Summary: The updated EAU guidelines provide new information on the diagnosis and treatment of NMIBC for clinical practice. Individual risk assessment is crucial in determining the appropriate treatment for patients with different risk levels. Surgical intervention, including radical cystectomy, may be necessary for cases unresponsive to BCG treatment or with high risk of progression.

Summary: The National Kidney Foundation and the American Society of Nephrology have made recommendations regarding the consideration of race in GFR estimation. They suggest implementing the CKD-EPI creatinine equation without the race variable in all US laboratories and promoting the use of cystatin C for more accurate estimation. They also encourage research on new filtration markers and interventions to eliminate racial disparities. The unified approach should be adopted nationwide.

Summary: Peritoneal dialysis (PD)-associated peritonitis is a serious complication of PD, and its prevention and treatment are crucial for reducing patient morbidity and mortality. The ISPD 2022 updated recommendations provide revised definitions, new peritonitis categories and outcomes, and updated targets for overall peritonitis rate and percentage of patients free of peritonitis. The recommendations also cover management of contamination, antibiotic prophylaxis, PD training, and modifiable peritonitis risk factors. Additionally, there are specific recommendations for antibiotic selection, treatment of peritonitis due to specific microorganisms, and adjunctive therapy.

Summary: The fifth edition of the WHO classification of urogenital tumours has made significant revisions, including the introduction of molecular-driven renal tumour classification and simplification of the morphologic classification of penile squamous cell carcinomas. A new chapter has also been added for tumours of the scrotum. The main nomenclature for testicular tumours remains the same, but there have been changes in some terms.

Discovery of Autoantibodies Targeting Nephrin in Minimal Change Disease Supports a Novel Autoimmune Etiology

Troost, Junbo Chen, Damian Fermin, Jennifer L. Yee, Matthew G. Sampson, Laurence H. H. Beck Jr, Joel M. Henderson, Anna Greka, Helmut G. Rennke, Astrid Weins

Summary: In a subset of patients with minimal change disease, circulating nephrin autoantibodies were detected during active disease but significantly reduced or absent during treatment response. These autoantibodies were correlated with podocyte-associated punctate IgG in renal biopsies. A steroid-dependent patient with childhood minimal change disease developed end stage kidney disease, with high pretransplant circulating nephrin autoantibodies associated with massive post-transplant recurrence of proteinuria.

An introduction to inverse probability of treatment weighting in observational research

Nicholas C. Chesnaye, Vianda S. Stel, Giovanni Tripepi, Friedo W. Dekker, Edouard L. Fu, Carmine Zoccali, Kitty J. Jager

Summary: This article introduces the concept of inverse probability of treatment weighting (IPTW) and its application in adjusting for measured confounding in observational research, using a clinical example in nephrology. IPTW involves calculating the probability of exposure to the risk factor or intervention of interest based on individual characteristics (propensity score), and then calculating weights as the inverse of the propensity score. Application of these weights creates a pseudopopulation with balanced confounders across exposed and unexposed groups in studies, and it can also be applied in longitudinal studies to address informative censoring and time-dependent confounding.

Cellular senescence: the good, the bad and the unknown

Weijun Huang, LaTonya J. Hickson, Alfonso Eirin, James L. Kirkland, Lilach O. Lerman

Summary: Cellular senescence plays important roles in tissue remodeling, but excessive senescence may lead to cancer and age-related diseases. It involves cell-cycle arrest and the release of inflammatory cytokines with autocrine, paracrine, and endocrine activities. Therapeutic interventions targeting cellular senescence have shown potential benefits in extending lifespan and reducing tissue injury.

Mineralocorticoid receptor antagonists in diabetic kidney disease - mechanistic and therapeutic effects

Jonatan Barrera-Chimal, Ixchel Lima-Posada, George L. Bakris, Frederic Jaisser

Summary: Non-steroidal mineralocorticoid receptor antagonists (MRAs) show promising therapeutic effects in the treatment of diabetic kidney disease (DKD), including reducing albuminuria, slowing CKD progression, and lowering the risk of adverse cardiovascular outcomes. Compared with steroidal MRAs, non-steroidal MRAs carry a lower risk, providing potential for their use in the treatment of DKD.

Cisplatin nephrotoxicity: new insights and therapeutic implications

Chengyuan Tang, Man J. Livingston, Robert Safirstein, Zheng Dong

Summary: The authors review the mechanisms of cisplatin-induced kidney injury and discuss the challenges and potential targets for renoprotection. The cellular and molecular mechanisms of cisplatin nephrotoxicity involve DNA damage, mitochondrial pathology, oxidative stress, endoplasmic reticulum stress, and stress responses such as autophagy, cell-cycle arrest, senescence, apoptosis, programmed necrosis, and inflammation. Emerging evidence suggests a contribution of epigenetic changes to cisplatin-induced kidney injury. Potential therapeutic targets have been identified, but their effects on the efficacy of cisplatin chemotherapy need further evaluation.

Summary: Metabolic dysfunction-associated fatty liver disease (MAFLD) is proposed as a replacement term for non-alcoholic fatty liver disease (NAFLD) to emphasize the role of metabolic dysfunction and provide inclusive diagnostic criteria. MAFLD is associated with chronic kidney disease (CKD) and may increase the risk of CKD.

Summary: Belimumab was found to be most effective in improving kidney response in patients with proliferative lupus nephritis and baseline urine protein/creatinine ratio under 3 g/g. However, it did not show improvement in kidney response in patients with lupus nephritis and sub-epithelial deposits or with a baseline protein/creatinine ratio of 3 g/g or more.
