Circulating bone marrow-derived endothelial progenitor cells (EPCs) facilitate vascular repair in several organs including the kidney but are progressively diminished in end-stage kidney disease (ESKD) patients, which correlates with cardiovascular outcomes and related mortality. We thus determined if enhancing the tissue-reparative effects of human bone marrow-derived mesenchymal stromal cells (BM-MSCs) with the vasculogenic effects of recombinant human relaxin (RLX) could promote EPC proliferation and function. CD34 EPCs were isolated from the blood of healthy and ESKD patients, cultured until late EPCs had formed, then stimulated with BM-MSC-derived condition media (CM; 25%), RLX (1 or 10 ng/mL), or both treatments combined. Whilst RLX alone stimulated EPC proliferation, capillary tube formation and wound healing in vitro, these measures were more rapidly and markedly enhanced by the combined effects of BM-MSC-derived CM and RLX in EPCs derived from both healthy and ESKD patients. These findings have important clinical implications, having identified a novel combination therapy that can restore and enhance EPC number and function in ESKD patients.

Primary hyperoxaluria type 1 (PH1) is a rare autosomal recessive disorder caused by a deficiency of the hepatic peroxisomal enzyme alanine-glyoxylate aminotransferase (AGT), which catalyses the conversion of glyoxylate to glycine, resulting in increased oxalate production. The clinical consequences of the progressive build up of oxalates include nephrocalcinosis, nephrolithiasis, chronic kidney disease and ultimately renal failure with extra-renal involvement. The diagnosis of PH1 is challenging due to the non-specific nature of its symptoms and the need for costly genetic testing.

Background: Dialysis in neonates with ESKD is often associated with multiple comorbidities and the need for more intensified dialysis regimens. With recent advances in prenatal interventions and infant specific KRT, survival of neonates with ESKD has improved over the last decade. Little is known however about the impact on the health care system of improved survival in this population.

Background: End-stage kidney disease (ESKD) significantly impacts global public health, driven by an ageing population and increased chronic diseases. Over half of patients with ESKD are now over 65 years old, often with multiple comorbidities, complicating management and prognosis. The socioeconomic impact is considerable, and patients with ESKD face higher cancer risks.

The rate of end-stage kidney disease (ESKD) is steadily rising in the United States, and older adults (ie, 65 years and older) represent the fastest-growing segment in need of hemodialysis. This demographic shift presents unique challenges due to age-related comorbidities, frailty, and increased procedural risks. Despite these challenges, there is limited guidance for risk stratification and management of renal replacement therapy in older patients with ESKD.

Obstructive sleep apnea (OSA) is an extremely common but underdiagnosed problem in adults receiving dialysis therapy. Patients with end-stage kidney disease (ESKD) on hemodialysis or peritoneal dialysis have a higher prevalence of OSA compared to the general population (Nicholl et al., 2013; Kimmel et al.
