Klotho was overexpressed or knocked down via plasmids and small interfering RNA (siRNA). Cell viability, lactate dehydrogenase release, reactive oxygen species (ROS)/malondialdehyde/glutathione (GSH) levels, and pyroptosis markers were measured. Methylation-specific polymerase chain reaction (PCR) and methylation-sensitive high-resolution melting analyzed Klotho promoter methylation and DNA methyltransferase (DNMT) binding, while quantitative real-time polymerase chain reaction and luciferase assays assessed gene expression and Nrf2 activity. DNA methyltransferase 3a (DNMT3a) and DNMT3b were silenced with specific siRNAs to explore their epigenetic roles.</p><p><strong>Results: </strong>We demonstrate that DOX triggers pyroptosis via caspase-1 activation, gasdermin D N-terminal fragment, and interleukin-1β and interleukin-18 secretion, accompanied by an increase in ROS and depletion of GSH and antioxidant enzymes. Pyroptosis was ROS-dependent, as pretreatment with N-acetyl-L-cysteine restored redox balance and suppressed cell death. Mechanistically, DOX downregulated Klotho expression via promoter cytosine-phosphate-guanine hypermethylation mediated by DNMTs DNMT3a and DNMT3b, with DNMT3b playing a dominant role. Klotho suppression exacerbated pyroptosis, while its overexpression reducing apoptosis-associated speck-like protein containing a CARD speck formation. Furthermore, Klotho activated the Nrf2 pathway, restoring Nrf2 levels and upregulating antioxidant genes heme oxygenase-1 (HO-1) and NAD(P)H quinone oxidoreductase 1 (NQO1).

This study aims to investigate the risk factors of 1-year readmissions in TS patients and the impact of socioeconomic factors, comparing results with matched individuals from the general population and those with MI.</p><p><strong>Methods: </strong>A nationwide cohort study was conducted using national registers. Patients discharged alive from Danish hospitals with an incident TS diagnosis between 2008 and 2018 were identified through the Danish National Patient Registry.
