Survey of urinary nickel in peritoneal dialysis patients.

This study surveyed urinary nickel concentrations in peritoneal dialysis (PD) patients, and analyzed the association of urinary nickel concentrations with clinical outcomes and inflammatory biomarkers. In total, 50 PD patients and 50 healthy controls were recruited for this study. All participants were examined for the presence of toxic trace elements (antimony, arsenic, bismuth, cadmium, copper, manganese, mercury, nickel, lead, tellurium, thallium and zinc) in their urine by using inductively coupled plasma mass spectrometry (ICP-MS).

Oral Tori in Chronic Peritoneal Dialysis Patients.

Background: The pathogenesis of oral tori has long been debated and is thought to be the product of both genetic and environmental factors, including occlusal forces. Another proposed mechanism for oral tori is the combination of biomechanical forces, particularly in the oral cavity, combined with cortical bone loss and trabecular expansion, as one might see in the early stages of primary hyperparathyroidism. This study investigated the epidemiology of torus palatinus (TP) and torus mandibularis (TM) in peritoneal dialysis patients, and analyzed the influences of hyperparathyroidism on the formation of oral tori.

Dual-incision laparoscopic surgery for peritoneal dialysis catheter implantation and fixation: a novel, simple, and safe procedure.

Background: Peritoneal dialysis (PD) is an alternative modality to hemodialysis and is usually used to treat patients with end-stage renal disease. Dual-incision laparoscopic surgery (DILS) had been reported in several surgical fields; however, no report was proposed about DILS in PD catheter implantation (DILS-PD). In this study, we present DILS with a novel, simple, and safe procedure for PD catheter implantation with fixation and describe the long-term outcome.

Cardiothoracic ratio association with mortality in patients on maintenance peritoneal dialysis.

The cardiothoracic ratio (CTR) indicates the left ventricular size; however, the significance of the CTR in patients on maintenance peritoneal dialysis (PD) remains unclear. In this study, 335 PD patients were enrolled and demographic, biochemical, co-morbidity, and dialysis-related data were obtained. The factors determining CTR were further analyzed.

Glycated hemoglobin predicts mortality in nondiabetic patients receiving chronic peritoneal dialysis.

Background: patients with chronic peritoneal dialysis (CPD) use glucose-based dialysate to maintain their life; however, whether the glycemic status influences outcome of these patients without diabetes remains unknown.

Methods: we conducted a cross-sectional and 18-month prospective study, and 269 nondiabetic patients with CPD were enrolled in a medical center. Glycated hemoglobin (HbA1c) levels were measured at baseline and categorized in tertiles of HbA1c: high (>5.

Protein nutrition index as a function of patient survival rate in peritoneal dialysis.

Background/aims: Protein-energy wasting (PEW) is a well-known risk factor of long-term survival in peritoneal dialysis (PD) patients. Serum albumin is a measure of visceral protein, lean body mass is a measure of somatic protein stores and normalized protein nitrogen appearance is a measure of daily protein intake. A protein nutrition index (PNI) that combined these 3 factors was designed and tested as a function of survival in PD patients.
