Abstract
BACKGROUND Over 16 000 children under the age of 15 died worldwide in 2017 because of liver disease. Pediatric liver transplantation (PLT) is currently the standard of care for these patients. The aim of this study is to describe global PLT activity and identify variations between regions. METHODS A survey was conducted from May 2018 to August 2019 to determine the current state of PLT. Transplant centers were categorized into quintile categories according to the year they performed their first PLT. Countries were classified according to gross national income per capita. RESULTS One hundred eight programs from 38 countries were included (68% response rate). 10 619 PLTs were performed within the last 5 y. High-income countries performed 4992 (46.4%) PLT, followed by upper-middle- (4704 [44·3%]) and lower-middle (993 [9·4%])-income countries. The most frequently used type of grafts worldwide are living donor grafts. A higher proportion of lower-middle-income countries (68·7%) performed ≥25 living donor liver transplants over the last 5 y compared to high-income countries (36%; P = 0.019). A greater proportion of programs from high-income countries have performed ≥25 whole liver transplants (52.4% versus 6.2%; P = 0.001) and ≥25 split/reduced liver transplants (53.2% versus 6.2%; P < 0.001) compared to lower-middle-income countries. CONCLUSIONS This study represents, to our knowledge, the most geographically comprehensive report on PLT activity and a first step toward global collaboration and data sharing for the greater good of children with liver disease; it is imperative that these centers share the lead in PLT.

Abstract
BACKGROUND Living donor liver transplantation is a safe alternative for patients on a liver transplant list. Donor evaluation goes beyond physical variables to include social, emotional, and ethical aspects. The role of pre-donation sociopsychological evaluation of the donor candidate is as important to the success of the procedure as is the medical assessment. Success implies recovery from the operation and prompt engagement in pre-transplant professional and social activities, without leading to psychological or physical distress. Psychological profiling of potential living liver donors (PLLD) and evaluation of quality of life (QOL) can influence outcomes.
AIM To evaluate the socio-demographics and psychological aspects (QOL, depression, and anxiety) of PLLD for pediatric liver transplantation in a cohort of 250 patients.
METHODS This was a retrospective cohort study of 250 PLLD who underwent psychological pre-donation evaluation between 2015 and 2019. All the recipients were children. The Beck anxiety inventory, Beck depression inventory, and 36-item short-form health survey (SF-36) scores were used to evaluate anxiety (Beck anxiety inventory), depression (Beck depression inventory), and QOL, respectively.
RESULTS A total of 250 PLLD were evaluated. Most of them were women (54.4%), and the mean age was 29.2 ± 7.2 years. A total of 120 (48.8%) PLLD were employed at the time of evaluation for donation; however, most had low income (57% earned < 2 times the minimum wage). A total of 110 patients (44%) did not finish the donation process, and 247 PLLD answered a questionnaire to evaluate depression, anxiety, and QOL (SF-36). Prevalence of depression was of 5.2% and anxiety 3.6%. Although most of the PLLD were optimistic regarding the donation process and never had doubts about becoming a donor, some traces of ambivalence were observed: 46% of the respondents said they would feel relieved if a deceased donor became available.
CONCLUSION PLLD had a low prevalence of anxiety and depression. The foundation for effective and satisfactory results can be found in the pre-transplantation process, during which evaluations must follow rigorous criteria to mitigate potential harm in the future. Pre-donation psychological evaluation plays a predictive role in post-donation emotional responses and mental health issues. The impact of such findings on the donation process and outcomes needs to be further investigated.

Abstract
BACKGROUND The impact of perioperative blood transfusion on short- and long-term outcomes in pediatric living donor liver transplantation (PLDLT) must still be ascertained, mainly among young children. Clinical and surgical postoperative complications related to perioperative blood transfusion are well described up to three months after adult liver transplantation.
AIM To determine whether transfusion is associated with early and late postoperative complications and mortality in small patients undergoing PLDLT.
METHODS We evaluated the effects of perioperative transfusion on postoperative complications in recipients up to 20 kg of body weight, submitted to PLDLT. A total of 240 patients were retrospectively allocated into two groups according to postoperative complications: Minor complications (n = 109) and major complications (n = 131). Multiple logistic regression analysis identified the volume of perioperative packed red blood cells (RBC) transfusion as the only independent risk factor for major postoperative complications. The receiver operating characteristic curve was drawn to identify the optimal volume of the perioperative RBC transfusion related to the presence of major postoperative complications, defining a cutoff point of 27.5 mL/kg. Subsequently, patients were reallocated to a low-volume transfusion group (LTr; n = 103, RBC ≤ 27.5 mL/kg) and a high-volume transfusion group (HTr; n = 137, RBC > 27.5 mL/kg) so that the outcome could be analyzed.
RESULTS High-volume transfusion was associated with an increased number of major complications and mortality during hospitalization up to a 10-year follow-up period. During a short-term period, the HTr showed an increase in major infectious, cardiovascular, respiratory, and bleeding complications, with a decrease in rejection complications compared to the LTr. Over a long-term period, the HTr showed an increase in major infectious, cardiovascular, respiratory, and minor neoplastic complications, with a decrease in rejection complications. Additionally, Cox hazard regression found that high-volume RBC transfusion increased the mortality risk by 3.031-fold compared to low-volume transfusion. The Kaplan-Meier survival curves of the studied groups were compared using log-rank tests and the analysis showed significantly decreased graft survival, but with no impact in patient survival related to major complications. On the other hand, there was a significant decrease in both graft and patient survival, with high-volume RBC transfusion.
CONCLUSION Transfusion of RBC volume higher than 27.5 mL/kg during the perioperative period is associated with a significant increase in short- and long-term postoperative morbidity and mortality after PLDLT.

Abstract
Portal vein thrombosis (PVT) may occur at any time following liver transplantation. We describe our experience with portal vein recanalization in cases of thrombosis after liver transplantation. Twenty-eight children (5%) out of 566 liver transplant recipients underwent portal vein recanalization using a transmesenteric approach. All children received left hepatic segments, developed PVT, and had symptoms or signs of portal hypertension. Portal vein recanalization was performed via the transmesenteric route in all cases. Twenty-two (78.6%) patients underwent successful recanalization and stent placement. They received oral anticoagulants after the procedure, and clinical symptoms subsided. Symptoms recurred due to portal vein restenosis/thrombosis in seven patients. On an intention-to-treat basis, the success rate of the proposed treatment was 60.7%. Only 17 out of 28 children with posttransplant chronic PVT retained stent patency (primary + assisted) at the end of the study period. In cases of portal vein obstruction, the transmesenteric approach via minilaparotomy is technically feasible with good clinical and hemodynamic results. It is an alternative procedure to reestablish the portal flow to the liver graft that can be performed in selected cases and a therapeutic addition to other treatment strategies currently used to treat chronic PVT.

Abstract
Liver transplant is considered to be the last-resort treatment approach for pediatric patients with end-stage liver disease. Despite the remarkable advance in survival rates, liver transplant remains an intricate surgery with significant morbidity and mortality. Early diagnosis of complications is crucial for patient survival but is challenging given the lack of specificity in clinical presentation. Knowledge of the liver and vascular anatomy of the donor and the recipient or recipients before surgery is also important to avoid complications. In this framework, radiologists play a pivotal role on the multidisciplinary team in both pre- and postoperative scenarios by providing a road map to guide the surgery and by assisting in diagnosis of complications. The most common complications after liver transplant are (a) vascular, including the hepatic artery, portal vein, hepatic veins, and inferior vena cava; (b) biliary; (c) parenchymal; (d) perihepatic; and (e) neoplastic. The authors review surgical techniques, the role of each imaging modality, normal posttransplant imaging features, types of complications after liver transplant, and information required in the radiology report that is critical to patient care. They present an algorithm for an imaging approach for pediatric patients after liver transplant and describe key points that should be included in radiologic reports in the pre- and postoperative settings.

Abstract
Re-LT is the only recourse for patients with liver graft failure. However, survival rates after re-LT are lower than those of primary transplants. Few reports are available regarding re-LT with LDs in children. The objective of this study was to describe our cohort of patients retransplanted with LD and emphasize the technical aspects of a re-LT with LD. This is a retrospective report of a series of 18 children (<18 yr old) submitted to 20 re-LT from January 1997 to December 2013 at Hospital Sirio-Libanes and Hospital AC Camargo Cancer Center. The one- and five-yr survival for patients retransplanted with LD was 70.6% and 58.6%. Little technical modifications from a regular LD primary transplant were needed in patients retransplanted with LD. Seven (38.8%) patients presented vascular complications following re-LT and three presented biliary complications (16.6%). In conclusion, a re-LT with LD is an acceptable alternative for children who experience liver graft failure and it does not compromise the donor pool. Further experience with re-LT with LD may support this therapy.

Abstract
LT started in LA in 1968, and pediatric LT records are available starting in the 1990s. Currently, eight countries perform pediatric LT in LA. Registries by national organizations fail to report robust data on pediatric LT. The aim of this paper was to report on the pediatric LT activity in LA. Data were gathered retrospectively through information available in the national registries websites and from local centers. Of the eight countries that report pediatric LT activity, Brazil, Argentina, Mexico, and Colombia have adequate registries of the numbers of LT performed. These countries concentrate most of the activity for pediatric LT. A total of 4593 pediatric LT were reported in LA. Websites for national organizations do not provide open data on post-transplant survival rates or waiting list mortality. The information herein is based on reports by local centers. Overall, survival from select centers is similar to that reported on North American and European registries, between 80 and 90% in the first year post-transplant. In conclusion, pediatric LT activity is growing in LA, especially in Brazil and Argentina. However, the lack of an appropriate LA registry restricts the assessment of quality and therefore restricts interventions aimed at quality improvements in different regions.

Abstract
The expanded indications of partial grafts in pediatric liver transplantation have reduced waiting list mortality. However, a higher morbidity is observed, including an increased rate of biliary complications (BCs). Factors such as the type of graft, the preservation methods applied, the donor characteristics, the type of biliary reconstruction, and the number of bile ducts in the liver graft influences the occurrence of these complications. Bile leaks and strictures comprise the majority of post-transplant BCs. Biliary strictures require a high grade of suspicion, and because most children have a bileo-enteric anastomosis, its diagnosis and management rely on percutaneous hepatic cholangiography and percutaneous biliary interventions (PBI). The success rates with PBI range from 70% to 90%. Surgery is reserved for patients who have failed PBI. BCs in children after liver transplantation have a prolonged treatment and are associated with a longer length of stay and higher hospital costs. However, with early diagnosis and aggressive treatment, patient and graft survival are not significantly compromised.

Abstract
The vascular anomalies encountered in patients with biliary atresia associated with polysplenia syndrome and situs inversus (SI) demand technical refinements when liver transplantation is being performed. The available data describing the technique used in living donor liver transplantation (LDLT) in this population are limited; the short vascular stumps of the donor's liver can impart additional technical difficulties during vascular reconstruction. Here we describe our experience with 9 children with biliary atresia and SI who underwent LDLT. In our series, the retrohepatic vena cava was absent for 7 patients, 7 had a preduodenal portal vein (PV), and 4 had a variant arterial anatomy. The donor's left hepatic vein was anastomosed to the confluence of the recipient's 3 hepatic veins in 7 patients. Vascular grafts were used for PV reconstruction in 3 cases. A left lateral segment graft was used in all but 1 patient who needed a graft reduction. All grafts were placed in the upper left abdomen. There were no vascular complications after transplantation. All patients were alive and well at a median follow-up of 55 months. In conclusion, LDLT can be successfully performed in pediatric patients with SI. Complex vascular anomalies associated with the use of partial liver grafts obtained from living donors are not associated with an increased occurrence of vascular complications.

Abstract
Chronic allograft nephropathy (CAN) represents progressive deterioration of renal allograft function with fibroinflammatory changes. CAN, recently reclassified as interstitial fibrosis (IF) and tubular atrophy (TA) with no known specific etiology, is a major cause of late renal allograft loss and remains a significant deleterious factor of successful renal transplantation. Carbon monoxide (CO), an effector byproduct of heme oxygenase pathway, is known to have potent anti-inflammatory and antifibrotic functions. We hypothesized that inhaled CO would inhibit fibroinflammatory process of CAN and restore renal allograft function, even when the treatment was initiated after CAN was established. Lewis rat kidney grafts were orthotopically transplanted into binephrectomized allogenic Brown Norway rats under brief tacrolimus (0.5 mg/kg im, days 0-6). At day 60, CO (20 ppm) inhalation was initiated to recipients and continued until day 150 or animal death. Development of CAN was confirmed at day 60 with decreased creatinine clearance (CCr), significant proteinuria, and histopathological findings of TA, IF, and intimal arteritis. Air-treated control recipients continued to deteriorate with further declines of CCr and increases of urinary protein excretion and died with a median survival of 82 days. In contrast, progression of CAN was decelerated when recipients received CO on days 60-150, showing markedly improved graft histopathology, restored renal function, and improved recipient survival to a median of >150 days. CO significantly reduced intragraft mRNA levels for IFN-gamma and TNF-alpha at day 90. Expression of profibrotic TGF-beta/Smad was significantly suppressed with CO, together with downregulation of ERK-MAPK pathways. Continuous CO (20 ppm) treatment for days 0-30, days 30-60, or days 0-90, or daily 1-h CO (250 ppm) treatment for days 0-90, also showed efficacy in inhibiting CAN. The study demonstrates that CO is able to inhibit progression of fibroinflammatory process of CAN, restore renal allograft function, and improve survival even when the treatment is started after CAN is diagnosed.
