Global, regional, and national trends in incidence of depression among women, 1990-2019: An analysis of the global burden of disease study.

Depression is a common mental disorder and more women are affected by depression than men. In this study, we aimed to analyze the trends in the incidence of depression among women from 1990 to 2019 and their associations with sociodemographic and universal health coverage indices based on data from the Global Burden of Disease study 2019. It was observed that while the incidence rate of depression among women decreased by an average of 0.35% per year at the global level, the incidence rate increased at the regional level for the high sociodemographic index region by an average of 0.39% per year from 1990 to 2019. And the global downward trend in incidence rate from 1990 to 2019 was contributed by the downward trend from 2000 to 2009. In Spearman correlation analyzes at the level of country/territory, a negative correlation between the estimated annual percentage change in the incidence rate and the universal health coverage index was found (ρ=-0.15).

Quality Assessment and Classification of Codonopsis Radix Based on Fingerprints and Chemometrics.

In China, Codonopsis Radix (CR) is frequently consumed both as food and medicine. Here, a comprehensive strategy based on fingerprinting and chemometric approaches was created to explore the influence of origins, storage time and kneading processing on the quality of CR. Firstly, high-performance liquid chromatography with diode array detection was used to obtain the fingerprints of 35 batches of CR from six different origins and 33 batches of CR from varying storage times or kneading procedures. Secondly, chemometric methods including similarity analysis (SA), principal component analysis (PCA), hierarchical clustering analysis (HCA), and two-way orthogonal partial least square with discriminant analysis (O2PLS-DA) were used to evaluate the differences of chemical components in CR so as to identify its source and reflect its quality. Moreover, 13 and 16 major compounds were identified as marker compounds for the discrimination of CR from different origins, storage time and kneading processing, respectively. Furthermore, the relative content of the marker components and the exact content of Lobetyolin were measured, indicating that the contents of these components vary significantly between various CR samples. Meanwhile, the chemical components of CR were identified using Mass spectrometry. According to the findings of our investigation, the quality of CR from Gansu was the best, followed by Shanxi and then Sichuan. The quality of CR from Chongqing and Guizhou was poor. At the same time, the quality of CR was the best when it was kneaded and stored for 0 years, indicating that the traditional kneading process of CR is of great significance. Conclusively, HPLC fingerprint in conjunction with chemical pattern recognition and component content determination can be employed to differentiate the raw materials of different CR samples. Additionally, it is also a reliable, comprehensive and prospective method for quality control and evaluation of CR.

Global, regional, and national disease burden of autism spectrum disorder among children under 5 years from 1990 to 2019: An analysis for the Global Burden of Disease 2019 Study.

AIM: To estimate the trend in burden of autism spectrum disorder (ASD) at global, regional, and national levels from 1990 to 2019. METHODS: Annual incident cases, incidence rates, prevalent cases, prevalence rates, disability-adjusted life years (DALYs), and DALY rates of ASD among children under 5 years from 1990 to 2019 were collected from the Global Burden of Diseases Study 2019. The percentage of relative changes in cases and the estimated annual percentage changes (EAPCs) of rates were calculated to reflect the temporal trends of ASD burden. Pearson correlation analysis was used to explore the influential factors for EAPC. RESULTS: Globally, the incidence rate, prevalence rate, and DALY rate of ASD among children under 5 years were 91.09 per 100,000, 439.39 per 100,000, and 68.67 per 100,000 in 2019, respectively. From 1990-2019, the incidence rate decreased (EAPC = -0.09, 95% confidence interval [CI] -0.12 to -0.06), whereas the prevalence rate (EAPC=0.08, 95%CI 0.06-0.09) and DALY rate (EAPC=0.08, 95%CI 0.07-0.10) increased. The largest increases in prevalent cases (80.26%) and DALYs (81.24%) were found in low SDI regions, while High-income North America experienced the fastest increase in incidence rate, prevalence rate, and DALY rate. Moreover, the burden of ASD among male children under 5 years was approximately three times that among female children, despite the slight narrowing of gender disparity. The EAPC of incidence rate was positively correlated with SDI and UHCI in 2019 (P < 0.001). CONCLUSION: ASD is a noticeable child neurodevelopmental syndrome. More attention should be given to early screening, diagnosis, and intervention, particularly in resource-limited areas.
