The impacts of global environmental change have precipitated numerous approaches that connect the health of ecosystems, non-human organisms and humans. However, the proliferation of approaches can lead to confusion due to overlaps in terminology, ideas and foci. Recognising the need for clarity, this paper provides a guide to seven field developments in environmental public health research and practice: occupational and environmental health; political ecology of health; environmental justice; ecohealth; One Health; ecological public health; and planetary health. Field developments are defined in terms of their uniqueness from one another, are historically situated, and core texts or journals are highlighted. The paper ends by discussing some of the intersecting features across field developments, and considers opportunities created through such convergence. This field guide will be useful for those seeking to build a next generation of integrative research, policy, education and action that is equipped to respond to current health and sustainability challenges.

Background Patient advocates are increasingly authoring peer-reviewed publications that could enhance patient care and understanding of the lived experience. Although patient authorship may be seen as an innovation in the peer-reviewed publication environment and some may not be aware of or accept patient authorship, we know patient-authored publications exist. However, identifying patient-authored publications is often challenging and time-consuming. Main body In this commentary, we propose a definition for a patient author and patient-authored publications. We outline factors driving the increase in patient authorship, including patient interest, recognition of the value of including the patient voice and major funders recognising the importance of involving patient advocates in research. Evidence and experience-based guidance on patient authorship is emerging, and we highlight practical guidance for patient advocates on authoring peer-reviewed publications. To gain a better understanding of patient authorship, an efficient method is needed to identify patient-authored publications. A dataset on patient-authored publications could be used for a range of quantitative and qualitative research studies. The affiliation search function in PubMed can provide an easy, and reproducible way to identify a dataset of patient-authored publications in the international peer-reviewed literature, but only if patient authors include a standard metatag, (e.g. Patient Author) as one of their listed affiliations, combined with other affiliations as appropriate. From 2020 to 2021, there was a nine-fold increase in patient-authored publications in PubMed identified using the Patient Author tag. We recognize that terminology can be contentious and some authors may prefer alternative metatags. Further efforts are required to gain consensus on a suitable, standard metatag or set of metatags to use to show the true extent of patient authorship. Conclusion Patient authorship is not only legitimate, but it also exemplifies the principles of diversity, equity and inclusion. Stakeholders in the publication community need to review their policies and procedures to identify and address barriers to patient authorship. Patient advocates, funders, researchers and publishers could all help to promote awareness and acceptance of patient authorship and the merits of using a standard metatag or set of metatags, so that patient-authored publications are no longer hidden in plain sight.

Future Science Group (FSG) is keen to recognize and promote the vital role of patients in medical and scientific research, and as such, has introduced a new article type to its collection -the Plain

Plain language summaries (PLS) are accessible, short, peerreviewed summaries of scholarly journal articles written in nontechnical language.• The aim of PLS is to enable a broader audience of experts and non-experts to understand the original article.• Here, we outline the evidence base for the value and impact of PLS and how they can enable diversity, equity, inclusion and accessibility in scholarly publishing.• PLS can diversify readership and authorship, address information inequity, include typically under-represented stakeholders and provide an accessible route into scholarly literature.
