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.

[Training modules on climate change, heat, and health for medical assistants and nurses in outpatient care]. / Fortbildungsangebote zu Klimawandel, Hitze und Gesundheit für medizinische Fachangestellte und Pflegefachkräfte in der ambulanten Versorgung.

The number of heatwaves is going to increase due to climate change and will pose a high health risk especially for elderly people. Additional risk factors like immobility, the need for care, chronic and acute diseases (worsening of symptoms), and the intake of medications lead to an increased sensitivity to heat in this particular age group. Nursing staff and medical assistants working in general practices are two important professions to reach the risk group during heatwaves and provide preventive and curative care.The "Klinikum der Universität München" has developed an interprofessional blended-learning program to sensitize for this topic and to enable those two professional groups to react adequately to heat events. It combines independent learning with the help of online videos and presentations and a face-to-face component for the practical application of knowledge through examples. The concept, the results, as well as the conclusion of the project, which completed in October 2018, are presented in this article.Educational programs are part of the adaption strategies to heat events. The "Recommendations for the creation of Heat Action Plans for the Protection of Human Health" state that advanced trainings and education of healthcare and social workers help to communicate relevant content to adequately act during heat periods. The developed educational program fulfills this demand.To enable the widest possible use, the training materials are available free of charge and can be downloaded from www.klimawandelundbildung.de .

Biomarkers of exposure in environment-wide association studies - Opportunities to decode the exposome using human biomonitoring data.

BACKGROUND: The European Union's 7th Framework Programme (EU's FP7) project HEALS - Health and Environment-wide Associations based on Large Population Surveys - aims a refinement of the methodology to elucidate the human exposome. Human biomonitoring (HBM) provides a valuable tool for understanding the magnitude of human exposure from all pathways and sources. However, availability of specific biomarkers of exposure (BoE) is limited. OBJECTIVES: The objective was to summarize the availability of BoEs for a broad range of environmental stressors and exposure determinants and corresponding reference and exposure limit values and biomonitoring equivalents useful for unraveling the exposome using the framework of environment-wide association studies (EWAS). METHODS: In a face-to-face group discussion, scope, content, and structure of the HEALS deliverable "Guidelines for appropriate BoE selection for EWAS studies" were determined. An expert-driven, distributed, narrative review process involving around 30 individuals of the HEALS consortium made it possible to include extensive information targeted towards the specific characteristics of various environmental stressors and exposure determinants. From the resulting 265 page report, targeted information about BoE, corresponding reference values (e.g., 95th percentile or measures of central tendency), exposure limit values (e.g., the German HBM I and II values) and biomonitoring equivalents (BEs) were summarized and updated. RESULTS: 64 individual biological, chemical, physical, psychological and social environmental stressors or exposure determinants were included to fulfil the requirements of EWAS. The list of available BoEs is extensive with a number of 135; however, 12 of the stressors and exposure determinants considered do not leave any measurable specific substance in accessible body specimens. Opportunities to estimate the internal exposure stressors not (yet) detectable in human specimens were discussed. CONCLUSIONS: Data about internal exposures are useful to decode the exposome. The paper provides extensive information for EWAS. Information included serves as a guideline - snapshot in time without any claim to comprehensiveness - to interpret HBM data and offers opportunities to collect information about the internal exposure of stressors if no specific BoE is available.

Exploring pathways linking greenspace to health: Theoretical and methodological guidance.

BACKGROUND: In a rapidly urbanizing world, many people have little contact with natural environments, which may affect health and well-being. Existing reviews generally conclude that residential greenspace is beneficial to health. However, the processes generating these benefits and how they can be best promoted remain unclear. OBJECTIVES: During an Expert Workshop held in September 2016, the evidence linking greenspace and health was reviewed from a transdisciplinary standpoint, with a particular focus on potential underlying biopsychosocial pathways and how these can be explored and organized to support policy-relevant population health research. DISCUSSIONS: Potential pathways linking greenspace to health are here presented in three domains, which emphasize three general functions of greenspace: reducing harm (e.g. reducing exposure to air pollution, noise and heat), restoring capacities (e.g. attention restoration and physiological stress recovery) and building capacities (e.g. encouraging physical activity and facilitating social cohesion). Interrelations between among the three domains are also noted. Among several recommendations, future studies should: use greenspace and behavioural measures that are relevant to hypothesized pathways; include assessment of presence, access and use of greenspace; use longitudinal, interventional and (quasi)experimental study designs to assess causation; and include low and middle income countries given their absence in the existing literature. Cultural, climatic, geographic and other contextual factors also need further consideration. CONCLUSIONS: While the existing evidence affirms beneficial impacts of greenspace on health, much remains to be learned about the specific pathways and functional form of such relationships, and how these may vary by context, population groups and health outcomes. This Report provides guidance for further epidemiological research with the goal of creating new evidence upon which to develop policy recommendations.

[Climate change and child health: A nationwide survey among paediatricians in Germany]. / Klimawandel und Kindergesundheit: eine bundesweite Befragung von Pädiater*innen in Deutschland.

BACKGROUND: Children are a vulnerable group affected by climate change. Paediatricians are important actors in protecting children from climate change-related health risks and in identifying and treating relevant health effects. The main objectives of this study were to determine how paediatricians assess the relevance of climate change-related health impacts, through which channels paediatricians can be reached most effectively, how often climate change-specific prevention measures are implemented and how they are assessed. METHODS: Between February and July 2020, an online survey was conducted among paediatricians. The cross-sectional survey was designed to gather knowledge and attitudes about the relevance of climate change, sources of information and prevention measures. All participants who answered only one question or none at all were excluded. Differences between groups were determined using one-factorial analysis of variance. Correlations were determined using Pearson's bivariate correlation analysis and tested for two-sided significance. RESULTS: A total of 408 questionnaires were analysed. Over 95% of the respondents were paediatricians, with just under half of them working in children's hospitals and a good third in paediatric practices. According to paediatricians, climate change has a relevant impact on children's health. The most significant effects on children's health were considered to be longer and stronger pollen seasons, neophytes and neozoa, Lyme disease and TBE (tick-borne encephalitis, summer meningoencephalitis), UV radiation and air pollutants. Certified training options in professional journals and participation in lectures or workshops at relevant congresses were identified as the two preferred types of training. Especially professional journals as the most frequently used source of information could function as a suitable tool to reach as many paediatricians as possible. 76% of the paediatricians have not yet carried out any corresponding prevention activities, although information activities for parents or children were seen as being effective by 80%. Whereas the possibilities of integrating climate change-oriented prevention activities into everyday practice, were perceived less positively. The most frequent reason given was lack of time. DISCUSSION: To satisfy this future need for knowledge, but also for offerings from paediatricians for patients and their parents, concrete further continuous education and consultancy services must be prepared. In the future, further training offers, including the consultancy services, should be integrated into profession-specific training modules, presented at congresses, and then implemented into paediatricians' daily routine. CONCLUSION: The results of the study illustrate that the topic "climate change and health" has a high relevance for paediatricians and that information measures for parents are considered to be effective. Although paediatricians are concerned with the topic, there is an implementation deficit. Support is needed in the form of intensifying awareness-raising projects and educational modules for paediatricians to move from knowledge to action.

Hot days and Covid-19: Online survey of nurses and nursing assistants to assess occupational heat stress in Germany during summer 2020.

Objectives: Our aim was to identify if working during hot days while wearing Covid-19 related personal protective equipment causes occupational heat stress for nurses and nursing assistants in Germany. Design: Using an online survey, we assessed the impact of hot weather on nurses and nursing assistants working with personal protective equipment. Respondents were recruited by distributing the link to the survey via personal communication, email and various social media channels to nursing staff from hospitals, nursing homes and outpatient care. Results: There were in total 428 participants (18.2% male, 82.5% female), mostly (30.5%) aged between 45 and 55 years. Half of respondents (48.3%) had more than 20 years of experience in nursing. Cardiac, pulmonary, or other pre-existing conditions were reported by 46.2%.Nurses and nursing assistants working in personal protective equipment during hot days were exposed to occupational heat stress. Work was found exhaustive by 96.5% of the participants during those days. 93.0% reported breathing problems and 85.8% reported difficulties with focusing on their work. Many workplaces did not provide adequate heat protection, with distinct differences concerning the amount of prophylactic and heat mitigating measures across institutions. There were significant differences across institutions when it comes to the number of drinks served (p < 0.001), the availability of room thermometers (p < 0.001), the use of mobile cooling devices (p < 0.001) and fans (p < 0.05). Conclusions: Results suggest employers must make more of an effort to provide adequate heat protection for their nursing staff. In order to ensure patient care, there is a need for action; in particular, attention must be paid to the pre-existing health conditions of the nursing staff.
