REVIEW
Hiroshi Date
Living-donor lobar lung transplantation (LDLLT) was developed to deal with the severe shortage of brain dead door for patients who would not survive the long waiting period. In standard LDLLT, right and left lower lobes removed from two healthy donors are implanted into a recipient after right and left pneumonectomies using cardiopulmonary bypass (CPB). The number of LDLLT has decreased in the USA due to the recent change in allocation system for cadaveric donor lungs. For the past several years, most of the reports on LDLLT have been from Japan, where the average waiting time for a cadaveric lung is exceeding 800 days...

BACKGROUND: Use of Enhanced recovery after surgery (ERAS) pathways to accelerate functional recovery and reduce length of stay (LOS) has rarely been investigated in kidney transplantation (KTX). MATERIALS AND METHODS: Consecutive adult isolated KTXs between 7/2015-7/2016 (ERAS, n=139) were compared with a historical cohort between 1/2014-7/2015 (HISTORIC, n=95). RESULTS: ERAS recipients were significantly more likely to receive kidneys that were non-local (56...

BACKGROUND: Pancreatic islet transplantation is currently proven as a promising treatment for type 1 diabetes patients with labile glycemic control and severe hypoglycemia unawareness. Upon islet transplantation, revascularization is essential for proper functioning of the transplanted islets. As IL-6 is important for endothelial cell survival and systemic inflammation related to xenograft, the effect of IL-6 receptor antagonist, tocilizumab, on revascularization of the transplanted islets was examined in pig to non-human primate islet xenotransplantation model...

Late occurrence of antibody-mediated rejection (AMR), defined as occurring 6 months after transplantation, is associated with poor renal allograft survival, compared to early acute AMR and acute cellular rejection. The proteasome inhibitor bortezomib has multiple immunomodulatory effects on plasma cells, the source of donor-specific HLA antibodies which mediate AMR. MATERIALS AND METHODS: Consecutive patients who presented with biopsy-proven AMR and donor-specific anti-HLA antibodies (DSA) at a single institution between July 2011 and February 2015 were included...

OBJECTIVES: Prognostic implications of early protocol biopsies have been studied; however, the value of late protocol biopsy in predicting graft outcome has not been well defined. Here, we compared the effects of early and late protocol biopsy histologic findings in stable kidney allografts and aimed to understand the significance of "borderline" rejection on allograft function. MATERIALS AND METHODS: We studied 261 biopsies from 159 renal transplant recipients who were on a steroid-free, calcineurin inhibitor and mycophenolate mofetil regimen and who received transplants between 2004 and 2012 with mean follow-up of 5 years...

Intestinal failure characterized by inadequate maintenance of nutrition via normal intestinal function comprises a group of disorders with many different causes. If parenteral nutrition dependency develops, which is associated with higher mortality and complications, it is considered for intestine transplantation. However, the graft failure rate is not low, and acute cellular rejection is one of the most important reasons for graft failure. As a result, early identification of rejection and timely modification of anti-rejection medications have been considered to be associated with better graft and patient survival rates...

BACKGROUND: Systemic inflammation affects kidney function in a wide range of diseases. Even in kidney transplant recipients, higher levels of C-reactive protein (CRP) are invariably associated with both worse short- and long-term graft outcomes. However, little is known about systemic inflammation in kidney donors and, notably, brain death causes a strong systemic inflammatory response. OBJECTIVE: To analyze the role of systemic inflammation of brain-dead donors on short-term kidney graft outcomes (ie, delayed graft function [DGF], defined as the need of dialysis during the first week after transplantation)...

PURPOSE: The effectiveness of ACL functional knee braces to reduce meniscal and ACL strain after ACL injury or reconstruction is not well understood. A new dynamic knee tensioning brace system has been designed to apply an active stabilizing force to the knee. The ability of this system to reduce tissue strains is unknown. The purpose of this study was to test the ability of the dynamically tensioned brace to reduce strain in both the ACL and meniscus during rehabilitation activities...

Activity dependent plasticity is a key mechanism for the central nervous system (CNS) to adapt to its environment. Whether neuronal activity also influences axonal regeneration in the injured CNS, and whether electrical stimulation (ES) can activate regenerative programs in the injured CNS remains incompletely understood. Using KCl-induced depolarization, in vivo ES followed by ex-vivo neurite growth assays and ES after spinal cord lesions and cell grafting, we aimed to identify parameters important for ES-enhanced neurite growth and axonal regeneration...

BACKGROUND: The incidence and impact of adverse drug events (ADEs) leading to hospitalization and as a predominant risk factor for late graft loss has not been studied in transplantation. METHODS: This was a longitudinal cohort study of adult kidney recipients transplanted between 2005 and 2010 and followed through 2013. There were 3 cohorts: no readmissions, readmissions not due to an adverse drug event, and adverse drug events contributing to readmissions. The rationale of the adverse drug events contribution to the readmission was categorized in terms of probability, preventability, and severity...

Prepectoral breast reconstruction has emerged as an excellent technique for postmastectomy reconstruction, as it allows for full preservation of a patient's pectoralis major muscle and chest wall function. This reduces pain, eliminates animation deformity, and results in high patient satisfaction. Safely performed prepectoral breast reconstruction requires a careful patient selection process before committing to the procedure, taking into account comorbidities, radiation status, and oncologic criteria such as tumor location and breast cancer stage...

Kidney paired donation (KPD) is an important tool to facilitate living donor kidney transplantation (LDKT). Concerns remain over prolonged cold ischemia times (CIT) associated with shipping kidneys long distances through KPD. We examined the association between CIT and delayed graft function (DGF), allograft survival, and patient survival for 1,267 shipped and 205 non-shipped/internal KPD LDKTs facilitated by the National Kidney Registry in the United States from 2008-2015, compared to 4,800 unrelated, non-shipped, non-KPD LDKTs...

Little is known about the impact of CYP3A5 polymorphisms on transplantation outcomes among African-American (AA) kidney transplant recipients. To assess this issue, clinical outcomes were compared between AA CYP3A5*1 expressers versus non-expressers. This retrospective cohort study analyzed AA kidney transplant recipients. Biopsy-proven acute rejection (BPAR), delayed graft function (DGF), glomerular filtration rate (GFR), infections and tacrolimus dosing requirements were examined in 106 immunologically high-risk AA kidney transplant patients over a 2 year follow-up period...

BACKGROUND: Death with graft function (DWGF) is an important cause of long-term loss of grafts and patients. In this study, we investigated clinical characteristics and causes of DWGF in kidney transplant recipients. METHODS: We recruited kidney allograft recipients who underwent surgery during 1973-2016 at Seoul National University Hospital in Korea (n = 2137). We divided recipients into four groups: alive with graft function (AWGF), alive with graft loss (AWGL), DWGF, and death with graft loss (DWGL)...

BACKGROUND: Recently, urinary tissue inhibitor of metalloproteinase-2 (TIMP-2) and insulin-like growth factor-7 (IGFBP-7), markers for G1 cell cycle arrest, have been identified and validated in predicting the development of acute kidney injury in critically ill patients. It is unknown, however, whether these two biomarkers could predict the development of delayed graft function (DGF) after kidney transplantation (KT). METHODS: This is a single-center, prospective, observational study...

BACKGROUND Delayed graft function (DGF) is a common complication that impairs allograft function after kidney transplantation. However, the mechanism of DGF remains unclear. Nuclear magnetic resonance (NMR)-based analysis has been widely used in recent times to assess changes in metabolite levels. MATERIAL AND METHODS Samples of perfusate from allografts donated after circulatory death were collected prior to transplantation, during static cold storage. ¹H-NMR-based metabolomics combined with the statistical methods, orthogonal partial least-squares discriminant analysis (OPLS-DA), and principle-component analysis (PCA), were employed to test different levels of metabolites between the allografts that exhibited DGF and those that exhibited immediate graft function (IGF)...

BACKGROUND: Using kidneys from deceased donors is an available strategy to meet the growing need of grafts. However, higher incidences of delayed graft function (DGF) and acute rejection exert adverse effects on graft outcomes. Since ischemia-reperfusion injury (IRI) and ongoing process of immune response to grafts are the major causes of DGF and acute rejection, the optimal induction intervention should possess capacities of both repairing renal structure injury and suppressing immune response simultaneously...

Anatomically contoured healing abutments have been shown to contain and protect slow-resorbing substitution grafts, resulting in bone and soft-tissue volume augmentation. Even in healed sites customized healing abutments have demonstrated favorable outcomes compared to standard healing abutments. Through two separate cases, this article describes a technique that enables simple chairside fabrication of precisely contoured customized healing abutments and exact 3-dimensional intraoral positioning. With this technique, the soft tissues upon maturation closely resemble the natural root contour, which allows for the generation of esthetic and functional implant-supported restorations...

Beyond the first posttransplant year, 3% of kidney transplants fail annually. In a prospective, multicenter cohort study, we tested the relative impact of early versus late events on risk of long-term death-censored graft failure (DCGF). In grafts surviving at least 90 days, early events (acute rejection [AR] and delayed graft function [DGF] before day 90) were recorded; serum creatinine (Cr) at day 90 was defined as baseline. Thereafter, a 25% rise in serum Cr or new onset proteinuria triggered graft biopsy (index biopsy, IBx), allowing comparison of risk of DCGF associated with early events (AR, DGF, baseline serum Cr >2...
