Shared Rule in Federal Political Systems: Conceptual Lessons from Subnational Switzerland

This article reconceptualizes shared rule and uses novel data to measure it, thus addressing two shortcomings of federal literature. First, while most studies focus on self-rule, one question that is largely neglected is how lower-level governments can influence politics at a higher level in the absence of “second” chambers. The answer is through shared rule. A second shortcoming is that even when addressing this question, scholars concentrate on constitutional-administrative aspects of vertical intergovernmentalism, neglecting more informal, “political” dynamics. Comparing the twenty-six Swiss cantons allows drawing two lessons for federal studies: That shared rule is multifaceted and complex, and that to study informal territorial actors as well as direct political processes is indispensable to understand how power is actually distributed in federal political systems.

Lessons learned from the International Renal Cell Carcinoma-Venous Thrombus Consortium (IRCC-VTC)

Renal cell carcinoma (RCC) extension into the renal vein or the inferior vena cava occurs in 4%-10% of all kidney cancer cases. This entity shows a wide range of different clinical and surgical scenarios, making natural history and oncological outcomes variable and poorly characterized. Infrequency and variability make it necessary to share the experience from different institutions to properly analyze surgical outcomes in this setting. The International Renal Cell Carcinoma-Venous Tumor Thrombus Consortium was created to answer the questions generated by competing results from different retrospective studies in RCC with venous extension on current controversial topics. The aim of this article is to summarize the experience gained from the analysis of the world's largest cohort of patients in this unique setting to date.

Improved relapse-free survival after autologous stem cell transplantation does not translate into better quality of life in chronic lymphocytic leukemia: lessons from the randomized European Society for Blood and Marrow Transplantation-Intergroup study

In chronic lymphocytic leukemia (CLL) medical progress is driven by clinical studies with relapse-free survival (RFS) as the primary endpoint. The randomized EBMT-Intergroup trial compared high-dose therapy and autologous stem cell transplantation (ASCT) to observation and demonstrated a substantial improvement of RFS without showing improved overall survival for the transplant arm. Here we report quality of life (QoL) information of the first 3 years following randomization from that study. The main objective was to assess the impact of treatment on QoL over time. Two secondary analyses were performed to further investigate the impact of ASCT and relapse on QoL. In the primary analysis, we demonstrate an adverse impact of ASCT on QoL which was largest at 4 months and continued throughout the first year after randomization. Further, we demonstrated a sustained adverse impact of relapse on QoL which worsened over time. Despite better disease control by ASCT the side effects thus turned the net effect towards inferior QoL in the first year and comparable QoL in the following 2 years after randomization. This study emphasizes the importance of information concerning QoL impacts when patients are counseled about treatments aimed at improving RFS in the absence of a survival benefit.

„Lessons learned“ in der Revision von schriftlichen Prüfungs-Fragen

Fragestellung/Einleitung: Bisher existieren kaum Daten für den deutschsprachigen Raum, welche Fehler häufig bei der Erstellung von schriftlichen Prüfungsfragen gemacht werden. Diese Erkenntnisse könnten hilfreich sein, um Autoren in Schulungsworkshops mit dem Fokus auf die häufigsten Fehler zu schulen. Im vorliegenden Projekt wird der Frage nachgegangen, welche Fehler am häufigsten bei der Erstellung von schriftlichen Prüfungsfragen gemacht werden, und welche Schlussfolgerungen daraus für Autorenschulungen gezogen werden können. Methoden: Am Institut für Medizinische Lehre Bern werden die mit der inhaltlichen und/oder formalen Fragenrevision befassten MitarbeiterInnen (N=14) anhand von semi-strukturierten Interviews befragt, mit welcher Art von Mängeln sie bei den Fragen der von ihnen betreuten schriftlichen Prüfungen am häufigsten umgehen. Weiter wird erhoben, wie dem Revisionsbedarf aus ihrer Sicht in Schulungen am besten begegnet werden kann. Ergebnisse: Die vorläufigen Ergebnisse weisen darauf hin, dass in folgenden Bereichen am häufigsten Revisionsbedarf besteht: eindeutiger Focus auf ein konkretes Lernziel authentische und relevante Vignette für den Ausbildungsstand angemessener Schwierigkeitsgrad eindeutige Lösung formale und sprachliche Korrektheit Dementsprechend sollte auf diese Themenbereiche ein besonderer Schwerpunkt bei Schulungen gelegt werden. Diskussion/Schlussfolgerung: Die vorläufigen Ergebnisse weisen darauf hin, dass Mängel von schriftlichen Prüfungsfragen häufig in den Bereichen Focus, Vignette, Schwierigkeitsgrad, Eindeutigkeit und formal-sprachlichen Aspekten liegen. Autorenschulungen sollten diese Aspekte in den Vordergrund stellen. Unsere zum Zeitpunkt der GMA-Tagung vorliegenden definitiven Ergebnisse können dazu beitragen, Workshops zur Fragenerstellung noch besser am Schulungsbedarf auszurichten.

The swiss transplant cohort study: lessons from the first 6 years.

Prospective cohort studies significantly contribute to answering specific research questions in a defined population. Since 2008, the Swiss Transplant Cohort Study (STCS) systematically enrolled >95 % of all transplant recipients in Switzerland, collecting predefined data at determined time points. Designed as an open cohort, the STCS has included >3900 patients to date, with a median follow-up of 2.96 years (IQR 1.44-4.73). This review highlights some relevant findings in the field of transplant-associated infections gained by the STCS so far. Three key general aspects have crystallized: (i) Well-run cohort studies are a powerful tool to conduct genetic studies, which are crucially dependent on a meticulously described phenotype. (ii) Long-term real-life observations are adding a distinct layer of information that cannot be obtained during randomized studies. (iii) The systemic collection of data, close interdisciplinary collaboration, and continuous analysis of some key outcome data such as infectious diseases endpoints can improve patient care.

Conservation of threatened habitat types under future climate change – Lessons from plant-distribution models and current extinction trends in southern Germany

A higher risk of future range losses as a result of climate change is expected to be one of the main drivers of extinction trends in vascular plants occurring in habitat types of high conservation value. Nevertheless, the impact of the climate changes of the last 60 years on the current distribution and extinction patterns of plants is still largely unclear. We applied species distribution models to study the impact of environmental variables (climate, soil conditions, land cover, topography), on the current distribution of 18 vascular plant species characteristic of three threatened habitat types in southern Germany: (i) xero-thermophilous vegetation, (ii) mesophilous mountain grasslands (mountain hay meadows and matgrass communities), and (iii) wetland habitats (bogs, fens, and wet meadows). Climate and soil variables were the most important variables affecting plant distributions at a spatial level of 10 × 10 km. Extinction trends in our study area revealed that plant species which occur in wetland habitats faced higher extinction risks than those in xero-thermophilous vegetation, with the risk for species in mesophilous mountain grasslands being intermediary. For three plant species characteristic either of mesophilous mountain grasslands or wetland habitats we showed exemplarily that extinctions from 1950 to the present day have occurred at the edge of the species’ current climatic niche, indicating that climate change has likely been the main driver of extinction. This is largely consistent with current extinction trends reported in other studies. Our study indicates that the analysis of past extinctions is an appropriate means to assess the impact of climate change on species and that vulnerability to climate change is both species- and habitat-specific.

Genetic markers for stallion fertility - lessons from humans and mice

Our knowledge on the many aspects of mammalian reproduction in general and equine reproduction in particular has greatly increased during the last 15 years. Advances in the understanding of the physiology, cell biology, and biochemistry of reproduction have facilitated genetic analyses of fertility. Currently, there are more than 200 genes known that are involved in the production of fertile sperm cells. The completion of a number of mammalian genome projects will aid in the investigation of these genes in different species. Great progress has been made in the understanding of genetic aberrations that lead to male infertility. Additionally, the first genetic mechanisms are being discovered that contribute to the quantitative variation of fertility traits in fertile male animals. As artificial insemination (AI) represents a widespread technology in horse breeding, semen quality traits may eventually become an additional selection criterion for breeding stallions. Current research activities try to identify genetic markers that correlate to these semen quality traits. Here, we will review the current state of genetic research in male fertility and offer some perspectives for future research in horses.
