Currently, limited evidence is available regarding the regional impact and the outreach component of MTBs; (2) Methods: we analyzed MTB patient data from four neighboring Bavarian tertiary care oncology centers in W{\"u}rzburg, Erlangen, Regensburg, and Augsburg, together constituting the WERA Alliance. Absolute patient numbers and regional distribution across the WERA-wide catchment area were weighted with local population densities; (3) Results: the highest MTB patient numbers were found close to the four cancer centers. However, peaks in absolute patient numbers were also detected in more distant and rural areas. Moreover, weighting absolute numbers with local population density allowed for identifying so-called white spots—regions within our catchment that were relatively underrepresented in WERA MTBs; (4) Conclusions: investigating patient data from four neighboring cancer centers, we comprehensively assessed the regional impact of our MTBs. The results confirmed the success of existing collaborative structures with our regional partners. Additionally, our results help identifying potential white spots in providing precision oncology and help establishing a joint WERA-wide outreach strategy.}, language = {en} } @article{KressHuettenhoferLandryetal.2013, author = {Kress, Michaela and H{\"u}ttenhofer, Alexander and Landry, Marc and Kuner, Rohini and Favereaux, Alexandre and Greenberg, David and Bednarik, Josef and Heppenstall, Paul and Kronenberg, Florian and Malcangio, Marzia and Rittner, Heike and {\"U}{\c{c}}eyler, Nurcan and Trajanoski, Zlatko and Mouritzen, Peter and Birklein, Frank and Sommer, Claudia and Soreq, Hermona}, title = {microRNAs in nociceptive circuits as predictors of future clinical applications}, series = {Frontiers in Molecular Neuroscience}, volume = {6}, journal = {Frontiers in Molecular Neuroscience}, number = {33}, doi = {10.3389/fnmol.2013.00033}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-154597}, year = {2013}, abstract = {Neuro-immune alterations in the peripheral and central nervous system play a role in the pathophysiology of chronic pain, and non-coding RNAs - and microRNAs (miRNAs) in particular - regulate both immune and neuronal processes. Specifically, miRNAs control macromolecular complexes in neurons, glia and immune cells and regulate signals used for neuro-immune communication in the pain pathway. Therefore, miRNAs may be hypothesized as critically important master switches modulating chronic pain. In particular, understanding the concerted function of miRNA in the regulation of nociception and endogenous analgesia and defining the importance of miRNAs in the circuitries and cognitive, emotional and behavioral components involved in pain is expected to shed new light on the enigmatic pathophysiology of neuropathic pain, migraine and complex regional pain syndrome. Specific miRNAs may evolve as new druggable molecular targets for pain prevention and relief. Furthermore, predisposing miRNA expression patterns and inter-individual variations and polymorphisms in miRNAs and/or their binding sites may serve as biomarkers for pain and help to predict individual risks for certain types of pain and responsiveness to analgesic drugs. miRNA-based diagnostics are expected to develop into hands-on tools that allow better patient stratification, improved mechanism-based treatment, and targeted prevention strategies for high risk individuals.}, language = {en} } @phdthesis{Sommer2005, author = {Sommer, Florian}, title = {Vorteilhafte Effekte einer sp{\"a}ten Reperfusion auf das Remodeling des Restmyokards nach experimentellem Verschluss eines Koronargef{\"a}ßes am Model der Ratte}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-22520}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2005}, abstract = {Einleitung: Der Myokardinfarkt ist mit einer hohen Mortalit{\"a}t und Morbidit{\"a}t belastet. Beide Gegebenheiten lassen sich durch eine fr{\"u}hzeitige Reperfusion senken. Viele Hinweise zeigen einen Benefit einer sp{\"a}ten Reperfusion nach einem Myokardinfarkt, wobei die Mechanismen, die zu diesem Vorteil f{\"u}hren noch unklar sind. Methodik: Operative Myokardinfarktprovokation an weiblichen Ratten mit anschließender Reperfusion nach 2 Std. und 3 Tagen, Messung der h{\"a}modynamischen Parameter nach 12 Wochen, dann Organentnahme und histologische, morphologische und immunhistochemische Auswertung sowie Gewebeaufbereitung, SDS-Page und Proteinnachweis mit Western Blot. Ergebnisse: H{\"a}modynamisch und morphologisch zeigten sich nach 12 Wochen neben bekannten Ver{\"a}nderungen auch eine signifikante Verringerung des Lungengewichts/KG sowie der Infarktexpansion bei Reperfusion nach 2h und 3d. Des weiteren wurde durch 2h-Reperfusion das links- und rechtsventrikul{\"a}re Gewicht, sowie die LV-Cavit{\"a}t vermindert, die LV-Narbendicke nahm zu. F{\"u}r MMP-2 fand sich dagegen nach 12 Wochen nur f{\"u}r die permanente Infarktgruppe eine signifikante Zunahme, nicht f{\"u}r die beiden Reperfusionsgruppen. Zur Untersuchung von m{\"o}glichen Zusammenh{\"a}ngen zwischen h{\"a}modynamischen, bzw. morphologischen Ver{\"a}nderungen und der Expression von MMP`s und TIMP`s wurden Regressionsanalysen durchgef{\"u}hrt.

Methods Screening of a large cohort of patient sera for anti-NF autoantibodies by ELISA and further characterization by cell-based assays, epitope mapping, and complement binding assays. Results Two different clinical phenotypes became apparent in this study: The well-known clinical picture of subacute-onset severe sensorimotor neuropathy with tremor that is known to be associated with IgG4 autoantibodies against the paranodal isoform NF-155 was found in 2 patients. The second phenotype with a dramatic course of disease with tetraplegia and almost locked-in syndrome was associated with IgG3 autoantibodies against nodal and paranodal isoforms of NF in 3 patients. The epitope against which these autoantibodies were directed in this second phenotype was the common Ig domain found in all 3 NF isoforms. In contrast, anti-NF-155 IgG4 were directed against the NF-155-specific Fn3Fn4 domain. The description of a second phenotype of anti-NF-associated neuropathy is in line with some case reports of similar patients that were published in the last year. Conclusions Our results indicate that anti-pan-NF-associated neuropathy differs from anti-NF-155-associated neuropathy, and epitope and subclass play a major role in the pathogenesis and severity of anti-NF-associated neuropathy and should be determined to correctly classify patients, also in respect to possible differences in therapeutic response.}, language = {en} } @article{AppeltshauserMessingerStarzetal.2022, author = {Appeltshauser, Luise and Messinger, Julia and Starz, Katharina and Heinrich, David and Brunder, Anna-Michelle and Stengel, Helena and Fiebig, Bianca and Ayzenberg, Ilya and Birklein, Frank and Dresel, Christian and Dorst, Johannes and Dvorak, Florian and Grimm, Alexander and Joerk, Alexander and Leypoldt, Frank and M{\"a}urer, Mathias and Merl, Patrick and Michels, Sebastian and Pitarokoili, Kalliopi and Rosenfeldt, Mathias and Sperfeld, Anne-Dorte and Weihrauch, Marc and Welte, Gabriel Simon and Sommer, Claudia and Doppler, Kathrin}, title = {Diabetes Mellitus Is a Possible Risk Factor for Nodo-paranodopathy With Antiparanodal Autoantibodies}, series = {Neurology: Neuroimmunology \& Neuroinflammation}, volume = {9}, journal = {Neurology: Neuroimmunology \& Neuroinflammation}, number = {3}, doi = {10.1212/NXI.0000000000001163}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-300551}, year = {2022}, abstract = {Background and Objectives Nodo-paranodopathies are peripheral neuropathies with dysfunction of the node of Ranvier. Affected patients who are seropositive for antibodies against adhesion molecules like contactin-1 and neurofascin show distinct clinical features and a disruption of the paranodal complex. An axoglial dysjunction is also a characteristic finding of diabetic neuropathy. Here, we aim to investigate a possible association of antibody-mediated nodo-paranodopathy and diabetes mellitus (DM). Methods We retrospectively analyzed clinical data of 227 patients with chronic inflammatory demyelinating polyradiculoneuropathy and Guillain-Barr{\´e} syndrome from multiple centers in Germany who had undergone diagnostic testing for antiparanodal antibodies targeting neurofascin-155, pan-neurofascin, contactin-1-associated protein 1, and contactin-1. To study possible direct pathogenic effects of antiparanodal antibodies, we performed immunofluorescence binding assays on human pancreatic tissue sections. Results The frequency of DM was 33.3\% in seropositive patients and thus higher compared with seronegative patients (14.1\%, OR = 3.04, 95\% CI = 1.31-6.80). The relative risk of DM in seropositive patients was 3.4-fold higher compared with the general German population. Seropositive patients with DM most frequently harbored anti-contactin-1 antibodies and had higher antibody titers than seropositive patients without DM. The diagnosis of DM preceded the onset of neuropathy in seropositive patients. No immunoreactivity of antiparanodal antibodies against pancreatic tissue was detected. Discussion We report an association of nodo-paranodopathy and DM. Our results suggest that DM may be a potential risk factor for predisposing to developing nodo-paranodopathy and argue against DM being induced by the autoantibodies. Our findings set the basis for further research investigating underlying immunopathogenetic connections.}, language = {en} }
