Abstract
During NASA's Apollo missions, inhalation of dust particles from lunar regolith was identified as a potential occupational hazard for astronauts. These fine particles adhered tightly to spacesuits and were unavoidably brought into the living areas of the spacecraft. Apollo astronauts reported that exposure to the dust caused intense respiratory and ocular irritation. This problem is a potential challenge for the Artemis Program, which aims to return humans to the Moon for extended stays in this decade. Since lunar dust is "weathered" by space radiation, solar wind, and the incessant bombardment of micrometeorites, we investigated whether treatment of lunar regolith simulants to mimic space weathering enhanced their toxicity. Two such simulants were employed in this research, Lunar Mare Simulant-1 (LMS-1), and Lunar Highlands Simulant-1 (LHS-1), which were added to cultures of human lung epithelial cells (A549) to simulate lung exposure to the dusts. In addition to pulverization, previously shown to increase dust toxicity sharply, the simulants were exposed to hydrogen gas at high temperature as a proxy for solar wind exposure. This treatment further increased the toxicity of both simulants, as measured by the disruption of mitochondrial function, and damage to DNA both in mitochondria and in the nucleus. By testing the effects of supplementing the cells with an antioxidant (N-acetylcysteine), we showed that a substantial component of this toxicity arises from free radicals. It remains to be determined to what extent the radicals arise from the dust itself, as opposed to their active generation by inflammatory processes in the treated cells.

Abstract
BACKGROUND With the aim to show the feasibility of early tumor shrinkage (ETS) concept implementation into daily clinical practice in the Czech Republic, a non-interventional, multicentric, single arm, prospective study in real world set-up was performed. MATERIAL AND METHODS The study objectives were to explore the time interval from the treatment starting date to the date of the first radiographic control (TFRC) and evaluate the proportion of patients who achieved ≥ 20% tumor regression within the first 8 weeks of first-line therapy, in the real-world settings. RESULTS The medians of TFRC in all individual participating centers were > 12 weeks (range 14.0-36.4 weeks). TFRC ≤ 8 weeks was reported for only 3% of patients in the cohort with first-line therapy, and there were only 3 patients (1%) who achieved tumor regression of ≥ 20% by day 60 (8.6 weeks). CONCLUSION These findings indicate that the basic time parameter of ETS could not realistically be employed in routine oncology care of patients with metastatic colorectal cancer (mCRC) in the Czech Republic, unless there would be a strict request to perform TRFC by week 8 since the initiation of the therapy. In addition, the frequency of objective tumor response to first-line therapy with cetuximab + chemotherapy was evaluated. Based on the relative regression in the sum of diameters of measurable metastatic lesions, unconfirmed partial responses were achieved in 42.4 % and unconfirmed complete response in 8.6% of patients, altogether corresponding to the overall response rate of 51% with first-line therapy. The frequency of responses was higher among patients with left than right sided primary tumors. It seems that the regimen of cetuximab/FOLFOX might be more active in frontline therapy of right sided RAS wild type mCRC than cetuximab/FOLFIRI.

Abstract
Three-dimensional (3D) printing of silica glass is dominated by techniques that rely on traditional particle sintering. At the nanoscale, this limits their adoption within microsystem technology, which prevents technological breakthroughs. We introduce the sinterless, two-photon polymerization 3D printing of free-form fused silica nanostructures from a polyhedral oligomeric silsesquioxane (POSS) resin. Contrary to particle-loaded sacrificial binders, our POSS resin itself constitutes a continuous silicon-oxygen molecular network that forms transparent fused silica at only 650°C. This temperature is 500°C lower than the sintering temperatures for fusing discrete silica particles to a continuum, which brings silica 3D printing below the melting points of essential microsystem materials. Simultaneously, we achieve a fourfold resolution enhancement, which enables visible light nanophotonics. By demonstrating excellent optical quality, mechanical resilience, ease of processing, and coverable size scale, our material sets a benchmark for micro- and nano-3D printing of inorganic solids.

Abstract
OBJECTIVE The diagnosis of obstructive sleep apnea (OSA) is a complex time- and resource-intensive diagnostic procedure. Since tissue inhibitors of matrix metalloproteinases (TIMP's) are involved in various pathophysiological processes and are correlated with a high cardiovascular risk, TIMP's appear to be a suitable candidate for an OSA-biomarker. PATIENTS AND METHODS In a prospective controlled diagnostic study, TIMP-1 serum levels of 273 OSA-patients and controls were analyzed for correlation with OSA severity, BMI, age, sex, cardio-/ cerebrovascular comorbidities. Furthermore, longitudinal medium- and long-term effects of CPAP-treatment (n=15) on TIMP-1-levels were investigated. RESULTS TIMP-1 was clearly linked to OSA as well as to disease severity (mild, moderate, severe; each p<0.001) and was not influenced by age, gender, BMI, or cardio-/cerebrovascular comorbidities. ROC curve analysis revealed an AUC of 0.91 ± 0.017 SE (p<0.001), suggesting a TIMP-1 cut-off value of 75 ng/ml (sensitivity 0.78; specificity 0.91) being especially sensitive for patients with severe OSA (sensitivity 0.89; specificity 0.91). The likelihood ratio was 8.88, while the diagnostic odds ratio was 37.14. CPAP-treatment led to a significant decrease of TIMP-1 after 6-8 months (p=0.008). CONCLUSIONS TIMP-1 seems to fulfill the preconditions for a circulating OSA-biomarker: disease-specific with a mandatory presence in affected patients, reversible on treatment, reflects disease severity and provides a cutoff value between the healthy state and disease. In the clinical routine, TIMP 1 may help to stratify the individual OSA-associated cardiovascular risk and to monitor the treatment response to CPAP-therapy as a further step towards providing a personalized therapy.

Abstract
SARS CoV 2 S-glycoproteins play a crucial role in the entry steps of viral particles. Due to their surface location, they are the main target for host immune responses and the focus of most vaccine strategies. The D614G mutation identified in late January became dominant during March 2020, rendering SARS-CoV-2 more infectious. In April 2020, the Alpha, Beta and Gamma variants emerged simultaneously in Asia, South Africa, and South America, respectively. They were 1.6 to 2 times more transmissible than the ancestral strain. The currently dominant Omicron variant (BA.2) is not a direct descendant from the D614G lineage, but rather emerged from the BA.1 variant (as did BA.4 and BA.5). It is substantially different from all the other variants. It presents significantly reduced susceptibility to antibody neutralization: after 2 doses of mRNA-vaccine, neutralizing titers to Omicron are 41 to 84 times lower than neutralization titers to D614G. That said, a booster dose of mRNA-vaccine increases Omicron neutralization titers and reduces the risk of severe infection.

Abstract
During the SARS CoV-2 primary infection, the neutralizing antibodies focused against the spike (S) glycoproteins are responsible for blockage of virus-host cell interaction. The cellular response mediated by CD4+ and CD8+ T-cells is responsible for control of viremia. Immune memory against SARS-CoV-2 depends on virus type, replication kinetics and route of penetration. The formation and persistence of germinal centers are critical for the generation of affinity-matured plasma cells and memory B cells capable of mediating durable immunity. They can persist up to 30 weeks after vaccination and several months after infection. Heterogeneity in the longevity of the vaccination-induced GC response is significant.

Abstract
Modern patient-centered and cost-efficient care concepts in hospitals require the mapping of multidisciplinary process chains into clinical pathways. Clinical decision support systems and operations research methods use algorithms to classify patients into homogeneous groups and to model a complete clinical pathway for scheduling individual procedures. An improvement of the economic situation of the care facility can be achieved through improved resource utilization, reduced patient waiting times and a shortening of the length of stay. The interdisciplinary use of centrally stored interoperable information and comprehensive care management via information technology (IT) services lay the foundation for the dissolution of traditional IT system architectures in medicine and the development of flexibly integrable modern system platforms. New IT approaches such as the semantically standardized definition of procedures and resource properties, the use of clinical decision support systems and the use of service-oriented system architectures form the basis for the deep integration of radiology services into comprehensive interdisciplinary care concepts.

Abstract
Introduction: Teaching is considered a mentally challenging occupation. Teacher self-efficacy is a personal resource which buffers the experience of stress and may be important in maintaining mental health. The preventive intervention "Manual-Based Psychological Group Program for Teachers" (MBPGPT) was applied and evaluated state-wide to improve the mental health of teachers. This study aims to investigate the intricate relation between teacher self-efficacy and mental health and their changes in the course of the intervention. Method: Using a single-group pre-/post-design, the relation between teacher self-efficacy and mental health was investigated in 742 teachers. Pre- and post-changes in teacher self-efficacy and their interaction with mental health were examined in a subsample of 171 teachers, who met the conservative inclusion criteria. In ancillary analyses, correlations with underlying changes in work-related behavior and experience patterns were analyzed to better understand the intricate link between teacher self-efficacy and mental health. Results: Teacher self-efficacy showed a significant, moderate correlation with mental health. Self-efficacy was moderately higher after the intervention than before the intervention, but independent of changes in mental health. Teacher self-efficacy was related to work-related psychological resistance and positive emotions. An increase in teacher self-efficacy was accompanied by an improvement in life satisfaction and distancing ability. A decrease in teacher self-efficacy went hand in hand with reduced experience of social support. Discussion: This study confirmed teacher self-efficacy as an important, reliable resource and its correlation with psychological resistance. The absence of a control group limits what causal conclusions can be drawn from the study. Nevertheless, self-efficacy seems to be a worthwhile goal of preventive interventions for teachers and should be promoted due to its wide-ranging implications. Suggestions for further studies and interventions are made.

Abstract
Measuring circulating progesterone (P4) of dairy cows is a key component of many research studies dealing with basic and applied reproduction physiology. The gold standard in dairy cows for the measurement of P4 in serum is radioimmunoassay (RIA), but it generates radioactive waste and requires licensed facilities. The purpose of this study was to develop and validate an in-house competitive enzyme immunoassay (EIA) to measure the P4 concentration in serum of dairy cattle. The secondary objective was to validate a commercial EIA. In the present study, a competitive EIA was developed using commercially available antibodies and conjugates. Ninety-six well microtiter plates were coated with the secondary antibody and incubated overnight. Following a washing step, the wells were blocked using the primary antibody. Serum samples were prepared by first extracting P4 using petroleum ether, then diluted in working conjugate solution. Samples were pipetted into the coated and blocked plates, then the matching HRP conjugate label (P4-3-HRP, East Coast Bio, North Berwick, ME) was added. The plates were incubated for 2 h, then washed. The substrate solution was added, and the plate was incubated up to 1 h at room temperature in the dark until a blue color had developed. A stop solution was added, and the optical density measured on a microplate reader was set at 450 nm. The binding proportion was calculated by a visible spectrum absorbance reader, and the amount of P4 was calculated using a log-logit regression line. The commercial EIA was executed as suggested by the manufacturer. The validation of the in-house EIA was done by calculating the inter- and intraassay coefficients of variation (CV) and evaluating the parallelism of diluted samples. The results from the in-house and commercial EIA were also compared with the ones from the RIA graphically (scatterplots and Bland-Altman plots) and statistically, using the Spearman correlation coefficient (r) and the Cohen's kappa statistics using a threshold of 1.0 ng/mL (κ). For the in-house EIA, the intraassay CV were all <10%, but the interassay for samples with small and large P4 concentration had CV of 12.5 and 11.0%, respectively. The correlations between the results from the EIA and the RIA were strong (in-house: r = 0.90; commercial: r = 0.83). At small concentrations (<1.0 ng/mL), however, the correlation with the gold standard was weak (in-house: r = 0.27; commercial: r = 0.14). This was likely due to the lack of accuracy at small concentrations, also shown by the absence of parallelism in samples ≤0.4 ng/mL. In conclusion, results from both the in-house and commercial EIA strongly correlated with the gold standard, but less so at smaller concentrations. The in-house EIA offers good accuracy to measure P4 in samples with a concentration >0.4 ng/mL, and a perfect agreement with RIA using a threshold of 1.0 ng/mL.

Abstract
Cross-enterprise electronic patient records are a key element in the design of interoperable medical care networks and process chains. However, the different requirements concerning type, performance and quality assurance of available communication services within the different healthcare sectors still require that the hospitals participate in various secure communication networks which have to be bridged for cross-sectoral communication. Cross-institutional pathways for telemedicine, however, can be mapped both within and across sectoral boundaries via automated process chains using the IHE (Integrating the Healthcare Enterprise) defined integration profile CrossEnterprise Document Sharing (XDS) and associated integration profiles. The provision of medical documents in a cross-institutional patient record outside of defined medical pathways requires differentiated authorization management. In this respect, consent documents according to the IHE APPC (Advanced Patient Privacy Consents) profile enable the documentation of the patient's consent, including information about planned authorized people, document types, period and type of document access allowed. Providing access control to medical documentation by the patients themselves is an essential part of the required focusing of medical services on patients. New interoperability standards optimized for use on mobile devices, such as FHIR (Fast Healthcare Interoperability Resources), will enable simplified delivery of patient-centered health records and other medical services on mobile platforms in the future.

Abstract
Delayed natural killer (NK) cell reconstitution after allogeneic stem cell transplantation (alloSCT) is associated with a higher risk of developing invasive aspergillosis. The interaction of NK cells with the human pathogen Aspergillus (A.) fumigatus is mediated by the fungal recognition receptor CD56, which is relocated to the fungal interface after contact. Blocking of CD56 signaling inhibits the fungal mediated chemokine secretion of MIP-1α, MIP-1β, and RANTES and reduces cell activation, indicating a functional role of CD56 in fungal recognition. We collected peripheral blood from recipients of an allograft at defined time points after alloSCT (day 60, 90, 120, 180). NK cells were isolated, directly challenged with live A. fumigatus germ tubes, and cell function was analyzed and compared to healthy age and gender-matched individuals. After alloSCT, NK cells displayed a higher percentage of CD56brightCD16dim cells throughout the time of blood collection. However, CD56 binding and relocalization to the fungal contact side were decreased. We were able to correlate this deficiency to the administration of corticosteroid therapy that further negatively influenced the secretion of MIP-1α, MIP-1β, and RANTES. As a consequence, the treatment of healthy NK cells ex vivo with corticosteroids abrogated chemokine secretion measured by multiplex immunoassay. Furthermore, we analyzed NK cells regarding their actin cytoskeleton by Structured Illumination Microscopy (SIM) and flow cytometry and demonstrate an actin dysfunction of NK cells shown by reduced F-actin content after fungal co-cultivation early after alloSCT. This dysfunction remains until 180 days post-alloSCT, concluding that further actin-dependent cellular processes may be negatively influenced after alloSCT. To investigate the molecular pathomechansism, we compared CD56 receptor mobility on the plasma membrane of healthy and alloSCT primary NK cells by single-molecule tracking. The results were very robust and reproducible between tested conditions which point to a different molecular mechanism and emphasize the importance of proper CD56 mobility.

Abstract
Background The adequate allocation of inpatient care resources requires assumptions about the need for health care and how this need will be met. However, in current practice, these assumptions are often based on outdated methods (e.g. Hill-Burton Formula). This study evaluated floating catchment area (FCA) methods, which have been applied as measures of spatial accessibility, focusing on their ability to predict the need for health care in the inpatient sector in Germany. Methods We tested three FCA methods (enhanced (E2SFCA), modified (M2SFCA) and integrated (iFCA)) for their accuracy in predicting hospital visits regarding six medical diagnoses (atrial flutter/fibrillation, heart failure, femoral fracture, gonarthrosis, stroke, and epilepsy) on national level in Germany. We further used the closest provider approach for benchmark purposes. The predicted visits were compared with the actual visits for all six diagnoses using a correlation analysis and a maximum error from the actual visits of ± 5%, ± 10% and ± 15%. Results The analysis of 229 million distances between hospitals and population locations revealed a high and significant correlation of predicted with actual visits for all three FCA methods across all six diagnoses up to ρ = 0.79 (p < 0.001). Overall, all FCA methods showed a substantially higher correlation with actual hospital visits compared to the closest provider approach (up to ρ = 0.51; p < 0.001). Allowing a 5% error of the absolute values, the analysis revealed up to 13.4% correctly predicted hospital visits using the FCA methods (15% error: up to 32.5% correctly predicted hospital). Finally, the potential of the FCA methods could be revealed by using the actual hospital visits as the measure of hospital attractiveness, which returned very strong correlations with the actual hospital visits up to ρ = 0.99 (p < 0.001). Conclusion We were able to demonstrate the impact of FCA measures regarding the prediction of hospital visits in non-emergency settings, and their superiority over commonly used methods (i.e. closest provider). However, hospital beds were inadequate as the measure of hospital attractiveness resulting in low accuracy of predicted hospital visits. More reliable measures must be integrated within the proposed methods. Still, this study strengthens the possibilities of FCA methods in health care planning beyond their original application in measuring spatial accessibility.

Abstract
BACKGROUND Computed tomography (CT) is the gold standard of body composition analysis at the tissue-organ level. The present study aimed to determine the impact of CT-defined sarcopenia and myosteatosis on outcomes, including overall survival, unplanned hospital admissions and related costs, in patients who had completed treatment of curative intent for head and neck cancer (HNC). METHODS Retrospective observational study of patients undergoing radiotherapy of curative intent ± other treatment modalities for HNC. Tissue density data derived at the third lumbar vertebra (L3) were evaluated with sarcopenia defined per sex-specific published threshold values for skeletal muscle index, stratified by body mass index and mean skeletal muscle attenuation in HU (Hounsfield units). RESULTS Pre- or post-treatment images were available for 79/98 patients (80.6%) and 61/98 patients (62.2%), respectively. Sarcopenia was present in 42/79 patients pre-treatment and 36/61 patients post-treatment, whereas myosteatosis was present in 63/79 patients pre-treatment and 48/61 patients post-treatment. In patients with pre- and post-treatment images (n = 60), the median (range) percentage weight change was -8.5% (-29.9 to +11.7). On multivariable analysis, a post-treatment sarcopenia hazard ratio of 3.87 (95% confidence interval = 1.22-12.24, P = 0.021) and a pre-treatment myosteatosis hazard ratio of 8.86 (95% confidence interval = 1.12-69.88, P = 0.038) were independent predictors of reduced overall survival. There was no difference in radiotherapy or chemotherapy treatment completion based on pre-treatment sarcopenia status. The mean (SD) difference unplanned hospital admission cost was $15 846 ($17 707) for patients without sarcopenia versus $47 945 ($82 688) for patients with sarcopenia at any time point (P = 0.077). CONCLUSIONS As CT-defined sarcopenia and myosteatosis hold clinically meaningful prognostic value, muscle status evaluation is recommended in routine clinical practice.

Abstract
Positron emission tomography (PET) and prompt gamma (PG) detection are promising proton therapy monitoring modalities. Fast calculation of the expected distributions is desirable for comparison to measurements and to develop/train algorithms for automatic treatment error detection. A filtering formalism was used for positron-emitter predictions and adapted to allow for its use for the beamline of any proton therapy centre. A novel approach based on a filtering formalism was developed for the prediction of energy-resolved PG distributions for arbitrary tissues. The method estimates PG yields and their energy spectra in the entire treatment field. Both approaches were implemented in a research version of the RayStation treatment planning system. The method was validated against PET monitoring data and Monte Carlo simulations for four patients treated with scanned proton beams. Longitudinal shifts between profiles from analytical and Monte Carlo calculations were within -1.7 and 0.9 mm, with maximum standard deviation of 0.9 mm and 1.1 mm, for positron-emitters and PG shifts, respectively. Normalized mean absolute errors were within 1.2 and 5.3%. When comparing measured and predicted PET data, the same more complex case yielded an average shift of 3 mm, while all other cases were below absolute average shifts of 1.1 mm. Normalized mean absolute errors were below 7.2% for all cases. A novel solution to predict positron-emitter and PG distributions in a treatment planning system is proposed, enabling calculation times of only a few seconds to minutes for entire patient cases, which is suitable for integration in daily clinical routine.

Abstract
AbstractBackground.Treatment with low-dose interferon alpha (IFN-α) is often associated with neuropsychiatric side effects. In addition to depression and anxiety, IFN-α associated cognitive impairment significantly affects patient’s mental health and quality of life.Aims of the study.To measure possible effects of low-dose IFN-α on cognitive functioning and its relationship to the development of depression and anxiety.Method.We prospectively followed 38 patients with a chronic hepatitis B or C by neuropsychological tests and psychiatric self-rating scales during 12 weeks of low-dose treatment with IFN-α.Results.Before IFN-α treatment, neuropsychological tests as well as self-ratings in the Beck’s Depression Inventory (BDI), the Hospital Anxiety and Depression Scale (HADS) and the Self-Report Symptom Inventory 90 Items-Revised (SCL-90-R) were within the normal range. Following 12 weeks of treatment with IFN-α resulted in a slight, but significant increase in depression scores. Neuropsychological assessment after 12 weeks of IFN-α treatment showed a significant decrease of the immediate recall in the Auditory-Verbal Learning Test (AVLT) and a significant reduction of words recited in the Controlled Oral Word Association Test (COWA). Cognitive impairment did not significantly correlate with depressive symptoms or anxiety.Conclusion.Our results indicate that even low-dose IFN-α induces cognitive impairment independent from depressive symptoms, which might be related to functional disturbances in the prefrontal cortex and the hippocampus. We suggest close monitoring of cognitive function during IFN-α treatment of chronic hepatitis.

Abstract
In vivo verification of light ion therapy based on positron-emission tomography (PET) imaging of irradiation induced patient activation relies on activity predictions from Monte-Carlo (MC) or analytical computational engines for comparison to the measurements. In order to achieve the necessary accuracy, experimental data are indispensable for the validation of the calculation models. For this we irradiated thick reference targets with mono-energetic helium, carbon and oxygen ion beams and measured the resulting material activation offline with a commercial full-ring PET/CT scanner located nearby the treatment room. Acquired PET data were analysed over time to separate the activity contribution of different radionuclides. Determined production yields were compared to published findings obtained from in-beam activation measurements with a limited-angle double-head PET camera. In addition, we investigated the time-dependence of the measured radionuclide-specific contributions and of the distal activity range, as well as the lateral spread of the activity signal as a function of beam penetration depth. We present radionuclide-specific depth-resolved activity distributions and production yields for the radionuclides [Formula: see text], [Formula: see text] and [Formula: see text], dominating irradiation-induced patient activation. We observe systematically lower production yields with a ratio between the dual-head and our full-ring PET measurements of, on average, 1.7 and 1.3 for the oxygen and carbon beam irradiations, and 1.7 (2.1) for the high (low) energy helium beam irradiations. Findings on the temporal development of the activity range confirm the expectation, with the oxygen beam induced signal being the most sensitive scenario. The experimental data reported in this work, acquired with a state-of-the-art full ring PET scanner, provide a comprehensive and consistent basis for the benchmarking of PET signal calculation engines. In particular, they can support a fine-tuning of the underlying physics models used by the respective implementation and therefore improve the accuracy of PET-based therapy verifications at current and future treatment facilities.

Abstract
Invasive aspergillosis (IA) is a life-threatening complication among allogeneic hematopoietic stem cell transplant (alloSCT) recipients. Despite well known risk factors and different available assays, diagnosis of invasive aspergillosis remains challenging. 103 clinical variables from patients with hematological malignancies and subsequent alloSCT were collected. Associations between collected variables and patients with (n = 36) and without IA (n = 36) were investigated by applying univariate and multivariable logistic regression. The predictive power of the final model was tested in an independent patient cohort (23 IA cases and 25 control patients). Findings were investigated further by in vitro studies, which analysed the effect of etanercept on A. fumigatus-stimulated macrophages at the gene expression and cytokine secretion. Additionally, the release of C-X-C motif chemokine ligand 10 (CXCL10) in patient sera was studied. Low monocyte concentration (p = 4.8 × 10−06), severe GvHD of the gut (grade 2–4) (p = 1.08 × 10−02) and etanercept treatment of GvHD (p = 3.5 × 10−03) were significantly associated with IA. Our studies showed that etanercept lowers CXCL10 concentrations in vitro and ex vivo and down-regulates genes involved in immune responses and TNF-alpha signaling. Our study offers clinicians new information regarding risk factors for IA including low monocyte counts and administration of etanercept. After necessary validation, such information may be used for decision making regarding antifungal prophylaxis or closely monitoring patients at risk.

Abstract
Aims The intestinal microbiota of newborn calves is largely unexplored even if it is of great significance for their future health. Therefore, the aim of the study was to gain a better insight into the development dynamics of certain bacterial groups during the first week of life. Methods and Results Faecal samples of healthy Simmental calves (dual‐purpose breed; n = 80), bottle fed and raised in a dairy farm were taken immediately after birth and at 6/12/24/48/72/168 h (h) after birth. Samples were analysed using cultural, biochemical and molecular–biological methods. The aerobe, anaerobe, Enterobacteriaceae and Enterococcus counts of healthy calves increased significantly between 6 and 24 h postpartum (P <0·05). Apart from the anaerobes, bacterial counts decreased after reaching a plateau at 24–48 h. Enterococcus faecalis was detected in significantly higher counts compared to E. faecium (P <0·05). Lactobacilli developed more slowly and increased until day 7 after birth to a mean value of 6·8 × 107 CFU per g. MALDI‐TOF analysis of 2338 lactobacilli isolates resulted in 36 different species. Conclusions Lactobacillus reuteri became the most common Lactobacillus sp. during the first week of life. Significance and Impact of the Study This fact seems to be very important for the calf’s intestinal health because L. reuteri is known to show in vitro bactericidal effects against bacterial pathogens and anti‐infective activities against rotaviruses and Cryptosporidium parvum.

Abstract
In 2016, an extraordinary burial of a young adult individual was discovered at the Late Pre-Pottery Neolithic B (LPPNB, 7,500–6,900 BCE) settlement of Baʻja in southern Jordan. This burial has exceptional grave goods and an elaborate grave construction. It suggests discussing anew reconstructions of early Neolithic social structures. In this article, we will summarize former theories on the emergence of leadership and hierarchies and present a multivariate model according to which anthropological and archaeological data of the burial will be analyzed. In conclusion, we surmise that early Neolithic hierarchization in southern Jordan was based on corporate pathways to power rather than self-interested aggrandizers. However, some aspects of the burial point to regional exchange networks of prestige goods, a trait considered characteristic of network based leadership. In line with anthropological and sociological research, we argue that pathways to power should be considered as relational processes that can be understood only when comparing traits of the outstanding person to her/his social environment.

Abstract
UNLABELLED Previously independent living older people suffering fractures of the hip have a high risk of new admission to a nursing home during the subsequent months. This study shows that older people admitted to hospital for fractures of the pelvis and spine have a similar risk of admission to a nursing home. INTRODUCTION Fall-related fractures are a serious threat to the health and well-being of older persons. Long-term consequences of hip fractures such as institutionalization and mortality are well-known. The impact of other fragility fractures is less well-understood. The aim of this study was to estimate risks of institutionalization and death for different fragility fractures and compare them with the corresponding risks after hip fracture. METHODS Data was retrieved from a German health insurance company. Between 2005 and 2008 more than 56,000 community-dwelling people with a hospital admission or discharge diagnosis of a fracture of the femur, spine, pelvis, proximal humerus, distal radius, tibia, or fibula were included. Crude and age-adjusted 6-month incidence rates for institutionalization and death were calculated. To compare the risks of institutionalization or mortality of non-hip fractures with the risk after hip fracture, multivariate regression models were applied. RESULTS Crude institutionalization rates and mortality were highest in patients with hip fracture. However, after adjustment for age, functional status, and comorbidity, risks of institutionalization after fractures of pelvis (relative risk (RR), 0.94; 95% confidence interval (CI) 0.86; 1.02 in women and 0.89; 95% CI 0.70; 1.12 in men), and spine (RR, 0.95; 95% CI 0.87; 1.03 in women and 0.91; 95% CI 0.76; 1.08 in men) were not statistically different compared to the risk after hip fracture. CONCLUSIONS The risk of institutionalization after fractures of the spine and pelvis was similar to the risk after hip fracture. These fracture sites seem to be associated with a significant decline in physical function.

Abstract
While fractures around the knee are known to be rare, physicians have encountered a rise in the frequency due to the increased participation of children and adolescents in high-impact sports at a younger age. Even if the treatment of fractures in some cases resembles that in adults, the diagnostics and treatment in childhood and adolescence require a hígh level of experience in order avoid possible sequelae and to enable early recognition. Thorough diagnostics using clinical and imaging investigations as well as a precise weighing up of the treatment are essential to minimize differences in leg length and axial malpositioning of the leg. A decision between conservative and operative treatment is made for both the femur and tibia depending on the type of fracture. Decisive is the degree of dislocation of the fracture. In operative treatment, the axis conform reduction and subsequent stress stable treatment are particularly decisive. Avulsion trauma, bony avulsions of the intercondylar eminence and patellar injuries are also treated conservatively with immobilization or surgically with the aid of various fixation techniques, depending on the degree of dislocation.

Abstract
BACKGROUND The aetiology of dementia is not yet fully understood. Stress can have a damaging effect on brain health. The prognostic effect of anxiety is still unclear regarding Alzheimer's disease as well as vascular dementia.AimsTo explore the association between anxiety and future dementia. METHOD Medline, PsycINFO, CINAHL, Web of Science and ALOIS were searched for publications up to 12 January 2018. Longitudinal studies with a follow-up of at least 2 years were included, if the trait or state anxiety had been assessed at baseline. Studies with cognitive impairment at baseline were not included. We used a random effects model to calculate the pooled time to Alzheimer's disease and incidence of vascular dementia. RESULTS Anxiety predicts risk of Alzheimer's disease (n = 26 193 out of seven studies, hazard ratio1.53, 95% CI 1.16-2.01, P < 0.01) and vascular dementia (n = 4916 out of two studies, odds ratio1.88, 95% CI 1.05-3.36, P < 0.01). The pooled hazard ratio regarding risk of Alzheimer's disease was still significant when excluding studies with critical risk of bias (n = 14 110 out of six studies, hazard ratio 1.35, 95% CI 1.08-1.70, P < 0.01). CONCLUSIONS Anxiety is a risk factor for both types of dementia. The temporal and functional relation between anxiety and dementia needs investigation in future studies. The protective value of treating anxiety should be explored further.Declaration of interestNone.

Abstract
Objective To identify changes in work-related psychological attitudes that influence mental health improvement in school teachers after participation in a psychological group program. Methods In an exploratory study with N = 544 matched cases we combined a screening instrument for general mental health (GHQ) with measures of work-related behavioral and experiential patterns (AVEM). We compared four GHQ change types pre and post intervention with regard to their performance on eleven sub-scales that figure as professional resources. Factors that showed significant relative changes and thus (likely) contributed to improved health status were identified by means of pairwise t-tests and corresponding effect sizes. Results Decreases in willingness to work to exhaustion (VB), in striving for perfection (PS), and in the tendency for resignation in the face of failure (RT), as well as an increase of distancing ability (DF) and of inner calm and balance (IR) appear to be the main factors influencing health improvement in the intervention. Simultaneously, an increase of satisfaction with life (LZ) is observed. Conclusions The balanced use of professional resources is a critical ingredient in maintaining teachers' health. Adjusting the balance between commitment and resistance through factors found in this analysis help teachers in maintaining and strengthening resilience. The coaching program addresses these factors by focusing on personal attitudes and good interpersonal relationships in the school environment.

Abstract
The new developments of the FLUKA Positron-Emission-Tomography (PET) tools are detailed. FLUKA is a fully integrated Monte Carlo (MC) particle transport code, used for an extended range of applications, including Medical Physics. Recently, it provided the medical community with dedicated simulation tools for clinical applications, including the PET simulation package. PET is a well-established imaging technique in nuclear medicine, and a promising method for clinical in vivo treatment verification in hadrontherapy. The application of clinically established PET scanners to new irradiation environments such as hadrontherapy requires further experimental and theoretical research to which MC simulations could be applied. The FLUKA PET tools, besides featuring PET scanner models in its library, allow the configuration of new PET prototypes via the FLUKA Graphical User Interface (GUI) Flair. Both the beam time structure and scan time can be specified by the user, reproducing PET acquisitions in time, in a particle therapy scenario. Furthermore, different scoring routines allow the analysis of single and coincident events, and identification of parent isotopes generating annihilation events. Two reconstruction codes are currently supported: the Filtered Back-Projection (FBP) and Maximum-Likelihood Expectation Maximization (MLEM), the latter embedded in the tools. Compatibility with other reconstruction frameworks is also possible. The FLUKA PET tools package has been successfully tested for different detectors and scenarios, including conventional functional PET applications and in beam PET, either using radioactive sources, or simulating hadron beam irradiations. The results obtained so far confirm the FLUKA PET tools suitability to perform PET simulations in R&D environment.

Abstract
Endosalpingiosis of the urinary bladder is a rare benign condition characterised by the presence of ectopic endosalpingeal tissue in the bladder. If histology shows two or more Müllerian-derived components, this condition is referred to as Müllerianosis.To our knowledge less than 20 cases of Müllerianosis and 5 cases of endosalpingiosis have been documented in the literature.Although the pathogenesis remains unclear, two theories exist. The implantation theory assumes that Müllerian-derived tissue gets implanted in the wall of the urinary bladder during pelvic surgery. The second theory proposes a metaplastic origin of the disease.Patients suffering from endosalpingiosis or Müllerianosis may present with symptoms such as suprapubic pain, frequent urination, dysuria or gross haematuria, possibly with a cyclical appearance.We present the case of a 40-year-old female patient, who primarily presented with painful haematuria and was diagnosed with endosalpingiosis and treated by transurethral resection. Also we review the current literature.

Abstract
BACKGROUND Epidermolysis bullosa acquisita (EBA) is a complex autoimmune bullous disease disease with variable clinical presentations and multiple possible diagnostic tests, making an international consensus on the diagnosis of EBA essential. OBJECTIVES To obtain an international consensus on the clinical and diagnostic criteria for EBA. METHODS The International Bullous Diseases Group (IBDG) met three times to discuss the clinical and diagnostic criteria for EBA. For the final voting exercise, 22 experts from 14 different countries voted on 50 different items. When > 30% disagreed with a proposal, a discussion was held and re-voting carried out. RESULTS In total, 48 of 50 proposals achieved consensus after discussion. This included nine diagnostic criteria, which are summarized in a flow chart. The IBDG was unable to determine one procedure that would be applicable worldwide. A limitation of the study is that differential diagnosis of bullous systemic lupus erythematosus has not been addressed. CONCLUSIONS This first international consensus conference established generally agreed-upon clinical and laboratory criteria defining the clinical classification of and diagnostic testing for EBA. Holding these voting exercises in person with the possibility of discussion prior to voting has advantages in reaching consensus over Delphi exercises with remote voting.

Abstract
Shewanella spp. are Gram-negative, rod-shaped, motile bacteria that are widely distributed in marine and freshwater environments. The bacteria are present in the physiological microflora of fish from temperate waters and are known as fish spoilage species. From clinically healthy fish and from fish with skin ulcerations, Shewanella spp. is regularly isolated, indicating a possible role as fish pathogen. In this study, 74 isolates of Shewanella spp. were analysed. For species identification, biochemical techniques, 16S rRNA sequencing, MALDI-TOF MS and the Sherlock Microbial Identification System (MIS) based on the composition of fatty acid ethyl esters were compared. The phylogenetic relationship, cytotoxicity in vitro and resistance against antibiotics were tested. The most reliable method for species identification was 16S rRNA sequencing. From diseased fish, clinically healthy fish and the aquatic environment, different Shewanella species were isolated. This indicates that Shewanella spp. is widespread in the aquatic milieu and acts as a secondary pathogen. The virulence of Shewanella spp. is probably not depending on the species but on the isolate itself. Many isolates of Shewanella spp. were showing multiresistances against antibiotic substances, especially in samples derived from retailers and in routine diagnostics, all Shewanella spp. should therefore be tested for resistances against antibiotic agents.

Abstract
At the time of primary therapy (surgery, systemic chemotherapy and/or radiation), disseminated tumor cells in the bone marrow can be found in almost one-third of patients with cancer of the breast, ovary, esophagus, stomach, colon, and other solid tumors. Whereas the prognostic impact of the mere presence of these cells is still a matter of debate, it has been shown that expression of tumor-associated antigens in disseminated tumor cells is linked to more aggressive disease. Therefore, further characterization of disseminated tumor cells at the protein and gene level has become increasingly important. To date, the most common detection method for disseminated tumor cells in the bone marrow is an immunocytochemical approach using cytokeratin-directed antibodies for detection of epithelial cells and the APAAP system for their visualization. We have established a new double immunofluorescence technique enabling simultaneous detection, phenotyping, and antigen quantification of disseminated tumor cells. Mononuclear cells from bone marrow are enriched by Ficoll gradient centrifugation and cytospins are prepared. Double immunofluorescence is performed using antibodies against cytokeratins 8/18/19 (mAb A45B/B3) and the uPA receptor CD87 (pAb HU277). CD87 expression is recorded by confocal laser scanning microscopy (CLSM) using fluorescence labeled latex beads as the reference; staining intensities of all the scans are then summed and quantified (extended focus). This protocol, originally designed for disseminated tumor cells in bone marrow, can also be applied to disseminated tumor cells in blood, to leukapheresis cells or to cells present in malignant ascites or other malignant effusions. The tumor cells detected may be used for gene and mRNA analyses. Furthermore, disseminated tumor cells also represent interesting targets for clinical studies on patient prognosis or prediction of therapy response as well as for specific tumor-biological therapies.
