Abstract
BACKGROUND Interprofessional training wards (ITW) are increasingly being integrated into teaching and training concepts in visceral surgery clinics. OBJECTIVE How safe is patient care on an ITW in visceral surgery? MATERIAL AND METHODS Data collection took place from November 2021 to December 2022. In this nonrandomized prospective evaluation study the frequency and severity of adverse events (AE) in 3 groups of 100 patients each in a tertiary referral center hospital for visceral surgery were investigated. The groups consisted of patients on the ITW and on the conventional ward before and after implementation of the ITW. The Global Trigger Tool (GTT) was used to search for AE. Simultaneously, a survey of the treatment was conducted according to the Picker method to measure patient reported outcome. RESULTS Baseline characteristics and clinical outcome parameters of the patients in the three groups were comparable. The GTT analysis found 74 nonpreventable and 5 preventable AE in 63 (21%) of the patients and 12 AE occurred before the hospital stay. During the hospital stay 50 AE occurred in the operating theater and 17 on the conventional ward. None of the five preventable AE (in 1.7% of the patients) was caused by the treatment on the ITW. Patients rated the safety on the ITW better than in 90% of the hospitals included in the Picker benchmark cohort and as good as on the normal ward. CONCLUSION The GTT-based data as well as from the patients' point of view show that patient care on a carefully implemented ITW in visceral surgery is safe.

Abstract
Schistosoma reflexum (SR) is a lethal congenital syndrome characterized by U-shaped dorsal retroflexion of the spine and exposure of abdominal viscera. SR is usually associated with severe dystocia. The syndrome is thought to be inherited as a Mendelian trait. We collected a series of 23 SR-affected calves from four breeds (20 Holstein, one Red Danish, one Limousin, one Romagnola) and performed whole-genome sequencing (WGS). WGS was performed on 51 cattle, including 14 cases with parents (trio-based; Group 1) and nine single cases (solo-based; Group 2). Sequencing-based genome-wide association studies with 20 Holstein cases and 154 controls showed no association (above Bonferroni threshold; P-value<3 ×10-09). Assuming a monogenic recessive inheritance, no region of shared homozygosity was observed, suggesting heterogeneity. Alternatively, the presence of possible dominant acting de novo mutations were assessed. In Group 1, heterozygous private variants, absent in both parents, were found in seven cases. These involved the ACTL6A, FLNA, GLG1, IQSEC2, MAST3, MBTPS2, and MLLT1 genes. In addition, heterozygous private variants affecting the genes DYNC1LI1, PPP2R2B, SCAF8, SUGP1, and UBP1 were identified in five cases from Group 2. The detected frameshift and missense variants are predicted to cause haploinsufficiency. Each of these 12 affected genes belong to the class of haploinsufficient loss-of-function genes or are involved in embryonic and pre-weaning lethality or are known to be associated with severe malformation syndromes in humans and/or mice. This study presents for the first time a detailed genomic evaluation of bovine SR, suggesting that independent de novo mutations may explain the sporadic occurrence of SR in cattle.

Abstract
Silicon photonic ring resonator thermometers have been shown to provide temperature measurements with a 10 mK accuracy. In this work we identify and quantify the intrinsic on-chip impairments that may limit further improvement in temperature measurement accuracy. The impairments arise from optically induced changes in the waveguide effective index, and from back-reflections and scattering at defects and interfaces inside the ring cavity and along the path between light source and detector. These impairments are characterized for 220 × 500 nm Si waveguide rings by experimental measurement in a calibrated temperature bath and by phenomenological models of ring response. At different optical power levels both positive and negative light induced resonance shifts are observed. For a ring with L = 100 µm cavity length, the self-heating induced resonance red shift can alter the temperature reading by 200 mK at 1 mW incident power, while a small blue shift is observed below 100 µW. The effect of self-heating is shown to be effectively suppressed by choosing longer ring cavities. Scattering and back-reflections often produce split and distorted resonance line shapes. Although these distortions can vary with resonance order, they are almost completely invariant with temperature for a given resonance and do not lead to measurement errors in themselves. The effect of line shape distortions can largely be mitigated by tracking only selected resonance orders with negligible shape distortion, and by measuring the resonance minimum wavelength directly, rather than attempting to fit the entire resonance line shape. The results demonstrate the temperature error due to these impairments can be limited to below the 3 mK level through appropriate design choices and measurement procedures.

Abstract
BACKGROUND Colonization of near-patient surfaces in hospitals plays an important role as a source of healthcare-associated infections. Routine disinfection methods only result in short-term elimination of pathogens. AIM To investigate the efficiency of a newly developed antimicrobial coating containing nanosilver in long-term reduction of bacterial burden in hospital surfaces to close the gap between routine disinfection cycles. METHODS In this prospective, double-blinded trial, frequently touched surfaces of a routinely used treatment room in an emergency unit of a level-I hospital were treated with a surface coating (nanosilver/DCOIT-coated surface, NCS) containing nanosilver particles and another organic biocidal agent (4,5-dichloro-2-octyl-4-isothiazolin-3-one, DCOIT), whereas surfaces of another room were treated with a coating missing both the nanosilver- and DCOIT-containing ingredient and served as control. Bacterial contamination of the surfaces was examined using contact plates and liquid-based swabs daily for a total trial duration of 90 days. After incubation, total microbial counts and species were assessed. FINDINGS In a total of 2880 antimicrobial samples, a significant reduction of the overall bacterial load was observed in the NCS room (median: 0.31 cfu/cm2; interquartile range: 0.00-1.13) compared with the control coated surfaces (0.69 cfu/cm2; 0.06-2.00; P < 0.001). The nanosilver- and DCOIT-containing surface coating reduced the relative risk of a critical bacterial load (defined as >5 cfu/cm2) by 60% (odds ratio 0.38, P < 0.001). No significant difference in species distribution was detected between NCS and control group. CONCLUSION Nanosilver-/DCOIT-containing surface coating has shown efficiency for sustainable reduction of bacterial load of frequently touched surfaces in a clinical setting.

Abstract
There is widespread consensus that there is no indication for postoperative antibiotic administration after elective surgery. However, medial thigh lift (MTL) remains a procedure with a notoriously high rate of wound-healing disorders and infections. This study investigates the correlation between prolonged antibiotic administration and complications after MTL in massive weight loss patients. We performed a single-institution retrospective review of 121 patients undergoing MTL between 2009 and 2020. Data on postoperative outcome, demography, surgery and comorbidities were collected. All patients received intravenous antibiotics preoperatively. One group was continued on oral antibiotics for two weeks postoperatively. Complications and surgical site infections were observed and evaluated. There was no difference between the groups regarding age, BMI, or presence of obesity-associated risk factors. We observed complications in 76 patients (71%), with 60 (56%) minor and 16 (15%) major complications. The group without prolonged antibiotic administration had a higher number of total complications (OR 3.5; p = 0.0037), major complications (OR 4; p = 0.01), and wound infections (OR 6.8; p = 0.0004). Logistical regression analysis showed that this effect was independent of type of weight loss, resection volume, and age. Reduction of major infections by prolonged antibiotics was, however, dependent on BMI Δ. No side-effects associated with antibiotics were registered in this series. This study suggests that prolonged antibiotic administration may decrease complications in MTL. We thus continue to use prolonged antibiotic administration after MTL. Further research is needed to determine the optimal duration of antibiotic treatment. Level of Evidence: Level IV: therapeutic study.

Abstract
Recently, Artificial Intelligence namely Deep Learning methods have revolutionized a wide range of domains and applications. Besides, Digital Pathology has so far played a major role in the diagnosis and the prognosis of tumors. However, the characteristics of the Whole Slide Images namely the gigapixel size, high resolution and the shortage of richly labeled samples have hindered the efficiency of classical Machine Learning methods. That goes without saying that traditional methods are poor in generalization to different tasks and data contents. Regarding the success of Deep learning when dealing with Large Scale applications, we have resorted to the use of such models for histopathological image segmentation tasks. First, we review and compare the classical UNet and Att-UNet models for colon cancer WSI segmentation in a sparsely annotated data scenario. Then, we introduce novel enhanced models of the Att-UNet where different schemes are proposed for the skip connections and spatial attention gates positions in the network. In fact, spatial attention gates assist the training process and enable the model to avoid irrelevant feature learning. Alternating the presence of such modules namely in our Alter-AttUNet model adds robustness and ensures better image segmentation results. In order to cope with the lack of richly annotated data in our AiCOLO colon cancer dataset, we suggest the use of a multi-step training strategy that also deals with the WSI sparse annotations and unbalanced class issues. All proposed methods outperform state-of-the-art approaches but Alter-AttUNet generates the best compromise between accurate results and light network. The model achieves 95.88% accuracy with our sparse AiCOLO colon cancer datasets. Finally, to evaluate and validate our proposed architectures we resort to publicly available WSI data: the NCT-CRC-HE-100K, the CRC-5000 and the Warwick colon cancer histopathological dataset. Respective accuracies of 99.65%, 99.73% and 79.03% were reached. A comparison with state-of-art approaches is established to view and compare the key solutions for histopathological image segmentation.

Abstract
Background In the SARS-CoV-2 pandemic, general and specialist Palliative Care (PC) plays an essential role in health care, contributing to symptom control, psycho-social support, and providing support in complex decision making. Numbers of COVID-19 related deaths have recently increased demanding more palliative care input. Also, the pandemic impacts on palliative care for non-COVID-19 patients. Strategies on the care for seriously ill and dying people in pandemic times are lacking. Therefore, the program ‘Palliative care in Pandemics’ (PallPan) aims to develop and consent a national pandemic plan for the care of seriously ill and dying adults and their informal carers in pandemics including (a) guidance for generalist and specialist palliative care of patients with and without SARS-CoV-2 infections on the micro, meso and macro level, (b) collection and development of information material for an online platform, and (c) identification of variables and research questions on palliative care in pandemics for the national pandemic cohort network (NAPKON). Methods Mixed-methods project including ten work packages conducting (online) surveys and qualitative interviews to explore and describe i) experiences and burden of patients (with/without SARS-CoV-2 infection) and their relatives, ii) experiences, challenges and potential solutions of health care professionals, stakeholders and decision makers during the SARS-CoV-2 pandemic. The work package results inform the development of a consensus-based guidance. In addition, best practice examples and relevant literature will be collected and variables for data collection identified. Discussion For a future “pandemic preparedness” national and international recommendations and concepts for the care of severely ill and dying people are necessary considering both generalist and specialist palliative care in the home care and inpatient setting.

Abstract
INTRODUCTION Clinical symptoms are mostly unspecific in hepatic diseases, thus most clinical examinations are of limited benefit in the diagnosis of hepatic diseases and often only general statements can be made about parenchymal damage or loss of function. In contrast, sonography of the liver can provide information about the type of lesion and thus also about the prognosis for the animal. A systematic assessment of organ size, parenchymal, vascular and bile duct system structures can facilitate to make possible findings. Sonography is also used in further diagnostics such as liver biopsy or chole-cystocentesis. This review describes the basic procedure for the sonographic examination in ruminants and camelids on the basis of selected findings relevant to the clinical veterinarian. In addition, potential and limits of additional diagnostics are discussed.

Abstract
BACKGROUND AND OBJECTIVE Telemedical stroke networks improve stroke care and provide access to time-dependent acute stroke treatment in predominantly rural regions. The aim is a presentation of data on its utility and regional distribution. METHODS The working group on telemedical stroke care of the German Stroke Society performed a survey study among all telestroke networks. RESULTS Currently, 22 telemedical stroke networks including 43 centers (per network: median 1.5, interquartile range, IQR, 1-3) as well as 225 cooperating hospitals (per network: median 9, IQR 4-17) operate in Germany and contribute to acute stroke care delivery to 48 million people. In 2018, 38,211 teleconsultations (per network: median 1340, IQR 319-2758) were performed. The thrombolysis rate was 14.1% (95% confidence interval 13.6-14.7%) and transfer for thrombectomy was initiated in 7.9% (95% confidence interval 7.5-8.4%) of ischemic stroke patients. Financial reimbursement differs regionally with compensation for telemedical stroke care in only three federal states. CONCLUSION Telemedical stroke care is utilized in about 1 out of 10 stroke patients in Germany. Telemedical stroke networks achieve similar rates of thrombolysis and transfer for thrombectomy compared with neurological stroke units and contribute to stroke care in rural regions. Standardization of network structures, financial assurance and uniform quality measurements may further strengthen the importance of telestroke networks in the future.

Abstract
BACKGROUND This study investigates the correlation between the Edmonton Obesity Staging System (EOSS) and the occurrence of postoperative complications after medial thigh lift in formerly obese patients. PATIENTS AND METHODS A single-institution retrospective review of patients undergoing medial thigh lift between 2009 and 2019 after massive weight loss. Data on demography, comorbidities, surgery, and postoperative outcome were extracted from patients' charts. Patients were grouped into EOSS categories. Complications were classified into minor and major. Logistic regression analysis was performed to determine the association between risk factors and complications. RESULTS One hundred and eight patients were included in the study. Complications occurred in 76 (70%) of the patients, most of which were minor (60/108, 56%). Complications increased with increasing EOSS stage, and all EOSS 3 patients had complications. Classification as EOSS 2 or 3 significantly associated with occurrence of postoperative complications (OR 99.3, p<0.001) as well as minor and major complications individually (OR 3.1 and 6.5, p<0.05). This effect was independent of body mass index (BMI), maximum BMI loss, type of weight loss, volume of liposuction, weight of resected tissue, and type of surgery. CONCLUSION EOSS is a robust and independent predictor for postoperative complications in medial thigh lift surgery after massive weight loss.

Abstract
INTRODUCTION Renal cysts are fluid-filled cavities with an epithelial lining that, depending on their size, can cause clinical symptoms and thus require conservative or surgical therapy. Nephrectomy is primarily used in cattle for simple kidney cysts while sclerotherapy is well established in humans and individual case reports have been published in small animal medicine. This case report describes the first successful treatment of a solitary, perirenal cyst using a right-sided laparotomy and intraluminal instillation of 96% ethanol solution in a Swiss Fleckvieh cow. Diagnostics, surgical procedures and aftercare are descripted and risks are compared to other methods. Sclerotherapy is an organ-preserving alternative to nephrectomy that is suitable for buiatric practice, the methodology should be confirmed in subsequent intervention studies.

Abstract
OBJECTIVE This study evaluated whether the consumption of a cereal bar combining different phytoestrogens could contribute to the reduction of climacteric symptoms in women. METHODS This is a clinical, prospective, randomized, simple-blind trial. Forty-eight women, aged 40-65 years, with climacteric symptoms, from a city in southwestern Paraná, Brazil. Participants were randomly assigned into two groups; Phytoestrogens group (PHY = 24), which received for 90-day period a cereal bar containing 80.73 milligrams of soybean and flaxseed phytoestrogens, and the placebo group (PLA = 24), which consumed rice flakes biscuit. Clinical, sociodemographic and anthropometric data were collected and climacteric symptoms were assessed using the Kupperman Index (KI). RESULTS Forty-three women were analyzed (PHY = 21 and PLA = 22). There were significant reductions in the overall KI score in both groups at the end of the intervention period (p < 0.05). However, the comparison between the groups using linear regression models presented expressively better symptom improvement in the PHY group -6.43 over time (95% CI: -11.6; -1.26; p < 0.05) KI points, with perimenopausal -15.15 (95% CI: -28.95; -1.35) and postmenopausal women -19.34 (95% CI: -33.68; -4.99) showed considerably greater reductions in symptoms at the end of the intervention period compared to premenopausal women. There was also significant reduction in symptoms of hot flushes, paresthesia, sexual complaints, insomnia and melancholy. CONCLUSION The consumption of a cereal bar containing phytoestrogens was able to improve the symptoms of climacteric syndrome.

Abstract
Objectives: Nationwide prevention programs in Germany aim to promote oral health. The group prevention program starts in kindergarten and ends when the children are about 12 y old. While in a recent study, toothbrushing behavior of 12-y-old children was analyzed, the present study’s objective was to examine the children’s ability to achieve oral cleanliness and to analyze how toothbrushing behavior and compliance with the toothbrushing recommendations taught in the group prevention programs predict oral cleanliness. Methods: Twelve-year-old randomly selected children (N = 174) were asked to brush their teeth to the best of their abilities, and simultaneously a video was recorded for behavioral analyses. Plaque levels were measured before and immediately after toothbrushing. In addition, dental status and gingival bleeding were assessed. Results: After brushing to the best of their abilities, there was plaque on 50% (±24.72%) of all measured sites at the gingival margin (Marginal Plaque Index). Regression analyses revealed approximately 22% of the variance of marginal plaque on the outer surfaces to be explained by the time brushed by circular movements (β = −0.41;P < 0.001) and the number of sextants brushed for at least 7.5 s (β = −0.171; P < 0.05). Circular movements explained most additional variance (ΔR2 = 0.113; P < 0.001). With respect to inner surfaces, none of the behavioral aspects explained any variance of oral cleanliness. Conclusion: Despite regular group prevention measures, 12-y-old children show limited skills to clean their teeth adequately. Furthermore, none of the recommended behaviors relates to oral cleanliness after toothbrushing at inner surfaces. As a consequence, it is necessary to explore further which behavioral sequences effectively improve oral cleanliness. Knowledge Transfer Statement: This study illustrates that children’s compliance to toothbrushing recommendations is not necessarily related to toothbrushing effectiveness. Clinicians should therefore assess the effectivity of recommendations individually and provide individual guidance for improvement.

Abstract
Infection with hepatitis B virus (HBV) often leads to development of chronic liver disease. In fact, 10% of infected adults and almost 90% of infected infants develop chronic hepatitis B associated with severe liver diseases, including acute liver failure, liver cirrhosis or hepatocellular carcinoma. At present there is no effective cure for chronic hepatitis B. The current treatment of chronically infected patients is long-term, expensive and relies on treatment with nucleos(t)ide analogs in combination with immune therapies, that frequently lead to adverse side effects. Recently, the National Institute of Health proposed strategic plan for Trans-NIH research to cure hepatitis B. The key priority is better understanding of HBV life cycle and its interactions with host cell. Due to the fact that HBV is a small double stranded DNA virus encoding only a limited number of proteins, HBV replication widely relies on host cell pathways and proteins. As demonstrated by numerous reports, HBV core protein (HBc) which is the main component of viral nucleocapsid, plays multiple roles in HBV life cycle and is engaged in many protein interaction networks of the host cell. Several recent studies have shown that HBV proteins can be modified by different types of posttranslational modifications (PTMs) that affect their protein-protein interactions, subcellular localization and function. In this review, we discuss diverse PTMs of HBc and their role in regulation of HBc function in the context of HBV replication and pathogenesis. Keywords: hepatitis B virus; posttranslational modifications; HBV core protein; phosphorylation; ubiquitination; arginine methylation.

Abstract
BACKGROUND Epidural analgesia provides sufficient analgesia during labor but can cause hypotension despite various prophylactic measures. We studied its effects on pre-placental, fetoplacental, and fetal hemodynamics using Doppler ultrasound. The primary endpoint was the pulsatility index of the umbilical artery at 30 min after establishing epidural analgesia. Secondary endpoints included maternal blood pressures and neonatal outcome data. METHODS We included healthy parturients at a cervical dilation ≥2 cm, with or without a request for epidural analgesia (n=32 per group). Ultrasound studies of the uterine arteries, umbilical artery and fetal middle cerebral artery were performed before insertion of the epidural catheter, and 30, 60 and 90 min after; the same time-points were assessed in the non-epidural control group. Maternal blood pressure was measured by a continuous non-invasive arterial pressure monitor. RESULTS Ultrasound studies detected no significant differences in pulsatility indices over time in any blood vessel. In contrast to the control group, maternal blood pressures were significantly lower for all measures after the onset of analgesia compared with baseline values (mean systolic pressure decreased from 132.7 ± 15.9 mmHg to 123.1 ± 14.4 mmHg at 30 min, P=0.003). The mean pH value of the umbilical arterial blood was 7.29 (±0.06) in the epidural group versus 7.31 (±0.08) in the control group (P=0.33). The median Apgar score at 5 min was 10 in both groups. CONCLUSIONS Pre-placental, fetoplacental and fetal hemodynamics remained stable despite a statistically significant decrease in maternal blood pressure in laboring parturients receiving epidural analgesia.

Abstract
INTRODUCTION Most studies of elderly-onset Crohn's disease [CD; diagnosed in patients aged 60 or over] have described a mild course. However, data on the natural history of perianal fistulising CD [pfCD] in this population are scarce. In a population-based cohort study, we described the prevalence, natural history, and treatment of pfCD in patients with elderly-onset CD vs patients with paediatric-onset CD. METHOD All patients diagnosed with CD at or after the age of 60 between 1988 and 2006, were included [n = 372]. Logistic regression, Cox models, and a nested case-control method were used to identify factors associated with pfCD. RESULTS A total of 34 elderly patients [9% of the 372] had pfCD at diagnosis. After a median follow-up of 6 years (interquartile range [IQR]: 3; 10), 59 patients [16%] had pfCD; the same prevalence [16%] was observed in paediatric-onset patients. At last follow-up, anal incontinence was more frequent in elderly patients with pfCD than in elderly patients without pfCD [22% vs 4%, respectively; p < 10-4]. Rectal CD at diagnosis was associated with pfCD: hazard ratio (95% confidence interval [CI] = 2.8 [1.6-5.0]). Although 37% of the patients received immunosuppressants and 17% received anti-tumour necrosis factor agents, 24% [14 out of 59] had a definitive stoma at last follow-up. CONCLUSION During the first 6 years of disease, the prevalence of pfCD was similar in elderly and paediatric patients. Rectal involvement was associated with the appearance of pfCD in elderly-onset patients. Around a quarter of patients with elderly-onset CD will have a stoma. Our results suggest that treatment with biologics should be evaluated in these patients.

Abstract
Rosellinia (Xylariaceae) is a large, cosmopolitan genus comprising over 130 species that have been defined based mainly on the morphology of their sexual morphs. The genus comprises both lignicolous and saprotrophic species that are frequently isolated as endophytes from healthy host plants, and important plant pathogens. In order to evaluate the utility of molecular phylogeny and secondary metabolite profiling to achieve a better basis for their classification, a set of strains was selected for a multi-locus phylogeny inferred from a combination of the sequences of the internal transcribed spacer region (ITS), the large subunit (LSU) of the nuclear rDNA, beta-tubulin (TUB2) and the second largest subunit of the RNA polymerase II (RPB2). Concurrently, various strains were surveyed for production of secondary metabolites. Metabolite profiling relied on methods with high performance liquid chromatography with diode array and mass spectrometric detection (HPLC-DAD/MS) as well as preparative isolation of the major components after re-fermentation followed by structure elucidation using nuclear magnetic resonance (NMR) spectroscopy and high resolution mass spectrometry (HR-MS). Two new and nine known isopimarane diterpenoids were identified during our mycochemical studies of two selected Dematophora strains and the metabolites were tested for biological activity. In addition, the nematicidal cyclodepsipeptide PF1022 A was purified and identified from a culture of Rosellinia corticium, which is the first time that this endophyte-derived drug precursor has been identified unambiguously from an ascospore-derived isolate of a Rosellinia species. While the results of this first HPLC profiling were largely inconclusive regarding the utility of secondary metabolites as genus-specific chemotaxonomic markers, the phylogeny clearly showed that species featuring a dematophora-like asexual morph were included in a well-defined clade, for which the genus Dematophora is resurrected. Dematophora now comprises all previously known important plant pathogens in the genus such as D. arcuata, D. bunodes, D. necatrix and D. pepo, while Rosellinia s. str. comprises those species that are known to have a geniculosporium-like or nodulisporium-like asexual morph, or where the asexual morph remains unknown. The extensive morphological studies of L.E. Petrini served as a basis to transfer several further species from Rosellinia to Dematophora, based on the morphology of their asexual morphs. However, most species of Rosellinia and allies still need to be recollected in fresh state, cultured, and studied for their morphology and their phylogenetic affinities before the infrageneric relationships can be clarified.

Abstract
The introduction of new therapeutic agents has revolutionized the treatment of metastatic melanoma. The approval of adjuvant anti-programmed death-1 monotherapy with nivolumab or pembrolizumab, and dabrafenib plus trametinib has recently set a new landmark in the treatment of stage III melanoma. Now, clinical trials have shown that immune checkpoint blockade can be performed in a neoadjuvant setting, an approach established as a standard therapeutic approach for other tumour entities such as breast cancer. Recent studies suggest that a pathological response achieved by neoadjuvant immunotherapy is associated with long-term tumour control and that short neoadjuvant application of checkpoint inhibitors may be superior to adjuvant therapy. Most recently, neoadjuvant ipilimumab plus nivolumab in stage III melanoma was reported. With two courses of dose-optimized ipilimumab (1 mg kg-1 ) combined with nivolumab (3 mg kg-1 ), pathological responses were observed in 77% of patients, while only 20% of patients experienced grade 3 or 4 adverse events. However, the neoadjuvant trials employing combined immune checkpoint blockade conducted so far have excluded patients with in transit metastases, a common finding in stage III melanoma. Here we report four patients with in transit metastases or an advanced primary tumour who have been treated with neoadjuvant ipilimumab plus nivolumab according to the OpACIN-neo trial scheme (arm B). All patients achieved radiological disease control and a pathological response. None of the patients has relapsed so far. Linked Comment: Blankenstein and van Akkooi. Br J Dermatol 2020; 183:421-422.

To evaluate by speckle tracking echocardiography (STE), LAGS and other myocardial deformation indices changes after transarterial valve implantation (TAVI) for severe isolated aortic stenosis (AS) in relation to the outcome measures.

Of 995 pts who underwent TAVI at our Institution between 2017–18, 120 (age = 82.8±7.7 years, 74% female, AVAi = 0.37±0.09 cm2/m2, LVEF = 61.6±11.3%, no > than 2+ mitral or aortic regurgitation, all in NSR) underwent 2-D echocardiography and STE, pre (21±34 days) and post (16±27 days) TAVI. LAGS was measured at QRS onset, and LV global longitudinal strain (LVGS) and RV free wall strain were recorded. The velocity index = peak vel LVOT/AV. Phillips IE 33 scanners (frame rates 60–80 Hz) were used and one observer analyzed data on QLAB software. The median follow-up was 208 days (range 20–763). The outcome variable was a composite of death, atrial fibrillation and hospitalization for heart failure (MACE). Univariate and multivariable logistic regression were used to determine independent predictors of LA, LV and RV free wall global strain changes (covariates; age, sex, BSA, LVEF, systolic blood pressure, LA volume index) and, separately, for predictors of MACE (covariates; age, sex, AVA index, LVEF and E/e'). Intra- and interclass correlation coefficients (ICC) were calculated.
Results
The intra- and inter-observer ICC was 0.70–0.90 and 0.90–0.95, respectively. In the absence of LA volume change, LAGS improved post TAVI in 54% of pts. Overall, mean change was 2.2±11.6% (95% CI; 0.05, 4.3) and it was significantly associated in multivariable analysis with RV free wall strain (OR=2.7, 95% CI; 1.2, 6), velocity index (OR=0.4, 95% CI; 0.2, 1), LVEF (OR= 0.3, 95% CI; 0.2, 0.8) and LVGS (OR=3.8, 95% CI; 1.4, 10), yielding together an AUC of 0.90. LVGS improved in 64% of pts by −2.8±7.5%, (95% CI: −4.2, −1.5) and the velocity index independently predicted the LVGS change (OR = 0.6; 95% CI: 0.4, 0.9). The other deformation indices did not significantly change. At follow-up, there were 6 hospitalizations for heart failure, 5 atrial fibrillation events and 6 deaths. At multivariable logistic regression analysis, post TAVI LAGS was the only variable independently predicting MACE (OR (in units of 1%) = 0.90, 95% CI; 0.82, 0.98), estimating that a 1% increase in post-LAGS decreases the likelihood of MACE by 10%.
Conclusions
1. There was no relationship between LA systolic volume and LAGS change after TAVI. 2. Within a month after the procedure, LAGS improves in less than half of pts and is directly associated with both ventricles systolic function and AS severity. 3. At a median of 9 months after TAVI, post procedural LAGS is an independent predictor of MACE and could be used in the risk stratification of such pts.

Abstract
Abstract
Introduction
Cardiac computed tomography (CT) is an established modality for planning TAVI procedures.
We validated CT parameters measured by automated software analysis and by newly trained readers against expert readers.
Methods
Consecutive patients with symptomatic severe aortic valve stenosis referred for CT assessment of the aortic root prior to TAVI were included in this analysis. Measurements were performed manually by an expert reader, a newly trained reader as well as semi-automatically using a commercially available workstation. Manual measurements were performed as per clinical standard. For semi-automatic analysis, CT data sets were exported to a dedicated workstation with fully automated detection of the aortic annulus plane.
Results
Out of 159 consecutive patients, 146 patients were included in this analysis (83+10 years). The median annulus area for expert reader, newly trained reader and software measurement was 468 mm2, 511 mm2 and 513 mm2, respectively (p=0.28) whereas the mean annulus diameter showed a mean±SD of 25.6±2 mm, 25.5±2 mm and 25.6±2 mm, respectively, p=0.47. Agreement between expert and newly trained reader for annulus area was good with Bland-Altman analysis showing a systematic overestimation of the annulus area for the newly trained reader of 16 mm2 (95% limits of agreement 42 to −74 mm2) and for automatic software of 20 mm2 (95% limits of agreement 60 to −99 mm2). Assuming an annulus area-based recommendation for a balloon-expandable Sapien 3 prosthesis (23, 26 or 29 mm prosthesis), kappa statistics revealed moderate agreement between expert measurement, newly trained reader and software measurement (κ 0.60 for newly trained reader, κ 0.58 for software measurement, p<0.0001 for all). The time needed for annulus adjustment measurement for the newly trained reader compared to software measurement was 2±0.6 minutes vs. 1±0.5 minutes, respectively, p<0.0001). The software correctly identified the annulus plane without reader correction in 49% of cases and in 51% of cases manual correction of the cusp insertion point or annular tracing had to be performed. Agreement between expert predicted angulation and software predicted angulation was excellent in 55%, good in 29% vs. 31%, moderate in 11% vs. 6% and fair in 5% vs. 8% for LAO/RAO orientation, CAU/CRA orientation, respectively (assuming excellent agreement when difference: <5°, good agreement: 5–10°, moderate agreement: 10–15° and fair agreement: >15°).
Conclusion
Novice human interpretation manually and with semi-automatic assessment of the aortic root for planning TAVI procedures is feasible with good agreement with expert measurement for annulus dimensions and prediction of implantation angles, however with a trend for systematic overestimation of the annulus area. For semi-automatic assessment, reader correction of cusp insertion point and annular dimensions have to corrected for in 50% of cases

Abstract
Abstract
Background
Fibroblast activation protein (FAP) is a serine protease that is upregulated in sites of tissue remodeling, including arthritis, tumors and atherosclerosis. We have reported that FAP degrades type I collagen in human thin-cap fibroatheromata; its expression is enhanced in advanced human plaques and induced by inflammation. However, the role of endogenous FAP in atherosclerosis remains unknown.
Purpose
To investigate the effects of constitutive Fap loss-of-function on atherosclerotic plaque formation and vulnerability.
Methods and results
Male 8-week-old Apoe−/− Fap+/+ and Apoe−/− Fap−/− mice were fed a high-cholesterol diet (1.25% chol) for 12 weeks. En face analyses of thoracoabdominal aortae using Oil Red O (ORO) revealed decreased plaques in Apoe−/− Fap−/− mice (5.7±0.5%; n=21) compared to Apoe−/− Fap+/+ mice (10.7±0.7%; n=24; p<0.0001). In parallel, ORO analyses of serial aortic root cross sections showed diminished plaques in Fap-deficient mice (18.4±3.4% vs 27.6±2.1%). As a surrogate of plaque vulnerability, fibrous cap thickness was increased in Apoe−/− Fap−/− mice (65±6 mm vs 35±3 mm; p<0.01), whereas necrotic core size, plaque macrophages (CD68) and T cells (CD3) accumulation, as well as VCAM1 expression did not differ. These changes were independent of plasma triglycerides, total and LDL-cholesterol levels. Plasma of Fap-deficient mice showed decreased FAP activity compared to Fap wildtype controls. Notably, second harmonics generation in cross sections of aortic root plaques showed that the deposition and density of fibrillar collagens was enhanced in Fap-deficient (25.5±4.4%) compared to control plaques (13.8±2.5%; p<0.05). Consistently, Fap deletion led to an accumulation of uncleaved pre-COL3A1, a proteolytic target of FAP.
Conclusions
Constitutive Fap deletion decreases experimental atherosclerosis and features of plaque vulnerability. Thus, inhibition of FAP expression or activity may be a promising therapeutic target in atherosclerosis.

Abstract
Abstract
Metal-plastic hybrids have a lot of advantages compared to purely metal or purely plastic parts. A good design for metal-plastic hybrids can help to save weight, for example in automotive applications. Therefore, it is important to understand the joining mechanisms between both materials. Aluminum AlSi9Cu3(Fe) and polyamide 6.6 with 35 % glass fibers were used as joining partners. The materials were joined by enclosing the metal part at least partially with plastic right inside the injection molding tool. Afterwards, the tensile strength of the metal-plastic hybrids was tested under a quasi-static load. This article provides a short overview of publications related to this topic, and compares their conclusions with our own results. The focus is on the influence of the surface treatment on the metal part (shot-peening) and also the effects of different joining geometries within the bonding area. Statements made in other publications were able to be confirmed and expanded for shot-peened surfaces and particular joining geometries. In most cases, shot-peening the surface of metal parts is advantageous for the joining strength. If the strength of the bond is not important, but, instead, the achievable displacement is, a shot-peened surface is not always advantageous. In addition, the joining geometries have a large influence on the behavior of the part under static load.

Abstract
The regiochemistry of four bis-Mallory photocyclization substrates has been examined from experimental and computational perspectives. Formation of all three possible regioisomers was only observed in the reaction of one of the substrates. In the other three substrates, only the two C2-symmetric products, but not the C1 product, were formed. In the three reactions that only formed two products, the photocyclization temperature could be used to select for exclusive formation of one or the other regioisomer. The use of temperature to select between two regioisomers also worked in the photocyclization of the substrate that formed three products. However, no temperature was located for exclusive formation of the third component, one of the C2-symmetric products, which always formed alongside either one or both of its regioisomers. B3LYP/6-311+G(2d,p) calculations were used to determine the energies of all of the dihydrophenanthrene (DHP), tetrahydrophenanthrene (THP), and mono-Mallory photocyclization intermediates. The oscillator strengths of the DHP precursors to the helicene products were a factor of 4.8-9.2 smaller than those of competitively formed DHPs. This observation suggests that establishment of a photostationary state is responsible for the preferential formation of helicenes that has been observed as a unique and useful feature of many Mallory photocyclizations.

Abstract
BACKGROUND Entry of human immunodeficiency virus type 1 (HIV-1) in target cells is enabled by CD4 receptor and one of two co-receptors, CXCR4 or CCR5. Deletion of 32 bp in CCR5 gene (CCR5Δ32) in both alleles provides strong but not absolute resistance to HIV-1 infection and deletion in one allele slows disease progression to AIDS. Here, we analyzed the prevalence and the role of CCR5Δ32 heterozygosity on the disease progression in HIV positive patients in the Czech Republic. PATIENTS AND METHODS A total of 92 HIV-1 seropositive subjects that included 80 Czech individuals from the AIDS center in the Hospital Na Bulovce in Prague were enrolled in CCR5 genotyping as a part of a study of the role of HIV fitness on disease progression. DNA was extracted from patient’s peripheral blood mononuclear cells and subjected to real-time PCR with specific probes detecting wild-type and 32 bp-deleted CCR5 variants. A subgroup of 74 antiretroviral therapy-naive patients with more than one year of follow-up was used to determine the role of the CCR5Δ32 heterozygous phenotype in disease progression. RESULTS CCR5Δ32 was found heterozygous in 23.8% of 80 Czech HIV-1 seropositive individuals which is very similar to 21% and 24% prevalence reported in HIV negative Czech population. Homozygous mutant variant was not detected. In CCR5Δ32 heterozygous group we observed slightly higher mean CD4+ T-cell count and lower mean plasma viremia levels. CONCLUSIONS Overall, our study indicates no obvious benefit of CCR5Δ32 heterozygosity on HIV transmission and only small benefit on disease progression in the Czech HIV-1 cohort.

Abstract
Microwave SQUID multiplexing has become a key technology for reading out large arrays of X-ray and gamma-ray microcalorimeters with mux factors of 100 or more. The desire for fast X-ray pulses that accommodate photon counting rates of hundreds or thousands of counts per second per sensor drives system design toward high sensor current slew rate. Typically, readout of high current slew rate events is accomplished by increasing the sampling rate, such that rates of order 1MHz may be necessary for some experiments. In our microwave multiplexed readout scheme, the effective sampling rate is set by the frequency of the flux-ramp modulation (f r) used to linearize the SQUID response. The maximum current slew rate between samples is then nominally Φ 0 f r/2M in (where M in is the input coupling) because it is generally not possible to distinguish phase shifts of > π from negative phase shifts of < -π. However, during a pulse, we know which direction the current ought to be slewing, and this makes it possible to reconstruct a pulse where the magnitude of the phase shift between samples is > π. We describe a practical algorithm to identify and reconstruct pulses that exceed this nominal slew rate limit on the rising edge. Using pulses produced by X-ray transition-edge sensors, we find that the pulse reconstruction has a negligible impact on energy resolution compared to arrival time effects induced by under-sampling the rising edge. This technique can increase the effective slew rate limit by more than a factor of two, thereby either reducing the resonator bandwidth required or extending the energy range of measurable photons. The extra margin could also be used to improve crosstalk or to decrease readout noise.

Abstract
In a prospective study we investigated the visual acuity and differential light sensitivity in 39 patients (40 eyes) with reattached macula. One group, treated with an encircling band (21 eyes), was compared to another, where vitrectomy and silicone oil injection had been necessary (19 eyes). Intraoperatively 9 of the vitrectomized eyes received an infusion of daunomycin (7.5 mg/l for 10 min). On average the vitrectomized eyes had a greater loss of visual acuity and differential light sensitivity. In all groups we found a positive correlation between visual acuity and the differential light sensitivity. At the same visual acuity we did not find any obvious difference in sensitivity between the groups. Correlation and regression line were similar for both groups. The mean relative sensitivity was lower in the fovea than in the rest of the tested field. A selective effect of silicone oil on either spatial resolution or differential light sensitivity could not be verified. The intraoperative application of daunomycin had no influence on the functional results.

Abstract
Summary
Objective: An assessment of the quality of health information on the Internet is an absolute necessity. In this study ‘sensitive’ information was defined as information found in documents published on the Internet, which could be used in a medical decision. For sensitive information, the main criterion chosen for the quality of the information was an indication of the level of evidence. A survey was conducted using the CISMeF health catalogue to assess how often a score of the level of evidence is mentioned in the information accessible on the Internet in French-language health resources.
Methods: Since 1999, members of the CISMeF team have systematically been searching for all documents containing ‘sensitive’ information and verifying whether the level of evidence was explicitly indicated as a score at least once in the document.
Results: As of June 2001, 10,190 resources were included in CISMeF; including 2964 textual ‘sensitive’ resources (29.1%). Out of all these resources, only 4.7% (95% confidence interval: 4.0 - 5.5%) indicated the level of evidence. A statistically significant difference in the prevalence of indicating the level of evidence according to resource types (e.g., 18.1% for guidelines compared to 0.0% for teaching material), year of publication (almost three times greater in 1997-2001 compared with 1990-1996) and publishers was observed.
Conclusion: As the number of people accessing the growing amount of information on the Internet is increasing daily, publishers have an ethical obligation to inform their readers about the validity of ‘sensitive’ information their sites contain. However, the vast majority of the French language Internet resources that were surveyed do not mention a score of the level of evidence for their sensitive information.

Abstract
OBJECTIVES Few data are available to describe the changes in incidence of pediatric-onset inflammatory bowel disease (IBD). The aim of this study was to describe changes in incidence and phenotypic presentation of pediatric-onset IBD in northern France during a 24-year period. METHODS Pediatric-onset IBD (<17 years) was issued from a population-based IBD study in France between 1988 and 2011. Age groups and digestive location were defined according to the Paris classification. RESULTS 1,350 incident cases were recorded (8.3% of all IBD) including 990 Crohn's disease (CD), 326 ulcerative colitis (UC) and 34 IBD unclassified (IBDU). Median age at diagnosis was similar in CD (14.4 years (Q1=11.8-Q3=16.0)) and UC (14.0 years (11.0-16.0)) and did not change over time. There were significantly more males with CD (females/males=0.82) than UC (females/males=1.25) (P=0.0042). Median time between onset of symptoms and IBD diagnosis was consistently 3 months (1-6). Mean incidence was 4.4/105 for IBD overall (3.2 for CD, 1.1 for UC and 0.1 for IBDU). From 1988-1990 to 2009-2011, a dramatic increase in incidences of both CD and UC were observed in adolescents (10-16 years): for CD from 4.2 to 9.5/105 (+126%; P<0.001) and for UC, from 1.6 to 4.1/105 (+156%; P<0.001). No modification in age or location at diagnosis was observed in either CD or UC. CONCLUSIONS In this population-based study, CD and UC incidences increased dramatically in adolescents across a 24-year span, suggesting that one or more strong environmental factors may predispose this population to IBD.

Abstract
We have developed an InAs/InP quantum dot (QD) C-band coherent comb laser (CCL) module with actively stabilized absolute wavelength and power, and channel spacing of 34.462 GHz with ± 100 ppm accuracy. The total output power is up to 46 mW. The integrated average relative intensity noise (RIN) values of the lasing spectrum and a filtered single channel at 1540.19 nm were -165.6 dB/Hz and -130.3 dB/Hz respectively in the frequency range from 10 MHz to 10 GHz. The optical linewidth of the 45 filtered individual channels between 1531.77 nm to 1543.77 nm ranged from 850 kHz to 2.16 MHz. We have also analyzed the noise behaviors of each individual channel.

Abstract
BACKGROUND AND AIMS Data on extra-intestinal manifestations [EIM] and their impact on the disease course of ulcerative colitis [UC] in population-based cohorts are scarce, particularly in paediatric- and elderly-onset UC patients. The aims of this population-based study were to assess: 1] the occurrence of EIM in paediatric- and elderly-onset UC; 2] the factors associated with EIM; and 3] their impact on long-term disease outcome. METHODS Paediatric-onset [< 17 years at diagnosis] and elderly-onset UC patients [> 60 years at diagnosis] from a French prospective population-based registry [EPIMAD] were included. Data on EIM and other clinical factors at diagnosis and at maximal follow-up were collected. RESULTS In all, 158 paediatric- and 470 elderly-onset patients were included [median age at diagnosis 14.5 and 68.8 years, median follow-up 11.2 and 6.2 years, respectively]. EIM occurred in 8.9% of childhood- and 3% of elderly-onset patients at diagnosis and in 16.7% and 2.2% of individuals during follow-up [p < 0.01], respectively. The most frequent EIM was joint involvement [15.8% of paediatric onset and 2.6% of elderly-onset]. Presence of EIM at diagnosis was associated with more severe disease course [need for immunosuppressants or biologic therapy or colectomy] in both paediatric- and elderly-onset UC (hazard ratio [HR] = 2.0, 95% confidence interval [CI]: 1.0-4.2; and HR = 2.8, 0.9-7.9, respectively). Extensive colitis was another independent risk factor in both age groups. CONCLUSIONS Elderly-onset UC patients had lower risk of EIM either at diagnosis or during follow-up than paediatric-onset individuals. EIM at diagnosis predicted more severe disease outcome, including need for immunosuppressive or biologic therapy or surgery, in both paediatric- and elderly-onset UC.
