Abstract
BACKGROUND Findings from randomized trials (RCTs) on cervical pessary treatment to prevent spontaneous preterm birth are inconsistent. OBJECTIVES Our hypothesis suggests that adhering to the European Medical Device Regulation (MDR) and following the instructions for use are essential prerequisites for successful therapy. Conversely, the non-adherence to these guidelines will probably contribute to its failure. SEARCH STRATEGY AND SELECTION CRITERIA Based on validated criteria from integrity assessments we performed a systematic review identifying 14 RCTs evaluating the effect of cervical pessaries. DATA COLLECTION AND ANALYSIS We analyzed the implications of 14 criteria each accounting for 0-2 points of a score reflecting the clinical evaluation plan (CEP) as proposed by the MDR to evaluate the risk-benefit ratio of medical devices. MAIN RESULTS Seven RCTs in each singleton and twin pregnancies (5193 "cases") were included, detecting a high heterogeneity within control groups (I2 = 85% and 87%, respectively, P < 0.01). The CEP score varied from 11 to 26 points for all studies. The most common reasons for low scores and potential data compromise were poor recruitment rates, no (completed) power analysis, and no pre-registration, but mainly non-adherence to technical, biological, and clinical equivalence to the instructions for use as required by the MDR. All trials with score values greater than 20 had applied audit procedures. Within this group we found significantly reduced rates of spontaneous preterm birth at less than 34 weeks within the pessary group in singleton (odds ratio 0.28; 95% confidence interval 0.12-0.65) and twin pregnancies (odds ratio 0.30; 95% confidence interval 0.13-0.67). Similarly, there was a significant reduction in the composite poor neonatal outcome in singleton (odds ratio 0.25; 95% confidence interval 0.10-0.61) and twin pregnancies (odds ratio 0.54; 95% confidence interval 0.35-0.82) after a pessary as compared with controls. CONCLUSION Non-audited RCTs and meta-analyses mixing studies of different clinical quality as pre-defined by a CEP and the MDR pose the risk for erroneous conclusions.

Abstract
BACKGROUND Inappropriate drug prescriptions for patients with polypharmacy can have avoidable adverse consequences. We studied the effects of a clinical decision-support system (CDSS) for medication management on hospitalizations and mortality. METHODS This stepped-wedge, cluster-randomized, controlled trial involved an open cohort of adult patients with polypharmacy in primary care practices (=clusters) in Westphalia-Lippe, Germany. During the period of the intervention, their medication lists were checked annually using the CDSS. The CDSS warns against inappropriate prescriptions on the basis of patient-related health insurance data. The combined primary endpoint consisted of overall mortality and hospitalization for any reason. The secondary endpoints were mortality, hospitalizations, and high-risk prescription. We analyzed the quarterly health insurance data of the intention-to-treat population with a mixed logistic model taking account of clustering and repeated measurements. Sensitivity analyses addressed effects of the COVID-19 pandemic and other effects. RESULTS 688 primary care practices were randomized, and data were obtained on 42 700 patients over 391 994 quarter years. No significant reduction was found in either the primary endpoint (odds ratio [OR] 1.00; 95% confidence interval [0.95; 1.04]; p = 0.8716) or the secondary endpoints (hospitalizations: OR 1.00 [0.95; 1.05]; mortality: OR 1.04 [0.92; 1.17]; high-risk prescription: OR 0.98 [0.92; 1.04]). CONCLUSION The planned analyses did not reveal any significant effect of the intervention. Pandemic-adjusted analyses yielded evidence that the mortality of adult patients with polypharmacy might potentially be lowered by the CDSS. Controlled trials with appropriate follow-up are needed to prove that a CDSS has significant effects on mortality in patients with polypharmacy.

Abstract
Background: Intrusive memories form a core symptom of Posttraumatic Stress Disorder (PTSD). Based on concepts of visuospatial interference and memory-updating accounts, technological innovations aim to attenuate such intrusions using visuospatial interventions.Objective: This study aims to test the effect of a visuospatial Tetris-based intervention versus a verbal condition (Wiki) and a never-targeted control (no intervention) on intrusion frequency.Method: A randomized crossover trial was conducted including N = 38 PTSD patients who had at least 3 distinct intrusive memories of trauma. After both 2 weeks (intervention 1) and 4 weeks (intervention 2), one of the three memories was randomly selected and either the visuospatial intervention (memory reminder of a traumatic memory + Tetris) or verbal condition (reading a Wikipedia article + answering questions) was performed on their first memory in randomized order. In the week 4 session, the patient conducted the other intervention condition on their second memory (crossover). The third memory was never targeted (no intervention). Daily occurrence of intrusions over 8 weeks was collected using a diary and analysed using mixed Poisson regression models.Results: Overall, there was no significant reduction in intrusion frequency from either intervention compared to each other, and to no intervention control (relative risk Tetris/Wiki: 0.947; p = .31; relative risk no intervention/Tetris: 1.060; p = .15; relative risk no intervention/Wiki: 1.004; p = .92).Conclusions: There was no effect of either intervention on intrusions when administered in a crossover design where participants received both interventions. Design shortcomings and consequences for future studies are discussed.

Abstract
BACKGROUND Vulnerability to infectious diseases in refugees is dependent on country of origin, flight routes, and conditions. Information on specific medical needs of different groups of refugees is lacking. We assessed the prevalence of infectious diseases, immunity to vaccine-preventable diseases, and chronic medical conditions in children, adolescents, and adult refugees from Ukraine who arrived in Germany in 2022. METHODS Using different media, we recruited Ukrainian refugees at 13 sites between 9-12/2022. An antigen test for acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infection, serologies for a range of vaccine-preventable diseases, as well as interferon gamma release assays (IGRAs) for tuberculosis (TB), and SARS-CoV-2 were performed. We assessed personal and family history of chronic medical conditions, infectious diseases, vaccination status, and conditions during migration. RESULTS Overall, 1793 refugees (1401 adults and 392 children/adolescents) were included. Most participants were females (n = 1307; 72·3%) and from Eastern or Southern Ukraine. TB IGRA was positive in 13% (n = 184) of the adults and in 2% (n = 7) of the children. Serology-based immunological response was insufficient in approximately 21% (360/1793) of the participants for measles, 32% (572/1793) for diphtheria, and 74% (1289/1793) for hepatitis B. CONCLUSIONS We show evidence of low serological response to vaccine-preventable infections and increased LTBI prevalence in Ukrainian refugees. These findings should be integrated into guidelines for screening and treatment of infectious diseases in migrants and refugees in Germany and Europe. Furthermore, low immunity for vaccine-preventable diseases in Ukrainians independent of their refugee status, calls for tailor-made communication efforts.

Abstract
INTRODUCTION The delegation of medical services to rheumatology assistants (RFA) has proven to be safe and effective in the evaluation of the research project "StaerkeR". Afterwards, the experiences of the participating RFAs and rheumatologists with delegation were surveyed and discussed within the framework of an opinion research project. METHODS At the end of the project, the participating RFAs and rheumatologists were surveyed via an online questionnaire (quantitative analysis) (21 questions for physicians and 44 questions for RFAs). In addition, focus group meetings were held for the RFAs, which were led by a moderator and a secretary. The results of the focus group sessions (qualitative analyses) were analyzed according to the structured method of Kuckartz. RESULTS All 31 RFAs and 25 rheumatologists involved in the project participated in the online surveys and 9 RFAs took part in the 2 focus groups. In the online surveys, both the RFAs and the rheumatologists gave predominantly good to very good ratings with respect to RFA training, the implementation of delegation in the practices and outpatient clinics, the role of the RFAs and the overall evaluation of the delegation concept. In the focus group discussions, many possible limitations regarding acceptance and implementation of the delegation concept were mentioned. CONCLUSION The delegation of medical tasks to RFAs is a concept that is positively assessed and highly accepted by both sides, the rheumatologists and the RFAs. In a comparison between the individual practices and hospital outpatient departments, there is still a clear heterogeneity with respect to the willingness and logistical possibilities in the implementation of the delegation concept.

Abstract
PURPOSE In contrast to adults, immune protection against SARS-CoV-2 in children and adolescents with natural or hybrid immunity is still poorly understood. The aim of this study was to analyze different immune compartments in different age groups and whether humoral immune reactions correlate with a cellular immune response. METHODS 72 children and adolescents with a preceding SARS-CoV-2 infection were recruited. 37 were vaccinated with an RNA vaccine (BNT162b2). Humoral immunity was analyzed 3-26 months (median 10 months) after infection by measuring Spike protein (S), nucleocapsid (NCP), and neutralizing antibodies (nAB). Cellular immunity was analyzed using a SARS-CoV-2-specific interferon-γ release assay (IGRA). RESULTS All children and adolescents had S antibodies; titers were higher in those with hybrid immunity (14,900 BAU/ml vs. 2118 BAU/ml). NCP antibodies were detectable in > 90%. Neutralizing antibodies (nAB) were more frequently detected (90%) with higher titers (1914 RLU) in adolescents with hybrid immunity than in children with natural immunity (62.5%, 476 RLU). Children with natural immunity were less likely to have reactive IGRAs (43.8%) than adolescents with hybrid immunity (85%). The amount of interferon-γ released by T cells was comparable in natural and hybrid immunity. CONCLUSION Spike antibodies are the most reliable markers to monitor an immune reaction against SARS-CoV-2. High antibody titers of spike antibodies and nAB correlated with cellular immunity, a phenomenon found only in adolescents with hybrid immunity. Hybrid immunity is associated with markedly higher antibody titers and a higher probability of a cellular immune response than a natural immunity.

Abstract
BACKGROUND Relapse risk after delivery is increased in women with active multiple sclerosis (MS), the best strategy to reduce it is unknown. We aimed to assess the association of four different postpartum strategies with relapses during the first 6 months post partum. METHODS This cohort study includes data prospectively collected through structured telephone interviews from the German Multiple Sclerosis and Pregnancy Registry. Pregnancies with active MS (fingolimod or natalizumab treatment OR relapse within 1 year before pregnancy) and postpartum follow-up of ≥6 months were included. We compared four strategies: (1) intention to breastfeed exclusively without disease-modifying therapy (DMT) (exclusive breast feeding ≥2 months or switching to non-exclusive/weaning within 2 weeks after a relapse during the first 2 months), (2) early treatment with natalizumab/fingolimod and (3) other DMT initiated within 6 weeks post partum before a relapse. If women did not or only partially breastfed, or started DMT≤6 weeks after delivery after a relapse or later, we assumed (4) no-DMT-no-exclusive- breastfeeding-strategy. Main outcome was time to postpartum MS relapses. RESULTS In 867 women with 911 pregnancies, most (n=416) intended to breastfeed exclusively or had no-DMT-no-exclusive-breastfeeding-strategy (n=290); fewer started fingolimod (n=38), natalizumab (n=74) or another DMT (n=93) early. Recurrent time-to-event analysis showed a statistically significant reduction in relapse hazard only with the natalizumab/fingolimod-strategy as of months 3-4 post partum compared with intention-to-breastfeed-exclusively-strategy. The very early relapse risk was highest in no-DMT-no-exclusive-breastfeeding-strategy. CONCLUSION In active MS, an early postpartum treatment strategy should be determined well before delivery. Natalizumab/fingolimod-strategy reduced postpartum relapse hazard from month 3, but none diminished the early postpartum relapse hazard.

Both are closely related and hard to differentiate as most standard cognitive test batteries are auditory-based and hearing-impaired individuals perform worse also in non-auditory test batteries. Therefore, reference data for hearing-impaired are mandatory. METHODS The computer-based battery ALAcog assesses multiple cognitive domains, such as attention, (delayed) memory, working memory, inhibition, processing speed, mental flexibility and verbal fluency. A data set of 201 bilaterally hearing-impaired subjects aged ≥ 50 (mean 66.6 (SD 9.07)) was analysed. The LMS method, estimated curves for the 10th, 25th, 50th, 75th and 90th percentile were calculated, and classified according to age, starting from the age of 50. RESULTS Cognitive function shows a decline in all subtests as people age, except for verbal fluency, which remains almost stable over age. The greatest declines were seen in recall and delayed recall and in mental flexibility. Age and hearing ability did not correlate (p = 0.68). However, as people age, inter-subject variability of cognitive test results increases. This was especially the case for inhibition. Cognitive function was not correlated with hearing ability (each p ≥ 0.13). CONCLUSION The present results make an approach to establish reference data for a comprehensive non-auditory test battery in a large sample of elderly hearing-impaired people which can be used as a simple tool to better contextualise cognitive performance beyond mean and median scores.

Abstract
Internet Use Disorders (IUD) have a relevant effect on national economies. In the randomized, controlled, multicenter, prospective, and single-blinded OMPRIS study (pre-registration number DRKS00019925; Innovation Fund of the Joint Federal Committee of Germany, grant number 01VSF18043), a four-week online program to reduce media addiction symptoms, was evaluated for cost-effectiveness. The intervention group (IG) was compared to a waiting control group (WCG) from German statutory health insurance (SHI) and a societal perspective. Resource use, namely indirect and direct (non) medical costs, was assessed by a standardized questionnaire at baseline and after the intervention. Additionally, intervention costs were calculated. Determining the Reliable Change Index (RCI) based on the primary outcome, assessed by the "Scale for the Assessment of Internet and Computer Game Addiction" (AICA-S), individuals with and without reliable change (RC) were distinguished. The incremental cost-effectiveness ratio was calculated using the difference-in-difference approach. There were 169 (IG n = 81, WCG n = 88) persons included in the analysis. The mean age was 31.9 (SD 12.1) years. A total of 75.1% were male, and 1.8% diverse. A total of 65% (IG) and 27% (WCG) had an RC. The cost per person with RC was about EUR 860 (SHI) and EUR 1110 (society). The intervention leads to an improvement of media addiction symptoms at moderate additional costs.

Abstract
OBJECTIVES Advance care discussions are a useful communication tools for medical preferences and beneficial for shared decision-making processes in hospital settings. The present study developed the first screening tool for need for advance care planning (ACP). METHODS In phase 1 (n=92), items were evaluated using feasibility analysis and item reduction. In phase 2 (n=201), reduced screening items were analysed for predictive value of need for ACP. Statistical analysis included receiver-operating characteristics analysis (area under the curve>0.80), optimal cut-off based on sensitivity and specificity, interpretation of OR and construct validity using correlation with death anxiety, communication avoidance within families and trust based on the relationship with the treating physician. RESULTS Participants in both phases were approximately 60 years old with non-curative prognosis. After item reduction, predictive values of four possible items with good item difficulty and discrimination were compared for mild, moderate and great levels of death anxiety. A two-item combination of I am burdened by thoughts of an unfavourable course of the disease and I am burdened by the feeling of being ill-prepared for the end of life showed best prediction of death anxiety and communication avoidance. Clinical cut-off at sum-score ≥6 was of high sensitivity (95%) and specificity (81%). Previous use of social support and readiness for ACP was related to higher chance of interest in ACP. CONCLUSION Screening for need of ACP is possible with two objective items and one subjective item. Positive screening therefore indicates when to offer ACP discussions and provides routine estimation of ACP need in clinical practice.

Abstract
Delay in diagnosing multidrug-resistant tuberculosis (MDR-pTB) in children prolongs time to effective treatment. Data on risk factors for pediatric MDR from low-incidence countries are scarce. Retrospective nationwide case-control study to analyze MDR-pTB cases in Germany between 2010 and 2020 in comparison to a drug-susceptible (DS)-pTB group. We included 52 MDR cases (24 tuberculosis (TB), 28 TB infection (TBI); mean age 7.3 years) and 56 DS cases (31 TB, 26 TBI; mean age 7.9 years). Groups were similar for sex, household size, and migration background. Compared to the DS group, more children with MDR were born in the Commonwealth of Independent States (CIS) (22% MDR-pTB vs. 13% DS-pTB, n.s.) and had more MDR index cases (94% MDR-pTB, 5% DS-pTB, p < 0.001). The interval between first healthcare contact and initiation of effective therapy was significantly longer in MDR-pTB (47 days) than in DS-pTB (11 days, p < 0.001), correlating with disease progression. Treatment for MDR-pTB was successful in 74%, but 22% experienced long-term adverse effects (e.g., hepatopathy, hearing loss). CONCLUSIONS Close contact to MDR cases or birth in MDR-TB-high-incidence countries are risk factors for MDR-pTB. Early identification of potential MDR index cases by contact investigation, and susceptibility testing in children from high-burden MDR-TB countries are essential for timely diagnosis and treatment, reducing the severity of disease and treatment side effects.

WHAT IS KNOWN •Management of children with MDR-TB remains challenging due to difficulties in diagnosing MDR-TB (lack of information on MDR index case, lack of microbiological confirmation in paucibacillary disease). •Choice of treatment regimen and monitoring of side effects. WHAT IS NEW •Children with an MDR-TB index or born in a MDR-TB-high-incidence country are at higher risk of developing MDR-TB in a low incidence country. •The time lag to initiate treatment in MDR-TB is longer than in DS-TB and MDR-TB treatment involves a higher risk of adverse effects in longer treatment regimens especially with injectables.

Abstract
Background Evidence-based treatments for internet use disorders (IUDs) are limited, and online therapy approaches are poorly studied. We investigated the efficacy of a manualised therapist-guided online intervention (OMPRIS) to reduce IUD symptoms and improve psychological well-being. Methods In this multicentre, two-arm, single-blinded trial, individuals ≥16 years suffering from IUD symptoms were recruited in Germany from August 16, 2020, to March 11, 2022, through media advertisements and healthcare providers. Participants were randomly allocated by sequential balancing randomisation (1:1) to either the manualised webcam-based OMPRIS intervention or a waitlist control (WLC) group. OMPRIS provided strategies from motivational interviewing, behavioural therapy, and social counselling. The primary outcome at the end of treatment was a reduction in IUD symptoms as measured by the Assessment of Internet and Computer Scale (AICA-S). Follow-up assessments were conducted at 6 weeks and 6 months. Analyses were performed in the intention-to-treat population. This trial was registered (German Clinical Trial Register, DRKS00019925) and has been completed. Findings A total of 180 individuals were randomly assigned to the OMPRIS intervention (n = 89) or WLC (n = 91) arm. After treatment, 81 (91.0%) participants in the OMPRIS intervention group and 88 (96.7%) in the WLC group completed the outcome assessment. The ANCOVA model showed that OMPRIS participants had a significantly greater reduction in AICA-S scores from baseline (mean score 12.1 [SD 4.6]) to post-treatment (6.8 [5.2]) than those in the WLC group (from 12.6 [5.1] to 11.0 [5.4]; estimated mean difference -3.9; [95% CI -5.2 to -2.6]; p < 0.0001; d = 0.92). No adverse events were reported to the trial team. Interpretation Webcam-based OMPRIS therapy was effective and superior to waiting list conditions in reducing IUD symptoms. Webcam-based, specialised online therapy thus increases IUD treatment options. Funding German Innovation Fund of Germany's Federal Joint Committee (G-BA), grant number 01VSF18043.

Abstract
OBJECTIVES Various measures are used to improve the quality of stroke care. In Germany, these include concentrating treatment in specialized facilities (stroke units), mandatory quality comparisons of hospitals in some German states, and treatment according to prespecified structure and process specifications (neurological complex treatment 8-981 or 8-98b). These measures have previously only been analyzed individually and regarding short-term patient outcomes. This study analyzes these measures in combination, considering patients' comorbidities as well as stroke severity in a longitudinal perspective. MATERIALS/METHODS Analyses were based on data from 243,415 insurees of Germany's biggest health insurance (AOK) admitted to hospitals between 2007 and 2017 with cerebral infarction. Mortality risk was calculated using Cox regressions adjusted for various covariates. Kaplan-Meier analyses were differentiated by treatment site (stroke unit/external quality assurance/ Federal State Consortium of Quality Assurance Hesse - LAGQH) were performed, followed by log-rank tests and p-value adjustment. Trend analyses were performed for treatment types in combination with treatment sites. RESULTS All analyses showed significant advantages for patients who received Neurological Complex Treatment, especially when the treatment was performed under external quality assurance conditions and/or in stroke units. There was an increasing frequency of specialized stroke treatment. CONCLUSIONS Quality-enhancing structures and processes are associated with a lower mortality risk after stroke. There appears to be evidence of a cascading benefit from the implementation of neurological complex treatment, external quality assurance, and ultimately, stroke units. Consecutively, care should be concentrated in hospitals that meet these specifications. However, since measures are often applied in combination, it remains unclear which specific measures are crucial for patient outcome.

Abstract
Visualization is a key aspect of communicating the results of any study aiming to estimate causal effects. In studies with time-to-event outcomes, the most popular visualization approach is depicting survival curves stratified by the variable of interest. This approach cannot be used when the variable of interest is continuous. Simple workarounds, such as categorizing the continuous covariate and plotting survival curves for each category, can result in misleading depictions of the main effects. Instead, we propose a new graphic, the survival area plot, to directly depict the survival probability over time and as a function of a continuous covariate simultaneously. This plot utilizes g-computation based on a suitable time-to-event model to obtain the relevant estimates. Through the use of g-computation, those estimates can be adjusted for confounding without additional effort, allowing a causal interpretation under the standard causal identifiability assumptions. If those assumptions are not met, the proposed plot may still be used to depict noncausal associations. We illustrate and compare the proposed graphics to simpler alternatives using data from a large German observational study investigating the effect of the Ankle-Brachial Index on survival. To facilitate the usage of these plots, we additionally developed the contsurvplot R-package, which includes all methods discussed in this paper.

Abstract
BACKGROUND Despite attempts to improve the cross-sectoral flow of information, difficulties remain in routine healthcare. The resulting negative impact on continuity of care is often associated with poor health outcomes, especially in older patients. Our intervention aims to increase information availability with respect to medications and health conditions at the interface between inpatient and outpatient care and to contribute towards improving the quality of care in older patients. This pilot study focuses on feasibility and implementability. METHODS The idea of the complex intervention has been developed in a previous study. This intervention will be tested in a prospective, multicenter, cluster-randomized (via web tool), controlled pilot trial with two parallel study arms (intervention and control group). The pilot study will be conducted in 20 general practices in Hesse and Saxony (Germany) and include 200 patients (≥ 65 years of age with multimorbidity and polypharmacy) recruited by the practices. Practice staff and patients will be blinded. We will use qualitative and quantitative methods to assess the feasibility and implementability of the intervention and the study design in a process evaluation covering topics ranging from expectations to experiences. In addition, the feasibility of proposed outcome parameters for the future definitive trial will be explored. The composite endpoint will include health-related patient outcomes (hospitalization, falls, and mortality using, e.g., the FIMA questionnaire), and we will assess information on medications (SIMS questionnaire), symptoms and side effects of the medication (pro-CTCAE questionnaire), and health literacy (HLQ questionnaire). Data will be collected at study begin (baseline) and after 6 months. Furthermore, the study will include surveys and interviews with patients, general practitioners, and healthcare assistants. DISCUSSION The intervention was developed using a participatory approach involving stakeholders and patients. It aims to empower general practice teams as they provide patient-centered care and play a key role in the coordination and continuity of care.

Abstract
BACKGROUND AND OBJECTIVE Discontinuation of fingolimod ≥2 months before pregnancy is recommended to minimize potential teratogenicity. The magnitude of MS pregnancy relapse risk, particularly severe relapses, after fingolimod cessation is unclear, as is whether this risk is reduced by pregnancy or modifiable factors. METHODS Pregnancies who stopped fingolimod treatment within 1 year before or during pregnancy were identified from the German MS and Pregnancy Registry. Data were collected through structured telephone-administered questionnaires and neurologists' notes. Severe relapses were defined as a ≥2.0 increase in Expanded Disability Status Scale (EDSS) or new or worsening relapse-related ambulatory impairment. Women who continued to meet this definition 1 year postpartum were classified as reaching the Severe Relapse Disability Composite Score (SRDCS). Multivariable models accounting for measures of disease severity and repeated events were used. RESULTS Of the 213 pregnancies among 201 women (mean age at pregnancy onset 32 years) identified, 56.81% (n = 121) discontinued fingolimod after conception. Relapses during pregnancy (31.46%) and the postpartum year (44.60%) were common. Nine pregnancies had a severe relapse during pregnancy and additional 3 during the postpartum year. One year postpartum, 11 of these (6.32% of n = 174 with complete EDSS information) reached the SRDCS. Adjusted relapse rates during pregnancy were slightly higher compared with the year before pregnancy (relapse rate ratio = 1.24, 95% CI 0.91-1.68). Neither exclusive breastfeeding nor resuming fingolimod within 4 weeks of delivery were associated with a reduced risk of postpartum relapses. Most pregnancies relapsed during the first 3 months postpartum (n = 55/204, 26.96%). DISCUSSION Relapses during pregnancy after fingolimod cessation are common. Approximately 6% of women will retain clinically meaningful disability from these pregnancy-related, fingolimod cessation relapses 1 year postpartum. This information should be shared with women on fingolimod desiring pregnancy, and optimizing MS treatment with nonteratogenic approaches should be discussed.

Abstract
BACKGROUND In on-pump cardiac surgery, lungs are at high risk of periprocedural organ impairment because of atelectasis formation, ventilator-induced lung injury, and hyperinflammation due to the cardiopulmonary bypass which results in postoperative pulmonary complications in half of this patient population. The new ventilation mode flow-controlled ventilation (FCV) uniquely allows full control of ins- and expiratory airway flows. This approach reduces the mechanical power of invasive ventilation as a possible cause of ventilator-induced lung injury. The scope of FLOWVENTIN HEARTSURG is to compare perioperative individualized FCV with best clinical practice pressure-controlled ventilation (PVC) modes in patients with elective on-pump cardiac surgery procedures. We hypothesize that the postoperative inflammatory response can be reduced by the perioperative application of FCV compared to PCV. METHODS FLOWVENTIN HEARTSURG is a single-center, randomized, parallel-group trial with two intervention arms: perioperative PCV modes (n = 70, PCV group) with an individualized positive end-expiratory pressure (PEEP) and a tidal volume of 6-8 ml/kg predicted bodyweight compared to perioperative FCV (n = 70, FCV group) with an individualized PEEP and driving pressure, resulting in a liberal tidal volume. As the primary study endpoint interleukin 8 plasma level is assessed 6 h after cardiopulmonary bypass as a surrogate biomarker of systemic and pulmonary inflammation. As secondary aims clinically relevant patient outcomes are analyzed, e.g., perioperative lung function regarding oxygenation indices, postoperative pulmonary and extra-pulmonary complications, SIRS-free days as well as ICU and total inpatient stays. As additional sub-studies with an exploratory approach perioperative right ventricular function parameters are assessed by echocardiography and perioperative lung aeration by electrical impedance tomography. DISCUSSION Current paradigms regarding protective low tidal volume ventilation are consciously left in the FCV intervention group in order to reduce mechanical power as a determinant of ventilator-induced lung injury in this high-risk patient population and procedures. This approach will be compared in a randomized controlled trial with current best clinical practice PCV in FLOWVENTIN HEARTSURG. TRIAL REGISTRATION German Clinical Trials Register DRKS00018956 .

Abstract
PURPOSE Microsatellite instability (MSI) due to mismatch repair (MMR) defects accounts for 15-20% of colon cancers (CC). MSI testing is currently standard of care in CC with immunohistochemistry of the four MMR proteins representing the gold standard. Instead, label-free quantum cascade laser (QCL) based infrared (IR) imaging combined with artificial intelligence (AI) may classify MSI/microsatellite stability (MSS) in unstained tissue sections user-independently and tissue preserving. METHODS Paraffin-embedded unstained tissue sections of early CC from patients participating in the multicentre AIO ColoPredict Plus (CPP) 2.0 registry were analysed after dividing into three groups (training, test, and validation). IR images of tissue sections using QCL-IR microscopes were classified by AI (convolutional neural networks [CNN]) using a two-step approach. The first CNN (modified U-Net) detected areas of cancer while the second CNN (VGG-Net) classified MSI/MSS. End-points were area under receiver operating characteristic (AUROC) and area under precision recall curve (AUPRC). RESULTS The cancer detection in the first step was based on 629 patients (train n = 273, test n = 138, and validation n = 218). Resulting classification AUROC was 1.0 for the validation dataset. The second step classifying MSI/MSS was performed on 547 patients (train n = 331, test n = 69, and validation n = 147) reaching AUROC and AUPRC of 0.9 and 0.74, respectively, for the validation cohort. CONCLUSION Our novel label-free digital pathology approach accurately and rapidly classifies MSI vs. MSS. The tissue sections analysed were not processed leaving the sample unmodified for subsequent analyses. Our approach demonstrates an AI-based decision support tool potentially driving improved patient stratification and precision oncology in the future.

Abstract
Treatment specific survival curves are an important tool to illustrate the treatment effect in studies with time-to-event outcomes. In non-randomized studies, unadjusted estimates can lead to biased depictions due to confounding. Multiple methods to adjust survival curves for confounders exist. However, it is currently unclear which method is the most appropriate in which situation. Our goal is to compare forms of inverse probability of treatment weighting, the G-Formula, propensity score matching, empirical likelihood estimation and augmented estimators as well as their pseudo-values based counterparts in different scenarios with a focus on their bias and goodness-of-fit. We provide a short review of all methods and illustrate their usage by contrasting the survival of smokers and non-smokers, using data from the German Epidemiological Trial on Ankle-Brachial-Index. Subsequently, we compare the methods using a Monte-Carlo simulation. We consider scenarios in which correctly or incorrectly specified models for describing the treatment assignment and the time-to-event outcome are used with varying sample sizes. The bias and goodness-of-fit is determined by taking the entire survival curve into account. When used properly, all methods showed no systematic bias in medium to large samples. Cox regression based methods, however, showed systematic bias in small samples. The goodness-of-fit varied greatly between different methods and scenarios. Methods utilizing an outcome model were more efficient than other techniques, while augmented estimators using an additional treatment assignment model were unbiased when either model was correct with a goodness-of-fit comparable to other methods. These "doubly-robust" methods have important advantages in every considered scenario.

Abstract
BACKGROUND Internet use disorder (IUD) is a new type of behavioral addiction in the digital age. At the same time, internet applications and eHealth can also provide useful support in medical treatment. OBJECTIVE The purpose of this study is to examine if an internet-based eHealth service can reach individuals with IUD. In particular, it should be investigated whether both male and female individuals with more severe IUDs can be reached. METHODS Data were retrieved from the OMPRIS (online-based motivational intervention to reduce problematic internet use and promote treatment motivation in internet gaming disorder and internet use disorder) project (DRKS00019925), an internet-based motivational intervention to reduce problematic internet use and promote treatment motivation in internet gaming disorder and IUD. During the recruitment process (August 2020-March 2022), a total of 3007 individuals filled out the standardized scale for the assessment of internet and computer game addiction (AICA-S). The assessment was accessible via the project homepage. There was no preselection of participants at this stage of the study; however, the offer was addressed to people with hazardous internet use and IUDs. The web-based assessment was free and could be found via search engines, but attention was also drawn to the service via newspaper articles, radio reports, and podcasts. RESULTS Out of 3007 who participated in the web-based self-assessment, 1033 (34.4%) are female, 1740 (57.9%) are male, 67 (2.2%) are diverse individuals, and 167 (5.5%) did not disclose their gender. The IUD symptom severity score showed a wide range between the AICA-S extreme values of 0 and 27 points. On average, the total sample (mean 8.19, SD 5.47) was in the range of hazardous IUD behavior (AICA-S cutoff>7.0). Furthermore, 561 individuals (18.7% of the total sample; mean 17.42, SD 3.38) presented severe IUD (AICA-S cutoff>13.5). Focusing on female and male participants, 20.9% (363/1740) of the men and 14.9% (151/1033) of the women scored above 13.5 points, which can be considered pathological IUD behavior (χ22,2773=16.73, P<.001, effect size: Cramér V=0.078). Unemployment, being in vocational training or studying at a university, and being male were significantly associated with high IUD symptoms. CONCLUSIONS Using a large sample, the study showed that both mildly and severely IUD-affected individuals can be reached via the internet. An internet-based eHealth offer can thus be a good way to reach patients with IUD where they are addicted-on the internet. In addition, eHealth services increase the likelihood of reaching female patients, who hardly ever come to specialized outpatient clinics and hospitals. Since social problems, especially unemployment, have a strong association with disease severity, the integration of social counseling into treatment seems advisable in terms of a multidisciplinary approach.

Abstract
Background A profound inflammation-mediated lung injury with long-term acute respiratory distress and high mortality is one of the major complications of critical COVID-19. Immunoglobulin M (IgM)-enriched immunoglobulins seem especially capable of mitigating the inflicted inflammatory harm. However, the efficacy of intravenous IgM-enriched preparations in critically ill patients with COVID-19 is largely unclear. Methods In this retrospective multicentric cohort study, 316 patients with laboratory-confirmed critical COVID-19 were treated in ten German and Austrian ICUs between May 2020 and April 2021. The primary outcome was 30-day mortality. Analysis was performed by Cox regression models. Covariate adjustment was performed by propensity score weighting using machine learning-based SuperLearner to overcome the selection bias due to missing randomization. In addition, a subgroup analysis focusing on different treatment regimens and patient characteristics was performed. Results Of the 316 ICU patients, 146 received IgM-enriched immunoglobulins and 170 cases did not, which served as controls. There was no survival difference between the two groups in terms of mortality at 30 days in the overall cohort (HRadj: 0.83; 95% CI: 0.55 to 1.25; p = 0.374). An improved 30-day survival in patients without mechanical ventilation at the time of the immunoglobulin treatment did not reach statistical significance (HRadj: 0.23; 95% CI: 0.05 to 1.08; p = 0.063). Also, no statistically significant difference was observed in the subgroup when a daily dose of ≥ 15 g and a duration of ≥ 3 days of IgM-enriched immunoglobulins were applied (HRadj: 0.65; 95% CI: 0.41 to 1.03; p = 0.068). Conclusions Although we cannot prove a statistically reliable effect of intravenous IgM-enriched immunoglobulins, the confidence intervals may suggest a clinically relevant effect in certain subgroups. Here, an early administration (i.e. in critically ill but not yet mechanically ventilated COVID-19 patients) and a dose of ≥ 15 g for at least 3 days may confer beneficial effects without concerning safety issues. However, these findings need to be validated in upcoming randomized clinical trials. Trial registrationDRKS00025794, German Clinical Trials Register, https://www.drks.de. Registered 6 July 2021.

Abstract
INTRODUCTION To date, there have only been provisional recommendations about the appropriate gestational weight gain in twin pregnancies. This study aimed to contribute evidence to this gap of knowledge. MATERIAL AND METHODS Using a cohort of 10 603 twin pregnancies delivered between 2000 and 2015 in the state of Hessen, Germany, the individual and combined impact of maternal body mass index and gestational weight gain on maternal and neonatal outcomes was analyzed using uni- and multivariable logistic regression models. The analysis used newly defined population-based quartiles of gestational weight gain in women carrying twin pregnancies (Q1: <419.4 g/week [low weight gain], Q2-Q3: 419.4-692.3 g/week [optimal weight gain], Q4: >692.3 g/week [high weight gain]) and the World Health Organization body mass index classification. RESULTS Pre-pregnancy body mass index ≥25 kg/m2 was associated with significantly increased rates of cesarean deliveries (aOR1.2, 95% CI: 1.01-1.41) and pregnancy-induced hypertensive disorders (aOR 1.53, 95% CI: 1.11-2.1) but not with any adverse neonatal outcome. Perinatal mortality (aOR 2.23, 95% CI: 1.38-3.6), preterm birth (aOR 1.88, 95% CI: 1.58-2.25), APGAR'5 < 7 (aOR 1.61, 95% CI: 1.19-2.17) and admissions to the neonatal intensive care unit (aOR 1.6, CI: 1.38-1.85) were increased among women with low gestational weight gain. Rates of cesarean deliveries were high in both women with low (aOR 1.25, 95% CI: 1.05-1.48) and high gestational weight gain (aOR 1.17, 95% CI: 1.01-1.35). A high gestational weight gain was also associated with higher rates of hypertensive disorders in pregnancy (aOR 2.32, 95% CI: 1.79-3.02) and postpartum hemorrhage (aOR 1.72, 95%CI: 1.12-2.63). The risk of preterm birth, low Apgar scores and NICU admissions showed a converse linear relation with pre-pregnancy body mass index in women with low gestational weight gain. CONCLUSIONS In twin pregnancies, nonoptimal weekly maternal weight gain seems to be strongly associated with maternal and neonatal adverse outcomes. Since gestational weight gain is a modifiable risk factor, health care providers have the opportunity to counsel pregnant women with twins and target their care accordingly. Additional research to confirm the validity and generalizability of our findings in different populations is warranted.

Abstract
To compare the impact of lifestyle interventions for overweight and obese pregnant women a systematic review and meta-analysis was conducted using pre-registration and audit of the interventions as selection criteria. PubMed, Web of Science and CENTRAL were searched for randomized controlled trials examining diet, exercise, combined interventions or associated behavioral therapy. Trials were selected if they reported one of the primary outcomes (gestational diabetes, hypertensive disorders, perinatal mortality, admission to neonatal intensive care unit). Results were established from the total group and separately from pre-registered or clinically audited studies. Out of 1304 titles, 28 randomized controlled trials were included. Among the primary outcomes only hypertensive disorders were significantly reduced by exercise in the total group: odds ratio 0.52 (95% confidence interval 0.28 to 0.96, four trials, 1324 participants). When behavioral therapy supported combined interventions, maternal weight gain, (Standardized Mean Difference -0.16 kilogram; 95% confidence interval -0.28 to -0.04, four trials, 2132 participants) and neonatal birthweight, (Standardized Mean Difference -0.4 gram; 95% confidence interval -0.62 to -0.18, five trials, 1058 participants), were significantly reduced within the total group and both specified meta-analyses. Higher frequencies of physical activity improved the results. Risk of bias, assessed with the Cochrane Tool, was low to moderate. Elements of behavioral therapy might better prevent adverse effects of maternal obesity when combined with lifestyle interventions. Unfortunately, high heterogeneity due to different intervention and population characteristics was a limiting factor. Future studies should also focus on increased intensities of physical activity.

Abstract
Socio-economic conditions and social attitudes are known to represent epidemiological determinants. Credible knowledge on socio-economic driving factors of the COVID-19 epidemic is still incomplete. Based on linear random effects regression, an ecological model is derived to estimate COVID-19 incidence in German rural/urban districts from local socio-economic factors and popularity of political parties in terms of their share of vote. Thereby, records provided by Germany's public health institute (Robert Koch Institute) of weekly notified 7-day incidences per 100,000 inhabitants per district from the outset of the epidemic in 2020 up to December 1, 2021, are used to construct the dependent variable. Local socio-economic conditions including share of votes, retrieved from the Federal Statistical Office of Germany, have been used as potential risk factors. Socio-economic parameters like per capita income, proportions of protection seekers and social benefit claimants, and educational level have negligible impact on incidence. To the contrary, incidence significantly increases with population density and we observe a strong association with vote shares. Popularity of the right-wing party Alternative for Germany (AfD) bears a considerable risk of increasing COVID-19 incidence both in terms of predicting the maximum incidences during three epidemic periods (alternatively, cumulative incidences over the periods are used to quantify the dependent variable) and in a time-continuous sense. Thus, districts with high AfD popularity rank on top in the time-average regarding COVID-19 incidence. The impact of the popularity of the Free Democrats (FDP) is markedly intermittent in the course of time showing two pronounced peaks in incidence but also occasional drops. A moderate risk emanates from popularities of the Green Party (GRÜNE) and the Christian Democratic Union (CDU/CSU) compared to the other parties with lowest risk level. In order to effectively combat the COVID-19 epidemic, public health policymakers are well-advised to account for social attitudes and behavioral patterns reflected in local popularities of political parties, which are conceived as proper surrogates for these attitudes. Whilst causal relations between social attitudes and the presence of parties remain obscure, the political landscape in terms of share of votes constitutes at least viable predictive "markers" relevant for public health policy making.

Abstract
Introduction Socio-economic and ethnic background have been discussed as possible risk factors for SARS-CoV-2 infections in children. Improved knowledge could lead to tailored prevention strategies and help improve infection control. Aim We aimed to identify risk factors for SARS-CoV-2 infections in children in the first and second wave of the pandemic. Methods We performed an observational population-based cohort study in children (6 months–18 years) scheduled for legally required preventive examination and their parents in a metropolitan region in Germany. Primary endpoint was the SARS-CoV-2 seroconversion rate during the study period. Risk factors assessed included age, pre-existing medical conditions, socio-economic factors and ethnicity. Results We included 2,124 children and their parents. Seroconversion rates among children in all age groups increased 3–4-fold from June 2020 to February 2021. Only 24 of 58 (41%) seropositive children reported symptoms. In 51% of infected children, at least one parent was also SARS-CoV-2-positive. Low level of parental education (OR = 3.13; 95% CI: 0.72–13.69) non-significantly increased the risk of infection. Of the total cohort, 38.5% had a migration background, 9% of Turkish and 5% of Middle Eastern origin, and had the highest risk for SARS-CoV-2 infections (OR = 6.24; 95% CI: 1.38–28.12 and OR = 6.44 (95% CI: 1.14–36.45) after adjustment for other risk factors. Conclusion In the second half of 2020, seroprevalence for SARS-CoV-2 in children increased especially in families with lower-socioeconomic status. Culture-sensitive approaches are essential to limit transmission and could serve as a blueprint for vaccination strategies.

Abstract
BACKGROUND older patients are less frequently treated in stroke units (SUs). Clinicians do not seem convinced that older patients benefit from specialised treatment in SU similarly to younger patients. OBJECTIVE our study aimed to compare older patients' long-term outcomes with and without SU treatment. METHODS this study used routinely collected health data of 232,447 patients admitted to hospitals in Germany between 2007 and 2017 who were diagnosed with ischaemic stroke (ICD 10 I63). The sample included 29,885 patients aged ≥90 years. The outcomes analysed were 10-, 30- and 90-day, and 1-, 3- and 5-year mortality and the combinations of death or recurrence, inpatient treatment and increase in long-term care needs. Bivariate chi-square tests and multivariable logistic regression analyses were used, adjusting for the covariates age, sex, co-morbidity, long-term care needs before stroke and socioeconomic status of the patients' region of origin. RESULTS between 2007 and 2017, 57.1% of patients aged <90 years and 49.6% of those aged ≥90 years were treated in a SU. The 1-year mortality rate of ≥90-year-olds was 56.9 and 61.9% with and without SU treatment, respectively. The multivariable-adjusted risk of death in ≥90-year-olds with SU treatment was odds ratio (OR) = 0.67 (95% confidence interval [CI] = 0.62-0.73) 10 days after the initial event and OR = 0.76 (95% CI = 0.71-0.82) 3 years after stroke. CONCLUSIONS even very old patients with stroke benefit from SU treatment in the short and long term. Therefore, SU treatment should be the norm even in older patients.

Abstract
Background The Implementation Leadership Scale (ILS) was developed to assess leadership behavior with regard to being proactive, knowledgeable, supportive, or perseverant in implementing evidence-based practices (EBPs). As part of a study on the implementation of a digitally supported polypharmacy management application in primary care, the original ILS was translated and validated for use in the German language. Rationale This study aimed to translate the original ILS into German and evaluate its psychometric properties. Methods The validation sample consisted of 198 primary care physicians in a cluster-randomized controlled trial in which the intervention group implemented a digitally supported clinical decision support system for polypharmacy management. The ILS was assessed using a 12-item scale. The study included a process evaluation with two evaluation waves between 2019 and 2021. The ILS was used within this process evaluation study to assess the leadership support with regard to the implementation of the polypharmacy management. The ILS was translated in a multi-step process, including pre-testing of the instrument and triple, back-and-forth translation of the instrument. We tested the reliability (Cronbach’s alpha) and validity (construct and criterion-related validity) of the scale. Results The four-dimensional structure of the instrument was confirmed (comparative fit index = .97; root mean square error of approximation = .06). Convergent validity was demonstrated by correlations with organizational innovation climate, social capital, and workload, which was consistent with the proposed hypothesis. Criterion-related validity of the ILS was demonstrated by predicting the organizational readiness for change scores using structural equation modeling. The reliability of the scale was good (α = .875). Conclusion The German version of the ILS created in this study is a reliable and valid measure. The original four-dimensional structure of the ILS was confirmed in a primary care setting. Further psychometric testing is needed to establish the validity and reliability of the ILS and to transfer it to other health care settings. It is a useful tool for identifying the areas for implementation leadership development. Further research is needed on how, why, and when distinct types of leadership behaviors have different effects on healthcare organizations in implementation processes.

Abstract
Abstract
Objective This retrospective cohort study analyzes risk factors for abnormal pre-pregnancy body mass index and abnormal gestational weight gain in twin pregnancies.
Methods Data from 10 603/13 682 twin pregnancies were analyzed using uni- and multivariable logistic regression models to determine risk factors for abnormal body mass index and
weight gain in pregnancy.
Results Multiparity was associated with pre-existing obesity in twin pregnancies (aOR: 3.78, 95% CI: 2.71 – 5.27). Working in academic or leadership positions (aOR: 0.57, 95% CI:
0.45 – 0.72) and advanced maternal age (aOR: 0.96, 95% CI: 0.95 – 0.98) were negatively associated with maternal obesity. Advanced maternal age was associated with a lower risk for maternal
underweight (aOR: 0.95, 95% CI: 0.92 – 0.99). Unexpectedly, advanced maternal age (aOR: 0.98, 95% CI: 0.96 – 0.99) and multiparity (aOR: 0.6, 95% CI: 0.41 – 0.88) were also associated with
lower risks for high gestational weight gain. Pre-existing maternal underweight (aOR: 1.55, 95% CI: 1.07 – 2.24), overweight (aOR: 1.61, 95% CI: 1.39 – 1.86), obesity (aOR: 3.09, 95% CI:
2.62 – 3.65) and multiparity (aOR: 1.64, 95% CI: 1.23 – 2.18) were all associated with low weight gain. Women working as employees (aOR: 0.85, 95% CI: 0.73 – 0.98) or in academic or
leadership positions were less likely to have a low gestational weight gain (aOR: 0.77, 95% CI: 0.64 – 0.93).
Conclusion Risk factors for abnormal body mass index and gestational weight gain specified for twin pregnancies are relevant to identify pregnancies with increased risks for poor
maternal or neonatal outcome and to improve their counselling. Only then, targeted interventional studies in twin pregnancies which are desperately needed can be performed.

Abstract
OBJECTIVES Here we asked, whether contrast enhanced ultrasound (CEUS) enables to judge early treatment response in malignant lymphoma as a potential guidance for further treatment. METHODS From May 2017 to May 2018, 21 patients with histologically confirmed diagnosis of lymphoma were examined by B-mode ultrasound (B-US) and CEUS at fixed early time points after commencing therapy (days [d] 0, 15 and 30 after therapy start) and contrast enhancement patterns in target lymphoma lesions were quantified using Bracco-VUE Box® (DCE-US). To estimate the potential value of CEUS-enhancement patterns for early response prediction, patients were grouped according to their best achieved actual response into complete remission (CR) patients, partial remission (PR) patients or progressive disease (PD) patients. RESULTS Between d0, d15 and d30, CR-patients showed a median lymphoma shrinking by 34% in B-US. PD-patients experienced a median lymphoma size reduction by 44% on day 15, but lymphoma mass again increased by 20% between d15 and d30. In contrast, the median CEUS enhancement intensity, as assessed by the area under the curve (AUC) was increasing at d15 in CR and PD patients (CR to 152%, PD: to 126%), but decreased at d30 to 14% in CR patients and 22% in PD patients. CONCLUSIONS While early response assessment using B-US might be useful to predict treatment response in lymphoma, CEUS and DCE-US-although often feasible-do not provide additional value in this regard.

Abstract
OBJECTIVE In active early rheumatoid arthritis (RA), glucocorticoids are often used for bridging, due to the delayed action of methotrexate. We compare the effect of three bridging strategies including high-dose and low-dose prednisolone on radiographic and clinical outcomes. METHODS Adult RA patients from one rheumatology hospital and 23 rheumatology practices presenting with moderate/high disease activity were randomised (1:1:1) to 60 mg (high-dose, HDP), 10 mg prednisolone (low-dose, LDP) daily (tapered to 0 mg within 12 weeks), or placebo. The 12-week-intervention period was followed by 40 weeks of therapy at physicians' discretion. The primary outcome was radiographic change at 1 year measured by the modified Sharp/van der Heijde (mSvdH) score. Disease activity was assessed by DAS28 (ESR). RESULTS Of 395 randomized patients (n=132 HDP, n=131 LDP, n=132 placebo), 375 (95%) remained in the modified intention-to-treat analysis. Mean changes (standard deviation) in mSvdH scores of the 3 groups after one year were comparable: HDP 1.0 (2.0), LDP 1.1 (2.2), placebo 1.1 (1.5) units. The primary analysis showed no superiority of HDP vs. placebo (estimated difference of the mean change -0.04 (95% confidence interval (CI) -0.5; 0.4)). At week 12, mean DAS28 (ESR) differed: HDP vs. placebo: -0.6 (95%CI -1.0; -0.2); LDP vs. placebo: -0.8 (95% CI -1.2; -0.5). At week 52, there was no significant difference in DAS28 (ESR) between the 3 groups (range 2.6-2.8). Serious adverse events occurred similarly often. CONCLUSION Short-term glucocorticoid bridging therapy at high dose showed no benefit with regard to progression of radiographic damage at one year.

Abstract
Objective: To describe the impact of the COVID-19 pandemic-related restrictions (PR) in April and May 2020 on physical activity (PA), sedentary screen time (SST), and mental well-being (MWB) in German adolescents, and to analyze associations between these variables. Methods: The Münster District Government invited all secondary school students (aged 11-17) in the region to take part in the online survey that assessed PA, SST, and MWB. For data analysis, we calculated descriptive statistics and ran linear regression analysis. Results: 1,038 students (627 [60.4%] female; 14.18 [± 1.97] years) were included in the analysis. During the PR, a marked decline in overall PA (p < .001) and a significant increase (p < .001) in SST were observed. One-third of the students reported worrying more and being less satisfied with their lives since PR. A decrease in life satisfaction (ß = -.524, p < .001) as well as an increase in general worrying (ß = -.336, p = .015) were associated with a decrease in PA during PR. Conclusion: The results show that the restrictions led to a decrease in physical activity, which may have detrimental effects on the students' mental and physical health.

Abstract
BACKGROUND In some areas of Germany, there is a shortage of specialist physicians for patients with inflammatory rheumatic diseases. Delegating certain medical care services to qualified, specialized rheumatological assistants (SRAs) might be an effective way to supplement the available capacity for specialized medical care. METHODS Patients under stable treatment for rheumatoid arthritis (RA) or psoriatic arthritis (PsA) were included in this trial, which was designed to demonstrate, in a first step, the non-inferiority of a form of care involving delegation of physicians' tasks to SRAs (team-based care), in comparison to standard care, with respect to changes in disease activity at one year. "Non-inferiority," in this context, means either superiority or else an irrelevant extent of inferiority. In a second step, in case non-inferiority could be shown, the superiority of team-based care with respect to changes in patients' health-related quality of life would be tested as well. Disease activity was measured with the Disease Activity Score 28, and health-related quality of life with the EQ-5D-5L. This was a randomized, multicenter, rater-blinded trial with two treatment arms (team-based care and standard care). The statistical analysis was performed with mixed linear models (DRKS00015526). RESULTS From September 2018 to June 2019, 601 patients from 14 rheumatological practices and 3 outpatient rheumatological clinics in the German states of North Rhine-Westphalia and Lower Saxony were randomized to either team-based or standard care. Team-based care was found to be non-inferior to standard care with respect to changes in disease activity (adjusted difference = -0.19; 95% confidence interval [-0.36; -0.02]; p <0.001 for non-inferiority). Superiority with respect to health-related quality of life was not demonstrated (adjusted difference = 0.02 [-0.02; 0.05], p = 0.285). CONCLUSION Team-based care, with greater integration of SRAs, is just as good as standard care in important respects. Trained SRAs can effectively support rheumatologists in the care of stable patients with RA or PsA.

Abstract
Background Colon cancer (CC) is a disease of elderly patients (pts.) with a median age of 73 years (yrs.). Lack of data about the effects of adjuvant chemotherapy (ACT) is caused by underrepresentation of this clinically relevant cohort in interventional trials. We analyzed real‐world data from the German CPP registry with regard to a possible benefit of ACT in elderly (70+ yrs.) versus younger pts. (50 to <70 yrs.) taking cause‐specific deaths into account. Methods We analyzed the effect of age and ACT on overall survival (OS) and cause‐specific death of stage III pts. using Cox regression. Results In total, 1558 pts. were analyzed and follow‐up was 24.6 months. 62.6% of the elderly received ACT whereas 91.1% of younger pts. (p < 0.001). Oxaliplatin combinations were significantly less often given to older than younger pts. (38.8% vs. 88.9%; p < 0.001). Mean Charlson comorbidity score was significantly lower in pts. that received ACT (0.61) than in those without ACT (1.16; p < 0.001). ACT was an independent positive prognostic factor for cancer‐related death in elderly pts. even in pts. 75+ yrs. No significant difference in the effect of ACT could be observed between age groups (interaction: cancer‐specific death HR = 1.7948, p = 0.1079; death of other cause HR = 0.7384, p = 0.6705). Conclusion ACT was an independent positive prognostic factor for OS. There may be a cohort of elderly with less co‐morbidities who benefit from ACT.

Abstract
Background: Interventional studies on polypharmacy often fail to significantly improve patient-relevant outcomes, or confine themselves to measuring surrogate parameters. Interventions and settings are complex, with many factors affecting results. The AdAM study’s aim is to reduce hospitalization and death by requiring general practitioners (GPs) to use a computerized decision-support system (CDSS). The study will undergo a process evaluation to identify factors for successful implementation and to assess whether the intervention was implemented as intended. Objective: To evaluate our complex intervention, based on the Medical Research Council’s guideline dimensions. Research Questions: We will assess implementation (reach, fidelity, dose, tailoring) by asking: (1) Who took part in the intervention (proportion of GPs using the CDSS, proportion of patients enrolled in them)? Information on GPs’ and patients’ characteristics will also be collected. (2) How many and which medication alerts were dealt with? (3) Was the intervention implemented as intended? (4) On what days did GPs use the intervention tool? Methods: The process evaluation is part of a stepped-wedge cluster-randomized controlled trial. Characteristics of practices, GPs and patients using the CDSS will be compared with the non-participating population. CDSS log data will be analyzed to evaluate how the number of medication alerts changed between baseline and 2 months later, and to identify the kind of alerts that were dealt with. Comparison of enrolled patients on weekdays versus weekends will shed light on GPs’ use of the CDSS in the absence or presence of patients. Outcomes will be presented using descriptive statistics, and significance tests will be used to identify associations between them. We will conduct subgroup analyses, including time effects to account for software improvements. Discussion: This study protocol is the basis for conducting analyses of the quantitative process evaluation. By providing insight into how GPs conduct medication reviews, the evaluation will provide context to the trial results and support their interpretation. The evaluation relies on the proper documentation by GPs, potentially limiting its explanatory power.

Abstract
IMPORTANCE The magnitude of risk of pregnancy-related multiple sclerosis relapses, particularly severe relapses, following natalizumab cessation is unclear, as is whether this risk is reduced by pregnancy or other modifiable factors. OBJECTIVE To determine the association of early natalizumab withdrawal before or during pregnancy with risk of severe relapses and relapse-related disability. DESIGN, SETTING, AND PARTICIPANTS This prospective cohort study used data from the German Multiple Sclerosis and Pregnancy Registry, which enrolled participants between November 2006 and February 2018. Data were collected through structured telephone-administered questionnaires and review of neurologists' notes. Registry patients who stopped natalizumab treatment within the 2 years before or in the first trimester of pregnancy were included in this analysis. Data were analyzed between January and November 2021. EXPOSURES Cessation of natalizumab before pregnancy or until the first trimester. MAIN OUTCOMES AND MEASURES Severe and significant relapse-related disability was defined as at least a 2.0-point increase on the expanded disability status scale or new or worsening relapse-related ambulatory impairment. Multivariable models accounting for measures of disease severity and repeated events were used. RESULTS The cohort comprised 255 women with 274 pregnancies (mean [SD] age at pregnancy onset, 31.25 [4.27] years) who stopped natalizumab before pregnancy (n = 85; median time before last menstrual period, 14.29 weeks [IQR, 3.14-42.43 weeks]) or in the first trimester (n = 189). During pregnancy and the postpartum year, relapses were reported in 183 pregnancies (66.78%), severe relapses in 44 pregnancies (16.05%), and potentially life-threatening relapses in 3 pregnancies (1.10%). One year post partum, significant relapse-related disability was accrued in 29 pregnancies (10.58%). Relapses during pregnancy (n = 109; 39.78%) and in the postpartum period (n = 135; 49.27%) were common. Pregnancy (as a time-dependent covariate) was not associated with a reduced relapse risk (adjusted HR, 0.90; 95% CI, 0.64-1.27). Neither exclusive breastfeeding (adjusted HR, 1.34; 95% CI, 0.86-2.10) nor restarting natalizumab within 4 weeks post partum (adjusted HR, 1.06; 95% CI, 0.48-2.36) were associated with a reduced risk of early postpartum relapses 6 months after delivery. However, the relapse rate ratio during 12 months post partum was lower (0.49; 95% CI, 0.28-0.86) when natalizumab was restarted in the first 4 weeks after birth. CONCLUSIONS AND RELEVANCE This cohort study's finding suggest that 10% of women may retain clinically meaningful disability from pregnancy-related natalizumab cessation relapses 1 year post partum. This information should be shared with women on natalizumab who desire pregnancy to weigh the high risk of pregnancy-related relapses and disability to the partly uncertain risks of continuing natalizumab throughout pregnancy or switching to depleting agents before conception.

Abstract
Zusammenfassung
Hintergrund Um die Schlaganfallversorgung zu optimieren, wurden in
Deutschland in den letzten Jahren verschiedene
qualitätsfördernde Maßnahmen (qfM) in regional
unterschiedlichem Maß eingeführt. Ob sich diese
Maßnahmen über die Jahre flächendeckend etabliert
haben, ist unklar.
Methode Für die strukturbezogenen Analysen der Schlaganfallversorgung
in Deutschland wurden alle relevanten dokumentierten Schlaganfälle
(ICD-10) aus den Qualitätsberichten (QB) deutscher
Krankenhäuser und eine repräsentative Stichprobe von
Krankenversicherungsdaten (AOK) im Zeitraum von 2006 (QB)/2007 (AOK)
bis 2017 verwendet. Diese Informationen wurden u. a. durch Angaben
zu zertifizierten Stroke Units der Deutschen Schlaganfall-Gesellschaft (DSG)
und Daten zur Führung von regionalen Schlaganfall-Registern der
Arbeitsgemeinschaft Deutschsprachiger Schlaganfall-Register (ADSR)
ergänzt. Zur Verfolgung der Veränderungen des
Versor-gungsgeschehens im deutschen Bundesgebiet wurden die Daten mit
geografischen Daten (Bundesamt für Kartographie und
Geodäsie) verknüpft. Es erfolgten univariate Analysen der
Daten und eine Trend-Analyse der verschiedenen qfM im Jahresverlauf
(Konkordanzkoeffizient nach Kendall).
Ergebnisse Die QB Analysen zeigten einen Anstieg kodierter
Schlaganfälle in Krankenhäusern mit qfM um
14–20%. In 2006 wurden 80% der Schlaganfälle
(QB) in einem Krankenhaus mit min. einer qfM kodiert, in 2017 95%.
Diese Entwicklungen spiegelten sich auch in den AOK-Routinedaten wider,
wobei in 2007 89% und in 2017 97% der Patient:innen unter
mindestens einer qfM behandelt wurden. Dabei waren in 2007 bei 55%
der behandelnden Krankenhäuser qfM vorhanden, in 2017 bei
72%.
Schlussfolgerung Patient:innen werden inzwischen signifikant häufiger
in Krankenhäusern mit Spezialisierung auf die Schlaganfallversorgung
behandelt. Auch die verschiedenen qfM haben sich im Laufe der Jahre im
gesamten Bundesgebet verbreitet, jedoch existieren noch
Versorgungslücken, die geschlossen werden sollten, damit in Zukunft
alle Patient:innen qualitativ hochwertig behandelt werden
können.

Abstract
BACKGROUND Quality assurance for acute in-hospital care in Germany is based on compulsory comparisons between institutions, so-called external quality assurance (EQA). The effectiveness of EQA has not yet been adequately studied. The purpose of the QUASCH project, which is supported by the Innovation Fund of the Federal Joint Committee, is to investigate the association between EQA and health care outcomes, specifically with respect to stroke. METHODS The analyses were based on data from 379 825 patients insured by the AOK health insurance fund who were acutely admitted to a hospital because of stroke over the period 2007-2017. Data on 47 659 patients were derived from EQA documentation in the state of Hesse, in which stroke EQA had already been introduced in 2003; data on the remaining 332 166 patients were from other federal states, where 117 734 of these patients had been treated under EQA conditions. The association of EQA with mortality over the period of observation was analyzed by multivariate Cox regression, with the following covariates: age, sex, comorbidities, time period of occurrence, nursing care level, type of stroke, socio-economic deprivation in the region of origin, and treatment in a stroke unit. RESULTS Compared to treatment without EQA, mortality risk under EQA in the state of Hesse was significantly lower (hazard ratio [HR]: 0.93; 95% confidence interval: [0.92; 0.95]). The reduction in mortality risk with EQA was somewhat lower in the other federal states (HR: 0.96 [0.95; 0.97]). Treatment in a stroke unit was associated with a mortality risk that was lower still (HR: 0.86 [0.85; 0.87]). Mortality risk rose with age, comorbidities, and need for nursing care; it was lower in women and in persons whose stroke occurred in a later period. CONCLUSION Quality assurance measures are associated with lower mortality risk after stroke. The concentration of care in specially qualified institutions is associated with stronger effects than EQA alone.

Abstract
BACKGROUND Medications with an unfavorable risk-benefit profile in the elderly, and for which there are safer alternatives, are designated as potentially inappropriate medications (PIM). The RIME trial (Reduction of Potentially Inappropriate Medication in the Elderly) was based on PRISCUS, a list of PIM that was developed in 2010 for the German pharmaceuticals market. In this trial, it was studied whether special training and the PRISCUS card could lessen PIM and undesired drug-drug interactions (DDI) among elderly patients in primary care. METHODS A three-armed, cluster-randomized, controlled trial was carried out in two regions of Germany. 137 primary care practices were randomized in equal numbers to one of two intervention groups-in which either the primary care physicians alone or the entire practice team received special training-or to a control group with general instructions about medication. The primary endpoint was the percentage of patients with at least one PIM or DDI (PIM/DDI) per practice. The primary hypothesis was that at 1 year this endpoint would be more effectively lowered in the intervention groups compared to the control group. RESULTS Among 1138 patients regularly taking more than five drugs, 453 (39.8%) had at least one PIM/DDI at the beginning of the trial. The percent - ages of PIM/DDI at the beginning of the trial and 1 year later were 43.0% and 41.3% in the intervention groups and 37.0% and 37.6% in the control group. The estimated intervention effect of any intervention (69 practices) versus control (68 practices) was 2.3% (p = 0.36), while that of team training (35 practices) versus physician training (34 practices) was 4.3% (p = 0.22). CONCLUSION The interventions in the RIME trial did not significantly lower the percentage of patients with PIM or DDI.

Abstract
BACKGROUND Internet Use Disorders (IUD) cover a range of online-related behavioral addictions, which are acknowledged and strengthened by the inclusion of (online) gaming disorder in the ICD-11 by the World Health Organization. Internet-based telemedicine interventions offer the possibility to reach out for individuals with IUD where the disorder emerges, in order to enhance their motivation to change their Internet use behavior. METHODS In the course of the short-term telemedicine motivation-based intervention, adult participants took part in two webcam-based counselling sessions based on Motivational Interviewing techniques. Two weeks after the first webcam-based counselling session the second took place. Participants completed questionnaires regarding the motivation to change their Internet use behavior (iSOCRATES) and symptoms of IUD (s-IAT) at three times of measurement: t0 (pre-intervention), t1 (mid-intervention) and t2 (post-intervention). RESULTS 73 affected individuals (83.6% male, average age 35 years (SD = 12.49) took part in the whole intervention including the questionnaire-based post intervention survey (t2). Over the course of the telemedicine intervention, a significant increase in the motivation to change with regard to the own Internet use behavior as well as a significant reduction in the symptom severity of an IUD and duration of Internet use (reduction of 2 hrs/d) were shown. CONCLUSION The telemedicine pilot study shows that online-based consultation can be effective and helpful for individuals with IUD. Therefore, such a telemedicine intervention may be a suitable extension to the already existing analogous care system.

Abstract
BACKGROUND Brain-derived neurotrophic factor (BDNF) influences brain plasticity and feeding behaviour, and it has been linked to anorexia nervosa in numerous studies. Findings in mostly adult patients point to reduced serum BDNF levels in the acute stage of anorexia nervosa and rising levels with weight recovery. However, it is unclear whether this increase leads to normalization or supranormal levels, a difference that is potentially important for the etiology of anorexia nervosa and relapse. METHODS We measured serum BDNF at admission (n = 149), discharge (n = 130), 1-year follow-up (n = 116) and 2.5-year follow-up (n = 76) in adolescent female patients with anorexia nervosa hospitalized for the first time, and in healthy controls (n = 79). We analyzed associations with body mass index, eating disorder psychopathology and comorbidities. RESULTS Serum BDNF was only nominally lower at admission in patients with anorexia nervosa compared to healthy controls, but it increased continuously and reached supranormal levels at 2.5-year follow-up. BDNF was inversely associated with eating disorder psychopathology at discharge and positively associated with previous weight gain at 1-year follow-up. LIMITATIONS We compensated for attrition and batch effects using statistical measures. CONCLUSION In this largest longitudinal study to date, we found only nonsignificant reductions in BDNF in the acute stage of anorexia nervosa, possibly because of a shorter illness duration in adolescent patients. Supranormal levels of BDNF at 2.5-year follow-up could represent a pre-existing trait or a consequence of the illness. Because of the anorexigenic effect of BDNF, it might play an important predisposing role for relapse and should be explored further in studies that test causality.

Abstract
INTRODUCTION Clinically complex patients often require multiple medications. Polypharmacy is associated with inappropriate prescriptions, which may lead to negative outcomes. Few effective tools are available to help physicians optimise patient medication. This study assesses whether an electronic medication management support system (eMMa) reduces hospitalisation and mortality and improves prescription quality/safety in patients with polypharmacy. METHODS AND ANALYSIS Planned design: pragmatic, parallel cluster-randomised controlled trial; general practices as randomisation unit; patients as analysis unit. As practice recruitment was poor, we included additional data to our primary endpoint analysis for practices and quarters from October 2017 to March 2021. Since randomisation was performed in waves, final study design corresponds to a stepped-wedge design with open cohort and step-length of one quarter. SCOPE general practices, Westphalia-Lippe (Germany), caring for BARMER health fund-covered patients. POPULATION patients (≥18 years) with polypharmacy (≥5 prescriptions). SAMPLE SIZE initially, 32 patients from each of 539 practices were required for each study arm (17 200 patients/arm), but only 688 practices were randomised after 2 years of recruitment. Design change ensures that 80% power is nonetheless achieved. INTERVENTION complex intervention eMMa. FOLLOW-UP at least five quarters/cluster (practice). recruitment: practices recruited/randomised at different times; after follow-up, control group practices may access eMMa. OUTCOMES primary endpoint is all-cause mortality and hospitalisation; secondary endpoints are number of potentially inappropriate medications, cause-specific hospitalisation preceded by high-risk prescribing and medication underuse. STATISTICAL ANALYSIS primary and secondary outcomes are measured quarterly at patient level. A generalised linear mixed-effect model and repeated patient measurements are used to consider patient clusters within practices. Time and intervention group are considered fixed factors; variation between practices and patients is fitted as random effects. Intention-to-treat principle is used to analyse primary and key secondary endpoints. ETHICS AND DISSEMINATION Trial approved by Ethics Commission of North-Rhine Medical Association. Results will be disseminated through workshops, peer-reviewed publications, local and international conferences. TRIAL REGISTRATION NCT03430336.

Abstract
INTRODUCTION In May 2019, the WHO classified internet gaming disorder (IGD) as a mental disorder in the upcoming International Classification of Diseases 11th Revision. However, individuals affected by IGD or internet use disorders (IUDs) are often not provided with adequate therapy due to a lack of motivation or absence of adequate local treatment options. To close the gap between individuals with IUDs and the care system, we conduct an online-based motivational intervention to reduce problematic internet use and promote treatment motivation in internet gaming disorder and internet use disorder (OMPRIS). METHODS AND ANALYSIS Within the randomised controlled trial, a total of n=162 participants will be allocated by sequential balancing randomisation to the OMPRIS intervention or a waitlist control group. The study includes an extensive diagnostic, followed by a 4-week psychological intervention based on motivational interviewing, (internet-related) addiction therapy, behavioural therapy techniques and additional social counselling. The primary outcome is the reduction of problematic internet use measured by the Assessment of Internet and Computer Game Addiction Scale. Secondary outcomes include time spent on the internet, motivation for change (Stages of Change Readiness and Treatment Eagerness Scale for Internet Use Disorder), comorbid mental symptoms (Patient Health Questionnaire-9, Generalized Anxiety Disorder Screener-7), quality of life (EuroQoL Standardised Measure of Health-related Quality of Life-5 Dimensions, General Life Satisfaction-1), self-efficacy (General Self-Efficacy Scale), personality traits (Big Five Inventory-10), therapeutic alliance (Helping Alliance Questionnaire) and health economic costs. The diagnosis of (comorbid) mental disorders is carried out with standardised clinical interviews. The measurement will be assessed before (T0), at midpoint (T1) and after the OMPRIS intervention (T2), representing the primary endpoint. Two follow-up assessments will be conducted after 6 weeks (T3) and 6 months (T4) after the intervention. The outcomes will be analysed primarily via analysis of covariance. Both intention-to-treat and per-protocol analyses will be conducted. ETHICS AND DISSEMINATION Participants will provide written informed consent. The trial has been approved by the Ethics Committee of the Faculty of Medicine, Ruhr University Bochum (approval number 19-6779). Findings will be disseminated through presentations, peer-reviewed journals and conferences. TRIAL REGISTRATION NUMBER DRKS00019925.

Abstract
Background: As evidence concerning the impact of socioeconomic factors on the risk of peripheral artery disease (PAD) is sparse, we assessed the association of education and area-level factors (population density, type of municipality and local unemployment rate) on the onset of PAD in older adults. Patients and methods: The analysis used data of the getABI study, a prospective cohort study with seven years of follow-up. Onset of PAD was determined by ankle brachial index (<0.9) or PAD symptoms. Cox regression analysis was employed. Results: Out of 5,444 primary care attendees without PAD at baseline, there were 1,381 participants with PAD onset (cumulative observation time 31,739 years), yielding an event rate of 43.5 (0.95 confidence interval [0.95 CI] 41.2-45.8) per 1,000 person-years. Multivariable Cox regression analysis showed an association of PAD onset with low education (hazard ratio 1.29; 0.95 CI 1.14-1.46; P<0.001), high population density (0.93; 0.89-0.98; P=0.002), small cities (compared to large cities) (0.71; 0.53-0.96; P=0.027) and high local unemployment rate (1.04; 1.00-1.07; P=0.032). The impact of low education on PAD onset was higher for men (2.11; 1.64-2.72) than for women (1.22; 1.07-1.40) (interaction term P=0.013). Conclusions: Socioeconomic factors, education as well as area-level socioeconomic indicators, make independent contributions to PAD onset in older adults.

Abstract
(1) Background: Evidence has accumulated that patients with anorexia nervosa (AN) are at higher risk for vitamin D deficiency than healthy controls. In epidemiologic studies, low 25(OH) vitamin D (25(OH)D) levels were associated with depression. This study analyzed the relationship between 25(OH)D serum levels in adolescent patients and AN and depressive symptoms over the course of treatment. (2) Methods: 25(OH)D levels and depressive symptoms were analyzed in 93 adolescent (in-)patients with AN from the Anorexia Nervosa Day patient versus Inpatient (ANDI) multicenter trial at clinic admission, discharge, and 1 year follow up. Mixed regression models were used to analyze the relationship between 25(OH)D levels and depressive symptoms assessed by the Beck Depression Inventory (BDI-II). (3) Results: Although mean 25(OH)D levels constantly remained in recommended ranges (≥50 nmol/L) during AN treatment, levels decreased from (in)patient admission to 1 year follow up. Levels of 25(OH)D were neither cross-sectionally, prospectively, nor longitudinally associated with the BDI-II score. (4) Conclusions: This study did not confirm that 25(OH)D levels are associated with depressive symptoms in patients with AN. However, increasing risks of vitamin D deficiency over the course of AN treatment indicate that clinicians should monitor 25(OH)D levels.
