  abstract  = {Background Guideline-directed medical therapy (GDMT) is the cornerstone in the treatment of patients with heart failure and reduced ejection fraction (HFrEF) and novel substances such as sacubitril/valsartan (S/V) and sodium-glucose co-transporter-2 inhibitors (SGLT2i) have demonstrated marked clinical benefits. 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.},

  abstract  = {Objectives The spectrum of giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) represents highly inflammatory rheumatic diseases. 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.},

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.},

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.},

  abstract  = {Morbus Fabry ist eine X-chromosomal vererbte lysosomale Speichererkrankung, die mit einer verminderten Aktivit{\"a}t der -Galaktosidase A einhergeht. Daraus resultiert ein gest{\"o}rter Abbau von Globotriaosylceramiden, die sich im Gewebe verschiedener Organsysteme einlagern und diese funktionell beeintr{\"a}chtigen. Klinisch ist die renale, kardiovaskul{\"a}re und neurologische Beteiligung von besonderer Relevanz. Das W{\"u}rzburger Fabry-Zentrum (FAZiT) hat als eine der {\"a}ltesten Spezial-Einrichtungen zur Betreuung von Menschen mit Morbus Fabry in Deutschland Zugriff auf einen sich {\"u}ber 18 Jahre erstreckenden und 298 Patienten beinhaltenden Datensatz. In dieser Arbeit wurde ein großes Fabry-Kollektiv zun{\"a}chst im Hinblick auf Fabry spezifische Betreuung und aktuelle institutionelle Anbindung untersucht. In diesem Zusammenhang konnte in vier bisher nicht bekannten F{\"a}llen der Tod eines Patienten dokumentiert werden. Anschließend erfolgte in einem Kollektiv von 187 Patienten eine statistische Darstellung definierter klinischer Basisparameter, sowie des Fabry-spezifischen klinischen Erscheinungsbildes, mit Schwerpunkt auf der kardialen Beteiligung. Mit speziellen Subgruppenanalysen wurden Verlaufsunterschiede zwischen lebendenden und bereits verstorbenen Patienten, sowie geschlechts- und genetisch bedingten Charakteristika dargestellt. Von 187 Patienten verstarben 26 innerhalb von 18 Jahren trotz Fabry-spezifischer Therapie in 84\% der F{\"a}lle. Die H{\"a}lfte der Todesf{\"a}lle hatte eine kardiale Genese. Es wurde kein Todesfall mit renaler Genese dokumentiert. Die im FAZiT betreuten verstorbenen Patienten unterschritten das von Waldek et al.25 prognostizierte Sterbealter f{\"u}r Fabry-Patienten. Die Annahme, dass Fabry-Patienten eine, verglichen mit der Normalbev{\"o}lkerung, reduzierte Lebenserwartung haben ließ sich in diesem Kollektiv best{\"a}tigen. Signifikante Unterschiede kardialer Parameter, die auf eine Kardiomyopathie schließen lassen, ließen sich zwischen Frauen und M{\"a}nnern, sowie zwischen Frauen mit klassischer und nicht-klassischer Verlaufsform darstellen. Entgegen der Erwartung zeigten sich hier keine signifikanten Unterschiede zwischen M{\"a}nnern mit klassischer und M{\"a}nnern mit nicht-klassischer Verlaufsform. Eine Erkl{\"a}rung hierf{\"u}r k{\"o}nnte das Vorliegen der N215S-Mutation in 55,6\% in der Subgruppe der M{\"a}nner mit nicht-klassischer Verlaufsform, die trotz nicht-klassischer Verlaufsform mit einer starken kardialen Beeintr{\"a}chtigung einhergeht, sein. Alle untersuchten Fabry-Patienten wiesen im altersabh{\"a}ngigen Vergleich mit der Normalbev{\"o}lkerung eine erh{\"o}hte KHK-Pr{\"a}valenz auf, die nicht eindeutig mit einer Erh{\"o}hung der kardiovaskul{\"a}ren Risikofaktoren erkl{\"a}rbar ist. Auffallend h{\"a}ufig waren die verstorbenen Fabry-Patienten mit einer Pr{\"a}valenz von 30,8\% betroffen. Supportiv sowie das kardiovaskul{\"a}re Risiko beeinflussende Medikamente wurden ebenfalls dokumentiert, wobei unterschiedliche potenzielle Indikationsstellungen einen R{\"u}ckschluss auf die klinische Symptomatik der Patienten verhindern. In dieser Arbeit konnte ein besonders großes Kollektiv an Menschen mit Morbus Fabry {\"u}ber einen langen Zeitraum nachbeobachtet werden. Insbesondere die Gegen{\"u}berstellung von lebenden und verstorbenen Probanden, als auch die Verlaufs-/ und geschlechtsspezifischen Subgruppenvergleiche stellen eine Besonderheit dar. Vor allem bei chronisch erkrankten Menschen sind eine lebenslange Betreuuung und Begleitung der Krankheit von h{\"o}chster Relevanz. Aus diesem Grund k{\"o}nnten die Auswertung der in dieser Arbeit erhobenen Daten und Erkenntnisse zur Verbesserung der zuk{\"u}nftigen Betreuung und Therapie von Menschen mit Morbus Fabry beitragen.},

  abstract  = {Die Rolle des Immunsystems nach MI hat innerhalb der letzten Jahrzehnte immer mehr Aufmerksamkeit erfahren, trotzdem herrschen weiterhin einige Unklarheiten. Daher war es Ziel dieser Arbeit, das Verhalten der T-Zellen nach MI im Mausmodell n{\"a}her zu betrachten und zu analysieren. Daf{\"u}r wurde einerseits mittels Durchflusszytometrie die T-Zell-Immunantwort im Herzen und in verschiedenen lymphatischen Organen mit Fokus auf pro- und antiinflammatorische Zytokine und deren Transkriptionsfaktoren genauer analysiert und andererseits ein Protokoll etabliert, um die T-Zellen im Herzen und in den Lymphknoten mittels Lichtblattmikroskopie sichtbar zu machen. Dabei konnte festgestellt werden, dass die Expression von LAP, welches nicht-kovalent an das antiinflammatorische Zytokin TGF-ß1 gebunden ist und das wichtig f{\"u}r eine ausgeglichene Immunantwort ist, indem es {\"u}berschießende Entz{\"u}ndungsreaktionen verhindert, in T-Zellen im Herzen nach MI im Vergleich zu naiven und scheinoperierten M{\"a}usen signifikant hochreguliert war. Dieses Ergebnis konnte nur im Herzen und in keinem anderen der untersuchten Organe erzielt werden, weshalb es sich somit um eine lokale Immunreaktion handeln muss, die nur im Herzen nach MI stattfindet. Eine weitere Besonderheit war, dass die H{\"a}ufigkeit des Vorkommens an Foxp3+ Treg im Herzen im Vergleich zu den anderen untersuchten Organen durchgehend am h{\"o}chsten war, sowohl bei den M{\"a}usen nach MI als auch bei naiven und scheinoperierten M{\"a}usen. Dies unterstreicht, dass Foxp3+ Treg im Herzen eine wichtige Rolle spielen. Dank der Verbesserung des Protokolls zur bildlichen Darstellung von T-Zellen im Herzen konnte gezeigt werden, dass sich diese nach MI insbesondere im Infarktgewebe befinden und dort relativ gleichm{\"a}ßig verteilt sind. Außerdem konnten die mediastinalen Lymphknoten im Ganzen dargestellt und die einzelnen T-Zellen sichtbar gemacht werden. Insgesamt l{\"a}sst sich sagen, dass durch die vorliegende Arbeit neue Erkenntnisse zur Charakterisierung der T-Zell-Immunantwort nach MI im Mausmodell hinzugewonnen werden konnten. Die LAP+ T-Zellen scheinen nach MI im Herzen eine wichtige Rolle zu spielen, weshalb die Funktion dieser Zellen im Reparaturprozess nach MI in zuk{\"u}nftigen Versuchen genauer betrachtet werden sollte. Außerdem wurde der Grundstein zur Anf{\"a}rbung und Darstellung von T-Zellen in Herzen und in Lymphknoten mittels Lichtblattmikroskopie gelegt, weshalb daran weitergearbeitet werden sollte, um auch andere Immunzellen neben den T-Zellen zeigen zu k{\"o}nnen. Dadurch k{\"o}nnen weitere Hinweise auf das Zusammenspiel der Immunzellen nach MI erhalten werden, um die immunologischen Vorg{\"a}nge immer besser verstehen zu k{\"o}nnen.},

  abstract  = {Although bariatric surgery is known to change the metabolome, it is unclear if this is specific for the intervention or a consequence of the induced bodyweight loss. As the weight loss after Roux-en-Y Gastric Bypass (RYGB) can hardly be mimicked with an evenly effective diet in humans, translational research efforts might be helpful. A group of 188 plasma metabolites of 46 patients from the randomized controlled W{\"u}rzburg Adipositas Study (WAS) and from RYGB-treated rats (n = 6) as well as body-weight-matched controls (n = 7) were measured using liquid chromatography tandem mass spectrometry. WAS participants were randomized into intensive lifestyle modification (LS, n = 24) or RYGB (OP, n = 22). In patients in the WAS cohort, only bariatric surgery achieved a sustained weight loss (BMI -34.3\% (OP) vs. -1.2\% (LS), p ≤ 0.01). An explicit shift in the metabolomic profile was found in 57 metabolites in the human cohort and in 62 metabolites in the rodent model. Significantly higher levels of sphingolipids and lecithins were detected in both surgical groups but not in the conservatively treated human and animal groups. RYGB leads to a characteristic metabolomic profile, which differs distinctly from that following non-surgical intervention. Analysis of the human and rat data revealed that RYGB induces specific changes in the metabolome independent of weight loss.},

  abstract  = {Purpose: This study analyses a large number of cancer patients with CIEDs for device malfunction and premature battery depletion by device interrogation after each radiotherapy fraction and compares different guidelines in regard to patient safety. 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 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 W{\"u}rzburg, 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.},

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.},

  abstract  = {Long-term sequelae in hospitalized Coronavirus Disease 2019 (COVID-19) patients may result in limited quality of life. 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.},

  abstract  = {A key step in translational cardiovascular research is the use of large animal models to better understand normal and abnormal physiology, to test drugs or interventions, or to perform studies which would be considered unethical in human subjects. 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.},

  abstract  = {Background Adrenal incidentalomas with cortisol autonomy are associated with increased cardiovascular morbidity and mortality. 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).},

  abstract  = {Objective: Patients with adrenal insufficiency (AI) need to adapt their glucocorticoid replacement under stressful conditions to prevent adrenal crisis (AC). Prednisone (PN) suppositories are used for emergency treatment. Pharmacokinetics of 100 mg PN suppositories after vaginal or rectal administration was evaluated. Design: Single-center, open-label, sequence-randomized, cross-over, bioequivalence study. Methods: Twelve females with primary AI were included. Comparison of pharmacokinetics after vaginal and rectal administration of 100 mg PN suppositories. Main outcome measures: bioequivalence (Cmax: maximum plasma concentration of prednisolone; AUC0-360: area under the plasma concentration curve of prednisolone from administration to 360 min), adrenocorticotropin (ACTH) levels, safety and tolerability. Comparison of ACTH-suppressive effect with subcutaneous and intramuscular administration of 100 mg hydrocortisone. Results: Vaginal administration of PN suppositories was not bioequivalent to rectal administration: Cmax and AUC0-360 were significantly lower after vaginal compared to rectal administration: 22 ng/mL (109\%) vs 161 ng/mL (28\%), P < 0.001; 4390 ng/mL * min (116\%) vs 40,302 ng/mL * min (26\%), P < 0.001; (mean (coefficient of variation), respectively). A suppression of ACTH by >50\% of baseline values was observed 149 min (32\%) after rectal PN administration; after vaginal PN administration, the maximum decrease within 360 min was only 44\%. Adverse events were more frequent after vaginal administration and mainly attributable to the glucocorticoid deficit due to inadequate vaginal absorption. The ACTH-suppressive effect was more pronounced after parenteral hydrocortisone compared to rectal or vaginal PN. Conclusion: Vaginal administration of PN suppositories in the available form is not useful for prevention of AC. Pharmacokinetics after rectal use of PN show inferiority compared to available data on parenteral glucocorticoids. In adrenal emergencies, hydrocortisone injection should be the first choice.},

Methoden In diese Studie wurden 1355 IHF-Patienten mit einer Ejektionsfraktion <50\% aufgenommen, die mittlere klinische Nachbeobachtungszeit betrug 25 Monate. Mit Hilfe multivariabler Cox-Hazard-Modelle wurden die Zusammenh{\"a}nge zwischen echokardiographischen Variablen [einschließlich 13 Standardparameter und globaler longitudinaler Dehnung (GLS)] und den wichtigsten unerw{\"u}nschten Ergebnissen [einschließlich Gesamtmortalit{\"a}t, kardiovaskul{\"a}rem Tod und kardiovaskul{\"a}r bedingten Krankenhausaufenthalten] bewertet. Ergebnisse Die Gesamtmortalit{\"a}t, die kardiovaskul{\"a}re Mortalit{\"a}t und das kombinierte Risiko f{\"u}r kardiovaskul{\"a}re Ereignisse, einschließlich Tod und Krankenhausaufenthalt, betrugen 29,2 \%, 18,2 \% bzw. 41,1 \%. Rechtsventrikul{\"a}rer mittlerer Hohlraumdurchmesser (RVD) >38 mm, systolische Exkursion der mitralen Anularebene (MAPSE) <8 mm, systolische Exkursion der Trikuspidalebene (TAPSE) <12 mm, Verh{\"a}ltnis zwischen transmissaler Fr{\"u}hflussgeschwindigkeit und mitraler Anularebene (E/E') >14. 5, systolischer Pulmonalarteriendruck (sPAP) >38mmHg und absolute GLS<8\% wurden in den multivariablen Cox-Modellen als unabh{\"a}ngige echokardiographische Marker f{\"u}r ein schlechteres klinisches Ergebnis identifiziert.Auf der Grundlage dieser Marker wurde ein echokardiographischer Risikoscore (Echo Risk Score, von 0 bis 6 Punkten) erstellt, und die Patienten wurden in drei Risikogruppen eingeteilt: ein Score von 0 bis 1 als geringes Risiko, ein Score von 2 bis 3 als mittleres Risiko und ein Score von 4-6 als hohes Risiko. Nach Adjustierung f{\"u}r alle klinischen Kovariaten hatten Hochrisikopatienten im Vergleich zu Patienten mit niedrigem Risiko ein zwei- bis dreifach erh{\"o}htes Gesamtmortalit{\"a}tsrisiko (HR 2,42, 95\% CI 1,81-3,24), ein erh{\"o}htes Risiko f{\"u}r kardiovaskul{\"a}re Ereignisse (HR 2,75, 95\% CI 1,88-4,02) und ein erh{\"o}htes kombiniertes Risiko f{\"u}r kardiovaskul{\"a}re Ereignisse (HR 1,84, 95\% CI 1,43-2,36). Eine erh{\"o}hte Vorhersagekraft wurde nach Hinzuf{\"u}gung des Echo-Risiko-Scores entweder zu dem Modell mit klinischen Risikofaktoren oder zu dem Modell mit klinischen Risikofaktoren und N-terminalem Prohormon des natriuretischen Peptids des Gehirns festgestellt (alle P<0,001).

  abstract  = {Im Rahmen dieser Studie haben wir untersucht, ob die bei der diagnostischen Koronarangiographie gewählten Projektionen eine adäquate Darstellung der ostialen Gefäßabschnitte ermöglichen. Hierzu wurde im Rahmen einer retrospektiven Studie ein Patientenkollektiv von 54 Probanden eingeschlossen, bei denen sowohl ein Kardio-CT als auch eine diagnostische Herzkatheteruntersuchung durchgef{\"u}hrt worden war. Mithilfe des Kardio-CTs wurde die Line of Perpendicularity (LoP) der ostialen Koronargefäßabschnitte der LCA und der RCA ermittelt. Hieraus können die optimalen Angulationen f{\"u}r die angiographische Darstellung der ostialen Gefäßabschnitte abgeleitet werden. Im nächsten Schritt wurde {\"u}berpr{\"u}ft, ob die während der diagnostischen Koronarangiographie gewählten Projektionen auf dieser LoP (mit einer Divergenz von ± 10°) lagen. Zusätzlich haben wir untersucht, ob interventionell erfahrenen Kardiologen in der Lage sind, die Koronarangiographie im Hinblick auf die Qualit{\"a}t der Darstellung des Ostiums zu beurteilen. Ferner wurde verglichen, ob die in der Literatur empfohlenen Standardprojektionen eine optimale Darstellung der ostialen Segmente erlauben. Bei 81\% aller Patienten wurde der ostiumnahe Abschnitt der linken Koronararterie unverk{\"u}rzt dargestellt, wohingegen die Darstellung der rechten Koronararterie nur bei 44\% der Patienten ad{\"a}quat war. Der Vergleich der LoP zeigte, dass es große interindividuelle Unterschiede der Koronarostiumanatomie gibt. Daraus kann abgeleitet werden, dass mit sog. „Standardprojektionen" nur bei einem Teil der Patienten eine optimale und somit unverk{\"u}rzte Darstellung der ostialen Koronarsegmente m{\"o}glich wird. Bei einem beträchtlichen Anteil der Patienten muss man diese Projektionen variieren, um das Ostium bestmöglich darzustellen. Eine CT-basierte Bestimmung der Line of Perpendicularity kann dazu beitragen, die geeigneten Projektionen w{\"a}hrend einer Herzkatheteruntersuchung einzustellen und so die interindividuellen Verhältnisse der Koronaranatomie zu ber{\"u}cksichtigen.},

  abstract  = {In dieser klinisch retrospektiven Studie wurden 95 Patienten mit schwerer Aortenstenose und gleichzeitiger zumindest leicht- bis mittelgradiger Mitralklappeninsuffizienz vor und nach kathetergest{\"u}tztem AKE untersucht. Ziel war es, eine Verbesserung der MI nach TAVI zu detektieren und Pr{\"a}diktoren f{\"u}r eine m{\"o}gliche Verbesserung zu identifizieren, um solchen Patienten die individuell optimale Versorgung zu gew{\"a}hrleisten. Methoden: Zu Beginn der Studie wurde bei jedem Patienten eine umfangreiche echokardiographische Untersuchung durchgef{\"u}hrt, welche im Nachhinein manuell ausgewertet werden konnte. Dar{\"u}ber hinaus wurden allgemeine klinische Daten, wie beispielsweise Blutdr{\"u}cke und Vorerkrankungen erfasst, sowie eine routinem{\"a}ßige Blutentnahme durchgef{\"u}hrt. Nach TAVI wurde erneut eine echokardiographische Untersuchung vorgenommen, die sp{\"a}ter wiederum ausgewertet werden konnte. Ergebnisse: Alle Patienten wurden anhand der Ver{\"a}nderung der Mitralinsuffizienz nach TAVI in die Gruppen „keine Verbesserung" und „Verbesserung" unterteilt. Bei 71,6\% der Patienten konnte eine Verbesserung der MI nach TAVI verzeichnet werden, 32,6\% der Patienten zeigten sogar eine signifikante Verbesserung von mindestens zwei Schweregraden im Vergleich zur Baseline-Echokardiografie. Bei der Auswertung der echokardiografischen Daten konnte ein niedriger mittlerer transaortaler Druck (AV Pmean) als unabh{\"a}ngiger multivariater Pr{\"a}diktor identifiziert werden. Dar{\"u}ber hinaus konnte eine signifikant h{\"o}here {\"U}berlebensrate in der Patientengruppe „Verbesserung" der MI im Vergleich zur Gruppe „keine Verbesserung" nachgewiesen werden. Im Hinblick auf die 30-Tages-Mortalit{\"a}t unterschieden sich die beiden Gruppen nicht. Zusammenfassung: Patienten mit schwerer Aortenstenose leiden h{\"a}ufig auch an einer Mitralinsuffizienz. In dieser Studie konnte eine signifikante Verbesserung der MI nach TAVI nachgewiesen werden. Aus den erhobenen Daten l{\"a}sst sich schließen, dass eine ausf{\"u}hrliche echokardiographische Voruntersuchung mit genauer Mitbeurteilung der Mitralklappe bei TAVI-Patienten unerl{\"a}sslich ist und dass diese wichtige Erkenntnisse {\"u}ber den weiteren Verlauf einer gleichzeitig bestehenden MI liefern kann. So k{\"o}nnte ein alleiniger kathetergest{\"u}tzter Aortenklappenersatz bei sorgf{\"a}ltig ausgew{\"a}hlten Patienten eine vern{\"u}nftige Therapieoption bei Patienten mit kombinierter Aorten- und Mitralklappenerkrankung sein.},

  abstract  = {(1) Background: Metabolically healthy obesity (MHO) is a concept that applies to obese patients without any elements of metabolic syndrome (metS). In turn, metabolically unhealthy obesity (MUO) defines the presence of elements of metS in obese patients. The components of MUO can be divided into subgroups regarding the elements of inflammation, lipid and glucose metabolism and cardiovascular disease. MUO patients appear to be at greater risk of developing non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) compared to MHO patients. The aim of this study was to evaluate the influence of different MUO components on NAFLD and NASH in patients with morbid obesity undergoing bariatric surgery. (2) Methods: 141 patients undergoing bariatric surgery from September 2015 and October 2021 at RWTH Aachen university hospital (Germany) were included. Patients were evaluated pre-operatively for characteristics of metS and MUO (HbA1c, HOMA, CRP, BMI, fasting glucose, LDL, TG, HDL and the presence of arterial hypertension). Intraoperatively, a liver biopsy was taken from the left liver lobe and evaluated for the presence of NAFLD or NASH. In ordinal regression analyses, different factors were evaluated for their influence on NAFLD and NASH. (3) Results: Mean BMI of the patients was 52.3 kg/m\(^2\) (36-74.8, SD 8.4). Together, the parameters HbA1c, HOMA, CRP, BMI, fasting glucose, LDL, TG, HDL and the presence of arterial hypertension accounted for a significant amount of variance in the outcome, with a likelihood ratio of χ\(^2\) (9) = 41.547, p < 0.001, for predicting the presence of NASH. Only HOMA was an independent predictor of NASH (B = 0.102, SE = 0.0373, p = 0.007). Evaluation of steatosis showed a similar trend (likelihood ratio χ\(^2\) (9) = 40.272, p < 0.001). Independent predictors of steatosis were HbA1c (B = 0.833, SE = 0.343, p = 0.015) and HOMA (B = 0.136, SE = 0.039, p < 0.001). (4) Conclusions: The above-mentioned model, including components of MUO, was significant for diagnosing NASH in patients with morbid obesity undergoing bariatric surgery. Out of the different subitems, HOMA independently predicted the presence of NASH and steatosis, while HbA1c independently predicted steatosis and fibrosis. Taken together, the parameter of glucose metabolism appears to be more accurate for the prediction of NASH than the parameters of lipid metabolism, inflammation or the presence of cardiovascular disease.},
