Abstract
Cisplatin is the leading chemotherapy agent for advanced liver cancer. However, the resistance to cisplatin in liver cancer reduces its efficacy. A potential strategy to increase its effectiveness and reduce toxicity is to combine cisplatin with 1,3,8-trihydroxy-6-methylanthraquinone (emodin). In this study, we examined the effects of emodin combined with cisplatin on the invasion and migration of HepG2 cells and analyzed the role of emodin. The effects of cisplatin, emodin and their combination were assessed in HepG2 cells. Proliferation, invasion and migration of HepG2 cells were examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT), scar and Transwell assays. The gelatinase spectrum and an ELISA detected the expression of matrix metallopeptidase 2 (MMP-2) and matrix metallopeptidase 9 (MMP-9). The expression of E-cadherin and vimentin was detected by immunofluorescence and Western blots. Emodin inhibited cell invasion and migration in HepG2 hepatoma cells, increased E-cadherin expression, decreased vimentin, MMP-2, and MMP-9 expression. The combination of emodin and cisplatin-induced a more significant effect in a dose-dependent manner. In this study, we found that emodin inhibited hepatocellular carcinoma (HCC) metastasis. Compared with either cisplatin or emodin alone, the combination of both showed a more significant synergistic effect. Emodin can enhance the sensitivity of HepG2 HCC cells to cisplatin by inhibiting epithelial-mesenchymal transition, and thus, play a role in preventing recurrence and metastasis in HCC.

Abstract
BACKGROUND Telemedicine is emerging as an easy way to communicate between patients and surgeons. Use of telemedicine increased during the coronavirus disease 2019 (COVID-19) pandemic. WhatsApp is one of the most common smartphone applications for user-friendly telemedicine. The aim of this study was to evaluate patient perception of health quality and positive outcomes using a diary sent by the patient to the surgeon via WhatsApp during the first post-discharge week after proctologic surgery. METHODS Ninety-eight patients discharged after proctologic surgery at the Israelite Hospital of Rome and the AOU Policlinico Umberto I of Rome in 1 January-31 December 2019 were divided into two groups: the WhatsApp group (group A), (n = 36) and the no WhatsApp group (group B) (n = 62). Group A patients received a protocol to follow for the day-by-day diary during the first post-discharge week and sending it by WhatsApp to the surgeon. Group B patients only received recommendations at discharge. The tool's usefulness was assessed by a questionnaire one month after the intervention. RESULTS The two groups were homogeneous for age, sex, schooling, employment, and proctologic pathology. Group A patients had less difficulty keeping a diary (p < 0.0001). Group A patients had the perception of better follow-up post-discharge (p = 0.002). The use of the diary sent by WhatsApp significantly improved the perception of positive post-intervention outcomes (p = 0.007). WhatsApp was the only independent predictor of perception of post-surgical positive outcomes (odds ratio = 4.06; 95% CI 1.35-12.24; p = 0.01). CONCLUSIONS The use of WhatsApp in the post-discharge period improves the lifestyle quality of the patients and their perception of the safety and quality of care received.

Abstract
Machine perfusion (MP) has been shown worldwide to offer many advantages in liver transplantation, but it still has some gray areas. The purpose of the study is to evaluate the donor risk factors of grafts, perfused with any MP, that might predict an ineffective MP setting and those would trigger post-transplant early allograft dysfunction (EAD). Data from donors of all MP-perfused grafts at six liver transplant centers have been analyzed, whether implanted or discarded after perfusion. The first endpoint was the negative events after perfusion (NegE), which is the number of grafts discarded plus those that were implanted but lost after the transplant. A risk factor analysis for NegE was performed and marginal grafts for MP were identified. Finally, the risk of EAD was analyzed, considering only implanted grafts. From 2015 to September 2019, 158 grafts were perfused with MP: 151 grafts were implanted and 7 were discarded after the MP phase because they did not reach viability criteria. Of 151, 15 grafts were lost after transplant, so the NegE group consisted of 22 donors. In univariate analysis, the donor risk index >1.7, the presence of hypertension in the medical history, static cold ischemia time, and the moderate or severe macrovesicular steatosis were the significant factors for NegE. Multivariate analysis confirmed that macrosteatosis >30% was an independent risk factor for NegE (odd ratio 5.643, p = 0.023, 95% confidence interval, 1.27–24.98). Of 151 transplanted patients, 34% experienced EAD and had worse 1- and 3-year-survival, compared with those who did not face EAD (NoEAD), 96% and 96% for EAD vs. 89% and 71% for NoEAD, respectively (p = 0.03). None of the donor/graft characteristics was associated with EAD even if the graft was moderately steatotic or fibrotic or from an aged donor. For the first time, this study shows that macrovesicular steatosis >30% might be a warning factor involved in the risk of graft loss or a cause of graft discard after the MP treatment. On the other hand, the MP seems to be useful in reducing the donor and graft weight in the development of EAD.

Abstract
BACKGROUND Transarterial chemoembolization (TACE) in patients with hepatocellular cancer (HCC) on the waiting list for liver transplantation may be associated with an increased risk for hepatic artery complications. The present study aims to assess the risk for, primarily, intraoperative technical hepatic artery problems and, secondarily, postoperative hepatic artery complications encountered in patients who received TACE before liver transplantation. METHODS Available data from HCC liver transplantation recipients across six European centres from January 2007 to December 2018 were analysed in a 1 : 1 propensity score-matched cohort (TACE versus no TACE). Incidences of intraoperative hepatic artery interventions and postoperative hepatic artery complications were compared. RESULTS Data on postoperative hepatic artery complications were available in all 876 patients (425 patients with TACE and 451 patients without TACE). Fifty-eight (6.6 per cent) patients experienced postoperative hepatic artery complications. In total 253 patients who had undergone TACE could be matched to controls. In the matched cohort TACE was not associated with a composite of hepatic artery complications (OR 1.73, 95 per cent c.i. 0.82 to 3.63, P = 0.149). Data on intraoperative hepatic artery interventions were available in 825 patients (422 patients with TACE and 403 without TACE). Intraoperative hepatic artery interventions were necessary in 69 (8.4 per cent) patients. In the matched cohort TACE was not associated with an increased incidence of intraoperative hepatic artery interventions (OR 0.94, 95 per cent c.i. 0.49 to 1.83, P = 0.870). CONCLUSION In otherwise matched patients with HCC intended for liver transplantation, TACE treatment before transplantation was not associated with higher risk of technical vascular issues or hepatic artery complications.

Abstract
The fat mass and obesity-associated (FTO) gene is one of the most important obesity susceptibility genes. Some FTO gene polymorphisms have been associated with obesity, diabetes, and hypertension, all conditions for which, after transplant, there is increased susceptibility, due to effects of immunosuppressive regimens. To evaluate whether FTO could be a candidate for targeted preventive intervention in the transplant setting, we investigated whether the common genetic variation, FTO rs9939609T>A, could affect weight gain and risk of cardiovascular complications in kidney transplantation. METHODS In 198 kidney transplant recipients, FTO rs9939609 was investigated in association with body mass index (BMI)/obesity and with other clinical markers of posttransplant risk, then monitored up to 5 years after transplantation. Genotyping was performed using an allelic discrimination method on a real-time polymerase chain (PCR) system. Associations were analyzed using the chi-square test; differences between genotypes were examined with analysis of variance or Kruskal-Wallis test; tests for repeated measures and a general linear model analysis controlling for age and gender were also utilized. RESULTS Allele and genotype frequencies of FTO rs9939609 in recipients (T/T, 29.8%; T/A, 49.0%; A/A, 21.2%; A, 45.7%; T, 54.3%) reflect those present in healthy Caucasian populations. In the face of pre-/posttransplant differences in total cholesterol, triglycerides, or fasting glucose, results did not show significant changes in these factors among genotypes either before or after transplantation. CONCLUSION This study highlights a lack of association of FTO rs9939609T>A genotypes and posttransplant weight gain, plasma lipids, and fasting blood glucose in kidney transplantation.

Abstract
BACKGROUND Arterial vascular anomalies in patients undergoing kidney transplantation (KT) are correlated with a higher incidence of early surgical complications, potentially causing graft loss. Arterial reconstruction allows patients to overcome these surgical challenges, thus minimizing the risk of poor outcomes. The aim of the present study is to retrospectively investigate the safety and effectiveness of the multiple arterial reconstruction technique with a Teflon patch in case of an unavailable aortic patch: to do so, surgical complications, graft function, and patient survival were evaluated. METHODS During the period January 2009 to August 2016, 202 adult deceased-donor KTs were performed at our center. Group A (n = 27; reconstruction of multiple arteries) and Group B (n = 175; control group) were compared. RESULTS No differences were observed between the 2 groups in terms of early postoperative course, with no vascular complication observed in Group A. No vascular patch infections were reported, nor longer cold ischemia time rates. Similarly, long-term survival rates were similar between the 2 groups. CONCLUSIONS The Teflon-patch arterial reconstruction technique appears to be safe and effective, with an acceptable balance of benefits and potential risks of using a prosthetic material. Studies based on larger series are needed to further validate this approach.

Abstract
INTRODUCTION Viral myocarditis can emerge with various symptoms, including fatal arrhythmia and cardiogenic shock, potentially evolving in chronic myocarditis or dilatative cardiomyopathy. We report a case of a kidney transplant patient affected by coxsackie viral myocarditis. METHODS A 49-year-old man was admitted to our hospital with dyspnea and fever in August 2014. He underwent living donor kidney transplantation in 1986 and polar graft resection for papillary carcinoma in 2012. RESULTS The initial investigation showed pulmonary congestion, pancreatitis, increased serum troponin I, and increased liver enzyme levels. Echocardiogram revealed an ejection fraction (EF) of 20% and PAPS 45 mm Hg. He underwent coronary stent implantation, started hemodialysis, and continued on low-dose steroid immunosuppressive therapy. The clinical course improved rapidly, but endomyocardial biopsy showed acute myocarditis. Further investigation revealed a high antibody titer against coxsackievirus B4 and B5. Pancreatic enzyme levels normalized 2 months after patient admission; his cardiac condition improved after 6 months. The patient has been followed for 1 year, and his left ventricular EF is stable (45%). CONCLUSIONS Viral myocarditis represents a serious clinical condition requiring a fast therapeutic intervention. This patient's clinical course suggests that changes in his immunosuppressive therapy were associated with progressive amelioration of his viral myocarditis.

Abstract
BACKGROUND Functional polymorphisms of molecules involved in immune-mediated mechanisms of allograft rejection could be predictive of increased risk for early and late post-transplant complications. In the past years, the challenge for long-term graft survival in kidney recipients is the implementation of personalized approaches. In this study, effects of interleukin (IL)-18-137G/C (rs187238), -607C/A (rs1946518), and other pro-inflammatory cytokine gene polymorphisms (tumor necrosis factor [TNF]-α-308G/A, rs1800629, IL-6-174G/C, rs1800795, and interferon [IFN]-γ+874A/T, rs2430561) on the main post-transplant risk parameters and diseases (metabolic, cardiovascular, infective, and chronic allograft rejection) were assessed in kidney-transplanted patients. METHODS One hundred seventy-nine transplanted patients were retrospectively analyzed for clinical and biochemical parameters and onset of post-transplant complications. Taqman allelic discrimination and PCR-SSP (polymerase chain reaction-sequence specific primers) techniques were used for genotyping. RESULTS No predictive effects of allele and genotypes of IL-18-607C/A, TNF-α-308G/A, IL-6-174G/C, and IFN-γ+874A/T gene polymorphisms and onset of risk factors and late complications were evidenced. However, Kaplan-Meier analysis evidenced a weak effect of IL-18-137G/C genotypes on graft survival. CONCLUSIONS Analyzing associations between some pro-inflammatory cytokine gene polymorphisms and onset of the most relevant risk factors and late complications of kidney transplant, results suggested a possible impact of IL-18-137G/C genotypes on graft survival, which deserves further studies.

Abstract
INTRODUCTION Immunosuppressive protocols containing everolimus (EVR) preserve good renal function in kidney transplantation (KT), although they are often complicated by several adverse events. We have evaluated the efficacy and safety of a protocol with late (1 month after KT) EVR introduction. MATERIAL AND METHODS This study randomized 49 de novo patients undergoing KT between September 2012 and June 2014 into 2 groups: group A (n = 24) with late EVR introduction and tacrolimus reduction, and group B (control group; n = 25) with a standard immunosuppressive regimen. Primary aims were 1-year patient and graft survivals and acute rejection rates. Secondary aims were related to wound, metabolic, and hematologic complications. RESULTS Patient and graft survivals were similar in both groups. One year after KT, median serum creatinine was inferior in group A (1.4 vs 1.8 mg/dL; P = .004). Late acute rejection (8.3 vs 12.0%; P = 1.0) and wound complication (4.2 vs 4.0%; P = 1.0) rates were similar. Higher cholesterol and triglycerides and lower platelets and hemoglobin levels were observed in group A. CONCLUSIONS In our experience, delayed introduction of EVR shows similar results with respect to its early introduction, contemporaneously presenting fewer wound complications and lymphoceles. A higher rate of metabolic and hematologic complications are, however, observed in patients under EVR therapy. Further multicenter studies should be performed to confirm these preliminary results.

Abstract
We examined whether erythropoietin (EPO) can inhibit adipogenic differentiation of mesenchymal stem cells (MSCs) in the mouse bone marrow and its underlying mechanism. We separated and extracted mouse bone marrow MSCs and induced adipogenic differen-tiation using 3-isobutyl-1-methylxanthine, insulin, and dexamethasone. Different concentrations of EPO were added to the cells and observed by Oil Red O staining on the 20th day to quantitatively analyze the degree of cell differentiation. mRNA expression levels of peroxysome proliferator-activated receptor γ (PPARγ), CCAAT enhancer binding protein α, and adiponectin were analyzed by real-time quantitative polymerase chain reaction, and the activity of PPARγ, extracellular sig-nal-regulated kinase (ERK), and p38 mitogen-activated protein kinase (p38 MAPK) were determined by western blotting. EPO significantly inhibited adipogenic differentiation of MSCs after 20 days and reduced absorbance values by Oil Red O staining without affecting proliferation activity. EPO downregulated the mRNA expression of PPARγ, CCAAT enhancer binding protein α, fatty acid binding protein 4, and adiponec-tin during adipogenesis and increased protein phosphorylation of ERK, p38 MAPK, and PPARγ during differentiation. EPO downregulated the mRNA expression of PPARγ, CCAAT enhancer binding protein α, fatty acid binding protein 4, and adiponectin by increasing protein phosphor-ylation of ERK, p38 MAPK, and PPARγ during differentiation, which inhibited adipogenic differentiation of MSCs.

Abstract
We analyzed predictive risk factors for recurrence of hepatocellular carcinoma (HCC) after orthotopic liver transplantation (OLT). We retrospectively analyzed the clinical data from 109 consecutive HCC patients who underwent OLT at our center from 1988 to 2007. We excluded all patients who died due to factors other than tumor recurrence within the first year (n = 24). The remaining 85 patients were enrolled in either a recurrence group (A; n = 19) or a nonrecurrence group (B; n = 66). Upon univariate analysis, the 2 groups were significantly different for 11 parameters. Group A included more females (P = .05), noncirrhotic liver recipients (P = .003), "up-to 7 status" patients (HCC with 7 as the sum of the size of the largest tumor [cm] and the number of tumors, P < .0001), patients exceeding Milan criteria (MC; P < .0001) or University of California San Francisco (UCSF) criteria (P < .0001), and OLT performed before 1999 (P = .003). Group A also showed a higher number of lesions (P = .035), a greater sum of diameters of the lesions (P < .0001), a major number of macrovascular (P < .0001) and microvascular invasions (P < .0001), and an increased number of G3-G4 grading (P = .006). Only microvascular invasion (P = .007) and exceeding UCSF criteria (P = .003) were independent risk factors for recurrence upon multivariate analysis. Patients with both these parameters are not candidates for OLT. Microvascular invasion is a good predictive parameter, but is impossible to detect preoperatively. New pre-OLT predictive risk factors are needed to achieve optimal results.

Abstract
Use of very old donors in liver transplantation (LT) is controversial because advanced donor age is associated with a higher risk for graft dysfunction and worse long-term results, especially for hepatitis C virus (HCV)-positive recipients. This was a retrospective, single-center review of primary, ABO-compatible LT performed between 2001 and 2010. Recipients were stratified in four groups based on donor age (<60 years; 60-69 years; 70-79 years and ≥80 years) and their outcomes were compared. A total of 842 patients were included: 348 (41.3%) with donors <60 years; 176 (20.9%) with donors 60-69 years; 233 (27.7%) with donors 70-79 years and 85 (10.1%) with donors ≥80 years. There was no difference across groups in terms of early (≤30 days) graft loss, and graft survival at 1 and 5 years was 90.5% and 78.6% for grafts <60 years; 88.6% and 81.3% for grafts 60-69 years; 87.6% and 75.1% for grafts 70-79 years and 84.7% and 77.1% for grafts ≥80 years (p = 0.065). In the group ≥80 years, the 5-year graft survival was lower for HCV-positive versus HCV-negative recipients (62.4% vs. 85.6%, p = 0.034). Based on our experience, grafts from donors ≥80 years may provide favorable results but require appropriate selection and allocation policies.

Abstract
BACKGROUND/AIM Milan Criteria (MC) consent excellent survivals for hepatocellular carcinoma (HCC) after liver transplantation (LT). However, several new expanded criteria were proposed, with the intent to increase the HCC patients eligible for LT, maintaining acceptable recurrence rates. The aim of the present study was to analyze a cohort of HCC patients, evaluating the evolutions in its management during the last 20 years and comparing the disease-free survivals among three different periods. METHODOLOGY HCC patients (n = 122) were transplanted and stratified in three periods: 1st (1988-1998, liberal selection), 2nd (1999-2003, use of MC) and 3rd (2004-2008, use of UCSF criteria). The three periods were analyzed and their survivals were compared. RESULTS Statistical differences were reported at univariate analysis regarding to both dimensional (total tumor diameter) and biological (alpha feto-protein, microvascular invasion) HCC features. Comparing the 5-year survival rates, a progressive increase was observed in the three periods (62.6%, 87.9% and 88.4%, respectively), with a significant difference between 1st and the second periods (p = 0.008). CONCLUSIONS In our experience, use of UCSF criteria is safe, with a contemporaneous increased number of transplants and better survivals. Introduction of new selection criteria, also based on biological features, is on the way.

Abstract
OBJECTIVES The aim of this study was to assess the long term effects of once-daily tacrolimus (OD-TAC) in a cohort of stable liver recipients converted from the twice daily tacrolimus (TD TAC), with a particular attention on the possible effects on renal function. PATIENTS AND METHODS Between September 2008 and September 2010 conversion from TD-TAC to OD-TAC was proposed in adult stable liver transplant recipients who were followed as outpatients in our Transplant centre. Conversion from TC-TAC to OD-TAC was based on a 1 mg: 1 mg proportion. Tacrolimus through levels, laboratory parameters, metabolic disorders and any adverse events were evaluated at 1, 3, 6, 12 and 24 months after conversion. Renal function was evaluated using creatinine plasma levels and estimated glomerular filtration rate (GFR) derived from the Modification of Diet in Renal Disease (MDRD). Analysis of variance and t test for paired data were utilised for the comparison of the results obtained at the scheduled controls. RESULTS Sixty-five patients were enrolled in the study (50 males, 15 females, mean age 59±8 years). Median time since liver transplant (LT) was 39 months (range: 6 to 83 months). All patients were followed for a minimum of 12 months. Ninety per cent of patients stabilized their blood levels within 45 days. Liver function, glucose and plasma lipids concentration and arterial blood pressure remained stable during the study. Renal function improved during the 24 months of follow-up. No adverse events or acute rejection episodes were recorded during the study. CONCLUSIONS Considering the advantage on patient compliance, the equivalent efficacy and the adequate safety of OD-TAC formulation may represent a useful option in liver transplant patients, with a possible advantage on renal function.

Abstract
Mirizzi syndrome (MS) represents an uncommon clinical condition, being characterized by a narrowing of the common hepatic duct or its erosion by stones impacted in the cystic duct or gallbladder Hartman's pouch. Very uncommonly, MS can be reported in patients with contemporaneous bile duct anomalies. The case is reported of a 76-year-old Caucasian woman with a MS with a cholecystobiliary fistula and a contemporaneous aberrant biliary duct for the right posterior segments.Due to the presence of an anatomical abnormality, an open approach was decided: also during surgery, it was impossible to clarify which part of the biliary tree the accessory duct merged into. After surgery, post-operative course was uneventful: the patient is alive without medical problems (follow-up: 16 months). MS represents a challenge for the surgeon. Contemporaneous presence of biliary abnormalities is anecdotic, increasing the risk of iatrogenic injuries. An open approach may be preferred in these conditions.

Abstract
Validity of living donor kidney transplantation is universally accepted. In contrast, after enthusiastic adoption in the 1990s, living donor liver transplantation has decreased in recent years. The aim of the present study was to evaluate retrospectively the current use of this form of donation in Italy by comparing liver and kidney cadaveric and living donations from 2002 to 2010. The number of liver transplantations from living donors has decreased from 34 in 2002 (3.9% of total) to 13 in 2010 (1.3% of total). In contrast, kidney transplantation from living donors increased from 126 (7.9% of total) to 186 (11% of total). We observed that living donations for kidney transplantation are still underused, especially with unrelated donors. Living donor liver transplantation has decreased in recent years; this procedure should be reserved to centers with particular expertise. It would be appropriate to implement programs to increase the attention of health professionals and the general population and to integrate living donations into programs of deceased organ donation.

Abstract
Only patients with Model for End-stage Liver Disease (MELD) scores ≥18 or ≥17 experience a survival benefit (SB) at 12 and 36 months after liver transplantation (OLT). The SB calculation estimates the difference after stratification for risk categories between the survival rate of transplanted versus waiting list patients. The aim of this study was to perform a short- and long-term (60 months) SB analyses of a Italian OLT program. One-hundred seventy-one patients were stratified into four MELD classes (6-14, 15-18, 19-25, 26-40), and two groups: namely, waiting list (WL) and transplanted groups (TX). The median waiting time for transplanted patients was 4.4 months (range, 0-35). SB was expressed as mortality hazard ratio (MHR) as obtained through a Cox regression analysis using as a covariate the status of each patient in the waiting list (WL = 0, reference group) or the TX group (TX = 1). Values over 1 indicated the MHR in favor of the WL with the values below 1 indicating MHR in favor of Tx. In the MELD class 6 to 14, the MHR was above 1 at 3 and 6 months, indicating an SB in favor of WL; subsequently, the MHR dropped below 1, indicating an SB in favor of TX (P < .05). In the MELD class 15 to 18 the MHR was above 1 at 3 months, but below 1 subsequently (P < .05). For MELD classes 19 to 25 and 26 to 40, the MHR was always below 1 (P < .01). According to the SB approach, patients in the MELD class 6 to 14 could safely wait for at least 36 months; patients in the MELD class 15 to 18 should likely remain no longer than 12 months on the waiting list, and all the remaining patients with MELD > 18 should be transplanted as soon as possible. OLT should not be precluded but only postponed for MELD < 19 patients.

Abstract
Hepatic resection for giant haemangioma in a patient with a contemporaneous adult polycystic liver disease. According to Gigot classification, and to the characteristics of haemangioma surgery in these patients can be considered safe. We report the case of a 55 year-old man affected by an adult polycystic liver disease (PCLD) and a contemporaneous symptomatic haemangioma of the III segment. At the preoperative imaging scans, APCLD was classified in a type II grading according to Gigot classification. The patient underwent surgery: a wedge resection of the III segment with the exportation of the haemangioma and a fenestration of a large cyst placed in the VIII segment were performed. Post-operative course was regular and the patient was discharged uneventfully in post-operative 9th day, with a total regress of the initial symptoms. APCLD and haemangioma are two benign conditions that do not require surgery except if they cause important symptoms, such as pain. The good clinical conditions of the patient, the moderate gravity of the APCLD and the particular exofitic localisation of the cavernous haemangioma gave us the possibility to make a safe surgery for the patient. To the best of our knowledge, this is the first case reported in literature in which a liver resection for haemangioma in patient with APCLD was performed. In conclusion, liver resection for haemangioma is not contraindicated, mainly if it is symptomatic, even in the contemporaneous presence of an APCLD.

Abstract
Neuroendocrine tumours of the colon and rectum are infrequent. Clinical manifestations are not different from standard adenocarcinoma. Symptoms are non specific; the most common are abdominal pain, nausea and vomiting, weight loss and gastrointestinal blood loss. We report an advanced case of transverse colon neuroendocrine carcinoma with multiple metastasis. When these tumours are diagnosed, they have distance disease related to a poor prognosis for the patient. Surgery is the treatment that can offer a greater chance of survival to these patients.

Abstract
Abstract
Introduction Translational breast cancer research is hampered severely by difficulties in obtaining and studying primary human breast tissue, and by the lack of in vivo preclinical models that accurately reflect patient tumor biology. These limitations are due, in part, to the fact that traditional immunocompromised mouse models are not generally permissive for growth. We sought to circumvent some of these limitations by transplanting and growing human mammary tumors in the mammary fat pad of SCID/Beige immunocompromised mice in the absence of exogenous human fibroblasts.
Aims and Methods To establish a set of stable human breast cancer xenografts for preclinical studies. Human breast cancer biopsies were received, minced into small fragments and then transplanted directly into “cleared” fat pads of recipient SCID/Beige immunocompromised mice. Transplanted fat pads were checked weekly. After initial tumor was palpated and harvested, tumor fragments were transplanted into new SCID/Beige hosts for subsequent transplant generations. Serial immunohistochemical evaluations were performed to confirm human origin and biomarker status. Analytical flow cytometry for evaluating expression of proposed “cancer stem cell” markers, and gene and protein expression analysis were carried out on all stable lines.
Results and Conclusions Xenograft lines were established directly from breast cancer patient samples, without intervening culture in vitro, using the epithelium-free mammary fat pad as the transplantation site. Of the conditions tested, xenograft take rate was highest in the presence of a low-dose estradiol pellet without exogenous human fibroblasts. Thirty six stably transplantable xenograft lines representing 27 patients were established, using pre-treatment, mid-treatment, and/or post-treatment samples. Most patients yielding xenografts were “triple-negative” (ER-PR-HER2−) (n=21), we were able to establish lines from three ER-PR-HER2+ patients, one ER+PR+HER2−, one ER+PR-HER2−and one “triple-positive” (ER+PR+HER2+) patients. Serially passaged xenografts show phenotypic consistency with the tumor of origin at the histopathology level, and remarkable stability across multiple transplant generations at both the genomic, transcriptomic, and proteomic levels. Of 27 lines evaluated fully, thirteen xenografts showed metastasis to the mouse lung. These models thus serve as a renewable, quality-controlled tissue resource, and should prove useful for preclinical evaluation of experimental therapeutics.

Abstract
Abstract
Background: Systemic therapies are effective initially in controlling and reversing tumor growth; however, residual cancers will invariably re-grow despite this initial response. We have published data from paired human breast cancer samples that standard therapy every three weeks kills dividing daughter cells but not tumor-initiating cells (TICs), so that samples obtained after therapy are enriched for CD44+/CD24−/low putative “tumor-initiating” or “cancer stem” cells, indicating that standard treatment regimens are missing the critical targets, TICs. Interestingly, we have recent data in human breast tumors that indicate that TICs may in fact be chemosensitive initially, with a decrease in TICs observed within two days of chemotherapy, but shortly thereafter, TICS are actually induced by chemotherapy.
Materials and Methods: To evaluate TICs response to chemotherapy, mice with human breast tumor xenograft lines BCM-2665a and BCM-2147 were treated with vehicle, 10-, or 33-mg/kg docetaxel, and then tumors were collected for TIC assays and molecular analysis at both 48 and 72h after treatment. Using Affymetrix gene expression microarrays and reverse phase protein array (RPPA) analysis with 119 different validated antibodies, we identified pathways involved in regulation of TICs. Results: According to flow cytometric analysis for TIC markers and mammosphere (MS) formation efficiency, BCM-2665 TICs were reduced by docetaxel treatment compared to vehicle-treated at 48h post 10 mg/kg docetaxel (4-fold decrease) and 48 and 72h post 33 mg/kg docetaxel compared to control (14- and 2-fold decrease, respectively). Although the BCM-2147 TICs did not significantly decrease at any time points or doses tested, they were clearly induced at 72h post-treatment compared to control. Additionally, BCM-2665 TICs were increased within 72h post 10 mg/kg docetaxel, indicating that these time points are ideal for defining the mechanisms responsible for induction of TICs. Ingenuity Pathway Analysis of Affymetrix microarray data for both BCM-2665 and BCM-2147 revealed induction of inflammatory pathways, suggesting leukocyte infiltration associated with induction of TICs. Furthermore, RPPA analysis confirmed gene expression changes from the microarray data, and implicated apoptosis and inflammatory pathways. Sixteen of 28 proteins significantly changed with activation of CSC are involved in development of leukocytes. Discussion: These findings are consistent with the Norton-Simon Hypothesis in that chemotherapy regimens given more frequently may in fact eliminate TICs, thereby explaining the proven increased effectiveness of dose-dense chemotherapy. Based on when TICs became chemoresistant, we are comparing dose-dense treatment (4 mg/kg docetaxel every 3 days) to a traditional single dose of 32 mg/kg, in an effort to eliminate the tumor cells that cause tumor recurrence. Furthermore, our analysis of gene expression at both the RNA and protein level implicated the immune cells as TICs inducers. Since our immunocompromised mice lack T- and B- cells but have active macrophages, macrophages are indicated as inducers of TICs. We are focusing our current efforts at identifying how immune cells activate TICs and thus enhance tumorigenesis.

Abstract
BACKGROUND In the past decades, the inferior vena cava (IVC) reconstruction technique has undergone several evolutions, such as biopump, piggyback technique (PB), and laterolateral approach (LLPB). Several advantages are reported comparing the PB technique to biopump use. However, comparison between PB and LLPB has not been as well investigated. The aim of this study was to compare the results in terms of immediate graft function and intermediate graft survival among 3 subgroups characterized by distinct caval reconstruction techniques. METHODS We retrospectively analyzed a cohort of 200 consecutive adult patients who underwent liver transplantation from January 2001 to December 2009. The patients were stratified according to 3 caval reconstructive techniques: biopump (n=135), PB (n=32) and LLPB (n=33). RESULTS The LLPB group showed the shortest cold and warm ischemia times and the best immediate postoperative graft function. Survival analysis revealed LLPB patients to present the best 1-year graft survival rates: namely, 90.9% versus 75.0% and 74.1% among the PB and biopump groups, respectively (log-rank tests: LLPB vs biopump: P=.03; LLPB vs PB: P=.05). In our experience, LLPB showed the best graft survivals with an evident reduction in both cold and warm ischemia times. However, it is hard to obtain an irrefutable conclusion owing to the retrospective nature of this study, the small sample, and the different periods in which the groups were transplanted. CONCLUSIONS LLPB technique was a safe procedure that minimized the sequelal of ischemia-reperfusion damage. This technique yielded results superior to venovenous bypass. No definitive conclusions can to be obtained in this study comparing classic PB or LLPB.

Abstract
Numerous evidence has been reported to support a safe 1:1 conversion from the twice-daily tacrolimus (Tac-T) to the once-daily tacrolimus regimen (Tac-O), but frequently there is a reduction in drug trough levels, which has been estimated by some authors to be about 20%. The relationship between Tac-O dosage and trough levels after conversion is not clear. The tacrolimus trough levels-to-dose ratio has been applied to better define the wide variability in doses and blood levels of tacrolimus. The aim of this study was to evaluate tacrolimus trough levels, tacrolimus daily dosage, and tacrolimus level-to-dose ratio during 1 year pre-postconversion follow-up in 31 stable kidney transplant patients who had received Tac-T therapy for over 6 months with stable renal function. They were converted to the same dosage of Tac-O. Patients before and after conversion were their own controls. The trough levels of tacrolimus showed a slight albeit significant reduction after conversion, remaining in the therapeutic range. Nineteen percent underwent an adjustment in total daily dosage after conversion versus 39% before conversion with no significant difference. No significant differences were detected in the total daily dose administered either by tacrolimus level-to-dose ratio before or after conversion. Kidney transplant recipients under Tac-O therapy were safely maintained using the same therapeutic monitoring as when receiving Tac-T.

Abstract
The concurrent detection of hepatitis B e antigen (HBeAg) and its corresponding antibody (anti-HBe) in patients with chronic hepatitis B virus (HBV) infection is well established but the clinical features remain poorly understood. Demographic information, clinical and laboratory data were collected from 1624 consecutive inpatient records of patients with chronic hepatitis B. Viral genotype, basic core promoter and precore mutations were determined by direct sequencing. In vitro HBeAg and anti-HBe binding experiments were conducted with three pairs of HBeAg-positive and anti-HBe-positive serum samples, which were mixed at variable ratios and incubated at 37°C for 3-24h. Of the 1624 chronic patients, 169 (10.4%) had concurrent HBeAg and anti-HBe positivity, and this was associated with intermediate age and HBV-DNA load, higher alanine aminotransferase level and more pronounced liver damage compared with HBeAg-positive or anti-HBe-positive patients alone. HBeAg and anti-HBe titres (median and interquartile range, S/CO) in the concurrent positive group were 4.2 (1.8-9.6) and 0.54 (0.27-0.72), which were closer to their respective cut-off values than those of HBeAg-positive or anti-HBe-positive groups alone. For the cases successfully sequenced, 110/134 (82.1%) harboured T1762/A1764 or/and A1896 mutants. The binding experiments showed that HBeAg and anti-HBe could be concurrently observed provided an optimal ratio (HBeAg to anti-HBe) was chosen. In antiviral treatment-naive patients, concurrence of HBeAg and anti-HBe was not uncommon, and such patients had profound liver disease. An optimal ratio between HBeAg and anti-HBe led to their concurrent detection when sera were tested by sensitive assays.

Abstract
We report a rare case of a hepatic carcinosarcoma with rabdomyosarcomatous differentiation in its sarcomatous component. A 71-year old Caucasian female patient underwent a liver resection for a 4-cm lesion developed on an underlying HCV-related cirrhosis. Post-operative course was uneventful and the patient was discharged 5 days after surgery. At pathology, the tumor presented the features of hepatocellular carcinoma and rhabdomyosarcoma Three months later the patient experienced a liver recurrence, dying 2 months later for systemic disease. The reported case presents several peculiarities, i.e. the female gender, the HCV-related cirrhotic status, and the European origin of the patient. However, the outcome of our case confirms that this neoplasm pursues a highly aggressive course with poor prognosis.

Abstract
INTRODUCTION The current shortage of organs for liver transplantation (OLT) requires expansion of the donor pools. A possible approach to this problem may be the use of donors positive for antibody against hepatitis B core antigen (anti-HBc). However, it is not clear whether recipients who receive anti-HBc-positive livers show worse survival. The aim of this study was to retrospectively analyze the patient and graft survivals of two groups of OLT recipients according to the anti-HBc status of their respective donors. METHODS We stratified 133 patients into group 1 (n = 120; anti-core-negative donors) versus group 2 (n = 13; anti-core-positive donors). RESULTS Comparing the two groups by univariate analysis, there was no significant differences with regard to recipient, donor, or transplant characteristics. Group 2 showed worse 5-year patient (46.2% vs 72.0%; P = .006) and graft survivals (38.5% vs 68.4%; P = .003). After adjustment for several risk factors for post-OLT death and graft failure, there was no significant difference between patients who received anti-core-positive versus anti-core-negative donors, in terms of patient and graft survivals, particularly only after adjustment for Model for End-stage Liver Disease (MELD) degree of severity. CONCLUSION The use of anti-HBc-positive donors resulted in worse post-OLT patient and graft survival rates. Unlike the results obtained in the United States, we did not find possible confounders in our results, excluding MELD ≥ 20. However, due to the small size of our cohort, future prospective multicenter studies are required to clarify the safety of anti-core-positive grafts.

Two homogenous groups were studied: one treated with standard medical therapy (SMT) and the other, with MARS. MATERIALS AND METHODS Twenty acute-on-chronic liver failure patients on the waiting list for liver transplantation and affected by alcoholic cirrhosis with similar MELD scores (20-29) were evaluated for 7 days from inclusion and for 6-month survival. Ten patients (seven males and three females) were treated with MARS. Their mean age was 48.5 years (range = 35-61). The number of MARS applications was six for 6 consecutive days, and the length of the applications was 8 hours. Ten other patients (seven males and three females) were treated with SMT, including prophylaxis against bacterial infections and judicious use of diuretics. The precipitating factors were also treated appropriately. The mean age of the patients was 51 years (range = 37-64). All the variables that were significant upon univariate analysis were enrolled in a receiver operating characteristic analysis, with the intention to detect predictive parameters for patient death at 6 months. We considered a significant area under curve (AUC) value to be greater than 0.5. RESULTS Among 11 patients who died within 6 months there were in the MARS group and eight in the SMT group: the 3- and 6-month patient survival rates were 90% and 70% versus 30% and 20% in the two groups, respectively. Nine measures resulted in an AUC > 0.5: DeltaMELD; interleukin (IL)-8; IL-6; tumor necrosis factor- alpha, MELD score; creatinine, bilirubin international normalized ratio (INR) and cardiac index. DeltaMELD and postoperative IL-8 concentrations showed better results (AUC = 0.899), followed by postoperative creatinine (AUC = 0.879), postoperative cardiac index (AUC = 0.833), and postoperative INR (AUC = 0.818). Postoperative creatinine showed the best sensitivity (100%), while IL-8, the best specificity (88.9%). CONCLUSION A combination of biochemical and clinical variables probably represent the best way to predict the survival of patients, allowing physicians to select the best therapies for each patient.

Abstract
Abstract
In translational breast cancer research, our ability to evaluate clinical responses of human tumors to new therapeutic agents is severely limited experimentally. For example, it is not possible to evaluate the response of a single tumor to multiple candidate therapeutic agents. Conversely, the limited number of well-characterized in vivo preclinical human tumor models currently available precludes evaluation of multiple clinically relevant tumors with candidate therapeutic agents. These limitations severely impinge on our ability to develop and test novel therapeutic agents, particularly those that may target tumor-initiating “cancer stem cells”, which are relatively resistant to chemotherapy and radiation and may be responsible for disease recurrence and metastases.Historically, in vivo experimental therapeutic research has relied on either genetically engineered animal models, or “xenograft” transplantation models in which established human cancer cell lines are transplanted into immunocompromised host mice. However, each type of model has significant limitations. We sought to circumvent some of these limitations by propagating a cohort of human tumors as stably transplantable xenograft tissue lines grown in the absence of engineered or immortalized fibroblasts by transplanting clinical biopsies directly into the mammary fat pad of SCID/Beige immunocompromised mice (lacking B-cell, T-cell, and NK cell function) without intervening culture in vitro.Thus far, we have established 13 independent stably transplantable xenograft lines representing nine “triple-negative” (ER-PR-HER2-), two HER2+, and two ER+ breast cancers. Established xenograft lines show phenotypic similarity to the primary tumor with respect to histology and gene expression. Xenografts are being characterized genetically by whole genome sequencing as well as for the diversity of tumor-initiating cell types present. These models are proving useful for the evaluation of experimental therapeutics for their ability to inhibit tumor growth, and for their ability to target the subset cancer cells capable of regenerating tumors upon transplantation, with the goals of overcoming chemoresistance, preventing disease recurrence, and eliminating metastases.

Abstract
Analysis of the anti-HLA antibody status of 100 recipients of kidneys from deceased donors demonstrated that presensitization and the development of alloantibodies after transplantation are associated with the development of antibody mediated as well as cellular rejection. This finding indicates that the humoral arm of the immune response is also involved in cell-mediated rejection and/or that there may be a continuum between these two forms of rejection. Most episodes of rejection were successfully reversed in our population, as shown by the overall 3-year actuarial survival of 98% in nonsensitized and 91% in sensitized recipients, emphasizing the importance of comprehensive antibody studies.
