BACKGROUND: The majority of kidney transplants are performed in recipients (RTR) over 50; simultaneously their life expectancy is improving. The increasing age and number of RTR is likely to be paralleled by an increase of prostate cancer (PCa) incidence. However, little is known on the optimal management of these patients who represent a therapeutic challenge due to medical and anatomical graft-related issues. METHODS: AMED, Medline and Embase were searched until November 17(th) , 2016 adhering to the PRISMA guidelines and the AMSTAR checklist to investigate oncological and functional outcomes of PCa treatment in RTR...

Søren Møller, Flemming Bendtsen
Patients with cirrhosis and portal hypertension often develop complications from a variety of organ systems leading to a multiple organ failure. The combination of liver failure and portal hypertension result in a hyperdynamic circulatory state partly owing to simultaneous splanchnic and peripheral arterial vasodilatation. Increases in circulatory vasodilators are believed to be due to portosystemic shunting and bacterial translocation leading to redistribution of the blood volume with central hypovolemia. Portal hypertension per se and increased splanchnic blood flow are mainly responsible for the development and perpetuation of the hyperdynamic circulation and the associated changes in cardiovascular function with development of cirrhotic cardiomyopathy, autonomic dysfunction, and renal dysfunction as part of a cardiorenal syndrome...

This case describes a patient being considered for combined liver-kidney transplantation for Caroli's disease with a failed renal transplant. A chronic septic focus could not be located with standard imaging techniques, such as ultrasonography and computed tomography. This case report highlights the observation that a retained non-functioning transplant can be the cause of fever of unknown origin and PET-CT can be useful in diagnosing these challenging cases.

Although overall downregulation of microRNAs (miRNAs) is a general feature of clear-cell renal cell carcinoma (ccRCC), several miRNAs are consistently upregulated, among which miR-122 was markedly increased in ccRCC tissues. This study aims to determine the functional importance and underlying mechanism of miR-122 in ccRCC metastasis. Here we demonstrate that the expression of miR-122 increased in ccRCC tissues, and higher miR-122 expression was found in ccRCC tissues with metastatic disease than in those without metastasis...

Normothermic ex vivo kidney perfusion (NEVKP) represents a novel approach for graft preservation and functional improvement in kidney transplantation. We investigated whether NEVKP also allows graft quality assessment prior to transplantation. Kidneys from 30kg pigs were recovered in a model of heart-beating donation (HBD) (group A), following 30min of warm ischemia (WI) (group B), or 60min WI (group C) (n=5/group). Following 8hrs of NEVKP, contralateral kidneys were resected, grafts autotransplanted, and pigs followed for 3 days...

ObjectivesAs high health care costs are increasing scrutinized, a movement toward reducing patient hospital admissions and lengths of stay has emerged, particularly for operations that may be performed safely in the outpatient setting. Our aim is to describe recent temporal trends in the proportion of dialysis access procedures performed on an inpatient vs. outpatient basis, and to determine the effects of these changes on perioperative morbidity and mortality. MethodsThe 2005-2008 ACS NSQIP database was queried for all primary arteriovenous fistula (AVF) procedures using CPT codes...

We have previously demonstrated that HDAC6 expression is increased in animal models of systemic lupus erythematosus (SLE) and that inhibition of HDAC6 decreased disease. In our current studies, we tested if an orally active selective HDAC6 inhibitor would decrease disease pathogenesis in a lupus mouse model with established early disease. Additionally, we sought to delineate the cellular and molecular mechanism(s) of action of a selective HDAC6 inhibitor in SLE. We treated 20-week-old (early-disease) NZB/W F1 female mice with two different doses of the selective HDAC6 inhibitor (ACY-738) for five weeks...

AIM: Accumulating evidence suggests that orexin signaling is involved in the regulation of blood pressure and cardiovascular function. However, the underlying mechanisms are not clear. Here we test the hypothesis that upregulated orexin A signaling in the paraventricular nucleus (PVN) increases sympathetic nerve activity (SNA) through stimulating expression of proinflammatory cytokines (PICs). METHODS: In vivo sympathetic nerve recordings were performed to test the impact of PVN orexin signaling on sympathetic outflow in Sprague-Dawley (SD) rats...

BACKGROUND: The demand for kidney retransplantation following graft failure is rising. Repeat transplantation is often associated with poorer outcomes due to both immunological and surgical challenges. The aim of this study was to compare surgical and functional outcomes of kidney retransplantation in recipients that had previously had at least 2 kidney transplants with a focus on those with antibody incompatibility. METHODS: We analysed 66 patients who underwent renal transplantation at a single centre between 2003 and 2011...

With the increasing prevalence of chronic kidney disease (CKD) worldwide, the number of pregnant women with various degrees of renal dysfunction is expected to increase. There is a bidirectional relation between CKD and pregnancy in which renal dysfunction negatively affects pregnancy outcomes, and the pregnancy can have a deleterious impact on various aspects of kidney disease. It has been shown that even mild renal dysfunction can increase considerably the risk of adverse maternal and fetal outcomes. Moreover, data suggest that a history of recovery from acute kidney injury is associated with adverse pregnancy outcomes...

BACKGROUND: A proportion of patients with an ICD in prevention of sudden cardiac death will only receive their first appropriate ICD therapy (AT) after device replacement. Clinical reassessment at the time of replacement could be helpful to guide the decision to replace or not in the future. METHODS: All patients with an ICD for primary or secondary prevention in ischemic (ICM) or non-ischemic cardiomyopathy were included in a single-center retrospective registry...

INTRODUCTION: Early allograft dysfunction (EAD) is a well-defined clinical syndrome that reflects overall graft function within the first week after transplant. The aim of this study was to further refine the definition for EAD. METHOD: In this study, 1124 patients were included for analysis. Logistic regression was performed to identify markers of liver injury associated with 6-month patient and graft failure. RESULTS: Recursive partitioning identified cut-points for ALT/AST >3000/6000IU/dL observed within 1(st) week, with bilirubin ≥10mg/dL and INR ≥1...

BACKGROUND: The primary objective of this study was to provide an assessment of NK cells in patients with ANCA-associated vasculitis (AAV). METHODS: Patients were classified based on the presence or absence of ANCAs and compared with healthy controls (HCs). By multiparameter flow cytometry, we evaluated the number and proportion of NK cells (CD3-CD56+) and the CD56(dim) , CD56(bright) , CD56(dim) CD57(bright) subsets; TLR2 and TLR9 expression; intracellular IFN-γ production upon stimulation with TLR2 and TLR9 ligands; degranulation activity; serum cytokines; immunohistochemical staining of available biopsies...

Renal function impairment in lung cancer patients with bone metastases was investigated, as this can limit the application of bisphosphonates representing the gold standard in the management of such cases. Clinicopathological data of 570 lung cancer patients were retrospectively analysed for changes in renal function parameters. Co-morbidities included hypertension (50%), COPD (33%) and diabetes mellitus (15%). Statistical analysis was performed with Fisher's exact tests and a Cox proportional hazards model...

Renal denervation (RDN) has been shown to have therapeutic values in patients with chronic kidney disease (CKD). This study aimed to investigate whether RDN could decrease susceptibility of the heart to ventricular fibrillation in a canine model of CKD. Twenty-one dogs were included in this study. CKD was produced by subtotal nephrectomy in sixteen dogs with RDN treatment (CKD + RDN group, N = 8) or sham RDN (CKD group, N = 8). Another 5 dogs underwent sham operation and sham RDN to serve as controls (CTR group)...

OBJECTIVE: Chemerin has been found to be highly expressed in the kidneys of rodents and has been suggested to affect metabolic syndrome (MetS)-related phenotypes which are in turn related to kidney damage. Only few clinical studies have addressed the relation between circulating chemerin and renal function in humans, and no population-based analyses have yet been performed. The potential influence of MetS-related phenotypes on the assumed association has been largely neglected. We aimed to investigate the association of serum chemerin with renal function in a general population with special regard to possible interactions between chemerin and metabolic phenotypes...

OBJECTIVE: Pharmacologic options for venous thromboembolism (VTE) prophylaxis are often limited in critically ill patients due to thrombocytopenia and multisystem organ dysfunction. Fondaparinux offers potential advantages in the critically ill; however, it is currently contraindicated in severe renal dysfunction (SRD). We evaluated antifactor Xa levels in critically ill patients with SRD who were receiving an extended interval dosing regimen of fondaparinux for VTE prophylaxis. METHODS: A prospective, single arm, interventional study was conducted at two academic hospitals of the Detroit Medical Center...
