Background
Cardiovascular magnetic resonance (CMR) imaging is considered the reference methodology for cardiac morphology and function but requires manual post-processing. Whether novel artificial intelligence (AI) -based automated analyses deliver similar information for risk stratification is unknown. Therefore, this study aimed to investigate feasibility and prognostic implications of AI-based analyses.
Methods
CMR data (n = 1017 patients) from two myocardial infarction multi-center trials were included. Analyses of biventricular parameters including ejection fraction (EF) were manually and automatically assessed using conventional and AI-based software. Obtained parameters entered regression analyses for prediction of major adverse clinical events (MACE) defined as death, reinfarction or congestive heart failure within one-year after the acute event.
Results
Both manual and uncorrected automated volumetric assessments showed similar impact on outcome on univariate (LVEF HR 0.93, [95% CI 0.91-0.95]; p < 0.001 for manual and HR 0.94 [0.92-0.96]; p < 0.001 for automated) and multivariable analyses (LVEF HR 0.95, [0.92-0.98]; p = 0.001 for manual and HR 0.95 [CI 0.92-0.98]; p = 0.001 for automated). Manual correction of the automated contours did not lead to improved risk prediction (LVEF AUC 0.67 automated vs. 0.68 automated corrected, p = 0.49). There was acceptable agreement (bias: 2.6%, 95% limits of agreement [LOA] -9.1-14.2%, intraclass correlation coefficient [ICC] 0.88 [0.77-0.93] for LVEF) of manual and automated volumetric assessments.
Conclusions
User independent volumetric analyses performed by fully automated software are feasible and results are equally predictive of MACE compared with conventional analyses in patients following myocardial infarction.

Abstract
Abstract
Background
Peripheral artery disease (PAD) is a major manifestation of atherosclerosis and a risk factor for morbidity and mortality. PAD itself is associated with increased arterial stiffness with impact on cardiac functions. Previous studies have demonstrated that augmentation index (AIx) and central blood pressure (CBP) correlate with increased cardiovascular mortality. This mechanism has been described as arterio-ventricular (AV) coupling with altered ventricular afterload and a depressed ventricular function, measured by global longitudinal strain (GLS). The impact of PAD-related endovascular treatment on arterial stiffness, central hemodynamics and potential impact on AV coupling has not been elucidated until now.
Purpose
Aim of the study was to investigate, if endovascular treatment of PAD improves cardiac function via enhanced central hemodynamics and AV coupling.
Methods
To this aim 77 patients with known symptomatic PAD who underwent interventions in the iliac and femoropopliteal arteries were included in a cross-sectional study. AIx, CBP and GLS were determined using dedicated waveform analysis and echocardiography before and after endovascular treatment.
Results
Mean age was 65.1±10.4 years with 66.2% male patients. Symptoms were classified by Fontaine classification (stage IIb 80.7%, stage III 5.8% and stage IV 13.5%). Iliac vessel intervention was performed in 16 and femoropopliteal intervention in 61 cases. A stentless approach was feasible in 55 patients with DCB treatment and atherectomy.
After endovascular treatment, peripheral perfusion was enhanced (ABI 0.45±0.6 vs 0.81±0.5, p<0.0001). Moreover, central hemodynamics were improved (AIX 33.7±3% vs 27.9±2%, p=0.0008; AP 17.8±2 mmHg vs 14.0±2 mmHg, p=0.0004; central PP 52.4±6 mmHg vs 46.4±6 mmHg, p=0.0001). Impressively, left ventricular function was also significantly improved (GLS −15.7±2.3% vs −17.1±2.8%, p=0.005) with an improvement in AV coupling (PWV/GLS ratio −0.58m/sec% vs −0.56m/sec%, p<0.01).
Conclusion
Our results demonstrate that endovascular treatment of the peripheral vessels is associated with an improvement of central hemodynamics and left ventricular function via enhanced AV coupling. These prognostic relevant markers of cardiovascular disease could point to an overall potential mortality benefit through PAD treatment. Further investigation of the underlying mechanisms of AV coupling in the setting of endovascular treatment of PAD with impact on cardiovascular mortality is needed in this high-risk population.

Abstract
Abstract
Background
Cardiovascular diseases are the leading causes of death in the industrialized world. In addition to coronary heart disease, PAD defines morbidity and is associated with increased mortality. Guideline-recommended therapy and specialized ambulatory care is essential for optimal treatment. Knowledge of the treatment structures, contact with dedicated specialists and pharmacotherapy in the outpatient area are essential for improving treatment, reducing symptoms and finally improve mortality in this high-risk population.
Methods
The study is based on the ambulatory claims data of the panel doctors services according to § 295 SGB V and drug prescription data according to § 300 SGB V. The prevalence of PAD in Germany (medical diagnoses of PAD ICD I70.2–9) was analyzed by age and gender-specific characteristics with a timeframe of 10 years (2009–2018). In addition, the current ambulatory care structure was examined subdivided by vascular specialist (vascular surgeons or angiologists) and primary care physicians (internal medicine or general practitioners). Additionally, the prescription of guideline-recommended pharmacotherapy like statins and antiplatelet inhibitors was analyzed for the years 2009–2016.
Results
An increase of PAD diagnosis was observed with a maximum in 2018 with 2.280.000 patients in Germany. The rise of PAD patients strongly correlates with increased age (age group 50–59: 243.000, age group 60–69: 533.000, age group 70–79: 735.000, age group 75–79: 438.000, age group 80–89: 710.000) and more commonly affects males (55%) than females (45%). Access to vascular specialist was low for all age groups with only 11% of patients receiving care from vascular surgeons and only 9% from angiologists. However, 99% received care by a primary care physician.
The prescription of lipid-lowering drugs and platelet aggregation inhibitors in the current analysis period from 2009–2016 is insufficient, with only 46% receiving statins and 29% receiving antiplatelets and 15% oral anticoagulation,
Conclusion
There are relevant differences in age and gender-specific prevalence of PAD in Germany. In addition to the regular care provided by primary care physicians, PAD patients are in need for specialized vascular care. Guideline recommended prescriptions are alarmingly low in PAD patients. There is a clear need to improve the treatment algorithms in the high-risk PAD population.

Abstract
Abstract
Background and aims
Aortic stiffness is an independent predictor of cardiovascular morbidity and mortality and thus simple, rapid and preferably automated techniques are indispensableto persue a global approach in risk statification. A novel oscillometric based carotido-femoral pulse-wave velocity (cfPWV) was investigated, regarding diagnostic accuracy, sensitivity and specificity and with emphasis on costs, training curves and procedural time effort.
Methods
In a single-center crossover study, we evaluated subjects free of known cardiovascular disease (CVD) and CVD subjects and a subgroup with peripheral artery disease (PAD) undergoing ankle-brachial index (ABI) and PWV measurements using oscillometry (BoSo, Bosch + Sohn, Germany) compared to tonometry (SphymoCor, Atcor Australia). Pearson's correlation analysis was used to assess the relationship of PWV measurements for both methods. Moreover, examination times and costs were compared.
Results
A total of 174 study subjects underwent assessment of oscillometric and tonometric PWV measurements. CVD-free subjects (n=57) were younger (60.4±15.6 vs. 67±12.9 years, p=0.003) compared to CVD subjects (n=117). PWV measurements showed significant correlations in CVD-free subjects (r=0.797, p<0.001), in CVD subjects (r=0.817, p<0.001) and the subgroup of PAD subjects (r=0.807, p<0.001). Sensitivity, specificity, positive predictive value and negative predictive value of the oscillometric measurement for detecting arterial stiffness reached 93%, 84%, 86%, and 92%. The examination time of the oscillometric method was shorter compared to tonometry (4.4±0.5 vs. 9.2±0.8 min, p<0.001) in line with reduced costs.
Conclusion
Using a simple and rapid automated oscillometric method, we provide good diagnostic accuracy for the determination of aortic stiffness through PWV, both in CVD-free and in CVD subjects. This might help in terms of cost-effectiveness and simplification in daily practice to screen for cardiovascular morbidity and for vascular damage in atherosclerosis.

Abstract
Abstract
Background
Cardiovascular magnetic resonance (CMR) represents the clinical gold standard for the assessment of biventricular morphology and function. Since manual post-processing is time-consuming and prone to observer variability, efforts have been directed towards automated volumetric quantification. In this study, we sought to validate the accuracy of a novel approach providing fully automated quantification of biventricular volumes and function in a “real-world” clinical setting.
Methods
Three-hundred CMR examinations were randomly selected from the local data base. Fully automatic quantification of left ventricular (LV) mass, LV and right ventricular (RV) end-diastolic and systolic volumes (EDV/ESV), stroke volume (SV) and ejection fraction (EF) were performed overnight using commercially available software. Parameters were compared to manual assessments. Sub-group analyses were further performed according to image quality, scanner field strength, the presence of implanted aortic valves and repaired Tetralogy of Fallot (ToF).
Results
Biventricular automatic segmentation was feasible in all 300 cases. Overall agreement between fully automated and manually derived LV parameters was good (LV-EF: intra-class correlation coefficient [ICC] 0.95; bias −2.5% [SD 5.9%]), whilst RV agreement was lower (RV-EF: ICC 0.72; bias 5.8% [SD 9.6%]). Lowest agreement was observed in case of severely altered anatomy, e.g. marked RV dilation but normal LV dimensions in repaired ToF (LV parameters ICC 0.73–0.91; RV parameters ICC 0.41–0.94) and/or reduced image quality (LV parameters ICC 0.86–0.95; RV parameters ICC 0.56–0.91), which was more common on 3.0T than on 1.5T.
Conclusions
Fully automated assessment of biventricular morphology and function is robust and accurate in a clinical routine setting with good image quality and can be performed without any user interaction. However, in case of demanding anatomy (e.g. repaired ToF, severe LV hypertrophy) or reduced image quality, quality check and manual re-contouring is still required.

Abstract
Background Radial artery access is the primary approach for coronary interventions due to higher safety profile in comparison to femoral access. Radial artery occlusion (RAO) is the main complication of transradial catheterization that can lead to severe symptoms and a permanent artery occlusion. The incidence of RAO after transradial access ranges from 5 to 38% and data regarding treatment is scarce. Whether anticoagulation and vasoactive medication provides an additional benefit in recovery of radial artery patency (RAP) after catheterization has not been investigated in detail. Aim The objective was to investigate the impact of anticoagulation and vasoactive medication on regained patency after documented RAO following transradial catheterization. Patients and methods Overall 2635 patients were screened. 2215 (84%) catheterizations were performed by femoral and 420 (16%) by radial access. In 30 patients RAO was observed. In case of RAO patients were classified in three groups: Anticoagulation, anticoagulation added with alprostadil and controls. Follow-up was conducted after 3 months with ultrasound and clinical examination. Results Eight patients received anticoagulation and 11 patients anticoagulation together with alprostadil. Eleven patients served as controls. Recovery of RAP after catheterization was higher following either treatment (79.5%) compared to controls (0%, p = 0.006). Subgroup analysis yielded a higher RAP recovery in patients treated with anticoagulation (62.5%) as compared to controls (0%, p = 0.002). No effect on regained RAP was found with additional alprostadil therapy (33.3%) compared to anticoagulation therapy (62.5%, p = 0.229). Conclusion RAO should be treated with anticoagulation to regain patency. Addition of vasoactive medication does not lead to further beneficial effects. Further research is needed regarding preventive and therapeutic strategies following RAO.

Abstract
Due to the spread of intervertebral disc degeneration, insurance companies and experts are regularly confronted with related assessments of insured persons under their private accident insurance. These claims pose a particular challenge for experts, since, in addition to the clinical assessment of the facts, extensive knowledge of general accident insurance conditions, case law and current study findings is required. Each case can only be properly assessed through simultaneous consideration of both the medical and legal facts. These guidelines serve as the basis for experts and claims.managers with respect to the appropriate individual factual assessment of intervertebral disc degeneration in private accident insurance.

Abstract
Aim To assess intervendor agreement of cardiovascular magnetic resonance feature tracking (CMR-FT) and to study the impact of repeated measures on reproducibility. Materials and methods Ten healthy volunteers underwent cine imaging in short-axis orientation at rest and with dobutamine stimulation (10 and 20 μg/kg/min). All images were analysed three times using two types of software (TomTec, Unterschleissheim, Germany and Circle, cvi42, Calgary, Canada) to assess global left ventricular circumferential (Ecc) and radial (Err) strains and torsion. Differences in intra- and interobserver variability within and between software types were assessed based on single and averaged measurements (two and three repetitions with subsequent averaging of results, respectively) as determined by Bland–Altman analysis, intraclass correlation coefficients (ICC), and coefficient of variation (CoV). Results Myocardial strains and torsion significantly increased on dobutamine stimulation with both types of software (p<0.05). Resting Ecc and torsion as well as Ecc values during dobutamine stimulation were lower measured with Circle (p<0.05). Intra- and interobserver variability between software types was lowest for Ecc (ICC 0.81 [0.63–0.91], 0.87 [0.72–0.94] and CoV 12.47% and 14.3%, respectively) irrespective of the number of analysis repetitions. Err and torsion showed higher variability that markedly improved for torsion with repeated analyses and to a lesser extent for Err. On an intravendor level TomTec showed better reproducibility for Ecc and torsion and Circle for Err. Conclusions CMR-FT strain and torsion measurements are subject to considerable intervendor variability, which can be reduced using three analysis repetitions. For both vendors, Ecc qualifies as the most robust parameter with the best agreement, albeit lower Ecc values obtained using Circle, and warrants further investigation of incremental clinical merit. This is the first comparison of two types of CMR-FT software resulting in clinically valuable inter-vendor agreement data. Assessment of myocardial strain and torsion is feasible with both types of software at rest and with dobutamine stimulation. For both vendors, Ecc qualifies as the most robust parameter with the lowest variability.

Abstract
We present measurements of radio emission from cosmic ray air showers that took place during thunderstorms. The intensity and polarization patterns of these air showers are radically different from those measured during fair-weather conditions. With the use of a simple two-layer model for the atmospheric electric field, these patterns can be well reproduced by state-of-the-art simulation codes. This in turn provides a novel way to study atmospheric electric fields.

Abstract
AIM To evaluate the potential of real-time phase-contrast flow magnetic resonance imaging (MRI) at 40 ms resolution for the simultaneous determination of blood flow in the ascending aorta (AA) and superior vena cava (SVC) in response to reduced intrathoracic pressure (Mueller manoeuvre). MATERIALS AND METHODS Through-plane flow was assessed in 20 healthy young subjects using real-time phase-contrast MRI based on highly undersampled radial fast low-angle shot (FLASH) with image reconstruction by regularized non-linear inversion. Haemodynamic alterations (three repetitions per subject = 60 events) were evaluated during normal breathing (10 s), inhalation with nearly closed epiglottis (10 s), and recovery (20 s). RESULTS Relative to normal breathing and despite interindividual differences, reduced intrathoracic pressure by at least 30 mmHg significantly decreased the initial peak mean velocity (averaged across the lumen) in the AA by -24 ± 9% and increased the velocity in the SVC by +28 ± 25% (p < 0.0001, n = 23 successful events). Respective changes in flow volume per heartbeat were -25 ± 9% in the AA and +49 ± 44% in the SVC (p < 0.0001, n = 23). Flow parameters returned to baseline during sustained pressure reduction, while the heart rate was elevated by 10% (p < 0.0001) after the start (n = 24) and end (n = 17) of the manoeuvre. CONCLUSIONS Real-time flow MRI during low intrathoracic pressure non-invasively revealed quantitative haemodynamic adjustments in both the AA and SVC.

Abstract
"Communicative psychotherapy" was developed in the 1960s by the East German psychotherapist and psychiatrist Christa Kohler (1928-2004) for the treatment of "neuroses". Similar to established present-day psychotherapeutic methods, such as cognitive behaviour therapy, it combined diverse therapeutic approaches into an integrated treatment programme. This included individual and group therapy, exercise, work and occupational therapy. In contrast to modern psychotherapeutic practice, communicative psychotherapy was based on a firm system of values, namely socialist ideals. According to this system, psychological breakdown was viewed and treated ideologically. In addition, any lack of conformity with the East German system was likewise regarded as a psychopathological deviation, which should be subjected to psychological treatment. The latter concept requires a critical analysis from a current-day perspective. For the first time, this paper concentrates on Kohler's work on neuroses and the theory and practice of her communicative psychotherapy, albeit without neglecting Kohler's other scientific works, her biographical information and her Stasi documents.
