In tissue engineering, an ideal scaffold attracts and supports cells thus providing them with the necessary mechanical support and architecture as they reconstruct new tissue in vitro and in vivo. This manuscript details a novel matrix derived from decellularized Wharton's jelly (WJ) obtained from human umbilical cord for use as a scaffold for tissue engineering application. This decellularized Wharton's jelly matrix (DWJM) contained 0.66 ± 0.12 μg/mg sulfated glycosaminoglycans (GAGs), and was abundant in hyaluronic acid, and completely devoid of cells...

Recently, I attended a meeting of the Oncofertility Consortium and had one of those "a-ha" moments that change one's perspective in a very real way. A surgeon from Sweden was talking about uterus transplantations, and she described how these came about. She told a story about one of her colleagues, who was talking to a young woman who had cervical cancer and had a hysterectomy. The patient asked the physician if they could give her a "new" uterus so that one day she could have a biological child. The physician told her that was not possible and the patient responded, "Why not?" That prompted the physician to start a new field of research, uterine transplantation, that has had some early successes, as well as many failures...

BACKGROUND: Vascularized composite allografts, particularly hand and forearm, have limited ischemic tolerance after procurement. In bilateral hand transplantations, this demands a 2 team approach and expedited transfer of the allograft, limiting the recovery to a small geographic area. Ex situ perfusion may be an alternative allograft preservation method to extend allograft survival time. This is a short report of 5 human limbs maintained for 24 hours with ex situ perfusion. METHODS: Upper limbs were procured from brain-dead organ donors...

BACKGROUND: Systemic inflammation associated with brain death (BD) decreases islet yield and quality, negatively affecting outcomes of human islet transplantation. A recent study from our group showed an increased expression of uncoupling protein-2 (UCP2) in pancreas from rats with BD as compared with controls. UCP2 is located in the mitochondrial inner membrane and regulates production of reactive oxygen species and glucose-stimulated insulin secretion. It has been suggested that UCP2 also plays a role in β cell apoptosis, but these findings remain controversial...

BACKGROUND: Not much data are available on the natural history of bilateral renal agenesis, as the medical community does not typically offer aggressive obstetric or neonatal care asbilateral renal agenesis has been accepted as a lethal condition. AIM: To provide an evidence-based, ethically justified approach to counseling pregnant women about the obstetric management of bilateral renal agenesis. STUDY DESIGN: A systematic literature search was performed using multiple databases...

Purpose To evaluate the efficacy and safety of a clofarabine-based combination (CLARA) versus conventional high-dose cytarabine (HDAC) as postremission chemotherapy in younger patients with acute myeloid leukemia (AML). Patients and Methods Patients age 18 to 59 years old with intermediate- or unfavorable-risk AML in first remission and no identified donor for allogeneic stem-cell transplantation (SCT) were eligible. Two hundred twenty-one patients were randomly assigned to receive three CLARA or three HDAC consolidation cycles...

BACKGROUND: The association of HLA mismatching with kidney allograft survival has been well established. We examined whether amino acid mismatches at the antigen recognition site of HLA molecules represent independent and incremental risk factors for kidney graft failure (GF) beyond those mismatches assessed at the antigenic (2-digit) specificity. METHODS: Data on 240,024 kidney transplants performed between 1987 and 2009 were obtained from the Scientific Registry of Transplant Recipients...

Following single-lung transplantation (SLT), there is significant redistribution of flow preferentially to the transplanted lung. Altered lung perfusion leads to unusual results when performing pulmonary scintigraphy, which could result in interpretation errors. We present pulmonary scintigraphy images from a 67-year-old female patient with history of chronic obstructive pulmonary disease that were obtained before SLT, 10 days after SLT, and 3 months after SLT.

PURPOSE OF REVIEW: Despite modern immunosuppression, renal allograft rejection remains a major contributor to graft loss. Novel biomarkers may help improve posttransplant outcomes through the early detection and treatment of rejection. Our objective is to provide an overview of proteomics, review recent discovery-based rejection studies, and explore innovative approaches in biomarker development. RECENT FINDINGS: Urine MMP7 was identified as a biomarker of subclinical and clinical rejection using two-dimensional liquid chromatography tandem-mass spectrometry (LC-MS/MS) and improved the overall diagnostic discrimination of urine CXCL10 : Cr alone for renal allograft inflammation...

We conducted a case-control study of 18 US transplant recipients with Rhodococcus infection and 36 matched controls. The predominant types of infection were pneumonia and bacteremia. Diabetes mellitus and recent opportunistic infection were independently associated with disease. Outcomes were generally favorable except for 1 relapse and 1 death.

Extracorporeal photopheresis (ECP) has been used for over 35 years in the treatment of erythrodermic cutaneous T-cell lymphoma (CTCL) and over 20 years for chronic and acute graft-versus-host disease (GvHD) and solid organ transplant rejection. ECP for CTCL and GvHD is available at specialised centres across the UK. The lack of prospective randomised trials in ECP led to the development of UK Consensus Statements for patient selection, treatment schedules, monitoring protocols and patient assessment criteria for ECP...

Cell sheet therapy has emerged as a potential therapeutic option for reparation and reconstruction of damaged tissues and organs. However, an effective means to assess the fate and distribution of transplanted cell sheets in a serial and noninvasive manner is still lacking. To investigate the feasibility of tracking Adipose derived stem cells (ADSCs) sheet in vivo using ultrasmall super-paramagnetic Fe3O4 nanoparticles (USPIO), canine ADSCs were cultured and incubated with USPIO and 0.75 μg/ml Poly-L-Lysine (PLL) for 12 h...

INTRODUCTION    Antibodies against donor`s human leukocyte antigens (HLA) play a significant role in the pathogenesis of antibody mediated rejection, although their role during the late post-transplant period is unknown. A non-HLA polymorphic antigenic system like major histocompatibility class I chain-related antigen A (MICA) might be another target for antibody responses involved in rejection. OBJECTIVES    We conducted a 7-year prospective study to determine the effect of positivity for anti-HLA and anti-MICA antibodies on kidney graft survival...

In April 2014, a kidney transplant recipient in the United States experienced headache, diplopia, and confusion, followed by neurologic decline and death. An investigation to evaluate the possibility of donor-derived infection determined that 3 patients had received 4 organs (kidney, liver, heart/kidney) from the same donor. The liver recipient experienced tremor and gait instability; the heart/kidney and contralateral kidney recipients were hospitalized with encephalitis. None experienced gastrointestinal symptoms...

BACKGROUND: Calcific uraemic arteriolopathy (calciphylaxis) is an unusual and potentially fatal condition characterised by small-vessel calcification and ischaemic skin necrosis. It mainly affects patients with end-stage renal disease (ESRD) on haemodialysis, but may rarely occur in the absence of ESRD in conditions such as primary hyperparathyroidism, malignancy, alcoholic liver disease and connective tissue disease. METHODS: We reviewed the records of all patients diagnosed with calciphylaxis while on renal replacement therapy at Tygerberg Hospital, Cape Town, South Africa, between 1990 and 2014, to describe its presentation, course and final outcome...
