Abstract
Microbial diversity of caves is largely understudied and its possible applications are still unknown. Autochthonous fungi, in particular, may have the potential to biomineralize metals and may be used as promising agents for bioremediation of polluted sites; thus, unearthing the fungal diversity in hypogean ecosystems is nowadays of utmost importance. To start addressing this knowledge gap, the cultivable mycobiota of two neighbouring caves-one natural and one exploited for touristic purposes-were characterised and compared by studying fungi isolated from sediments collected at increasing distances from the entrance. Overall, 250 fungal isolates ascribable to 69 taxa (mainly Ascomycota) were found, a high percentage of which was reported in caves for the first time. The sediments of the touristic cave displayed a richer and more diversified community in comparison with the natural one, possibly due to visitors carrying propagules or organic material. Considering that these environments are still poorly explored, chances to detect new fungal lineages are not negligible.

Abstract
Laparoscopic surgery underwent great improvements during the last few years. This review aims to compare the performance of Trainee Surgeons using 2D versus 3D/4 K laparoscopy. A systematic review of the literature was done on Pubmed, Embase, Cochrane's Library and Scopus. The following words and key phrases have been searched: "Two-dimensional vision", "Three-dimensional vision", "2D and 3D laparoscopy", "Trainee surgeons". This systematic review was reported according to the PRISMA statement 2020. PROSPERO registration No. CRD42022328045. Twenty-two randomized controlled trials (RCTs) and two observational studies were included in the systematic review. Two trials were carried out in a clinical setting, and twenty-two trials were performed in a simulated setting. In studies involving the use of a box trainer, the number of errors in the 2D laparoscopic group was significantly higher than in the 3D laparoscopic group during the performance of FLS skill tasks: peg transfer (MD: -0.82; 95% CI - 1.17 to - 0.47; p < 0.00001), cutting (MD: - 1.09; 95% CI - 1.50 to - 0.69 p < 0.00001), suturing (MD: - 0.48; 95% CI - 0.83 to - 0.13 p = 0.007), However, in clinical studies, there was no significant difference in the time taken for laparoscopic total hysterectomy (MD: 8.71; 95% CI - 13.55 to 30.98; p = 0.44) and vaginal cuff closure (MD: 2.00; 95% CI - 0.72 to - 4.72; p = 0.15) between 2D group and 3D group. 3D laparoscopy facilitates learning for novice surgeons and shows improvements in their laparoscopic performance.

Abstract
Abstract
Background
Although immunotherapies represent an encouraging approach against cancer, to date none translated to the clinical benefit in Glioblastoma (GBM). One aspect contributing to this failure is the highly immunosuppressive GBM microenvironment. Our approach to overcome immunosuppression is to increase anti-tumor immune responses via adenovirus (AdV)-mediated delivery of the MHC-II Transactivator (CIITA) gene. CIITA-induced MHC-II expression is anticipated to convert GBM cells into surrogate antigen presenting cells able to prime T helper cells, therefore promoting CD4+ and CD8+ mediated immunity.
Material and Methods
We generated AdVs containing wild type CIITA (Ad-CIITA) using a replication-defective serotype5 adenoviral backbone. AdVs containing a mutated, non-functional version of CIITA (Ad-CIITA mutant) and an empty CMV promoter (Ad-null) were used as controls. AdV-mediated MHC-II expression was monitored at mRNA, protein and cell surface level. For the functional assessment of anti-tumor immune responses, we developed an advanced human GBM organoid model system consisting of tumor organoids co-cultured with either human peripheral blood mononuclear cells (PBMCs) or isolated CD3+ T cells. T cell mediated tumor cell killing was monitored over time via live cell imaging and flow cytometry.
Results
We successfully constructed and produced a CIITA-armed AdV that induces MHC-II expression in infected GBM cells, indicating the efficient expression of transcriptionally active CIITA for at least six days post infection. In immunocompetent human GBM organoids, Ad-CIITA infection of tumor cells led to prominent organoid disruption and tumor cell death, an effect that was not observed in the absence of PBMCs or CD3+ T cells. Tumor organoids infected with Ad-CIITA mutant remained intact, demonstrating the implication of cell surface MHC-II molecules in the observed phenotype.
Conclusion
Our results demonstrate that AdV-mediated delivery of CIITA is a promising strategy to increase T cell mediated immunity against glioblastoma.

Abstract
Abstract
Background
To date, glioblastoma (GBM) remains a fatal disease, with a median overall survival of roughly over a year. There is a crucial need of new treatment options, yet most clinical trials have failed partly due to the lack of predictive preclinical model systems. Currently, most patient-derived preclinical models suffer from the reduction or absence of immune system components, which represents a bottleneck for adequate immunotherapy testing. Humanized mice offer new opportunities here, since they rebuild an adaptive human immune system in a NSG mouse. Derivation of glioblastoma patient-derived orthotopic xenografts (PDOXs) in humanized mice appears thus as a promising tool for testing new treatment strategies targeting the tumor microenvironment (TME).
Material and Methods
We derived PDOXs through intracranial implantation of GBM primary organoids in different immunocompromised mouse strains (Nude, NOD/SCID, NSG). To introduce back the adaptive human immune system, GBM PDOXs were further derived in human CD34+ hematopoietic stem cell-engrafted NSG (HU-CD34+) mice. We applied single-cell RNA-sequencing, multicolor flow cytometry, immunohistochemical analyses and functional studies to examine the heterogeneous TME in a cohort of GBM PDOX models. We further interrogated the contribution and crosstalk between the human and mouse components constituting the brain TME in HU-CD34+ PDOXs.
Results
We show that glioma PDOXs can be derived in mice of different background including Nude, NOD-SCID, NSG and HU-CD34+ mice. Mouse-derived TME created in PDOX models contains tumor-associated macrophages (TAMs) known as major immuno-suppressive components of human GBM tumors. We further show that PDOXs derived in HU-CD34+ NSG mice present human CD45+ immune cells in the bone marrow and blood. Interestingly, we detect an influx of human immune cells in tumors developed in the mouse brain, which interact with the brain-derived immunosuppressive TME of mouse origin.
Conclusion
We here provide a thorough characterization of the heterogeneous brain TME created in GBM PDOX models. We show that human GBM can instruct mouse-derived brain cells towards immune-suppressive TME. The missing adaptive immune component can be introduced by derivation of GBM PDOXs in humanized mice. Such immunocompetent in vivo models will be important for testing novel therapies targeting different immune components in GBM.

Abstract
Abstract
Introduction
The Oxford-AstraZeneca vaccine Vaxzevria is a viral-vector vaccine developed to prevent COVID-19 infection. Two doses scored 81.3% efficacy against symptomatic infection and 100% against hospitalization. In Italy, Vaxzevria use started in February. After two deaths among the Army, Italian Medicines Agency withdrawn the vaccine batch involved. News about fatal thrombosis increased, together with population concern. On March 14th, the Piedmont Region suspended another batch following a new time-related death. The following day, several European states suspended Vaxzevria administration waiting for indication from an EMA meeting on March 18th. The aim of Authors was to study the effect of suspension on adhesion among general population.
Methods
Authors registered vaccine adhesion of vaccination centers offering Vaxzevria. To access vaccination, people was requested to express willingness through a website. Then, access was granted with a summoning SMS or e-mail. Vaxzevria target populations were members of law enforcement agencies and school personnel of any age. Data from February 25th to April 12th form a Local Healthcare Unit in Piedmont Region (Italy).
Results
Vaccine adhesion ranged from 95 to 100% from February 25th to March 12th (mean 97%). During March 13th it decreased to 73%, then 48% on March 14th, the day of local withdraw of all Vaxzevria doses in Piedmont Region. Activity restarted on March 19th with a 65% of adhesion, and a mean of 75% (69-81%) in the following days. From March 24th-31th adhesion recovered, with a mean 89%. April 1st-12th recorded a plateau: 81-100%, mean 91%. From March 13th a total of 1478 people out of 8339 (17.7%) did not receive their scheduled vaccination.
Conclusions
Both news and official statements had an impact on trust and vaccine adhesion among population and dramatically slowed the COVID-19 vaccine campaign, with a possible effect on infection spreading. Further data and analysis will be provided in the following months.
Key messages
Vaxzevria temporary suspension had an impact on vaccine adhesion. Vaccine adhesion took one month to go back to previous values.

Abstract
Abstract
Background
A comprehensive understanding of the attitudes towards patient safety of the new generation of healthcare workers is fundamental not only for ensuring safe, high-quality care in the present but also for creating a safer healthcare setting in the future. This study aimed to systematically review the literature on patient safety attitudes of health professional students, new graduates, newly registered health professionals, and resident trainees, and to examine potential differences in this population with respect to year of study, specialty, and gender.
Methods
We searched four databases (i.e., PubMed, Web of Science, Scopus, and PsycInfo) up to 20/02/2020 and screened also additional sources, including weekly, automatic e-mailed search alerts up to 18/10/2020. Two reviewers independently performed all methodological steps (i.e., search, study selection, quality appraisal, data extraction and formal narrative synthesis), including a third reviewer in case of disagreement.
Results
We identified 6606 records, assessed 188 full-texts, and included 31 articles. Across studies, healthcare students and young professionals reported more positive patient safety attitudes in certain domains (e.g., teamwork climate, error inevitability, received patient safety training) but showed more negative attitudes in other areas (e.g., management support, safety climate, disclosure responsibility). Women and persons with more years of study and training demonstrated more positive attitudes towards patient safety.
Conclusions
Healthcare students should receive early curricular education in patient safety to build a solid foundation for the development of a strong and healthy safety culture. Understanding the differences in attitudes between aspiring healthcare providers from different areas is important to tailor teaching and training to the specific needs of certain populations.
Key messages
According to the reviewed literature, young healthcare students and professionals’ attitudes towards patient safety differed across domains. Institutions should increase education and training on patient safety for aspiring healthcare professionals, tailor them to the specific needs of this population, and monitor attitudes over time.

Abstract
Abstract
BACKGROUND
Numerous epidemiological studies have highlighted the protective role of immunoglobulin E-mediated allergic diseases on glioblastoma (GBM) susceptibility and prognosis. However, the mechanistic explanations behind these phenomena remain unexplored. Our objective was to set up a preclinical model and investigate the mechanisms underlying such protection to improve our understanding of the crosstalk between immune system and brain tumor development.
MATERIAL AND METHODS
A mouse model of allergic airway inflammation (AAI) induced by repeated nasal instillation of House Dust Mite extract was initiated before intracranial implantation of GL261 glioma cells, in both immunocompetent (C57BL/6) and immunodeficient (RAG-KO) mice. Tumor take and tumor growth were monitored by MRI. Central (microglia) and peripheral (spleen, bone marrow) immune cells were characterized by flow cytometry. The response of microglia was further assessed by RNA sequencing. Impact of candidate genes on patient survival was characterized by Cox regression analysis using data from TCGA and CGGA.
RESULTS
Following AAI induction in C57BL/6 mice, engraftment of GL261 cells in the brain was delayed and tumor growth rate was reduced. This correlated with an increase in survival of the mice and was accompanied by increased effector memory T-cells in the circulation. Of note, the survival benefit was lost in RAG-KO mice devoid of adaptive immunity. At the level of the brain, we observed enhanced secretion of TNFα and IL6 in microglia ex vivo. AAI induced a transcriptional reprogramming of microglia towards a pro-inflammatory-like state. We identified an allergy-related microglia gene signature that is associated with improved prognosis of glioma patients.
CONCLUSION
Our results demonstrate that AAI limits both tumor take and GBM progression in mice, providing a preclinical model to study the role of allergic inflammation in GBM susceptibility and prognosis, respectively. At the functional level, we identify a potentiation of microglial and adaptive anti-tumoral immunity. Further investigations are warranted to shed light on the reciprocal crosstalk between microglial reprogramming and peripheral immunity in the context of allergies and brain tumors.

Abstract
OBJECTIVES The COVID-19 pandemic is putting a huge strain on the provision and continuity of care. The length of sickness absence of the healthcare workers as a result of SARS-CoV-2 infection plays a pivotal role in hospital staff management. Therefore, the aim of this study was to explore the timing of COVID-19 recovery and viral clearance, and its predictive factors, in a large sample of healthcare workers. STUDY DESIGN This is a retrospective cohort study. METHODS The analysis was conducted on data collected during the hospital health surveillance programme for healthcare staff at the University Hospital of Verona; healthcare workers were tested for SARS-CoV-2 through RT-PCR with oronasopharyngeal swab samples. The health surveillance programme targeted healthcare workers who either had close contact with SARS-CoV-2-infected patients or were tested as part of the screening-based strategy implemented according to national and regional requirements. Recovery time was estimated from the first positive swab to two consecutive negative swabs, collected 24 h apart, using survival analysis for both right-censored and interval-censored data. Cox proportional hazard was used for multivariate analysis. RESULTS During the health surveillance programme, 6455 healthcare workers were tested for SARS-CoV-2 and 248 (3.8%, 95% confidence interval [CI]: 3.4-4.3) reported positive results; among those who tested positive, 49% were asymptomatic, with a median age of 39.8 years, which is significantly younger than symptomatic healthcare workers (48.2 years, P < 0.001). Screening tests as part of the health surveillance programme identified 31 (12.5%) of the positive cases. Median recovery time was 24 days (95% CI: 23-26) and 21.5 days (95% CI: 15.5-30.5) in right- and interval-censoring analysis, respectively, with no association with age, sex or presence of symptoms. Overall, 63% of participants required >20 days to test negative on two consecutive swabs. Hospitalised healthcare workers (4.8%) were older and had a significantly longer recovery time compared with non-hospitalised healthcare workers in both analyses (33.5 vs 24 days, P = 0.005). CONCLUSIONS Recovery from COVID-19 and viral clearance may take a long time, especially in individuals who are hospitalised. To detect asymptomatic cases, screening programmes for healthcare workers is recommended.

Abstract
BACKGROUND Concomitant mitral regurgitation (MR) impaired prognosis in patients undergoing transcatheter aortic valve implantation (TAVI). It has been suggested that the use of first generation self-expandable valve in patients with significant MR is associated with worse outcome as compared with balloon expandable valve. However, the impact of newer generation transcatheter devices on MR has not been investigated so far. We aim to assess the prognostic impact of MR in patients undergoing TAVI with the first-generation vs. the latest generation of self-expandable valves. METHODS We analyzed 2964 consecutive patients who underwent TAVI. Patients were classified into 4 groups according to the degree of baseline MR and the generation of self expandable valve implanted. RESULTS Of 1234 patients with moderate or severe MR, 817 were treated with first generation and 417 patients with second generation valves. Whereas, of 1730 patients with no or mild MR, 1130 were treated with first generation and 600 patients with second generation valves. Although, concomitant moderate-severe MR was found to be an independent predictor of mortality after TAVI, the use of newer generation self expandable valves was associated with higher survival rate at 1 year irrespective of the degree of preprocedural MR. At multivariable analysis the use of newer generation valve was associated with MR improvement throughout 1 year follow-up. CONCLUSION Baseline moderate-severe MR is associated with an increase in mortality after TAVI. However, the degree of preprocedural MR doesn't impact survival when a second generation self expandable valve is used.

Abstract
The aim of this study was to evaluate the impact of early treatment with corticosteroids on SARS-CoV-2 clearance in hospitalized COVID-19 patients. Retrospective analysis on patients admitted to the San Raffaele Hospital (Milan, Italy) with moderate/severe COVID-19 and availability of at least two nasopharyngeal swabs. The primary outcome was the time to nasopharyngeal swab negativization. A multivariable Cox model was fitted to determine factors associated with nasopharyngeal swab negativization. Of 280 patients included, 59 (21.1%) patients were treated with steroids. Differences observed between steroid users and non-users included the proportion of patients with a baseline PaO2/FiO2 ≤ 200 mmHg (45.8% vs 34.4% in steroids and non-steroids users, respectively; p = 0.023) or ≤ 100 mmHg (16.9% vs 12.7%; p = 0.027), and length of hospitalization (20 vs 14 days; p < 0.001). Time to negativization of nasopharyngeal swabs was similar in steroid and non-steroid users (p = 0.985). According to multivariate analysis, SARS-CoV-2 clearance was associated with age ≤ 70 years, a shorter duration of symptoms at admission, a baseline PaO2/FiO2 > 200 mmHg, and a lymphocyte count at admission > 1.0 × 109/L. SARS-CoV-2 clearance was not associated with corticosteroid use. Our study shows that delayed SARS-CoV-2 clearance in moderate/severe COVID-19 is associated with older age and a more severe disease, but not with an early use of corticosteroids.

Abstract
Elevated serum IgE levels are associated with allergic disorders, parasitosis and specific immunologic abnormalities. In addition, epidemiological and mechanistic evidence indicates an association between IgE-mediated immune surveillance and protection from tumour growth. Intriguingly, recent studies reveal a correlation between IgE deficiency and increased malignancy risk. This is the first review discussing IgE levels and links to pathological conditions, with special focus on the potential clinical significance of ultra-low serum IgE levels and risk of malignancy. In this Position Paper we discuss: (a) the utility of measuring total IgE levels in the management of allergies, parasitosis, and immunodeficiencies, (b) factors that may influence serum IgE levels, (c) IgE as a marker of different disorders, and d) the relationship between ultra-low IgE levels and malignancy susceptibility. While elevated serum IgE is generally associated with allergic/atopic conditions, very low or absent IgE may hamper anti-tumour surveillance, indicating the importance of a balanced IgE-mediated immune function. Ultra-low IgE may prove to be an unexpected biomarker for cancer risk. Nevertheless, given the early stage of investigations conducted mostly in patients with diseases that influence IgE levels, in-depth mechanistic studies and stratification of malignancy risk based on associated demographic, immunological and clinical co-factors are warranted.

Abstract
Adipositas cordis (AC) is a rare cardiomyopathy characterized by fatty infiltration of the myocardium without signs of tissue destruction or inflammation. Its diagnosis is challenging and requires histopathological examination. This study describes such cardiomyopathy in two cats that died suddenly. In both cases, anatomopathological examination showed gross lesions indicative of acute heart failure, associated with an increase in subepicardial fat, particularly in the right ventricle. Microscopically, there was an increased amount of subepicardial and intramyocardial adipose tissue in the right ventricular free wall, without signs of cellular degeneration, inflammatory infiltration, necrosis or fibrosis, confirmed by histochemical staining. AC is a rare cardiac pathology, but it should be taken into consideration in feline medicine when a sudden death occurs.

Abstract
Abstract
Background
The LEADERS FREE trial established the favourable clinical profile of a new polymer-free biolimus A9-eluting stent (PF-BES) in patients at high bleeding risk when used with a 1-month dual anti-platelet therapy (DAPT) strategy.
Purpose
This is the first study evaluating real-world reasons and outcomes for a 1-month versus longer DAPT strategies following PF-BES percutaneous coronary intervention (PCI).
Methods
FREEDOM is an all-comers registry including all patients who underwent PCI with at least one PF-BES at 10 sites, between January 2016 and July 2018. Patients were stratified according to DAPT strategy at discharge (1-month vs >1-month). Baseline features, reasons for PF-BES as reported by the treating physician, and outcomes were compared between groups. Primary outcomes were the 390-day estimates of a patient-oriented composite endpoint (POCE: death, myocardial infarction (MI) or target vessel revascularization) and of a device-oriented composite endpoint (DOCE: cardiac death, target vessel-MI or ischemia-driven target lesion revascularization). Incidence rates were adjusted for clinically relevant factors and outcome predictors. To avoid survival bias, landmark analyses starting from 1-month post-PCI were further carried.
Results
Following PF-BES PCI, 328 (40.3%) patients were discharged with 1-month DAPT and 485 (59.6%) patients with longer DAPT (median 12 months, IQR 6–12 months). Patients with hypertension or on oral anticoagulation (OAT) were more likely and patients with a previous or an index MI were less likely to be discharged on 1-month DAPT. Patients prescribed with 1-month DAPT were more likely to have had a PF-BES for a LEADERS FREE high bleeding risk criterium than those with longer DAPT (90.2% vs 69.9%, p=0.001). The same association was observed when the reason for PF-BES was a planned major surgery (13.1% vs 6.2%; p=0.001) or OAC to be continued after PCI (38.7% vs 16.5%, p<0.001). Conversely, patients with planned longer DAPT were more likely to have had a PF-BES following the operator preference (2.4% vs 15.5%, p<0.001) or for a reason other than a LEADERS FREE criterium or operator preference (5.2% vs 11.3%, p<0.001). No between-groups differences in the occurrence of the primary outcomes (1-month vs >1-month DAPT: POCE 11.9% vs 13.2%, p=0.747; adj-HR 1.29 [95% CI 0.78–2.10]; DOCE: 4.8% vs 8.1%, p=0.500; adj-HR 1.01 [95% CI 0.50–2.07]) and of bleedings (any: 11.3% vs 9.4%, p=0.472; adj-HR 0.87 [95% CI 0.51–1-50]; BARC 3–5: 4.2% vs 2.2%; p=0.108; adj-HR 1.50 [95% CI 0.58–3.87]) were observed. Landmark analyses showed similar results.
Conclusions
In a large contemporary all-comers registry, factors reflecting the operator-perceived patient high bleeding risk were the main drivers of a very-short DAPT strategy following PF-BES PCI. We found no interaction of DAPT duration with outcomes following PF-BES PCI, an observation warranting investigation in adequately powered randomised studies.

Abstract
Abstract
Background
The absence of a polymer-coat along with fast drug absorption represent the benchmark counterpart of the favourable clinical profile of a new polymer-free biolimus A9-eluting stent (PF-BES), also when used with a very short dual antiplatelet therapy (DAPT) strategy. Its current use in the real-world setting has not been thoroughly assessed.
Purpose
We evaluated contemporary patterns of indications, DAPT strategies and outcomes for the PF-BES.
Methods
FREEDOM is a multicenter registry including all patients who underwent percutaneous coronary intervention (PCI) with at least one PF-BES at 10 italian sites. Reasons for PF-BES PCI and planned antithrombotic regimen at discharge were collected. Primary outcomes were the 390-day Kaplan Meier estimates of a patient-oriented composite endpoint (POCE: death, any myocardial infarction [MI] or any target vessel revascularization [TVR]) and of a device-oriented composite endpoint (DOCE: cardiac death, target vessel-MI or ischemia-driven target lesion revascularization [ID-TLR]). The independent outcomes predictors were assessed through multivariate Cox proportional hazards analysis.
Results
Between January 2016 and July 2018, 858 patients (age: 74±10 years, 64.6% males, 58.7% acute coronary syndrome presentation) underwent PF-BES PCI. Main reasons for PF-BES physician's choice were advanced age (26.0%), oral anticoagulation (OAT) to be continued after PCI (25.3%), operator preference for PF-BES (9.9%), planned major surgery (8.6%), cancer (8.6%), anemia (7.9%) and recent bleeding (7.0%). Overall, the operator choice to implant a PF-BES reflected a perceived high bleeding risk in 77.7% of patients. At discharge, 99.2% of patients were on DAPT, 19.5% on triple therapy, and 0.8% on single antiplatelet therapy plus OAT. Planned DAPT duration was 1-month in 40.3% of patients, with 33.8% of these being on triple therapy. At 390-day follow-up (median 340 days, interquartile range: 187–390 days) the incident estimate of POCE was 13.1% (any MI 3.7%, any TVR 3.4%) and of DOCE was 7.1% (TV-MI 3.6%, ID-TLR 1.4%); while 390-day estimate of any bleeding event was 11.1% (BARC 3–5 bleeding 3.0%). Independent predictors of 390-day POCE were eGFR≤60 ml/min (HR 1.81; 95% CI 1.09–3.04, p=0.028), a history of cancer (HR 2.62; 95% CI 1.43–4.81, p=0.002) and severely calcified lesion/s (HR 2.05; 95% CI 1.09–3.85, p=0.025). Independent predictors of DOCE were a previous MI (HR 2.06; 95% CI 1.03–4.15, p=0.041), a history of cancer (HR 2.69; 95% CI 1.18–6.13, p=0.019) and bifurcation lesion/s (HR 2.66; 95% CI 1.38–5.13, p=0.004).
Conclusions
In a large, contemporary all-comers registry, the main reasons for PF-BES use reflected in most cases the operator-perceived high bleeding risk of the patient. Following PF-BES PCI, a very-short DAPT strategy was frequently implemented. The outcomes observed in this registry suggest a favorable safety and efficacy profile for the PF-BES in a real-world clinical setting.

Abstract
BACKGROUND In the last years, patients' empowerment has been increasingly recognized as a crucial dimension of patient-centered healthcare and patient safety. Nevertheless, little work has been done so far in the field of patient safety to investigate strategies for empowering psychiatric patients. Therefore, the aim of this study was to identify, by using focus groups, whether and how psychiatric patients' empowerment can improve risk management according to the perspective of healthcare providers (HPs). METHODS A mixed-method approach composed of a qualitative data collection method (i.e., focus groups) and a quantitative analysis technique (i.e., inductive content analysis) was applied. HPs working in mental health settings shared their perspectives on psychiatric patients' empowerment in risk management. After the transcription of the audio-taped discussions and the subsequent development of a hierarchical four-level coding system (strategy versus critical issue, thematic area, category, subcategory), two independent raters codified the transcripts and synthesized the content. Absolute frequencies are reported for quantitative data. RESULTS Twelve focus groups consisting of six to ten participants, each with an overall sample size of 95 participants (65 women; average age ± SD 47 ± 9 yrs), were enrolled. A total of 1252 participants' verbal contributions (i.e., units of analysis) were assessed. Strategies and critical issues (Level 1) were mentioned almost equally (52 and 48%, respectively) by the HPs. Most of the contributions at Level 2 referred to the thematic areas Treatment and Cure (69%) and Emergency Management (21%). In the area Treatment and Cure, the category Therapeutic Compliance (Level 3) was discussed in one third of all contributions. CONCLUSIONS Our results suggest that HPs consider patients as crucial partners in risk management and expect them to play a key role in actively enhancing safety. Policy makers should be aware that risk management in mental health settings particularly relies on the therapeutic relationship between HPs and patients. Therefore, allocating sufficient human and financial resources to mental health care aiming to further support the relationship between patients and HPs is of utmost importance.

Abstract
Covering 70 % of Earth, oceans are at the same time the most common and the environment least studied by microbiologists. Considering the large gaps in our knowledge on the presence of marine fungi in the oceans, the aim of this research was to isolate and identify the culturable fungal community within three species of sponges, namely Dysidea fragilis, Pachymatisma johnstonia and Sycon ciliatum, collected in the Atlantic Ocean and never studied for their associated mycobiota. Applying different isolation methods, incubation temperatures and media, and attempting to mimic the marine and sponge environments, were fundamental to increase the number of cultivable taxa. Fungi were identified using a polyphasic approach, by means of morpho-physiological, molecular and phylogenetic techniques. The sponges revealed an astonishing fungal diversity represented by 87 fungal taxa. Each sponge hosted a specific fungal community with more than half of the associated fungi being exclusive of each invertebrate. Several species isolated and identified in this work, already known in terrestrial environment, were first reported in marine ecosystems (21 species) and in association with sponges (49 species), including the two new species Thelebolus balaustiformis and Thelebolus spongiae, demonstrating that oceans are an untapped source of biodiversity.

Abstract
Environmental enrichment may slow cognitive decay possibly acting through an improvement in vascular function. Aim of the study was to assess the effects of a 7-month cognitive, social, and physical training program on cognitive and vascular function in patients with mild cognitive impairment. In a single-center, randomized, parallel-group study, 113 patients (age, 65–89 years) were randomized to multidomain training (n=55) or usual care (n=58). All participants underwent neuropsychological tests and vascular evaluation, including brachial artery flow-mediated dilation, carotid–femoral pulse wave velocity, carotid distensibility, and assessment of circulating hematopoietic CD34+ and endothelial progenitor cells. At study entry, an age-matched control group (n=45) was also studied. Compared with controls, patients had at study entry a reduced flow-mediated dilation (2.97±2.14% versus 3.73±2.06%;
P
=0.03) and hyperemic stimulus (shear rate area under the curve, 19.1±15.7 versus 25.7±15.1×10
−3
;
P
=0.009); only the latter remained significant after adjustment for confounders (
P
=0.03). Training improved Alzheimer disease assessment scale cognitive (training, 14.0±4.8 to 13.1±5.5; nontraining, 12.1±3.9 to 13.2±4.8;
P
for interaction visit×training=0.02), flow-mediated dilation (2.82±2.19% to 3.40±1.81%, 3.05±2.08% to 2.24±1.59%;
P
=0.006;
P
=0.023 after adjustment for diameter and shear rate area under the curve), and circulating hematopoietic CD34
+
cells and prevented the decline in carotid distensibility (18.4±5.3 to 20.0±6.6, 23.9±11.0 to 19.5±7.1 Pa
−1
;
P
=0.005). The only clinical predictor of improvement of cognitive function after training was established hypertension. There was no correlation between changes in measures of cognitive and vascular function. In conclusion, a multidomain training program slows cognitive decline, especially in hypertensive individuals. This effect is accompanied by improved systemic endothelial function, mobilization of progenitor CD34
+
cells, and preserved carotid distensibility.

Abstract
The sensitivity of Hemoccult testing (HO) in a population-based screening for colorectal cancer was evaluated. HO sensitivity estimates were calculated as the ratio of screen-detected HO-positives to total screen or interval-detected cancers. Sensitivity was estimated according to 1, 2, and 3-year rescreening intervals. Corresponding estimates are 69.4%, 61.8% and 57.7%, respectively. No significant correlation was observed between HO sensitivity and other variables, such as calendar period, tumor stage or site, or patient age or sex. HO sensitivity as estimated in the present experience is consistent with other reports of population-based screenings. Screening every year would achieve too limited an increase in sensitivity, compared to biennal screening, to be worth the difficulties of doubling organizational efforts and costs.

The existing guidelines recommend arteriovenous fistulae (AVF) surveillance by access blood flow (Qa) measurement and the correction of hemodynamically significant stenoses to prolong access survival. Unfortunately, many studies supporting these recommendations are inadequate methodologically; therefore, both the optimal criteria for surveillance and the value of preventive stenosis repair in AVF remain controversial. Recent literature confirms that Qa measurement allows an accurate identification of both stenosis (area under the curve (AUC) ranging from 0.80–0.93) and access at risk of failure (AUC ranging from 0.82–0.98) in AVFs and suggests a Qa <700–1000 ml/min and/or a reduction in Qa >25% as optimal predictors for stenosis and a Qa <400 ml/min for incipient thrombosis. Recent prospective studies evaluated whether Qa surveillance could improve AVF patency rates compared to monitoring based on clinical and dialysis-related criteria alone. The majority of studies have historical, rather than concurrent, control groups and provide conflicting results, some showing a reduction and some showing no change in thrombosis rates by Qa monitoring. On the other hand, the few randomized controlled studies available show that Qa surveillance, when coupled with preemptive intervention, reduces the already low thrombosis rate in AVF and suggest that the functional access life can be prolonged. However, there is still the need for additional methodologically adequate studies to understand fully the role of surveillance in AVF management.

Abstract
BACKGROUND Studies suggest that the ingestion of fish oil (FO), a source of the omega-3 polyunsaturated fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), can reduce the deleterious side-effects of chemotherapy. The aim of this randomised clinical trial was to evaluate the effect of supplementation with oral FO for 9 weeks on nutritional parameters and inflammatory nutritional risk in patients with haematological malignancies during the beginning of chemotherapy. METHODS Twenty-two patients with leukaemia or lymphoma were randomised to the unsupplemented group (UG) (n = 13) or supplemented group (SG) (n = 9). SG received 2 g/day of fish oil for 9 weeks. Nutritional status, serum acute-phase proteins and plasma fatty acids were evaluated before (T0) and after (T1) the intervention period. Data were analysed using two models; model 1, comprising data from all patients included in the study, and model 2, comprising data from UG patients with no increase in the proportions of EPA and DHA in plasma and data from SG patients showing an at least 100% increase in plasma EPA and DHA. RESULTS SG showed an increased plasma proportion of EPA and DHA in both models. In model 2, C-reactive protein (CRP) and CRP/albumin ratio showed larger reductions in the SG. Overall long-term survival in both models (465 days after the start of the chemotherapy) was higher in the group ingesting fish oil (P < 0.05). CONCLUSIONS These findings indicate an improved nutritional-inflammatory risk and potential effects on long-term survival in patients with haematological malignancies supplemented with FO during the beginning of chemotherapy.

Abstract
Immune system cell subsets in lymph nodes and spleen from alpine chamois (Rupicapra rupicapra subspecies rupicapra) living in the Italian Alps were characterized immunohistochemically. Seven primary antibodies (against human CD3, CD79αcy, CD68, or ovine CD4, CD8, CD21 and γδ T-cell receptor [TCR] epitopes) were tested on tissues fixed either in formalin or in zinc salts (ZS) and cross-reactivity with chamois immune cell epitopes was shown. ZS fixation allowed wider identification of immune cells, without the need for antigen retrieval. CD4(+) and CD21(+) cells were labelled only in ZS-fixed tissues. Reagents specific for human CD3, CD79 and CD68 antigens successfully detected chamois immune cells, both in ZS-fixed and formalin-fixed tissues. The reactivity and distribution of immune cells in lymph nodes and spleen were similar to those described in other domestic and wild ruminants. Results from this study may allow future investigation of the immune response and pathogenesis of diseases in the chamois.

Abstract
Inflammation is widely recognized as contributing to the pathology of acute and chronic neurodegenerative conditions. Microglial cells are pathologic sensors in the brain and activated microglia have been viewed as detrimental. Leukotriene, including cysteinyl leukotrienes (CysLTs) are suggested to be involved in brain inflammation and neurological diseases and ATP, by its receptors is a candidate for microglia activation. A23187 (10μM) stimulated microglia to co-release CysLTs and [3H]adenine based purines ([3H]ABPs), mainly ATP. The biosynthetic production of CysLTs was abolished by 10μM MK-886, an inhibitor of 5-lipoxygenase-activating protein activity. RT-PCR analysis showed that microglia expressed both CysLT1 / CysLT2 receptors, P2Y1 ATP-receptors and several members of the ATP binding cassette (ABC) transporters including MRP1, MRP4 and Pgp. The increase in [Ca2+]i elicited by LTD4 (0.1 μM) and 2MeSATP (100μM), agonists for CysLT- and P2Y1-receptors, was abolished by the respective antagonists, BAYu9773 (0.5 μM) and suramin (50 μM). The stimulation of both receptor subtypes, induced a concomitant increase in the release of both [3H]ABPs and CysLTs that was blocked by the antagonists and significantly reduced by a cocktail of ABC transporter inhibitors, BAPTA/AM (intracellular Ca2+ chelator) and staurosporine (0.1 μM, PKC blocker). P2Y antagonist was unable to antagonise the effects of LTD4 and BAYu9773 did not reduce the effects of 2MeSATP. These data suggest that: i) the efflux of purines and cysteinyl-leukotrienes is specifically and independently controlled by the two receptor types, ii) calcium, PKC and the ABC transporter system can reasonably be considered common mechanisms underlying the release of ABPs and CysLTs from microglia. The blockade of P2Y1 or CysLT1/CysLT2 receptors by specific antagonists that abolished the raise in [Ca2+]i and drastically reduced the concomitant efflux of both compounds, as well as the effects of BAPTA and staurosporine support this hypothesis. In conclusion, the data of the present study suggest a cross talk between the purine and leukotriene systems in a possible autocrine/paracrine control of the microglia-mediated initiation and progression of an inflammatory response.

Abstract
Fifty red foxes (Vulpes vulpes) from the district of Pisa (central Italy) were examined for ectoparasites. Sarcoptic mange was diagnosed on the presence of clearly visible skin lesions with confirmatory demonstration of Sarcoptes scabiei at parasitological and histopathological analysis. Ticks and fleas were collected directly from the carcases during post mortem examination, fixed and identified by morphological examination. For the detection of ear Malassezia and mite infections, cytological and parasitological examinations of ear wax samples were performed. All data were statistically analysed using a χ2 test with the Yates correction. An overall prevalence of 84% for ectoparasitic infections was found in examined subjects. In regard to isolated ectoparasites, 38%, 8%, 82%, 6% and 8% of foxes resulted positive for S. scabiei, Otodectes cynotis, Malassezia spp., fleas (Archaeopsylla erinacei, Pulex irritans, Ctenocephalides canis) and ticks (Ixodes ricinus and Rhipicephalus sanguineus), respectively. Malassezia ear infection was significantly more prevalent in animals older than 1 year (P < 0.01). Prevalence (38%), severity of lesions and poor body conditions observed in most Sarcoptes-infected animals indicate that sarcoptic mange should be considered the most important ectoparasitic infection of red foxes in the examined area. An overall prevalence of 84% for ectoparasitic infections was found in 50 Italian red foxes. Red foxes were infected by ticks, mites, fleas and Malassezia yeasts. Auricular infection with Malassezia was significantly more prevalent in animals older than 1 year. Malassezia was almost constantly associated with the presence of Sarcoptes mites and skin lesions. Based on prevalence, lesions and body condition, sarcoptic mange was the most relevant disease.

Abstract
Overexpression of cyclo-oxygenase (COX)-2 is involved in tumour growth and spread by modulating the production of angiogenic factors such as vascular endothelial growth factor (VEGF). Expression of COX-2 and VEGF was investigated immunohistochemically in 51 canine and feline cutaneous and non-cutaneous squamous cell carcinomas (SCCs) and the correlation between expression of these molecules and clinicopathological variables was evaluated. COX-2 and VEGF expression was not observed in normal skin keratinocytes. COX-2 overexpression occurred in 53% and 61% of the canine and feline SCCs, respectively. The expression of both markers was higher in cutaneous compared with non-cutaneous SCCs. In both species COX-2 and VEGF expression was correlated with the progression of the disease, but not with the presence of lymphatic invasion, tumour grading or tumour classification in the cutaneous tumours. Further study will be required to understand the role of the COX-2 pathway in angiogenesis in SCC.

Abstract
Electrochemotherapy combined with peritumoral interleukin-12 (IL-12) gene electrotransfer was used for treatment of mast cell tumours in 18 client-owned dogs. Local tumour control, recurrence rate, as well as safety of combined therapy were evaluated. One month after the therapy, no side effects were recorded and good local tumour control was observed with high complete responses rate which even increased during the observation period to 72%. IL-12 gene electrotransfer resulted in 78% of patients with detectable serum IFN-γ and/or IL-12 levels. In the treated tumours vascular changes as well as minimal T-lymphocytes infiltration was observed. After 1 week, the plasmid DNA was not detected intra- or peritumorally and no horizontal gene transfer was observed. In summary, our study demonstrates high antitumour efficacy of electrochemotherapy combined with IL-12 electrotransfer, which also prevented recurrences or distant metastases, as well as its safety and feasibility in treatment of canine mast cell tumours.

Abstract
BACKGROUND AND AIMS The positive and negative health effects of dietary carbohydrates are of interest to both researchers and consumers. METHODS International experts on carbohydrate research held a scientific summit in Stresa, Italy, in June 2013 to discuss controversies surrounding the utility of the glycemic index (GI), glycemic load (GL) and glycemic response (GR). RESULTS The outcome was a scientific consensus statement which recognized the importance of postprandial glycemia in overall health, and the GI as a valid and reproducible method of classifying carbohydrate foods for this purpose. There was consensus that diets low in GI and GL were relevant to the prevention and management of diabetes and coronary heart disease, and probably obesity. Moderate to weak associations were observed for selected cancers. The group affirmed that diets low in GI and GL should always be considered in the context of diets otherwise understood as healthy, complementing additional ways of characterizing carbohydrate foods, such as fiber and whole grain content. Diets of low GI and GL were considered particularly important in individuals with insulin resistance. CONCLUSIONS Given the high prevalence of diabetes and pre-diabetes worldwide and the consistency of the scientific evidence reviewed, the expert panel confirmed an urgent need to communicate information on GI and GL to the general public and health professionals, through channels such as national dietary guidelines, food composition tables and food labels.

Abstract
The aim of this study was to further investigate the role of wild boar (Sus scrofa) as a reservoir for hepatitis E virus (HEV). Sixty-four blood and faecal samples collected from wild boar hunted in Central Italy in 2011–2012 were examined by indirect enzyme-linked immunosorbent assay and RT-PCR analysis. Positive RT-PCR samples were further examined by nucleotide sequence determination and subsequent phylogenetic analysis. Thirty-six sera (56.2%) were positive for HEV-specific antibodies, and six (9.4%) faecal samples scored RT-PCR-positive results. Four animals were positive by both enzyme-linked immunosorbent assay and RT-PCR. Phylogenetic analysis showed that the detected wild boar–derived HEV sequences clustered within genotype 3, with similarity to sequences of human origin collected in a nearby area in 2012. Our data confirm that HEV is endemic in the wild boar population in the research area and that these wild animals could play an important role in the epidemiology of HEV infection.

Abstract
In this work we investigated the ability of four extremophilic bacteria from Archaea and Bacteria domains to resist to space environment by exposing them to extreme conditions of temperature, UV radiation, desiccation coupled to low pressure generated in a Mars’ conditions simulator. All the investigated extremophilic strains (namely Sulfolobus solfataricus, Haloterrigena hispanica, Thermotoga neapolitana and Geobacillus thermantarcticus) showed a good resistance to the simulation of the temperature variation in the space; on the other hand irradiation with UV at 254 nm affected only slightly the growth of H. hispanica, G. thermantarcticus and S. solfataricus; finally exposition to Mars simulated condition showed that H. hispanica and G. thermantarcticus were resistant to desiccation and low pressure.

Abstract
In this single-centre, retrospective study, we analyzed data of 194 patients receiving antiretroviral therapy with <50 human immunodeficiency virus (HIV) RNA copies/mL in plasma and 318 HIV RNA/DNA paired samples. By kinetic polymerase chain reaction (kPCR) molecular system analysis, 104 (54%) subjects had undetectable HIV RNA and 90 (46%) had residual viraemia. Median (interquartile range) HIV DNA load was 780 (380-1930) copies/10(6) peripheral blood lymphocytes (PBL), and HIV DNA loads were independently associated with residual viraemia (p 0.002). Virological rebound occurred in 29/194 (15%) patients over a median (interquartile range) follow-up of 17.5 (13.5-31.5) months. Residual viraemia (p 0.002), but not HIV DNA load, was independently associated with virological rebound.
