Abstract
Delayed gastric emptying (DGE) is a common complication of liver transplantation. This study aimed to clarify the efficacy and safety of the application of an adhesion barrier for preventing DGE in living-donor liver transplantation. This retrospective study included 453 patients who underwent living-donor liver transplantation using a right lobe graft between January 2018 and August 2019, and the incidence of postoperative DGE and complications was compared between patients in whom adhesion barrier was used (n=179 patients) and those in whom adhesion barrier was not used (n=274 patients). We performed 1:1 propensity score matching between the 2 groups, and 179 patients were included in each group. DGE was defined according to the International Study Group for Pancreatic Surgery classification. The use of adhesion barrier was significantly associated with a lower overall incidence of postoperative DGE in liver transplantation (30.7 vs. 17.9%; p =0.002), including grades A (16.8 vs. 9.5%; p =0.03), B (7.3 vs. 3.4%; p =0.08), and C (6.6 vs. 5.5%; p =0.50). After propensity score matching, similar results were observed for the overall incidence of DGE (29.6 vs. 17.9%; p =0.009), including grades A (16.8 vs. 9.5%; p =0.04), B (6.7 vs. 3.4%; p =0.15), and C (6.1 vs. 5.0%; p =0.65). Univariate and multivariate analyses showed a significant correlation between the use of adhesion barrier and a low incidence of DGE. There were no statistically significant differences in postoperative complications between the 2 groups. The application of an adhesion barrier could be a safe and feasible method to reduce the incidence of postoperative DGE in living-donor liver transplantation.

Abstract
Identifying factors associated with persistent pain after breast cancer surgery may facilitate risk stratification and individualised management. Single-population studies have limited generalisability as socio-economic and genetic factors contribute to persistent pain development. Therefore, this prospective multicentre cohort study aimed to develop a predictive model from a sample of Asian and American women. We enrolled women undergoing elective breast cancer surgery at KK Women's and Children's Hospital and Duke University Medical Center. Pre-operative patient and clinical characteristics and EQ-5D-3L health status were recorded. Pain catastrophising scale; central sensitisation inventory; coping strategies questionnaire-revised; brief symptom inventory-18; perceived stress scale; mechanical temporal summation; and pressure-pain threshold assessments were performed. Persistent pain was defined as pain score ≥ 3 or pain affecting activities of daily living 4 months after surgery. Univariate associations were generated using generalised estimating equations. Enrolment site was forced into the multivariable model, and risk factors with p < 0.2 in univariate analyses were considered for backwards selection. Of 210 patients, 135 (64.3%) developed persistent pain. The multivariable model attained AUC = 0.807, with five independent associations: age (OR 0.85 95%CI 0.74-0.98 per 5 years); diabetes (OR 4.68, 95%CI 1.03-21.22); pre-operative pain score at sites other than the breast (OR 1.48, 95%CI 1.11-1.96); previous mastitis (OR 4.90, 95%CI 1.31-18.34); and perceived stress scale (OR 1.35, 95%CI 1.01-1.80 per 5 points), after adjusting for: enrolment site; pre-operative pain score at the breast; pre-operative overall pain score at rest; postoperative non-steroidal anti-inflammatory drug use; and pain catastrophising scale. Future research should validate this model and evaluate pre-emptive interventions to reduce persistent pain risk.

A Multicenter, Randomized, Open-Label Study to Compare the Efficacy and Safety of Tacrolimus and Corticosteroids in Combination With or Without Mycophenolate Mofetil in Liver Transplantation Recipients Infected With Hepatitis B Virus. Transplant Proc 2023; 55:387-395. [PMID: 36822884 DOI: 10.1016/j.transproceed.2023.01.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2022] [Revised: 12/12/2022] [Accepted: 01/05/2023] [Indexed: 02/24/2023]
Abstract
BACKGROUND Mycophenolate mofetil exhibits pharmacologic mechanisms different from calcineurin inhibitors. Therefore, the dose of calcineurin inhibitors can be reduced along with side effects for effective immunosuppression. We aimed to evaluate the efficacy and safety of tacrolimus and corticosteroid in combination with or without mycophenolate mofetil in living donor liver transplantation (LDLT) recipients infected with hepatitis B virus (HBV). METHODS A randomized, open-label, comparative, multicenter, phase IV study was conducted with 119 patients from January 2014 to September 2017. In the full analysis set population, 58 and 59 patients were included in the study group (triple-drug regimen: TacroBell + My-rept + corticosteroid) and the control group (dual-drug regimen: TacroBell + corticosteroid), respectively. In the per protocol set population, 49 and 42 patients were included in the study and control groups, respectively. RESULTS In the full analysis set population, the incidence of biopsy-proven acute cellular rejection (rejection activity index score ≥4) was 3.4% in the study group; however, this finding was not observed in the control group (P = .468). Hepatitis B virus recurrence was observed in one patient in the control group. No cases of biopsy-proven acute cellular rejection and HBV recurrence were observed in the per protocol set population. The incidences of serious adverse events were 25.9% and 18.0% in the study and control groups, respectively; however, the difference between the groups was not statistically significant (P = .376). CONCLUSION Although the study involved a small number of patients, the triple-drug regimen can be considered safe and effective for immunosuppression after living donor liver transplantation in patients infected with HBV.

Incidence of superficial left hepatic vein and its usability for graft hepatic vein venoplasty in pediatric liver transplantation. Pediatr Transplant 2023; 27:e14416. [PMID: 36261859 DOI: 10.1111/petr.14416] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Revised: 08/25/2022] [Accepted: 09/18/2022] [Indexed: 01/24/2023]
Abstract
BACKGROUNDS The anatomy of the left hepatic vein (LHV) is variable; thus, it should be considered for graft hepatic vein (GHV) venoplasty for left lateral section (LLS) and left liver grafts. This study assessed the incidence of superficial LHV (sLHV) branches according to LHV anatomy and its usability for GHV venoplasty in pediatric liver transplantation (LT). METHODS This study consisted of three parts: (1) anatomical classification of LHV variations and the incidence of sLHV branches; (2) morphometric simulative analysis of GHV reconstruction and (3) clinical application based on LHV anatomy. RESULTS The LHV anatomy of 248 potential LLS graft donors was classified into four types according to the number and location of GHV openings: one single opening (type 1; n = 186 [75.0%]), two large openings (type 2; n = 35 [14.1%]), one large and one small adjacent opening (type 3; n = 14 [5.6%]), and two large widely-separated openings (type 4; n = 13 [5.2%]). An sLHV branch was identified in 87 of 248 (35.1%) donor livers. Morphometric analysis of simulative GHV venoplasty with an sLHV branch increased GHV diameters by 30% in type 1 LLS grafts and 20% in type 2/3 LLS grafts. An analysis of 50 consecutive patients who underwent pediatric LT showed that the 2-year rates of GHV obstruction were 2.0% with LLS grafts and 0% with left liver grafts. CONCLUSIONS The GHV orifice can be enlarged through LHV anatomy-based unification venoplasty. Unification venoplasty with an sLHV branch provided sufficient enlargement of the GHV orifice.

Cytotoxicity of Human Hepatic Intrasinusoidal Gamma/Delta T Cells Depends on Phospho-antigen and NK Receptor Signaling. Anticancer Res 2023; 43:63-73.

Abstract
BACKGROUND/AIM We previously showed that human hepatic intrasinusoidal (HI) natural killer (NK) T cells selectively eliminate hepatocellular carcinoma (HCC) cell lines. In this study, we investigated the underlying mechanisms on how HI γδ T cells, expanded with zoledronate, exhibit a superior cytotoxic effect on HI NK-resistant Huh7 HCC cells. MATERIALS AND METHODS γδ T cells were obtained from living liver transplant donors or from peripheral blood mononuclear cells (PBMC) of healthy volunteers and were expanded in the presence of IL-2, IL-15, and zoledronate for 2 weeks. Cytotoxicity was measured using the lactate dehydrogenase (LDH) assay in vitro and by flow cytometry using carboxyfluorescein succinimidyl ester (CFSE) in vivo. RESULTS The cytotoxicity of expanded HI γδ T cells against Huh7 cells was associated with a higher pyrophosphate expression in Huh7 cells compared to SNU398 cells. In contrast, the cytotoxicity of HI γδ T cells against SNU398 cells depended on NKG2D. HI γδ T cells expressed less PD-1 than PB γδ T cells. The cytotoxicity of HI γδ T cells against Du145 and PC3 prostate cancer cells was also associated with pyrophosphate expression in these cells, as well as NKG2D and DNAM-1. CONCLUSION The expression levels of phospho-antigen in tumor cells determined the cytotoxicity of HI γδ T cells, although the NK activating receptors, death ligands, and immune checkpoint molecules also contribute to their cytotoxicity. γδ T cells are attractive candidates for cancer immune cell therapy.

Abstract
There is much controversy regarding enhanced recovery for recipients of liver transplants from deceased and living donors. The objectives of this Review were to summarise current knowledge on individual enhanced recovery elements on short-term outcomes, identify key components for comprehensive pathways, and create internationally accepted guidelines on enhanced recovery for liver-transplant recipients. The ERAS4OLT.org collaborative partnered by the International Liver Transplantation Society performed systematic literature reviews on the effect of 32 relevant enhanced perioperative recovery elements on short-term outcomes, and global specialists prepared expert statements on deceased and living donor liver transplantation. The Grading Recommendations, Assessment, Development and Evaluations approach was used for rating of quality of evidence and grading of recommendations. A virtual international consensus conference was held in January, 2022, in which results were presented, voted on by the audience, and discussed by an independent international jury of eight members, applying the Danish model of consensus. 273 liver transplantation specialists from 30 countries prepared expert statements on elements of enhanced recovery for liver transplantation based on the systematic literature reviews. The consensus conference yielded 80 final recommendations, covering aspects of enhanced recovery for preoperative assessment and optimisation, intraoperative surgical and anaesthetic conduct, and postoperative management for the recipients of liver transplants from both deceased and living donors, and for the living donor. The recommendations represent a comprehensive overview of the relevant elements and areas of enhanced recovery for liver transplantation. These internationally established guidelines could direct the development of enhanced recovery programmes worldwide, allowing adjustments according to local resources and practices.

Abstract
Backgrounds/Aims Although body surface area (BSA)-based standard liver volume (SLV) formulae have been used for living donor liver transplantation and hepatic resection, hemi-liver volume (HLV) is needed more frequently. HLV can be assessed using right or left portal vein diameter (RPVD or LPVD). The aim of this study was to validate the reliability of using portal vein diameter ratio (PVDR) for assessing HLV in living liver donors. Methods This study included 92 living liver donors (59 males and 33 females) who underwent surgery between January 2020 and December 2020. Computed tomography (CT) images were used for measurements. Results Mean age of donors was 35.5 ± 7.2 years. CT volumetry-measured total liver volume (TLV), right HLV, left HLV, and percentage of right HLV in TLV were 1,442.9 ± 314.2 mL, 931.5 ± 206.4 mL, 551.4 ± 126.5 mL, and 64.6% ± 3.6%, respectively. RPVD, LPVD, and main portal vein diameter were 12.2 ± 1.5 mm, 10.0 ± 1.3 mm, and 15.3 ± 1.7 mm, respectively (corresponding square values: 149.9 ± 36.9 mm2, 101.5 ± 25.2 mm2, and 237.2 ± 52.2 mm2, respectively). The sum of RPVD2 and LPVD2 was 251.1 ± 56.9 mm2. BSA-based SLV was 1,279.5 ± 188.7 mL (error rate: 9.1% ± 14.4%). SLV formula- and PVDR-based right HLV was 760.0 ± 130.7 mL (error rate: 16.2% ± 13.3%). Conclusions Combining BSA-based SLV and PVDR appears to be a simple method to predict right or left HLV in living donors or split liver transplantation.

Abstract
Complete pathological response (CPR) is achieved with various pretransplant locoregional treatments for hepatocellular carcinoma (HCC). This study aimed to investigate pretransplant expression of HCC tumor markers in liver transplantation (LT) recipients showing CPR. For the CPR group, 166 patients were selected from a single-institution LT database. Two control groups of 332 patients without HCC and 184 patients with partial pathological response (PPR) were also selected. The model for end-stage liver disease score in the CPR group was 11.5 ± 7.7. The number of transcatheter arterial chemoembolization sessions before LT was one in 68 patients (14.0%), two in 38 patients (22.9%), and three or more in 60 patients (36.1%). A solitary non-viable tumor was identified in 120 (86.4%) of the explant livers and the largest tumor size was 2.4 ± 1.3 cm. Living-donor and deceased-donor LTs were performed in 152 (91.6%) and 14 (8.4%) patients, respectively. The median levels of α-fetoprotein (AFP) and protein induced by Vitamin K absence or antagonist-II (PIVKA-II) measured within two weeks before LT were 4.2 ng/mL and 20 mAU/mL, respectively. These tumor marker levels were comparable to those in the no-HCC control group, but much lower than those in the PPR group (p < 0.001). Receiver operating characteristic curve analysis of AFP and PIVKA-II showed no definite cutoff values for CPR in the cohort of CPR and no-HCC patients, but significant cutoffs of 6.5 ng/mL for AFP and 29 mAU/mL for PIVKA-II were obtained in the cohort of CPR and PPR patients. The 1-, 3- and 5-year HCC recurrence and overall patient survival rates of the CPR group were 5.1% and 93.3%, 7.6% and 89.6%, and 7.6% and 89.6%, respectively. These tumor recurrence rates were much lower than those in the PPR group (p < 0.001). In conclusion, the present study results suggest that normalizing AFP and PIVKA-II after locoregional treatment is indicative of CPR. However, some CPR patients showed high expression of tumor markers; thus, pretransplant values of HCC tumor markers should be interpreted with caution.

Analysis of outcomes and renal recovery after adult living-donor liver transplantation among recipients with hepatorenal syndrome. Am J Transplant 2022; 22:2381-2391. [PMID: 35615988 DOI: 10.1111/ajt.17105] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 05/22/2022] [Accepted: 05/23/2022] [Indexed: 01/25/2023]
Abstract
When timely access to deceased-donor livers is not feasible, living-donor liver transplantation (LDLT) is an attractive option for patients with hepatorenal syndrome (HRS). This study's primary objective was to describe outcomes after LDLT among HRS recipients, and the secondary objective was to determine predictors of poor renal recovery after LDLT. This single-center, retrospective study included 2185 LDLT recipients divided into HRS (n = 126, 5.8%) and non-HRS (n = 2059, 94.2%) groups. The study outcomes were survival and post-LT renal recovery. The HRS group had a higher death rate than the non-HRS group (17.5% vs. 8.6%, p < 0.001). In the HRS group, post-LT renal recovery occurred in 69.0%, and the death rate was significantly lower in association with HRS recovery compared with non-recovery (5.7% vs. 43.6%, p < 0.001). Multivariable analysis indicated that post-LT sepsis (p < 0.001) and non-recovery of HRS (p < 0.001) were independent negative prognostic factors for survival. Diabetes mellitus (p = 0.01), pre-LT peak serum creatinine ≥3.2 mg/dl (p = 0.002), time interval from HRS diagnosis to LDLT ≥38 days (p = 0.01), and post-LT sepsis (p = 0.03) were important negative prognostic factors for renal recovery after LDLT. In conclusion, post-LT renal recovery was important for survival, and the interval from HRS to LDLT was significantly associated with post-LT renal recovery.

Optimizing pre-donation physiologic evaluation for enhanced recovery after living liver donation - Systematic review and multidisciplinary expert panel recommendations.

Abstract
BACKGROUND While preoperative physiologic evaluation of live liver donors is routinely performed to ensure donor safety and minimize complications, the optimal approach to this evaluation is unknown. OBJECTIVES We aim to identify predonation physiologic evaluation strategies to improve postoperative short-term outcomes, enhance donor's recovery, and reduce length of stay. We also aim to provide multidisciplinary expert panel recommendations. DATA SOURCES Ovid MEDLINE, Embase, Scopus, Google Scholar, and Cochrane Central. METHODS The systematic review followed PRISMA guidelines, and the recommendations were formulated using GRADE approach and experts' opinion. The search included retrospective or prospective studies, describing outcomes of physiologic evaluation predonation. The outcomes of interest were length of stay, postoperative complications (POC), recovery after donation, and mortality. PROSERO protocol ID CRD42021260662. RESULTS Of 1386 articles screened, only three retrospective cohort studies met eligibility criteria. Two studies demonstrated no impact of age (< 70 years) on POC. Increased body mass index's (BMI) association with POC was present in one study (23.8 vs 21.7 kg/m2 , OR 1.67 (1.14-2.48), P = .01) and absent in another (< 30 vs 30-35 kg/m2 , P = .61). One study demonstrated decreased risk for postdonation subclinical hepatic dysfunction in donors with higher normal platelet count (PLT). None of the studies noted donor death. Given the scarce data on predonation physiologic testing, the expert panel recommended a battery of tests to guide clinical practice and future investigations. CONCLUSION Advancing age (60-69 years) is not a contraindication for liver donation. There is insufficient evidence for a specific predonation BMI cut-off. Abbreviated predonation physiologic testing is recommended in all candidates. Comprehensive testing is recommended in high-risk candidates while considering the pretest probability in various populations (Quality of evidence; Low to Very Low | Grade of Recommendation; Strong).

Abstract
A microporous continuum traversed by a set of mutually perpendicular channels is considered to be a model for a hierarchically porous system of the mesoporous zeolite type. Transient profiles of molecular uptake as determined by kinetic Monte Carlo (kMC) simulation are found to be in excellent agreement with the result attained by the application of the two-region model (the Kärger model) of molecular diffusion. In particular, it is found that, in the two limiting cases referred to as fast exchange and slow exchange, there exist two simple analytical expressions for the rate of molecular uptake and hence for the quantification of transport enhancement in comparison with the purely microporous adsorbent. In the general case, transport enhancement is simply recognized by the reciprocal addition of the expressions in the two limiting cases.

Abstract
INTRODUCTION Lenvatinib is approved for the treatment of patients with metastatic or recurrent hepatocellular carcinoma (HCC); however, clinical outcomes of lenvatinib therapy in patients with post-liver transplantation (LT) HCC recurrence remain unclear. We investigated the efficacy and safety of lenvatinib in patients with post-LT HCC recurrence. METHODS This multinational, multicenter, retrospective study included 45 patients with recurrent HCC after LT who received lenvatinib at six institutions in three countries (Korea, Italy, and Hong Kong) from June 2017 to October 2021. RESULTS At the time of lenvatinib initiation, 95.6% (n = 43) of patients had Child-Pugh A status, and 35 (77.8%) and 10 (22.2%) participants were classified as having albumin-bilirubin (ALBI) grades 1 and 2, respectively. The objective response rate was 20.0%. With a median follow-up duration of 12.9 months (95% confidence interval [CI]: 11.2-14.7), the median progression-free survival and overall survival (OS) were 7.6 (95% CI: 5.3-9.8) months, and 14.5 (95% CI: 0.8-28.2) months, respectively. Patients with ALBI grade 1 showed significantly better OS (52.3 months, [95% CI: not assessable]) than patients with ALBI grade 2 (11.1 months [95% CI: 0.0-30.4 months], p = 0.003). The most common adverse events were hypertension (n = 25, 55.6%), fatigue (n = 17, 37.8%), and anorexia (n = 14, 31.1%). CONCLUSION Lenvatinib showed consistent efficacy and toxicity profiles in patients with post-LT HCC recurrence that were comparable to those reported from previous studies among non-LT HCC patients. The baseline ALBI grade correlated with better OS in post-LT lenvatinib-treated patients.
