Abstract
Hintergrund: Über das Risiko einer Virusinfektion mit dem schweren akuten Atemwegssyndrom Coronavirus 2 (SARS-CoV-2) bei Krebspatienten, von denen viele immungeschwächt und damit anfälliger für eine Vielzahl von Infektionen sind, ist sehr wenig bekannt. Als Vorsichtsmaßnahme haben viele klinische Studien während der ersten Welle der weltweiten Pandemie des neuartigen Coronavirus (COVID-19) die Aufnahme von Patienten pausiert. In diesem Fallbericht beschreiben wir die erfolgreiche Behandlung eines Patienten mit rezidiviertem und refraktärem Multiplem Myelom (MM), der unmittelbar nach der klinischen Genesung von COVID-19 mit einer chimären Antigenrezeptor (CAR)-T-Zelltherapie mit Anti-B-Zellreifungsantigen (BCMA) behandelt wurde. Fallvorstellung: Der 57-jährige weiße männliche Patient war seit 4 Jahren an MM erkrankt und galt bei der Vorstellung zur CAR-T-Zelltherapie als pentarefraktär. Er hatte eine Immunsuppression in seiner medizinischen Vorgeschichte und er erhielt am Tag vor der COVID-19-Diagnose eine Dosis lymphdepletierender Chemotherapie (LDC). Dieser Patient konnte eine erhebliche Immunantwort gegen das SARS-CoV-2-Virus aufbauen, und antivirale Antikörper bleiben auch 2 Monate nach Erhalt einer Anti-BCMA-CAR-T-Zelltherapie noch nachweisbar. Die kürzliche SARS-CoV-2-Infektion bei diesem Patienten führte nicht zu einer Exazerbation des CAR-T-assoziierten Zytokin-Freisetzungssyndroms (CRS) und umgekehrt führte die CAR-T-Zelltherapie nicht zu Komplikationen im Zusammenhang mit COVID-19. Einen Monat nach der CAR-T-Zell-Infusion wurde bei dem Patienten ein unbestätigtes partielles Ansprechen nach den Kriterien der International Myeloma Working Group (IMWG) festgestellt. Schlussfolgerung: Unser Fall liefert einen wichtigen Kontext für die Wahl der Behandlung von MM-Patienten in Zeiten von COVID-19 sowie für die Frage, ob die CAR-T-Therapie auch bei Patienten verabreicht werden kann, die von COVID-19 genesen sind. Da die COVID-19-Pandemie weltweit anhält, ist eine umfangreiche Diskussion über die Entscheidung, ob mit der CAR-T-Zelltherapie fortgefahren werden soll, erforderlich, wobei die potenziellen Risiken und Vorteile der Therapie gegeneinander abgewogen werden müssen. Dieser Fall legt nahe, dass es möglich ist, die Anti-BCMA-CAR-T-Zelltherapie nach der Genesung von COVID-19 erfolgreich abzuschließen. Die Studie CRB-402 wurde am 6. September 2017 bei clinicaltrials.gov registriert (NCT03274219).

Abstract
BACKGROUND Very little is known about the risk that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral infection poses to cancer patients, many of whom are immune compromised causing them to be more susceptible to a host of infections. As a precautionary measure, many clinical studies halted enrollment during the initial surge of the global Novel Coronavirus Disease (COVID-19) pandemic. In this case report, we detail the successful treatment of a relapsed and refractory multiple myeloma (MM) patient treated with an anti-B cell maturation antigen (BCMA) chimeric antigen receptor (CAR) T cell therapy immediately following clinical recovery from COVID-19. CASE PRESENTATION The 57 year old Caucasian male patient had a 4-year history of MM and was considered penta-refractory upon presentation for CAR T cell therapy. He had a history of immunosuppression and received one dose of lymphodepleting chemotherapy (LDC) the day prior to COVID-19 diagnosis; this patient was able to mount a substantial immune response against the SARS-CoV-2 virus, and antiviral antibodies remain detectable 2 months after receiving anti-BCMA CAR T cell therapy. The recent SARS-CoV-2 infection in this patient did not exacerbate CAR T-associated cytokine release syndrome (CRS) and conversely the CAR T cell therapy did not result in COVID-19-related complications. One month after CAR T cell infusion, the patient was assessed to have an unconfirmed partial response per International Myeloma Working Group (IMWG) criteria. CONCLUSION Our case adds important context around treatment choice for MM patients in the era of COVID-19 and whether CAR T therapy can be administered to patients who have recovered from COVID-19. As the COVID-19 global pandemic continues, the decision of whether to proceed with CAR T cell therapy will require extensive discussion weighing the potential risks and benefits of therapy. This case suggests that it is possible to successfully complete anti-BCMA CAR T cell therapy after recovery from COVID-19. CRB-402 study registered 6 September 2017 at clinicaltrials.gov (NCT03274219).

Abstract
In adults, trauma imagery has proven to be a useful tool to assess the neural mechanisms of psychological trauma processing. In adolescents, heterogeneous results could be found for other tasks, however, a trauma imagery paradigm has not been evaluated. For this purpose, we investigated a trauma imagery paradigm with control scripts to assess neural correlates of traumatic experiences in youth. 15 adolescents, who had experienced a traumatic interpersonal event in the past and have developed clinically relevant symptoms, underwent an fMRI scan while listening to their individual trauma- versus two control scripts (positive/negative). We analysed a parametric contrast of the imagery phases (trauma > negative > positive) which revealed activity in the thalamus, dorsal anterior cingulate cortex, cuneus, dorsomedial prefrontal cortex and amygdala. Additionally, amygdala-activity correlated positively with depression-symptom-severity. Our data provide evidence for the feasibility of fMRI during a trauma imagery task in adolescents to investigate networks previously related to hyperarousal in adults with PTSD. Further, we demonstrate the specificity of the activated networks for trauma imagery as compared to imagery of other emotional situations. The task might be particularly useful to evaluate neural correlates of treatment in adolescents when hyperarousal is a target symptom.

Abstract
Recent advancements in bioanalytical techniques have led to the development of novel and robust diagnostic approaches that hold promise for providing optimal patient treatment, guiding prevention programs and widening the scope of personalized medicine. However, these advanced diagnostic techniques are still complex, expensive and limited to centralized healthcare facilities or research laboratories. This significantly hinders the use of evidence-based diagnostics for resource-limited settings and the primary care, thus creating a gap between healthcare providers and patients, leaving these populations without access to precision and quality medicine. Smartphone-based imaging and sensing platforms are emerging as promising alternatives for bridging this gap and decentralizing diagnostic tests offering practical features such as portability, cost-effectiveness and connectivity. Moreover, towards simplifying and automating bioanalytical techniques, biosensors and lab-on-a-chip technologies have become essential to interface and integrate these assays, bringing together the high precision and sensitivity of diagnostic techniques with the connectivity and computational power of smartphones. Here, we provide an overview of the emerging field of clinical smartphone diagnostics and its contributing technologies, as well as their wide range of areas of application, which span from haematology to digital pathology and rapid infectious disease diagnostics.

Abstract
Inhibition of DYRK1A kinase, produced by chromosome 21 and consequently overproduced in trisomy 21 subjects, has been suggested as a therapeutic approach to treating the cognitive deficiencies observed in Down syndrome (DS). We now report the synthesis and potent DYRK1A inhibitory activities of fluoro derivatives of 3,5-di(polyhydroxyaryl)-7-azaindoles (F-DANDYs). One of these compounds (3-(4-fluorophenyl)-5-(3,4-dihydroxyphenyl)-1H-pyrrolo[2,3-b]pyridine, 5a) was selected for in vivo studies of cognitive rescuing effects in a standard mouse model of DS (Ts65Dn line). Using the Morris water maze task, Ts65Dn mice treated i.p. with 20 mg/kg of 5a performed significantly better than Ts65Dn mice treated with placebo, confirming the promnesiant effect of 5a in the trisomic mice. Overall, these results demonstrate for the first time that selective and competitive inhibition of DYRK1A kinase by the F-DANDY derivative 5a may provide a viable treatment strategy for combating the memory and learning deficiencies encountered in DS.

Abstract
In this case report, we describe the case of a 30-year-old obese patient with severe acute pancreatitis complicated during hospitalization by the development of infected necrosis, a pseudocyst and an abscess. We demonstrate a possible solution to these complications using a combination of minimally invasive approaches. The contribution of this case report resides in that it presents a combination of the percutaneous approach and the endosonographic approach in the treatment of pancreatic necrosis. We believe that in such an extensive necrosis of the pancreas as is described in our case, this combined approach is optimal. The condition for implementing such a procedure is a well-staffed and technically equipped workplace.

Abstract
Objective In patients with multiple myeloma, bendamustine monotherapy is effective as 1st and 2nd line therapy. However, data for patients with advanced multiple myeloma is rare. Methods In this retrospective analysis we have identified 39 patients with relapsed or refractory multiple myeloma by means of case research, who have been treated at our institution with bendamustine as salvage therapy. After in median 2 lines of prior therapy (range:1-5) patients received in median 3 (range: 1-10) cycles of bendamustine. Bendamustine dosage was 80-150 mg on day 1+2 of a monthly cycle. Bendamustine was administered as monotherapy in 39% of patients, whereas 61% received concomitant steroids. Results Toxicity was mild to moderate. Response rates were as follows: 3% vgPR, 33% PR, 18% MR, 26% SD and 20% PD. The median event-free and overall survival were 7 and 17 months, respectively. Conclusions In conclusion, in patients with advanced multiple myeloma bendamustine is effective and associated with mild toxicity. Therefore, the role of bendamustine in patients with multiple myeloma should be investigated in further clinical trials.

Abstract
BACKGROUND AND STUDY AIMS To compare the rate of detection of colorectal neoplastic lesions using the selective photosensitizer precursor hexaminolevulinate (HAL) combined with a new fluorescence video endoscope system against that of standard white light endoscopy, and secondarily, to evaluate the safety profile of HAL-induced fluorescence colonoscopy. PATIENTS AND METHODS This prospective phase II clinical pilot study from two hospital study centers included 25 patients with known or highly suspected colorectal neoplasia. They underwent sensitization with locally applied 500 ml HAL enemas at a concentration of 1.6 mmol/L. At 60 minutes after enteral HAL administration, fluorescence imaging was done using a special light source capable of delivering either white light or blue excitation light. Red fluorescence induced by illumination with blue light was detected via a prototype fluorescence video colonoscope. Biopsies were taken from suspicious areas found with white or blue light. RESULTS Using histology as the gold standard, 55 / 93 of neoplastic lesions were detected with white light endoscopy, 53 / 93 with both white and blue light, 38 / 93 with blue light and second-pass white light, and 27/93 with blue light only. Of all neoplastic lesions, 91 / 93 revealed red fluorescence under fluorescence imaging ( P < 0.0001). Fluorescence mode showed 38.7 % (36 / 93) more neoplasms than did white light endoscopy. An isolated slight elevation of bilirubin, by a factor of 1.5, was noted after the administration of HAL. CONCLUSIONS Administration of HAL as enema induces selective lesion fluorescence and increases lesion detection rate in patients with colorectal neoplasia, especially of flat, nonvisible adenomas.

Abstract
BACKGROUND This randomized, double-blinded volunteer study was designed to evaluate the ED(99) volume of local anaesthetic for sciatic nerve blocks using a step-up/step-down methodology. METHODS A maximum of 20 volunteers were included to receive an ultrasound-guided sciatic nerve block with mepivacaine 1.5% and a starting volume of 0.2 ml mm(-2) cross-sectional nerve area. In cases of a complete sensory block, the volume was reduced by 0.02 ml mm(-2) cross-sectional nerve area until the first block failed. Thereafter, the volume of local anaesthetic was increased by 0.02 ml mm(-2) cross-sectional nerve area. After three cycles of successful/failed blocks, the ED(99) volume of local anaesthetic could be calculated by a probability function. The influence of the volumes of local anaesthetics on sensory onset times and duration of sensory block was evaluated by linear regression. RESULTS The ED(99) volume of local anaesthetic for sciatic nerve block was calculated with 0.10 ml mm(-2) cross-sectional nerve area. The correlation between the volume of local anaesthetic and the sensory onset time was weak (r=0.14), whereas the correlation between the volume of local anaesthetic and the duration of sensory block was moderate (r=0.65). CONCLUSIONS This is the first study where an ED(99) volume of local anaesthetic for sciatic nerve block has been evaluated. The resulting local anaesthetic volume of 0.10 ml mm(-2) cross-sectional nerve area seems to have no impact on sensory onset time, whereas the duration of sensory block is shorter.

Abstract
Cyproterone acetate (CPA) has been discovered more than 25 years ago and it was the first antiandrogen suitable for clinical use. CPA inhibits the action of endogenous and exogenous androgens at all androgen target organs; these include the prostate, seminal vesicles, testes, and the vas deferens. However, this antiandrogen also antagonizes less sex-specific effects of androgens, for example ossification of the epiphyseal cartilage, sebaceous gland function and skin thickness. Indications for CPA: Prostate cancer, androgen induced disorders of the skin (acne, seborrhoea, hirsutism, alopecia), precocious puberty and sexual disorders in men. Concerning sexual deviations clinical trials started in 1966. CPA leads to loss of libido and the ability to achieve erection, followed by the inability to achieve orgasm, after about 14 days of treatment (100-200 mg daily orally or 300 mg weekly i.m.). These effects are reversed in the same order as the onset. About 75 to 80% of patients respond to this therapy. CPA is generally well tolerated. Tiredness, lack of drive, listlessness and depressive moods have been reported as non-specific side-effects. Slight gynecomastia occurs in about 20% of patients. There are no good alternatives in this indication. Pure antiandrogens are unsuitable, because these are unable to inhibit libido sufficiently. Tranquilizers are not very effective, high doses of estrogens are associated with severe (cardiovascular) side effects. Orchidectomy is an irreversible intervention, LHRH analogues are associated with hot flushes and the initial increase in testosterone (flare phenomenon).

Abstract
1. Steroid hormones can affect spermatogenesis and thereby fertility directly and/or indirectly. All antigonadotropically active steroids inhibit spermatogenesis via inhibition of gonadotropin secretion, mainly that of H. Androgens and steroids occurring in the biosynthetic chain of testosterone synthesis have a direct promoting effect on spermatogenesis if applied in high doses. It has not been possible as yet to make clinical use of this positive effect since it is obviously not possible to achieve the necessary intratesticular androgen concentrations. 2. As concerns the different androgens and the steroids in the androgen biosynthetic chain, and also all synthetic anabolics, there is no parallelism between the direct spermatogenic activity, the androgenic activity and the antigonadotropic activity. 3. Estrogens and synthetic gestagens do not inhibit spermatogenesis directly at the testicular level. All effects of estrogens can be abolished experimentally by adequate substitution with gonadotropins or androgens, or a combination of androgens and gonadotropins. 4. Only those antiandrogens inhibit spermatogenesis with additional antigonadotropic properties (e.g. cyproterone acetate). Pure antiandrogens, like flutamide or cyproterone, have a slight and transient influence on spermatogenesis at the most. If at all, they merely cause transient subfertility. 5. Beside steroids and several centrally active pharmaceutics (e.g. psychotropic drugs and several antihypertensive compounds), only siloxanes and methallibur seem to affect spermatogenesis via inhibition of gonadotropin secretion. Other antispermatogenic agents act by inhibition of mitosis (Colchicine, alkylating agents) or presumably via damage of the Sertoli cells. 6. Based on present knowledge, contraception in men could be principally managed by administration of a) androgens alone, b) gestagen/androgen combinations, c) estrogen/androgen combinations, d) certain antiandrogens. 7. The difficulties of contraception in men by steroid hormones or steroid hormone combinations have been pointed out. As regards the usefulness of antiandrogens for contraception, no definite conclusions can be drawn at the moment. All non-steroidal inhibitors of spermatogenesis which have been found up to the present are not suitable because of toxic effects.

BACKGROUND AND STUDY AIMS We aimed to determine the feasibility of obtaining selective fluorescence of precancerous/cancerous lesions in the colon with a new fluorescence video endoscope system in combination with the selective photosensitizer precursor hexaminolevulinate (HAL), and to carry out a dose-finding study with evaluation of the optimal dose and application time. PATIENTS AND METHODS 12 patients with colorectal lesions underwent sensitization with locally applied HAL enemas in two concentrations (0.8 mmol and 1.6 mmol). The examination was conducted either 30 or 60 minutes after rectal administration of the sensitizer, using a special light source capable of delivering either white or blue excitation light. Red fluorescence induced by illumination with blue light was detected via a prototype fluorescence video colonoscope. Biopsies were taken from suspicious areas found with white or blue light. Corresponding endoscopic, fluorescence, and microscopic findings were compared. RESULTS Using histological findings as the gold standard, 52/53 of the premalignant/malignant lesions showed red fluorescence under the photodynamic diagnosis (PDD) examination; 38/53 were detected with white-light endoscopy. The PDD mode showed 28 % more polyps than did white-light endoscopic imaging. The greatest fluorescence intensity in precancerous lesions was found with retention for 60 minutes of 500 ml of 1.6 mmol HAL. CONCLUSIONS Administration of HAL enema induces selective lesion fluorescence and increases the lesion detection rate in patients with colorectal adenoma and early carcinoma.

Abstract
Knowledge on interplay between the cardiac molecular response to transplantation-induced stress and primary graft dysfunction (PGD) is limited. A cDNA array identified HIF-1, EGR-1, NAB-2, VEGF-A and uPA as mediators of cardiac tissue response to transplantation-induced stress. mRNA expression of these molecules was measured in left ventricular biopsies from 200 donors before and after aortic cross-clamping and at 10-, 30- and 60-min reperfusion by real-time RT-PCR. HIF-1alpha expression at two time points was significantly associated with PGD, as shown by univariate analysis, receiver operating characteristic curve and multivariate logistic regression. At a cut-off level of 200 arbitrary units, HIF-1alpha after aortic cross-clamping in donors (78% sensitivity, 83% specificity) and at 10-min reperfusion (85% sensitivity, 83% specificity) identified PGD. HIF-1alpha demonstrates the potential to be a predictive marker for PGD; however, as multiple factors were tested at different time points, prospective evaluation is clearly necessary to confirm this observation.

Abstract
In this study, we provide a molecular signature of highly enriched CD34+ cells from bone marrow of untreated patients with chronic myelogenous leukemia (CML) in chronic phase in comparison with normal CD34+ cells using microarrays covering 8746 genes. Expression data reflected several BCR-ABL-induced effects in primary CML progenitors, such as transcriptional activation of the classical mitogen-activated protein kinase pathway and the phosphoinositide-3 kinase/AKT pathway as well as downregulation of the proapoptotic gene IRF8. Moreover, novel transcriptional changes in comparison with normal CD34+ cells were identified. These include upregulation of genes involved in the transforming growth factorbeta pathway, fetal hemoglobin genes, leptin receptor, sorcin, tissue inhibitor of metalloproteinase 1, the neuroepithelial cell transforming gene 1 and downregulation of selenoprotein P. Additionally, genes associated with early hematopoietic stem cells (HSC) and leukemogenesis such as HoxA9 and MEIS1 were transcriptionally activated. Differential expression of differentiation-associated genes suggested an altered composition of the CD34+ cell population in CML. This was confirmed by subset analyses of chronic phase CML CD34+ cells showing an increase of the proportion of megakaryocyte-erythroid progenitors, whereas the proportion of HSC and granulocyte-macrophage progenitors was decreased in CML. In conclusion, our results give novel insights into the biology of CML and could provide the basis for identification of new therapeutic targets.

Abstract
2578 Background: Vaccine strategies that target or activate dendritic cells in order to elicit potent cellular immunity are currently the subject of intense research. Here we report that genetically engineered yeast expressing the full-length tumor associated antigen NY-ESO-1 are a versatile host for protein production eliciting MHC class I and II T-cell responses. Methods: The pYD1 yeast display vector was chosen for full length NY-Eso-1 protein (pNY-ESO-1) expression. NY-ESO-1 and SSX-2 (as control) protein were affinity purified on. IFN-g ELISPOT assays were performed in triplicates on nitrocellulose-lined 96-well plates. MHC class I cross-presentation of peptide epitopes was demonstrated by blocking T-cell responses against DCs. For this purpose, antigen or peptide pulsed DCs were labeled with different doses (100, 10, 1 μg/ml) of antibodies specific for HLA-A2/peptide complexes (HLA-A2/ NY-Eso-1157–165; 3M4E5) or an irrelevant antibody (specific for HLA-A2/IMP58–66) as control. Results: Highest level of NY-ESO-1 expression was detected on the cell wall of wt EBY100 strain with lower expression levels on PMT deficient strains PMT-2 and PMT-4. After protein feeding of immature DCs, NY-ESO-1 157–165 peptide cross-presentation was detected by 3M4E5 and an antigen-specific CD8+ T cell clone. There was a strong positive correlation between the amount of Aga2p-NY-ESO-1 protein (0–15μg/ml) and peptide presentation. Specific T-cell recognition of NY-Eso-1 157–165/HLA-A2 complexes was validated by blocking experiments with Fab 3M4E5. Pre-incubation of protein fed DCs with the antibody at different concentrations (0–100 μg/ml) resulted in a significant reduction (p< 0.05) of spot numbers. Efficient presentation and T-cell recognition of epitope 157–165 was only adequately detectable when protein produced by EBY100 wt yeast strain was used (p < 0.05). MHC class II presentation was studied in an autologous setting using a T-cell line recognising the NY-ESO-1 157–170 in HLA-DP4 context revealing that NY-ESO-1 protein produced in yeast was efficiently taken up and presented. Conclusions: Together, these data add further evidence that yeast expressing recombinant proteins can be used for vaccine purposes and that antigen uptake in APC depends on glycoslation of yeast expressed antigens. No significant financial relationships to disclose.
