Objective:To investigate the incidence of osteoporosis (OP) in maintenance hemodialysis (MHD) patients at the blood purification center in Gaochun district, and analyze its influencing factors.Methods:A retrospective study was conducted on 3 622 patients who received regular MHD treatment at Nanjing Gaochun People′s Hospital and Nanjing Gaochun Traditional Chinese Medicine Hospital from January 2019 to December 2023. The demographic characteristics, comorbidities, and clinical data such as blood calcium and creatinine of patients were collected. The ultivariate Logistic regression model was applied to analyze the influencing factors of OP in MHD patients.Results:The survey revealed that 33.63% of MHD patients had decreased bone mass, and 37.24% of MHD patients experienced osteoporosis. According to the occurrence of OP, 3 622 patients were separated into the OP group (1 349 cases) and the non-OP group (2 273 cases). Univariate analysis showed that compared with the non-OP group, the albumin (ALB) level in the OP group was lower: (38.95 ± 5.17) g/L vs. (40.32 ± 5.84) g/L, there was statistical difference( P<0.05). Compared with the non-OP group, the levels of immunoreactive parathyroid hormone (iPTH) and alkaline phosphatase (ALP) in the OP group were higher: (262.29 ± 36.76) ng/L vs. (249.55 ± 32.73) ng/L, (114.74 ± 18.01) U/L vs. (109.63 ± 17.25) U/L, the proportion of patients aged≥60 years old, female and dialysis duration≥5 years was higher: 61.75%(833/1 349) vs. 47.87%(1 088/2 273), 66.35%(895/1 349) vs. 54.86%(1 247/2 273), 52.34%(706/1 349) vs. 34.36%(781/2 273), there were statistical differences( P<0.05). Multivariate Logistic regression revealed ALB ( OR = 0.724, 95% CI 0.568 - 0.920), iPTH ( OR = 1.374, 95% CI 1.095 - 1.725), ALP ( OR = 1.325, 95% CI 1.070 - 1.641), age ( OR = 2.753, 95% CI 1.664 - 4.556), gender ( OR = 2.993, 95% CI 1.611 - 5.560), and dialysis time ( OR = 4.216, 95% CI 2.365 - 7.516) were all influencing factors for the occurrence of OP in MHD patients ( P<0.05). Conclusions:The incidence of OP in MHD patients in Gaochun district is high, and its occurrence is closely related to ALB, iPTH, ALP, age, gender and dialysis time. Clinical attention should be focused on this.

Objective:To assess the effectiveness of combining color Doppler ultrasound (CDU) with shear wave elastography (SWE) in forecasting the likelihood of breast cancer (BC) recurrence.Methods:From Jan. 2022 to Jan. 2024, we gathered data on 92 BC patients admitted to Shanxi Maternal and Child Health Hospital and Shanxi Cancer Hospital, focusing on their lesion characteristics. Each patient underwent CDU and SWE examinations pre-surgery and was monitored for a year. Based on BC recurrence, patients were categorized into recurrence and non-recurrence groups. We compared CDU imaging and hemodynamic features of BC between these groups and evaluated SWE elastic modulus values. To assess the agreement between CDU, SWE, and their combined use in predicting BC recurrence and pathological diagnosis, we employed the Kappa test. Additionally, we plotted ROC curves to analyze the predictive power of CDU, SWE, and their combination in assessing BC recurrence risk. Results:Among the 92 BC patients studied, 38 experienced recurrence, while 54 did not. CDU examination revealed that the non-recurrence group exhibited significantly larger tumor maximum diameter, higher peak systolic velocity (PSV), a higher proportion of aspect ratio ≥ 1, irregular margins, calcification, and increased vascular abundance, compared to the recurrence group ( t/ χ2=17.188, 18.491, 6.099, 15.374, 14.526, 19.318, P<0.05). Additionally, the vascular resistance index (RI) was lower in the non-recurrence group ( t=-26.429, P<0.05). SWE results indicated that the recurrence group had higher average (E mean), maximum (E max), and minimum (E min) elastic moduli compared to the non-recurrence group ( t=14.39, 12.34, 8.29, P<0.05). CDU and SWE predictions showed substantial agreement with pathological results, with Kappa values of 0.66 and 0.69, respectively ( P<0.05). The combination of CDU and SWE predictions demonstrated excellent concordance with pathological outcomes ( Kappa=0.91, P<0.05). In terms of predicting BC recurrence risk, CDU and SWE had accuracies of 83.70% and 84.21%, respectively. The ROC curve analysis showed AUC values of 0.830 for CDU, 0.847 for SWE, and 0.955 for their combination. Sensitivity was 0.870 for CDU, 0.852 for SWE, and 0.963 for the combination. Specificity was 0.789 for CDU, 0.842 for SWE, and 0.947 for the combination. Positive predictive values were 78.95% for CDU, 84.21% for SWE, and 94.74% for the combination, while negative predictive values were 87.04% for CDU, 85.19% for SWE, and 96.30% for the combination. The AUC for CDU in predicting post-operative BC recurrence risk was not significantly different from SWE ( χ2=0.04, P>0.05), but the combined prediction AUC was significantly higher than individual predictions ( χ2=8.00, 7.04, P<0.05) . Conclusion:The predictive value of CDU and SWE combined examination for the recurrence risk of BC is better than that of single examination, and it is suggested that the combined examination method should be popularized in clinic.
