Erste Ergebnisse

ZusammenfassungAntipsychotika haben sich in der Langzeitbehandlung schizophren erkrankter Patienten als sehr effektiv erwiesen. Dennoch bedarf es weiterer Forschung, um die medikamentöse Langzeitbehandlung, insbesondere bei ersterkrankten schizophrenen Patienten zu optimieren. Unter dieser Zielsetzung wurde eine multizentrische klinische Studie im Rahmen des Kompetenznetzes Schizophrenie durchgeführt, die zwei Hauptfragestellungen untersucht: Gibt es Unterschiede in der Rezidivrate a) der postakuten einjährigen Erhaltungsmedikation mit einem niedrigdosierten typischen versus atypischen Antipsychotikum und b) anschließendem Fortführen versus Absetzen der neuroleptischen Medikation, jeweils ergänzt durch prodromgestützte Frühintervention. Erste Ergebnisse der abgeschlossenen Studie sprechen für eine rezidivprophylaktische Effektivität beider Neuroleptika bei einer hohen Abbruchquote. Dies verweist auf einen Bedarf an speziellen Programmen, um (ersterkrankte) schizophrene Patienten in der effektiven Behandlung zu halten. Entsprechend werden in einer Transfer-Phase Informations-und Fortbildungsmaterialien entwickelt, die zu einer verbesserten Versorgung ersterkrankter Patienten beitragen sollen.

Abstract Background Typical gait is often considered to be highly symmetrical, with gait asymmetries typically associated with pathological gait. Whilst gait symmetry is often expressed in symmetry ratios, measures of symmetry do not provide insight into how these asymmetries affect gait variables. To fully understand changes caused by gait asymmetry, we must first develop a normative database for comparison. Therefore, the aim of this study was to describe normative reference values of regional plantar load and present comparisons with two pathological case studies. Methods A descriptive study of the load transfer of plantar pressures in typically developed children was conducted to develop a baseline for comparison of the effects of gait asymmetry in paediatric clinical populations. Plantar load and 3D kinematic data was collected for 17 typically developed participants with a mean age of 9.4 ± 4.0 years. Two case studies were also included; a 10-year-old male with clubfoot and an 8-year-old female with a flatfoot deformity. Data was analysed using a kinematics-pressure integration technique for anatomical masking into 5 regions of interest; medial and lateral forefoot, midfoot, and medial and lateral hindfoot. Results Clear differences between the two case studies and the typical dataset were seen for the load transfer phase of gait. For case study one, lateral bias was seen in the forefoot of the trailing foot across all variables, as well as increases in contact area, force and mean pressure in the lateral hindfoot of the leading foot. For case study two, the forefoot of the trailing foot produced results very similar to the typical dataset across all variables. In the hindfoot of the leading foot, medial bias presents most notably in the force and mean pressure graphs. Conclusions This study highlights the clinical significance of the load transfer phase of gait, providing meaningful information for intervention planning.

AbstractWe present electric field measurements and imaging of a Yagi–Uda antenna near-field using a Rydberg atom–based radio frequency electric field measurement instrument. The instrument uses electromagnetically induced transparency with Rydberg states of cesium atoms in a room-temperature vapor and off-resonant RF-field–induced Rydberg-level shifts for optical SI-traceable measurements of RF electric fields over a wide amplitude and frequency range. The electric field along the antenna boresight is measured using the atomic probe at a spatial resolution of ${\lambda }_{RF}/2$ with electric field measurement uncertainties below 5.5%, an improvement to RF measurement uncertainties provided by existing antenna standards.
