Introduction
Infective endocarditis (IE) is a severe disease associated with high morbidity and mortality. The EURO-ENDO registry reported a mean age of 59.25 ± 18.03 years; 46.3% of patients were over 65 and 12.0% over 80 years. Little is known about the best management of elderly patients with IE. In these patients, surgery may be challenging.
Purpose
We aimed to determine the clinical and echographic characteristics, the therapeutic strategy, and the outcome of IE in octogenarians.
Method
We retrospectively included in the analysis 457 consecutive patients with definite active IE in a single surgical centre. Descriptive statistics are reported as mean ± standard deviation (SD) or median ± interquartile range (IQR) for continuous variables with normal and non-normal distribution and as frequencies and percentages for categorical variables. Between-groups comparisons were assessed by Student’s t-test, Mann-Whitney U test, Kruskal-Wallis, or chi-square test, as appropriate. Univariate long-term survival was analysed by the Kaplan-Meier method.
Results
In our cohort, octogenarians were 17% of the whole population (N = 77). In patients under the age of eighty, males were mostly involved with a sex ratio exceeding 2:1. This ratio was inverted in older people, where the female gender represented 57% of the total (0.001). Staphylococcus aureus (10.4 vs 20.5%, p =0.038) and Enterococci (29.9 vs 16.3%, p =0.008) were significantly less and more frequent than in younger people, respectively. Comorbidities were more frequent in elderly patients, such as hypertension (80.5 vs 53.2%, p = 0.001), dyslipidaemia (42.7 vs 27.3%, p = 0.008), and history of cancer (29.9 vs 19.2%, p = 0.036). Consequently, EUROSCORE II was higher (median ± IQR 19.18 ± 19.0 vs 11.9 ± 5.7, p = 0.001). In octogenarians, IE was more frequently left-sided (98.7 vs 89.2, p = 0.009) and complicated less often with peripheral embolism (31.2 vs 43.9%, p = 0.038). We found no differences between the two groups for the type of infected valve (native or prosthetic), the severity of valve dysfunction, paravalvular extension, and vegetation length. Octogenarians were more often excluded from surgery despite indication (19.5 vs 7.7%, p = 0.016) and had higher thirty-day (11.7 vs 7.9%, p = 0.001) and three-year (45 vs 30%, p = 0.001) mortality than younger patients.
Conclusions
Octogenarians represent a considerable proportion of overall cases of IE, with specific clinical and microbiological characteristics. Older patients are more often excluded from surgery, and the overall prognosis is poor. Abstract Figure.

Background
Anorexia Nervosa (AN) is a psychiatric disorder that can lead to cardiac complications, especially in severely malnourished patients. Cardiovascular involvement includes autonomic dysfunction (increased vagal tone, bradycardia, orthostatic hypotension, syncope), arrhythmias, pericardial effusion, heart failure and sudden death. A few studies have examined the echocardiographic abnormalities secondary to AN, reporting mainly a decreased cardiac mass and an increased incidence of pericardial effusion. No previous studies examined the changes of Global Longitudinal Strain (GLS), which has been shown to be an early marker of myocardial damage in other subsets.
Purpose
This study aimed to characterize echocardiographic abnormalities in AN, and to assess impairment of global and regional longitudinal strain (LS) and its clinical value in this context.
Methods
We prospectively enrolled 42 consecutive patients (1 male) admitted to a highly specialized AN unit between November 2020 and July 2021 with AN (Mental Disorders, 4th Edition-DSM IVr). We also selected 34 healthy controls, matched for age and sex. In all subjects, we reported the cardiac frequency, systolic and diastolic blood pressure, blood examinations, and we performed an echocardiography, including GLS measurement. Eighteen patients were treated with enteral or parenteral feeding. A subset of 26 AN patients performed a second echocardiography after one month of follow up; 14 of them received forced feeding.
Results
Compared with healthy subjects, AN patients had significantly lower albumin levels (45.1 ± 10.3 vs 66.0 ± 4.8 mg/dl, p = 0.031), lower FT3 levels (3.7 ± 1.0 vs 7.9 ± 6.4 pg/mL, p = 0.001), higher FT4 levels (13.8 ± 1.8 vs 9.6 ± 8.1 pg/mL, p = 0.008), a lower cardiac frequency (63 ± 18 vs 73 ± 12 bpm, p = 0.004), a higher incidence of pericardial effusion (9/42 vs 0/34, p = 0.008), a lower myocardial mass (62.3 ± 15.0 vs 98.5 ± 28.5 g, p < 0.001), a lower absolute value of GLS (-18.8 ± 2.8 vs -20.3 ± 2.0 %, p = 0.014) and basal LS (-15.4 ± 6.1 vs -19.6 ± 2.8 %, p < 0.001). The bull’s eye mapping showed a plot pattern with blue basal areas in 17/42 AN patients vs 1/34 healthy subjects (p < 0.001). The 17 anorexic patients with a blue basal pattern needed forced feeding in a higher proportion (11/17 vs 7/25, p = 0.018) and presented more frequently amenorrhea (14/17 vs 11/25, p = 0.046). During the follow up (26 AN patients performed a second echocardiography), of 13 patients with blue areas in the first bull’s eye mapping, 11 recovered a completely red pattern, and of 13 patients with a red bull’s eye in the first examination, no one presented blue areas on the second one.
Conclusions
GLS is significantly altered in AN patients and a basal blue pattern on bull’s eye mapping individuates more severe cases. These changes seem to be reversible (Figure 1), although further studies are necessary to understand which factors influence this pattern besides BMI. Abstract Figure 1

Abstract
Abstract
Introduction
Injection drug use (IDU) is a known risk factor for infective endocarditis (IE) and is associated with frequent recurrences, but its prognostic impact is still debated. Moreover, the potential futility of surgery in this population is an unsolved matter.
Purpose
We aimed to determine the clinical characteristics, the therapeutic strategy, and the prognostic impact of injection drug use IE (IDUIE).
Method
We retrospectively included in the analysis 454 consecutive episodes of definite active IE admitted in a single surgical centre from January 2012 to December 2020; 14 out of them where a subsequent infective episode of the same patient.
Results
IDUIE cases were 63 (13.8%), without significant proportional differences over time. IDUIE patients were significantly younger (43.95±10.12 vs 67.84±13.33, p 0.00) and presented fewer comorbidities (p<0.001). They were admitted with a first episode of IE only in 60.3% of cases vs 92.8% of non-IDU (p<0.001). Embolism was present at admission in a higher percentage (60.3 vs 38.4%, p<0.001). IDUIE was more frequently associated with spondylodiscitis (15.9 vs 7.4%, p=0.026). The infection was less frequently left-sided than in non-IDU patients (57.1 vs 97.2%, p<0.001) and was more often polimicrobic (12.7 vs 4.9%, p=0.015). Most patients were positive for Staphylococcus aureus (54.0 vs 12.8%, p<0.001), while Streptococci were significantly less frequent in patients with IDUIE (11 vs 25%, p=0.015). The proportion of patients undergoing surgery was similar among the two groups (85.5 vs 78.8%, NS). IDUIE patients treated medically for absence of surgical indication had a better survival than patients undergoing surgery for complicated IE (p<0.001). IDUIE was associated with a higher proportion of relapse during follow-up (28.3 vs 3.3%, p<0.001). It was not associated with higher mortality (Figure 1) but was an independent predictor of mortality in multivariable analysis including age (HR per unit 1.048, 95% CI 1.038–1.063, p=0.00) and drug abuse (HR 3.2, 95% CI 1.8–5.6, p=0.00; Figure 2). Among IDUIE patients, we did not find predictors of futility of surgery, not even multiple relapses.
Conclusions
IDUIE represents a considerable proportion of overall cases of IE, mainly affecting young people. Staphylococcus aureus is the most common microbiologic agent. IDUIE is not associated with higher mortality but drug abuse is an independent predictor of mortality. Considering that patient with uncomplicated IE treated medically have a better prognosis, we should reserve surgery to patients with a strict indication for it. On the other hand, since there are no predictors of futility of surgery, all patients with a complicated IE should undergo surgery without delay. The main determinant of prognosis in these patients is not IE but drug abuse itself. For this reason, increased focus on addiction treatment following hospital discharge is mandatory to improve long term prognosis.

Abstract
Abstract
Introduction
Most cases of infective endocarditis (IE) involve a single valve, and little is known concerning IE that simultaneously affects two valves. The involvement of more than one valve may imply more severe and extensive cardiac lesions. In these patients, surgery may be challenging.
Purpose
We aimed to determine the clinical characteristics, the therapeutic strategy, and the prognostic impact of double-valve IE (DVIE).
Method
We retrospectively included in the analysis 380 consecutive patients with definite active IE in a single surgical centre. The univariate and multivariate long-term survival was analysed by the Kaplan-Meier method and by stepwise Cox proportional hazards models, respectively. We repeated the mortality analysis using the propensity score matching technique, to adjust for baseline differences between SVIE and DVIE groups.
Results
DVIE occurred in 60 of the total enrolled 380 patients (15.8%) and involved mostly the combination of mitral and aortic valves (N=52, 87%). Most patients had double-native IE (N=38, 63%). Staphylococci were significantly less frequent in patients with double-valve than single-valve IE (SVIE). The proportion of patients undergoing valve repair among those treated surgically was higher for patients with DVIE than for SVIE (p<0.001). Valve repair of at least one valve was associated with non-significant better survival than double replacement. DVIE was associated with higher all-cause mortality than SVIE (p<0.001). DVIE was not associated with a higher risk of relapse or non-fatal adverse events.
Conclusions
DVIE represents a considerable proportion of overall cases of IE, mainly involving aortic and mitral valves, with a jet lesion on the mitral valve; Staphylococcus is significantly less frequent than in SVIE; DVIE is independently associated with higher mortality; finally, mitral valve repair is feasible in a considerable proportion of surgical cases.

Abstract
Potentially toxic elements are widespread soil contaminants, whose occurrence could entail a concern for human health upon ingestion of fruit and vegetables harvested in a polluted area. This work set out to evaluate the concentrations of lead and cadmium as well as the levels of thirteen heavy metals for which a limit value is yet to be established by the food safety authorities, in order to perform a risk characterization related to the dietary intake of these metals and to provide a scientific opinion with wider relevance in the light of current worldwide regulatory issues. The sampling consisted of fruit and vegetables grown in a potentially contaminated area of southern Italy due to the illegal dump of hazardous wastes. An evaluation of the dietary exposure through the calculation of the Hazard Index (HI), the Maximum Cumulative Ratio (MCR) and the Target Cancer Risk (TCR) was adopted to this end. The results revealed that about the 30% of samples showed quantifiable levels of chemicals and no significant difference emerged between the potentially polluted area and the nearby cities that were selected as a control landfill site. The overall risk characterization for non-carcinogenic endpoints showed that the HI did not reach unsafe values, except for a small number of samples mainly because of aberrant occurrences and, in any case, the cumulative toxicity was mainly driven by thallium and vanadium. As far as the carcinogenic effects of arsenic are concerned, the distribution of TCR values broadly lay below the safety threshold; a certain percentage of data, however, exceeded this limit and should be taken into account for the enforcement of future regulatory thresholds.

Abstract
The mPEBev is an anticancer regimen which combines a chemotherapy doublet, based on cisplatin and oral etoposide (mPE), with bevacizumab (mPEBev), a mAb targeting the vasculo-endothelial growth factor (VEGF). In previous studies, this regimen showed powerful anti-angiogenetic effects and significant antitumor activity in metastatic non-small-cell lung cancer (mNSCLC) patients. We also recorded the best benefit in patients exhibiting low-systemic inflammatory profile at baseline. On these bases, we hypothesized that mPEBev antitumor activity could be partially related to bevacizumab-associated immunological effects. For this reason, we performed an immunological monitoring in 59 out of 120 stage IIIb-IV NSCLC patients enrolled in the BEVA2007 phase II trial, who received fractioned cisplatin (30 mg/sqm days 1-3q21) and oral etoposide (50 mg, days 1-15q21) (mPE doublet) ±bevacizumab. In this group of patients, 12 received the mPE doublet alone and 47 the doublet in combination with bevacizumab (5 mg/kg on the day 3q21; mPEBev regimen). Blood cell counts, serum analysis, multiplex cytokine assay and immunocytofluorimetric analysis, performed on baseline and post-treatment on blood samples from these patients, revealed that bevacizumab addition to the doublet decreased levels of pro-angiogenic (VEGF, Angiostatin-1 and Follistatin) and inflammatory cytokines (interferon (IFN)γ, IL4 and IL17), improved in vivo and in vitro cytotoxic T-lymphocytes (CTL) response and promoted dendritic cell activation. These results suggest that the mPEBev regimen improve the micro-environmental conditions for an efficient antigen-specific CTL response, making it a feasible candidate regimen to be assessed in combination with immune-checkpoint inhibitors in NSCLC patients.

Abstract
INTRODUCTION In Italy, the current legislation for contaminants in soils provides two land uses: residential/public or private gardens and commercial/industrial; there are not specific reference values for agricultural soils, even if a special decree has been developed and is currently going through the legislative approval process. The topic of agricultural areas is relevant, also in consideration of their presence near potentially contaminated sites. Aim and results. In this paper, contamination sources and transport modes of contaminants from sources to the target in agricultural areas are examined and a suitable "conceptual model" to define appropriate characterization methods and risk assessment procedures is proposed. These procedures have already been used by the National Institute of Health in various Italian areas characterized by different agricultural settings. CONCLUSION Finally, specific remediation techniques are suggested to preserve soil resources and, if possible, its particular land use.

Abstract
As certified by the World Health Organization (WHO), exposure assessment represents a key stage in epidemiological studies that aim to evaluate health risks linked to contaminated sites. The assessment procedure is contingent on the availability of data relating to environmental and food compartments and on any other available scientific evidence, such as data on toxicity and human biomonitoring. This chapter outlines the procedure that should be adopted in order to conduct an accurate exposure assessment and presents three case studies involving different types of contaminated sites where this approach was applied.

Abstract
BACKGROUND Social Anxiety Disorder (SAD) is one of the most prevalent anxiety disorders in Europe and comprises the fear of public speaking as its typical sub-type. Cognitive-Behavioural Therapy (CBT) is the intervention of choice for SAD, and it includes exposure to anxiety-provoking stimuli to induce systematic desensitization and reduce anxiety. Similarly, exposure therapy per se has been used and found effective, although it is not as specific as CBT for the treatment of SAD. Interestingly, exposure to anxiety-provoking situations can be achieved in Virtual Environments (VEs) through the simulation of social situations allowing individuals with public speaking anxiety to live and develop real exposure-like reactions. The Virtual Reality Exposure Therapy (VRET) is the treatment of anxiety disorders based on such VEs. AIM This article aims to provide an overview of the scientific literature related to the applications of Virtual Reality to the treatment of fear of public speaking. MATERIALS AND METHODS We conducted the literature review on PubMed and Google Scholar for studies including the fear-of-public-speaking VEs. RESULTS AND CONCLUSIONS Reviewed studies addressed two main aspects: the design parameters of the VEs for adequate reactions to synthetic social stimuli, and the efficacy of VEs for fear of public speaking treatment. VEs resulted effective for triggering as-if-real reactions in relation to public speaking. VE-based exposures reduced public speaking anxiety measurements, decreased scores and maintained them at 3 month follow-up. Studies comparing VRET to pharmacological therapy are lacking, and there are few randomized controlled trials that compare VRET to CBT, especially on fear of public speaking treatment.

Abstract
At the moment, the health-environmental risk analysis is used to decision-making targets in the contaminated sites management; this procedure allows to assess the quantitative health risk related to the pollutants presence in environmental compartments, as soil and waters. As regards potentially contaminated agricultural soils, the ingestion of food from vegetable and/or animal source, produced inside the contaminated area, is the most suitable way to assess the health risk. As an official procedure to this assessment is not available, the National Institute for Health (Istituto Superiore di Sanità, ISS) has worked out an operating procedure, organized into several phases, depending on the available specific-site know-how. In this document, agricultural soils potentially contaminated in two sites have been studied; the sites are the following: Brescia Caffaro and Torviscosa.

Abstract
The development of an analytical method for the determination of four selected pyrethroid insecticides at residue level in beef meat is presented. Acetone and petroleum ether at 40-60 degrees C were chosen as extraction solvents. A two-step clean-up was performed using an Extrelut NT3-C(18) system followed by a Florisil column, with disposable, ready-to-use cartridges. Instrumental analysis was carried out on a gas chromatograph equipped with an electron capture detector (GC-ECD), using matrix-matched and internal standard calibration techniques. Confirmatory analysis by GC-MS was performed. Recoveries at the EU Maximum Residue Limit (MRL), 0.5 x MRL and 1.5 x MRL levels and the repeatabilities were widely satisfactory. The main advantage of the method was the reduction of analysis time as compared with previously published works. The applicability of the method to different matrices and pesticide classes will be investigated.

Abstract
An analytical method for the routine simultaneous determination of four nicotinoid insecticides (acetamiprid, imidacloprid, thiacloprid and thiamethoxam) in commercial multifloral honey was developed. Fortified honey samples, dissolved in water, were cleaned up through Extrelut NT20 column and, finally, insecticides were eluted with dichloromethane. The eluate was evaporated, the residue redissolved in methanol and then analyzed by LC-ESI(+)-MS. Average recoveries of the four analytes were in the range of 76% and 99% at both spiking levels 0.1 and 1.0 mg kg(-1). Relative standard deviations (RSDs) were less than 10% for all of the recovery tests. The detection limits (LODs) of the method ranged from 0.01 to 0.1 mg kg(-1) for the different insecticides studied. The developed method is linear over the range assayed, 0.5-5.0 microg mL(-1), with linear correlation coefficients higher than 0.9993.

Abstract
Edible portions of 12 marine organisms from several areas of the Adriatic Sea, Italy, were collected during Spring 1997 and analysed for 32 organochlorine pesticides residues and 27 polychlorobiphenyl congeners. Only eight organochlorine pesticides - hexachlorobenzene (HCB), hexachlorocyclohexane (HCH) isomers, diphenyl-dichloro-trichloroethane (DDT) group, dieldrin - were determined at levels in the range <0.01-19.88 ng g(-1) wet weight, with 1,1'-dichloro-2,2'-bis(4-chlorophenyl)ethylene (DDE) being the more relevant single organochlorine. The contamination by organochlorine pesticides was comparable in organisms from the North, Centre and South Adriatic. Polychlorinated biphenyls (PCBs) were determined at levels in the range <0.05-14.46 ng g(-1), with CB 101, 118, 138, 153, 180 and 187 being more relevant (penta-, hexa- and hepta-chlorinated congeners). The sum of PCBs congeners determined were in the range 1.18-69.05 ng g(-1). The contamination by PCBs is more relevant in organisms from the North Adriatic Sea owing to the antropic discharge from major rivers such as Po and Adige that flow through highly industrialized and densely populated areas.
