T1 - A functional genetic variation of SLC6A2 repressor hsa-miR-579-3p upregulates sympathetic noradrenergic processes of fear and anxiety JF - Translational Psychiatry N2 - Increased sympathetic noradrenergic signaling is crucially involved in fear and anxiety as defensive states. MicroRNAs regulate dynamic gene expression during synaptic plasticity and genetic variation of microRNAs modulating noradrenaline transporter gene (SLC6A2) expression may thus lead to altered central and peripheral processing of fear and anxiety. In silico prediction of microRNA regulation of SLC6A2 was confirmed by luciferase reporter assays and identified hsa-miR-579-3p as a regulating microRNA. The minor (T)-allele of rs2910931 (MAFcases = 0.431, MAFcontrols = 0.368) upstream of MIR579 was associated with panic disorder in patients (pallelic = 0.004, ncases = 506, ncontrols = 506) and with higher trait anxiety in healthy individuals (pASI = 0.029, pACQ = 0.047, n = 3112). Compared to the major (A)-allele, increased promoter activity was observed in luciferase reporter assays in vitro suggesting more effective MIR579 expression and SLC6A2 repression in vivo (p = 0.041). Healthy individuals carrying at least one (T)-allele showed a brain activation pattern suggesting increased defensive responding and sympathetic noradrenergic activation in midbrain and limbic areas during the extinction of conditioned fear. Panic disorder patients carrying two (T)-alleles showed elevated heart rates in an anxiety-provoking behavioral avoidance test (F(2, 270) = 5.47, p = 0.005). Fine-tuning of noradrenaline homeostasis by a MIR579 genetic variation modulated central and peripheral sympathetic noradrenergic activation during fear processing and anxiety. This study opens new perspectives on the role of microRNAs in the etiopathogenesis of anxiety disorders, particularly their cardiovascular symptoms and comorbidities.

Wir untersuchten, ob die Operation und der damit einhergehende Gewichtsverlust drei Monate nach dem bariatrischen Eingriff zu einer Veränderung der Aktivität des autonomen Nervensystems im thorakalen und im motorischen/peripheren Kompartiment führt. Als Parameter dienen für das thorakale Kompartiment die Herzfrequenzvariabilität und für das periphere/motorische Kompartiment vaskuläre (lnRHI und AI) und sudomotorische (Schweißvolumen, Antwortlatenz) Parameter. Unsere Ergebnisse im thorakalen Kompartiment zeigen einen Anstieg der Herzfrequenzvariabilität 3 Monate nach bariatrischer Operation. Wir schließen uns daher der Hypothese an, die mit morbider Adipositas assoziierte Erhöhung der sympathischen Aktivität im thorakalen Kompartiment könne durch bariatrische Operationen reversibel sein. Im peripheren/motorischen Kompartiment können wir keine eindeutige Veränderung der Aktivität des autonomen Nervensystems vor versus nach bariatrischer Operation beobachten. Andere Studien konnten hierzu deutlichere Ergebnisse erheben, die ebenfalls eine erhöhte sympathische Aktivität im motorischen Kompartiment zeigten, welche nach bariatrischer Operation reversibel war. Insgesamt können wir die These einer autonomen Imbalance bei Adipositas sowie einer Verringerung der sympathischen Aktivität im thorakalen Kompartiment nach bariatrischer Operation unterstützen. Die Veränderungen im autonomen Nervensystem leisten möglicherweise einen Beitrag zur Verbesserung der kardiovaskulären Gesundheit und der metabolischen Situation nach der bariatrischen Operation. N2 - The present work addresses the activity of the autonomic nervous system comparing before versus after bariatric surgery in subjects with morbid obesity. We investigated whether surgery and associated weight loss led to changes in autonomic nervous system activity in the thoracic and motoric/peripheral compartment three months after bariatric surgery. Heart rate variability serves as parameter for the thoracic compartment, vascular (lnRHI and AI) and sudomotor (sweat volume, response latency) parameters for the peripheral/motoric compartment. Our results in the thoracic compartment show an increase in heart rate variability 3 months after bariatric surgery. We therefore agree with the hypothesis that the increase in sympathetic activity in the thoracic compartment associated with morbid obesity could be reversible by bariatric surgery. In the peripheral/motoric compartment, we did not observe any clear change in autonomic nervous system activity comparing before versus after bariatric surgery. Other studies were able to obtain clearer results showing increased sympathetic activity in the motoric compartment in subjects with morbid obesity that was reversible after bariatric surgery. Overall, we can support the hypothesis of an autonomic imbalance in obesity and a reduction in sympathetic activity in the thoracic compartment after bariatric surgery. The changes in the autonomic nervous system may contribute to improving cardiovascular health and metabolic status after bariatric surgery.

A1 - Eisenhofer, Graeme A1 - Bechmann, Nicole T1 - Metastatic pheochromocytoma and paraganglioma: signs and symptoms related to catecholamine secretion JF - Discover Oncology N2 - Background The presence or future development of metastatic pheochromocytomas or paragangliomas (mPPGLs) can be difficult to diagnose or predict at initial presentation. Since production of catecholamines from mPPGLs is different from non-metastatic tumors (non-mPPGLs), this study aimed to clarify whether presenting catecholamine-related signs and symptoms (cSS) might also differ. Methods The study included 249 patients, 43 with mPPGL and 206 with non-mPPGL. Clinical data at the time of biochemical diagnosis (i.e. at entry into the study) were used to generate a cumulative score of cSS for each patient. Results Patients with mPPGL were significantly younger (43.3 ± 14 vs. 48.9 ± 16.1 years) and included a lower proportion of females (39.5% vs. 60.7%) than patients with non-mPPGLs. Frequencies of signs and symptoms did not differ between the two groups. Patients with mPPGLs had lower (P < 0.001) urinary excretion of epinephrine (3.5 (IQR, 1.9—6.5) µg/day) than those with non-mPPGLs (19.1 (IQR, 4.3—70.2) µg/day). There was no difference in urinary excretion of norepinephrine. In patients with mPPGLs a high cSS score was associated with high urinary excretion of norepinephrine and normetanephrine. In contrast, in patients with non-mPPGLs, a high cSS was associated with high urinary excretion of epinephrine and metanephrine. Conclusion Although presenting signs and symptoms were associated with production of norepinephrine in patients with mPPGLs and of epinephrine in patients with non-mPPGLs, there were no differences in signs and symptoms between the two groups. Therefore, consideration of signs and symptoms does not appear helpful for distinguishing patients with and without mPPGLs.

A1 - Schreiner, J. A1 - Saeger, W. T1 - Adrenal cancer: relevance of different grading systems and subtypes JF - Clinical and Translational Oncology N2 - Purpose The subclassification of adrenal cancers according to the WHO classification in ordinary, myxoid, oncocytic, and sarcomatoid as well as pediatric types is well established, but the criteria for each subtype are not sufficiently determined and the relative frequency of the different types of adrenal cancers has not been studied in large cohorts. Therefore, our large collection of surgically removed adrenal cancers should be reviewed o establish the criteria for the subtypes and to find out the frequency of the various types. Methods In our series of 521 adrenal cancers the scoring systems of Weiss et al., Hough et al., van Slooten et al. and the new Helsinki score system were used for the ordinary type of cancer (97% of our series) and the myxoid type (0.8%). For oncocytic carcinomas (2%), the scoring system of Bisceglia et al. was applied. Results Discrepancies between benign and malignant diagnoses from the first thee classical scoring systems are not rare (22% in our series) and could be resolved by the Helsinki score especially by Ki-67 index (more than 8% unequivocally malignant). Since all our cancer cases are positive in the Helsinki score, this system can replace the three elder systems. For identification of sarcomatoid cancer as rarest type in our series (0.2%), the scoring systems are not practical but additional immunostainings used for soft tissue tumors and in special cases molecular pathology are necessary to differentiate these cancers from adrenal sarcomas. According to the relative frequencies of the different subtypes of adrenal cancers the main type is the far most frequent (97%) followed by the oncocytic type (2%), the myxoid type (0.8%) and the very rare sarcomatoid type (0.2%). Conclusions The Helsinki score is the best for differentiating adrenal carcinomas of the main, the oncocytic, and the myxoid type in routine work. Additional scoring systems for these carcinomas are generally not any longer necessary. Signs of proliferation (mitoses and Ki-67 index) and necroses are the most important criteria for diagnosis of malignancy.

Besides its deleterious impact on cardiovascular target organ damage, PA is considered to cause osteoporosis. Patients and methods We assessed bone turnover in a subset of 36 postmenopausal women with PA. 18 patients had unilateral PA and were treated by adrenalectomy, whereas 18 patients had bilateral PA and received mineralocorticoid receptor antagonist (MRA) therapy respectively. 18 age- and BMI-matched females served as controls. To estimate bone remodeling, we measured the bone turnover markers intact procollagen 1 N-terminal propeptide, bone alkaline phosphatase, osteocalcin and tartrate resistant acid phosphatase 5b in plasma by chemiluminescent immunoassays at time of diagnosis and one year after initiation of treatment. Study design Observational longitudinal cohort study. Setting Tertiary care hospital. Results Compared with controls, patients with PA had mildly elevated osteocalcin at baseline (p = 0.013), while the other bone markers were comparable between both groups. There were no differences between the unilateral and the bilateral PA subgroup. One year after initiation of MRA treatment with spironolactone bone resorption and bone formation markers had significantly decreased in patients with bilateral PA. In contrast, patients adrenalectomized because of unilateral PA showed no significant change of bone turnover markers. Conclusion This study shows that aldosterone excess in postmenopausal women with PA is not associated with a relevant increase of bone turnover markers at baseline. However, we observed a significant decrease of bone markers in patients treated with spironolactone, but not in patients treated by adrenalectomy.

T1 - Pre- versus post-operative untargeted plasma nuclear magnetic resonance spectroscopy metabolomics of pheochromocytoma and paraganglioma JF - Endocrine N2 - Purpose Pheochromocytomas and Paragangliomas (PPGL) result in chronic catecholamine excess and serious health complications. A recent study obtained a metabolic signature in plasma from PPGL patients; however, its targeted nature may have generated an incomplete picture and a broader approach could provide additional insights. We aimed to characterize the plasma metabolome of PPGL patients before and after surgery, using an untargeted approach, and to broaden the scope of the investigated metabolic impact of these tumors. Design A cohort of 36 PPGL patients was investigated. Blood plasma samples were collected before and after surgical tumor removal, in association with clinical and tumor characteristics. Methods Plasma samples were analyzed using untargeted nuclear magnetic resonance (NMR) spectroscopy metabolomics. The data were evaluated using a combination of uni- and multi-variate statistical methods. Results Before surgery, patients with a nonadrenergic tumor could be distinguished from those with an adrenergic tumor based on their metabolic profiles. Tyrosine levels were significantly higher in patients with high compared to those with low BMI. Comparing subgroups of pre-operative samples with their post-operative counterparts, we found a metabolic signature that included ketone bodies, glucose, organic acids, methanol, dimethyl sulfone and amino acids. Three signals with unclear identities were found to be affected. Conclusions Our study suggests that the pathways of glucose and ketone body homeostasis are affected in PPGL patients. BMI-related metabolite levels were also found to be altered, potentially linking muscle atrophy to PPGL. At baseline, patient metabolomes could be discriminated based on their catecholamine phenotype.

The number of individuals with primary and secondary adrenal insufficiency in Europe is estimated to be 20–50/100.000. A growing number of AI cases are due to side effects of GC treatment used in different treatment strategies for cancer and to immunotherapy in cancer treatment. The benefit of hormone replacement therapy is evident but long-term adverse effects may arise due to the non-physiological GC doses and treatment regimens used. Given multiple GC replacement formulations available comprising short-acting, intermediate, long-acting and novel modified-release hydrocortisone as well as subcutaneous formulations, this review offers a concise summary on the latest therapeutic improvements for treatment of AI and prevention of adrenal crises. As availability of various glucocorticoid formulations and access to expert centers across Europe varies widely, European Reference Networks on rare endocrine conditions aim at harmonizing treatment and ensure access to specialized patient care for individual case-by-case treatment decisions. To improve the availability across Europe to cost effective oral and parenteral formulations of hydrocortisone will save lives.

We compared clinical characteristics of immunotherapy-induced hypophysitis (IIH) and primary hypophysitis (PH) Design Retrospective multicenter cohort study including 56 patients with IIH and 60 patients with PH. Methods All patients underwent extensive endocrine testing. Data on age, gender, symptoms, endocrine dysfunction, MRI, immunotherapeutic agents and autoimmune diseases were collected. Results Median time of follow-up was 18 months in IIH and 69 months in PH. The median time from initiation of immunotherapy to IIH diagnosis was 3 months. IIH affected males more frequently than PH (p < 0.001) and led to more impaired pituitary axes in males (p < 0.001). The distribution of deficient adenohypophysial axes was comparable between both entities, however, central hypocortisolism was more frequent (p < 0.001) and diabetes insipidus considerably less frequent in IIH (p < 0.001). Symptoms were similar except that visual impairment occurred more rarely in IIH (p < 0.001). 20 % of IIH patients reported no symptoms at all. Regarding MRI, pituitary stalk thickening was less frequent in IIH (p = 0.009). Concomitant autoimmune diseases were more prevalent in PH patients before the diagnosis of hypophysitis (p = 0.003) and more frequent in IIH during follow-up (p = 0.002). Conclusions Clinically, IIH and PH present with similar symptoms. Diabetes insipidus very rarely occurs in IIH. Central hypocortisolism, in contrast, is a typical feature of IIH. Preexisting autoimmunity seems not to be indicative of developing IIH.

In mock-up scenarios, we systematically assessed whether a motion detector (MD) attached to the bed may help in identifying emergencies. Methods: We recruited 15 employees of the ICU and equipped an ICU bed with an MD (IRON Software GmbH, Grünwald, Germany). Participants were asked to replay 22 mock-up scenes of one-minute duration each: 12 scenes with movements and 10 without movements, of which 5 were emergency scenes (“lying dead-still, with no or very shallow breathing”). Blinded recordings were presented to an evaluation panel consisting of an experienced ICU nurse and a physician, who was asked to assess and rate the presence of motions. Results: Fifteen participants (nine women; 173 ± 7.0 cm; 78 ± 19 kg) joined the study. In total, 286 out of 330 scenes (86.7%) were rated correctly. Ratings were false negative (FN: “no movements detected, but recorded”) in 7 out of 180 motion scenes (3.9%). Ratings were false positive (FP: “movements detected, but not recorded”) in 37 out of 150 scenes (24.7%), more often in men than women (26 out of 60 vs. 11 out of 90, respectively; p < 0.001). Of note, in 16 of these 37 FP-rated scenes, a vibrating mobile phone was identified as a potential confounder. The emergency scenes were correctly rated in 64 of the 75 runs (85.3%); 10 of the 11 FP-rated scenes occurred in male subjects. Conclusions: The MD allowed for identifying motions of test subjects with high sensitivity (96%) and acceptable specificity (75%). Accuracy might increase further if activities are recorded continuously under real-world conditions.

As further treatment options are needed and ACC metastases are sensitive to external beam radiation, novel theranostic approaches could complement established therapeutic concepts. Recent developments focus on targeting adrenal cortex-specific enzymes like the theranostic twin [\(^{123/131}\)I]IMAZA that shows a good image quality and a promising therapeutic effect in selected patients. But other established molecular targets in nuclear medicine such as the C-X-C motif chemokine receptor 4 (CXCR4) could possibly enhance the therapeutic regimen as well in a subgroup of patients. The aims of this review are to give an overview of innovative radiopharmaceuticals for the treatment of ACC and to present the different molecular targets, as well as to show future perspectives for further developments since a radiopharmaceutical with a broad application range is still warranted.

Guidelines recommend endocrine work-up in addition to radiological imaging for follow-up in ACC, but data on this topic are scarce. Patients were included in this retrospective study if pre-therapeutic hormone values, regular tumour evaluation by imaging, steroid measurements by LC–MS/MS, and details on therapies were available. The utility of steroid profiles in detecting recurrence or disease progression was assessed, whereby “endocrine progress” was defined by an elevation of at least 3 of 13 analysed hormones. Cohort A included 47 patients after R0 resection, of whom 15 experienced recurrence and 32 did not. In cohort B, 52 patients with advanced disease (including 7 patients of cohort A with recurrence) could be evaluated on 74 visits when progressive disease was documented. In 20 of 89 cases with documented disease progression, “endocrine progress” was detectable prior to radiological progress. In these cases, recurrence/progression was detected at a median of 32 days earlier by steroid measurement than by imaging, with 11-deoxycortisol and testosterone being the most sensitive markers. Notably, these patients had significantly larger tumour burden. In conclusion, steroid profiling by LC–MS/MS is of value in detecting recurrent/progressive disease in ACC.

Amyloidosis constitutes an important subgroup for which evidence is lacking. Amyloidotic fibrils originating from misfolded transthyretin and light chains are the causal agents in ATTR and AL amyloidosis. In these most frequent subtypes, cardiac involvement is the most common organ manifestation. Because cardiac and renal function frequently deteriorate over time, even under best available treatment, SGLT2i emerge as a promising treatment option due to their reno- and cardioprotective properties. We retrospectively analyzed patients with cardiac amyloidosis, who received either dapagliflozin or empagliflozin. Out of 79 patients, 5.1% had urinary tract infections; 2 stopped SGLT2i therapy; and 2.5% died unrelated to the intake of SGLT2i. No genital mycotic infections were observed. As expected, a slight drop in the glomerular filtration rate was noted, while the NYHA functional status, cardiac and hepatic function, as well as the 6 min walk distance remained stable over time. These data provide a rationale for the use of SGLT2i in patients with amyloidosis and concomitant cardiac or renal dysfunction. Prospective randomized data are desired to confirm safety and to prove efficacy in this increasingly important group of patients.

Patients mostly report severe physical impairment. Possible consequences for mental health have been scarcely studied. The aim of this study was to investigate psychological well-being in the context of GCA and PMR. Methods Cross-sectional study with N = 100 patients with GCA and/or PMR (GCA-PMR). Patient-reported outcomes (PROs) were measured using the Short Form 36 Version 2 (SF-36v2) and visual analog scale (VAS) assessment. Moreover, the Patient Health Questionnaire 9 (PHQ-9) was used in 35 of 100 patients to detect depression. To compare PROs with physician assessment, VAS was also rated from physician perspective. To assess a possible association with inflammation itself, serological parameters of inflammation (C-reactive protein [CRP], erythrocyte sedimentation rate [ESR]) were included. Results In all scales of the SF-36v2 except General Health (GH) and in the physical and mental sum score (PCS, MCS), a significant impairment compared to the German reference collective was evident (MCS: d = 0.533, p < 0.001). In the PHQ-9 categorization, 14 of the 35 (40%) showed evidence of major depression disorder. VAS Patient correlated significantly with PHQ-9 and SF-36 in all categories, while VAS Physician showed only correlations to physical categories and not in the mental dimensions. Regarding inflammatory parameters, linear regression showed CRP to be a complementary significant positive predictor of mental health subscale score, independent of pain. Conclusion PRO show a relevant impairment of mental health up to symptoms of major depression disorder. The degree of depressive symptoms is also distinctly associated with the serological inflammatory marker CRP.

T1 - Long-term health sequelae and quality of life at least 6 months after infection with SARS-CoV-2: design and rationale of the COVIDOM-study as part of the NAPKON population-based cohort platform (POP) JF - Infection N2 - Purpose Over the course of COVID-19 pandemic, evidence has accumulated that SARS-CoV-2 infections may affect multiple organs and have serious clinical sequelae, but on-site clinical examinations with non-hospitalized samples are rare. We, therefore, aimed to systematically assess the long-term health status of samples of hospitalized and non-hospitalized SARS-CoV-2 infected individuals from three regions in Germany. Methods The present paper describes the COVIDOM-study within the population-based cohort platform (POP) which has been established under the auspices of the NAPKON infrastructure (German National Pandemic Cohort Network) of the national Network University Medicine (NUM). Comprehensive health assessments among SARS-CoV-2 infected individuals are conducted at least 6 months after the acute infection at the study sites Kiel, Würzburg and Berlin. Potential participants were identified and contacted via the local public health authorities, irrespective of the severity of the initial infection. A harmonized examination protocol has been implemented, consisting of detailed assessments of medical history, physical examinations, and the collection of multiple biosamples (e.g., serum, plasma, saliva, urine) for future analyses. In addition, patient-reported perception of the impact of local pandemic-related measures and infection on quality-of-life are obtained. Results As of July 2021, in total 6813 individuals infected in 2020 have been invited into the COVIDOM-study. Of these, about 36% wished to participate and 1295 have already been examined at least once. Conclusion NAPKON-POP COVIDOM-study complements other Long COVID studies assessing the long-term consequences of an infection with SARS-CoV-2 by providing detailed health data of population-based samples, including individuals with various degrees of disease severity. Trial registration Registered at the German registry for clinical studies (DRKS00023742).

Ebenfalls untersuchten wir, ob es bestimmte echokardiographische Prädiktoren für eine TS- und eine PSAS gibt und ob die LVEF bei Patienten mit einer LGAS eine entscheidende Rolle spielt. Methoden: Es wurde bei 130 Patienten mit einer asymptomatischen AS im Uniklinikum Würzburg zwischen Januar 2011 und Dezember 2016 sowohl eine TTE als auch eine DSE durchgeführt. Mittels TTE wurden verschiedene echokardiographische Daten erhoben und falls die Patienten eine AVAi  0,6 cm2/m2 und eine PGmean < 40 mmHg aufwiesen, wurden sie in die Studie eingeschlossen. Sie wurden in zwei Gruppen aufgeteilt, je nachdem ob sie eine LGAS mit einer LVEF  50% oder < 50% aufwiesen. Bei allen Patienten wurde in der DSE die AVAproj berechnet und sie wurden daraufhin in zwei Untergruppen aufgeteilt, Patienten mit einer AVAproj  1 cm2 wurden der Gruppe mit einer hochgradigen LGAS (TS-LGAS) und Patienten mit einer AVAproj > 1cm2 der Gruppe mit einer pseudo-hochgradigen LGAS (PS-LGAS) zugeteilt. Alle Patientendaten wurden manuell ausgewertet. Das klinische Follow Up fand frühestens ein Jahr nach der DSE statt und bestand aus einem Telefoninterview oder einer klinischen Untersuchung. Ergebnisse: Die DSE ist zur Diagnose einer TS-LGAS bei Patienten mit einer erhaltenen LVEF von großem Nutzen. Die in der TTE gemessene AVA ist ein unabhängiger Prädiktor für eine TS-LGAS bei Patienten mit erhaltener und reduzierter LVEF. Eine verringerte MAPSE und eine reduzierte TDI-s´ sprechen bei Patienten mit erhaltener LVEF für eine TS-LGAS. Bei Patienten mit reduzierter LVEF weisen ein erhöhter sPAP und eine verringerte AV Geschwindigkeits Ratio auf eine TS-LGAS hin. Bei Zweifeln können weitere bildgebende Verfahren zur Diagnosefindung hinzugezogen werden. N2 - The aim of this study was to determine whether DSE can help differentiate between TS- and PSAS. We also investigated whether there are specific echocardiographic predictors for TS- and PSAS, and whether LVEF plays a crucial role in patients with LGAS. Methods: Both TTE and DSE were performed on 130 patients with asymptomatic AS at the University Hospital Würzburg between January 2011 and December 2016. Various echocardiographic data were collected via TTE, and if the patients had an AVAi ≤ 0.6 cm²/m² and a PGmean < 40 mmHg, they were included in the study. They were divided into two groups depending on whether they had LGAS with an LVEF ≥ 50% or < 50%. In all patients, the AVAproj was calculated during the DSE, and they were then divided into two subgroups: patients with an AVAproj ≤ 1 cm² were assigned to the true-severe LGAS group (TS-LGAS), and patients with an AVAproj > 1 cm² were assigned to the pseudo-severe LGAS group (PS-LGAS). All patient data were manually evaluated. The clinical follow-up took place at least one year after the DSE and consisted of a telephone interview or a clinical examination. Results: DSE is very useful for diagnosing TS-LGAS in patients with preserved LVEF. The AVA measured in TTE is an independent predictor for TS-LGAS in patients with preserved and reduced LVEF. A decreased MAPSE and a reduced TDI-s' indicate TS-LGAS in patients with preserved LVEF. In patients with reduced LVEF, an increased sPAP and a decreased AV velocity ratio indicate TS-LGAS. Additional imaging techniques may be used for diagnosis in cases of doubt.

Die Gruppierung erfolgte anhand der jeweiligen Baseline LVEF. Eine weitere Unterteilung erfolgte in eine ischämische oder nicht-ischämische Genese der HF. Die Subgruppen wurden anhand der Baseline klinischen Charakteristika sowie der echokardiographischen Parameter verglichen. Hier ließ sich ein relativ ähnliches Patientenklientel mit vergleichbarem Alter, Geschlecht, BMI sowie kardialen Risikofaktoren zeigen. Signifikante Unterschiede ergab der Vergleich des NYHA-Stadiums, der Nierenfunktion sowie des Auftretens von Myokardinfarkten. Die Veränderung der LVEF über die Zeit hat einen zentralen Stellenwert zur Evaluation des Outcomes von Patienten mit HFmrEF und HFrEF. Eine Verbesserung der LVEF fand sich signifikant häufiger bei HFrEF Patienten als bei HFmrEF Patienten, welche über die Zeit signifikant häufiger eine stabile LVEF aufwiesen. Außerdem war nach Auswertung der Überlebenskurven nach Kaplan-Meier in HFmrEF Patienten eine verbesserte oder unveränderte LVEF über die Zeit mit einem besseren Überleben verbunden, vor allem bei Patienten mit ischämischer Ätiologie. In der HFrEF Gruppe konnte gezeigt werden, dass sowohl Patienten mit ischämischer als auch mit nicht-ischämischer Ätiologie bei Vorliegen einer verbesserten oder unveränderten LVEF über die Zeit ein besseres Outcome aufwiesen. Eine erniedrigte MAPSE bedeutete vor allem bei HFmrEF Patienten mit nicht-ischämischer Ätiologie ein schlechteres Outcome. Die Ergebnisse dienten unter anderem der weiteren Charakterisierung der HFmrEF und HFrEF Gruppe sowie der Identifikation von Faktoren zur Beurteilung der Veränderung der LVEF über die Zeit und der Prognose des Langzeitüberlebens beider Gruppen. Ziel für die Zukunft sollte sein, auch für HFmrEF Patienten evidenzbasierte Herzinsuffizienz Therapien zu etablieren. N2 - This retrospective study at the University Hospital of Wuerzburg was designed to assess longitudinal function in relation to all-cause mortality in patients with HFmrEF and HFrEF. The grouping was based on the respective baseline LVEF. A further subdivision was made using coronary angiographic data into ischemic or non-ischemic genesis of HF. The subgroups were compared on the basis of baseline clinical characteristics and echocardiographic parameters. This revealed a relatively similar patient cohort with comparable age, gender, BMI and cardiac risk factors. Significant differences were found in the comparison of NYHA stage, renal function and the occurrence of myocardial infarction. The change in LVEF over time is of central importance for evaluating the outcome of patients with HFmrEF and HFrEF. An improvement in LVEF was significantly more common in HFrEF patients than in HFmrEF patients, who were significantly more likely to have a stable LVEF over time. Furthermore, according to the Kaplan-Meier survival curves in HFmrEF patients, improved or unchanged LVEF over time was associated with better survival, especially in patients with ischemic etiology. In the HFrEF group, it was shown that both patients with ischemic and non-ischemic etiology had a better outcome with improved or unchanged LVEF over time. A lower MAPSE was associated with a worse outcome, especially in HFmrEF patients with non-ischemic etiology. The results were used, among other things, to further characterize the HFmrEF and HFrEF groups and to identify factors for evaluating the change in LVEF over time and the prognosis of long-term survival in both groups. The aim for the future should be to establish evidence-based heart failure therapies for HFmrEF patients as well.

Lenvatinib (LEN), a multi-tyrosine kinase inhibitor targeting fibroblast growth factor receptors (FGFR) 1-4 is approved for advanced radioiodine refractory thyroid carcinoma, but response to single agent is poor in ATC. Recent reports of combining LEN with PD-1 inhibitor pembrolizumab (PEM) are promising. Materials and methods: Primary ATC (n=93) and PDTC (n=47) tissue samples diagnosed 1997-2019 at five German tertiary care centers were assessed for PD-L1 expression by immunohistochemistry using Tumor Proportion Score (TPS). FGFR 1-4 mRNA was quantified in 31 ATC and 14 PDTC with RNAscope in-situ hybridization. Normal thyroid tissue (NT) and papillary thyroid carcinoma (PTC) served as controls. Disease specific survival (DSS) was the primary outcome variable. Results: PD-L1 TPS≥50% was observed in 42% of ATC and 26% of PDTC specimens. Mean PD-L1 expression was significantly higher in ATC (TPS 30%) than in PDTC (5%; p<0.01) and NT (0%, p<0.001). 53% of PDTC samples had PD-L1 expression ≤5%. FGFR mRNA expression was generally low in all samples but combined FGFR1-4 expression was significantly higher in PDTC and ATC compared to NT (each p<0.001). No impact of PD-L1 and FGFR 1-4 expression was observed on DSS. Conclusion: High tumoral expression of PD-L1 in a large proportion of ATCs and a subgroup of PDTCs provides a rationale for immune checkpoint inhibition. FGFR expression is low thyroid tumor cells. The clinically observed synergism of PEM with LEN may be caused by immune modulation. N2 - Hintergrund: Die therapeutischen Optionen für das gering differenzierte (PDTC) und anaplastische (ATC) Schilddrüsenkarzinom sind limitiert, weshalb diese Erkrankungen überwiegend mit einer schlechten Prognose einhergehen. Lenvatinib (LEN) ist ein Multityrosinkinase-Inhibitor, der unter anderem die Fibroblasten-Wachstumsfaktor-Rezeptoren (FGFR) 1-4 inhibiert und zur Therapie des fortgeschrittenen radiojodrefraktären Schilddrüsenkarzinoms zugelassen ist. Es zeigt sich nur ein geringes Ansprechen auf die Monotherapie bei ATCs, wobei neuere Studien eine therapeutische Überlegenheit der Kombination aus LEN und dem PD-1-Inhibitor Pembrolizumab (PEM) beschreiben. Material und Methoden: Die Expression von PD-L1 wurde in ATC (n=93)- und PDTC (n=47)-Primärtumorgewebe von 1997-2019 aus fünf deutschen (Universitäts-)Kliniken mittels Immunhistochemie analysiert und mit dem Tumor Proportion Score (TPS) quantifiziert. Der Nachweis von FGFR1-4-mRNA wurde bei 31 ATC- und 14 PDTC-Gewebeproben mittels RNAscope In-situ-Hybridisierung quantifiziert. Als Kontrollgruppe wurde normales Schilddrüsengewebe (NT) und Gewebe von papillären Schilddrüsenkarzinomen (PTC) verwendet. Der primäre Endpunkt war das krankheitsspezifische Überleben (DSS). Ergebnisse: Eine PD-L1-Expression mit einem TPS ≥50% konnte in 42% der ATC- und in 26% der PDTC-Proben nachgewiesen werden. Die mediane PD-L1-Expression war in ATC-(TPS 30%) signifikant höher im Vergleich zu PDTC-Proben (5%; p<0,01) und NT (0%; p<0,001). 53% der PDTC-Proben zeigten eine PD-L1-Expression ≤5%. Die Expression von FGFR-mRNA war in allen Proben sehr gering, wobei die kombinierte FGFR1-4-Expression in PDTC- und ATC-Gewebe im Vergleich zu normalem Schilddrüsengewebe signifikant höher war (jeweils p<0,001). Es ergab sich keine Assoziation zwischen der PD-L1- und FGFR1-4-Expression mit dem krankheitsspezifischen Überleben. Schlussfolgerung: Eine hohe PD-L1-Expression in einem großen Anteil der ATCs und einem Viertel der PDTCs, könnte auf eine Rationale zur Therapieentscheidung für Immuncheckpoint-Inhibioren hinweisen. Die FGFR-Expression war in allen Schilddrüsenkarzinomen sehr gering. Der klinisch beobachtete Synergismus von PEM und LEN könnte durch immunmodulatorische Effekte hervorgerufen werden.

Specific data on the clinical and biochemical course of affected patients are lacking. Methods Retrospective study from a tertiary referral centre in Germany. After exclusion of overt hormone excess, malignancy and glucocorticoid medication, patients with adrenal incidentalomas were stratified according to serum cortisol after 1 mg dexamethasone: autonomous cortisol secretion (ACS), >5.0; possible ACS (PACS), 1.9-5.0; non-functioning adenomas (NFA), ≤1.8 µg/dl. Results A total of 260 patients were enrolled (147 women (56.5%), median follow-up 8.8 (2.0-20.8) years). At initial diagnosis, median age was 59.5 (20-82) years, and median tumour size was 27 (10-116) mm. Bilateral tumours were more prevalent in ACS (30.0%) and PACS (21.9%) than in NFA (8.1%). Over time, 40/124 (32.3%) patients had a shift of their hormonal secretion pattern (NFA to PACS/ACS, n=15/53; PACS to ACS, n=6/47; ACS to PACS, n=11/24; PACS to NFA, n=8/47). However, none of the patients developed overt Cushing’s syndrome. Sixty-one patients underwent adrenalectomy (NFA, 17.9%; PACS, 24.0%; ACS, 39.0%). When non-operated patients with NFA were compared to PACS and ACS at last follow-up, arterial hypertension (65.3% vs. 81.9% and 92.0%; p<0.05), diabetes (23.8% vs. 35.6% and 40.0%; p<0.01), and thromboembolic events (PACS: HR 3.43, 95%-CI 0.89-13.29; ACS: HR 5.96, 95%-CI 1.33-26.63; p<0.05) were significantly less frequent, along with a trend towards a higher rate of cardiovascular events in case of cortisol autonomy (PACS: HR 2.23, 95%-CI 0.94-5.32; ACS: HR 2.60, 95%-CI 0.87-7.79; p=0.1). Twenty-five (12.6%) of the non-operated patients died, with higher overall mortality in PACS (HR 2.6, 95%-CI 1.0-4.7; p=0.083) and ACS (HR 4.7, 95%-CI 1.6-13.3; p<0.005) compared to NFA. In operated patients, prevalence of arterial hypertension decreased significantly (77.0% at diagnosis to 61.7% at last follow-up; p<0.05). The prevalence of cardiovascular events and mortality did not differ significantly between operated and non-operated patients, whereas thromboembolic events were significantly less frequent in the surgical treatment group. Conclusion Our study confirms relevant cardiovascular morbidity in patients with adrenal incidentalomas (especially those with cortisol autonomy). These patients should therefore be monitored carefully, including adequate treatment of typical cardiovascular risk factors. Adrenalectomy was associated with a significantly decreased prevalence of hypertension. However, more than 30% of patients required reclassification according to repeated dexamethasone suppression tests. Thus, cortisol autonomy should ideally be confirmed before making any relevant treatment decision (e.g. adrenalectomy).

Ultrahigh field magnetic resonance imaging (UHF-MRI) at 7 T field strength is becoming increasingly available for imaging of the heart and, when compared to clinically established field strengths, promises better image quality and image information content, more precise functional analysis, potentially new image contrasts, and as all in-vivo imaging techniques, a reduction of the number of animals per study because of the possibility to scan every animal repeatedly. We present here a solution to the dual use problem of whole-body UHF-MRI systems, which are typically installed in clinical environments, to both UHF-MRI in large animals and humans. Moreover, we provide evidence that in such a research infrastructure UHF-MRI, and ideally combined with a standard small-bore UHF-MRI system, can contribute to a variety of spatial scales in translational cardiovascular research: from cardiac organoids, Zebra fish and rodent hearts to large animal models such as pigs and humans. We present pilot data from serial CINE, late gadolinium enhancement, and susceptibility weighted UHF-MRI in a myocardial infarction model over eight weeks. In 14 pigs which were delivered from a breeding facility in a national SARS-CoV-2 hotspot, we found no infection in the incoming pigs. Human scanning using CINE and phase contrast flow measurements provided good image quality of the left and right ventricle. Agreement of functional analysis between CINE and phase contrast MRI was excellent. MRI in arrested hearts or excised vascular tissue for MRI-based histologic imaging, structural imaging of myofiber and vascular smooth muscle cell architecture using high-resolution diffusion tensor imaging, and UHF-MRI for monitoring free radicals as a surrogate for MRI of reactive oxygen species in studies of oxidative stress are demonstrated. We conclude that UHF-MRI has the potential to become an important precision imaging modality in translational cardiovascular research.

Methods: From 2007 to 2022, a cohort of 255 patients was analyzed for CIED malfunctions via immediate device interrogation after every RT fraction. Results: Out of 324 series of radiotherapy treatments, with a total number of 5742 CIED interrogations, nine device malfunctions (2.8%) occurred. Switching into back-up/safety mode and software errors occurred four times each. Once, automatic read-out could not be performed. The median prescribed cumulative dose at planning target volume (PTV) associated with CIED malfunction was 45.0 Gy (IQR 36.0–64.0 Gy), with a median dose per fraction of 2.31 Gy (IQR 2.0–3.0 Gy). The median maximum dose at the CIED at time of malfunction was 0.3 Gy (IQR 0.0–1.3 Gy). No correlation between CIED malfunction and maximum photon energy (p = 0.07), maximum dose at the CIED (p = 0.59) nor treatment localization (p = 0.41) could be detected. After excluding the nine malfunctions, premature battery depletion was only observed three times (1.2%). Depending on the national guidelines, 1–9 CIED malfunctions in this study would have been detected on the day of occurrence and in none of the cases would patient safety have been compromised. Conclusion: Radiation-induced malfunctions of CIEDs and premature battery depletion are rare. If recommendations of national safety guidelines are followed, only a portion of the malfunctions would be detected directly after occurrence. Nevertheless, patient safety would not be compromised.

We investigated the impact of improved air quality during the economic lockdown during the SARS-Cov2 pandemic on emergency room (ER) admissions in Germany. Weekly aggregated clinical data from 33 hospitals were collected in 2019 and 2020. Hourly concentrations of nitrogen and sulfur dioxide (NO2, SO2), carbon and nitrogen monoxide (CO, NO), ozone (O3) and particulate matter (PM10, PM2.5) measured by ground stations and meteorological data (ERA5) were selected from a 30 km radius around the corresponding ED. Mobility was assessed using aggregated cell phone data. A linear stepwise multiple regression model was used to predict ER admissions. The average weekly emergency numbers vary from 200 to over 1600 cases (total n = 2,216,217). The mean maximum decrease in caseload was 5 standard deviations. With the enforcement of the shutdown in March, the mobility index dropped by almost 40%. Of all air pollutants, NO2 has the strongest correlation with ER visits when averaged across all departments. Using a linear stepwise multiple regression model, 63% of the variation in ER visits is explained by the mobility index, but still 6% of the variation is explained by air quality and climate change.

We investigated whether psychosocial factors such as social support and personal and work-related concerns impact mental health and HRQL differentially in women and men during the first year of the COVID-19 pandemic. Between June and October 2020, the first part of a COVID-19-specific program was conducted within the “Characteristics and Course of Heart Failure Stages A-B and Determinants of Progression (STAAB)” cohort study, a representative age- and gender-stratified sample of the general population of Würzburg, Germany. Using psychometric networks, we first established the complex relations between personal social support, personal and work-related concerns, and their interactions with anxiety, depression, and HRQL. Second, we tested for gender differences by comparing expected influence, edge weight differences, and stability of the networks. The network comparison revealed a significant difference in the overall network structure. The male (N = 1370) but not the female network (N = 1520) showed a positive link between work-related concern and anxiety. In both networks, anxiety was the most central variable. These findings provide further evidence that the complex interplay of psychosocial factors with mental health and HRQL decisively depends on gender. Our results are relevant for the development of gender-specific interventions to increase resilience in times of pandemic crisis.

The current study aimed to determine health-related quality of life (HRQoL) after COVID-19 hospitalization in non-intensive care unit (ICU) and ICU patients. This is a single-center study at the University Hospital of Wuerzburg, Germany. Patients eligible were hospitalized with COVID-19 between March 2020 and December 2020. Patients were interviewed 3 and 12 months after hospital discharge. Questionnaires included the European Quality of Life 5 Dimensions 5 Level (EQ-5D-5L), patient health questionnaire-9 (PHQ-9), the generalized anxiety disorder 7 scale (GAD-7), FACIT fatigue scale, perceived stress scale (PSS-10) and posttraumatic symptom scale 10 (PTSS-10). 85 patients were included in the study. The EQ5D-5L-Index significantly differed between non-ICU (0.78 ± 0.33 and 0.84 ± 0.23) and ICU (0.71 ± 0.27; 0.74 ± 0.2) patients after 3- and 12-months. Of non-ICU 87% and 80% of ICU survivors lived at home without support after 12 months. One-third of ICU and half of the non-ICU patients returned to work. A higher percentage of ICU patients was limited in their activities of daily living compared to non-ICU patients. Depression and fatigue were present in one fifth of the ICU patients. Stress levels remained high with only 24% of non-ICU and 3% of ICU patients (p = 0.0186) having low perceived stress. Posttraumatic symptoms were present in 5% of non-ICU and 10% of ICU patients. HRQoL is limited in COVID-19 ICU patients 3- and 12-months post COVID-19 hospitalization, with significantly less improvement at 12-months compared to non-ICU patients. Mental disorders were common highlighting the complexity of post-COVID-19 symptoms as well as the necessity to educate patients and primary care providers about monitoring mental well-being post COVID-19.

A1 - Gerull, Brenda T1 - Mutations in DNAJC19 cause altered mitochondrial structure and increased mitochondrial respiration in human iPSC-derived cardiomyocytes JF - Molecular Metabolism N2 - Highlights • Loss of DNAJC19's DnaJ domain disrupts cardiac mitochondrial structure, leading to abnormal cristae formation in iPSC-CMs. • Impaired mitochondrial structures lead to an increased mitochondrial respiration, ROS and an elevated membrane potential. • Mutant iPSC-CMs show sarcomere dysfunction and a trend to more arrhythmias, resembling DCMA-associated cardiomyopathy. Background Dilated cardiomyopathy with ataxia (DCMA) is an autosomal recessive disorder arising from truncating mutations in DNAJC19, which encodes an inner mitochondrial membrane protein. Clinical features include an early onset, often life-threatening, cardiomyopathy associated with other metabolic features. Here, we aim to understand the metabolic and pathophysiological mechanisms of mutant DNAJC19 for the development of cardiomyopathy. Methods We generated induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) of two affected siblings with DCMA and a gene-edited truncation variant (tv) of DNAJC19 which all lack the conserved DnaJ interaction domain. The mutant iPSC-CMs and their respective control cells were subjected to various analyses, including assessments of morphology, metabolic function, and physiological consequences such as Ca\(^{2+}\) kinetics, contractility, and arrhythmic potential. Validation of respiration analysis was done in a gene-edited HeLa cell line (DNAJC19tv\(_{HeLa}\)). Results Structural analyses revealed mitochondrial fragmentation and abnormal cristae formation associated with an overall reduced mitochondrial protein expression in mutant iPSC-CMs. Morphological alterations were associated with higher oxygen consumption rates (OCRs) in all three mutant iPSC-CMs, indicating higher electron transport chain activity to meet cellular ATP demands. Additionally, increased extracellular acidification rates suggested an increase in overall metabolic flux, while radioactive tracer uptake studies revealed decreased fatty acid uptake and utilization of glucose. Mutant iPSC-CMs also showed increased reactive oxygen species (ROS) and an elevated mitochondrial membrane potential. Increased mitochondrial respiration with pyruvate and malate as substrates was observed in mutant DNAJC19tv HeLa cells in addition to an upregulation of respiratory chain complexes, while cellular ATP-levels remain the same. Moreover, mitochondrial alterations were associated with increased beating frequencies, elevated diastolic Ca\(^{2+}\) concentrations, reduced sarcomere shortening and an increased beat-to-beat rate variability in mutant cell lines in response to β-adrenergic stimulation. Conclusions Loss of the DnaJ domain disturbs cardiac mitochondrial structure with abnormal cristae formation and leads to mitochondrial dysfunction, suggesting that DNAJC19 plays an essential role in mitochondrial morphogenesis and biogenesis. Moreover, increased mitochondrial respiration, altered substrate utilization, increased ROS production and abnormal Ca\(^{2+}\) kinetics provide insights into the pathogenesis of DCMA-related cardiomyopathy.

We investigated their implementation into real-world HF care in Germany before, during, and after the COVID-19 pandemic period. Methods The IQVIA LRx data set is based on ∼80% of 73 million people covered by the German statutory health insurance. Prescriptions of S/V were used as a proxy for HFrEF. Time trends were analysed between Q1/2016 and Q2/2023 for prescriptions for S/V alone and in combination therapy with SGLT2i. Findings The number of patients treated with S/V increased from 5260 in Q1/2016 to 351,262 in Q2/2023. The share of patients with combination therapy grew from 0.6% (29 of 5260) to 14.2% (31,128 of 219,762) in Q2/2021, and then showed a steep surge up to 54.8% (192,429 of 351,262) in Q2/2023, coinciding with the release of the European Society of Cardiology (ESC) guidelines for HF in Q3/2021. Women and patients aged >80 years were treated less often with combined therapy than men and younger patients. With the start of the COVID-19 pandemic, the number of patients with new S/V prescriptions dropped by 17.5% within one quarter, i.e., from 26,855 in Q1/2020 to 22,145 in Q2/2020, and returned to pre-pandemic levels only in Q1/2021. Interpretation The COVID-19 pandemic was associated with a 12-month deceleration of S/V uptake in Germany. Following the release of the ESC HF guidelines, the combined prescription of S/V and SGLT2i was readily adopted. Further efforts are needed to fully implement GDMT and strengthen the resilience of healthcare systems during public health crises.

Mithilfe der kathetergestützten Aortenklappenimplantation (TAVI) ist es heutzutage möglich, auch chirurgisch inoperable PatientInnen mit einer Klappenprothese zielgerichtet zu behandeln. Ziel dieser Arbeit war es, klinische und echokardiografische Prädiktoren der Gesamtmortalität sowie des Kurz- (30 Tage) und Langzeitüberlebens (12 Monate) nach TAVI zu ermitteln. Es wurden zahlreiche klinische und echokardiografische Parameter bei 618 PatientInnen, die zwischen Juli 2009 und Oktober 2018 eine TAVI erhielten, untersucht. Anschließend erfolgte ein Follow-up mittels Telefoninterview oder hausärztlicher Auskunft. Es folgten statistische Analysen zur Ermittlung signifikanter Unterschiede zwischen verstorbenen und lebenden PatientInnen. Abschließend wurden mögliche Prädiktoren der Mortalität mithilfe multivariabler Cox Regressionmodelle identifiziert. In den Analysen ergaben sich zahlreiche signifikante Unterschiede zwischen Lebenden und Verstorbenen. Klinische Prädiktoren, die ein höheres Risiko der Gesamt- sowie Langzeitmortalität anzeigen, sind der Zugangsweg (transapikal), pAVK, Vorhofflimmern, erhöhte CRP-Level sowie eine Amiodaroneinnahme. Letztere erwies sich als der einzige Prädiktor der Kurzzeitmortalität. Als echokardiografische Prädiktoren (nach Adjustierung bezüglich klinischer Parameter) der Gesamtmortalität präsentieren sich eine erniedrigte TAPSE (≤14mm), erniedrigte septale MAPSE (≤6mm) sowie erhöhtes septales E/e‘ (≥28). Dieses ist auch ein Prädiktor des Lang- und Kurzzeitüberlebens. Zusätzlich zeigt ein sPAP-Anstieg pro 5mmHg eine erhöhte Kurzzeitsterblichkeit an. Für die Mortalität nach einem TAVI-Eingriff sind neben kardiovaskulären Komorbiditäten auch echokardiografisch messbare kardiale Faktoren entscheidend, insbesondere eine systolische Dysfunktion (erniedrigte TAPSE und MAPSE), diastolische Dysfunktion (erhöhter Füllungsdruckindex E/e‘) sowie erhöhte pulmonalarterielle Drücke (sPAP). Wenn PatientInnen schon vor dem Eingriff diese pathologischen Werte zeigen, sind sie als einem „Hochrisikokollektiv“ zugehörig aufzufassen, was in der Aufklärung wie auch Vor- und in der Nachsorge solcher PatientInnen zukünftig Berücksichtigung finden sollte. N2 - Aortic valve stenosis is one of the most common heart valve diseases in the western world with increasing incidence. Due to transcatheter aortic valve implantation (TAVI), it is now possible to treat surgically inoperable patients with a valve prosthesis. The aim of this study was to determine clinical and echocardiographic predictors of overall mortality as well as short- (30 days) and long-term survival (12 months) after TAVI. Numerous clinical and echocardiographic parameters were examined in 618 patients who underwent TAVI between July 2009 and October 2018. Follow-up was carried out by telephone interview or GP information. Statistical analyses were carried out to determine significant differences between deceased and living patients. Finally, possible predictors of mortality were identified using multivariable Cox regression models. The analyses revealed several significant differences between living and deceased patients. Clinical predictors indicating a higher risk of overall and long-term mortality were TAVI approach(transapical), peripheral vascular disease, atrial fibrillation, elevated CRP levels and amiodarone use. The latter proved to be the only predictor of short-term mortality. Reduced TAPSE (≤14mm), reduced septal MAPSE (≤6mm) and increased septal E/e' (≥28) were found to be echocardiographic predictors (after adjustment for clinical parameters) of overall mortality. Latter is also a predictor of long-term and short-term outcome. In addition, increased sPAP (per 5mmHg) indicates higher risk of short-term mortality. In addition to cardiovascular comorbidities, echocardiographically measurable parameters, in particular systolic dysfunction (reduced TAPSE and MAPSE), diastolic dysfunction (increased filling pressure index E/e') and increased pulmonary artery pressure (sPAP), are decisive for mortality post TAVI. If patients already show these pathological values before the procedure, they should be regarded as "high-risk group", which should be taken into account in the education of the patient as well as into their follow up visits.

In einigen Arbeiten wurde bereits die Vordilatation als obsolet bezeichnet, da sie lediglich die OP-Zeit verlängere und Komplikationen wie Schlaganfälle und AV-Blockierungen begünstige.22,52,53,57,59 Ziel dieser Studie war es, die Vor- und Nachteile der Vordilatation zu untersuchen. Hierzu wurden 625 Patienten, die im Zeitraum von 2016-2020 eine TAVI am UKW erhielten, retrospektiv analysiert (323 mit, 302 ohne Vordilatation). Es wurden demographische sowie prä-, peri- und post-interventionelle Daten analysiert. Statistisch signifikante Unterschiede wurden bei den Schlaganfällen beobachtet (p=0,01), die mit 2,2% lediglich bei Patienten mit Vordilatation auftraten, sodass bei einem hohen Schlaganfallrisiko hierauf verzichtet werden sollte. Zusätzlich war in der Gruppe mit Vordilatation die passagere Schrittmacherabhängigkeit signifikant häufiger (p=0,01). Alle anderen Komplikationen waren nicht signifikant. In beiden Gruppen zeigte sich zu >95% ein Device-Success, sodass der Verzicht auf eine Prädilatation nicht mit einem schlechteren Outcome assoziiert und somit sicher ist.53,57,58,59,61 Die Auswertung der TTE-Daten zeigte, dass eine Prädilatation durchgeführt wurde, wenn die Klappe signifikant höhergradig stenosiert war (Pmean 50,17 vs. 46,79mmHG). Ferner wurde bei leichtgradigen Aortenklappeninsuffizienzen signifikant häufiger auf eine Vordilatation verzichtet (p=0,04). Eine Vordilatation kann also bei komplexeren anatomischen Verhältnissen sinnvoll sein, um einen optimalen Klappensitz zu gewährleisten.52,53 Nach TAVI zeigte sich die LV-EF in der Gruppe mit Prädilatation signifikant höher (p=0,002). Höhergradige Aortenklappeninsuffizienzen scheinen nicht durch eine Vordilatation begünstigt zu sein, die AI°II wurde nur bei 4 Patienten ohne Vordilatation beobachtet. In den postinterventionellen EKG-Daten zeigten sich in der Gruppe ohne Vordilatation signifikant häufiger Linksschenkelblöcke sowie ein AVB °II, Typ II, was vermutlich durch die fehlende Vorbereitung der Klappe und den damit assoziierten ungünstigeren Prothesensitz zu erklären ist.53 Die Nachdilatation wurde nicht durch eine vorausgegangene Vordilatation beeinflusst. Bezüglich der implantierten Klappenarten wurde die S3 Ultra signifikant häufiger bei Patienten ohne Vordilatation eingesetzt. Die in vielen Arbeiten beschriebene kürzere OP-Dauer ließ sich in dieser Studie nicht bestätigen.52,53,56 Stattdessen war bei TAVIs ohne Vordilatation die Eingriffsdauer im Schnitt 4min länger (p=0,11). Es bestätigte sich, dass bei einer Prädilatation signifikant mehr Kontrastmittel verwendet wurde (p=0,001) und die Strahlenbelastung höher war. Dies ist insbesondere für Patienten mit einer Niereninsuffizienz von Bedeutung.42 Ob eine Vordilatation durchgeführt wird, sollte also individuell aufgrund der Begleiterkrankungen und Risikofaktoren entschieden werden. N2 - Transcatheter aortic valve implantation is becoming more important for patients with severe aortic stenosis and low surgical risk .45 Therefore it is important to optimize the procedure. Some articles call a predilatation obsolete as the procedural time could be longer and complications such as stroke or AV-blocks would increase.22,52,53,57,59 The aim of this study was to find out whether a predilatation is beneficial. Therefore 625 patients who received a TAVI at the UKW in the time span from 2016-2020 were analysed retrospectively (323 with and 302 without predilatation). The analysis included demographic as well as pre-, peri- and post-procedural data. There was a statistically significant higher risk for a stroke (p=0,01) in the pre-dilatation-group. If a patient has a higher risk for an embolization, predilatation should be surrendered. Additionally, in the pre-dilatation group the necessity for a temporary pacemaker was significantly higher (p=0,01) while other complications were equal. Both groups had a device success rate >95%, thus there should be no inferior outcome without predilatation.53,57,58,59,61 By analysing the TTE-data it could be noticed that a predilatation was done when the stenosis was calcified to a significantly higher level (Pmean 50,17 vs. 46,79 mmHG). A predilatation was not performed when there was a mild aortic-regurgitation (p=0,04). This is why it might be reasonable to perform a predilatation when having complex anatomical proportions.52,53 After TAVI the LV-EF was significantly higher in the predilatation-group (p=0,002). Higher aortic insufficiencies could not be seen. In the group without predilatation four patients had an AI °II. The postinterventional EKG showed significantly more left-bundle-branch-blocks and AVB °II in the group without predilatation. This might be evidence for an unfavourable placement of the valve.53 Post-dilatation was not affected by predilatation. Regarding the different types of valves, it could be found that the S3 Ultra was significantly more often used in the group without predilatation. Some studies reported a shorter procedural time without predilatation. This could not be confirmed.52,53,56 Instead the procedural time was 4 minutes longer without predilatation (p=0,11). With predilatation the use of contrast medium and the radiation exposure was significantly higher (p=0,001), especially for patients with kidney disease this is highly relevant.42 Overall the decision to perform a predilatation is individual, regarding the patient´s diseases and risk factors.

T1 - CXCR4-targeted theranostics in oncology JF - European Journal of Nuclear Medicine and Molecular Imaging N2 - A growing body of literature reports on the upregulation of C-X-C motif chemokine receptor 4 (CXCR4) in a variety of cancer entities, rendering this receptor as suitable target for molecular imaging and endoradiotherapy in a theranostic setting. For instance, the CXCR4-targeting positron emission tomography (PET) agent [\(^{68}\)Ga]PentixaFor has been proven useful for a comprehensive assessment of the current status quo of solid tumors, including adrenocortical carcinoma or small-cell lung cancer. In addition, [\(^{68}\)Ga]PentixaFor has also provided an excellent readout for hematological malignancies, such as multiple myeloma, marginal zone lymphoma, or mantle cell lymphoma. PET-based quantification of the CXCR4 capacities in vivo allows for selecting candidates that would be suitable for treatment using the theranostic equivalent [\(^{177}\)Lu]/[\(^{90}\)Y]PentixaTher. This CXCR4-directed theranostic concept has been used as a conditioning regimen prior to hematopoietic stem cell transplantation and to achieve sufficient anti-lymphoma/-tumor activity in particular for malignant tissues that are highly sensitive to radiation, such as the hematological system. Increasing the safety margin, pretherapeutic dosimetry is routinely performed to determine the optimal activity to enhance therapeutic efficacy and to reduce off-target adverse events. The present review will provide an overview of current applications for CXCR4-directed molecular imaging and will introduce the CXCR4-targeted theranostic concept for advanced hematological malignancies.

Data on recurrence-free survival (RFS) in early and locally advanced pure LCNEC after complete resection (R0) are lacking. This study aims to evaluate clinical outcomes in this subgroup of patients and to identify potential prognostic markers. Methods: Retrospective multicenter study including patients with pure LCNEC stage I-III and R0 resection. Clinicopathological characteristics, RFS, and disease-specific survival (DSS) were evaluated. Univariate and multivariate analyses were performed. Results: 39 patients (M:F = 26:13), with a median age of 64 years (44–83), were included. Lobectomy (69.2%), bilobectomy (5.1%), pneumonectomy (18%), and wedge resection (7.7%) were performed mostly associated with lymphadenectomy. Adjuvant therapy included platinum-based chemotherapy and/or radiotherapy in 58.9% of cases. After a median follow-up of 44 (4–169) months, the median RFS was 39 months with 1-, 2- and 5-year RFS rates of 60.0%, 54.6%, and 44.9%, respectively. Median DSS was 72 months with a 1-, 2- and 5-year rate of 86.8, 75.9, and 57.4%, respectively. At multivariate analysis, age (cut-off 65 years old) and pN status were independent prognostic factors for both RFS (HR = 4.19, 95%CI = 1.46–12.07, p = 0.008 and HR = 13.56, 95%CI 2.45–74.89, p = 0.003, respectively) and DSS (HR = 9.30, 95%CI 2.23–38.83, p = 0.002 and HR = 11.88, 95%CI 2.28–61.84, p = 0.003, respectively). Conclusion: After R0 resection of LCNEC, half of the patients recurred mostly within the first two years of follow-up. Age and lymph node metastasis could help to stratify patients for adjuvant therapy.

Die Prognose ist im Allgemeinen ungünstig und vom Tumorstadium sowie von weiteren tumor- und patientenspezifischen Faktoren abhängig. Die chirurgische Komplettresektion stellt das bisher einzige kurative Behandlungsverfahren dar. Dabei gibt es bisher für sonstige Lokaltherapien beim fortgeschrittenen bzw. rezidivierten ACC kaum umfangreiche Daten, welche die entsprechende lokale Wirksamkeit belegen. Neben der Operation stellt die Strahlentherapie eine bisher effektive Therapieoption bei verschiedenen anderen Tumorerkrankungen hinsichtlich Tumorkontrolle, Verträglichkeit und Zugänglichkeit dar. Allerdings ist diese Option in der Behandlung des fortgeschrittenen ACC als Lokaltherapie bislang nicht mit zufriedenstellenden Datensätzen umfänglich untersucht. Ziel dieser Studie war es, anhand einer retrospektiven Datenanalyse aus dem European Network for the Study of Adrenal Tumours (ENSAT) den Stellenwert der Strahlentherapie als Lokaltherapie beim fortgeschrittenen bzw. rezidivierten ACC zu untersuchen. Es wurden insgesamt 132 Fälle hinsichtlich strahlentherapeutischer Dosis, Lokalkontrolle, progressionsfreiem Überleben, Gesamtüberleben, objektivem Ansprechen, Verträglichkeit und Risikofaktoren untersucht. Hierbei konnte gezeigt werden, dass die Anwendung einer hohen biologischen Effektivdosis mit einer verbesserten lokalen Tumorkontrolle einhergeht. Insgesamt zeigte sich eine gute Verträglichkeit der strahlentherapeutischen Behandlung. Die Ergebnisse dieser Arbeit legen nahe, dass wahrscheinlich weitere Risikofaktoren mit Rezidiven dieser Tumorart einhergehen, allerdings weitere Untersuchungen (z.B. randomisierte prospektive Studien) erfordern. Letztendlich stellt diese Arbeit auch die angewandten Dosis- und Fraktionierungskonzepte der vergangenen Jahrzente bei der Behandlung des ACC dar. N2 - Adrenocortical carcinoma (ACC) is a rare malignancy of the adrenal cortex. The prognosis is generally poor and depends on the tumour stage but also on other tumour- and patient-specific factors. Complete surgical resection might be the only curative treatment option so far. Currently there is no data in a satisfactory extent, proving the local effectiveness for other local therapies in advanced ACC. In addition to surgery, radiotherapy has been described as an effective treatment option for various tumor diseases in terms of tumour control, tolerability and accessibility. However, this option as local therapy in the treatment of advanced ACC has not yet been investigated with satisfactory comprehensive data sets. The aim of this study was a retrospective data analysis from the European Network for the Study of Adrenal Tumors (ENSAT) to investigate the role of radiotherapy as a local therapy in advanced or relapsed ACC. A total of 132 cases were examined with regard to radiotherapy treatment dose, local control, progression free survival, overall survival, objective response, tolerability and other risk factors. It has been shown that the use of a high biological effective dose is associated with improved local tumour control. Overall, the radiotherapy treatment was well tolerated. The results of this study suggest that additional risk factors are probably associated with tumour recurrences but require further investigation (e.g. randomized prospective studies). Finally, this work also presents the dosage and fractionation concepts used over the past decades in the treatment of ACC.

Low levels of vitamin D and reduced bone mineral density (BMD) have been reported in young patients with NF1. However, correlation between vitamin D and NF1 phenotype needs to be elucidated. Aim of this study was to assess vitamin D levels and bone metabolism in NF1 patients, analyzing potential correlations with clinical phenotype. A cross-sectional study was carried out in a monocentric series of NF1 patients, evaluating genotype, clinical phenotype, BMD, biochemical evaluation with focus on serum 25OH-vitamin D, parathyroid hormone (PTH), calcium and phosphate levels. Correlations between clinical manifestations, neurofibromas, and vitamin D status have been studied in comparison with healthy controls. 31 NF1 adult patients were matched for sex, age and body mass index with 31 healthy controls. A significantly difference in vitamin D level emerged in NF1 patients compared to controls. Interestingly low vitamin D levels correlated with a more aggressive phenotype and with a bigger size of neurofibromas. These data underline that vitamin D deficiency/insufficiency may play a role in clinical severity of neurofibromas in patients with NF1, suggesting the need to check bone status and replace vitamin D in these patients.

T1 - Impact of tumor burden on normal organ distribution in patients imaged with CXCR4-targeted [\(^{68}\)Ga]Ga-PentixaFor PET/CT JF - Molecular Imaging and Biology N2 - Background CXCR4-directed positron emission tomography/computed tomography (PET/CT) has been used as a diagnostic tool in patients with solid tumors. We aimed to determine a potential correlation between tumor burden and radiotracer accumulation in normal organs. Methods Ninety patients with histologically proven solid cancers underwent CXCR4-targeted [\(^{68}\)Ga]Ga-PentixaFor PET/CT. Volumes of interest (VOIs) were placed in normal organs (heart, liver, spleen, bone marrow, and kidneys) and tumor lesions. Mean standardized uptake values (SUV\(_{mean}\)) for normal organs were determined. For CXCR4-positive tumor burden, maximum SUV (SUV\(_{max}\)), tumor volume (TV), and fractional tumor activity (FTA, defined as SUV\(_{mean}\) x TV), were calculated. We used a Spearman's rank correlation coefficient (ρ) to derive correlative indices between normal organ uptake and tumor burden. Results Median SUV\(_{mean}\) in unaffected organs was 5.2 for the spleen (range, 2.44 – 10.55), 3.27 for the kidneys (range, 1.52 – 17.4), followed by bone marrow (1.76, range, 0.84 – 3.98), heart (1.66, range, 0.88 – 2.89), and liver (1.28, range, 0.73 – 2.45). No significant correlation between SUV\(_{max}\) in tumor lesions (ρ ≤ 0.189, P ≥ 0.07), TV (ρ ≥ -0.204, P ≥ 0.06) or FTA (ρ ≥ -0.142, P ≥ 0.18) with the investigated organs was found. Conclusions In patients with solid tumors imaged with [\(^{68}\)Ga]Ga-PentixaFor PET/CT, no relevant tumor sink effect was noted. This observation may be of relevance for therapies with radioactive and non-radioactive CXCR4-directed drugs, as with increasing tumor burden, the dose to normal organs may remain unchanged.

However, the evidence for this recommendation is very low. Methods We retrospectively analysed all patients who received RT for advanced ACC in five European centres since 2000. Primary endpoint: time to progression of the treated lesion (tTTP). Secondary endpoints: best objective response, progression-free survival (PFS), overall survival (OS), adverse events, and the establishment of predictive factors by Cox analyses. Results In total, 132 tumoural lesions of 80 patients were treated with conventional RT (cRT) of 50–60 Gy (n = 20) or 20–49 Gy (n = 69), stereotactic body RT of 35–50 Gy (SBRT) (n = 36), or brachytherapy of 12–25 Gy (BT) (n = 7). Best objective lesional response was complete (n = 6), partial (n = 52), stable disease (n = 60), progressive disease (n = 14). Median tTTP was 7.6 months (1.0–148.6). In comparison to cRT\(_{20-49Gy}\), tTTP was significantly longer for cRT\(_{50-60Gy}\) (multivariate adjusted HR 0.10; 95% CI 0.03–0.33; p < 0.001) and SBRT (HR 0.31; 95% CI 0.12–0.80; p = 0.016), but not for BT (HR 0.66; 95% CI 0.22–1.99; p = 0.46). Toxicity was generally mild and moderate with three grade 3 events. No convincing predictive factors could be established. Conclusions This largest published study on RT in advanced ACC provides clear evidence that RT is effective in ACC.

Understandably, compelling evidence for deregulated FGF signaling in the development and progression of different types of tumors continue to emerge and FGFR inhibitors arise as potential targeted therapeutic agents, particularly in tumors harboring aberrant FGFR signaling. There is first evidence of a dual role of the FGF/FGFR system in both organogenesis and tumorigenesis, of which this review aims to provide an overview. FGF-1 and FGF-2 are expressed in the adrenal cortex and are the most powerful mitogens for adrenocortical cells. Physiologically, they are involved in development and maintenance of the adrenal gland and bind to a family of four tyrosine kinase receptors, among which FGFR1 and FGFR4 are the most strongly expressed in the adrenal cortex. The repeatedly proven overexpression of these two FGFRs also in adrenocortical cancer is thus likely a sign of their participation in proliferation and vascularization, though the exact downstream mechanisms are not yet elucidated. Thus, FGFRs potentially offer novel therapeutic targets also for adrenocortical carcinoma, a type of cancer resistant to conventional antimitotic agents.

Methoden: Datengrundlage dieser Arbeit war die German Chronic Kidney Disease (GCKD) Beobachtungsstudie. Eingeschlossen wurden Erwachsene mit GFR 30-60 ml/min/1,73m² oder GFR > 60 ml/min/1,73m² mit offensichtlicher Proteinurie. Ausschlusskriterien waren: nicht-kaukasische Ethnie, Organtransplantation, Malignome und Herzinsuffizienz NYHA IV. Untersuchte kombinierte Endpunkte (EP) waren: 1) 4P-MACE (Herzinfarkt, Schlaganfall, kardiovaskulärer Tod, pAVK-Ereignis) 2) Tod jeglicher Ursache 3) Nierenversagen (Dialyse, Transplantation). Es wurden Cox-Regressionen mit HU, TU, und BMI für jeden EP, adjustiert für Alter, Geschlecht, Nikotinkonsum, Diabetes mellitus, arterielle Hypertonie, LDL-Cholesterin, GFR, Urin-Albumin/Kreatinin Ratio (UACR) und CRP berechnet. Interaktionsterme des jeweiligen Surrogats mit dem Geschlecht wurden eingeschlossen. Ergebnisse: Von den 4537 analysierten Studienteilnehmern, waren 59% Männer mit einem Durchschnittsalter von 60 (±12) Jahren, einer mittleren GFR von 50 (±18) ml/min/1,73m² und einem UACR-Median von 49 (10–374) mg/g. Der mittlere HU war 42,7 (±3,6) cm bei Männern und 37,2 (±3,7) cm bei Frauen, der mittlere TU 107,6 (±13,6) cm bei Männern und 97,0 (±16,3) cm bei Frauen und der mittlere BMI 29,7 (±5,9) kg/m². Die mittlere Beobachtungszeit betrug 6,5 Jahre. Der TU war signifikant mit Tod assoziiert, mit einer HR von 1,014 pro cm (95% KI 1,005–1,024). HU war signifikant mit Tod bei Frauen assoziiert, Interaktionsterm HR 1,080 pro cm (95% KI 1,009–1,155). Der BMI hatte keinen signifikanten Einfluss auf untersuchte EP. Schlussfolgerung: Bei Patienten mit mittel- bis schwergradig eingeschränkter Nierenfunktion steigern ein erhöhter TU (bei beiden Geschlechtern), sowie bei Frauen ein erhöhter HU das Risiko für Tod jeglicher Ursache. N2 - Introduction: Adiposity alters the risk of adverse outcome in chronic kidney disease. This work investigates the prognostic impact of the adiposity measures neck circumference (NC), waist circumference (WC) and body mass index (BMI). Methods: This study is based on data from the prospective observational German Chronic Kidney study which included adults with chronic kidney disease, defined as estimated glomerular filtration rate (GFR) 30–60 ml/min/1.73 m² or GFR > 60 ml/min/1.73 m² with overt proteinuria. Exclusion criteria were non-Caucasian ethnicity, solid organ transplant, active malignancy and heart failure NYHA IV. Investigated composite outcomes were: 1) 4P-MACE (stroke, myocardial infarction, cardiovascular death, peripheral artery disease event) 2) all-cause death 3) kidney failure (dialysis, transplantation). Cox-models for each outcome and adiposity measure, adjusted for age, sex, smoking, diabetes, hypertension, LDL-cholesterol, GFR, urine-albumin-creatinine ratio (UACR) and CRP, were calculated. Interaction terms of adiposity measures with sex were included. Results: Of the 4537 analysed participants, 59% were men with a mean age of 60 (±12) years, a mean GFR of 50 (±18) ml/min/1.73m² and a median UACR of 49 (10–374) mg/g. Mean NC was 42.7 (±3.6) cm in men and 37.2 (±3.7) cm in women, mean WC was 107.6 (±13.6) cm in men and 97.0 ± 16.3 cm in women, mean BMI was 29.7 (±5.9) kg/m². The mean follow-up time was 6.5 years. WC was associated with death, HR 1.014 per cm (95%CI: 1.005–1.024). NC in women was associated with death, interaction HR 1.080 per cm (95%CI: 1.009–1.155). No significant association of the BMI with the analysed outcomes was observed. Conclusion: In patients with moderate to moderately severe chronic kidney disease, WC in both sexes and NC in women were independently associated with death. BMI was not a relevant prognostic factor in these patients.

T1 - Development and preclinical assessment of ROR2-specific CAR-T cells for the treatment of clear cell renal cell carcinoma and multiple myeloma T1 - Entwicklung und präklinische Evaluation ROR2-spezifischer CAR-T Zellen zur Behandlung des klarzelligen Nierenzellkarzinoms und des Multiplen Myeloms N2 - Adoptive immunotherapy using chimeric antigen receptor (CAR)-modified T cells is an effective treatment for hematological malignancies that are refractory to conventional chemotherapy. To address a wider variety of cancer entities, there is a need to identify and characterize additional target antigens for CAR-T cell therapy. The two members of the receptor tyrosine kinase-like orphan receptor family, ROR1 and ROR2, have been found to be overexpressed on cancer cells and to correlate with aggressive cancer phenotypes. Recently, ROR1-specific CAR-T cells have entered testing in phase I clinical trials, encouraging us to assess the suitability of ROR2 as a novel target for CAR-T cell therapy. To study the therapeutic potential of targeting ROR2 in solid and hematological malignancies, we selected two representative cancer entities with high unmet medical need: renal cell carcinoma and multiple myeloma. Our data show that ROR2 is commonly expressed on primary samples and cell lines of clear cell renal cell carcinoma and multiple myeloma. To study the efficacy of ROR2-specific CAR T cell therapy, we designed two CAR constructs with 10-fold binding affinity differences for the same epitope of ROR2. We found both cell products to exhibit antigen-specific anti-tumor reactivity in vitro, including tumor cell lysis, secretion of the effector cytokines interleukin-2 (IL-2) and interferon-gamma (IFNγ), and T cell proliferation. In vivo studies revealed ROR2 specific CAR-T cells to confer durable responses, significant survival benefits and long-term persistence of CAR-expressing T cells. Overall, there was a trend towards more potent anti-tumor efficacy upon treatment with T cells that expressed the CAR with higher affinity for ROR2, both in vitro and in vivo. We performed a preclinical safety and toxicology assessment comprising analyses of ROR2 expression in healthy human and murine tissues, cross-reactivity, and adoptive T cell transfer in immunodeficient mice. We found ROR2 expression to be conserved in mice, and low-level expression was detectable in the male and female reproductive system as well as parts of the gastrointestinal tract. CAR-T cells targeting human ROR2 were found to elicit similarly potent reactivity upon recognition of murine ROR2. In vivo analyses showed transient tissue-specific enrichment and activation of ROR2-specific CAR-T cells in organs with high blood circulation, such as lung, liver, or spleen, without evidence for clinical toxicity or tissue damage as determined by histological analyses. Furthermore, we humanized the CAR binding domain of ROR2-specific CAR-T cells to mitigate the risk of adverse immune reactions and concomitant CAR-T cell rejection. Functional analyses confirmed that humanized CARs retained their specificity and functionality against ROR2-positive tumor cells in vitro. In summary, we show that ROR2 is a prevalent target in RCC and MM, which can be addressed effectively with ROR2-specific CAR-T cells in preclinical models. Our preliminary toxicity studies suggest a favorable safety profile for ROR2-specific CAR-T cells. These findings support the potential to develop ROR2-specific CAR-T cells clinically to obtain cell products with broad utility. N2 - Adoptive Immuntherapie mit T-Zellen, die chimäre Antigenrezeptoren (CAR) exprimieren, ist ein effektiver Behandlungsansatz für Chemotherapie-resistente Blutkrebserkrankungen. Die Übertragung dieses Konzepts auf weitere Krebsarten erfordert die Identifikation und Charakterisierung neuer Zielstrukturen für die CAR-T Zelltherapie. ROR1 und ROR2, die beiden Mitglieder der Familie der Rezeptortyrosinkinase-ähnlichen Orphan-Rezeptoren, werden auf einer Vielzahl von Tumoren überexprimiert und korrelieren mit einer schlechten Prognose und höherer Krebs-Invasivität. Kürzlich konnte ROR1 als Zielstruktur für die CAR-T Zelltherapie bestätigt werden und die Effektivität und Sicherheit ROR1 spezifischer CAR-T Zellen wird derzeit im Rahmen klinischer Phase-I Studien näher untersucht. Aus diesem Grund waren wir daran interessiert, das therapeutische Potenzial ROR2-spezifischer Zelltherapie zu untersuchen. Als Modellsysteme hierfür wählten wir das Nierenzellkarzinom und das Multiple Myelom als repräsentative hämatologische und solide Krebserkrankungen mit hohem medizinischem Bedarf aus. Unsere Daten zeigen, dass ROR2 häufig auf Zelllinien und primären Tumorproben des klarzelligen Nierenzellkarzinoms und des Multiplen Myeloms vorkommt. Um die Effektivität ROR2-spezifischer CAR-T Zellen zu untersuchen, wurden zwei CAR Konstrukte mit zehnfach unterschiedlichen Bindungsaffinitäten für dasselbe Epitop von ROR2 hergestellt. Beide Zellprodukte zeigten hohe, antigen-spezifische Antitumor-Reaktivität in vitro – insbesondere im Hinblick auf Tumorzell-Lyse, Sekretion der Zytokine Interleukin-2 (IL-2) und Interferon gamma (IFNγ) und T-Zell Proliferation. In vivo beobachteten wir langanhaltende Antitumor-Effektivität durch ROR2-spezifische CAR-T Zellen, sowie signifikante Überlebensvorteile und langfristige T-Zell Persistenz. Außerdem beobachteten wir, sowohl in vitro als auch in vivo, einen Trend zu stärkerer Antitumor-Effektivität von T-Zellen, die den CAR mit höherer Affinität für ROR2 exprimierten. Im Rahmen einer präklinischen Toxikologie-Studie analysierten wir die Expression von ROR2 im gesunden Gewebe, die Kreuz-Reaktivität ROR2-spezifischer CAR-T Zellen und deren Sicherheit durch adoptiven T-Zell Transfer in immun-defiziente Mäuse. Unsere Daten zeigen, dass ROR2 in H. sapiens und M. musculus gleichermaßen exprimiert wird und ROR2 Expression war insbesondere in den weiblichen und männlichen Reproduktionsorganen und Teilen des Gastrointestinaltrakts detektierbar. Wir konnten außerdem zeigen, dass CAR-T Zellen, die menschliches ROR2 erkennen, vergleichbare Antitumor-Reaktivität gegen Zellen, die murines ROR2 exprimieren, auslösen. Unsere in vivo Analysen zeigten temporäre Anreicherung und Aktivierung ROR2-spezifischer CAR-T Zellen in gut durchbluteten Geweben, wie Lunge, Leber und Milz, in der Abwesenheit klinischer Anzeichen für Toxizität oder histologisch nachweisbarer Gewebsschädigungen. Um die Risiken immunologischer Nebenwirkungen und die damit einhergehende Abstoßung ROR2-spezifischer CAR-T Zellen zu reduzieren, humanisierten wir die CAR Bindedomäne. Unsere Daten zeigen, dass humanisierte ROR2-spezifische CAR-T Zellen vergleichbare Spezifität und Funktionalität gegen ROR2-positive Tumorzellen in vitro aufweisen. Insgesamt zeigen unsere Daten, dass ROR2 eine häufig auftretende Zielstruktur auf der Oberfläche von RCC und MM Zellen ist und diese in präklinischen Modellen effektiv mittels ROR2-spezifischer CAR-T Zellen adressiert werden kann. Unsere vorläufigen Toxizitätsdaten deuten darauf hin, dass ROR2-spezifische CAR-T Zellen ein vorteilhaftes Sicherheitsprofil aufweisen. Alles in allem unterstützen diese Daten das Potenzial der klinischen Entwicklung ROR2-spezifischer CAR-T Zellen als Zellprodukte mit breit gefächerter Anwendbarkeit.

Although this association is well-established, the factors inducing and accelerating cognitive decline beyond ageing and the intricate causal pathways and multilateral interdependencies involved remain poorly understood. Dysregulated and persistent inflammatory processes have been implicated as potentially causal mediators of the adverse consequences on brain function in patients with cardiac disease. Recent advances in positron emission tomography disclosed an enhanced level of neuroinflammation of cortical and subcortical brain regions as an important correlate of altered cognition in these patients. In preclinical and clinical investigations, the thereby involved domains and cell types of the brain are gradually better characterized. Microglia, resident myeloid cells of the central nervous system, appear to be of particular importance, as they are extremely sensitive to even subtle pathological alterations affecting their complex interplay with neighboring astrocytes, oligodendrocytes, infiltrating myeloid cells, and lymphocytes. Here, we review the current evidence linking cognitive impairment and chronic neuroinflammation in patients with various selected cardiac disorders including the aspect of chronic neuroinflammation as a potentially druggable target.

Ziel der vorliegenden Arbeit war es zum einen, zu untersuchen, ob ein LSB einen signifikanten Einfluss auf die Mortalität und kardiovaskuläre Sterblichkeit bei sowohl HFmrEF- als auch HFrEF-PatientInnen hat und zum anderen, ob es einen Zusammenhang zwischen einem LSB und der Nierenfunktion gibt. Methoden: Unsere retrospektive Studie untersuchte 2152 PatientInnen mit echokardiographisch bestätigter HI, die sich zwischen 2009 und 2017 in der Universitätsklinik Würzburg vorstellten. Das mittleres Alter betrug 69 Jahre (±13 Jahre) und 72,5% der HFmrEF-Gruppe und 75,7% der HFrEF-Gruppe waren männlich. Jeder Patient erhielt ein durchschnittliches Follow-Up-von 25 Monaten (13-39 Monate). Zunächst wurden beide Gruppen direkt bezüglich des Vorhandenseins eines LSB miteinander verglichen. Die mit in die Studie aufgenommenen PatientInnen wurden anschließend in zwei größere Gruppen eingeteilt. Dabei konnten 1011 PatientInnen der HFmrEF-Gruppe zugeteilt werden, 125 PatientInnen mit und 886 ohne LSB. In der HFrEF-Gruppe befanden sich 1141 PatientInnen, 281 mit und 860 ohne LSB. Die HFrEF-Gruppe wurde zudem erneut hinsichtlich der Nierenfunktion aufgeteilt. Von den 1141 HFrEF-PatientInnen wurden 648 in die Gruppe mit erhaltener Nierenfunktion aufgeteilt und 493 HFrEF-PatientInnen in die Gruppe mit eingeschränkter Nierenfunktion. Ergebnisse: In der HFmrEF-Subgruppe zeigten sich keine relevanten Auswirkungen durch das Vorhandensein oder Fehlen eines LSB auf die Gesamtmortalität und die kardiovaskuläre Mortalität. Auch in der HFrEF-Gruppe hatte das Vorhandensein eines LSB keine signifikante Relevanz für die Gesamtmortalität (34,5% vs. 31,6%, p=0,165). Das Risiko an einem kardiovaskulären Ereignis zu versterben war allerdings für HFrEF-PatientInnen mit LSB deutlich höher als für PatientInnen ohne LSB (86,3% vs. 82,2%, p=0,041). Nach Adjustierung von Alter, Geschlecht, BMI, KHK sowie Schlaganfall war der Einfluss eines LSB nicht mehr signifikant. Es zeigte sich jedoch, dass HFrEF-PatientInnen mit LSB und normaler Nierenfunktion eine mehr als zweifach erhöhte kardiovaskuläre Sterblichkeit haben (8,2% vs. 16,2%, p=0,002). Nach dieser Feststellung wurde gesondert auf weitere Komorbiditäten als mögliche Einflussfaktoren eingegangen. Unabhängig von dem Vorhandensein eines LSB hatten PatientInnen mit eingeschränkter Nierenfunktion eine deutlich erhöhte Mortalität verglichen mit PatientInnen ohne Nierendysfunktion. Hingegen beeinflusste ein LSB bei HFrEF-PatientInnen mit erhaltener Nierenfunktion das Überleben deutlich. LSB-PatientInnen mit erhaltener Nierenfunktion verstarben häufiger an einem kardiovaskulären Ereignis als HFrEF-PatientInnen mit normaler Nierenfunktion ohne LSB (86,3% vs. 82,2%, p=0,041). Um diese Untersuchung weiter zu vertiefen, wurde die HFrEF-Gruppe anhand der EF erneut in drei Subgruppen eingeteilt. Hierbei konnte eindeutig festgestellt werden, dass PatientInnen mit LSB, erhaltener Nierenfunktion und einer BLEF ≤ 30% vor Adjustierung von Alter, Geschlecht, BMI, Schlaganfall und KHK signifikant häufiger kardiovaskulär verstarben als PatientInnen ohne LSB. Des Weiteren fiel besonders die Subgruppe mit einer BLEF zwischen 36 und 39% auf. Denn vor Adjustierung der kardiovaskulären Mortalität zeigte sich ein signifikant erhöhte Mortalitätsrate für PatientInnen mit LSB. Nach Adjustierung der Einflussfaktoren war der prozentuale Anteil immer noch erhöht, lediglich nicht mehr signifikant. Somit gibt diese Studie den Anreiz, weitere prospektive Studien mit einem größeren Stichprobenumfang durchzuführen, um diese Annahme zu bestätigen. Zudem sollte in weiteren Studien untersucht werden, ob speziell für HFrEF-PatientInnen mit LSB und einer EF zwischen 36 und 39% eine CRT einen positiven therapeutischen Effekt bringen könnte. N2 - As these and other studies have shown, the prevalence of patients with an left ventricular ejection fraction (LVEF) between 36-49% and a concomitant left bundle branch block (LBBB) should not be underestimated. The aim of the present study was to investigate whether LBBB has a significant impact on mortality and cardiovascular mortality in both heart failure with midrange ejection fraction (HFmrEF) and heart failure with reduced ejection fraction (HFrEF) patients and whether there is an association between LBBB and renal function. Methods: Our retrospective study examined 2152 patients with echocardiographically confirmed heart failure (HI) who presented to the University Hospital of Würzburg between 2009 and 2017. The mean age was 69 years (±13 years) and 72.5% of the HFmrEF group and 75.7% of the HFrEF group were male. Each patient received an average follow-up of 25 months (13-39 months). Initially, both groups were directly compared for the presence of LBBB. The patients included in the study were then divided into two larger groups. A total of 1011 patients were assigned to the HFmrEF group, 125 patients with and 886 without LBBB. There were 1141 patients in the HFrEF group, 281 with and 860 without LBBB. The HFrEF group was also divided again according to renal function. Of the 1141 HFrEF patients, 648 were divided into the group with preserved renal function and 493 HFrEF patients into the group with impaired renal function. Results: In the HFmrEF subgroup, there were no relevant effects of the presence or absence of LBBB on all-cause mortality and cardiovascular mortality. In the HFrEF group, the presence of an LBBB also had no significant relevance for all-cause mortality (34.5% vs. 31.6%, p=0.165). However, the risk of dying from a cardiovascular event was significantly higher for HFrEF patients with LBBB than for patients without LBBB (86.3% vs. 82.2%, p=0.041). After adjustment for age, gender, body mass index, coronary heart disease (CHD) and stroke, the influence of LBBB was no longer significant. However, it was found that HFrEF patients with LBBB and normal renal function had a more than two-fold increase in cardiovascular mortality (8.2% vs. 16.2%, p=0.002). After this finding, further comorbidities were separately discussed as possible influencing factors. Regardless of the presence of LBBB, patients with impaired renal function had a significantly higher mortality rate compared to patients without renal dysfunction. In contrast, an LBBB in HFrEF patients with preserved renal function had a significant impact on survival. LBBB patients with preserved renal function were more likely to die from a cardiovascular event than HFrEF patients with normal renal function without LBBB (86.3% vs. 82.2%, p=0.041). To further investigate this study, the HFrEF group was again divided into three subgroups based on ejection fraction. It was clearly established that patients with LBBB, preserved renal function and a BLEF ≤ 30% before adjustment for age, gender, BMI, stroke and CHD died significantly more frequently from cardiovascular causes than patients without LBBB. Furthermore, the subgroup with a baseline ejection fraction between 36 and 39% was particularly striking. Before adjustment for cardiovascular mortality, the mortality rate for patients with LBBB was significantly higher. After adjustment of the influencing factors, the percentage was still increased, but no longer significantly. This study therefore provides an incentive to conduct further prospective studies with a larger sample size in order to confirm this assumption. In addition, further studies should investigate whether cardiac resynchronization therapy (CRT) could have a positive therapeutic effect specifically for HFrEF patients with LBBB and an EF between 36 and 39%.

T1 - The population comparison index: an intuitive measure to calibrate the extent of impairments in patient cohorts in relation to healthy and diseased populations JF - International Journal of Environmental Research and Public Health N2 - We assume that a specific health constraint, e.g., a certain aspect of bodily function or quality of life that is measured by a variable X, is absent (or irrelevant) in a healthy reference population (Ref0), and it is materially present and precisely measured in a diseased reference population (Ref1). We further assume that some amount of this constraint of interest is suspected to be present in a population under study (SP). In order to quantify this issue, we propose the introduction of an intuitive measure, the population comparison index (PCI), that relates the mean value of X in population SP to the mean values of X in populations Ref0 and Ref1. This measure is defined as PCI[X] = (mean[X|SP] − mean[X|Ref0])/(mean[X|Ref1] − mean[X|Ref0]) × 100[%], where mean[X|.] is the average value of X in the respective group of individuals. For interpretation, PCI[X] ≈ 0 indicates that the values of X in the population SP are similar to those in population Ref0, and hence, the impairment measured by X is not materially present in the individuals in population SP. On the other hand, PCI[X] ≈ 100 means that the individuals in SP exhibit values of X comparable to those occurring in Ref1, i.e., the constraint of interest is equally present in populations SP and Ref1. A value of 0 < PCI[X] < 100 indicates that a certain percentage of the constraint is present in SP, and it is more than in Ref0 but less than in Ref1. A value of PCI[X] > 100 means that population SP is even more affected by the constraint than population Ref1.

The Service Center Medical Informatics (SMI) of the University Hospital Würzburg developed and implemented the smartphone-based mobile application (MA) ukw.mobile1 that uses speech recognition for the point-of-care ordering of radiological examinations. The aim of this study was to examine the usability of the MA workflow for the point-of-care ordering of radiological examinations. All physicians at the Department of Trauma and Plastic Surgery at the University Hospital Würzburg, Germany, were asked to participate in a survey including the short version of the User Experience Questionnaire (UEQ-S) and the Unified Theory of Acceptance and Use of Technology (UTAUT). For the analysis of the different domains of user experience (overall attractiveness, pragmatic quality and hedonic quality), we used a two-sided dependent sample t-test. For the determinants of the acceptance model, we employed regression analysis. Twenty-one of 30 physicians (mean age 34 ± 8 years, 62% male) completed the questionnaire. Compared to the conventional desktop application (DA) workflow, the new MA workflow showed superior overall attractiveness (mean difference 2.15 ± 1.33), pragmatic quality (mean difference 1.90 ± 1.16), and hedonic quality (mean difference 2.41 ± 1.62; all p < .001). The user acceptance measured by the UTAUT (mean 4.49 ± 0.41; min. 1, max. 5) was also high. Performance expectancy (beta = 0.57, p = .02) and effort expectancy (beta = 0.36, p = .04) were identified as predictors of acceptance, the full predictive model explained 65.4% of its variance. Point-of-care mHealth solutions using innovative technology such as speech-recognition seem to address the users’ needs and to offer higher usability in comparison to conventional technology. Implementation of user-centered mHealth innovations might therefore help to facilitate physicians’ daily work.

T1 - Prevalence and prognostic impact of chronic kidney disease and anaemia across ACC/AHA precursor and symptomatic heart failure stages JF - Clinical Research in Cardiology N2 - Background The importance of chronic kidney disease (CKD) and anaemia has not been comprehensively studied in asymptomatic patients at risk for heart failure (HF) versus those with symptomatic HF. We analysed the prevalence, characteristics and prognostic impact of both conditions across American College of Cardiology/American Heart Association (ACC/AHA) precursor and HF stages A–D. Methods and results 2496 participants from three non-pharmacological German Competence Network HF studies were categorized by ACC/AHA stage; stage C patients were subdivided into C1 and C2 (corresponding to NYHA classes I/II and III, respectively). Overall, patient distribution was 8.1%/35.3%/32.9% and 23.7% in ACC/AHA stages A/B/C1 and C2/D, respectively. These subgroups were stratified by the absence ( – ) or presence ( +) of CKD (estimated glomerular filtration rate [eGFR] < 60 mL/min/1.73m2) and anaemia (haemoglobin in women/men < 12/ < 13 g/dL). The primary outcome was all-cause mortality at 5-year follow-up. Prevalence increased across stages A/B/C1 and C2/D (CKD: 22.3%/23.6%/31.6%/54.7%; anaemia: 3.0%/7.9%/21.7%/33.2%, respectively), with concordant decreases in median eGFR and haemoglobin (all p < 0.001). Across all stages, hazard ratios [95% confidence intervals] for all-cause mortality were 2.1 [1.8–2.6] for CKD + , 1.7 [1.4–2.0] for anaemia, and 3.6 [2.9–4.6] for CKD + /anaemia + (all p < 0.001). Population attributable fractions (PAFs) for 5-year mortality related to CKD and/or anaemia were similar across stages A/B, C1 and C2/D (up to 33.4%, 30.8% and 34.7%, respectively). Conclusions Prevalence and severity of CKD and anaemia increased across ACC/AHA stages. Both conditions were individually and additively associated with increased 5-year mortality risk, with similar PAFs in asymptomatic patients and those with symptomatic HF.

Most often, ultrasound is followed by [\(^{99m}\)Tc]-sestamibi scintigraphy, but the value of this approach is disputed. Here, we evaluated the diagnostic approach in patients with surgically treated pHPT in our center with the aim to further refine preoperative diagnostic procedures. Methods A single-center retrospective analysis of patients with pHPT from 01/2005 to 08/2021 was carried out followed by evaluation of the preoperative imaging modalities to localize PA. The localization of the PA had to be confirmed intraoperatively by the fresh frozen section and significant dropping of the intraoperative parathyroid hormone (PTH) levels. Results From 658 patients diagnosed with pHPT, 30 patients were excluded from the analysis because of surgery for recurrent or persistent disease. Median age of patients was 58.0 (13–93) years and 71% were female. Neck ultrasound was carried out in 91.7% and localized a PA in 76.6%. In 23.4% (135/576) of the patients, preoperative neck ultrasound did not detect a PA. In this group, [\(^{99m}\)Tc]-sestamibi correctly identified PA in only 25.4% of patients. In contrast, in the same cohort, the use of [\(^{11}\)C]-methionine or [\(^{11}\)C]-choline PET resulted in the correct identification of PA in 79.4% of patients (OR 13.23; 95% CI 5.24–33.56). Conclusion [\(^{11}\)C]-Methionine or [\(^{11}\)C]-choline PET/CT are superior second-line imaging methods to select patients for a focused surgical approach when previous ultrasound failed to identify PA.

A1 - Seyfried, Florian T1 - Impact of preoperative weight loss achieved by gastric balloon on peri- and postoperative outcomes of bariatric surgery in super-obese patients: a retrospective matched-pair analysis JF - Langenbeck’s Archives of Surgery N2 - Background An intragastric balloon is used to cause weight loss in super-obese patients (BMI > 60 kg/m\(^2\)) prior to bariatric surgery. Whether weight loss from intragastric balloon influences that from bariatric surgery is poorly studied. Methods In this retrospective, single-center study, the effects of intragastric balloon in 26 patients (BMI 69.26 ± 6.81) on weight loss after bariatric surgery (primary endpoint), postoperative complications within 30 days, hospital readmission, operation time, and MTL30 (secondary endpoints) were evaluated. Fifty-two matched-pair patients without intragastric balloon prior to bariatric surgery were used as controls. Results Intragastric balloon resulted in a weight loss of 17.3 ± 14.1 kg (BMI 5.75 ± 4.66 kg/m\(^2\)) with a nadir after 5 months. Surgical and postoperative outcomes including complications were comparable between both groups. Total weight loss was similar in both groups (29.0% vs. 32.2%, p = 0.362). Direct postoperative weight loss was more pronounced in the control group compared to the gastric balloon group (29.16 ± 7.53% vs 23.78 ± 9.89% after 1 year, p < 0.05 and 32.13 ± 10.5% vs 22.21 ± 10.9% after 2 years, p < 0.05), who experienced an earlier nadir and started to regain weight during the follow-up. Conclusion A multi-stage therapeutic approach with gastric balloon prior to bariatric surgery in super-obese patients may be effective to facilitate safe surgery. However, with the gastric balloon, pre-treated patients experienced an attenuated postoperative weight loss with an earlier nadir and earlier body weight regain. This should be considered when choosing the appropriate therapeutic regime and managing patients’ expectations.

T1 - Secondary prevention in diabetic and nondiabetic coronary heart disease patients: insights from the German subset of the hospital arm of the EUROASPIRE IV and V surveys JF - Clinical Research in Cardiology N2 - Background Patients with coronary heart disease (CHD) with and without diabetes mellitus have an increased risk of recurrent events requiring multifactorial secondary prevention of cardiovascular risk factors. We compared prevalences of cardiovascular risk factors and its determinants including lifestyle, pharmacotherapy and diabetes mellitus among patients with chronic CHD examined within the fourth and fifth EUROASPIRE surveys (EA-IV, 2012–13; and EA-V, 2016–17) in Germany. Methods The EA initiative iteratively conducts European-wide multicenter surveys investigating the quality of secondary prevention in chronic CHD patients aged 18 to 79 years. The data collection in Germany was performed during a comprehensive baseline visit at study centers in Würzburg (EA-IV, EA-V), Halle (EA-V), and Tübingen (EA-V). Results 384 EA-V participants (median age 69.0 years, 81.3% male) and 536 EA-IV participants (median age 68.7 years, 82.3% male) were examined. Comparing EA-IV and EA-V, no relevant differences in risk factor prevalence and lifestyle changes were observed with the exception of lower LDL cholesterol levels in EA-V. Prevalence of unrecognized diabetes was significantly lower in EA-V as compared to EA-IV (11.8% vs. 19.6%) while the proportion of prediabetes was similarly high in the remaining population (62.1% vs. 61.0%). Conclusion Between 2012 and 2017, a modest decrease in LDL cholesterol levels was observed, while no differences in blood pressure control and body weight were apparent in chronic CHD patients in Germany. Although the prevalence of unrecognized diabetes decreased in the later study period, the proportion of normoglycemic patients was low. As pharmacotherapy appeared fairly well implemented, stronger efforts towards lifestyle interventions, mental health programs and cardiac rehabilitation might help to improve risk factor profiles in chronic CHD patients.

Objectives PASSPORT-HF is a prospective, randomized, open, multicenter trial evaluating the effects of a hemodynamic-guided, HF nurse-led care approach using the CardioMEMS™ HF-System on clinical end points. Methods and results The PASSPORT-HF trial has been commissioned by the German Federal Joint Committee (G-BA) to ascertain the efficacy of PA pressure-guided remote care in the German health-care system. PASSPORT-HF includes adult HF patients in NYHA functional class III, who experienced an HF-related hospitalization within the last 12 months. Patients with reduced ejection fraction must be on stable guideline-directed pharmacotherapy. Patients will be randomized centrally 1:1 to implantation of a CardioMEMS™ sensor or control. All patients will receive post-discharge support facilitated by trained HF nurses providing structured telephone-based care. The trial will enroll 554 patients at about 50 study sites. The primary end point is a composite of the number of unplanned HF-related rehospitalizations or all-cause death after 12 months of follow-up, and all events will be adjudicated centrally. Secondary end points include device/system-related complications, components of the primary end point, days alive and out of hospital, disease-specific and generic health-related quality of life including their sub-scales, and laboratory parameters of organ damage and disease progression. Conclusions PASSPORT-HF will define the efficacy of implementing hemodynamic monitoring as a novel disease management tool in routine outpatient care.

Ziel der vorliegenden Arbeit war es, Patienten mit Herzinsuffizienz mit erhaltener Pumpfunktion (HFpEF) anhand von elf begleitend zur Herzinsuffizienz vorliegenden Komorbiditäten einer von sechs Phänogruppen zuzuteilen und diese Phänogruppen prognostisch einzuschätzen. Dies wurde nach Vorlage der polytomen latenten Klassenanalyse (poLCA) von David Kao et al., veröffentlicht im Jahr 2015 im European Journal of Heart Failure, durchgeführt. Mithilfe einer poLCA können innerhalb einer Population Subgruppen mit ähnlichen Merkmalsausprägungen identifiziert werden. Die Patienten der vorliegenden Arbeit stammten aus dem Kollektiv des AHF (Acute-Heart-Failure-) Registers der Universitätsklinik Würzburg. Zusätzlich wurde mit denselben elf Variablen eine von der Vergleichspublikation unabhängige poLCA für die Patienten des AHF-Registers erstellt, sowie eine dritte poLCA, die zusätzlich die Höhe des NT-proBNP berücksichtigte. Die Ergebnisse der Arbeit zeigten, dass die poLCA von Kao et al. durchaus auf andere Studienpopulationen übertragen werden kann, um Patienten mit HFpEF im klinischen Alltag mit wenig Aufwand prognostisch einschätzen zu können. Mehr statistisch signifikante Ergebnisse wurden allerdings bei Anwendung einer eigenen poLCA für das AHF-Register erzielt. Die Höhe des NT-proBNP hatte signifikanten Einfluss auf die Prognose und Klassenzuteilung eines Patienten. N2 - In the context of heart failure, comorbidities accompanying the condition have a decisive impact on the course of the disease, as well as on the treatment and prognosis of such patients. The aim of this study was to allocate patients with heart failure with preserved ejection fraction (HFpEF) into on of six phenogroups based on eleven comorbidities accompanying heart failure, and to assess the prognostic implications of these phenogroups. This was done using polytomous latent class analysis (poLCA) as proposed by David Kao et al., published in 2015 in the European Journal of Heart Failure. PoLCA helps to identify subgroups with similar characteristic patterns within a population. The patients in this study were sourced from the Acute-heart-Failure (AHF) registry at the University Hospital Würzburg. Additionally, an independent poLCA for the AHF-Registry patients was conducted using the same eleven variables, along with a third poLCA that considered the level of NT-proBNP. The results of the study indicated that Kao et al.’s poLCA could be applied to other study populations for the prognostic assessment of HFpEF patients in clinical practice with minimal effort. However, more statistically significant results were obtained when using a custom poLCA for the AHF Registry. The level of NT-proBNP significantly influenced the prognosis and classification allocation of a patient.

Compared with unilateral adrenalectomy (for adrenal Cushing’s syndrome), bilateral adrenalectomy has a perceived higher perioperative morbidity. The aim of the current study was to compare both interventions in endogenous Cushing’s syndrome regarding postoperative outcomes. Methods We report a single-center, retrospective cohort study comparing patients with hypercortisolism undergoing bilateral vs. unilateral adrenalectomy during 2008–2021. Patients with adrenal Cushing’s syndrome due to adenoma were compared with patients with ACTH-dependent Cushing’s syndrome (Cushing’s disease and ectopic ACTH production) focusing on postoperative morbidity and mortality as well as long-term survival. Results Of 83 patients with adrenalectomy for hypercortisolism (65.1% female, median age 53 years), the indication for adrenalectomy was due to adrenal Cushing’s syndrome in 60 patients (72.2%; 59 unilateral and one bilateral), and due to hypercortisolism caused by Cushing’s disease (n = 16) or non-pituitary uncontrolled ACTH secretion of unknown origin (n = 7) (27.7% of all adrenalectomies). Compared with unilateral adrenalectomy (n = 59), patients with bilateral adrenalectomy (n = 24) had a higher rate of severe complications (0% vs. 33%; p < 0.001) and delayed recovery (median: 10.2% vs. 79.2%; p < 0.001). Using the MTL30 marker, patients with bilateral adrenalectomy fared worse than patients after unilateral surgery (MTL30 positive: 7.2% vs. 25.0% p < 0.001). Postoperative mortality was increased in patients with bilateral adrenalectomy (0% vs. 8.3%; p = 0.081). Conclusion While unilateral adrenalectomy for adrenal Cushing’s syndrome represents a safe and definitive therapeutic option, bilateral adrenalectomy to control ACTH-dependent extra-adrenal Cushing’s syndrome or Cushing’s disease is a more complicated intervention with a mortality of nearly 10%.
