Abstract
BACKGROUND Anxiety and limited patient comprehension may pose significant barriers when informing elderly patients about complex procedures such as transcatheter aortic valve implantation (TAVI). OBJECTIVES We aimed to evaluate the utility of medical graphics to improve the patient informed consent (IC) before TAVI. METHODS In this prospective, randomized dual center study, 301 patients were assigned to a patient brochure containing medical graphics (Comic group, n = 153) or sham information (Control group, n = 148) on top of usual IC. Primary outcomes were patient understanding of central IC-related aspects and periprocedural anxiety assessed by the validated Spielberger State Trait Anxiety Inventory (STAI), both analyzed by cognitive status according to the Montreal Cognitive Assessment (MoCA). RESULTS Patient understanding was significantly higher in the Comic group [mean number of correct answers 12.8 (SD 1.2) vs. 11.3 (1.8); mean difference 1.5 (95% CI 1.2-1.8); p < 0.001]. This effect was more pronounced in the presence of cognitive dysfunction (MoCA < 26) [12.6 (1.2) in the Comic vs. 10.9 (1.6) in the Control group; mean difference 1.8 (1.4-2.2), p < 0.001]. Mean STAI score declined by 5.7 (95% CI 5.1-6.3; p < 0.001) in the Comic and 0.8 points (0.2-1.4; p = 0.015) in the Control group. Finally, mean STAI score decreased in the Comic group by 4.7 (3.8-5.6) in cognitively impaired patients and by 6.6 (95% CI 5.8 to 7.5) in patients with normal cognitive function (p < 0.001 each). CONCLUSIONS Our results prove beneficial effects for using medical graphics to inform elderly patients about TAVI by improving patient understanding and reducing periprocedural anxiety (DRKS00021661; 23/Oct/2020). Medical graphics entailed significant beneficial effects on the primary endpoints, patient understanding and periprocedural anxiety, compared to the usual patient informed consent (IC) procedure. Patient understanding of IC-related aspects was significantly higher in the Comic group, with a more pronounced benefit in patients with cognitive impairment (p for IC method and cognitive status < 0.001, respectively; p for IC method x MoCA category interaction = 0.017). There further was a significant decline of periprocedural anxiety in patients with and without cognitive impairment (p for IC method x measuring time point < 0.001; p for IC method x MoCA category x measuring time point interaction = 0.018).

Abstract
Abstract
Conduction disturbances after transcatheter aortic valve replacement (TAVR) remain one of the most frequent complications.
The aim of this study was to analyze ECG changes after TAVR using contemporary valves and to detect risk factors for the need of further clinical evaluation according to new ESC pacing guidelines to evaluate pacemaker implantation.
In this retrospective analysis we included 850 patients (mean age 80±9 years, 51% female), who underwent TAVR in our institution from January 2019 until December 2020. A mean follow-up of 8.9±8.4 months and 217 (25.5%) patients was performed.
55% of the implanted valves were self-expandable, 45% balloon-expandable. After TAVR, 77 (9.1%) patients developed new LBBB and QRS >150ms, 26 (3.1%) new PR-time >240ms. Prolongation of PR-time and prolongation of QRS duration >20ms were seen in 20 (2.4%) and 90 (10.6%) patients with preexisting conduction disturbances. 152 (17.9%) patients needed pacemaker implantation post TAVR.
Developing a PR-prolongation of >20ms was associated with calcification of the annulus (OR 1.2 CI 95% 1.004–1.4; p=0.04). New LBBB (OR 0.45; CI 95% 0.25–0.79; p=0.006) and pacemaker implantation (OR 0.4; CI 95% 0.2–0.8; p=0.009) were correlated with the implantation of a self-expandable valve. Coronary heart disease (OR 3, CI 95% 1.07–8.2; p=0.04) and peripheral arterial disease (OR 2.6 CI 95% 1.18–5.6; p=0.02) were associated with prolongation of QRS >20ms. New LBBB with QRS >150ms was seen more often after post-dilatation (OR 1.03, CI 95% 1.01–1.05; p=0.05). Pre-existing AV block I° (OR 2.8, CI 95% 1.4–5.6; p<0.001), pre-existing RBBB (OR 20.5, CI 95% 7.5–56; p<0.001), nicotine abuse (OR 2, CI 95% 1.05–3.8; p=0.04), prosthesis oversizing (OR 1.06, CI 95% 1.006–1.11; p=0.03) and implantation depth (OR 1.13, CI 95% 1.006–1.26; p=0.04) were independent risk factors for pacemaker implantation.
During the follow-up 161 patients (18.9%) were hospitalized in 270 inpatient stays [cardiac decompensation (n=36, 13%), pacemaker implantation (n=9, 3.3%), acute coronary syndrome (n=12, 4.4%)]. 8 patients (80%) received a pacemaker implantation because of AV Block III° and 1 (10%) patient because of sick-sinus-syndrome (SSS). Analyzing the post TAVR ECG 5 (50%) had a new LBBB (3 (30%) with QRS >150ms) and 4 (40%) patients showed LBBB together with AV Block I°.
According to new guidelines 213 (25.1%) patients would have needed further clinical evaluation (EP study or ECG monitoring) after TAVR. AV-conduction abnormalities were associated with annulus calcification. Self-expandable valves were associated with new LBBB and pacemaker implantation. There seems to be a correlation between arteriosclerotic diseases and QRS width post TAVR. Pre-existing RBBB, AV block I°, implantation depth and prosthesis oversizing are important risk factors for pacemaker implantation post TAVR. New LBBB after TAVR is associated with a higher risk for pacemaker implantation in the long-term analysis.

Abstract
The monohydroxy alcohol 2-ethyl-1-hexanol mixed with the halogen-substituted alkyl halides 2-ethyl-1-hexyl chloride and 2-ethyl-1-hexyl bromide was studied using synchrotron-based x-ray scattering. In the diffraction patterns, an oxygen-related prepeak appears. The concentration dependence of its intensity, shape, and position indicates that the formation of the hydrogen-bonded associates of monohydroxy alcohols is largely hindered by the halogen alkane admixture. Using dielectric spectroscopy and high-resolution rheology on the same liquid mixtures, it is shown that these structural features are correlated with the relaxation mechanisms giving rise to supramolecular low-frequency dynamics.

Abstract
Polycrystalline dimethyl sulfone is studied using central-transition oxygen-17 exchange NMR. The quadrupolar and chemical shift tensors are determined by combining quantum chemical calculations with line shape analyses of rigid-lattice spectra measured for stationary and rotating samples at several external magnetic fields. Quantum chemical computations predict that the largest principal axes of the chemical shift anisotropy and electrical field gradient tensors enclose an angle of about 73°. This prediction is successfully tested by comparison with absorption spectra recorded at three different external magnetic fields. The experimental one-dimensional motionally narrowed spectra and the two-dimensional exchange spectrum are compatible with model calculations involving jumps of the molecules about their two-fold symmetry axis. This motion is additionally investigated by means of two-time stimulated-echo spectroscopy which allows for a determination of motional correlation functions over a wider temperature range than previously reported using carbon and deuteron NMR. On the basis of suitable second-order quadrupolar frequency distributions, sin-sin stimulated-echo amplitudes are calculated for a two-site model in the limit of vanishing evolution time and compared with experimental findings. The present study thus establishes oxygen-17 NMR as a powerful method that will be particularly useful for the study of solids and liquids devoid of nuclei governed by first-order anisotropies.

Abstract
The thiopentone sodium surge in plasma was investigated in 15 elderly surgical patients and 10 young adults during injection, over a period of 1 minute, of 4 mg of anaesthetic per kg of fat-free body weight (in 18 patients), and 5 mg per kg of fat-free body weight (7 patients). In keeping with prolonged circulation time in old age, thiopentone sodium reached the sampling site faster in the younger patients than it did in the older patients. In the majority of cases, thiopentone sodium concentrations in plasma reached a maximum of between 60 and 80 micrograms/ml. Mean thiopentone sodium concentrations in the older patients were 10% higher, but here values differed so widely that this result must be regarded as coincidental. It was, accordingly, impossible to establish any statistically verifiable differences between young and old patients by estimating the volume of thiopentone sodium distribution shortly after the end of injection. Plasma protein binding, 85% on average, with extremes ranging from 79% to 89% did not depend on thiopentone concentration or age. In the group of patients studied, it was not possible to confirm statistically that the plasma protein concentration influenced the rate of binding. Dosage according to fat-free body weight did not diminish inter-individual differences in plasma concentration-time profiles.
