  abstract  = {Background: Adrenocortical carcinoma (ACC) is a rare tumor entity with restricted therapeutic opportunities. HSP90 (Heat Shock Protein 90) chaperone activity is fundamental for cell survival and contributes to different oncogenic signaling pathways. Indeed, agents targeting HSP90 function have shown therapeutic efficacy in several cancer types. We have examined the expression of HSP90 in different adrenal tumors and evaluated the use of HSP90 inhibitors in vitro as possible therapy for ACC. Methods: Immunohistochemical expression of HSP90 isoforms was investigated in different adrenocortical tumors and associated with clinical features. Additionally, a panel of N-terminal (17-allylamino-17-demethoxygeldanamycin (17-AAG), luminespib, and ganetespib) and C-terminal (novobiocin and silibinin) HSP90 inhibitors were tested on various ACC cell lines. Results: Within adrenocortical tumors, ACC samples exhibited the highest expression of HSP90β. Within a cohort of ACC patients, HSP90β expression levels were inversely correlated with recurrence-free and overall survival. In functional assays, among five different compounds tested luminespib and ganetespib induced a significant decrease in cell viability in single as well as in combined treatments with compounds of the clinically used EDP-M scheme (etoposide, doxorubicin, cisplatin, mitotane). Inhibition of cell viability correlated furthermore with a decrease in proliferation, in cell migration and an increase in apoptosis. Moreover, analysis of cancer pathways indicated a modulation of the ERK1/2—and AKT—pathways by luminespib and ganetespib treatment. Conclusions: Our findings emphasize HSP90 as a marker with prognostic impact and promising target with N-terminal HSP90 inhibitors as drugs with potential therapeutic efficacy toward ACC.},

  abstract  = {Der prim{\"a}re Hyperaldosteronismus (PA) stellt aktuell den h{\"a}ufigsten Grund f{\"u}r das Vorliegen einer sekund{\"a}ren Hypertonie dar. Der in der Best{\"a}tigungsdiagnostik verwendete Kochsalzbelastungstest basiert dabei auf einem fehlenden Absinken der Aldosteronkonzentration im Testverlauf bei Patient:innen mit PA im Vergleich zu Patient:innen mit essentieller Hypertonie (EH). Die Konzentrationsbestimmung erfolgte bisher mittels Immunoassay. Mit der LC-MS/MS steht jedoch mittlerweile eine weitere wichtige analytische Methode in der quantitativen Bestimmung von Steroidhormonen zur Verf{\"u}gung, welche in dieser Arbeit im Hinblick auf den Kochsalzbelastungstest untersucht wurde. Hohe Bedeutung kommt außerdem der Subtypdifferenzierung des PA zu, da die {\"A}tiologie der Erkrankung wegweisend f{\"u}r die Art der Therapie ist. Das Ziel dieser Studie war einerseits die Ermittlung eines LC-MS/MS-spezifischen Aldosteron-Cut-off-Wertes im Kochsalzbelastungstest und die Evaluation des Nutzens der Bestimmung von Steroidprofilen in der Diagnostik des PA. Zum anderen wurde der diagnostische Nutzen des Orthostasetests zur Unterscheidung von unilateraler und bilateraler Genese bei vorliegendem PA untersucht. Im Rahmen dieser Studien wurden 187 bzw. 158 Patient:innen analysiert, die zwischen 2009 und 2019 bei Verdacht auf oder Vorliegen eines PA im Universit{\"a}tsklinikum W{\"u}rzburg vorstellig wurden. Die Diagnose wurde gem{\"a}ß der aktuellen Leitlinie anhand der Ergebnisse des Kochsalzbelastungstests, NNVKs, Bildgebung und postoperativen Outcomes gestellt. Mithilfe der LC-MS/MS wurden erneut die Aldosteronkonzentrationen der aufbewahrten Serumproben des Kochsalzbelastungstests, sowie ein erweitertes Steroidpanel bestimmt. Unter Verwendung einer ROC-Analyse wurden die jeweils bestehenden Cut-off-Werte optimiert bzw. neu ermittelt. Die mittels Immunoassay bestimmten Aldosteronkonzentrationen lagen um 28 ng/L h{\"o}her als die mittels LC-MS/MS bestimmten Konzentrationen. Trotzdem lag der neu ermittelte LC-MS/MS-spezifische Aldosteron-Cut-off-Wert f{\"u}r den Kochsalzbelastungstest bei 69 ng/L und damit h{\"o}her als der f{\"u}r den Immunoassay geltende, optimierte Aldosteron-Cut-off von 54 ng/L. Unter Verwendung des LC-MS/MS- spezifischen Cut-off-Werts erreichte der Kochsalzbelastungstest eine Sensitivit{\"a}t von 78,6\% bei einer Spezifit{\"a}t von 89,3\%. Die Sensitivit{\"a}t des Immunoassay-spezifischen Cut-off-Werts betrug 95,2\% bei einer Spezifit{\"a}t von 86,9\%. Das Bestimmen des gesamten Steroidprofils f{\"u}hrte zu keiner zus{\"a}tzlichen diagnostischen Information bei Durchf{\"u}hrung des Kochsalzbelastungstests. Bei Betrachtung der gesamten Patient:innenkohorte erreichte der Orthostasetest, basierend auf einem Absinken der Plasmaaldosteronkonzentration nach 4h in Orthostase um ≥ 28\% eine Sensitivit{\"a}t von 36,7\% bei einer Spezifit{\"a}t von 100\%. Wurde das Vorliegen eines g{\"u}ltigen Tests (Cortisolabfall nach 4h ≥ 10\%) oder das Vorliegen einer unilateralen Raumforderung in der Bildgebung vorausgesetzt, stieg die Sensitivit{\"a}t des Orthostasetests auf 51,4\% bzw. 51,6\% bei gleichbleibend hoher Spezifit{\"a}t von 100\% an. Abschließend l{\"a}sst sich sagen, dass der Orthostasetest keine Alternative zum NNVK darstellt, jedoch als einfache, nicht invasive Methode der zus{\"a}tzlichen Orientierung zur Untersuchung der {\"A}tiologie des PAs dienen kann. Eine prospektive Evaluation der jeweils neu ermittelten Cut-off-Werte wird notwendig sein, um deren Anwendbarkeit im klinischen Alltag zu {\"u}berpr{\"u}fen. Außerdem k{\"o}nnte die Bestimmung der Hybridsteroide 18-Oxocortisol und 18-Hydroxycortisol wegweisend f{\"u}r die Genese des PA sein.},

  abstract  = {In diese monozentrische retrospektive Studie eingeschlossen wurden insgesamt 132 Patienten mit Schock, darunter 75 Patienten mit kardiogenem- und 57 Patienten mit septischem Schock. Um potentielle Pr{\"a}diktoren f{\"u}r die Krankenhaussterblichkeit zu finden, wurden folgende Paramater untersucht: Alter, Geschlecht, BMI, kardiovaskul{\"a}re Risikofaktoren und Vorerkrankungen, Vitalparameter bei Aufnahme inkl. Schockindex, laborchemische Parameter inkl. BGA, maximaler Laktatanstieg im Verlauf, Interventionen inklusive Reanimation, Beatmung, Akutrevaskularisation und Anlage von mechanischen Kreislaufunterst{\"u}tzungssystemen, Katecholamintherapie und h{\"a}modynamisches Monitoring mit dem PiCCO-Verfahren. Hauptergebnis unserer Studie ist eine erhebliche Krankenhaussterblichkeit von 50\% bei einem mittleren Aufenthalt von 14 Tagen ohne signifikanten Unterschied zwischen kardiogenem- (45\%) und septischem Schock (55\%), obgleich Patienten mit kardiogenem Schock signifikant {\"a}lter und h{\"a}ufiger kardiovaskul{\"a}r vorerkrankt waren. Pr{\"a}diktoren f{\"u}r die Krankenhaussterblichkeit waren bei Patienten mit kardiogenem Schock die H{\"o}he des maximalen Laktatanstiegs, das Auftreten eines akuten Nierenversagens, die H{\"o}he der Transaminasen als Marker einer Schockleber, die fehlende M{\"o}glichkeit einer Akutrevaskularisation und die H{\"o}he des Troponins als Marker f{\"u}r das Ausmaß des Myokardschadens. Pr{\"a}diktoren f{\"u}r die Krankenhaussterblichkeit im septischen Schock waren ebenfalls die H{\"o}he des maximalen Laktatanstiegs, die Notwendigkeit einer Reanimation, sowie H{\"o}he des ELWI. Die {\"u}brigen klinischen, laborchemischen und h{\"a}modynamischen Parameter waren weder beim kardiogenen- noch beim septischen Schock pr{\"a}diktiv f{\"u}r die Mortalit{\"a}t. Die beste Strategie zur Senkung der hohen Mortalit{\"a}t beider Schockformen besteht in der Prophylaxe des jeweiligen Schockgeschehens.

Bei Patienten mit septischem Schock ist insbesondere bei pneumogener Sepsis das rechtzeitige Erkennen und die Therapie eines ARDS eine bleibende Herausforderung. Zuk{\"u}nftige Studien an gr{\"o}ßeren Patientenkollektiven m{\"u}ssen kl{\"a}ren, ob die Bestimmung des ELWI mit dem PiCCO-Verfahren hilfreich ist, die Entstehung eines ARDS fr{\"u}hzeitig erkennen und behandeln zu k{\"o}nnen.},

  abstract  = {We previously identified peptides that are actively transported across the intact tympanic membrane (TM) of rats with infected middle ears. To assess the possibility that this transport would also occur across the human TM, we first developed and validated an assay to evaluate transport in vitro using fragments of the TM. Using this assay, we demonstrated the ability of phage bearing a TM-transiting peptide to cross freshly dissected TM fragments from infected rats or from uninfected rats, guinea pigs and rabbits. We then evaluated transport across fragments of the human TM that were discarded during otologic surgery. Human trans-TM transport was similar to that seen in the animal species. Finally, we found that free peptide, unconnected to phage, was transported across the TM at a rate comparable to that seen for peptide-bearing phage. These studies provide evidence supporting the concept of peptide-mediated drug delivery across the intact TM and into the middle ears of patients.},

  abstract  = {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.},

  abstract  = {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.},

  abstract  = {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.},

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.},

  abstract  = {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.

  abstract  = {Adrenal insufficiency (AI) is a life-threatening condition requiring life-long glucocorticoid (GC) substitution therapy, as well as stress adaptation to prevent adrenal crises. 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.},

  abstract  = {Objective Immune checkpoint inhibitors can cause various immune-related adverse events including secondary hypophysitis. 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.},

  abstract  = {Background: Monitoring the vital signs of delirious patients in an intensive care unit (ICU) is challenging, as they might (un-)intentionally remove devices attached to their bodies. 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, Gr{\"u}nwald, 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 \&lt; 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.},

  abstract  = {Adrenocortical carcinoma (ACC) represents a rare tumor entity with limited treatment options and usually rapid tumor progression in case of metastatic disease. 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.},

  abstract  = {Sodium-glucose transport protein 2 inhibitors (SGLT2i) slow the progression of renal dysfunction and improve the prognosis of patients with heart failure. 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.},

  abstract  = {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, W{\"u}rzburg 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.

Ebenfalls untersuchten wir, ob es bestimmte echokardiographische Pr{\"a}diktoren f{\"u}r 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 W{\"u}rzburg zwischen Januar 2011 und Dezember 2016 sowohl eine TTE als auch eine DSE durchgef{\"u}hrt. 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 fr{\"u}hestens 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 unabh{\"a}ngiger Pr{\"a}diktor f{\"u}r eine TS-LGAS bei Patienten mit erhaltener und reduzierter LVEF. Eine verringerte MAPSE und eine reduzierte TDI-s´ sprechen bei Patienten mit erhaltener LVEF f{\"u}r eine TS-LGAS. Bei Patienten mit reduzierter LVEF weisen ein erh{\"o}hter sPAP und eine verringerte AV Geschwindigkeits Ratio auf eine TS-LGAS hin. Bei Zweifeln k{\"o}nnen weitere bildgebende Verfahren zur Diagnosefindung hinzugezogen werden.},
