Diabetic foot ulcer (DFU) is one of the most serious complications of diabetes mellitus. Considering complicated conditions, poor general condition, severe infection and poor outcomes as the feature characteristics of Chinese DFU patients, comprehensive and systematic evaluation, including general condition, region of the foot, and psychological status, is essential and fundamental for successful treatment. This commentary summarizes the evaluation contents in scientific and standardized diagnosis and treatment of diabetic foot ulcer, and looking forward to reducing morbidity, recurrence rate and mortality, and increasing limb salvage rate.
ObjectiveTo evaluate the effect of post mastectomy radiation therapy (PMRT) on breast reconstruction after mastectomy in breast cancer patients, in order to provide evidence support for clinical treatment decision.MethodsFive databases searched in the current study include the Cochrane Library, PubMed, CNKI, VIP and WanFang database. A systematic search for control trials was performed in each database from the starting date of each database to March 1, 2021. After the two evaluators independently selected literatures, extracted data and conducted quality evaluation according to the inclusion and exclusion criteria, the meta analysis was carried out by Revman 5.3 software.ResultsA total of 9 cohort studies (3 447 cases) were included, including 699 cases in PMRT group and2 748 cases in non-radiotherapy group. The results of meta-analysis showed that: PMRT was associated with significant increase in capsular contracture. The incidence of capsular contracture increased from 4.34% in the non-radiotherapy group to 34.10% in patients receiving PMRT [OR=9.25, 95%CI (3.76, 22.78), P<0.000 01]. In addition, PMRT was associated with a significant increase in incidences of reconstructive failure [OR=2.55, 95%CI (1.74, 3.74), P<0.000 01] and revisional surgery [OR=2.24, 95%CI (1.58, 3.18), P<0.000 01]. Moreover it was associated with a significant reduction in patient satisfaction [OR=0.29, 95%CI (0.15, 0.57), P=0.000 30] and cosmetic outcome [OR=0.26, 95%CI (0.15, 0.43), P<0.000 01].ConclusionThis meta-analysis demonstrates that breast cancer patients who received PMRT after breast reconstruction, the rate of adverse events is increased and patients’ satisfaction and cosmetic outcome are decreased.
ObjectiveTo systematically evaluate the risk prediction models for postoperative pulmonary infection in patients with esophageal cancer, providing an objective basis for clinical selection and optimization of models. MethodsA systematic search was conducted in Chinese and English databases such as VIP, Wanfang, CNKI, PubMed, Cochrane Library, EMbase, Web of Science, and CBM for studies related to the risk prediction models of postoperative pulmonary infection in patients with esophageal cancer from the inception to September 30, 2024. The PROBAST tool was used to assess the quality of prognostic model research, and the RevMan 5.4 software was used for meta-analysis of predictive factors. ResultsA total of 17 articles were included, containing 26 pulmonary infection risk prediction models. The area under the receiver operating characteristic curve (AUC) ranged from 0.627 to 0.942, among which 22 models had good predictive performance (AUC>0.7). Quality assessment through the PROBAST tool revealed that all 17 articles had a high risk of bias. Meta-analysis results showed that common predictive factors for postoperative pulmonary infection in esophageal cancer included smoking history (OR=1.97), smoking index ≥200 (cigarettes-years) (OR=4.38), smoking index ≥400 (cigarettes-years) (OR=2.00), age (OR=1.39), comorbid diabetes (OR=2.13), comorbid emphysema or chronic obstructive pulmonary disease (OR=1.55), low plasma albumin levels (OR=1.17), prognostic nutritional index (OR=4.45), history of related lung diseases (OR=2.10), tumor location (OR=2.32), surgical approach (OR=2.21), operation time (OR=1.73), preoperative serum calcitonin levels (OR=3.06), anastomotic leakage (OR=3.39), reduced forced expiratory volume in the first second/forced vital capacity ratio (OR=0.86), and hoarseness (OR=2.23). ConclusionAt present, the risk prediction models for postoperative pulmonary infection in esophageal cancer are still in the stage of continuous development and optimization, and their research quality needs to be further improved. Future research can refer to the predictive factors summarized in this study based on meta-analysis, combined with clinical practice, to select appropriate methods to construct and validate the risk prediction models for postoperative pulmonary infection in esophageal cancer, thus providing early targeted preventive strategies for high-risk patients.
