Expanded hemodialysis (HDx) provides increased clearance of conventional and large middle molecules through innovative medium cutoff (MCO) membranes. However, there is a paucity of real-world data regarding the benefits and safety of HDx. This large observational study evaluated outcomes among patients in Colombia undergoing HDx at a extended dialysis clinical services provider. This was a prospective single cohort study of prevalent patients who were treated with HDx; baseline information was collected from the most recent data before patients were started on HDx...

INTRODUCTION: Lateral epicondylalgia (LE) is a musculoskeletal injury involving the common extensor origin in elbow manifesting as pain and ineffective handgrip affecting the daily activities of the individuals with LE. OBJECTIVES: This study determined the effectiveness of Standard Biomechanical Taping (SBMT), Vector Correcting Dysfunction Techniques 1 (VCDT 1) and Vector Correcting Dysfunction Technique 2 (VCDT 2); and compared their differences on effects on pain, grip strength and daily functions of individual with unilateral LE...

Membranoproliferative glomerulonephritis is known to recur after kidney transplantation and may lead to allograft loss. Although an optimal treatment has not been determined, B-cell targeted therapies are now increasingly used as first-line agents, based on growing data showing antibodies as key players in the pathogenesis of membranoproliferative glomerulonephritis. Here, we report a case of recurrent immune complex-mediated membranoproliferative glomerulonephritis 3 years after a living-donor kidney transplant...

BACKGROUND: The kinetics of β2-microglobulin during hemodialysis and hemodiafiltration is well described by a two-compartment model where clearance by the dialyzer is from a central compartment volume that approximates plasma volume and a total distribution volume that approximates extracellular fluid volume. The kinetics of middle molecules with molecular weights larger than β2-microglobulin have not been extensively studied. METHODS: Intradialytic plasma concentrations and overall dialyzer clearances of β2-microglobulin (11...

Hemodiafiltration (HDF) increases the removal of middle-molecular-weight uremic toxins and may improve outcomes in patients with end-stage kidney disease (ESKD), but it requires complex equipment and comes with risks associated with infusion of large volumes of substitution solution. New high-flux hemodialysis membranes with improved diffusive permeability profiles do not have these limitations and offer an attractive alternative to HDF. However, both strategies are associated with increased albumin loss into the dialysate, raising concerns about the potential for decreased serum albumin concentrations that have been associated with poor outcomes in ESKD...

OBJECTIVE: There are some reports of cervical cancer with uterus didelphys but a case of clear cell carcinoma (CCCC) with Obstructed Hemivagina and Ipsilateral Renal Anomaly (OHVIRA) syndrome is extremely rare. The aim of this paper was to report a case of CCCC with OHVIRA syndrome and the difficulty in making a preoperative diagnosis. CASE REPORT: A 65 years old woman presented with postmenopausal bleeding and pelvic examination showed right paracervical mass. Preoperative confirmation of cervical carcinoma was difficult due to the location of the mass, which was inaccessible by cervical punch biopsy...

A pseudo-one compartment model has been proposed to describe phosphorus kinetics during hemodialysis and the immediate post-dialysis period. This model assumes that phosphorus mobilization from tissues is proportional to the difference between the pre-dialysis serum concentration (a constant) and the instantaneous serum concentration. The current study is exploratory and evaluated the ability of a pseudo-one compartment model to describe the kinetics of phosphorus during two short hemodialysis treatments separated by a 60-min inter-treatment period without dialysis; the latter is the post-dialysis rebound period for the first short hemodialysis treatment...

Renal cell carcinoma (RCC) has a high incidence in the kidney transplant population and annual surveillance detects these tumors early in their natural history. Minimal guidelines exist regarding RCC surveillance in ESRD patients awaiting transplant. A retrospective review of our kidney transplant database examined the outcomes of annual ultrasonographic surveillance during initial kidney transplant evaluation and upon annual reassessment. Of 2642 patients listed for transplant, 145 patients were found to have masses during initial kidney transplant evaluation or annual imaging consistent with new complex cystic disease or RCC...

Background: The VIVIA Hemodialysis System (Baxter Healthcare Corporation, Deerfield, IL, USA) was designed for patient use at home to reduce the burden of treatment and improve patient safety. It has unique features including extended use of the dialyzer and blood set through in situ hot-water disinfection between treatments; generation of on-line infusible-quality dialysate for automated priming, rinseback and hemodynamic support during hypotension and a fully integrated access disconnect sensor...

The concentration of hydrogen peroxide (H2O2) in blood and plasma is a measurement that has often been made, but the absolute values remain unsettled due the great variability of results actually published in the literature. As in every tissue, the concentration of H2O2 in blood and plasma is determined by the dynamics of its production versus its removal. The major sources of H2O2 in cells will only be briefly described as they are already well documented, The production of H2O2 in red blood cells will be described as it is less well known...

We report a late presentation of adenovirus-induced renal allograft and bladder infection causing azotemia and hemorrhagic cystitis in a patient 5 years after simultaneous kidney-pancreas transplantation. Adenovirus has been increasingly recognized as a cause of morbidity and mortality in both solid organ and stem cell transplant recipients. We wish to emphasize the importance of early detection, as treatment options involve reduction of immunosuppression, followed by the addition of antiviral agents and supportive care...

It is important to control daily diet, water intake and life style as well as monitor the quality of urine for urolithiasis prevention. For decades, many ion-related indices have been developed for predicting the formation of urinary stones or urolithiasis, such as EQUILs, relative supersaturation (RSS), Tiselius indices (TI), Robertson risk factor algorithms (RRFA) and more recently, the Bonn risk index. However, they mostly demand robust laboratory analysis, are work-intensive, and even require complex computational programs to get the concentration patterns of several urine analytes...

Laser microdissection (LMD) was utilized for the separation of the yolk, follicular wall (granulosa and theca), and surrounding stromal cells of small white follicles (SWF) obtained from reproductively active domestic fowl. Herein, we provide an in situ proteomics-based approach to studying follicular development through the use of LMD and mass spectrometry. This study resulted in a total of 2889 proteins identified from the three specific isolated compartments. White yolk from the smallest avian follicles resulted in the identification of 1984 proteins, while isolated follicular wall and ovarian stroma yielded 2470 and 2456 proteins, respectively...

The prescription of dialysate potassium concentration during short daily and long nocturnal (high dose) hemodialysis (HD) is challenging due to limited clinical experience with such modalities. The aim here is to propose a quantitative approach for prescribing dialysate potassium concentrations during high-dose HD. Potassium kinetic parameters based on a pseudo one-compartment model from 547 patients participating in the HEMO Study were used for prediction purposes in this study. Patients were categorized based on the prescribed dialysate potassium concentration during thrice weekly HD as 1K (mean of 1...

Ovarian cancer (OVC) remains the most lethal gynecological malignancy in the world due to the combined lack of early-stage diagnostics and effective therapeutic strategies. The development and application of advanced proteomics technology and new experimental models has created unique opportunities for translational studies. In this study, we investigated the ovarian cancer proteome of the chicken, an emerging experimental model of OVC that develops ovarian tumors spontaneously. Matched plasma, ovary, and oviduct tissue biospecimens derived from healthy, early-stage OVC, and late-stage OVC birds were quantitatively characterized by label-free proteomics...

With growing abundance and awareness of endocrine disrupting compounds (EDCs) in the environment, there is a need for accurate and reliable detection of EDC exposure. Our objective in the present study was to observe differences within and between the global plasma proteomes of sexually mature male and female white perch (Morone americana) before (Initial Control, IC) and after 17β-estradiol (E2 ) induction. Semiquantitative nanoLC-MS/MS data were analyzed by machine learning support vector machines (SVMs) and by two-way ANOVA...

The bZIP transcription factor, C/EBPα is highly inducible by UVB and other DNA damaging agents in keratinocytes. C/EBPα-deficient keratinocytes fail to undergo cell cycle arrest in G1 in response to UVB-induced DNA damage and mice lacking epidermal C/EBPα are highly susceptible to UVB-induced skin cancer. The mechanism through which C/EBPα regulates the cell cycle checkpoint in response to DNA damage is unknown. Here we report untreated C/EBPα-deficient keratinocytes have normal levels of the cyclin-dependent kinase inhibitor, p21, however, UVB-treated C/EBPα-deficient keratinocytes fail to up-regulate nuclear p21 protein levels despite normal up-regulation of Cdkn1a mRNA levels...

BACKGROUND: In 2012, the United States experienced one of its worst West Nile virus (WNV) epidemics, reporting 5,387 human cases and final death toll of 243. Texas was at the epicenter of the outbreak, with 1,875 reported cases and 89 deaths that year. The Texas outbreak centered mainly in the Dallas-Fort Worth area where 30 deaths were reported. We report three cases of severe WNV infection complicated by meningoencephalitis in our organ transplant population. METHODS: Clinical data were collected from chart review...
