- Background: A recent dialogue in the field of play, learn, and teach outdoors (referred to as “PLaTO” hereafter) demonstrated the need for developing harmonized and consensus-based terminology, taxonomy, and ontology for PLaTO. This is important as the field evolves and diversifies in its approaches, contents, and contexts over time and in different countries, cultures, and settings. Within this paper, we report the systematic and iterative processes undertaken to achieve this objective, which has built on the creation of the global PLaTO-Network (PLaTO-Net). Methods: This project comprised of four major methodological phases. First, a systematic scoping review was conducted to identify common terms and definitions used pertaining to PLaTO. Second, based on the results of the scoping review, a draft set of key terms, taxonomy, and ontology were developed, and shared with PLaTO members, who provided feedback via four rounds of consultation. Third, PLaTO terminology, taxonomy, and ontology were then finalized based on the feedback received from 50 international PLaTO member participants who responded to ≥ 3 rounds of the consultation survey and dialogue. Finally, efforts to share and disseminate project outcomes were made through different online platforms. Results: This paper presents the final definitions and taxonomy of 31 PLaTO terms along with the PLaTO-Net ontology model. The model incorporates other relevant concepts in recognition that all the aspects of the model are interrelated and interconnected. The final terminology, taxonomy, and ontology are intended to be applicable to, and relevant for, all people encompassing various identities (e.g., age, gender, culture, ethnicity, ability). Conclusions: This project contributes to advancing PLaTO-based research and facilitating intersectoral and interdisciplinary collaboration, with the long-term goal of fostering and strengthening PLaTO’s synergistic linkages with healthy living, environmental stewardship, climate action, and planetary health agendas. Notably, PLaTO terminology, taxonomy and ontology will continue to evolve, and PLaTO-Net is committed to advancing and periodically updating harmonized knowledge and understanding in the vast and interrelated areas of PLaTO.

- Neisseria meningitidis is often asymptomatically carried in the nasopharynx but may cause invasive meningococcal disease, leading to morbidity and mortality. Meningococcal conjugate vaccinations induce functional protective antibodies against capsular antigens, but seroprotection wanes over time. We measured functional antibody titers five years after administration of a single dose of the meningococcal ACWY-polysaccharide-specific tetanus toxoid-conjugated (MenACWY-TT) vaccine in adolescents and middle-aged adults in the Netherlands, using the serum bactericidal antibody with baby rabbit complement (rSBA) assay. Protection was defined as rSBA titer >= 8. The meningococcal ACWY-specific serum IgG concentrations were measured with a multiplex immunoassay. Duration of protection was estimated by a bi-exponential decay model. Sufficient protection for MenC, MenW, and MenY was achieved in 94-96% of the adolescents five years postvaccination, but, in middle-aged adults, only in 32% for MenC, 65% for MenW and 71% for MenY. Median duration of protection for MenCWY was 4, 14, and 21 years, respectively, in middle-aged adults, while, in adolescents, it was 32, 98, and 33 years. Our findings suggest that adolescents, primed in early childhood with MenC conjugate vaccination, remain sufficiently protected after a single dose of MenACWY-TT vaccine. Middle-aged adults without priming vaccination show fast waning of antibodies, particularly MenC, for which protection is lost after four years.

- This synthesis report is a meta-analysis of perspectives for biodiversity and ecosystems, with a strong focus on human impacts on the environment, and a work order to enable and manage the protection, survival and evolution of all species on Earth. The goal is to protect nature without any further species loss (Zero Extinction). With this report, we assess alarming signals from the environment; determine the needs of threatened biota and the required actions to manage and protect landscapes and ecosystems; and identify some inescapable tendencies, challenges but also possibilities. The story of humans on Earth is at a critical juncture. Human behaviour is inherently dependent on physical and societal relations, including orientation and positioning within the physical environment. There is no single cultural benefit that is independent of provisioning through ecosystem services. Humans are part of the environment, acquire all needs from it and, as such, depend on its integrity and management for life and well-being. Moreover, if human impacts to the environment continue to increase the risk of rebound effects impacting human life and health will increase as well. Whenever a biome, ecosystem, habitat or species is heavily impacted or threatened with irreversible transformation or extinction, prevailing environmental conditions are relevant and should be observed, analysed and remedied as necessary and where possible. Ecology examines the evolutionary, historical and more recent interplay between biological life and the abiotic environment, while the role of social science and the humanities is to question the physical and social landscape, and how and why it should be protected or influenced, e.g. by nature conservation measures under political and economic, ethical and legal considerations. Thus, for all inter-relationships between natural and sociocultural processes, a joint venture in the form of social-ecological thinking is necessary to combine natural sciences and the humanities. With this contribution, we combine ecological knowledge with social science knowledge (s.l.) through the participation of scientists of many different disciplines. We analyse history and current processes to assess risks, threats and possibilities, and call for an array of regulations and measures that can contribute to halting of biodiversity loss and that assist in achieving a sustainable future. Regulations comprise creativity, cultural incentives, social norms, environmental education and economic investments—such as payments for sustainable agriculture, forestry, and fishery; investments in water, soil and air purity; and much clearer and stronger legal restrictions and consequences around waste streams and environmental degradation. Moreover, a gradual change from profit-oriented economies in the short-run to environmentally-sensitive policies that include systematic environmental programmes in the long term might help to decrease pressure on ecosystems and biota. Such economics might also include the real costs of consumerism, including the impacts of particular products on the environment and on human health. The greatest hurdle for the continued existence of many critically endangered species is the impact of widespread anthropogenic-driven change in the usage of water, air and land, and industry intensification in agriculture, aquaculture, forestry, urbanisation, transportation and mining sectors. However, there is not one simple solution to solve these issues. We conclude that many of the current developments have to be adjusted or gradually altered in a step-wise manner, especially with respect to existing sociocultural behaviours. Therefore, various concepts, decisions and measures should be discussed and implemented at all scales from local to supranational and among researchers, practitioners and politicians.

- Invariant natural killer T (iNKT) cells belong to the innate immune system and exercise a dual role as potent regulators of autoimmunity and participate in responses against different pathogens. They have been shown to prevent type 1 diabetes development and to promote antiviral responses. Many studies in the implication of environmental factors on the etiology of type 1 diabetes have suggested a link between enteroviral infections and the development of this disease. This study of the pancreatropic enterovirus Coxsackievirus B4 (CVB4) shows that although infection accelerated type 1 diabetes development in a subset of proinsulin 2–deficient NOD mice, the activation of iNKT cells by a specific agonist, α-galactosylceramide, at the time of infection inhibited the disease. Diabetes development was associated with the infiltration of pancreatic islets by inflammatory macrophages, producing high levels of interleukin (IL)-1β, IL-6, and tumor necrosis factor-α and activation of anti-islet T cells. On the contrary, macrophages infiltrating the islets after CVB4 infection and iNKT-cell stimulation expressed a number of suppressive enzymes, among which indoleamine 2,3-dioxygenase was sufficient to inhibit anti-islet T-cell response and to prevent diabetes. This study highlights the critical interaction between virus and the immune system in the acceleration or prevention of type 1 diabetes.

- Helminth parasites provoke multicellular immune responses in their hosts that can suppress concomitant disease. The gut lumen-dwelling tapeworm Hymenolepis diminuta, unlike other parasites assessed as helminth therapy, causes no host tissue damage while potently suppressing murine colitis. With the goal of harnessing the immunomodulatory capacity of infection with H. diminuta, we assessed the putative generation of anti-colitic regulatory B cells following H. diminuta infection. Splenic CD19(+) B cells isolated from mice infected 7 [HdBc(7(d))] and 14(d) (but not 3(d)) previously with H. diminuta and transferred to naive mice significantly reduced the severity of dinitrobenzene sulfonic acid (DNBS)-, oxazolone-, and dextran-sodium sulfate-induced colitis. Mechanistic studies with the DNBS model, revealed the anti-colitic HdBc(7(d)) was within the follicular B cell population and its phenotype was not dependent on IL-4 or IL-10. The HdBc(7(d)) were not characterized by increased expression of CD1d, CD5, CD23, or IL-10 production, but did spontaneously, and upon LPS plus anti-CD40 stimulation, produce more TGF-beta than CD19(+) B cells from controls. DNBS-induced colitis in RAG1(-/-) mice was inhibited by administration of HdBc(7(d)), indicating a lack of a requirement for T and B cells in the recipient; however, depletion of macrophages in recipient mice abrogated the anti-colitic effect of HdBc(7(d)). Thus, in response to H. diminuta, a putatively unique splenic CD19(+) B cell with a functional immunoregulatory program is generated that promotes the suppression of colitis dominated by TH1, TH2, or TH1-plus-TH2 events, and may do so via the synthesis of TGF-beta and the generation of, or cooperation with, a regulatory macrophage.
