Recent German health insurance data revealed low ICU survival rates. Patient characteristics and experience of the ECMO center may determine intensive care unit (ICU) survival. The current study aimed to identify factors affecting ICU survival of COVID-19 ECMO patients. Methods 673 COVID-19 ARDS ECMO patients treated in 26 centers between January 1st 2020 and March 22nd 2021 were included. Data on clinical characteristics, adjunct therapies, complications, and outcome were documented. Block wise logistic regression analysis was applied to identify variables associated with ICU-survival. Results Most patients were between 50 and 70 years of age. PaO\(_{2}\)/FiO\(_{2}\) ratio prior to ECMO was 72 mmHg (IQR: 58-99). ICU survival was 31.4\%. Survival was significantly lower during the 2nd wave of the COVID-19 pandemic. A subgroup of 284 (42\%) patients fulfilling modified EOLIA criteria had a higher survival (38\%) (p = 0.0014, OR 0.64 (CI 0.41-0.99)). Survival differed between low, intermediate, and high-volume centers with 20\%, 30\%, and 38\%, respectively (p = 0.0024). Treatment in high volume centers resulted in an odds ratio of 0.55 (CI 0.28-1.02) compared to low volume centers. Additional factors associated with survival were younger age, shorter time between intubation and ECMO initiation, BMI > 35 (compared to < 25), absence of renal replacement therapy or major bleeding/thromboembolic events. Conclusions Structural and patient-related factors, including age, comorbidities and ECMO case volume, determined the survival of COVID-19 ECMO. These factors combined with a more liberal ECMO indication during the 2nd wave may explain the reasonably overall low survival rate. Careful selection of patients and treatment in high volume ECMO centers was associated with higher odds of ICU survival.}, language = {en} } @article{LadwigLederbogenAlbusetal.2014, author = {Ladwig, Karl-Heinz and Lederbogen, Florian and Albus, Christian and Angermann, Christiane and Borggrefe, Martin and Fischer, Denise and Fritzsche, Kurt and Haass, Markus and Jordan, Jochen and J{\"u}nger, Jana and Kindermann, Ingrid and K{\"o}llner, Volker and Kuhn, Bernhard and Scherer, Martin and Seyfarth, Melchior and V{\"o}ller, Heinz and Waller, Christiane and Herrmann-Lingen, Christoph}, title = {Position paper on the importance of psychosocial factors in cardiology: Update 2013}, series = {GMS German Medical Science}, volume = {12}, journal = {GMS German Medical Science}, doi = {10.3205/000194}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-121196}, year = {2014}, abstract = {Background: The rapid progress of psychosomatic research in cardiology and also the increasing impact of psychosocial issues in the clinical daily routine have prompted the Clinical Commission of the German Heart Society (DGK) to agree to an update of the first state of the art paper on this issue which was originally released in 2008. Methods: The circle of experts was increased, general aspects were implemented and the state of the art was updated. Particular emphasis was dedicated to coronary heart diseases (CHD), heart rhythm diseases and heart failure because to date the evidence-based clinical knowledge is most advanced in these particular areas. Differences between men and women and over the life span were considered in the recommendations as were influences of cognitive capability and the interactive and synergistic impact of classical somatic risk factors on the affective comorbidity in heart disease patients. Results: A IA recommendation (recommendation grade I and evidence grade A) was given for the need to consider psychosocial risk factors in the estimation of coronary risks as etiological and prognostic risk factors. Furthermore, for the recommendation to routinely integrate psychosocial patient management into the care of heart surgery patients because in these patients, comorbid affective disorders (e.g. depression, anxiety and post-traumatic stress disorder) are highly prevalent and often have a malignant prognosis. A IB recommendation was given for the treatment of psychosocial risk factors aiming to prevent the onset of CHD, particularly if the psychosocial risk factor is harmful in itself (e.g. depression) or constrains the treatment of the somatic risk factors. Patients with acute and chronic CHD should be offered anti-depressive medication if these patients suffer from medium to severe states of depression and in this case medication with selective reuptake inhibitors should be given. In the long-term course of treatment with implanted cardioverter defibrillators (ICDs) a subjective health technology assessment is warranted. In particular, the likelihood of affective comorbidities and the onset of psychological crises should be carefully considered. Conclusions: The present state of the art paper presents an update of current empirical evidence in psychocardiology. The paper provides evidence-based recommendations for the integration of psychosocial factors into cardiological practice and highlights areas of high priority. The evidence for estimating the efficiency for psychotherapeutic and psychopharmacological interventions has increased substantially since the first release of the policy document but is, however, still weak. There remains an urgent need to establish curricula for physician competence in psychodiagnosis, communication and referral to ensure that current psychocardiac knowledge is translated into the daily routine.}, language = {en} } @article{GreiteStoermerGueleretal.2022, author = {Greite, Robert and St{\"o}rmer, Johanna and Gueler, Faikah and Khalikov, Rasul and Haverich, Axel and K{\"u}hn, Christian and Madrahimov, Nodir and Natanov, Ruslan}, title = {Different acute kidney injury patterns after renal ischemia reperfusion injury and extracorporeal membrane oxygenation in mice}, series = {International Journal of Molecular Sciences}, volume = {23}, journal = {International Journal of Molecular Sciences}, number = {19}, issn = {1422-0067}, doi = {10.3390/ijms231911000}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-288282}, year = {2022}, abstract = {The use of extracorporeal membrane oxygenation (ECMO) is associated with acute kidney injury (AKI) in thoracic organ transplantation. However, multiple other factors contribute to AKI development after these procedures such as renal ischemia-reperfusion injury (IRI) due to hypo-perfusion of the kidney during surgery. In this study, we aimed to explore the kidney injury patterns in mouse models of ECMO and renal IRI. Kidneys of C57BL/6 mice were examined after moderate (35 min) and severe (45 min) unilateral transient renal pedicle clamping and 2 h of veno-venous ECMO. Renal injury markers, neutrophil infiltration, tubular transport function, pro-inflammatory cytokines, and renal heme oxygenase-1 (HO-1) expression were determined by immunofluorescence and qPCR. Both procedures caused AKI, but with different injury patterns. Severe neutrophil infiltration of the kidney was evident after renal IRI, but not following ECMO. Tubular transport function was severely impaired after renal IRI, but preserved in the ECMO group. Both procedures caused upregulation of pro-inflammatory cytokines in the renal tissue, but with different time kinetics. After ECMO, but not IRI, HO-1 was strongly induced in tubular cells indicating contact with hemolysis-derived proteins. After IRI, HO-1 was expressed on infiltrating myeloid cells in the tubulo-interstitial space. In conclusion, renal IRI and ECMO both caused AKI, but kidney damage after renal IRI was more pronounced including severe neutrophil infiltration and tubular transport impairment. Enhanced HO-1 expression in tubular cells after ECMO encourages limitation of hemolysis as a therapeutic approach to reduce ECMO-associated AKI.}, language = {en} } @article{LindhoffLastBirschmannBidenharnetal.2022, author = {Lindhoff-Last, Edelgard and Birschmann, Ingvild and Bidenharn, Antonia J. and Kuhn, Joachim and Lindau, Simone and Konstantinides, Stavros and Grottke, Oliver and Nowak-G{\"o}ttl, Ulrike and Lucks, Jessica and Zydek, Barbara and Heymann, Christian von and S{\"u}mnig, Ariane and Beyer-Westendorf, Jan and Schellong, Sebastian and Meybohm, Patrick and Greinacher, Andreas and Herrmann, Eva}, title = {Pharmacokinetics of phenprocoumon in emergency situations - results of the prospective observational RADOA-registry (reversal agent use in patients treated with direct oral anticoagulants or vitamin K antagonists registry)}, series = {Pharmaceuticals}, volume = {15}, journal = {Pharmaceuticals}, number = {11}, issn = {1424-8247}, doi = {10.3390/ph15111437}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-297226}, year = {2022}, abstract = {Background: Phenprocoumon has been used as an oral anticoagulant in patients with thromboembolic disease for more than 40 years. So far its pharmacokinetics have not been analyzed in emergency situations. Methods: Phenprocoumon-treated patients with major bleeding or urgent surgery were included in a prospective, observational registry. Phenprocoumon drug concentrations were analyzed in samples, collected as part of routine care using ultraperformance liquid chromatography tandem mass spectrometry. Moreover, anticoagulant intensity and drug half-life (t1/2) were calculated. Results: 115 patients were included. Phenprocoumon levels declined over time with a half-life of 5.27 and 5.29 days in patients with major bleedings (n = 82) and with urgent surgery (n = 33). Baseline phenprocoumon levels were 2.2 times higher in the bleeding group compared to the surgery group (1.92 vs. 0.87 ng/mL, p < 0.0001). International normalized ratio (INR) values decreased rapidly during the first 24 h. In 27.6\% of patients a rebound of INR (recurrent increase > 1.5) was observed which was associated with significantly increased bleeding rates (22\% vs. 4.2\% in patients with or without INR rebound, p = 0.012). Conclusions: In emergency situations, the long half-life of phenprocoumon may cause INR rebound and associated recurrent bleedings. Optimal management may need to include repeated vitamin K supplementation over days.}, language = {en} } @article{TischerStuppJansonetal.2021, author = {Tischer, Christina and Stupp, Carolin and Janson, Patrick and Willeke, Kristina and Hung, Chu-Wei and Fl{\"o}ter, Jessica and Kirchner, Anna and Zink, Katharina and Eder, Lisa and Hackl, Christina and M{\"u}hle, Ursula and Weidmann, Manfred and Nennstiel, Uta and Kuhn, Joseph and Weidner, Christian and Liebl, Bernhard and Wildner, Manfred and Keil, Thomas}, title = {Evaluation of screening tests in Bavarian healthcare facilities during the second wave of the SARS-CoV-2 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/ijerph18147371}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-242637}, year = {2021}, abstract = {Due to the lack of data on asymptomatic SARS-CoV-2-positive persons in healthcare institutions, they represent an inestimable risk. Therefore, the aim of the current study was to evaluate the first 1,000,000 reported screening tests of asymptomatic staff, patients, residents, and visitors in hospitals and long-term care (LTC) facilities in the State of Bavaria over a period of seven months. Data were used from the online database BayCoRei (Bavarian Corona Screening Tests), established in July 2020. Descriptive analyses were performed, describing the temporal pattern of persons that tested positive for SARS-CoV-2 by real-time polymerase chain reaction (RT-PCR) or antigen tests, stratified by facility. Until 15 March 2021, this database had collected 1,038,146 test results of asymptomatic subjects in healthcare facilities (382,240 by RT-PCR, and 655,906 by antigen tests). Of the RT-PCR tests, 2.2\% (n = 8380) were positive: 3.0\% in LTC facilities, 2.2\% in hospitals, and 1.2\% in rehabilitation institutions.

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.
