Abstract
Immunometabolism investigates the intricate relationship between the immune system and cellular metabolism. This study delves into the consequences of mitochondrial frataxin (FXN) depletion, the primary cause of Friedreich's ataxia (FRDA), a debilitating neurodegenerative condition characterized by impaired coordination and muscle control. By using single-cell RNA sequencing, we have identified distinct cellular clusters within the cerebellum of an FRDA mouse model, emphasizing a significant loss in the homeostatic response of microglial cells lacking FXN. Remarkably, these microglia deficient in FXN display heightened reactive responses to inflammatory stimuli. Furthermore, our metabolomic analyses reveal a shift towards glycolysis and itaconate production in these cells. Remarkably, treatment with butyrate counteracts these immunometabolic changes, triggering an antioxidant response via the itaconate-Nrf2-GSH pathways and suppressing the expression of inflammatory genes. Furthermore, we identify Hcar2 (GPR109A) as a mediator involved in restoring the homeostasis of microglia without FXN. Motor function tests conducted on FRDA mice underscore the neuroprotective attributes of butyrate supplementation, enhancing neuromotor performance. In conclusion, our findings elucidate the role of disrupted homeostatic function in cerebellar microglia in the pathogenesis of FRDA. Moreover, they underscore the potential of butyrate to mitigate inflammatory gene expression, correct metabolic imbalances, and improve neuromotor capabilities in FRDA.

Abstract
Cadmium sulfide (CdS)-based photocatalysts are prepared following a hydrothermal procedure (with CdCl2 and thiourea as precursors). The HydroThermal material annealed (CdS-HTa) is crystalline with a band gap of 2.31 eV. Photoelectrochemical investigation indicates a very reducing photo-potential of -0.9 V, which is very similar to that of commercial CdS. CdS-HTa, albeit having similar reducing properties, is more active than commercial CdS in the reductive dehalogenation of 2,2-dichloropropionic acid (dalapon) to propionic acid. Spectroscopic, electro-, and photoelectrochemical investigation show that photocatalytic properties of CdS are correlated to its electronic structure. The reductive dehalogenation of dalapon has a double significance: on one hand, it represents a demanding reductive process for a photocatalyst, and on the other hand, it has a peculiar interest in water treatment because dalapon can be considered a representative molecule of persistent organic pollutants and is one of the most important disinfection by products, whose removal from the water is the final obstacle to its complete reuse. HPLC-MS investigation points out that complete disappearance of dalapon passes through 2-monochloropropionic acid and leads to propionic acid as the final product. CdS-HTa requires very mild working conditions (room temperature, atmospheric pressure, natural pH), and it is stable and recyclable without significant loss of activity.

Abstract
Amyotrophic lateral sclerosis (ALS) is a complex neurodegenerative disease influenced by genetic, epigenetic, and environmental factors, resulting in dysfunction in cellular and molecular pathways. The limited efficacy of current treatments highlights the need for combination therapies targeting multiple aspects of the disease. Niclosamide, an anthelminthic drug listed as an essential medicine, has been repurposed in clinical trials for different diseases due to its anti-inflammatory and anti-fibrotic properties. Niclosamide can inhibit various molecular pathways (e.g., STAT3, mTOR) that are dysregulated in ALS, suggesting its potential to disrupt these altered mechanisms associated with the pathology. We administered niclosamide intraperitoneally to two transgenic murine models, SOD1-G93A and FUS mice, mimicking key pathological processes of ALS. The treatment was initiated at the onset of symptoms, and we assessed disease progression by neurological scores, rotarod and wire tests, and monitored survival. Furthermore, we investigated cellular and molecular mechanisms affected by niclosamide in the spinal cord and muscle of ALS mice. In both models, the administration of niclosamide resulted in a slowdown of disease progression, an increase in survival rates, and an improvement in tissue pathology. This was characterised by reduced gliosis, motor neuron loss, muscle atrophy, and inflammatory pathways. Based on these results, our findings demonstrate that niclosamide can impact multiple pathways involved in ALS. This multi-targeted approach leads to a slowdown in the progression of the disease, positioning niclosamide as a promising candidate for repurposing in the treatment of ALS.

Abstract
Background Despite the end of the health emergency, healthcare professionals are at risk of developing long-term mental health problems. The aim of this study was to observe Burnout symptoms and work motivation among Intensive Care Nurses, one year after admission to the Intensive Care Unit of the last positive SARS-CoV-2 swab patients. Study design A multicenter cross-sectional study design was carried out and a national web-based survey was conducted between April, 2023 and May, 2023 among 21 Italian Intensive Care Units. Methods The survey consisted of single- and multiple-choice questions structured into 3 sections: demographic sample data, Maslach Burnout Inventory Scale for the assessment of Burnout-symptoms and Multidimensional Work Motivation Scale for the assessment of work motivation. Results Four hundred-nine surveyed and questionnaires were included in the study. Of these 272 were male (66.5%). Burnout-related symptoms were identified in at least 79% of ICU nurses. Symptoms of severe Burnout was observed in 169 nurses analysed (41.3%) and they are significantly among nurses who had COVID-19 or positive SARS-COV-2 swab during the pandemic (RR= 1.55; CI= 1.24-1.95, p= .0004) and among nurses with at least one child (RR= 1.37; CI= 1.07-1.76; p= .011). Motivated nurses for the intrinsic motivation's level have been 281 (68.7%). The risk of being intrinsically demotivated is significantly greater among nurses with 5-10 years of work experience (RR= 2.44; CI= 1.48-4.02; p= .0002). Emotional exhaustion was associated in increase in demotivation and introjected estrinsic motivation. Depersonalization was associated with demotivation. Personal accomplishment was associated with increase in external estrinsic motivation and amotivation. Conclusions High level of Burnout has been observed among Italian ICU nurses associated with low work motivation after COVID-19 emergency. Interventions and strategies should be adopted to prevent burnout and improve work motivation.

Abstract
Aortic root dilatation has been proposed as hypertension-mediated organ damage (HMOD). Nevertheless, the role of the aortic root dilatation as a possible additional HMOD is still unclear since studies conducted so far are quite heterogeneous regarding the type of population analyzed, the aortic tract considered, and the type of outcomes accounted for. The aim of the present study is to assess whether the presence of aortic dilatation is associated with strong cardiovascular (CV) events (MACE: heart failure, CV death, stroke, acute coronary syndrome, myocardial revascularization) in a population of patients affected by essential hypertension. Four hundred forty-five hypertensive patients from six Italian hospitals were recruited as part of ARGO-SIIA study1. For all centers, follow-up was obtained by re-contacting all patients by telephone and through the hospital's computer system. Aortic dilatation (AAD) was defined through absolute sex-specific thresholds as in previous studies (41 mm for males, 36 mm for females). Median follow-up was 60 months. AAD was found to be associated with the occurrence of MACE (HR = 4.07 [1.81-9.17], p < 0.001). This result was confirmed after correction for main demographic characteristics such as age, sex and BSA (HR = 2.91 [1.18-7.17], p = 0.020). At penalized Cox regression, age, left atrial dilatation, left ventricular hypertrophy and AAD were identified as best predictor of MACEs and AAD resulted a significant predictor of MACEs even after correction for these confounders (HR = 2.43 [1.02-5.78], p = 0.045). The presence of AAD was found to be associated with an increased risk of MACE independently of for major confounders, including established HMODs.

Abstract
BACKGROUND Risk scores are important tools for the prognostic stratification of pulmonary arterial hypertension (PAH). Their performance and the additional impact of comorbidities across age groups is unknown. METHODS Patients with PAH enrolled from 2001 to 2021 were divided in ≥65 years old vs <65 years old patients. Study outcome was 5-year all-cause mortality. French Pulmonary Hypertension Network (FPHN), FPHN noninvasive, Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension (COMPERA) and Registry to Evaluate Early and Long-term PAH Disease Management (REVEAL 2.0) risk scores were calculated and patients categorized at low, intermediate and high risk. Number of comorbidities was calculated. RESULTS Among 383 patients, 152 (40%) were ≥65 years old. They had more comorbidities (number of comorbidities 2, IQR 1-3, vs 1, IQR 0-2 in <65 years patients). Five-year survival was 63% in ≥65 vs 90% in <65 years. Risk scores correctly discriminated the different classes of risk in the overall cohort and in the older and younger groups. REVEAL 2.0 showed the best accuracy in the total cohort (C-index 0.74, standard error-SE- 0.03) and older (C-index 0.69, SE 0.03) patients, whereas COMPERA 2.0 performed better in younger patients (C-index 0.75, SE 0.08). Number of comorbidities was associated with higher 5-year mortality, and consistently increased the accuracy of risk scores, in younger but not in older patients. CONCLUSIONS Risk scores have similar accuracy in the prognostic stratification of older vs younger PAH patients. REVEAL 2.0 had the best performance in older patients and COMPERA 2.0 had it in younger patients. Comorbidities increased the accuracy of risk scores only in younger patients.

Abstract
Interdigitating dendritic cell sarcoma is a very rare entity in the spectrum of histiocytic and dendritic cell neoplasms that mostly occurs in lymph nodes, generally presenting as solitary lymphadenopathy, but may affect every organ. Among extra nodal sites, cutaneous interdigitating dendritic cell sarcoma is exceedingly rare; to date, only 9 cases have been described in English literature. The mean age at diagnosis was 60 years, with a male-female ratio of 1,5 to 1; clinically, two different modalities of skin presentation have been reported: solitary, represented by a single red-brownish nodular lesion, or diffuse, characterized by multiple nodular lesions in one or more body districts. The extreme rarity of this sarcoma and its morphological similarity to other poorly differentiated tumors may lead to a delay in diagnosis; in particular, cutaneous localization may be difficult to differentiate from follicular dendritic cell sarcoma, Langerhans cell sarcoma, poorly differentiated squamous cell carcinoma and more generally sarcomatoid carcinoma, atypical fibroxanthoma, malignant melanoma and several sarcomas. Immunohistochemistry plays an important role in identifying this rare entity and formulating a correct histological diagnosis, fundamental requirement for choosing the best therapeutic approach. We report herein a further case of an 81-year-old Caucasian woman who presented to the Dermatology Department to remove an asymptomatic skin papule in the left temporal region, clinically diagnosed as dermatofibroma. The overall pathological and immunohistochemical features supported the diagnosis of a malignant dendritic cell tumor, consistent of interdigitating dendritic cell sarcoma.

Abstract
A good photocatalyst maximizes the absorption of excitation light while reducing the recombination of photogenerated carriers. Among visible light responsive materials, CdS has good carrier transport capacity; however, its photostability is poor and limits its use. Here, the synthesis of a new hydrothermal CdS is reported, and post-synthesis annealing determines crystal properties and spectroscopic characteristics. The introduction of sulfur vacancies as intra band gap states is the key factor for the enhancement of photocatalytic activity. In fact, by spectroscopic and photo-electrochemical experiments, we demonstrate that sulfur vacancies act as an electron sink, favoring the charge transfer process to methyl orange. In addition, the studied hydrothermal CdS is characterized by very high stability, thus enabling a visible-light active photocatalyst that is overall recyclable, stable and more efficient than the commercial benchmark.

Abstract
Abstract
Background
Peak ventilation (VEpeak) measured by cardiopulmonary exercise testing (CPX) is a valuable clinical information, especially in patients with pulmonary diseases. Measured values can be compared to maximal voluntary ventilation or to predicted VEpeak calculated by nonexercise equations. However, the FRIEND Registry prediction equation has never been assessed for portability in a Brazilian population sample.
Purpose
To analyze the applicability of the FRIEND registry prediction equation for VEpeak during treadmill CPX in a Brazilian healthy sample.
Methods
Cross-sectional study of subjects assessed by CPX in the Brazilian Midwest region between January/2011 to March/2020. The inclusion criteria were CPX performed on treadmill in healthy individuals aged 20 years or older, and with respiratory exchange ratio ≥1.0. The exclusion criteria were any history of cardiovascular or pulmonary disease, presence of cardiovascular risk factors (such as hypertension, diabetes mellitus, current smoking, and obesity) and abnormalities on CPX. Measured VEpeak values were compared with predicted values calculated using age, sex, and height, according to the FRIEND Registry prediction equation. Variables were described as median and interquartile range. Statistical comparisons between measured and predicted VEpeak were performed using Spearman correlation test, Wilcoxon signed rank test, and Blant-Altman agreement analysis.
Results
During the study period 7,843 CPX were performed and included for study eligibility. After the inclusion and exclusion criteria were applied, 3,544 healthy individuals' assessments were included [1,574 females and 1,970 males, age 39 (33, 47) years]. The measured and predicted VEpeak were, respectively, 76.8 (66.7, 87.4) and 76.2 (68.5, 83.0) L min–1 in females, with significant difference (p=0.004). In males, the measured and predicted VEpeak were, respectively, 123.0 (107.3, 137.3) and 114.8 (107.5, 120.7) L min–1, also with statistical difference (p<0.001). Correlations were significant (p<0.001) for both sexes (r2=0.424 for females and .421 for males) (Figure 1). Average error was lower for females than males, with bias of 1.22 L min–1 (95% limits of agreement: - 26.95 to 29.39) in females and bias of 8.41 L min–1 (95% limits of agreement: −33.04 to 49.87) in males (Figure 2).
Conclusion
Measured VEpeak median values were greater than predicted median values for both sexes, with lower average error in females than in males. The significant average error in males limits the prediction equation applicability in the Brazilian population. Thus, the development of a new Brazilian prediction equation is necessary to better evaluate the variable response during CPX in Brazil.

Abstract
Abstract
Background
The main cause of waste of health resources is represented by overuse of diagnostic and therapeutic procedures. Given its high prevalence and the importance of identifying hypertensive-mediated organ damage, management of patients with arterial hypertension can lead to a lack of appropriateness. The aim of this study was to evaluate the prescriptive appropriateness of non-invasive diagnostic tests (Echocardiography, Carotid ultrasound, ECG exercise testing, 24h Ambulatory blood pressure monitoring) in outpatients referring to an ambulatory of primary cardiovascular prevention.
Methods
559 specialistic ambulatory visits were retrospectively analysed and appropriateness of every prescription was evaluated. An integration of different Italian and European guidelines was used to define appropriateness. Moreover, we evaluated the correlation between prescriptions, appropriateness and clinical characteristics of the population.
Results
During the 559 ambulatory visits analysed, 449 prescriptions were made, including 198 echocardiographies, 148 carotid ultrasound, 85 24h ABPM and 18 ECG exercise testing. The global percentage of appropriate prescriptions was 40.3%. Focusing on each test, appropriateness rate was 49.4% in 24h ABPM, 43.9% in echocardiography, 38.9% in ECG exercise testing and 30.4% in carotid ultrasound. A significant correlation was identified between the age and cardiovascular risk category of patients and the appropriateness of echocardiography, 24h ABPM and carotid ultrasound, and a correlation between appropriateness of echocardiography and the duration of hypertension and the presence of valvular heart disease.
Conclusions
Our study shows a relevant percentage of inappropriate prescriptions of non-invasive cardiologic exams; moreover, there might be a greater lack of appropriateness in young and low risk patients.

Abstract
Abstract
Background
Appropriate exercise prescription for cardiovascular diseases patients is a keystone for efficient and safe cardiovascular rehabilitation (CR). Exercise intensity prescribed according to the first and second ventilatory threshold (VT1 and VT2), identified by cardiopulmonary exercise testing (CPET), is considered the gold-standard method. However, because CPET is often not available, percentages of peak heart rate (%HRpeak) or heart rate reserve (%HRR), according to heart rate (HR) response during a conventional exercise test, are very commonly used.
Purpose
To compare the HR at VT1 and VT2 identified by CPET with the recommended exercise intensity prescription domains according to the Brazilian, American, and European CR guidelines/recommendations.
Methods
This retrospective cohort study assessed 1,465 treadmill CPETs from adult patients with stable cardiovascular diseases. Inclusion criteria were available VT1 and VT2 identification, sinus rhythm during exercise, and had reached maximal effort (respiratory exchange rate ≥1.10). HR at VT1 and VT2 were compared with the exercise intensity prescription domains recommended by Brazilian CR Guideline 2020, European Position Statement 2022, and the American College of Sports Medicine Guideline 2017, according to the obtained %HRpeak and %HRR.
Results
After applying the inclusions criteria, a sample of 972 CPETs were included (mean age 57.7±12.0 years, 80.8% males, 81.4% with coronary artery disease, and 26.6% with heart failure). VT1 and VT2 were identified, respectively, at 68.8% (63.8, 74.7) and 89.1 (85.8, 92.2) of the peak HR, and 39.0 (32.9, 45.8) and 78.0 (71.6, 84.5) of the HR reserve, indicating a greater heterogeneity of the latter (Figure 1). We found substantial heterogeneity between the measured %HRpeak and %HRR correspondent to the VT1 and VT2 and the estimated HR exercise intensity domains by compared international recommendations (Figure 2).
Conclusion
The disparities among currently established guideline-directed exercise domains limits the clinical validity of the use of %HRR and %HRpeak, and further strengthens the importance of performing CPET for an accurate exercise intensity prescription in CR. In the absence of CPET, HR values identified in our study at VT1 and VT2 could be used for guiding moderate-intensity exercise prescription for CVD patients, and the suggested range would be 69 to 89% of %HRpeak or 40 to 78% of %HRR. Current established exercise domains limits should be revised to improve HR-based prescription efficiency and safety.

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq). Background Post-COVID-19 persistent symptoms and exercise intolerance are poorly understood. Cardiopulmonary exercise testing (CPET) assessment is important to address the sources of the underlying symptoms and limitations. Purpose To evaluate the source and magnitude of exercise intolerance in post-COVID-19 subjects via CPET. Methods This cohort study assessed subjects with different SARS-CoV-2 illness severities. The propensity score matching method was used to select the control group. Patients with available CPET prior to SARS-CoV-2 infection were compared before and after COVID-19. Results 288 subjects (144 post-COVID-19 and 144 matched-controls) were assessed. The median age was 43.0 years, and 57% were male, with different illness severity (60.4% mild, 20.8% moderate, 18.8% severe). Residual symptoms were reported in 41% of the sample. CPET was performed 14.4±9.4 weeks after disease onset, with exercise limitations being attributed to the peripheral muscle (91.7%), pulmonary (6.3%), and cardiovascular (2.1%) systems. Lower median percent-predicted peak oxygen consumption was observed in the severe subgroup (72.2%) compared to both mild (98.5%) and control subgroups (91.6%). Peak oxygen consumption (peakVO2), VO2 at the ventilatory thresholds (VO2 at VT), and heart rate differed among illnesses, severities, and controls. Conversely, ventilatory equivalents, oxygen uptake efficiency slope, and peak oxygen pulse were similar (Figure 1). Additional subgroup analysis of 42 subjects with prior CPET revealed changes only on peak treadmill speed in the mild subgroup and additional reductions on peakVO2 and VO2 at VT in the moderate/severe subgroup (Figure 2), while ventilatory equivalents, oxygen uptake efficiency slope, and peak oxygen pulse remained unchanged. Conclusions Peripheral muscle fatigue was the most common etiology of exercise limitation in post-COVID-19 patients regardless of the SARS-CoV-2 illness severity. Our data suggest that treatment should emphasize comprehensive rehabilitation programs, including aerobic and muscle strengthening components.

Abstract
Abstract
Introduction
Cardiorespiratory fitness (CRF) is an important component of health-related physical fitness, and its reduction is associated with a higher risk of cardiovascular disease and increased mortality. Maximal oxygen consumption (VO2 max) measured in the Cardiopulmonary Exercise Test (CPET) is the gold standard for CRF evaluation. The measured VO2 max is compared to predicted normal reference values to provide an accurate and individualized evaluation and classification. However, predicted values have gender and age differences, and data from different regions and countries can be heterogenous due to different demographic and biopsychosocial characteristics.
Purpose
To compare reference values of VO2 max in Brazilian and Norwegian population samples do analyze geographical CRF differences.
Method
Brazilian reference values for CRF were compared within each other and with Norwegian values. The included studies evaluated healthy individual with CPET and direct measurement of VO2 max on a treadmill. Mean, standard deviation and sample size were obtained from the published articles in the last decade, and and standard error of mean (SEM) were calculated. The differences on CRF between studies were analyzed using SEM and the 95% confidence interval.
Results
Brazilian reference values for CRF were different between each other, with lower values at Northeast region and higher values at Southeast for all age groups and both genders. Midwest region showed CRF with intermediate values between these two regions. Comparisons also revealed different values from Norway, which presented the highest CRF for all age groups and both genders (Pictures 1 and 2). Observed heterogeneity in CRF may be explained by anthropometric differences, as Northeast individuals had lower height than the other Brazilian samples, and the Norwegians were the tallest. Other demographic and biopsychosocial characteristics may also play a role.
Conclusion
The present study revealed differences on CRF between countries and within Brazilian population, with a negative gradient from southern to northern regions of Brazil. This finding reinforces the appropriateness of adequate use of regional and country specific reference values for VO2 max to ensure a correct CRF evaluation and classification.

Abstract
The aim of this systematic review was to determinate the true value of C-terminal crosslinking telopeptide test (CTX) in patient who takes Bisphosphonate. A comprehensive search of studies published up to March 2020 and listed in the PubMed/MEDLINE and Cochrane Library databases, was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta- Analyses (PRISMA) guidelines. The search identified 99 publications; 6 studies were finally deemed eligible for inclusion according to the study criteria. These studies included a total 104 patients and was selected 101. The CTX value in the various study groups is less than 150 pg/ml. There is a difference between the age of the patient and the period of taking the drug. This systematic review indicates that the CTX test has diffent predictive value in determining the risk of osteonecrosis in patients taking bisphosphonate compared to previus standard.

Abstract
Background An increasing number of studies evidences that amyotrophic lateral sclerosis (ALS) is characterized by extensive alterations in different cell types and in different regions besides the CNS. We previously reported the upregulation in ALS models of a gene called fibroblast-specific protein-1 or S100A4, recognized as a pro-inflammatory and profibrotic factor. Since inflammation and fibrosis are often mutual-sustaining events that contribute to establish a hostile environment for organ functions, the comprehension of the elements responsible for these interconnected pathways is crucial to disclose novel aspects involved in ALS pathology. Methods Here, we employed fibroblasts derived from ALS patients harboring the C9orf72 hexanucleotide repeat expansion and ALS patients with no mutations in known ALS-associated genes and we downregulated S100A4 using siRNA or the S100A4 transcriptional inhibitor niclosamide. Mice overexpressing human FUS were adopted to assess the effects of niclosamide in vivo on ALS pathology. Results We demonstrated that S100A4 underlies impaired autophagy and a profibrotic phenotype, which characterize ALS fibroblasts. Indeed, its inhibition reduces inflammatory, autophagic, and profibrotic pathways in ALS fibroblasts, and interferes with different markers known as pathogenic in the disease, such as mTOR, SQSTM1/p62, STAT3, α-SMA, and NF-κB. Importantly, niclosamide in vivo treatment of ALS-FUS mice reduces the expression of S100A4, α-SMA, and PDGFRβ in the spinal cord, as well as gliosis in central and peripheral nervous tissues, together with axonal impairment and displays beneficial effects on muscle atrophy, by promoting muscle regeneration and reducing fibrosis. Conclusion Our findings show that S100A4 has a role in ALS-related mechanisms, and that drugs such as niclosamide which are able to target inflammatory and fibrotic pathways could represent promising pharmacological tools for ALS.

Abstract
Introduction: Radical cystectomy (RC) is the gold standard treatment for patients with
muscle-invasive or refractory non-muscle invasive bladder cancer. It is
estimated that approximately 64% and 13% of RC patients experience any
complication and major complications, respectively. Specialized
immunonutrition (SIM) aims to reduce the rates of complications after RC. We
reported surgical complication rates in RC patients who received (SIM group)
versus who did not receive (no-SIM group) perioperative SIM. Moreover, we
investigated factors associated with complications after RC. Material and Methods: This is a retrospective cohort study of 52 patients who underwent RC between
April 2016 and December 2017. Overall, 26 (50%) patients received
perioperative SIM. We recorded age, gender, Charlson Comorbidity Index
(CCI), body mass index (BMI), Malnutrition Universal Screening Tool (MUST)
score, unintentional weight loss (UWL), SIM drinks consume, surgical
approach, urinary diversion, neoadjuvant chemotherapy (NAC), use of total
parenteral nutrition (TPN), final pathology, length of stay (LOS), and
complications. Results: SIM was associated with higher rates of documented infections
(P = .03). Conversely, post-operative ileus was
associated with higher rates of overall infections
(P = .03). Median LOS was comparable within the 2 groups.
Overall, 4 (15.38%) versus 0 (0%) patients in SIM versus no-SIM group were
readmitted to hospital (P = .03). Age, CCI, NAC, and TPN
were not associated with complication rates. Conclusions: SIM is not associated with lower rates of post-operative complications in RC
candidates. Moreover, higher rates of documented infections were observed in
the SIM group. Patients with post-operative ileus experienced more
infections. Age, CCI, NAC, and TPN were not predictive of complications.

Background
Cardiovascular rehabilitation is efficient and safe for patients with coronary artery disease (CAD). Exercises are usually prescribed below the clinic and electrocardiographic ischemic threshold. Training above this threshold remains controversial, given the potential risks compared to the additional benefits. However, clinic and electrocardiographic detection of ischemia has lower accuracy than myocardial perfusion scintigraphy (MPS). Therefore, MPS during physical training can better assess ischemia. Moreover, serial maximum MPS can document the benefits of exercise that can be correlated with ischemia during training.
Purpose
To investigate the presence and clinical significance of scintigraphic myocardial ischemia during aerobic exercise in patients with CAD and ischemic burden.
Methods
Thirty-three patients with stable CAD were evaluated at maximum effort (M1) and at rest (R1) using MPS. Twelve patients were excluded; 3 did not complete the intervention, and 9 did not exhibit ischemia. The remaining 21 patients with ischemic burden were included. The intervention consisted of a 12-week training program of moderate-intensity aerobic exercises, below the clinical and electrocardiographic ischemic threshold. During weeks 1 (T1) and 12 (T2), patients underwent MPS during the exercises. After 12 weeks, patients underwent another MPS at maximum effort (M2). All images were quantitatively analyzed, and the presence, extent, and intensity of ischemia were determined. The Wilcoxon test was used to compare 2 variables, and the Friedman test to compare 3 variables, followed by the post hoc Dunn’s test. Correlations were analyzed using Spearman’s test. The level of significance was set at 5% (p < 0.05).
Results
The prevalence of scintigraphic ischemia during exercise training was 81% at T1 and 71% at T2. The median number (and interquartile range) of ischemic segments at T1 was 3 (2–5), which was significantly different (p = 0.003) from that observed at M1 [5 (3–8)]. The median values of the myocardial uptake in the ischemic segments at R1, T1, and M1 were 59.1% (53.1–68.5), 51.5% (45.3–60.3), and 40.8% (37.3–53.3), respectively, with significant differences between T1 and R1 (p < 0.05) and between T1 and M1 (p < 0.01). After 12 weeks, the extent and intensity of ischemia at maximum effort decreased. The median number of ischemic segments significantly decreased from 5 (3–8) at M1 to 4 (2–6) at M2 (p = 0.005). This reduction in the extent of ischemia after training was significantly correlated with the number of ischemic segments at M1 (r = 0.60; p = 0.004) and at T1 (r = 0.64; p = 0.002), such that patients with more extensive ischemia experienced greater benefits from training.
Conclusions
Scintigraphic ischemia was highly prevalent during moderate-intensity aerobic training in patients with CAD and ischemic burden. There was a correlation between the ischemic stimulus during training and the documented benefits at maximum effort.

Abstract
BACKGROUND AND AIMS Metabolic Syndrome (MS) has been related to an impairment in arterial structural and functional properties with heterogeneous results. In this paper we focused on the effects of MS on arterial carotid-femoral PWV and common carotid IMT in two different populations, one of hypertensive patients and one of healthy controls. METHODS AND RESULTS We enrolled 816 consecutive HT and 536 healthy controls. Vascular structural (IMT) and functional (PWV) properties were evaluated. NCEP-ATP-III criteria were used for diagnosis of MS. MS was diagnosed in 26.9% and 6.9% in hypertensive and control subjects, respectively. PWV was similar in controls with and without MS (7.7 ± 1.9 vs 7.6 ± 1.1 m/s, p = 0.69), while IMT was higher in controls with than those without MS (0.64 ± 0.18 vs 0.57 ± 0.13 mm, p = 0.02). Hypertensives with MS were older (57.9 ± 12.2 vs 52.7 ± 14.1 years, p < 0.001) and showed higher PWV (9.0 ± 2.3 vs 8.4 ± 2.1 m/s, p = 0.001) and IMT (0.72 ± 0.22 vs 0.65 ± 0.17 mm, p < 0.001) than those without MS, however at the age-adjusted analysis only the difference in IMT was confirmed (p = 0.007). Regression models showed that MS was an independent determinant of IMT in both controls (β = 0.08, p = 0.03) and hypertensives (β = 0.08, p = 0.01), but not of PWV either in controls (β = 0.006, p = 0.886 and β = 0.04, p = 0.19, respectively). CONCLUSIONS the main finding of our work is that MS is a significant determinant of IMT while this is not the case for PWV. This result have been confirmed both in hypertensive subjects and in healthy controls.

Background
Echocardiography has been widely used to study cardiac function in patients with end-stage renal disease on hemodialysis (HD), but cardiac function assessment by measuring cardiac dimensions and their rate of change is load dependent, therefore it is influenced by volume depletion. Effects of acute volume reduction on left (LV) and right ventricular (RV) function are still not well understood. Some studies investigated myocardial mechanics after dialysis using speckle tracking echocardiography (STE) but their relative load-dependency makes STE indices unable to account for changes in pre- and afterload. Myocardial work (MW) incorporates both deformation and load into its analysis and is an emerging tool to study LV myocardial function. There are no data about the effects of hemodialysis on LV MW.
Purpose
This study aimed to evaluate acute changes of novel echocardiographic indices of both LV and RV function after a HD session.
Methods
Patients with end-stage renal disease undergoing HD were prospectively enrolled. A transthoracic echo, including STE calculation of LV global longitudinal strain (GLS) and free wall RV strain, was performed before and after hemodialysis. Parameters of MW such as global work index (GWI), global constructive work (GCW), global work efficiency (GWE) and global wasted work (GWW) were quantified using a commercially available software package.
Results
27 patients were enrolled, mean baseline parameters were: LV end-diastolic volume 136 ± 38 mL, LV ejection fraction (LVEF) 56.9 ± 7.5%, LV GLS -17.1 ± 4.1%, RV free wall strain -26.9 ± 5.6%, GWI 2117 ± 602 mmHg%, GCW 2299 ± 633 mmHg%, GWW 137 ± 88 mmHg, GWE 93 ± 3.6%, systolic arterial pressure 145 ± 26 mmHg and diastolic pressure 80 ± 16mmHg. After hemodialysis we observed a significative reduction in LV GLS (p = 0.04), RV strain (p = 0.002), GWI (p = 0.002, Figure I) and GCW (p = 0.004). No significative changes in LVEF and blood pressure were observed. Comparing patients using a LVEF cut-off of 55% (19 patients with LVEF≥55%, 8 patients <55%) we observed a significative reduction of LV GLS (p = 0.004), GWI (p < 0.001), GCW (p < 0.001) only in patients with LVEF ≥55% while RV strain and LV volume showed a reduction in both groups. We observed no significative differences in extracted volumes between the groups (2.6 vs 2.1 liters,p = 0.3). Patients with normal LVEF showed a significative negative variation (D) of LVEF (-1 vs 3%), GWI (-551 vs 38 mmHg%) and GCW (-522 vs 11 mmHg%). Correlations were found between DGWI and extracted volume (r= 0.46, p = 0.01), basal GWI and both DLVEF (r= 0.39, p = 0.04) and DLV GLS (r= 0,42, p = 0.02), basal LV GLS and DLVEF (r= 0.5, p < 0.01).
Conclusions
Our preliminary data show that, immediately after the HD session, there is a reduction in biventricular STE-derived systolic parameters. Patients with normal LV systolic function are more sensitive to acute volume changes and entity of volume depletion seems to be correlated with MW reduction.

Abstract
This study investigates the reliability of a pilot hybrid constructed wetland (H-CW), located in Eastern Sicily (Italy). To address the uncertainty associated with implementing representative monitoring during highly variable storm events, unique to Mediterranean conditions, a recipe for semi-synthetic stormwater was used to evaluate the removal efficiency of the system. This was characterised by metals (Cd, Cr, Fe, Pb, Cu, Zn) and relative concentrations typically found in urban stormwater runoff (SR). Approximately one month of intensive monitoring activities were carried out and quality analyses were conducted on three matrices comprising the pilot H-CW: water, biomass (Canna indica, Typha latifolia), and volcanic gravel substrate. Metal retention in early clogging matter (SS) was also examined. The results showed a significantly high H-CW efficiency for the removal of all metals (70-98%) already at the horizontal flow unit outflow, confirming its strategic role. A metal mass balance analysis was also conducted to describe the retention capacity and influence of each system component on the overall efficiency (ranging from 87.8% for Cr to 99.2% for Pb). Metal removal was mostly related to sediment and substrate processes, while plants exhibited root bioaccumulation and phytostabilisation capacity even with a limited impact on overall system retention. The pilot H-CW exhibits characteristics suitable for the treatment of metal-enriched stormwater runoff and validates the useful application of decentralised natural systems for water resource management.

Abstract
Understanding the fluid-structure interaction is crucial for an optimal design and manufacturing of soft mesoscale materials. Multi-core emulsions are a class of soft fluids assembled from cluster configurations of deformable oil-water double droplets (cores), often employed as building-blocks for the realisation of devices of interest in bio-technology, such as drug-delivery, tissue engineering and regenerative medicine. Here, we study the physics of multi-core emulsions flowing in microfluidic channels and report numerical evidence of a surprisingly rich variety of driven non-equilibrium states (NES), whose formation is caused by a dipolar fluid vortex triggered by the sheared structure of the flow carrier within the microchannel. The observed dynamic regimes range from long-lived NES at low core-area fraction, characterised by a planetary-like motion of the internal drops, to short-lived ones at high core-area fraction, in which a pre-chaotic motion results from multi-body collisions of inner drops, as combined with self-consistent hydrodynamic interactions. The onset of pre-chaotic behavior is marked by transitions of the cores from one vortex to another, a process that we interpret as manifestations of the system to maximize its entropy by filling voids, as they arise dynamically within the capsule.

Abstract
BACKGROUND AND AIM Heterogeneous results have been obtained in the relationship between Uric Acid (UA) and Target Organ Damage (TOD). In the present study we sought to assess the prevalence of hyperuricemia in healthy subjects as well as the role of UA in determining TOD. We evaluated vascular, cardiac and renal TODs in the whole population as well as sub-grouped by gender. METHODS AND RESULTS As many as 379 blood donors participated at the present analysis. TOD was evaluated as Pulse Wave Velocity (PWV), Left Ventricular Mass Index (LVMI) and carotid Intima-Media Thickness (IMT). Hyperuricemia was defined with the classic cut-off (>7.0 in men and >6.0 mg/dL in women) but also with a most recently defined one (5.6 mg/dL for both sex). Hyperuricemia was present in 6.3% of the whole population (7.3% males, 2.8% females) considering the classic cut-off, while, with the recently identified one, it was present in 28.2% of the whole population (37.3% males, 4.7% females). Despite all the evaluated TODs significantly correlated with UA, linear multivariate regression analysis showed that none of them, except for GFR, displayed UA as a significant covariate. Similar figures were found also when both correlation and linear regression analyses were repeated in the two genders separately. CONCLUSIONS Hyperuricemia is an important problem also in healthy subjects and its prevalence could further increase if lower cut-off will be used. In this specific population UA is significantly associated with renal impairment while this was not the case for cardiac and vascular damage.

Abstract
Non-pharmacological treatments have always been considered important in the management of Chronic Coronary Syndromes. Nutraceuticals ("Nutrition" + "Pharmaceutical") could fall both under the definition of non-pharmacological treatment and pharmacological one or, probably more correctly, in the middle of these two kinds of therapies. However, the word "nutraceuticals" never appears in the latest guidelines on this issue. This is probably determined by the fact that evidences on this topic are scarce and most of the published articles are based on preclinical data while translational experiences are available only for some molecules. In this review we will focus on nutraceutical strategies that act on the ischemic myocardium itself and not only on the cardiovascular risk factors. As demonstrated by the important number of papers published in recent years, this is an evolving topic and evaluated substances principally act on two mechanisms (cardiac energetics and ischemia-reperfusion damage) that will be also reviewed.

Abstract
The emergence and rapid spread of multidrug-resistance in human pathogenic microorganisms urgently require the development of novel therapeutic strategies for the treatment of infectious diseases. From this perspective, the antimicrobial properties of the natural plant-derived products may represent an important alternative therapeutic option to synthetic drugs. Among medicinal plants, the Cardiospermum halicacabum L. (C. halicacabum), belonging to Sapindaceae family, could be a very promising candidate for its antimicrobial activity against a wide range of microorganisms, including both Gram-positive and Gram-negative bacteria, as well as fungal pathogens. Although the antimicrobial properties of C. halicacabum have been intensively studied, the mechanism/s by which it exerts the inhibitory activity towards the pathogenic microbes have not yet been completely understood. This review focuses on the main antimicrobial activities displayed in vitro by the plant extract, with particular attention on our recent advances. We demonstrated that C. halicacabum is able to exert in vitro a dose-dependent fungistatic effect against Trychophyton rubrum (T. rubrum) through molecular interaction with the fungal heat shock protein (Hsp)-90 chaperone. These findings are supported by a growing body of research indicating the crucial role played by the Hsp90 in the virulence of the pathogenic microorganisms, including fungal pathogens. The possible future use of C. halicacabum for treating a wide range of infectious diseases is also discussed.

Abstract
RU486 (mifepristone), a glucocorticoid and progesterone receptor antagonist, has been reported to exert antiproliferative effects on tumor cells. Experiments were performed to analyze the effects of RU486 on the proliferation of the human neuroblastoma, both in vitro and in vivo, using the human neuroblastoma SK-N-SH cell line. The exposure in vitro of SK-N-SH cells to RU486 revealed a dose-dependent inhibition of 3H-thymidine incorporation due to a rapid but persistent inhibition of MAPKinase activity and ERK phosphorylation. A significant decrease of SK-N-SH cell number was evident after 3, 6, and 9 days of treatment (up to 40% inhibition), without evident cell death. The inhibitory effect exerted by RU486 was not reversed by the treatment of the cells with dexamethasone or progesterone. Moreover, RU486 induced a shift in SK-N-SH cell phenotypes, with an almost complete disappearance of the neuronal-like and a prevalence of the epithelial-like cell subtypes. Finally, the treatment with RU486 of nude mice carrying a SK-N-SH cell xenograft induced a strong inhibition (up to 80%) of tumor growth. These results indicated a clear effect of RU486 on the growth of SK-N-SH neuroblastoma cells that does not seem to be mediated through the classical steroid receptors. RU486 acted mainly on the more aggressive component of the SK-N-SH cell line and its effect in vivo was achieved at a concentration already used to inhibit oocyte implantation.

Abstract
A key tool for monitoring breast cancer patients under neoadjuvant treatment is the identification of reliable predictive markers. Ki67 has been identified as a prognostic and predictive marker in ER-positive breast cancer. Ninety ER-positive, HER2 negative locally advanced breast cancer patients received letrozole (2.5 mg daily) and cyclophosphamide (50 mg daily) with/without Sorafenib (400 mg/bid daily) for 6 months before undergoing surgery. Ki67 expression and tumor size measured with caliber were determined at baseline, after 30 days of treatment and at the end of treatment. Patients were assigned to a clinical response category according to Response Evaluation Criteria in Solid Tumors, both at 30 days and before surgery and further classified as high-responder and low-responder according to the median variation of Ki67 values between biopsy and 30 days and between biopsy and surgery time. The predictive role of Ki67 and its changes with regard to clinical response and survival was analyzed. No differences in terms of survival outcomes emerged between the arms of treatment, while we observed a higher percentage of women with progression or stable disease in arm with the combination containing Sorafenib (20.5% vs 7.1%, p = 0.06). Clinical complete responders experienced a greater overall variation in Ki67 when compared with partial responders and patients with progressive/stable disease (66.7% vs 30.7%, p = 0.009). High responders showed a better outcome than low responders in terms of both disease-free survival (p = 0.009) and overall survival (p = 0.002). ΔKi67 score evaluated between basal and residual tumor at definitive surgery showed to be highly predictive of clinical complete response, and a potential parameter to be used for predicting disease-free survival and overall survival in luminal breast cancer treated with neoadjuvant endocrine-based therapy.

Abstract
BACKGROUND Endocrine treatment with Tamoxifen and aromatase inhibitors (AIs) is a staple in the management of hormone receptor positive breast cancer (HR + BC). It has become clear that HR + BC carries a consistent risk of relapse up to 15 years post-diagnosis. While increasing evidence supports the use of extended adjuvant Tamoxifen over 5 years, controversial data are available on the optimal duration of extended AIs adjuvant treatment. We performed a meta-analysis to assess the real impact of extended adjuvant therapy with AIs on disease-free survival (DFS). METHODS A literature-based meta-analysis of randomized controlled trials (RCTs) was undertaken. Relevant publications from PubMed, the Cochrane Library, and abstracts from American Society of Clinical Oncology (ASCO) and San Antonio Breast Cancer (SABCS) symposia were searched. Primary and secondary endpoints were Disease Free Survival (DFS) and overall survival (OS) respectively. A subgroup analysis was also performed to elucidate the impact of nodal involvement. RESULTS The pooled analysis revealed a significant increase in DFS in the extended AIs group (hazard ratio (HR): 0.78, 95% CI: 0.68-0.90; P = 0.0006). The subgroup analysis according to nodal status showed a greater DFS benefit with extended AIs in patients with positive nodes (HR = 0.67 versus 0.80). Our analysis also demonstrated no improvement in OS with extended AIs (HR = 0.99, 95%CI: 0.87-1.12; P = 0.84). CONCLUSION This work confirmed the efficacy of extended adjuvant treatment with AIs for HR + early breast cancer, with a 22% increase in DFS, but no impact on OS. Greater efficacy was observed in women with positive nodal status.

Abstract
The overall efficiency of a pilot-scale hybrid constructed wetland (H-CW), located on a retail store's parking area in Eastern Sicily, for alternative treatment of stormwater runoff and of sequential batch reactor (SBR) effluent was evaluated. Experimental activities were focused on system performances, including wastewater (WW) quality and hydraulic monitoring. System design, macrophyte growth and seasonal factors influenced the pilot plant performance. Very high removal efficiency for microbial indicators were reported within the subsurface horizontal flow unit (HF), playing a strategic role for Clostridium perfringens. The algal growth occurred in the free water surface (FWS) unit and inhibited removal efficiencies of total suspended solids (TSS), biochemical oxygen demand (BOD5) and chemical oxygen demand (COD), impairing water quality. The whole H-CW showed good efficiency in trace metals removal, especially for Pb, Zn, and Cu. Preliminary results suggested the reliability of the H-CW technology in decentralised water treatment facilities for enhancing water recovery and reuse.

Abstract
Metronidazole resistance is an important factor related to failure in the treatment of Helicobacter pylori. The mutation in the rdxA and frxA genes is the most important cause of resistance to metronidazole. Since the resistance rate of metronidazole is high in our region, we decided to assess the frequency of these mutations among H. pylori clinical isolates. Antral gastric biopsy specimens were cultured and minimal inhibitory concentrations (MICs) of metronidazole were determined by the E-test method. The rdxA and frxA genes were amplified in all isolates through the use of PCR with the specific primers. PCR products were purified for sequencing. The resultant sequences were compared with the wild type reference sequences to find any possible mutations. According to our findings, the rate of metronidazole resistance was 77%, with the MICs ranging from 0.25-1 µg/ml for metronidazolesensitive group and from 16-256 µg/ml for resistance group. H. pylori isolates containing a single mutation in rdxA or frxA genes demonstrated a low MIC (8-16 µg/ml), while those containing mutations in both genes showed a higher MIC (32-256 µg/ml). In this study, all resistant H. pylori isolates contained single or multiple nucleotide substitutions in the mentioned genes. Nevertheless, no nucleotide substitutions were found in the sensitive clinical isolates. The results of our study showed that the mutations in rdxA are mostly related to metronidazole resistance, and mutations in frxA are able to enhance H. pylori resistance.

Abstract
INTRODUCTION Malignant pleural mesothelioma (MPM) is a rare fatal asbestos-related malignancy originating in the mesothelial cells of the pleura. A platinum-based doublet containing a third-generation antifolate is the front-line standard of care whilst there are no approved second-line treatments for MPM which remains a disease setting to test the efficacy of new therapeutic agents. METHODS Bone marrow mesenchymal stromal cells (BM-MSCs) were loaded with pemetrexed (PMX) and paclitaxel (PTX) according to a standardized procedure. Drug release by both PMX- and PTX-primed BM-MSCs (BM-MSCs/PMX and BM-MSCs/PTX) was tested on the in vitro proliferation of a panel of tumor cell lines including NCI-H28 mesothelioma. RESULTS The in vitro anticancer activity of pure PTX was significantly higher than that of PMX against all the cell lines tested (14.7 times higher than that of PMX against NCI-H28). Whereas BM-MSCs did not take up and release PMX in amounts effective on mesothelioma, PTX-loaded BM-MSCs dramatically inhibited mesothelioma proliferation. CONCLUSIONS PTX-primed mesenchymal stromal cells successfully inhibit the in vitro proliferation of human mesothelioma cells. Further studies and in vivo testing are required to confirm our preliminary in vitro results as a potential new mesothelioma therapy based on cell drug delivery.

Abstract
BACKGROUND Histological status of axillary lymph nodes is an important prognostic factor in patients receiving surgery for breast cancer (BC). Sentinel lymph node (SLN) biopsy (B) has rapidly replaced axillary lymph node dissection (ALND), and is now the standard of care for axillary staging in patients with clinically node-negative (N0) operable BC. The aim of this study is to compare pretreatment lymphoscintigraphy with a post primary systemic treatment (PST) scan in order to reduce the false-negative rates for SLNB. METHODS In this single-institution study we considered 170 consecutive T2-4 N0-1 M0 BC patients treated with anthracycline-based PST. At the time of incisional biopsy, we performed sentinel lymphatic mapping. After PST, all patients repeated lymphoscintigraphy with the same methodology. During definitive surgery we performed further sentinel lymphatic mapping, SLNB and ALND. RESULTS The SLN was removed in 158/170 patients giving an identification rate of 92.9% (95% confidence interval (CI) = 88.0-96.3%) and a false-negative rate of 14.0% (95% CI = 6.3-25.8%). SLNB revealed a sensitivity of 86.0% (95% CI = 74.2-93.7%), an accuracy of 94.9% (95% CI = 90.3-97.8%) and a negative predictive value of 92.7% (95% CI = 86.1-96.8%). CONCLUSION Identification rate, sensitivity and accuracy are in accordance with other studies on SLNB after PST, even after clinically negative node conversion following PST. This study confirms that diagnostic biopsy and neoadjuvant chemotherapy maintain breast lymphatic drainage unaltered.

Abstract
Innovative techniques for the acquisition and analysis of delayed luminescence (DL) signals are proposed and discussed. At a preliminary level, the signals prove to be a useful tool, not only for quantitative analysis, but also for discrimination / among different, possibly competing, mechanisms responsible for DL in photosynthetic organisms. Moreover, DL recordings from non-photosynthetic organisms (S. cerevisiae yeast) with avalanche photodiode (APD) detection will be discussed.

Abstract
Cancerous inhibitor of protein phosphatase 2A (CIP2A) is a predictive biomarker of disease progression in many malignancies, including imatinib-treated chronic myeloid leukemia (CML). Although high CIP2A levels correlate with disease progression in CML, the underlying molecular mechanisms remain elusive. In a screen of diagnostic chronic phase samples from patients with high and low CIP2A protein levels, high CIP2A levels correlate with an antiapoptotic phenotype, characterized by downregulation of proapoptotic BCL-2 family members, including BIM, PUMA and HRK, and upregulation of the antiapoptotic protein BCL-XL. These results suggest that the poor prognosis of patients with high CIP2A levels is due to an antiapoptotic phenotype. Disrupting this antiapoptotic phenotype by inhibition of BCL-XL via RNA interference or A-1331852, a novel, potent and BCL-XL-selective inhibitor, resulted in extensive apoptosis either alone or in combination with imatinib, dasatinib or nilotinib, both in cell lines and in primary CD34(+) cells from patients with high levels of CIP2A. These results demonstrate that BCL-XL is the major antiapoptotic survival protein and may be a novel therapeutic target in CML.

Abstract
AIM Treatment of plantar and periungueal warts (so called "difficult-to-treat" warts, DTW) and external genital warts (EGW) remains unsatisfactory. Medical or invasive procedures are partially effective and/or painful. Furthermore recurrences rates after treatments are still a relevant problem for all the available therapies. Nitric-zinc complex is a solution for topical application containing nitric acid, zinc, copper and organic acids able to induce a caustic effect of the wart trough mummification and proteins denaturation/coagulation action. Nitric-zinc complex has been shown to be an effective and well tolerated treatment of common warts. METHODS We evaluated in a prospective open label 4-centre trial, the efficacy and local tolerability of nitric-zinc complex in the treatment of EGW and DTW. A total of 37 immunocompetent subjects (20 men and 17 women; mean age: 45 years) with single or multiple lesions, were enrolled, after their informed consent. A total of 30 subjects had EGW, 2 subjects had plantar warts, 2 warts of the hand and 3 periungueal lesions. Nitric-zinc aqueous solution was applied topically using a 30 mL capillary tube over the lesions until a whitening/yellowish reaction appeared. A second (or more, if needed) application was performed at two-week interval until a complete clinical cure rate was observed. Primary outcome of the study was the clinical evaluation with picture documentation of the evolution of lesions classified as total cure, partial disappearance or no effect. Topical tolerability was evaluated through patient's reported adverse events. RESULTS All subjects completed the study. A complete cure of lesions was observed in 31 subjects (90%) after one and up to four applications. Three patients with EGW (8%) showed a partial disappearance of lesions and one (2%) subject was no responder to four nitric-zinc complex applications. The product was well tolerated. No serious adverse events were observed or recorded. CONCLUSION Nitric-zinc complex topical solution has shown to be an effective and well tolerated treatment of EGW and "difficult-to-treat" warts with a 90% of subjects with a total cure after one or up to four applications. A total or partial response was observed in 99% of the subjects. Nitric-zinc complex could be considered an easy-to-use effective treatment strategy of "difficult-to-treat" warts and external genital warts. Additional studies comparing nitric-zinc complex to other strategies are warranted.

Abstract
Clarithromycin (CLR) formulation was prepared as PLGA nanoparticles in order to enhance the therapeutic effects using the distinctive features of a nanoparticulate delivery system. CLR loaded PLGA nanoparticles were prepared by Quasi Emulsion Solvent Diffusion (QESD) method using Poly lactic-co-Glycolic Acid (PLGA) as a biodegradable polymer. Antibacterial activity of the prepared formulations was evaluated against clinical strains of Helicobacter pylori, isolated from gastric biopsies of patients with gastritis, duodenal ulcer, peptic ulcer, and gastroesophageal reflux disease undergoing endoscopy, by using agar dilution method.Spherical nanoparticles with relatively narrow size distribution (between 200 and 800 nm) in the size range of 305 ± 138, 344 ± 148 and 362 ± 110 nm were achieved for F22, F23 and F23 respectively. CLR encapsulation percentages were measured to be 57.4 ± 4.3 to 80.2 ± 4.0%. CLR loaded PLGA nanoparticles showed equal or enhanced eradication effect against H. pylori strains according to the declined MIC values in comparison with the untreated CLR.In conclusion, the prepared CLR nanoformulation showed appropriate physicochemical properties and improved activity against H. pylori that could be a suitable candidate for oral preparations.

Abstract
PURPOSE To assess whether the combination of letrozole, metronomic cyclophosphamide and sorafenib (LCS) is well tolerated and shows activity in primary breast cancer (BC). METHODS Thirteen oestrogen receptor-positive, postmenopausal, T2-4, N0-1 BC patients received the LCS combination for 6 months. In these patients we examined the pharmacokinetics of sorafenib and cyclophosphamide, toxicity of the regimen, the clinical response to therapy and changes in the levels of biologically relevant biomarkers. RESULTS Adequate plasma concentrations of sorafenib were achieved in patients when it was dosed in combination with L+C. The mean plasma concentrations of C were consistently lower following administration of LCS, compared with administration of L+C only. The most common drug-related grade 3/4 adverse events were skin rash (69.3%), hand-foot skin reaction (69.3%) and diarrhoea (46.1%). According to RECIST Criteria, a clinical complete response was observed in 6 of 13 patients. A significant reduction in tumour size, evaluated with MRI, was also observed between baseline and 14 days of treatment in all 13 patients (P=0.005). A significant reduction in SUV uptake, measured by (18)FDG-PET/CT, was observed in all patients between baseline and 30 days of treatment (P=0.015) and between baseline and definitive surgery (P=0.0002). Using modified CT Criteria, a response was demonstrated in 8 out of 10 evaluable patients at 30 days and in 11 out of 13 evaluable patients at the definitive surgery. A significant reduction in Ki67 expression was observed in all patients at day 14 compared with baseline (P<0.00001) and in 9 out of 13 patients at the definitive surgery compared with baseline (P<0.03). There was also a significant suppression of CD31 and VEGF-A expression in response to treatment (P=0.01 and P=0.007, respectively). CONCLUSIONS The LCS combination is feasible and tolerable. The tumour response and target biomarker modulation indicate that the combination is clinically and biologically active.

Abstract
Atopic eczema (AE) is a skin disease very common in paediatric population and face region is commonly involved. AE of the face represents a therapeutic challenge limiting the use, especially for long periods, of corticosteroid topical products due to the high risk of atrophic skin changes. Skin barrier alterations and reduction of innate immune mechanisms (reduced levels of anti-microbial peptides) are now considered the hallmarks of AE. Therefore emollient and barrier repair therapies with topical steroid-free substances could be an alternative or an adjuvant strategy in managing AE especially for the face. A non-steroidal, anti-inflammatory moisturizing cream with barrier repair actions, containing rhamnosoft, ceramides and L-isoleucine (ILE) (Nutratopic pro-AMP) has been recently developed for the specific treatment of AE of the face. We report a series of 6 pediatric cases (2 female and 4 male, age from 6 months to 4 years) with facial eczema in children treated with pro-AMP cream for two/four weeks as single treatment, applied twice daily in the affected area with photograph documentation (baseline and after treatment). Pictures of the skin lesions at baseline and after treatment were taken in all cases using a high-definition digital camera. Pro-AMP cream use was associated with a clinical relevant improvement of all signs of eczema. The product was well tolerated. This case series document the clinical efficacy of a barrier repair therapy cream containing rhamnosoft, ceramides and iso-leucine in the treatment of atopic eczema of the face.

Abstract
The article investigates the performance of an integrated system for the energy recovery from biomass and waste based on anaerobic digestion, gasification and water treatment. In the proposed system, the organic fraction of waste of the digestible biomass is fed into an anaerobic digester, while a part of the combustible fraction of the municipal solid waste is gasified. Thus, the obtained biogas and syngas are used as a fuel for running a cogeneration system based on an internal combustion engine to produce electric and thermal power. The waste water produced by the integrated plant is recovered by means of both forward and inverse osmosis. The different processes, as well as the main components of the system, are modelled by means of a lumped and distributed parameter approach and the main outputs of the integrated plant such as the electric and thermal power and the amount of purified water are calculated. Finally, the implementation of the proposed system is evaluated for urban areas with a different number of inhabitants and the relating performance is estimated in terms of the main outputs of the system.

Abstract
Background: Although Trastuzumab has improved survival of HER2+ breast cancer patients, resistance to the agent pre-exists or develops through the course of therapy. Here we show that a specific metabolism and autophagy-related cancer cell phenotype relates to resistance of HER2+ breast cancer to Trastuzumab and chemotherapy. Methods: Twenty-eight patients with locally advanced primary breast cancer were prospectively scheduled to received one cycle of Trastuzumab followed by a new biopsy on day 21, followed by taxol/Trastuzumab chemotherapy for four cycles before surgery. FDG PET/CT scan was used to monitor tumour response. Tissue samples were immunohistochemically analysed for metabolism and autophagy markers. Results: In pre-Trastuzumab biopsies, the LC3A+/HER2+ cell population was correlated with HIF1α expression (P=0.01), while GLUT1 and LC3B expression were correlated with Ki67 proliferation index (P=0.01 and P=0.01, respectively). FDG PET tumour dimensions before therapy were correlated with LC3B expression (P=0.005). Administration of Trastuzumab significantly reduced clinical and PET-detected tumour dimensions (P<0.01). An inverse association of tumour response with the percentage of cells expressing HIF1α at baseline was documented (P=0.01). Administration of Trastuzumab resulted in a decrease of the proliferation index (P=0.004), GLUT1 (P=0.04) and HER2 (P=0.01) expression. In contrast, the percentage of LC3A+/HER2+ cells was increased (P=0.01). High baseline HIF1α expression was the only parameter associated with poorer pathological response to preoperative chemotherapy (P=0.001). Conclusions: As the HER2+/LC3A+ phenotype, which often overexpresses HIF1α, is a major subpopulation increasing after therapy with Trastuzumab, LC3A- and HIF1α-targeting therapies should be investigated for the augmentation of anti-HER2 therapy efficacy.

Abstract
Direct spreading on agricultural lands may represent an environmentally friendly disposal method and a possible use of water and nutrients from olive mill wastewaters (OMWs). However, the agronomic use of OMWs is limited, among others by polyphenols, which exert phytotoxic effects. Activated charcoal (AC) has been recognized as a very effective agent for polyphenol abatement, as it enables an irreversible process of phenol adsorption. Addition of calcium hydroxide (Ca(OH)2) has also been described as a cheap and effective method in polyphenols abatement. However, the effects of Ca(OH)2 addition to OMW on seed germination are unclear. In this paper, the effects of AC and/or Ca(OH)2 on OMW polyphenols abatement, and Lolium multiflorum seed germination have been investigated. The highest polyphenols removal, approximately 95%, was observed when 80 g L(-1) of AC was added to OMWs (the maximum dose in this investigation). The addition of Ca(OH)2 not only improved the effectiveness of the AC treatment but also resulted in a significant rise in Lolium seed germination at the highest AC doses (60 and 80 g L(-1)). Considering the high salinity (7300 μS cm(-1)) of these wastewaters, low quantities of Ca(OH)2 may also exert a protective effect on soil structure counteracting the sodium-induced dispersion through the binding action of calcium cation on clays and organic matter.
