BACKGROUND: We evaluated the effects of tailoring the operative approach on major surgical site complications and outcomes in lung transplant recipients. PATIENTS AND METHODS: Beginning in July 2013, bilateral lung transplants at a single institution were performed either through sternotomy or clamshell depending on proximity of hilar structures by computed tomography (CT), anticipated complexity, past surgical history, and surgeon experience. Patient demographics and outcomes were collected in the institution's Transplant Information Services (TIS)...

Type-1 Diabetes (T1D) is a devastating autoimmune disorder which results in the destruction of beta cells within the pancreas. A promising treatment strategy for T1D is the replacement of the lost beta cell mass through implantation of immune-isolated microencapsulated islets referred to as the bioartificial pancreas. The goal of this approach is to restore blood glucose regulation and prevent the long-term comorbidities of T1D without the need for immunosuppressants. A major requirement in the quest to achieve this goal is to address the oxygen needs of islet cells...

Background: This study aimed to analyze adult kidney transplant recipients (KTRs) for the risk of new-onset diabetes after transplantation (NODAT) associated with viral serologies and immunosuppression regimens [tacrolimus (Tac) + mycophenolate (MPA), cyclosporine (CSA) + MPA, sirolimus (SRL) + MPA, SRL + CSA or SRL +Tac]. Methods: Cox regression models were used to examine the risk of NODAT in the first posttransplant year associated with: (i) CSA + MPA, SRL + MPA, SRL + MPA or SRL + Tac versus reference, Tac + MPA; (ii) pretransplant viral serology [+ or -; hepatitis B core (HBc), hepatitis C (HCV), cytomegalovirus (CMV) or Epstein Barr Virus (EBV)]; and (iii) interactions between immunosuppression regimens and the viral serology found significant in the main analysis...

Post-transplant diabetes mellitus (PTDM) is common after most types of solid organ transplantation, though the actual incidence is as yet unknown because of the use of different diagnostic criteria. PTDM is the result of individual risk factors as well as risk factors associated with the transplant itself, particularly immunosuppressants. Previously called New Onset Diabetes, in many cases inadequate screening for diabetes before transplant cannot assure that the diabetes is new after transplant. The most recent international consensus guidelines suggest diagnosis should be delayed until the patient is taking maintenance doses of immunosuppressants even if they require treatment in the immediate hospitalization...

BACKGROUND Even though renal transplantation across blood groups is not uncommonly practiced nowadays, there is still hesitation regarding ABO-incompatible transplantation with very high baseline antibody titer. In this case report, the outcome of an ABO-incompatible kidney transplant recipient with a high baseline isoagglutinin titer is reported. CASE REPORT The patient was a non-diabetic, 33-year-old man with end-stage renal disease secondary to chronic glomerulonephritis. The only kidney donor available was his mother, who was blood-group incompatible...

BACKGROUND/AIM: Diabetic patients are at a higher risk of carcinogenesis and death from cancer, including colorectal cancer, than healthy individuals. The efficacy of cancer chemotherapy in the diabetic condition remains unclear. In this study, we investigated the efficacy of anticancer agents oxaliplatin and fluorouracil in streptozotocin (STZ)-treated hyperglycemic mice. MATERIALS AND METHODS: Starting 7 days after transplantation of colonic adenocarcinoma colon-26 cells, STZ-treated and control mice were intraperitoneally administered oxaliplatin, fluorouracil, and levofolinate (FOLFOX) every 2 weeks...

The long-term management of type-1 diabetes (T1D) is currently achieved through lifelong exogenous insulin injections. Although there is no cure for T1D, transplantation of pancreatic islets of Langerhans has the potential to restore normal endocrine function versus the morbidity of hypoglycemic unawareness that is commonly associated with sudden death among fragile diabetics. However, since endocrine islet tissues form a small proportion of the pancreas, sufficient islet numbers can be reached only by combining islets from multiple organ donors and the transplant plug contains significantly high levels of exocrine acinar tissue, thereby exacerbating immune responses...

BACKGROUND: Hyperoxaluria has been associated with nephrolithiasis as well as acute and chronic kidney disease. We present a case of end stage renal failure caused by excessive dietary oxalate intake in a dietary weight loss regimen. CASE PRESENTATION: A 51-year-old Caucasian male with the past medical history of type 2 diabetes mellitus, gout, hypertension and morbid obesity was referred to the primary care clinic after being found pale and easily fatigued. The patient had lost 36 kg over a 7-month period by implementing exercise and intense dietary measures that included 6 meals of spinach, kale, berries, and nuts...

Polycystic ovary syndrome is the classic example of loss of functional cyclicity and anomalous feedback. In this case, the excessive extra-glandular production and conversion of androgens to estrogens are the pathophysiological basis of the chronic anovulation. The literature describes an experimental model of the polymicrocystic ovary in obese diabetic mice with insulin resistance. The fact that these animals exhibit obesity, insulin resistance, and infertility demonstrates their skill as an experimental model for polycystic ovary...

Non-alcoholic fatty liver disease (NAFLD) occurs with higher prevalence in patients with inflammatory bowel disease (IBD) relative to the general population, and susceptibility is related to the metabolic syndrome, as well as higher prevalence of bowel resection and gut microbiotal factors. Liver complications, including NAFLD and primary sclerosing cholangitis (PSC) contribute to treatment and prognosis of patients with IBD. However, the potential interplay of NAFLD and PSC is not well understood. We retrospectively assessed severity of steatosis and steatohepatitis in liver specimens from 49 patients with IBD only, 44 with IBD and co-morbid PSC, and 30 with IBD and PSC after liver transplantation...

There is growing evidence that transplantation of cadaveric human islets is an effective therapy for type 1 diabetes. However, gauging the suitability of islet samples for clinical use remains a challenge. We hypothesized that islet quality is reflected in the expression of specific genes. Therefore, gene expression in 59 human islet preparations was analyzed and correlated with diabetes reversal after transplantation in diabetic mice. Analysis yielded 262 differentially expressed probesets, which together predict islet quality with 83% accuracy...

AIM: New-onset diabetes after kidney transplant (NODAT) adversely impacts kidney allograft and patient survival. Epigenetic alterations in adipose tissue like DNA methylation may play a contributory role. METHODS: Adipose tissue DNA of the patients with NODAT and their age, sex and BMI matched controls (nine each) were sequenced by reduced representation bisulfite sequencing. Differentially methylated CpGs (DMCs) and differentially methylated regions (DMRs) were studied...

Unlike other solid-organ transplants, whole pancreas transplantation in children is relatively rare, and it occurs more frequently in the context of multivisceral or composite organ transplantation. Because children only infrequently suffer severe sequelae of type 1 diabetes mellitus, pancreas transplantation is rarely indicated in the pediatric population. More commonly, pediatric pancreas transplant occurs in the setting of incapacitating acute recurrent or chronic pancreatitis, specifically islet autotransplantation after total pancreatectomy...

Islet transplantation has the potential of reestablishing naturally-regulated insulin production in Type 1 diabetic patients. Nevertheless, this procedure is limited due to the low islet survival after transplantation and the lifelong immunosuppression to avoid rejection. Islet embedding within a biocompatible matrix provides mechanical protection and a physical barrier against the immune system thus, increasing islet survival. Alginate is the preferred biomaterial used for embedding insulin-producing cells because of its biocompatibility, low toxicity and ease of gelation...

BACKGROUND: Multipotent mesenchymal stromal cells (MSC) enhance viability and function of islets of Langerhans. We aimed to examine the interactions between human MSC and human islets of Langerhans that influence the function of islets. METHODS: Human MSC and human islets (or pseudoislets, obtained after digestion and reaggregation of islet cells) were cocultured with or without cellular contact and glucose-stimulated insulin secretion assays were performed to assess cell function...
