Abstract
BACKGROUND Implementation level of long-acting injectable agents cabotegravir/rilpivirine (LAI CAB/RPV) for human immunodeficiency virus (HIV) treatment in Italy is still not known. The aim of this study is to identify the status of implementation of LAI CAB-RPV and its barriers. MATERIALS AND METHODS A cross-sectional online survey was conducted among infectious diseases (ID) physicians and nurses belonging to the ICONA network in Italy. Three validate 4-items measures were used: Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM) and Feasibility of Intervention Measure (FIM). RESULTS Out of 61 ICONA centres, 38 (62%) completed the survey: 57.9% were academic centres, 42.1% were hospital-based. In total, 104 respondents were ID physicians (57.4%), 77 were nurses (42.5%); 4.5% of all PWH followed at the 38 centres started LAI CAB/RPV at time of study. Centres taking care of >1000 PWH reported 95% application of procedures for LA implementation, higher than other centres (P = 0.009). Mean score of AIM was (16.0, standard deviation, SD, 3.3), of IAM (16.0, SD 3.0) and FIM (16.0, SD 2.9). A linear correlation was found between AIM and the number of people with HIV who started LAI CAB/RPV (25-50 versus <25, coefficient of correlation [b] 2.57, 95%CI 0.91-4.60, P = 0.004), academic versus hospital-based centres (b -1.59, 95%CI -2.76-0.110044, P = 0.007) and the absence of preliminary systematic assessment of staff (b -1.98, 95%CI -3.31-0.65, P = 0.004). Implementation barriers were not significantly different according to the number of PWH/centre. CONCLUSIONS LAI CAB/RPV implementation was low, with a great variability according to centre size. Tailored and centre-specific interventions to address barriers and to optimize the LA treatment implementation should be designed.

Abstract
PURPOSE While SARS-CoV-2 infection appears not to be clinically evident in the testes, indirect inflammatory effects and fever may impair testicular function. To date, few long-term data of semen parameters impairment after recovery and comprehensive andrological evaluation of recovered patients has been published. The purpose of this study was to investigate whether SARS-CoV-2 infection affect male reproductive health. METHODS Eighty patients were recruited three months after COVID-19 recovery. They performed physical examination, testicular ultrasound, semen analysis, sperm DNA integrity evaluation (TUNEL), anti-sperm antibodies (ASA) testing, sex hormone profile evaluation (Total testosterone, LH, FSH). In addition, all patients were administered International Index of Erectile Function questionnaire (IIEF-15). Sperm parameters were compared with two age-matched healthy pre-COVID-19 control groups of normozoospermic (CTR1) and primary infertile (CTR2) subjects. RESULTS Median values of semen parameters from recovered SARS-CoV-2 subjects were within WHO 2010 fifth percentile. Mean percentage of sperm DNA fragmentation (%SDF) was 14.1 ± 7.0%. Gelatin Agglutination Test (GAT) was positive in 3.9% of blood serum samples, but no positive semen plasma sample was found. Only five subjects (6.2%) had total testosterone levels below the laboratory reference range. Mean bilateral testicular volume was 31.5 ± 9.6 ml. Erectile dysfunction was detected in 30% of subjects. CONCLUSION Our data remark that COVID-19 does not seem to cause direct damage to the testicular function, while indirect damage appears to be transient. It is possible to counsel infertile couples to postpone the research of parenthood or ART procedures around three months after recovery from the infection.

Abstract
PURPOSE To study the possible association of CT-derived quantitative epicardial adipose tissue (EAT) and glycemia at the admission, with severe outcomes in patients with COVID-19. METHODS Two hundred and twenty-nine patients consecutively hospitalized for COVID-19 from March 1st to June 30th 2020 were studied. Non contrast chest CT scans, to confirm diagnosis of pneumonia, were performed. EAT volume (cm3) and attenuation (Hounsfield units) were measured using a CT post-processing software. The primary outcome was acute respiratory distress syndrome (ARDS) or in-hospital death. RESULTS The primary outcome occurred in 56.8% patients. Fasting blood glucose was significantly higher in the group ARDS/death than in the group with better prognosis [114 (98-144) vs. 101 (91-118) mg/dl, p = 0.001]. EAT volume was higher in patients with vs without the primary outcome [103 (69.25; 129.75) vs. 78.95 (50.7; 100.25) cm3, p < 0.001] and it was positively correlated with glycemia, PCR, fibrinogen, P/F ratio. In the multivariable logistic regression analysis, age and EAT volume were independently associated with ARDS/death. Glycemia and EAT attenuation would appear to be factors involved in ARDS/death with a trend of statistical significance. CONCLUSIONS Our findings suggest that both blood glucose and EAT, easily measurable and modifiable targets, could be important predisposing factors for severe Covid-19 complications.

Abstract
BACKGROUND Physical inactivity is a key contributor to the global burden of disease and disproportionately impacts the wellbeing of people experiencing mental illness. Increases in physical activity are associated with improvements in symptoms of mental illness and reduction in cardiometabolic risk. Reliable and valid clinical tools that assess physical activity would improve evaluation of intervention studies that aim to increase physical activity and reduce sedentary behaviour in people living with mental illness. METHODS The five-item Simple Physical Activity Questionnaire (SIMPAQ) was developed by a multidisciplinary, international working group as a clinical tool to assess physical activity and sedentary behaviour in people living with mental illness. Patients with a DSM or ICD mental illness diagnoses were recruited and completed the SIMPAQ on two occasions, one week apart. Participants wore an Actigraph accelerometer and completed brief cognitive and clinical assessments. RESULTS Evidence of SIMPAQ validity was assessed against accelerometer-derived measures of physical activity. Data were obtained from 1010 participants. The SIMPAQ had good test-retest reliability. Correlations for moderate-vigorous physical activity was comparable to studies conducted in general population samples. Evidence of validity for the sedentary behaviour item was poor. An alternative method to calculate sedentary behaviour had stronger evidence of validity. This alternative method is recommended for use in future studies employing the SIMPAQ. CONCLUSIONS The SIMPAQ is a brief measure of physical activity and sedentary behaviour that can be reliably and validly administered by health professionals.

Abstract
In the present study we describe the molecular characterization of the two paralogous mitochondrial peroxiredoxins from Trematomus bernacchii, a teleost that plays a pivotal role in the Antarctic food chain. The two putative amino acid sequences were compared with orthologs from other fish, highlighting a high percentage of identity and similarity with the respective variant, in particular for the residues that are essential for the characteristic peroxidase activity of these enzymes. The temporal expression of Prdx3 and Prdx5 mRNAs in response to short-term thermal stress showed a general upregulation of prdx3, suggesting that this isoform is the most affected by temperature increase. These data, together with the peculiar differences between the molecular structures of the two mitochondrial Prdxs in T. bernacchii as well as in the tropical species Stegastes partitus, suggest an adaptation that allowed these poikilothermic aquatic vertebrates to colonize very different environments, characterized by different temperature ranges.

Abstract
BACKGROUND Assessment of potential liver allograft donors with frozen sections has clinical relevant consequences for the transplant recipient. Several clinical risk factors have been identified that increase the risk of transplantation failure and it is critical for the pathologist to become familiar with the histologic criteria for donor liver suitability. In this setting an accurate and reliable assessment of fibrosis is crucial. We sought to report the value of the rapid chromotrope aniline blue stain (CAB) in a transplantation clinical work-flow for scoring liver fibrosis. MATERIALS AND METHODS Twenty consecutive intraoperative donor liver biopsy specimens were evaluated by a pathologist at the Transplant Pathology Board Room, AOUI Verona, during 24-hour on-call service. The stage of fibrosis was evaluated according to Ishak score ranging from 0 to 6 (absent to cirrhosis) using hematoxylin and eosin stain (H&E) plus rapid CAB special stain. After a 3-week washout period, only the slides stained with H&E were re-assessed for fibrosis stage by the same pathologist blinded to donor patient data. RESULTS Combination H&E-CAB staging fibrosis score was higher in 20%, lower in 10%, and the same in 70% of biopsy specimens as determined using only H&E stain alone. Rapid CAB stain takes 20 minutes longer than H&E stain alone. CONCLUSIONS CAB staining may be performed on frozen tissue from liver biopsy during a transplantation process without a significant delay in diagnosis. Combination H&E-CAB staining improves sensibility of interpretation of fibrosis.

Abstract
The Venetian Plain is known for the occurrence of areas with high concentrations of arsenic in groundwater (greater than 400 μg/L). The study area represents the typical residential, industrial and agricultural features of most Western countries and is devoid of hydrothermal, volcanic or anthropogenic sources of arsenic. The aim of the study is to model the arsenic mobilization and the water-rock interaction by a complete hydrogeochemical investigation (analyses of filtered and unfiltered groundwater sediment mineralogy and geochemistry). The groundwater arsenic contamination and redox conditions are highly variable. Groundwaters with oxidizing and strongly reducing potentials have much lower arsenic concentrations than do mildly reducing waters. The grain size of the aquifer sediments includes gravels, sands and silty-clays. A continuous range of organic material concentrations is observed (from zero to 40%). The amount of sedimentary organic matter is highly correlated with the arsenic content of the sediments (up to 300 mg/kg), whereas no relationships are detectable between arsenic and other chemical parameters. The occurrence of arsenic minerals was observed as a peculiar feature under the scanning electron microscope. Arsenic and sulfur are the sole constituents of small tufts or thin crystals concentrated in small masses. These arsenic minerals were clearly observed in the peat sediments, in agreement with the geochemical modeling that requires very reducing conditions for their precipitation from the groundwater. The modeling suggests that, under oxidizing conditions, arsenic is adsorbed; moreover, a continuous decrease in the redox potential causes increasing desorption of arsenic. If the reducing conditions become more intense, the formation of As-S minerals would explain the lower concentration of arsenic measured in the strongly reducing groundwater. Even if As-sulfides are rare under low-temperature conditions, the anomalous abundance of reductants (organic matter) can locally stabilize As-S minerals, which can scavenge large quantities of groundwater arsenic.

Abstract
In the present study, we describe the purification and molecular characterization of two peroxiredoxins (Prdxs), referred to as Prdx6A and Prdx6B, from Trematomus bernacchii, a teleost widely distributed in many areas of Antarctica, that plays a pivotal role in the Antarctic food chain. The two putative amino acid sequences were compared with Prdx6 orthologs from other fish, highlighting a high percentage of identity and similarity with the respective variant, in particular for the residues that are essential for the characteristic peroxidase and phospholipase activities of these enzymes. Phylogenetic analyses suggest the appearance of the two prdx6 genes through a duplication event before the speciation that led to the differentiation of fish families and that the evolution of the two gene variants seems to proceed together with the evolution of fish orders and families. The temporal expression of Prdx6 mRNA in response to short-term thermal stress showed a general upregulation of prdx6b and inhibition of prdx6a, suggesting that the latter is the variant most affected by temperature increase. The variations of mRNA accumulation are more conspicuous in heart than the liver, probably related to behavioral changes of the specimens in response to elevated temperature. These data, together with the peculiar differences between the molecular structures of the two Prdx6s in T. bernacchii as well as in the tropical species Stegastes partitus, suggest an adaptation that allowed these poikilothermic aquatic vertebrates to colonize very different environments, characterized by different temperature ranges.

Abstract
INTRODUCTION Organ transplant recipients show an increased incidence of cancer ranging from 4% to 16% owing to several causes: immunosuppression, viral infection, individual predisposition, and so on. MATERIALS AND METHODS We retrospectively reviewed the records of 43/683 (6.3%) recipients of 734 liver transplants performed from November 1991 to November 2008 who experienced a de novo neoplasm. CONCLUSION Alcohol abuse significantly increased the rate of all de novo neoplasms and particularly pharyngogastroesophageal cancers among population of liver transplant recipients. Minimization of immunosuppressive therapy is necessary to reduce the risk of a de novo neoplasm. Strict posttransplant follow-up is required to identify early gastroenteric tumors.

Abstract
AIM to clarify the reliability of two clinical meniscal tests, McMurray's and Apley's and the MRI imaging, in order to establish how to reduce unjustified arthroscopies. METHODS 102 patients were selected out of 160. All patients were submitted to a triple clinical examination (by a young surgeon and two skilled surgeons), MRI and an arthroscopic procedure. The investigated clinical tests were McMurray's and Apley's test. The positivity or negativity of the tests and MRI were compared to arthroscopic findings. Arthroscopy is considered the gold standard for the diagnosis of meniscal lesions. We measured the length of the meniscal lesions in order to correlate it to the clinical findings. RESULTS From the clinical examination, we got the following data: McMurray's test: sensitivity 79.7%, specificity 78.5%, accuracy 79.4%, positive likelihood ratio 3.7, negative likelihood ratio 0.2. Apley's test: sensitivity 83.7%, specificity 71.4%, accuracy 80.3%, positive likelihood ratio 2.9, negative likelihood ratio 0.2. The composite assessment is strictly dependent on how the discordance of the two tests is evaluated. The assessment of the clinical tests was done even in relation to medial or lateral meniscal lesion. No statistical difference was found about the length of the meniscal tear. MRI gave the following results: sensitivity 78.3%, specificity 85.7%, accuracy 80.3%. CONCLUSIONS If we use, as diagnostic means, McMurray's and Apley's clinical tests and MRI as imaging procedure, we have an accuracy of about 80%. It is important to keep in mind that it is not possible to have the absolute certainty of make a correct diagnosis in case of meniscal lesions. Patients, too, have to be informed about the risk of a negative arthroscopy.

Abstract
Surgical resection for malignant hepatic tumors, especially hepatocarcinoma (HCC), has been demonstrated to increase overall survival; however, the majority of patients are not suitable for resection. Radiofrequency ablation (RFA) is the most widely used modality for radical treatment of small HCC (<3 cm). It improves 5-year survival compared with standard chemotherapy and chemical ablation, allowing down-staging of unresectable hepatic masses. Microwave ablation (MWA) has been extensively applied in Asia and was recently introduced in the United States of America and Europe with excellent results, especially with regard to large unresectable HCC. Our single-center experience between May 2009 and October 2010 included application of MWA to 154 patients of median age ± standard deviation of 63.5 ± 8.5 years, 6 males, and 1 female, of mean Model for End-Stage Liver Disease (MELD) score (10.1 ± 3.8). The HCC included, hepatitis C virus (HCV)-related (n=70; 45.5%); alcool (ETOH)-related (n=42; 27%), hepatitis B virus (HBV)-related (n=16; 10.5%); and cryptogenic cases (n=26; 17%). The cases were performed for radical treatment down-staging for multifocal pathology or bridging liver transplantation to orthotopic (OLT) in selected patients with single nodules. A computed tomography (CT) scan was performed at 1 month after the surgical procedure to evalue responses to treatment. Among 6 selected patients who underwent OLT; 5 (83.3%) showed disease-free survival at one-year follow-up. The radical treatment achieved no intraoperative evidence of tumor spread or of pathological signs of active HCC among the explanted liver specimens. In conclusion, a MWA seemed to be a safe novel approach to treat HCC and could serve as a "bridge" to OLT and down-staging for patients with HCC.

Abstract
BACKGROUND Long-term survival rates after orthotopic liver transplantation (OLT) for patients with hepatocellular carcinoma (HCC) of any size and number may now be predicted using the Metroticket calculator. The aim of this study was to evaluate the minimum post-OLT survival threshold that would justify the selection of a patient with HCC for OLT. METHODS We used a Markov model, recently developed at the University of Michigan, which assumes that a patient with HCC should undergo OLT if his or her transplant benefit is greater than the cumulative harm to the rest of the waiting list (WL). In the base case, we considered a patient with a low survival perspective without OLT (5-year survival rate, 10%). The data sources to construct and validate the model were as follows: the Organ Procurement and Transplantation Network report, and our prospective database. RESULTS Our center was generally characterized by lower WL mortalities, although there were lower transplant probabilities for both HCC and non-HCC patients than the average US center. The proportion of HCC patients on the WL was higher in Padua (25%) than in the United States (10%). The calculated harm to the WL was 434 quality-adjusted days of life in Padua, and 957 in the United States (P < .01). The OLT benefit outweighed the harm to the WL when the 5-year post-OLT survival rate was higher than 30% in Padua, and 61% in the United States. CONCLUSIONS In a decision model including the concepts of transplantation benefit and harm to the WL, the minimum 5-year post-OLT survival threshold justifying the selection of a patient with HCC for OLT in Padua was 30%.

Abstract
Tumor progression before orthotopic liver transplantation (OLT) is the main cause of dropouts from waiting lists among patients with hepatocellular carcinoma (HCC). Performing a porto-caval shunt (PCS) before parenchymal liver transection has the potential to allow an extended hepatectomy in patients with decompensated liver cirrhosis, reducing portal hyperflow and therefore the sinusoidal shear-stress on the remnant liver. We report the case of a 59-year-old man affected by hepatitis C virus (HCV)-related decompensated liver cirrhosis (Child Pugh score presentation, C-10; Model for End Stage Liver Disease score, 18) and HCC (2 lesions of 2 and 2.8 cm). The patient began the evaluation to join the OLT waiting list, but, in the 3 months required to complete the evaluation, he developed tumor progression: 3 HCC lesions, the largest 1 with a diameter of about 4.4 cm. These findings excluded transplantation criteria and the patient was referred to our center. After appropriate preoperative studies, the patient underwent a major liver resection (trisegmentectomy) after side-to-side PCS by interposition of an iliac vein graft from a cadaveric donor. The patient overcame the worsened severity of cirrhosis. After 6 months of follow-up, he developed 2 other HCC nodules. He was then included on the waiting list at our center, undergoing OLT from a cadaveric donor at 8 months after salvage treatment. At 36 months after OLT, he is alive and free from HCC recurrence. Associating a partial side-to-side PCS with hepatic resection may represent a potential salvage therapy for patients with decompensated cirrhosis and HCC progression beyond listing criteria for OLT.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) competes with benign liver disease as indication for liver transplantation (OLT). The aim of this study was to determine long-term results of OLT for HCC. METHODS We retrospectively analyzed the prognostic role of HCC diagnosis at pathological exam in adult OLT. In the HCC group, we evaluated the prognostic role of the time of diagnosis (incidental versus nonincidental) and of pathological tumor TNM staging. The primary endpoint was 1-, 3-, and 10-year patient survivals. RESULTS From 1991 to 2006, among 550 adults who underwent first OLT, HCC was found in 120 patients at pathological exam. In 26 cases (22%), the diagnosis of HCC was incidental. There were 59 cases (49%) of pathological T1 to T2 tumor (one nodule < 5 cm, or two to three nodules < 3 cm, without metastases and/or vascular invasion), and 61 cases (51%) of pathologic T3-T4a tumor. HCC diagnosis did not show a significant prognostic impact by Cox survival analysis. After a median follow-up of 31 months, 1-, 5-, and 10-year survivals were 91%, 81%, and 73% in the HCC group, and 84%, 76%, and 67% in the non-HCC group. Time of HCC diagnosis (incidental versus nonincidental) and pathological TNM staging (T1 to T2 vs T3 to T4a) did not result significant survival predictors upon Cox analysis. CONCLUSION In our experience, the long-term results of OLT for HCC overlapped those of OLT for benign disease, although 51% of tumors were T3 to T4a at pathological exam.

Abstract
INTRODUCTION Liver transplantation represents the gold standard for the treatment of chronic liver disease. The whole transplantation process was assessed using an intention-to-treat analysis and considering patients from the time of their inclusion on the list and throughout lengthy follow-up. MATERIALS AND METHODS From January 1, 1999 to June 1, 2004, 373 adults joined the waiting list for liver transplantation at our institution. The main variables analyzed were: age, gender, etiology, Model for End-stage Liver Disease score, Child-Pugh class, United Network for Organ Sharing (UNOS) status. Global survival was evaluated using intention-to-treat analysis from the time of patient inclusion in the list to the end of their late follow-up. RESULTS The median waiting time was 20 months (range 0.1 to 70.2). By univariate analysis, the variables significantly influencing survival when patients joined the waiting list were: encephalopathy; ascites, poor nutritional status, Child-Pugh class C, UNOS 2, hepatitis C virus (HCV) and bilirubin > 2 mg/dL. By multivariate analysis, only HCV-related cirrhosis emerged as having an independent prognostic value. By intention-to-treat analysis, the 5-year survival rate was 67% and 79% for HCV-positive and HCV-negative patients, respectively (P = .0003). CONCLUSIONS HCV-related cirrhosis is an independent prognostic factor for survival according to an intention-to-treat analysis. Different inclusion criteria or treatments while on the waiting list and after transplantation need to be considered in the future for HCV-positive patients.

Abstract
BACKGROUND/AIM The main indications for combined liver and kidney transplantation (CLKT) are as follows: (1) cirrhosis with renal damage dependent or not upon liver disease, (2) renal failure with dialysis and concomitant liver end-stage disease, (3) congenital diseases, and (4) enzymatic liver deficiency with concomitant renal failure. The aim of this study was to evaluate our results with CLKT both in adult and pediatric patients. METHODS From September 1995 to September 2006, 15 CLKT (2.8%) among 541 liver transplantations included 4 pediatric patients (27%). The main indications for CLKT were hepatitis C virus (HCV) and polycystic diseases in adult patients, and primary hyperoxaluria in pediatric patients. RESULTS The double transplantation was performed from the same donor in all cases. All adult patients received whole liver grafts, whereas 3 split transplants and 1 whole liver graft were transplanted in the pediatric patients. Median liver and kidney cold ischemia times were 468 and 675 minutes, respectively. After a median follow-up of 36 months (range, 1-125), the overall survival rate was 80%. Five-year patient and graft survival rates were 100% for adult CLKT, whereas they were 50% for pediatric patients. We observed only 2 cases (18%) of delayed renal function, requiring temporary hemodialysis with progressive graft improvement. There was only 1 case of kidney retransplantation due to early graft nonfunction in a pediatric patient. CONCLUSION Although CLKT is related to major surgical risks, results after transplantation are satisfactory with an evident immunological advantage.

Abstract
Liver transplantation still represents the only effective treatment for patients with liver failure, but many patients die while awaiting transplantation, even though many attempts have been made to increase the organ procurement rates and to partially support hepatic function in recent years. Our aim was to design an "open" ex vivo perfused liver model to simplify liver support using an isolated porcine liver perfused with arterial and portal blood from the recipient pig, while monitoring the metabolic capacity of the supporting graft. It was possible to perfuse the isolated liver for 6 hours as a bridging procedure with satisfactory hemodynamic homeostasis controlled by software biofeedbacks.

Abstract
BACKGROUND/AIMS The aim of this retrospective study is to analyze the prognostic impact of Model for End-Stage Liver Disease (MELD) score in patients undergoing liver transplantation (OLT) with suboptimal livers. METHODS Between January 2002 and January 2006, 160 adult patients with liver cirrhosis received a whole liver for primary OLT at our institution including 81 with a suboptimal liver (SOL group) versus 79 with an optimal liver (group OL). The definition of suboptimal liver was: one major criterion (age >60 years, steatosis >20%) or at least two minor criteria: sodium >155 mEq/L, Intensive Care Unit stay >7 days, dopamine >10 microg/kg/min, abnormal liver tests, and relevant hemodynamic instability. RESULTS Baseline recipients characteristics were comparable in the two study groups. The SOL group had a significantly greater number of early graft deaths (<30 days) than the OL group, while the 3-year Kaplan-Meier patient survivals were similar. Using logistic regression, MELD score was significantly related to patient death only in the SOL group (P = .01), and the receiver operator characteristics curve method identified 17 as the best MELD cutoff with the 3-year survival of 93% versus 85% for MELD < or =7 versus >17, respectively (P > 05). In comparison, it was 94% and 72% in the SOL group (P < .05). Similarly, MELD >17 was significantly associated with early graft death rates only in the SOL group. CONCLUSION This study advised surgeons to not use suboptimal livers for patients with advanced MELD scores, thus supporting a donor-recipient matching policy.

Abstract
OBJECTIVE The objective of this study was to analyze experience on pediatric liver transplantation (LT) between June 1993 and September 2006, including split liver transplantation (SLT), living donor liver transplantation (LDLT), and auxiliary partial orthotopic liver transplantation (APOLT). Furthermore, hepatocyte transplantation (HT) had a role in one patient with metabolic disease. METHODS From November 1990 to September 2006, 657 LTs were performed including 63 pediatric LTs (9.6%) in 57 patients (32 boys and 25 girls). Six were retransplantations (9.5%). Thirty-two patients (57%) were younger than 5 years. The types of graft included the following: 26 whole organs (41%), 32 in situ split organs (51%), 4 reduced-size organs (6%), and 1 graft from a living donor (2%). Two patients received an APOLT, 4 patients received a combined kidney-liver transplantation (CKLT), and 1 patient received HT. Of the 63 pediatric LTs, 16 were behaved to be highly urgent (25%). RESULTS Overall 1-, 3-, 5-, and 10-year patient survival rates were 82%, 82%, 78%, and 78%, respectively. Overall 1-, 3-, 5-, and 10-year graft survival rates were 76%, 76%, 72%, and 72%, respectively. In patients younger than 1 year, the 5-year survival rate was 100%. Perioperative mortality was 8.8%. Vascular complications occurred in 4 patients (6.3%). Six children required retransplantation due to primary nonfunction (PNF) in 4 cases (7%) and vascular thrombosis in 2 cases (3.5%). CONCLUSIONS Cholestatic liver disease and age younger than 1 year were the best prognostic factors for excellent survival.
