INTRODUCTION: Kidney Disease Improving Global Outcomes (KDIGO) guidelines recommend vitamin D supplementation in hemodialyzed patients to monitor 25(OH)-vitamin D 25(OH)D levels. However, patient-to-patient inconsistency can be observed in response to the treatment. In this study, we aimed to evaluate the impact of the dialysis membrane on 25(OH)D, albumin (Alb) and vitamin D-binding protein (VDBP), the major players of vitamin D transport and storage. MATERIAL AND METHODS: Alb (Cobas), VDBP (R&D) and 25(OH)D (liquid chromatography-tandem mass spectrometry) were measured in 75 patients before and after a 4-hour dialysis session...

Our previous studies demonstrated that a bioprocessed polysaccharide (BPP) isolated from Lentinus edodes mushroom mycelia cultures supplemented with black rice bran can protect mice against Salmonella lipopolysaccharide-induced endotoxemia and reduce the mortality from Salmonella Typhimurium infection through upregulated T-helper 1 immunity. Here, we report that a BPP from L. edodes mushroom mycelia liquid cultures supplemented with turmeric (referred to as BPP-turmeric) alters chicken macrophage responses against avian-adapted Salmonella Gallinarum and protects chicks against a lethal challenge from Salmonella Gallinarum...

The relationship between the surface Electromyogram (sEMG) signal and the force of an individual muscle is still ambiguous due to the complexity of experimental evaluation. However, understanding this relationship should be useful for the assessment of neuromuscular system in healthy and pathological contexts. In this study, we present a global investigation of the factors governing the shape of this relationship. Accordingly, we conducted a focused sensitivity analysis of the sEMG/force relationship form with respect to neural, functional and physiological parameters variation...

PURPOSE: Hemodialysis (HD) patients who are female or black receive fewer arteriovenous fistulas (AVF) and more grafts (AVG). We evaluated race- and sex-based differences for three process exposures: access surgery, peripherally-inserted central catheters (PICCs), and vascular imaging. METHODS: US Renal Data System with linked Medicare claims for patients initiating HD between April 2010 - December 2011 were used to identify PICC placement, imaging, AVF and AVG surgeries, and the vascular accesses in use at individual HD treatments...

INTRODUCTION: Multiple factors and comorbidities have been implicated in the ability of arteriovenous fistulas (AVF) to mature, including vessel anatomy, advanced age, and the presence of coronary artery disease or peripheral vascular disease. However, little is known about the role of uremia on AVF primary failure. In this study, we attempt to evaluate the effect of uremia on AVF maturation by comparing AVF outcomes between pre-dialysis chronic kidney disease (CKD) stage five patients and those who had their AVF created after hemodialysis (HD) initiation...

Sleep disturbance is a frequent and serious complication of hemodialysis (HD). Low serum vitamin D levels have been associated with sleep quality in non-HD subjects. Our aim was to examine the possible association between serum vitamin D levels and the presence of sleep disturbance in HD patients. We recruited 141 HD patients at the HD center of the First Affiliated Hospital of Jiaxing University during 2014-2015. Serum levels of 25-hydroxyvitamin D (25(OH)D) were determined by the competitive protein-binding assay...

BACKGROUND AND OBJECTIVE: Progress in endoscopic surgery in the past few decades has led to the application of 3-dimensional (3D) procedures in operating rooms. This permits patient- and surgeon-friendly operations and also maximizes the superiority of laparoscopy over laparotomy. In this study, we compare 2-dimensional (2D) and 3D endoscopy techniques with regard to time, efficiency, optics, and handling by users with different degrees of experience at 4 difficulty levels. DESIGN: A randomized controlled trial on a pelvitrainer in objectively graded surgical steps for students and postgraduates...

OBJECTIVE: Protein energy wasting (PEW) is consistently associated with poor prognosis in hemodialysis (HD) patients. We compared the predictability of PEW as diagnosed by The International Society of Renal Nutrition and Metabolism criteria (PEWISRNM) and geriatric nutritional risk index (GNRI) for all-cause mortality in Japanese HD patients. As cut-off values for body mass index (BMI) for PEW have not been established in PEWISRNM for Asian populations, these were also investigated. DESIGN AND SUBJECTS: The nutritional status from 409 HD patients was evaluated according to ISRNM and GNRI criteria...

Histone deacetylases (HDACs) are epigenetic enzymes creating the transcriptionally inactive state of chromatin by erasing acetyl moiety from histone and non-histone substrates. HDAC6 modulates several biological pathways in dividing cells as well as in post-mitotic neurons, and has been implicated in the pathophysiology of neurodegeneration. The distinct cellular functions and survival in these cells are reliant on HDAC6-mediated processes including intracellular trafficking, chaperone-mediated stress responses, anti-oxidation and protein degradation...

Children with ESRD in need of RRT are commonly managed by PD due to difficulty with vascular access for HD and the relatively large extracorporeal blood volume required. Major abdominal surgery may result in injury to the peritoneum and consequent adhesion, thereby resulting in a reduction in the anatomical capacity and transport capability across the peritoneal membrane. Here, we report successful resumption of PD after LDLT in two pediatric patients. The causes of ESRD were PH1 and juvenile nephronophthisis, respectively...

Huntington's disease (HD) is caused by a mutation in the huntingtin gene (HTT), resulting in profound striatal neurodegeneration through an unknown mechanism. Perturbations in the urea cycle have been reported in HD models and in HD patient blood and brain. In neurons, arginase is a central urea cycle enzyme, and the metal manganese (Mn) is an essential cofactor. Deficient biological responses to Mn, and reduced Mn accumulation have been observed in HD striatal mouse and cell models. Here we report in vivo and ex vivo evidence of a urea cycle metabolic phenotype in a prodromal HD mouse model...

OBJECTIVES: Differentiating malignant pleural mesothelioma (MPM) from reactive mesothelial hyperplasia (RMH) is still challenging. Detection of homozygous deletion (HD) of 9p21 region including p16(INK4A) (p16) by fluorescence in situ hybridization (FISH) and immunohistochemical detection of loss of BRCA1 associated protein 1 (BAP1), are reliable markers for MPM diagnosis. However, not all laboratories are equipped to perform 9p21 FISH; immunohistochemistry (IHC) is a more common and feasible technique...
