAP exposures for pregnant women compared with open biomass cookstoves. The feasibility assessment identified multiple factors related to user requirements and scale of adoption within communities that affect the field efficacy of advanced combustion cookstoves as well as their potential performance in HAP intervention studies.

Occupational Safety and Health in Peru.

Abstract: Peru is a country located on the Pacific coast of South America with a population of more than 30 million inhabitants. In the past 10 years, Peru has had a steady economic growth. Peru is predominantly an extractive industry country, but the manufacturing and construction sectors are booming. It is in this context that regulations have been implemented to protect the safety and health of workers. One of the most important regulations is the Law on Safety and Health at Work, which has been recently promulgated. Regulations are complemented by training and education in occupational safety and health. The measures are yet to be fully implemented thus a positive effect in reducing accidents and occupational diseases at work has not yet been seen.

Status of occupational health and safety and related challenges in expanding economy of Tanzania

Abstract: Introduction Occupational health and safety is related with economic activities undertaken in the country. As the economic activities grow and expand, occupational injuries and diseases are more likely to increase among workers in different sectors of economy such as agriculture, mining, transport, and manufacture. This may result in high occupational health and safety services demand, which might be difficult to meet by developing countries that are prioritizing economic expansion without regard to their impact on occupational health and safety. Objective To describe the status of occupational health and safety in Tanzania and outline the challenges in provision of occupational health services under the state of an expanding economy. Findings Tanzania's economy is growing steadily, with growth being driven by communications, transport, financial intermediation, construction, mining, agriculture, and manufacturing. Along with this growth, hazards emanating from work in all sectors of the economy have increased and varied. The workers exposed to these hazards suffer from illness and injuries and yet they are not provided with adequate occupational health services. Services are scanty and limited to a few enterprises that can afford it. Existing laws and regulations are not comprehensive enough to cover the entire population. Implementation of legislation is weak and does not protect the workers. Conclusions Most Tanzanians are not covered by the occupational health and safety law and do not access occupational health services. Thus an occupational health and safety services strategy, backed by legislations and provided with the necessary resources (competent experts, financial and technological resources), is a necessity in Tanzania. The existing legal provisions require major modifications to meet international requirements and standards. OHS regulations and legislations need refocusing, revision, and strengthening to cover all working population. Capacities should be improved through training and research to enable enforcement. Finally the facilities and resources should be made available for OHS services to match with the growing economy.

Review of Occupational Health and Safety Organization in Expanding Economies: The Case of Southern Africa

Abstract: Background Globally, access to occupational health and safety (OHS) by workers has remained at very low levels. The organization and implementation of OHS in South Africa, Zimbabwe, Zambia, and Botswana has remained at suboptimal levels. Inadequacy of human resource capital, training, and education in the field of OHS has had a major negative impact on the improvement of worker access to such services in expanding economies. South Africa, Zimbabwe, Zambia, and Botswana have expanding economies with active mining and agricultural activities that pose health and safety risks to the working population. Methods A literature review and country systems inquiry on the organization of OHS services in the 4 countries was carried out. Because of the infancy and underdevelopment of OHS in southern Africa, literature on the status of this topic is limited. Results In the 4 countries under review, OHS services are a function shared either wholly or partially by 3 ministries, namely Health, Labor, and Mining. Other ministries, such as Environment and Agriculture, carry small fragments of OHS function. The 4 countries are at different stages of OHS legislative frameworks that guide the practice of health and safety in the workplace. Inadequacies in human resource capital and expertise in occupational health and safety are noted major constraints in the implementation and compliance to health and safety initiatives in the work place. South Africa has a more mature system than Zimbabwe, Zambia, and Botswana. Lack of specialized training in occupational health services, such as occupational medicine specialization for physicians, has been a major drawback in Zimbabwe, Zambia, and Botswana. Discussion The full adoption and success of OHS systems in Southern Africa remains constrained. Training and education in OHS, especially in occupational medicine, will enhance the development and maturation of occupational health in southern Africa. Capacitating primary health services with basic occupational health knowledge would be invaluable in bridging the current skills deficit. Introducing short courses and foundational tracks in occupational medicine for general medical practitioners would be invaluable

Diabetes Mellitus in Peru

Abstract: Background Peru is an upper medium-income developing country with an increasing prevalence of chronic diseases, including diabetes. Objective To review and describe the epidemiology, drivers, and diabetes care plan in Peru. Methods The medical literature was reviewed based on systematic searching of PubMed, Scielo, and various gray literature from the International Diabetes Federation, World Health Organization, and local Peruvian agencies. Findings In Peru, diabetes affects 7% of the population. Type 2 diabetes accounts for 96.8% of outpatients visits with this condition. Type 1 diabetes has an incidence of 0.4/100,000 per year, and gestational diabetes affects 16% of pregnancies. The prevalence of glucose intolerance is 8.11% and that of impaired fasting glucose 22.4%. The prevalence of overweight, obesity, and metabolic syndrome in adults is 34.7%, 17.5%, and 25%, respectively. Metabolic syndrome prevalence is greater in women and the elderly and at urban and low-altitude locations. Diabetes is the eighth cause of death, the sixth cause of blindness, and the leading cause of end-stage kidney disease and nontraumatic lower limb amputation. In Peru, diabetes accounts for 31.5% of acute myocardial infarctions and 25% of strokes. Infections, diabetic emergencies, and cardiovascular disorders are the main causes for admissions, with a mortality rate Conclusions Diabetes is a major health care issue in Peru that exposes difficult challenges and shortcomings. The national strategy for tackling diabetes includes promotion of healthy lifestyles; training primary care physicians and providing them with evidence-based clinical practice guidelines, safe and effective medications, and tools for monitoring treatment; and, finally, construction of a comprehensive health care network for early referral in order to prevent, detect, and treat diabetic complications.

Chile Confronts its Environmental Health Future After 25 Years of Accelerated Growth

Abstract: Background Chile has recently been reclassified by the World Bank from an upper-middle-income country to a high-income country. There has been great progress in the last 20 to 30 years in relation to air and water pollution in Chile. Yet after 25 years of unrestrained growth, there remain clear challenges posed by air and water pollution, as well as climate change. Objective The aim of this study was to review environmental health in Chile. Methods In late 2013, a 3-day workshop on environmental health was held in Santiago, Chile, bringing together researchers and government policymakers. As a follow-up to that workshop, here we review the progress made in environmental health in the past 20 to 30 years and discuss the challenges of the future. We focus on air and water pollution and climate change, which we believe are among the most important areas of environmental health in Chile. Results Air pollution in some cities remains among the highest in the continent. Potable water is generally available, but weak state supervision has led to serious outbreaks of infectious disease and ongoing issues with arsenic exposure in some regions. Climate change modeling in Chile is quite sophisticated, and a number of the impacts of climate change can be reasonably predicted in terms of which areas of the country are most likely to be affected by increased temperature and decreased availability of water, as well as expansion of vector territory. Some health effects, including changes in vector-borne diseases and excess heat mortality, can be predicted. However, there has yet to be an integration of such research with government planning. Conclusions Although great progress has been made, currently there are a number of problems. We suspect that the Chilean experience in environmental health may be of some use for other Latin American countries with rapid economic development.

Malaria and macronutrient deficiency as correlates of anemia in young children: a systematic review of observational studies.

Abstract: Background Anemia is a leading cause of pediatric mortality and impaired development and is highly prevalent in young children in sub-Saharan Africa. Populations most affected by anemia also often are at high risk for malaria and macronutrient deficiency, conditions that may exacerbate anemia. Due to its multifactorial etiology, anemia presents a significant global health challenge, and successful interventions targeting anemia require a greater understanding of the relative and interacting contributions of malaria and undernutrition. Objectives The aim of this study was to assess the associations of malaria and undernutrition, indicated by stunting and wasting, with anemia in young children using a systematic review of observational studies. Methods Searches were conducted in MEDLINE and Scopus. Articles were screened and reviewed for inclusion by two reviewers. Studies published after 1990 that measured anemia, Plasmodium falciparum malaria, and stunting or wasting in children aged 5 years or under were included. Findings Of 620 articles reviewed, 15 studies from 9 countries in sub-Saharan Africa were included. Statistical approaches and anemia measurement varied widely, so synthesis was qualitative. Thirteen studies found that malaria infection was associated with anemia or lowered hemoglobin; in these studies, malaria accounted for more of the variation in anemia than nutritional status. In contrast, only 7 of the 13 studies investigating stunting and 3 of the 6 studies investigating wasting as correlates of anemia observed statistically significant associations at α = 0.05. The role of nutrition in anemia may differ by country. Conclusions Observational epidemiologic studies consistently demonstrate that malaria is an important correlate of anemia in young children; however, the roles of stunting and wasting and interactions between malaria and nutrition require further investigation. Based on the current evidence, these findings suggest that global health strategies to reduce the burden of anemia should prioritize malaria prevention and support research on alternative causes of anemia that reflect local conditions.

Climate Change and Health: Transcending Silos to Find Solutions

Abstract: Background Climate change has myriad implications for the health of humans, our ecosystems, and the ecological processes that sustain them. Projections of rising greenhouse gas emissions suggest increasing direct and indirect burden of infectious and noninfectious disease, effects on food and water security, and other societal disruptions. As the effects of climate change cannot be isolated from social and ecological determinants of disease that will mitigate or exacerbate forecasted health outcomes, multidisciplinary collaboration is critically needed. Objectives The aim of this article was to review the links between climate change and its upstream drivers (ie, processes leading to greenhouse gas emissions) and health outcomes, and identify existing opportunities to leverage more integrated global health and climate actions to prevent, prepare for, and respond to anthropogenic pressures. Methods We conducted a literature review of current and projected health outcomes associated with climate change, drawing on findings and our collective expertise to review opportunities for adaptation and mitigation across disciplines. Findings Health outcomes related to climate change affect a wide range of stakeholders, providing ready collaborative opportunities for interventions, which can be differentiated by addressing the upstream drivers leading to climate change or the downstream effects of climate change itself. Conclusions Although health professionals are challenged with risks from climate change and its drivers, the adverse health outcomes cannot be resolved by the public health community alone. A phase change in global health is needed to move from a passive responder in partnership with other societal sectors to drive innovative alternatives. It is essential for global health to step outside of its traditional boundaries to engage with other stakeholders to develop policy and practical solutions to mitigate disease burden of climate change and its drivers; this will also yield compound benefits that help address other health, environmental, and societal challenges.

An Epidemiologic Analysis of Diabetes in Colombia.

Abstract: Background The burden of diabetes is a global problem, wherein the significant growth of diabetes in Colombia reflects a complex pathophysiology and epidemiology found in many other South American nations. Objectives The aim of this study was to analyze epidemiologic data from Colombia and the South American region in general to identify certain disease drivers and target them for intervention to curb the increasing prevalence of diabetes. Methods A detailed search was conducted using MEDLINE, SciELO, HINARI, LILACS, IMBIOMED, and Latindex databases, in addition to clinical practice guidelines, books, manuals, and other files containing relevant and verified information on diabetes in Colombia. Findings According to the International Diabetes Federation and the World Health Organization, the prevalence of diabetes in Colombia is 7.1% and 8.5%, respectively. In contrast, a national survey in Colombia shows a prevalence ranging from 1.84% to 11.2%, depending on how the diagnosis is made, the criteria used, and the age range studied. The prevalence exclusively in rural areas ranges from 1.4% to 7.9% and in urban areas from 1% to 46%. The estimated mean overall (direct and indirect) cost attributed to type 2 diabetes is 5.7 billion Colombian pesos (US $2.7 million). Diabetes is the fifth leading cause of death in Colombia with a rate of 15 deaths per 100,000 individuals. Conclusions Based on a clustering of factors, 4 relevant disease drivers emerge that may account for the epidemiology of diabetes in Colombia: demographic transition, nutritional transition, forced displacement/internal migration and urban development, and promotion of physical activity.

Evaluation Studies on Education in Occupational Safety and Health: Inspiration for Developing Economies

Abstract: BACKGROUND Education and training of students, workers, and professionals are essential for occupational safety and health (OSH). We noticed a lack of debate on how to advance coverage and quality of OSH education given high shortages in developing economies. OBJECTIVES International discussion on future options might be stimulated by an overview of recent studies. METHODS We employed a search of the Cochrane Library and PubMed/MEDLINE databases for articles from the last decade on evaluation of OSH education. FINDINGS We selected 121 relevant studies and 6 Cochrane reviews. Most studies came from the United States, Western Europe, and Asia. Studies from low-income countries were scarce. From a global perspective, the number of evaluation studies found was disappointingly low and the quality needs improvement. Most commonly workers’ education was evaluated, less often education of students, supervisors, and OSH professionals. Interactive e-cases and e-learning modules, video conferences, and distance discussion boards are inspiring educational methods, but also participatory workshops and educational plays. Ways to find access to underserved populations were presented and evaluated, such as educational campaigns, farm safety days, and OSH expert-supported initiatives of industrial branch organizations, schools, and primary, community, or hospital-based health care. Newly educated groups were immigrant workers training colleagues, workers with a disease, managers, and family physicians. CONCLUSIONS Developing economies can take advantage of a variety of online facilities improving coverage and quality of education. Blended education including face-to-face contacts and a participatory approach might be preferred. For workers, minor isolated educational efforts are less effective than enhanced education or education as part of multifaceted preventive programs. Collaboration of OSH experts with other organizations offers opportunities to reach underserved worker populations. Increasing international collaboration is a promise for the future. National legislation and government support is necessary, placing OSH education high on the national agenda, with special attention for most needed professionals and for underserved workers in high-risk jobs such as in the informal sector. International support can be boosted by a highlevel international task force on education and training, funded programming, and a global online platform.

Diabetes Care in Brazil.

Abstract: Background The diabetes epidemic affects most countries across the world and is increasing at alarming rates in Latin America. Nearly 12 million individuals have diabetes in Brazil, and the current prevalence ranges from 6.3% to 13.5%, depending on the region and the diagnostic criteria adopted in each study. Objective To provide an overview of diabetes care in Brazil, focusing on studies of diabetes epidemiology, prevalence of patients within the standard targets of care, and economic burden of diabetes and its complications. Methods SciELO and PubMed searches were performed for the terms “diabetes,” “Brazil,” “Brazilian,” and “health system”; relevant literature from 1990 to 2015 was selected. Additional articles identified from reference list searches were also included. All articles selected were published in Portuguese and/or English. Findings Recent studies detected a prevalence of gestational diabetes mellitus of nearly 20%. Among patients with type 1 diabetes, almost 90% fail to reach target of glycemic control, with less than 30% receiving treatment for both hypertension and dyslipidemia. More than 75% of patients with type 2 diabetes are either overweight or obese. Most of these patients fail to reach glycemic targets (42.1%) and less than 30% reached the target for systolic and diastolic blood pressure, body mass index, or low-density lipoprotein cholesterol. Only 0.2% of patients reach all these anthropometric and metabolic targets. Conclusions Brazil is the fourth country in the world in number of patients with diabetes. Regardless of the diabetes type, the majority of patients do not meet other metabolic control goals. The economic burden of diabetes and its complications in Brazil is extremely high, and more effective approaches for preventions and management are urgently needed.

Occupational Health Services Integrated in Primary Health Care in Iran

Abstract: Introduction A healthy workforce is vital for maintaining social and economic development on a global, national and local level. Around half of the world's people are economically active and spend at least one third of their time in their place of work while only 15% of workers have access to basic occupational health services. According to WHO report, since the early 1980s, health indicators in Iran have consistently improved, to the extent that it is comparable with those in developed countries. In this paper it was tried to briefly describe about Health care system and occupational Health Services as part of Primary Health care in Iran. Methods To describe the health care system in the country and the status of occupational health services to the workers and employers, its integration into Primary Health Care (PHC) and outlining the challenges in provision of occupational health services to the all working population. Findings Iran has fairly good health indicators. More than 85 percent of the population in rural and deprived regions, for instance, have access to primary healthcare services. The PHC centers provide essential healthcare and public-health services for the community. Providing, maintaining and improving of the workers' health are the main goals of occupational health services in Iran that are presented by different approaches and mostly through Workers' Houses in the PHC system. Conclusions Iran has developed an extensive network of PHC facilities with good coverage in most rural areas, but there are still few remote areas that might suffer from inadequate services. It seems that there is still no transparent policy to collaborate with the private sector, train managers or provide a sustainable mechanism for improving the quality of services. Finally, strengthening national policies for health at work, promotion of healthy work and work environment, sharing healthy work practices, developing updated training curricula to improve human resource knowledge including occupational health professionals are recommended.

Temperature and Humidity Effects on Hospital Morbidity in Darwin, Australia

Abstract: BACKGROUND Many studies have explored the relationship between temperature and health in the context of a changing climate, but few have considered the effects of humidity, particularly in tropical locations, on human health and well-being. To investigate this potential relationship, this study assessed the main and interacting effects of daily temperature and humidity on hospital admission rates for selected heat-relevant diagnoses in Darwin, Australia. METHODS Univariate and bivariate Poisson generalized linear models were used to find statistically significant predictors and the admission rates within bins of predictors were compared to explore nonlinear effects. FINDINGS The analysis indicated that nighttime humidity was the most statistically significant predictor (P < 0.001), followed by daytime temperature and average daily humidity (P < 0.05). There was no evidence of a significant interaction between them or other predictors. The nighttime humidity effect appeared to be strongly nonlinear: Hot days appeared to have higher admission rates when they were preceded by high nighttime humidity. CONCLUSIONS From this analysis, we suggest that heat-health policies in tropical regions similar to Darwin need to accommodate the effects of temperature and humidity at different times of day. KEY W ORDS admissions, heat stress, hyperthermia, sleep disruption, tropical

The Human Rights and Social Justice Scholars Program: a collaborative model for preclinical training in social medicine.

Abstract: Background Despite the importance of the role social justice takes in medical professionalism, the need to train health professionals to address social determinants of health, and medical trainees' desire to eliminate health disparities, undergraduate medical education offers few opportunities for comprehensive training in social justice. The Human Rights and Social Justice (HRSJ) Scholars Program at the Icahn School of Medicine at Mount Sinai is a preclinical training program in social medicine consisting of 5 components: a didactic course, faculty and student mentorship, research projects in social justice, longitudinal policy and advocacy service projects, and a career seminar series. Objectives The aim of this article is to describe the design and implementation of the HRSJ curriculum with a focus on the cornerstone of the HRSJ Scholars Program: longitudinal policy and advocacy service projects implemented in collaboration with partner organizations in East Harlem. Furthermore, we describe the results of a qualitative survey of inaugural participants, now third-year medical students, to understand how their participation in this service-learning component affected their clinical experiences and professional self-perceptions. Conclusion Ultimately, through the implementation and evaluation of the HRSJ Scholars Program, we demonstrate an innovative model for social justice education; the enduring effect of service-learning experiences on participants' knowledge, skills, and attitudes; and the potential to increase community capacity for improved health through a collaborative educational model.

Working Conditions, Workplace Violence, and Psychological Distress in Andean Miners: A Cross-sectional Study Across Three Countries

Abstract: Background Psychosocial working conditions are well-known determinants of poor mental health. However, studies in mining populations where employment and working conditions are frequently precarious have, to our knowledge, only focused on occupational accidents and diseases. Objectives The aim of this study was to assess psychosocial working conditions and psychological distress in Andean underground miners. Methods The study population consisted of 153 Bolivian miners working in a silver mining cooperative, 137 Chilean informal gold miners, and 200 formal Peruvian silver miners employed in a remote setting. High work demands, minimal work control, minimal social support at work, and workplace exposure to violence and bullying were assessed using the Spanish short form of the European Working Condition Survey. A general health questionnaire score >4 was used as cutoff for psychological distress. Associations between psychosocial work environment and psychological distress were tested using logistic regression models controlling for potential confounding and effect modification by country. Findings Prevalence of psychological distress was 82% in the Bolivian cooperative miners, 29% in the Peruvian formal miners, and 22% in the Chilean informal miners (pχ2 Conclusions Psychological distress is associated with the psychosocial work environment in Andean underground miners. Interventions in mining populations should take the psychosocial work environment into account.

Effects of Occupational Health and Safety on Healthy Lifestyle Behaviors of Workers Employed in a Private Company in Turkey.

Abstract: Background It has been suggested that inappropriate working conditions and unsafe environments at construction sites, longer working hours, and inadequate workplaces adversely affect the health behaviors of workers. Objective The aim of this study was to evaluate the effect of occupational health and safety (OHS) practices on healthy lifestyle behaviors of workers employed at a construction site of a private company in Gaziantep, Turkey. Methods The sampling size of this descriptive study consisted of 400 employees working at the construction site between December 2014 and January 2015. In all, 341 employees still working or participating in the study during the period of this questionnaire study were included in the sampling. Data from the survey were derived from responses to questions regarding sociodemographic characteristics, OHS applications, health state, and working conditions, as well as to the questions in on the Healthy Lifestyle Behaviors Scale (HLBS), under direct surveillance. Findings Male workers with a mean age of 30.61 ± 8.68 years constituted the study population. Of the workers, 41.9% had a primary school education. The majority received professional and OHS training (65.7% and 79.2%, respectively). Although 83.9% reported using personal protective equipment (PPE), only 2.1% said they had experienced an occupational accident. Total mean score of HLBS scale was 116.91 ± 25.62 points. Workers who had positive thoughts about their jobs demonstrated healthy lifestyle behaviors (P = .0001). A positive direct correlation was detected between the training the workers received and the use of PPE (P = .0001). In all, 38.1% of the workers reported experiencing work stress at the time of the study. Mean HLBS scores of those experiencing work stress were lower than the scores for workers not experiencing stress (P Conclusion Receiving OHS and professional training and using of PPE favorably affect healthy lifestyle behaviors.

Molecular Diagnosis of TB in the HIV Positive Population.

Abstract: Background Tuberculosis (TB) remains a major contributor to morbidity and mortality in HIV-positive individuals, causing 1.1 million incident cases and 0.32 million deaths in 2012. Diagnosis of TB is particularly challenging in HIV-coinfected individuals, due to a high frequency of smear-negative disease, atypical presentations, and extrapulmonary TB. Objective The aim of this article was to review the current literature on molecular diagnostics for TB with an emphasis on the performance of these diagnostic tests in the HIV-positive population. Methods We searched the PubMed database using at least one of the terms TB, HIV, diagnostics, Xpert MTB/RIF, nucleic acid amplification tests, drug susceptibility testing, RNA transcription , and drew on World Health Organization publications. Findings With increased focus on reducing TB prevalence worldwide, a new set of tools for diagnosing the disease have emerged. Molecular tools such as Xpert MTB/RIF and line-probe assays are now in use or are being rolled out in many regions. The diagnostic performance of these and other molecular assays are discussed here as they pertain to the HIV-positive population. Conclusions Molecular diagnostics offer a useful addition and at times, alternative, to traditional culture methods for the diagnosis of TB. However, most of these tests suffer from decreased accuracy in the HIV-positive population.

Health in National Climate Change Adaptation Planning

Abstract: Adaptation has been a critical component of the international negotiations under the United Nations Framework Convention on Climate Change (UNFCCC) from the beginning. When signing the convention, all countries agreed to produce regular national communications covering their emissions inventory, current impacts and projected risks of climate change, adaptation options to prepare for and reduce those risks, and mitigation options to reduce greenhouse gas emissions and transition to a green economy. The least developed countries (LDCs) also developed National Adaptation Programmes of Action (NAPAs) to identify their urgent and immediate adaptation needs. Building on the experience gained through the NAPA process, including implementation of adaptation options to address urgent national needs, National Adaptation Plans (NAPs) are under development by LDCs and other developing countries to identify and address medium and long-term adaptation needs. The NAP process was initiated at the UNFCCC Conference of the Parties (COP) meeting in Cancun, Mexico, in 2010, at which countries acknowledged that national adaptation planning is an important process by which developing countries can assess their vulnerabilities, risks, and adaptation options. Further, the COP acknowledged that because the development challenges for LDCs are magnified by climate change, adaptation planning should move from primarily focusing on current climate variability and recent climate change to focusing more broadly on increasing resilience within the context of sustainable development planning. The COP established the NAP process to facilitate effective and efficient adaptation planning in

Occupational Risks of Health Professionals in Turkey as an Emerging Economy.

Abstract: Background Health services are one of the work areas that contain important risks in terms of the occupational health and safety of the laborer. Professionals in various areas of health services encounter biological, chemical, physical, ergonomic, and psychosocial risks, particularly in hospitals. Objectives This study has been performed to evaluate the impacts of the occupational risks on health of health professionals in Turkey. Findings In Turkey, as an emerging economy, the history of studies on health professionals is not longstanding. There have been various regulations intended for the occupational health and safety of health professionals in line with the Regulation of the Provision on Patient and Staff Safety prepared in 2012. However, applications can differ from region to region, institution to institution, and person to person. Conclusions We believe that this review will lead health professionals to be aware of occupational risks and contribute to planning health services for health professionals.

Fall Injuries in Nepal: A Countrywide Population-based Survey.

Abstract: Background An estimated 424,000 fatal falls occur globally each year, making falls the second leading cause of unintentional injury-related deaths after road traffic injuries. More than 80% of fall-related fatalities occur in low- and middle-income countries. Data from low-income South Asian countries like Nepal are lacking, particularly at the population level. The aim of this study was to provide an estimate of fall-injury prevalence and the number of fall injury-related deaths countrywide in Nepal and to describe the epidemiology of fall injuries in Nepal at the community level. Methods A countrywide cross-sectional study was performed in 15 of the 75 districts in Nepal using the Surgeons OverSeas Assessment of Surgical Need (SOSAS) survey tool. The SOSAS survey gathers data in 2 sections: demographic data, including the household’s access to health care and recent deaths in the household, and assessment of a representative spectrum of surgical conditions, including injuries. Data was collected regarding an individuals’ experience of injury including road traffic injuries, falls, penetrating trauma, and burns. Data included anatomic location, timing of injury, and whether health care was sought. If health care was not sought, the reason for barrier to care was included. Descriptive statistics were used to analyze the data. Results Of 2695 individuals from 1350 households interviewed, 141 reported injuries secondary to falls (5.2%; 95% confidence interval [CI], 4.4%–6.1%), with a mean age of 30.7 years; 58% were male. Falls represented 37.2% of total injuries (n = 379) reported (95% CI, 32.3%–42.3%). Twelve individuals who suffered from a fall injury were unable to access surgical care (8.5%; 95% CI, 4.5%–14.4%). Reasons for barrier to care included no money for health care (n = 3), facility/personnel not available (n = 7), and fear/no trust (n = 2). Of the 80 recent deaths reported, 7 were due to fall injury (8.8%; 95% CI, 3.6%–17.2%), and patients had a mean age of 46 years (SD 22.8). Surgical care was not delivered to those who died for the following reasons: no time (n = 4), facility/personnel not available (n = 1), fear/no trust (n = 1), and no need (n = 1). Conclusion The Nepal SOSAS study provides countrywide, population-based data on fall-injury prevalence in Nepal and has identified falls as a crucial public health concern. These data highlight persistent barriers to access to care for the injured and the need to improve trauma care systems in developing countries such as Nepal.

Defining Polio: Closing the Gap in Global Surveillance.

Abstract: Background By late 2012 the Global Polio Eradication Initiative (GPEI) had nearly eradicated this ancient infectious disease. Successful surveillance programs for acute flaccid paralysis however rely on broad governmental support for implementation. With the onset of conflict, public health breakdown has contributed to the resurgence of polio in a number of regions. The current laboratory based case definition may be a contributory factor in these regions. Objective We sought to compare case definition rates using strict laboratory based criteria to rates obtained using the clinical criteria in modern day Syria. We also sought to examine this distribution of cases by sub-region. Methods We examined the World Health Organization (WHO) reported figures for Syria from 2013–2014 using laboratory based criteria. We compared these with cases obtained when clinical criteria were applied. In addition we sought data from the opposition controlled Assistance Coordination Unit which operates in non-Government controlled areas where WHO data maybe incomplete. Cases were carefully examined for potential overlap to avoid double reporting. Findings Whilst the WHO data clearly confirmed the polio outbreak in Syria, it did so with considerable delay and with under reporting of cases, particularly from non-government controlled areas. In addition, laboratory based case definition led to a substantial underestimate of polio (36 cases) compared with those found with the clinically compatible definition (an additional 46 cases). Rates of adequate diagnostic specimens from suspected cases are well below target, no doubt reflecting the effect of conflict in these areas. Conclusions We have identified a gap in the surveillance of polio, a global threat. The current laboratory based definition, in the setting of conflict and insecurity, leads to under diagnosis of polio with potential delays and inadequacies in coordinating effective responses to contain outbreaks and eradicate polio. Breakdown in public health measures as a contributing factor is likely to result in a resurgence of previously controlled infectious diseases. The clinical definition should be reinstituted to supplement the lab-based definition.

Climate Change and Health Adaptation: Consequences for Indigenous Physical and Mental Health.

Abstract: Low socioeconomic status contributes to poor health in disadvantaged populations globally. Poverty, limited education, poor diets, and higher exposure to other health risks are accepted as contributing factors. That these factors also impede physiologic and social adaptations to novel health stressors is less widely recognized, but will affect how humanity copes with the increasingly important health stressor of climate change. This viewpoint proposes a typology of health adaptations: physiologic, personal and household, and communityand state-level adaptation. This framework is used to examine likely effects of climate change and adaptation on the health of Indigenous Australians, a group with low socioeconomic status that shares many traits with other Indigenous people globally.
