Background: Cardiac disease is highly prevalent in hemodialysis (HD) patients. Decreased tissue perfusion, including cardiac, due to high ultrafiltration volumes (UFVs) is considered to be one of the drivers of cardiac dysfunction. While central venous oxygen saturation (ScvO 2 ) is frequently used as an indicator of cardiac output in non-uremic populations, the relationship of ScvO 2 and UFV in HD patients remains unclear. Our aim was to determine how intradialytic ScvO 2 changes associate with UFV...

BACKGROUND: Non-HLA-antibodies against human endothelial progenitor cells (EPC) in pre-transplant recipient serum can have a deleterious influence on the graft. EPC enriched from peripheral blood have been commonly used for EPC crossmatching. In the present study, we describe crossmatches using EPC enriched from fresh or frozen-thawed spleen cell preparations, thereby widening the sample source for deceased-donor crossmatching and retrospective studies. METHODS: EPC crossmatches were performed retrospectively using spleen cells and the flow cytometric XM-ONE crossmatch test kit...

BACKGROUND AND OBJECTIVES: RRT and doubling of serum creatinine are considered the objective hard end points in nephrology intervention trials. Because both are assumed to reflect changes in the filtration capacity of the kidney, drug effects, if present, are attributed to kidney protection. However, decisions to start RRT are not only on the basis of filtration capacity of the kidney, but also on other factors. We therefore compared the time to RRT with the time to a fixed eGFR threshold and assessed the effect of the renoprotective drug irbesartan on both components...

BACKGROUND: Abdominal aortic aneurysms pose a substantial clinical burden, and a significant proportion are not anatomically suitable for open repair or standard endovascular aneurysm repair (EVAR), instead requiring fenestrated EVAR (fEVAR). We sought to compare clinical outcomes and trends over time in patients undergoing fEVAR in Australia. METHODS: We conducted a retrospective analysis of all patients undergoing fEVAR at a tertiary referral centre between 2010 and 2015, including outcomes and complications, both as inpatients and after discharge...

Patients with hypoplastic left heart syndrome (HLHS) can have associated genetic abnormalities. This study evaluated the incidence of genetic abnormalities among infants with HLHS and the short-term outcomes of this population during the first hospitalization. This is a retrospective analysis of the multi-center Pediatric Heath Information System database of infants with HLHS who underwent Stage I Norwood, Hybrid, or heart transplant during their first hospitalization from 2004 through 2013. We compared clinical data between infants with and without genetic abnormality, among the three most common chromosomal abnormalities, and between survivors and non-survivors...

Autologous hematopoietic cell transplantation (AHCT) in multiple myeloma (MM) patients with renal insufficiency (RI) is controversial. Patients who underwent AHCT for MM between 2008 and 2013 were identified (N=1492) and grouped as normal/mild (⩾60 mL/min), N=1240, moderate (30-59), N=185 and severe RI (<30), N=67 based on Modification of Diet in Renal Disease. Multivariate analyses of non-relapse mortality (NRM), relapse, PFS and overall survival (OS) were performed. Of the 67 patients with severe RI, 35 were on dialysis prior to AHCT...

Hematologic response criteria in light chain (AL) amyloidosis require the difference in involved and uninvolved free light chains (dFLC) to be at least 5 mg/dl. We describe the clinical presentation and outcomes of newly diagnosed amyloidosis patients with dFLC<5 mg/dl (non-evaluable dFLC; 14%, n=165) compared to patients with dFLC ⩾5 mg/dl (evaluable dFLC; 86%, n=975). Patients with non-evaluable dFLC had less cardiac involvement (40 vs 80%, P<0.001), less liver involvement (11 vs 17%, P=0.04) and a trend towards less gastrointestinal involvement (18 vs 25%, P=0...

BACKGROUND: Volume overload results in higher mortality rates in patients on continuous ambulatory peritoneal dialysis (CAPD). The ratio of bioimpedance (RBI) might be a helpful parameter in adjusting dry body weight in CAPD patients. This study examined whether it is possible to distinguish between non-hypervolemic status and hypervolemic status in CAPD patients by using only RBI. METHODS: RBI was calculated as follows: RBI = impedance at 50 kHz/impedance at 500 kHz...

The epidemiology and outcomes of tumor lysis syndrome (TLS) are understudied. We used the National Inpatient Sample (NIS), a nationally representative weighted sample of all U.S. hospital discharges, to study outcomes and predictors of mortality in hospitalized patients with TLS. The NIS was queried for patients with a discharge diagnosis of TLS (ICD-9 code 277.88) from 2010-2013. Baseline characteristics and outcomes were analyzed. A multivariable logistic regression analysis was performed to identify predictors of mortality...

BACKGROUND: Chronic fluid overload is common in patients with chronic kidney disease (CKD) and can with time lead to diastolic dysfunction and heart failure. We investigated whether markers of fluid status, such as NT-proBNP and bioimpedance spectroscopy (BIS), can predict echocardiographic findings of diastolic dysfunction in non-dialysis CKD5 patients. METHODS: BIS, echocardiography, and measurement of serum NT-proBNP were performed in patients with non-dialysis CKD stage 5 at a single study visit...

BACKGROUND: The literature notes high prevalence of cognitive function (CF) impairment among hemodialysis patients. Renal transplantation by reversing metabolic factors should improve cognitive function; however, results in post-transplant patients are inconsistent. Lack of longitudinal studies, variable and small patient population, variable renal function and post-transplantation period and use of non-specific tests make results difficult to interpret. We looked at CF in stable hemodialysis patients just prior to live renal transplantation and approximately 3 months subsequently using well-validated electrophysiological study of P300 cognitive potential obtained by auditory oddball paradigm using multiple scalp electrodes...
