It is part of the European Society for Immunodeficiencies (ESID) registry. The primary purpose of the registry is to gather data on the epidemiology, diagnostic delay, diagnosis, and treatment of PIDs. Methods: Clinical and laboratory data was collected from 2,453 patients from 36 German PID centres in an online registry. Data was analysed with the software Stata® and Excel. Results: The minimum prevalence of PID in Germany is 2.72 per 100,000 inhabitants. Among patients aged 1-25, there was a clear predominance of males. The median age of living patients ranged between 7 and 40 years, depending on the respective PID. Predominantly antibody disorders were the most prevalent group with 57\% of all 2,453 PID patients (including 728 CVID patients). A gene defect was identified in 36\% of patients. Familial cases were observed in 21\% of patients. The age of onset for presenting symptoms ranged from birth to late adulthood (range 0-88 years). Presenting symptoms comprised infections (74\%) and immune dysregulation (22\%). Ninety-three patients were diagnosed without prior clinical symptoms. Regarding the general and clinical diagnostic delay, no PID had undergone a slight decrease within the last decade. However, both, SCID and hyper IgE-syndrome showed a substantial improvement in shortening the time between onset of symptoms and genetic diagnosis. Regarding treatment, 49\% of all patients received immunoglobulin G (IgG) substitution (70\%-subcutaneous; 29\%-intravenous; 1\%-unknown). Three-hundred patients underwent at least one hematopoietic stem cell transplantation (HSCT). Five patients had gene therapy. Conclusion: The German PID-NET registry is a precious tool for physicians, researchers, the pharmaceutical industry, politicians, and ultimately the patients, for whom the outcomes will eventually lead to a more timely diagnosis and better treatment.}, language = {en} } @unpublished{VolkmannBockSeibtetal.2012, author = {Volkmann, Armin and Bock, Sina and Seibt, Daniela and K{\"u}mmet, Sonja and Weiß, Michael and Dietz, Elisabeth and Huss, Patrick and Heer, Anna and El Hassan, Naitelqadi}, title = {Geisteswissenschaft und Geografische Informationssysteme (GIS): Erstellung von Kartierungen mit kommerzieller und Open Source Software im Vergleich}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-74470}, year = {2012}, abstract = {Der Einsatz von Geographischen Informationssystemen (GIS) bietet auch f{\"u}r die Geisteswissenschaften zahlreiche Ans{\"a}tze zur Generierung von neuem Wissen.

Ablation procedures that use catheters with irrigated tips are well established therapeutic options for the treatment of cardiac arrhythmias and when used in a modified mode might offer an additional system for suppressing passive catheter heating. Methods: A two-step approach was chosen. Firstly, tests on passive catheter heating were performed in a 1.5 T Avanto system (Siemens Healthcare Sector, Erlangen, Germany) using a ASTM Phantom in order to determine a possible maximum temperature rise. Secondly, a phantom was designed for simulation of the interface between blood and the vascular wall. The MR-RF induced temperature rise was simulated by catheter tip heating via a standard ablation generator. Power levels from 1 to 6 W were selected. Ablation duration was 120 s with no tip irrigation during the first 60 s and irrigation at rates from 2 ml/min to 35 ml/min for the remaining 60 s (Biotronik Qiona Pump, Berlin, Germany). The temperature was measured with fluoroscopic sensors (Luxtron, Santa Barbara, CA, USA) at a distance of 0 mm, 2 mm, 4 mm, and 6 mm from the catheter tip. Results: A maximum temperature rise of 22.4 degrees C at the catheter tip was documented in the MR scanner. This temperature rise is equivalent to the heating effect of an ablator's power output of 6 W at a contact force of the weight of 90 g (0.883 N). The catheter tip irrigation was able to limit the temperature rise to less than 2 degrees C for the majority of examined power levels, and for all examined power levels the residual temperature rise was less than 8 degrees C. Conclusion: Up to a maximum of 22.4 degrees C, the temperature rise at the tissue surface can be entirely suppressed by using the catheter's own irrigation system. The irrigated tip system can be used to increase MR safety of EP catheters by suppressing the effects of unwanted passive catheter heating due to RF exposure from the MR scanner.}, language = {en} } @article{BeierleSchobelVogeletal.2021, author = {Beierle, Felix and Schobel, Johannes and Vogel, Carsten and Allgaier, Johannes and Mulansky, Lena and Haug, Fabian and Haug, Julian and Schlee, Winfried and Holfelder, Marc and Stach, Michael and Schickler, Marc and Baumeister, Harald and Cohrdes, Caroline and Deckert, J{\"u}rgen and Deserno, Lorenz and Edler, Johanna-Sophie and Eichner, Felizitas A. and Greger, Helmut and Hein, Grit and Heuschmann, Peter and John, Dennis and Kestler, Hans A. and Krefting, Dagmar and Langguth, Berthold and Meybohm, Patrick and Probst, Thomas and Reichert, Manfred and Romanos, Marcel and St{\"o}rk, Stefan and Terhorst, Yannik and Weiß, Martin and Pryss, R{\"u}diger}, title = {Corona Health — A Study- and Sensor-Based Mobile App Platform Exploring Aspects of the COVID-19 Pandemic}, series = {International Journal of Environmental Research and Public Health}, volume = {18}, journal = {International Journal of Environmental Research and Public Health}, number = {14}, issn = {1660-4601}, doi = {10.3390/ijerph18147395}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-242658}, year = {2021}, abstract = {Physical and mental well-being during the COVID-19 pandemic is typically assessed via surveys, which might make it difficult to conduct longitudinal studies and might lead to data suffering from recall bias. Ecological momentary assessment (EMA) driven smartphone apps can help alleviate such issues, allowing for in situ recordings. Implementing such an app is not trivial, necessitates strict regulatory and legal requirements, and requires short development cycles to appropriately react to abrupt changes in the pandemic. Based on an existing app framework, we developed Corona Health, an app that serves as a platform for deploying questionnaire-based studies in combination with recordings of mobile sensors. In this paper, we present the technical details of Corona Health and provide first insights into the collected data. Through collaborative efforts from experts from public health, medicine, psychology, and computer science, we released Corona Health publicly on Google Play and the Apple App Store (in July 2020) in eight languages and attracted 7290 installations so far. Currently, five studies related to physical and mental well-being are deployed and 17,241 questionnaires have been filled out. Corona Health proves to be a viable tool for conducting research related to the COVID-19 pandemic and can serve as a blueprint for future EMA-based studies.

In HSV-1 infection, but not upon salt or heat stress, this is accompanied by a dramatic increase in chromatin accessibility downstream of genes. Here, we show that the HSV-1 immediate-early protein ICP22 is both necessary and sufficient to induce downstream open chromatin regions (dOCRs) when transcription termination is disrupted by the viral ICP27 protein. This is accompanied by a marked ICP22-dependent loss of histones downstream of affected genes consistent with impaired histone repositioning in the wake of Pol II. Efficient knock-down of the ICP22-interacting histone chaperone FACT is not sufficient to induce dOCRs in ΔICP22 infection but increases dOCR induction in wild-type HSV-1 infection. Interestingly, this is accompanied by a marked increase in chromatin accessibility within gene bodies. We propose a model in which allosteric changes in Pol II composition downstream of genes and ICP22-mediated interference with FACT activity explain the differential impairment of histone repositioning downstream of genes in the wake of Pol II in HSV-1 infection.}, language = {en} } @article{SchofferSchueleinArandetal.2016, author = {Schoffer, Olaf and Sch{\"u}lein, Stefanie and Arand, Gerlinde and Arnholdt, Hans and Baaske, Dieter and Bargou, Ralf C. and Becker, Nikolaus and Beckmann, Matthias W. and Bodack, Yves and B{\"o}hme, Beatrix and Bozkurt, Tayfun and Breitsprecher, Regine and Buchali, Andre and Burger, Elke and Burger, Ulrike and Dommisch, Klaus and Elsner, Gudrun and Fernschild, Karin and Flintzer, Ulrike and Funke, Uwe and Gerken, Michael and G{\"o}bel, Hubert and Grobe, Norbert and Gumpp, Vera and Heinzerling, Lucie and Kempfer, Lana Raffaela and Kiani, Alexander and Klinkhammer-Schalke, Monika and Kl{\"o}cking, Sabine and Kreibich, Ute and Knabner, Katrin and Kuhn, Peter and Lutze, Stine and M{\"a}der, Uwe and Maisel, Tanja and Maschke, Jan and Middeke, Martin and Neubauer, Andreas and Niedostatek, Antje and Opazo-Saez, Anabelle and Peters, Christoph and Schell, Beatrice and Schenkirsch, Gerhard and Schmalenberg, Harald and Schmidt, Peter and Schneider, Constanze and Schubotz, Birgit and Seide, Anika and Strecker, Paul and Taubenheim, Sabine and Wackes, Matthias and Weiß, Steffen and Welke, Claudia and Werner, Carmen and Wittekind, Christian and Wulff, J{\"o}rg and Zettl, Heike and Klug, Stefanie J.}, title = {Tumour stage distribution and survival of malignant melanoma in Germany 2002-2011}, series = {BMC Cancer}, volume = {16}, journal = {BMC Cancer}, number = {936}, doi = {10.1186/s12885-016-2963-0}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-164544}, year = {2016}, abstract = {Background Over the past two decades, there has been a rising trend in malignant melanoma incidence worldwide. In 2008, Germany introduced a nationwide skin cancer screening program starting at age 35. The aims of this study were to analyse the distribution of malignant melanoma tumour stages over time, as well as demographic and regional differences in stage distribution and survival of melanoma patients. Methods Pooled data from 61 895 malignant melanoma patients diagnosed between 2002 and 2011 and documented in 28 German population-based and hospital-based clinical cancer registries were analysed using descriptive methods, joinpoint regression, logistic regression and relative survival. Results The number of annually documented cases increased by 53.2\% between 2002 (N = 4 779) and 2011 (N = 7 320). There was a statistically significant continuous positive trend in the proportion of stage UICC I cases diagnosed between 2002 and 2011, compared to a negative trend for stage UICC II. No trends were found for stages UICC III and IV respectively. Age (OR 0.97, 95\% CI 0.97-0.97), sex (OR 1.18, 95\% CI 1.11-1.25), date of diagnosis (OR 1.05, 95\% CI 1.04-1.06), 'diagnosis during screening' (OR 3.24, 95\% CI 2.50-4.19) and place of residence (OR 1.23, 95\% CI 1.16-1.30) had a statistically significant influence on the tumour stage at diagnosis. The overall 5-year relative survival for invasive cases was 83.4\% (95\% CI 82.8-83.9\%). Conclusions No distinct changes in the distribution of malignant melanoma tumour stages among those aged 35 and older were seen that could be directly attributed to the introduction of skin cancer screening in 2008.

The interaction of NK cells with the human pathogen Aspergillus (A.) fumigatus is mediated by the fungal recognition receptor CD56, which is relocated to the fungal interface after contact. Blocking of CD56 signaling inhibits the fungal mediated chemokine secretion of MIP-1α, MIP-1β, and RANTES and reduces cell activation, indicating a functional role of CD56 in fungal recognition. We collected peripheral blood from recipients of an allograft at defined time points after alloSCT (day 60, 90, 120, 180). NK cells were isolated, directly challenged with live A. fumigatus germ tubes, and cell function was analyzed and compared to healthy age and gender-matched individuals. After alloSCT, NK cells displayed a higher percentage of CD56\(^{bright}\)CD16\(^{dim}\) cells throughout the time of blood collection. However, CD56 binding and relocalization to the fungal contact side were decreased. We were able to correlate this deficiency to the administration of corticosteroid therapy that further negatively influenced the secretion of MIP-1α, MIP-1β, and RANTES. As a consequence, the treatment of healthy NK cells ex vivo with corticosteroids abrogated chemokine secretion measured by multiplex immunoassay. Furthermore, we analyzed NK cells regarding their actin cytoskeleton by Structured Illumination Microscopy (SIM) and flow cytometry and demonstrate an actin dysfunction of NK cells shown by reduced F-actin content after fungal co-cultivation early after alloSCT. This dysfunction remains until 180 days post-alloSCT, concluding that further actin-dependent cellular processes may be negatively influenced after alloSCT. To investigate the molecular pathomechansism, we compared CD56 receptor mobility on the plasma membrane of healthy and alloSCT primary NK cells by single-molecule tracking. The results were very robust and reproducible between tested conditions which point to a different molecular mechanism and emphasize the importance of proper CD56 mobility.}, language = {en} } @article{PostemaHoogmanAmbrosinoetal.2021, author = {Postema, Merel C. and Hoogman, Martine and Ambrosino, Sara and Asherson, Philip and Banaschewski, Tobias and Bandeira, Cibele E. and Baranov, Alexandr and Bau, Claiton H.D. and Baumeister, Sarah and Baur-Streubel, Ramona and Bellgrove, Mark A. and Biederman, Joseph and Bralten, Janita and Brandeis, Daniel and Brem, Silvia and Buitelaar, Jan K. and Busatto, Geraldo F. and Castellanos, Francisco X. and Cercignani, Mara and Chaim-Avancini, Tiffany M. and Chantiluke, Kaylita C. and Christakou, Anastasia and Coghill, David and Conzelmann, Annette and Cubillo, Ana I. and Cupertino, Renata B. and de Zeeuw, Patrick and Doyle, Alysa E. and Durston, Sarah and Earl, Eric A. and Epstein, Jeffery N. and Ethofer, Thomas and Fair, Damien A. and Fallgatter, Andreas J. and Faraone, Stephen V. and Frodl, Thomas and Gabel, Matt C. and Gogberashvili, Tinatin and Grevet, Eugenio H. and Haavik, Jan and Harrison, Neil A. and Hartman, Catharina A. and Heslenfeld, Dirk J. and Hoekstra, Pieter J. and Hohmann, Sarah and H{\o}vik, Marie F. and Jernigan, Terry L. and Kardatzki, Bernd and Karkashadze, Georgii and Kelly, Clare and Kohls, Gregor and Konrad, Kerstin and Kuntsi, Jonna and Lazaro, Luisa and Lera-Miguel, Sara and Lesch, Klaus-Peter and Louza, Mario R. and Lundervold, Astri J. and Malpas, Charles B and Mattos, Paulo and McCarthy, Hazel and Namazova-Baranova, Leyla and Nicolau, Rosa and Nigg, Joel T. and Novotny, Stephanie E. and Oberwelland Weiss, Eileen and O'Gorman Tuura, Ruth L. and Oosterlaan, Jaap and Oranje, Bob and Paloyelis, Yannis and Pauli, Paul and Picon, Felipe A. and Plessen, Kerstin J. and Ramos-Quiroga, J.

Here, we performed the largest ever analysis of brain left-right asymmetry in ADHD, using 39 datasets of the ENIGMA consortium. Methods We analyzed asymmetry of subcortical and cerebral cortical structures in up to 1,933 people with ADHD and 1,829 unaffected controls. Asymmetry Indexes (AIs) were calculated per participant for each bilaterally paired measure, and linear mixed effects modeling was applied separately in children, adolescents, adults, and the total sample, to test exhaustively for potential associations of ADHD with structural brain asymmetries. Results There was no evidence for altered caudate nucleus asymmetry in ADHD, in contrast to prior literature. In children, there was less rightward asymmetry of the total hemispheric surface area compared to controls (t = 2.1, p = .04). Lower rightward asymmetry of medial orbitofrontal cortex surface area in ADHD (t = 2.7, p = .01) was similar to a recent finding for autism spectrum disorder. There were also some differences in cortical thickness asymmetry across age groups. In adults with ADHD, globus pallidus asymmetry was altered compared to those without ADHD. However, all effects were small (Cohen's d from -0.18 to 0.18) and would not survive study-wide correction for multiple testing. Conclusion Prior studies of altered structural brain asymmetry in ADHD were likely underpowered to detect the small effects reported here. Altered structural asymmetry is unlikely to provide a useful biomarker for ADHD, but may provide neurobiological insights into the trait.}, language = {en} }
