The genetic correlation and causal association between key factors that influence vascular calcification and cardiovascular disease incidence

Background: Serum calcium (Ca), vitamin D (VD), and vitamin K (VK) levels are key determinants of vascular calcification, which itself impacts cardiovascular disease (CVD) risk. The specific relationships between the levels of these different compounds and particular forms of CVD, however, remain to be fully defined. Objective: This study was designed to explore the associations between these serum levels and CVDs with the goal of identifying natural interventions capable of controlling vascular calcification and thereby protecting against CVD pathogenesis, extending the healthy lifespan of at-risk individuals.Methods: Linkage disequilibrium score (LDSC) regression and a two-sample Mendelian randomization (MR) framework were leveraged to systematically examine the causal interplay between these serum levels and nine forms of CVD, as well as longevity through the use of large publically accessible Genome-Wide Association Studies (GWAS) datasets. The optimal concentrations of serum Ca and VD to lower CVD risk were examined through a restrictive cubic spline (RCS) approach.Results: After Bonferroni correction, the positive genetic correlations were observed between serum Ca levels and myocardial infarction (MI) (p = 1.356E–04), as well as coronary artery disease (CAD) (p = 3.601E–04). Negative genetic correlations were detected between levels of VD and CAD (p = 0.035), while elevated VK1 concentrations were causally associated with heart failure (HF) [odds ratios (OR) per 1-standard deviation (SD) increase: 1.044], large artery stroke (LAS) (OR per 1-SD increase: 1.172), and all stroke (AS) (OR per 1-SD increase: 1.041). Higher serum Ca concentrations (OR per 1-SD increase: 0.865) and VD levels (OR per 1-SD increase: 0.777) were causally associated with reduced odds of longevity. These findings remained consistent in sensitivity analyses, and serum Ca and VD concentrations of 2.376 mmol/L and 46.8 nmol/L, respectively, were associated with a lower CVD risk (p &lt; 0.001). Conclusion: Our findings support a genetic correlation between serum Ca and VD and CVD risk, and a causal relationship between VK1 levels and CVD risk. The optimal serum Ca (2.376 mmol/L) and VD levels (46.8 nmol/L) can reduce cardiovascular risk.</p

A rare complication: The rupture of sinus of valsalva during the percutaneous coronary intervention

Rupture of the sinus of Valsalva is an extremely rare complication of percutaneous coronary intervention. It could lead to lethal sequelae if not coded properly. We experienced a rupture of sinus of Valsalva during the percutaneous coronary intervention which led to pericardial tamponade, causing hemodynamic instability. Surgery was performed immediately, and the patient was discharged without symptoms. Manipulation of the guiding catheter should be performed with great caution during the whole procedure, especially in patients with hypertension, atherosclerosis, or other diseases

Research hotspots and trends of oral health in older adults from 2013 to 2023: A bibliometric and visual analysis

Background: Oral health problems seriously affect the quality of life of older adults. It is of great significance to investigate the statuses of oral health in older adults. The study aimed to analyze the current status, hotspots and frontiers of global oral health research in older adults through bibliometrics to provide references and guidance for future research in this field. Methods: Literature on oral health in older adults from 2013 to 2023 was retrieved from the Web of Science Core Collection (WoSCC) database. CiteSpace 6.2.R4 was used for bibliometric and visual analysis, including journal and co-cited journal, country/region, institution, author, co-cited references, and keyword analysis. Results: A total of 1430 publications related to oral health in older adults were included. The number of publications has gradually increased over the past decade. The most widely published and cited journal was Gerodontology. The most prominent contribution came from the United States of America, and the University of London and Hirohiko Hirano were the most prolific institution and author, respectively. The current research hotspots were summarized as oral hygiene interventions, oral health-related quality of life and oral health issues in older adults. Cohort studies of oral health, the relationship between oral health and frailty, and the correlation between oral health and nutritional status may be emerging research trends. Conclusions: This study systematically analyzed the hotspots and frontiers of oral health in older adults and called for increased collaboration among countries, institutions, and authors. In addition, oral hygiene interventions for older adults, oral health-related quality of life, oral health issues, cohort studies of oral health, and the relationship between oral health and frailty or nutritional status may be the focus of future research

Ensemble machine learning approach for screening of coronary heart disease based on echocardiography and risk factors

Abstract Background Extensive clinical evidence suggests that a preventive screening of coronary heart disease (CHD) at an earlier stage can greatly reduce the mortality rate. We use 64 two-dimensional speckle tracking echocardiography (2D-STE) features and seven clinical features to predict whether one has CHD. Methods We develop a machine learning approach that integrates a number of popular classification methods together by model stacking, and generalize the traditional stacking method to a two-step stacking method to improve the diagnostic performance. Results By borrowing strengths from multiple classification models through the proposed method, we improve the CHD classification accuracy from around 70–87.7% on the testing set. The sensitivity of the proposed method is 0.903 and the specificity is 0.843, with an AUC of 0.904, which is significantly higher than those of the individual classification models. Conclusion Our work lays a foundation for the deployment of speckle tracking echocardiography-based screening tools for coronary heart disease

Overpressure reservoirs of the Huangliu Formation of the Dongfang area, Yinggehai Basin, South China Sea

The relationship between reservoir property and such factors as sedimentary microfacies, clastic component, grain size, and special diagenetic environment of high temperature and overpressure were comprehensively analyzed to study reservoir characteristics and influencing factors in the first member of upper-Miocene Huangliu Formation of the DF13-1 structure in the Dongfang area, Central Diapir Zone of the Yinggehai Basin. The dominant reservoirs in the first member of the Huangliu Formation in the Dongfang area are composed of very fine to fine lithic quartz sandstones that are deposited in submarine fans sourced from the Kuntom Uplift. The reservoirs are characterized by large thickness, broad distribution and good qualities. High-temperature thermal fluids activities and overpressure are two major diagenetic factors contributing to the good properties in the reservoirs. Thermal fluids activities of high tempreture accelerated the organic matter thermal evolution and clay mineral transformation, and in this process organic acids and CO2 were generated which dissolved the reservoirs and thus resulted in a secondary pore zone. Overpressure broadened oil generation window, increased corrosion time and strength, making secondary pores developed in deeper formations. Moreover, the overpressure was beneficial to preserve pores. The reservoir economic basement depths of siltstone, very fine sandstone and fine sandstone are about 3 100 m, 3 900 m and 5 000 m respectively. The fine sandstone and very fine sandstone in the first member of the Huangliu Formation could form high-quality gas reservoirs in present depth of 2 600–3 500 m.
