Our research broadens the knowledge of kidney disease.
Training Nephrology Fellows in Temporary Hemodialysis Catheters and Kidney Biopsies Is Not Needed and Should Not Be Required.
This opinion piece argues against the training of all nephrology fellows in the United States in our profession’s two major procedures: dialysis catheter insertion and percutaneous kidney biopsies. [...] regardless of who is placing the line or performing the kidney biopsy, nephrologists are integral in the care team because of the kidney, dialysis, and transplant expertise that only we can provide. In my mind, these two nephrology procedures are therefore not an essential part of what it means to be a nephrologist in 2018.
Glomerular disease augments kidney accumulation of synthetic anionic polymers
Polymeric drug carriers can alter the pharmacokinetics of their drug cargoes, thereby improving drug therapeutic index and reducing side effects. Understanding and controlling polymer properties that drive tissue-specific accumulation is critical in engineering targeted drug delivery systems. For kidney disease applications, targeted drug delivery to renal cells that reside beyond the charge- and size-selective glomerular filtration barrier could have clinical potential.
Serum 25-Hydroxyvitamin D Concentrations Are Associated with Computed Tomography Markers of Subclinical Interstitial Lung Disease among Community-Dwelling Adults in the Multi-Ethnic Study of Atherosclerosis (MESA)
Activated vitamin D has anti-inflammatory properties. 25-Hydroxyvitamin D [25(OH)D] deficiency might contribute to subclinical interstitial lung disease (ILD). We examined associations between serum 25(OH)D concentrations and subclinical ILD among middle-aged to older adults who were free of cardiovascular disease at baseline
Are we underestimating the quality of aviremic hepatitis C-positive kidneys? Time to reconsider
Kidney Donor Risk Index (KDRI) introduced in 2009 included hepatitis C serologic but not viremic status of the donors. With nucleic acid amplification testing (NAT) now being mandatory, further evaluation of these donors is possible. We conducted a retrospective matched case-control analysis of adult deceased donor kidney transplants...
A wearable artificial kidney for patients with end-stage renal disease
Stationary hemodialysis machines hinder mobility and limit activities of daily life during dialysis treatments. New hemodialysis technologies are needed to improve patient autonomy and enhance quality of life. We conducted a FDA-approved human trial of a wearable artificial kidney, a miniaturized, wearable hemodialysis machine, based on dialysate-regenerating sorbent technology. We aimed to determine the efficacy of the wearable artificial kidney in achieving solute, electrolyte, and volume homeostasis in up to 10 subjects over 24 hours.
Bioelectrical Impedance Analysis Measures and Clinical Outcomes in CKD
Bioelectrical impedance analysis (BIA) provides a noninvasive assessment of body composition. BIA measures of cell integrity (phase angle) and hydration (vector length) have been associated with mortality among patients receiving dialysis. Whether these measures are associated with clinical outcomes in patients with chronic kidney disease (CKD) is unknown.
GDF-15, Galectin 3, Soluble ST2, and Risk of Mortality and Cardiovascular Events in CKD
Inflammation, cardiac remodeling, and fibrosis may explain in part the excess risk for cardiovascular disease (CVD) in patients with chronic kidney disease (CKD). Growth differentiation factor 15 (GDF-15), galectin 3 (Gal-3), and soluble ST2 (sST2) are possible biomarkers of these pathways in patients with CKD
Heroin Use Is Associated with AA-Type Kidney Amyloidosis in the Pacific Northwest
AA-type kidney amyloidosis is classically associated with chronic autoimmune or inflammatory disorders. However, some urban centers have reported a high prevalence of injection drug use among patients with kidney AA amyloidosis. Previous reports lack control groups to quantify associations and most predate the opioid epidemic in the United States.
Hospice Use And End-Of-Life Spending Trajectories In Medicare Beneficiaries On Hemodialysis
Infrequent and late referral to hospice among patients on dialysis likely reflects the impact of a Medicare payment policy that discourages the concurrent receipt of these services, but it may also reflect these patients’ less predictable illness trajectories. Among a national cohort of patients on hemodialysis, we identified four distinct spending trajectories during the last year of life that represented markedly different intensities of care.
Willingness to Consider Increased-Risk Donors: A Single-Center Experience in Kidney Transplantation
The number of Public Health Service increased-risk organ donors (PHS IRD) is growing, largely from an increase in intravenous drug use overdoses due to the current opioid epidemic.
