COVID-19 and heat waves: New challenges for healthcare systems.

Heat waves and Covid-19 overlap, as this pandemic continues into summer 2021. Using a narrative review, we identified overlapping risk groups and propose coping strategies. The high-risk groups for heat-related health problems as well as for high-risk COVID-19 groups overlap considerably (elderly with pre-existing health conditions). Health care facilities will again be challenged by Covid-19 during heat waves. Health care personnel are also at risk of developing heat related health problems during hot periods due to the use of personal protective equipment to shield themselves from SARS-CoV-2 and must therefore be protected from excessive heat periods. Some existing recommendations for heat health protection contradict recommendations for COVID-19 protection. This paper provides a preliminary overview of possible strategies and interventions to tackle these ambiguities. The existing recommendations for protection against heat-related illnesses need revisions to determine whether they include essential aspects of infection control and occupational safety and how they may be supplemented.

COVID-19 and thermoregulation-related problems: Practical recommendations.

The COVID-19 pandemic started in the cold months of the year 2020 in the Northern hemisphere. Concerns were raised that the hot season may lead to additional problems as some typical interventions to prevent heat-related illness could potentially conflict with precautions to reduce coronavirus transmission. Therefore, an international research team organized by the Global Health Heat Information Network generated an inventory of the specific concerns about this nexus and began to address the issues. Three key thermal and covid-19 related topics were highlighted: 1) For the general public, going to public cool areas in the hot season interferes with the recommendation to stay at home to reduce the spread of the virus. Conflicting advice makes it necessary to revise national heat plans and alert policymakers of this forecasted issue. 2) For medical personnel working in hot conditions, heat strain is exacerbated due to a reduction in heat loss from wearing personal protective equipment to prevent contamination. To avoid heat-related injuries, medical personnel are recommended to precool and to minimize the increase in body core temperature using adopted work/rest schedules, specific clothing systems, and by drinking cold fluids. 3) Fever, one of the main symptoms of COVID-19, may be difficult to distinguish from heat-induced hyperthermia and a resting period may be necessary prior to measurement to avoid misinterpretation. In summary, heat in combination with the COVID-19 pandemic leads to additional problems; the impact of which can be reduced by revising heat plans and implementing special measures attentive to these compound risks.

Developing digital educational materials for nursing and sustainability: The results of an observational study.

BACKGROUND: There is limited European literature on nursing and sustainability; nursing students are poorly prepared on the connections between resources, climate change, sustainability, and health, so they must acquire knowledge and develop skills and competencies in this field. The use of digital technologies and teaching via E-learning has grown, and has been widely adopted as a learning method for nursing. OBJECTIVES: The aim of the current study was to test and evaluate digital educational materials on environmental sustainability and health, in the context of university nursing education in different European countries. DESIGN: An observational cross-sectional design. SETTINGS: University of Plymouth, University of Jaén, and University of Esslingen for Nursing Degree Studies. PARTICIPANTS: 299 nursing students: 161 students from University of Jaén; 106 from Plymouth; and 32 from Esslingen. 22 professional evaluators with different profiles were recruited: Teachers, Clinical professionals, Delphi Experts, and Technical Experts. METHODS: We conducted a piloting and validation process. The materials were designed and adapted to the NurSusTOOLKIT Sustainability Literacy and Competency framework. Evaluation was developed by professionals and students. We used the Spanish Standard for the assessment of Digital Educational Material Quality at University level questionnaire. All students provided informed consent prior to taking part in the learning and evaluation. RESULTS: The overall evaluations of materials by students and professionals were 7.98±1.28 and 8.50±1.17, respectively. The Ability to generate learning was scored higher among students (mean difference: 0.84; 0.22-1.47; p=0.008). In the overall assessment by students, statistically significant differences were found between the three universities (Welch: 11.69, p<0.001). CONCLUSIONS: Students, professionals, and technical experts considered the materials to be very good quality, especially regarding the quality of contents, format, and design. For students, these materials can generate reflection and learning regarding environmental and health issues during nursing training.

New frontiers for environmental epidemiology in a changing world.

BACKGROUND: In the next 25years, transformative changes, in particular the rapid pace of technological development and data availability, will require environmental epidemiologists to prioritize what should (rather than could) be done to most effectively improve population health. OBJECTIVES: In this essay, we map out key driving forces that will shape environmental epidemiology in the next 25years. We also identify how the field should adapt to best take advantage of coming opportunities and prepare for challenges. DISCUSSION: Future environmental epidemiologists will face a world shaped by longer lifespans but also larger burdens of chronic health conditions; shifting populations by region and into urban areas; and global environmental change. Rapidly evolving technologies, particularly in sensors and OMICs, will present opportunities for the field. How should it respond? We argue, the field best adapts to a changing world by focusing on healthy aging; evidence gaps, especially in susceptible populations and low-income countries; and by developing approaches to better handle complexity and more formalized analysis. CONCLUSIONS: Environmental epidemiology informing disease prevention will continue to be valuable. However, the field must adapt to remain relevant. In particular, the field must ensure that public health importance drives research questions, while seizing the opportunities presented by new technologies. Environmental epidemiologists of the future will require different, refined skills to work effectively across disciplines, ask the right questions, and implement appropriate study designs in a data-rich world.

Including sustainability issues in nurse education: A comparative study of first year student nurses' attitudes in four European countries.

INTRODUCTION: Education in sustainable development is a goal recognised by a large number of countries and a vital concept in healthcare. It is therefore important that nurse education incorporates elements of sustainable development into nursing education curricula. However, there is limited research on student nurses' attitudes towards sustainability and no comparison of attitudes towards sustainability and its inclusion in the nursing curriculum across Europe. AIM: This project aims to assess student nurses' attitudes towards sustainability, its relevance to nursing and its inclusion in the nursing curricula. 1. To assess base-line attitudes at the start of nursing and midwifery training; 2. To compare sustainability awareness between students participating in training in a number of European universities. DESIGN: A comparative survey design using the Sustainability Attitudes in Nursing Survey (SANS_2) questionnaire. SETTINGS: Nursing classes of Universities and Nursing Schools in four European countries were investigated using a questionnaire consisting of five sustainability-related items. PARTICIPANTS: 916 nursing students (UK: 450, Germany: 196, Spain: 124, Switzerland: 146). DATA ANALYSIS: Standard descriptive and inferential statistical methods were used to establish psychometric quality (Principal Components Analysis, Cronbach's alpha, Pearson correlations) and compare student nurses from the four countries. RESULTS: The reliability of SANS_2 was good (Cronbach's alpha=.82) and the five items loaded on a single factor which explained 58% of variance. ANOVA of the SANS_2 total score showed significant differences between countries with German nursing students showing more sustainability awareness than students from the UK and Spain. CONCLUSIONS: SANS_2 is a reliable instrument to assess nursing students' sustainability awareness; there are significant differences in sustainability awareness of students of different European countries. Limitations of the study include non-random sampling, possible method effects and social desirability effects. RELEVANCE TO CLINICAL PRACTICE: Sustainability will become increasingly important in clinical practice; greater knowledge about the attitudes of nurses towards sustainability can support the development and testing of sustainability-focused teaching and learning materials.

Climate Change Effects on Heat- and Cold-Related Mortality in the Netherlands: A Scenario-Based Integrated Environmental Health Impact Assessment.

Although people will most likely adjust to warmer temperatures, it is still difficult to assess what this adaptation will look like. This scenario-based integrated health impacts assessment explores baseline (1981-2010) and future (2050) population attributable fractions (PAF) of mortality due to heat (PAFheat) and cold (PAFcold), by combining observed temperature-mortality relationships with the Dutch KNMI'14 climate scenarios and three adaptation scenarios. The 2050 model results without adaptation reveal a decrease in PAFcold (8.90% at baseline; 6.56%-7.85% in 2050) that outweighs the increase in PAFheat (1.15% at baseline; 1.66%-2.52% in 2050). When the 2050 model runs applying the different adaptation scenarios are considered as well, however, the PAFheat ranges between 0.94% and 2.52% and the PAFcold between 6.56% and 9.85%. Hence, PAFheat and PAFcold can decrease as well as increase in view of climate change (depending on the adaptation scenario). The associated annual mortality burdens in 2050-accounting for both the increasing temperatures and mortality trend-show that heat-related deaths will range between 1879 and 5061 (1511 at baseline) and cold-related deaths between 13,149 and 19,753 (11,727 at baseline). Our results clearly illustrate that model outcomes are not only highly dependent on climate scenarios, but also on adaptation assumptions. Hence, a better understanding of (the impact of various) plausible adaptation scenarios is required to advance future integrated health impact assessments.

Climate Change and Infectious Disease Risk in Western Europe: A Survey of Dutch Expert Opinion on Adaptation Responses and Actors.

There is growing evidence of climate change affecting infectious disease risk in Western Europe. The call for effective adaptation to this challenge becomes increasingly stronger. This paper presents the results of a survey exploring Dutch expert perspectives on adaptation responses to climate change impacts on infectious disease risk in Western Europe. Additionally, the survey explores the expert sample's prioritization of mitigation and adaptation, and expert views on the willingness and capacity of relevant actors to respond to climate change. An integrated view on the causation of infectious disease risk is employed, including multiple (climatic and non-climatic) factors. The results show that the experts consider some adaptation responses as relatively more cost-effective, like fostering interagency and community partnerships, or beneficial to health, such as outbreak investigation and response. Expert opinions converge and diverge for different adaptation responses. Regarding the prioritization of mitigation and adaptation responses expert perspectives converge towards a 50/50 budgetary allocation. The experts consider the national government/health authority as the most capable actor to respond to climate change-induced infectious disease risk. Divergence and consensus among expert opinions can influence adaptation policy processes. Further research is necessary to uncover prevailing expert perspectives and their roots, and compare these.

[Climate change and health in the Netherlands]. / Klimaatverandering en gezondheid in Nederland.

Climate change possibly affects public health in the Netherlands, including changes in (a) temperature-related effects, heat stress and air pollution, (b) allergies, (c) vector borne infectious disease, and (d) food- and waterborne infectious disease. Due to many prevailing uncertainties, opinions differ regarding the exact size of the expected health risks and the speed at which these might occur, as well as regarding to what degree society would need to or could adapt to these potential health effects. Thus, the gaps in our knowledge are substantial. Scientists and experts are clearly concerned about the limited amount of attention being paid to health effects of climate change in the Netherlands. In response, a proposal for a research programme 'Klimaatverandering en Gezondheid' ('Climate change and health') has been developed over the past year.

The health impacts of globalization: a conceptual framework.

This paper describes a conceptual framework for the health implications of globalization. The framework is developed by first identifying the main determinants of population health and the main features of the globalization process. The resulting conceptual model explicitly visualises that globalization affects the institutional, economic, social-cultural and ecological determinants of population health, and that the globalization process mainly operates at the contextual level, while influencing health through its more distal and proximal determinants. The developed framework provides valuable insights in how to organise the complexity involved in studying the health effects resulting from globalization. It could, therefore, give a meaningful contribution to further empirical research by serving as a 'think-model' and provides a basis for the development of future scenarios on health.

The epidemiologic transition in Peru / La transición epidemiológica en el Perú

En el presente trabajo se examina la transición epidemiológica en el Perú y se demuestra que los cambios observados en la situación de salud del país constituyen un buen ejemplo del modelo de transición no occidental que describe los cambios epidemiológicos producidos a lo largo del tiempo en países en desarrollo en función de tres etapas. Actualmente el Perú se encuentra en la tercera etapa de este modelo y tiene una carga de morbilidad que abarca tres componentes. Tiene, en primer lugar, problemas antiguos que aún no se han resuelto, como el de las enfermedades infecciosas "tradicionales" (por ej., las infecciones respiratorias agudas) y el de las elevadas tasas de mortalidad materna. También tiene, en segundo lugar, algunos problemas que apenas empiezan a aflorar: las enfermedades cardiovasculares y las neoplasias malignas se están incrementando, el paludismo y otras enfermedades más antiguas están reapareciendo, y la infección por VIH y el sida, más algunas otras enfermedades, han surgido por primera vez. En tercer lugar, el Perú adolece de una poca disponibilidad de buenos servicios de salud. En este contexto, el presente trabajo examina la gran falta de equidad en el Perú en lo concerniente a algunos indicadores de salud importantes (por ej., la esperanza de vida, la tasa de mortalidad, la tasa de fecundidad, y el acceso a seguro médico y a servicios de salud), a la luz del concepto de "polarización epidemiológica". Este último es un proceso según el cual la distribución desigual de la riqueza, de los riesgos de salud, y de los servicios de atención sanitaria redunda en diferencias cada vez mayores en el estado de salud de una población, y en una "brecha de salud" que se ensancha progresivamente entre pobres y ricos. Demostramos que la situación de salud del Perú ilustra todas las características del modelo de transición polarizada y prolongada, que es una variante del modelo de transición no occidental y que explica este proceso de polarización epidemiológica. Para hacerle frente a la triple carga de morbilidad y la polarización epidemiológica en el Perú, es necesario distribuir más uniformemente el desarrollo social y económico, procurando reducir la brecha entre ricos y pobres en lo referente a algunos factores determinantes destacados (por ej., el ingreso, la educación, la nutrición y los servicios de salud). Todo esto se conseguirá solo mediante grandes inversiones en la salud pública, la adopción de un enfoque integral por el Gobierno peruano, y el completo compromiso del Ministerio de Salud y de los formuladores de las políticas de salud y de otras área

A future without health? Health dimension in global scenario studies.

This paper reviews the health dimension and sociocultural, economic, and ecological determinants of health in existing global scenario studies. Not even half of the 31 scenarios reviewed gave a good description of future health developments and the different scenario studies did not handle health in a consistent way. Most of the global driving forces of health are addressed adequately in the selected scenarios, however, and it therefore would have been possible to describe the future developments in health as an outcome of these multiple driving forces. To provide examples on how future health can be incorporated in existing scenarios, we linked the sociocultural, economic, and environmental developments described in three sets of scenarios (special report on emission scenarios (SRES), global environmental outlook-3 (GEO3), and world water scenarios (WWS)) to three potential, but imaginary, health futures ("age of emerging infectious diseases", "age of medical technology", and "age of sustained health"). This paper provides useful insights into how to deal with future health in scenarios and shows that a comprehensive picture of future health evolves when all important driving forces and pressures are taken into account.
