Objective: This study investigates the effects of precision health management combined with dual-energy X-ray absorptiometry (DXA) therapy on bone biomarkers in elderly osteoporotic patients., Methods: 236 elderly patients diagnosed with osteoporosis between May 2020 and November 2021 were enrolled from our hospital. Patients were randomly allocated to either the observation group (n = 118), receiving precision health management alongside DXA therapy, or the control group (n = 118), receiving standard treatment. Clinical data were compared between the two groups. Protein levels of bone formation markers (BSAP, OC) and bone resorption markers (CTX, DPD, TRAP) were analyzed using Western blotting. Bone mineral density (BMD) was measured using DXA at baseline, 12 months, and 24 months. Pain levels were assessed using the Visual Analog Scale (VAS) at the same intervals. Osteoporosis knowledge and self-management confidence were evaluated using respective scales before and after intervention., Results: Baseline characteristics did not significantly differ between groups (P > 0.05). The observation group exhibited decreased BSAP and increased OC and OC protein expressions compared to the control group (P < 0.05). CTX, DPD, and TRAP protein levels were significantly lower in the observation group (P < 0.05). Prior to the intervention, there were no significant variations observed in BMD, as well as VAS, knowledge, and self-efficacy scores between the two groups (P > 0.05). However, over the course of 12 and 24 months, the observation group exhibited significant increases in BMD (P < 0.05). VAS scores were notably lower in the observation group during both follow-up assessments (P < 0.05). Furthermore, knowledge scores were higher in the observation group at 12 and 24 months (P < 0.05), while self-efficacy scores showed significant improvement in the observation group at both follow-up intervals (P < 0.05)., Conclusion: Precision health management combined with DXA therapy positively impacts elderly osteoporotic patients by enhancing bone biomarkers, promoting bone growth, and preventing bone loss. This approach leads to increased BMD, reduced fracture risk, improved pain management, and enhanced knowledge and self-management abilities related to osteoporosis., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Objective: This study explores the association of serum 25-hydroxyvitamin D3 (25(OH)D3) levels with carotid artery intima-media thickness (CIMT), and the presence of carotid atherosclerotic plaques in individuals with a history of smoking., Methods: A total of 469 patients suspected of having carotid atherosclerosis, aged 52 to 73 years with an average age of 65.26 ± 4.37 years, were recruited from the author's hospital from January 2023 to October 2023. All patients had a smoking history of nearly 5 years. Based on their serum 25(OH)D3 levels, they were divided into two groups: the normal group (serum level 30-50 ng/mL, n = 300) and the deficiency group (<30 ng/mL, n = 169). General details of the two patient groups were collected. Carotid artery ultrasound was employed to assess pulse wave velocity (PWV), carotid artery compliance coefficient (CC), and CIMT. Blood chemistry analysis measured serum lipid metabolism indicators including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HD-LC). The relationship between CIMT and each variable was analyzed through Pearson correlation, and logistic regression was used to identify risk factors influencing carotid artery plaque development., Results: General patient information between the two groups showed no significant differences (P > 0.05). Patients in the 25(OH)D3 deficiency group exhibited elevated left and right PWV and CC compared to the 25(OH)D3 normal group (P < 0.05). The deficiency group exhibited larger CIMT and plaque area compared to the normal group (P < 0.05). Additionally, the deficiency group demonstrated higher levels of TC, LDL-C, and HD-LC compared to the normal group (P < 0.05). A moderate positive correlation was found between TC, LDL-C, and CIMT (P < 0.05), while a strong positive correlation existed between 25(OH)D3 and CIMT (P < 0.05). In smokers, the formation of carotid artery plaque was associated with factors such as patient age, CIMT, serum LDL-C, and 25(OH)D3 levels (P < 0.05). As age, CIMT, LDL-C levels increased, and 25(OH)D3 levels decreased, the risk of carotid plaques in smokers increased (P < 0.05)., Conclusions: Smokers with lower 25(OH)D3 levels exhibit higher CIMT and more prominent carotid atherosclerotic plaques, indicating increased arterial stiffness and elevated cardiovascular risk. These findings demonstrate crucial implications that insufficient levels of vitamin D may potentially contribute to a higher risk of atherosclerosis among smokers., Competing Interests: Declaration of competing interest The authors declare no competing interests., (Copyright © 2024 Elsevier Inc.
