Summary: IF/TA density (the number of IF/TA foci per area of cortex) predicts progressive CKD and noncancer mortality after nephrectomy, independent of the percentage of IF/TA. A higher density of IF/TA foci suggests more scattered damage to the nephrons and worse kidney prognosis at the same percentage of IF/TA.

Summary: In patients with cirrhosis, formulas for estimating renal function, whether specific to this population or classic equations, have not been proven to be reliable. The study found poor agreement between estimated and measured glomerular filtration rate in cirrhotic patients, indicating caution should be exercised when using eGFR in this population.

Summary: In this study, 114 IFTA diagnostic models were developed using 13 machine learning algorithms based on necroptosis-related genes. The top model was tested using independent data sets, confirming the significant role of necroptosis in the development of IFTA.

Summary: Radiotherapy is commonly used in breast cancer treatment, but it can lead to fibrosis and atrophy of the pectoralis major muscle. This study used ultrasound shear wave elastography and B-mode imaging to assess muscle stiffness and thickness of the pectoralis major muscle after radiotherapy. Changes in muscle stiffness and thickness were detected within the first twelve months after radiotherapy, suggesting that these parameters could be used to identify patients who would benefit from post-radiotherapy physical therapy. Further studies with larger sample sizes and patients receiving nodal radiation are needed to confirm these findings.

Summary: This study examines the awareness and adoption of new equations for estimated glomerular filtration rate (eGFR) in clinical laboratories that participated in the first general chemistry proficiency testing survey in 2022. The new equations, proposed by the Chronic Kidney Disease Epidemiology Collaboration, eliminate race-adjustment factors and include equations based on creatinine alone or a combination of creatinine and cystatin C.

Summary: This study used data from the Alzheimer's Disease Neuroimaging Initiative (ADNI) to investigate the association between estimated glomerular filtration rate (eGFR) and brain volumes. The results indicate that mild to moderate kidney dysfunction is not associated with brain atrophy.

Summary: Multiple motile cilia with a central microtubular pair were found in kidney biopsies of patients with kidney diseases, and these cells were associated with tubular injury and interstitial fibrosis. This suggests the ability of proximal tubular cells to transdifferentiate into multiciliated cells.

Summary: Evaluation of hepatic fibrosis is important for preventing liver-related morbidity and mortality. This study compared the diagnostic performances of two ultrasound shear wave elastography techniques, 2D-SWE and p-SWE, for evaluating liver fibrosis. The results showed that 2D-SWE had higher reliability in measuring liver stiffness values and higher accuracy for diagnosing significant fibrosis and cirrhosis.

Summary: The study demonstrates that ML algorithms can effectively replicate the assessment of interstitial fibrosis and glomerulosclerosis performed by renal pathologists, with results highly consistent with pathologists' analysis. Therefore, computational methods may provide a standardized approach to evaluate the extent of chronic kidney injury in situations where renal pathologist time is limited or unavailable.

Summary: The study suggests that NLR is positively correlated with renal tubular atrophy/interstitial fibrosis in IgAN patients, and can be a potential predictor for prognosis.

Summary: This study compares the performance of different equations for glomerular filtration rate (GFR) evaluation in cancer patients. The results show that the Cockcroft-Gault equation is the least accurate, while the CKD-EPI equation and eGFRcr-cys equation perform better. Therefore, it is recommended to adopt guideline-recommended methods for GFR evaluation in oncology practice and clinical trials.

Summary: This study evaluates the utility of 2-D shear wave elastography (SWE) in assessing liver fibrosis in patients with chronic liver disease. It compared the performance of 2-D SWE with point shear wave elastography (pSWE), using liver histological staging as the reference standard. The results showed that 2-D SWE provides feasible and accurate assessment of liver fibrosis, comparable to that of pSWE.

Summary: This study found that approximately two-thirds of patients with hypertension or diabetes were undetected for albuminuria, leading to an increased risk of chronic kidney disease (CKD) progression and cardiovascular morbidity. Therefore, improving the accuracy and utilization of albuminuria testing can help reduce the risk of CKD progression and cardiovascular complications.

Summary: This study validates the predictive value of the revised Oxford classification on renal survival and identifies worse renal outcomes in patients with severe tubulointerstitial fibrosis and atrophy. Patients with extracapillary lesions >25% and IFTA >50% have a poorer renal prognosis due to more severe kidney injury. These findings contribute to patient stratification in IgA nephropathy for therapeutic, epidemiological, and basic research purposes.

Summary: This study aimed to assess the effect of tubulointerstitial inflammation (TII) and interstitial fibrosis and tubular atrophy (IFTA) on kidney survival in lupus nephritis (LN). The results showed that patients with moderate-to-severe IFTA had worse kidney survival compared to those with none or mild IFTA. Additionally, worse kidney survival was found among patients with fibrous crescents and IV LN compared to those without fibrous crescents and IV LN, respectively.
