INTRODUCTION These analyses examine: a) survival from the start of renal replacement therapy (RRT); b) survival amongst all prevalent dialysis patients alive on 31st December 2011; c) the cause of death for incident and prevalent patients and d) the projected life years remaining for patients starting RRT. Changes in survival between the 1997 and 2011 cohort are also reported. METHODS Surviva...
For in vivo studies of influenza dynamics where within-host measurements are fit with a mathematical model, infectivity assays (e.g. 50% tissue culture infectious dose; TCID50) are often used to estimate the infectious virion concentration over time. Less frequently, measurements of the total (infectious and non-infectious) viral particle concentration (obtained using real-time reverse transcri...
BACKGROUND Autosomal dominant polycystic kidney disease (ADPKD) is the fourth most common renal disease requiring renal replacement therapy (RRT). Still, there are few epidemiological data on the prevalence of, and survival on RRT for ADPKD. METHODS This study used data from the ERA-EDTA Registry on RRT prevalence and survival on RRT in 12 European countries with 208 million inhabitants. We s...
Critically ill patients whose course is complicated by acute kidney injury often receive renal replacement therapy (RRT). For these patients, initiation of RRT results in a considerable escalation in both the complexity and associated cost of care. While RRT is extensively used in clinical practice, there remains uncertainty about the ideal circumstances of when to initiate RRT and for what ind...
BACKGROUND Only a proportion of critically ill patients with severe [RIFLE (Risk, Injury, Failure, Loss, End-stage renal disease) criteria, class-F] acute kidney injury (AKI) appear to receive renal replacement therapy (RRT). The aim of this study was to study the characteristics and outcome of patients with severe (RIFLE-F) AKI who did not receive RRT. METHODS We identified all consecutive p...
Although the use of renal replacement therapy (RRT) to support critically ill patients with acute kidney injury (AKI) has become routine, many of the fundamental questions regarding optimal management of RRT remain. This review summarizes current evidence regarding the timing of initiation of RRT, the selection of the specific modality of RRT, and prescription of the intensity of therapy. Altho...
AIMS The aim of this study was to assess the prognostic value of chronic kidney disease (CKD) in relation to ischaemic stroke, intracranial haemorrhage, major bleeding, and all-cause death in heart failure patients without atrial fibrillation. METHODS AND RESULTS In this observational cohort study, heart failure patients without atrial fibrillation were identified using Danish nationwide regi...
BACKGROUND Guatemala is the country with the largest swine production in Central America; however, evidence of influenza A virus (IAV) in pigs has not been clearly delineated. OBJECTIVES In this study, we analyzed the presence and spatial distribution of IAV in commercial and backyard swine populations. METHODS Samples from two nationwide surveys conducted in 2010 and 2011 were tested using...
Clinicians frequently use influenza rapid antigen tests for diagnostic testing. We tested nasal wash samples from 1 April to 7 June 2009 from 1538 patients using the QuickVue Influenza A+B (Quidel) rapid influenza antigen test and compared the results with real-time reverse transcription polymerase chain reaction (rRT-PCR) assay (gold standard). The prevalence of 2009 pandemic influenza A (pH1N...
Sampling-based algorithms for path planning have achieved great success during the last 15 years, thanks to their ability to efficiently solve complex high-dimensional problems. However, standard versions of these algorithms cannot guarantee optimality or even high-quality for the produced paths. In recent years, variants of these methods, taking cost criteria into account during the exploratio...
