Bisphenol A (BPA) is a widespread environmental pollutant linked to detrimental effects on human health and reduced life expectancy following chronic exposure. This prospective cohort study aimed to examine the association between BPA exposure and mortality in American adults and to explore the potential mitigating effects of dietary quality on BPA-related mortality. This study utilized data from 8761 American adults in the 2003-2016 National Health and Nutrition Examination Survey (NHANES). Urinary BPA levels were employed to assess BPA exposure, and dietary quality was evaluated using the Healthy Eating Index-2015 (HEI-2015). All-cause, cardiovascular disease (CVD), and cancer mortality statuses were determined until December 31, 2019, resulting in a cumulative follow-up of 80,564 person-years. The results showed that the highest tertile of urinary BPA levels corresponded to a 36% increase in all-cause mortality and a 62% increase in CVD mortality compared to the lowest tertile. In contrast, the highest tertile of HEI-2015 scores was associated with a 29% reduction in all-cause mortality relative to the lowest tertile. Although no significant interaction was found between HEI-2015 scores and urinary BPA levels concerning mortality, the association between HEI-2015 scores and both all-cause and CVD mortality was statistically significant at low urinary BPA levels. Continuous monitoring of BPA exposure is crucial for evaluating its long-term adverse health effects. Improving dietary quality can lower all-cause mortality and decrease the risk of all-cause and CVD mortality at low BPA exposure levels. However, due to the limited protective effect of dietary quality against BPA exposure, minimizing BPA exposure remains a vital goal., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

Long non-coding RNA steroid receptor RNA activator (lncRNA-SRA) has been proven to regulate vascular smooth muscle cell (VSMC) proliferation, indicating its possible involvement in cardiovascular disease. Diabetes is a major cause of cardiovascular disease. The aim of the present study was to investigate the involvement of lncRNA-SRA in type II diabetic cardiovascular disease. The plasma levels of lncRNA-SRA were identified to be significantly lower in patients with type II diabetic cardiovascular disease compared with those in type II diabetic patients without any obvious complications and in healthy controls. A 5-year follow-up study revealed that low vs. high expression levels of lncRNA-SRA were associated with an increased incidence of cardiovascular disease in type II diabetic patients. High-glucose treatment did not significantly affect the expression of lncRNA-SRA in human VSMCs in vitro. However, ectopic overexpression of lncRNA-SRA increased the viability of human VSMCs in a high-glucose environment. It was concluded that downregulation of lncRNA-SRA may participate in the development of cardiovascular disease in type II diabetic patients. [ABSTRACT FROM AUTHOR]
