Our research broadens the knowledge of kidney disease.
Utilization of Standard Criteria Donor and Expanded Criteria Donor Kidneys After Kidney Allocation System Implementation
Implementation of the Kidney Allocation System (KAS) changed how kidneys are allocated and the information on which organ utilization decisions are based. We aimed to evaluate how KAS implementation changed kidney utilization and recipient outcomes.
Urine Complement Proteins and the Risk of Kidney Disease Progression and Mortality in Type 2 Diabetes
We examined the association of urine complement proteins with progression to end-stage renal disease (ESRD) or death in people with type 2 diabetes and proteinuric diabetic kidney disease (DKD).
Clinical presentation at initiation of maintenance dialysis and subsequent survival: A retrospective cohort study
Clinical practice guidelines increasingly favor a more symptom-driven approach to maintenance dialysis initiation. But, little is known about the clinical presentation at dialysis initiation, such as the different kinds of signs and symptoms present at dialysis initiation, illness acuity at dialysis initiation, and how these aspects of the clinical presentation relate to subsequent survival.
Protecting kidneys in liver transplant patients: A pathway to preventive interventions
Acute kidney injury (AKI) is a frequent postoperative complication after liver transplantation. The etiology is multifactorial, including perioperative renal status, surgery related events, and postoperative immunosuppression therapy. The role of renal hypoperfusion and hepatic ischemia-reperfusion injury as causes of early AKI are now being increasingly recognized. Further studies should focus on therapies that would attenuate this injury.
GLP-1 Receptor Agonists in Diabetic Kidney Disease: from the Patient-Side to the Bench-Side
Diabetic kidney disease (DKD), one of the most common and severe microvascular complications of diabetes, is the leading cause of chronic kidney disease and end-stage kidney disease worldwide. This perspective summarizes clinical and experimental observations to give insight into biological mechanisms beyond glycemic control, such as natriuresis and anti-inflammatory actions, for preservation of kidney function in patients with diabetes.
Relation of multi-marker panel to incident chronic kidney disease and rapid kidney function decline in African Americans: the Jackson Heart Study
Few investigations have evaluated the incremental usefulness of multiple biomarkers representing varying physiological pathways for predicting risk of renal outcomes in African Americans. We related a multi-marker panel to incident chronic kidney disease (CKD) and rapid kidney function decline (RKFD) in 2813 Jackson Heart Study participants without prevalent CKD at exam 1 (2000-2004) and with complete assays at exam 1 for 9 biomarkers: adiponectin, aldosterone, B-natriuretic peptide [BNP], cortisol, high sensitivity C-reactive protein (hsCRP), endothelin, homocysteine, plasma renin activity and mass.
Identification of Acute Kidney Injury Sub-phenotypes with Differing Molecular Signatures and Response to Vasopressin Therapy
The aim of this study was to identify and test whether AKI sub-phenotypes have prognostic and therapeutic implications.
Association of Soluble TNFR-1 Concentrations with Long-Term Decline in Kidney Function: The Multi-Ethnic Study of Atherosclerosis
Higher soluble TNF receptor-1 (sTNFR-1) concentrations are associated with kidney disease progression among persons with established diabetic kidney disease. However, no studies have assessed sTNFR-1's role in long-term kidney function changes in a multiethnic population without cardiovascular disease at baseline.
Treatment of Hyponatremia in End-Stage Liver Disease: New Tools in the Shed
In a retrospective cohort of hospitalized patients with cirrhosis, the administration of intravenous albumin was associated with a higher rate of hyponatremia resolution and better 30-day survival. We are excited by this study because the data supports what we have long observed to be true—that albumin has an important role to play in mitigating a number of the pathophysiological underpinnings of hyponatremia in patients with cirrhosis.
Automated quantification of bioluminescence images
We developed a computer-aided analysis tool for quantitatively determining bioluminescent reporter distributions inside small animals. The core innovations are a body-fitting animal shuttle and a statistical mouse atlas, both of which are spatially aligned and scaled according to the animal’s weight, and hence provide data congruency across animals of varying size and pose.
