- Abstract
Background: This new clinical practice guideline concerns the psychosocial diagnosis and treatment of patients before and after organ transplantation. Its objective is to establish standards and to issue evidence-based recommendations that will help to optimize decision making in psychosocial diagnosis and treatment. Methods: For each key question, the literature was systematically searched in at least two databases (Medline, Ovid, Cochrane Library, and CENTRAL). The end date of each search was between August 2018 and November 2019, depending on the question. The literature search was also updated to capture recent publications, by using a selective approach. Results: Lack of adherence to immunosuppressant drugs can be expected in 25-30% of patients and increases the odds of organ loss after kidney transplantation (odds ratio 7.1). Psychosocial interventions can significantly improve adherence. Metaanalyses have shown that adherence was achieved 10-20% more frequently in the intervention group than in the control group. 13-40% of patients suffer from depression after transplantation; mortality in this group is 65% higher. The guideline group therefore recommends that experts in psychosomatic medicine, psychiatry, and psychology (mental health professionals) should be involved in patient care throughout the transplantation process. Conclusion: The care of patients before and after organ transplantation should be multidisciplinary. Nonadherence rates and comorbid mental disorders are common and associated with poorer outcomes after transplantation. Interventions to improve adherence are effective, although the pertinent studies display marked heterogeneity and a high risk of bias. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Young adults who underwent liver transplantation in childhood (YALTs) are highly vulnerable to non-adherent behavior and psychosocial problems. During the COVID-19 pandemic, special efforts may be necessary to maintain contact with these patients and offer support. This can be achieved through the use of telemedicine. The study's objective was to assess adherence and the psychosocial situation of YALTs during the COVID-19 pandemic in Germany and to evaluate the utilization of video consultations., Methods: In May 2020, a questionnaire was sent to YALTs treated at the Hamburg University Transplant Center, accompanied by the offer of video appointments with the attending physician. The questionnaire included the Generalized Anxiety Disorder Scale 7, the Patient Health Questionnaire 2, and questions compiled by the authors., Results: Of 98 YALTs, 12% used the video consultation, while 65% had an in-person appointment. The 56 patients who completed the questionnaire did not report reduced medication adherence during the pandemic, but 40% missed follow-up visits with their primary care physician or check-up laboratory tests. About 70% of YALTs were afraid to visit their physician and the transplant center, and 34% were afraid of a SARS-CoV-2 infection. Mental health and well-being were unimpaired., Conclusions: During the COVID-19 pandemic, YALTs in our study did not show an increased need for psychosocial support, but a majority were afraid to attend medical appointments, and 40% reported lower appointment adherence. Acceptance of video consultations was lower than expected. The reasons for this need to be further investigated in order to optimize care., (© 2021 The Authors.

- Abstract
Understanding charge transport through molecular wires is important for nanoscale electronics and biochemistry. Our goal is to establish a simple first-principles protocol for predicting the charge transport mechanism in such wires, in particular the crossover from coherent tunneling for short wires to incoherent hopping for longer wires. This protocol is based on a combination of density functional theory with a polarizable continuum model introduced by Kaupp et al. for mixed-valence molecules, which we had previously found to work well for length-dependent charge delocalization in such systems. We combine this protocol with a new charge delocalization measure tailored for molecular wires, and we show that it can predict the tunneling-to-hopping transition length with a maximum error of one subunit in five sets of molecular wires studied experimentally in molecular junctions at room temperature. This suggests that the protocol is also well suited for estimating the extent of hopping sites as relevant, for example, for the intermediate tunneling-hopping regime in DNA.

7. Designing Long-Range Charge Delocalization from First-Principles.

- Abstract
Efficient electronic communication over long distances is a desirable property of molecular wires. Charge delocalization in mixed-valence (MV) compounds where two redox centers are linked by a molecular bridge is a particularly well-controlled instance of such electronic communication, thus lending itself to comparisons between theory and experiment. We study how to achieve and control long-range charge delocalization in cationic organic MV systems by means of Kohn-Sham density functional theory (DFT) and show that a captodative substitution approach recently suggested for molecular conductance ( Stuyver et al. J. Phys. Chem. C 2018 , 122 , 3194 ) greatly enhances charge delocalization in p-phenylene-based wires. To ensure the adequacy of our DFT methods, we validate different protocols for organic MV systems of different lengths. The BLYP35 hybrid functional combined with a polarizable continuum model, established by Renz and Kaupp, is indeed capable of correctly describing experimentally observed length-dependent charge delocalization, in contrast to the long-range corrected functionals ω-B97X-D and ω-PBE. We also discuss the implications of these results for a first-principles description of the transition between coherent tunneling and incoherent hopping regimes in molecular conductance.

- Abstract
For the last few years, the German Medical Association's guidelines for transplant medicine have been subject to an extensive revision process. The present contribution presents recommendations regarding the psychosocial evaluation of patients prior to organ transplantation, which were developed by experts from the Psychology/Psychosomatics committee of the German Transplant Society with the aim to incorporate the recommendations into the guidelines. The main objective is to establish a mandatory psychosocial evaluation for all patients prior to their admission to the transplant waiting list. Contents, potential contraindications, and the procedure of the evaluation are described. Furthermore, the qualification deemed necessary for the examiners is addressed in detail. Finally, the future need for action is determined., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

- Abstract
Transplant medicine in Germany is regulated by mandatory guidelines of the German Medical Association, the transplant law passed in 1997 serving as the legal basis. In 2012 a comprehensive modification of the guideline procedure was initiated. Since then, all guidelines are subject to an elaborate revision process. The present contribution initially depicts relevant background information and explains the formal aspects of the guideline procedure. Subsequently, the psychologically/psychosomatically relevant contents of the guidelines for organ transplantation are presented. With regard to this matter, first of all the state of the guidelines prior to the current revisions is described. Afterwards, already adopted revisions as well as published drafts are explicated, followed by the authors' evaluation of the revisions and recommendations for further revisions to be pursued. In addition, recommendations on psychosocial aspects regarding the evaluation and follow-up in living organ donation are presented, which have been submitted in similar form to the German Medical Association for a currently drawn up guideline., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

- Abstract
Aim Since there is no consensus about how to perform the predonation psychosocial evaluation of living kidney donor candidates, this is conducted differently in German transplant centers. Thus, the goal of the study was to learn more about how psychosocial evaluations are currently conducted in German transplant centers. Methods The psychosocial evaluators of the 38 transplant centers performing kidney transplantations in 2015 were contacted and asked to participate in an anonymous online survey. Results Psychosocial evaluators from 28 (75%) transplant centers responded. In only 30 (4%) of the evaluations contraindications for donation were reported. In most centers the psychosocial evaluation was performed after the completion of all medical tests. The evaluations were realized after only short waiting periods and were reported to be time-consuming. Financial reimbursement was mainly realized by internal cost allocation. In most centers the evaluators used semi-structured interviews. Still, there was limited consensus about structure and content of the psychosocial evaluation. Conclusion Standardization of the psychosocial evaluation process could be helpful to enable comparisons between transplant centers and to achieve equal opportunities for the potential living kidney donors and recipients., Competing Interests: Interessenkonflikt: Die Autoren geben an, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

- Abstract
Background: Due to the shortage of cadaveric organs, living kidney donation has begun to serve as the most crucial organ pool. Transplant centers have a legitimate interest in expanding the pool of donors. A psychosocial evaluation is established in transplantation centers to prevent donors from possible emotional harm in the aftermath of donation. We explored if the resilience questionnaire is an appropriate measure of the mental stability. To standardize procedures of psychosocial evaluation and to optimize donor recruitment, we present our evaluation protocol and analyze the causes of exclusion from donation., Method: In a naturalistic design, we compared resilience and quality of life in eligible and excluded donors at the time point of donation. Potential living kidney donors (N = 161) participated in the obligatory psychosomatic evaluation. Quality of life (World Health Organization Quality of Life, WHOQOL-Bref) and resilience (Resilience Scale, RS-12) were measured. Three months after nephrectomy donors quality of life was screened in a follow-up., Results: In the evaluation interview donors were classified as eligible (n = 142) or excluded (n = 12). Nonrelated donors (n = 3) were excluded from donation significantly more often (p < .011). Eligible donors (M = 78.42, SD = 10.19) had higher values for resilience than excluded donors (M = 72.7, SD = 8.18, p < .04), who showed values comparable to the norm. In all domains of quality of life, eligible donors had significantly higher values than healthy normals (p < .001). After donation health-related quality of life decreased, but was comparable to the norm. A regression analysis showed that resilience was a significant predictor for all dimensions of quality of life before donation (R(2) = 10.2-24.6 %). Post-donation quality of life was significantly correlated with pre-donation resilience scores (p < .05)., Conclusions: The resilience score predicts high mental quality of life before and after donation. Therefor it can be implemented as a self-rating instrument to further objectify donor's mental stability. Despite the stressful life event of donation, donor candidates presented high resilience and high levels of quality of life. Therefor our findings support health care providers` intentions to improve living donation. In the group of excluded donors nonrelated persons were overrepresented. Guidelines for the admission of nonrelated donors are currently unclear and need to be optimized.
