Major concerns about donor safety cause controversy and limit the use of living donor liver transplantation to overcome organ shortages. The Korean Organ Transplantation Registry established a nationwide organ transplantation registration system in 2014. We reviewed the prospectively collected data of all 832 live liver donors who underwent procedures between April 2014 and December 2015. We allocated the donors to a left lobe group (n=59) and a right lobe group (n=773) and analyzed the relations between graft types and remaining liver volumes and complications (graded using the Clavien five-tier grading system)...

Echocardiography is commonly performed as a screening test to evaluate perioperative risks before kidney transplantation. However, only limited data are available on echocardiographic parameters of left ventricular diastolic dysfunction (LVDD) and left atrial enlargement (LAE) on acute coronary syndrome and mortality in kidney transplant recipients. We reviewed 2779 adult recipients who underwent pretransplant echocardiography from 1997 to 2012. We divided the patients into two and four groups by two categories: LVDD grades 0-1 vs...

BACKGROUND: Adequate portal vein (PV) flow in liver transplantation is essential for a good outcome, and it may be compromised in patients with portal vein thrombosis (PVT). This study evaluated the impact of intraoperatively measured PV flow after PV thrombendvenectomy on outcomes after deceased donor liver transplantation. STUDY DESIGN: The study included 77 patients over a 16-year period who underwent PV thrombendvenectomy with complete flow data. Patients were classified into two groups: high PV flow (>1300 mL/min, N = 55) and low PV flow (≤1300 mL/min, N = 22)...

Adult stem cells have been studied as a promising therapeutic modality for the functional restoration of the damaged heart. In the present study, a strategy for enhancing the angiogenic efficacy of human mesenchymal stem cells (hMSCs) using micro-RNA was examined. We investigated whether micro-RNA-146a (miR-146a) influences the secretion of vascular endothelial growth factor (VEGF) and angiogenesis of MSCs. Our data indicated that miR-146a-transfected hMSCs (hMSCmiR-146a) decreased the expression of neurofibromin 2, an inhibitor of p21-activated kinase-1 (PAK1)...

Allogeneic hematopoietic cell transplantation (HCT) is recommended for T-cell acute lymphoblastic leukemia (T-ALL) in second or later complete remission (CR) and in high risk patients in first CR. Given its relative rarity, data on outcomes of HCT for T-ALL are limited. We conducted a multi-center retrospective cohort study using data from 208 adult patients transplanted from 2000-2014 to describe outcomes of allogeneic HCT for T-ALL in the contemporary era. Median age at HCT was 37 years and the majority of patients were transplanted in CR, using total body irradiation (TBI) based myeloablative conditioning regimens...

BACKGROUND: Effective treatment options for patients with chronic myeloid leukemia (CML) or Philadelphia-positive (Ph+) acute lymphoblastic leukemia (ALL) who have the threonine to isoleucine mutation at codon 315 (T315I) are few. The objective of this study was to compare overall survival (OS) between patients with CML and those with Ph+ ALL who received treatment with ponatinib versus allogeneic stem cell transplantation (allo-SCT). METHODS: A post hoc, retrospective, indirect comparison of OS among patients who received single-agent ponatinib in the Ponatinib Ph+ ALL and CML Evaluation (PACE) trial with those who underwent allo-SCT as reported to the European Bone Marrow Transplant registry, stratified by CML disease phase and Ph+ ALL, was conducted...

A 12-year-old castrated Toy Poodle was referred to Kangwon National University Animal Hospital with an oligotrophic nonunion fracture in the left distal 1/3 of the radius and an intact ulna. After fixation using a locking plate and screws, adipose-derived mesenchymal stem cell sheets expressing bone morphogenetic protein 7 (BMP-7) were transplanted to the fracture site to enhance the healing activity. The fracture healed at 9 weeks after surgery. In the present case, the mesenchymal stem cell sheets expressing BMP-7 promoted bone regeneration and healing in a nonunion fracture...

Although acyclovir prophylaxis against varicella zoster virus (VZV) infection for ≥1 year is recommended after allogeneic hematopoietic cell transplantation (HCT), the emergence of acyclovir-resistant viruses and adverse drug effects cannot be ignored. We investigated the cumulative incidence of VZV infection after allogeneic HCT in children receiving a shorter duration of acyclovir prophylaxis than recommended and evaluated the appropriateness of the short duration of acyclovir prophylaxis.Medical records of 217 children who received allogeneic HCT were retrospectively reviewed until a median of 25 months (range = 1-59 months) after HCT...

Sirolimus (SIR)/tacrolimus (TAC) is an alternative to methotrexate (MTX)/TAC. However, rational selection among these GvHD prophylaxis approaches to optimize survival of individual patients is not possible based on current evidence. We compared SIR/TAC (n=293) to MTX/TAC (n=414). The primary objective was to identify unique predictors of overall survival (OS). Secondary objective was to compare acute and chronic GvHD, relapse, non-relapse mortality, thrombotic microangiopathy (TMA), hepatic veno-occlusive disease (VOD/SOS), and acute kidney injury...

Type 1 diabetes (T1D) can be managed by transplanting either the whole pancreas or isolated pancreatic islets. However, cadaveric pancreas is scarcely available for clinical use, limiting this approach. As such, there is a great need to identify alternative sources of clinically usable pancreatic tissues. Here, we used induced pluripotent stem (iPS) cells derived from patients with T1D to generate glucose-responsive, insulin-producing cells (IPCs) via 3D culture. Initially, T1D iPS cells were resistant to differentiation, but transient demethylation treatment significantly enhanced IPC yield...

Extracellular matrix (ECM) is crucial to many aspects of vascular morphogenesis and maintenance of vasculature function. Currently the recapitulation of angiogenic ECM microenvironment is still challenging, due mainly to its diverse components and complex organization. Here we investigate the angiogenic potential of human lung fibroblast-derived matrix (hFDM) in creating a three-dimensional (3D) vascular construct. hFDM was obtained via decellularization of in vitro cultured human lung fibroblasts and analyzed via immunofluorescence staining and ELISA, which detect multiple ECM macromolecules and angiogenic growth factors (GFs)...
