Encapsulating peritoneal sclerosis (EPS) is a rare but severe complication of dialysis (PD) characterized by extensive fibrosis the peritoneum. Changes in water transport may precede EPS, mechanisms and potential predictive value that defect are unknown. Among 234 patients with ESRD who initiated PD at our institution over 20-year period, 7 subsequently developed EPS. We evaluated changes time on these 28 matched controls using 3.86% glucose equilibration tests. Compared long-term controls,...

Variability in ultrafiltration influences prescriptions and outcomes patients with kidney failure who are treated peritoneal dialysis. Variants AQP1, the gene that encodes archetypal water channel aquaporin-1, may contribute to variability.We gathered clinical genetic data from 1851 dialysis seven cohorts determine whether AQP1 variants were associated a risk of composite death or technique (i.e., transfer hemodialysis). We performed studies cells, mouse models, samples obtained humans...

Abstract BACKGROUND. The study aimed to compare the cost‐effectiveness of concomitant and adjuvant temozolomide (TMZ) for treatment newly diagnosed glioblastoma multiforme versus initial radiotherapy alone from a public health care perspective. METHODS. economic evaluation was performed alongside randomized, multicenter, phase 3 trial. primary endpoint trial overall survival. Costs included all direct medical costs. Economic data were collected prospectively subgroup 219 patients (38%). Unit...

Most guidelines consider FDG PET-CT to detect occult extra-pulmonary disease prior lung metastasectomy. A cost-effectiveness analysis, using a Markov model over 10 year period, was performed compare two different surveillance programs, either or whole-body CT, in patients with suspected pulmonary metastasised melanoma.Data from published studies provided probabilities for the model. Complication and care costs were obtained standardised administrative databases 19 hospitals identified by DRG...

Although superior vena cava (SVC) stenosis may be a life-threatening complication of haemodialysis (HD) catheters, its prevalence and risk factors in HD patients are unknown. Our aim was to assess the for SVC with tunnelled cuffed catheter (TCC) describe clinical presentation.In this single-centre, retrospective cohort study, all in-centre chronic carrying TCC (1 January 2008-31 December 2012) were included (n = 117 patients, 214 TCC, 80 911 catheter-days). defined as diameter reduction >50%...

Fat accumulation in skeletal muscle was recently established as a major risk factor for cardiovascular disease (CVD) the general population, but its relevance patients with kidney failure is unknown. Here we examined potential association between radiation attenuation (MRA), non-invasive indicator of fat deposits muscle, and events treated peritoneal dialysis (PD) investigated dynamic changes determinants MRA this population. We retrospectively assessed on computed tomography images...

Chronic pancreatitis may lead to steatorrhea, enteric hyperoxaluria, and kidney damage. However, the prevalence determinants of hyperoxaluria in chronic patients as well its association with renal function decline have not been investigated. We performed an observational study. Urine oxalate creatinine ratio was assessed on 2 independent random urine samples consecutive adult followed at outpatient clinic from March 1 October 31, 2012. Baseline characteristics annual estimated glomerular...
