Effect of two different surgical modalities for pelvic organ prolapse on postoperative wound infection in patients: A meta‐analysis

Abstract

Sacrospinous ligament fixation (SSLF) is widely applied to the treatment of female pelvis organ prolapsed. Contradictory findings have already been reported in the comparison of sacrocolpopexy (SC) with SSLF. The objective of this study is to evaluate the efficacy of SC versus SSLF in treating pelvis organ prolapsed after operation. We conducted a meta-analysis of both operative approaches, including PubMed, Embase, and Cochrane Library. In this research, 822 articles were chosen from three databases, 201 were copied, and 10 were included. Among them, 7248 cases were operated on the prolapsed pelvis. It was found that SSLF surgery could significantly decrease the rate of postoperative wound infection after operation (odds ratio [OR], 0.59; 95% confidence interval [CI], 0.42–0.82; p = 0.001). No statistical significance was found among the SSLF and the SC surgery for the post-operation haemorrhage of the patient (OR, 0.81; 95% CI, 0.23–2.83; p = 0.75). No statistical significance was found among the SSLF and the SC surgery for the postoperative period of the patient's operation (mean difference, −15.46; 95% CI, −52.87 to 21.94; p = 0.42). Applying SSLF surgery to treat pelvic prolapse in women may benefit from a reduction in the number of post-operative wound infections. However, SSLF had no statistical significance with respect to the amount of haemorrhage after operation or operation time.

Effects of clinical nursing pathway on the surgical site wound infection in patients undergoing knee or hip replacement surgery: A meta‐analysis

Abstract

To explore the effect of clinical nursing pathway on wound infection in patients undergoing knee or hip replacement surgery. Computerised searches of PubMed, Web of Science, Cochrane Library, Embase, Wanfang, China Biomedical Literature Database, China National Knowledge Infrastructure databases were conducted, from database inception to September 2023, on the randomised controlled trials (RCTs) of application of clinical nursing pathway to patients undergoing knee and hip arthroplasty. Literature was screened and evaluated by two researchers based on inclusion and exclusion criteria, and data were extracted from the final included literature. RevMan 5.4 software was employed for data analysis. Overall, 48 RCTs involving 4139 surgical patients were included, including 2072 and 2067 in the clinical nursing pathway and routine nursing groups, respectively. The results revealed, compared with routine nursing, the use of clinical nursing pathways was effective in reducing the rate of complications (OR = 0.17, 95%CI: 0.14–0.21, p < 0.001) and wound infections (OR = 0.29, 95%CI: 0.16–0.51, p < 0.001), shortens the hospital length of stay (MD = −4.11, 95%CI: −5.40 to −2.83, p < 0.001) and improves wound pain (MD = −1.34, 95%CI: −1.98 to −0.70, p < 0.001); it also improve patient satisfaction (OR = 7.13, 95%CI: 4.69–10.85, p < 0.001). The implementation of clinical nursing pathways in clinical care after knee or hip arthroplasty can effectively reduce the incidence of complications and wound infections, and also improve the wound pain, while also improving treatment satisfaction so that patients can be discharged from the hospital as soon as possible.

Impact of prophylactic wound closure in colorectal ESD on postoperative wound complications: A meta‐analysis

Abstract

Endoscopic submucosa dissection (ESD) has been applied extensively in the treatment of large intestine tumours due to its high total excision ratio. Nevertheless, there is a high incidence of adverse reactions in colon ESD, and the efficacy of prophylactic ESD following ESD in prevention of postoperative haemorrhage is still disputed. The purpose of this meta-analysis is to evaluate the effectiveness of prophylaxis of wound closure in large intestine ESD after operation. For eligibility, we looked through three databases: PubMed, Embase and Cochrane Library. Heterogenity was measured by means of a chi-square method of Q-statistic and an I2 test. Fixed or random effects models were used for data processing. Based on the retrieval policy, we found a total of 1286 papers, and then we collected nine papers to extract the data. Regarding postoperative haemorrhage, there was a significant reduction in the risk of wound haemorrhage in the wound closure group than in the control group (OR, 0.29; 95% CI, 0.19–0.44 p < 0.0001). No statistical significance was found in the incidence of perforation in the wound closure and the control group (OR, 0.45; 95% CI, 0.19–1.03 p = 0.06). There was a significant reduction in the incidence of postoperation fever among those in the wound closure group than in the control group (OR, 0.37; 95% CI, 0.15–0.93 p = 0.04). Preventive endoscopic closure decreased the rate of ESD in colon disease, but did not significantly decrease the rate of postoperation perforation and postoperative fever. Future research will be required to clarify the risk factors and classify high-risk individuals in order to formulate a cost-effective prevention strategy.

HMOX1 as a therapeutic target associated with diabetic foot ulcers based on single‐cell analysis and machine learning

Abstract

Diabetic foot ulcers (DFUs) are a serious chronic complication of diabetes mellitus and a leading cause of disability and death in diabetic patients. However, current treatments remain unsatisfactory. Although macrophages are associated with DFU, their exact role in this disease remains uncertain. This study sought to detect macrophage-related genes in DFU and identify possible therapeutic targets. Single-cell datasets (GSE223964) and RNA-seq datasets (GSM68183, GSE80178, GSE134431 and GSE147890) associated with DFU were retrieved from the gene expression omnibus (GEO) database for this study. Analysis of the provided single-cell data revealed the distribution of macrophage subpopulations in the DFU. Four independent RNA-seq datasets were merged into a single DFU cohort and further analysed using bioinformatics. This included differential expression (DEG) analysis, multiple machine learning algorithms to identify biomarkers and enrichment analysis. Finally, key results were validated using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and Western bolt. Finally, the findings were validated using RT-qPCR and western blot. We obtained 802 macrophage-related genes in single-cell analysis. Differential expression analysis yielded 743 DEGs. Thirty-seven macrophage-associated DEGs were identified by cross-analysis of marker genes with macrophage-associated DEGs. Thirty-seven intersections were screened and cross-analysed using four machine learning algorithms. Finally, HMOX1 was identified as a potentially valuable biomarker. HMOX1 was significantly associated with biological pathways such as the insulin signalling pathway. The results showed that HMOX1 was significantly overexpressed in DFU samples. In conclusion, the analytical results of this study identified HMOX1 as a potentially valuable biomarker associated with macrophages in DFU. The results of our analysis improve our understanding of the mechanism of macrophage action in this disease and may be useful in developing targeted therapies for DFU.

Effectiveness of SCAR‐Q for assessment of incisional SCAR after implant‐based reconstruction in breast cancer patients: Can it be a tool for incision selection?

Abstract

Incisional scarring is a factor of cosmetic appearance evaluated after breast reconstruction, along with the shape, position, and size of the breast. This study aimed to examine the effect of the incision scar location on patient satisfaction after breast reconstruction. Using the Japanese version of the SCAR-Q, we assessed the scar appearance, symptoms and psychosocial effects. Plastic surgeons performed assessments using the Manchester Scar Scale. The patients were divided into two groups: those with scars on the margins of the breast (MB group) and those with scars in the breast area (IB group). The results revealed that patients in the MB group reported significantly higher satisfaction with the scar appearance and psychological impact than those in the IB group. However, assessments using the Manchester Scar Scale did not reveal any significant differences between the two groups. In conclusion, this study underscores the importance of patient-reported outcomes in the evaluation of scar satisfaction after breast reconstruction. Patients tend to prefer and have higher satisfaction with scars along the breast margin, which offers valuable insights into surgical decisions. Further studies with larger and more diverse sample sizes are required for validation.

Impacts of continuous quality improvement on wound pain in the puncture site of arteriovenous fistula in haemodialysis patient

Abstract

This study analyses the effects of a continuous quality improvement nursing model on wound pain at the arteriovenous fistula (AVF) puncture site in patients undergoing haemodialysis. Forty haemodialysis patients from the First Affiliated Hospital of Chongqing Medical University, from September 2020 to December 2022, were selected as study subjects. They were randomly divided into an observation group and a control group. The control group received conventional nursing care, while the observation group was treated with a continuous quality improvement nursing model. The study compared the impact of these nursing approaches on pain intensity post-AVF puncture, wound visual analogue scale scores, self-rating anxiety scale, self-rating depression scale, quality of life scores and patient satisfaction with nursing care. In the observation group, the proportion of patients experiencing moderate to severe pain during AVF puncture was lower than that in the control group, whereas the proportion of patients with no pain or mild pain was higher (P = 0.008). After nursing, the observation group exhibited significantly lower wound visual analogue scale scores, self-rating anxiety scale scores, and self-rating depression scale scores compared to the control group (P < 0.001), with a significantly higher quality of life score (P < 0.05). The nursing satisfaction rate was 95.00% in the observation group, significantly higher than the 65.00% in the control group (P = 0.018). The continuous quality improvement nursing model significantly reduces wound pain at the AVF puncture site in haemodialysis patients, alleviates negative emotions, enhances the quality of life, and achieves high patient satisfaction. It is thus a highly recommendable approach in nursing practice.

Effect of angiogenesis inhibitors on wound healing in patients with ovarian cancer: A meta‐analysis

Abstract

Angiogenic inhibitors have been demonstrated to inhibit tumour cells in ovarian carcinoma, but the initial data are not accurate enough to indicate the influence of these drugs on the post-therapy wound healing. In order to assess the effect of angiogenic inhibitors on the treatment of wound healing in ovarian carcinoma, we performed a meta-analysis of related literature. For this meta-analysis, we looked up the data from 4 databases: PubMed, EMBASE, Web of Science and the Cochrane Library. All literature searches were performed up to October 2023. The ROBINS-I tool was applied to evaluate the risk of bias in the inclusion trials, and statistical analysis was performed with RevMan 5.3. In this research, 971 related research were chosen, and 9 of them were selected. These studies were published between 2013 and 2023. In all 9 trials, a total of 3902 patients were enrolled. There was a significant reduction in the risk of wound infection in the control group than in those who received angiogenesis inhibitors (OR, 0.66; 95% CI, 0.49–0.89 p = 0.007). The risk of developing an abscess was not significantly different from that of those who received angiogenesis inhibitors (OR, 0.80; 95% CI, 0.20–3.12 p = 0.74). The risk of perforation in the control group was smaller than that in those receiving angiogenic inhibitors (OR, 0.25; 95% CI, 0.11–0.56 p = 0.0006). There was a significant increase in the risk of injury and GI perforation in women who received angiogenic inhibitors than in the control group. But the incidence of abscess did not differ significantly among the two groups.

The impact of early nutritional support on postoperative wound healing in patients with complex fractures: A meta‐analysis review

Abstract

Complex fractures present significant challenges in orthopaedic surgery, particularly in terms of postoperative wound healing. Nutritional status plays a crucial role in the recovery process, with early nutritional support potentially influencing wound healing outcomes. This meta-analysis aimed to assess the impact of early nutritional interventions on postoperative wound healing and scar formation in patients with complex fractures. From an initial pool of 1742 articles, 7 studies were selected for analysis. The results revealed that preoperative nutritional support significantly improved early wound healing, as indicated by lower REEDA scores (SMD = −14.06, 95% CI: [−16.79, −11.32], p < 0.01) 1 week post-surgery. Furthermore, there was a notable reduction in scar formation, as demonstrated by lower Manchester Scar Scale scores (SMD = −25.03, 95% CI: [−30.32, −19.74], p < 0.01) 3 months post-surgery. These findings highlight the importance of incorporating nutritional strategies into the management of complex fractures to optimize postoperative recovery.

Identification and clinical validation of the role of anoikis‐related genes in diabetic foot

Abstract

This study aims to investigate the role of anoikis-related genes in diabetic foot (DF) by utilizing bioinformatics analysis to identify key genes associated with anoikis in DF. We selected the GEO datasets GSE7014, GSE80178 and GSE68183 for the extraction and analysis of differentially expressed anoikis-related genes (DE-ARGs). GO analysis and KEGG analysis indicated that DE-ARGs in DF were primarily enriched in apoptosis, positive regulation of MAPK cascade, anoikis, focal adhesion and the PI3K-Akt signalling pathway. Based on the LASSO and SVM-RFE algorithms, we identified six characteristic genes. ROC curve analysis revealed that these six characteristic genes had an area under the curve (AUC) greater than 0.7, indicating good diagnostic efficacy. Expression analysis in the validation set revealed downregulation of CALR in DF, consistent with the training set results. GSEA results demonstrated that CALR was mainly enriched in blood vessel morphogenesis, endothelial cell migration, ECM-receptor interaction and focal adhesion. The HPA database revealed that CALR was moderately enriched in endothelial cells, and CALR was found to interact with 63 protein-coding genes. Functional analysis with DAVID suggested that CALR and associated genes were enriched in the phagosome component. CALR shows promise as a potential marker for the development and treatment of DF.

Shame in patients undergoing ureterostomy: A cross‐sectional survey

Por: Qin Li · Lin Zhuo · Ting Zhang

Abstract

Shame has an important impact on the mental health and quality of life of patients. The shame in patients with ureterostomy after cystectomy remains unclear. This survey aimed to evaluate the status quo and influencing factors of shame in patients with ureterostomy after cystectomy, to provide support for the clinical care. Patients with ureterostomy after cystectomy treated in the wound stomy clinic of a third-class hospital from 1 June 2022 to 31 July 2023 were included. General data questionnaire and social impact scale (SIS) were used for data collection. Univariate and multiple linear regression analysis were performed to evaluate the influencing factors of shame in patients with ureterostomy after cystectomy. One hundred and sixty four patients with ureterostomy after cystectomy were included. The total score of shame in patients with ureterostomy was (60.75 ± 6.31), which was in the high level. Age (r = 0.442), home place (r = 0.427), per capita monthly household income (r = 0.605), self-care ability (r = 0.597) and complications of stoma (r = 0.542) were correlated with the SIS score in patients with ureterostomy after cystectomy (all p < 0.05). Multiple linear regression analyses indicated that age, home place, per capita monthly household income, self-care ability and complications of stoma were the influencing factors of SIS score in patients with ureterostomy after cystectomy (all p < 0.05). The five variables explained 64.5% of the patients' sense of shame variation. Patients with ureterostomy after cystectomy have a serious sense of shame in the early stage after operation and there are many influencing factors. Health care providers should take early nursing interventions targeted on those influencing factors to reduce the patients' sense of shame.

Effect of passive versus active abdominal drainage on wound infection after pancreatectomy: A meta‐analysis

Abstract

Following pancreatic resection, there may be a variety of complications, including wound infection, haemorrhage, and abdominal infection. The placement of drainage channels during operation may decrease the chances of postoperative complications. However, what kind of drainage can decrease the rate of postoperative complications is still a matter of debate. The purpose of this research is to evaluate the efficacy of both active and passive drainage for post-operation wound complications. From the beginning of the database until November 2023, EMBASE, the Cochrane Library and the Pubmed database have been searched. The two authors collected 2524 related studies from 3 data bases for importation into Endnote software, and 8 finished trials were screened against the exclusion criteria. Passive drainage can decrease the incidence of superficial wound infection in postoperative patients with pancreas operation (Odds Ratio [OR], 1.30; 95% CI, 1.06–1.60 p = 0.01); No statistically significant difference was found in the incidence of deep infections among the two groups (OR, 1.51; 95% CI, 0.68–3.36 p = 0.31); No statistical significance was found for the rate of haemorrhage after active drainage on the pancreas compared with that of passive drainage (OR, 0.72; 95% CI, 0.29–1.77 p = 0.47); No statistically significant difference was found in the rate of death after operation for patients who had received a pancreas operation in active or passive drainage (OR, 0.90; 95% CI, 0.57–1.42 p = 0.65); On the basis of existing evidence, the use of passive abdominal drainage reduces postoperative surface wound infections in patients. But there were no statistically significant differences in the risk of severe complications, haemorrhage after surgery, or mortality. However, because of the limited sample size of this meta-analysis, it is necessary to have more high-quality research with a large sample size to confirm the findings.

The application of topical antibiotics for the prevention of infections in primary joint arthroplasty. An umbrella review of systematic reviews and meta‐analysis

Abstract

This umbrella review aim to explore the effect of topical antibiotics in infection prevention after primary joint arthroplasty, and provide a specific theoretical basis for clinical treatment. The review process was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched PubMed, EMBASE, Medline, and the Cochrane Library on infection prevention by topical antibiotics from inception to 10 April 2023. The two researchers individually and strictly screened the literature according to the inclusion and exclusion criteria, performed the literature quality evaluation and data extraction, and used Stata 17 for data analysis. This study included six studies with one systematic review and five meta-analyses. The pooled analysis showed that topical antibiotic administration effectively reduced the incidence of overall infection and periprosthetic joint infection. However, it does not reduce the risk of superficial infection. Besides, the topic of antibiotics significantly increases the incidence of other sterile complications of the incision. According to the current evidence, topical application of antibiotics can reduce the incidence of overall infection and periprosthetic joint infection after primary joint arthroplasty. Although it increases the incidence of complications such as delayed healing of incisions, the pros and cons should be weighed in clinical decision making. However, they should not be discarded due to side effects.

A retrospective cohort study of the impact of COVID‐19 infection control measures on surgical site infections in an academic hospital setting

Abstract

Previous studies show that both the frequency of surgeries and incidence of surgical site infections (SSIs) have been lower during the coronavirus disease 2019 (COVID-19) pandemic. This study's purpose is to analyse the possible association of the COVID-19 epidemic-related increased health measures, such as protective equipment and products, increased hand hygiene and restrictions imposed, on the incidence of SSIs in an academic medical centre. We designed a single-centre, retrospective cohort study and collected data on the frequency of surgeries and the incidence of SSIs, among patients who had surgeries pre- and post-COVID-19 pandemic. Besides the intervention and outcome variable, we sought information on patient gender, surgery type, body mass index (BMI), smoking, and type II diabetes mellitus. We used Wald 95% confidence interval (95% CI) and the p values of the odds ratio (OR) to report results. Of the N = 24 098 surgeries performed in this hospital, there were 269 patients who reported post-surgical SSIs in this hospital between March 2019 and March 2021. The OR of developing a post-surgical SSI was 0.40 (95% CI: 0.33–0.57, p < 0.05; adjusted for confounders 0.39 [95% CI: 0.30–0.52, p < 0.05]) among patients who had surgery under post-pandemic infection control measures, as compared to patients who had surgery under pre-pandemic usual care infection control measures. Our significant results conclude that an association may exist between the enhanced infection control measures used during the COVID-19 pandemic and lower incidence of SSIs we observed during this period.

Effects of predictive nursing interventions on pressure ulcer in elderly bedridden patients

Abstract

The study explores the impact of predictive nursing interventions on pressure ulcers (PUs) in elderly bedridden patients. A total of 120 elderly bedridden patients from the Central Hospital of Enshi Tujia and Miao Autonomous Prefecture between August 2019 and August 2023 were selected as the subjects of the study and were randomly divided into an observation group and a control group using a random number table method. The control group received conventional nursing care, while the observation group received predictive nursing interventions. The study compared the incidence of PUs, Braden scale scores, the onset time of PUs, self-rating anxiety scale (SAS) scores, self-rating depression scale (SDS) scores, and nursing satisfaction between the two groups. In elderly bedridden patients, the application of predictive nursing interventions significantly reduced the incidence of PUs (p < 0.001), significantly lowered the SAS and SDS scores (p < 0.001), and also significantly increased Braden scale scores (p < 0.001) and delayed the onset time of PUs (p < 0.001). Additionally, it improved patients' nursing satisfaction (p = 0.008). Predictive nursing interventions in elderly bedridden patients have good application effects, reducing the occurrence of PUs, delaying the time of onset in patients, improving patients' negative emotions and enhancing nursing satisfaction rates. It is worthy of widespread use.

The effect of traditional Chinese medicine soaking method on the healing of diabetic foot ulcers: A meta‐analysis

Abstract

Foot infections, sores or deep tissue damage from diabetes can be a serious psychological and physical injury. This paper aims at making meta-analyses on the therapeutic effects of traditional Chinese medicine (TCM) on diabetic foot ulcers. The Chinese National Knowledge Infrastructure, VIP Database, Wanfang Database and so on, has conducted a randomized controlled trial to evaluate the clinical effect of TCM soaking method for diabetes patients with diabetes. Literature has been determined to be included by computer search and by hand rough checks. The search period was from the creation of the database to October 2023. Review Manager 5.3 was used to analyse the meta data and evaluate it systematically. Altogether, 479 research was conducted in China's data base and 20 of them were eventually collected for the final statistical analysis. In all, 1361 patients were enrolled in the trials. The results indicated that TCM immersion in diabetic foot resulted in significantly improved obvious wound healing (OR, 3.2; 95% CI, 2.5, 4.09, p < 0.0001); results showed that TCM immersion therapy significantly increased the efficiency of effective wound healing (OR, 4.55; 95% CI, 3.25, 6.37, p < 0.001). Statistical significance was found. Using Egger's approach to detect publishing bias suggests that there is no risk of publishing bias in terms of marked wound healing and effective healing. Traditional Chinese drug immersion can increase obviously the recovery ratio and the effective recovery ratio of diabetic foot.

Evaluating the role of wound‐healing genes in conjunction with stool routine and serum tumor markers for colorectal cancer diagnosis and prognostic implications

Abstract

Colorectal cancer is a common malignant digestive tract tumour with high morbidity and mortality. Early detection, treatment and diagnosis are crucial for preventing and treating colorectal cancer, which develops through multi-stage accumulation and gene participation, affecting tumour marker levels. Chronic wounds can lead to the development of certain cancers, such as colorectal cancer. The prolonged inflammation and tissue repair caused by chronic wounds can trigger cellular changes, potentially promoting cancerous cell growth in the colon. The formation and progression of colorectal cancer involve changes in tumour markers, such as carcinoembryonic antigen (CEA), sugar chain antigen 19–9 (CA199) and CA125. This study explores the clinical application value of a stool routine combined with serum tumour marker detection in diagnosing colorectal cancer. The experiment team examined the clinical information of 56 colorectal cancer patients alongside a control group of 56 healthy patients. Distinct stool characteristics and heightened occult blood rates were evident in colorectal cancer cases. The combined approach integrating stool routine and serum tumour markers improved diagnostic accuracy, displaying enhanced sensitivity and specificity compared with individual markers or stool routines alone. Bioinformatics analysis indicated increased CEA and CA125 levels in colorectal cancer tissues versus normal tissues, hinting at potential prognostic implications. Exploring wound-healing genes like Vascular Endothelial Growth Factor A (VEGFA), Tumour Protein 53 (TP53) and Transforming Growth Factor Alpha (TGFA) revealed heightened expression in colorectal cancer, suggesting their potential role in disease progression. These markers showed associations with various immune cell types, suggesting their impact within the tumour microenvironment (p < 0.05). Single-cell RNA sequencing data highlighted varying CEA expressions across different cell populations in colorectal cancer. The findings indicated that integrating clinical assessments with accurate biomarkers may provide valuable insights into prognostic implications.

YouTube as a source of information for pressure injury: Quality assessment and content analysis

Abstract

We aimed to assess the quality and reliability of pressure injury-related videos uploaded on YouTube, analyse the sources and contents, and examine the correlation between video parameters. We searched YouTube using two keywords, “pressure ulcer” and “pressure sore”, on August 20, 2022. We sorted the videos according to their number of views and included the top 100 videos for each keyword. The quality of videos was assessed using the Global Quality Scale (GQS), while their reliability was evaluated by the modified DISCERN (mDISCERN) tool. In addition, we evaluated the videos in which content was included, analysed the correlations and differences between GQS, mDISCERN, and video parameters. We initially found a total of 100 videos for each keyword and finally included and analysed 77 videos. The mean scores for the mDISCERN and GQS were 2.35 ± 0.98 and 3.09 ± 0.99, respectively. Both GQS and mDISCERN showed statistically significant correlations with each other (rho = 0.54, p < 0.0001*) and with the length of the videos, respectively (rho = 0.36, p = 0.001*), (rho = 0.29, p = 0.01*). Of the videos created by physicians, 8 (57.1%) included content related to treatment, while of the videos created by nonphysician health personnel, 22 (57.9%) included content related to prevention. Analysing whether there were differences in video parameters based on the sources, we observed significant differences between sources in GQS (p < 0.0001*), mDISCERN (p < 0.0001*), and video length (p = 0.001*). In the post-hoc analysis, videos uploaded by physicians or nonphysician health personnel showed higher quality and reliability than videos uploaded by other sources. Therefore, the results of this study could be useful for healthcare providers, as well as patients and caregivers, to search for high-quality and reliable YouTube videos related to pressure injury.

Effects of photodynamic therapy in patients with infected skin ulcers: A meta‐analysis

Abstract

The purpose of the meta-analysis was to evaluate and compare the photodynamic therapy's effectiveness in treating infected skin wounds. The results of this meta-analysis were analysed, and the odds ratio (OR) and mean difference (MD) with 95% confidence intervals (CIs) were calculated using dichotomous or contentious random- or fixed-effect models. For the current meta-analysis, 6 examinations spanning from 2013 to 2021 were included, encompassing 154 patients with infected skin wounds were the used studies' starting point. Photodynamic therapy had a significantly lower wound ulcer size (MD, −4.42; 95% CI, −7.56–−1.28, p = 0.006), better tissue repair (MD, −8.62; 95% CI, −16.76–−0.48, p = 0.04) and lower microbial cell viability (OR, 0.13; 95% CI, 0.04–0.42, p < 0.001) compared with red light exposure in subjects with infected skin wounds. The examined data revealed that photodynamic therapy had a significantly lower wound ulcer size, better tissue repair and lower microbial cell viability compared with red light exposure in subjects with infected skin wounds. However, given that all examinations had a small sample size, consideration should be given to their values.

Nomogram for predicting surgical site infections in elderly patients after open lumbar spine surgery: A retrospective study

Abstract

The aim of this study is to develop a nomogram to assess the risk of surgical site infection in elderly patients undergoing open lumbar spine surgery and explore related risk factors. We reviewed the records of 578 elderly patients who had undergone open lumbar spine surgery. The clinical parameters were subjected to lasso regression and logistic regression analyses. Subsequently, a nomogram was constructed to predict the risk of postoperative surgical site infection and validated using bootstrap resampling. A total of 578 patients were included in the analysis, of which 17 were diagnosed as postoperative surgical site infection. Following the final logistic regression analysis, obesity, hypoalbuminemia and drinking history were identified as independent risk factors and subsequently incorporated into the nomogram. The nomogram demonstrated excellent discrimination, with an area under the receiver-operating characteristic curve of 0.879 (95% CI 0.769 ~ 0.989) after internal validation. The calibration curve exhibited a high level of consistency. Decision curve analysis revealed that this nomogram had greater clinical value when the risk threshold for surgical site infection occurrence was >1% and <89%. We had developed a nomogram for predicting the risk of postoperative surgical site infection in elderly patients who had undergone open lumbar spine surgery. Validation using bootstrap resampling demonstrated excellent discrimination and calibration, indicating that the nomogram may hold potential clinical utility as a simple predictive tool for healthcare professionals.
