Abstract
Pediatric solid organ transplantation (SOT) is a preferred treatment for medically suitable children with end-stage organ failure. Still, many of them have no access to transplantation owing to socioeconomic constraints or lack of transplant facilities in low- and middle-income countries (LMIC). Establishing pediatric SOT programs in LMIC offers children the opportunities to receive transplant care in more familiar home environments as well as help curtail transplant tourism and improve transplant outcomes as pediatric transplantation would be performed ethically and legally. The International Pediatric Transplant Association (IPTA) is a professional organization aiming to promote safe, ethical, and high-quality pediatric transplantation worldwide. This society paper describes major obstacles to pediatric SOT in LMIC and provides guidance on developing and/or expanding pediatric SOT programs in such countries. We also summarize available resources from the IPTA Outreach Program to help establish and support pediatric SOT programs in LMIC.

Abstract
This study aimed to compare liver transplantation (LT) outcomes and evaluate the potential rise in numbers of LT candidates with hepatocellular carcinoma (HCC) of different allocation policies in a high waitlist mortality region. Three policies were applied in two Latin American cohorts (1085 HCC transplanted patients and 917 listed patients for HCC): (i) Milan criteria with expansion according to UCSF downstaging (UCSF-DS), (ii) the AFP score, and (iii) restrictive policy or Double Eligibility Criteria (DEC; within Milan + AFP score ≤2). Increase in HCC patient numbers was evaluated in an Argentinian prospective validation set (INCUCAI; NCT03775863). Expansion criteria in policy A showed that UCSF-DS [28.4% (CI 12.8-56.2)] or "all-comers" [32.9% (CI 11.9-71.3)] had higher 5-year recurrence rates compared to Milan, with 10.9% increase in HCC patients for LT. The policy B showed lower recurrence rates for AFP scores ≤2 points, even expanding beyond Milan criteria, with a 3.3% increase. Patients within DEC had lower 5-year recurrence rates compared with those beyond DEC [13.3% (CI 10.1-17.3) vs 24.2% (CI 17.4-33.1; P = 0.0006], without significant HCC expansion. In conclusion, although the application of a stricter policy may optimize the selection process, this restrictive policy may lead to ethical concerns in organ allocation (NCT03775863).

Abstract
BACKGROUND & AIMS An optimal allocation system for scarce resources should simultaneously ensure maximal utility, but also equity. The most frequent principles for allocation policies in liver transplantation are therefore criteria that rely on pre-transplant survival (sickest first policy), post-transplant survival (utility), or on their combination (benefit). However, large differences exist between centers and countries for ethical and legislative reasons. The aim of this study was to report the current worldwide practice of liver graft allocation and discuss respective advantages and disadvantages. METHODS Countries around the world that perform 95 or more deceased donor liver transplantations per year were analyzed for donation and allocation policies, as well as recipient characteristics. RESULTS Most countries use the model for end-stage liver disease (MELD) score, or variations of it, for organ allocation, while some countries opt for center-based allocation systems based on their specific requirements, and some countries combine both a MELD and center-based approach. Both the MELD and center-specific allocation systems have inherent limitations. For example, most countries or allocation systems address the limitations of the MELD system by adding extra points to recipient's laboratory scores based on clinical information. It is also clear from this study that cancer, as an indication for liver transplantation, requires special attention. CONCLUSION The sickest first policy is the most reasonable basis for the allocation of liver grafts. While MELD is currently the standard for this model, many adjustments were implemented in most countries. A future globally applicable strategy should combine donor and recipient factors, predicting probability of death on the waiting list, post-transplant survival and morbidity, and perhaps costs. LAY SUMMARY An optimal allocation system for scarce resources should simultaneously ensure maximal utility, but also equity. While the model for end-stage liver disease is currently the standard for this model, many adjustments were implemented in most countries. A future globally applicable strategy should combine donor and recipient factors predicting probability of death on the waiting list, post-transplant survival and morbidity, and perhaps costs.

Abstract
BACKGROUND The increase in the waiting list for a liver and the high mortality rate of patients with terminal liver disease represent serious public health problems in Brazil. OBJECTIVE To analyze donations and liver transplants in the State of Paraná, Brazil. METHOD A cross-sectional study was carried out with data from 3931 reports of deaths due to brain death and 8146 solid organ transplants made available by the State Transplant System of Paraná between 2011 and 2016. The data related to donation and liver transplantation were analyzed using descriptive statistics and inference. RESULTS A total of 751 (28.9%) liver donations were carried out. Of these, the greatest chance of effectiveness occurred in patients younger than 50 years OR: 1.94 (CI: 1.60-2.34; P < .01) and male OR: 1.27 (CI: 1.06-1.52; P < .01). A total of 720 (8.8%) liver transplants were performed, most of which were funded by the Unified Health System. There was a significant increase in donations and liver transplants over the years. CONCLUSION Donor numbers and liver transplants increased in the State but did not meet the need for the waiting list within the analyzed period.

Abstract
Liver transplantation (LT) was performed for the first time in Chile in 1969, but only since the 1990s has it been systematically performed. Our health system is strongly centralized, which is a severe limitation for the patients who need to be evaluated and subsequently listed. Although proper human and technological resources are available and our results are comparable to international outcomes (overall patient survival at 1, 5, and 10 years of 82%, 70%, and 64%, respectively), we are limited because of a severe scarcity of grafts, which translates into an availability of approximately 7 organs per million persons and a wait-list dropout rate of 40% every year. Thus, our main challenge for the next few years is to improve access to LT among the populations from the extreme regions of the country and overall to improve the availability of grafts by increasing the awareness of physicians in intensive care units and emergency departments, to develop living donor LT programs, to educate the population in order to decrease family refusal, and to reinforce the system of potential donor detection. Although hard work is mandatory for these improvements, none of these tasks seem to be unreachable in the midterm.

Abstract
BACKGROUND AND RATIONALE The Transplanted Organ Questionnaire (TOQ), developed in France, is a disease-targeted instrument designed to evaluate what the transplanted organ represents to the recipient in patients who have undergone liver transplantation. The present study sought to validate a version of the TOQ for use in the Brazilian population. Translation and cross-cultural adaptation were carried out in accordance with international standard practices. Convergent validity was measured by correlations between TOQ domains and the Beck Depression Inventory (BDI), while reliability was assessed by measurement of internal consistency (Cronbach's alpha coefficient), reproducibility (intraclass correlation coefficient), sensitivity to change (effect size), and floor and ceiling effects. RESULTS The study sample comprised 122 liver transplant recipients, with a mean age of 56.7 ± 9.9 years, treated at the outpatient clinic of a tertiary hospital in Southern Brazil. The sample was largely male (57.4%), and the predominant indication for liver transplant was hepatocellular carcinoma (34.4%). The mean total TOQ score was 32.9 ± 18.0. Cronbach's alpha for the total score was 0.89 (95%CI 0.86-0.92). Correlations between TOQ and BDI domains were acceptable, with the rejection domain correlating most strongly (r = 0.37; p ≤ 0.001). In conclusion, the Brazilian Portuguese version of the TOQ exhibited good psychometric performance, suggesting that it can be a useful tool in the Brazilian cultural context.

Abstract
BACKGROUND AND AIM Non-alcoholic fatty liver disease (NAFLD) is an increasing cause of hepatocellular carcinoma (HCC) and liver transplantation (LT). Our study focused on changing trends of liver related HCC etiologies during the last years in Latin America. METHODS From a cohort of 2761 consecutive adult LT patients between 2005 and 2012 in 17 different centers, 435 with HCC were included. Different periods including years 2005-2006, 2007-2008, 2009-2010 and 2011-2012 were considered. Etiology of liver disease was confirmed in the explant. RESULTS Participating LT centers per country included 2 from Brazil (n=191), 5 transplant programs from Argentina (n=98), 2 from Colombia (n=65), 4 from Chile (n=49), 2 from Mexico (n=12), and 1 from Peru (n=11) and Uruguay (n=9). Chronic hepatitis C infection was the leading cause of HCC in the overall cohort (37%), followed by HBV (25%) and alcoholic liver disease (17%). NAFLD and cryptogenic cirrhosis accounted for 6% and 7%, respectively. While HCV decreased from 48% in 2005-06 to 26% in 2011-12, NAFLD increased from 1.8% to 12.8% during the same period, accounting for the third cause of HCC. This represented a 6-fold increase in NAFLD-HCC, whereas HCV had a 2-fold decrease. Patients with NAFLD were older, had lower pre-LT serum AFP values and similar 5-year survival and recurrence rates than non-NAFLD. CONCLUSION There might be a global changing figure regarding etiologies of HCC in Latin America. This epidemiological change on the incidence of HCC in the world, although it has been reported, should still be confirmed in prospective studies.

Abstract
BACKGROUND Around 2.4% of the world's population is infected with hepatitis C virus (HCV), and it is the most common cause of liver transplantation (LT) in the world. Latin America (LA), with nearly 9% of the world population, has had a continuous increase in the number of LTs per year. Yet, due to the lack of mandatory data collection and a well-developed health-care system, access to transplantation is limited in most LA countries. We report the first LA experience of HCV-infected LT patients. METHODS We performed a retrospective cohort study by reviewing the medical histories of all HCV-infected LT patients between 1996 and 2016 who acquired HCV before their LT, at the Fundación Valle del Lilí, Cali, Colombia. RESULTS Between January 1996 and December 2015, a total of 770 LTs were performed, of which 75 had a cirrhotic liver due to HCV infection. With a median follow-up time of 24.4 months (interquartile range [IQR] 4.7-61.2 months), patient survival was 44.9% and 66.9% for the time periods 1996-2006 and 2007-2015, respectively. Hepatocellular carcinoma (HCC) was present in 30.6% of the patients, and overall postoperative complications had an incidence of 80%. CONCLUSIONS This is the first report of LT in HCV-infected patients in Colombia and in LA. Our results are comparable to those of other transplant centers worldwide with regard to postoperative complications and patient survival. Patients with LT in the 1996-2006 time frame had higher morbidity and mortality. Studies including larger numbers of patients are needed to determine the reason for this finding.

Abstract
Post-liver transplantation diabetes mellitus (PLTDM) develops in up to 30% of liver transplant recipients and is associated with increased risk of mortality and multiple morbid outcomes. PLTDM is a multicausal disorder, but the main risk factor is the use of immunosuppressive agents of the calcineurin inhibitor (CNI) family (tacrolimus and cyclosporine). Additional factors, such as pre-transplant overweight, nonalcoholic steatohepatitis and hepatitis C virus infection, may further increase risk of developing PLTDM. A diagnosis of PLTDM should be established only after doses of CNI and steroids are stable and the post-operative stress has been overcome. The predominant defect induced by CNI is insulin secretory dysfunction. Plasma glucose control must start immediately after the transplant procedure in order to improve long-term results for both patient and transplant. Among the better known antidiabetics, metformin and DPP-4 inhibitors have a particularly benign profile in the PLTDM context and are the preferred oral agents for long-term management. Insulin therapy is also an effective approach that addresses the prevailing pathophysiological defect of the disorder. There is still insufficient evidence about the impact of newer families of antidiabetics (GLP-1 agonists, SGLT-2 inhibitors) on PLTDM. In this review, we summarize current knowledge on the epidemiology, pathogenesis, course of disease and medical management of PLTDM.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the most frequent primary malignant liver tumor, with the Milan criteria considered to be the gold standard for patient selection for liver transplantation (LT). MATERIALS AND METHODS We performed a descriptive observational study, reviewing 20 years of experience of LT in patients with HCC in the Fundacion Valle del Lilí in Cali, Colombia. Subgroup analysis was undertaken for periods 1999 to 2007 and 2008 to 2015. RESULTS Fifty-seven cases with a pretransplant HCC diagnosis were reviewed. In the first period patients within the Milan criteria had a recurrence-free survival at 5 years of 66.6%, and in those who exceeded the Milan criteria, recurrence-free survival was 75%. In the second period, patients within the Milan criteria, recurrence-free survival at 5 years was 93.5%, and in those who exceeded the Milan criteria, recurrence-free survival was 75.7%. No statistically significant difference was found in either period. For patients with mild and moderate tumor differentiation, the relapse survival rate at 5 years was 69.4% (95% confidence interval [CI] 35.8-87.8) and 74.7% (95% CI 44.5-90), respectively. All patients with poor tumor differentiation relapsed and died within 3 years. CONCLUSION Global and recurrence-free survival among patients who met and patients who exceeded the Milan criteria was not significantly different, suggesting an expansion of the Milan criteria to include potential recipients who were previously excluded. Obtaining histologic differentiation and identifying vascular invasion will provide a more worthwhile contribution to LT decision making.

Transplant Proc 2018; 50:387-390. [PMID: 29579809 DOI: 10.1016/j.transproceed.2017.12.049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2017] [Accepted: 12/05/2017] [Indexed: 10/17/2022]
Abstract
BACKGROUND The number of transplants performed relies, partially, on recipients' variables on the waiting list. The goal of this study was to compare recipients from a high-volume liver center in Argentina with the rest of the country. METHODS This study was a retrospective analysis of liver transplant recipients nationally between January 2013 and April 2017. It involved extracting data from the open database CRESI-SINTRA (the Argentinian database of the National Procurement Organization, an equivalent to the United Network for Organ Sharing); expressing results by percentages, medians, and interquartile ranges (IQRs); and comparing the national population with the population transplanted at Hospital El Cruce (HEC). The Mann-Whitney U test was used for analysis. RESULTS Nationally, 1434 liver transplants were performed. A total of 177 (12.34%) were emergency status; 811 (56.6%) were by the Model for End-Stage Liver Disease (MELD) (n = 759)/PELD (Pediatric End-Stage Liver Disease) (n = 52), with a median graft assignment position of 5 (IQR, 3-10) in 57.2 days (IQR, 11-217). Median MELD access was 29 points (IQR, 24-33). A total of 446 (31.1%) had MELD exceptions; 249 (55.8%) of these were due to Milan hepatocellular carcinoma. At the HEC, 167 liver transplantations were performed; 26 (15.6%) were emergency status and 97 (58.1%) by MELD (none PELD). Their median graft assignment position was 4 (IQR, 4-16) in 19.1 days (IQR, 4-90); median MELD access was 28 points (IQR, 24-31). Forty-five patients (26.9%) had MELD exceptions; 31 (68.9%) were due to hepatocellular carcinoma. CONCLUSIONS Our center has a larger proportion of recipients transplanted by emergency status and MELD, similar MELD access, and less waiting list time, reflecting our wide policy of liver graft acceptance.

Abstract
INTRODUCTION There is a lack of information regarding outcomes after liver transplant in Latin America. OBJECTIVES This study sought to describe outcomes after liver transplant in adult patients from Argentina. METHODS We performed an ambispective cohort study of adult patients transplanted between June 2010 and October 2012 in 6 centers from Argentina. Only patients who survived after the first 48 hours postransplantation were included. Pretransplantation and posttransplantation data were collected. RESULTS A total of 200 patients were included in the study. Median age at time of transplant was 50 (interquartile range [IQR] 26 to 54) years. In total, 173 (86%) patients had cirrhosis, and the most frequent etiology in these patients was hepatitis C (32%). A total of 35 (17%) patients were transplanted with hepatocellular carcinoma. In patients with cirrhosis, the median Model for End-Stage Liver Disease (MELD) score at time of liver transplant was 25 (IQR 19 to 30). Median time on the waiting list for elective patients was 101 (IQR 27 to 295) days, and 3 (IQR 2 to 4) days for urgent patients. Almost 40% of the patients were readmitted during the first 6 months after liver transplant. Acute rejection occurred in 27% of the patients. Biliary and vascular complications were reported in 39 (19%) and 19 (9%) patients, respectively. Renal failure, diabetes, and dyslipidemia were present in 40 (26%), 87 (57%), and 77 (50%) at 2 years, respectively. CONCLUSIONS We believe the information contained in this article might be of value for reviewing current practices and developing local policies.

Abstract
BACKGROUND Hepatitis C virus (HCV)-related cirrhosis is a leading indication for liver transplantation (LT) worldwide. Access to effective HCV treatment is inequitable globally. We aimed to analyze whether the introduction of effective HCV treatment caused an impact in LT trends in a middle-income country. METHODS Cross-sectional analysis of all adult patients who were listed/received a LT in Argentina for HCV, alcohol-related liver disease (ALD), or autoimmune hepatitis/primary biliary cirrhosis (AIH/PBC) from 2007 to 2017. Joinpoint regression analysis was used to identify changes in the cumulative incidence rates in waiting list (WL) registration, WL mortality, and LT. RESULTS Liver transplantation WL for HCV increased significantly between 2007 and 2014, with an annual percentage change (APC) +7.8%, P = .01, followed by a downward slope from 2014 to 2017 with an APC -9.8%, P = .1. There were no significant changes in WL mortality. LT trends remained stable. LT for HCV without MELD exception points for HCC decreased (APC -6.6%, P = .01), whereas LT for HCV with HCC exception points increased (APC +11.1, P = .01) during the study period. CONCLUSION Waiting list and LT for HCV without HCC decreased, whereas LT for HCV and HCC increased; this may be related to selective antiviral treatment access for patients with advanced fibrosis.

Abstract
BACKGROUND AND AIMS Heterogeneous data has been reported regarding liver transplantation (LT) for hepatocellular carcinoma (HCC) in Latin America. We aimed to describe treatment during waiting list, survival and recurrence of HCC after LT in a multicenter study from Latin America. MATERIAL AND METHODS Patients with HCC diagnosed prior to transplant (cHCC) and incidentally found in the explanted liver (iHCC) were included. Imaging-explanted features were compared in cHCC (non-discordant if pre and post-LT were within Milan, discordant if pre-LT was within and post-LT exceeding Milan). RESULTS Overall, 435 patients with cHCC and 92 with iHCC were included. At listing, 81% and 91% of cHCC patients were within Milan and San Francisco criteria (UCSF), respectively. Five-year survival and recurrence rates for cHCC within Milan, exceeding Milan/within UCSF and beyond UCSF were 71% and 16%; 66% and 26%; 46% and 55%, respectively. Locoregional treatment prior to LT was performed in 39% of cHCC within Milan, in 53% beyond Milan/within UCSF and in 83% exceeding UCSF (p < 0.0001). This treatment difference was not observed according to AFP values (≤100, 44%; 101-1,000, 39%, and > 1,000 ng/mL 64%; p = 0.12). Discordant imaging-explanted data was observed in 29% of cHCC, showing lower survival HR 2.02 (CI 1.29; 3.15) and higher recurrence rates HR 2.34 when compared to AFP <100 ng/mL. Serum AFP > 1,000 ng/mL at listing was independently associated with a higher 5-year recurrence rate and a HR of 3.24 when compared to AFP <100 ng/mL. CONCLUSION Although overall results are comparable to other regions worldwide, pre-LT treatment not only considering imaging data but also AFP values should be contemplated during the next years.

Abstract
AIM To investigate any changing trends in the etiologies of hepatocellular carcinoma (HCC) in Argentina during the last years.
METHODS A longitudinal cohort study was conducted by 14 regional hospitals starting in 2009 through 2016. All adult patients with newly diagnosed HCC either with pathology or imaging criteria were included. Patients were classified as presenting non-alcoholic fatty liver disease (NAFLD) either by histology or clinically, provided that all other etiologies of liver disease were ruled out, fatty liver was present on abdominal ultrasound and alcohol consumption was excluded. Complete follow-up was assessed in all included subjects since the date of HCC diagnosis until death or last medical visit.
RESULTS A total of 708 consecutive adults with HCC were included. Six out of 14 hospitals were liver transplant centers (n = 484). The prevalence of diabetes mellitus was 27.7%. Overall, HCV was the main cause of liver disease related with HCC (37%) including cirrhotic and non-cirrhotic patients, followed by alcoholic liver disease 20.8%, NAFLD 11.4%, cryptogenic 9.6%, HBV 5.4% infection, cholestatic disease and autoimmune hepatitis 2.2%, and other causes 9.9%. A 6-fold increase in the percentage corresponding to NAFLD-HCC was detected when the starting year, i.e., 2009 was compared to the last one, i.e., 2015 (4.3% vs 25.6%; P < 0.0001). Accordingly, a higher prevalence of diabetes mellitus was present in NAFLD-HCC group 61.7% when compared to other than NAFLD-HCC 23.3% (P < 0.0001). Lower median AFP values at HCC diagnosis were observed between NAFLD-HCC and non-NAFLD groups (6.6 ng/mL vs 26 ng/mL; P = 0.02). Neither NAFLD nor other HCC etiologies were associated with higher mortality.
CONCLUSION The growing incidence of NAFLD-HCC documented in the United States and Europe is also observed in Argentina, a confirmation with important Public Health implications.

Abstract
OBJECTIVES: This study sought to assess the adherence of newly diagnosed hepatocellular carcinoma patients to the Barcelona Clinic Liver Cancer system treatment guidelines and to examine the impact of adherence on the survival of patients in different stages of the disease. METHODS: This study included all patients referred for the treatment of hepatocellular carcinoma between 2010 and 2012. Patients (n=364) were classified according to the Barcelona Clinic Liver Cancer guidelines. Deviations from the recommended guidelines were discussed, and treatment was determined by a multidisciplinary team. The overall survival curves were estimated with the Kaplan-Meier method and were compared using the log-rank test. RESULTS: The overall rate of adherence to the guidelines was 52%. The rate of adherence of patients in each scoring group varied as follows: stage 0, 33%; stage A, 45%; stage B, 78%; stage C, 35%; and stage D, 67%. In stage 0/A, adherent patients had a significantly better overall survival than non-adherent patients (hazard ratio=0.19, 95% confidence interval (CI): 0.09-0.42; p<0.001). Among the stage D patients, the overall survival rate was worse in adherent patients than in non-adherent patients (hazard ratio=4.0, 95% CI: 1.67-9.88; p<0.001), whereas no differences were observed in patients in stages B or C. CONCLUSIONS: The rate of adherence to the Barcelona Clinic Liver Cancer staging system in clinical practice varies according to clinical disease stage. Adherence to the recommended guidelines positively impacts survival, especially in patients with early-stage disease.

Abstract
BACKGROUND AND RATIONALE The post-Liver Transplant Quality of Life (pLTQ) questionnaire, developed in the United States, is a disease-targeted instrument designed to evaluate health-related quality of life (HRQoL) in liver transplant recipients. Our study sought to validate a version of the pLTQ for use in the Brazilian population. Translation and cross-cultural adaptation were carried out in accordance with international standard practices for questionnaire validation. Validity was measured by means of convergent validity (correlations between pLTQ domains and WHOQOL-Bref domains). Reliability was assessed by measurement of internal consistency (Cronbach's alpha coefficient), reproducibility (intraclass correlation coefficient), sensitivity to change (effect size), and floor and ceiling effects. RESULTS The study sample comprised 160 liver transplant recipients, with a mean age of 56.9 ± 10.4 years, treated at a tertiary hospital in Southern Brazil. The sample was largely male (62.5%), and the predominant indication for liver transplant was hepatocellular carcinoma (49.4%). Only two questionnaire items were modified during the translation and cross-cultural validation stage. The mean total pLTQ score was 5.58 ± 0.9, with < 20% floor/ceiling effect. Correlations between pLTQ and WHOQOL-Bref domains were acceptable (r = 0.37-0.40). For similar dimensions, the correlations between WHOQOL-Bref and pLTQ were statistically significant (p ≤ 0.001). Cronbach's alpha for the total score was 0.91 (95% CI 0.89-0.93), with a range of 0.51 to 0.77 across domains. Reproducibility was 0.90, and sensitivity to change was 0.84. CONCLUSION In conclusion, the Brazilian Portuguese versión of the pLTQ exhibited good psychometric performance, suggesting that it can be a useful tool in the Brazilian cultural context.

Abstract
INTRODUCTION Adherence to treatment is essential for a successful liver transplantation (LT) because LT requires information, abilities, and competencies of patients and family members. OBJECTIVES This study sought to identify whether the information received about the LT process was enough for either patients or family members who attended a liver transplant center in a school hospital. METHODS This was a transversal study using questionnaires to verify received information on LT. It included 50 patients on the waiting list for LT, 50 transplanted patients, and 50 family members. RESULTS There was a prevalence of men (82%) among patients, age range from 19 to 67 years (average: 46.87 ± 10.99), and of women (74%) among family members, age range from 18 to 80 years (average: 43.5 ± 11.77). The majority of subjects (88%) had a low education level. The most frequent etiology of hepatic cirrhosis was viral hepatitis associated with alcohol. A significant number of the listed and transplanted patients as well as all family members reported insufficient information about the process of the transplantation. The kind of insufficient information varied according to the period of treatment. The best way to obtain information, as reported by patients and family members, was a combination of oral and written information. CONCLUSIONS Our data show the need for improvement in the means of delivering information to patients and family members, and an explanatory manual was created from this study.

Identifying the Prognosis Factors in Death after Liver Transplantation via Adaptive LASSO in Iran. JOURNAL OF ENVIRONMENTAL AND PUBLIC HEALTH 2016; 2016:7620157. [PMID: 27648080 PMCID: PMC5014976 DOI: 10.1155/2016/7620157] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/28/2016] [Accepted: 08/07/2016] [Indexed: 12/28/2022]
Abstract
Despite the widespread use of liver transplantation as a routine therapy in liver diseases, the effective factors on its outcomes are still controversial. This study attempted to identify the most effective factors on death after liver transplantation. For this purpose, modified least absolute shrinkage and selection operator (LASSO), called Adaptive LASSO, was utilized. One of the best advantages of this method is considering high number of factors. Therefore, in a historical cohort study from 2008 to 2013, the clinical findings of 680 patients undergoing liver transplant surgery were considered. Ridge and Adaptive LASSO regression methods were then implemented to identify the most effective factors on death. To compare the performance of these two models, receiver operating characteristic (ROC) curve was used. According to the results, 12 factors in Ridge regression and 9 ones in Adaptive LASSO regression were significant. The area under the ROC curve (AUC) of Adaptive LASSO was equal to 89% (95% CI: 86%-91%), which was significantly greater than Ridge regression (64%, 95% CI: 61%-68%) (p < 0.001). As a conclusion, the significant factors and the performance criteria revealed the superiority of Adaptive LASSO method as a penalized model versus traditional regression model in the present study.

Abstract
Over 1700 liver transplantations (LTs) are performed annually in Brazil. In absolute terms, the country performs more LT surgeries than anywhere else in Latin America and is third worldwide. However, due to its increasing population and inadequate donor organ supply, the country averages 5-10 LTs per million population, far lower than required. There is a marked heterogeneity in organ donation and LT activity throughout the country. Access to LT in the underprivileged North, Midwest, and Northeast regions of Brazil is scarce. Major challenges for the future of LT in Brazil will be to increase organ donation and access to LT. The reduction of those geographical disparities in donation, organ procurement, and LT due to political and financial constraints is of utmost importance.

Abstract
Chronic hepatitis C remains one of the main causes of chronic liver disease worldwide and presents a variable natural history ranging from minimal changes to advanced fibrosis and cirrhosis and its complications, such as development of hepatocellular carcinoma. Approximately, 1.45 million people are estimated to be infected by HCV in Brazil representing a major public health issue. The aim of this paper was to review the epidemiology and management of chronic hepatitis C from a Brazilian perspective. The management of chronic hepatitis C has been challenged by the use of noninvasive methods to stage liver fibrosis as an alternative to liver biopsy and the high cost of new interferon-free antiviral treatments. Moreover, the need of cost-effectiveness analysis in hepatitis C and the recent changes in treatment protocols were discussed.

Abstract
Growing experience with the liver splitting technique and favorable results equivalent to those of whole liver transplant have led to wider application of split liver transplantation (SLT) for adult and pediatric recipients in the last decade. Conversely, SLT for two adult recipients remains a challenging surgical procedure and outcomes have yet to improve. Differences in organ shortages together with religious and ethical issues related to cadaveric organ donation have had an impact on the worldwide distribution of SLT. Despite technical refinements and a better understanding of the complex liver anatomy, SLT remains a technically and logistically demanding surgical procedure. This article reviews the surgical and clinical advances in this field of liver transplantation focusing on the role of SLT and the issues that may lead a further expansion of this complex surgical procedure.

Abstract
Donor age has become the dominant donor factor used to predict graft failure (GF) after liver transplantation (LT) in hepatitis C virus (HCV) recipients. The purpose of this study was to develop and validate a model of corrected donor age (CDA) for HCV LT recipients that transforms the risk of other donor factors into the scale of donor age. We analyzed all first LT recipients with HCV in the United Network for Organ Sharing (UNOS) registry from January 1998 to December 2007 (development cohort, n = 14,538) and January 2008 to December 2011 (validation cohort, n = 7502) using Cox regression, excluding early GF (<90 days from LT). Accuracy in predicting 1 year GF (death or repeat LT) was assessed with the net reclassification index (NRI). In the development cohort, after controlling for pre-LT recipient factors and geotemporal trends (UNOS region, LT year), the following donor factors were independent predictors of GF, all P < 0.05: donor age (hazard ratio [HR], 1.02/year), donation after cardiac death (DCD; HR, 1.31), diabetes (HR, 1.23), height < 160 cm (HR, 1.13), aspartate aminotransferase (AST) ≥ 120 U/L (HR, 1.10), female (HR, 0.94), cold ischemia time (CIT; HR, 1.02/hour), and non-African American (non-AA) donor-African American (AA) recipient (HR, 1.65). Transforming these risk factors into the donor age scale yielded the following: DCD = +16 years; diabetes = +12 years; height < 160 cm = +7 years; AST ≥ 120 U/L = +5 years; female = -4 years; and CIT = +1 year/hour > 8 hours and -1 year/hour < 8 hours. There was a large effect of donor-recipient race combinations: +29 years for non-AA donor and an AA recipient but only +5 years for an AA donor and an AA recipient, and -2 years for an AA donor and a non-AA recipient. In a validation cohort, CDA better classified risk of 1-year GF versus actual age (NRI, 4.9%; P = 0.009) and versus the donor risk index (9.0%, P < 0.001). The CDA, compared to actual donor age, provides an intuitive and superior estimation of graft quality for HCV-positive LT recipients because it incorporates additional factors that impact LT GF rates.

Abstract
Twenty years since the first cases were described, adult living donor liver transplantation (ALDLT) is now considered a valid option to expand the donor pool in view of the ongoing shortage of organs and the high waiting list mortality rate. Despite the rapid evolution and acceptance of this complex process of donation and transplantation in clinical practice, the indications, outcome, ethical considerations and quality and safety aspects continue to evolve based on new data from large cohort studies. This article reviews the surgical and clinical advances in the field of liver transplantation, focusing on technical refinements and discussing the issues that may lead to a further expansion of this complex surgical procedure and the role of ALDLT.
