RESUMEN
This study investigated subtrochanteric femoral metastases using a retrospective approach by analyzing data from 109 patients with bone metastases (2015-2019). Surgical methods were compared: curettage with intramedullary nail and bone cement versus prosthetic reconstruction. Post-surgical assessments included joint function, bone metastasis-related serum markers, and complications. Univariate and multivariate logistic regression analysis was used to screen independent risk factors affecting patients' prognosis. R language was used to construct a nomogram model for predicting patients' 1- and 2-year survival, which was validated through ROC curves and the calibration chart. Patients treated with curettage showed superior postoperative outcomes, exhibiting significantly higher Karnofsky Performance Status (KPS) scores (80.00 vs. 70.00, P < 0.001) and Musculoskeletal Tumor Society Scores (MSTS) (23.86 ± 2.57 vs. 21.67 ± 3.24, P < 0.001). Both methods demonstrated comparable efficacy in pain control (VAS: 3.00 vs. 3.00, P > 0.05) and bone metabolism impact (ALP: 85.93 ± 14.44 vs. 83.19 ± 21.19; CTX-I: 3.03 ± 1.56 vs. 3.15 ± 1.75; PINP: 10.30 ± 4.41 vs. 11.57 ± 3.90; all P > 0.05). Cox regression identified treatment regimen, age, diabetes, and pre-treatment KPS score as significant survival factors (all P < 0.05). The nomogram model demonstrated high accuracy in predicting one-year and two-year survival (AUC: 0.821 and 0.790, respectively). In conclusion, curettage with intramedullary nail and bone cement enhances postoperative functional recovery and quality of life for subtrochanteric femoral metastases patients, representing a promising treatment method.
RESUMEN
Uric acid (UA) and HDL-cholesterol (HDL-C) level are closely associated to the cardiovascular disease (CVD) morbidity. The UA/HDL-C ratio (UHR), a new parameter combination of serum UA and HDL-C, attracts attention for its association with metabolic and inflammatory conditions. There may exists the association between UHR and arterial stiffness. This study aims to explore the association between the UHR and brachial-ankle PWV (baPWV) and to determine whether or not UHR has effect on arterial stiffness. The present study included a total of 912 Japanese (592 men and 320 women), aged from 24 to 84, received a health medical checkup programme with an automatic waveform analyzer to measure baPWV and various standardized questionnaires in a medical center of Japan. Non-linear regression and threshold effect analysis were conducted to explore the association between UHR and baPWV. It was found that UHR was positively correlated with baPWV after adjusting for multiple confounders. A non-linear relationship (with a inflection point was 14.25) was found between UHR and baPWV. Subgroup analyses showed that the significant association between UHR and baPWV only existed in females group, no fatty liver group and normal BMI groups. This study revealed the nonlinear relationship between UHR and baPWV. A significant correlation between UHR and baPWV existed in females but not in males. Fatty liver status, BMI, and menopausal status may affect the above association.
