With the steady increase in mean global temperature, the crossing of irreversible climate tipping points is becoming increasingly likely. There is a threat of a massive acceleration of biodiversity loss, acidification of the oceans, more frequent food shortages, an increase in extreme weather events, and climate-related refugee movements. As a compact “pocket book”, the Heidelberg standards of climate medicine provides broad knowledge, as well as practice-oriented recommendations for action on the scientific basics, the (medical) treatment of physical and psychological effects of the climate crisis, and the necessary transformation processes towards a more ecologically sustainable health sector. In 12 chapters with a total of 45 articles, the participating authors summarize the current state of research and information from their (medical) practice and provide useful tips and advice for the everyday professional life of all participants in the health sector. First, the Heidelberg standards of climate medicine provide a brief and concise overview of the scientific basics of the climate crisis (chapter 1) and their impact on natural and social systems (chapter 2). The knowledge of these basics will, on the one hand, help the reader with regard to the following book chapters, and, on the other hand, it should serve as a practical tool in (scientific) discourse. Two comprehensive chapters then highlight the numerous direct and indirect impacts of the climate crisis on human health. In the third chapter on the physical impacts of the climate crisis, it becomes evident how closely environmental changes (e.g., more frequent extreme weather events, heat waves, increased incidence of tropical pathogens) are linked to human health: The occurrence of many diseases, such as heat stroke, COPD, allergies, diabetes, or kidney failure, are influenced by the climate crisis. In addition to explaining this relationship, the chapter presents definitions relevant to clinicians, pathophysiological processes, key recommendations for clinical care, and helpful therapeutic strategies. The psychological effects of climate change are reflected upon in more detail in chapter 4, ranging from trauma in the context of natural disasters, to connections between climate, weather, and suicidality. Additionally, chapter 5 is dedicated to general cognitive processes and biases in psychological perceptions and processing of climate change. The discrepancy between knowledge and action regarding the climate crisis is also impressively illustrated. Subsequently, the Heidelberg standards of climate medicine reveals concrete fields of action in the health sector (including the reduction of emissions by means of changing the food supply, energymanagement, and drug supply in hospitals) in order to decisively counter the health crisis stemming from the climate crisis (chapter 6).

This is likely to come as a bit of a shock to anyone who has enjoyed watching Dr. House or is looking forward to a new episode of Adventure Diagnosis in the media library. However, Norbert Donner-Banzhoff manages the miracle of covering the entire spectrum of medical thought and action, including cognitive psychology and medical history perspectives, in order to explain this statement without once using the term clinical reasoning. Never before have I enjoyed reading about strategies for prevalence enrichment or regression to the mean so much, not tomention the excellent explanations and illustrations of the four-field table, where, after reading it, really no one can claim not to have understood it. And: the fact that tests only modify disease probabilities according to Bayes’ theoremand that the pre-test probability is decisive for this cannot be read often enough – so here also. For this is often forgotten in everyday clinical practice, as the author explains with striking and also somewhat frightening examples. Complete certainty can thus not be achieved in the always tricky contexts of diagnosing. Perhaps it would have been even more useful at these points for a better understanding of this fact not to speak of a disease being “ruled out” but rather of it being made “less likely” by a test. But this is whining on a high level. This book is not just a guide to making a medical diagnosis, it is much more than that. It offers insight into the daily work of physicians in the trickiest task and the greatest professional challenge: making (i.e., “making”) a diagnosis. In doing so, it is devoted to historical perspectives and scientific traditions of different countries that approach the diagnostic process in different ways. This offers an excellent opportunity to reflect on one's own medical work – and teaching – and to open up to sometimes painful insights. The author discusses how reference ranges come about and that biological fluctuations are the greatest source of uncertainty, as well as the overestimation of technical findings in everyday medical practice and the harmful consequences of overdiagnosis and overtreatment. Theoretical, partly philosophical passages explaining important background information on the status quo of medical diagnosis with its problematic consequences (“X-rays and injections are powerful rituals”) alternate with current practical references. These are strikingly accessible to those working in the medical field, students and teachers, and offer good starting points for reflecting on one’s own actions. It is very pleasant to note that, with very few exceptions, English terms have been translated into German. The chosen form of gendering – the female form is used everywhere, except when exclusively men are meant – keeps the text pleasantly readable, even if this principle weakens somewhat in some places toward the","PeriodicalId":45850,"journal":{"name":"GMS Journal for Medical Education","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42701841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Are his actions an expression of his primary motor cerebral cortex or do they reflect the intentions of a human individuality? How do we see? Are we passive recipients or do we have to actively shape our seeing? What results from approaching these questions by bringing together scientific and phenomenological-philosophical insights? Can guiding viewpoints for person-centeredmedicine be gained from this? These questions are illuminated comprehensively and in many ways in the newly published book “Wahrnehmen und Bewegen – Grundlagen einer allgemeinen Bewegungslehre” (Perceiving and Moving Foundations of a General Theory of Movement) by Friedrich Edelhäuser. In doing so, the author takes us to astonishing phenomena, to reflections worth considering, and to profound questions. Using the example of looking at a mountain landscape, the first phenomena of seeing are looked at: our gaze goes inwardly through the picture, searching for various objects and contours and arranging the details into a meaningful overall context. What at first appears to be fixed thus becomes experienceable as a process. In the “objectifying” view of physiology, vision is characterized as a process akin to a camera in which light passes through a lens onto the retina and then leads to electrochemical nervous processes. In this process, the qualitative perceptions melt down into a measurable but qualityless process. Vision thus becomes an example of the stimulus-response sequence, in which an external sensory stimulus becomes electrochemical processes inside, i.e. in the brain, and is answered with a reaction. Thereby not only the quality of the perceived disappears, but also the perceiving person. In the following, this socalled third-person-perspective as an objectifying approach is supplemented by introspection, the first-personperspective. In chapter 5 “perceiving and moving” the process of seeing is examined more closely. In doing so, one becomes aware of the fact that seeing includes an inner scanning of the contour to be perceived. This unconscious movement of the eyeballs can be represented technically and shows individual movement patterns, similar to gait or handwriting. If this movement is suppressed, the perceived blurs to a gray-in-gray for a short time due to the lack of contrast. During further analysis, it is noticeable that one is not only aligned to the object to be seen with one's eye muscles, but with one's entire head and body posture. Only this self-movementmakes seeing possible. Something similar can be shown for hearing and other sensory modalities. Looking back at the mountain landscape, it becomes clear that there is a circular relationship, the perception of the image and the contours that can be found in it are guiding the scanningmovements of the eye, which in turn are conditions for what is to be seen. Thus, there is no monocausal relationship with temporal succession, but a mutually dependent one.

It is the task of supervising physicians to make informal learning opportunities available to students when working with and on patients and to gradually transfer responsibility to them. Both students and physicians have a great need for information regarding the contextual conditions and didactic realization of this transfer of responsibility. Up to now, the faculties have only provided information and support in a sporadic manner and with little standardization. With MERLIN, the joint project undertaken by the Competence Network for Teaching Medicine in Baden-Württemberg, a platform for the final year was developed and released on the web.

Content and materials were compiled and structured based on a needs assessment. The first draft was evaluated by means of a simulation by students and then revised. A professional internet agency was involved for the technical implementation. The newly designed website <i>PJ-input</i> (\"PJ\" being the abbreviation for \"Praktisches Jahr\", the final year) contains areas for students and supervising physicians, as well as faculty-specific and general information about the final year. Faculty-specific content can be entered directly by the respective staff via an input mask and updated at any time. The provision of didactic materials can support competency-oriented teaching and learning in the final year. Here, for example, the concept of the Entrustable Professional Activities (EPA) was taken up, which gives students and supervising physicians orientation for the gradual assumption or transfer of responsibility. The platform was launched in spring 2021.

Increasing usage figures and the high frequency of use by students in the sections \"im PJ\" (during the final year) and \"nach dem PJ\" (after the final year) for the faculties involved in the MERLIN project confirm the target group-oriented design and use. The site should be promoted even more to pre-final-year students, as well as across state borders and to the target group of faculties.
