Objective:To assess the prognostic impact of the thoracic aorta and aortic valve calcification volume (TAC, AVC) score based on CT measurementsin patients undergoing transcatheter aortic valve implantation (TAVI).Methods:We retrospectively analyzed 102 patients who underwent TAVI for severe aortic stenosis from March 2018 to April 2022 at Fuwai Central China Cardiovascular Hospital. The patients were stratified into low TAC and AVC group (TAC low, AVC low) and high TAC and AVC group (TAC high, AVC high) based on median TAC and AVC. The independent risk factors affecting the prognosis of TAVI patients were analyzed using univariate and multivariate Cox proportional risk regression, and the independent risk factors affecting the prognosis of TAVI were analyzed by survival curve. Results:A total of 102 patients were included with a median follow-up of 695 (602, 923) days, during which 9 (8.8%) all-cause deaths and 33 (32.4%) composite end-point events occurred. Univariate Cox risk regression analysis found that TAC was a risk factor for all-cause mortality events in TAVI patients ( P=0.039), TAC and AVC were risk factors for composite endpoint events in TAVI patients ( P=0.047, 0.035).TAC was an independent predictor of all-cause mortality after TAVI in multivariate analysis ( HR=8.971, 95% CI 1.121-71.790, P=0.039), and TAC and AVC were independent risk factors for composite endpoint events after TAVI ( HR=2.243, 95% CI 1.099-4.578, P=0.026; HR=2.346, 95% CI 1.146-4.804, P=0.020). Kaplan-Meier survival curves showed that high TAC and AVC scores increased the risk of end-point events ( P<0.05). Conclusion:CT-quantified TAC and AVC volume scores are independent prognostic markers in TAVI patients, with greater calcification burden portending poorer clinical outcomes.

There are many kinds of medical facial protective equipment with different functions. However, due to the lack of recognition of the hazards of facial occupational exposure, an incomplete understanding of the functions and effects of protective equipment and a lack of awareness, the proportion of staff that wear protective equipment in the Department of Stomatology is low. In this paper, the harmful and protective effects of face occupational exposure of dental staff were reviewed. A literature review showed that with the increasing prevalence of infection with AIDS, hepatitis B, hepatitis C and multidrug resistant bacteria in recent years, the occupational infection rate of medical staff in the Department of Stomatology has increased. The noise generated during oral treatment and the light from photosensitive curing lamps and treatment or surgical lasers can also cause occupational damage to hearing and vision. Face protection measures lack comprehensive functioning, and there is a lack of products that can be easily worn, indicating that the functions of face protection products need to be improved and strengthened. To minimize occupational infection and injury, we should not only improve the existing protective equipment but also improve personal protection awareness through advertising and education and comprehensively explore effective measures to improve occupational safety to ultimately achieve safe and high-quality medical services.
