Abstract
INTRODUCTION Theoretical frameworks of behavioral addictions mostly acknowledge the role of stress in the development and maintenance of these disorders, models of compulsive buying-shopping disorder (CBSD) however rarely incorporated stress. The association between stress and CBSD has not been reviewed yet. METHODS A scoping review was conducted to evaluate empirical results on the association between stress and CBSD. A comprehensive search string was employed in three databases. RESULTS 16 studies were included. Correlative studies suggested significant correlations between general perceived stress and CBSD symptom severity. Studies involving mean comparisons found higher general perceived stress levels in persons with problematic buying-shopping behavior/CBSD compared to control participants (large effects). Mixed results were found in studies involving regression/structural equation models and ecological momentary assessments. One study with a stress/negative mood induction observed more CBSD symptoms in a high stress group compared to a low stress group. DISCUSSION The studies are heterogeneous concerning design, samples and measures. Only very few studies surpass the level of cross-sectional correlative data which limits the ability to draw clear conclusions. Future research should study the impact of experimentally induced stress on CBSD symptoms, examine the relationship between stress and CBSD longitudinally and assess objective stress markers.

Abstract
We investigate the subsurface composition of turbid materials at the micro scale by means of a portable non-invasive technique, micro-spatially offset Raman spectroscopy (micro-SORS), combined with shifted excitation Raman difference spectroscopy (SERDS). This combination enables the microscale layer analysis and allows to deal effectively with highly fluorescing samples as well as ambient light, all in a form of an in-house portable prototype device optimised for applications in heritage science. The instrument comprises ability to simultaneously collect multiple spectra by means of an optical fibre bundle, thus reducing the dead time and simplifying the ease of deployment of the technique. The performance of the synergy between micro-SORS and 785 nm SERDS dual-wavelength diode laser is demonstrated on a stratified mock-up painting samples including highly fluorescing painted layers. This instrumental approach could be ground-breaking in heritage science, due to the largely unmet need of analysing the molecular composition of subsurface of artworks non-invasively and in situ, and in the presence of fluorescent background and ambient light. Moreover, many other fields are expected to benefit from this technological advancement such as solar energy, forensic and food analytical areas.

Abstract
BACKGROUND Dyspnoea is a common symptom of respiratory disease. However, data on its prevalence in general populations and its association with lung function are limited and are mainly from high-income countries. The aims of this study were to estimate the prevalence of dyspnoea across several world regions, and to investigate the association of dyspnoea with lung function. METHODS Dyspnoea was assessed, and lung function measured in 25,806 adult participants of the multinational Burden of Obstructive Lung Disease study. Dyspnoea was defined as ≥2 on the modified Medical Research Council (mMRC) dyspnoea scale. The prevalence of dyspnoea was estimated for each of the study sites and compared across countries and world regions. Multivariable logistic regression was used to assess the association of dyspnoea with lung function in each site. Results were then pooled using random-effects meta-analysis. RESULTS The prevalence of dyspnoea varied widely across sites without a clear geographical pattern. The mean prevalence of dyspnoea was 13.7 % (SD=8.2 %), ranging from 0 % in Mysore (India) to 28.8 % in Nampicuan-Talugtug (Philippines). Dyspnoea was strongly associated with both spirometry restriction (FVC CONCLUSION The prevalence of dyspnoea varies substantially across the world and is strongly associated with lung function impairment. Using the mMRC scale in epidemiological research should be discussed.

Abstract
INTRODUCTION Given the lack of research on the relationship of post-surgery dumping syndrome and eating disturbances, the purpose of the present longitudinal study was to investigate whether dumping after obesity surgery is associated with pre-/postoperative eating disorder symptoms or addiction-like eating beyond the type of surgery, gender, health-realted quality of life (HRQoL) and anxiety/depressive symptoms. METHODS The study included 220 patients (76% women) before (t0) and 6 months after (t1) obesity surgery (sleeve gastrectomy [n = 152], Roux-en-Y gastric bypass [n = 53], omega loop gastric bypass [n = 15]). The Sigstad Dumping Score was used to assess post-surgery dumping syndrome. Participants further answered the Eating Disorder Examination Questionnaire (EDE-Q), Yale Food Addiction Scale 2.0 (YFAS 2.0), Short-Form Health Survey (SF-12), and Hospital Anxiety and Depression Scale (HADS) at t0 and t1. RESULTS The point prevalence of symptoms suggestive of post-surgery dumping syndrome was 33%. Regression analyses indicate an association of dumping with surgical procedure (bypass), female gender, reduced HRQoL, more anxiety/depressive symptoms, and potentially with binge eating but not with eating disorder symptoms in general or with addiction-like eating. CONCLUSION The current study failed to show a close relationship between the presence of self-reported dumping syndrome and eating disorder symptoms or addiction-like eating following obesity surgery. Further studies with longer follow-up periods should make use of clinical interviews to assess psychosocial variables and of objective measures to diagnose dumping in addition to standardized self-ratings.

Abstract
Introduction: The surgical treatment of degenerative spondylolisthesis with accompanying spinal stenosis focuses mainly on decompression of the spinal canal with or without additional fusion by means of a dorsal spondylodesis. Currently, one main decision criterion for additional fusion is the presence of instability in flexion and extension X-rays. In cases of mild and stable spondylolisthesis, the optimal treatment remains a subject of ongoing debate. There exist different opinions on whether performing a fusion directly together with decompression has a potential benefit for patients or constitutes overtreatment. As X-ray images do not provide any information about internal biomechanical forces, computer simulation of individual patients might be a tool to gain a set of new decision criteria for those cases. Methods: To evaluate the biomechanical effects resulting from different decompression techniques, we developed a lumbar spine model using forward dynamic-based multibody simulation (FD_MBS). Preoperative CT data of 15 patients with degenerative spondylolisthesis at the level L4/L5 who underwent spinal decompression were identified retrospectively. Based on the segmented vertebrae, 15 individualized models were built. To establish a reference for comparison, we simulated a standardized flexion movement (intact) for each model. Subsequently, we performed virtual unilateral and bilateral interlaminar fenestration (uILF, bILF) and laminectomy (LAM) by removing the respective ligaments in each model. Afterward, the standardized flexion movement was simulated again for each case and decompression method, allowing us to compare the outcomes with the reference. This comprehensive approach enables us to assess the biomechanical implications of different surgical approaches and gain valuable insights into their effects on lumbar spine functionality. Results: Our findings reveal significant changes in the biomechanics of vertebrae and intervertebral discs (IVDs) as a result of different decompression techniques. As the invasiveness of decompression increases, the moment transmitted on the vertebrae significantly rises, following the sequence intact ➝ uILF ➝ bILF ➝ LAM. Conversely, we observed a reduction in anterior-posterior shear forces within the IVDs at the levels L3/L4 and L4/L5 following LAM. Conclusion: Our findings showed that it was feasible to forecast lumbar spine kinematics after three distinct decompression methods, which might be helpful in future clinical applications.

Abstract
Ebolaviruses cause outbreaks of haemorrhagic fever in Central and West Africa. Some members of this genus such as Ebola virus (EBOV) are highly pathogenic, with case fatality rates of up to 90%, whereas others such as Reston virus (RESTV) are apathogenic for humans. Bombali virus (BOMV) is a novel ebolavirus for which complete genome sequences were recently found in free-tailed bats, although no infectious virus could be isolated. Its pathogenic potential for humans is unknown. To address this question, we first determined whether proteins encoded by the available BOMV sequence found in Chaerephon pumilus were functional in in vitro assays. The correction of an apparent sequencing error in the glycoprotein based on these data then allowed us to generate infectious BOMV using reverse genetics and characterize its infection of human cells. Furthermore, we used HLA-A2-transgenic, NOD-scid-IL-2γ receptor-knockout (NSG-A2) mice reconstituted with human haematopoiesis as a model to evaluate the pathogenicity of BOMV in vivo in a human-like immune environment. These data demonstrate that not only does BOMV show a slower growth rate than EBOV in vitro, but it also shows low pathogenicity in humanized mice, comparable to previous studies using RESTV. Taken together, these findings suggest a low pathogenic potential of BOMV for humans.

Abstract
BACKGROUND Within the Hymenoptera, bees are notable for their relationship with flowering plants, being almost entirely dependent on plant pollen and nectar. Though functionally herbivorous, as a result of their role as pollinators, bees have received comparatively little attention as models for insect herbivory. Bees often display dietary specialization, but quantitative comparison against other herbivorous insects has not previously been conducted. RESULTS In the most comprehensive analysis to date for 860 bee species, dietary specialization amounted to 50.1% of studied species collecting pollen from between 1 and 2 botanical families with a relatively long tail of dietary generalists, with 11.1% of species collecting from more than 10 botanical families. This distribution deviated from the truncated Pareto distribution of dietary breadth seen in other herbivorous insect lineages. However, this deviation was predominantly due to eusocial bee lineages, which show a range of dietary breadths that conformed to a normal distribution, while solitary bees show a typical truncated distribution not strongly different from other herbivorous insects. We hypothesize that the relatively low level of dietary specialization in bees as a whole reflects the relaxation of the constraints typically observed in herbivorous insects with a comparatively reduced importance of plant chemistry and comparatively increased importance of phenology and foraging efficiency. The long flight periods of eusocial bees that are necessary to allow overlapping generations both allows and necessitates the use of multiple flowering resources, whereas solitary bees with short flight periods have more limited access to varied resources within a constrained activity period. CONCLUSIONS Collectively, solitary bees show slightly lower specialization compared to other herbivorous insects, possibly due to their balanced relationship with plants, rather than direct antagonism such as seen in the direct consumption of plant tissues. An additional factor may be the mediocre diversity of bees at low latitudes combined with low levels of dietary specialization, whereas these areas typically display a high rate of specialization by herbivorous insects in general. Though the most important factors structuring dietary specialization in bees appear to differ from many other herbivorous insects, solitary bees show a surprisingly similar overall pattern of dietary specialization.

Abstract
Giardia lamblia is a common parasitic protist that infects the small intestine and causes giardiasis, resulting in diarrhea, vomiting, weight loss, and malabsorption. Giardiasis leads to cellular damage, including loss of microvilli, disruption of tight junctions, impaired barrier function, enzyme inhibition, malabsorption, and apoptosis. In the host, motile Giardia trophozoites attach to the duodenal microvilli using a unique microtubule organelle called the ventral disc. Despite early observations of disc-shaped depressions in microvilli after parasite detachment, little is known about disc-mediated attachment mechanisms and there little direct evidence showing that parasite attachment causes cellular damage. However, advancements in in vitro organoid models of infection and genetic tools have opened new possibilities for studying molecular mechanisms of attachment and the impact of attachment on the host. Through high-resolution live imaging and a novel disc mutant, we provide direct evidence for disc contraction during attachment, resolving the long-standing controversy of its existence. Specifically, we identify three types of disc movements that characterize contraction, which in combination result in a decrease in disc diameter and volume. Additionally, we investigate the consequences of attachment and disc contractility using an attachment mutant that has abnormal disc architecture. In a human organoid model, we demonstrate that this mutant has a limited ability to break down the epithelial barrier as compared to wild type. Based on this direct evidence, we propose a model of attachment that incorporates disc contraction to generates the forces required for the observed "grasping" of trophozoites on the host epithelium. Overall, this work highlights the importance of disc contractility in establishing and maintaining parasite attachment, leading to intestinal barrier breakdown.

Abstract
Background and aims Compulsive buying-shopping disorder (CBSD) is mentioned as an example of other specified impulse control disorders in the ICD-11 coding tool, highlighting its clinical relevance and need for treatment. The aim of the present work was to provide a systematic update on treatment studies for CBSD, with a particular focus on online CBSD. Method The preregistered systematic review (PROSPERO, CRD42021257379) was performed in accordance with the PRISMA 2020 statement. A literature search was conducted using the PubMed, Scopus, Web of Science and PsycInfo databases. Original research published between January 2000 and December 2022 was included. Risk of reporting bias was evaluated with the CONSORT guideline for randomized controlled trials. Effect sizes for primary CBSD outcomes were calculated. Results Thirteen studies were included (psychotherapy: 2 open, 4 waitlist control design; medication: 2 open, 3 placebo-controlled, 2 open-label phase followed by a double-blind discontinuation phase; participants treatment/control 349/149). None of the studies addressed online CBSD. Psychotherapy studies suggest that group cognitive-behavioral therapy is effective in reducing CBSD symptoms. Pharmacological studies with selective serotonin re-uptake inhibitors or topiramate did not indicate superiority over placebo. Predictors of treatment outcome were rarely examined, mechanisms of change were not studied at all. Risk of reporting bias was high in most studies. Discussion Poor methodological and low quality of reporting of included studies reduce the reliability of conclusions. There is a lack of studies targeting online CBSD. More high-quality treatment research is needed with more emphasis on the CBSD subtype and mechanisms of change.

Abstract
In Lyme borreliosis, the skin constitutes a major interface for the host, the bacteria and the tick. Skin immunity is provided by specialized immune cells but also by the resident cells: the keratinocytes and the fibroblasts. Discoveries on the role of the microbiome in the modulation of skin inflammation and immunity have reinforced the potential importance of the skin in vector-borne diseases. In this study, we analyzed in vitro the interaction of human primary keratinocytes and fibroblasts with Borrelia burgdorferi sensu stricto N40 in presence or absence of bacterial commensal supernatants. We aimed to highlight the role of resident skin cells and skin microbiome on the inflammation induced by B. burgdorferi s.s.. The secretomes of Staphylococcus epidermidis, Corynebacterium striatum and Cutibacterium acnes showed an overall increase in the expression of IL-8, CXCL1, MCP-1 and SOD-2 by fibroblasts, and of IL-8, CXCL1, MCP-1 and hBD-2 in the undifferentiated keratinocytes. Commensal bacteria showed a repressive effect on the expression of IL-8, CXCL1 and MCP-1 by differentiated keratinocytes. Besides the inflammatory effect observed in the presence of Borrelia on all cell types, the cutaneous microbiome appears to promote a rapid innate response of resident skin cells during the onset of Borrelia infection.

Abstract
BACKGROUND Studies in convenience, non-clinical samples of young adults suggest overlap between online compulsive buying-shopping disorder (OCBSD) and social-networks-use disorder (SNUD). Considering the dearth of research, this study investigated OCBSD and SNUD in clinical samples. METHODS Women with either OCBSD (n = 37) or SNUD (n = 41) were compared regarding sociodemographic variables, use time of the first-choice application, OCBSD/SNUD severity, general internet use, impulsivity, materialism, perceived chronic stress and the frequency of viewing posts of influencers and the urge to visit shopping websites or social networks after viewing influencer posts. RESULTS Women in the OCBSD group were older, more often employed, had less often a qualification for university entrance, indicated a lower daily use time of the first-choice application and higher materialistic values as compared to those in the SNUD group. No group differences emerged regarding general internet use, impulsivity and chronic stress. Regression models indicate that chronic stress predicted the symptom severity in the SNUD but not in the OCBSD group. The SNUD group reported a higher frequency of viewing influencer posts as compared to the OCBSD group. The urge for online shopping or using social networks after viewing influencer posts did not significantly differ between both groups. CONCLUSION The findings suggest commonalities and distinct features of OCBSD and SNUD which require further investigation.

Abstract
BACKGROUND In pediatric intensive care, prescription, administration, and interpretation of drug doses are weight dependent. The use of standardized concentrations simplifies the preparation of drugs and increases safety. For safe administration as well as easy interpretation of intravenous drug dosing regimens with standardized concentrations, the display of weight-related dose rates on the infusion device is of pivotal significance. OBJECTIVES We report on challenges in the implementation of a new information technology-supported medication workflow. The workflow was introduced on eight beds in the pediatric heart surgery intensive care unit as well as in the pediatric anesthesia at the University of Bonn Medical Center. The proposed workflow utilizes medication labels generated from prescription data from the electronic health record. The generated labels include a two-dimensional barcode to transfer data to the infusion devices. METHODS Clinical and technical processes were agilely developed. The reliability of the system under real-life conditions was monitored. User satisfaction and potential for improvement were assessed. In addition, a structured survey among the nursing staff was performed. The questionnaire addressed usability as well as the end-users' perception of the effects on patient safety. RESULTS The workflow has been applied 44,111 times during the pilot phase. A total of 114 known failures in the technical infrastructure were observed. The survey showed good ratings for usability and safety (median "school grade" 2 or B for patient safety, intelligibility, patient identification, and handling). The medical management of the involved acute care facilities rated the process as clearly beneficial regarding patient safety, suggesting a rollout to all pediatric intensive care areas. CONCLUSION A medical information technology-supported medication workflow can increase user satisfaction and patient safety as perceived by the clinical end-users in pediatric acute care. The successful implementation benefits from an interdisciplinary team, active investigation of possible associated risks, and technical redundancy.

Abstract
Abstract
Purpose of the Review
To provide a systematic review of experimental studies concerning cognitive functions in compulsive buying-shopping disorder (CBSD) and to evaluate the studies as supporting or not supporting the affective and cognitive interactions proposed by the Interaction of Person-Affect-Cognition-Execution (I-PACE) model for addictive behaviors.
Recent Findings
The results of the present review concerning CBSD mirror findings regarding cue reactivity and disadvantageous decision making in other addictive behaviors, but they also demonstrate a relative lack of experimental studies addressing other cognitive domains such as attentional bias, inhibitory control, implicit associations, or Pavlovian-to-instrumental transfer. Experimental work on physiological and neural correlates of affective and cognitive mechanisms and their interaction in CBSD is still at the beginning.
Summary
While a reasonable number of experimental neuropsychological studies support the application of the I-PACE framework to CBSD, future research is required to systematically examine affective and cognitive interactions in CBSD.

Abstract
Deep-renovations measures are identified as possible solutions to support European Union's natural gas phase-out and fuel independency. However, it has been difficult to increase renovation rates (about 1% per year), and previous studies have recognized socio-economic barriers as one of the reasons for that. Then, integrated (techno-socio-economic) datasets are vital to support building policy measures that circumvent the negative consequences of high gas prices. This paper's main objective is to develop and to test a methodology that merges two data sources: the European Union Statistics on Income and Living Conditions and the Household Budget Survey in order to create an integrated techno-socio-economic dataset. The following research questions are answered: What is the replicable methodology for merging both datasets in order to create an accurate statistical model? What can we learn about household savings and natural gas expenditures of household types characterised by ownership status and dwelling type? The modelling results show that the developed logistic regression model presented an accuracy of 77% using 2015 data from Spain. The explorative statistical analysis showed that the owner-occupied single-family houses predominate in the highest natural gas expenditure quintiles, while the rented single-family houses in the lowest quintiles, indicating that ownership status may have a stronger influence on the natural gas expenditure than building type. The mean annual household savings are negative, an evidence of households' budget restrictions to finance deep renovation activities. As a conclusion, the generated techno-socio-economic synthetic dataset provides useful information about the relation between household budget restrictions, natural gas expenditure and potential investment on deep renovation. Based on the generated dataset, it is also concluded that higher natural gas prices alone are not sufficient to stimulate deep renovations. For boosting renovation activities, the design of financing and incentive schemes should be end-user targeted considering the households' heterogeneity. Then, the definition of households' profiles should include ownership status and other socio-economic parameters not only dwelling type. This work prepares the ground for setting techno-socio-economic databases that can be used to design more accurate incentives and financing schemes to accelerate European building stock decarbonisation and fossil fuel independency.

Abstract
Carbon 1s core-hole excitation of the molecular anion C2 - has been experimentally studied at high resolution by employing the photon-ion merged-beams technique at a synchrotron light source. The experimental cross section for photo-double-detachment shows a pronounced vibrational structure associated with 1 σ u → 3 σ g ${1\sigma _u \to 3\sigma _g }$ and 1 σ g → 1 π u ${1\sigma _g \to 1\pi _u }$ core excitations of the C2 - ground level and first excited level, respectively. A detailed Franck-Condon analysis reveals a strong contraction of the C2 - molecular anion by 0.2 Å upon this core photoexcitation. The associated change of the molecule's moment of inertia leads to a noticeable rotational broadening of the observed vibrational spectral features. This broadening is accounted for in the present analysis which provides the spectroscopic parameters of the C2 - 1 σ u - 1 3 σ g 2 2 Σ u + ${1\sigma _u^{ - 1} \,3\sigma _g^2 \;^2 \Sigma _u^ + }$ and 1 σ g - 1 3 σ g 2 2 Σ g + ${1\sigma _g^{ - 1} \,3\sigma _g^2 \;^2 \Sigma _g^ + }$ core-excited levels.

Abstract
We have added a multipole ion trap to the existing photon-ion spectrometer at PETRA III (PIPE). Its hybrid structure combines a ring-electrode trap with a segmented 16-pole trap. The interaction of gases and ions with extreme ultraviolet radiation from the beamline P04 is planned to be investigated with the newly installed multipole trap. The research focus lies on radiation-induced chemical reactions that take place in the interstellar medium or in the atmospheres of planets, including natural as well as man-made processes that are important in the Earth's atmosphere. In order to determine the mass-to-charge ratio of the stored ions as efficiently as possible, we are using an ion time-of-flight spectrometer. With this technique, all stored ions can be detected simultaneously. To demonstrate the possibilities of the trap setup, two experiments have been carried out: The photoionization of xenon and the ion-impact ionization of norbornadiene. This type of ion-impact ionization can, in principle, also take place in planetary atmospheres. In addition to ionization by photon or ion impact, chemical reactions of the trapped ions with neutral atoms or molecules in the gas phase have been observed. The operation of the trap enables us to simulate conditions similar to those in the ionosphere.

Abstract
Diagnostic criteria for compulsive buying shopping disorder were recently proposed based on a Delphi consensus study including 138 experts from 35 countries. The present study represents a secondary analysis of those data. To provide further support for the validity of expert responses in the Delphi study, the sample was retrospectively divided into clinician and researcher subgroups. The two groups were compared with respect to demographic variables, their importance ratings of clinical features, possible diagnostic criteria, differential diagnoses and specifiers of compulsive buying shopping disorder. Researchers reported less years of treating/assessing individuals with compulsive buying shopping disorder and stated that they have treated/assessed individuals with compulsive buying shopping disorder less often in the last 12 months than clinicians. Responses from the two groups concerning the importance ratings of possible diagnostic criteria of compulsive buying shopping disorder converged with only few minor differences with small to moderate group effects. However, even for those criteria, the consensus threshold (≥75% agreement with the proposed criterion) was reached in both groups. The lack of differences in the responses of the two groups indicates good validity for the proposed diagnostic criteria. Future research should address the clinical applicability and diagnostic validity of the criteria.

Abstract
INTRODUCTION Traumatic shoulder instability most frequently occurs in young people often during sports events. Currently, the arthroscopic Bankart repair is the therapy of choice in the absence of extensive glenoid bone loss and has proved to be a safe and effective procedure. Nevertheless, we see recurrence of instability-especially if new trauma happens-and further data are needed to guide the right decision-making for these often young patients. The purpose of this study was to determine the long-term outcome 10 years after arthroscopic Bankart operation in terms of satisfaction of the patient, functional result, complications, recurrent instability, and development of osteoarthritis, and to look after possible risk factors for recurrence of instability and statistical proof of these. MATERIALS AND METHODS Thirty-nine out of 49 patients underwent physical examination of both shoulders. We could perform a postoperative shoulder a-p X-ray in 28 patients. According to Samilson, [24] the extent of osteoarthritis was measured. The Constant score and the postoperative ROWE score were determined for both shoulders as well as the WOSI Score. In 25 cases, we calculated the ISIS Score. RESULTS We could reach out to 89.6% of patients and 79.6% could be physically examined. The vast majority of 95.5% are either very satisfied or satisfied with the result at the time we ended the follow-up. The mean Constant score of 95.5 reflects this result. In contrast to this, we found at the same time in 15.3% ongoing clinical signs of instability of the concerning shoulder, even though 9.1% had to be re-operated for recurrent instability in between the follow-up timeline and we found in the X-rays (57.1% of all patients) in 35.7% at least moderate and in 10.7% severe signs of osteoarthritis. The Constant score but not the ROWE score differed significantly in patients with no or mild compared to those with moderate-to-severe osteoarthritis. CONCLUSIONS The arthroscopic Bankart stabilization procedure showed after 10 years to be a very safe operation and to be able to produce a satisfying and functional very good long-term result-reflected by the Constant score. We assume that the extent of osteoarthritis seems to be the determining factor of the very good functional result, even though ongoing instability was present in 15.3% of the patients.

Abstract
Global concern about problematic usage of the internet (PUI), and its public health and societal costs, continues to grow, sharpened in focus under the privations of the COVID-19 pandemic. This narrative review reports the expert opinions of members of the largest international network of researchers on PUI in the framework of the European Cooperation in Science and Technology (COST) Action (CA 16207), on the scientific progress made and the critical knowledge gaps remaining to be filled as the term of the Action reaches its conclusion. A key advance has been achieving consensus on the clinical definition of various forms of PUI. Based on the overarching public health principles of protecting individuals and the public from harm and promoting the highest attainable standard of health, the World Health Organisation has introduced several new structured diagnoses into the ICD-11, including gambling disorder, gaming disorder, compulsive sexual behaviour disorder, and other unspecified or specified disorders due to addictive behaviours, alongside naming online activity as a diagnostic specifier. These definitions provide for the first time a sound platform for developing systematic networked research into various forms of PUI at global scale. Progress has also been made in areas such as refining and simplifying some of the available assessment instruments, clarifying the underpinning brain-based and social determinants, and building more empirically based etiological models, as a basis for therapeutic intervention, alongside public engagement initiatives. However, important gaps in our knowledge remain to be tackled. Principal among these include a better understanding of the course and evolution of the PUI-related problems, across different age groups, genders and other specific vulnerable groups, reliable methods for early identification of individuals at risk (before PUI becomes disordered), efficacious preventative and therapeutic interventions and ethical health and social policy changes that adequately safeguard human digital rights. The paper concludes with recommendations for achievable research goals, based on longitudinal analysis of a large multinational cohort co-designed with public stakeholders.

Abstract
OBJECTIVE Although medication adherence (MA) contributes to therapeutic outcome in systemic sclerosis (SSc), research data are scarce. Factors influencing MA in SSc are hardly known. METHOD We conducted a monocentric, cross-sectional study on 85 patients with SSc at the University of Lübeck, Germany, using the Compliance Questionnaire of Rheumatology as the main measurement tool of MA. We also used the Scleroderma Health Assessment Questionnaire, Illness Perception Questionnaire - Revised, Health Literacy Questionnaire, Lübeck Medication Satisfaction Questionnaire (a novel instrument created for this study), and patients' demographic and clinical data, to find factors contributing to MA. RESULTS Good MA was seen in 51.8% of patients. MA was positively associated with therapy satisfaction (p < 0.001), modified Rodnan Skin Score (p = 0.032), age (p = 0.025), intake of micronutrients (p = 0.033), number of prescribed drugs (p = 0.014), and some dimensions of health literacy. Negative associations were found for patients with weight loss attributed to SSc (p = 0.009) and the perception that the disease is caused by the patient's personality (p = 0.011) or emotional state (p = 0.037). CONCLUSION Although most SSc patients display good MA, non-adherence remains a major problem. Patients should be assessed for non-adherence. The factors affecting MA identified herein could help to improve therapeutic outcomes.

Abstract
Background Deficits in inhibitory control seem to promote habit behavior and therefore play an important role in the development and maintenance of addictive diseases. Although several training approaches have been suggested, there is a considerable lack of knowledge about the best way to improve inhibitory control. Based on a literature review regarding shortcomings of existing trainings, an individualized, adaptive inhibitory control training was developed. We aimed to assess feasibility and acceptance of this training and to provide preliminary results on its efficacy regarding inhibitory control and binge drinking. Methods Sixty-one individuals (30 female) with binge drinking behavior were randomly allocated to either an experimental group receiving three sessions of the inhibitory control training or a waitlist control group receiving no training. Before and after the training, the participants performed a Go/NoGo task to assess inhibitory control (commission errors and false reaction time), completed a questionnaire on drinking-related self-control, and reported drinking behavior. Results Although the training was feasible and accepted by participants, it did not affect self-control over drinking, inhibitory control or drinking behavior. The relationship between session number and false reaction time was linear for alcohol stimuli, but squared for neutral stimuli. Conclusion Although our findings have to be interpreted in the light of some shortcomings, they demonstrate that further research is needed to enhance our understanding of how to improve inhibitory control and which factors might moderate this process.

Abstract
Motherhood has been proposed as an internal facilitating factor for the recovery of women with mental disorders. However, at the same time, there are significant barriers that may be interfering with the access and adherence to treatment for these women. The present longitudinal study aimed to deepen the sociodemographic and clinical profile of women with children and compulsive buying–shopping disorder (CBSD), and to explore the association between motherhood and response to treatment. The total sample included 77 women with a diagnosis of CBSD (n = 49 mothers) who received cognitive behavioral therapy (CBT) for 12 weeks. No association between psychopathology and motherhood was observed. The group of mothers reported an older age of onset of the CBSD, a lower amount of money spent per compulsive-buying episode, and a higher likelihood of family support for the CBSD. Moreover, this group showed lower risk of relapse. The findings support the theoretical proposal that considers motherhood as an internal facilitating factor for recovery and treatment adherence of mothers with addictions.

BackgroundIn SSc, autoantibodies (abs) directed against G protein-coupled receptors (GPCR) are prominent and for example induce release of inflammatory and profibrotic proteins by monocytes (1-3). Increased levels of autoantibodies against angiotensin II type 1 receptor (AT1R abs) have been found in patients with renal involvement in systemic sclerosis (SSc) (4-5). The elevated amount of anti-GPCR abs is accompanied by increased secretion of extracellular vesicles (EVs) in SSc (6). The importance of EVs in the pathogenesis is also based on packing and horizontal transfer of AT1R to different tissues and immune cells, exemplary shown by activated cardiomyocytes leading to higher responsiveness to Angiotensin II of recipient cells and vessels (7). Taken together, the relevance of studying anti-GPCR abs together with GPCR-EVs in SSc pathogenesis becomes evident (8). Interestingly, CCL18 is found to be upregulated in SSc patients and suggested to be upregulated by AT1R abs (9), indicating CCL18 and CCR8 cross-talk via EVs plays an essential role in the pathogenesis of SSc.ObjectivesUnravel the immune response of peripheral blood monocytes mediated by anti-AT1R abs and EVs to gain new insights into the pathomechanism in SSc.MethodsHuman peripheral blood monocytes of healthy donors were stimulated by the endogenous AT1R ligand angiotensin II as well as by a monoclonal anti-human AT1R ab and, in comparison, by purified IgG from HD (HD IgG) versus those from SSc (SSc IgG). Further, human peripheral blood monocytes of HD were treated with EVs derived from sera of SSc patients versus sera of HD, in the presence or absence of a monoclonal recombinant anti-AT1R ab. Monoclonal AT1R ab has been generated by hybridoma technique, sequenced and recombinantly expressed in HEK cells. The specificity of AT1R abs was tested by using an AT1R blocker (telmisartan, TEL). EVs were isolated from sera by differential centrifugation to exclude large particles and microvesicles and further by one-step polymer precipitation procedure utilising ExoQuick Exosome Precipitation Solution (System Biosciences, Palo Alto, CA) and subsequent purification by size exclusion. Further, primary human peripheral blood monocytes of HD (n=6) were treated with EVs derived from sera of SSc patients (n=6) versus sera of HD (n=6), in the presence or absence of a monoclonal recombinant anti-AT1R ab. The response of the monocytes was measured via CCL18 secretion by ELISA.ResultsThe recombinant monoclonal anti-human AT1R antibody induced secretion of CCL18, a profibrotic cytokine, by primary monocytes derived from HD. Similarly, the purified IgG fractions derived from SSc patients also induced an increased CCL18 release by monocytes compared to IgG fractions derived from HD. Further, complete amelioration of the AT1R ab effect on CCL18 secretion was found, when monocytic AT1R expression was blocked with TEL. In addition, antagonistic effects of Angiotensin II to the monoclonal AT1R ab were observed. In line, enhanced CCL18 secretion of human monocytes stimulated with SSc-EVs alone and together with the monoclonal AT1R ab was induced.ConclusionThe secretion of pro-fibrotic CCL18 by human monocytes in response to a monoclonal AT1R antibody as well as to SSc IgG indicates that anti-AT1R abs are involved in the SSc pathogenesis. Further, this effect could also be due to SSc-EVs potentially presenting anti-GPCR abs to their receptors on immune cells.References[1]Cabral-Marques O, et al.

Abstract
BackgroundA defect in regulatory T cell (Treg) homeostasis due to an acquired deficiency of interleukin-2 (IL-2) plays an important role in the pathogenesis of systemic lupus erythematosus (SLE).1,2 However, it is still unclear whether a defect in the Treg-IL-2 axis is also involved in other connective tissue disease such as inflammatory myopathies or primary Sjogren´s syndrome (pSS).ObjectivesThe aim of our study was to investigate whether Treg from patients with poly- and dermatomyositis (PM/DM) and pSS display typical features of IL-2 deficiency in parallel to phenotypic alterations of conventional CD4+ T cell (Tcon) subsets compared to healthy controls (HC).MethodsPBMC were isolated from patients with PM/DM (n=22) and pSS (n=17) and from age- and sex-matched HC (n=19) using gradient density centrifugation. Treg and Tcon subsets were analyzed by using multicolor flow cytometry. Mann-Whitney test was used for statistical analyses.ResultsFrequencies of FoxP3+CD127lo Treg among CD3+CD4+T cells were higher in pSS compared to PM/DM patients (p<0.001) and to HC (p<0.05). However, in both, PM/DM and pSS patients, frequencies of CD25+ cells among FoxP3+CD127lo Treg were significantly lower compared to HC (PM/DM: p<0.05, pSS: p<0.0001), while the frequencies of Helios+ cells among the CD25- Treg subset were substantially higher in pSS patients compared to DM/PM and HC (both p<0.001). Conversely, we found lower frequencies of CXCR5+ follicular Treg only in PM/DM patients (p<0.05). In parallel, there were higher frequencies of CD45RO+CCR7- effector/memory cells (p<0.01) and of Ki67+ proliferating cells (p<0.05) among CD3+CD4+FoxP3- Tcon in pSS patients compared to HC, which was not observed in PM/DM patients.ConclusionThe loss of the CD25+ Treg subset in PM/DM and pSS patients is similar to previous findings in SLE patients1 and represents a hallmark of IL-2 deficiency. This suggests that shortage of IL-2 is pathophysiologically relevant also in PM/DM and pSS providing a rationale for low-dose IL-2 therapy in these diseases. In addition, activation and expansion of effector/memory Tcon appears to be more pronounced in pSS compared to PM/DM. The different distribution of Treg and of Tcon subsets between pSS and PM/DM patients might reflect differences in the availability of IL-2 and in the regulation of Tcon responses in these diseases.References[1]von Spee-Mayer C, Siegert E, Abdirama D, et al.

Abstract
BackgroundAntibodies directed to the angiotensin receptor type 1 (AT1R) were found to be increased in patients with SSc ad they predict mortality and SSc complications (1, 2). In vitro studies suggested an involvement in the pathogenesis of systemic sclerosis (SSc).ObjectivesHere, we aim to determine the contribution and functions of AT1R autoantibodies (Abs) in vivo and in vitro as well as their capacity to recognize AT1R from different species.MethodsC57BL/6J mice were immunized with membrane-embedded human AT1R or empty membrane as control. Phenotypic properties of various organs were examined by immunohistochemistry, immunofluorescence, and TUNEL apoptosis assay. A monoclonal (m)AT1R Ab was generated based upon this mouse model by hybridoma technology and transferred into C57BL/6J mice. Mice deficient for CD4+ and CD8+ T cells, B cells and AT1Ra/b served as controls. In vitro, Abs responses towards AT1R were measured using rat cardiomyocytes, human epithelial cells, AT1R-transfected HEK293 cells and primary human monocytes.ResultsAT1R-immunized mice developed perivascular skin and lung inflammation, lymphocytic alveolitis, weak endothelial apoptosis and skin fibrosis, not present in controls or mice deficient for CD4+ T and B cells. The contribution of AT1R Abs to skin manifestations and interstitial lung disease was demonstrated by application of a mAT1R Ab, which induced skin and lung inflammation, not observed in the AT1Ra/b knockout mice. IgG from immunized mice containing AT1R Abs and/or the mAT1R Ab activated rat cardiomyocytes and human monocytes. Treatment of AT1R-transfected HEK293 cells with the mAT1R Ab enhanced AT1R signaling in the presence of the endogenous agonist Angiotensin II.ConclusionOur immunization strategy successfully induced AT1R Abs, contributing to inflammation and most likely to fibrosis via activation of AT1R. Therefore, AT1R Abs are valuable targets for future therapies in SSc and possibly other AT1R Ab-related diseases.References[1]Riemekasten, G. et al.

Abstract
BackgroundSystemic sclerosis (SSc) is characterized by chronic inflammation that leads to damage of the vascular endothelium and excessive collagen deposition in several target organs (1). The interaction of interleukin 2 (IL-2) with the corresponding receptor (IL-2R) is involved in the regulation of autoimmune processes (2). The shedding product of the IL-2R alpha chain, soluble IL-2 receptor (sIL-2R, CD25), is able to either reduce or enhance immune responses (2). Previously, elevated serum levels of sIL-2R were found in the bronchoalveolar lavage of SSc patients with interstitial lung disease (SSc-ILD) as well as serologically in patients with early SSc, and thus suggested to be a biomarker for clinical development of SSc (3,4).ObjectivesTo examine concentrations of sIL-2 in patients with SSc and analyse their association with clinical and serological parameters.MethodsTo determine if serological levels of sIL-2R serve as predictor of clinical complications in SSc, sera were analysed [limited cutaneous SSc (lcSSc) n=160; diffuse cutaneous SSc (dSSc), n=137] using a sandwich ELISA. Clinical data (pulmonary fibrosis, PAH, mRSS, therapy) and serological markers (hs-CRP, NT-pro BNP, neutrophil counts, creatinine, hs-troponin T, creatinine kinase, beta2-microglobuline) were assessed at the time of serum sampling and up to 48 months after baseline. Clinical progress was defined by the need to change therapies.ResultsPatients with dSSc presented elevated levels of sIL-2R compared to SSc (dSSc: 673±428 U/ml vs. 646±473 U/ml, p=0.0001). In SSc general, sIL-2R levels correlated with beta2-microglobuline (r=0.6161, p<0.0001, ROC-AUC:0.8428), hs-CRP (r=0.4091, p<0.0001, ROC-AUC:0.7110), NT-proBNP (r=0.2610, p<0.0001, ROC-AUC:0.6793), neutrophil count (r=0.2749, p<0.0001) and hs-troponin T (r=0.4548, p<0.0001, ROC-AUC:0.8729). Further, sIL-2R levels discriminated normal from pathological levels of hs-troponin T (sensitivity 80.0%, specificity 80.1%). Using Log-rank test and Mantel-Cox proportional hazard models, we found that sIL-2R levels above 745.5 U/ml predicted early clinical progress in SSc (HR: 3.45, p=0.0070, Figure 1) within 12 months.Figure 1.Kaplan-Meier survival analysis for the complete group of patients with SSc. Soluble Il-2R levels above 745U/ml were associated with early progress in SSc.ConclusionIn SSc, serum levels of sIL-2R could be of diagnostic value by identifying clinical progress. Its role in pathophysiology, especially with regard to disease manifestations such as cardiac involvement needs to be investigated in more detail.References[1]Blagojevic J et al.

Abstract
Magnetic resonance (MR) diffusion-weighted imaging (DWI) is often used to detect focal liver lesions (FLLs), though DWI image quality can be limited in the left liver lobe owing to the pulsatile motion of the nearby heart. Flow-compensated (FloCo) diffusion encoding has been shown to reduce this pulsation artifact. The purpose of this prospective study was to intra-individually compare DWI of the liver acquired with conventional monopolar and FloCo diffusion encoding for assessing metastatic FLLs in non-cirrhotic patients. Forty patients with known or suspected multiple metastatic FLLs were included and measured at 1.5 T field strength with a conventional (monopolar) and a FloCo diffusion encoding EPI sequence (single refocused; b-values, 50 and 800 s/mm2). Two board-certified radiologists analyzed the DWI images independently. They issued Likert-scale ratings (1 = worst, 5 = best) for pulsation artifact severity and counted the difference of lesions visible at b = 800 s/mm² separately for small and large FLLs (i.e., < 1 cm or > 1 cm) and separately for left and right liver lobe. Differences between the two diffusion encodings were assessed with the Wilcoxon signed-rank test. Both readers found a reduction in pulsation artifact in the liver with FloCo encoding (p < 0.001 for both liver lobes). More small lesions were detected with FloCo diffusion encoding in both liver lobes (left lobe: six and seven additional lesions by readers 1 and 2, respectively; right lobe: five and seven additional lesions for readers 1 and 2, respectively). Both readers found one additional large lesion in the left liver lobe. Thus, flow-compensated diffusion encoding appears more effective than monopolar diffusion encoding for the detection of liver metastases.

Abstract
Background and aims With the inclusion of gaming disorder in the ICD-11, diagnostic criteria were introduced for this relatively new disorder. These criteria may also be applied to other potential specific Internet-use disorders, which may be classified in ICD-11 as other disorders due to addictive behaviors, such as online buying-shopping disorder, online pornography-use disorder, social-networks-use disorder, and online gambling disorder. Due to the heterogeneity in existing instruments, we aimed to develop a consistent and economic measure of major types of (potential) specific Internet-use disorders based on ICD-11 criteria for gaming disorder. Methods The new 11-item Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) measures five behavioral addictions with the same set of items by following the principles of WHO's ASSIST. The ACSID-11 was administered to active Internet users (N = 985) together with an adaptation of the Ten-Item Internet Gaming Disorder Test (IGDT-10) and screeners for mental health. We used Confirmatory Factor Analyses to analyze the factor structure of ACSID-11. Results The assumed four-factorial structure was confirmed and was superior to the unidimensional solution. This applied to gaming disorder and to the other specific Internet-use disorders. ACSID-11 scores correlated with IGDT-10 as well as with the measures of psychological distress. Discussion and Conclusions The ACSID-11 seems to be suitable for the consistent assessment of (potential) specific Internet-use disorders based on ICD-11 diagnostic criteria for gaming disorder. The ACSID-11 may be a useful and economic instrument for studying various behavioral addictions with the same items and improving comparability.

Abstract
BACKGROUND Compulsive buying-shopping disorder (CBSD) is associated with high materialistic values endorsement and excessive purchasing of consumer goods. A subgroup of individuals with CBSD engage in socially unacceptable behaviors to continue shopping despite negative consequences. This investigation aimed at exploring possible links between ego-oriented shopping-related decisions, materialism, symptoms of CBSD and close-to-everyday moral decision making. METHODS In study 1, patients with CBSD were interviewed to develop a list of conflict situations, capturing typical shopping-related dilemmas. In study 2, the shopping-related dilemmas from study 1, standardized close-to-everyday moral dilemmas, the Material Values Scale and Pathological Buying Screener were administered to a web-based convenience sample (n = 274). RESULTS The main effects of a moderated hierarchical regression analysis revealed an association of more ego-oriented shopping-related decisions with both higher materialistic values endorsement and more CBSD symptoms, but not with everyday moral decision-making. However, a more egoistic everyday moral decision making style moderated the effect of CBSD symptoms on ego-oriented shopping related decisions. CONCLUSIONS The findings indicate that a more egoistic everyday moral decision making style is not directly linked to domain-specific shopping-related decision making but strengthens the link between symptoms of CBSD and ego-oriented shopping-related decisions.

Abstract
INTRODUCTION Misophonia refers to a phenomenon in which affected individuals have a selective intolerance to sounds of mostly oral or nasal origin. This intolerance is typically associated with strong emotional reactions such as anger, irritation, and disgust. The aim of this study was to conduct the first large epidemiological survey to determine the prevalence of misophonia symptoms in the adult population in Germany. METHODS We conducted a large-scale representative population survey between December 2020 and March 2021. For this purpose, a sample of 2,519 people were visited in their households and assessed with the Misophonia Questionnaire (MQ) and the Amsterdam Misophonia Questionnaire (AMISOS-R) to document misophonic symptoms. The primary estimate of clinical misophonia symptoms prevalence was based on the MQ Severity Scale and a secondary estimate was based on the AMISOS-R. The survey further included self-ratings to measure perfectionism, not-just-right experience (NJRE), autonomous sensory meridian response (ASMR) and general health as well as demographic data. RESULTS Five percent of the sample scored equal or above the MQ Severity Scale threshold for clinical misophonia symptoms (5.9% based on AMISOS-R). Individuals with clinical misophonia symptoms had a higher rate of perfectionism, a higher occurrence of NJRE, higher susceptibility to ASMR, and a worse general health status than those scoring below the cut-off-score. All those factors also independently predicted the severity of misophonia symptoms in a multiple regression model. CONCLUSION Misophonia is a frequent condition and should further be examined as an independent diagnostic entity.

Abstract
OBJECTIVE It is commonly agreed, that Behavioral Addictions are accompanied by mental disorders and are still underdiagnosed. The multicenter cross-sectional study aimed at estimating the prevalence of Behavioral Addictions in a consecutive sample of patients seeking treatment for mental disorders other than Behavioral Addiction. METHODS The study included 801 patients from eight psychosomatic university hospitals. Behavioral Addictions were assessed via standardized questionnaires. RESULTS 24.1% of the sample reported at least one Behavioral Addiction. The majority of those patients reported symptoms of a single Behavioral Addiction. Questionnaire-based prevalence rates were 3.4% for Pathological Gambling, 1.9% for Pathological Internet Use, 16.7% for Pathological Buying, 5.4% for Hypersexual Disorder, and 3.5% for pathological exercising (exercise dependence). Neither center nor setting (outpatient, inpatient, day clinic) effects were observable. DISCUSSION Within this clinical sample, symptoms of shopping addiction are highly common in patients undergoing psychosomatic-psychotherapeutic treatment. These are rather women. Men are more likely to suffer from gambling and sex addiction. Generally, symptoms of Behavioral Addictions are commonly reported. Till today, Behavioral Addictions are often still underdiagnosed. CONCLUSION Patients within psychosomatic treatment commonly suffer from symptoms of Behavioral Addictions, which should be considered for treatment strategies.

Abstract
In the eleventh International Classification of Diseases (ICD-11) of the World Health Organization, gambling disorder and gaming disorder are included in the category 'disorders due to addictive behaviours', which can be specified further as occurring either predominantly offline or predominantly online. Other specific problematic behaviours may be considered for the category 'other specified disorders due to addictive behaviours'. The Research Unit FOR 2974, funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG), focuses on the most prominent online addictive behaviours: gaming, pornography use, buying-shopping and social-networks use. The main goal of the Research Unit is to contribute to a better understanding of the common and differential psychological as well as neurobiological mechanisms involved in these specific types of Internet-use disorders. We aim to investigate theoretically argued (bio)psychological processes with a focus on concepts coming from research of substance-use disorders, for example, cue reactivity and craving, executive functions and specific inhibitory control, coping, implicit cognitions, and decision making. One central characteristic of the Research Unit is that we will investigate all participants using a comprehensive core battery of experimental paradigms, neuropsychological tasks, questionnaires, biomarkers, ambulatory assessment, and a 6-month follow-up survey. Beyond the anticipated contributions to the scientific understanding of the mechanisms involved in the development and maintenance of respective online addictive behaviours, we also expect contributions to clinical practice by showing which affective and cognitive mechanisms may be addressed more intensively to optimize treatment.

Abstract
Next to d-glucose, the pentoses l-arabinose and d-xylose are the main monosaccharide components of plant cell wall polysaccharides and are therefore of major importance in biotechnological applications that use plant biomass as a substrate. Pentose catabolism is one of the best-studied pathways of primary metabolism of Aspergillus niger, and an initial outline of this pathway with individual enzymes covering each step of the pathway has been previously established. However, although growth on l-arabinose and/or d-xylose of most pentose catabolic pathway (PCP) single deletion mutants of A. niger has been shown to be negatively affected, it was not abolished, suggesting the involvement of additional enzymes. Detailed analysis of the single deletion mutants of the known A. niger PCP genes led to the identification of additional genes involved in the pathway. These results reveal a high level of complexity and redundancy in this pathway, emphasizing the need for a comprehensive understanding of metabolic pathways before entering metabolic engineering of such pathways for the generation of more efficient fungal cell factories.

Abstract
Abstract
Purpose of Review
Problematic online buying-shopping became a recent research topic, and the question arises as to whether it would be useful to differentiate between a “predominantly online” and a “predominantly offline” compulsive buying-shopping disorder (CBSD) subtype by analogy with gaming disorder and gambling disorder in the ICD-11. This narrative review aims at reflecting the discussions on overlaps of problematic online buying-shopping with both offline CBSD and specific internet-use disorders.
Recent Findings
Preliminary data suggest that problematic online buying-shopping shares many commonalities with both offline CBSD and potential specific internet-use disorders (e.g., gaming disorder, pornography-use disorder, or social-network–use disorder). However, there is a lack of research addressing the etiology, underlying affective and cognitive mechanisms, psychosocial correlates, comorbidity profiles, and treatment of problematic online buying-shopping.
Summary
The question of whether online CBSD can develop independently from offline CBSD or only as medial transformation of offline CBSD still remains unanswered due to limited research on problematic online buying-shopping. Both perspectives are conceivable: that online CBSD represents a standalone specific internet-use disorder or the online subtype of CBSD. Future studies should examine which approach has clinical utility and indicates specific treatment options and better outcomes.

Abstract
Abstract
BACKGROUND
The use of photodynamic agents in malignant cranial tumor surgery is quite common. For example five-aminolevulinic acid (5-ALA)-induced porphyrins in malignant gliomas are potent photosensitizers. Until today there is no comparable selective fluorescent substance available for meningiomas. Nevertheless, there is a demand for intraoperative fluorescent identification of e.g. invasive skull base meningiomas to increase radicality. This study was established to investigate fluorescent image-guided resection with somatostatin receptor labelled fluorescence dye for intracranial meningioma in the nude mice.
MATERIAL AND METHODS
Primary meningioma cell culture samples were stereotactically implanted subdural into 20 nude mice. 90 days after inoculation of the cells, a cranial MRI with contrast agent revealed tumor growth. After detection of tumor mass in MRI, FAM-TOC5,6-Carboxyfluoresceine-Tyr3-Octreotide was injected intravenously and tumor mass was hereafter resected under visualization via fluorescence microscope and endoscope. After attempted total resection, animal were sacrificed brain slices were obtained and histologically analysed to verify the resection extent.
RESULTS
In 18 mice tumor growth was detected in MRI after 90 days of inoculation. The tumor mass could be clearly identified with fluorescence microscope and endoscope after injecting FAM-TOC5,6-Carboxyfluoresceine-Tyr3-Octreotide. The tumor margins could be better visualized. After fluorescence-guided resection no remaining tumor could be identified in histological analysis.
CONCLUSION
This study describes for the first time the use of FAM-TOC5,6-Carboxyfluoresceine-Tyr3-Octreotide and demonstrates its value of fluorescent identification of meningioma cells in vivo. Furthermore, the authors established a new experimental animal model for fluorescence meningioma surgery.

Abstract
BACKGROUND AND AIMS Following the recognition of 'internet gaming disorder' (IGD) as a condition requiring further study by the DSM-5, 'gaming disorder' (GD) was officially included as a diagnostic entity by the World Health Organization (WHO) in the 11th revision of the International Classification of Diseases (ICD-11). However, the proposed diagnostic criteria for gaming disorder remain the subject of debate, and there has been no systematic attempt to integrate the views of different groups of experts. To achieve a more systematic agreement on this new disorder, this study employed the Delphi expert consensus method to obtain expert agreement on the diagnostic validity, clinical utility and prognostic value of the DSM-5 criteria and ICD-11 clinical guidelines for GD. METHODS A total of 29 international experts with clinical and/or research experience in GD completed three iterative rounds of a Delphi survey. Experts rated proposed criteria in progressive rounds until a pre-determined level of agreement was achieved. RESULTS For DSM-5 IGD criteria, there was an agreement both that a subset had high diagnostic validity, clinical utility and prognostic value and that some (e.g. tolerance, deception) had low diagnostic validity, clinical utility and prognostic value. Crucially, some DSM-5 criteria (e.g. escapism/mood regulation, tolerance) were regarded as incapable of distinguishing between problematic and non-problematic gaming. In contrast, ICD-11 diagnostic guidelines for GD (except for the criterion relating to diminished non-gaming interests) were judged as presenting high diagnostic validity, clinical utility and prognostic value. CONCLUSIONS This Delphi survey provides a foundation for identifying the most diagnostically valid and clinically useful criteria for GD. There was expert agreement that some DSM-5 criteria were not clinically relevant and may pathologize non-problematic patterns of gaming, whereas ICD-11 diagnostic guidelines are likely to diagnose GD adequately and avoid pathologizing.

Abstract
OBJECTIVE The aim of the present study was to investigate whether the remission of preoperative food addiction is associated with increases or new onset of other addictions within the first year following bariatric surgery. METHODS One hundred and twenty-five bariatric surgery patients were assessed before surgery (t1) and at 6 months (t2) and 1 year (t3) follow-ups. The assessments included the Yale Food Addiction Scale 2.0 (YFAS 2.0) and standardized questionnaires to measure symptoms of problematic alcohol use, gambling disorder, internet-use disorder, buying-shopping disorder, hypersexual disorder and exercise dependence. RESULTS Forty-nine (39.2%) patients were assigned to the food addiction (FA+ ) and 76 patients (60.8%) to the non-food addiction group (FA- ) based on their preoperative YFAS scores. Overall, BMI and symptoms of food addiction decreased significantly from baseline to follow-ups. Preoperative food addiction status was not associated with postoperative increases or new onset of other addictions. Elevated symptoms of buying-shopping disorder, internet-use and hypersexual behaviour at baseline in the FA+ -group decreased over time and were comparable to the FA- -group at follow-ups. CONCLUSION The 'addiction transfer' or 'cross addiction' hypothesis was not supportive for alcohol addiction, gambling addiction or other behaviours that may be addictive. Further studies are needed that investigate larger samples and longer observation periods, as well as other substance-use disorders.

Abstract
Prostate cancer (PCa) shows strong dependence on the androgen receptor (AR) pathway. Here, we show that squalene epoxidase (SQLE), an enzyme of the cholesterol biosynthesis pathway, is overexpressed in advanced PCa and its expression correlates with poor survival. SQLE expression is controlled by micro-RNA 205 (miR-205), which is significantly downregulated in advanced PCa. Restoration of miR-205 expression or competitive inhibition of SQLE led to inhibition of de novo cholesterol biosynthesis. Furthermore, SQLE was essential for proliferation of AR-positive PCa cell lines, including abiraterone or enzalutamide resistant derivatives, and blocked transactivation of the AR pathway. Inhibition of SQLE with the FDA approved antifungal drug terbinafine also efficiently blocked orthotopic tumour growth in mice. Finally, terbinafine reduced levels of prostate specific antigen (PSA) in three out of four late-stage PCa patients. These results highlight SQLE as a therapeutic target for the treatment of advanced PCa.

Abstract
Metallic implant biomaterials predominate in orthopaedic surgery. Compared to titanium-based permanent implants, magnesium-based ones offer new possibilities as they possess mechanical properties closer to the ones of bones and they are biodegradable. Furthermore, magnesium is more and more considered to be "bioactive" i.e., able to elicit a specific tissue response or to strengthen the intimate contact between the implant and the osseous tissue. Indeed, several studies demonstrated the overall beneficial effect of magnesium-based materials on bone tissue (in vivo and in vitro). Here, the direct effects of titanium and magnesium on osteoblasts were measured on proteomes levels in order to highlight metal-specific and relevant proteins. Out of 2100 identified proteins, only 10 and 81 differentially regulated proteins, compare to the control, were isolated for titanium and magnesium samples, respectively. Selected ones according to their relationship to bone tissue were further discussed. Most of them were involved in extracellular matrix maturation and remodelling (two having a negative effect on mineralisation). A fine-tuned balanced between osteoblast maturation, differentiation and viability was observed.

Abstract
Abstract
Study question
Does cryopreservation and transplantation of bovine ovarian medulla-containing cortex tissue improve the viability and vascularization of the graft? Summary answer: Transplantation of bovine ovarian cortex containing medulla has a positive effect on follicular viability and neovascularization of the graft compared to cortex transplantation alone.
What is known already
For female fertility protection, cryopreservation and retransplantation of ovarian tissue is a widely used method. During cryopreservation, ovarian tissue is exposed to mechanical and hypoxic stress resulting in follicular loss. Moreover, after retransplantation tissue vitality and follicle survival is limited due to ischemia. As follicular viability is of major importance for fertility and hormonal activity, the main focus is on improving vitality and viability of the grafts. In current protocols, ovarian medulla is discarded and merely cortex tissue is preserved. However, medulla tissue predominantly contains blood vessels, thereby obtaining high potential for revascularization processes and thereby supporting tissue vitality.
Study design, size, duration
This experimental laboratory work was performed during a period of ten months. The rapidly vascularized chorioallantoic-membrane (CAM) of fertilized chicken eggs was used as model system to investigate neovascularization, follicle survival and tissue vitality of different bovine ovarian grafts. In four independent experimental rows four different tissue types (isolated cortex, thick medulla-containing cortex (8 x 10 x 3 mm), thin medulla-containing cortex (5 x 10 x 3 mm) and sole medulla tissue were compared.
Participants/materials, setting, methods
Out of four bovine ovaries preserved from the slaughterhouse, in total 117 samples of the four different tissue types were primed and cryopreserved by the common slow-freezing protocol. After thawing, grafts were transplanted on separate CAMs at day four of fertilized eggs. After four days of incubation, blood vessels growing towards the grafts were counted. Subsequently, grafts were harvested, digested with collagenase and stained with Neutral Red® to determine the total amount of vital follicles.
Main results and the role of chance
To investigate the neovascularization, all graft-supplying blood vessels were determined and distinguished between small and thick vessels. Compared to sole cortex, there were more small vessels in the medulla-containing grafts (9,72 vs. 8,65). Especially thin medulla- containing cortex pieces exhibited the highest number of small vessels (9,90). Also in isolated medulla tissue an increased amount of small vessels was observed (9,79). However, the average number of big vessels was not significantly different in all four test groups (Cortex: 2,12; thin medulla-containing cortex: 1,69; thick medulla-containing cortex: 1,5; medulla: 2). The total number of all vessels differed from 10,76 (sole cortex) to 11,75 (medulla-containing grafts), indicating a support of neoangiogenesis by medulla tissue. To further examine whether medulla tissue also alters the amount of vital follicles, Neutral Red® stained vital follicles were determined in all different sample groups. Indeed, in medulla-containing cortex samples was an augmented average number of vital follicles (342,4) compared to sole cortex tissue (256,11). Most vital follicles were detectable in the thick medulla-containing cortex tissue (346,61), closely followed by the thin medulla-containing cortex grafts (338,19). As expected, there was just a rare amount of vital follicles in sole medulla grafts (8,13).
Limitations, reasons for caution
As the ovarian reserve in cattle is very individual, the prepared ovaries are different in their follicle amount. These individual differences may influence the number of counted follicles. Furthermore, the CAM model is only a short term experimental approach to investigate neovascularization and follicle survival.
Wider implications of the findings: According to our results, transplantation of human medulla-containing cortex appears promising. Keeping medulla tissue on the graft seems to improve both follicle viability and revascularization. Our findings need to be proven with human tissue, but might change the preparation of human ovarian tissue for fertility preservation in future.

Abstract
Zusammenfassung. Fragestellung: Es existiert eine Vielzahl von Begriffen für Verhaltenssüchte, die Mängel in Operationalisierung, Bezug zum Verhalten, Kompatibilität mit internationalen Klassifikationen sowie nicht stigmatisierender Nutzung aufweisen. Daher werden einheitliche Begriffe für Verhaltenssüchte benötigt. Methode: Im Rahmen einer Leitlinie zur Diagnostik und Behandlung Internetbezogener Störungen wurden Lösungen in Form eines Expertenkonsens entwickelt. Ergebnisse: Als Grundlage wurde die Einteilung von Verhaltenssüchten in der 11. Revision der International Classification of Diseases (ICD-11) genutzt. Es wurden die Begriffe Computerspielstörung (CSS) und Glücksspielstörung (GSS) für die beiden in ICD-11 enthaltenen Verhaltenssüchte gewählt sowie drei weitere spezifizierte Verhaltenssüchte vorgeschlagen: Soziale-Netzwerke-Nutzungsstörung (SNS), Shoppingstörung (ShS) und Pornografie-Nutzungsstörung (PNS). Für CSS, GSS und ShS wird weiterhin zwischen vorwiegend online oder vorwiegend offline unterschieden. Als Oberbegriff wird Störungen aufgrund von Verhaltenssüchten vorgeschlagen. Für Störungen aufgrund von Verhaltenssüchten, die sich vorwiegend auf online ausgeübte Verhaltensweisen beziehen, kann alternativ der Oberbegriff Internetnutzungsstörungen verwendet werden. Schlussfolgerung: Die vorgeschlagenen Termini weisen Verbesserungen im Vergleich zu uneindeutigen oder aus anderen Gründen ungünstigen Begriffen dar. Gleichzeitig konnte eine Kompatibilität mit der ICD-11 ermöglicht werden.

Abstract
BACKGROUND AND AIMS Consensus in acknowledging compulsive buying-shopping disorder (CBSD) as a distinct diagnosis has been lacking. Before research in this area can be advanced, it is necessary to establish diagnostic criteria in order to facilitate field trials. METHODS The study consisted of the following phases: (1) operationalization of a broad range of potential diagnostic criteria for CBSD, (2) two iterative rounds of data collection using the Delphi method, where consensus of potential diagnostic criteria for CBSD was reached by an international expert panel, and (3) interpretation of findings taking into account the degree of certainty amongst experts regarding their responses. RESULTS With respect to diagnostic criteria, there was clear expert consensus about inclusion of the persistent and recurrent experience of (a) intrusive and/or irresistible urges and/or impulses and/or cravings and/or preoccupations for buying/shopping; (b) diminished control over buying/shopping; (c) excessive purchasing of items without utilizing them for their intended purposes, (d) use of buying-shopping to regulate internal states; (e) negative consequences and impairment in important areas of functioning due to buying/shopping; (f) emotional and cognitive symptoms upon cessation of excessive buying/shopping; and (g) maintenance or escalation of dysfunctional buying/shopping behaviors despite negative consequences. Furthermore, support was found for a specifier related to the presence of excessive hoarding of purchased items. CONCLUSIONS The proposed diagnostic criteria can be used as the basis for the development of diagnostic interviews and measures of CBSD severity.

Abstract
Zusammenfassung
Einleitung Die Ausgangseinschränkungen und Kontaktverbote während der COVID-19-Pandemie haben mit dem Wegfall vieler beruflicher und privater Verpflichtungen und Strukturen massive Auswirkungen auf den Alltag der Allgemeinbevölkerung. Gleichzeitig verstärken sich für viele Menschen die Sorgen vor allem bezüglich ihrer finanziellen und beruflichen Zukunft. Eine vermehrte Nahrungsaufnahme stellt in dieser Situation eine mögliche Bewältigungsstrategie im Umgang mit den als unangenehm erlebten Gefühlen dar. Gleichzeitig fallen wegen der Ausgangs- und Kontaktbeschränkungen viele Möglichkeiten zur sportlichen Betätigung weg. Dies birgt die Gefahr einer Zunahme der kardiovaskulären Risikofaktoren in der Allgemeinbevölkerung und insbesondere für die Entstehung von Adipositas sowie Diabetes mellitus Typ 2. In dieser Studie untersuchten wir daher die Veränderungen des Ess- und Sportverhaltens in der Allgemeinbevölkerung in Deutschland während des Lockdowns im Frühjahr 2020.
Material und Methodik An der Onlinebefragung zu Veränderungen des Ess- und Sportverhaltens während des Lockdowns im Frühjahr 2020 konnten Frauen und Männer zwischen 18 und 80 Jahren aus der Allgemeinbevölkerung teilnehmen. Die Umfrage war online verfügbar zwischen dem 8. April und dem 11. Mai 2020.
Ergebnisse Von 3259 Teilnehmern gaben 40,3 % an, während des Lockdowns mehr als vor dessen Beginn gegessen zu haben, 38,3 % berichteten, während des Lockdowns weniger Sport gemacht zu haben als in der Zeit davor. Bei einer kombinierten Betrachtung der Verhaltensänderungen zeigten 58,5 % der Teilnehmer mindestens eine Verhaltensänderung, die dauerhaft potenziell negative gesundheitliche Folgen für sie haben könnte und die Entwicklung eines Diabetes mellitus Typ 2 fördert. Mit 18,5 % aller Studienteilnehmer gab die größte Gruppe an, weniger Sport gemacht und gleichzeitig mehr gegessen zu haben während des Lockdowns.
Schlussfolgerungen Diese Ergebnisse weisen darauf hin, dass es sowohl in der ambulanten als auch in der stationären Patientenversorgung in den nächsten Monaten wichtig sein wird, die Patienten auf die Gesundheitsrisiken, die sich durch eine Reduktion von sportlicher Aktivität und eine vermehrte Nahrungsaufnahme ergeben, hinzuweisen und ihr Ess- und Sportverhalten sowie die Veränderung des Körpergewichts zu beobachten, um eine Zunahme des Risikos für Diabetes mellitus Typ 2 in der Allgemeinbevölkerung zu verhindern.
