A pilot, single-blinded, randomized cross-over trial of cramp reduction with angiotensin II in maintenance patients on hemodialysis (The CRAMP-HD study).

Introduction: Angiotensin II may reduce muscle ischemia during intermittent hemodialysis and thereby decrease the incidence and/or intensity of intradialytic muscle cramps. We aimed to test whether angiotensin II infusion during intermittent hemodialysis is safe, feasible, and effective in the attenuation of muscle cramps.

Methods: We performed a pilot, single-blinded, randomized crossover trial of patients receiving intermittent hemodialysis who frequently experience intradialytic muscle cramps.

A Pilot and Feasibility Study of Continuous Cardiac Output and Blood Pressure Monitoring during Intermittent Hemodialysis.

Introduction: Hypotension is common during intermittent hemodialysis (IHD) and may be due to a decreased cardiac index (CI). However, no study has simultaneously and continuously measured CI and mean arterial pressure (MAP) to understand the prevalence, severity, and duration of CI decreases or relate them to MAP, blood volume (BV), and net ultrafiltration (NUF) rate.

Methods: In a prospective, pilot and feasibility investigation, we studied 10 chronic IHD patients.

The AMPK activator ATX-304 alters cellular metabolism to protect against cisplatin-induced acute kidney injury.

Acute kidney injury (AKI) disrupts energy metabolism. Targeting metabolism through AMP-activated protein kinase (AMPK) may alleviate AKI. ATX-304, a pan-AMPK activator, was evaluated in C57Bl/6 mice and tubular epithelial cell (TEC) cultures.

Cardiac Output Changes during Renal Replacement Therapy: A Scoping Review.

Introduction: Renal replacement therapy (RRT) is associated with hypotension. However, its impact on cardiac output (CO) is less understood. We aimed to describe current knowledge of CO monitoring and changes during RRT.

Expression of NEDD4L and ENaC in Urinary Extracellular Vesicles in Pre-eclampsia.

Objective: To assess changes in expression of renal epithelial sodium channel (ENaC) and NEDD4L, a ubiquitin ligase, in urinary extracellular vesicles (UEV) of pre-eclamptic women compared to normal pregnant controls.

Methods: Urine was collected from pre-eclamptic women (PE,  = 20) or during normal pregnancy (NP,  = 20). UEV were separated by differential ultracentrifugation.
