Purpose: This paper presents the results of the first joint survey on the use of SPECT and PET myocardial perfusion imaging (MPI) and cardiac amyloidosis imaging in Austria, Germany, and Switzerland of the year 2021. Methods: A questionnaire was sent in 2022 to centres practicing nuclear medicine. Results: Data from 14 Austrian (10,710 SPECT), 218 German (133,047 SPECT), and 16 Swiss centres (11,601 MPI (6,879 SPECT, 4722 PET)) were analysed. In Austria and Germany, the PET MPI numbers were close to zero and not considered. Official MPS numbers from 2015 to 2021 from Austria and Germany revealed a decline in Austria by about 40% in the pandemic years 2020 to 2021, but an increase in Germany by 9%. Ambulatory care cardiologists represented the major referral group (56–71%). Mostly, stress tests were performed pharmacologically (58–92%). Contrary to Germany, a 1-day protocol was predominant (58–97%) in Austria and Switzerland. The leading camera systems were SPECT-CT in Austria and Switzerland (57–79%) and multi-head systems in Germany (58%). Switzerland had the highest proportion of SPECT MPI with attenuation correction (84%), followed by Austria (43%), and Germany (33%). Electrocardiogram-gated SPECT MPI showed an overall high penetration of 87–99%. Scoring was most frequently applied in Germany (72%), followed by Austria (64%), and Switzerland (60%). Related to the population, the number of cardiac amyloidosis imaging was highest in Austria, followed by Switzerland and Germany. Conclusions: This first joint survey of 2021 shows considerable differences among the countries. The Swiss situation is outstanding due to the wide use of PET MPI. In terms of camera equipment, Switzerland is also leading, followed by Austria and Germany. Despite the differences in procedural issues, the results reveal an overall high standard of MPI imaging.

Anisotropic fast-marching algorithms are computationally efficient tools for generating realistic maps of karst conduit networks, constrained by both the spatial extent and the orientation of karstifiable geologic units. Existing models to generate conduit network maps are limited either by high computational requirements (for chemistry-based models) or by their inability to incorporate the effects of elevation and orientation gradients (for isotropic fast-marching models). The new anisotropic fast-marching approach described here provides a significant improvement, though it imitates rather than reproduces actual speleogenetic processes. It can rapidly generate a stochastic ensemble of plausible networks from basic geologic information, which can also be used as input to karst-appropriate flow models. This paper introduces an open-source, easy-to-use implementation through the Python package pyKasso, then describes its application to a well-mapped geologically complex long-term study site: the Gottesacker alpine karst system (Germany/Austria). Groundwater flow in this system is exceptionally well understood from speleological investigations and tracer tests. Conduit formation primarily occurs at the base of the karst aquifer, following plunging synclines. Although previous attempts to reproduce the conduit network at this site yielded implausible network maps, pyKasso quickly generated networks faithful to the known conduit system. However, the model was only able to generate these realistic networks when the inlet-outlet connections of the system were correctly assigned, highlighting the importance of pairing modeling efforts with field tracer tests. Therefore, a model ensemble method is also presented, to optimize field efforts by identifying the most informative tracer tests to perform. [ABSTRACT FROM AUTHOR]

The paper reports the results of an exploratory online survey among German, Austrian, and Swiss hospital chaplains (n = 158, response rate 17%) to identify the ethical conflicts they encounter in their work. Respondents indicated that questions surrounding end-of-life care are predominant among the conflicts faced. Chaplains get involved with these conflicts most often through the patients themselves or through nursing staff. Most encounters occur during pastoral care visits rather than in structured forms of ethics consultation such as clinical ethics committees. The results add to the ongoing discussion of chaplains as agents in ethics consultation within healthcare systems as well as their specific role and contribution. [ABSTRACT FROM AUTHOR]

Relying on data collected by the Zurich Survey of Academics (ZSoA), a unique representative online survey among academics in Germany, Austria, and Switzerland (DACH region), this paper replicates Johann and Mayer's (Minerva 57(2):175–196, 2019) analysis of researchers' perceptions of scientific authorship and expands their scope. The primary goals of the study at hand are to learn more about (a) country differences in perceptions of scientific authorship, as well as (b) the influence of perceived publication pressure on authorship perceptions. The results indicate that academics in Switzerland interpret scientific authorship more leniently than their colleagues in Germany and Austria. The findings further indicate that, as perceived pressure to publish increases, researchers are more likely to belong to a group of academics who hold the view that any type of contribution/task justifies co-authorship, including even those contributions/tasks that do not justify co-authorship according to most authorship guidelines. In summary, the present study suggests that action is required to harmonize regulations for scientific authorship and to improve the research culture. [ABSTRACT FROM AUTHOR]

Egg freezing has led to heated debates in healthcare policy and bioethics. A crucial issue in this context concerns the distinction between "medical" and "social" egg freezing (MEF and SEF)—contrasting objections to bio-medicalization with claims for oversimplification. Yet such categorization remains a criterion for regulation. This paper aims to explore the "regulatory boundary-work" around the "medical"–"social" distinction in different egg freezing regulations. Based on systematic documents' analysis we present a cross-national comparison of the way the "medical"–"social" differentiation finds expression in regulatory frameworks in Austria, Germany, Israel, and the Netherlands. Findings are organized along two emerging themes: (1) the definition of MEF and its distinctiveness—highlighting regulatory differences in the clarity of the definition and in the medical indications used for creating it (less clear in Austria and Germany, detailed in Israel and the Netherlands); and (2) hierarchy of medical over social motivations reflected in usage and funding regulations. Blurred demarcation lines between "medical" and "social" are further discussed as representing a paradoxical inclusion of SEF while offering new insights into the complexity and normativity of this distinction. Finally, we draw conclusions for policymaking and the bioethical debate, also concerning the related cryopolitical aspects. [ABSTRACT FROM AUTHOR]

Background: Adolescent depression has been recognized as a complex problem that presents a global public health challenge. Left undetected and untreated, depression can significantly reduce quality of life. Objective: The main purpose of this paper is to re-visit risk and protective factors for depression in adolescents with a specific focus on exploring the individual, familial, and social contexts of depression (especially high and very high depression levels) in a multi-country sample of youth in order to see if these factors are mitigated by cultural location. Methods: Questionnaire data from a cross-sectional study of a randomly selected sample of 5149 middle-school students from four EU-countries (Austria, Germany, Slovenia, and Spain) was used. Applying variance analysis, we examined the prediction strength for the observed risk and protective factors. Results: In all participating countries we show that in for both male and female adolescents, depression is linked to a broad range of interactive individual, and social protective and risk factors, such that even if the contribution of a single factor is low but still significant and this factor's prediction strength is low or moderate, taken together, the cumulative prediction strength of these factors yields a remarkably similar coefficient of determination of 42-49% in all samples. Conclusions: We have established a significant and relevant combination of the individual and social multifactorial risk and protective factors that characterize depression in adolescents of both genders, no matter their country of location and with that, we call for a multifaceted and comprehensive approach to mental health assessment, prevention and intervention.
