In 20, 40 and 60-day-old rats the filtration rate was studied using Baines modification of Hanssen's Na4Fe (14CN)6 method enabeling the determination of single nephron glomerular filtration rate (SNGFR) ratio between superficial (S), intercortical (I) and juxtamedullary (J) nephrons. The proximal tubule lengths were determined as well. A close correlation was obtained between age and S/I, I/J and S/J of proximal tubule lengths and between age and I/J, S/J 14C-activities of ferro-cyanide. Presented findings confirm the data on the increasing role of superficial nephrons in the course of postnatal development of rat.

Impact of estimated glomerular filtration rate (eGFR) on in-hospital mortality: an age- and HIV status-specific retrospective cohort study in Uganda.

Background: Limited studies have explored the relationship between estimated Glomerular Filtration Rate(eGFR) and in-hospital mortality(IHM) in low-income sub-Saharan African countries. This study aimed to explores this association, offering insights into its impact in resource-limited settings.
Methods And Results: We retrospectively included 226 patients(age 45.

Background: Recent studies revealed an association between small kidney volume and progression of kidney dysfunction in particular settings such as kidney transplantation and transcatheter aortic valve implantation. We hypothesized that kidney volume was associated with the incidence of kidney-related adverse outcomes such as worsening renal function (WRF) in patients with acute heart failure (AHF).
Methods: This study was a single-center retrospective cohort study.

Background: Primary hyperoxaluria type 1 (PH1) is an autosomal recessive disorder with dysregulated glyoxylate metabolism in the liver. Oxalate over-production leads to renal stones, progressive kidney damage and renal failure, with potentially life-threatening systemic oxalosis. Nedosiran is a synthetic RNA interference therapy, designed to reduce hepatic lactate dehydrogenase (LDH) to decrease oxalate burden in PH.

Loss of kidney function is a substantial personal and public health burden. Kidney function is typically assessed as estimated glomerular filtration rate (eGFR) based on serum creatinine. UK Biobank provides serum creatinine measurements from study center assessments (SC, n = 425,147 baseline, n = 15,314 with follow-up) and emerging electronic Medical Records (eMR, "GP-clinical") present a promising resource to augment this data longitudinally.

Objective: To identify factors, particularly neonatal acute kidney injury, associated with an increased risk of developing chronic kidney disease (CKD) within the first 10 years of life in children with a history of prematurity and very low birth weight (VLBW).
Methods: This nested case-control study was conducted on VLBW infants (> 500 g and < 1.500 g) born between 2012 and 2022.
