The efficacy and safety of non-surgical treatment of diabetic foot wound infections and ulcers: A systemic review and meta-analysis.

This meta-analysis evaluates the efficacy and safety of non-surgical treatments for diabetic foot ulcers and infections. After a rigorous literature review, seven studies were selected for detailed analysis. The findings demonstrate that non-surgical treatments significantly reduce wound infection rates (standardized mean difference [SMD] = -15.15, 95% confidence interval [CI]: [-19.05, -11.25], p < 0.01) compared to surgical methods. Ulcer healing rates were found to be comparable between non-surgical and surgical approaches (SMD = 0.07, 95% CI: [-0.38, 0.51], p = 0.15). Importantly, the rate of amputations within 6 months post-treatment was significantly lower in the non-surgical group (risk ratio [RR] = 0.19, 95% CI: [0.09, 0.41], p < 0.01). Additionally, a lower mortality rate was observed in patients treated non-surgically (RR = 0.28, 95% CI: [0.13, 0.59], p < 0.01). These results affirm the effectiveness and safety of non-surgical interventions in managing diabetic foot ulcers, suggesting that they should be considered a viable option in diabetic foot care.

Cardiac myxoma shedding leads to lower extremity arterial embolism: A case report.

BACKGROUND: Left cardiac myxoma (CM) is the most common benign tumor of primary cardiac tumors, but because of its special position caused by pathological physiology change, caused by the complications of the heavier, the surface is often accompanied by blood clots, once fall out, it causes peripheral vascular embolization, such as acute lower limb artery embolization, harmfulness is large, high morbidity, and easy to occur repeatedly. CASE SUMMARY: A 67-year-old male patient suddenly appeared numbness and weakness of the left lower limb and could not walk without obvious incentive. The patient was finally diagnosed as left CM complicated with acute lower limb arterial embolism after completing cardiac ultrasound, computer tomography angiography, and histopathological analysis, such as hematoxylin-eosin stain staining, immunohistochemistry and special staining including alcian blue staining and periodic acid schiff staining. Arterial thrombosis was removed successfully by femoral artery thrombectomy, postoperative numbness and weakness of the patient's left lower limb disappeared, skin temperature became warm, and dorsal foot artery pulsation was accessible. The patient was readmitted to the hospital 8 mo after discharge for left atrial mass resection, and was diagnosed as CM by postoperative histopathological examination. CONCLUSION: Although CM is rare, it may be considered as the source of embolism in patients with acute limb ischemia. Repeated loss of thrombus on the tumor and its surface may lead to repeated embolism of peripheral vessels. Cardiac ultrasound is helpful for early diagnosis. Here, we use this case report to highlight left CM as an important cause of acute limb ischemia and to report our experience in the diagnosis and treatment of lower limb arterial embolism caused by CM detachment.

Association Between Red Blood Cell Distribution Width-to-Albumin Ratio and Prognosis of Patients with Aortic Aneurysms.

OBJECTIVE: Red blood cell distribution width (RDW) is a predictor of adverse outcomes in aortic aneurysms. Recent recommendations suggest that combining RDW with other biomarkers could yield better results. We, therefore, propose evaluating the biomarker of vascular aging, albumin with RDW to predict the risk of aortic aneurysms. This study aims to explore whether the combination of RDW with albumin can effectively predict the prognosis of aortic aneurysm patients. METHODS: This retrospective cohort study was conducted among adults (age >18) with aortic aneurysms in the Medical Information Mart for Intensive Care Database III V1.4 (MIMIC-III). RAR was measured according to the red blood cell distribution width and albumin. The primary outcome was the 30-day mortality rate, and the secondary outcome was the 90-day and one-year mortality rates. Estimation of hazard ratios (HR) was obtained from Cox regression models for all-cause mortality related to red cell distribution width-to-albumin ratio (RAR) values. RESULTS: In total, 312 patients were involved, with an average age of 74.9 ± 10.9 years and an average RAR value of 5.4 ± 1.6 mL/g. In 30 days for all-cause mortality, the HR (95% CI) in the highest RAR group (>5.8 mL/g) in tertiles was 2.54 (1.25, 5.14) in the unadjusted model, with a significant difference compared with the reference group (P < 0.05). After adjusting for race, gender and age, there was still a correlation (P < 0.05), and the HR (95% CI) was 2.51 (1.23, 5.10). Further adjustment of possible covariates showed similar correlation in model 3 (P < 0.05), and HR (95% CI) was 2.66 (1.17, 6.01). Multivariable logistic regression shows that RAR is an independent risk factor for the outcome of aortic aneurysms after adjusting the covariates. In the subgroup analysis, we analyzed the patient's complications, and no significant interaction was observed. CONCLUSION: RAR is a risk factor for patients with aortic aneurysms. However, more in-depth research is warranted to further analyze and substantiate our findings on the role of RAR in aortic aneurysm patients.

[Accuracy of endoscopic ultrasound in the preoperative staging and the guidance of transanal endoscopic microsurgery for rectal cancer].

OBJECTIVE: To explore the accuracy of endoscopic ultrasound (EUS) in preoperative staging of rectal cancer and to guide the treatment of transanal endoscopic microsurgery (TEM) in early rectal cancer. METHODS: Clinical data of 80 patients with rectal cancer receiving EUS examination for preoperative staging in our department between June and December 2012 were retrospectively analyzed. Consistence comparison of EUS preoperative staging and pathological staging was performed to identify the accuracy of EUS preoperative staging. All the patients underwent operation within 1 week after EUS examination. According to preoperative staging, early rectal cancer(Tis or T1N0M0) patients with lesions less 20 cm to anus underwent TEM. RESULTS: The overall accuracy of EUS for preoperative T stage was 68.8%(55/80), and for T1, T2, T3, T4 was 91.3%(73/80), 83.8%(68/80), 77.5%(62/80), 85.0%(67/80), which had a good consistence with postoperative pathological T staging(Kappa=0.562). The overall accuracy of EUS for preoperative N stage was 52.7%(39/74), and for N0, N1, N2 stage was 64.9%(48/74), 55.4%(41/74), 85.1%(63/74), which had a poor consistence with postoperative pathological N staging(Kappa=0.235). Six patients underwent TEM successfully, with mean operation time 99(65 to 123) min, without intraoperative and postoperative complication, and were discharged 2-3 days after operation. Enteroscope showed good recovery 1 month later. Pathology confirmed that all the lesions were early rectal cancer. During postoperative follow-up of 14.8 (11 to 19) months, there was no local recurrence and distant metastasis. CONCLUSION: Preoperative EUS has a good accuracy with pathologic T stage, and can guide TEM in early rectal cancer.
