Although potential risk factors for sternal wound infection (SWI) have been extensively studied, the onset time of SWI and different risk factors for superficial and deep SWI were rarely reported. This nested case–control study aims to compare the onset time and contributors between superficial and deep SWI. Consecutive adult patients who underwent cardiac surgery through median sternotomy in a single center from January 2011 to January 2021 constituted the cohort. The case group was those who developed SWI as defined by CDC and controls were matched 6:1 per case. Kaplan–Meier analysis, LASSO and univariate and multivariate Cox regressions were performed. A simple nomogram was established for clinical prediction of the risk of SWI. The incidence of SWI was 1.1% (61 out of 5471) in our cohort. Totally 366 controls were matched to 61 cases. 26.2% (16 of 61) SWI cases were deep SWI. The median onset time of SWI was 35 days. DSWI had a longer latency than SSWI (median time 46 days vs. 32 days, p = 0.032). Kaplan–Meier analyses showed different time-to-SWI between patients with and without DM (p = 0.0011) or MI (p = 0.0019). Multivariate Cox regression showed that BMI (HR = 1.083, 95% CI: 1.012–1.116, p = 0.022), DM (HR = 2.041, 95% CI: 1.094–3.805, p = 0.025) and MI (HR = 2.332, 95% CI: 1.193–4.557, p = 0.013) were independent risk factors for SWI. Superficial SWI was only associated with BMI (HR = 1.089, 95% CI: 1.01–1.175, p = 0.027), while deep SWI was associated with DM (HR = 3.271, 95% CI: 1.036–10.325, p = 0.043) and surgery time (HR = 1.004, 95% CI: 1.001–1.008, p = 0.027). The nomogram for SWI prediction had an AUC of 0.67, good fitness and clinical effectiveness as shown by the calibration curve and decision curve analyses. BMI, DM and MI were independent risk factors for SWI. DSWI had a longer latency and different risk factors compared to SSWI. The nomogram showed a fair performance and good effectiveness for the clinical prediction of SWI.
This research is intended to explore the influence of second and first degree closure methods on the degree of wound pain and swelling of the face following the removal of the mandible. For the purpose of this study, three data sets, including PubMed and Embase, were selected. A separate statistical analysis was conducted on the choice of the trial, the collection of data and the risk of bias. Differences between trials were analysed with a chi-square approach, with data analyses dependent on I 2. A sensitivity analysis was conducted, and a possible publication bias was evaluated. Ultimately, nine qualifying trials were chosen out of an original pool of 1922 related trials following an in-depth evaluation under the eligibility and exclusion criteria, as well as a follow-up screening. The results indicated that there was no statistically significant change in the degree of post-operation pain after 1 day operation between one or secondary closures of treatment (MD, −0.46; 95% CI, −0.93, 0.01, p = 0.06); the results showed that there were no statistically significant differences in post-operation wound pain after 3 days in two group (MD, −0.15; 95% CI, −0.68, 0.37, p = 0.56); the results showed that there were no statistically different effects on the post-operation wound pain after the 7th day in two groups (MD, −0.14; 95% CI, −0.31, 0.03, p = 0.1). The results showed that there were no statistically different effects on the post-operation wound pain after the 1 day in two groups (MD, −0.26; 95% CI, −0.38, −0.13, p < 0.0001); on the 3rd day after surgery, the face was significantly smaller swelling in the secondary closure of closure compared with the first-stage closure group (MD, −0.70; 95% CI, −1.40, −0.00, p = 0.05). While there is no obvious effect on post-operation wound pain in patients with mandibular surgery, there is significant difference in post-operation face swelling. The findings do not support a preference for any of these methods.
The research was conducted to examine the correlation between nutritional status and wound healing in individuals who were receiving treatment for head and neck cancer. Specifically, this study sought to identify crucial nutritional factors that influenced both the recovery process and efficacy of the treatment. From February 2022 to September 2023, this cross-sectional study was undertaken involving 300 patients diagnosed with head and neck cancer who were treated at Tianjin Medical University Cancer Institute and Hospital, Tianjin, China. In order to evaluate nutritional status, body mass index (BMI), serum protein levels and dietary intake records were utilized. The assessment of wound healing was conducted using established oncological wound healing scales, photographic documentation and clinical examinations. After treatment, we observed a noteworthy reduction in both BMI (p < 0.05) and serum albumin levels (p < 0.05). There was slightly increased prevalence of head and neck cancer among males (61.0%, p < 0.05). Over the course of 6 months, significant enhancement in wound healing scores was noted, exhibiting overall improvement of 86% in the healing process. An inverse correlation was identified between nutritional status and wound healing efficacy through multivariate analysis. A logistic regression analysis revealed a significant positive correlation (p < 0.05) between elevated levels of serum protein and total lymphocytes and enhanced wound healing. Conversely, negative correlation (p < 0.05) was observed between larger wound size at baseline and healing. The research findings indicated noteworthy association between malnutrition and impaired wound repair among individuals diagnosed with head and neck cancer. The results underscored the significance of integrating nutritional interventions into therapeutic protocol in order to enhance clinical results. This research study provided significant contributions to the knowledge of intricate nature of head and neck cancer management by advocating for multidisciplinary approach that incorporates nutrition as the critical element of patient care and highlighted the importance of ongoing surveillance and customized dietary approaches in order to optimize wound healing and treatment efficacy.
