Tumor spread along nerves, a phenomenon known as perineurial invasion, is common in various cancers including pancreatic ductal adenocarcinoma (PDAC). Neural invasion is associated with poor outcome, yet its mechanism remains unclear. Using the transgenic Pdx-1-Cre/KrasG12D /p53R172H (KPC) mouse model, we investigated the mechanism of neural invasion in PDAC. To detect tissue-specific factors that influence neural invasion by cancer cells, we characterized the perineurial microenvironment using a series of bone marrow transplantation (BMT) experiments in transgenic mice expressing single mutations in the Cx3cr1, GDNF and CCR2 genes...

"Turn-on" or "turn off" probes remain challenges in the establishmwnt of sensitive, easily operated and reliable methods for in situ monitoring bioactive substances. In the current study, electrospun fibrous strips are designed to provide straightforward observations of ratiometric color changes with naked eyes in the presence of serum heparin or urine trypsin. A tetraphenylethene (TPE) derivative is constructed and, along with phloxine B, is grafted on fibers, followed by protamine adsorption to induce static quenching of phloxine B and aggregation-induced emission of the TPE derivative...

Liver allocation in Eurotransplant is complex as allocation rules need to follow not only the guidelines of the European Commission but also the specific regulations of each of the 7 Eurotransplant countries with active liver transplant programs. Thirty-eight liver transplant centers served a population of about 135 million in 2015. Around 1600 deceased donor livers are transplanted annually. The number of deceased organ donors remains stable but donor age is increasing. Nevertheless, liver utilization rates are unchanged at around 80%...

The number of pancreas transplants performed in the United States stabilized over the last 3 years after nearly a decade of steady decline. Numbers of new additions to the list also stabilized during the same period. Notably, the persistent decline in pancreas after kidney transplants also seems to have abated, at least for now. The first full year of data after implementation of the new pancreas allocation system revealed no change in the distribution of organs between simultaneous pancreas-kidney (SPK) transplant and pancreas transplant alone...

PURPOSE: Solid organ transplants (SOT) continue to increase with recipients living longer than ever before. The lifelong immunosuppression in these patients also may place them at increased risk for postoperative complications. The efficacy of total hip arthroplasty (THA) in this patient population is undisputed but previous studies investigating the complication profiles in these patients often are underpowered to identify rare complications as well as make comparisons between individual organs...

Diabetes Mellitus (DM) is a systematic disease, which happens because of destruction of islets of Langerhans in the pancreas and systematic resistance to insulin. The lack of donor for pancreas transplantation and risk of transplant rejection is the main challenge in the treatment of this disease. Stem cells are proper and sufficient source for creating insulin-producing cells (IPC). In this study adipose tissue was provided from diabetic patients operated for liposuction and then adipose derived stem cells (ADSCs) were isolated, characterized and then treated by lentiviruses containing miR-375, after 7, 14 and 21 days of induction, islet-like clusters (ILC) specific genes including insulin and PDX1 were evaluated by Real Time RT-PCR...

Type 1 diabetes is an autoimmune disorder in which the immune system attacks and destroys insulin-producing islet cells of the pancreas. Although islet transplantation has proved to be successful for some patients with type 1 diabetes, its widespread use is limited by islet donor shortage and the requirement for lifelong immunosuppression. An encapsulation strategy that can prevent the rejection of xenogeneic islets or of stem cell-derived allogeneic islets can potentially eliminate both of these barriers. Although encapsulation technology has met several challenges, the convergence of expertise in materials, nanotechnology, stem cell biology and immunology is allowing us to get closer to the goal of encapsulated islet cell therapy for humans...

Pancreatic transplantation is currently the only effective cure for Type 1 diabetes mellitus. It allows long-term glycemic control without exogenous insulin and amelioration of secondary diabetic complications. In India, pancreas transplant has not yet established with only a single successful transplant reported so far in the literature. We report a 24-year-old Type 1 diabetic patient with renal failure who underwent a simultaneous pancreas kidney transplant. On postoperative day 15, he had leak from the graft duodenal stump for which a tube duodenostomy and proximal diversion enterostomy was done...

Islet transplantation (ITx) started in 2005 in IKEM as a potentially safer alternative to pancreas transplantation (PTx), which so far had represented the method of choice in type-1 diabetic patients with conservatively intractable hypoglycemia unawareness syndrome. The aim of the study was to compare these two methods with regard to severe hypoglycemia elimination and to frequency of complications.Up to November 2015 a total number of 48 patients underwent ITx. The results from 22 patients with hypoglycemia unawareness were statistically analyzed...

The lack of available organs remains one of the main limitations in the field of solid organ transplantation. Most transplant organizations work on improving donation rate through public information programs, and by exploring new organ sources, such as Donors after Cardio-circulatory Death (DCD).

BACKGROUND: Hemoglobin A1C (HbA1c) levels are often obtained in potential pancreas graft donors to assess the overall long-term functional glycemic control or the possibility of unrecognized diabetes. Although routinely measured, the impact of donor HbA1c levels on pancreas graft outcomes has not been reported. Here, we researched the relationship between donor HbA1c levels and postoperative pancreas graft survival. METHODS: Data from 266 pancreas transplant patients including 182 simultaneous kidney-pancreas and 84 pancreas alone transplants were reviewed for the study...

Enteric drainage has been the main trend in solitary pancreas transplantation. Compared with bladder drainage, it does not cause metabolic or urologic complications, but there is no way to perform immunologic monitoring, except by graft pancreas biopsy. Additionally, although portal drainage of the graft vein is considered physiological drainage, it has more of a risk for surgical complications. To overcome these disadvantages, we successfully performed inferior vena cava (IVC)-duodenal drainage in pancreas alone transplantation...

A 16-year-old white man was involved in a motor vehicle collision and suffered head, chest, and abdominal trauma. Despite initial resuscitative efforts, he progressed to brain death and was designated to be an organ donor by his family. He had no earlier medical or surgical history and no high-risk behaviors. Blood work revealed normal creatinine, liver function tests, lipase, and amylase. Viral serologies were negative except for cytomegalovirus IgG and Epstein-Barr virus nucleic acid. Imaging revealed a right kidney contusion, a manubrial fracture, and fractures of right first rib and bilateral scapulae...

BACKGROUND: There is still controversy about which preservation solution in pancreas transplantation could be the best. The aim of this study was to analyze our initial experience with Custodiol solution (CuS) compared with Viaspan solution (VS) and Celsior solution (CS) in pancreas transplantation. METHODS: A retrospective study included 94 consecutive pancreatic transplants, from 2007 until 2015. We compared 3 groups, depending on preservation solution: Viaspan (n = 41), Celsior (n = 40), or Custodiol (n = 13)...

BACKGROUND: The Pancreatic Donor Risk Index (PDRI) was developed in 2010 in the United States to predict graft survival after pancreas transplantation, based on donor characteristics and logistical and technical conditions. The aim of the study was to validate the utility of PDRI as a pancreas allograft survival predictor in simultaneous pancreas-kidney transplantation (SPK) transplants performed in our hospital between 2000 and 2015. METHODS: This retrospective analysis of 126 SPK transplants was performed by the same surgical team from the years 2000 to 2015...

INTRODUCTION: Simultaneous pancreas-kidney transplantation (SPKT) is a well treatment for patients with insulin-dependent diabetes and end-stage renal disease. Donor age is a barrier to the acceptance of organs. Age matching has been extensively studied in kidney transplantation; however, there are no studies in graft survival after SPKT. We aimed to study the combined influence of the ages of the donors and recipients in graft survival after SPKT. MATERIAL AND METHODS: Donors and recipients are classified as younger (age <40 years) or older (age ≥40 years)...
