Polycystic ovary syndrome (PCOS) is one of the most complicated chronic inflammatory diseases in women of reproductive age and is one of the primary factors responsible for infertility. There is substantial dispute relating to the pathophysiology of PCOS. Consequently, there is a critical need for further research to identify the factors underlying the pathophysiology of PCOS. ⋯ Finally, real-time PCR and enzyme linked immunosorbent assay demonstrated that the expression levels of DLAT and NUDT16 were significantly reduced in the granulosa cells of PCOS patients. In conclusion, our findings shed fresh light on the roles of immune infiltration, cuproptosis, and m7G alternations in PCOS. We also provide a reliable biomarker for the pathological classification of PCOS patients.

Research on the use of optical coherence tomography (OCT) in acute coronary syndrome (ACS) has increased in recent years. However, a comprehensive analysis of the trends and hotspots in OCT research is currently lacking. The objective of this study was to identify global trends in research on OCT in ACS from a bibliometric perspective and to provide researchers with new research hotspots. ⋯ The journal with the most publications was the International Journal of Cardiology. Plaque erosion, calcified nodules, and intracoronary imaging are the most recent research hotspots and frontiers. Our work summarizes 25 years of OCT research in the ACS, highlighting hotspots, key themes, and emerging frontiers to help guide future research.

To investigate the use of lipid-lowering drugs and abnormal serum lipid levels in patients at risk of sleep apnea syndrome. Three types of Mendelian randomization (MR) analyses were used. First, a 2-sample Mendelian randomization (TSMR) analysis was used to investigate the association between sleep apnea syndrome risk and serum lipid levels. ⋯ Low serum TG levels have a protective effect against sleep apnea syndrome. The DMR results suggested that the use of HMGCR lipid-lowering drugs (such as statins) and PCSK9 inhibitors has a protective effect against sleep apnea syndrome. However, LPL-based lipid-lowering drugs may increase the risk of sleep apnea syndrome.

This study aims to investigate the connection between 25-hydroxyvitamin D (25(OH)D) levels and the prognosis of breast cancer with various estrogen receptor (ER) statuses. The summary statistics of 25(OH)D levels was obtained from a GWAS of 441,291 individuals and the information of breast cancer was collected from the Breast Cancer Association Consortium. We analyzed the causal association between 25(OH)D levels and breast cancer prognosis using a number of approaches, including inverse variance weighting (IVW). ⋯ Sensitivity analysis did not observe the presence of heterogeneity and horizontal pleiotropy. In multivariate MR analysis, after adjusting for total triglycerides, total cholesterol, and body mass index, the correlation between the protective relationship between 25(OH)D levels and the prognosis for ER- breast cancer remained and became increasingly significant (OR = 0.51, 95% CI = 0.31-0.83, P = .007). This study demonstrated a protective relationship between 25(OH)D levels and the prognosis of ER- breast cancer, but there was no connection between 25(OH)D levels and the prognosis of ER+ breast cancer.

Genetic factors play a significant role in the development of congenital heart disease (CHD). Many studies on the genetics of CHD have been published worldwide; however, no research has assessed and mapped the global research landscape of these studies. This bibliometric and visualized study aimed to delineate research hotspots and trends in the field of CHD genetics. ⋯ To the best of our knowledge, this is the first bibliometric analysis of CHD genetics studies. Tetralogy of Fallot, ventricular septal defect, and atrial septal defect are global research topics. The interactions between environmental and genetic factors in the pathogenesis of CHD, genetic etiology of CHD-associated pulmonary arterial hypertension, and molecular genetics of CHD via high-throughput genomic technology are possible areas of future research on the genetics of CHD.
