Abstract
Most patients with advanced solid cancers exhibit features of cachexia, a debilitating syndrome characterized by progressive loss of skeletal muscle mass and strength. Because the underlying mechanisms of this multifactorial syndrome are incompletely defined, effective therapeutics have yet to be developed. Here, we show that diminished bone morphogenetic protein (BMP) signaling is observed early in the onset of skeletal muscle wasting associated with cancer cachexia in mouse models and in patients with cancer. Cancer-mediated factors including Activin A and IL-6 trigger the expression of the BMP inhibitor Noggin in muscle, which blocks the actions of BMPs on muscle fibers and motor nerves, subsequently causing disruption of the neuromuscular junction (NMJ), denervation, and muscle wasting. Increasing BMP signaling in the muscles of tumor-bearing mice by gene delivery or pharmacological means can prevent muscle wasting and preserve measures of NMJ function. The data identify perturbed BMP signaling and denervation of muscle fibers as important pathogenic mechanisms of muscle wasting associated with tumor growth. Collectively, these findings present interventions that promote BMP-mediated signaling as an attractive strategy to counteract the loss of functional musculature in patients with cancer.

Abstract
BACKGROUND MicroRNAs (miRNAs) have been proposed as biomarkers in hepatocellular carcinoma (HCC). We aim at evaluating miR-21 and miR-122 in HCC patients treated with drug-eluting beads transarterial chemoembolization (DEB-TACE) as prognostic biomarkers and investigating their correlation with hypoxia inducible factor-1α (HIF-1α) serum levels. METHODS In this retrospective study, 12 healthy subjects, 28 cirrhotics, and 54 HCC patients (tested before and four weeks after DEB-TACE) were included. Whole blood miR-21 and miR-122 levels were measured by quantitative real time (qRT)-PCR, while serum HIF-1α was assessed by an enzyme-linked immunosorbent assay (ELISA) test. RESULTS The highest level of miR-21 was found in cirrhotics, while HCC patients had the highest level of miR-122 (which was even higher in "viral" HCC, p = 0.006). miR-21 ratio (after/before DEB-TACE) and miR-122 below their respective cut-offs identified patients with longer progression-free survival (p = 0.0002 and p = 0.02, respectively). The combined assessment of alpha-fetoprotein and miR-21 ratio, both independent prognostic predictors, identified early progressors among patients with complete or partial radiological response. miR-21 levels positively correlated with HIF-1α before (p = 0.045) and after DEB-TACE (p = 0.035). CONCLUSIONS miR-21 ratio and miR-122 are useful prognostic markers after DEB-TACE. miR-21 correlates with HIF-1α and probably has a role in modulating angiogenesis in HCC.

Abstract
We aimed to explore the activation of monoacylglycerol lipase (MAGL)/cyclooxygenase-2 (COX-2)/prostaglandin E2 (PGE2) axis in hepatocellular carcinoma (HCC), evaluating circulating PGE2 as prognostic biomarker in HCC patients. PGE2 levels were measured in blood samples from 24 cirrhotics, and 34 HCC patients were consecutively collected between January 2016 and December 2017. In a subgroup of patients, tissue expression of MAGL mRNA and immunohistochemistry for MAGL and COX-2 were obtained. Despite tumor tissues showing overexpression of MAGL mRNA and higher levels of both MAGL and COX-2 at immunohistochemistry, PGE2 levels were not significantly different in HCC and cirrhotics. HCC patients with circulating PGE2 levels > 14 pg/mL had a significantly shorter overall survival (19.4 vs. 49.9 months; p = 0.03), the finding being confirmed by the multivariate analysis (HR 3.37 [95% CI 1.00-11.60]; p = 0.05). The MAGL/COX-2/PGE2 axis is activated in HCC, and circulating PGE2 proved to be a potential prognostic biomarker.

Abstract
PURPOSE To perform a systematic review and meta-analysis on the outcome of surgical treatment for isolated local recurrence of pancreatic cancer. METHODS A systematic review and meta-analysis based on Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines was conducted in PubMed, Scopus, and Web of Science. RESULTS Six studies concerning 431 patients with recurrent pancreatic cancer met the inclusion criteria and were included in the analysis: 176 underwent redo surgery, and 255 received non-surgical treatments. Overall survival and post-recurrence survival were significantly longer in the re-resected group (ratio of means (ROM) 1.99; 95% confidence interval (CI), 1.54-2.56, I2 = 75.89%, p = 0.006, and ROM = 2.05; 95% CI, 1.48-2.83, I2 = 76.39%, p = 0.002, respectively) with a median overall survival benefit of 28.7 months (mean difference (MD) 28.7; 95% CI, 10.3-47.0, I2 = 89.27%, p < 0.001) and median survival benefit of 15.2 months after re-resection (MD 15.2; 95% CI, 8.6-21.8, I2 = 58.22%, p = 0.048). CONCLUSION Resection of isolated pancreatic cancer recurrences is safe and feasible and may offer a survival benefit. Selection of patients and assessment of time and site of recurrence are mandatory.

Abstract
At the beginning of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) outbreak in Italy, the cluster of Vò Euganeo was managed by the University Hospital of Padova. The Department of Diagnostic Imaging (DDI) conceived an organizational approach based on three different pathways for low-risk, high-risk, and confirmed Coronavirus Disease 19 (COVID-19) patients to accomplish three main targets: guarantee a safe pathway for non-COVID-19 patients, ensure health personnel safety, and maintain an efficient workload. Thus, an additional pathway was created with the aid of a trailer-mounted Computed Tomography (CT) scanner devoted to positive patients. We evaluated the performance of our approach from February 21 through April 12 in terms of workload (e.g., number of CT examinations) and safety (COVID-19-positive healthcare workers). There was an average of 72.2 and 17.8 COVID-19 patients per day in wards and the Intensive Care Unit (ICU), respectively. A total of 176 high-risk and positive patients were examined. High Resolution Computed Tomography (HRCT) was one of the most common exams, and 24 pulmonary embolism scans were performed. No in-hospital transmission occurred in the DDI neither among patients nor among health personnel. The weekly number of in-patient CT examinations decreased by 27.4%, and the surgical procedures decreased by 29.5%. Patient screening and dedicated diagnostic pathways allowed the maintenance of high standards of care while working in safety.

Abstract
The incidental finding of soft tissue masses is a challenge for the radiologist. Benign and malignant lesions can be differentiated relying on patient history, symptoms and mostly with the help of imaging. Ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) become fundamental in order to distinguish these lesions but the radiologist needs to know the main characteristics of benign soft tissue masses and sarcomas. Herein, we present a pictorial review of lesions mimicking soft tissue sarcomas features.

Laparoscopic distal pancreatectomy (LDP) with or without splenic preservation is increasingly performed for benign or border-line neoplasms of the body and tail of the pancreas. Pancreatic neuroendocrine tumors appear as an excellent indication for laparoscopic resection and this procedure is becoming the gold standard for the surgical treatment of such neoplasms. The safety and advantage of laparoscopic resection over open distal pancreatectomy (ODP) have been proven. In this video, we present a LDP with splenectomy for a neuroendocrine tumor of distal pancreas, with associated wedge resection of a liver nodule. Technical considerations were also discussed.

Abstract
An easy transfer procedure to obtain graphene-based gas sensing devices operating at room temperature (RT) is presented. Starting from chemical vapor deposition-grown graphene on copper foil, we obtained single layer graphene which could be transferred onto arbitrary substrates. In particular, we placed single layer graphene on top of a SiO2/Si substrate with pre-patterned Pt electrodes to realize a chemiresistor gas sensor able to operate at RT. The responses to ammonia (10, 20, 30 ppm) and nitrogen dioxide (1, 2, 3 ppm) are shown at different values of relative humidity, in dark and under 254 nm UV light. In order to check the sensor selectivity, gas response has also been tested towards hydrogen, ethanol, acetone and carbon oxide. Finally, a model based on linear dispersion relation characteristic of graphene, which take into account humidity and UV light effects, has been proposed.

Abstract
A novel technique to lithograph the MoS2 surface is described here. Mechanically exfoliated MoS2 flakes have been patterned with an atomic force microscope tip. After the patterning process, the lithographed areas have been removed by selective chemical etching. The electronic properties of the MoS2 flakes have been analyzed with spatially resolved photoelectron spectroscopy, with tunable incident photon energy, provided by a synchrotron light source. Tens of meV core level shifts can be recorded in relation to the flakes edges, coming from both the exfoliation and from the lithography.

Abstract
AIM The aim of this study was to analyze factors influencing outcomes of surgical management for lower limb acute ischemia. METHODS A retrospective analysis of 490 thromboembolectomies performed in 468 patients was conducted. Perioperative and follow-up results were analyzed. Univariate and multivariate analysis of clinical variables and patients' characteristics for the risk of reocclusion, amputation and mortality at 2 years were performed. Statistical significance was defined as a P value <0.05. RESULTS Cumulative reocclusion, amputation and mortality rates at 24 months were 22.6%, 14.3% and 42.8%, respectively. At univariate analysis, the factors associated with increased 2-year reocclusion rate were severity of clinical presentation, current smoking habit, arterial thrombosis rather than embolism, atrial fibrillation and the avoidance of completion angiography. All these factors except clinical presentation maintained significance at multivariate analysis. Factors associated with increased 2-year amputation rate at univariate analysis included severity of clinical presentation, smoke, arterial thrombosis, atrial fibrillation and valvulopathy. All these factors except clinical presentation and valvular defects maintained significance at multivariate analysis. Factors associated with increased 2-year mortality rate at univariate analysis included age >80 years, arterial thrombosis, history of peripheral arterial disease and antiplatelet drugs. The same factors, except antiplatelet treatment, were found to be significant at multivariate analysis. CONCLUSION Surgical intervention for lower limb ischemia is associated with high 2-year mortality but offers good 2-year limb salvage. The pattern of risk factors for reocclusion and amputation rates is quite different from those affecting mortality. Only thrombotic aetiology is a significant risk factor for all the three outcomes.

Abstract
AIM The objectives were to review in our series the risk factors, management and outcomes of patients who sustained vascular injuries in the lower limbs and to determine the effect of risk factors and treatment on the outcome of the injured extremity. METHODS Fifty-six patients submitted to surgical treatment were retrospectively reviewed. Results were analysed in terms of type of operation and reconstruction, intraoperative and 30 day complications, reconstruction occlusion, major amputation and mortality. RESULTS The mechanism of trauma was blunt in 30.4% and penetrating in 69.6%. The overall primary amputation rate was 5.4%, the overall secondary amputation rate was 1.8%. The overall intraoperative and postoperative mortality were 1.8% and 5.4% respectively. At univariate analysis, the presence of compartment syndrome and ischemia time >6 hours were associated with a significantly higher risk of early reconstruction thrombosis (both P=0.03). It showed also that the number of patent vessels (P=0.0000) and the presence of a MESS score >7 (P=0.0000) significantly affected primary amputation, and that the occurrence of postoperative deep wound infection or sepsis (P=0.0000), of tibio-peroneal trunk injury (P=0.003) and of a MESS score >7 (P=0.004) significantly affected secondary amputation. CONCLUSION The number of patent arteries (0-1), the presence of a MESS score >7, the incidence of tibio-peroneal trunk injury and the occurrence of postoperative deep wound infection are significant independent factors for limb loss. The presence of compartment syndrome and of ischemia time >6 hours are associated with a significantly higher risk of early reconstruction thrombosis.

Abstract
OBJECTIVE The aim of this study was to assess the clinical effectiveness of phototherapy with noncoherent light in the alleviation of chemotherapy-induced mucositis in patients with metastatic cancer. BACKGROUND DATA Mucositis occurs in more than 40% of chemotherapy-treated patients, significantly reducing the quality of their lives. Many different interventions have been evaluated to reduce oral mucositis. Recently, good results have been achieved by phototherapy with photoradiation, a technique which has virtually no side effects. Some clinical results seem to indicate that also phototherapy through noncoherent light emissions which can be produced by less expensive light sources such as light-emitting diodes (LEDs) may be effective. However, until now, no studies have been available on this subject. METHODS Twelve patients, aged from 34 to 82, selected on the basis of a diagnosis of chemotherapy-induced oral mucositis, were treated intra-orally through a noncoherent LED emission, wavelength 645 +/- 15 nm, 7.8 mW, fluence 0.99 J/cm(2), three times a day for 1 week. Mucositis was scored daily using the Daily Mucositis Index (DMI), a scale that evaluates the disease evolution through 16 different items. The primary end-point assessed was the time to recovery, from the start of LED treatment, compared to a nonrandomized control group of 12 patients with comparable stomatitis. RESULTS The median healing time, expressed as the DMI decrease, was 1.7 (range 1-2.8) and, in seven LED-treated patients, was shorter than in the control group. The healing rate (measured as the ratio of the DMIs) increased from 117% to 164%. CONCLUSION This pilot study shows that LED treatment is safe and capable of reducing the duration of chemotherapy-induced mucositis. This result needs to be confirmed in an adequate phase III study.

Abstract
The results of a serological survey for bovine herpes virus (BHV1) antibodies in the breeding cattle population of the Veneto region are presented. The data do not support the hypothesis of an high prevalence of BHV1; on farms where vaccination was not carried out most animals were seronegative, and seropositive animals were generally older. Therefore, when drawing up the guidelines for a control programme, systematic immunization (with glycoprotein E-deleted vaccines) should be restricted only to farms with a high prevalence of BHV1 antibodies and/or with a high risk of BHV1 occurrence; in most unvaccinated farms a 'test and removal' policy appears to be more appropriate in order to rapidly eradicate BHV1 from the entire stock.

Abstract
The effect of N(G)-nitro-L-arginine methyl ester (L-NAME), a competitive inhibitor of enzyme nitric oxide synthase (NOS), on spontaneous sleep during the light period, was studied in adult rats implanted for chronic sleep recordings. L-NAME was injected by subcutaneous (s.c.) or intracerebroventricular (i.c.v.) routes or was infused directly into the dorsal raphe nuclei (DRN). Subcutaneous (1.25-5.0 mg/kg) or i.c.v. (0.25-1.0 mg) administration of L-NAME increased waking (W) and reduced slow wave sleep (SWS) and rapid-eye-movement sleep (REMS) during the first 3 h of recording. On the other hand, direct application of L-NAME into the DRN (50.0-150.0 microg) induced an increment of W and a reduction of SWS without suppressing REMS. Values of W and SWS were significantly different compared with those of controls during the 6-h recording period. The effects of L-NAME observed after s.c. or i.c.v. administration confirm previous studies in rabbits and rats, in which the NOS inhibitor reduced sleep and increased W in a dose-dependent manner. It is possible that REMS suppression after L-NAME could be related to a reduction of acetylcholine release in areas critical for REMS promotion. A decrease in gamma-aminobutyric acid (GABA) release after nitric oxide synthesis inhibition could play a role in the reduction of SWS.

Abstract
Effects of the 5-HT3 receptor agonist, m-chlorophenylbiguanide (10.0-40.0 microg), on sleep and waking were studied in control, vehicle-treated and 6-hydroxydopamine-injected rats. Bilateral injections of m-chlorophenylbiguanide into the nucleus accumbens of the control and the vehicle-infused animals significantly increased waking and reduced slow wave sleep. Rapid eye movement sleep (REM sleep) remained unchanged. Pretreatment with the selective 5-HT3 receptor antagonist, MDL 72222 (1aH,3a,5a, H-tropan-3-yl-3,5-dichloro-benzoate) (0.5 mg/kg, s.c.), reversed the effects of m-chlorophenylbiguanide (10.0-20.0 microg) on sleep and waking in the control group. Administration of the 5-HT3 receptor agonist to the 6-hydroxydopamine-treated animals modified only slightly the time spent in wakefulness and slow wave sleep, while REM sleep was significantly and dose dependently reduced. Our findings further support the proposal that increase of wakefulness and reduction of slow wave sleep after activation of 5-HT3 receptors, is partly related to the release of endogenous dopamine.

Abstract
Quantitation of 2 h sessions after administration of the D3 preferring dopamine (DA) agonist pramipexole (10-500 microg/kg) showed dose-related effects on wakefulness (W), slow wave sleep (SWS) and REM sleep in rats. The 30 microg/kg dose of the DA agonist increased SWS and REM sleep and reduced W during the first recording hour, while the 500 microg/kg dose augmented W. On the other hand, W was increased while SWS and REMS were decreased after the 500 microg/kg dose during the second recording hour. The mixed D2- and D3 receptor antagonist YM-09151-2 (30-500 microg/kg), which per se affected sleep variables prevented the increase of REMS induced by pramipexole. Furthermore, the highest doses (500-1000 microg/kg) of the DA antagonist effectively antagonized the increase of W and reduction of SWS induced by the 500 microg/kg dose of the DA agonist. Pramipexole (30-100 microg/kg) induced a decrease of locomotor activity during the 2 h recording period. In addition, the 500 microg/kg dose gave rise to an initial reduction of motor behavior which was reverted 2 h later. Pramipexole (30 and 500 microg/kg) did not significantly affect striatal DA release during the first two hours following drug administration, as measured by microdialysis. It is tentatively suggested that D3 receptor could be involved in the pramipexole-induced increase of sleep and reduction of locomotor activity. On the other hand, the increase of W and of motor behavior after relatively high doses could be related to activation of postsynaptic D2 receptor.

Abstract
The present study evaluated the effects of histamine H3 receptor agonist BP 2.94 or H3 receptor antagonist carboperamide (MR 16155) given by oral route on sleep and waking in rats surgically prepared for long-term recordings. BP 2.94 produced a significant increase of slow-wave sleep (SWS) that was related to slight decreases of waking, light sleep, and REM sleep. Carboperamide significantly increased waking and decreased SWS and REM sleep. Pretreatment with carboperamide prevented the effect of BP 2.94 on SWS. It is suggested that the effects of BP 2.94 or carboperamide on sleep and waking could depend on changes in the availability of histamine at the postsynaptic H1 receptor. Alternatively, activation or blockade of the H3 heteroreceptors found in the central catecholamine, indolamine, and acetylcholine nerve endings could inhibit or increase the release of noradrenaline, serotonin, dopamine, and acetylcholine. This would secondarily result in changes of sleep variables.

Abstract
The effects of the 5-HT1B receptor agonist CP-94,253 were compared with those of the mixed beta-adrenoceptor and 5-HT1A/B receptor antagonist (+/-)pindolol in rats implanted for chronic sleep recordings. CP-94,253 (5.0-10.0 mg/kg) significantly increased waking and reduced slow wave sleep (SWS) and REM sleep (REMS). At 2.0-4.0 mg/kg (+/-)pindolol reduced REMS. Pretreatment with (+/-)pindolol (2.0-4.0 mg/kg) reversed the effect of CP-94,253 on waking and SWS, while REMS remained suppressed. It is suggested that the 5-HT1B receptor together with other 5-HT receptor subtypes may have a direct regulatory action on sleep and waking in the rat.

Pretreatment with the 5-HT3 receptor antagonist MDL 72222 (1aH,3a,5a, H-tropan-3-yl-3,5-dichloro-benzoate) (0.5 mg/kg s.c.) reversed the effects of m-chlorophenylbiguanide (10.0-20.0 micrograms) on sleep and waking. Blockade of the dopamine D1 or D2 receptor with (+)-SCH 23390 (0.25 mg/kg s.c.) or YM-09151-2 (cis-N-(1-benzyl-2-methylpyrrolidin-3-yl)-5-chloro-2-methoxy-4- methylaminobenzamide) (0.5 mg/kg s.c.), respectively antagonized the increase of waking and reduction of slow wave sleep induced by m-chloro-phenylbiguanide (10.0 micrograms). Our results tend to indicate that the increase of wakefulness after injection of the selective 5-HT3 receptor agonist m-chlorophenylbiguanide into the nucleus accumbens is partly related to the release of endogenous dopamine. In addition, they suggest that concomitant stimulation of both accumbens dopamine D1 and D2 receptor-related mechanisms is a necessary prerequisite to increase wakefulness.

Abstract
The effects of the 5-HT3 receptor agonist, m-chlorophenylbiguanide, were compared with those of the 5-HT3 receptor antagonist, MDL 72222, in rats implanted with electrodes for chronic sleep recordings. m-Chlorophenylbiguanide (12.5-50.0 micrograms) injected into the left lateral ventricle increased wakefulness and rapid eye movement (REM) sleep latency, whereas slow wave sleep, REM sleep and the number of REM periods were reduced. MDL 72222 (0.1-1.0 mg/kg, s.c.) induced a delayed and dose-dependent increase of slow wave sleep. Pretreatment with MDL 72222 (0.1-0.5 mg/kg) prevented the effects of m-chlorophenylbiguanide (50 micrograms) on wakefulness and sleep. It is suggested that the increase of wakefulness after 5-HT3 receptor activation could be related to the release of endogenous serotonin and dopamine.
