Abstract
OBJECTIVE Loneliness is a concern for patients with schizophrenia. However, the correlates of loneliness in patients with schizophrenia are unclear; thus, the aim of the study is to investigate neuro- and social cognitive mechanisms associated with loneliness in individuals with schizophrenia. METHOD Data from clinical, neurocognitive, and social cognitive assessments were pooled from two cross-national samples (Poland/USA) to examine potential predictors of loneliness in 147 patients with schizophrenia and 103 healthy controls overall. Furthermore, the relationship between social cognition and loneliness was explored in clusters of patients with schizophrenia differing in social cognitive capacity. RESULTS Patients reported higher levels of loneliness than healthy controls. Loneliness was linked to increased negative and affective symptoms in patients. A negative association between loneliness and mentalizing and emotion recognition abilities was found in the patients with social-cognitive impairments, but not in those who performed at normative levels. CONCLUSIONS We have elucidated a novel mechanism which may explain previous inconsistent findings regarding the correlates of loneliness in individuals with schizophrenia.

Abstract
We have carried out an experimental investigation of the spin-wave dynamics in the Au/CoFeB/Au multilayer consisting of a ferromagnetic film with thicknesses of 0.8, 0.9 and 1.0 nm. We employed the Brillouin light scattering spectroscopy to measure the frequency of the spin waves in dependence on the wave vector. Additionally, we characterized the samples by ferromagnetic resonance measurements. We found that the considered samples exhibit perpendicular magnetic anisotropy with low damping, indicating small pumping effects. Furthermore, we found a nonreciprocal dispersion relation pointing at a non-negligible Dzyaloshinskii-Moriya interaction. These results make the Au/CoFeB/Au multilayer a compelling subject for further analysis and as a potential material for future applications within magnonics.

Abstract
Reprogramming the structure of the magnonic bands during their operation is important for controlling spin waves in magnonic devices. Here, we report the tunability of the spin-wave spectra for a triangular shaped deterministic magnonic fractal, which is known as Sierpinski triangle by solving the Landau-Lifshitz-Gilbert equation using a micromagnetic simulations. The spin-wave dynamics change significantly with the variation of iteration number. A wide frequency gap is observed for a structure with an iteration number exceeding some value and a plenty of mini-frequency bandgaps at structures with high iteration number. The frequency gap could be controlled by varying the strength of the magnetic field. A sixfold symmetry in the frequency gap is observed with the variation of the azimuthal angle of the external magnetic field. The spatial distributions of the spin-wave modes allow to identify the bands surrounding the gap. The observations are important for the application of magnetic fractals as a reconfigurable aperiodic magnonic crystals.

Abstract
While considerable emphasis has been put on investigating the mechanisms that drive reduced social connection in patients with schizophrenia (SCZ), recent studies have increasingly focused on the issue of loneliness in SCZ. As both social cognitive bias and self-reported empathy predict loneliness in non-clinical populations, the current study aims to examine the relationship between loneliness, reduced social connection and social cognitive biases, and self-reported empathy in SCZ. Ninety-three adult SCZ and sixty-six matched healthy individuals completed a battery of questionnaires measuring loneliness and social connection (Revised-UCLA Loneliness Scale, Lubben-Social Network Scale, Social Disconnectedness Scale), cognitive biases (Ambiguous Intentions Hostility Questionnaire, Davos Assessment of Cognitive Biases Scale, Cognitive Biases Questionnaire for psychosis) and self-reported empathy (Interpersonal Reactivity Index). Significant predictors of loneliness in SCZ were entered into two latent variables ("Social Threat Bias", "Social Connection"), and structural equation modeling was used to explore the direct and indirect relationships between Social Threat Bias, symptoms. and loneliness in SCZ. Patients reported higher levels of loneliness, cognitive biases and personal distress compared to controls. Furthermore, SCZ reported less social connection and perspective taking compared to controls. Structural equation modeling revealed that Social Threat Bias was linked to increased loneliness in SCZ both directly and indirectly via decreased social connection. Negative symptoms were directly linked with loneliness, while the association between affective symptoms and loneliness was mediated via Social Threat Bias. The results of the current study suggest that social threat bias should be considered while planning the interventions aimed to reduce loneliness in schizophrenia.

Abstract
BACKGROUND The American Joint Committee on Cancer (AJCC) staging system has limited accuracy in predicting survival of gastric cancer patients with inadequate counts of evaluated lymph nodes (LNs). We therefore aimed to develop a prognostic nomogram suitable for clinical applications in such cases. METHODS A total of 1511 noncardia gastric cancer patients treated between 1990 and 2010 in the academic surgical center were reviewed to compare the 7th and 8th editions of the AJCC staging system. A nomogram was developed for the prediction of 5-year survival in patients with less than 16 LNs evaluated (n = 546). External validation was performed using datasets derived from the Polish Gastric Cancer Study Group (n = 668) and the SEER database (n = 11,225). RESULTS The 8th edition of AJCC staging showed better overall discriminatory power compared to the previous version, but no improvement was found for patients with < 16 evaluated LNs. The developed nomogram had better concordance index (0.695) than the former (0.682) or latest (0.680) staging editions, including patients subject to neoadjuvant treatment, and calibration curves showed excellent agreement between the nomogram-predicted and actual survival. High discriminatory power was also demonstrated for both validation cohorts. Subsequently, the nomogram showed the best accuracy for the prediction of 5-year survival through the time-dependent ROC curve analysis in the training and validation cohorts. CONCLUSIONS A clinically relevant nomogram was built for the prediction of 5-year survival in patients with inadequate numbers of LNs evaluated in surgical specimens. The predictive accuracy of the nomogram was validated in two Western populations.

Abstract
Social cognitive deficits are currently considered as one of the main predictors of clinical symptoms and functional outcome in patients with schizophrenia. Multiple studies have suggested that a two-factor solution (low-level vs. high-level) best describes the structure of social cognitive processes in patients. While higher-order processes have been repeatedly linked to negative symptoms, no such association was found for lower-level processes. Thus, the aim of the current study is to examine whether the association between basic social perception processes and symptoms in patients with schizophrenia is mediated by mentalizing abilities. One hundred thirty-nine patients have completed basic social perception (Communicative Interactions Database task CID-12) and mentalizing (Reading the Mind in the Eyes task) tasks. In line with our hypothesis, we have observed full mediation of the effects of basic social perception abilities on negative symptoms via mentalizing abilities in patients. This effect suggests that, similarly as in the case of positive symptoms, a hierarchical nature of social cognitive processes should be considered while investigating negative symptoms of schizophrenia.

Abstract
Peripheral chemoreceptors (PChRs) play a significant role in maintaining adequate oxygenation in the bloodstream. PChRs functionality comprises two components: tonic activity (PChT) which regulates ventilation during normoxia and acute reflex response (peripheral chemosensitivity, PChS), which increases ventilation following a specific stimulus. There is a clear link between augmented PChS and exercise intolerance in patients with heart failure with reduced ejection fraction. It has been also shown that inhibition of PChRs leads to the improvement in exercise capacity. However, it has not been established yet: 1) whether similar mechanisms take part in heart failure with preserved ejection fraction (HFpEF) and 2) which component of PChRs functionality (PChT vs. PChS) is responsible for the benefit seen after the acute experimental blockade. To answer those questions we enrolled 12 stable patients with HFpEF. All participants underwent an assessment of PChT (attenuation of minute ventilation in response to low-dose dopamine infusion), PChS (enhancement of minute ventilation in response to hypoxia) and a symptom-limited cardiopulmonary exercise test on cycle ergometer. All tests were placebo-controlled, double-blinded and performed in a randomized order. Under resting conditions and at normoxia dopamine attenuated minute ventilation and systemic vascular resistance (p = 0.03 for both). These changes were not seen with placebo. Dopamine also decreased ventilatory and mean arterial pressure responses to hypoxia (p < 0.05 for both). Inhibition of PChRs led to a decrease in V˙E/V˙CO2 comparing to placebo (36 ± 3.6 vs. 34.3 ± 3.7, p = 0.04), with no effect on peak oxygen consumption. We found a significant relationship between PChT and the relative decrement of V˙E/V˙CO2 on dopamine comparing to placebo (R = 0.76, p = 0.005). There was a trend for correlation between PChS (on placebo) and V˙E/V˙CO2 during placebo infusion (R = 0.56, p = 0.059), but the relative improvement in V˙E/V˙CO2 was not related to the change in PChS (dopamine vs. placebo). We did not find a significant relationship between PChT and PChS. In conclusion, inhibition of PChRs in HFpEF population improves ventilatory efficiency during exercise. Increased PChS is associated with worse (higher) V˙E/V˙CO2, whereas PChT predicts an improvement in V˙E/V˙CO2 after PChRs inhibition. This results may be meaningful for patient selection in further clinical trials involving PChRs modulation.

Abstract
Background In response to the COVID-19 pandemic, endoscopic societies initially recommended reduction of endoscopic procedures. In particular non-urgent endoscopies should be postponed. However, this might lead to unnecessary delay in diagnosing gastrointestinal conditions. Methods Retrospectively we analysed the gastrointestinal endoscopies performed at the Central Endoscopy Unit of Saarland University Medical Center during seven weeks from 23 March to 10 May 2020 and present our real-world single-centre experience with an individualized rtPCR-based pre-endoscopy SARS-CoV-2 testing strategy. We also present our experience with this strategy in 2021. Results Altogether 359 gastrointestinal endoscopies were performed in the initial period. The testing strategy enabled us to conservatively handle endoscopy programme reduction (44% reduction as compared 2019) during the first wave of the COVID-19 pandemic. The results of COVID-19 rtPCR from nasopharyngeal swabs were available in 89% of patients prior to endoscopies. Apart from six patients with known COVID-19, all other tested patients were negative. The frequencies of endoscopic therapies and clinically significant findings did not differ between patients with or without SARS-CoV-2 tests. In 2021 we were able to unrestrictedly perform all requested endoscopic procedures (> 5000 procedures) by applying the rtPCR-based pre-endoscopy SARS-CoV-2 testing strategy, regardless of next waves of COVID-19. Only two out-patients (1893 out-patient procedures) were tested positive in the year 2021. Conclusion A structured pre-endoscopy SARS-CoV-2 testing strategy is feasible in the clinical routine of an endoscopy unit. rtPCR-based pre-endoscopy SARS-CoV-2 testing safely allowed unrestricted continuation of endoscopic procedures even in the presence of high incidence rates of COVID-19. Given the low frequency of positive tests, the absolute effect of pre-endoscopy testing on viral transmission may be low when FFP-2 masks are regularly used.

Abstract
Gaucher disease (GD) caused by mutation in the GBA gene has a wide spectrum of phenotypes. Besides the storage disorder, secondary alteration of various pathways occurs with modification of the expression of many genes. In our work we analysed the expression profile of genes in adult patients with type 1 GD. METHODS This study was an observational, cross-sectional analysis of a group of twenty patients with type 1 GD and ten healthy volunteers as a control group. First, on the group of ten persons, microarray gene analysis was performed. Afterwards, significantly regulated genes were selected, and the microarray results were confirmed by real-time PCR on the whole study group. RESULTS Based on the microarray results in the pathway analysis, we focused on genes related to chemokines, inflammatory processes, endocytosis, autophagy, and apoptosis. Patients with GD demonstrated up-regulation of genes related to NFkB pathway (NFkB, NKkBR SQSTM1), inflammation (IL-1b), endocytosis and autophagy (BCN1, SMAD), genes coding proteins involved in apoptosis (CASP, NFkB, BCL2) as well as genes related to proteasome degradation (PSMD2, PSMB9) and SNARE complex (SNAP, STX). Simultaneously, we showed down-regulation of genes coding proteins of chemokines and their receptors (GNB4, CCL5). The qRT-PCR results confirmed changes in expression of selected genes. Parallel microarray results showed inhibition of genes related to neurones development and survival (NTRK1) and stimulation of gene expression related to neurodegeneration and apoptosis (BCN1, IL1B). CONCLUSIONS The work revealed different pathway activation, especially inflammatory processes followed by autophagy and apoptosis. Our results also pay attention to new pathways leading to disorders of the functioning of the nervous tissue in patients with type 1 GD, which may lead to the development of polyneuropathy and chronic pain. These are clinical symptoms that severely decrease the quality of life in GD patients.

Abstract
Patients with end-stage renal disease have higher cardiovascular morbidity and mortality compared with the general population. Preemptive kidney transplant (KTx) has been shown to be associated with improved survival, better quality of life, lower healthcare burden, and reduced cardiovascular risk. In this case–control study, we investigated the cardiovascular benefits of two approaches to KTx: with and without previous chronic hemodialysis. We enrolled 21 patients who underwent preemptive KTx and 21 matched controls who received chronic hemodialysis before KTx. Cardiac morphological and functional parameters were assessed by echocardiography. Overall, patients undergoing preemptive KTx showed less extensive cardiac damage compared with controls, as evidenced by higher global longitudinal strain, peak atrial and contractile strain, and early diastolic mitral annular velocity as well as a lower left ventricular mass, left atrial volume index, and the ratio of mitral inflow early diastolic velocity to the mitral annular early diastolic velocity. In the multivariable analysis, the presence of chronic hemodialysis prior to KTx was an independent determinant of post-transplant cardiac functional and structural remodeling. These findings may have important clinical implications, supporting the use of preemptive KTx as a preferred treatment strategy in patients with end-stage renal disease.

Abstract
Magnonics is a budding research field in nanomagnetism and nanoscience that addresses the use of spin waves (magnons) to transmit, store, and process information. The rapid advancements of this field during last one decade in terms of upsurge in research papers, review articles, citations, proposals of devices as well as introduction of new sub-topics prompted us to present the first roadmap on magnonics. This is a collection of 22 sections written by leading experts in this field who review and discuss the current status besides presenting their vision of future perspectives. Today, the principal challenges in applied magnonics are the excitation of sub-100 nm wavelength magnons, their manipulation on the nanoscale and the creation of sub-micrometre devices using low-Gilbert damping magnetic materials and its interconnections to standard electronics. To this end, magnonics offers lower energy consumption, easier integrability and compatibility with CMOS structure, reprogrammability, shorter wavelength, smaller device features, anisotropic properties, negative group velocity, non-reciprocity and efficient tunability by various external stimuli to name a few. Hence, despite being a young research field, magnonics has come a long way since its early inception. This roadmap asserts a milestone for future emerging research directions in magnonics, and hopefully, it will inspire a series of exciting new articles on the same topic in the coming years.

Abstract
Perioperative use of probiotics serves as efficient prophylaxis against postoperative infections after liver transplantation, yet data on long-term effects of pre-transplant probiotic intake is lacking.
The aim of this study was to assess the effects of pre-transplant probiotic administration on long-term results of liver transplantation. This was secondary analysis of a randomized trial. Patients were randomized to receive either 4-strain probiotic or placebo before liver transplantation. Five year graft survival was set as the primary end-point. Secondary end-points comprised serum bilirubin and C-reactive protein (CRP) concentration, international normalized ratio (INR), serum transaminases and gamma-glutamyl transferase (GGT) activity. Study group comprised 44 patients, of whom 21 received probiotics and 23 received placebo with 5-year graft survival of 81.0% and 87.0%, respectively (p = 0.591). Patients in the probiotic arm exhibited lower INR (p = 0.001) and CRP (p = 0.030) over the first 6 post-transplant months. In the absence of hepatitis B or C virus infection, pre-transplant administration of probiotics also reduced aspartate transaminase activity (p = 0.032). In the intervention arm, patients receiving probiotics for under and over 30 days had 5-year graft survival rates of 100% and 66.7%, respectively (p = 0.061). Duration of probiotic intake > 30 days was additionally associated with increased INR (p = 0.031), GGT (p = 0.032) and a tendency towards increased bilirubin (p = 0.074) over first 6 post-transplant months. Pre-transplant administration of probiotics has mild positive influence on 6-month allograft function, yet should not exceed 30 days due to potential negative effects on long-term outcomes.

Abstract
OBJECTIVES To characterize genomes of Klebsiella pneumoniae ST11 NDM-1 responsible for a countrywide outbreak in Poland and compare them phylogenetically with other Polish and international ST11 strains. METHODS Seventy-one carbapenemase-producing K. pneumoniae ST11 isolates from Poland, including 66 representatives of the NDM-1 epidemic from 2012-18, were sequenced using Illumina MiSeq. Additionally, three outbreak isolates were also sequenced using MinION. The clonality and phylogenetic analysis was done by core-genome MLST and SNP approaches. Resistomes, virulomes, K/O antigens and plasmid replicons were screened for. The detailed plasmid analysis was based on full assemblies using Oxford Nanopore Technologies data. RESULTS Chromosomes of the outbreak isolates formed an essentially homogeneous cluster (though accumulating SNPs gradually with time), differing remarkably from other Polish NDM-1/-5-, KPC-2- or OXA-48-producing K. pneumoniae ST11 strains. The cluster belonged to a clade with 72 additional isolates identified worldwide, including closely related NDM-1 producers from several countries, including organisms from Bulgaria and Greece. All these had KL24 and O2v1 antigens and the chromosomal yersiniabactin locus YbST230 residing in the ICEKp11 element. The specific blaNDM-1-carrying Tn125 transposon derivative, named Tn125A, was located in IncFII/pKPX-1- and/or IncR-like plasmids; however, the IncRs rearranged extensively during the outbreak, contributing to highly dynamic plasmid profiles and resistomes. CONCLUSIONS The K. pneumoniae ST11 NDM-1 genotype that has been expanding in Poland since 2012 is largely monoclonal and represents a novel international high-risk lineage that is also spreading in other countries.

Abstract
Liver fibrosis is the common consequence of chronic liver diseases (CLD). Recently liver stiffness measurements (LSM) ≥ 9.1 kPa, as determined by transient elastography (TE), were demonstrated to predict significant fibrosis (stages ≥ F2) in a population-based setting. The PNPLA3 (adiponutrin) p.I148M polymorphism enhances the risk of liver injury. The aim of our study was to investigate the association between the procholestatic ABCB4 polymorphism c.711A>T and LSM ≥ 9.1 kPa in humans as well as the interaction between ABCB4 and PNPLA3 in a mouse model of chronic cholestasis. Prospectively, we recruited 712 patients with CLD (278 women, age 50 ± 13 years) with available TE results; liver biopsy results were available in 165 individuals. The ABCB4 c.711 genotype was determined by PCR-based assays. PNPLA3 expression and liver injury were studied in Abcb4-/- mice and wild-type controls. Overall, median LSM in our cohort was 6.7 kPa, and 226 individuals had LSM ≥ 9.1 kPa. Carriers of the ABCB4 variant c.711A presented more frequently with LSM ≥ 9.1 kPa (OR = 1.33, P = 0.020) and FIB-4 score ≥ 2.67 (OR = 1.38, P = 0.040). The presence of the risk allele was associated (P = 0.002) with FIB-4. In a multivariate model, the ABCB4 variant (OR = 1.43, P = 0.047) as well as BMI (P = 0.043, OR = 1.04) and age (OR = 1.02, P < 0.010) were independent risk factors for fibrosis stage ≥ F2. Abcb4 deficiency in mice led to enhanced liver injury, coupled with a decrease (P = 0.020) of hepatic PNPLA3 expression. To conclude, the procholestatic variant ABCB4 c.711A>T might represent a new genetic risk factor for clinically significant liver fibrosis. Lower expression of PNPLA3 in fibrotic Abcb4-/- livers points to the interaction between phospholipid metabolism and PNPLA3 in progressive liver injury.

Abstract
A significant number of patients with Gaucher disease (GD) suffer from chronic or acute pain that reduces their quality of life. A mutation in lysosomal enzyme β-glucosidase (GCase) leads to an accumulation of glucocerebroside in the macrophage-lineage cells, causing the development of clinical symptoms. Novel studies have revealed that ambroxol (trans-4-(2-amino-3,5-dibromobenzylamino)-cyclohexanol), the well-known mucolytic drug, acts as a chaperone for the mutant, misfolded enzyme. In addition, as has recently been shown, ambroxol is a Nav 1.8 channel blocker in Aβ, Aδ and unmyelinated C fibres, and therefore reduces the transmission of sensory stimuli from the primary afferent neurons to the dorsal spinal cord. In this way, it can act analgetically. Thus, in addition to broncholytic properties, ambroxol combines two other important functions: it enhances enzyme replacement therapy (ERT) and pain management in patients with GD. We present a 38-year-old female patient with type 3 GD who had reported permanent bone pain in the lumbar-sacral part of the spine for over a year without any pathology evidenced in the undertaken, recommended diagnostic tests. The pain was partly controlled with standard analgesics, that is, paracetamol and tramadol. Ambroxol was introduced at a dose of 150mg/d without a noticeable effect. However, when the dose was increased up to 450mg/d, the intensity of pain diminished and subsided within the following months. Two of three attempts to reduce the dose of ambroxol resulted in a pain relapse within a week, which subsided after resetting the previous, higher dose. This observation of the effects of ambroxol in a GD patient is worth considering for other GD patients with chronic pain.

Abstract
OBJECTIVES This study is an attempt to provide an analysis of the influence of implementation of cognitive behavioral intervention (CBI) in patients after cardiovascular implantable electronic device (CIED) implantation on the quality of life following the procedure as well as the level of illness acceptance. METHODS The study group consisted of patients who underwent standard medical care related to CIED implantation and who additionally received CBI. Patients who received only standard medical care related to CIED implantation constituted a control group. CBI consisted of four sessions conducted over 30 (±3) days after the implantation. Demographic, clinicaland psychological factors were assessed.The Acceptance of Illness Scale (AIS) and EuroQol-5D (EQ-5D) were applied. RESULTS In total, 128 patients (women: 36.7%, mean age 64.5 ± 8.9) were included in the study. The proposed cycle of four structured CBI meetings was well accepted by the patients, which is confirmed by their high turnout for these meetings. After six months, quality of life indices were significantly improved in cardiac electrotherapy recipients assigned to CBI, including: Visual Analogue Scale EQ-5D (80.2 ± 11.8 vs. 64.9 ± 14.3; p < 0.0001) and better acceptance of illness (AIS: 35.6 ± 4.3 vs. 28.7 ± 6.1; p < 0.0001). CONCLUSIONS Implementation of CBI in patients after CIED implantation significantly improved indices of quality of life as well as illness acceptance, when compared to the control group of patients in standard care following electrotherapy. CBI showed multiple benefits in this population, as well as ensures the fulfilment of its expected therapeutic effect, while short duration of the intervention did not prolong the hospitalization itself.

Abstract
BACKGROUND Patients with central sleep apnea (CSA) have recently been shown to have improved sleep metrics and quality of life (QoL) with phrenic nerve stimulation (PNS). AIMS The aim of this study was to report the results of a partnership between cardiology, sleep medicine, and electrophysiology in a single clinical center as well as the enrollment, implantation, and follow‑up experience demonstrating both the safety and efficacy of PNS. METHODS This analysis included data from the pilot and pivotal trials investigating the effect of PNS using an implantable transvenous system in patients with CSA. We present our experience and data on the enrollment processes, implantation feasibility and safety, sleep indices, and QoL at 6 and 12 months of follow‑up. RESULTS Between June 2010 and May 2015, cardiology patients were prescreened and 588 of them were sent for in‑home sleep test. Ninety‑six patients were referred for polysomnographic studies, and 33 were enrolled and had an implant attempt, with 31 successfully receiving an implant. The apnea-hypopnea index was reduced in the pilot trial (mean [SD] of 48.7 [15.5] events/h to 22.5 [13.2] events/h; P <0.001) and in the pivotal trial (mean [SD] of 48.3 [18.8] events/h to 26.0 [21.9] events/h; P <0.001). Improvement in QoL was also observed. CONCLUSIONS We showed that PNS improved sleep metrics and QoL in patients with CSA, which is a result of multiple factors, including a comprehensive coordination between cardiology, sleep medicine, and electrophysiology. This ensures appropriate patient identification leading to safe implantation and full patient compliance during follow‑up visits.

Abstract
In this paper, we show that the phase shift of spin waves propagating in the plane of the film can be controlled by a metasurface formed by an ultra-narrow non-magnetic spacer separating edges of the two thin ferromagnetic films. For this purpose, we exploit the strength of the exchange coupling of the RKKY type between the films which allows tuning the phase of the transmitted spin waves in the wide range of angles [-π/2; π/2]. We combined the phase-shift dependency along the interface with the lens equation to demonstrate numerically the metalens for spin waves.

Abstract
The aim of this study was to measure serum neopterin and C-reactive protein (CRP) concen- trations in female dogs with mammary tumours and evaluate the association between the values of these indicators and some clinical characteristics of the tumour. Fifty three female dogs were used for this study, including 43 dogs with mammary gland tumours (10 benign and 33 malignant) and 10 healthy controls. The concentrations of neopterin and CRP were determined using the ELISA technique and commercial ELISA kits. The mean serum neopterin concentration in fe- male dogs with mammary tumours was lower than in healthy dogs, but significant difference was not found. Similarly, there were no significant differences in neopterin concentrations in female dogs based on tumour size, tumour ulceration and metastasis. The mean CRP concentration was significantly higher (p⟨0.05) in dogs with malignant tumours compared to dogs with benign tu- mours and control. Furthermore, serum CRP concentration was significantly higher (p⟨0.05) in dogs with metastatic malignant tumours compared to dogs with non-metastatic mammary tu- mours. The CRP concentration was significantly lower (p⟨0.05) in dogs with tumours less than 3 cm compared to those with larger tumours, and significantly higher in dogs with ulcerated tu- mours compared to those without ulceration. Our findings suggest that the neoplastic process in the mammary gland does not cause significant changes in serum neopterin concentrations in dogs. Higher concentrations of serum CRP in dogs with advanced stages of malignant tumours may suggest that CRP could be a potential prognostic marker in canine malignant mammary tu- mours, but this hypothesis needs further study.

Abstract
We present an immunocompetent patient with transverse myelitis (TM) during acute cytomegalovirus (CMV) infection, as evidenced by a reactive serum CMV IgM and CMV viremia. The patient had an excellent outcome after receiving only high-dose methylprednisolone. Given concerns that practitioners may have around the use of immunosuppressive therapy for this potentially infectious myelopathy, we systematically reviewed the literature to assess outcomes after administration of high-dose corticosteroids to this population. Despite severe disease at clinical nadir with inability to ambulate, immunocompetent patients with acute CMV-associated TM who received high-dose corticosteroids had good clinical outcomes 1 month to 1 year after presentation.

Abstract
BACKGROUND Cardiovascular events (CVE) contribute to serious complications and death after liver transplantation (LT). Troponin I (TnI) level >0.07 mg/L and prior cardiac disease are known to be the independent predictors for posttransplant CVE. We evaluated single-center cardiac workup to predict early cardiovascular morbidity and mortality after LT. PATIENTS AND METHODS We recruited 105 consecutive liver transplant recipients (male/female, 59/46; mean age, 51.66 ± 11.67 years). The cardiological assessment at evaluation for LT included medical history, electrocardiogram, echocardiography, Holter monitoring, and exercise test. We collected data regarding CVE including hypotonia with catecholamine usage, arrhythmia, sudden cardiac death, pulmonary edema, and myocardial infarction within 7 days after LT. RESULTS CVE during LT occurred in 42 recipients (40%) and after LT in 9 patients (8.57%). Proposed cutoff level of TnI >0.07 mg/L did not correlate with CVE during operation (P = .73) or after LT (P = .47). CVE during LT was associated with arterial hypertension in medical history (P <.001), right ventricular systolic pressure (P< .05), and clinical scores: Child-Pugh (P = .04), Model for End-Stage Liver Disease (MELD) (P = .04), MELD incorporating serum sodium (P<.03), and integrated MELD score (P = .01). CVE after LT correlated only with arrhythmia (P<.001) and catecholamine usage (P < .05) perioperatively. Of interest, catecholamine usage during LT was associated with prolonged stay at the intensive care unit (P < .05). CONCLUSION The single-center algorithm with noninvasive cardiac procedures without TnI assessment is optimal in evaluation before LT; however, medical history and severity of the liver disease are crucial for short-term cardiovascular morbidity after LT.

Abstract
On the basis of 20 years' experience, the authors present the immediate and long-term results of operative treatment of Zenker's diverticulum. Comparison of two methods of surgery - diverticulopexia (in 21 patients) and excision (in 16), both associated with upper esophageal sphincter myotomy - shows good immediate and longterm results (from 1 to 19 years), with disappearance of symptoms (dysphagia) in all patients. There was no perioperative mortality. Postoperative complications were most commonly of pulmonary origin and were observed in a third of patients in both groups. In two patients from the group treated with excision, a leak from the suture line occurred, which healed spontaneously. These two patients had transient dysphagia in the postoperative period. On the basis of this analysis, the authors conclude that diverticulopexia is a safer surgical procedure than excision, giving less complications and a very good long-term functional result.

Abstract
BACKGROUND A growing body of evidence supports the belief that yoga benefits physical and mental health. The aim of the study is to investigate whether the sense of coherence and sense of agency are more developed in people practicing hatha-yoga than in the group of people who have never practiced yoga. METHODS TAHE, SOC-29 questionnaire and short microphenomenological interview conducted on a group of 15 people (8 yoga instructors, 7 in the control group). RESULTS It has been shown that the study group has significantly higher scores in both the sense of agency and sense of coherence than the control group. In addition, a statistically significant correlation was observed between the part of the values mentioned above. CONCLUSIONS There are indications that the hatha-yoga exercise increases the sense of agency, which in the long run can contribute to better mental health. In order to find a clear and certain link between the sense of coherence and the sense of agency additional research is necessary.

Abstract
The application of spin waves in communication with information encoded in amplitude and phase could replace or enhance existing microelectronic and microwave devices with significantly decreased energy consumption. Spin waves (SW) are usually transported in a magnetic material shaped to act as a waveguide. However, the implementation of SW transport and switching in plane homogeneous magnetic films and running as a narrow beam with a small divergence angle still present a challenge. We propose a realization of a strong SW switchers based on a patterned yttrium iron garnet (YIG) film that could serve as a magnonic fundamental building block. Our concept relies on the creation of a narrow beam of relatively short-wavelength SW by effect of a total non-reflection, found to be tied to refraction on the decreasing internal magnetic field, near a line of antidots at YIG. Nonreciprocal SW excitation by a microstrip antenna is used for controlling the direction of the signal flow. We demonstrate unique features of the propagation of microwave-excited SW beams, provide insight into their physics and discuss their potential applications in high-frequency devices.

Abstract
BACKGROUND Orthotopic liver retransplantation (reLT) is considered to have poorer outcomes than primary transplantation. The objective of this study was to analyze the impact of medical urgency status as a predictor of patient survival after reLT. METHODS Forty-nine patients who underwent reLT were included in this retrospective study. Urgent or elective status was based on the judgment of the surgical team, selected variables, and the Model for End-Stage Liver Disease score. Multivariate analysis was performed to identify variables associated with patient survival following reLT. RESULTS Overall survival of the patient cohort was 57% at 1 year and 54.3% at 3 years after reTL. Survival in urgent-status patients was 68.8% and 63.4% at 1 and 3 years, respectively, whereas the survival rate for elective patients was 40.0% at both time points. Mortality was significantly associated with elective status (hazard ratio [HR], 2.42; P = .046) at 1 year, but was no longer significant (HR, 2.19; P < .069) after 3 years of follow-up. CONCLUSIONS Elective status is associated with poorer outcome. Patient selection determines long-term survival more than any other single factor, so for patients designated to an elective status, prompt retransplantation should be encouraged.

Abstract
The Compact Linear Collider (CLIC) is an option for a future [Formula: see text] collider operating at centre-of-mass energies up to [Formula: see text], providing sensitivity to a wide range of new physics phenomena and precision physics measurements at the energy frontier. This paper is the first comprehensive presentation of the Higgs physics reach of CLIC operating at three energy stages: [Formula: see text], 1.4 and [Formula: see text]. The initial stage of operation allows the study of Higgs boson production in Higgsstrahlung ([Formula: see text]) and [Formula: see text]-fusion ([Formula: see text]), resulting in precise measurements of the production cross sections, the Higgs total decay width [Formula: see text], and model-independent determinations of the Higgs couplings. Operation at [Formula: see text] provides high-statistics samples of Higgs bosons produced through [Formula: see text]-fusion, enabling tight constraints on the Higgs boson couplings. Studies of the rarer processes [Formula: see text] and [Formula: see text] allow measurements of the top Yukawa coupling and the Higgs boson self-coupling. This paper presents detailed studies of the precision achievable with Higgs measurements at CLIC and describes the interpretation of these measurements in a global fit.

Abstract
Abstract
The aim of this study was to determine the effect of egg water loss during storage and incubation on hatch rates in heavy-type broad-breasted white BUT Big 6 turkeys. Turkey hens started laying eggs at 30 weeks of age. In weeks 2, 8, 16 and 21 of the laying season, 1512 eggs were selected randomly and divided into 4 groups of 378 eggs each. The groups of eggs were stored for 7, 10, 13 or 17 days before incubation. At the beginning and end of the storage period and on days 9, 15, 21 and 24 of incubation, eggs were weighed to determine the percent water loss relative to the egg’s weight. Four incubation cycles of 378 eggs each were performed for each storage period. A total of 16 incubation cycles were carried out (4 weeks of the laying season × 4 egg storage periods) and the following parameters were determined (%): egg fertilization, dead embryos, unhatched eggs and hatchability results from fertilized eggs. The percentages of dead embryos and unhatched poults with physical defects and abnormal position were determined in hatchery waste from each incubation cycle. Egg water loss varied throughout storage and reached 0.57% of total egg weight after 7 days, 0.79% after 10 days, 0.87% after 13 days and 1.28% after 17 days (P≤0.05). After 7 days of storage, egg water loss during a 15-day and 21-day incubation period reached 5.76% and 8.72%, and lower values were noted after 17 days of storage (P≤0.05). Egg water loss of 1.28% during storage resulted in a high rate of early embryonic mortality (14.81%) and a low hatch rate (72.12%) (P≤0.05). High water loss in stored eggs contributed to a higher percentage of congested embryos. During storage, egg water loss reached 0.72% in week 2 of the laying season, 0.78% in week 8 and ≥1% in weeks 16 and 21 of the laying season (P≤0.05). Egg water loss during a 21-day incubation period was similar in weeks 2, 8 and 16 of the laying season, and lower in week 21 (P≤0.05). The hatchability of turkey eggs was lowest in weeks 16 and 21 of the laying season (P≤0.05). Low water loss during incubation contributed to a high rate of late embryonic mortality (13.2%). High water loss during egg storage is accompanied by lower water loss during incubation. Water loss should be monitored after storage and on days 15 and 21 of incubation to evaluate water metabolism in hatching eggs.

Abstract
BACKGROUND Despite great progress and improvement in results of orthotopic liver transplantation (OLTx), 10%-20% of patients still require retransplantation (re-OLTx). The aim of the study was to present long-term results of liver retransplantation and to determine the factors influencing outcomes. PATIENTS AND METHODS From December 1994 to July 2014, a total of 1461 liver transplantations were performed in the Department of General, Transplant and Liver Surgery of Medical University of Warsaw. There were 92 retransplantations (6.3%), including 40 early re-OLTx (up to 30 days). The most common indication for re-OLTx were vascular complications (41/92, 44.6%). Influence of clinical variables on short- and long-term outcomes was analyzed. RESULTS Postoperative mortality was 30.4% (28/92). One-year, 3-year and 5-year survival for all patients was 59.8%, 56.5% and 54.1%, respectively. The best results were achieved in patients undergoing retransplantation due to chronic rejection and biliary complications, whose 5-year survival rates were 75.0% and 72.9% respectively. There was no difference in long-term survival after early and late retransplantations (60.9% and 49.3%, respectively; P = .158). Multivariable analysis revealed factors associated with longer survival of patients, namely, higher preoperative hemoglobin concentration (P = .001), increased blood transfusions (P = .048), and decreased fresh frozen plasma transfusions (P = .004). CONCLUSIONS Liver retransplantation is a method providing satisfactory outcomes in selected patients. The perioperative period has a major impact on patient outcome.

Abstract
BACKGROUND Changes within the gut microbiota contribute to the progression of chronic liver diseases. According to the results of several studies performed in animal models, gut dysbiosis plays an important role in hepatocarcinogenesis. The aim of this study was to explore the characteristics of gut microbiota associated with the presence of hepatocellular cancer (HCC) in patients with cirrhosis of the liver undergoing liver transplantation. METHODS A total of 15 patients with HCC and 15 non-HCC patients matched according to etiology of cirrhosis and Model for End-Stage Liver Disease (MELD) scores who underwent liver transplantations between 2012 and 2014 were included. Analysis of their gut microbial profile was based on prospectively collected stool samples from the pretransplant period. RESULTS Patients with and without HCC were similar with respect to age (P = .506), sex (P = .700), hepatitis C virus (P > .999) and hepatitis B virus (P = .715) infection status, alcoholic liver disease (P > .999), and MELD score (P = .337). Notably, the presence of HCC was associated with significantly increased fecal counts of Escherichia coli (P = .025). Prediction of HCC presence based on E coli counts was associated with the area under the receiver-operating curve of 0.742 (95% confidence interval, 0.564-0.920), with the optimal cutoff on the level of 17.728 (natural logarithm of colony-forming units per 1 g of feces). Sensitivity and specificity rates for the established cutoff were 66.7% and 73.3%, respectively. CONCLUSIONS The profile of gut microbiota associated with the presence of HCC in cirrhotic patients is characterized by increased fecal counts of E coli. Therefore, intestinal overgrowth of E coli may contribute to the process of hepatocarcinogenesis.

Abstract
BACKGROUND Echinococcosis is a zoonosis caused by infestation with any of 4 (of the 16) members of the Echinococcus genus, namely Echinococcus granulosus, Echinococcus multilocularis, Echinococcus oligarthus, and Echinococcus vogelii. The aim of this retrospective analysis was to present the outcomes of patients undergoing liver resection and liver transplantation (LT) for E. multilocularis infection. METHODS A total of 44 patients who underwent surgical treatment of E. multilocularis infection in the period between 1989 and 2014 were included in the study cohort and retrospectively analyzed. RESULTS LT was performed in 22 patients (50.0%), including 4 of 26 patients undergoing initial non-transplant management. Non-transplant procedures comprised liver resection in 23 patients (88.5%), diagnostic laparoscopy in 2 (7.7%), and left adrenalectomy in 1 patient (3.8%). Post-transplantation survival rates were 90%, 85%, and 75% at 1, 5, and 10 years, respectively. CONCLUSION In conclusion, LT for E. multilocularis infection is a safe and effective treatment method.

Abstract
BACKGROUND Liver transplantation (LT) outcomes for patients with poorly differentiated (G3) hepatocellular carcinoma (HCC) are unsatisfactory. The aim of this study was to evaluate outcomes in patients with poorly differentiated HCC undergoing LT. PATIENTS AND METHODS There were 192 HCC patients after LT in the Department of General, Transplant and Liver Surgery, Medical University of Warsaw, between January 2001 and April 2014. The study group comprised 24 patients with poorly differentiated tumors. RESULTS Disease-free survival (DFS) for all patients was 49.5% at 5 years. The 5-year DFS for patients who met the Milan criteria (n = 9, 88.9%) was significantly better compared to those who did not (n = 15, 28.0%, P = .025). Multivariable analysis revealed that only the largest tumor diameter (P = .014) and α-fetoprotein (AFP) concentration (P = .001) were independent risk factors for DFS. The optimal cut-off AFP and tumor size that could distinguish patients with the highest risk were ≥500 ng/mL and ≥3.5 cm, respectively. DFS for patients with AFP <500 ng/mL and tumor size <3.5 cm was 100% after 2.8 years, and for those with ≥500 ng/mL or tumor size ≥3.5 cm was 46.9% after 5 years. However, the DFS for patients with AFP ≥500 ng/mL and tumor size ≥3.5 cm was only 12.5% after 4.7 years (P = .002). CONCLUSIONS Outcomes of patients with poorly differentiated HCC treated with LT can be characterized with acceptable survival when applying criteria based on tumor size <3.5 cm and AFP <500 ng/mL.

Abstract
INTRODUCTION Sexual activity constitutes a significant aspect of health considerably influencing self-assessment of the quality of life. In Poland, data regarding the return in patients with ischaemic heart disease (IHD) to sexual activity are scarce and inadequate. AIM The aim of this work is to analyse the return to sexual activity in patients with IHD after a hospitalisation related to invasive diagnostics of coronary arteries as well as to identify predisposing factors associated with cessation of sexual activity. MATERIAL AND METHODS 98 patients with angiographically documented IHD were involved in retrospective analysis. 46 patients (46.9%) were diagnosed with myocardial infarction (MI), 29 (29.6%) with stable angina (SA) and 23 (23.5%) with unstable angina (UA). Demographic, clinical and psychological factors were assessed. Beck Depression Inventory, State-Trait Anxiety Inventory, Acceptance of Illness Scale, and EuroQol-5D health questionnaires were used. RESULTS The cessation of sexual activity after a hospitalisation due to invasive diagnostics of coronary arteries was noted almost in 1/3 of the IHD patients within 6-months observation period. There were no statistically significant differences in the percentages of sexually active and inactive patients related to gender. The elderly patients were more likely to cease sexual activity (p = 0.006). Sexually active patients also represented significantly lower level of anxiety-trait (p = 0.0003) and anxiety-state (p = 0.001). They also had a higher level of the acceptance of the disease (p = 0.002) at the end of hospitalisation and presented significantly lower severity of depression (p = 0.02). CONCLUSIONS Cessation of sexual activity in patients with IHD after a hospitalisation due to coronarography is associated with their older age, being single, obesity, lower quality of life, depression, higher level of anxiety, and lower acceptance of illness. Underestimating or omitting the realm of sexual health of hospitalised patients with IHD affects the patients' return to sexual activity. Patients with IHD, who decided to discuss, during their hospitalisation, the impact of cardiac disease and the invasive procedure they had undergone on their sexual activity, more frequently return to sexual activity over the 6-months observation period.

Abstract
An inherent element of research and applications in photonics is a beam of light. In magnonics, which is the magnetic counterpart of photonics, where spin waves are used instead of electromagnetic waves to transmit and process information, the lack of a beam source limits exploration. Here, we present an approach enabling generation of narrow spin wave beams in thin homogeneous nanosized ferromagnetic films by microwave current. We show that the desired beam-type behavior can be achieved with the aid of a properly designed coplanar waveguide transducer generating a nonuniform microwave magnetic field. We test this idea using micromagnetic simulations, confirming numerically that the resulting spin wave beams propagate over distances of several micrometers. The proposed approach requires neither inhomogeneity of the ferromagnetic film nor nonuniformity of the biasing magnetic field. It can be generalized to different magnetization configurations and yield multiple spin wave beams of different width at the same frequency.
