Translating Planetary Health Principles Into Sustainable Primary Care Services.

Global anthropogenic environmental degradations such as climate change are increasingly recognized as critical public health issues, on which human beings should urgently act in order to preserve sustainable conditions of living on Earth. "Planetary Health" is a breakthrough concept and emerging research field based on the recognition of the interdependent relationships between living organisms-both human and non-human-and their ecosystems. In that regards, there have been numerous calls by healthcare professionals for a greater recognition and adoption of Planetary Health perspective. At the same time, current Western healthcare systems are facing their limits when it comes to providing affordable, equitable and sustainable healthcare services. Furthermore, while hospital-centrism remains the dominant model of Western health systems, primary care and public health continue to be largely undervalued by policy makers. While healthcare services will have to adapt to the sanitary impacts of environmental degradations, they should also ambition to accompany and accelerate the societal transformations required to re-inscribe the functioning of human societies within planetary boundaries. The entire health system requires profound transformations to achieve this, with obviously a key role for public health. But we argue that the first line of care represented by primary care might also have an important role to play, with its holistic, interdisciplinary, and longitudinal approach to patients, strongly grounded in their living environments and communities. This will require however to redefine the roles, activities and organization of primary care actors to better integrate socio-environmental determinants of health, strengthen interprofessional collaborations, including non-medical collaborations and more generally develop new, environmentally-centered models of care. Furthermore, a planetary health perspective translated in primary care will require the strengthening of synergies between institutions and actors in the field of health and sustainability.

Talking about Climate Change and Environmental Degradation with Patients in Primary Care: A Cross-Sectional Survey on Knowledge, Potential Domains of Action and Points of View of General Practitioners.

PURPOSE: General practitioners (GPs) could play a role in mitigating climate change by raising awareness of its impact on human health and implementing changes to improve population health and decreasing environmental footprints. The aim of this study was to assess GPs' knowledge and perspectives about the health impacts of climate change. METHOD: A questionnaire was sent to 1972 GPs in the French-speaking part of Switzerland. Knowledge of the impact of environmental degradations and climate change on health and willingness to address climate change with patients, to be exemplary and to act as role models were surveyed as well as demographic characteristics of GPs. RESULTS: Respondents (N = 497) expressed a high level of self-reported knowledge regarding climate change, although it was lower for more specific topics, such as planetary health or health-environment co-benefits. Participants mostly agreed that it is necessary to adapt clinical practice to the health impacts of climate change and that they have a role in providing information on climate change and its links to human health. CONCLUSION: Most of the GPs were concerned about environmental and climate degradation. However, this study revealed a gap between the willingness of GPs to integrate the impact of climate change on health into their clinical activities and their lack of overall knowledge and scientific evidence on effective interventions. A promising way forward may be to develop co-benefit interventions adapted to the clinical setting on diet, active mobility and connecting with nature.

[Co-benefits of health promotion on global warming - The example of food and mobility]. / Cobénéfices de la promotion de la santé sur le réchauffement climatique - L'exemple de l'alimentation et de la mobilité.

Global warming is considered by most scientists as one of the greatest public health threats of the 21st century. Some individual behaviours and consumption habits related to the food and mobility sectors are responsible for a high amount of CO2 emissions, the main greenhouse gas. Thus, some messages promoted by health professionals will have an impact on the fight against the epidemic of lifestyle-related chronic diseases but will also have an environmental co-benefit. With a population increasingly aware of current environmental issues, environmental considerations could be an additional motivating factor for patients when promoting a healthier diet or physical activity.

Le réchauffement climatique est considéré par la majorité du monde scientifique comme une des plus grandes menaces de santé publique du 21e siècle. Certains comportements individuels et modes de consommation ayant trait aux secteurs de l'alimentation et de la mobilité sont à l'origine d'une quantité élevée d'émissions de gaz carbonique (C02), principal gaz à effet de serre. Ainsi, certains messages transmis par les professionnels qui œuvrent pour la promotion de la santé auront un impact sur la lutte contre l'épidémie de maladies chroniques liées au style de vie, mais auront également un cobénéfice environnemental. Dans une population de plus en plus sensibilisée aux enjeux écologiques actuels, les considérations environnementales pourraient être un facteur motivationnel supplémentaire chez les patients pour l'adoption d'un régime alimentaire plus sain ou d'une activité physique plus soutenue.

Rate and mechanism of the photoreduction of birnessite (MnO2) nanosheets.

The photoreductive dissolution of Mn(IV) oxide minerals in sunlit aquatic environments couples the Mn cycle to the oxidation of organic matter and fate of trace elements associated with Mn oxides, but the intrinsic rate and mechanism of mineral dissolution in the absence of organic electron donors is unknown. We investigated the photoreduction of δ-MnO2 nanosheets at pH 6.5 with Na or Ca as the interlayer cation under 400-nm light irradiation and quantified the yield and timescales of Mn(III) production. Our study of transient intermediate states using time-resolved optical and X-ray absorption spectroscopy showed key roles for chemically distinct Mn(III) species. The reaction pathway involves (i) formation of Jahn-Teller distorted Mn(III) sites in the octahedral sheet within 0.6 ps of photoexcitation; (ii) Mn(III) migration into the interlayer within 600 ps; and (iii) increased nanosheet stacking. We propose that irreversible Mn reduction is coupled to hole-scavenging by surface water molecules or hydroxyl groups, with associated radical formation. This work demonstrates the importance of direct MnO2 photoreduction in environmental processes and provides a framework to test new hypotheses regarding the role of organic molecules and metal species in photochemical reactions with Mn oxide phases. The timescales for the production and evolution of Mn(III) species and a catalytic role for interlayer Ca(2+) identified here from spectroscopic measurements can also guide the design of efficient Mn-based catalysts for water oxidation.
