Abstract
For many years, pig production has focused on maximizing performance by selecting for maximal muscle growth and feeding diets that allow the animals to express their genetic potential. However, it is unclear whether this selection for muscle deposition has affected the capacity of pigs to cope with by-product-based diets, which rely on fat as the primary energy source instead of starches and sugars. Therefore, an experiment was set up to investigate if different types of boars affect how their progeny cope with alternative ingredients in the diet, with a possible need for adapted breeding schemes. Two types of boars within the Piétrain sire line were used based on either a high or low estimated breeding value for daily feed intake (HFI: high feed intake, low feed intake). When their progeny reached 14 weeks of age, two dietary strategies were compared: a control (CON) vs a by-product-based diet high in fat and fiber (HFF). The CON diet was mainly based on cereals (corn, wheat, barley) and soybean meal. The HFF diet was formulated to contain the same net energy, CP and digestible amino acid levels without any cereals or soybean meal. In total 192 animals were included in the experiment (48 animals/type of boar/diet) and performance, digestibility, carcass and meat quality were compared. None of the parameters showed a significant interaction (P < 0.05) between the type of boar and diet, suggesting that shifting to diets that are less prone to feed-food competition is equally feasible in different types of pigs. Type of boar did affect performance, carcass quality and intramuscular fat content. HFI pigs showed higher daily feed intake (DFI) and daily gain (P < 0.001), with no significant difference in feed conversion ratio (P = 0.205), lower carcass quality (P < 0.001) and higher intramuscular fat content (P = 0.030). For both boar types, pigs fed the CON diet performed better, with a higher daily gain (P = 0.028), DFI (P = 0.011) and dressing yield (P = 0.009) and better digestibility (P < 0.001), but without differences in feed conversion ratio or meat quality. In conclusion, there was no indication that pigs differing in feed intake capacity cope differently with a high-fat, high-fiber diet based on by-products. Different types of pigs may cope well with diets that are less prone to feed-food competition.

Abstract
BACKGROUND Transcriptomic studies often require collection of fresh tissues post euthanasia. The chosen euthanasia method might have the potential to induce variations in gene expressions that are unlinked with the experimental design. The present study compared the suitability of 'nitrogen gas in foam' (ANOXIA) in comparison to a non-barbiturate anaesthetic, T-61® (T61), for euthanizing piglets used in transcriptome research. Further, the effect of common tissue storage conditions, RNAlater™ (RL) and snap freezing in liquid nitrogen (LN2), on gene expression profiles were also analysed. RESULTS On comparison of the 3'mRNA-Seq data generated from pituitary, hypothalamus, liver and lung tissues, no significant differential expression in the protein coding genes were detected between the euthanasia methods. This implies that the nitrogen anoxia method could be a suitable alternative for euthanasia of piglets used in transcriptomic research. However, small nuclear RNAs (snRNAs) that constitute the eukaryotic spliceosomal machinery were found to be significantly higher (log2fold change ≥ 2.0, and adjusted p value ≤ 0.1) in pituitary samples collected using ANOXIA. Non-protein coding genes like snRNAs that play an important role in pre-mRNA splicing can subsequently modify gene expression. Storage in RL was found to be superior in preserving RNA compared to LN2 storage, as evidenced by the significantly higher RIN values in representative samples. However, storage in RL as opposed to LN2, also influenced differential gene expression in multiple tissues, perhaps as a result of its inability to inhibit biological activity during storage. Hence such external sources of variations should be carefully considered before arriving at research conclusions. CONCLUSIONS Source of biological variations like euthanasia method and storage condition can confound research findings. Even if we are unable to prevent the effect of these external factors, it will be useful to identify the impact of these variables on the parameter under observation and thereby prevent misinterpretation of our results.

Abstract
Abstract
Background
Evidences on atrial fibrillation (AF) in patients with cancer are limited, specifically with respect to antithrombotic therapy.
Methods
BLITZ-AF Cancer is a prospective, non-interventional study of the epidemiology and management of AF in patients with cancer. Patients were included from 112 cardiology units in Italy, Belgium, Netherlands, Spain, Portugal, and Ireland, based on the following criteria: age ≥18 years; documented cancer other than basal-cell or squamous-cell carcinoma of the skin diagnosed within 3 years; electrocardiographically confirmed AF within 1 year; no concomitant interventional study. Follow-up is ongoing.
Results
From June 26th, 2019 to Sep. 30th, 2021, 1,514 subjects were enrolled.
The most frequent cancer locations were lung (14.9%), colorectal (14.1%), breast (13.9%), prostate (8.8%), and non-Hodgkin lymphoma (8.1%); 463 (30.6%) of participants had metastases.
AF was first-detected in 323 (21.3%), paroxysmal in 460 (30.4%), persistent in 192 (12.7%), long-standing persistent in 33 (2.2%), and permanent in 506 (33.4%); 590 (39.0%) patients had symptoms attributable to AF.
Baseline characteristics are presented in Table 1. Males were more than women and almost half of the subjects was >75 years-old. Cardiovascular risk factors were common and approximately 31% had heart failure or coronary artery disease. Previous thromboembolic and haemorrhagic events had occurred in 14% and 10% of subjects, respectively. The median CHA2DS2VASc score was 3.
As shown in Figure 1, the prescription of oral anticoagulants, especially direct-acting ones (DOACs), rose after the cardiology assessment, while the percentage of participants without any antithrombotic therapy declined.
Among 1,427 patients with non-valvular AF (i.e., no mitral stenosis or prosthetic mechanical valve), 997 (69.9%) were prescribed on DOACs at discharge/after consultation. At multivariable logistic regression analysis, variables associated with DOAC use were female sex (OR 1.58, 95% CI 1.22–2.05), age (OR 2.00, 95% CI 1.39–2.88 and OR 2.63, 95% CI 1.84–3.76, respectively, for 65–74 years and ≥75 years vs <65 years), hypertension (OR 1.43, 95% CI 1.10–1.87), long-standing persistent or permanent AF (OR 1.36, 95% CI 1.05–1.78). Haemoglobin <12 g/dL (OR 0.57, 95% CI 0.45–0.73), and planned cancer treatment (OR 0.72, 95% CI 0.57–0.92) were independently associated with a lower prescription of DOACs.
Conclusions
BLITZ-AF Cancer provides extensive information on a large, contemporary cohort of individuals with AF and cancer. This baseline snapshot indicates that cardiologists pursue the implementation of DOACs in these patients, although residual use of other antithrombotic therapies or lack of any thrombo-prophylaxis remains substantial.

Abstract
Abstract
Background
Treatment for breast cancer (BC) frequently involves radiotherapy. Guidelines recommend screening for cardiac adverse events starting 10 years after radiotherapy. The rationale for recommending this interval is unclear and informed the objective of this study.
Objectives
Study cardiovascular event rates in the first decade following curative radiotherapy for breast cancer, the time frame before guidelines recommend screening.
Methods
We performed a monocentric, retrospective study enrolling all women with unilateral BC in 2007–2008, who received radiotherapy as part of their curative treatment. We compared event rates during 10 years follow-up with an age and risk factor-matched control population (FLEMENGHO population).
Results
We included 1095 BC patients (median age 55y, IQR: 47–66y). Two hundred and eighteen (19.9%) women died. Cancer and cardiovascular mortality accounted for 107 (49.1%) and 22 (10.1%) deaths, respectively. The incidence of coronary artery disease was similar compared to age and risk-matched women [risk ratio 0.75 (95% CI 0.48–1.18)], yet heart failure (HF) [risk ratio 1.97 (95% CI 1.19–3.25)] and atrial fibrillation or flutter (AF) (risk ratio 1.82 (95% CI 1.07–3.08) occurred more often. Age [HR 1.040 (95% CI 1.012–1.069)], tumor grade [HR 1.646 (95% CI 1.103–2.458)], and neo-adjuvant treatment setting [HR 3.079 (95% CI 1.432–6.620)] were risk factors for mortality; hormonal therapy [HR 0.007 (95% CI 0.001–0.042)] proved protective. Risk factors for MACE were mean heart dose [HR 1.079 (95% CI 1.012–1.151], hormonal therapy, history of cardiovascular disease [HR 2.771 (95% CI 1.253–6.126)], and Mayo Clinic Cardiotoxicity Risk Score [HR 2.547 (95% CI 1.538–4.217)]. While mean heart dose [HR 1.141 (95% CI 1.017–1.282)] and cardiovascular history [HR 3.374 (95% CI 1.259–9.043] clearly associated with new onset HF, only a trend towards higher AF burden with increasing mean heart dose could be observed.
Conclusions
Ten-year mortality following curative treatment for unilateral BC was mainly cancer-related. HF and AF constituted significantly increased risks in the first decade following irradiation. Mean heart dose, pre-existing cardiovascular diseases, and Mayo Clinic Cardiotoxicity Risk Score were risk factors for early cardiac mortality and adverse events and should guide early dedicated cardio-oncological follow-up.

Abstract
Abstract
Background
Obesity, especially abdominal fat accumulation, is strongly associated with various metabolic comorbidities. Whether simple anthropometric measures are independently associated with atherogenic lipoproteins is not completely clear.
Methods
We randomly recruited 505 participants (51.5% women; mean age: 48.8 years) from the Flemish community, who had undergone lipoprotein particle measurements by nuclear magnetic resonance spectroscopy and conventional lipid measurements. Each lipoprotein fraction was subgrouped into large, medium, and small subclass. Anthropometric measures included body mass index (BMI) and waist-to-hip ratio (WHR), and defined BMI obesity as BMI ≥30 kg/m2, and WHR obesity as WHR ≥0.85 (women) or 0.9 (men).
Results
In the multivariable logistic regression analysis, total very-low-density lipoprotein (VLDL) particle and its subclasses were positively associated with BMI obesity (adjusted odds ratio [OR] for total VLDL: 2.37; 95% confidence interval [CI]: 1.70–3.31) and WHR obesity (OR for total VLDL: 2.06 [95% CI: 1.55–2.73]). The level of total high-density lipoprotein (HDL) particle and its subclass was negatively associated with BMI (OR for total HDL: 0.63 [95% CI: 0.45–0.90), but not with WHR (P≥0.11). None of the low-density lipoprotein (LDL) particles was associated with the two types of obesity (P≥0.092). BMI was inversely associated with the size of LDL and HDL particles, whereas high WHR was significantly associated with smaller VLDL and HDL sizes. For conventional lipid measures, both BMI and WHR were independently associated with high triglyceride and remnant cholesterol, both mainly driven from VLDL particles, and low HDL cholesterol (P≤0.008). These associations were confirmed in multivariable linear regression analysis, except the association of BMI with HDL number and the association of WHR with HDL size. With partial least squares analysis, the lipoprotein profiles of BMI and WHR were significantly associated with a high 10-year cardiovascular disease risk score, the homeostasis model assessment-estimated insulin resistance (HOMA-IR), and C-reactive protein.
Conclusion
BMI and WHR were independently associated with high triglyceride-rich lipoproteins, decreased HDL cholesterol. The size of LDL and HDL was more consistently associated with BMI than WHR. The lipoprotein alterations may link obesity with high cardiometabolic risk.

Abstract
Abstract
Background
Imbalance of collagen I (COL1) turnover, featured by increased synthesis and decreased degradation of collagen fibers, is a hallmark of fibrosis in the heart and blood vessels that associates with poor cardiovascular outcomes. Such as imbalance of COL1 turnover could be reflected in urine and serve as fingerprint for future adverse outcomes in general population, and high risk subjects.
Purpose
We hypothesize that imbalance of proteomic signatures of urinary peptides (UPs) reflecting COL1 turnover relate to adverse health outcomes in participants from a general population
Methods
We randomly recruited 776 participants (51.2% women; 50.5 years) from the Flemish Study on Environment, Genes and Health Outcomes cohort and measured UPs proteome by capillary electrophoresis coupled with mass spectrometry. Our analyses focused on 148 peptides of COL1 alpha-1 (COL1A1) chain that retained ≥70% signal in the whole sample. The primary endpoint included fatal and nonfatal cardiovascular endpoints. Secondary endpoints consisted of total mortality, fatal and nonfatal cardiac, coronary, and heart failure endpoints. Multivariate Cox proportional models, partial least squares analysis (PLS), log-likelihood test, and receiver operating characteristics (ROC) curve were applied.
Results
Over a median follow up of 12.4 years, 110 primary endpoints occurred, 61 participants died, 81, 41 and 24 experienced cardiac, coronary, and heart failure endpoints; respectively. In PLS analyses, upregulation of UPs signatures closer to C- and N-terminal locations of the COL1A1 chain whereas downregulation of mid-region UPs were associated with lower risk of adverse health outcomes. This pattern was inverted in subjects with cardiovascular disease, as upregulation of terminal and downregulation of mid region UPs increased risk. Adding UPs to a basic model including sex, age and usual cardiovascular risk factors significantly improved model performance between 2.54% to 4.93% (P≤0.001) for prediction of adverse health outcomes. In ROC plots, adding UPs to the basic model increased the area under the curve up to 4.00% (P<0.012).
Conclusions
UPs reflecting COL1 turnover predicted adverse health outcomes. The inverted up- and down regulations of UPs in between participants with and without previous cardiovascular diseases might be explained by a shift in the UPs signatures of COL1 fragments linked to distinct fibrotic processes. Urinary proteomic might have clinical importance in documenting the extent of collagen accumulation that relates to adverse health outcomes. In patients at high cardiovascular risk, modification of collagen I fibers turnover might be a potential treatment target

Abstract
Abstract
Background
In rare cases, immune checkpoint inhibitors (ICIs) cause immune-mediated myocarditis. However, the true incidence of other major adverse cardiovascular events (MACE) following ICI treatment remains unknown, mainly because late occurring side effects are rarely reported in prospective clinical trials.
Purpose
To identify the incidence and risk factors of MACE in a real-life ICI-treated cancer cohort and to compare the incidence with non-ICI-treated cancer patients and population controls.
Methods
In total, 672 ICI-treated patients were included. The primary endpoint was MACE, a composite of acute coronary syndrome, heart failure, stroke and transient ischemic attack. Secondary outcomes were acute coronary syndrome and heart failure separately. Incidence rates were compared between groups after matching according to age, sex, cardiovascular history and cancer type.
Results
Incidence of MACE was 10.3% during a median time of follow-up of 13 months (IQR 6 to 22). In multivariable analysis, a history of heart failure (hazard ratio (HR): 2.27; 95% confidence interval (CI): 1.03 to 5.04; p=0.043) and valvular heart disease (HR 3.01; 95% CI: 1.05 to 8.66; p=0.041) remained significantly associated with MACE.
Cumulative incidence rates were significantly higher in the matched ICI group (rate at full range of follow-up (rate): 8.51; 95% CI: 6.18 to 11.4) compared with the cancer cohort not exposed to ICI (rate: 5.20; 95% CI: 3.56 to 7.35; p=0.032) and the population controls (rate: 2.55; 95% CI: 2.16 to 2.99; p<0.001) mainly driven by a higher risk of heart failure events (Figure 1).
Conclusions
Cardiovascular events during and after ICI treatment are more common than currently appreciated. Patients at risk are those with a history of cardiovascular disease. Compared with matched cancer and population controls, MACE incidence rates are significantly higher, suggesting a potential harmful effect of ICI treatment besides the underlying risk.

Abstract
STUDY QUESTION Can severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA be detected in the reproductive tract of asymptomatic patients undergoing ART? SUMMARY ANSWER SARS-CoV-2 mRNA is not detectable in semen, follicular fluid, vaginal secretions or residual medulla from ovarian tissue cryopreservation procedures in asymptomatic patients who undergo ART, irrespective of the results of a triage questionnaire and a nasopharyngeal SARS-CoV-2 RNA detection test. WHAT IS KNOWN ALREADY The SARS-CoV-2 pandemic had a huge impact on the activities of fertility clinics. Although some studies reported the presence of SARS-CoV-2 mRNA in the reproductive system during or after acute COVID-19 symptomatic infections, uncertainties remain regarding the presence of viral mRNA in the reproductive material and follicular fluid of asymptomatic patients undergoing ART. STUDY DESIGN, SIZE, DURATION An observational cohort trial of residual material samples including semen, follicular fluid, vaginal secretions and ovarian medulla was conducted during the second pandemic wave in Brussels from September 2020 to April 2021. PARTICIPANTS/MATERIALS, SETTING, METHODS All patients who underwent ART (IUI, IVF/ICSI, oocyte and ovarian tissue cryopreservation) responded to a triage questionnaire at the beginning and end of the cycle and underwent nasopharyngeal swab collection for SARS-CoV-2 RNA detection by RT-PCR before the procedure according to standard recommendations. For semen analysis, only the questionnaire was requested the day before the sample collection. The ART cycles of patients with positive nasopharyngeal SARS-CoV-2 RNA detection tests and/or questionnaires were cancelled except for those that could not be postponed. After providing informed consent, swabs on residual materials were collected the day of the oocyte, ovarian tissue or semen collection and were processed for RT-qPCR. MAIN RESULTS AND THE ROLE OF CHANCE A total of 394 samples from 291 patients were analysed. Amongst them, 20 samples were obtained from patients with a positive questionnaire but negative nasopharyngeal SARS-CoV-2 test and 20 others were from patients with a positive nasopharyngeal SARS-CoV-2 test. The remaining samples were collected from patients with a negative or unknown nasopharyngeal SARS-CoV-2 test and/or a negative or unknown triage questionnaire. Viral RNA for SARS-CoV-2 was undetectable in all of the samples. LIMITATIONS, REASONS FOR CAUTION Considering the cancellation policy, only a limited number of samples from patients with positive triage questionnaires or nasopharyngeal SARS-CoV-2 tests were included in the analysis. WIDER IMPLICATIONS OF THE FINDINGS The study suggested that there was no risk of reproductive tract contamination by SARS-CoV-2 in asymptomatic patients, irrespective of the results from a triage questionnaire or nasopharyngeal SARS-CoV-2 test. The results suggested that no additional measures to prevent staff or cross-patient contamination need to be implemented in the IVF and andrology laboratories.

Abstract
Sheep scab, caused by Psoroptes ovis mites, represents a significant threat to sheep health and welfare. Infestations are diagnosed by parasite identification in skin scrapings, and more recently with a commercial ELISA against serum antibodies to the Pso o 2 mite allergen. However, little is known about the performance of the ELISA in non-UK sheep populations. In this study, six Swifter sheep were experimentally infested with P. ovis. Lesion sizes were monitored and serum IgG against Pso o 2 and the novel Pso-EIP-1 antigens were measured by ELISA. Although all sheep showed signs of infestation, serum from two animals failed to react with Pso o 2. However, they did react to Pso-EIP-1. This indicates that cases of sheep scab in (Swifter) sheep may remain undetected using the Pso o 2 ELISA, which may have implications for routine screening of non- UK sheep breeds.

Abstract
Abstract
Background
Cardiac allograft vasculopathy (CAV) is the major long-term complications after heart transplantation, leading to mortality and re-transplantation. As available noninvasive biomarkers are scarce for CAV screening, we aimed to identify a proteomic signature for CAV detection.
Methods
Urinary proteome was measured by capillary electrophoresis coupled to mass spectrometry in 217 heart transplantation recipients. Participants were further randomly and evenly divided into the derivation cohort and validation cohort. The proteomic signature for CAV was identified by decision tree-based machine learning in the derivation cohort and further tested in the validation cohort. The pathway analysis was investigated with Reactome Pathway Database.
Results
We identified a proteomic signature with 27 urinary peptides, which yielded areas under the curve (AUC) of 0.83 and 0.71 in the derivation and validation cohort, respectively. In the validation cohort, it had a sensitivity of 68.4%, specificity of 73.2%, accuracy of 71.6%, negative predictive value of 81.3%. Including the proteomic signature into the basic model further improved the diagnostic accuracy with an relative integrated discrimination improvement of 25.9% and the continuous net reclassification improvement of 83.3% (p≤0.023). The pathways analysis on revealed that collagen turnover, platelet aggregation and coagulation, cell adhesion and motility might involve in the pathogenesis of CAV.
Conclusions
The proteomic signature might be valuable for the surveillance of CAV thereby reduce the frequency of invasive procedures after HTx. Moreover, the highlighted pathways might provide insights in the potential novel treatment targets for CAV.

Abstract
Abstract
Introduction
Nanomedicine offers great potential for treatment of cardiovascular disease. We tested whether direct intramyocardial (IM) injection of pro-angiogenic hepatocyte growth factor (HGF) and pro-myogenic insulin-like growth factor (IGF-1) encapsulated in Alginate-Sulfate nanoparticles (AlgS-NP) enhances myocardial retention, controlled release and improves myocardial repair in a porcine ischemia-reperfusion model.
Methods
Bioactivity of HGF/IGF, released from AlgS-NP, was determined by cell proliferation assays in vitro. Myocardial infarction (MI) was induced by 75min balloon occlusion of the mid-LAD followed by reperfusion. After 1w, pigs (n=12) with marked LV dysfunction (EF<45%) were randomized to fusion imaging-guided IM injections of 8 mg Cy5-labelled AlgS-NP loaded with 200μg HGF and 200μg IGF-1 (GF) or with phosphate-buffered saline (CON) using the MYOSTAR injection catheter. AlgS-NP retention after IM or intracoronary (IC) injection was determined by measuring Cy5 plasma levels. At 8w, treatment effect was evaluated using in vivo magnetic resonance imaging and coronary physiological measurements, and via post-mortem analysis of myocardial fibrosis and cardiomyocyte circumference.
Results
We confirmed the bioactivity of the AlgS-NP-released GF in C2C12 and HUVEC cell proliferation assays after 72h culture, being similar to the free GF (Fig. A). AlgS-NP retention was tested in a pig model, 1w after MI. Ejection fraction (EF) was 37±5% (range 27–45%) and infarct size (IS)/LVmass 24±6% (range 19–38%). AlgS-NP retention was better after IM delivery than after IC infusion with plasma Cy5 levels at 30 min after treatment indicating 5% systemic leakage for IM vs. 20% for IC. After 8w, IS/LVmass decreased 8% in GF-treated pigs vs. 3% in CON (P=0.03, Fig. B) and was associated with preserved myocardial blood flow during hyperemia in the infarct (P=0.036) and peri-infarct (PI) zones (P=0.008), increased coronary flow reserve (P=0.05) and decreased index of microcirculatory resistance (P=0.02). LVEF significantly increased in GF-treated pigs (+6±2% vs. −1±1% in CON, P=0.02, Fig. C), and was accompanied by significantly reduced fibrosis (P=0.01) and increased hypertrophy of cardiomyocyte (P=0.03) in the PI zone.
Conclusions
IM injection of AlgS-NP-encapsulated HGF and IGF-1 to the ischemic myocardium significantly improves LV repair, and offers the prospect of innovative treatment for patients with refractory ischemic heart disease.

Abstract
Abstract
Background
Although arterial stiffness is an independent predictor of cardiovascular outcomes, its physiopathology remains unclear.
Purpose
This study aimed to investigate the urinary proteomic profile of aortic stiffness and provide insights into pathogenetic processes of arterial stiffness by pathway analysis.
Methods
In 669 participants (mean age, 50.5 years; 48.9% men) randomly recruited from the Flemish population, we measured carotid-femoral pulse wave velocity (PWV) by applanation tonometry. The proteomics of urine samples was quantified by using capillary electrophoresis coupled mass spectrometry. The proteomic data were analysed by the orthogonal projections to latent structures, a supervised dimensional reduction statistic method and summarised as a urinary proteomic (UP) score.
Results
The mean values were 7.56±2.02 m/s for PWV and 7.59±1.95 unit for the UP score. PWV was significantly associated with the UP score before and after adjustment for the potential covariates (β coefficient: 0.81 and 0.75, respectively; p<0.001). The significant proteins in the urinary proteomic profile consisted of 43 kinds of proteins, including collagen I, II and III, fibrinogen, matrix Gla-protein, apolipoprotein A-I and A-VI. The pathways annotated by the significant proteins mainly involved in fibrosis, signal conduction, platelet activation and aggregation.
Conclusions
In conclusion, the urinary proteomic profile could be a new biomarker of aortic stiffness and the altered proteins may link to the underlying mechanisms and holds the potential to discover novel therapeutic targets for arterial stiffness.

Abstract
Abstract
Background and purpose
Increased morbidity and mortality caused by side-effects of cancer treatment on cardiovascular function mandates careful monitoring and shared decision-making in cardio-oncology clinics. We report the experience of the cardio-oncology clinic at a large Belgian tertiary care center, without mandatory physician referral, and investigated the predictability of cardiotoxicity based on pre-existing cardiovascular risk factors, specific cancer treatment and existing risk scores of the American Society of Clinical Oncology (ASCO) and Mayo Clinic.
Methods
We included all patients seen at the outpatient cardio-oncology clinic between May 2018 and September 2020. We defined cardiotoxicity as a decline in ejection fraction (EF) of 10% in asymptomatic patients and 5% in symptomatic patients. Approval of the ethical committee was obtained (S65084).
Results
The majority were women (68%), with almost half (44%) having metastatic disease. Mean age was 63.4±16.0 years. The most frequent oncological diagnoses were breast cancer (33%) and haematological diseases (24%). Patients most frequently received radiation therapy (42%), anthracyclines (39%) and antimetabolites (35%). Mean follow-up was 443±245 days.
Receiver operating characteristic (ROC) analysis of predictors of cardiotoxicity showed an area under the curve (AUC) of 0.580 (CI 95% bootstrap: 0.525–0.642) for cardiovascular risk factors alone, and an AUC of 0.613 (CI 95% bootstrap: 0.550–0.676) when treatment was added to the model. The ASCO risk score poorly predicted cardiotoxicity (sensitivity 64%, specificity 52%). The Mayo Clinic cardiotoxicity risk score was the best predictor of cardiotoxicity with an AUC of 0.685 (CI 95% bootstrap: 0.625–0.743).
Discussion
Classic cardiovascular risk factors alone, or in combination with the proposed cancer treatment cannot adequately predict cardiotoxicity risk. The Mayo Clinic Cardiotoxicity Risk score outperformed the ASCO risk score but requires further refinement to enhance adequate cardiovascular risk prediction. For future model building, we hypothesize that an all-comer population of oncological patients should be used as a derivation cohort, regardless of previous or current cardiac issues, risk factors or type of therapy. Admittedly, individual susceptibility due to genetic, epigenetic and environmental predisposition cannot be adequately incorporated into a risk score and emphasizes the need for individual cardiotoxicity risk evaluation using bed to bench tools such as the use of induced pluripotent stem cell derived cardiac or vascular cells to assess the susceptibility of individual patients to cancer drug-induced cardiovascular toxicities. In the absence of adequate risk prediction tools, we advocate standardized screening of all patients before oncological treatment starts.

Abstract
PURPOSE Fluid boluses (FB) are often used in post-cardiac arrest (CA) patients with haemodynamic instability. Although FB may improve cardiac output (CO) and mean arterial pressure (MAP), FB may also increase central venous pressure (CVP), reduce arterial PaO2, dilute haemoglobin and cause interstitial oedema. The aim of the present study was to investigate the net effect of FB administration on cerebral tissue oxygenation saturation (SctO2) in post-CA patients. METHODS Pre-planned sub-study of the Neuroprotect post-CA trial (NCT02541591). Patients with anticipated fluid responsiveness based on stroke volume variation (SVV) or passive leg raising test were administered a FB of 500 ml plasma-lyte A (Baxter Healthcare) and underwent pre- and post-FB assessments of stroke volume, CO, MAP, CVP, haemoglobin, PaO2 and SctO2. RESULTS 52 patients (mean age 64 ± 12 years, 75% male) received a total of 115 FB. Although administration of a FB resulted in a significant increase of stroke volume (63 ± 22 vs 67 ± 23 mL, p = 0.001), CO (4,2 ± 1,6 vs 4,4 ± 1,7 L/min, p = 0.001) and MAP (74,8 ± 13,2 vs 79,2 ± 12,9 mmHg, p = 0.004), it did not improve SctO2 (68.54 ± 6.99 vs 68.70 ± 6.80%, p = 0.49). Fluid bolus administration also resulted in a significant increase of CVP (10,0 ± 4,5 vs 10,7 ± 4,9 mmHg, p = 0.02), but did not affect PaO2 (99 ± 31 vs 94 ± 31 mmHg, p = 0.15) or haemoglobin concentrations (12,9 ± 2,1 vs 12,8 ± 2,2 g/dL, p = 0.10). In a multivariate model, FB-induced changes in CO (beta 0,77; p = 0.004) and in CVP (beta -0,23; p = 0.02) but not in MAP (beta 0,02; p = 0.18) predicted post-FB ΔSctO2. CONCLUSIONS Despite improvements in CO and MAP, FB administration did not improve SctO2 in post-cardiac arrest patients.

Is SARS-CoV–2 detected by RT-PCR in the reproductive materials and follicular fluid of asymptomatic patients undergoing fertility treatments?
Summary answer
No SARS-CoV–2 mRNA was detected in sperm, vaginal and follicular fluids samples of asymptomatic patients, irrespective of the nasopharyngeal swab or COVID–19 questionnaire results. What is known already: The COVID–19 pandemic had a huge impact on health care including on fertility clinics. While activities were interrupted during the first wave, ART cycles are currently performed but uncertainties remain regarding the presence of the virus in reproductive materials. The SARS-CoV–2 receptors were detected in reproductive organs but only few studies with limited number of cases reported the presence of SARS-CoV–2mRNA in semen of symptomatic patients. In women, the risk of SARS-CoV–2 contamination in follicular and vaginal fluids remains uncertain. Thus the risk of sexual transmission and the safety of the IVF laboratory procedures are unclear.
Study design, size, duration
This COVART study is an observational cohort prospective trial conducted at a Belgian academic hospital. Between September 2020 and January 2021, 208 asymptomatic adults patients (men and women) undergoing ART treatments (sperm analysis, IUI, ICSI/ICF cycles, oocyte cryopreservation) were included in the trial after informed consent. All patients followed standard procedures to evaluate COVID–19 risk (nasopharyngeal swab during ovarian stimulation and COVID–19 risk questionnaire). Participants were divided into two groups: COVID–19 positive and negative/unknown groups. Participants/materials, setting, methods: Swabs on the residual reproductive materials were done and stored in viral transport medium at 4 °C until processing. After addition of an internal control in each sample and virus inactivation with Trizol, mRNA was extracted using phenol-chloroform method. Quantitative RT-PCR was performed in duplicate following a previously validated protocol (45 cycles, Roche Light Cycler 480). Negative/positive controls were used to validate each run. The test was considered as positive when CT < 40.
Main results and the role of chance
A total of 399 samples (126 semen, 162 vaginal fluid, 111 follicular fluid samples) of reproductive residual materials from 208 participants were collected during the peak of the second wave of COVID–19 pandemic, when Belgium was considered as a red zone with a viral Rt of 1.516 and a 14-day COVID–19 cases notification rate above 630 per 100000. Although the policy of the fertility clinic was to cancel all cycles of patients with a positive nasopharyngeal swab test except if specific medical raisons to continue the cycle, 14 samples from 9 non-cancelled patients diagnosed with COVID–19 before or just after the samples collection were analyzed (4 sperm, 5 follicular fluid and 5 vaginal secretion samples). For the 199 remaining patients, the COVID–19 status was negative or unknown. None of the samples were considered as positive after quantitative RT-PCR analysis.
Limitations, reasons for caution
All the patients were asymptomatic at the time of the samples collection and the large majority was negatively diagnosed for COVID–19 during the ART cycle. The results should be confirmed by including a larger cohort of positive patients. Data on the impact on ART outcomes will be evaluated.
Wider implications of the findings: We showed that contaminations of sperm, follicular and vaginal fluids with SARS-CoV–2 are unlikely in asymptomatic patients, even when diagnosed positive, confirming the poor risk of sexual transmission. Moreover, no additional safety measures seems to be implemented in the IVF laboratory to ensure the safety of the staff.

Background
Heart transplantation (HTX) is a therapeutic option in a selected group of patients with end-stage heart failure. Although cardiac function normalizes after surgery, maximal exercise capacity of HTX-patients after 1 year is only half that of age- and gender matched healthy subjects. Data on the evolution of muscle strength and physical activity after HTX are scant. Having this knowledge might help to optimize rehabilitation programs.
Purpose
To describe changes in muscle strength and physical activity following HTX.
Methods
58 HTX-patients were addressed, of whom 52 (90%) patients participated in the study. Study visits were planned every 3 months from hospital discharge until 1 year of follow-up. 43 HTX-patients (67% male; age: 48 ± 14 years; BMI: 24 ± 4 kg/m²) fulfilled the study protocol. Outcome measures included functional exercise capacity (6MWD), peripheral strength (QF), respiratory muscle strength (MIP) and objectively measured physical activity (PAwalk, walking intensity (WI), PAsteps). All patients received physiotherapy at home during the first 6 weeks, as standard of care after thoracic surgery. After that, cardiac rehabilitation in a specialized center was started. Data were analyzed using repeated measures ANOVA, with Bonferroni test as post-hoc test.
Results
6MWD (+178 ± 17 meter), QF (+26 ± 4 Nm) and MIP (-32 ± 3 cmH2O) significantly improved over time (p < 0.0001). Despite improvements in QF, peripheral muscle weakness was still present in 32% of patients 1 year post-HTX. A significant time effect in PA (PAwalk (+33 ± 7 minutes/day), WI (+0.036 ± 0.007 g) and PAsteps (+3711 ± 640 steps/day)) could be noticed (p < 0.0001). Sedentary time did not significantly change during follow-up (p = 0.14). (Figure 1)
Conclusion
Functional exercise capacity and muscle strength gradually improve during 1 year after HTX. A considerable number of patients still present with peripheral muscle weakness. Despite improvements in PA, results remain below recommended health levels. Enrollment in a cardiac rehabilitation program, offering a combined exercise and PA intervention seems warranted to further enhance health outcomes in this patient population.

Abstract
Boar taint is an unpleasant taste and odor that can occur in entire male pigs and is caused by androstenone, skatole, and to a lesser extent indole accumulating in fat tissue. In the present observational study, we evaluated an extensive list of such potential risk factors which influence boar taint: social hierarchy and puberty attainment, housing, health, preslaughter conditions, season, feed, carcass composition, slaughter weight or age, and breed. Details on these factors were collected by interviews with the participating farmers, observations on each farm by trained observers and farmers, as well as slaughterhouse data. Twenty-two farms (in West- and East-Flanders, ranging from 160 to 600 sows, selected on suitability) raising entire male pigs were included in the study to evaluate the link between boar taint and potential risk factors related to the farm and slaughter batch (114 slaughter batches and 16 791 entire male pigs in total). Average olfactory boar taint prevalence was 1.8 ± 0.8%. Boar taint prevalence varied also within farms up to a maximum range between slaughter batches of 9.1% which suggests an effect of factors varying between slaughter batches such as season or other variables varying between slaughter batches. Less aggressive behavior at the end of fattening as well as lower skin lesion scores at fattening as well as at slaughter could be associated with less boar taint. The same might be said for sexual behavior, though less convincingly from this study. Measures that reduce aggression and stress have therefore have the potential to lower boar taint prevalence. The same might be said for sexual behavior, though less convincingly from this study. Furthermore, boar taint prevalence was generally higher in winter than in summer, which is relevant from a planning perspective for the slaughterhouses to seek alternative markets. Finally, increased CP gave significantly lower boar taint prevalences. This may to some extent be explained by the negative association between boar taint and lean meat percentage, as increased dietary CP levels promote the carcass lean meat percentages which can then be associated with lower boar taint levels.

Abstract
Abstract
Background
Bleeding and ischemic complications are the main cause of morbidity and mortality in critically ill cardiogenic shock patients, supported by short-term percutaneous mechanical circulatory support (pMCS) devices. Hence, finding the optimal antithrombotic regimen is challenging. Bleeding not only occurs because of heparin and antiplatelet therapy (both required in the prevention of pump and acute stent thrombosis) but also because of device- and disease related coagulopathy. To prevent clotting-related device failure, most centers target full therapeutic heparin anticoagulation levels in left ventricular (LV) Impella™ supported patients in analogy with Veno-Arterial Extracorporeal Membrane Oxygenation. We aimed to investigate the safety (related to bleeding and thrombotic complications) of targeting low-dose versus therapeutic heparin levels in left Impella™-supported cardiogenic shock patients on dual antiplatelet therapy (DAPT).
Methods
In this hypothesis generating pilot study, we investigated 114 patients supported for at least two days by LV Impella™ mechanical support due to cardiogenic shock at three tertiary ICUs, highly specialized in mechanical support. Low-dose heparin (aPTT 40–60s or anti-Xa 0.2–0.3) was compared to standard of care (aPTT 60–80s or anti-Xa 0.3–0.5). Major adverse cardio- and cerebrovascular events (MACCE; composite of death, myocardial infarction, stroke/transient ischemic attack) and BARC bleeding (bleeding academic research consortium classification) during 30 day follow-up were assessed. Inverse probability of treatment weighting (IPTW) analysis was calculated with age, gender, arterial hypertension, diabetes mellitus, smoking, chronic kidney disease, previous stroke, previous myocardial infarction, previous coronary arterial bypass grafting, hypercholesterolemia and DAPT as matching variables. COX regression analysis was conducted to test for robustness.
Results
IPTW revealed 52 patients in the low-dose heparin group and 62 patients in the therapeutic group. Mean age of patients after IPTW was 62±16 years in the intermediate and 62±13 years in the therapeutic group (p=0.99). 25% and 42.2% were male (p=0.92). Overall bleeding events and major (BARC3b) bleeding events were higher in the therapeutic heparin group (overall bleeding: Hazard ratio [HR]=2.58, 95% confidence interval [CI] 1.2–5.5; p=0.015; BARC 3b: HR=4.4, 95% CI 1.4–13.6, p=0.009). Minor bleeding (BARC3a) as well as MACCE and its single components (ischemic events) did not differ between both groups. These findings were robust in the COX regression analysis.
Conclusion
In this pilot analysis, low-dose heparin in 114 LV Impella™ cardiogenic shock patients was associated with less bleeding without increased ischemic events, adjusted for DAPT. Reducing the target heparin levels in critically ill patients supported by LV Impella™ might improve the outcome of this precarious group. These findings need to be validated in randomized clinical trials.

Abstract
Abstract
Background
Acute mitral regurgitation (MR) is an emergency, often requiring urgent surgery. Severe acute MR presenting with hemodynamic collapse is usually caused by papillary muscle rupture or dysfunction after acute myocardial infarction (AMI) or chordal rupture, resulting in flail mitral leaflet(s). Preoperative stabilization is complex due to concomitant hemodynamic collapse and hypoxic respiratory failure. Finding the right balance between both preload and inotropic support is challenging. When patients are too sick for immediate surgical intervention, mechanical circulatory support can be considered because of its ability to both unload and reduce of cardiac work while increasing coronary perfusion and cardiac output. Nevertheless, even after initial stabilization, surgical risk remains high in critically ill acute severe MR patients and transcatheter treatments such as MitraClip are increasingly being explored.
Methods
Between August 2017 and September 2019, patients presenting with acute severe mitral regurgitation and considered too ill for immediate surgical intervention (EURO-II score >11.2% plus pulmonary oedema necessitating mechanical ventilation and/or hemodynamic instability), were selected for an Impella-assisted LV unloading technique as bridge to MitraClip-procedure. Five patients were selected for the combined left Impella/MitraClip-procedure in two tertiary cardiac ICUs.
Results
The mean age was 72 years. The cause of MR was ischemic in 20% and all patients presented in cardiogenic shock state, necessitating mechanical ventilation. The overall cardiac operative risk assessment (Euro-II) score predicted a 35% chance of in-hospital mortality. Cardiac output was severely impaired (mean LVOT VTI 8.2 cm). All patients were on inotropic support and supported by an Impella-CP pVAD (mean flow 2.5 Liter per minute; mean 6.3 days of support). In all cases, we managed to reduce the LVEDP below 15 mmHg using the combination of medical therapy (afterload reduction, inotropes), mechanical ventilation and pVAD-therapy. The MR was significantly reduced by a MitraClip-procedure in each Impella supported patient. The overall survival at discharge was 80%. One patient with late referral and multiple organ failure at presentation deceased due to refractory cardiogenic shock. Overall, severe MR was reduced to grade 1+ and all four patients survived 6 months after discharge with only one readmission for decompensated heart failure.
Conclusions
A combined strategy of Impella and MitraClip appears to be a novel, feasible alternative for patients presenting with acute, severe MR unable to proceed to a corrective surgical procedure at presentation due to severe left ventricular forward flow failure. In these cases, the early initiation of pVAD-support may reduce the risk of development of irreversible end- organ damage and dysfunction. Exploration in a larger, randomised population is warranted to investigate this strategy further.

Abstract
Abstract
Introduction
The acute inflammatory response contributes substantially to functional recovery and remodelling of the left ventricle after acute ischemic injury. Previously, we have shown that the C-Type Lectin Receptor CLEC4E plays a role in early leukocyte recruitment during the acute inflammatory response of ischemia-reperfusion injury (I/R). However, the role of CLEC4E signalling in functional recovery of the left ventricle after I/R remains unknown. Therefore, we studied the chronic inflammatory response and left-ventricular remodelling in murine gene deletion model of Clec4e, subjected to I/R.
Methods
In anesthetized C57Bl6/J wild-type (n=14) and Clec4e−/− (n=13) mice, we transiently occluded the left-descending artery for 60 min, followed by 4 weeks reperfusion (I/R). A blood sample was collected at 90 minutes reperfusion to measure high-sensitivity troponin I (TnI) levels, as a surrogate marker of cardiac damage. At 4 weeks, mice underwent MRI (7T) to investigate the effect of Clec4e-gene deletion on LV-remodelling.
Results
Plasma TnI-levels showed no statistical difference between both groups, indicating that the initial insult was comparable. In wild-type mice, plasma TnI-levels negatively correlated with ejection fraction (EF, R2=0.92 p<0.0001) at 4 weeks I/R, while Clec4e−/− mice showed preserved EF, irrespective of 90 minutes TnI-levels. MRI-analysis at 4 weeks after I/R showed significantly smaller end-diastolic and end-systolic volumes in Clec4e−/− mice, together with a trend towards a higher ejection fraction, suggesting better preserved structural and functional LV-remodelling (Fig.1).
Conclusion
The inflammatory leukocyte-associated Clec4e signalling pathway impairs functional recovery of the left ventricle after myocardial I/R injury. Inhibition of the Clec4e receptor may be a promising strategy in the treatment of ischemic injury.

Abstract
Abstract
Introduction
Nanomedicine offers great potential for treatment of cardiovascular disease. We tested whether intramyocardial (IM) injection of pro-angiogenic hepatocyte growth factor (HGF) and anti-apoptotic, pro-myogenic insulin-like growth factor 1 (IGF-1) encapsulated in Alginate-Sulfate nanoparticles (AlgS-NP) improves left ventricular (LV) functional recovery in a porcine ischemia-reperfusion (I/R) model.
Methods
Myocardial infarction (MI) was induced by 75min balloon occlusion of the mid-LAD followed by reperfusion. After 1w, pigs (n=12) with marked LV dysfunction (EF<45%) were randomized to fusion imaging-guided IM injections of 8 mg Cy5-labelled AlgS-NP loaded with 200μg HGF and IGF-1 (GF) or with phosphate-buffered saline (CON) using the MYOSTAR injection catheter. AlgS-NP retention in the heart was determined by measuring Cy5 levels in peripheral blood. At 8w, treatment effect was evaluated using cardiac magnetic resonance imaging and coronary flow reserve (CFR) measurements, and further assessed using sirius red staining to measure myocardial fibrosis.
Results
At 1w after MI, LV ejection frqction (LVEF) was 37±5% (range 27–45%) and infarct size (IS)/LV mass 24±6% (range 19–38%). Myocardial retention of AlgS-NP was comparable between 2 groups (maximal systemic leakage after IM injection: 9% CON vs 20% GF, P=0.25). After 8 w, IS/LV mass decreased by one third in GF-treated pigs compared with 14% in CON (P=0.03, Fig. A) and was associated with a trend towards improvement in CFR (P=0.05, Fig. B). LVEF significantly increased in GF-treated pigs (6±2% vs. −1±1%, P=0.02, Fig. C), which was attributable to a greater reduction in end-systolic volume. The improvement in LVEF was also consistent with significant reduction of fibrosis (P=0.01, Fig. D) in the peri-infarct zone (PI).
Conclusions
Intramyocardial injection of AlgS-nanoparticle-encapsulated HGF and IGF-1 to the ischemic myocardium significantly improves LV repair, and offers the prospect of innovative treatment for patients with refractory ischemic heart disease.

Abstract
Background
Bleeding is a main cause of morbidity and mortality in critically ill cardiogenic shock patients, supported by short-term percutaneous mechanical circulatory support (pMCS) devices. Bleeding not only occurs because of obligatory heparin and antiplatelet therapy (both required in the prevention of pump and stent thrombosis) but possibly also results from device-related coagulopathy. Similar to long-term ventricular assist devices, mechanical shear-induced acquired von Willebrand syndrome (AVWS) might further increase the bleeding risk. Therefore, we aimed to investigate the effect of left Impella percutaneous continuous flow pumps on the development of AVWS due to shear-induced excessive cleavage of large vWF multimers by the metalloproteinase ADAMTS-13, resulting in loss of high-molecular-weight vWF multimers.
Methods
Between March 2019 and January 2020, all cardiogenic shock patients supported by a left Impella and referred to a single tertiary ICU were studied. Both vWF Antigen (vWF:Ag) and vWF:GPIbR (ristocetin-induced binding of vWF to a recombinant wildtype Glycoprotein Ib fragment) levels were measured by chemiluminescent immunoassays using an AcuStar (Werfen) assay to determine the vWF:GPIbR /vWF:Ag ratio (normal range ≥1.0). VWF multimer analysis was performed by electrophoresis. On-pump analyses were performed 12h after implantation and off-pump analyses 12h after Impella explantation. Patients who died on-pump were excluded because of lack of paired data after explantation.
Results
Eight left Impella patients (four Impella CP, four Impella 5.0) were analyzed for AVWS. The vWF:GPIbR /vWF:Ag ratio was <1.0 in all patients on-pump (mean±SD 0.68±0.1 versus 1.1±0.15 off-pump (panel A; p=0.0018)) and thus AVWS was detected in all Impella-supported patients. The presence of AVSW was also confirmed by loss of large vWF multimers on-pump (panel B). Four patients (50%) had mucosal bleeds (epistaxis or gastrointestinal), none of them requiring transfusion. The mean rise in ratio 12h after pump removal was 0.35 which was also reflected by recovery of large multimers by electrophoresis (panel B).
Conclusions
Our data highlight the rapid onset and reversal of AVWS in all studied cardiogenic shock patients, supported by a left Impella pump. The determination of the GPIbR /vWF:Ag ratio with the AcuStar appears a reliable and faster test to detect AVWS as compared to vWF multimers electrophoresis. Further research into innovative pharmacological interventions (e.g. ADAMTS-13 inhibitors) should target pMCS-induced AVWS in an effort to reduce hemostatic complications in this critically ill ICU population.

Abstract
Abstract
Introduction
End-stage heart failure (HF) can be successfully treated with heart transplantation (HTx), which reduces mortality and improves quality of life (QoL). Diastolic dysfunction and subsequently increased left ventricular (LV) filling pressures can be an early sign of rejection, while later after HTx, they can be suggestive for other insults to the myocardium, for example related to transplant vasculopathy. Therefore, right heart catheterization (RHC) remains a standard follow-up examination in patients after HTx. It has been questioned, whether echocardiography can accurately predict the LV filling pressures in HTx patients, and whether echocardiographic diastolic parameters correlate with hemodynamics in this population. Therefore, our study aimed to investigate the correlation between invasive measurements and echocardiographic estimates of LV filling pressures in HTx patients.
Methods
We analyzed 461 consecutive HTx patients who underwent RHC and transthoracic echocardiography on the same day. Patients were classified as having elevated LV filling pressures when the pulmonary capillary wedge (PCWP) was ≥15 mmHg. Standard echocardiographic parameters of systolic and diastolic function were measured and the decision tree of the recommendations on diastolic dysfunction assessment of the American and European imaging societies (ASE/EACVI) was applied to detect elevated LV filling pressures and determine the diastolic dysfunction grade.
Results
The invasive measurements showed elevated LV filling pressures in 303 (66%) of HTx patients. Based on the echocardiographic parameters, HTx patients were classified into the following groups: normal diastolic function (n=151, 33%), grade I (n=87, 19%), grade II (n=21,5%), and grade III (n=151, 33%) diastolic dysfunction, and indetermined group (n=51, 11%). The PCWP values differed between the groups: 14.4±0.3 mmHg vs. 13.3±0.4 vs. 20.5±0.9 mmHg vs. 22.2±0.3 mmHg vs. 17.7±0.6 mmHg, p=0.0001, accordingly (Figure A). The PCWP showed moderate correlation with E/A (r=0.49, p=0.0001) and E/e' (r=0.40, p=0.0001) (Figures B and C, resp.). The decision tree of the ASE/EACVI recommendations predicted elevated LV filling pressures with a sensitivity of 64%, specificity of 98%, negative predictive value of 59% and positive predictive value (PPV) of 98%.
Conclusions
Our study is the first to demonstrate a correlation between the LV filling pressures estimated from echocardiography and invasively measured during RHC in large HTx population. Echocardiography alone can reliably describe elevated LV filling pressures with a high PPV. The sensitivity of the algorithm, however, is limited. Additional parameters need to be identified to increase the sensitivity of the current recommendations for detection of elevated filling pressures this patients population.

Abstract
Background PLINK is probably the most used program for analyzing SNP genotypes and runs of homozygosity (ROH), both in human and in animal populations. The last decade, ROH analyses have become the state-of-the-art method for inbreeding assessment. In PLINK, the --homozyg function is used to perform ROH analyses and relies on several input settings. These settings can have a large impact on the outcome and default values are not always appropriate for medium density SNP array data. Guidelines for a robust and uniform ROH analysis in PLINK using medium density data are lacking, albeit these guidelines are vital for comparing different ROH studies. In this study, 8 populations of different livestock and pet species are used to demonstrate the importance of PLINK input settings. Moreover, the effects of pruning SNPs for low minor allele frequencies and linkage disequilibrium on ROH detection are shown. Results We introduce the genome coverage parameter to appropriately estimate FROH and to check the validity of ROH analyses. The effect of pruning for linkage disequilibrium and low minor allele frequencies on ROH analyses is highly population dependent and such pruning may result in missed ROH. PLINK’s minimal density requirement is crucial for medium density genotypes and if set too low, genome coverage of the ROH analysis is limited. Finally, we provide recommendations for the maximal gap, scanning window length and threshold settings. Conclusions In this study, we present guidelines for an adequate and robust ROH analysis in PLINK on medium density SNP data. Furthermore, we advise to report parameter settings in publications, and to validate them prior to analysis. Moreover, we encourage authors to report genome coverage to reflect the ROH analysis’ validity. Implementing these guidelines will substantially improve the overall quality and uniformity of ROH analyses.

Abstract
The present study focuses on the Belgian Milk Sheep in Flanders (Belgium) and compares its genetic diversity and relationship with the Flemish Sheep, the Friesian Milk Sheep, the French Lacaune dairy sheep and other Northern European breeds. For this study, 94 Belgian Milk Sheep, 23 Flemish Sheep and 22 Friesian Milk Sheep were genotyped with the OvineSNP50 array. In addition, 29 unregistered animals phenotypically similar to Belgian Milk Sheep were genotyped using the 15K ISGC chip. Both Belgian and Friesian Milk Sheep as well as the East Friesian Sheep were found to be less diverse than the other seven breeds included in this study. Genomic inbreeding coefficients based on runs of homozygosity (ROH) were estimated at 14.5, 12.4 and 10.2% for Belgian Milk Sheep, Flemish Sheep and Friesian Milk Sheep respectively. Out of 29 unregistered Belgian Milk Sheep, 28 mapped in the registered Belgian Milk Sheep population. Ancestry analysis, PCA and FST calculations showed that Belgian Milk Sheep are more related to Friesian Milk Sheep than to Flemish Sheep, which was contrary to the breeders' expectations. Consequently, breeders may prefer to crossbreed Belgian Milk Sheep with Friesian sheep populations (Friesian Milk Sheep or East Friesian Sheep) in order to increase diversity. This research underlines the usefulness of SNP chip genotyping and ROH analyses for monitoring genetic diversity and studying genetic links in small livestock populations, profiting from internationally available genotypes. As assessment of genetic diversity is vital for long-term breed survival, these results will aid flockbooks to preserve genetic diversity.

Abstract
The Piétrain pig originates from the Belgian village Piétrain some time between 1920 and 1950. Owing to its superior conformation, the Piétrain has spread worldwide since the 1960s. As initial population sizes were limited and close inbreeding was commonplace, the breed’s genetic diversity has been questioned. Therefore, this study examines Piétrain breed substructure, diversity and selection signatures using SNP data in comparison with Duroc, Landrace and Large White populations. Principal component analysis indicated three subpopulations, and FST analysis showed that US Piétrains differ most from European Piétrains. Average inbreeding based on runs of homozygosity (ROH) segments larger than 4 Mb ranged between 16.7 and 20.9%. The highest chromosomal inbreeding levels were found on SSC8 (42.7%). ROH islands were found on SSC8, SSC15 and SSC18 in all Piétrain populations, but numerous population‐specific ROH islands were also detected. Moreover, a large ROH island on SSC8 (34–126 Mb) appears nearly fixed in all Piétrain populations, with a unique genotype. Chromosomal ROH patterns were similar between Piétrain populations. This study shows that Piétrain populations are genetically diverging, with at least three genetically distinct populations worldwide. Increasing genetic diversity in local Piétrain populations by introgression from other Piétrain populations seems to be only limited. Moreover, a unique 90 Mb region on SSC8 appeared largely fixed in the Piétrain breed, indicating that fixation was already present before the 1960s. We believe that strong selection and inbreeding during breed formation fixed these genomic regions in Piétrains. Finally, we hypothesize that independent coat color selection may have led to large ROH pattern similarities on SSC8 between unrelated pig breeds.

Abstract
Abstract
Background
Contemporary treatment options for breast cancer have significantly improved survival during the last two decades. To estimate cancer survival, current practice typically relies on cancer size and the presence of metastases, whereas cardiovascular comorbidities such as atrial arrhythmias are typically not taken into account.
Aim
To evaluate the incidence of atrial fibrillation and flutter among curatively treated breast cancer patients and assess its impact on survival in an all-comer population at a tertiary care centre.
Methods
In a large, single centre, retrospective study we enrolled all patients with a diagnosis of breast cancer in 2007 and 2008 who received radiation therapy as part of their curative treatment regimen. We performed Kaplan-Meier and Cox survival analyses to calculate mortality risk over 10-year follow up.
Results
We included 1338 patients, 1326 (99.1%) of whom were women. Mean age (± standard deviation) at diagnosis was 57.6±13.4 years and the distribution of left sided breast cancer versus right sided or bilateral breast cancer was 655 (49.0%) patients versus 645 (48.2%) and 38 (2.9%) patients, respectively. A total of 805 (60.1%) patients had at least one ECG recorded during the 10 year follow up. In this subgroup, atrial fibrillation or flutter was present in 70 (8.7%); 23 patients had pre-existing atrial fibrillation or flutter (32.9%), 26 patients had had radiation therapy for left sided breast cancer (37.1%) versus 21 patients for right sided breast cancer (30%; p=0.375 for left versus right sided radiation therapy). Of the total cohort, 327 (24.4%) patients died during 10 year follow-up. In the subgroup with at least a single ECG recording, mortality equaled 44.3% (31/70) in patients with one or more documented episodes of atrial fibrillation or flutter during follow-up, compared to 21.9% (161/735) in patients who remained in sinus rhythm (p<0.0001). In patients with pre-existing atrial fibrillation or flutter, mortality equaled 47.8% (11/23) versus 42.6% (20/47) in patients with atrial fibrillation or flutter manifesting after treatment initiation (p=0.683).
Survival Atrial Fibrillation/Flutter
Conclusion
Atrial fibrillation and flutter are common in patients with curative breast cancer treatment and have a significant impact on overall survival. Our study highlights the impact of cardiac comorbidities on overall survival following cancer treatment and emphasizes the importance of a dedicated cardiac follow-up in cancer survivors.

Abstract
GOAL The aim of this study is to assess to what extent psychomotor assessment can aid the clinician in differentiating between schizophrenia and other psychotic disorders. METHODS Enrolled subjects were recent in remission patients (n=304), who all met DSM-IV (APA, 2013) criteria for either schizophrenia (Sz; n=117), schizoaffective disorder (SaD; n=36), psychotic disorder not otherwise specified (P-NOS) (n=86), substance/medication-induced psychotic disorder (SIPD; n=33) or major depressive disorder with psychotic features (MDD-p; n=32). The patients were submitted to a psychomotor test battery. RESULTS Patients with schizophrenia generally perform worse on most tests. Using cluster analysis a combination of three tests, namely the sensory integration subscale of the Neurological Evaluation Scale (NES), a Figure Copying Task (FCT) and the finger tapping test (FTT), came out to be useful to clinically differentiate between schizophrenia and substance-induced psychotic disorder (SIPD) or psychosis not otherwise specified (P-NOS). When comparing schizophrenia only to a group of patients with SIPD, the differentiation potential becomes even greater with a 76.1% chance to correctly diagnose patients with schizophrenia and 75% chance for patients with SIPD. CONCLUSION A combination of NES, FCT and FTT shows promising results as a clinical tool in daily practice to differentiate schizophrenia from other psychotic disorders. Future prospective studies to confirm these results are necessary.

Abstract
One of the challenges in the production of entire male pigs is the occurrence of boar taint. We separately tested the effect of 3 management strategies to reduce boar taint on respectively 2, 3, and 6 Flemish pig farms: 1) adapted feeding strategies, 2) presence of gilts in the compartment, and 3) varying lairage duration at the slaughterhouse. A commercialized feed concept resulted in a significant reduction of olfactory boar taint prevalence when fed for 2 weeks (T2W) compared to control (T-CON) (P = 0.030). For T2W and when fed for 3 weeks (T3W), androstenone (AND) (P = 0.002 for T2W, P = 0.029 for T3W) and skatole (SKA) (P < 0.001 for T2W and T3W) were significantly reduced compared to T-CON. Olfactory boar taint prevalence was significantly reduced when feeding 5% dried chicory roots (FI5%) (P = 0.032), but not for 3% dried chicory roots (FI3%) (P = 0.958). SKA concentration was significantly lower when feeding FI5% (P < 0.001) and when feeding FI3% (P = 0.034). Rearing entire male pigs separately from gilts and increasing lairage duration from <1 h to >3 h did not significantly affect boar taint.

Abstract
ZNF335 plays an essential role in neurogenesis and biallelic variants in ZNF335 have been identified as the cause of severe primary autosomal recessive microcephaly in 2 unrelated families. We describe, herein, 2 additional affected individuals with biallelic ZNF335 variants, 1 individual with a homozygous c.1399 T > C, p.(Cys467Arg) variant, and a second individual with compound heterozygous c.2171_2173delTCT, p.(Phe724del) and c.3998A > G, p.(Glu1333Gly) variants with the latter variant predicted to affect splicing. Whereas the first case presented with early death and a severe phenotype characterized by anterior agyria with prominent extra-axial spaces, absent basal ganglia, and hypoplasia of the brainstem and cerebellum, the second case had a milder clinical presentation with hypomyelination and otherwise preserved brain structures on MRI. Our findings expand the clinical spectrum of ZNF335-associated microcephaly.

Abstract
BACKGROUND Cancer is a major cause of morbidity and mortality after heart transplantation. METHODS We studied 541 heart transplant patients from a single center over a period of 25 years, with a mean follow-up of 10.7 years. We determined incidence, type, risk factors, and prognosis for cancer after heart transplantation. RESULTS Cancer was diagnosed in 181 patients, at a mean of 7.7 years after transplantation. Cumulative incidence of cancer at 5, 10, and 20 years was 14%, 29%, and 60%, respectively. The most frequent cancers were spinocellular skin cancer (22%), basocellular skin cancer (19%), lung cancer (16%), lymphoma (11%) and prostate cancer (10%). Age at transplantation > 50 years (hazard ratio, 2.9; P < .001) and male recipient gender (hazard ratio, 1.7; P = .038) were significant risk factors for posttransplant malignancy on multivariate Cox proportional hazards analysis. Median patient survival after diagnosis of cancer was 2.9 years for patients with noncutaneous cancer, versus 13.1 years for patients with only skin cancer (P < .001).

Abstract
Refractive index gratings have been inscribed in polymer thin films by permanently photobleaching the organic chromophore PYR-3 dopant. The grating inscription process was investigated in detail for the purpose of improving the diffraction efficiency (η) of the PYR-3 doped polymer gratings. Three processes were identified that contributed to the η of the first diffracted order: a periodic change in the refractive index due to photobleaching of the PYR-3, formation of the surface relief grating as a consequence of free volume change during bleaching, and the introduction of periodic, strain-induced changes in the refractive index.

Abstract
Voedselallergie is een veel voorkomend probleem, zowel bij huisdieren als bij de mens. Zo wordt in de diergeneeskunde vaak voedselallergie vastgesteld bij de hond. Verschillende allergenen, zoals vlees, eieren en melk, worden aangeduid als boosdoener bij de hond en soms wordt er kruisreactiviteit gezien tussen verschillende allergenen. Bij de mens zijn vooral pinda’s, noten en koemelk bekend als veelvoorkomende antigenen. De symptomen variëren zowel bij de hond als bij de mens van huidklachten tot gastro-intestinale symptomen. De diagnosestelling van voedselallergie bij de hond gebeurt het beste door middel van een testdieet, bestaande uit twee fasen: de eliminatie- en provocatiefase. Andere testen, zoals de intradermale huidtest, serologie, de basofieldegranulatietest en gastroscopische voedselovergevoeligheidstest zijn ook beschikbaar. Echter, deze testen geven vaak weinig betrouwbare resultaten. De behandeling van voedselallergie berust in de eerste plaats op de eliminatie van het allergeen in de voeding. Dit kan eventueel worden aangevuld met medicatie, zoals corticosteroïden en antihistaminica.

Abstract
PURPOSE Post-cardiac arrest (CA) patients have a large cerebral penumbra at risk for secondary ischemic damage in case of suboptimal brain oxygenation during ICU stay. The aims of this study were to investigate the association between hemoglobin, cerebral oxygenation (SctO2) and outcome in post-CA patients. METHODS Prospective observational study in 82 post-CA patients. Hemoglobin, a corresponding SctO2 measured by NIRS and SVO2 in patients with a pulmonary artery catheter (n=62) were determined hourly during hypothermia in the first 24h of ICU stay. RESULTS We found a strong linear relationship between hemoglobin and mean SctO2 (SctO2=0.70×hemoglobin+56 (R(2) 0.84, p=10(-6))). Hemoglobin levels below 10g/dl generally resulted in lower brain oxygenation. There was a significant association between good neurological outcome (43/82 patients in CPC 1-2 at 180 days post-CA) and admission hemoglobin above 13g/dl (OR 2.76, 95% CI 1.09:7.00, p=0.03) or mean hemoglobin above 12.3g/dl (OR 2.88, 95%CI 1.02:8.16, p=0.04). This association was entirely driven by results obtained in patients with a mean SVO2 below 70% (OR 6.25, 95%CI 1.33:29.43, p=0.01) and a mean SctO2 below 62.5% (OR 5.87, 95%CI 1.08:32.00, p=0.03). CONCLUSION Hemoglobin levels below 10g/dl generally resulted in lower cerebral oxygenation. Average hemoglobin levels below 12.3g/dl were associated with worse outcome in patients with suboptimal SVO2 or SctO2. The safety of a universal restrictive transfusion threshold of 7g/dl can be questioned in post-CA patients.

Abstract
The Asp298Asn polymorphism of the melanocortin-4 receptor (MC4R) in pigs is known to affect economically important traits such as growth rate and backfat thickness. We have assessed the possible use of this polymorphism as a molecular marker to perform genetic selection toward lower boar taint levels without compromising growth performance and carcass and meat quality in commercial boars and gilts. Homozygous boars and gilts of the AA genotype and GG genotype were compared in an intervention study with a 2 × 2 design to assess main effects and possible interactions between sex and genotype. The concentrations of the 3 boar taint compounds androstenone ( = 0.044), skatole ( = 0.049), and indole ( = 0.006) were significantly higher in fat of AA boars compared to GG boars. However, no effect on the sensory analysis of the fat samples could be observed. Between 20 and 115 kg BW, AA pigs showed higher ADFI than GG pigs ( < 0.001). An interaction between genotype and sex was observed for ADG ( = 0.044): AA boars had a significantly higher ADG than GG boars but there was no significant difference between the gilts. Daily lean meat gain tended to be higher in boars compared to gilts ( = 0.051), independent of genotype. Similarly, boars showed higher G:F compared to gilts ( < 0.001), without effect of genotype. Genotype and sex affected several carcass quality parameters but there was no interaction. Pigs of the AA genotype displayed a lower dressing percentage ( = 0.005), lower ham width ( = 0.024), lower muscle thickness ( = 0.011), and higher fat thickness ( < 0.001), resulting in a lower lean meat percentage ( < 0.001) in comparison with GG pigs. Gilts had a significantly higher dressing percentage ( < 0.001), higher muscle thickness ( < 0.001), higher ham width ( < 0.001), and lower ham angle ( < 0.001) compared to boars. Other than the boar taint compounds, meat quality was not affected by genotype. Pork of gilts was darker ( = 0.014) and less exudative during cooking ( < 0.001) and contained more intramuscular fat ( = 0.013). These results indicate that genetic selection against boar taint is possible using this marker. This will also result in lower feed intake and ADG and, consequently, better carcass quality.
