The rate of change of the serum creatinine concentrations in 63 patients with chronic progressive renal disease of varied etiology was examined by linear regression analysis using the logarithm or the reciprocal of the serum creatinine concentration versus time. A single straight line was described by one or the other of these relationships in 53 patients. Six patients had an accelerated rate of nephron destruction terminally (two slopes) regardless of the mathematical analysis. The remaining four patients had course changes either due to apparent spontaneous remissions or temporally related to therapy. These data suggest that (functional) nephron loss in chronic progress disease is orderly and mathematically definable. The theoretical implications are that functional nephron loss is either exponential (log Cr) or constant (1/Cr).

Spaceflight-induced multi-organ dysfunction affects the health of astronauts and the safety of in-orbit flight. However, the effect of microgravity on the kidney and the underlying mechanisms are unknown. In the current study, we used a hindlimb unweighting (HU) animal model to simulate microgravity and employed histological analysis, ischemia-reperfusion experiments, renal ultrasonography, bioinformatics analysis, isometric force measurement, and other molecular experimental settings to evaluate the effects of microgravity on the kidneys and the underlying mechanisms involved in this transition.

Glomerular filtration rate (GFR) as a marker of kidney function is important in health and disease management because decreased kidney function is associated with all-cause and cardiovascular mortality, progression of kidney disease, predisposition to acute kidney injury (AKI), and for drug dosage modification. While measured glomerular filtration rate (mGFR) is acknowledged as the most accurate method for evaluating kidney function, it is at present not feasible to be applied in the clinical arena. Estimated glomerular filtration rate (eGFR) is preferred due to its convenience, cost-effectiveness, and seamless integration into standard clinical practice for kidney function evaluation.

Background: Primary aldosteronism (PA) is the leading surgically treatable cause of hypertension, with adrenalectomy as the definitive treatment for unilateral PA (UPA). However, some patients have persistent hypertension after surgery. This study aims to identify preoperative factors affecting surgical outcomes and develop a predictive model for postoperative hypertension resolution.

Background: Inadequate treatment of acute rejection (AR) in pediatric kidney transplant recipients (KTR) can contribute to early allograft failure. Serum creatinine is an insensitive marker of allograft function, especially in the pediatric population, and may not detect ongoing rejection after treatment. We evaluated the utility of follow-up biopsies to detect persistent inflammation and future episodes of rejection.

Objectives: Serum galectin-3 (sGal-3) is a protein present in renal tubules and increases in experimental rodent models of acute kidney injury. The aim of this study was to compare sGal-3 concentrations in healthy cats and cats with ureteral obstruction (UO).
Methods: This was a retrospective study.
