Abstract
The trinuclear copper(ii) complex [Cu3(saltag)(py)6]ClO4 (H5saltag = tris(2-hydroxybenzylidene)triaminoguanidine) was synthesized and characterized by experimental as well as theoretical methods. This complex exhibits a strong antiferromagnetic coupling (J = -298 cm-1) between the copper(ii) ions, mediated by the N-N diazine bridges of the tritopic ligand, leading to a spin-frustrated system. This compound shows a T2 coherence time of 340 ns in frozen pyridine solution, which extends to 591 ns by changing the solvent to pyridine-d5. Hence, the presented compound is a promising candidate as a building block for molecular spintronics.

Abstract
Mainly because of the large number of people affected and associated significant health policy implications, the Robert Koch Institute (RKI) is developing a public health surveillance system using diabetes as an example. In a first step to ensure long-term and comparable data collection and establish efficient surveillance structures, the RKI has defined a set of relevant indicators for diabetes surveillance. An extensive review of the available literature followed by a structured process of consensus provided the basis for a harmonised set of 30 core and 10 supplementary indicators. They correspond to the following four fields of activity: (1) reducing diabetes risk, (2) improving diabetes early detection and treatment, (3) reducing diabetes complications, (4) reducing the disease burden and overall costs of the disease. In future, in addition to the primary data provided by RKI health monitoring diabetes surveillance needs to also consider the results from secondary data sources. Currently, barriers to accessing this data remain, which will have to be overcome, and gaps in the data closed. The RKI intentends to continuously update this set of indicators and at some point apply it also to further chronic diseases with high public health relevance.

Abstract
BACKGROUND Published studies on community-acquired urinary tract infections (UTI) often do not link microbiological findings with clinical risk factors and patient data. MATERIALS AND METHODS We retrospectively correlated clinical findings of all patients with UTI of a urological outpatient clinic with the respective microbiological analysis of their urine samples over 2 periods of time: (A: 2005-2006 and B: 2011-2012). Patients were stratified to the following risk groups: uncomplicated cystitis, diabetes mellitus type 2, nursing home resident, prostatitis/epidydimitis, permanent catheter. RESULTS The incidence of Escherichia coli (p < 0.001) and proteus (p < 0.001) significantly decreased from period A to B, while enterococci (p = 0.003) and staphylococci (p < 0.001) significantly increased. Antibiotic sensitivity to fosfomycin (p < 0.001), doxycycline (p < 0.001), nitrofurantoin (p < 0.001), and nitroxoline increased (p < 0. 001) and sensitivity to amoxicillin (p < 0.001) and gentamicin decreased (p < 0.001). Patients with a permanent catheter had significantly poorer sensitivity rates (50% and less) for almost all antibiotics tested compared to the overall group. The risk of a UTI with 3MRGN or MRSA bacteria was significantly higher for catheter carriers and nursing home residents. CONCLUSIONS Empiric antibiotic first-line therapy with nitrofurantoin and fosfomycin for uncomplicated community acquired UTIs are well indicated in conformity with guidelines. The accumulation of multiresistant pathogens in patients with a permanent bladder catheter requires restrictive use of any permanent catheter drainage.

Abstract
BACKGROUND The introduction and approval of Ocriplasmin as an intravitreally applicable drug in the pharmocological treatment of vitreomacular traction represents a new therapeutic approach possibly avoiding vitreoretinal surgery. With our article we report our first experience wih Ocriplasmin in clinical practice. METHODS The indication for intravitreal therapy with Ocriplasmin was provided for symptomatic VMT or macular hole with VMT in 20 patients since March 2013. Surgery was planned in cases with remaining symptoms. Before IVI we performed SD-OCT. Best visual acuity (BCVA) was evaluated preoperatively, 7 and 28 days after treatment and finally every month in 14 treated eyes. SD-OCT images were analysed before treatment and later on with every follow-up examination. In addition to functional and morphological changes we analysed all side effects. RESULTS The mean BCVA at the beginning of treatment was 0.3 and 0.4 before injection. The indications for treatment were as follows: symptomatic VMT in 10 patients and 4 patients suffering from full thickness macular hole stage 2. In 3 patients spontaneous regression of VMT could be observed with increasing of vision from 0.3 to 0.5. In one patient his macular hole was closed and BCVA increased from 0.2 to 0.6 within 7 days. Two patients showed significant enlargement of their macular holes after 7 days and finally underwent surgery. A massive cystoid macular oedema occurred in one patient. No change in the SD-OCT image could be observed 28 days after treatment. The mean visual acuity improved to 0.6 during a follow-up period of 90 days. Photopsia and disturbing vitreous opacities up to 28 days post injection could be regarded as minor side effects. CONCLUSION Our first clinical experience with intravitreous injection of Ocriplasmin were performed to confirm the presumed therapeutic effect in patients suffering from VMT. Small macular holes could frequently be closed. The possibility of special side effects must be taken in consideration just as the possibility of spanteous improvement before performing IVI with Ocriplasmin. Further prospective studies must be recommended to be right about Ocriplasmin injections.

Abstract
This study compares electrocommunication behaviour in groups of freely swimming weakly electric fishes of two species, Marcusenius altisambesi and Mormyrus rume. Animals emitted variable temporal sequences of stereotyped electric organ discharges (EOD) that served as communication signals. While the waveform of individual signals remained constant, the inter-discharge interval (IDI) patterns conveyed situation-specific information. Both species showed different types of group behaviour, e.g. they engaged in collective (group) foraging. The results show that in each species, during different behavioural conditions (resting, foraging and agonistic encounters), certain situation-specific IDI patterns occurred. In both species, neighbouring fishes swimming closely together interacted electrically by going in and out of synchronization episodes, i.e. periods of temporally correlated EOD production. These often resulted in echo responses between neighbours. During group foraging, fishes often signalled in a repetitive fixed order (fixed-order signalling). During foraging, EOD emission rates of M. altisambesi were higher and more regular than those of M. rume. The two species also differed in the quantity of group behaviours with M. altisambesi being more social than M. rume, which was reflected in the lack of specific agonistic IDI patterns, more fixed-order signalling and more communal resting behaviour in M. altisambesi.
