Little is known about potential differences in binding characteristics of protein-bound uremic toxins (PBUTs) in patients with chronic kidney disease (CKD) versus healthy controls. The question arises whether eventual differences are attributed to (i) the elevated levels of competing uremic toxins, and/or (ii) post-translational modifications of albumin. We evaluated the binding characteristics of hippuric acid (HA), indole-3-acetic acid (IAA), indoxyl sulfate (IS), and p-cresylsulfate (pCS) by deriving a binding curve in three distinct conditions: (i) serum from healthy controls (healthy serum), (ii) blank serum from hemodialysis patients (blank HD serum; i...

Chronic Kidney Disease (CKD) is a major burden on patients and the health care system. Treatment of CKD requires dedicated involvement from both caretakers and patients. Self-efficacy, also known as perceived competence, contributes to successful maintenance of patient's CKD self-management behaviors such as medication adherence and dietary regulations. Despite a clear association between self-efficacy and improved CKD outcomes, there remains a lack of validated self-report measures of CKD self-efficacy. To address this gap, the Perceived Kidney/Dialysis Self-Management Scale (PKDSMS) was adapted from the previously validated Perceived Medical Condition Self-Management Scale...

Recent literature suggests an increase in the incidence of acute kidney injury (AKI). We evaluated population-based trends of AKI over the course of nine years, using a validated electronic health record tool to detect AKI. All adult residents (18 years of age and older) of Olmsted County, Minnesota (MN), admitted to the Mayo Clinic Hospital between 2006 and 2014 were included. The incidence rate of AKI was calculated and temporal trends in the annual AKI incident rates assessed. During the nine-year study period, 10,283, and 41,847 patients were admitted to the intensive care unit or general ward, with 1,740 and 2,811 developing AKI, respectively...

OBJECTIVE: Surgical site infection (SSI) after open lower extremity bypass (LEB) is a serious complication leading to an increased rate of graft failure, hospital readmission, and health care costs. This study sought to identify predictors of SSI after LEB for arterial occlusive disease and also potential modifiable factors to improve outcomes. METHODS: Data from a statewide cardiovascular consortium of 35 hospitals were used to obtain demographic, procedural, and hospital risk factors for patients undergoing elective or urgent open LEB between January 2012 and June 2015...

Dialysis or kidney transplantation is the only therapeutic option for end stage renal disease. Accordingly, there is a large unmet clinical need for new causative therapeutic treatments. Obtaining robust models that mimic the complex nature of the human kidney is a critical step in the development of new therapeutic strategies. Here we establish a synthetic in vitro human renal tubulogenesis model based on a tunable glycosaminoglycan-hydrogel platform. In this system, renal tubulogenesis can be modulated by the adjustment of hydrogel mechanics and degradability, growth factor signaling, and the presence of insoluble adhesion cues, potentially providing new insights for regenerative therapy...

PURPOSE: In peritoneal dialysis (PD) patients, body fluid homeostasis is dependent on peritoneal elimination of water and solutes. Patients with less favorable peritoneal transport parameters should be more overhydrated. Despite this, the association between faster transport and overhydration (OH) is weak, and the factors that influence hydration status are still poorly characterized. Modified peritoneal equilibration tests (PET) offer us new parameters that might correlate better with hydration status, like free water transport (FWT)...

We report the case of a patient with pleural effusion occurring after initiation of a peritoneal dialysis. This phenomenon is favoured by the existence of a pleuroperitoneal communication. The latter is described at the origin of other diseases like catamenial pneumothorax and pleural effusion in connection with cirrhotic ascites. We describe this rare complication of peritoneal dialysis in order to draw attention of nephrologists, pulmonologists and surgeons.

Recently developed high-flux (HF) dialysis membranes with extended permeability provide better clearance of middle-sized molecules such as interleukins (ILs). Whether this modulation of inflammation influences the procalcific effects of septic plasma on vascular smooth muscle cells (VSMCs) is not known. To assess the effects of high cut-off (HCO) and medium cut-off (MCO) membranes on microinflammation and in vitro vascular calcification we developed a miniature dialysis model. Plasma samples from lipopolysaccharide-spiked blood were dialyzed with HF, HCO, and MCO membranes in an in vitro miniature dialysis model...

The placement of a peritoneal dialysis (PD) catheter by interventionalists demands not only procedural skill but also an ability to decipher real-time ultrasonographic and fluoroscopic images. In this article, we discuss how imaging assists in PD placement and recognition of complications. To aid this endeavor, we have provided images and video clips that should assist interventionalists. Compared with the fluoroscopic technique, peritoneoscopic PD catheter placement provides direct visual imaging to also aid placement of the initial trocar and the peritoneal catheter...

PURPOSE: Hemodialysis patients have extremely increased cardiovascular mortality. The coronary artery calcification score (CACS) in uremic patients receiving hemodialysis reflects the severity of atherosclerotic vascular disease and predicts the cardiovascular events. In cardiac conditions, left atrial (LA) size has a prognostic importance. In this study, relationship between coronary artery calcification and left atrial size was investigated. METHODS: This was a cross-sectional study involving 32 hemodialysis patients (16 females, 16 males; mean age, 52...

BACKGROUND AND OBJECTIVES: Although arteriovenous fistulas have been found to be the most cost-effective form of hemodialysis access, the relative benefits of placing an arteriovenous fistula versus an arteriovenous graft seem to be least certain for older adults and when placed preemptively. However, older adults' life expectancy is heterogeneous, and most patients do not undergo permanent access creation until after dialysis initiation. We evaluated cost-effectiveness of arteriovenous fistula placement after dialysis initiation in older adults as a function of age and life expectancy...

BACKGROUND AND OBJECTIVES: People receiving hemodialysis to treat kidney failure need a vascular access (a fistula, a graft, or a central venous catheter) to connect to the blood purification machine. Higher rates of access complications are considered the mechanism responsible for the excess mortality observed among catheter or graft users versus fistula users. We tested this hypothesis using mediation analysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We studied incident patients who started hemodialysis therapy from North America, Europe, and Australasia (the Dialysis Outcomes and Practice Patterns Study; 1996-2011)...

The sorption capacity of arabinan-rich pectic polysaccharide (ARPP) onto ferulic acid (FA) was investigated using equilibrium dialysis assays. UV and FT-IR spectra showed that FA was successfully adsorbed by ARPP. The effects of temperature, pH, buffer concentration, NaCl, and ethanol on sorption were investigated. Sorption variable optimization was examined by response surface methodology. The order of influence of each factor in affecting the sorption capacity was temperature>pH>buffer concentration...

The eradication of tuberculosis disease requires drug regimens that can penetrate the multiple layers of complex pulmonary lesions. Drug distribution in the caseous cores of cavities and lesions is especially crucial because they harbor subpopulations of drug-tolerant bacteria also commonly referred to as persisters. Existing methods for the measurement of drug penetration in tuberculosis lesions involve costly and time-consuming in vivo pharmacokinetic studies coupled to bioanalytical or imaging techniques...
