Mitochondrial dysfunction is a crucial event in acute kidney injury (AKI), leading to a metabolic shift toward glycolysis and increased lactate production. Lactylation, a posttranslational modification derived from lactate, plays a significant role in various cellular processes, yet its implications in AKI remain underexplored. Here, a marked increase in lactate levels and pan-Kla levels are observed in kidney tissue from AKI patients and mice, with pronounced lactylation activity in injured proximal tubular cells identified by single-cell RNA sequencing.

Congenital thrombotic thrombocytopenic purpura (cTTP), which is associated with mutations in the gene for a disintegrin and metalloproteinase with a thrombospondin type 1 motif member 13 (ADAMTS13), is a chronic and lifelong disease. The clinical course is variable. Regularly using ADAMTS13-containing products such as fresh frozen plasma (FFP) for long-term prophylaxis is the most important treatment to prevent thrombotic microangiopathy (TMA) episodes.

Department of Respiratory and Critical Care Medicine, Xiamen Humanity Hospital Fujian Medical University, Xiamen, China.
Objective: Chronic obstructive pulmonary disease (COPD) and chronic kidney disease (CKD) are significant global health issues with a well-established association between the two. This study aims to assess the risk of developing CKD in patients with COPD through systematic review and meta-analysis, and to explore the impact of CKD on the prognosis of COPD patients.
Methods: A total of 23 studies were included in the analysis, comprising 11 studies on the risk of CKD in patients with COPD, 6 studies on the impact of CKD on the short-term all-cause mortality risk of patients with acute exacerbation of COPD (AECOPD), and 6 studies on the impact of CKD on the long-term all-cause mortality risk of COPD patients.
Case Series of Infection-Related Glomerulonephritis in Quebec Indigenous Peoples.

Division of Nephrology, McGill University, Montreal, QC, Canada.
Rationale: Infection-related glomerulonephritis (IRGN) is an immune-mediated glomerulonephritis caused by extra-renal infectious diseases. There has been an important shift in epidemiology in recent years, with a significant proportion of adults affected. The incidence of IRGN is higher amongst Indigenous populations and especially in those with multiple comorbidities.

Leptospirosis, an infection caused by the spirochete Leptospira and commonly attributed to the underdeveloped world, is frequently under-diagnosed in the United States. This report discusses the case of a 79-year-old male with no significant medical history who presented to the ED with recurrent falls. Initial laboratory results demonstrated severe acute kidney injury, hyperbilirubinemia, and thrombocytopenia.
