A multicenter study was undertaken in Japan to evaluate the correlation between the percentage of renal uptake of 99mTc-mercaptoacetyltriglycine (99mTc-MAG3) estimated by the count-based gamma camera method and the blood clearance of 99mTc-MAG3. Twenty four centers were enrolled and 172 cases were finally analyzed in this study. The renal clearance of 99mTc-MAG3 (TER) was obtained by using a single blood sample taken at 44 min after injection. Comparison of TER and renal uptake provided a coefficient of correlation of 0.874; suggesting that sufficiently accurate quantification of renal function could be obtained from the renal uptake estimate by the gamma camera method. This study also showed that the comparison of renal function might be feasible among patients under the same protocols, although precise and careful consideration is required in each center.

Objective: Elevated systolic blood pressure and increased pulse pressure are closely associated with renal damage; however, the exact mechanism remains unclear. Therefore, we investigated the effects of increased pulse pressure on tubulointerstitial fibrosis and renal damage in elderly rats with isolated systolic hypertension (ISH). Additionally, the role of renal tubular epithelial-mesenchymal transition (EMT) and its upstream signalling pathways were elucidated.

Case Report: We report the consequences of inappropriate prescriptions in a 99-year-old woman. She had a clinical history of vascular dementia, diabetes, hypothyroidism, heart failure, osteoarthritis, chronic renal failure, and hypoacusia, and was admitted to our attention for asthenia and loss of appetite.

Cardiovascular-kidney-metabolic (CKM) syndrome is the association between obesity, diabetes, CKD (chronic kidney disease), and cardiovascular disease. GDF-15 mainly acts through the GFRAL (Glial cell line-derived neurotrophic factor Family Receptor Alpha-Like) receptor. GDF-15 and GDFRAL complex act mainly through RET co-receptors, further activating Ras and phosphatidylinositol-3-kinase (PI3K)/Akt pathways through downstream signaling.

Background: Hyperuricemia (HUA) is a condition characterized by excessive uric acid production and/or inadequate uric acid excretion due to abnormal purine metabolism in the human body. Uric acid deposits resulting from HUA can lead to complications such as renal damage. Currently, drugs used to treat HUA lack specificity and often come with specific toxic side effects.

Various tubular diseases in patients with multiple myeloma (MM) are caused by monoclonal immunoglobulin light chains (LCs). However, the physicochemical characteristics of the disease-causing LCs contributing to the onset of MM-associated tubular diseases remain unclear. We herein report a rare case of MM-associated combined tubulopathies: non-crystalline light chain proximal tubulopathy (LCPT) and crystalline light chain cast nephropathy (LCCN).
