Progestogens commonly used in the clinic include levonorgestrel, etonogestrel, medroxyprogesterone, hydroxyprogesterone, progesterone, desogestrel, and megestrol. Progestogens are widely used for contraception and the treatment of endometriosis, threatened abortion and other diseases. However, the correlation between progestogen use and depression is not clear. Therefore, this study used data from the FDA Adverse Event Reporting System (FAERS) database to assess the relationship between progestogen levels and depression. In this study, all data from the first quarter of 2004 to the third quarter of 2024 were extracted and imported into SAS 9.4 software for data cleaning and analysis. The reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian Confidence Propagation Neural Network (BCPNN) and Multi-item Gamma Poisson Shrinker (MGPS) were used for Bayesian analysis and disproportionation analysis. Levonorgestrel, medroxyprogesterone, etonogestrel and desogestrel presented positive signals for depression, and medroxyprogesterone also presented positive signals for major depression. Although none of the progestogens presented positive signals for suicide or self-harm, medroxyprogesterone presented a positive signal for suicidal ideation. Conclusion Analysis of data from the FAERS database revealed that levonorgestrel, medroxyprogesterone, etonogestrel, and desogestrel were correlated with depression. These findings provide real-world evidence of the potential risk of progestogen-related depression.

1. IntroductionWith the support of the Chinese government policies, new energy devices such as wind power and photovoltaic systems are being extensively integrated into the power grid. It is projected that by 2025, the G province of China will add approximately 18 million kilowatts of wind power and 10 million kilowatts of photovoltaic power. These additions of new energy devices provide green and renewable energy sources.

Digital trade, as one of the vanguards of the global technological revolution and industrial transformation, empowers low-carbon economic cooperation on a global scale. This study based on panel data from 2007 to 2021 of 46 countries with varied development levels, constructed a multi-dimensional indicator system from six aspects: trade potential, digital infrastructure, digital innovation, digital skills and security, scale of digital trade, and digital trade environment, aim to measure the development level of digital trade and explore its impact on carbon emissions, followed by a heterogeneity analysis. The research results indicate that there are significant differences in the development levels of digital trade among countries with different economic strengths. Countries with stronger economic power and larger trade scales have a higher level of digital trade development, while less developed regions lag in digital trade. As the level of digital trade development increases, the impact of digital trade on carbon emissions will also change. Overall, digital trade exhibits a pronounced low-carbon effect, while its impact varies among countries with different development levels.
