IMPORTANCE Rhabdomyolysis ranges in severity from asymptomatic elevations in creatine phosphokinase levels to a life-threatening disorder characterized by severe acute kidney injury requiring hemodialysis or continuous renal replacement therapy (RRT). OBJECTIVE To develop a risk prediction tool to identify patients at greatest risk of RRT or in-hospital(More)
Genome-wide association studies (GWASs) have identified multiple loci associated with cross-sectional eGFR, but a systematic genetic analysis of kidney function decline over time is missing. Here we conducted a GWAS meta-analysis among 63,558 participants of European descent, initially from 16 cohorts with serial kidney function measurements within the(More)
PURPOSE To investigate the association between potassium concentration at the initiation of critical care and all-cause mortality. METHODS We performed a retrospective observational study on 39,705 patients, age ≥18 years, who received critical care between 1997 and 2007 in two tertiary care hospitals in Boston, Massachusetts. The exposure of interest was(More)
BACKGROUND AND OBJECTIVES At least four definitions of AKI have recently been proposed. This study sought to characterize the epidemiology of AKI according to the most recent consensus definition proposed by the Kidney Disease Improving Global Outcomes (KDIGO) Work Group, and to compare it with three other definitions.

The mammalian target of rapamycin (mTOR) plays a key role in the immune response. mTOR inhibitors suppress T cell activation and proliferation and are effective immunosuppressants. Today there is growing interest in their potential role in inducing tolerance after transplantation. mTOR inhibitors induce anergy in naïve T cells, promote the expansion of(More)
BACKGROUND In the US, native kidney biopsies are usually inpatient procedures. We developed an outpatient biopsy protocol for low-risk patients and assessed its safety and efficacy. METHODS Patients with an SBP <140 mm Hg and a BMI ≤35 who were not taking anticoagulants, ASA and NSAIDS in the preceding week were included. Biopsies were performed under(More)
Early identification of CKD risk factors may allow risk factor modification and prevention of CKD progression. We investigated the hypothesis that risk factors are present ≥30 years before the diagnosis of CKD in a case-control study using data from the Framingham Offspring Study. Patients with incident CKD (eGFR≤60 ml/min per 1.73 m2) at examination cycles(More)
BACKGROUND Albuminuria is an important risk factor for cardiovascular disease (CVD). We have previously identified a missense single-nucleotide polymorphism (rs1801239) in the CUBN gene that is associated with albuminuria. Whether albuminuria is associated with CVD in the presence of the CUBN mutation is unknown. METHODS We analyzed participants from the(More)
BACKGROUND AND OBJECTIVES There is a projected shortage of kidney specialists, and retention of trainees in nephrology is important. Determining factors that result in choosing a nephrology career could inform future strategies to attract nephrology fellows. DESIGN, SETTINGS, PARTICIPANTS, & MEASUREMENTS An anonymous, internet-based survey was sent to(More)
