Abstract
PURPOSE To evaluate the variables influencing the therapeutic choice toward oral versus subcutaneous semaglutide in a cohort of diabetic subjects. METHODS We retrospectively collected data of 292 patients followed at the Diabetes Unit of the University Hospital of Siena and the Hospital of Grosseto, who were prescribed oral (n = 115) or subcutaneous (n = 177) semaglutide between October 2021 and October 2022. RESULTS Oral semaglutide was preferentially prescribed in older subjects with longer disease duration in replacement of other antidiabetic drugs, while subcutaneous semaglutide was preferentially prescribed in add-on to metformin in subjects with higher body weight and BMI. After 6 months, both formulations significantly improved glycemic control and body weight, however injectable semaglutide showed a greater efficacy on A1c levels, weight loss, BMI and waist circumference reduction. No differences were found in terms of adverse events. CONCLUSION In our experience, injectable semaglutide is preferred in patients with excess weight and shorter disease duration, while the oral formulation was used later and especially after therapeutic failure of previous therapies. Follow-up data indicate similar tolerability and efficacy of both formulations, despite subcutaneous semaglutide demonstrated greater efficacy.

Abstract
Solar driven advanced oxidation processes (AOPs) (an alternative solar photo Fenton like process (SPF), sunlight/H2O2 (SHP) and sunlight/chlorine (SCL)) and respective dark conditions, were compared for the first time to conventional (chlorination and UV-C radiation) disinfection processes, in the inactivation of E. coli and Entero strains inoculated in real roof-harvested rainwater (RHRW), to evaluate their possible safe use for crop irrigation. In this regard, bacterial regrowth was also evaluated 6, 12, 24 and 48 h after disinfection treatment. The SPF, using iminodisuccinic acid (IDS)-Cu complex as catalyst, was optimized (H2O2/IDS-Cu 55/1 best molar ratio) under mild conditions (spontaneous pH) and sunlight. The faster inactivation kinetics were observed for the SCL process (k = 1.473 min-1, t1/2 = 0.47 min for E. coli and k = 1.193 min-1, t1/2 = 0.57 min for Entero), while the most effective processes in controlling bacterial regrowth were SPF and SCL. Although UV-C radiation (0-1.3 × 104 μW s cm-2 dose range) was the second faster disinfection process (k = 1.242 min-1, t1/2 = 0.55 min for E. coli and k = 1.150 min-1, t1/2 = 0.60 min for Entero), it was the less effective process in controlling bacterial regrowth (>10 CFU 100 mL-1 already after 6 h post-treatment incubation). According to the bacterial inactivation and regrowth tests carried out in this work, SPF and SCL are interesting options for RHRW disinfection, in case of effluent use for crop irrigation.

Abstract
Right ventricular failure (RVF) after left ventricular assist device (LVAD) implant is associated with increasing morbidity and mortality. The aim of this study was to identify the best predictors of RVF post LVAD-implant among biochemical, haemodynamic and echocardiographic parameters. From 2009 to 2019, 38 patients who underwent LVAD implantation at our centre were prospectively enrolled. Preoperative clinical, laboratory, echocardiographic and haemodynamic parameters were reported. Overall, eight patients (21%) developed RVF over time, which revealed to be strongly related to overall mortality. Pulmonary artery pulsatility index (PAPi) resulted to be the most significant right heart catheterization index in discriminating RVF vs no RVF patients [(1.32 ± 0.26 vs. 3.95 ± 3.39 respectively) p = 0.0036]. Regarding transthoracic echocardiography, RVF was associated with reduced free wall right ventricular longitudinal strain (fw-RVLS) (- 7.9 ± 1.29 vs. - 16.14 ± 5.83) (p < 0.009), which was superior to other echocardiographic determinants of RVF. Among laboratory values, N-terminal pro-brain natriuretic peptide (NT-proBNP) was strongly increased in RVF patients [(10,496.13 pg/ml ± 5272.96 pg/ml vs. 2865, 5 pg/ml ± 2595.61 pg/ml) p = 0.006]. PAPi, NT-proBNP and fwRVLS were the best pre-operative predictors of RVF, a post-LVAD implant complication which was confirmed to have a great impact on survival. In particular, fwRVLS has been proven to be the strongest independent predictor.

Abstract
PURPOSE OF REVIEW This review attempts to summarize the role of standard and advanced echocardiographic techniques together with CMR in the evaluation of the RV in HF, providing an outlook on the recent evidence. RECENT FINDINGS In the last decade, there has been growing interest in the study of the RV, and it is now widely established that RV function is a strong predictor of mortality, in several cardiovascular diseases, in particular in the setting of heart failure (HF). The evaluation of RV function might be particularly challenging, which justifies the necessity of multi-modality imaging. The echocardiographic assessment remains the mainstay technique even though it might be complex, due to RV crescent shape and its position in the chest, requiring both qualitative and quantitative parameters. Cardiac magnetic resonance (CMR) represents a complementary exam which is particularly useful when precise structural and functional assessment are needed, considering the most recently developed sequences. Despite the technological improvement attested over the last years, there is still no universally accepted parameter that univocally defines RV function, hence the necessity to evaluate several parameters, combining different imaging techniques.

Abstract
Abstract
Background
Cardiovascular disease (CVD) is the leading cause of mortality in western countries and the first cause of mortality in women.
Purpose
Women generally do not concern about CVD and that represents the main risk for them.
Methods
Misericordia Hospital, Grosseto, started a Clinic of Health and Gender Medicine on 2017. On the first and third Monday of every month, we evaluate < 60 years patients who are at risk for traditional CVD, depression, early menopause, polycystic ovary, autoimmune and rheumatic disease. On the first visit, medical history, arterial pressure, electrocardiogram, body mass index, waist circumference and lipid profile, were collected. We also supply questionnaires to evaluate diabetes and depression risk by Generalized Anxiety Disorder (GAD-7), Patient Health Questionnaire (PHQ-9) and food diary. Two weeks later, a multidisciplinary team (cardiologist-diabetologist-nutritionist-gynecologist-psychiatrist and a nurse) evaluates the patients defining the personal risk profile.
Results
From 2017 to December 2019, 74 females and 7 males belonging to the target population were examined. Age group: <45(61%), 46-50(26%), 51-60(48%), >60(19%). Clinical characteristics: Hypertension: 64%; Obesity 5%; Unknown dyslipidemia 44%; Risk of diabetes: 39%; Gestational diabetes: 5%; Gestational hypertension: 5% CVD risk: 42%; Depression: 33% Autoimmune disease: 30%. From them 60.5% have needed further investigation. Follow-up is going on.
Conclusions
according with the literature, more than 50% of the cohort was unconsciously at high risk of CVD. So a multidisciplinary approach is needed in order to frame a complex health status. Thus we established collaboration with patients to improve lifestyles as CVD-prevention's tool.
Key messages
Cardiovascular disease represent often an hidden health problem, especially in women. Multidisciplinary approach is needed to face CVD.

Abstract
UNLABELLED Notwithstanding technological improvements in endovascular devices treatment of steno-obstructive lesions of the superficial femoral artery (SFA) remains a challenge for today's vascular surgeon. Current opinion dictates that the diabetic population may have worse outcome after revascularization of the lower extremities. Herein we examine the effects of endovascular treatment on steno-obstructive lesions of the SFA in diabetic and non-diabetic patients. METHODS A retrospective analysis was carried out on 110 patients who had undergone endovascular treatment of the SFA from 2010 to 2017 comparing outcomes in diabetic (DM) vs non-diabetic patients (nDM). RESULTS 56 (50.9%) of the patients were diabetic and 54 were non-diabetic (49.1%). 52.7% (62.7% DM vs 35.2% nDM, p = 0.0003) were patients with critical limb ischemia. SFA occlusion was present in 65.5% (60.7% DM vs 70.4% nDM, p = 0.29) of all patients. All had undergone PTA of the SFA and 40.9% had received adjunctive stenting (44.6% DM vs 37.0% nDM, p = 0.41). A multilevel treatment was executed in 39.1% (51.8% DM vs 25.9% nDM) of the cases whereas an infra-popliteal procedure was associated in 27.3% (37.5% DM vs 16.7% nDM). In both groups the presence of diabetes was significantly associated (p = 0.005 e p = 0.014, respectively). Reintervention rate was 22.7%; 13 in the diabetic group (23.2%) and 12 in the non-diabetic group (22.2%). Of those who had had reintervention (p = 0.77); 9 patients (8.2%) had undergone an open surgical operation, 6 of whom had diabetes (p = 0.32). 5 patients (4.5%) had had major amputation, 4 of whom were diabetic (p = 0.20). Curves assessing freedom from target lesion restenosis were substantially overlapping between the two groups. CONCLUSION No statistical associations between diabetes and reintervention or amputation rates were found. Indication to treat the SFA were not influenced by the presence of diabetes but further investigation is required to verify our hypothesis.

Abstract
Contaminants of emerging concern (including pharmaceuticals) are not effectively removed by municipal wastewater treatment plants (WWTPs), so particular concern is related to agricultural wastewater reuse due to their possible uptake in crops irrigated with WWTPs effluents. Advanced oxidation processes (AOPs) and solar AOPs have been demonstrated to effectively remove pharmaceuticals from different aqueous matrices. In this study, an heterogeneous photocatalytic process using powdered nitrogen-doped TiO2 immobilized on polystyrene spheres (sunlight/N-TiO2) was compared to the benchmark homogenous AOP sunlight/H2O2 in a compound triangular collector reactor, to evaluate the degradation of three pharmaceuticals (carbamazepine (CBZ), diclofenac (DCF), trimethoprim (TMP)) in water. The degradation of the contaminants by sunlight and sunlight-AOPs well fit the pseudo-first order kinetic model (but for TMP under sunlight). High removal efficiency by solar photolysis was observed for DCF (up to 100%, half-life sunlight cumulative energy QS,1/2 = 2 kJ L-1, half-life time t1/2 = 32 min), while CBZ (32%, QS,1/2 = 28 kJ L-1, t1/2 = 385 min) and TMP (5% removal after 300 min) removal was poor. The degradation rate of CBZ, TMP and DCF was found to be slower during sunlight/H2O2 (QS,1/2 = 5 kJ L-1, t1/2 = 77 min; QS,1/2 = 20 kJ L-1, t1/2 = 128 min; QS,1/2 = 4 kJ L-1, t1/2 = 27 min, respectively) compared to sunlight/N-TiO2 (QS,1/2 = 4 kJ L-1, t1/2 = 55 min; QS,1/2 = 3 kJ L-1, t1/2 = 42 min; QS,1/2 = 2 kJ L-1, t1/2 = 25 min, respectively). These results are promising in terms of solar technology upscale because the faster degradation kinetics observed for sunlight/N-TiO2 process would result in smaller treatment volume, thus possibly perspective compensating the cost of the photocatalyst.

Abstract
Abstract
Background
Prognosis of patients with acute heart failure (AHF) and different etiologies remains a challenging issue for the Cardiologist.
Purpose
We aimed to evaluate clinical and echocardiographic indexes and blood tests values of patients admitted to Intensive Care Unit (ICU) for AHF to test their capability to predict events at short-, medium- and long-term follow-up.
Methods
We retrospectively enrolled 830 patients who entered the ICU of our third-level hospital between 2010 and 2013 for AHF. Exclusion criteria included: active malignances, heart transplantation, patients with left ventricular assist device. We evaluated in each subject: cause of admission, medical history, chest congestion severity at admission, blood tests, echocardiographic parameters and administered drugs during in-hospital stay. Primary endpoints included: mortality rate at 30 days, 6 months and 5 years after dismission, days of ICU stay and cardiology ward stay. Indexes with statistical significance at univariate analysis, were then tested by multivariate analysis.
Results
The study population (average age 72.2±13 y) had an ejection fraction (EF) 36±12% at ICU admission. Best predictors of prognosis in the populations, after multivariate analysis, resulted to be: renal failure, EF, age, mitral regurgitation (MR) more than mild, use of non-invasive ventilation support during ICU stay, previous stroke or transient ischemic attack (TIA). With these indexes, we created a multi-parametric prognostic score composed by: 0.7*[age >76 years] + 1.4*[plasmatic creatinine >2mg/dl] + 0.8*[non-invasive mechanical ventilation] + 0.9*[previous stroke/TIA] + 0.8*[EF <30%] + + 0.7*[previous hospitalization for AHF] + 0.5*[moderate/severe MR]. According to the score, we stratified the population in 3 tertiles with increasing mortality risk: low if <1.5, medium if 1.5–3, high risk if >3 (Figure 1). At ROC curve analysis, the score showed a greater prognostic accuracy than each parameter (30 days AUC 0.75, 6 months AUC 0.78, 5 years AUC 0.79).
Figure 1
Conclusions
A combined clinical, humoral and echocardiographic score could represent a new tool in the prognostication of patients with AHF since the admission in ICU.

Abstract
La prescripción de la actividad física, el ejercicio y evitar las conductas sedentarias poseen un invalorable referente en el personal de salud. El objetivo de esta investigación fue estudiar el nivel de actividad física y sedentarismo en un grupo profesionales de la salud mediante el uso de acelerometría. También se indagó acerca del estado nutricional de los sujetos y su relación con los niveles de actividad física y sedentarismo. Los sujetos del presente estudio reportaron ser activos (76%) pero se registraron un promedio de 592 minutos de tiempo sedentario, indicando que la mayoría de las personas pasan más de 9 horas sentadas. Los profesionales estudiados si bien parecen ser activos, son extremadamente sedentarios. La indicación de ejercicio como terapéutica sería más creíble si los profesionales fuesen activos, realizaran ejercicio regularmente, y además evitaran prolongados tiempos de conducta sedentaria.

Abstract
Intrahepatic cholestasis of pregnancy (ICP) is a liver disorder characterized by maternal itching and altered liver function. Interleukin (IL)-31 is known to be involved in the pathogenesis of pruritic inflammatory skin diseases. In a three-year period, 13 women with a singleton pregnancy and a diagnosis of intrahepatic cholestasis (ICP) were enrolled together with 26 healthy single pregnant women who concluded an uncomplicated pregnancy. The inclusion criteria were itching and elevated levels of liver transaminases. Median serum levels of IL-31 were significantly higher in ICP patients than in the control group (p = 0.004). Furthermore, IL-31 values were directly dependent on liver transaminase levels.

Abstract
This study evaluated the usefulness of diffusion-weighted (DW) magnetic resonance imaging (MRI) and ADC maps in the differential diagnosis of brain abscesses from cystic or necrotic neoplasms. MR images of 49 patients with 54 lesions were examined retrospectively. All patients underwent conventional MRI and DWI, and ADC values were calculated by placing ROIs of 30 mm2 manually over the cystic part of the lesions. On DWI, all cystic portions of abscesses were hyperintense. Mean ADC values were 0.48×10 mm2/s (range 0.41–0.54×10 mm/s) for pyogenic abscesses, 0.73×10 mm2/s (range 0.65–0.91×10 mm/s) for mycotic abscesses and 0.6 mm2/s for Nocardia abscess. Cystic areas appeared hypointense on DWI in 33/44 tumours (mean value ADC 1.96 mm2/s). Eleven tumours (11/44) appeared hyperintense on DWI: eight metastases from lung cancer (mean ADC value 0.86 mm2/s, range 0.75–1.2 mm2/s), two GBMs (mean 0.7 mm2/s, range 0.67–0.76 mm2/s) and one anaplastic astrocytoma (ADC value 1.24 mm2/s). ADC values may help in differentiating pyogenic abscess from brain tumors or metastatic lesions.

Abstract
The effect of TiO₂ photocatalysis on the inactivation of an antibiotic resistant Escherichia coli strain selected from an urban wastewater treatment plant (UWWTP) effluent was investigated. Different light sources including a 250 W wide spectrum lamp, a 125 W UV-A lamp and solar radiation, as well as, photocatalysts loadings (TiO₂ Degussa P25) in the range from 0.05 to 2.00 g TiO₂ L(-1) were evaluated. The higher efficiency (total bacterial inactivation after 10 min of irradiation) was observed in the absence of TiO₂ when the wastewater was irradiated using the 250 W lamp. In the presence of TiO₂ a decreasing inactivation trend was observed (99.76% and 72.22% inactivation after 10 min irradiation at 0.10 and 2.00 g TiO₂ L(-1) respectively). Under solar simulated conditions the highest inactivation efficiency (93.17%) after 10 min of irradiation was achieved at the lower photocatalyst loading (0.05 g TiO₂ L(-1)). The concept of "reactor optical thickness" was introduced to explain the rates of disinfection observed. The optimum photocatalyst loading estimated by radiation absorption-scattering modeling was found to be 0.1 g TiO₂ L(-1) for all lamps. The difference between experimental tests and modeling may be due to TiO₂ particles aggregation. Comparative kinetic tests between solar and solar simulated photocatalytic (SSP) processes using 0.05 g TiO₂ L(-1) in suspension showed a quite similar inactivation behavior up to 30 min of irradiation, but only the SSP process resulted in a total inactivation of bacteria after 60 min of exposure. Antibiotic resistant test (Kirby-Bauer) on survived colonies showed that the SSP and SP processes affected in different ways the resistance of E. coli strain to the target antibiotics.

Abstract
The genus Spiromastix consists of several fungal species that have been isolated from soil and animal dung in various parts of the world. However, these species are considered to be of low pathogenic potential, as no cases of infections caused by these fungi have been reported. Here, we describe the clinical course of discospondylitis in a dog from which a fungus was cultured from a biopsy and identified as a Spiromastix species by morphologic characteristics and sequencing. Phylogenetic analysis determined this to be a new species, Spiromastix asexualis, which is described, and a new order, Spiromastixales, is proposed.

Abstract
Genetic polymorphism studies of cytokines may provide an insight into the understanding of acute kidney injury (AKI) and death in intensive care unit (ICU) patients. The aim of this study was to investigate whether the genetic polymorphisms of -308 G < A tumour necrosis factor (TNF)-α, -174 G > C interleukin (IL)-6 and -1082 G > A IL-10 may predispose ICU patients to the development of AKI and/or death. In a prospective nested case-control study, 303 ICU patients and 244 healthy individuals were evaluated. The study group included ICU patients who developed AKI (n = 139) and 164 ICU patients without AKI. The GG genotype of TNF-α (low producer phenotype) was significantly lower in the with AKI than without AKI groups and healthy individuals (55 versus 62 versus 73%, respectively; P = 0·01). When genotypes were stratified into four categories of TNF-α/IL-10 combinations, it was observed that low TNF-α plus low IL-10 producer phenotypes were more prevalent in patients with AKI, renal replacement therapy and death (P < 0·05). In logistic regression analysis, low TNF-α producer plus low IL-10 producer phenotypes remained as independent risk factors for AKI and/or death [odds ratio (OR) = 2·37, 95% confidence interval (CI): 1·16-4·84; P = 0·02] and for renal replacement therapy (RRT) and/or death (OR = 3·82, 95% CI: 1·19-12·23; P = 0·02). In this study, the combination of low TNF-α plus low IL-10 producer phenotypes was an independent risk factor to AKI and/or death and RRT and/or death in critically ill patients. Our results should be validated in a larger prospective study with long-term follow-up to emphasize the combination of these genotypes as potential risk factors to AKI in critically ill patients.

Abstract
Metal contamination was investigated in soils of the Vallecamonica, an area in the northern part of the Brescia province (Italy), where ferroalloy industries were active for a century until 2001. The extent in which emissions from ferroalloy plants affected metal concentration in soils is not known in this area. In this study, the geogenic and/or anthropogenic origin of metals in soils were estimated. A modified Community Bureau of Reference sequential chemical extraction method followed by inductively coupled plasma optical emission spectroscopy (ICP-OES) analyses were employed to evaluate the potential bioavailability of Al, Cd, Mn, Fe, Cr, Zn, and Pb in soils. Principal component analysis (PCA) was used to assess the relationships among metal sources in soil samples from different locations. This approach allowed distinguishing of different loadings and mobility of metals in soils collected in different areas. Results showed high concentrations and readily extractability of Mn in the Vallecamonica soils, which may suggest potential bioavailability for organisms and may create an environmental risk and potential health risk of human exposure.

Abstract
Pulmonary embolism is the first presentation in 70-80% in patients with aneurysm of popliteal vein. We present a case of young man admitted in our hospital with respiratory distress, tachycardia and D-dimer >3000 mg/dL. The observation of pulmonary embolism required the placement of a caval temporary filter before the surgical treatment. The use of temporary filter is recommended in symptomatic patients for thromboembolic phenomena, and when ultrasound detects the presence of floating thrombus.

Abstract
Endovascular aortic aneurysm repair is an effective alternative to open surgical repair in high risk patient. Endotension is an unpredictable late and rare complication of EVAR. Clinical significance and choice of technique for treatment are controversial. At present, there are no cases of endotension-related aneurysmal sac rupture reported in literature, altough it is frequently associated with late surgical conversion. In this case report is described a case of a patient treated with a first generation Gore Excluder(TM) endograft for abdominal aortic aneurysm, with late aneurysmal sac enlargement without evidence of endoleak and subsequent contained rupture without anemia and shock. We have successfully treated the patient by endovascular procedure, through bilateral percutaneous femoral approach, with relining technique. Three years CT scan follow-up showed the endograft patency and size sac reduction.

Abstract
Urban wastewater treatment plants (UWTPs) are among the main sources of antibiotics' release into various compartments of the environment worldwide. The aim of the present paper is to critically review the fate and removal of various antibiotics in wastewater treatment, focusing on different processes (i.e. biological processes, advanced treatment technologies and disinfection) in view of the current concerns related to the induction of toxic effects in aquatic and terrestrial organisms, and the occurrence of antibiotics that may promote the selection of antibiotic resistance genes and bacteria, as reported in the literature. Where available, estimations of the removal of antibiotics are provided along with the main treatment steps. The removal efficiency during wastewater treatment processes varies and is mainly dependent on a combination of antibiotics' physicochemical properties and the operating conditions of the treatment systems. As a result, the application of alternative techniques including membrane processes, activated carbon adsorption, advanced oxidation processes (AOPs), and combinations of them, which may lead to higher removals, may be necessary before the final disposal of the effluents or their reuse for irrigation or groundwater recharge.

The occurrence of antibiotics may promote the selection of antibiotic resistance genes (ARGs) and antibiotic resistant bacteria (ARB), which shade health risks to humans and animals. In this paper the fate of ARB and ARGs in UWTPs, focusing on different processes/technologies (i.e., biological processes, advanced treatment technologies and disinfection), was critically reviewed. The mechanisms by which biological processes influence the development/selection of ARB and ARGs transfer are still poorly understood. Advanced treatment technologies and disinfection process are regarded as a major tool to control the spread of ARB into the environment. In spite of intense efforts made over the last years to bring solutions to control antibiotic resistance spread in the environment, there are still important gaps to fill in. In particular, it is important to: (i) improve risk assessment studies in order to allow accurate estimates about the maximal abundance of ARB in UWTPs effluents that would not pose risks for human and environmental health; (ii) understand the factors and mechanisms that drive antibiotic resistance maintenance and selection in wastewater habitats. The final objective is to implement wastewater treatment technologies capable of assuring the production of UWTPs effluents with an acceptable level of ARB.

Abstract
ARFI (Acoustic Radiation Force Impulse) is a novel method based on the use of shear acoustic waves remotely induced by the radiation force of a focused ultrasonic beam. Recently, ARFI has been investigated as a non-invasive method for the assessment of liver fibrosis. The reproducibility of ARFI technology was proved in determining liver fibrosis: in detail, for cirrhosis Fibroscan had its best cut-off at >/= 11 kPa (AUROC of 0.80) whereas ARFI >/= 2.0 m/s (AUROC of 0.89). By pair-wise comparison of AUROC, ARFI was significantly more accurate than TE for a diagnosis of significant and severe fibrosis. Due to the low amount of collagen deposition within hepatocellular carcinoma (HCC) nodules in a context of "hard" cirrhotic parenchyma, ARFI propose itself also as a novel, specific method for an early identification of primitive neoplastic nodules during the follow up of cirrhotic patients. The diagnostic accuracy can be demonstrated either versus the surrounding liver tissue or versus dysplastic or metastatic nodules. Further studies are required to confirm ARFI as a useful tool for HCC follow-up.

Abstract
The effect of solar radiation on the inactivation of multidrug resistant Escherichia coli (MDR) strains selected from an urban wastewater treatment plant (UWWTP) effluent and the change of their resistance to a mixture of three antibiotics (evaluated in terms of minimum inhibit concentration (MIC)) in wastewater polluted stream were investigated. The solar photodegradation of the mixture of the three target antibiotics (amoxicillin (AMX), ciprofloxacin (CPX), and sulfamethoxazole (SMZ)) was also evaluated. Additionally, since UWWTP effluents are possible sources of antibiotics and antibiotic resistant bacteria, the disinfection by conventional chlorination process of the UWWTP effluent inoculated with MDR strains was investigated too. Solar radiation poorly affected the inactivation of the two selected antibiotic resistant E. coli strains (40 and 60% after 180 min irradiation). Moreover, solar radiation did not affect strain resistance to AMX (MIC>256 μg/mL) and SMZ (MIC>1024 μg/mL), but affected resistance of the lower resistance strain to CPX (MIC decreased by 33% but only after 180 min of irradiation). Chlorination of wastewater sample strongly decreased the number of the two selected antibiotic resistant E. coli strains (99.667 and 99.999%), after 60 min of contact time at 2.0 mg/L initial chlorine concentration, but the resistance of survived colonies to antibiotics was unchanged. Finally, the solar photodegradation rate of the antibiotic mixture (1mg/L initial concentration respectively) resulted in the following order (half-life time): CPX (t(1/2)=24 min)<AMX (t(1/2)=99 min)<SMZ (t(1/2)=577 min). Accordingly, the risk of the development of resistance to SMZ in surface water is significantly higher compared to CPX and AMX.

Abstract
Patients with symptomatic tight carotid stenosis have an increased short-time risk of stroke and an increased long-term risk of ischaemic vascular events compared with the general population. The aim of this study is to assess the safety, efficacy, and limitations of urgent CEA or CAS, in patients with carotid stenosis greater than 70% and clinically characterized by recurrent TIA or brain damage following a stroke (<2.5 cm). This study involved 28 patients divided into two groups. Group A consisted of sixteen patients who had undergone CEA, and group B consisted of twelve patients who had undergone CAS. Primary endpoints were mortality, neurological morbidity (by NIHSS) and postoperative hemorrhagic cerebral conversion, at 30 days. Ten patients (62.5%) of group A experienced an improvement in their initial neurological deficit while in 4 cases (26%) the deficit remained stable. Two cases of neurologic mortality are presented. At 1 month, 9 patients (75%) of group B experienced an improvement in their initial neurological deficit while 3 patients (25%) had a neurological impairment. Urgent or deferred surgical or endovascular treatment have a satisfactory outcome considering the profile in very high-risk patient population. Otherwise in selected patients CEA seems to be preferred to CAS.

Abstract
A 74-year-old patient was submitted to urgent surgery for intestinal occlusion. After the induction of the anaesthesia, tracheal intubation failed since no progression of Eshmann tracheal tube introducer was possible. The ventilation was difficult and a laryngeal mask was inserted. After oxygenation, the tracheal tube with a rigid catheter was positioned. The larynx was visible but there was a spur that obstacled the progression of the Eshmann tracheal tube introducer. The spur derived from a previous tracheostomy.

Abstract
OBJECTIVES Transient elastography (TE) is adequate for a diagnosis of cirrhosis, but its accuracy for milder stages of fibrosis is much less satisfactory. The objective of this study was to compare the performance and the discordance rate of acoustic radiation force impulse (ARFI) and TE with liver biopsy in a cohort of chronic hepatitis C (CHC) patients. METHODS One hundred thirty-nine consecutive patients with CHC were enrolled in two tertiary centers, and evaluated for histological (Metavir score) and biochemical features. All patients underwent TE and ARFI. RESULTS TE was unreliable in nine patients (6.5%), while in no cases (0%) were ARFI invalid measurements recorded (P=0.029). By area under receiver operating characteristic curve (AUROC), the best cutoff values for TE and ARFI for significant fibrosis (≥F2) were ≥6.5 kPa (AUROC: 0.78) and ≥1.3 m/s (AUROC: 0.86), respectively. For severe fibrosis (F3-F4), these cutoff values were 8.8 kPa (AUROC: 0.83) for TE and 1.7 m/s (AUROC: 0.94) for ARFI. For cirrhosis, TE had its best cutoff at ≥11 kPa (AUROC: 0.80) and ARFI at ≥2.0 m/s (AUROC: 0.89). By pairwise comparison of AUROC, ARFI was significantly more accurate than TE for a diagnosis of significant and severe fibrosis (P=0.024 and P=0.002, respectively), while this difference was only marginal for cirrhosis (P=0.09). By partial AUROC analysis, ARFI performance results significantly higher for all three stages of fibrosis. The average concordance rates of TE and ARFI vs. liver biopsy were 45.4 and 54.7%, respectively. By multivariate analysis, ARFI was not associated with alanine aminotransferase (ALT), body mass index, Metavir grade, and liver steatosis, while TE was significantly correlated with the ALT value (P=0.027). CONCLUSIONS In a cohort of patients with CHC, ARFI imaging was more accurate than TE for the non-invasive staging of both significant and severe classes of liver fibrosis.

Abstract
Solar disinfection (SODIS) of Escherichia coli suspensions in low-density polyethylene bag reactors was investigated as a low-cost disinfection method suitable for application in developing countries. The efficiency of a range of SODIS reactor configurations was examined (single skin (SS), double skin, black-backed single skin, silver-backed single skin (SBSS) and composite-backed single skin) using E. coli suspended in model and real surface water. Titanium dioxide was added to the reactors to improve the efficiency of the SODIS process. The effect of turbidity was also assessed. In addition to viable counts, E. coli injury was characterised through spread-plate analysis using selective and non-selective media. The optimal reactor configuration was determined to be the SBSS bag (t(50)=9.0min) demonstrating the importance of UVA photons, as opposed to infrared in the SODIS disinfection mechanism. Complete inactivation (6.5-log) was achieved in the presence of turbidity (50NTU) using the SBSS bag within 180min simulated solar exposure. The addition of titanium dioxide (0.025gL(-1)) significantly enhanced E. coli inactivation in the SS reactor, with 6-log inactivation observed within 90min simulated solar exposure. During the early stages of both SODIS and photocatalytic disinfection, injured E. coli were detected; however, irreversible injury was caused and re-growth was not observed. Experiments under solar conditions were undertaken with total inactivation (6.5-log) observed in the SS reactor within 240min, incomplete inactivation (4-log) was observed in SODIS bottles exposed to the same solar conditions.

Abstract
Diabetic complications in the lower extremities, especially those secondary to diabetic macroangiopathy, have increasingly become a clinical emergency, given the high prevalence and progression of the disease. Until recently, the only approach to treating advanced stage disease was medical therapy and major amputation; however, the advent of revascularization procedures has radically improved the prognosis of patients with critical lower limb ischemia. In this setting, iloprost holds a dual position: as first-choice therapy in patients ineligible for revascularization and as complementary therapy in candidates for surgical or endovascular revascularization.

Abstract
This randomized trial was done to test the effectiveness and safety of using a novel antiseptic solution (Dermacyn® Wound Care [DWC], Oculus Innovative Sciences, Petaluma, CA) in the management of the postoperative lesions on the infected diabetic foot. 40 patients with postsurgical lesions wider than 5 cm2 left open to heal by secondary intention were randomized into 2 groups. Group A was locally treated with DWC, whereas group B received povidone iodine as local medication, both in adjunct to systemic antibiotic therapy and surgical debridement if needed. Ischemia, renal failure, bilateral lesions, or immunodepression were considered as exclusion criteria. Patients were followed up weekly for 6 months. The primary endpoint was healing rate at 6 months, while secondary endpoints were healing time, time to achieve negative cultures, duration of antibiotic therapy, number of reinterventions, and adverse events. Healing rates at 6 months were significantly shorter in group A (90%) than in group B (55%; P < .01). The time taken for cultures to become negative and duration of antibiotic therapy were also significantly (P < .05) shorter in group A than in group B, whereas the number of reinterventions was significantly higher in group B (P < .05). No difference was noted in the adverse events except that for reinfections, which were more frequent in group B than in group A (P < .01). DWC is as safe as and more effective than standard local antiseptics in the management of wide postsurgical lesions in the infected diabetic foot.

Abstract
The degradation of 15 emerging contaminants (ECs) at low concentrations in simulated and real effluent of municipal wastewater treatment plant with photo-Fenton at unchanged pH and Fe=5 mg L(-1) in a pilot-scale solar CPC reactor was studied. The degradation of those 15 compounds (Acetaminophen, Antipyrine, Atrazine, Caffeine, Carbamazepine, Diclofenac, Flumequine, Hydroxybiphenyl, Ibuprofen, Isoproturon, Ketorolac, Ofloxacin, Progesterone, Sulfamethoxazole and Triclosan), each with an initial concentration of 100 microg L(-1), was found to depend on the presence of CO(3)(2-) and HCO(3)(-) (hydroxyl radicals scavengers) and on the type of water (simulated water, simulated effluent wastewater and real effluent wastewater), but is relatively independent of pH, the type of acid used for release of hydroxyl radicals scavengers and the initial H(2)O(2) concentration used. Toxicity tests with Vibrio fisheri showed that degradation of the compounds in real effluent wastewater led to toxicity increase.

Abstract
The main problem associated with artificial vascular devices is the risk of bacterial infections, mostly sustained by coagulase negative staphylococci or Staphylococcus aureus. Many efforts have been made to identify materials refractory to bacterial adhesion. The aim of our study is to verify the antimicrobial properties of two kinds of vascular prosthesis to prevent early onset infections and the efficacy of the concomitant action of a systemic antibiotic treatment. Adult male Wistar rats were used. We subcutaneously implanted in four groups a silver-coated prosthesis fragment, and a rifampicin-soaked prosthesis fragment in the remaining four groups. We inoculated in the site of implant a high bacterial burden of S. aureus in four groups and a low burden in the remaining groups. Systemic levofloxacin was administered for seven days in four groups representing the two kinds of prosthesis; after 21 days the rats were sacrificed, prosthesis fragments were sonicated and the corresponding supernatants were plated for bacterial counts. The rifampicin-soaked prostheses explanted from rats treated with levofloxacin were sterile, regardless of the bacterial inoculum. In other groups some prostheses were colonized. In the experimental rat model used, the action of local and systemic antibiotic treatment was able to reduce colonisation of artificial prostheses.

Abstract
Degradation kinetics and mineralization of an urban wastewater treatment plant effluent contaminated with a mixture of pharmaceutical compounds composed of amoxicillin (10 mg L(-1)), carbamazepine (5 mg L(-1)) and diclofenac (2.5 mg L(-1)) by TiO(2) photocatalysis were investigated. The photocatalytic effect was investigated using both spiked distilled water and actual wastewater solutions. The process efficiency was evaluated through UV absorbance and TOC measurements. A set of bioassays (Daphnia magna, Pseudokirchneriella subcapitata and Lepidium sativum) was performed to evaluate the potential toxicity of the oxidation intermediates. A pseudo-first order kinetic model was found to fit well the experimental data. The mineralization rate (TOC) of the wastewater contaminated with the pharmaceuticals was found to be really slow (t(1/2)=86.6 min) compared to that of the same pharmaceuticals spiked in distilled water (t(1/2)=46.5 min). The results from the toxicity tests of single pharmaceuticals, their mixture and the wastewater matrix spiked with the pharmaceuticals displayed a general accordance between the responses of the freshwater aquatic species (P. subscapitata>D. magna). In general the photocatalytic treatment did not completely reduce the toxicity under the investigated conditions (maximum catalyst loading and irradiation time 0.8 g TiO(2) L(-1) and 120 min respectively).

Abstract
Neuropathic leg ulcers (NLUs) affect more than 10% of diabetic patients with peripheral neuropathy and represent the most common cause of ulceration of the leg in these patients. Though their pathogenesis is well known, related to the chronic neuropathic edema, the management of NLUs, mainly based on elastocompression, is still controversial, with lower healing rates than nondiabetic venous leg ulcers. The authors tested if a novel gel formulation, containing amino acids and hyaluronic acid (Vulnamin® gel; Errekappa, Milan, Italy), will improve the outcomes of NLUs when used together with elastocompression. Thirty patients affected by NLU were randomized into 2 groups, both treated with 4-layer elastocompressive bandaging: patients in group A were topically treated with the application of Vulnamin® gel, whereas patients in group B received only the inert gel vehicle. The healing rate at 3 months was evaluated as the primary endpoint, whereas the secondary endpoints were healing time, reduction in ulcer area and ulceration score in 4 weeks, number of infective complications, and overall satisfaction of patients. Healing rate was significantly ( P < .05) higher in patients in group A when compared with those in group B; healing time, patients’ satisfaction, and reduction in ulcer area and ulceration score in 4 weeks were also higher in patients in group A. However, no significant differences were found in the prevalence of infections and other adverse events. The use of Vulnamin ® gel with elastocompression is safe and effective in the management of NLUs of diabetic patients.

Abstract
In the present study the degradation kinetics and mineralization of diclofenac (DCF) by the TiO(2) photocatalysis were investigated in terms of UV absorbance and COD measurements for a wide range of initial DCF concentrations (5-80mgL(-1)) and photocatalyst loadings (0.2-1.6gTiO(2)L(-1)) in a batch reactor system. A set of bioassays (Daphnia magna, Pseudokirchneriella subcapitata and Artemia salina) was performed to evaluate the potential detoxification of DCF. A pseudo-first-order kinetic model was found to fit well most of the experimental data, while at high initial DCF concentrations (40 and 80mgL(-1)) and at 1.6gTiO(2)L(-1) photocatalyst loading a second-order kinetic model was found to fit the data better. The toxicity of the treated DCF samples on D. magna and P. subcapitata varied during the oxidation, probably due to the formation of some intermediate products more toxic than DCF. Unicellular freshwater algae was found to be very sensitive to the treated samples as well as the results from D. magna test were consistent to those of algae tests. A. salina was not found to be sensitive under the investigated conditions. Finally, UV absorbance analysis were found to be an useful tool for a fast and easy to perform measurement to get preliminary information on the organic intermediates that are formed during oxidation and also on their disappearance rate.

Abstract
AIM Optimal strategy (staged or combined) for the treatment of patients with concurrent severe carotid and cardiac disease is still controversial. Moreover, carotid artery stenting (CAS), has become a valid alternative to carotid endarterectomy (CEA) and has been proposed for the treatment of cardiac patients. The authors report the preliminary results of a new therapeutic strategy consisting in combined CAS and cardiac surgery. METHODS An initial series of 22 patients underwent combined CAS and cardiac surgery in the same operating room and under general anesthesia. All filter-protected CAS procedures were performed under only heparin and aspirin. A cervical approach (3-cm cervicotomy) was used in patients with documented vessel tortuosity or severe aorto-iliac occlusive arteriopathy. In all the other cases a femoral access was used. A double antiplatelet regimen was initiated in the early postoperative period, once major bleedings were excluded. RESULTS Among the 22 patients who underwent this combined procedure, no deaths, no myocardial infarctions and one controlateral stroke (overall complication rate: 4.5%) were observed. This stroke was observed after transcervical CAS, coronary artery bypass and mitral valve replacement. No major postoperative bleedings nor stent thrombosis were observed. CONCLUSIONS Combined carotid stenting and cardiac surgery, performed in the same operating room under only heparin and aspirin, seems a safe and effective strategy for the treatment of patients with concomitant carotid and cardiac disease.

Abstract
The control of natural organic matter (NOM) in drinking water treatment plants is required in order to control (i) the formation of potentially harmful disinfection byproducts (DBPs), (ii) the regrowth of bacteria and (iii) pipe corrosion in the distribution system. Photocatalysis is a promising advanced oxidation technology due to its ability to mineralise chlorinated byproduct precursors such as humic acids (HAs) to carbon dioxide and water. In this study, the efficiency of HAs and NOM removal in terms of UV absorbance at 254 nm (UV254) was tested by means of a new photocatalytic reactor made of stacked polymethylmethacrylate (PMMA) rings coated by TiO2 nanofilm. Three different sets of rings were coated with TiO2 gel one, two and three times respectively to optimise the coating thickness according to UV254 removal efficiency. The titania sol was immobilised on the substrate by a low temperature procedure and after 8 months the reactors were reactivated by means of UV radiation before the experiments. The photocatalytic removal efficiency of humic acid in terms of UV254 was significantly higher after 1 hour for the reactor employed with high thickness TiO2 nanofilm (around 20%) compared to middle and low thickness reactors (6 and 1.4%, respectively). However, during the same reaction time only 10% of UV254 was removed with high thickness TiO2 nanofilm using raw surface water, probably owing to ionic species naturally occurring in the raw water sample. Finally, the activation of the TiO2 nanofilm may be effectively accomplished by means of UV radiation where calcination cannot be applied (e.g. thermally sensitive substrates).

Abstract
Despite the worldwide increase in Salmonella infections, a Salmonella infection of an aortic graft is an exceptional event. A Salmonella reinfection manifesting as a fistula between the duodenum and an aortic stump pseudoaneurysm 30 months after prosthetic excision, aortic ligature and extra-anatomic bypass for a Salmonella graft infection is a unique event. This unusual late complication described in this case report developed in 1 of the 5 patients whose Salmonella aortic graft infections have been previously reported. The reinfection causing septic aortitis responded to conventional surgery.

Abstract
One of the most common source of lower extremity atheroembolization is the aorta and particularly the infrarenal segment. Complex atherosclerotic plaque can lead the patient to gangrene and major amputation. When the origin of embolization is a focal lesion, endoluminal methods could be an alternative to surgical treatment. Although the experience with aortic stent is limited, the results obtained so far seem to be encouraging. The case of a mid-age heavy smoker woman with a history of the abrupt onset of painfull cyanotic toes in the left foot and subsequent complete gangrene of the first digit in the same foot is herein reported. Angiography and CT scan revealed an high-grade calcified aortic infrarenal plaque. Because of the discrete characteristic of the lesion, an endovascular approach with a Palmaz stent was elected. The stenosis was successfully treated: the patient experienced the complete resolution of the toe painfull cyanosis within 3 months, the stent remained patent through a 24 months follow-up and no subsequent embolic episodes were observed.

Abstract
We report the clinical and neuroradiological features of reversible encephalopathy syndrome and follow-up results in 12 patients. This syndrome seems to be the result of an acute encephalopathy showing with brain edema mainly in the white matter (vasogenic edema). Diffusion-weighted magnetic resonance images are useful to distinguish this entity from acute ischemia. Early recognition and treatment often lead to complete neurological recovery. If unrecognized, the patient's condition can progress to central nervous system failure.

Abstract
The study evaluated prevalence of glycopeptide (vancomycin and teicoplanin) resistant enterococci (VRE) in hospitalized patients and in the community in Calabria (Italy). Rectal swabs were collected from hospitalized and community subjects. Information was gathered on demographics, ward and duration of hospital stay and antibiotics administered; in community subjects information on previous hospitalizations and antibiotics use in the previous year were also collected. Rectal swabs were plated on Enterococcosel agar alone and with addition of vancomycin (6 mg/l) and incubated aerobically at 37 degrees for 24-48 hours. Typical colonies were tested for Gram stain and catalase production. Enterococci were identified to the species level by biochemical tests. Antimicrobial susceptibility test and E-test were performed by the disk diffusion method to evaluate vancomycin and teicoplanin susceptibility. t-test and chi square test were performed to evaluate difference in means and proportions, respectively. Samples were collected from 211 subjects; 132 (62.6%) from community and 79 (37.4%) from hospitals. Enterococci were isolated from 145 subjects (68.7%), 72.7% and 62% in community and in hospital, respectively. The most frequent isolates were E. faecium (30.4%), followed by E. faecalis and E. durans (25.5%), and, finally, by Leuconostoc (18.6%). Only one E. faecium strain was resistant to both vancomycin and teicoplanin, isolated from a non-hospitalized 45 years old woman (1.3%). The results did not show emergence of VRE in our area, although surveillance to confirm these findings is needed, considering the substantial spread of antibiotics in hospitals and in the community.
