Daily suicide and meteorological data from 2002 to 2021 were analyzed using a time-stratified case-crossover approach with a distributed lag nonlinear model, adjusted for relative humidity. Province-specific estimates were pooled through a multivariate meta-regression model. The study found a positive, mostly linear association between temperature and suicide risk, with a relative risk (RR) of 1.70 (95% CI: 1.35, 2.15) across the temperature range. Approximately 24.61% of suicides were attributable to temperature, with 12.05% due to hot temperatures above the 66th percentile. The pooled attributable fractions were higher in the 0–64 age group compared to those aged ≥65, while differences between sexes were not statistically significant. This study highlights the significant association between higher ambient temperatures and increased suicide risks in Thailand, emphasizing the need to integrate climate considerations into mental health and suicide prevention policies.

As a substitute for PFOS, sodium p-perfluorous nonenoxybenzenesulfonate (OBS) is extensively utilized in various applications and detected in human blood. However, its potential health risk in AS remain unclear. In this study, we investigated the comparative impacts of PFOS and OBS on endothelial dysfunction and atherogenesis. In the <i>in vivo</i> study, Apolipoprotein E knockout (ApoE<sup>–/–</sup>) mice were exposed to 0.4 or 4 mg/L PFOS/OBS for 12 weeks. We found that dyslipidemia developed more rapidly in the OBS-exposed mice than in the PFOS-exposed mice. PFOS exhibited a higher enrichment capacity in both blood and aortic tissues than OBS. Remarkably, OBS induced a more pronounced inflammatory response and caused a more significant disruption of the endothelial barrier in the aorta of ApoE<sup>–/–</sup> mice compared to PFOS. <i>In vitro</i> experiments showed that OBS, at the same exposure concentrations and durations as PFOS (0.1–20 μmol/L, 48 h), more effectively inhibited cell viability of human umbilical vein endothelial cells (HUVECs), caused higher levels of lactate dehydrogenase (LDH) release, and enhanced cell adhesion between HUVECs and monocytes. Both PFOS and OBS were found to activate the NF-κB signaling pathway and upregulate the expression of inflammatory factors. Notably, the use of OBS, but not PFOS, was shown to disrupt cell junctions and increase endothelial permeability by activating the MAPK/ERK signaling pathway.

Furthermore, proteomic and metabolomic analyses revealed that the regulation of the Lancl2 protein and the mTOR signaling pathway contributed to the milder inflammatory response observed in the DON-OG group.
