Zeitgemäß oder anachronistisch? Zwangseinweisungspraxis in Frankfurt am Main

Background: The evaluation of local mental health care remains difficult. For this reason systematic development of appropriate services is barely possible. Methods: We examined involuntary hospitalization in the city of Frankfurt/Main with regard to diagnoses, socio-demographic data, complementary psychosocial outpatient care, and circumstances of hospitalization. There are four psychiatric clinics, each serving a catchment area of more than 165.000 inhabitants. These clinics are responsible for all psychiatric in-patient treatments regardless of the admission modus. During a one year period, 677 patients were involuntarily hospitalized. Statistical analyses were performed subsequent to pooling the data. Results: During a period of one year, 103 out of 100.000 inhabitants of Frankfurt/Main were admitted involuntarily. The rate of involuntary admissions related to all admissions was 10.98 percent. Any complementary psychosocial care was missing in more than 70 percent of patients admitted involuntarily. Only about 10 percent of patients were examined by a physician before reaching the hospital and in disappointing 1.3 percent the municipal mental health service had been consulted prior to involuntarily admission. Conclusion: Our results show that a systematic improvement of precautionary complementary psychosocial care for risk patients is needed as well as the obligation of psychiatric emergency consultation before involuntary hospitalization.Anliegen: In der gemeindepsychiatrischen Versorgung ist eine systematische Datenerhebung bislang unzureichend etabliert. Daher ist eine planvolle Entwicklung von Versorgungsstrukturen kaum möglich. Zur weiteren Qualitätsverbesserung der gemeindepsychiatrischen Struktur soll eine verlässliche Datenbasis geschaffen werden. Methode: Das durch den Sozialpsychiatrischen Dienst initiierte Projekt PISA untersuchte 677 Zwangseinweisungen in die Versorgungskliniken der Stadt Frankfurt/Main. Ergebnisse: Bei über 70 % der Patienten fehlte eine komplementäre psychosoziale Versorgung, nur 10 % wurden außerhalb der Klinik vor der Einweisung ärztlich untersucht, nur 1,3 % durch den Sozialpsychiatrischen Dienst. Schlussfolgerungen: Eine gezielte Ausweitung ambulanter Hilfesysteme und die Hinzuziehung fachärztlicher Kompetenz vor einer Zwangseinweisung erscheinen dringend erforderlich

Topologically protected edge states in small Rydberg systems

We propose a simple setup of Rydberg atoms in a honeycomb lattice which gives rise to topologically protected edge states. The proposal is based on the combination of dipolar exchange interaction, which couples the internal angular momentum and the orbital degree of freedom of a Rydberg excitation, and a static magnetic field breaking time reversal symmetry. We demonstrate that for realistic experimental parameters, signatures of topologically protected edge states are present in small systems with as few as 10 atoms. Our analysis paves the way for the experimental realization of Rydberg systems characterized by a topological invariant, providing a promising setup for future application in quantum information.Comment: 6 pages, 6 figure

Determination of residual stress in bonded wood components

Climate tests on double-layered samples were performed to detect deformation and induced stress concentrations. The paper is divided into two parts. The first presents experimental results for double-layered specimens. These specimens consisted of two wooden layers (each conditioned at a different climate before bonding) that were bonded using two different adhesives. The displacement field of the specimens was measured by means of digital fringe projection. The second part presents finite element results for two model stages using coupled thermal-mechanical analysis. For the first simple model, both orthotropic properties and the grain orientations were taken into account to investigate the behavior of the layers in principle. The results were compared to those for the experimental set-up. The improved second-stage model considers the adhesive layer between the wooden layers. The experimental and computational results of the improved simulation model are in good agreement. In the future, if inelastic material behavior is considered in a competitively superior manner, even better simulation results can be expecte
