Abstract
BACKGROUND Tissue engineering is considered as a promising tool for remodeling the native cells microenvironment. In the present study, the effect of alginate hydrogel and collagen microspheres integrated with extracellular matrix components were evaluated in the decrement of apoptosis in human pancreatic islets. MATERIALS/METHODS For three-dimensional culture, the islets were encapsulated in collagen microspheres, containing laminin and collagen IV and embedded in alginate scaffold for one week. After that the islets were examined in terms of viability, apoptosis, genes and proteins expression including BAX, BCL2, active caspase-3, and insulin. Moreover, the islets function was evaluated through glucose-induced insulin and C-peptide secretion assay. In order to evaluate the structure of the scaffolds and the morphology of the pancreatic islets in three-dimensional microenvironments, we performed scanning electron microscopy. RESULTS Our findings showed that the designed hydrogel scaffolds significantly improved the islets viability using the reduction of activated caspase-3 and TUNEL positive cells. CONCLUSIONS The reconstruction of the destructed matrix with alginate hydrogels and collagen microspheres might be an effective step to promote the culture of the islets.

Abstract
OBJECTIVES Estimation of liver fat among living donor candidates is necessary before living donor liver transplant. This study aimed to investigate the usefulness of the controlled attenuation parameter compared with liver biopsy for pretransplant estimation of hepatic steatosis in living liver donors. MATERIALS AND METHODS In this retrospective study, we included all individuals who underwent transient elastography with controlled attenuation parameter and ultrasonography-guided liver biopsy as a part of donor evaluations before living donor liver transplant. Clinical and laboratory data of living donor candidates were reviewed and collected. RESULTS Of 49 donor candidates included in this study, 21 (42.9%) had different degrees of hepatic macrosteatosis. Of the 21 donor candidates who had hepatic steatosis in liver biopsy, 13 individuals were diagnosed to have steatosis in transient elastography. Of the 28 donor candidates without hepatic steatosis in liver biopsy, 26 individuals showed no steatosis in transient elastography (odds ratio: 21.12; 95% CI, 3.91- 114.08; P < .001). Controlled attenuation parameter was useful in discriminating presence (P = .001) and grade of hepatic steatosis (P = .009) compared with liver biopsy with good sensitivity and specificity. CONCLUSIONS The controlled attenuation parameter is a noninvasive method for detection of hepatic steatosis in living donor candidates and can be used as an adjunct to liver biopsy for screening of living donor candidates before liver transplant.

Abstract
OBJECTIVE For the first time, we reported experiences with an intestinal rehabilitation unit (IRU) from a country without home parenteral nutrition (HPN). METHODS We included patients with a diagnosis of intestinal failure (IF) since the establishment of our IRU from February 2018 to February 2020. We further report on our protocols for management of enterocutaneous fistulas (ECFs), short-bowel syndrome (SBS), chronic intestinal pseudo-obstruction and motility disorders. RESULTS Among a total of 349 patients who have been admitted, 100 patients had IF and were included . Mean (SD) age of patients was 46.3 ± 16.1 years. Most common cause of IF was ECFs (32%), SBS (24%), and SBS + fistula (22%). Most common causes of SBS were mesenteric ischemia (63.3%) and repeated surgery (22.4%). Median (interquartile range [IQR]) duration of parenteral nutrition (PN) for patients was 32 (18-60) days. The most common reconstructive surgery performed was resection and anastomosis (75.4%), followed by serial transverse enteroplasty procedure (10.5%) and closure of ostoma (7%). Patients were hospitalized for a median (IQR) of 33 (17.5-61) days. Most common complications were sepsis (45%), catheter infections (43%), and catheter thrombosis (20%), respectively. At the final follow-up, 61% stopped receiving PN, 23% became candidates for transplantation, and 16% died. CONCLUSION Considering that most countries lack facilities for HPN, by establishing IRUs using specific treatment protocols and autologous gastrointestinal reconstruction techniques will provide a means to manage patients with IF, thus decreasing death rates and number of patients who require intestinal transplantations due to IF.

Abstract
Background Adrenal incidentalomas are often found during investigation for another tumor or unrelated problems. Except for adrenal myelolipoma (second most common primary adrenal incidentaloma following adrenocortical adenomas), adrenal lipomatous tumors are uncommon generally and are often described as case reports in the literature. Since the amount of fat is variable, without the help of advanced imaging techniques, some adrenal lipomatous tumors may be misdiagnosed before pathologic examination. Herein, we report a case of adrenal adenoma with myelolipomatous metaplasia that was excised as a periceliac mass in the setting of recurrent pancreatic cyst. Case report A 45-year-old Iranian woman with hypertension and end-stage renal disease presented with recurrence of a pancreatic cyst (previous pathologic report was mucinous cyst adenoma). During exploratory laparotomy, the mentioned pancreatic cyst was tightly attached to the stomach and jejunum. There was also a periceliac round rubbery lesion (firstly diagnosed by endoscopic ultrasound) that was excised for ruling out malignancy. Histologic examination of the periceliac mass was found to be adrenocortical adenoma with foci of myelolipomatous metaplasia. The pancreatic cyst histology was just a pseudocyst. Conclusion Our case highlights the significance of complete evaluation of incidental findings before surgical intervention, even in the setting of another primary tumor. Myelolipoma and myelolipomatous change (metaplasia) are two different entities. Although very similar as to pathogenesis, there are still some differences.

Abstract
BACKGROUND/PURPOSE Budd-Chiari syndrome (BCS) is a rare, life-threatening disease characterized by hepatic venous outflow obstruction. Liver transplantation (LT) is widely accepted as an effective therapeutic measure for irreversible liver failure due to BCS. There is debate on differences in the post LT course and complications in patients with BCS as compared to non-Budd-Chiari (NBC) patients. METHOD In this retrospective study, data on all patients who received a liver transplant for BCS at the Shiraz Organ Transplantation Center between January 1996 and September 2017 were reviewed and compared to data of a control group who had received liver transplants over the same period but due to other causes (NBC). RESULTS Out of 4225 patients who received liver transplants in the study period, 108 had BCS and an age- and gender-matched control group consisted of 108 NBC cases. The mean ± standard deviation (SD) of model for end-stage liver disease (MELD) scores were 19.1 ± 3 and 20 ± 3 for BCS and NBC groups, respectively (p = 0.33). One-, 3-, 5-, and 10-year survival rates in the BCS group were as follows: 82%, 78%, 76%, and 76% compared with the NBC rates of 83%, 83%, 83%, and 76%, respectively (p = 0.556). There was no difference between the two groups in complication rates after 6 months. In the later period, vascular thrombosis was more common in BCS. CONCLUSIONS Whole-organ LT from deceased donors in patients with BCS had comparable outcomes with LT due to other causes of end-stage liver disease. In most instances, these patients should receive lifelong anticoagulation.

Abstract
INTRODUCTION Continuous renal replacement therapy (CRRT) is an effective dialysis method in critically ill patients. Citrate and heparin are commonly used as anticoagulants to prevent premature circuit clotting. The aim of this study was to evaluate the safety and efficacy of using low dose systemic heparin while on CRRT in liver transplant recipients. METHODS We retrospectively evaluated and analyzed data from 29 liver transplant recipients undergoing CRRT in the postoperative course in this cross-sectional study. Numerous variables were recorded, such as coagulation parameters, duration of intensive care unit (ICU) stay, duration of dialysis, heparin dose, circuit life span, and anticoagulant complications. RESULTS Out of 29 recipients, there were 16 (55%) female and 13 (45%) male. All participants underwent whole organ liver transplantation with a median age of 45 years. Overall, 98 successful dialysis sessions were recorded in this study with a mean circuit life span of 36 hours. Mean ± SD duration of CRRT for each recipient was 4.8 ± 3.1 days. The median total dose of heparin used for each recipient was 25,000 units , and the median dose of heparin per-day for each recipient was about 3,300 units. There were no episodes of anticoagulant-related bleeding complications. Thirteen (13.2%) episodes of premature circuit clotting occurred. We found a significant association between the first dose and total dose of heparin usage with first postoperative INR and PTT level (P < .05, P < .05, P < .001, and P < .05). CONCLUSION In liver transplant recipients, low dose heparin during CRRT for patency of circuit is well tolerated.

Abstract
BACKGROUND Intestinal failure (IF) is a life-threatening medical condition. The management of IF in low- and middle-income countries without home parenteral nutrition (HPN) remains unclear. We recently established an intestinal rehabilitation unit (IRU) and aimed to provide our experience on the current management and outcomes of IF in Iran. METHODS In this cross-sectional case series, data were collected from an established database on IF in the Shiraz Transplant Center in Abu Ali Sina hospital, affiliated to Shiraz University of Medical Sciences, Iran from January 2018 to October 2018. RESULTS Overall, 30 patients with a mean age of 44.13 ± 10.32 years, which included 25 males, were recruited. Short bowel syndrome (SBS) (60%) and enterocutaneous fistulae (27%), as complication of previous surgeries, were the main causes of IF. The most common type of IF was type 3 (67 %). Mesenteric ischemia was the leading mechanism of IF (47%). Fifteen patients (50%) received autologous gastrointestinal reconstruction surgery (AGIRS), and two (7%) patients had serial transverse enteroplasty (STEP). At the end of follow-up, 15 patients recovered from IF (50%). The overall survival rate was 83.3%. CONCLUSION This series introduced the results of a multidisciplinary program for the treatment of IF in a middle-income country that lacks facilities for HPN. Our protocol of care, understanding the need for development of HPN, showed promising clinical outcomes.

Abstract
OBJECTIVES Liver transplant recipients are more susceptible to vancomycin-resistant enterococci colonization than healthy individuals. We investigated the prevalence of vancomycin-resistant enterococci colonization and its effect on the outcomes of liver transplant recipients. MATERIALS AND METHODS Patients who had undergone primary liver transplant at the Shiraz Organ Transplant Center from 2015 to 2017 were enrolled in this study. Demographic characteristics, laboratory test results, duration of stay in the intensive care unit, total duration of hospital stay, and clinical outcome data were extracted from the Shiraz Organ Transplant Center database. Posttransplant outcomes such as graft rejection, mortality, hospital stay, and kidney function tests were included for the first 90 days after transplant. RESULTS A total of 753 liver transplant recipients (470 males and 283 females) were included in this study. Vancomycin-resistant enterococci colonization was identified in 51 patients (6.8%) after transplant at the time of intensive care unit admission. Our study found no significant difference between outcomes for patients with vancomycin-resistant enterococci colonization and outcomes for patients without colonization, including graft rejection, mortality, hospital stay, and kidney function tests. CONCLUSIONS Our study revealed that asymptomatic vancomycin-resistant enterococci colonization in liver transplant patients has no adverse effect on the duration of posttransplant hospital stay, early mortality rate, graft rejection rate, or kidney function compared with noncolonized patients.

Abstract
BACKGROUND Kidney transplantation can increase survival and quality of life in patients with end-stage renal disease. In any allocation system, the crossmatch test plays an essential role in donor-recipient compatibility. OBJECTIVE In this study, we aim to test the benefits of a web-based program that captures HLA antibody analyses and provides a report to allow fast and accurate virtual crossmatches. METHODS One hundred potential recipients in the waiting list of renal transplants were selected. The included patients all had a complete HLA antibody profile. Also, 10 potential donors from previous kidney transplants (2020), with available HLA typing results for A, B, and DR locus, were also selected. A comparison was made between 100 recipients against ten potential donors, and virtual crossmatching (VXM) was performed by the web-based program and manually by an experienced immunologist. RESULTS The average time for a manual VXM was 30 minutes per patient, while the virtual cross web-based program took 5 minutes per patient. In 12% of the manual VXM cases, a secondary review of data improved final results. In two manual virtual crossmatches, the VXM results had errors in matching recipient antibodies with the donor HLA typing that could affect the final decision for transplantation. CONCLUSION In conclusion, a web-based VXM program that assesses HLA data can accurately perform a VXM with fewer human errors. It is especially true for highly sensitized candidates.

Abstract
BACKGROUND In this study, we report the epidemiology of COVID-19 among recipients of organ transplantation and evaluate associated factors with death. METHODS We screened 6969 patients who had organ transplantations in our center for COVID-19. Specific data on presentation, clinical course, treatment, and prognosis were acquired. RESULTS We found 85 patients (66 liver, 16 kidney, 2 kidney-pancreas, and 1 liver-kidney recipient) who acquired COVID-19. Most common symptoms included fever (48.2%), cough (41.2%), myalgia (41.2%), and fatigue (40%). Dyspnea developed in 33% of patients. Overall, one-third of patients had an oxygen saturation of below 90% on admission. Patients were hospitalized for a median (interquartile range) of 9 (5, 13.7) days and had a 33.9% intensive care unit admission rate. Overall, 17 patients (20%) died, which included 31.3% of patients with kidney transplantations and 18.2% of patients with liver transplantations. All 4 pediatric patients in our series died. In our univariate analysis among adults, rates of leukopenia (38.4% versus 13.2%; P = 0.04), low albumin levels (53.8% versus 10.2%; P = 0.001), and shorter duration between transplantation and COVID-19 (P = 0.02), were higher among patients who died. In our least absolute shrinkage and selection operator regression model, low albumin levels (OR, 4.48; 95% confidence interval, 1.16-17.27) were associated with higher risk of death. CONCLUSIONS This is the largest single-center report on abdominal transplantations and COVID-19. Liver and kidney transplant recipients have an increased risk of mortality compared with the general population due to COVID-19. More specifically, pediatric patients and those with low albumin levels are at higher risks of death due COVID-19.

Abstract
BACKGROUND Studies evaluating liver transplantation (LT) in hepatocellular carcinoma (HCC) in the Middle East have been scarce, mainly due to intricacy of this type of surgery. OBJECTIVE In here we report our experiences with LT among patients with HCC cirrhosis.Methods: All patients who underwent LT with primary diagnosis of HCC older than 18 years old, during 2004 to 2019, were initially included in our study. RESULTS Overall, 124 patients entered our study, among which majority were males (86.3%). Mean (SD) age of patients was 53.1±10.6 years old. Most common underlying liver diseases were HBV (55.6%) and HCV infections (12.1%). Mean MELD score of patients was 18±5.5. Child-Pugh score of most patients was class B (50%). Mean (SD) duration of hospitalization was 12.1±3.5 days. Patients were followed for a median of 32 (9, 62) months. The most common causes of death were recurrence of HCC (47.7%) and sepsis (34.1%). Median (IQR) duration to recurrence and death were 18 (4, 34) months and 17.5 (5.7, 44.5) months, respectively. One-year survival (89%, 86.4%, and 63.2%, respectively) (p=0.011) and one-year DFS (89%, 86.4%, and 57.9%, respectively) (p=0.001) was significant different between those who were selected based on the Milan, UCSF and extended criteria. CONCLUSION Our study provides valuable experiences on LT and HCC from one of the largest LT centers in the world. Accordingly, we found that the Milan criterion provides the best survival compared to the UCSF and our extended criteria for patient selection.

Abstract
BACKGROUND Ischemia-reperfusion injury during transplantation can cause post-operative graft dysfunction. OBJECTIVE To assess the efficacy of N-acetylcysteine in preventing hepatic ischemia-reperfusion injury and post-transplant outcomes. METHODS In this retrospective study on pediatrics undergoing living-donor (from one of their parents) liver transplantation, N-acetylcysteine was administered to one group (n=20) after induction in the donors until graft harvest, and in the recipients during implantation, which was maintained for 19 hours. The second group (n=20) did not receive NAC. Early allograft dysfunction was determined in the presence of alanine aminotransferase or aspartate aminotransferase ≥2000 IU/L and bilirubin ≥10 mg/dL within the first 7 days, and an international normalized ratio ≥1.6 on day 7. Data were collected from a retrospectively maintained database. RESULTS The incidence of post-reperfusion syndrome was lower in N-acetylcysteine group compared with the other group (5% vs. 30%, p=0.037). Serum creatinine level was significantly (p=0.04) different in the N-acetylcysteine group during the second post-operative week (0.14 vs. 0.15 mg/dL). There was no significant difference in the incidence of early allograft dysfunction (21% vs. 14%, p=0.327), and the survival rate (p=0.409). CONCLUSION Peri-operative infusion of N-acetylcysteine in both donor and recipient would effectively prevent post-reperfusion syndrome and renal insufficiency. However, it might not affect the early allograft dysfunction, ICU stay, and mortality. NAC increases the chance of re-operation due to non-surgical bleeding in the first post-operative day.

Abstract
OBJECTIVES Investigating the survival features, and determinants of treatment and stage at presentation in Iran. METHODS 461 patients with pancreatic ductal adenocarcinoma (PC) were prospectively enrolled from Shariati hospital, Tehran, Iran, between 2011-2018. All patients underwent endoscopic ultrasonography, computed tomography scanning, and physical examination. Validated questionnaire was completed for the participants and all were actively followed on monthly basis. RESULTS Median survival time was 6.5 months, and 1-, and 5-year survival rates were 26.2%, and 1.5%. Patients who were older (p<0.001), illiterate (p = 0.004), unmarried (p = 0.003), rural inhabitant (p = 0.013), opium user (p = 0.039), and had lower body mass index (BMI) (p = 0.002) had lower overall survival. Tumors located in the head of pancreas were more commonly diagnosed at lower stages (p<0.001). Only 10.4% of patients underwent surgery who were more commonly educated (p<0.001), married (p = 0.005), had a tumor located in the head of pancreas (p = 0.016), and were diagnosed at lower stages (p<0.001). After adjustment for potential confounders and risk factors, rural inhabitance (HR: 1.33 (95% CI: 1.01-1.74)), having more symptoms (HR for each increasing symptom: 1.06 (1.02-1.11)), using opium (HR: 1.51 (1.04-2.20)), having a tumor located in the body of pancreas (HR: 1.33 (1.02-1.75)), and having an advanced tumor stage (HR: 2.07 (1.34-3.19)) remained significantly associated with increased risk of mortality. After the adjusting for potential confounders, we did not find significant relationships between smoking, alcohol intake, and BMI with the risk of death among patients with pancreatic cancer. CONCLUSIONS Iranian patients with PC have very poor long-term survival. Besides tumor's stage and location, socioeconomic disparities could affect the probabilities of receiving treatment and/or survival in these patients. Opium use is an independent risk factor for mortality among PC patients in Iran.

Abstract
Background Immunosuppressed patients, including individuals with organ transplantation, have been among susceptible groups with regard to COVID-19, on the other hand pediatric patients more commonly undergo a mild clinical course after acquiring COVID-19. To the best of the authors knowledge, to this date very little data exists on COVID-19 in a pediatric patient with liver transplantation. Case presentation We report a three year-old boy who had liver transplantation at 18 months old. He was admitted due to dyspnea with impression of acute respiratory distress syndrome and was then transferred to the intensive care unit. Chest X-ray at admission showed bilateral infiltration. Vancomycin, meropenem, azithromycin, voriconazole and co-trimoxazole were started from the first day of admission. On day 4 of admission, with suspicion of COVID-19, hydroxychloroquine, lopinavir/ritonavir and oseltamivir were added to the antibiotic regimen. PCR was positive for COVID-19. The patient developed multi-organ failure and died on day 6 of admission. Conclusions For pediatric patients with organ transplantations, extreme caution should be taken, to limit and prevent their contact with COVID-19 during the outbreak, as these patients are highly susceptible to severe forms of the disease.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is frequently seen among non-obese overweight individuals and lean subjects (those with normal body mass index). This study aimed to investigate prevalence and risk factors of biopsy proven NAFLD in a cluster of healthy non-obese and lean individuals. METHODS AND MATERIALS In a retrospective study, adult (>18 years) apparently healthy individuals who had donated liver to pediatric patients between July 2012 and October 2018 were included. Non-obese and lean individuals were defined as BMI<30kg/m2 and BMI<25kg/m2, respectively. RESULTS Totally 310 patients were included. Seventy-six individuals (24.5%) had NAFL and 30 patients (9.67%) had non-alcoholic steatohepatitis (NASH) among non-obese population. In multivariate regression analysis, only higher BMI was marginally associated with NASH in non-obese compared to those without NASH (Odds ratio: 2.52, 95% CI: 0.097-6.54; P=0.05). Totally, 246 individuals were lean. 55 individuals (22.3%) had NAFL and 20 individuals (8.2%) had NASH in their liver biopsies. In univariate analysis, serum triglyceride, cholesterol, LDL, ALT, alkaline phosphatase and uric acid were associated with NAFL among lean individuals (P<0.05). In regression analysis, serum uric acid was associated with NAFL (Odds ratio: 1.70, 95% CI: 1.18-2.45; P=0.004) and NASH in lean individuals (Odds ratio: 1.98, 95% CI: 1.27-3.10; P=0.003). CONCLUSION NAFLD/NASH is prevalent even in a healthy lean population when evaluated by liver biopsy. Higher BMI and serum uric acid were two major risks of NAFLD/NASH in non-obese and lean individuals.

Abstract
Background To this date little information exists on the effects, clinical course and outcome of the COVID-19 among patients undergoing transplantation. Case presentation A 35 year old male referred with loss of sense of smell and taste after having close contact with his brother who was diagnosed with COVID-19 five days prior to his symptoms. The patient had undergone liver transplantation 3 years prior to his referral due to primary sclerosing cholangitis in association with ulcerative colitis and was using immunosuppressive medications. The patient referred to a local physician with mild symptoms of fatigue, cough, myalgia, dizziness, and nausea/vomiting with a fear of contracting the disease. Except for a CRP of 32 his other blood tests were normal. After 3 days of hospital admission the patient was discharged with a good condition. His brother had developed fever, chills, headache, mild dyspnea and an objective loss of sense of smell and taste and was sent home and advised to self-quarantine. Both patients had CT scans in favor of COVID-19. Conclusion Our patient who had liver transplantation and COVID-19 did not present more severe symptoms compared to his counterpart without liver transplantation and did not need to be hospitalized or be given antiviral drugs for COVID-19.

Abstract
BACKGROUND AND AIM Cirrhosis is a major public health problem worldwide. The prevalence of cirrhosis is various in different geographical regions. The aim of the present study was to determine the distribution of the etiologies of cirrhosis and their proportional changes through recent 11 years in Iran. METHODS In this retrospective, observational study, the data of cirrhotic patients who have been listed for liver transplantation in the Namazi Transplant Center (Shiraz, Iran) between January 2006 and December 2016 were analyzed. Demographic and clinical data of the patients including model for end-stage liver disease score, year of registration, and the etiologic diagnosis for each patient were retrieved. RESULTS The ratio of males to females was the highest (2.6:1) in patients with age over 50 years. Of 4891 patients, hepatitis B virus cirrhosis had the highest frequency (23.53%) and alcoholic cirrhosis had the lowest frequency (1.70%). The percentages of waiting list patients with hepatitis B virus (34.48%-17.48%) (P < 0.001), autoimmune hepatitis (12.64%-8.50%) (P = 0.037), and alcoholic cirrhosis (2.30%-1.10%) were decreased (P = 0.008) and the percentages of waiting list patients with cholestatic (12.64%-25.20%) and nonalcoholic steatohepatitis cirrhosis (0.77%-8.82%) were increased over 11 years (both P < 0.001). Hepatitis B virus and autoimmune hepatitis cirrhosis were the most prevalent in male and female patients, respectively. CONCLUSION The results of the present study showed an increase in the frequency of cholestasis and nonalcoholic steatohepatitis cirrhosis and therefore it should be considered in the health policy implementation.

Abstract
BACKGROUND AND AIMS Successful islet transplantation as a promising treatment of diabetes type 1 is threatened with the loss of islets during the pre-transplant culture due to hypoxia and oxidative stress-induced apoptosis. Therefore, optimization of culture in order to preserve the islets is a critical point. In this study, we investigated the effect of resveratrol, as a cytoprotective agent, on the cultured human islets. METHODS AND RESULTS Isolated islets were treated with different concentrations of resveratrol for 24 and 72 h. Islets' viability, apoptosis, apoptosis markers, and insulin and C-peptide secretion, along with the production of reactive oxygen species (ROS), hypoxia inducible factor 1 alpha (HIF-1α), and its target genes in the islets were investigated. Our findings showed that the islets were exposed to hypoxia and oxidative stress after isolation and during culture. This insult induced apoptosis and decreased viability during 72 h. The presence of resveratrol significantly attenuated HIF-1α and ROS production, reduced apoptosis, promoted the VEGF secretion, and increased the insulin and C-peptide secretion. In this regard, resveratrol improved the islet's survival and function in the culture period. CONCLUSIONS Using resveratrol can attenuate the stressful condition for the islets in the pre-transplant culture and subsequently ameliorate their viability and functionality that lead to successful outcome after clinical transplantation.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) may occur in liver transplant recipients. This study aimed to investigate the prevalence and risk factors of NAFLD after liver transplantation in patients with NASH and cryptogenic cirrhosis, focusing on the impact of graft steatosis. METHODS Patients with NASH and cryptogenic cirrhosis who had undergone liver transplantation in Shiraz transplant center between March 2010 and March 2017 were included. NAFLD was diagnosed after liver transplantation using ultrasonography and transient elastography. RESULTS 73 patients with NASH and 389 with cryptogenic cirrhosis were included. NAFLD was diagnosed in 33 patients (56.9%) in NASH group and 96 patients (26.7%) in cryptogenic group (OR: 3.61; CI: 2.04-6.39; P-Value < 0.001), using ultrasound. Obesity and post-transplant hyperlipidemia were independent predictors of NAFLD after liver transplantation (P < 0.05). NAFLD was diagnosed in 32.9% of patients with graft macrosteatosis compared to 29.9% in patients without graft macrosteatosis (OR: 1.51; 95%CI: 0.755-1.753). 28% of the patients with macrosteatosis ≥30% had NAFLD after liver transplantation compared to 31.4% with macrosteatosis <30% (OR: 1.175; 95% CI: 0.346-2.091). CONCLUSION Liver graft steatosis before transplantation was not associated with the occurrence of NAFLD after liver transplantation.

Abstract
Purpose In this study, we aimed to compare the efficacy of combined ceftizoxime with ampicillin-sulbactam versus combined gentamicin with ampicillin-sulbactam as prophylactic antibiotic regimen in preventing early bacterial PTIs in liver TX recipients at a referral center. Patients and methods All patients older than 18 years who had undergone liver TX at Abu-Ali Sina transplantation center in Shiraz, Iran from July 2018 to April 2019 were included in this study. In a single-blinded manner, the participants randomly received either combined intravenous ceftizoxime plus ampicillin-sulbactam (ceftizoxime group) or gentamicin plus ampicillin-sulbactam (gentamicin group) as prophylactic antibiotic regimen before the incision of the surgery, which was continued for 48 hrs after liver Tx. The rate and type of bacterial infections, length of hospital and intensive care unit (ICU) stay, mortality rate, and kidney function were assessed during 1 month following liver TX in the two groups. Results Two hundred and thirty patients were divided into two groups. One patient in the gentamicin group and five in the ceftizoxime group were excluded due to emergency exploratory laparotomy within the first 3 days after transplantation. The rate of bacterial infections during the first month after transplantation was 25.4%. This rate was significantly lower in the gentamicin group (13.16%) in comparison to the ceftizoxime group (38.18%) (P value<0.01), based on the univariate logistic regression analysis. Length of ICU and hospital stay and also mortality rate were significantly lower in the gentamicin group (P value <0.01). There was no significant difference regarding kidney function between the two groups (P value = 0.16). Conclusion Our results suggested that gentamicin can be considered as a promising agent in prophylactic antibiotic regimen for patients undergoing liver TX. Trial registration The study was registered at the Iranian Registry of Clinical Trials (IRCT20120731010453N2; http://www.irct.ir/).

Abstract
Background Ex situ liver resection and autotransplantation is among the most advanced techniques which has been introduced in recent years. Case presentation A 24-year-old male referred with chief complaints of abdominal pain, nausea, and vomiting from 1 month prior to admission. Computed tomography showed a large liver mass in the left lobe of the liver with involvement of retrohepatic inferior vena cava (IVC), in favor of hepatocellular carcinoma. After hepatectomy, the common bile duct was completely removed. A 4-cm Dacron graft was anastomosed to the inferior and top of the IVC. A temporary portocaval shunt was placed, and ex situ resection of the left lobe of the liver was done. Remnant of the liver was implanted. Reconstruction of the bile duct was done using a Roux-en-Y technique, and autotransplantation of the liver was then completed. During a 4-year follow-up, the patient had no complaints and is in good conditions. Conclusion With appropriate consideration of patients, despite surgical complexities, ex situ resection of unresectable HCC can provide excellent prognosis.

Abstract
BACKGROUND Probable effects of living donor liver transplantation on the wellbeing of the donor and psychological difficulties are necessary to be understood. OBJECTIVE To assess the quality of life of living donors after liver donation. METHODS 140 living donors who underwent hepatectomy between 2012 and July 2015 were enrolled in this study. Donors were asked to complete the Short Form 36-question Health Survey (SF-36) through face to face or by telephone interview. RESULTS The mean±SD age of donors at transplantation was 32.1±7.3 years; 83 (59.3%) of donors were female. 134 (95.7%) were married. The mean±SD BMI was 23.8±3.5 (kg/m2). "Mother-to-child" was the most frequent relationship (n=79, 56.4%). 22 (15.7%) complications were reported by participants. The mean±SD score of Physical Component Summary and Mental Component Summary were 48.8±14.6 and 50.1±6.9, respectively. CONCLUSION Most living donors sustain a near average quality of life post-donation. It seems that living donation does not negatively affect the quality of life.
