Objective: To evaluate the clinical efficacy of antibiotic bone cement plus lateral bone repositioning for severe diabetic foot and its impact on wound healing rate. Methods: Sixty patients with hemodialysis anemia admitted to the endocrinology department of our hospital from July 2020 to July 2021 were included and randomly assigned to receive antibiotic bone cement plus lateral bone repositioning (observation group) or vacuum sealing drainage (VSD) (control group). Outcome measures included skin temperature of the affected limb, ankle-brachial index, sensory threshold, foot wound healing, dorsalis pedis artery hemodynamics, lower limb function and clinical efficacy. Results: Antibiotic bone cement plus lateral bone repositioning resulted in significantly higher treatment efficiency and transcutaneous partial pressure of oxygen, smaller wound, and lower trauma pH versus VSD, suggesting that antibiotic bone cement plus lateral bone repositioning contributes to potentiating the treatment efficacy and reducing the foot ulcer trauma, thereby facilitating rapid recovery. Patients given antibiotic bone cement plus lateral bone repositioning had larger vascular internal diameter and blood flow and better sensory conduction velocity of the common peroneal nerve and the motor conduction velocity of the tibial nerve versus those given VSD, indicating its vascular and neurological benefits. Conclusion: Antibiotic bone cement plus lateral bone repositioning enhances the treatment efficiency, boosts trauma healing, and promotes postoperative functional recovery of patients.

Background: Body mass index (BMI) is a vital risk factor for kidney stones, but physical activity may reduce the incidence of kidney stones. However, it remains unknown whether physical activity reduces the effect of high BMI on kidney stones in diabetes participants.Methods: We included clinical information from 4,008 adult participants with diabetes from the National Health and Nutrition Examination Survey (NHANES) database from 2007 to 2018. Univariate and multivariate logistic regression analyses were used to analyze the relationship between BMI and kidney stones, as well as the risk of BMI and kidney stones in different physical activity subgroups.Results: A total of 4,008 diabetic participants were included in this study, of whom 652 (16.3%) self-reported a history of kidney stones. Logistic regression analysis showed a positive association between BMI and kidney stones. After adjusting for other confounders, the adjusted ORs for the risk of kidney stones was 1.514 (95% CI, 1.134–2.022, p = 0.005) for participants with BMI ≥30 kg/m² among all participants; the risk of kidney stones was elevated (OR = 1.572, 95% CI, 1.134–2.022, p = 0.005) in group without physical activity, and a reduced risk (OR = 1.421, 95% CI, 0.847–2.382, p = 0.183) in the group with physical activity. Furthermore, similar results were found in most subgroups.Conclusion: Our study suggests that high BMI is a risk factor for diabetes kidney stone participants and that physical activity may moderate this relationship to some extent.

Objective. To explore the effect of calcitriol combined with zoledronic acid in posterior cruciate ligament tibial avulsion fractures of the knee joint in patients with diabetic osteoporosis. Methods. Between January 2020 and January 2022, 60 patients with diabetic osteoporosis treated in our hospital were included. All patients underwent knee joint posterior cruciate ligament tibial avulsion fractures, and they were randomized (1 : 1) into the observation group (calcitriol combined with zoledronic acid) and control group (calcitriol). The two groups were compared with respect to the improvement of bone mineral density and bone metabolism indexes, the pain degree (VAS) and knee joint function (Lysholm), and the incidence of refracture. Results. Both groups showed an increasing bone mineral density after treatment, and significant increase was observed in the observation group vs. control group (all ). After treatment, VAS scores decreased in the two groups, and Lysholm scores increased compared to the corresponding values before treatment (all ), with more notable changes in the observation group versus control group (all ). The observation group had fewer cases of refractures than the control group (2 cases vs. 8 cases) ( ). Conclusion. Calcitriol combined with zoledronic acid used in patients with diabetic osteoporosis after the posterior cruciate ligament tibial attachment avulsion fracture of the knee joint yields a promising result in enhancing bone mineral density and bone metabolism indicators, relieving pain, improving knee joint function, and reducing the risk of refracture.
