Abstract
Human-based organ models can provide strong predictive value to investigate the tropism, virulence, and replication kinetics of viral pathogens. Currently, such models have received widespread attention in the study of SARS-CoV-2 causing the COVID-19 pandemic. Applicable to a large set of organoid models and viruses, we provide a step-by-step work instruction for the infection of human alveolar-like organoids with SARS-CoV-2 in this protocol collection. We also prepared a detailed description on state-of-the-art methodologies to assess the infection impact and the analysis of relevant host factors in organoids. This protocol collection consists of five different sets of protocols. Set 1 describes the protein extraction from human alveolar-like organoids and the determination of protein expression of angiotensin-converting enzyme 2 (ACE2), transmembrane serine protease 2 (TMPRSS2) and FURIN as exemplary host factors of SARS-CoV-2. Set 2 provides detailed guidance on the extraction of RNA from human alveolar-like organoids and the subsequent qPCR to quantify the expression level of ACE2, TMPRSS2, and FURIN as host factors of SARS-CoV-2 on the mRNA level. Protocol set 3 contains an in-depth explanation on how to infect human alveolar-like organoids with SARS-CoV-2 and how to quantify the viral replication by plaque assay and viral E gene-based RT-qPCR. Set 4 provides a step-by-step protocol for the isolation of single cells from infected human alveolar-like organoids for further processing in single-cell RNA sequencing or flow cytometry. Set 5 presents a detailed protocol on how to perform the fixation of human alveolar-like organoids and guides through all steps of immunohistochemistry and in situ hybridization to visualize SARS-CoV-2 and its host factors. The infection and all subsequent analytical methods have been successfully validated by biological replications with human alveolar-like organoids based on material from different donors.

Abstract
BACKGROUND Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) utilises the angiotensin-converting enzyme 2 (ACE2) transmembrane peptidase as cellular entry receptor. However, whether SARS-CoV-2 in the alveolar compartment is strictly ACE2-dependent and to what extent virus-induced tissue damage and/or direct immune activation determines early pathogenesis is still elusive. METHODS Spectral microscopy, single-cell/-nucleus RNA sequencing or ACE2 "gain-of-function" experiments were applied to infected human lung explants and adult stem cell derived human lung organoids to correlate ACE2 and related host factors with SARS-CoV-2 tropism, propagation, virulence and immune activation compared to SARS-CoV, influenza and Middle East respiratory syndrome coronavirus (MERS-CoV). Coronavirus disease 2019 (COVID-19) autopsy material was used to validate ex vivo results. RESULTS We provide evidence that alveolar ACE2 expression must be considered scarce, thereby limiting SARS-CoV-2 propagation and virus-induced tissue damage in the human alveolus. Instead, ex vivo infected human lungs and COVID-19 autopsy samples showed that alveolar macrophages were frequently positive for SARS-CoV-2. Single-cell/-nucleus transcriptomics further revealed nonproductive virus uptake and a related inflammatory and anti-viral activation, especially in "inflammatory alveolar macrophages", comparable to those induced by SARS-CoV and MERS-CoV, but different from NL63 or influenza virus infection. CONCLUSIONS Collectively, our findings indicate that severe lung injury in COVID-19 probably results from a macrophage-triggered immune activation rather than direct viral damage of the alveolar compartment.

Abstract
Epidemiological data demonstrate that Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) variants of concern (VOCs) Alpha and Delta are more transmissible, infectious, and pathogenic than previous variants. Phenotypic properties of VOC remain understudied. Here, we provide an extensive functional study of VOC Alpha replication and cell entry phenotypes assisted by reverse genetics, mutational mapping of spike in lentiviral pseudotypes, viral and cellular gene expression studies, and infectivity stability assays in an enhanced range of cell and epithelial culture models. In almost all models, VOC Alpha spread less or equally efficiently as ancestral (B.1) SARS-CoV-2. B.1. and VOC Alpha shared similar susceptibility to serum neutralization. Despite increased relative abundance of specific sgRNAs in the context of VOC Alpha infection, immune gene expression in infected cells did not differ between VOC Alpha and B.1. However, inferior spreading and entry efficiencies of VOC Alpha corresponded to lower abundance of proteolytically cleaved spike products presumably linked to the T716I mutation. In addition, we identified a bronchial cell line, NCI-H1299, which supported 24-fold increased growth of VOC Alpha and is to our knowledge the only cell line to recapitulate the fitness advantage of VOC Alpha compared to B.1. Interestingly, also VOC Delta showed a strong (595-fold) fitness advantage over B.1 in these cells. Comparative analysis of chimeric viruses expressing VOC Alpha spike in the backbone of B.1, and vice versa, showed that the specific replication phenotype of VOC Alpha in NCI-H1299 cells is largely determined by its spike protein. Despite undetectable ACE2 protein expression in NCI-H1299 cells, CRISPR/Cas9 knock-out and antibody-mediated blocking experiments revealed that multicycle spread of B.1 and VOC Alpha required ACE2 expression. Interestingly, entry of VOC Alpha, as opposed to B.1 virions, was largely unaffected by treatment with exogenous trypsin or saliva prior to infection, suggesting enhanced resistance of VOC Alpha spike to premature proteolytic cleavage in the extracellular environment of the human respiratory tract. This property may result in delayed degradation of VOC Alpha particle infectivity in conditions typical of mucosal fluids of the upper respiratory tract that may be recapitulated in NCI-H1299 cells closer than in highly ACE2-expressing cell lines and models. Our study highlights the importance of cell model evaluation and comparison for in-depth characterization of virus variant-specific phenotypes and uncovers a fine-tuned interrelationship between VOC Alpha- and host cell-specific determinants that may underlie the increased and prolonged virus shedding detected in patients infected with VOC Alpha.

Background
Endogenous Cushing’s syndrome (CS) results in increased cardiovascular morbidity and mortality. This risk seems to be lower in patients with incidentally discovered mild autonomous cortisol secretion (MACS) but without the clinical features of CS. We aimed to describe and compare the cardiac morphology and function in patients with overt CS and MACS to a representative sample of a local prospective population-based cohort (STAAB).
Methods/Results: We comprehensively characterized 40 patients with overt CS (mean age 47 ± 13 years, 75% women) and 18 patients with MACS (62 ± 11 years, 56% women; both p ≤ 0.001 when compared to CS) including detailed transthoracic echocardiography. Logistic regression adjusted for age and sex showed no significant differences between both groups regarding body mass index (BMI), systolic and diastolic blood pressure (BP), lipids, HbA1c, and echocardiographic parameters of cardiac morphology and function (table). The comparison with STAAB participants (n = 4965, 55 ± 12 years, 52% women; logistic regression adjusted for age and sex) revealed significantly higher BMI, triglycerides, HbA1c, and diastolic but not systolic BP (table). Compared to STAAB participants, patients exhibited a smaller left ventricle (LV) with thicker septal and posterior walls, and a less favorable diastolic function. LV ejection fraction (LVEF) was higher, although longitudinal contraction, measured by tricuspid annular plane systolic excursion (TAPSE), and LV global longitudinal strain (GLS) were lower in both ventricles compared to STAAB participants (table).
Conclusion
Patients with both MACS or CS exhibited a compromised metabolic profile and diastolic function pattern when compared to a population-based cohort. Higher LVEF despite lower GLS suggests a compensatory increase in LV radial contraction in states of hypercortisolism. Cardiac impairment was similar in patients with CS or MACS suggesting an adverse effect of hypercortisolism even at clinically inconspicuous levels. Abstract Figure.

Abstract
Viruses manipulate cellular metabolism and macromolecule recycling processes like autophagy. Dysregulated metabolism might lead to excessive inflammatory and autoimmune responses as observed in severe and long COVID-19 patients. Here we show that SARS-CoV-2 modulates cellular metabolism and reduces autophagy. Accordingly, compound-driven induction of autophagy limits SARS-CoV-2 propagation. In detail, SARS-CoV-2-infected cells show accumulation of key metabolites, activation of autophagy inhibitors (AKT1, SKP2) and reduction of proteins responsible for autophagy initiation (AMPK, TSC2, ULK1), membrane nucleation, and phagophore formation (BECN1, VPS34, ATG14), as well as autophagosome-lysosome fusion (BECN1, ATG14 oligomers). Consequently, phagophore-incorporated autophagy markers LC3B-II and P62 accumulate, which we confirm in a hamster model and lung samples of COVID-19 patients. Single-nucleus and single-cell sequencing of patient-derived lung and mucosal samples show differential transcriptional regulation of autophagy and immune genes depending on cell type, disease duration, and SARS-CoV-2 replication levels. Targeting of autophagic pathways by exogenous administration of the polyamines spermidine and spermine, the selective AKT1 inhibitor MK-2206, and the BECN1-stabilizing anthelmintic drug niclosamide inhibit SARS-CoV-2 propagation in vitro with IC50 values of 136.7, 7.67, 0.11, and 0.13 μM, respectively. Autophagy-inducing compounds reduce SARS-CoV-2 propagation in primary human lung cells and intestinal organoids emphasizing their potential as treatment options against COVID-19.

Abstract
Detailed knowledge of the molecular biology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is crucial for understanding of viral replication, host responses, and disease progression. Here, we report gene expression profiles of three SARS-CoV- and SARS-CoV-2-infected human cell lines. SARS-CoV-2 elicited an approximately two-fold higher stimulation of the innate immune response compared to SARS-CoV in the human epithelial cell line Calu-3, including induction of miRNA-155. Single-cell RNA sequencing of infected cells showed that genes induced by virus infections were broadly upregulated, whereas interferon beta/lambda genes, a pro-inflammatory cytokines such as IL-6, were expressed only in small subsets of infected cells. Temporal analysis suggested that transcriptional activities of interferon regulatory factors precede those of nuclear factor κB. Lastly, we identified heat shock protein 90 (HSP90) as a protein relevant for the infection. Inhibition of the HSP90 activity resulted in a reduction of viral replication and pro-inflammatory cytokine expression in primary human airway epithelial cells.

Abstract
OBJECTIVE The present study aimed to characterize involuntary psychiatric admissions and coercive measures within psychiatric hospitals regarding their temporal development and processual aspects. Moreover, the influence of socio-economic factors on involuntary admissions and coercive measures was investigated. METHODS Different data sets from the federal state of North-Rhine Westphalia (NRW) were used in this study. In addition to a survey in which n = 33 hospitals responded (40.7%), official data from the Federal Health Ministry were analysed over a decade regarding involuntary admissions and coercive measures. These data were available for all n = 54 districts, respectively, all n = 81 psychiatric hospitals in NRW. Datasets were mainly analysed comparing different socio-economic clusters. RESULTS The hospital admission rate increased significantly over time (from 1.12 to 1.34 per 1000 inhabitants) within ten years. However, whereas the admission rates differed significantly between socio-economic clusters, the amount of coercive measures used in the hospitals did not. Compared to general psychiatry and addiction medicine, geriatric psychiatry had the highest amount of involuntary admissions (12.2% under public law, 14.1% under civil law). Furthermore, most coercive measures lasted at least an hour. CONCLUSION It seems that, despite intense discussions and enhanced efforts to reduce coercion, there are still some neglected aspects, such as the need for coercive measures and their duration, particularly in the geriatric psychiatric setting. In addition, the results show that further approaches to prevent involuntary admissions are needed to address other stakeholders beyond the hospitals and further aspects of the socio-economic environment.

Abstract
High‐grade serous ovarian cancer (HGSOC) likely originates from the fallopian tube (FT) epithelium. Here, we established 15 organoid lines from HGSOC primary tumor deposits that closely match the mutational profile and phenotype of the parental tumor. We found that Wnt pathway activation leads to growth arrest of these cancer organoids. Moreover, active BMP signaling is almost always required for the generation of HGSOC organoids, while healthy fallopian tube organoids depend on BMP suppression by Noggin. Fallopian tube organoids modified by stable shRNA knockdown of p53, PTEN, and retinoblastoma protein (RB) also require a low‐Wnt environment for long‐term growth, while fallopian tube organoid medium triggers growth arrest. Thus, early changes in the stem cell niche environment are needed to support outgrowth of these genetically altered cells. Indeed, comparative analysis of gene expression pattern and phenotypes of normal vs. loss‐of‐function organoids confirmed that depletion of tumor suppressors triggers changes in the regulation of stemness and differentiation.

Abstract
BACKGROUND Liver resection is the only curative therapeutic option for intrahepatic cholangiocarcinoma (ICC), but the approach to recurrent ICC is controversial. This study analysed the outcome of liver resection in patients with recurrent ICC. METHODS Demographic, radiological, clinical, operative, surgical pathological and follow-up data for all patients with a final surgical pathological diagnosis of ICC treated in a tertiary referral centre between 2001 and 2015 were collected retrospectively and analysed. RESULTS A total of 190 patients had liver resection for primary ICC. The 1-, 3- and 5-year overall survival (OS) rates were 74·8, 56·6 and 37·9 per cent respectively. Independent determinants of OS were age 65 years or above (hazard ratio (HR) 2·18, 95 per cent c.i. 1·18 to 4·0; P = 0·012), median tumour diameter 5 cm or greater (HR 2·87, 1·37 to 6·00; P = 0·005), preoperative biliary drainage (HR 2·65, 1·13 to 6·20; P = 0·025) and local R1-2 status (HR 1·90, 1·02 to 3·53; P = 0·043). Recurrence was documented in 87 patients (45·8 per cent). The mean(s.d.) survival time after recurrence was 16(17) months. Independent determinants of recurrence were median tumour diameter 5 cm or more (HR 1·71, 1·09 to 2·68; P = 0·020), high-grade (G3-4) tumour (HR 1·63, 1·04 to 2·55; P = 0·034) and local R1 status (HR 1·70, 1·09 to 2·65; P = 0·020). Repeat resection with curative intent was performed in 25 patients for recurrent ICC, achieving a mean survival of 25 (95 per cent c.i. 16 to 34) months after the diagnosis of recurrence. Patients deemed to have unresectable disease after recurrence received chemotherapy or chemoradiotherapy alone, and had significantly poorer survival. CONCLUSION Patients with recurrent ICC may benefit from repeat surgical resection.

Abstract
Abstract
As the WHO-Health-in-all-Policies-concept suggests many of the health-related aspects of the social, physical and economic environments can be modified within the community setting. In reality, developing and implementing population-based health initiatives is often challenging for both communities and researchers. To guide future efforts of community health initiatives, we systematically analyzed challenges we encountered and the lessons learned.
We systematically reviewed daily logbooks, meeting minutes and press releases about the initiative to identify successes, unexpected challenges and barriers in its implementation. Comments from two reflective workshops held in the partner community identified additional areas of knowledge. Retrospective content analysis of these sources uncovered emerging process-related themes.
Success was evident in a high degree of citizen participation in initiative-related forums. Challenges included a greater need to a) develop a common vision before starting initiative activities, b) establish an effective collaboration between community residents and our team, c) create more transparent lines of communication, foster trust and better manage community expectations. Establishing a project office in the community for regular updates, trust building and partnering with a professional communication agency were key steps that helped turn some challenges into successes. Barriers identified were missing resources both within the community and our team, a limited time period and limited possibilities of reach into all systems within the community (e.g. kindergartens).
The use of the method of retrospective process analysis helped to uncover detailed insights into the operational implementation process of a community health initiative. These insights serve as a transfer of practical knowledge, which intends to enable researchers and practioneers within communities to plan and conduct their community health initiatives to large success.
Key messages
Analyzing the process of health initiatives retrospectively uncovers detailed insights into implementation processes and helps to understand successes, challenges and barriers of the initiative. Insights into the implementation process of health initiatives function as guidance to other researchers and practioneers to support future efforts in the field of community health.

Abstract
Abstract
Background
Neighborhoods and their characteristics play a key role for establishing and maintaining health and wellbeing of their residents. However, before programs promoting health and wellbeing in the neighborhood can be planned and implemented, it is necessary to identify local needs for action. This is especially important for the stakeholders that work in the neighborhood (e.g., employees of the local community, headmasters of schools). We thus developed exemplary for Herzogenried -a neighborhood in the German city of Mannheim- a barometer that aims to assess and monitor health and wellbeing in the neighborhood and indicates potential needs for action.
Methods
We conducted a detailed literature search to identify indicators that were associated with health and wellbeing in neighborhoods. Based on the search we created a primary list of indicators, which we presented and discussed during 15 meetings with a total of 26 different stakeholders. Available data on the indicators agreed on were checked for accuracy, statistically processed, and visualized for incorporation into the barometer.
Results
The barometer consists of the following eight dimensions which in total include 80 indicators: population structure, population development, household structure, material wellbeing, education, family and upbringing, health, and personal security. The barometer also includes a map that displays structural characteristics of the neighborhood such as physicians, schools, supermarkets. An important challenge we faced was the availability of indicators as some of them were only accessible at the community level or for specific age groups.
Conclusions
The barometer offers a comprehensive overview on the neighborhood, provides first hints for the local stakeholders on needs for action, and helps to prioritize the issues that should be addressed to promote health and wellbeing in Herzogenried. It will also serve as a prototype for other neighborhoods in the future.
Key messages
The barometer was planned to serve as a transferable tool to identify and prioritize action steps for neighborhood development and to help promoting health and wellbeing of their residents. As the barometer displays indicators relevant for various community stakeholders it can serve to identify joint goals and thus foster stronger trans-sectoral collaboration at the neighborhood level.

Abstract
We used Bayesian evolutionary analysis to study linguistic data and infer phylogenetic trees of language evolution. Languages were encoded as binary strings indicating the presence or absence of members of cognate classes, the equivalence of classes of words with similar meaning, and shared ancestry. These strings formed the alignment data used to compute the posterior likelihood of a tree with respect to Bayes’ formula. Informative priors are crucial for testing hypotheses regarding the age of common ancestry and divergence times and should include as much available information as possible. Here, we investigated the birth–death process as a method to construct tree priors specifically suitable for modeling the evolution of cognate data. To test these models, we will use a dataset of the languages from Vanuatu, an island nation featuring world’s highest language density.

Abstract
The large number of nanomaterial-based applications emerging in the materials and life sciences and the foreseeable increasing use of these materials require methods that evaluate and characterize the toxic potential of these nanomaterials to keep safety risks to people and environment as low as possible. As nanomaterial toxicity is influenced by a variety of parameters like size, shape, chemical composition, and surface chemistry, high throughput screening (HTS) platforms are recommended for assessing cytotoxicity. Such platforms are not yet available for genotoxicity testing. Here, we present first results obtained for application-relevant nanomaterials using an automatable genotoxicity platform that relies on the quantification of the phosphorylated histone H2AX (γ-H2AX) for detecting DNA double strand breaks (DSBs) and the automated microscope system AKLIDES® for measuring integral fluorescence intensities at different excitation wavelengths. This platform is used to test the genotoxic potential of 30 nm-sized citrate-stabilized gold nanoparticles (Au-NPs) as well as micellar encapsulated iron oxide nanoparticles (FeOx-NPs) and different cadmium (Cd)-based semiconductor quantum dots (QDs), thereby also searching for positive and negative controls as reference materials. In addition, the influence of the QD shell composition on the genotoxic potential of these Cd-based QDs was studied, using CdSe cores as well as CdSe/CdS core/shell and CdSe/CdS/ZnS core/shell/shell QDs. Our results clearly revealed the genotoxicity of the Au-NPs and its absence in the FeOx-NPs. The genotoxicity of the Cd-QDs correlates with the shielding of their Cd-containing core, with the core/shell/shell architecture preventing genotoxicity risks. The fact that none of these nanomaterials showed cytotoxicity at the chosen particle concentrations in a conventional cell viability assay underlines the importance of genotoxicity studies to assess the hazardous potential of nanomaterials.

Abstract
OBJECTIVE Obstructive eustachian tube dysfunction (OETD) affects up to 5% of adults; however, available treatment strategies have limitations. It was previously reported that balloon dilation of the eustachian tube (BDET) with the eustachian tube balloon catheter + medical management (MM) results in a significantly higher proportion of subjects with normalized tympanograms versus MM alone at 6- and 24-week follow-up. The current analysis extends these initial findings by investigating the durability of BDET + MM treatment outcomes through 52 weeks. STUDY DESIGN Prospective cohort follow-up study from the treatment group in a previously reported multicenter randomized controlled trial. SETTING Twenty-one investigational sites across the United States. SUBJECTS AND METHODS Here we report on secondary and exploratory endpoints for patients with OETD who previously failed MM and were randomized to the BDET + MM cohort. Analyses of tympanogram outcomes are reported by ear, unless specified otherwise, as a more accurate measure of durability of the procedure over time. RESULTS Among subjects randomized to BDET + MM, the overall number with normalized tympanograms and ETDQ-7 scores (Eustachian Tube Dysfunction Questionnaire-7) remained comparable to those reported at 6- versus 52-week follow-up: tympanograms, 73 of 143 (51.0%) versus 71 of 128 (55.5%); ETDQ-7, 79 of 142 (55.6%) versus 71 of 124 (57.3%). The overall number of ears with normalized tympanograms also remained comparable, with 117 of 204 (57%) versus 119 of 187 (63.6%). CONCLUSIONS The present study suggests that the beneficial effects of BDET + MM on tympanogram normalization and symptoms of subjects with refractory OETD demonstrate significant durability that is clinically relevant through 52 weeks.

Abstract
Ayurveda is a traditional Indian system of medicine that is more than 3000 years old, consisting mostly of a specific diet, oily infusions mainly in the area of the head, enemas, medicinal plants and yoga. It is based on a naturopathic and anthropological belief in association with the hinduistic religion. Ayurveda has been practiced very successfully in India but so far it has only been insufficiently appreciated by western medicine, especially psychiatry. An exception is Scharfetter from Zürich who wrote a review article on this topic in 1976. Nevertheless, it is probable that particularly the immunological mechanisms of psychotic and affective disorders can be influenced by the application of ayurvedic methods; however, the empirical data source, particularly with respect to randomized controlled trials and meta-analyses regarding psychiatric disorder symptoms is limited. Even if Ayurveda is applied in a highly individualized manner, this should be rapidly improved for further evidential assessment. First positive experiences in the neuropsychiatric field in Germany are already available.

Abstract
An endogenous molecular clockwork drives various cellular pathways including metabolism and the cell cycle. Its dysregulation is able to prompt pathological phenotypes including cancer. Besides dramatic metabolic alterations, cancer cells display severe changes in the clock phenotype with likely consequences in tumor progression and treatment response. In this study, we use a comprehensive systems-driven approach to investigate the effect of clock disruption on metabolic pathways and its impact on drug response in a cellular model of colon cancer progression. We identified distinctive time-related transcriptomic and metabolic features of a primary tumor and its metastatic counterpart. A mapping of the expression data to a comprehensive genome-scale reconstruction of human metabolism allowed for the in-depth functional characterization of 24 h-oscillating transcripts and pointed to a clock-driven metabolic reprogramming in tumorigenesis. In particular, we identified a set of five clock-regulated glycolysis genes, ALDH3A2, ALDOC, HKDC1, PCK2, and PDHB with differential temporal expression patterns. These findings were validated in organoids and in primary fibroblasts isolated from normal colon and colon adenocarcinoma from the same patient. We further identified a reciprocal connection of HKDC1 to the clock in the primary tumor, which is lost in the metastatic cells. Interestingly, a disruption of the core-clock gene BMAL1 impacts on HKDC1 and leads to a time-dependent rewiring of metabolism, namely an increase in glycolytic activity, as well as changes in treatment response. This work provides novel evidence regarding the complex interplay between the circadian clock and metabolic alterations in carcinogenesis and identifies new connections between both systems with pivotal roles in cancer progression and response to therapy.

Abstract
PURPOSE To investigate the value of contrast-enhanced ultrasound (CEUS) in histologic prediction of focal liver lesions after liver transplantation. MATERIALS AND METHODS 10 focal liver lesions in 10 patients after liver transplantation were scanned using CEUS and the CEUS results were compared with the histopathological results. RESULTS Among 10 focal liver lesions, 7 proofed to be histopathological benign and 3 lesions proofed to be histopathological malignant. All lesions (100%) were correctly report as benign or malignant in the report of the CEUS examination. CONCLUSION CEUS can be helpful in the differentiation of benign and malignant focal liver lesions in patients after liver transplantation and can be used in clinical management of focal liver lesions.

Abstract
PURPOSE To analyse the diagnostic performance of contrast-enhanced ultrasound (CEUS) in patients with vascular complications and transplant rejection compared to histopathological results. MATERIALS AND METHODS Our study consisted of 45 retrospectively analysed patients that underwent liver transplantations between January 1993 and December 2015 and developed post-transplant vascular complications with transplant rejection. CEUS examinations took place between September 2006 and December 2015. CEUS findings were correlated with histopathological results. RESULTS CEUS showed a sensitivity of 61.5%, a specificity of 100.0%, a positive predictive value (PPV) of 100.0% and a negative predictive value (NPV) of 86,5% in the detection of vascular complications with post-transplant rejection. 5 examinations were reported as normal whereas the histopathological result showed a transplant rejection (false-negative). CONCLUSION CEUS might be a useful additional non-invasive technique for the assessment of vascular complications with post-transplant rejection in patients after liver transplantation.

Abstract
Complex trends in occupancy determined by many influencing factors, clear state-specific differences in imprisonment practices as well as recently implemented statutory alterations to the appropriate paragraphs in criminal law, underline the necessity for qualitative high-grade concomitant research of German forensic commitment; however, neither the structural prerequisites nor an adequate data situation are currently present in order to do justification to this aim. Not even the total number of patients currently accommodated in forensic commitment can be elucidated from the publicized (partial) statistics. This consensus paper, which was formulated by three research institutes active at the state level, describes the limited possibilities for current forensic healthcare research and raises the demand for a nationwide uniform data situation on patients in forensic commitment. Furthermore, how the appropriate elicitation instrument should be organizationally and structurally achieved, is sketched from a scientific perspective. This article aims at initiating a discussion on a sustainable improvement in the prerequisites for healthcare research in German forensic commitment and targets a sensitization of decision makers in politics and administration for this topic.

Abstract
OBJECTIVES/HYPOTHESIS To assess balloon dilation of the Eustachian tube with Eustachian tube balloon catheter in conjunction with medical management as treatment for Eustachian tube dilatory dysfunction. STUDY DESIGN In this prospective, multicenter, randomized, controlled trial, we assigned, in a 2:1 ratio, patients age 22 years and older with Eustachian tube dilatory dysfunction refractory to medical therapy to undergo balloon dilation of the Eustachian tube with balloon catheter in conjunction with medical management or medical management alone. METHODS The primary endpoint was normalization of tympanogram at 6 weeks. Additional endpoints were normalization of Eustachian Tube Dysfunction Questionaire-7 symptom scores, positive Valsalva maneuver, mucosal inflammation, and safety. RESULTS Primary efficacy results demonstrated superiority of balloon dilation of the Eustachian tube with balloon catheter + medical management compared to medical management alone. Tympanogram normalization at 6-week follow-up was observed in 51.8% (72/139) of investigational patients versus 13.9% (10/72) of controls (P < .0001). Tympanogram normalization in the treatment group was 62.2% after 24 weeks. Normalization of Eustachian Tube Dysfunction Questionaire-7 Symptom scores at 6-week follow-up was observed in 56.2% (77/137) of investigational patients versus 8.5% (6/71) controls (P < .001). The investigational group also demonstrated substantial improvement in both mucosal inflammation and Valsalva maneuver at 6-week follow-up compared to controls. No device- or procedure-related serious adverse events were reported for those who underwent balloon dilation of the Eustachian tube. CONCLUSIONS This study demonstrated superiority of balloon dilation of the Eustachian tube with balloon catheter + medical management compared to medical management alone to treat Eustachian tube dilatory dysfunction in adults.

Abstract
OBJECTIVES To determine the inpatient management for patients with acute idiopathic facial palsy (IFP) in Thuringia, Germany. DESIGN Population-based study. SETTING All inpatients with IFP in all hospitals with departments of otolaryngology and neurology in 2012, in the German federal state, Thuringia. MAIN OUTCOME MEASURES Patients' characteristics and treatment were compared between departments, and the probability of recovery was tested. RESULTS A total of 291 patients were mainly treated in departments of otolaryngology (55%) and neurology (36%). Corticosteroid treatment was the predominant therapy (84.5%). The probability to receive a facial nerve grading (odds ratio [OR=12.939; 95% confidence interval [CI]=3.599 to 46.516), gustatory testing (OR=6.878; CI=1.064 to 44.474) and audiometry (OR=32.505; CI=1.485 to 711.257) was significantly higher in otolaryngology departments, but lower for cranial CT (OR=0.192; CI=0.061 to 0.602), cerebrospinal fluid examination (OR=0.024; CI=0.006 to 0.102). A total of 131 patients (45%) showed a recovery to House-Brackmann grade≤II. A pathological stapedial reflex test (Hazard ratio [HR]=0.416; CI=0.180 to 0.959) was the only independent diagnostic predictor of worse outcome. Prednisolone dose >500 mg (HR=0.579; CI 0.400 to 0.838) and no adjuvant physiotherapy (HR=0.568; CI=0.407 to 0.794) were treatment-related predictors of worse outcome. CONCLUSIONS Inpatient treatment of IFP seems to be highly variable in daily practice, partly depending on the treating discipline and despite the availability of evidence-based guidelines. The population-based recovery rate was worse than reported in clinical trials.

Abstract
PURPOSE To evaluate the sensitivity and specificity of contrast-enhanced ultrasound (CEUS) and computed tomography (CT) in the diagnosis of malignancies after liver transplantation. MATERIALS AND METHODS A total of 23 patients with suspicious liver masses after liver transplantation with initial imaging series between September 2006 and September 2015 were statistically analysed. CEUS and CT were compared in their diagnosis of malignancy with CT being the gold standard. Out of 23 patients 9 patients showed malignant masses in CT, which could also be detected in 7 out 9 of cases using CEUS. RESULTS CEUS showed a sensitivity of 77.8%, a specificity of 100.0%, a positive predictive value (PPV) of 100.0% and a negative predictive value (NPV) of 87,5% in comparison with CT being the gold standard. In 2 cases CT showed a malignancy, contrary to the CEUS examination that was reported as normal. CONCLUSION CEUS seems to be an alternative option for the evaluation of malignant masses in liver transplant patients. CEUS shows a high specificity and PPV in the detection of malignant liver masses.

Abstract
BACKGROUND The symptom "delusions" is a central psychopathological symptom in psychiatric diseases. Since the beginning of psychiatry various disciplines have attempted to explain and understand delusions but even now no generally accepted definition of this phenomenon exists. AIM A comprehensive review of current psychopathological and neurobiological theories of delusions is given. MATERIAL AND METHODS PubMed and Google scholar searches were performed using the keywords "delusion", "psychodynamic" and "neurobiology", both in English and German. Relevant German textbooks of psychiatry were also included. DISCUSSION A differentiated perspective of the phenomenon of delusions appears to be necessary to approach this complex and fascinating symptom. A one-dimensional approach does not do justice to the complexity of delusions. The various explanatory approaches can increasingly be linked to each other and are no longer considered to be mutually exclusive.

Abstract
PURPOSE To compare the sensitivity and specificity of contrast-enhanced ultrasound (CEUS) and magnetic resonance imaging (MRI) in the evaluation of unclear renal lesions to the histopathological outcome. MATERIALS AND METHODS A total of 36 patients with a single unclear solid renal lesion with initial imaging studies between 2005 and 2015 were included. CEUS and MRI were used for determining malignancy or benignancy and initial findings were correlated with the histopathological outcome. Out of the 36 renal masses a total of 28 lesions were malignant (77.8%) and 8 were found to be benign (22.2%). Diagnostic accuracy was testes by using the histopathological diagnosis as the gold standard. RESULTS CEUS showed a sensitivity of 96.4%, a specificity of 100.0%, a positive predictive value (PPV) of 100.0% and a negative predictive value (NPV) of 88,9%. MRI showed a sensitivity of 96.4%, a specificity of 75.0%, a PPV of 93.1% and a NPV of 85.7%. Out of the 28 malignant lesions a total of 18 clear cell renal carcinomas, 6 papillary renal cell carcinomas and 4 other malignant lesions, e.g. metastases, were diagnosed. Out of the 8 benign lesions a total 3 angiomyolipomas, 2 oncocytomas, 1 benign renal cyst and 2 other benign lesions, e.g. renal adenomas were diagnosed. Using CEUS, 1 lesion was falsely identified as benign. Using MRI, 2 lesions were falsely identified as benign and 1 lesion was falsely identified as malignant. CONCLUSION CEUS is an useful method which can be additionally used to clinically differentiate between malignant and benign renal lesions. CEUS shows a comparable sensitivity, specificity, PPV and NPV to MRI. In daily clinical routine, patients with contraindications for other imaging modalities can particularly benefit using this method.

Abstract
Bullous autoimmune diseases are organ-specific disorders characterized by an autoantibody-mediated blistering of skin and mucous membranes. The detection of tissue-bound and serum autoantibodies is prerequisite for the diagnosis of autoimmune blistering diseases. The individual entities of this group may be difficult to differentiate on clinical grounds alone. An accurate diagnosis is however important for prognosis and therapy. A preliminary diagnostic step includes direct and indirect immunofluorescence microscopy, which provide information about the binding pattern and isotype of autoantibodies and allow the diagnosis of the autoimmune blistering disease. Subsequent characterization of the molecular specificity of autoantibodies is necessary for the exact classification of autoimmune bullous dermatoses. The quantitative measurement of autoantibodies against structural proteins of the skin may be often used to assess disease severity at follow-up.

Abstract
Diagnosis of cutaneous forms of lupus erythematosus (LE), including chronic discoid LE (CDLE) and subacute cutaneous LE (SCLE), is usually based on characteristic clinical and histopathological findings. We aimed to visualize morphological changes in lesions of cutaneous LE using optical coherence tomography (OCT), and to correlate the OCT findings with histopathology. Six patients with CDLE and five patients with SCLE were investigated. Prior to skin biopsy, OCT assessment was performed on previously marked lesions. The images of OCT and corresponding histology were evaluated side-by-side on the PC screen. The thickening and disruption of the entrance signal in OCT images correlated with the hyperkeratosis which was observed in the histological sections. Atrophy of the epidermis, which was demonstrated by histology, could also be detected in the OCT pictures showing a thinned layer below the entrance signals. On OCT, a patchy reduction of reflectivity was observed in the upper dermis corresponding to dense patchy, partly lichenoid, lymphocytic infiltrates and oedema of the upper dermis. Furthermore, OCT images displayed increased signal-free cavities which histopathologically corresponded to dilated vessels in the upper dermis. All OCT parameters studied significantly (P < 0.05) correlated with histopathological features as indicated by coefficients of correlation ranging from 0.55 to 0.94. OCT enables to demonstrate micromorphological changes in cutaneous LE which correlate with histopathological findings. Nevertheless, the current technique does not allow one to visualize definite diagnostic features of cutaneous LE. However, OCT may be a promising method for objective monitoring of LE activity and treatment effects over time in vivo
