Swiss Social Report: Generations in Perspective

Based on systematically prepared data and indicators, the Social Report 2012 informs about the current status and development trends in the Swiss society. This issue focuses on intergenerational relationships: How, for example, are intergenerational transfers carried out and what are they caused by? Does different cultural behaviour depend on the age group or do other social differences play a role? Do age-specific discriminations exist? Are young adults less politically involved than their parents? What impact has the demographic development of recent years had on the geographic structure? In addition to a selection of 75 indicators on these and other subjects, the Social Report contains five analytically oriented in-depth articles that are written from the perspective of the generational issue and which are dedicated to the following individual aspects: Equality of opportunities, cultural behaviour, age-specific discrimination, political involvement and the spatial reflection of the demographic changes. The Social Report 2012 is rooted in the tradition of the earlier issues of 2000, 2004 and 2008, which have been completely updated and supplemented with additional indicators. All the data are graphically presented and available in electronic form on this website. The five in-depth articles and all the short commentaries on the indicators were completely rewritten.

Cavovarus Foot Realignment to Treat Anteromedial Ankle Arthrosis

Background: Adult patients with cavovarus feet were seen with symptomatic anteromedial ankle arthrosis and, frequently, lateral hindfoot instability. Static and dynamic realignment was performed to redistribute joint contact pressures and restore stability. Methods: Thirteen patients with fixed cavovarus feet (6 neurogenic, 7 idiopathic; 6 with hindfoot instability, 7 without) and mild to moderate anteromedial ankle arthrosis were treated by osteotomies and tendon transfers but no lateral ligament reconstruction. Anteromedial cheilectomy of the ankle was added to increase dorsiflexion and alleviate anteromedial impingement. Results: Failure occurred in 2 patients, who required additional procedures. The remaining 11 patients improved from preoperative 45 to 71 points (American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scale score) at the latest follow-up (average 84 months). Ankle dorsiflexion improved 7 degrees on average. There was no recurrent hindfoot instability and no progression of anteromedial ankle arthrosis over time. Conclusion: Cavovarus foot realignment with anteromedial ankle cheilectomy reliably improved patients’ symptoms related to ankle arthrosis, restored lateral hindfoot stability, and stabilized the extent of anteromedial ankle arthrosis when talar varus tilt was reduced. Level of Evidence: Level IV, retrospective case series.

Risk adjustment in aging societies

Background In Switzerland, age is the predominant driver of solidarity transfers in risk adjustment (RA). Concerns have been voiced regarding growing imbalances in cost sharing between young and old insured due to demographic changes (larger fraction of elderly >65 years and rise in average age). Particularly young adults aged 19–25 with limited incomes have to shoulder increasing solidarity burdens. Between 1996 and 2011, monthly intergenerational solidarity payments for young adults have doubled from CHF 87 to CHF 182, which corresponds to the highest absolute transfer increase of all age groups. Results By constructing models for age-specific RA growth and for calculating the lifetime sum of RA transfers we investigated the causes and consequences of demographic changes on RA payments. The models suggest that the main driver for RA increases in the past was below average health care expenditure (HCE) growth in young adults, which was only half as high (average 2% per year) compared with older adults (average 4% per year). Shifts in age group distributions were only accountable for 2% of the CHF 95 rise in RA payments. Despite rising risk adjustment debts for young insured the balance of lifetime transfers remains positive as long as HCE growth rates are greater than the discount rate used in this model (3%). Moreover, the life-cycle model predicts that the lifetime rate of return on RA payments may even be further increased by demographic changes. Nevertheless, continued growth of RA contributions may overwhelm vulnerable age groups such as young adults. We therefore propose methods to limit the burden of social health insurance for specific age groups (e.g. young adults in Switzerland) by capping solidarity payments. Conclusions Taken together, our mathematical modelling framework helps to gain a better understanding of how demographic changes interact with risk adjustment and how redistribution of funds between age groups can be controlled without inducing further selection incentives. Those methods can help to construct more equitable systems of health financing in light of population aging.

The Territoriality of Fiscal Solidarity: Comparing Swiss Equalisation with European Union Structural Funding

This article theorises the territorial solidarity and fiscal federalism and compares Switzerland with the European Union. While inter-territorial solidarity is a prerequisite for legitimate fiscal equalisation, such equalisation in turn also contributes to the legitimacy of and solidarity within federal political systems. By cutting across territorial and ethno-national communities, fiscal transfers often contribute to both a “civic” sense of belonging and a “cosmopolitan” identity. After placing types and degrees of (inter-)territorial solidarity at the heart of our conceptual perspective, we discuss the effects of such solidarity through an analysis of two different forms of “federal” equalisation. Comparing the recently reformed Swiss fiscal equalisation system with the EU structural funds allows us to infer if, and how, the fiscal dimension of federalism matters for feelings of solidarity, reciprocity, unity and, ultimately, for the legitimacy of the very (nation-state or Union) structures that are to contribute to the ever-growing prosperity and happiness of their people(s). In Switzerland, a civic understanding of nationhood and cross-cutting cleavages were necessary conditions for extensive, effective and legitimate fiscal equalisation. We infer that, for the EU, this means that strengthening the equalisation component of the structural funds would contribute to an ever closer Union in a political sense: because fiscal equalisation and inter-territorial solidarity are interdependent, reinforcing the one also means cementing the other. Future studies of the EU and federal-type arrangements are advised to pay more explicit attention to the solidarity-element of territoriality – or the territoriality of (fiscal) solidarity.

Energy and charge transfer dynamics in DNA based light harvesting antennae

DNA can serve as a versatile scaffold for chromophore assemblies. For example, light-harvesting antennae have been realized by incorporating phenanthrene and pyrene building blocks into DNA strands. It was shown that by exciting at 320 nm (absorption of phenanthrene), an emission at 450 nm is observed which corresponds to a phenanthrene-pyrene exciplex. The more phenanthrenes are added into the DNA duplex, the higher is the fluorescence intensity with no significant change in quantum yield. This shows that phenanthrene acts as a donor and efficiently transfers the excitation energy to the pyrene. Up to now, the mechanism of this energy transfer and exciplex formation is not known. Therefore, we first aim at studying the photo-cycle of such DNA assemblies through transient absorption spectroscopy. Based on the results, we will explore ways to manipulate the energy transfer by application of intense THz fields. Ground as well as excited state Stark effect dynamics will be investigated.

Heterologous expression of equine CYP3A94 and investigation of a tunable system to regulate co-expressed NADPH P450 oxidoreductase levels.

The activity of cytochrome P450 enzymes depends on the enzyme NADPH P450 oxidoreductase (POR). The aim of this study was to investigate the activity of the equine CYP3A94 using a system that allows to regulate the POR protein levels in mammalian cells. CYP3A94 and the equine POR were heterologously expressed in V79 cells. In the system used, the POR protein regulation is based on a destabilizing domain (DD) that transfers its instability to a fused protein. The resulting fusion protein is therefore degraded by the ubiquitin-proteasome system (UPS). Addition of "Shield-1" prevents the DD fusion protein from degradation. The change of POR levels at different Shield-1 concentrations was demonstrated by cytochrome c reduction, Western immunoblot analysis, and immunocytochemistry. The alteration of CYP3A94 activity was investigated using a substrate (BFC) known to detect CYP3A4 activity. Equine CYP3A94 was demonstrated to be metabolically active and its activity could be significantly elevated by co-expression of POR. Cytochrome c reduction was significantly increased in V79-CYP3A94/DD-POR cells compared to V79-CYP3A94 cells. Surprisingly, incubation with different Shield-1 concentrations resulted in a decrease in POR protein shown by Western immunoblot analysis. Cytochrome c reduction did not change significantly, but the CYP3A94 activity decreased more than 4-fold after incubation with 500 nM and 1 µM Shield-1 for 24 hours. No differences were obtained when V79-CYP3A94 POR cells with and without Shield-1 were compared. The basal activity levels of V79-CYP3A94/DD-POR cells were unexpectedly high, indicating that DD/POR is not degraded without Shield-1. Shield-1 decreased POR protein levels and CYP3A94 activity suggesting that Shield-1 might impair POR activity by an unknown mechanism. Although regulation of POR with the pPTuner system could not be obtained, the cell line V79-CYP3A94/DD-POR system can be used for further experiments to characterize the equine CYP3A94 since the CYP activity was significantly enhanced with co-expressed POR.

On the Methyl-Transfer Reaction in Crystalline Methyl 2-(Methylthio)benzenesulfonate: a Thermally Induced Non-Topochemical Solid-State Reaction

The rearrangement of methyl 2-(methylthio)benzenesulfonate (1) to the zwitterionic 2-(dimethyl-sulfonium)benzenesulfonate (2) is known to proceed in solution by intermolecular Me transfers. The same rearrangement has been observed to occur in crystalline 1, but the crystal structure shows that the molecular packing is not conducive to intermolecular Me transfer. The reaction has been carried out with mixed crystals composed of 1 and deuteriomethylated (D6)-l. By fast-atom-bombardment mass spectroscopy, it has been shown that the product consists of a 1:2:1 mixture of the non-, tri-, and hexadeuterated species, the mixture expected, if the solid-state reaction proceeds by intermolecular Me transfers. From this result, together with the slower rates of conversion in the single crystal compared with the melt, it can be concluded that the reaction must occur not topochemically but rather at defects such as microcavities, surfaces, and other irregularities in the ordered crystal arrangement.

Demenzverdacht, aber normale neuropsychologische Screening-Untersuchung - wie weiter?

Die Demenz betrifft viele, belastet Angehörige und führt zu hohen Kosten, weshalb die Schweiz eine Sensibilisierungskampagne lancierte, um u.a. die Früherkennung der Demenz zu fördern. Dank der Früherkennung erleben Patienten und Angehörige Vorteile, wie weniger Notfallzuweisungen oder spätere Heimeintritte. Die Früherkennung ist aber schwierig, wenn Patienten zwar Gedächtnisprobleme beklagen, die Screening-Tests aber normal ausfallen. Möglicherweise helfen Geruchstests und weitere klinische Zeichen bei der Entscheidung, welche Patienten weiter abgeklärt werden. Die Zeit für funktionelle Bildgebungen und Biomarker ist noch nicht reif. Zentral bleibt bei kognitiven Beschwerden und normalem Screening das Gespräch mit Patient und Angehörigen, um nächste Schritte gemeinsam zu beschliessen. Der Hausarzt nimmt dabei eine zentrale, koordinierende und beratende Funktion ein, um Menschen mit Gedächtnisstörungen kompetent und effizient zu betreuen.

Die Schweiz anderswo - La Suisse ailleurs

Kurztext Gegenwärtig leben über 732 000 Schweizer Bürgerinnen und Bürger im Ausland, mehr als jede zehnte Person mit Schweizer Pass. Die Beiträge gehen den Fragen nach, inwiefern die erst seit dem 20. Jahrhundert so bezeichneten «Auslandschweizer» als wirtschaftliche «Brückenköpfe» dienten, inwiefern ihre kommunikativen Netzwerke kulturelle Transfers bewirkten und Formen des Wissensaustausches begünstigten oder welchen Beitrag umgekehrt die (ehemaligen) Auslandschweizerinnen und Auslandschweizer zu Wirtschaft, Wissenschaft, Sozialpolitik und Kultur in der Schweiz leisteten. Sie befassen sich aber auch mit der historischen Konstruktion der Bevölkerung als einer neuen politischen Kategorie. Nicht nur für die Neuzeit ist zu fragen, mit welchen Politiken und Massnahmen Obrigkeit, Behörden, Staat und Verwaltung die eigene Population konstituierten und festigten und sie je nachdem über die bestehenden (nationalstaatlichen) Grenzen hinweg ausdehnten. Plus de 732 000 citoyennes et citoyens suisses vivent actuellement à l’étranger, soit plus d’une personne sur dix titulaires du passeport helvétique. Les contributions rassemblées interrogent dans quelle mesure les «Suisses de l’étranger» – désignés ainsi à partir du 20e siècle seulement – ont servi de relais pour le commerce extérieur, ainsi que dans quelle mesure leurs réseaux de communication ont contribué aux transferts culturels et favorisé des formes d’échange du savoir ou, à l’inverse, quels sont les apports des (anciens) Suisses de l’étranger dans les domaines de l’économie, de la science, de la politique sociale et de la culture lors de leur retour en Suisse. Les contributions portent également sur la construction historique de la population en tant que nouvelle catégorie politique. La question de savoir à travers quelles politiques et mesures l’autorité, les pouvoirs publics, l’Etat et l’administration ont constitué et consolidé leur propre population et, suivant les cas, l’ont étendu au-delà des frontières (nationales) existantes concerne autant l’époque contemporaine que les périodes antérieures.
