Abstract
The utilization of kidneys from donors with acute kidney injury (AKI) is often limited by unpredictable post-transplantation outcomes. The aim of our study was to identify protein mediators implicated in either recovery or failure of these organs. Forty kidney biopsies from donors with (20) and without AKI (20) were selected and then subdivided according to the post-transplant outcome defined as a threshold of 45 ml/min for the eGFR at 1 year from transplantation. Tissue homogenates were analysed by western blot to assess how the levels of 17 pre-selected proteins varied across the four groups. Samples from AKI kidneys with a poor outcome showed a fourfold increase in the levels of PPARg and twofold reduction of STAT1 compared to the other groups (p < 0.05). On the contrary, antioxidant enzymes including TRX1 and PRX3 were increased in the AKI kidneys with a good outcome (p < 0.05). An opposite trend was observed for the detoxifying enzyme GSTp which was significantly increased in the AKI group with poor versus good outcome (p < 0.05). The importance of lipid metabolism (PPARg) and inflammatory signals (STAT1) in the function recovery of these kidneys hints to the therapeutical targeting of the involved pathways in the setting of organ reconditioning.

Abstract
Prevention of infections is crucial in solid organ transplant (SOT) candidates and recipients. These patients are exposed to an increased infectious risk due to previous organ insufficiency and to pharmacologic immunosuppression. Besides infectious-related morbidity and mortality, this vulnerable group of patients is also exposed to the risk of acute decompensation and organ rejection or failure in the pre- and post-transplant period, respectively, since antimicrobial treatments are less effective than in the immunocompetent patients. Vaccination represents a major preventive measure against specific infectious risks in this population but as responses to vaccines are reduced, especially in the early post-transplant period or after treatment for rejection, an optimal vaccination status should be obtained prior to transplantation whenever possible. This review reports the currently available data on the indications and protocols of vaccination in SOT adult candidates and recipients.

Abstract
Renal normothermic machine perfusion (NMP) is an organ preservation method based on the circulation of a warm (35-37 °C) perfusion solution through the renal vasculature to deliver oxygen and nutrients. However, its biological effects on marginal kidneys are unclear. We therefore used mass spectrometry to determine the proteomic profile of kidney tissue and urine from eight organs reconditioned for 120 min using a Kidney Assist device. Biopsies were taken during the pre-implantation histological evaluation (T-1), at the start of back table preparation (T0), and after 60 and 120 min of perfusion (T60, T120). Urine samples were collected at T0 (urine produced in the first 15 min after the beginning of normothermic reperfusion), T30, T60 and T120. Multiple algorithms, support vector machine learning and partial least squares discriminant analysis were used to select the most discriminative proteins during NMP. Statistical analysis revealed the upregulation of 169 proteins and the downregulation of 196 during NMP. Machine learning algorithms identified the top 50 most discriminative proteins, five of which were concomitantly upregulated (LXN, ETFB, NUDT3, CYCS and UQCRC1) and six downregulated (CFHR3, C1S, CFI, KNG1, SERPINC1 and F9) in the kidney and urine after NMP. Latexin (LXN), an endogenous carboxypeptidase inhibitor, resulted the most-upregulated protein at T120, and this result was confirmed by ELISA. In addition, functional analysis revealed that the most strongly upregulated proteins were involved in the oxidative phosphorylation system and ATP synthesis, whereas the downregulated proteins represented the complement system and coagulation cascade. Our proteomic analysis demonstrated that even brief periods of NMP induce remarkable metabolic and biochemical changes in marginal organs, which supports the use of this promising technique in the clinic.

Abstract
Surgical strategies for graft portal vein flow restoration vary from termino-terminal portal vein anastomosis to more complex bypass reconstructions. Although the surgical strategy strongly influences the post-operative outcome, the Yerdel grading is still commonly used to determine the prognosis of patients with portal vein thrombosis (PVT) undergoing liver transplantation (LT). We retrospectively reviewed the cases of LT performed on recipients with complex PVT at two high-volume transplantation centres. We stratified the patients by the type of portal vein reconstruction, termino-terminal portal vein anastomosis (TTA) versus bypass reconstruction (bypass group), and assessed a multivariable survival analysis. The rate of mortality at 90 days was 21.4% for the bypass group compared to 9.8% in the TTA group (p = 0.05). In the multivariable correlation analysis, only a trend for greater risk of early mortality was confirmed in the bypass groups (HR 2.5; p = 0.059). Yerdel grade was uninfluential in the rate of early complications. A wide range of surgical options are available for different situations of PVT which yield an outcome unrelated to the Yerdel grading. An algorithm for PVT management should be based on the technical approach and should include a surgically oriented definition of PVT extension.

Abstract
Reno-portal anastomosis (RPA) in presence of spleno-renal shunts (SRS) is a physiological option to restore blood flow in liver transplantation with portal vein thrombosis (PVT). Diffuse splanchnic venous system thrombosis (complex PVT) is its main indication but RPA proved to be useful in selected cases of less extensive thrombosis (non-complex PVT). Up until now only two monocentric and one multicentric case series has been published on this topic in addition to few anecdotal reports. After 2014, we introduced RPA in our institution to manage some cases of complex PVT in presence of SRS. Here, we present the evolution of indication to RPA. From 2014 to 2020, we performed ten RPA: nine patients presented non-complex and one complex PVT. Overall early and late complication rates were 66.6% and 50%, respectively. Two patients developed RPA stenosis, treated by interventional radiology. Self-resolving acute kidney injury (AKI) was observed in three cases. No re-transplantation was necessary. RPA was patent in all patients, with a mean follow-up of 41.9 months. The overall patient survival was 70% at 1 year and 60% at 3 and 5 years. Four patients died at 1, 2, 3 and 20 months from LT. Causes of deaths were, respectively, stroke, cerebral infection, sepsis (MOF) and sudden variceal bleeding in sinusoidal obstruction syndrome. The relative simplicity and effectiveness of RPA in presence of SRS allowed us to rely more and more often on this technique in liver transplantation with challenging non-complex PVT.

Abstract
The biological age of an organ may represent a valuable tool for assessing its quality, especially in the elder. We examined the biological age of the kidneys [right (RK) and left kidney (LK)] and blood leukocytes in the same subject and compared these to assess whether blood mirrors kidney biological aging. Biological age was studied in n = 36 donors (median age: 72 years, range: 19-92; male: 42%) by exploring mitotic and non-mitotic pathways, using telomere length (TL) and age-methylation changes (DNAmAge) and its acceleration (AgeAcc). RK and LK DNAmAge are older than blood DNAmAge (RK vs. Blood, p = 0.0271 and LK vs. Blood, p = 0.0245) and RK and LK AgeAcc present higher score (this mean the AgeAcc is faster) than that of blood leukocytes (p = 0.0271 and p = 0.0245) in the same donor. TL of RK and LK are instead longer than that of blood (p = 0.0011 and p = 0.0098) and the increase in Remuzzi-Karpinski score is strongly correlated with kidney TL attrition (p = 0.0046). Finally, blood and kidney TL (p < 0.01) and DNAmAge (p < 0.001) were correlated. These markers can be evaluated in further studies as indicators of biological age of donor organ quality and increase the usage of organs from donors of advanced age therefore offering a potential translational research inkidney transplantation.

Abstract
Background Although kidney transplantation improves patient survival and quality of life, long-term results are hampered by both immune- and non-immune-mediated complications. Current biomarkers of post-transplant complications, such as allograft rejection, chronic renal allograft dysfunction, and cutaneous squamous cell carcinoma, have a suboptimal predictive value. DNA methylation is an epigenetic modification that directly affects gene expression and plays an important role in processes such as ischemia/reperfusion injury, fibrosis, and alloreactive immune response. Novel techniques can quickly assess the DNA methylation status of multiple loci in different cell types, allowing a deep and interesting study of cells’ activity and function. Therefore, DNA methylation has the potential to become an important biomarker for prediction and monitoring in kidney transplantation.
Purpose of the study The aim of this study was to evaluate the role of DNA methylation as a potential biomarker of graft survival and complications development in kidney transplantation. Material and Methods A systematic review of several databases has been conducted. The Newcastle–Ottawa scale and the Jadad scale have been used to assess the risk of bias for observational and randomized studies, respectively.
Results Twenty articles reporting on DNA methylation as a biomarker for kidney transplantation were included, all using DNA methylation for prediction and monitoring. DNA methylation pattern alterations in cells isolated from different tissues, such as kidney biopsies, urine, and blood, have been associated with ischemia–reperfusion injury and chronic renal allograft dysfunction. These alterations occurred in different and specific loci. DNA methylation status has also proved to be important for immune response modulation, having a crucial role in regulatory T cell definition and activity. Research also focused on a better understanding of the role of this epigenetic modification assessment for regulatory T cells isolation and expansion for future tolerance induction-oriented therapies. Conclusions Studies included in this review are heterogeneous in study design, biological samples, and outcome. More coordinated investigations are needed to affirm DNA methylation as a clinically relevant biomarker important for prevention, monitoring, and intervention.

Abstract
Background The impact of sugammadex in patients with end-stage renal disease undergoing kidney transplantation is still far from being defined. The aim of the study is to compare sugammadex to neostigmine for reversal of rocuronium- and cisatracurium-induced neuromuscular block (NMB), respectively, in patients undergoing kidney transplantation. Methods A single-center, 2014-2017 retrospective cohort case-control study was performed. A total of 350 patients undergoing kidney transplantation, equally divided between a sugammadex group (175 patients) and a neostigmine group (175 patients), were considered. Postoperative kidney function, evaluated by monitoring of serum creatinine and urea and estimated glomerular filtration rate (eGFR), was the endpoint. Other endpoints were anesthetic and surgical times, post-anesthesia care unit length of stay, postoperative intensive care unit admission, and recurrent NMB or complications. Results No significant differences in patient or, with the exception of drugs involved in NMB management, anesthetic, and surgical characteristics, were observed between the two groups. Serum creatinine (median [interquartile range]: 596.0 [478.0-749.0] vs 639.0 [527.7-870.0] μmol/L, p = 0.0128) and serum urea (14.9 [10.8-21.6] vs 17.1 [13.1-22.0] mmol/L, p = 0.0486) were lower, while eGFR (8.0 [6.0-11.0] vs 8.0 [6.0-10.0], p = 0.0473) was higher in the sugammadex group than in the neostigmine group after surgery. The sugammadex group showed significantly lower incidence of postoperative severe hypoxemia (0.6% vs 6.3%, p = 0.006), shorter PACU stay (70 [60-90] min vs 90 [60-105] min, p < 0.001), and reduced ICU admissions (0.6% vs 8.0%, p = 0.001). Conclusions Compared to cisatracurium-neostigmine, the rocuronium-sugammadex strategy for reversal of NMB showed a better recovery profile in patients undergoing kidney transplantation.

Abstract
Background: In the setting of kidney transplantation, histopathology of kidney biopsies is a key element in the organ assessment and allocation. Despite the broad diffusion of the Remuzzi–Karpinski score on preimplantation kidney biopsies, scientific evidence of its correlation to the transplantation outcome is controversial. The main issues affecting the prognostic value of histopathology are the referral to general on-call pathologists and the semiquantitative feature of the score, which can raise issues of interpretation. Digital pathology has shown very reliable and effective in the oncological diagnosis and treatment; however, the spread of such technologies is lagging behind in the field of transplantation. The aim of our study was to create a digital online platform where whole-slide images (WSI) of preimplantation kidney biopsies could be uploaded and stored. Methods: We included 210 kidney biopsies collected between January 2015 and December 2019 from the joint collaboration of the transplantation centers of Padua and Verona. The selected slides, stained with hematoxylin and eosin, were digitized and uploaded on a shared web platform. For each case, the on-call pathologists' Remuzzi grades were obtained from the original report, together with the clinical data and the posttransplantation follow-up. Results: The storage of WSI of preimplantation kidney biopsies would have several clinical, scientific, and educational advantages. The clinical utility relies on the possibility to consult online expert pathologists and real-time quality checks of diagnosis. From the perspective of follow-up, the archived digitized biopsies can offer a useful comparison to posttransplantation biopsies. In addition, the digital online platform is a precious tool for multidisciplinary meetings aimed both at the clinical discussion and at the design of research projects. Furthermore, this archive of readily available WSI is an important educational resource for the training of professionals. Conclusions: Finally, the web platform lays the foundation for the introduction of artificial intelligence in the field of transplantation that would help create new diagnostic algorithms and tools with the final aim of increasing the precision of organ assessment and its predictive value for transplant outcome.

Abstract
The First World Consensus Conference on Pancreas Transplantation provided 49 jury deliberations regarding the impact of pancreas transplantation on the treatment of diabetic patients, and 110 experts' recommendations for the practice of pancreas transplantation. The main message from this consensus conference is that both simultaneous pancreas-kidney transplantation (SPK) and pancreas transplantation alone can improve long-term patient survival, and all types of pancreas transplantation dramatically improve the quality of life of recipients. Pancreas transplantation may also improve the course of chronic complications of diabetes, depending on their severity. Therefore, the advantages of pancreas transplantation appear to clearly surpass potential disadvantages. Pancreas after kidney transplantation increases the risk of mortality only in the early period after transplantation, but is associated with improved life expectancy thereafter. Additionally, preemptive SPK, when compared to SPK performed in patients undergoing dialysis, appears to be associated with improved outcomes. Time on dialysis has negative prognostic implications in SPK recipients. Increased long-term survival, improvement in the course of diabetic complications, and amelioration of quality of life justify preferential allocation of kidney grafts to SPK recipients.

Abstract
The complement system plays a pivotal role in the pathogenesis of ischemia-reperfusion injury in solid organ transplantation. Mirococept is a potent membrane-localizing complement inhibitor that can be administered ex vivo to the donor kidney prior to transplantation. To evaluate the efficacy of Mirococept in reducing delayed graft function (DGF) in deceased donor renal transplantation, we undertook the efficacy of mirococept (APT070) for preventing ischaemia-reperfusion injury in the kidney allograft (EMPIRIKAL) trial (ISRCTN49958194). A dose range of 5-25 mg would be tested, starting with 10 mg in cohort 1. No significant difference between Mirococept at 10 mg and control was detected; hence the study was stopped to enable a further dose saturation study in a porcine kidney model. The optimal dose of Mirococept in pig kidney was 80 mg. This dose did not induce any additional histological damage compared to controls or after a subsequent 3 hours of normothermic machine perfusion. The amount of unbound Mirococept postperfusion was found to be within the systemic dose range considered safe in the Phase I trial. The ex vivo administration of Mirococept is a safe and feasible approach to treat DGF in deceased donor kidney transplantation. The porcine kidney study identified an optimal dose of 80 mg (equivalent to 120 mg in human kidney) that provides a basis for further clinical development.

Abstract
PURPOSE Kidney transplantation is the gold-standard treatment for end stage renal disease. Although different hemodynamic variables, like central venous pressure and mean arterial pressure, have been used to guide volume replacement during surgery, the best strategy still ought to be determined. Respiratory arterial Pulse Pressure Variation (PPV) is recognized to be a good predictor of fluid responsiveness for perioperative hemodynamic optimization in operating room settings. The aim of this study was to investigate whether a PPV-guided fluid management strategy is better than a liberal fluid strategy during kidney transplantation surgeries. Identification of differences in urine output in the first postoperative hour was the main objective of this study. METHODS We conducted a prospective, single blind, randomized controlled trial. We enrolled 40 patients who underwent kidney transplantation from deceased donors. Patients randomized in the PPV Group received fluids whenever PPV was higher than 12%, patients in the Free Fluid Group received fluids following our institutional standard care protocol for kidney transplantations (10mL.kg-1.h-1). RESULTS Urinary output was similar at every time-point between the two groups, urea was statistically different from the third postoperative day with a peak at the fourth postoperative day and creatinine showed a similar trend, being statistically different from the second postoperative day. Urea, creatinine and urine output were not different at the hospital discharge. CONCLUSION PPV-guided fluid therapy during kidney transplantation significantly improves urea and creatinine levels in the first week after kidney transplantation surgery.

Abstract
No data are available on rivaroxaban use in renal transplant recipients and on its surmised interaction with immunosuppressants. The aim was to investigate potential interactions between rivaroxaban and immunosuppressants in this setting. Renal transplant recipients with a stable renal function treated with rivaroxaban and tacrolimus with or without everolimus were investigated. All drugs and creatinine concentrations were determined daily for 2 weeks after the start of anticoagulation. Blood samples were drawn at 8.00 am and 3-4 h later for trough and peak concentrations, respectively. Bleeding and thrombotic events were recorded during a minimum follow-up of 6 months. In 8 renal transplant patients, rivaroxaban levels showed a predictable pharmacokinetic trend, both at Ctrough (30-61 μg/L) and at Cpeak (143-449 μg/L), with limited variability in the 25th-75th percentile range. Tacrolimus (Ctrough 3-13 μg/L; Cpeak 3-16 μg/L), everolimus (Ctrough 3-11 μg/L; Cpeak 5-17 μg/L) and creatinine concentrations were stable as well. Immunosuppressors variability before and after rivaroxaban were 30% and 30% for tacrolimus, 27% and 29% for everolimus, respectively, as well as 14% and 3% for creatinine. For rivaroxaban monitoring, the reference change value better performed in identifying significant variations of its concentration. No patient had bleeding or thrombotic events, worsening of renal graft function, and signs of immunosuppressants toxicity during a mean follow-up of 23 (9-28) months. In conclusion, rivaroxaban does not seem to interact with tacrolimus and everolimus in renal transplant recipients. Both anticoagulant and immunosuppressive effects seem warranted, without major bleeding complications and effect on the graft function.

Abstract
Objectives Kidney transplant (KTx) recipients frequently have deficient or insufficient levels of serum vitamin D. Few studies have investigated the effect of cholecalciferol in these patients. We evaluated the efficacy of weekly cholecalciferol administration on parathyroid hormone (PTH) levels in stable KTx patients with chronic kidney disease stage 1-3. Methods In this retrospective cohort study, 48 stable KTx recipients (37 males, 11 females, aged 52 ± 11 years and 26 months post-transplantation) were treated weekly with oral cholecalciferol (7500-8750 IU) for 12 months and compared to 44 untreated age- and gender-matched recipients. Changes in levels of PTH, 25(OH) vitamin D (25[OH]D), serum calcium, phosphate, creatinine and estimated glomerular filtration rate (eGFR) were measured at baseline, 6 and 12 months. Results At baseline, clinical characteristics were similar between treated and untreated patients. Considering the entire cohort, 87 (94.6%) were deficient in vitamin D and 64 (69.6%) had PTH ≥130 pg/mL. Serum calcium, phosphate, creatinine and eGFR did not differ between groups over the follow-up period. However, 25(OH)D levels were significantly higher at both 6 (63.5 vs. 30.3 nmol/L, p < 0.001) and 12 months (69.4 vs. 30 nmol/L, p < 0.001) in treated vs. untreated patients, corresponding with a significant reduction in PTH at both 6 (112 vs. 161 pg/mL) and 12 months (109 vs. 154 pg/mL) in treated vs. untreated patients, respectively (p < 0.001 for both). Conclusions Weekly administration of cholecalciferol can significantly and stably reduce PTH levels, without any adverse effects on serum calcium and renal function.

Abstract
Purpose Kidney transplantation is the gold-standard treatment for end stage renal disease. Although different hemodynamic variables, like central venous pressure and mean arterial pressure, have been used to guide volume replacement during surgery, the best strategy still ought to be determined. Respiratory arterial Pulse Pressure Variation (PPV) is recognized to be a good predictor of fluid responsiveness for perioperative hemodynamic optimization in operating room settings. The aim of this study was to investigate whether a PPV guided fluid management strategy is better than a liberal fluid strategy during kidney transplantation surgeries. Identification of differences in urine output in the first postoperative hour was the main objective of this study. Methods We conducted a prospective, single blind, randomized controlled trial. We enrolled 40 patients who underwent kidney transplantation from deceased donors. Patients randomized in the “PPV” group received fluids whenever PPV was higher than 12%, patients in the “free fluid” group received fluids following our institutional standard care protocol for kidney transplantations (10 mL.kg-1. h-1). Results Urinary output was similar at every time-point between the two groups, urea was statistically different from the third postoperative day with a peak at the fourth postoperative day and creatinine showed a similar trend, being statistically different from the second postoperative day. Urea, creatinine and urine output were not different at the hospital discharge. Conclusion PPV guided fluid therapy during kidney transplantation significantly improves urea and creatinine levels in the first week after kidney transplantation surgery.

Abstract
Fluid intelligence (gf) represents a crucial component of human cognition, as it correlates with academic achievement, successful aging, and longevity. However, it has strong resilience against enhancement interventions, making the identification of gf enhancement approaches a key unmet goal of cognitive neuroscience. Here, we applied a spike-timing-dependent plasticity (STDP)-inducing brain stimulation protocol, named cortico-cortical paired associative stimulation (cc-PAS), to modulate gf in 29 healthy young subjects (13 females-mean ± standard deviation, 25.43 years ± 3.69), based on dual-coil transcranial magnetic stimulation (TMS). Pairs of neuronavigated TMS pulses (10-ms interval) were delivered over two frontoparietal nodes of the gf network, based on individual functional magnetic resonance imaging data and in accordance with cognitive models of information processing across the prefrontal and parietal lobe. cc-PAS enhanced accuracy at gf tasks, with parieto-frontal and fronto-parietal stimulation significantly increasing logical and relational reasoning, respectively. Results suggest the possibility of using SPTD-inducing TMS protocols to causally validate cognitive models by selectively engaging relevant networks and manipulating inter-regional temporal dynamics supporting specific cognitive functions.

Abstract
This study reports the utilization of engineered molecular networks between bacteriophage (or phage) and gold nanoparticles (AuNPs) prepared ablating a high purity gold target in water by nanosecond laser source. Gold colloids are assembled with P9b phage clone, displaying the specific peptide (QRKLAAKLT), able to bind P. aeruginosa. The single components and assembled systems were characterized by spectroscopic and electronic techniques, such as the conventional optical absorption and micro-Raman spectroscopies as well as the Dynamic Light Scattering (DLS) and Scanning Transmission Electron Microscopy (STEM) techniques. The performance of the AuNPs-phage assembly as substrate for Surface-Enhanced Raman Spectroscopy (SERS) was tested against the detection of the characteristics Raman vibrational features of the Pseudomonas aeruginosa bacteria.

Abstract
BACKGROUND With the aging of recipients of renal transplantation (RT) one of the emerging issues is the incidence of low urinary tract symptoms (LUTS), which may have negative consequences on the graft survival and function. The aim of our study was to assess the influence of LUTS and the treatment with transurethral resection of the prostate (TURP) on the outcome of RT. MATERIALS AND METHODS We collected data from men over 55 who underwent RT at our center from January 2007 to December 2016. We analyzed the incidence of LUTS; the rate of treatment with TURP; the eGFR (estimated glomerular filtration rate) at 6 months and 1, 3, and 5 years from transplantation; and graft survival. RESULTS Fifty-five patients out of 268 experienced LUTS, and 19 of them had a bladder outlet obstruction (BOO). Patients experiencing BOO had a significantly higher hazard ratio (HR) of graft failure (HR 5.7, CI 1.56-21.4) compared to the other recipients. Of the 18 patients treated with TURP, 10 received the procedure within 6 months from the LUTS onset. They had a significantly absolute eGFR improvement at 6 months from the intervention (+14.25 mL/min ± 8.10) compared to the patients treated later (-8.4 mL/min ± 14.43). DISCUSSION We showed the negative effects of LUTS on kidney graft function and survival. Although TURP is the standard therapy for such an issue, the best timing for it still has to be defined. Our experience supports the need for an early treatment of the LUTS for promoting the outcome of the RT.

Abstract
Malignant brain neoplasms have a poor prognosis despite aggressive treatments. Animal models and evidence from human bodily tumors reveal that sustained reduction in tumor perfusion via electrical stimulation promotes tumor necrosis, therefore possibly representing a therapeutic option for patients with brain tumors. Here, we demonstrate that transcranial electrical stimulation (tES) allows to safely and noninvasively reduce intratumoral perfusion in humans. Selected patients with glioblastoma or metastasis underwent tES, while perfusion was assessed using magnetic resonance imaging. Multichannel tES was applied according to personalized biophysical modeling, to maximize the induced electrical field over the solid tumor mass. All patients completed the study and tolerated the procedure without adverse effects, with tES selectively reducing the perfusion of the solid tumor. Results potentially open the door to noninvasive therapeutic interventions in brain tumors based on stand-alone tES or its combination with other available therapies.

Abstract
Hepatocellular carcinoma (HCC) is the most common liver tumour and represents a significant health burden. The different characteristics of the disease in the various parts of the world, as much as economic and social features, explain only partially the great diversity in the treatment options offered to patients in different countries. The most apparent contrast in term of tumour management is between the western and eastern world. Striking differences involve not only the attitude towards indications for liver transplantation or liver resection but also the surgical techniques adopted. Although remarkable signs of progress have been achieved in surgical and pharmacological fields, univocal guidelines are yet lacking, preventing effective comparisons between retrospective studies and clinical trials. This review aims to analyse and compare some of the most relevant and essential traits of the eastern and western therapeutic strategy against HCC.

Abstract
The development of effective biomarkers for detecting the magnitude of radiation exposure and resiliency of host response is crucial to identifying appropriate treatment strategies after radiation exposure. We hypothesized that the gastrointestinal resident bacteria would demonstrate predictable, dose-dependent changes after radiation exposure across two large animal models of acute radiation syndrome. Here, Göttingen minipigs (GMP) (n = 50) and rhesus macaques (n = 48) were exposed to five dose levels (resulting in mortality rates of 33-100% and 25-68.7%, respectively). Fecal samples taken prior to and after irradiation (day 0 for GMP; day 0, 3 and 14 for macaques) were used for 16S rRNA gene sequence amplicon high-throughput sequencing. Baseline gut microbiota profiles were dissimilar between GMP and macaques, however, radiation appeared to have similar effect at the phylum level, resulting in Bacteroidetes decrease and Firmicutes increase in both models. The abundance of the main Bacteroidetes genus ( Bacteroides for GMP, Prevotella for macaques) was profoundly decreased by irradiation. Intracellular symbionts [Elusimicrobia in GMP, Treponema (Spirochaetes) in macaques] consistently increased after irradiation, suggesting their use as potential biomarkers of intestinal injury, and potential negative effect on health. Prevotella, Lactobacillus, Clostridium XIVa, Oscillibacter and Elusimicrobium/ Treponema abundances were found to be very significantly correlated with radiation intensity. Furthermore, Prevotella, Enterorhabdus and Ruminococcus and Enterorhabdus maintenance was strongly associated with survival in GMP, while Prevotella, Oscillibacter and Treponema were strongly associated with survival and Streptococcus with death in macaques. Overall, we found that a wide range of gut bacterial genera known to be abundant in the human gut microbiota are excellent biomarkers of radiation intensity and resilience in animal models, and that detrimental effects can be monitored, and potentially prevented, by targeting selected genera.

Abstract
In rodent studies, the gut microbiota has been implicated in facilitating both radioresistance, by protecting the epithelium from apoptotic responses and radiosensitivity, inducing endothelial apoptotic responses. Despite the observation that large animal models, such as the Chinese Rhesus macaque and the Gottingen Minipig, demonstrate similarity to human physiologic responses to radiation, little is known about radiation-induced changes of the gut microbiome in these models. To compare the two models, we used bioequivalent radiation doses which resulted in an LD50 for Gottingen Minipigs and Chinese Rhesus macaques, 1.9 Gy and 6.8 Gy, respectively. Fecal samples taken prior and 3 days post-radiation were used for 16S rRNA gene sequence amplicon high throughput sequencing (Illumina MiSeq). Baseline gut microbiota profiles were dissimilar between minipigs and rhesus macaques. Irradiation profoundly impacted gut microbiota profiles in both animals. Significant increases of intracellular symbionts were common to both models and to reported changes in rodents suggesting universality of these findings post-radiation. Remarkably, opposite dynamics were observed for the main phyla, with increase of Firmicutes and decrease of Bacteroidetes and Proteobacteria in minipigs but with enrichment of Bacteroidetes in rhesus macaques. Minipig changes in magnitude and in variety of species affected were more extensive than those observed in rhesus macaques. This pilot study provides an important first step in comparing the radiosensitive pig model to the comparatively more radioresistant macaque model, for the identification of microbial elements which may influence radiosensitivity.

Abstract
Background The persisting organ shortage in the field of transplantation recommends the use of marginal kidneys which poorly tolerate ischemic damage. Adenosine triphosphate (ATP) depletion during cold ischemia time (CIT) is considered crucial for graft function. We tested different strategies of kidney perfusion before transplantation in the attempt to improve the technique. Material/Methods Twenty human discarded kidneys from donors after brain death and with at least 20 hours of CIT were randomized to the following experimental groups (treatment time three-hours at 4°C): a) static cold storage (CS); b) static cold hyperbaric oxygenation (Hyp); c) hypothermic perfusion (PE); d) hypothermic perfusion in hyperbaric oxygenation (PE-Hyp); and e) hypothermic oxygenated perfusion (PE-O2). Results Histological results showed that perfusion with or without oxygen did not produce any endothelial damage. A depletion of ATP content following the preservation procedure was observed in CS, PE, and Hyp, while PE-Hyp and PE-O2 were associated with a net increase of ATP content with respect to baseline level. In addition, PE-Hyp was associated with a significant downregulation of endothelial isoform of nitric oxide synthase (eNOS) gene expression and of hypoxia inducible factor-1α (HIF-1α). Conclusions Hyperbaric or normobaric oxygenation with perfusion improves organ metabolic preservation compared to other methods. This approach may prevent the onset of delayed graft function, but clinical trials are needed to confirm this.

Abstract
Purpose Liver stiffness (LS) has been shown to be of use in chronic liver disease patients but its utility in surgical judgment still needs to be proven. A decision-making approach was applied to evaluate whether LS measurement before surgery of hepatocellular carcinoma (HCC) can be useful in avoiding post-hepatectomy liver failure (PHLF). Materials and Methods Decision curve analysis (DCA) was applied to 202 HCC patients (2008 - 14) with LS measurement prior to hepatectomy to verify whether the occurrence of PHLF grades B/C should be reduced through a decision-making approach with LS. Results Within 90 days of surgery, 4 patients died (2 %) and grades B/C PHLF occurred in 29.7 % of cases. Ascites and/or pleural effusion, treatable with medical therapy, were the most frequent complications. DCA showed that using the "expected utility theory" LS measurement can reduce up to 39 % of cases of PHLF without the exclusion of any patient from surgery that duly undergoes an uncomplicated postoperative course. LS measurement does not add any information to normal clinical judgment for patients with a low (< 10 %) risk of PHLF. Conclusion LS measurement can determine a reduction of PHLF under "expected utility theory" fulfilment. However, the degree of PHLF can be minor and "risk seeking" individuals can accept such a risk on the basis of surgical benefits.

Abstract
The management of recurrent hepatocellular carcinoma untreatable with surgical options is based on systemic therapy with sorafenib. Due to the high rates of adverse events connected to the therapy with sorafenib, metronomic capecitabine seems a promising strategy for these patients. We analyzed the data of 38 patients with hepatocellular carcinoma recurrent after liver transplantation performed at our center. We compared the outcome of 17 patients receiving metronomic capecitabine versus 20 patients experiencing best supportive care and versus the data of the literature about treatment with sorafenib. In the group treated with metronomic capecitabine we observed an increased survival after tumor recurrence at the univariate and multivariate analysis compared to the group of best supportive care (median 22 months vs. 7 months, p < 0.01). Data from the literature on the use of sorafenib showed outcomes like our study group, with similar patient and tumoral features. The episodes of acute rejection and the tumor stage at the recurrence showed a correlation with patient survival at the univariate analysis. The metronomic capecitabine for hepatocellular cancer recurrent after liver transplantation seems effective without important adverse events and comparable results to sorafenib.

Abstract
The aging of the on-dialysis population raises the issue of whether to propose elderly patients for kidney transplantation and how to manage their immunosuppression. This study aimed to analyze the outcome of kidney transplantation on an Italian series of elderly recipients. We included in this retrospective study all patients over 60 years, receiving a deceased-donor kidney transplantation from January 2004 to December 2014 in two north Italian Centers. We analyzed the correlation of recipient age with graft's and patient's survival, delayed graft function, acute cellular rejection (ACR), surgical complications, infections, and glomerular filtration rate. Four hundred and fifty-two patients with a median age of 65 years were included in the study. One-, 3-, and 5-year patient's and graft's survival were, respectively, of 98.7%, 93%, 89% and 94.4%, 87.9%, 81.4%. The increasing recipient age was an independent risk factor only for the patient's (P=.008) and graft's survival (P=.002). ACR and neoplasia were also associated to a worse graft survival. The reduced graft survival in elderly kidney recipients seems to be related more to the increasing recipient's age than to the donor's features. In this population, the optimization of organ allocation and immunosuppression may be the key factors to endorse improvements.

Abstract
BACKGROUND Patients with diabetes are at increased cardiovascular risk. Simultaneous pancreas-kidney transplantation (SPKT) is the treatment of choice in patients with type 1 diabetes mellitus and diabetic nephropathy. We assessed coronary flow reserve (CFR) by transthoracic echocardiography as a marker of major adverse cardiac events (MACE) in SPKT patients. METHODS We studied 48 consecutive SPKT patients (28 male, age at SPKT 54 ± 8 years). Time from transplantation was 8.5 ± 3 years. Follow-up was 4.6 ± 1.8 years. Coronary flow velocity in the left anterior descending coronary artery was detected by Doppler echocardiography at rest and during adenosine infusion. CFR was the ratio of hyperemic diastolic flow velocity (DFV) to resting DFV. A CFR ≤ 2 was considered abnormal and a sign of coronary microvascular dysfunction. MACE were cardiac death, myocardial infarction, and heart failure. RESULTS CFR was 2.55 ± 0.8. CFR was ≤2 in 13 (27%) patients. CFR was lower in SPKT patients with MACE (2.1 ± 0.7 vs 2.7 ± 0.8, P = .03) and patients with MACE had a higher incidence of CFR ≤ 2 (P = .03). Time from transplantation was shorter in patients with MACE (P < .0001). Patients with CFR ≤ 2 had a lower MACE-free survival (P = .03). CFR ≤ 2 predicted the risk of MACE (P = .007) independently from coronary artery disease and metabolic control. However, this predicted role is lost when adjusted for the time from transplantation, which plays a protective role (P = .001). CONCLUSIONS In SPKT, CFR ≤ 2 may be a reliable marker for MACE, independent of coronary artery disease diagnosis. However, this role seems to be reduced over time. This finding suggests a gradual reduction of cardiovascular risk in SPKT patients.

Abstract
The objective of this study was to investigate the inhalation exposure of forest operators to polycyclic aromatic hydrocarbons (PAHs) and BTEX (benzene, toluene, ethylbenzene and total xylenes) contained in the exhaust fumes released from chainsaws and to suggest possible countermeasures. The study was carried out in four silvicultural treatments (coppice clearcut, conifer thinning, conifer pruning, and sanitary cut), using three types of chainsaw fuel (normal two-stroke petrol mix and two alkylate fuels). Eighty personal air samples were collected; IOM samplers combined with Amberlite XAD-2 sorbent tubes were used for collecting PAHs and Radiello® samplers were used for BTEX. Results indicate that none of the four silvicultural treatments significantly affected the PAHs and BTEX inhalation exposure of forest workers. On the other hand, statistically significant differences were recorded in the inhalation exposure to PAHs and BTEX when using different fuel types. In particular, the inhalation exposure to PAHs and BTEX was generally one order of magnitude lower when using modern alkylate fuels as compared to the traditional oil and lead-free petrol mixture. The small, non-statistically significant differences in inhalation exposure recorded between the two alkylate fuels suggests that the two fuels might be equivalent in terms of quality. Our study indicates that while forest workers are exposed to PAHs and BTEX, the maximum values are generally well below accepted occupational exposure limits.

Abstract
As a consequence of the general improvement in the diagnosis and management of rheumatic diseases, patients achieve a better quality of life, with the possibility of a normal family life including one or more pregnancies. It is important, therefore, to consider the psychological aspects of these mothers’ life and the influence of their chronic disease on their children is development. Several papers have reported the impact of systemic lupus erythematosus (SLE) on the quality of life. They found higher incidence of anxiety (from 15 to 45%) and depression (from 25 to 47%) compared to the general population. We have investigated the psychological influence of SLE on family planning, and we observed that it can interfere with physiological phenomena such as parenthood and the upbringing of children. The children of lupus mothers have a normal intelligence level for their age. What is emerging, however, is an increased incidence of learning disabilities compared to the general population. This observation suggests the importance of an early neuropsychological examination, in order to identify the children needing particular care. Therefore, psychological support seems to be an important help in the counseling of patients with rheumatic disease and in the future life of their children.

Abstract
Rheumatic autoimmune diseases have a higher prevalence in women, particularly during their childbearing age. Due to improved management, an increasing number of patients plan and carry out one or more pregnancies. Therefore, a growing interest is being paid to the possible consequences of maternal disease and associated treatment on the fetus and newborn infant. If maternal disease is characterized by the presence of IgG isotype autoantibodies, these can cross the placenta with possible antibody-mediated damage to the fetus. This is typically the case of the so called neonatal lupus erythematosus (NLE); a similar mechanism has been shown in infants of patients with immune thrombocytopenic purpura (ITP) and, less frequently, in those from mothers with antiphospholipid syndrome (APS). Indeed, this last condition is often responsible for placental, rather than neonatal, pathology. In addition, immunosuppressive and other drugs administered to the mothers during pregnancy and lactation might affect the fetal and neonatal immune system development. Finally, mothers disease and/or treatment could be related to neuropsychological alteration reported in some of their children.

Abstract
To verify the neuropsychological development in the offspring of patients with systemic lupus erythematosus (SLE), 47 children (23 male and 24 female) from affected women were studied. The tests applied were related to the children’s ages: Griffiths scale up to four years, WPPSI and metaphonological tests (MP, evaluating the phonological consciousness) from four to six years of age, WISC-R test and Rey test (evaluating the visual-space abilities) from six years onwards; finally, specific tests for the diagnosis of learning disabilities (LD) between the ages of seven and 13. Intelligence levels were always normal (mean IQ score 106.32; median 104; SD 9.05). Three out of eight examined children failed MP, therefore may develop LD and will need further evaluation later. Fourteen children were specifically studied for LD and three reported scores lower than normal, but only two (who were brothers) were defined dyslexic. Antiphospholipid antibodies (aPL) were positive in the mothers of the three children with impaired LD tests. Other maternal autoantibodies or drugs administered during pregnancy did not seem to be related to LD. In conclusion, maternal SLE does not impair intelligence levels, but may increase the occurrence of LD particularly in male children (2/8 males examined, 25%). Both maternal aPL and genetic background may have pathogenetic implications.

Abstract
BACKGROUNDS & AIMS To assess the relationship existing between hepatic venous pressure gradient (HVPG) and the occurrence of post-hepatectomy liver failure (PHLF) grade B/C after resection of hepatocellular carcinoma (HCC) and persistent worsening of liver function. METHODS Data from 70 consecutive prospectively enrolled HCC patients undergoing resection were collected and analysed. PHLF grade B/C was defined by the International Study Group of Liver Surgery recommendations. The appearance of unresolved decompensation was also analysed. RESULTS Postoperative and 90-day mortality were null. The median HVPG value was 9mmHg (range: 4-18) and the median Model for End-stage Liver Disease (MELD) score was 8 (range: 6-14); 34 patients had an HVPG ⩾10mmHg (48.6%). Forty-nine patients had an uneventful (Grade A) postoperative course, including 17 with an HVPG ⩾10mmHg (24.2% of 70 patients). Grade B complications occurred in 20 patients (3 with an HVPG <10mmHg and 17 with an HVPG ⩾10mmHg; p<0.001); only one grade C complication occurred in a patient with an HVPG <10mmHg, subsequently successfully undergoing liver transplantation. Median MELD score returned to preoperative values after a transient postoperative increase, regardless of the HVPG values; after three months, it returned to the preoperative of 8 in patients with an HVPG <10mmHg and of 9 in patients with an HVPG ⩾10mmHg (p=0.077 and 0.076 at paired test, respectively). CONCLUSIONS The hepatic venous pressure gradient can be used before surgery to stratify the risk of PHLF but the proposed cut-off of 10mmHg excludes approximately one-quarter of the patients who would benefit from surgery without short to mid-term postoperative sequelae.

Abstract
In this work a new remotely-triggered drug delivery system based on PEG-PLGA_Au nanocomposite is proposed. Due to the optical properties of gold nanoparticles (Au NPs), the nanovector allows on-demand control of the dose, the timing and the duration of the drug release, upon irradiation with red laser light. The Au NPs are synthesized by laser ablation and subsequently embedded into the PEG-PLGA copolymer via a modified emulsion-diffusion method, devised in such a way that both Au NPs and silibinin (SLB), a flavonolignan with promising anti-neoplastic effects, can be co-loaded into the polymeric system in a single step procedure. A combination of analytical techniques including nuclear magnetic resonance (NMR), static and dynamic light scattering (SLS, DLS), gel permeation chromatography (GPC), thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS), infrared (FTIR) spectroscopy and scanning/transmission electron microscopies (SEM/STEM/TEM), have been used to study the structural and morphological properties of the nanocomposite. The loading efficiency and the drug content, evaluated by UV-vis absorption optical spectroscopy, are 89% and 8.8%, respectively. Upon laser irradiation the system releases the encapsulated drug with a higher efficiency (∼10%) than that without irradiation. This behaviour indicates that our nanoplatform is responsive to light and it could be considered a promising new type of light-activated drug delivery carrier applicable to the biomedical field.

Abstract
In a mass casualty radiation event situation, individualized therapy may overwhelm available resources and feasibility issues suggest a need for the development of population-based strategies. To investigate the efficacy of a population-based strategy, Chinese macaques (n = 46) underwent total-body irradiation and received preemptive antibiotics, IV hydration on predetermined postirradiation days and were then compared to macaques (n = 48) that received subject-based care in which blood transfusions, IV hydration, nutritional supplementation and antibiotic supportive measures were provided. Estimated radiation doses for LD30/60, LD50/60 and LD70/60 of animals with subject-based care: 6.83 Gy (6.21, 7.59), 7.44 Gy (6.99, 7.88) and 8.05 Gy (7.46, 8.64), respectively, and for population-based care: 5.61 Gy (5.28, 6.17), 6.62 Gy (6.13, 7.18) and 7.63 Gy (7.21, 8.20), respectively. Analysis of four time periods, 0-9, 10-15, 16-25 and 26-60 days postirradiation, identified significant mortality differences during the period of 10-15 days. A subset analysis of higher radiation doses (6.75-7.20 Gy, n = 32) indicated hydration, nutrition and septic status were not significantly different between treatments. Whole blood transfusion treatment, administered only in subject-supportive care, was associated with significantly higher platelet and absolute neutrophil counts. Median platelet counts greater than 5,670 cells/μl and absolute neutrophil counts greater than 26 cells/μl during this period correlated with survival. We observed that the population-based treatment increased the LD50/60 compared to nontreatment (6.62 Gy vs. 4.92 Gy) and may be further optimized during days 10-15, where strategic blood transfusions or other strategies to achieve increases in neutrophil and platelet counts may further increase survival rates in subjects exposed to high doses of radiation.

Abstract
Embryonic stem cell (ESC) self-renewal and pluripotency is maintained by an external signaling pathways and intrinsic regulatory networks involving ESC-specific transcriptional complexes (mainly formed by OCT3/4, Sox2 and Nanog proteins), the Polycomb repressive complex 2 (PRC2) and DNA methylation [1], [2], [3], [4], [5], [6], [7], [8]. Among these, Nanog represents the more ESC specific factor and its repression correlates with the loss of pluripotency and ESC differentiation [9], [10], [11]. During ESC early differentiation, many development-associated genes become upregulated and although, in general, much is known about the pluripotency self-renewal circuitry, the molecular events that lead ESCs to exit from pluripotency and begin differentiation are largely unknown. Snai1 is one the most early induced genes during ESC differentiation in vitro and in vivo [12], [13]. Here we show that Snai1 is able to directly repress several stemness-associated genes including Nanog. We use a ESC stable-line expressing a inducible Snai1 protein. We here show microarray analysis of embryonic stem cells (ESC) expressing Snail-ER at various time points of induction with 4-OH. Data were deposited in Gene Expression Omnibus (GEO) datasets under reference GSE57854 and here: http://epigenetics.hugef-research.org/data.php.
