Abstract
BACKGROUND Dietary and oral hygiene habits among integrated migrant cultural minorities can vary and could impact susceptibility to caries. AIM This study aimed to assess and compare the oral health status of Tibetan schoolchildren living in the Tibetan settlement of Bylakuppe, India, stratified by type of residence. DESIGN A descriptive cross-sectional study was conducted among Tibetan schoolchildren attending nine schools in the Bylakuppe region. RESULTS The study population consisted of 916 children aged 5-17: 702 (76.6%) living in secular houses (LSH) and 214 (23.4%) living in monasteries (LM). The prevalence of dental caries was 70.9%, and the mean value of decayed, missing, filled teeth for mixed and primary dentition (DMFT*; dmft) of LSH children (1.56 ± 2.34/1.74 ± 2.66) was higher than of LM ones (1.14 ± 2.34/0.83 ± 2.80; p < .001). DMFT for LM children (1.46 ± 2.04) was slightly higher than for LSH children (1.38 ± 1.96; p > .05). Among the sample, 99.1% had a good simplified Oral Hygiene Index (OHI) and LM children showed higher rates of good values (99.5% vs. 98.2% in LSH children). Most children needed preventive/routine dental treatment, whereas 16.6% needed urgent dental treatment. In 4.5% of children, oral mucosal lesions were present. CONCLUSION This study confirms the high need for dental treatment in the children of the Tibetan settlement investigated.

Abstract
Food supplements should not contain substances considered unsafe or pose a health risk to consumers. In recent years illegal adulterants have been found in various functional foods without notification of their presence or amount in the labelling. In this study, a validated method was developed and applied as a screening method to detect 124 forbidden substances belonging to 13 classes of compounds in food supplements. Liquid chromatography coupled with high-resolution mass spectrometry (LC-HRMS) and a simple and rapid extraction protocol was applied to 110 food supplements collected from the internet market or during official controls in Italy. The percentage of non-compliant samples was 4.5%, relatively high compared with the official control results for these substances usually obtained on other food matrices. The results suggested the need to strengthen controls in this field to detect food supplement adulteration, which represents a potential health risk for the consumer.

Abstract
A new, simple and sensitive method for determining and confirming methylene blue and its analogues such as azure A, azure B, azure C, thionine, and new methylene blue in fish muscles have been developed. The method is based on acetonitrile extraction followed by extract purification using dispersive solid-phase extraction (dSPE) with basic aluminium oxide (ALN) and solid-phase extraction (SPE) using primary and secondary amines (PSA) sorbent in matrix adsorption mode. The separation and detection of the dyes in the fish extract are achieved within 5 min by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) using an octadecyl analytical column with a mixture of acetonitrile, methanol and 0.1% formic acid as a mobile phase in gradient elution. The developed method has been in-house validated according to European law. The method recovery for fish muscle was 98.3-103.1%, whereas the decision limit (CCα) was from 0.45 to 0.49 µg kg-1.

Abstract
This study reports the data of polychlorinated dibenzo-p-dioxins (PCDDs), -furans (PCDFs), and polychlorinated biphenyls dioxin-like (dl PCBs) measured in a total of 260 samples of the dairy supply chain collected over a period of 7 years (2011-2017) in the Latium region (Italy). Levels and average profiles of congeners were reported for each group of the analyzed dairy matrices, and any differences between different sampling strategies were considered (around likely pollutant sources or casual sampling). Of the samples, 95.4% resulted compliant with the regulated levels; only samples belonging to the "sheep bulk milk" matrix were found to be above either the action levels or the maximum levels (tot. 12 samples). Raw milk of the sheep species showed the highest averages (PCDD/F 0.248 and dl PCB 0.966 WHO TEQ pg/g of fat) compared to the milk of other species. The buffalo milk showed a content of dl PCB significantly lower (dl PCB: 0.371 WHO TEQ pg/g of fat) than the sheep milk (p<0.05). Dioxins were found to be superior to furans in almost all dairy products, except in the noncompliant samples where furans were higher. The OCDD was found to be the most abundant congener in almost all dairy products. This study provides a first list of reference values for background contamination of the dairy supply chain in the Latium region. These pre-existing values will be useful in all cases of environmental pollution to identify critical situations.

Abstract
Ochratoxin A (OTA) is a mycotoxin produced by several species of Aspergillus and Penicillium and commonly detected in a wide range of foodstuffs. The purpose of this work was to monitor the presence of OTA in cheeses and pork meat products. A simple and accurate "dilute and shoot" method with no need of immunoaffinity column and isotopic labeled internal standard, by liquid chromatography-tandem mass spectrometry, was validated in accordance with the criteria set out in Commission Regulation (EC) No. 401/2006. The method showed good linearity in solvent and in matrix (R2 ≥ 0.995), limit of detection was 0.2 µg/kg for cheese and 0.3 µg/kg for pork meat products, limit of quantification was fixed at 1 µg/kg, and recovery was estimated at two different concentration levels (1 and 5 µg/kg) and ranged from 75% to 101%. The interday and intraday laboratory precisions were lower than 7%. The matrix effect, the recovery of the extraction process, and the overall process efficiency were evaluated. No significant ME was observed in the two matrices considered. This method was applied to the analysis of 75 samples, coming from official controls implemented by the Lazio Region (Central Italy). In one sample of dry-cured ham, the concentration found (69.3 µg/kg) was well above the guidance value recommended by the Italian Ministry of Health (1 µg/kg). These data together with the detection of OTA in three grated cheeses suggest the importance of monitoring these products. Considering the high dietary intake of these matrices, especially among vulnerable populations, further research should be devoted to estimate exposure and risk assessment for OTA.

Abstract
OBJECTIVE In a prospective study, SARS-CoV-2 IgG seroprevalence was assessed during the second pandemic wave (W2) in a cohort of Inflammatory Bowel Disease (IBD) patients using biologics. The secondary aim was to compare, in the same cohort, the frequency of seropositivity and of COVID-19 during the second vs. the first (W1) wave. PATIENTS AND METHODS From November 2020 to March 2021, SARS-CoV-2 IgG seropositivity and the prevalence of COVID-19 were assessed in a cohort of IBD patients using biologics already studied at W1. INCLUSION CRITERIA age ≥ 18 years; diagnosis of IBD; follow-up; written consent. EXCLUSION CRITERIA SARS-CoV-2 vaccination. Risk factors for infection, compatible symptoms, history of infection or COVID-19, nasopharyngeal swab test were recorded. Data were expressed as median [range]. The χ2 test, Student's t-test, logistic regression analysis was used. RESULTS IBD cohort at W1 and W2 included 85 patients: 45 CD (52.9%), 40 UC (47.1%). When comparing the same 85 patients at W2 vs. W1, a higher SARS-CoV-2 seroprevalence at W2 was at the limit of the statistical significance (9.4% vs. 2.3%; p=0.05). The prevalence of COVID-19 at W2 vs. W1 was 3.5% (3/85) vs. 0% (0/85) (p=0.08). Contacts with COVID-19 patients and symptoms compatible with COVID-19 were more frequent at W2 vs. W1 (18.8 % vs. 0%; p=0.0001; 34.1% vs. 15.3%; p=0.004). At W2, history of contacts and new onset diarrhea were more frequent in seropositive patients [4/8 (50%) vs. 12/77 (15.6%); p=0.01 and 4/8 (50%) vs. 2/77 (2.6%); p=0.0001]. At W2, the risk factors for seropositivity included cough, fever, new onset diarrhea, rhinitis, arthromyalgia, dysgeusia/anosmia at univariate (p<0.05), but not at multivariate analysis. History of contacts was the only risk factor for seropositivity at univariate (p=0.03), but not at multivariate analysis (p=0.1). CONCLUSIONS During W2, characterized by a high viral spread, IBD and biologics appeared not to increase the prevalence of SARS-CoV-2 infection or COVID-19 disease. New onset diarrhea mimicking IBD relapse may be observed in patients with SARS-CoV-2 infection.

Abstract
Simple Summary The restriction of the use of bisphenol A (BPA) in industrial production has led manufacturers to employ several BPA analogues. The endocrine-disrupting activity of these substitutes has been proven, and some of them are already widespread in the environment. The intake of these endocrine-disrupting chemicals through diet represents a public concern, and food contamination data are still scarce in scientific literature. To investigate the levels of BPA and its analogues in the production chain of buffalo milk, we developed and validated two analytical methods based on UHPLC–MS/MS and HPLC–FLD. The methods were used to analyse feed and feed additives, raw milk, drinking water, and blood serum samples from buffalo farms in the Campania region, Southern Italy. BPA was found to be the most abundant contaminant, proving that the presence of this compound is still significant and should be monitored. Abstract Bisphenol A (BPA) and some of its analogues are well known as endocrine-disrupting chemicals (EDCs), i.e., compounds that can affect the physiological hormonal pathways in both animals and humans, causing adverse health effects. The intake of these substances through diet represents a public concern, compounded by the scarce data in the literature about contamination levels in food. In the framework of a research project, funded by the Italian Ministry of Health, we determined the contamination levels of BPA and 19 EDCs in the production chain of buffalo milk, analysing feed, drinking water, buffalo milk, and blood sera. Overall, 201 feed, 9 feed additive, 62 drinking water, 46 milk, and 190 blood serum samples were collected from 10 buffalo farms in the Campania region, Southern Italy, between 2019 and 2020, and analysed. Moreover, 15 retail bovine milk samples packaged both in Tetra Pak and in PET were analysed to further evaluate consumers’ exposure to EDCs. The results of our work showed no contamination by EDCs in drinking water samples, whereas in 43% of all of the other samples from the farms at least one bisphenol was detected. The most abundant bisphenol detected was BPA (32% of the samples from the farms and 80% of the retail milk samples), thus proving that this compound is still widely used for plastic production.

Abstract
Nidrâ yoga is an ancient yogic practice capable of inducing altered states of consciousness characterized by deep relaxation, strong concentration, acute self-awareness, and joy. In modern contemplative neuroscience language, it is known by the name yoga nidra, and few studies have investigated its phenomenological and psychophysiological effects. Six healthy volunteers (four females aged 31-74) performed 12 yoga nidra sessions guided by an expert during a 6-day retreat. Each session consisted of 10 minutes in a resting state (baseline) followed by 2 hours of yoga nidra. Psychometric data regarding dissociative experiences (Clinician Administered Dissociative States Scale) and the state of consciousness (Phenomenology of Consciousness Inventory) were collected after baseline and yoga nidra, while high-density EEG was recorded during the entire session. During nidra sessions, no sleep hallmarks (i.e., K-complexes and sleep spindles) were detected by the EEG in any subject. Psychometric data we re analyzed using a Wilcoxon signed-rank test corrected with the false discovery rate approach for multiple comparisons. Compared to baseline, yoga nidra practice was related to: (1) increased dissociative effects (p = 0.022); (2) perception of being in an altered state of consciousness (p = 0.026); (3) alterations in perceived body image (p = 0.022); (4) increased "meaningfulness" attributed to the experience (p = 0.026); (5) reduced rational thinking (p = 0.029); and (6) reduced volitional thought control (p = 0.026). First-person experience is discussed in relation to descriptive EEG power spectral density analysis, which was performed in one subject because of severe EEG artifacts in the other recordings; that subject showed, compared to baseline: (1) early increase of alpha and beta power, followed by a progressive widespread reduction; (2) widespread early increase of theta power, followed by a progressive reduction; and (3) widespread increase of gamma power in the latest stages. The present preliminary results enrich the knowledge of yoga nidra, elucidating its phenomenology and suggesting some psychophysiological correlates that future studies may address.

Abstract
(Poly)phosphates are approved as water-preserving and emulsifying agents that improve the appearance and consistency of many food products. The labelling of added (poly)phosphates is essential for protecting vulnerable population groups and to prevent unfair trade practices resulting in economic fraud. The problems with (poly)phosphates' utilisation concerns both analytical and legislative issues, such as: (1) their straightforward detection; (2) excessive addition altering freshness perception and misleading consumers; (3) uncontrolled usage increasing foodstuff weight; (4) application in products where they are not permitted; and (5) no indication on the label. Bearing all these issues in mind, the main purpose of this study was the quantification and screening of the (poly)phosphates profile in meat, marine and dairy products (160 samples), of which 43 were without declared (poly)phosphate treatment. Analysis was completed by high-performance ion-exchange chromatography either with conductometric detection or coupled to Q-Exactive Orbitrap high-resolution mass spectrometry. Although the (poly)phosphates profiles varied greatly according to species and processing type, the following criteria for detection of illicit treatment were established: high orthophosphate level, quantified short-chain (poly)phosphate anions and the presence of long-chain forms. In conclusion, the instrumental platforms used in this study can be recommended to inspection bodies as reliable methods for the detection of food adulteration with (poly)phosphates.

Abstract
A thresher shark poached by fishermen in the stretch of sea between the island of Ponza and the coast of Terracina (Lazio, Central Italy, Mediterranean Sea) and confiscated by the Italian health authorities was evaluated for the presence of chemical contaminants. Hg mean concentration of 2.1 mg kg-1 was found in muscle; speciation analysis confirmed it was almost in the toxic organic form of MeHg (2.0 mg kg-1). The Se:Hg molar ratio was <1 not protective against the toxic effect of Hg. 137Cs was detected at a mean concentration of 0.53 Bq kg-1, and 40K, radioisotope of natural origin was found at 91 Bq kg-1. Dioxins and PCBs were found in the common thresher shark at mean concentrations of 0.012 and 0.088 pg TEQ-WHO g-1 w.w. while NDL PCBs at 4.5 ng g-1 w.w., lower than limits set by European Regulation. The major concern is constituted by the presence of Hg twice the maximum limit set by EU Regulation, then the consumption of thresher shark flesh should be strongly discouraged.

Abstract
Background:Enteropathic Spondyloarthritis (ESpA) belongs to the group of Spondyloarthritis (SpA) typically associated with inflammatory bowel disease (IBD). SpA are divided into axial (ax) or peripheral disease. Ax-SpA are classified as ankylosing spondylitis (AS) and non-radiographic (nr-) axSpA based on the presence or absence of definite structural changes in conventional radiographs (CR).Objectives:Aim of this study was to determine whether comorbidities and gender could lead to a different response rate to TNF-inhibitors (TNFi) in ESpA patients.Methods:ESpA patients treated with TNFi [adalimumab (ADA) or infliximab (IFX)] were retrospectively evaluated between November 2018 and October 2020 and divided in two cohort according to gender. In addition, TNFi treatments line/s, effectiveness and reasons of discontinuations, as inefficacy, intolerance, acute adverse reaction, development of infections and other causes, were evaluated at baseline (T0), at 6 (T6), 12 (T12), and 24 (T24) months of therapy. Patients who were failure to at least two TNFi were considered as “multifailure”. Statistical analyses were performed using chi square/Fisher tests and variance analysis (SPSS software).Results:120 ESpA patients (M 40.52%; F 40.18%) treated with TNFi were evaluated. Clinical and laboratory baseline (T0) characteristics are summarized in Table 1. AS subtype was more common in men (39.5%) than in woman (14.3%) (p=0.03). Concerning comorbidities, hypertension and anemia were more prevalent in men than women (25% vs 9%, p=0.01; 11.6% vs 1.3%, p=0.02, respectively), while thyreopathy and psychiatric disorders were more common in female than male (11.7% vs 0%, p=0.02; 16.9% vs 4.6%, p=0.04, respectively). No difference was observed between genders in distribution of BMI, smokers, disease duration, HLAB27 positivity and presence of extra-articular manifestations. 202 TNFi treatments (50.9% ADA and 24.3% IFX) were evaluated in 120 patients [74 treatments (36.6%) in 43 men; 128 treatments (63.4%) in 77 women]. Considering treatment effectiveness, higher prevalence of failure was observed in woman that in men (67.2% vs 39.2%, p=0.0005). Moreover, women with psychiatric disorders undergone more lines treatment that men (16.8% vs 4.6%, p=0.01, OR=4). On the other hand, men with hypertension, were more multifailure compared with women (25.6% vs 16.3%, p=0.001, OR=3). No other differences according to gender were found.At T6, 7.5% of patients (n=9) had acute adverse reaction (n=1 with ADA; n=8 with IFX); at T12, 14.2% of patients (n=17) had IBD inefficacy. At T24, secondary inefficacy on IBD and/or SpA was the main cause of TNFi discontinuation compared with other causes (58.4% vs 41.6%; p=0.04), mostly in female cohort (40% vs 20% in woman; p=0.04). Analyzing TNFi effectiveness, CRP and HAQ improvement was noted at T6 (p=0.024 and 0.036, respectively), as ASDAS-CRP and BASDAI (p=0.02 and p=0.013, respectively) and maintained in the following evaluations at T12 and T24. At T24, men shown higher PCR and BASDAI improvement compared with women (p=0.036 and p=0.04, respectively).Conclusion:Data suggest that gender and comorbidities could influenced TNFi response in ESpA patients, advising differences among woman and men. Knowledge of these variable represents a major challenge for a personalized treatment management.Disclosure of Interests:None declared.

Abstract
Gram-positive anaerobic cocci (GPAC) are responsible for 30% of anaerobic infections. Parvimonas micra is an emergent pathogen that is part of the oral and gastrointestinal commensal flora, and its role in several infection processes has recently emerged thanks to the improvement of diagnostic techniques. P. micra bacteraemia is reported in immunocompromised patients and is often complicated by abscesses. Here, we present a case study of multiple hepatic and brain abscesses caused by P. micra bacteraemia in a patient with complicated diverticulitis.

Abstract
OBJECTIVE Treatments used in Inflammatory Bowel Disease (IBD) have been associated with enhanced risk of viral infections and viral reactivation, however, it remains unclear whether IBD patients have increased risk of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. The aim of the study was to examine the prevalence of SARS-CoV-2 IgG positivity in IBD patients followed at our referral center. The role of treatments for IBD and risk factors for infection were also evaluated. PATIENTS AND METHODS In a prospective study, all IBD patients followed at our referral centre between May 27th and July 21st, 2020 and fulfilling the inclusion criteria were tested for SARS-CoV-2 IgG. Specific IgG antibodies were evaluated by a commercial ELISA kit and SARS-CoV-2 nasopharyngeal swab was performed in seropositive patients. RESULTS Two-hundred and eighteen patients, 128 Crohn's disease (CD) and 90 Ulcerative colitis (UC) [age 44, (19-77) years; ongoing biologics in 115 (52.7%)] were enrolled. No patient had major SARS-CoV-2-related symptoms. SARS-CoV-2 IgG were detected in 3 out of 218 (1.37%) patients with IBD (2 CD and 1 UC), all on biologics (2.6%). In all of the 3 seropositive patients, the nasopharyngeal swab was negative. There was no relationship between SARS-CoV-2 seroprevalence and the demographic/clinical characteristics of IBD patients. In contrast, history of recent travel was more frequent in the SARS-CoV-2 seropositive patients (2/3; 66.6%) than in SARS-CoV-2 seronegative patients [7/215 (3.25%); p<0.0001]. CONCLUSIONS The prevalence of SARS-CoV-2 IgG seropositivity in IBD patients appears to be comparable to the non-IBD population and not influenced by ongoing treatments. Risk factors for infection common to the general non-IBD population should be considered when managing patients with IBD.

Abstract
INTRODUCTION Turmeric is the common name for the rhizome of Curcuma longa L. In the recent years, food supplements containing turmeric have been marketed and widely used by an increasing number of consumers. Spontaneous reports of suspected adverse reactions to food supplements are collected within the Phytovigilance system. METHODS An ad hoc multidisciplinary group investigated the suspected cases of hepatotoxicity reported to the Italian Phytovigilance system associated with the assumption of turmeric food supplements with the methodology specific to pharmacovigilance as well as for the evaluation of the quality and safety of food supplements. RESULTS A cluster of 28 spontaneous reports of acute hepatitis, mostly with cholestasis, associated with turmeric products were sent to the Italian Phytovigilance system in the first six months of 2019. In all cases, except one, the causality assessment was at least possible. The suspected products were collected and analysed for the presence of drugs, heavy metals, aflatoxins, pesticides, synthetic dyes and pyrrolizidine alkaloids. CONCLUSION On the basis of the results of all the activities performed by multidisciplinary group, regulatory intervention was taken. This study highlights the importance of developing an integrated evaluation approach for the evaluation of the adverse effects associated with the use of food supplements.

Abstract
OBJECTIVE Crohn's Disease (CD) has been associated with non-Hodgkin lymphoma. Follicular Lymphoma (FL) limited to the liver is extremely rare, accounting for 1% to 4.4% of all Primary Hepatic Lymphoma (PHL). CASE PRESENTATION In 2018, an 85-years old male patient with post-operative recurrence of ileal CD referred rare episodes of fever and mild diffuse abdominal pain. Since cholecystectomy in 2001, clinical history was characterized by recurrent episodes of cholangitis and common bile duct stones. In 2018, ultrasonography and MRI showed a solid focal hepatic lesion (FHL)(4.5 cm x 2.5 cm) in the IV hepatic segment. The radiographic aspect of the lesion was unusual. Initially, focal nodular hyperplasia was suspected. Clinical history of cholangitis and radiological findings subsequently suggested a diagnosis of Hepatic Abscess (HA). A progressive enlargement of the FHL (7.3 cm x 5.8 cm) despite antibiotic treatments, led to perform a liver biopsy. Histological and immunophenotypical analysis of the FHL (7.5 cm x 5.4 cm) enabled a final diagnosis of FL. The "in situ" hybridization for Epstein-Barr virus (EBER) was negative. No additional lesions related to FL were initially detected, thus suggesting a very rare case of PHL in an old patient with CD never treated with thiopurines. CONCLUSIONS This case report highlights the need to consider a rare diagnosis of FL of the liver in patients showing a challenging focal hepatic lesion of unknown origin.

Abstract
OBJECTIVES to produce a methodology for the risk ranking of farms located around proven or potential sources of contamination to prioritize the monitoring procedures in food production. DESIGN environmental factors that can favour the risk of contamination of products of animal origin (POAO) around a pollutant source were identified. A scale of standardized scores was produced for each risk factor (RF) in order to obtain a risk-based classification. Subsequently, an algorithm was developed to obtain a relative risk assessment (RRA). SETTING AND PARTICIPANTS in order to validate the proposed methodology, data of 80 livestock farms in a polluted area, enrolled in a previous study, were subjected to the RRA. Results of RRA were compared with contamination data. MAIN OUTCOME MEASURES seven RFs were included in a mathematical formula used to classify each farm. RESULTS a scoring system was produced for each RFs and an algorithm was developed to obtain RRA which is an estimate of the farm probability of having POAO contamination in comparison to other farms located in the same area potentially affected by chemical pollution based exclusively on site-specific environmental characteristics. In the case study used for validation, a significant relationship between RRA and contamination data was found. CONCLUSIONS the proposed methodology is a useful tool to support the authorities responsible for the food safety in carrying out the monitoring of POAO in areas subject to environmental risks. It helps to rationalize resources and make controls more effective.

Abstract
Biomonitoring has been used to disclose the public health impact of contaminated sites. This study aimed at setting up good practices to apply biomonitoring targeting animal matrixes to design risk-based surveillance and exposure assessment plans. A nine-step protocol targeting farmed animals was devised and tested in three case study areas including (1) a waste dump, (2) a waste incinerator, and (3) a secondary aluminum smelter. Between 2010 and 2012, in each study area, the following 9-step best practices were applied: hazard identification, GIS project creation, risk area delimitation, control area selection, receptors (livestock) identification, farms and matrixes selection, sampling study design, on-farm secondary sources exclusion, and statistical and geostatistical analysis. Dairy farms and free-range laying hens were the primary targets: eggs from both risk and control areas and milk from risk areas were sampled and submitted for detection of selected tracking contaminants compatible with the putative sources. Comparison data (risk vs. control) of heavy metal concentrations in eggs were available only for case study 2, whereas egg comparison data of persistent organic pollutants were available for all the risk-control pairs. After taking into account potential secondary sources, no concern from metals was arisen, whereas high concentrations of persistent organic pollutants were detected in all risk areas; however, only for the aluminum smelter case study, the contamination was broad and higher in the risk area compared with the control one. The protocol has proved to be easily applicable and flexible to varying contexts and able to provide helpful data to inform risk management decisions.

Abstract
Among non steroidal anti-inflammatory drugs (NSAIDs) diclofenac is considered the main cause for the decline of vulture populations in the Indian subcontinent since the '90 s. Chemical analysis showed high levels of flunixin (31,350 μg/kg) in beef which three captive Gyps vultures fed on, later dying with severe visceral gout. Levels in dead vultures' organs and tissues ranged from 4 to 38.5 μg/kg. The typical lesions and the concentrations found in beef indicate flunixin as the cause of death. This is the first observational study which correlates the concentration of flunixin in the meat ingested with that found in tissues of vultures.

Abstract
RATIONALE Carry-over is an undesirable contamination from medicated to non-medicated during the production of feedingstuffs. In 2014 the European Parliament and the Council started working to produce a new regulatory act that will fix tolerable levels of drugs by carry-over in non-target feed to have a harmonized practice to evaluate this contamination by veterinary drugs. METHODS We developed a rapid and effective multi-analyte method coupling ultraperformance liquid chromatography to tandem mass spectrometry (UPLC/MS/MS) for the detection of 37 drugs belonging to different classes of antimicrobials (sulfonamides, tetracyclines, macrolides, quinolones, pleuromutilins and streptogramins) in feeds at carry-over levels. The method was in-house validated in the concentration range 0.25-2.0 mg kg-1 , according to the Regulation (UE) 2017/625 requirements and the guideline included in the Commission Decision 2002/657/EC for official methods. RESULTS The UPLC/MS/MS method allows the determination of the antimicrobials in 15 min, by providing results compliant to the criteria established by the European Commission legislation. All the analytes showed a limit of detection (LOD) in the range 2.0-5.0 μg kg-1 and a limit of quantification (LOQ) at 10.0 μg kg-1 ; oxytetracycline, doxycycline, spiramycin and virginiamycin have a higher LOD and LOQ (15.0 μg kg-1 ; 30.0 μg kg-1 , respectively). Recoveries were satisfactory ranging from 90.4% to 103.1%. CONCLUSIONS The method is characterized by an effective clean-up of all drugs without the use of large sample size and organic solvent extraction.

Abstract
Background: The psycho-physiological changes in brain-body interaction observed in most of meditative and relaxing practices rely on voluntary slowing down of breath frequency. However, the identification of mechanisms linking breath control to its psychophysiological effects is still under debate. This systematic review is aimed at unveiling psychophysiological mechanisms underlying slow breathing techniques (<10 breaths/minute) and their effects on healthy subjects. Methods: A systematic search of MEDLINE and SCOPUS databases, using keywords related to both breathing techniques and to their psychophysiological outcomes, focusing on cardio-respiratory and central nervous system, has been conducted. From a pool of 2,461 abstracts only 15 articles met eligibility criteria and were included in the review. The present systematic review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results: The main effects of slow breathing techniques cover autonomic and central nervous systems activities as well as the psychological status. Slow breathing techniques promote autonomic changes increasing Heart Rate Variability and Respiratory Sinus Arrhythmia paralleled by Central Nervous System (CNS) activity modifications. EEG studies show an increase in alpha and a decrease in theta power. Anatomically, the only available fMRI study highlights increased activity in cortical (e.g., prefrontal, motor, and parietal cortices) and subcortical (e.g., pons, thalamus, sub-parabrachial nucleus, periaqueductal gray, and hypothalamus) structures. Psychological/behavioral outputs related to the abovementioned changes are increased comfort, relaxation, pleasantness, vigor and alertness, and reduced symptoms of arousal, anxiety, depression, anger, and confusion. Conclusions: Slow breathing techniques act enhancing autonomic, cerebral and psychological flexibility in a scenario of mutual interactions: we found evidence of links between parasympathetic activity (increased HRV and LF power), CNS activities (increased EEG alpha power and decreased EEG theta power) related to emotional control and psychological well-being in healthy subjects. Our hypothesis considers two different mechanisms for explaining psychophysiological changes induced by voluntary control of slow breathing: one is related to a voluntary regulation of internal bodily states (enteroception), the other is associated to the role of mechanoceptors within the nasal vault in translating slow breathing in a modulation of olfactory bulb activity, which in turn tunes the activity of the entire cortical mantle.

Abstract
The implementation of the European Union strategy for polychlorodibenzo-dioxins and -furans (PCDD/Fs), and dioxin-like polychlorobiphenyls (DL-PCBs) is determining a general reduction of their presence in the environment and in the food chain. The most important route for human exposure to these substances is food consumption and, as a consequence, a progressive decrease of their dietary intake has been observed in the last decades. In this context, it seemed worth updating the PCDD/F and DL-PCB intake estimation for the Italian population. A total of 2659 samples of food of animal and vegetable origin analyzed for PCDD/Fs and DL-PCBs in the period 2013-2016 by accredited official laboratories and the national food consumption database were considered for the dietary intake assessment in different age groups of the Italian general population The median cumulative intake estimates expressed as pg WHO-TEQ/kg body weight per day and computed with a deterministic and a probabilistic approach were 1.40-1.52 for children, 0.82-0.85 for adolescents, and 0.64-0.61 for adults, respectively. Such results confirm the decreasing trend of PCDD/F and DL-PCB dietary intake even though the Tolerable Daily Intake (TDI) value of 2 WHO-TEQ/kg body weight per day is exceeded at the 95th percentile for all age groups, with children as sensitive group. Most contributing food categories to the intake resulted fish, food of vegetable origin, and cheese. A sensitivity analysis was also performed to calculate the target contamination levels able to keep the dietary exposure below the TDI. Computed target levels fall between P50 and P97 of the occurrence distribution of the main food groups, meaning that most of the Italian food production can be considered safe.

Abstract
The immunoradiometric assay “CA 15-3”, recently developed to measure a breast tumor-associated antigen, gave a mean serum value of 13.8 U/ml (S.D. 6.2) for this antigen in 156 non-cancer controls (36 biopsies for a benign breast lesion and 120 healthy controls). Setting a cut-off value of 30 U/ml (specificity 99.3%), only 3 out of 58 primary breast cancer cases were positive. In metastatic breast cancer, 11 out of 33 cases with limited recurrence (33.3%) and 36 out of 56 cases with extensive recurrence (64.3%) gave abnormal values in this assay, above the cut-off point, with an overall sensitivity of 52.8%; the difference between the sensitivity values in the two groups of recurrent cases was statistically significant (P < 0.01). According to the findings of the present study, CA 15-3 has no role in the detection of primary breast cancer, but its usefulness in disease monitoring can be hypothesized, as circulating levels of the antigen seem to be dependent on the tumor mass.

Abstract
BACKGROUND Gastrointestinal stromal tumors are uncommon intra-abdominal tumors. In fewer than 5% of cases, they originate primarily from the mesentery, omentum or peritoneum and these extra-gastrointestinal stromal tumors tend to have characteristics similar to gastrointestinal stromal. CASE REPORT We report a case of extra-gastrointestinal stromal tumor in a 76-year-old male, Eastern Cooperative Oncology Group (ECOG) performance status of 2. Abdominal Computed Tomography (CT) showed multiple non-homogeneous confluent nodules at the level of the greater omentum and mesentery, involving the bladder and rectum, with additional peritoneal nodules in the upper abdomen. In March 2008, the patient started imatinib mesylate at 400 mg/day. Instrumental examinations showed progressive response until thoracic-abdominal CT in February 2012 which documented a complete response. Follow-up ended in October 2013. Treatment with imatinib, in addition to pathological response, provided clinical benefit, a progressive regression of symptoms and improved the patient's ECOG performance status from 2 to 0.

Abstract
Sunitinib, an orally multitargeted tyrosine kinase inhibitor and standard first-line treatment for metastatic renal cell carcinoma, is usually administered on a 6-week schedule. Toxicities reported with this drug are usually of moderate grade, which results in good treatment tolerability and patients' compliance. However, in some cases high-grade or prolonged toxicities require temporary treatment interruption or dose adjustment, possibly resulting in reduced treatment efficacy. We describe three cases of metastatic renal cell carcinoma patients (a 53-year-old male, a 70-year-old woman, and a 65-year-old woman) who received a shortened 3-week sunitinib administration schedule, 2 weeks daily administration followed by 1 week of rest (2/1) due to toxicities developed on the classic 6-week schedule, which would have required a temporary treatment interruption or a dose reduction. Treatment was generally well tolerated with manageable toxicities. A 3-week administration schedule of sunitinib may represent a valid alternative for managing toxicity while maintaining the planned dose intensity over a 6-weeks period of time. Sunitinib may thus be administered using a flexible dosing schedule to meet individual patient needs, achieving better tolerability and maintaining significant response to treatment.

Abstract
UNLABELLED Malnutrition occurs frequently in the elderly with important clinical and functional consequences. Moreover, the treatment of malnutrition in the elderly may be effective if clinical and nutritional interventions are performed in the early stages. Therefore the early identification of the risk of malnutrition using validated and handy tools plays a pivotal role in terms of clinical outcome. Mini Nutritional Assessment (MNA) was validated for this purpose since many years but it is still ongoing the debate over whether the use of different items in certain clinical conditions can be effective without affecting the validity of the nutritional status evaluation. The aim of this study was to assess the agreement between different versions of MNA in the evaluation of nutritional risk in elderly subjects. METHODS 522 subjects, 345 women and 177 men, were recruited from nursing homes or were free living in three different regions in Italy. All subjects underwent a multidimensional geriatric evaluation, addressed especially to nutritional status. We compared three different versions of MNA: the "original" version; a "proportional" MNA (MNA- P) in which the total MNA score was replaced by the ratio between the maximum score that each subject could obtain without including the body mass index (BMI) and the total original MNA score; and a third version in which calf circumference (CC) and mid- upper arm circumference (MAC) were used instead of BMI. RESULTS According to the original MNA, a high prevalence of malnutrition was found out in both genders (26% of women and 16.3% of men); both the versions of MNA, in which BMI was not considered, showed a good predictive value compared to original MNA. In particular, the MNA- P. showed an overall efficiency equal to 89,1% with specificity and positive predictive value respectively equal to 97.5% and 95.2%. MNA- CC- MAC showed even better results in terms of overall efficiency (91.4%), sensitivity (81.1%), specificity (97.1%), positive and negative predictive values (94.2% and 94.4%, respectively). CONCLUSION The different versions of MNA gave similar results in the classifications of subjects and in comparison with nutritional and biochemical parameters. Moreover MNA versions that did not considered BMI seem to be more effective in singling out subjects with risk factors related to malnutrition (disability, reduced strength and calf circumference, anaemia).

Abstract
UNLABELLED Malnutrition occurs frequently in the frailest groups of the population, especially in people who are on a low income and elderly subjects, overall if they are institutionalized. The aim of this study was to assess the prevalence of malnutrition in a sample of elderly people living in different settings and to identify the determinants of malnutrition. METHODS A total of 718 subjects, 472 females (F) and 246 males (M), were recruited from nursing homes or were free living in three different regions in Italy. Nutritional status, depression, social, functional and cognitive status, were evaluated. RESULTS According to the Mini Nutritional Assessment (MNA), a high prevalence of malnutrition was found out in both genders: 26% of F and 16.3% of M were classified as being malnourished (MNA<17); 40.9% of F and 35% of M were at risk of malnutrition (MNA 17-23,5). The prevalence of malnutrition was significantly higher in NH subjects in both sexes. Moreover, a relationship was shown between malnutrition and inability to shop, prepare and cook meals because of a low income, distance from markets or supermarkets as well as impossibility to drive the car or to use public transportation. This study confirms the necessity to routinely perform nutritional status evaluation in elderly subjects, to carry out training courses for health workers (doctors, nurses, psychologists, dietitians), to implement nutritional education of the geriatric population, to develop tools and guidelines for health workers and caregivers, to identify and reduce clinical, functional, social or economic risk factors for malnutrition.

Abstract
OBJECTIVES Sunitinib is the standard care for first-line treatment of metastatic renal cell carcinoma. The aim of this study was to determine whether a sunitinib regimen of 50 mg/day 2-weeks on/1-week off could maintain the same dose-intensity as the standard 4-weeks on/2-weeks off schedule, and provide the same efficacy in terms of objective response, progression-free survival and overall survival, while reducing drug-related toxicity. METHODS A total of 31 patients with metastatic renal cell carcinoma received sunitinib orally at the dose of 50 mg/day in a 2-weeks on/1-week off regimen until disease progression or intolerable toxicities occurred. RESULTS All enrolled patients were assessable in terms of toxicity and response. They received treatment for a median of 16 months (range 2.0-36.0+ months). A total of 13 patients (42%) obtained an objective response; disease stabilization was achieved in 10 patients (32%), whereas eight patients (26%) experienced disease progression. The most important toxicities were anemia, gastrointestinal effects, fatigue and hypertension, but they were all controlled. CONCLUSIONS Sunitinib 50 mg given orally in a 2-weeks on/1-week off regimen can provide a high response rate and avoid drug-related toxicities, achieving the same dose intensity as the standard schedule, and probably longer disease control.

Abstract
UNLABELLED In elderly subjects, past researches have already underlined the role of nutritional status as a basic factor able to influence the prognosis either in acute wards or in rehabilitation and long-term care settings. Aim of the study is that of retrospectively verify, through a multivariate analysis, the factors able to condition mortality in long-term care, paying particular attention to the nutritional status. METHODS The survey included 513 patients aged more than 65 years admitted to a long-term care unit during a three years period. Exitus within the first three months of hospitalization was considered the outcome variable, while baseline functional, cognitive, clinical and nutritional status were considered the independent variables eventually related to mortality. RESULTS The univariate analysis found that some variables were significantly correlated with the outcome: comorbidity, ADL, cognitive status, pressure sores, albumin, transferrin, CRP, mucoprotein, cholesterol, cholinesterase, MAMC and MNA. The predictive value of the block model of the logistic regression analysis was 77.9% (specificity = 85.3%, sensitivity = 63.9%). With the forward stepwise analysis only MNA, cholinesterase, CRP and mucoprotein were considered in the final model. In this case the predictive value of the model was 79.3% (specificity = 84.6%, sensitivity = 69.46%).

Abstract
In industrialized Countries malnutrition is a very frequent condition in frail groups of the population, people with low income and elderly subjects above all if institutionalized. The aim of the study is to: analyse the prevalence of malnutrition in a sample of elderly people located in different geographical areas in Italy; identify the psychological, social, economic, environmental, cultural and demographic determinants of malnutrition. The prevalence of malnutrition (estimated through the MNA) is high in both sexes (28% of F and 21.9% of M. Age, institutionalisation, health status, autonomy status, cognitive status and education level are some of the factors that correlate with the presence of malnutrition. Loneliness and poverty seem to have a negative impact on nutritional status but further data are needed to confirm this hypothesis. The data collected confirm the need to activate services dedicated to assess the nutritional status of elderly people, to implement campaigns in particular on food education for the elderly population, to set tools and guide lines for caregivers.

Abstract
BACKGROUND The activity of sunitinib, a multitargeted tyrosine kinase inhibitor with antiangiogenic and antitumor activities, has been explored in several solid malignancies such as breast, lung, prostate and pancreatic cancer. Currently it is approved for the treatment of metastatic renal cell carcinoma and gastrointestinal stromal tumors. Non-small cell lung cancer usually presents at an advanced or metastatic stage at diagnosis. Treatment options are limited for this disease, therefore symptom palliation and patient's quality of life are primary objectives of therapy. CASE REPORT We describe the case of a patient (male, 67 years old) with heavily pre-treated metastatic non-small cell lung carcinoma who received sunitinib according to the following 3-week schedule: 50 mg daily for 2 weeks followed by a 1-week rest. The patient completed six months of therapy achieving a major disease response without high-grade toxicities. CONCLUSION In this case, sunitinib shows promising single-agent activity in pretreated non-small cell lung cancer, with a good toxicity profile and flexible administration schedule.

Abstract
Nandrolone (19-nortestosterone) is an androgenic anabolic steroid illegally used as a growth-promoting agent in animal breeding and as a performance enhancer in athletics. Therefore, its use was officially banned in 1974 by the Medical Commission of the International Olympic Committee (IOC). Following nandrolone administration, the main metabolites in humans are 19-norandrosterone, 19-norethiocolanolone and 19-norepiandrosterone, and their presence in urine is the basis of detecting its abuse. The present work was undertaken to determine, in human urine, nandrolone metabolites (phase I and phase II) by developing and comparing multiresidue liquid chromatography/tandem mass spectrometry (LC/MS/MS) and gas chromatography/mass spectrometry (GC/MS) methods. A double extraction by solid-phase extraction (SPE) was necessary for the complete elimination of the interfering compounds. The proposed methods were also tested on a real positive sample, and they allow us to determine the conjugated/free fractions ratio reducing the risk of false positive or misleading results and they should allow laboratories involved in doping control analysis to monitor the illegal use of steroids. The advantages of LC/MS/MS over GC/MS (which is the technique mainly used) include the elimination of the hydrolysis and derivatization steps: it is known that during enzymatic hydrolysis several steroids can be converted into related compounds and deconjugation is not always 100% effective. The validation parameters for the two methods were similar (limit of quantification (LOQ) <1 ng/mL and percentage coefficient of variance (CV%) <16.4), and both were able to confirm unambiguously all the analytes, thus confirming the validity of both techniques.

Abstract
Androgen-independent prostate carcinoma (AICP) is one of the tumors that continue to respond poorly to chemotherapy. Recently, protocols based on the use of docetaxel have significantly improved survival for patients in this disease. In other types of neoplastic disease, combined therapy with taxanes and anthracycline derivatives has been shown to produce additive effects in terms of growth inhibition, and superior tolerability when associated with weekly administration schedules. These findings prompted us to examine the tolerability and efficacy of weekly treatment of AICP with docetaxel (DOX) plus epirubicin (EPI). We enrolled 35 chemotherapy-naive men with AICP (mean age 72 years, range 68-77) and normal hepatic, renal, and cardiac function. The chemotherapy protocol provided for the IV administration of DOX (30 mg/m2) and EPI (30 mg/m2) on days 1, 8, and 15 every 28 days. Treatment was continued for 6 months or until disease progression and/or unacceptable toxicity was observed. Serum levels of prostate-specific antigen (PSA) were monitored in all patients, and reductions from baseline values of >50% were considered indicative of positive responses to treatment. Thirty-four patients were included in the analysis of toxicity, and objective responses to treatment were assessed in the 28 patients with measurable lesions. Nineteen patients (56%) experienced PSA reductions of >50% that persisted for more than 4 weeks. The response to therapy was classified as complete in 1 of the 28 patients (4%) with measurable disease (at the lymph node level). Thirteen others (13/28, 46%) had partial responses, in nine (32%) the disease remained unchanged, and progression was observed in the remaining five (18%); overall response rate was 50% (CR + PR). Of the 27 patients with pain at the time of enrollment, 16 (59%) experienced pain reduction during treatment. The median time to disease progression was 11.7 months (95% CI: 7.7-15.7) while the median survival time was 18.7 months (95% CI: 12.3-25.1). During the study, four patients developed grade 3 anemia and leukopenia, which was reversible in all cases. Lower grades of asthenia, nausea, vomiting, diarrhea, and peripheral edema were also observed. There were no cases of cardiotoxic effects. Alopecia was frequent but reversible in all cases. The results of this preliminary study indicate that the combined administration of DOX and EPI for treatment of AIPC is effective and well tolerated. The weekly administration of the drug combination appears to be a promising approach to the treatment of these tumors.

Abstract
The overall survival for patients with metastatic melanoma is very poor, with a median survival of 8.5 months. In this Phase II trial, we assessed the efficacy, safety, and tolerability of a sequential biochemotherapy schedule, using dacarbazine as antiblastic agent and immunomodulant doses of interleukin-2 and interferon-alfa. Thirty-one eligible patients with metastatic melanoma received dacarbazine IV as antiblastic therapy and interluekin-2, plus interferon-alfa SC as sequential immunotherapy, for 6 months. Responding and nonprogressing patients were subsequently maintained on immunotherapy treatment for further 6 months. Twenty-nine patients had an adequate trial, and were assessable for both response and toxicities, with a median follow-up of 49 months. The overall response rate was 52 percent (3 CR and 12 PR), SD was 8 (27 percent) and PD were achieved in 6 patients (21 percent). The median survival duration of responders was 28 months, significantly longer (p < 0.001) than the 16 months of nonresponders. Therapy was well tolerated and produced a significant improvement in progressive-free survival. Further studies, thus, are recommended for larger groups of patients not only to confirm these results, but also to apply this biochemotherapy regimen as adjuvant postsurgical treatment in early stages of malignant melanoma.

Abstract
BACKGROUND Currently, no single serum biomarker can reliably differentiate irritable bowel syndrome (IBS) from other functional gastrointestinal disorders or organic diseases of the gastrointestinal tract. AIM To develop and validate a diagnostic test using serum biomarkers to detect IBS. METHODS Ten serum biomarkers were selected from a potential panel of 140 for their ability to differentiate IBS from non-IBS disease in blood samples from patients with IBS, other gastrointestinal disorders and healthy volunteers. A predictive modelling tool was developed to assess patterns and relationships among the 10 serum biomarkers that best differentiated IBS patients from healthy controls and patients with non-IBS gastrointestinal disease. This model was tested in a different cohort of patients and healthy controls (n = 516) to determine the predictive accuracy of differentiating IBS from non-IBS. RESULTS The sensitivity and specificity of the 10-biomarker algorithm for differentiating IBS from non-IBS was 50% and 88% respectively. The positive predictive value was 81%, and the negative predictive value was 64% at 50% IBS prevalence in the validation cohort. Overall accuracy was 70%. CONCLUSIONS Assessing serum biomarker patterns can differentiate IBS from non-IBS with reasonable sensitivity and specificity. Assessing serum biomarkers in an overall diagnostic strategy may allow earlier diagnosis and treatment for patients with IBS.

Abstract
Apoptosis plays a key role in the control of rapidly renewing tissues, such as the hematopoietic system and leukemia cells invariably have abnormalities in one or more apoptotic pathways, determining a survival advantage of these cells and the development of drug resistance. These defects are also frequently associated with a low rate of response to standard chemotherapy and with a poor survival in acute myeloid leukemia (AML). The major form of apoptosis proceeds through the mitochondrial pathway, with the mitochondrial outer membrane permeabilization, leading to the release of proteins normally found in the space between the inner and outer mitochondrial membranes (cytochrome C, AIF and others). Higher levels of anti-apoptosis proteins bcl-2, bcl-x(L), Mcl-1 block permeabilization of the membrane and are reported in AML patients presenting a poor outcome. On the contrary, activated pro-apoptotic bax or bad proteins allow this permeabilization and are correlated to a good prognosis in AML. Defects in the mitochondrial pathway induce multidrug-resistance and confer important prognostic information in AML. High ratios of bcl-2 to bax protein confer a poor prognosis with decreased rates of complete remission and overall survival. The prognostic information from the ratio of the proteins is greater than bcl-2 levels alone. Recently, we confirmed the impressive impact of the bax/bcl-2 ratio, determined by flow cytometry, on AML prognosis (complete remission and overall survival) in 255 AML patients. Bcl-2 down regulation might lower the apoptotic threshold of leukemic cells and, through this mechanism, favor response to chemotherapy. Phase II studies of oblimersen (antisense Bcl-2), cytarabine and daunorubicin or oblimersen plus gentuzumab, a cytotoxic antibody directed against CD33+ cells in relapsed AMLs, showed promising results. Defects in apoptosome proteins, such as APAF-1, are frequent in AML and treatment with 5-aza-2'-deoxycytidine, a specific inhibitor of DNA methylation, restored APAF-1 expression in leukemic cells. In conclusion, targeted therapies that are designed to induce apoptosis in leukemic cells, are the most promising anti-leukemia strategies. The elucidation of the apoptotic machinery and of its defects in AML lays the basis for developing new drugs able to trigger apoptosis and overcome therapy resistance.

Abstract
The remote sensing and the detection of events that may represent a danger for human beings have become more and more important thanks to the latest advances of the technology. A microwave radiometer is a sensor capable to detect a fire or an abnormal increase of the internal temperature of the human body (hyperthermia), or an onset of a cancer, or even meteorological phenomena (forest fires, pollution release, ice formation on road pavement). In this paper, the overview of a wearable low-cost low-power system-on-a-chip (SoaC) 13 GHz passive microwave radiometer in CMOS 90 nm technology is presented. In particular, we focused on its application to the fire detection for civil safeguard. In detail, this sensor has been thought to be inserted into the fireman jacket in order to help the fireman in the detection of a hidden fire behind a door or a wall. The simulation results obtained by Ptolemy system simulation have confirmed the feasibility of such a SoaC microwave radiometer in a low-cost standard silicon technology for temperature remote sensing and, in particular, for its application to the safeguard of emergency operators.

Abstract
The purpose of the study was to evaluate objective response rate, survival and toxicity of the combination of gemcitabine-docetaxel administered on a biweekly schedule as first-line treatment in advanced/relapsed or metastatic urothelial carcinoma. Treatment consisted of the sequenced administration of gemcitabine 1500 mg/m(2) and docetaxel 60 mg/m(2) (2 h intravenous infusion) on days 1, 14 of a 28-day cycle for 6 months. A total of 33 patients, 22 men and 11 women, were enrolled, aged 41-75 years (median 64 years). The majority of patients had a good performance status (94%; status<2). Thirteen patients had locally advanced disease (39%) and 20 metastasic disease (41%). A total of 178 treatment cycles were administered with a median number of 5.4 cycles for a patients (range 2-8). Toxicity was primarily hematologic with the most frequent grade >2 being neutropenia (11%), with three episodes of febrile neutropenia. Anemia and thrombocytopenia were milder and had a lower incidence. The most frequent nonhematological toxicities were alopecia, followed by asthenia. Cardiac and pulmonary toxicity was minimal. No toxic deaths were recorded during study and follow-up. Overall response rate was 53.1%, including four complete responses (12.5%) and 13 partial responses (40.6%), whereas six patients (18.8%) had disease stabilization. Median time to progression was 10.2 months (95% confidence interval: 5.1-13.7), with a median survival of 14.8 months (95% confidence interval: 9.4-20.2) after an observation of 30 months (range 4-30+). The results of this study suggested that combination therapy with gemcitabine and docetaxel administered twice a week is particularly active and well tolerated as first-line treatment in advanced and/or metastatic urothelial carcinoma. Once data are confirmed in a larger study and longer follow-up, the favorable toxicity profile of this regimen may offer an interesting alternative to the cisplatin-based regimen.

Abstract
The association between oxaliplatin and 5-fluorouracil (5-FU) has been extensively reported to improve prognosis of gastric cancer patients. The present study is aimed at evaluating response rate and the toxicity profile of the association with oxaliplatin, 5-FU/lecovorin and epirubicin in gastric cancer patients with locally advanced or metastatic disease. Thirty-six patients have been enrolled and 35 evaluated. The treatment schedule was oxaliplatin (100 mg m(-2)), 5-FU (400 mg m(-2)), leucovorin (40 mg m(-2)) and epirubicin (60 mg m(-2)) intravenously. administered every 3 weeks for 6 months, for a total of 185 therapy cycles . Response rate and toxicity were assessed according to the international WHO criteria. Every patient received a mean of 5.3 therapy cycles in a day-hospital setting. Sixteen of 35 patients (46%) showed an objective response, two complete response and 14 partial response. Median time to progression was 33 weeks with an overall median survival of 49 weeks. During the study, anaemia grade 3 and neutropenia grade 3 were observed in 9 and 11% of patients respectively. A grade 3 periferic sensorial neuropathy was observed in 6% of patients. No life threatening or cardiac toxicity was recorded. The regimen used showed anticancer activity against gastric carcinoma, a tolerable toxicity profile and excellent patient compliance.

Abstract
In animal production, it is consolidated the synthesis and the illegal use of growth promoters of new generation, able to skip routine screening and confirmatory analysis. In this work it is reported the nuclear magnetic resonance (NMR) and the mass spectrometry identification of a probable new adrenergic drug found in a feed premix. The substance was selectively purified on alpha 1 acid glycoprotein affinity columns; then its structure was first achieved by recording the 13C NMR spectrum that gave the total number of carbons of the molecule, successively sorted by DEPT experiments into quaternary, CH, CH2, and CH3 groups. However, the complete assignments of all resonances were derived from the bi-dimensional analysis and the crucial indications from the 1H-13C reverse experiments. Further characterisation was performed by atmospheric pressure chemical ionisation both in positive and negative ion mode, matching the molecular ion and the fragmentation pattern with those of most recently described new adrenergic agonists. After the loss of a ter-butylic group, the structure shows an internal symmetry along with the presence of Chlorine clusters. The proposed formula of the compound, the 8,8'-diamino-9,9'-dichloro-1-terbutyl-1,1',4,4-tetrahydro-5H,5'H-2,2'-bi-1-benzazepine-5,5'-dione, partially resembles that of Zilpaterol for the presence of a heterocyclic ring; Further work is in progress to characterise the structure-activity relationship.

Abstract
We investigated the effects of metastasis, surgery and chemotherapy on both circulating dendritic cells (DCs) and monocyte-derived-DCs (MoDCs) in colorectal cancer (CRC) patients. Metastatic or nonmetastatic CRC patients had significantly reduced DC subsets compared to healthy subjects (p < 0.001). These cells were significantly higher in metastatic than in nonmetastatic patients. MoDCs were significantly lower in metastatic than healthy and nonmetastatic subjects (p < 0.001). Surgically treated patients had nearly one-half circulating DC subsets compared to healthy subjects (p < 0.001) while no difference was found between unoperated and healthy subjects. MoDCs obtained from tumor-bearing were significantly higher than in operated subjects. In both cases, MoDCs were significantly lower than in healthy subjects (p < 0.001). Circulating DCs and MoDCs were significantly lower in CRC patients, with or without chemotherapy, compared to healthy subjects (p < 0.001). Compared to untreated, chemotherapy-treated patients had 30% fewer DC subsets and lower MoDCs. Characterization of circulating DC subsets and MoDCs may elucidate CRC patients' immune system status.
