Despite widespread coronavirus disease 2019 (COVID-19) vaccine use, research on the association between vaccines and cerebrovascular venous sinus thrombosis (CVST) in diverse populations is limited. This study aimed to address this gap. Data from the World Health Organization pharmacovigilance database (1968–2024; total reports = 8,909,484) were used.Reporting odds ratios (RORs) and information components (ICs) were calculated to assess the association between each drug and CVST. In total, 851 cases were identified as vaccineassociated CVST, of which 527 (61.93%) occurred in female patients. Only Ad5-vectored COVID-19 vaccines had the highest ROR and IC value with CVST (ROR, 4.78; 95% confidence interval, 4.34–5.28; IC, 2.15). The risk of CVST increased with age, with the 45–64-years age group having an IC of 1.35, while the 65 years and older group had a higher IC of 2.08.The findings highlight the need for clinicians to recognize the potential risks of CVST and prioritize rigorous monitoring and research to ensure patient safety.

Macrophages play a central role in cardiovascular diseases, like atherosclerosis, by accumulating in vessel walls and inducing sustained local inflammation marked by the release of chemokines, cytokines, and matrix-degrading enzymes. Recent studies indicate that 6'-sialyllactose (6'-SL) may mitigate inflammation by modulating the immune system. Here, we examined the impact of 6'-SL on lipopolysaccharide (LPS)-induced acute inflammation using RAW 264.7 cells and a mouse model.In vivo, ICR mice received pretreatment with 100 mg/kg 6'-SL for 2 h, followed by intraperitoneal LPS injection (10 mg/kg) for 6 h. In vitro, RAW 264.7 cells were preincubated with 6'-SL before LPS stimulation. Mechanistic insights were gained though Western blotting, qRT-PCR, and immunofluorescence analysis, while reactive oxygen species (ROS) production was assessed via DHE assay. 6'-SL effectively attenuated LPS-induced p38 MAPK and Akt phosphorylation, as well as p65 nuclear translocation. Additionally, 6'-SL inhibited LPS-induced expression of tissue damage marker MMP9, IL-1β, and MCP-1 by modulating NF-κB activation. It also reduced ROS levels, mediated by p38 MAPK and Akt pathways. Moreover, 6'-SL restored LPS-suppressed Nrf2 and HO-1 akin to specific inhibitors SB203580 and LY294002. Consistent with in vitro results, 6'-SL decreased oxidative stress, MMP9, and MCP-1 expression in mouse endothelium following LPS-induced macrophage activation. In summary, our findings suggest that 6'-SL holds promise in mitigating atherosclerosis by dampening LPS-induced acute macrophage inflammation.

Purpose: The estimated glomerular filtration rate (eGFR) at 6 months after donation (eGFR 6m) is strongly associated with the risk of end-stage renal disease in living kidney donors. This study aimed to investigate the incidence of eGFR 6m <60 mL/min/1.73 m 2 eGFR 6m <60) and identify the risk factors that can predict the occurrence of eGFR 6m <60 in living kidney donors. Materials and Methods: Living kidney donors who underwent nephrectomy at Severance Hospital between January 2009 and December 2019 were identified. We excluded 94 of 1233 donors whose creatinine values at 6 months after donation were missing. The risk factors for eGFR 6m <60 were assessed using multivariate regression analysis. The optimal cutoff points for candidate risk factors for predicting eGFR 6m <60 occurrence were determined using the Youden index. Results: The eGFR 6m <60 occurred in 17.3% of the participants. Older age (≥44 years), history of hypertension, lower preoperative eGFR (<101 mL/min/1.73 m 2 ), and degree of increase in creatinine levels on postoperative day 2 compared to those before surgery (ΔCr2_pre) (≥0.39 mg/dL) increased the risk of eGFR 6m <60. The addition of ΔCr2_pre to preoperative eGFR yielded a higher predictive accuracy for predicting eGFR 6m <60 than that with preoperative eGFR alone {area under the receiver operating characteristic curve=0.886 [95% confidence interval (CI), 0.863–0.908] vs. 0.862 (95% CI, 0.838–0.887), p<0.001}. Conclusion The incidence of eGFR 6m <60 was 17.3%. Older age, lower preoperative eGFR, history of hypertension, and greater ΔCr2_pre were associated with the occurrence of eGFR 6m <60 after living donor nephrectomy. The combination of preoperative eGFR and ΔCr2_pre showed the highest predictive power for eGFR 6m <60.
