Abstract
BACKGROUND Listeriosis is a foodborne infection caused by Listeria monocytogenes. Three main forms of listeriosis are well characterised, but little is known about L monocytogenes-associated spontaneous bacterial peritonitis. We used data from the French national surveillance of listeriosis to perform a nationwide retrospective study. METHODS All patients with L monocytogenes isolated by culture from a peritoneal fluid sample in France between April 1, 1993, and Dec 31, 2022, were included. Individuals for whom bacterial peritonitis was not confirmed and those who also had another type of invasive listeriosis were excluded. A standardised checklist was used to collect demographic, clinical, and biological data as well as antibiotic treatment and follow-up data. The primary outcome was to determine the characteristics of L monocytogenes-associated spontaneous bacterial peritonitis. We did descriptive analyses and assessed risk factors for 1-month mortality using an exploratory multivariable Cox model analysis. FINDINGS Among the 8768 L monocytogenes cases reported, 208 (2%) were patients with L monocytogenes-associated spontaneous bacterial peritonitis. Mean age was 65 years (SD 13), 50 (24%) of 208 patients were female, and 158 (76%) were male (no data on race or ethnicity were available). 200 (98%) of 205 patients with L monocytogenes-associated spontaneous bacterial peritonitis with available data had immunosuppressive comorbidities, including cirrhosis (148 [74%] of 201 with available data), ongoing alcoholism (58 [62%] of 94), and ongoing neoplasia (60 [31%] of 195). Causes of ascites included cirrhosis (146 [70%] of 208), ongoing neoplasia (26 [13%]), end-stage heart failure (13 [6%]), and peritoneal dialysis (11 [5%]). Among those with available data, presentation was pauci-symptomatic and non-specific; only 67 (50%) of 135 patients presented with fever, 49 (37%) of 132 with abdominal pain, and 27 (21%) of 129 with diarrhoea. 61 (29%) of 208 patients were dead at 1 month, 92 (44%) were dead at 3 months, and 109 (52%) were dead at 6 months after diagnosis. Ongoing neoplasia (hazard ratio 2·42 [95% CI 1·05-5·56]; p=0·039), septic shock (8·03 [2·66-24·02]; p=0·0021), and high blood leukocyte count (1·05 [1·00-1·09]; p=0·045) were independently associated with 1-month mortality. INTERPRETATION Despite the non-specific and mild presentation of L monocytogenes-associated spontaneous bacterial peritonitis, the outcome is poor and similar to that of neurolisteriosis, and so identification of L monocytogenes in ascitic fluid samples requires urgent parenteral amoxicillin-based treatment to avoid a fatal outcome.

Abstract
Background Large-scale studies are needed to clarify antimicrobial resistance in the foodborne pathogen Listeria monocytogenes (Lm) and the effectiveness of listeriosis treatment options. Here we examined the antimicrobial resistance patterns in Lm over time and assessed genotype-phenotype concordances. Methods We analyzed 5339 Lm isolates (2908 clinical and 2431 food isolates) collected in France and overseas territories, between 2012 and 2019. Whole genome sequencing was performed for all isolates and antimicrobial resistance profiles inferred from draft assemblies. Antimicrobial susceptibility towards 22 antimicrobials was determined for all clinical isolates, and in food isolates with acquired resistance genes. Findings All tested isolates were resistant to at least 3 different classes of antimicrobials, consistent with Lm intrinsic traits. Acquired antimicrobial resistance in Lm was rare (2.23% isolates) and more prevalent in food (mainly lineage II) compared to clinical isolates (mainly lineage I) (3.74% vs 0.98%, p < 0.0001), and in isolates with disinfectants or stress resistance traits (e.g. bcrABC, 20.20% vs 7.20%, p < 0.0001), suggesting co-selection of resistance in food-production environments. Acquired antimicrobial resistance could be predicted from genomes with high accuracy (>99%), except for ciprofloxacin. Acquired antimicrobial phenotypes were towards tetracyclines (mostly due to tetM), trimethoprim (dfrD), lincosamides (lnuG), macrolides (ermB, mphB) and phenicols (fexA). Interpretation The reference treatment for listeriosis (aminopenicillins/aminoglycosides) remains effective, with no acquired resistance observed. Continuous surveillance of antimicrobial resistance in clinical and food isolates is crucial to detect the emergence of novel resistance.

Abstract
Genomic data on the foodborne pathogen Listeria monocytogenes from Central America are scarce. We analyzed 92 isolates collected during 2009-2019 from different regions in Costa Rica, compared those to publicly available genomes, and identified unrecognized outbreaks. Our findings suggest mandatory reporting of listeriosis in Costa Rica would improve pathogen surveillance.

Abstract
We report a case of fulminant fatal neonatal listeriosis due to horizontal transmission of Listeria monocytogenes (Lm) in a neonatal double room. Genomic analyses reveal a close genetic relationship between clinical isolates, supporting cross-contamination. Oral inoculation experiments in adult and neonatal mice show that neonates are susceptible to a low Lm inoculum and that this susceptibility results from the immaturity of the neonatal gut microbiota. Infected neonates should therefore be isolated for as long as they shed Lm in their feces to avoid horizontal transmission and its dire consequences.

Abstract
Listeria monocytogenes is a life-threatening foodborne pathogen. Here, we report the genomic characterization of a nationwide dataset of 411 clinical and 82 food isolates collected in Taiwan between 2014 and 2019. The observed incidence of listeriosis increased from 0.83 to 7 cases per million population upon implementation of mandatory notification in 2018. Pregnancy-associated cases accounted for 2.8% of human listeriosis and all-cause 7-day mortality was of 11.9% in nonmaternal-neonatal listeriosis. L. monocytogenes was isolated from 90% of raw pork and 34% of chicken products collected in supermarkets. Sublineages SL87, SL5, and SL378 accounted for the majority (65%) of clinical cases. SL87 and SL378 were also predominant (57%) in food products. Five cgMLST clusters accounted for 57% clinical cases, suggesting unnoticed outbreaks spanning up to 6 years. Mandatory notification allowed identifying the magnitude of listeriosis in Taiwan. Continuous real-time genomic surveillance will allow reducing contaminating sources and disease burden. IMPORTANCE Understanding the phylogenetic relationship between clinical and food isolates is important to identify the transmission routes of foodborne diseases. Here, we performed a nationwide study between 2014 and 2019 of both clinical and food Listeria monocytogenes isolates and sequenced their genomes. We show a 9-fold increase in listeriosis reporting upon implementation of mandatory notification. We found that sublineages SL87 and SL378 predominated among both clinical (50%) and food (57%) isolates, and identified five cgMLST clusters accounting for 57% of clinical cases, suggestive of potential protracted sources of contamination over up to 6 years in Taiwan. These findings highlight that mandatory declaration is critical in identifying the burden of listeriosis, and the importance of genome sequencing for a detailed characterization of the pathogenic L. monocytogenes genotypes circulating in Asia.

Abstract
Two species of Listeria are pathogenic, Listeria monocytogenes and Listeria ivanovii. Although studies have shown that dairy ruminants shed Listeria spp. in feces, there is little information about ruminants that do not shed Listeria spp. in their feces but asymptomatically carry them in organs. We evidence that ruminants can asymptomatically carry L. ivanovii in udders and L. monocytogenes and L. ivanovii in tonsils without fecal shedding. Whole-genome sequence of L. monocytogenes and L. ivanovii contained known core genes involved in virulence and antibiotic resistance. This work highlights tonsils and udders as a Listeria intra-host site of colonization.

Abstract
During microbial assessment of cow milk cheese products in the city of Ilorin, Nigeria, a
Listeria
-like isolate was detected that could not be assigned to any known species. Whole-genome sequence analyses against all currently known 26
Listeria
species confirmed that this isolate constitutes a new taxon within the genus
Listeria
, with highest similarity to
Listeria costaricensis
(average nucleotide identity blast of 82.66%, in silico DNA–DNA hybridization of 28.3%). Phenotypically, it differs from
L. costaricensis
by the inability to ferment sucrose, l-fucose and starch. The absence of haemolysis and
Listeria
pathogenic islands suggest that this novel species is not pathogenic for humans and animals. The name Listeria ilorinensis sp. nov. is proposed, with the type strain CLIP 2019/01311T (=CIP 111875T=DSM 111566T).

Introduction
Current rates of new Permanent Pacemaker (PPM) Implantations in the context of Transcatheter Aortic Valve Replacement (TAVR) range from 2-36% and that necessity is related to worse prognosis. The use of self-expanding valves and a lower valve implantation depth are two factors associated with an increased risk of conduction disturbances post-TAVR. Theoretically, cusp overlap implantation technique has the potential to enable a higher valve deployment by eliminating parallax of the delivery catheter.
Aim
To compare the in-hospital incidence of PPM post-TARV using self-expandable valve according to the fluoroscopic guidance technique.
Methods
Retrospective, single-centre study, with evaluation of patients consecutively submitted to TAVR with self-expanding CoreValveTM between July 2020 and December 2021 dichotomized according to the use of cusp overlap implantation technique for fluoroscopic valve implantation guidance.
Results
138 patients were included, predominantly women (57.2%), with a mean age of 78.4±8.0 years old, with severe aortic stenosis of the native valve being the most common indication for TAVI (85.5%). Cusp overlap view technique was applied in 50.7% of the patients (n=70). Frailty and co-morbidities were the most common cause for surgical refusal (54.3%). There was a significantly higher percentage of hypertensive patients (92.9% vs. 77.9%), lower previous aortic valve surgery (2.9% vs. 16.2%) and lower percentage of patients previously medicated with b-blockers in the group of patients in whom was used the cusp overlap technique; there were no other relevant differences related to the baseline characteristics. First degree atrioventricular block was present in 19.6% and complete right bundle block in 13.6% of the patients. Incidence of in-hospital post-TAVR PPM implantation wasn’t significantly different between the two cohorts of patients (cusp overlap vs. standard approach: 24.3% vs. 26.5%, p=0.77) (71.4% implanted in the context of complete heart block). Likewise, there were similar proportions of in-hospital new-onset of complete left bundle branch block (35.8% vs. 37.3%, p=0.86), volume of contrast used (140.6±37.5 mL vs. 145.2±51.5 mL, p=0.12), fluoroscopy time (15.6±8.8 min vs. 19.6±8.9 min, p=0.40) and radiation dose (556.3±320.6 mGy vs. 859.4±531.2 mGy, p=0.06).
Conclusions
This study shows that using the cusp overlap view for self-expanding valve implantation does not seem to achieve a significant reduction in in-hospital PPM implantation rate in comparison with the traditional 3 cusp co-planar fluoroscopic view. A larger and probably randomized clinical trial is needed to confirm these results.

Abstract
Background Whole genome sequencing analyzed by core genome multi-locus sequence typing (cgMLST) is widely used in surveillance of the pathogenic bacteria Listeria monocytogenes. Given the heterogeneity of available bioinformatics tools to define cgMLST alleles, our aim was to identify parameters influencing the precision of cgMLST profiles. Methods We used three L. monocytogenes reference genomes from different phylogenetic lineages and assessed the impact of in vitro (i.e. tested genomes, successive platings, replicates of DNA extraction and sequencing) and in silico parameters (i.e. targeted depth of coverage, depth of coverage, breadth of coverage, assembly metrics, cgMLST workflows, cgMLST completeness) on cgMLST precision made of 1748 core loci. Six cgMLST workflows were tested, comprising assembly-based (BIGSdb, INNUENDO, GENPAT, SeqSphere and BioNumerics) and assembly-free (i.e. kmer-based MentaLiST) allele callers. Principal component analyses and generalized linear models were used to identify the most impactful parameters on cgMLST precision. Results The isolate’s genetic background, cgMLST workflows, cgMLST completeness, as well as depth and breadth of coverage were the parameters that impacted most on cgMLST precision (i.e. identical alleles against reference circular genomes). All workflows performed well at ≥40X of depth of coverage, with high loci detection (> 99.54% for all, except for BioNumerics with 97.78%) and showed consistent cluster definitions using the reference cut-off of ≤7 allele differences. Conclusions This highlights that bioinformatics workflows dedicated to cgMLST allele calling are largely robust when paired-end reads are of high quality and when the sequencing depth is ≥40X.

Abstract
We studied 11 cases of culture-proven Listeria-associated lymphadenitis reported to the French National Reference Center for Listeria from 1994 to 2019 and 8 additional published cases. Listeria-associated lymphadenitis is rare, but it is associated with a mortality as high as for invasive listeriosis, and it is frequently diagnosed with concomitant neoplasia.

Abstract
Studies have shown that ruminants constitute reservoirs of Listeria monocytogenes, but little is known about the epidemiology and genetic diversity of this pathogen within farms. Here we conducted a large-scale longitudinal study to monitor Listeria spp. in 19 dairy farms during three consecutive seasons (N = 3251 samples). L. innocua was the most prevalent species, followed by L. monocytogenes. Listeria monocytogenes was detected in 52.6% of farms and more frequently in cattle (4.1%) and sheep (4.5%) than in goat farms (0.2%). Lineage I accounted for 69% of L. monocytogenes isolates. Among animal samples, the most prevalent sublineages (SL) and clonal complexes (CC) were SL1/CC1, SL219/CC4, SL26/CC26 and SL87/CC87, whereas SL666/CC666 was most prevalent in environmental samples. Sixty-one different L. monocytogenes cgMLST types were found, 28% common to different animals and/or surfaces within the same farm and 21% previously reported elsewhere in the context of food and human surveillance. Listeria monocytogenes prevalence was not affected by farm hygiene but by season: higher prevalence was observed during winter in cattle, and during winter and spring in sheep farms. Cows in their second lactation had a higher probability of L. monocytogenes faecal shedding. This study highlights dairy farms as a reservoir for hypervirulent L. monocytogenes.

Abstract
The bacterial foodborne pathogen Listeria monocytogenes clonal complex 1 (Lm-CC1) is the most prevalent clonal group associated with human listeriosis and is strongly associated with cattle and dairy products. Here, we analyze 2021 isolates collected from 40 countries, covering Lm-CC1 first isolation to present days, to define its evolutionary history and population dynamics. We show that Lm-CC1 spread worldwide from North America following the Industrial Revolution through two waves of expansion, coinciding with the transatlantic livestock trade in the second half of the 19th century and the rapid growth of cattle farming and food industrialization in the 20th century. In sharp contrast to its global spread over the past century, transmission chains are now mostly local, with limited inter- and intra-country spread. This study provides an unprecedented insight into L. monocytogenes phylogeography and population dynamics and highlights the importance of genome analyses for a better control of pathogen transmission.

Abstract
Listeria genus comprises two pathogenic species, L. monocytogenes (Lm) and L. ivanovii, and non-pathogenic species. All can thrive as saprophytes, whereas only pathogenic species cause systemic infections. Identifying Listeria species' respective biotopes is critical to understand the ecological contribution of Listeria virulence. In order to investigate the prevalence and abundance of Listeria species in various sources, we retrieved and analyzed 16S rRNA datasets from MG-RAST metagenomic database. 26% of datasets contain Listeria sensu stricto sequences, and Lm is the most prevalent species, most abundant in soil and host-associated environments, including 5% of human stools. Lm is also detected in 10% of human stool samples from an independent cohort of 900 healthy asymptomatic donors. A specific microbiota signature is associated with Lm faecal carriage, both in humans and experimentally inoculated mice, in which it precedes Lm faecal carriage. These results indicate that Lm faecal carriage is common and depends on the gut microbiota, and suggest that Lm faecal carriage is a crucial yet overlooked consequence of its virulence.

Abstract
Abstract
Background
Assuring informal carers' quality of life (QoL) must be a priority for public health policies and practices. The Adult Carer Quality of Life Questionnaire (AC-QoL) is a recent and valid instrument, overpassing limitations of previous tools, and being already used among informal stroke carers. This study aimed to assess the feasibility, reliability and validity of the AC-QoL among Portuguese informal carers of stroke survivors.
Methods
The linguistic adaptation of the AC-QoL was performed. Informal carers (n = 212) of stroke survivors hospitalized between September 2018 and August 2019 in all Stroke Units of the North of Portugal (n = 12) were invited to participate, 18 to 24 months post-stroke. Data on sociodemographic characteristics, psychological profile, burden and QoL were collected using a structured questionnaire. The psychometric properties of the AC-QoL were investigated through exploratory and confirmatory factor analyses. Cronbach's alpha was used to measure internal consistency. Construct validity was assessed through the association of the overall score of AC-QoL with anxiety and depressive symptoms, burden and sociodemographic characteristics.
Results
Exploratory factor analysis supported the original eight-factor structure of the AC-QoL, revealing an adequate goodness of fit to the study sample (X2(674)=1145.926; CFI=0.916; TLI=0.908; RMSEA=0.058). The AC-QoL showed a high degree of reliability, with Cronbach's scores for the subscales ranging from 0.64 to 0.97 and a Cronbach's alpha of 0.91 for the overall score. Anxiety symptoms (p < 0.001), depression symptoms (p < 0.001) and burden (p < 0.001) were inversely associated with the overall score of AC-QoL. Younger (p = 0.032) and employed (p = 0.021) informal carers presented more frequently higher scores of overall QoL, than those older and unemployed.
Conclusions
The Portuguese version of the AC-QoL is a comprehensive, simple, reliable and valid instrument to assess informal stroke carers' QoL.
Key messages
The Portuguese version of the AC-QoL is a comprehensive and valid instrument with a high degree of reliability, that can be briefly and easily applied to informal carers of stroke survivors. A comprehensive and brief assessment of informal carers’ QoL will contribute to devise strategies to promote well-being and social integration of stroke survivors and their informal carers.

Abstract
Abstract
Background
Knowledge on the processes of adaptation and learning after stroke are scarce, hindering the development of evidence-based public health strategies to promote survivors and family carers' health and wellbeing, across the post stroke trajectory. This study aims to assess the available evidence on the processes of adaptation and learning after stroke, by mapping the main barriers and enablers according to the perspectives of stroke survivors and family carers.
Methods
A scoping review was performed, following PRISMA-ScR guidelines. The electronic databases PubMed, ISI Web of Science, PsycINFO and SciELO were searched for empirical, peer-reviewed, original, and full-length studies on the processes of adaptation and learning of stroke survivors and family carers, in March 2021. Eligibility and data extraction were conducted by two independent researchers. The main qualitative data were explored by thematic content analysis and quantitative findings were synthesized.
Results
The included studies, 29 qualitative and 1 quantitative, were published between 1994 and 2019. Most of the studies were carried out with small samples and without a specific focus on the adaptation and learning processes after stroke. Barriers and enablers to stroke adaptation and learning processes were influenced by physical, psychological and social characteristics. The poor physical and functional status of survivors, the inability to maintaining the Activities of Daily Living, emotional disturbances, lack of support and information, and changes in roles, were identify as main barriers to stroke adaptation. Using coping strategies and having psychological, educational, and financial support were described as enablers.
Conclusions
Public health policies and practices should consider the physical, psychological and social barriers and enablers to the stroke adaptation and learning processes to ensure a high-quality long-term care centred on survivors and family carers.
Key messages
Robust theoretical and methodological studies, specifically designed to deeply explore and describe the post stroke adaptation and learning processes, are needed. Understand the main barriers and enablers to adaptation and learning after stroke may be useful for developing health education interventions centred on survivors and carers preferences and needs.

Abstract
Abstract
Background
Severity of disease scoring systems, namely the Simplified Acute Physiology Score (SAPS) and Acute Physiology and Chronic Health Evaluation (APACHE), are widely used to predict mortality in Intensive Care Units (ICU). Yet, neither score includes chronic HF in their model. We aimed to evaluate whether these scores perform well in risk prediction of death of patients previously diagnosed with heart failure (HF).
Methodology
This is a single-center retrospective cohort of patients admitted to an ICU in 2019. Those whose admission lasted <24 hours were excluded from analysis. The SAPS II and APACHE II scores were calculated using data from the first 24 hours of ICU admission, imputing the worst variable obtained within this timeframe. HF was defined according to the ESC recommendations. In order to assess the performance of the scores, Receiver Operating Characteristic (ROC) Curves were used to predict the risk of death in ICU in HF compared to the non-HF population.
Results
A total of 267 patients were hospitalized in ICU for a period over 24 hours in 2019 (mean age 67±16 years; 58.8% males; 21.7% with chronic HF; 33.7% admitted for sepsis). Compared to patients without HF, those with chronic HF were older (74±13 vs. 65±16 years; p<0.001) and had higher risk scores (mean SAPS II: 43.2±21.7 vs. 56.5±20.7; p<0.001; mean APACHE II: 19.8±10.0 vs. 25.1±10.0; p<0.001). Moreover, these patients were at higher risk of meaningful events during hospitalization (e.g. acute kidney injury: 38.0 vs. 66.1%; p<0.001; shock at any time: 52.4 vs. 67.8%; p=0.036). Furthermore, patients with HF had a trend towards higher mortality rates in ICU (17.3 vs. 28.8%; p=0.051) and a significantly higher death in overall hospitalization (30.8 vs. 45.8%; p=0.032). ROC curves performed well in predicting the risk of ICU death regardless of HF (SAPS II – AUC 0.78 vs. 0.81; p=0.36; APACHE II – AUC 0.75 vs. 0.78; p=0.37).
Conclusion
Approximately 1 in every 4 patients admitted to the ICU had chronic HF. Traditional risk scoring systems (SAPS II and APACHE II) performed well regardless of HF. While these results are reassuring as far as risk stratification accuracy is concerned, HF patients remained at a higher risk for worse outcomes. Therefore, prognostic tools with a therapeutic clinical applicability are urgently needed to improve the outcome of this population.

Abstract
CONTEXT Listeriosis is caused by the foodborne pathogen Listeria monocytogenes. It can present as a maternal-neonatal infection. We implemented the nationwide prospective cohort MONALISA and analyzed the features of neonatal listeriosis. METHODS We studied all neonates born alive from mothers with microbiologically-proven maternal-neonatal listeriosis enrolled from November 2009 to December 2017. We analyzed presentation, neonatal outcome at discharge and predictors of severe presentation and outcome. The study is registered at clinicaltrials.gov (NCT01520597). RESULTS We studied 189 infants. 133/189 (70%) had abnormal clinical status at birth, including acute respiratory distress in 106/189 (56%). 132/189 (70%) infants developed early-onset listeriosis and 12/189 (6%) late onset listeriosis who all presented with acute meningitis. 17/189 (9%) had major adverse outcomes: 3% death (5/189), 6% (12/189) severe brain injury, 2% (3/189) severe bronchopulmonary dysplasia, 15/17 in infants born < 34 weeks of gestation (p < 0.0001 versus infants born ≥ 34 weeks of gestation). Maternal antimicrobial treatment ≥ 1 day before delivery was associated with a significant decrease of infants' severity (resulting in significantly less inotropic drugs, fluid resuscitation, or mechanical ventilation requirement), OR 0.23 [95% confidence interval CI 0.09-0.51], p < 0.0001). CONCLUSION Antenatal maternal antimicrobial treatment is associated with reduced neonatal listeriosis severity, justifying the prescription of preemptive maternal antimicrobial therapy when maternal-fetal listeriosis is suspected. Neonatal outcome is better than reported earlier, and its major determinant is gestational age at birth.

Abstract
Introduction Any outbreak of pandemic dimension will most likely produce a serious amount of distress and prejudice to anyone, in particular when it comes to mental health. The pandemic impact in primary care and in the psychiatric emergency department are some of the topics discussed in this review. Objectives It aims to review, evaluate and reflect over the impact of a deadly coronavirus pandemic on mental health, as well as presenting possible long-term challenges and potential ways to approach it. Methods A non-systematic literary review was performed on the Pubmed, PsycInfo and Cochrane databases using the key words “covid-19”, “psychiatry”, “self-isolation” and “telepsychiatry”. Results Globally and, as expected, there has been a general increase in need for psychiatric assessment and treatment due to the COVID-19 pandemic. Conclusions The role of psychiatry has faced quite some challenges in such a short period of time: the rise of telepsychiatry; the management of patients with both a psychiatric disorder and an infection with the new coronavirus and the need to provide an adequate psychiatric assistance in the emergency room has become the new normal.

Abstract
IntroductionThe link between autism spectrum disorder (ASD) and anorexia nervosa (AN) firstly emerged in the 80’s. Given the overlap in behavioural and cognitive features between these two seemingly different disorders, AN has been hypothesized to be a female phenotype of ASD.ObjectivesThis report aims to describe a clinical case of an anorexic female patient diagnosed later in life with ASD, while presenting a bibliographic review on the subject.MethodsAfter gaining consent, detailed information about the case history was collected and medical records were analysed and reviewed. A non-systematic literary review was performed on the Pubmed and Cochrane databases using the key words “anorexia nervosa”, “females”, “comorbidity” and “autism spectrum disorder”.ResultsThe current case report is of a 28-year-old female, whose extremely low body weight and complete food refusal for three days prompted her first hospitalization in a psychiatric unit with the admission diagnosis of anorexia nervosa. However, long-term impairments in social interaction and flexibility, emotional difficulties and sensory processing overload were acknowledged and the primary diagnosis of ASD was then considered.ConclusionsAs illustrated in this case, the diagnosis of ASD should always be considered in females with eating disorders, in particular AN, regardless of age. As this neurodevelopmental condition appears to present differently in females, they also seem more likely to go underdiagnosed. Also, due to poorer treatment outcomes in females with both ASD and AN, the importance of developing a specialized approach and prompt referral of these patients is highlighted.DisclosureNo significant relationships.

Abstract
In the context of a study on the occurrence of Listeria species in an animal farm environment in Valencia, Spain, six Listeria-like isolates could not be assigned to any known species. Phylogenetic analysis based on the 16S rRNA gene and on 231 Listeria core genes grouped these isolates in a monophyletic clade within the genus Listeria, with highest similarity to Listeria thailandensis. Whole-genome sequence analyses based on in silico DNA-DNA hybridization, the average nucleotide blast and the pairwise amino acid identities against all currently known Listeria species confirmed that these isolates constituted a new taxon within the genus Listeria. Phenotypically, these isolates differed from other Listeria species mainly by the production of acid from inositol, the absence of acidification in presence of methyl α-d-glucoside, and the absence of α-mannosidase and nitrate reductase activities. The name Listeria valentina sp. nov. is proposed for this novel species, and the type strain is CLIP 2019/00642T (=CIP 111799T=DSM 110544T).

Abstract
Abstract
Introduction
Diabetes Mellitus (DM) is one of the main risk factors for cardiovascular disease (CVD). Guidelines on the use of acetylsalicylic acid (ASA) for primary prevention of CVD in this population are conflicting. A potential reduction in the severity of a first episode of Acute Myocardial Infarction (AMI) could be seen has an additional argument for the use of ASA in primary prevention. Aim: To evaluate the impact of prior intake of ASA on the presentation, severity and short-term prognosis of AMI in diabetic patients without history of CVD.
Methods
Retrospective analysis of diabetic patients without previous evidence of CVD diagnosed with type 1 AMI between January 2002 and December 2018, inserted in a multicentric registry of acute coronary syndromes. Patients were dichotomized according to whether or not they were taking ASA prior to the index event. Groups were compared according to clinical, analytical and imaging endpoints.

A total of 2596 patients were included, predominantly men (66.4%), with a mean age of 68±12 years old. Patients on ASA (19.7%) were significantly older (71±10 vs. 67±12, p<0.001) and had a higher prevalence of hypertension (89.2% vs 77.9%, p<0.001), dyslipidaemia (69.8% vs. 61.1%, p<0.001) and chronic kidney disease (10.6% vs. 4.9%, p<0.001). Overall, there was a lower prevalence of AMI with ST-segment elevation (36.5% vs. 50.8%, p<0.001) in patients on ASA. However, the same group of patients had a significantly higher probability of evolution in Killip class > I (25.4% vs. 17.0%, p<0.001), a higher median BNP elevation (315 [126–623] vs. 166 [64–431], p<0.001); and a lower average ejection fraction upon discharge (49.0±12 vs. 51±12, p=0.011). Patients on prior regular intake of ASA also had a higher prevalence of multivessel disease (38.4% vs. 28.9%, p<0.001) and multiple significant stenosis (70.2% vs. 61.7%, p<0.001). There was no significant difference regarding the percentage of electrical complications (2.3% vs. 1.2%, p=0.06), use of intra-aortic balloon pump (1.0 vs. 0.9%, p=0.74) and in-hospital death (3.0% vs. 2.4%, p=0.46). In a logistic regression model adjusted for age, sex, comorbidities and previous medication as variates, prior ASA intake was an independent predictor of a lower rate of AMI with ST-segment elevation (ExpB −0.34; 95% CI: 0.57–0.89; p=0.003). On the contrary, when adjusted to these variables, prior ASA intake was not an independent predictor of higher BNP (p=0.13) or higher probability of multivessel disease (p=0.22) or presence of ≥1 significant stenosis (p=0.31).
Conclusions
In this population of diabetic patients with a first episode of ACS, prior use of ASA in the context of primary prevention was associated with a significant lower rate of ST-segment elevation myocardial infarction.

Abstract
Listeria monocytogenes is one of the major foodborne pathogens. Isolates of PCR-serogroups IIb (n = 17) and IVb (n = 31) recovered from food (n = 33) and food processing environment (n = 15) in Poland were characterized using whole genome sequencing. Most isolates belonged to Multi-Locus Sequence Type (MLST) ST2 (31.3%) and ST5 (22.9%). Core genome MLST (cgMLST) analysis classified isolates into seven sublineages (SL) and 25 different cgMLST types (CT). Consistent with the MLST results, most sublineages were SL2 and SL5. Eleven isolates harbored aacA4 encoding resistance to aminoglycosides, three isolates harbored emrC (n = 3) and one brcABC (n = 1) encoding tolerance to benzalkonium chloride. Isolates belonging to SL5 CT2323 carried a so far unreported inlB allele with a deletion of 141 nucleotides encoding the β-repeat sheet and partially the GW1 domain of InlB. Comparison with publicly available genome sequences from L. monocytogenes isolated from human listeriosis cases in Poland from 2004 to 2013 revealed five common CTs, suggesting a possible epidemiological link with these strains. The present study contributes to characterize the diversity of L. monocytogenes in ready-to-eat (RTE) meat and meat processing environments in Poland and unravels previously unnoticed links with clinical cases in Europe.

Abstract
Understanding the role of the microbiota components in either preventing or favoring enteric infections is critical. Here, we report the discovery of a Listeria bacteriocin, Lmo2776, which limits Listeria intestinal colonization. Oral infection of conventional mice with a Δlmo2776 mutant leads to a thinner intestinal mucus layer and higher Listeria loads both in the intestinal content and deeper tissues compared to WT Listeria. This latter difference is microbiota dependent, as it is not observed in germ-free mice. Strikingly, it is phenocopied by pre-colonization of germ-free mice before Listeria infection with Prevotella copri, an abundant gut-commensal bacteria, but not with the other commensals tested. We further show that Lmo2776 targets P. copri and reduces its abundance. Together, these data unveil a role for P.copri in exacerbating intestinal infection, highlighting that pathogens such as Listeria may selectively deplete microbiota bacterial species to avoid excessive inflammation. L. monocytogenes secretes a bacteriocin (Lmo2776) homologous to the lactococcin 972 Lmo2776 controls Listeria intestinal colonization in a microbiota-dependent manner Lmo2776 targets the abundant gut commensal Prevotella copri Presence of P. copri exacerbates infection

Abstract
Abstract
Echocardiography (echo) remains the first-line imaging modality for the evaluation of cardiac masses. Three-dimensional (3D) echo, either transthoracic or transesophageal (TTE and TEE respectively), has allowed for better definition imaging, providing more information about the size, mobility, attachment and relation of these lesions with cardiac structures. Nevertheless, due to its superior tissue characterization capability, other imaging techniques, such as cardiac magnetic resonance (CMR), are very helpful in the differential diagnosis, making multimodality imaging the most attractive option for the study of intracardiac masses.
We present the case of a 85 year-old male, with paroxysmal atrial fibrillation (under effective anticoagulation), type 2 diabetes mellitus, hypertension, referred for the study of an asymptomatic cardiac mass found in a routine TTE. There were no relevant findings on physical examination. The TTE showed a bilobar spheroid mass, in the right atrium, attached to the interatrial septum, with 33x23mm and regular edges. A 3D TEE was performed confirming the previous findings, but also showing extension of this mass through the fossa ovalis membrane, reaching the left atrium; this aspect raised the doubt about either protrusion or invasion of the left atrium and, respectively, a benign (like a myxoma) versus malignant behaviour (such as a sarcoma). To better characterize this lesion, a CMR was ordered, which revealed a bilobar heterogeneous mass, attached to the right side of the interatrial septum, at the fossa ovalis membrane, without signs of adjacent tissue invasion, namely unequivocal invasion of the left atrium; it presented with intermediate T1 signal, hyperintense T2 signal and heterogeneous pattern of gadolinium enhancement, features mostly in favour of a right atrial myxoma. The complimentary study found no other relevant changes, namely no findings suggestive of endocarditis (negative blood cultures), autoimmune disease or malignancy. The patient refused undergoing heart surgery and, therefore, kept follow-up with clinical and echocardiographic stability.
Although histological examination remains the only tool for definitive diagnosis, multimodality imaging allows a quite comprehensive evaluation of intracardiac masses, enlightening the differential diagnosis. Here the imaging findings helped to establish a benign origin as the most likely, very important in this case of a probable right atrial myxoma, due to its peculiar protrusion to the left atrium through the fossa ovalis membrane.

Abstract
Advances in whole-genome sequencing (WGS) technologies have documented genetic diversity and epidemiology of the major foodborne pathogen Listeria monocytogenes (Lm) in Europe and North America, but data concerning South America are scarce. Here, we examined the population structure and genetic diversity of this major foodborne pathogen collected in Brazil. Based on core genome multilocus sequence typing (cgMLST), isolates from lineages I (n = 22; 63%) and II (n = 13; 37%) were distributed into 10 different sublineages (SLs) and represented 31 new cgMLST types (CTs). The most prevalent SLs were SL9 (n = 9; 26%), SL3 (n = 6; 17%) and SL2 and SL218 (n = 5; 14%). Isolates belonging to CTs L2-SL9-ST9-CT4420 and L1-SL315-ST520-CT4429 were collected 3 and 9 years apart, respectively, revealing long-term persistence of Lm in Brazil. Genetic elements associated with stress survival were present in 60% of isolates (57% SSI-1 and 3% SSI-2). Pathogenic islands were present in 100% (LIPI-1), 43% (LIPI-3) and 6% (LIPI-4) of the isolates. Mutations leading to premature stop codons were detected in the prfA and inlA virulence genes. This study is an important contribution to understanding the genomic diversity and epidemiology of Lm in South America. In addition, the results highlight the importance of using WGS to reveal Lm long-term persistence.

Abstract
Listeria monocytogenes is frequently found in foods and processing facilities, where it can persist, creating concerns for the food industry. Its ability to survive under a wide range of environmental conditions enhances the potential for cross-contamination of the final food products, leading to possible outbreaks of listeriosis. In this study, whole-genome sequencing (WGS) was applied as a tool to characterize and track 100 L. monocytogenes isolates collected from three food processing environments. These WGS data from environmental and food isolates were analyzed to (i) assess the genomic diversity of L. monocytogenes, (ii) identify possible source(s) of contamination, cross-contamination routes, and persistence, (iii) detect absence/presence of antimicrobial resistance-encoding genes, (iv) assess virulence genotypes, and (v) explore in vivo pathogenicity of selected L. monocytogenes isolates carrying different virulence genotypes. The predominant L. monocytogenes sublineages (SLs) identified were SL101 (21%), SL9 (17%), SL121 (12%), and SL5 (12%). Benzalkonium chloride (BC) tolerance-encoding genes were found in 62% of these isolates, a value that increased to 73% among putative persistent subgroups. The most prevalent gene was emrC followed by bcrABC, qacH-Tn6188, and qacC. The L. monocytogenes major virulence factor inlA was truncated in 31% of the isolates, and only one environmental isolate (L. monocytogenes CFS086) harbored all major virulence factors, including Listeria pathogenicity island 4 (LIPI-4), which has been shown to confer hypervirulence. A zebrafish embryo infection model showed a low (3%) embryo survival rate for all putatively hypervirulent L. monocytogenes isolates assayed. Higher embryo survival rates were observed following infection with unknown virulence potential (20%) and putatively hypovirulent (53 to 83%) L. monocytogenes isolates showing predicted pathogenic phenotypes inferred from virulence genotypes.IMPORTANCE This study extends current understanding of the genetic diversity among L. monocytogenes from various food products and food processing environments. Application of WGS-based strategies facilitated tracking of this pathogen of importance to human health along the production chain while providing insights into the pathogenic potential for some of the L. monocytogenes isolates recovered. These analyses enabled the grouping of selected isolates into three putative virulence categories according to their genotypes along with informing selection for phenotypic assessment of their pathogenicity using the zebrafish embryo infection model. It has also facilitated the identification of those isolates with genes conferring tolerance to commercially used biocides. Findings from this study highlight the potential for the application of WGS as a proactive tool to support food safety controls as applied to L. monocytogenes.

Abstract
We present the LiSEQ (Listeria SEQuencing) project, funded by the European Food Safety Agency (EFSA) to compare Listeria monocytogenes isolates collected in the European Union from ready-to-eat foods, compartments along the food chain (e.g. food-producing animals, food-processing environments) and humans. In this article, we report the molecular characterization of a selection of this data set employing whole-genome sequencing analysis. We present an overview of the strain diversity observed in different sampled sources, and characterize the isolates based on their virulence and resistance profile. We integrate into our analysis the global L. monocytogenes genome collection described by Moura and colleagues in 2016 to assess the representativeness of the LiSEQ collection in the context of known L. monocytogenes strain diversity.

Abstract
Sub-fertility fertility in bulls decreases the efficiency and profitability of cattle production because AI allows a single bull to inseminate thousands of cows. In recent decades, there has been a general decline in fertility of bulls, even among those exhibiting normal sperm motility and morphology. Despite advances in technology and knowledge, molecular, cellular and physiological mechanisms underlying the causes of low fertility in bulls are currently unclear. Therefore, the objective of this study was to identify sperm metabolites associated with fertility in Holstein bulls. The metabolome of sperm from 10 mature bulls with high fertility (HF, n=5) and low fertility (LF, n=5) was identified by gas chromatography coupled to mass spectrometry. Bull fertility was based on the sire conception rates deviating from the average. Statistical analysis was performed by using MetaboAnalyst 3.0 (http://www.metaboanalyst.ca/). A total of 22 metabolites were detected and categorized according to their major chemical classes, including amino acids, peptides/analogues, carbohydrates/carbohydrate conjugates, fatty acids, steroids/steroid derivatives, keto acids and derivatives, carboxylic acids, and other organic and inorganic compounds. Organic acids and derivatives as well as fatty acids were the major compounds in bull spermatozoa. Seven organic acids and derivatives were detected, including benzoic acid, carbonate, carbamate dimethyl, carbamate trimethyl, lactic acid, oxalic acid, and urea. Five fatty acids were identified including oleic acid, oleanitrile, nonanoic acid, and palmitic acid. Oleic acid, phosphoric acid, phosphine, carbamate trimethyl, and glycerol were the most abundant metabolites in bull sperm, whereas benzoic acid, acetic acid, l-serine, carbamate, and 2-ketobutyric acid were the least predominant metabolites present in bull sperm. Multivariate analysis (partial least squares-discriminant analysis) of the sperm metabolome showed a clear separation between HF and LF bulls. Variable importance in projection (VIP) score demonstrated that metabolites with VIP >1.5 were gamma-aminobutyric acid (VIP=2.01), carbamate trimethyl (VIP=1.88), benzoic acid (VIP=1.86), and lactic acid (VIP=1.81). Abundance ratios of gamma-aminobutyric acid, carbamate trimethyl, benzoic acid, and lactic acid was greater in HF bulls compared with LF animals. According to univariate analysis, abundance ratios of gamma-aminobutyric acid (P=0.03) and carbamate trimethyl (P=0.047) were greater in HF than in LF bulls. Gamma-aminobutyric acid was positively correlated with carbamate trimethyl (r=0.94; P<0.0001) and benzoic acid (r=0.74; P=0.0139). Benzoic acid was positively correlated with carbamate trimethyl (r=0.75; P=0.0107) and carbamate dimethyl (r=0.68; P=0.0274). The identified metabolites can serve as potential markers to evaluate semen quality and predict bull fertility.

Abstract
During a screening of Listeria species in food samples in Thailand, a Listeria-like bacterium was recovered from fried chicken and could not be assigned to any known species. Phylogenetic analysis based on the 16S rRNA gene and on 243 Listeria core genes placed the novel taxon within the Listeria aquatica, Listeria floridensis, Listeria fleishmannii and Listeria costaricensis clade (Listeria sensu lato), with highest similarity to L. floridensis (98.9 %) and L. costaricensis (98.8 %). Whole-genome sequence analyses based on the average nucleotide blast identity (ANI<86 %), the pairwise amino acid identity (AAI>64 %) and on the percentage of conserved proteins (POCP>77 %) with currently known Listeria species confirmed that the strain constituted a new taxon within the genus Listeria. At the phenotypical level, it differs from other Listeria species by the production of acid from d-tagatose and inositol. The name Listeria thailandensis sp. nov. is proposed for the novel species, and is represented by the type strain CLIP 2015/00305T (=CIP 111635T=DSM 107638T).

Abstract
Elucidating the relationships between antimicrobial resistance and virulence is key to understanding the evolution and population dynamics of resistant pathogens. Here, we show that the susceptibility of the gram-positive bacterium Listeria monocytogenes to the antibiotic fosfomycin is a complex trait involving interactions between resistance and virulence genes and the environment. We found that a FosX enzyme encoded in the listerial core genome confers intrinsic fosfomycin resistance to both pathogenic and non-pathogenic Listeria spp. However, in the genomic context of the pathogenic L. monocytogenes, FosX-mediated resistance is epistatically suppressed by two members of the PrfA virulence regulon, hpt and prfA, which upon activation by host signals induce increased fosfomycin influx into the bacterial cell. Consequently, in infection conditions, most L. monocytogenes isolates become susceptible to fosfomycin despite possessing a gene that confers high-level resistance to the drug. Our study establishes the molecular basis of an epistatic interaction between virulence and resistance genes controlling bacterial susceptibility to an antibiotic. The reported findings provide the rationale for the introduction of fosfomycin in the treatment of Listeria infections even though these bacteria are intrinsically resistant to the antibiotic in vitro.

Abstract
Background and aimThe trend in reported case counts of invasive Listeria monocytogenes (Lm), a potentially severe food-borne disease, has been increasing since 2008. In 2015, 2,224 cases were reported in the European Union/European Economic Area (EU/EEA). We aimed to validate the microbiological and epidemiological aspects of an envisaged EU/EEA-wide surveillance system enhanced by routine whole genome sequencing (WGS). Methods: WGS and core genome multilocus sequence typing (cgMLST) were performed on isolates from 2,726 cases from 27 EU/EEA countries from 2010-15. Results: Quality controls for contamination, mixed Lm cultures and sequence quality classified nearly all isolates with a minimum average coverage of the genome of 55x as acceptable for analysis. Assessment of the cgMLST variation between six different pipelines revealed slightly less variation associated with assembly-based analysis compared to reads-based analysis. Epidemiological concordance, based on 152 isolates from 19 confirmed outbreaks and a cluster cutoff of seven allelic differences, was good (sensitivity > 95% for two cgMLST schemes of 1,748 and 1,701 loci each; PPV 58‒68%). The proportion of sporadic cases was slightly below 50%. Of remaining isolates, around one third were in clusters involving more than one country, often spanning several years. Detection of multi-country clusters was on average several months earlier when pooling the data at EU/EEA level, compared with first detection at national level. Conclusions: These findings provide a good basis for comprehensive EU/EEA-wide, WGS-enhanced surveillance of listeriosis. Time limits should not be used for hypothesis generation during outbreak investigations, but should be for analytical studies.

Abstract
In August 2017, an outbreak of six listeriosis cases in Denmark was traced to cold-smoked salmon, using epidemiological investigations and whole-genome sequencing (WGS) analyses. Exchange of genome sequences allowed identification in France of a food isolate from a salmon-derived product and a human isolate from 2016 within the same cgMLST cluster as the Danish isolates (L2-SL8-ST8-CT771). The salmon product came from a third European Union country. WGS can rapidly link human cases and food isolates across Europe.

Abstract
A bacterial strain isolated from a food processing drainage system in Costa Rica fulfilled the criteria as belonging to the genus Listeria, but could not be assigned to any of the known species. Phylogenetic analysis based on the 16S rRNA gene revealed highest sequence similarity with the type strain of Listeria floridensis (98.7 %). Phylogenetic analysis based on Listeria core genomes placed the novel taxon within the Listeria fleishmannii, L. floridensis and Listeria aquatica clade (Listeria sensu lato). Whole-genome sequence analyses based on the average nucleotide blast identity (ANI<80 %) indicated that this isolate belonged to a novel species. Results of pairwise amino acid identity (AAI>70 %) and percentage of conserved proteins (POCP>68 %) with currently known Listeria species, as well as of biochemical characterization, confirmed that the strain constituted a novel species within the genus Listeria. The name Listeria costaricensis sp. nov. is proposed for the novel species, and is represented by the type strain CLIP 2016/00682T (=CIP 111400T=DSM 105474T).

Abstract
During 2015–2016, we evaluated the performance of whole-genome sequencing (WGS) as a routine typing tool. Its added value for microbiological and epidemiologic surveillance of listeriosis was compared with that for pulsed-field gel electrophoresis (PFGE), the current standard method. A total of 2,743 Listeria monocytogenes isolates collected as part of routine surveillance were characterized in parallel by PFGE and core genome multilocus sequence typing (cgMLST) extracted from WGS. We investigated PFGE and cgMLST clusters containing human isolates. Discrimination of isolates was significantly higher by cgMLST than by PFGE (p<0.001). cgMLST discriminated unrelated isolates that shared identical PFGE profiles and phylogenetically closely related isolates with distinct PFGE profiles. This procedure also refined epidemiologic investigations to include only phylogenetically closely related isolates, improved source identification, and facilitated epidemiologic investigations, enabling identification of more outbreaks at earlier stages. WGS-based typing should replace PFGE as the primary typing method for L. monocytogenes.

Abstract
Listeria monocytogenes (Lm) is a major human foodborne pathogen. Numerous Lm outbreaks have been reported worldwide and associated with a high case fatality rate, reinforcing the need for strongly coordinated surveillance and outbreak control. We developed a universally applicable genome-wide strain genotyping approach and investigated the population diversity of Lm using 1,696 isolates from diverse sources and geographical locations. We define, with unprecedented precision, the population structure of Lm, demonstrate the occurrence of international circulation of strains and reveal the extent of heterogeneity in virulence and stress resistance genomic features among clinical and food isolates. Using historical isolates, we show that the evolutionary rate of Lm from lineage I and lineage II is low (∼2.5 × 10-7 substitutions per site per year, as inferred from the core genome) and that major sublineages (corresponding to so-called 'epidemic clones') are estimated to be at least 50-150 years old. This work demonstrates the urgent need to monitor Lm strains at the global level and provides the unified approach needed for global harmonization of Lm genome-based typing and population biology.

Abstract
The aim of the present study was to evaluate: (1) the presence of nerve growth factor (NGF), neurotrophic tyrosine kinase receptor 1 (NTRK1), and nerve growth factor receptor (NGFR) in the rabbit uterus; and (2) the in vitro effects of NGF on PGF2α and PGE2 synthesis and on the PGE2-9-ketoreductase (PGE2-9-K) activity by the rabbit uterus. Nerve growth factor, NTRK1, and NGFR were immunolocalized in the luminal and glandular epithelium and stroma cells of the endometrium. reverse transcriptase polymerase chain reaction indicated the presence of messenger RNA for NGF, NTRK1, and NGFR in the uterus. Nerve growth factor increased (P < 0.01) in vitro secretions of PGF2α and PGE2 but coincubation with either NTRK1 or oxide nitric synthase (NOS) inhibitors reduced (P < 0.01) PGF2α production and blocked (P < 0.01) PGE2 secretion. Prostaglandins releases were lower (P < 0.01) than control when uterine samples were treated with NGF plus cyclooxygenase inhibitor. However, addition of NGFR inhibitor reduced (P < 0.01) PGF2α secretion less efficiently than NTRK1 or NOS inhibitors but had no effect on PGE2 yield. Nerve growth factor increased (P < 0.01) the activity of PGE2-9-K, whereas coincubation with NTRK1 or NOS inhibitors abolished (P < 0.01) this increase in PGE2-9-K activity. However, cotreatment with either cyclooxygenase or NGFR inhibitors had no effect on PGE2-9-K activity. This is the first study to document the distribution of NGF/NTRK1 and NGFR systems and their effects on prostaglandin synthesis in the rabbit uterus. NGF/NTRK1 increases PGF2α and PGE2 productions by upregulating NOS and PGE2-9-K activities, whereas NGF/NGFR augments only PGF2α secretion, through an intracellular mechanism that is still unknown.

Abstract
The aim of this work was to evaluate the predictors of mortality in a group of end-stage kidney disease (ESRD) patients under dialysis, by performing a three-year follow-up study. From the 236 patients included in this study, 54 patients died during the three-year follow-up period. Our data showed that the risk of death was higher in patients presenting lower levels of mean cell hemoglobin concentration, transferrin, and albumin. Our study showed that poor nutritional status and an inflammatory-induced iron depleted erythropoiesis are important factors for mortality in these patients.

Abstract
This work aimed to evaluate how aging could influence patients' perception of health quality of life (HRQOL), as well as, the effect of aging on dialysis adequacy and in hematological, iron status, inflammatory and nutritional markers. In this transversal study were enrolled 305 ESRD patients under online-hemodiafiltration (OL-HDF) (59.67% males; 64.9 ± 14.3 years old). Data about comorbidities, hematological data, iron status, dialysis adequacy, nutritional and inflammatory markers were collected from patient's records. Moreover, HRQOL score, by using the Kidney Disease Quality of Life-Short Form (KDQOL-SF), was assessed. Analyzing the results according to quartiles of age, significant differences were found for some parameters evaluated by the KDQOL-SF instrument, namely for work status, physical functioning and role-physical, which decreased with increasing age. We also found a higher proportion of diabetic patients, a decrease in creatinine, iron, albumin serum levels, transferrin saturation and nPCR, with increasing age. Moreover, significant negative correlations were found between age and mean cell hemoglobin concentration, iron, transferrin saturation, albumin, nPCR, work status, physical functioning and role-physical. In conclusion, our results showed that aging is associated with a decreased work status, physical functioning and role-physical, with a decreased dialysis adequacy, iron availability and nutritional status, and with an increased proportion of diabetic patients and of patients using central venous catheter, as the vascular access. The knowledge of these changes associated with aging, which have impact in the quality of life of the patients, could be useful in their management.

Abstract
AIMS The effects of irradiation (gamma-rays and electron-beams), up to 10 kGy, in the antimicrobial activity of mushroom species (Boletus edulis, Hydnum repandum, Macrolepiota procera and Russula delica) differently processed (fresh, dried, freeze) were evaluated. METHODS AND RESULTS Clinical isolates with different resistance profiles from hospitalized patients in Local Health Unit of Mirandela, Northeast of Portugal, were used as target micro-organisms. The mushrooms antimicrobial activity did not suffer significant changes that might compromise applying irradiation as a possible mushroom conservation technology. CONCLUSIONS Two kGy dose (independently of using gamma-rays or electron-beams) seemed to be the most suitable choice to irradiate mushrooms. SIGNIFICANCE AND IMPACT OF THE STUDY This study provides important results in antimicrobial activity of extracts prepared from irradiated mushroom species.
