INTRODUCTION Acute kidney injury (AKI) can evolve quickly and clinical measures of function often fail to detect AKI at a time when interventions are likely to provide benefit. Identifying early markers of kidney damage has been difficult due to the complex nature of human AKI, in which multiple etiologies exist. The objective of this study was to identify(More)
Cytosine methylation is required for mammalian development and is often perturbed in human cancer. To determine how this epigenetic modification is distributed in the genomes of primary and transformed cells, we used an immunocapturing approach followed by DNA microarray analysis to generate methylation profiles of all human chromosomes at 80-kb resolution(More)
BACKGROUND Neutrophil gelatinase-associated lipocalin (NGAL) appears to be a promising biomarker for the early diagnosis of acute kidney injury (AKI); however, a wide range in its predictive value has been reported. STUDY DESIGN Meta-analysis of diagnostic test studies using custom-made standardized data sheets sent to each author. SETTING & POPULATION(More)
INTRODUCTION During critical illness, oliguria is often used as a biomarker of acute kidney injury (AKI). However, its relationship with the subsequent development of AKI has not been prospectively evaluated. METHODS We documented urine output and daily serum creatinine concentration in patients admitted for more than 24 hours in seven intensive care(More)
OBJECTIVES The aim of this study was to test the hypothesis that, without diagnostic changes in serum creatinine, increased neutrophil gelatinase-associated lipocalin (NGAL) levels identify patients with subclinical acute kidney injury (AKI) and therefore worse prognosis. BACKGROUND Neutrophil gelatinase-associated lipocalin detects subclinical AKI hours(More)
OBJECTIVE To compare the value of novel with conventional serum biomarkers in the prediction of acute kidney injury (AKI) in adult cardiac surgical patients according to preoperative renal function. DESIGN Single-center, prospective observational study. SETTING Tertiary hospital. PATIENTS One hundred adult cardiac surgical patients. MEASUREMENTS AND(More)
BACKGROUND The purpose of this study was to investigate the ability of neutrophil gelatinase-associated lipocalin (NGAL), cystatin C, and their combination in predicting the duration and severity of acute kidney injury (AKI) after cardiac surgery in adults. METHODS Using data from a prospective observational study of 100 adult cardiac surgical patients,(More)
OBJECTIVE Sepsis is the most common trigger for acute kidney injury (AKI) in critically ill patients. We sought to determine whether there are unique patterns to plasma and urine neutrophil gelatinase-associated lipocalin (NGAL) in septic compared with non-septic AKI. DESIGN Prospective observational study. SETTING Two adult ICUs in Melbourne,(More)
Acute kidney injury (AKI) commonly occurs in hospitalized patients and is independently and strongly associates with morbidity and mortality. The clinical benefits of a timely and definitive diagnosis of AKI have not been fully realized due to limitations imposed by the use of serum creatinine and urine output to fulfill diagnostic criteria. These(More)
BACKGROUND Preliminary evidence suggests a nephroprotective effect of urinary alkalinization in patients at risk of acute kidney injury. In this study, we tested whether prophylactic bicarbonate-based infusion reduces the incidence of acute kidney injury and tubular damage in patients undergoing open heart surgery. METHODS AND FINDINGS In a multicenter,(More)
