Comparative effectiveness of pericapsular nerve group block versus fascia iliac compartment block on postoperative wound pain management in patients undergoing hip fracture surgery: A systematic review and meta‐analysis

Abstract

Hip fracture surgeries are challenging, with postoperative pain management being a critical component of patient care. This systematic review and meta-analysis aimed to compare the effectiveness of Pericapsular nerve group block (PENGB) and fascia iliac compartment block (FICB) in postoperative wound pain management for patients undergoing hip fracture surgery. The study followed the PRISMA guidelines and was structured around the PICO framework. Comprehensive searches were conducted across PubMed, Embase, Web of Science, and the Cochrane Library. Inclusion criteria were limited to RCTs comparing the effectiveness of PENGB and FICB in adult patients undergoing hip fracture surgery. Key outcomes included pain control effectiveness, safety, and complication incidence. The quality of studies was assessed using the Cochrane Collaboration's risk of bias tool. Statistical heterogeneity was evaluated using I 2 statistics, and meta-analysis effect values were calculated using random-effects or fixed-effect models, depending on the degree of heterogeneity. The search identified 1095 articles, with 5 studies meeting inclusion criteria. The meta-analysis revealed that PENGB and FICB were comparable in managing postoperative pain and opioid consumption. However, PENGB significantly reduced the incidence of quadriceps muscle weakness (RR = 0.12, p < 0.05) and did not increase the risk of PONV (RR = 1.36, p = 0.51), suggesting its advantage in maintaining motor function without adding to PONV complications. No significant publication bias was detected. PENGB is comparable to FICB in pain and opioid consumption management after hip fracture surgeries. Its significant benefit lies in reducing the incidence of quadriceps muscle weakness, facilitating better postoperative mobility. Additionally, PENGB does not increase the risk of postoperative nausea and vomiting, underlining its suitability for comprehensive postoperative care in hip fracture patients.

Systematic review and network meta‐analysis of mesenchymal stem cells in treating diabetic skin ulcers in animal models

Abstract

Background

Diabetic cutaneous ulcers often pose considerable challenges in the healing process. These challenges stem from factors including inadequate perfusion of the ulcer's surrounding environment, persistent inflammation, tissue damage and microbial proliferation. The existing standard treatment modalities prove insufficient in fully addressing the complex pathogenesis of these ulcers. As a novel approach, researchers are exploring cellular therapies employing mesenchymal stem cells (MSCs) for the treatment of diabetic skin ulcers. MSCs are readily found in various tissues, including bone marrow, adipose tissue, placenta, amniotic membrane, amniotic fluid and umbilical cord. However, the optimal source of MSCs for effectively treating diabetic skin ulcers remains a topic of ongoing discussion.

Methods

We conducted a comprehensive search of Embase, PubMed and Web of Science databases, spanning from their inception to November 2022. Subsequently, we rigorously screened the literature following predetermined inclusion and exclusion criteria and evaluated the quality of the selected studies using the SYRCLE scale. Finally, the included literature underwent analysis, employing the Bayesian school of thought-based R language. To ensure transparency and accountability, we registered this study with PROSPERO's International Systematic Review Prospective Registry, with the Registration ID: CRD42023387421.

Results

We included a total of 11 articles in our analysis, all of which were randomized controlled studies involving 218 animal models. Among these studies, two utilized adipose-derived MSCs, six employed bone marrow-derived MSCs, one utilized amniotic membrane-derived MSCs and three utilized umbilical cord-derived MSCs. Our network meta-analysis results revealed that there were no statistically significant differences in the healing rates of diabetic skin ulcers among MSCs derived from amniotic membrane, adipose tissue, umbilical cord and bone marrow on days 7–8, 10–12 and 12–14. Notably, according to the probability ranking table, the most effective treatment for diabetic wounds was found to be amniotic membrane-derived MSCs.

Conclusion

There was no statistically significant difference in the efficacy of MSCs derived from amniotic membrane, adipose, umbilical cord and bone marrow in the treatment of diabetic skin ulcers during the short-term observation period, and the probability ranking graphs indicate that amniotic membrane-derived MSCs may be the best choice for the treatment of diabetic skin ulcers.

The impact of cognitive behavioural therapy‐based psychological intervention on emotional improvement in elderly patients with extensive burns

Abstract

To evaluate the efficacy of cognitive behavioural therapy (CBT) as a psychological intervention for elderly patients with extensive burns, focusing on its impact on emotional well-being, self-efficacy and quality of life. A prospective, randomized study involving 200 elderly burn patients was conducted from November 2021 to January 2023. The patients were randomly assigned to receive either standard care (control group) or burn care based on cognitive behavioural therapy (CBT-B) (study group), with 100 patients in each group. Outcome measures included the Visual Analog Scale (VAS) for pain assessment, 36-item Short Form Survey (SF-36) for quality of life, General Self-Efficacy Scale (GSES) and Rosenberg Self-Esteem Scale (RSES). The study revealed that CBT-based intervention significantly reduced anxiety and depression scores compared with standard care (p < 0.05). Additionally, patients in the CBT group exhibited improved self-efficacy, self-esteem and quality of life (p < 0.05). CBT proves to be a valuable intervention for elderly burn patients, effectively addressing emotional distress and enhancing their psychological well-being. By modifying negative cognitive patterns, providing coping mechanisms and fostering problem-solving skills, CBT-based care contributes to a more positive recovery experience and improved quality of life.

Studying the effects of stress, mental health and psychological well‐being on wound healing rates after oesophageal varices ligation in liver cirrhosis patients

Abstract

It is of utmost importance to comprehend the impact that psychological factors have on physical rehabilitation, specifically in regards to wound healing following ligation of oesophageal varices in patients with liver cirrhosis. The present study investigated the correlation between wound recovery rates and psychological well-being, stress and mental health. From January 2022 to September 2023, 148 patients from were evaluated as part of this cross-sectional observational study. The psychological well-being of participants was evaluated utilizing the Hospital Anxiety and Depression Scale (HADS), Perceived Stress Scale (PSS) and Psychological General Well-Being Index (PGWBI). The rates of wound recovery were assessed following ligation. The mean duration for wound recovery was 28.37 ± 9.65 days. The mean wounds healing time of patients who obtained higher PSS scores (18.55) was marginally longer. On the contrary, there was a moderate reduction in healing time associated with higher HADS scores (mean 14.10). On average (68.88), PGWBI scores indicated a negligible effect on wound healing. The variance in healing durations between Child-Pugh classifications A, B and C (mean values of 28.65, 26.90 and 29.57 days respectively) suggested that the severity of liver disease has an impact. As a result of ligation of oesophageal varices, the study demonstrated that psychological factors and wound recovery in patients with liver cirrhosis are intricately intertwined. There seems to be the substantial and intricate relationship between stress, mental health and wound recovery. The results of this study supported the notion that psychological evaluation and support should be incorporated into the management of patients with liver cirrhosis.

Effects of rapid rehabilitation nursing on surgical‐site wound infection and postoperative complications of patients undergoing thoracoscopic lung cancer surgery: A meta‐analysis

Abstract

This meta-analysis systematically evaluates the impact of rapid rehabilitation nursing interventions on wound infections and postoperative complications in patients undergoing thoracoscopic lung cancer surgery. A comprehensive literature search was conducted, from database inception to November 2023, using databases including PubMed, Embase, Google Scholar, Cochrane Library, China National Knowledge Infrastructure, and Wanfang databases to identify randomized controlled trials (RCTs) that focused on the application of rapid rehabilitation nursing in the perioperative period of thoracoscopic lung cancer surgery. Two researchers independently screened the literature, extracted data, and assessed the quality based on inclusion and exclusion criteria. Data analysis was performed using Stata 17.0 software. A total of 22 RCTs involving 2319 patients were included in the analysis. The results indicated that the application of rapid rehabilitation nursing in thoracoscopic lung cancer surgery significantly reduced the incidence of wound infections (OR = 0.32, 95% CI: 0.20–0.54, p < 0.001) and postoperative complications (OR = 0.24, 95% CI: 0.18–0.31, p < 0.001). This study demonstrates that implementing rapid rehabilitation nursing interventions during the perioperative period for patients undergoing thoracoscopic lung cancer surgery can significantly decrease the occurrence of wound infections and complications, thereby facilitating rapid patient recovery.

A meta‐analysis of clinical studies of moxibustion for pressure ulcer healing

Abstract

In this study, we aimed to evaluate the effect of moxibustion on pressure ulcers. A thorough search was performed for articles published from database inception up to 14 December 2023. Randomized controlled trials, which evaluated the effects of moxibustion were included. Finally, 11 relevant trails that enrolled a total of 795 participants met inclusion criteria. The results of meta-analysis suggested beneficial effects of moxibustion for pressure ulcer compared with control on the response rate (RR: 1.21; 95% CI: 1.13–1.29; p = 0.82; I 2 = 0%), healing time (MD: −5.69; 95% CI: −9.58 to −1.80; p<0.05; I 2 = 97%) and pressure ulcer scale for healing scores (MD: −1.13; 95% CI: −1.36 to −0.89; p = 0.79; I 2 = 0%). The evidence suggests that moxibustion possesses satisfactory efficacy in promoting healing of pressure ulcers. However, due to the small number of trials included in this study, as well as the small sample size and high risk of bias, we were unable to draw firm conclusions about the effectiveness of moxibustion for pressure ulcers.

Etiological characteristics of wound infection in severe trauma patients and logistic regression analysis of influencing factors of infection

Abstract

To investigate the etiological characteristics of wound infection in severe trauma patients and logistic regression analysis of the influencing factors of infection. The 116 patients with severe trauma who were intervened in our hospital from 22 October 2017 to 9 September 2019 were selected as the subjects of this retrospective study and divided into a control group and an observation group according to whether they were infected or not, 58 cases each. Observe and compare the pathogenic characteristics (pathogen distribution and drug resistance) of the two groups of patients and logistic regression analysis of the influencing factors of infection. The gram-positive bacteria in the observation group were mainly Staphylococcus aureus, accounting for 17.20%; the fungi were mainly Candida tropicalis, accounting for 17.20%; and the gram-negative bacteria were mainly Acinetobacter baumannii, accounting for 20.39%; the control group was gram-positive. The main bacteria are S. aureus, accounting for 8.60%; the fungi are mainly Candida albicans, accounting for 4.3%; and the gram-negative bacteria, which are mainly Pseudomonas aeruginosa, accounting for 14.56%. Gram-positive bacteria Enterococcus faecium, S. aureus, Enterococcus faecalis, Staphylococcus epidermidis. The highest drug resistance of other gram-positive bacteria is penicillin and erythromycin at 85.00% and above. Fungi C. tropicalis, Candida parapsilosis, C. albicans, fluconazole and amphotericin B have the highest resistance to 80.00% and above. Gram-negative bacteria A. baumannii, Ps. aeruginosa, Klebsiella pneumoniae, Escherichia coli, Proteus mirabilis, Enterobacter cloacae and other gram-negative bacteria are the most resistant to ampicillin, and Piperacillin was 70.00% and above. The combined primary diseases of the two groups of patients, ventilator use ≧3 days, long-term use of glucocorticoids, catheter use days ≧5 days, fever days ≧3 days and long-term use of broad-spectrum antimicrobial drugs, the difference is statistically significant academic significance (p < 0.05). Logistic analysis showed that combined with underlying diseases, fever days ≥3 days, long-term use of glucocorticoids and catheter use days ≥5 days are the influencing factors for the occurrence of wound infections in patients with severe trauma. Trauma patients are prone to wound infections, and there are many influencing factors. Close observation of patients should be strengthened. Effective prevention and control measures should be taken for related influencing factors to reduce the incidence of infection.

Effect of bone grafting on postoperative wound infection and marginal necrosis in patients with calcane fractures

Abstract

This study was conducted to evaluate the impact of bone-transplantation over nonbone transplantation in treating intra-articular fractures of the heel bone on postsurgical complications. Our results were retrieved from the Pubmed, Embase, and Cochrane databases. The data of the injury of the patient and the wound infection were collected. Study were carried out with Revman 5.3 software. Eight operative trials associated with the implant of the heel were selected from a large number of publications. Among the 804 cases that needed operation on the heel, 410 cases were treated with bone grafting while 394 cases were not treated with the operation. Seven trials showed that there was no difference in the risk of post operative wound infection among patients who had received a bone-grafting operation on the heel or had not (OR, 0.87; 95% CI, 0.51, 1.49 p = 0.62). There was no difference in the risk for post-operation marginal necrosis among patients who had received a bone-grafting operation on the heel or had not (OR, 0.75; 95% CI, 0.42, 1.36 p = 0.34). The results of this show that there are no statistically significant differences in the incidence of post-operative necrosis and infection in the case of endarticular surgery of the heel.

The effect of placing prophylactic abdominal drainage tube after hepatobiliary surgery on postoperative infection: A systematic review and meta‐analysis

Abstract

Whether prophylactic abdominal drainage tube is routinely placed in patients after hepatobiliary surgery remains controversial. To evaluate the effect of prophylactic abdominal drainage tube placement after hepatobiliary surgery on postoperative infection. Randomized controlled trials on the placement of prophylactic abdominal drainage tube after hepatobiliary surgery were collected through a computerized search of PubMed, Embase, Conchrane Library and Web of Science databases, with a time range from the establishment of the database to August 2023. After two researchers independently screened the literature, extracted information, and evaluated the quality of the included studies. Finally, 13 studies were included, including 3620 patients, and the results showed that there was no statistically significant difference in postoperative infection rate between the drainage group (1840 patients and the non-drainage group [1783 patients] [relative risk, RR = 1.17, 95% confidence interval, CI: 0.94–1.47, p = 0.16]. Compared with the drainage group, the incidence of infectious abdominal fluid in the non-drainage group was lower (RR = 2.09, 95% CI: 1.57–2.80, p < 0.00001), and the incidence of postoperative bile leakage was lower (RR = 1.77, 95% CI: 1.27–2.47, p < 0.001) and shorter hospital stays after surgery (mean difference = 1.27, 95% CI: 0.32–2.22, p = 0.009). In conclusion, placing a prophylactic abdominal drainage tube after hepatobiliary surgery does not reduce postoperative infection rates compared with no drainage.

The impact of different antibiotic injection regimens on patients with severe infections: A meta‐analysis

Abstract

Severe infection is a critical health threat to humans, and antibiotic treatment is one of the main therapeutic approaches. Nevertheless, the efficacy of various antibiotic injection regimens in severe infection patients remains uncertain. This study aimed to comprehensively evaluate the impact of various antibiotic injection strategies on patients with severe infection through a meta-analysis. Relevant research literature was collected by searching databases such as PubMed, Embase, and Cochrane Library. The retrieved literature was screened according to inclusion and exclusion criteria. Relevant data, including study design, sample size, and antibiotic regimens, were extracted from the included studies. The Cochrane Collaboration's Risk of Bias tool was employed to assess the risk of bias in each study. Statistical analysis was performed based on the results of the included studies. A total of 15 articles were included, covering various types of severe infection patients, including pulmonary and abdominal infections. The analysis provided insights into mortality rates, treatment efficacy, adverse reactions (ARs), Acute Physiology and Chronic Health Evaluation (APACHE) scores, among other outcomes. The results indicated that combination therapy was superior to monotherapy in terms of mortality rate, treatment efficacy, and APACHE scores, while the incidence of ARs was lower in the monotherapy group compared to the combination therapy group (p < 0.05). Combination therapy showed better treatment efficacy compared to monotherapy, although it was associated with a higher incidence of ARs.

Fabrication of Cu/ZnO‐loaded chitosan hydrogel for an effective wound dressing material to advanced wound care and healing efficiency after caesarean section surgery

Abstract

Wound infections and delayed complications after caesarean section surgical procedure to mothers would have a prevalence of discomfort, stress and dissatisfaction in the postpartum period. In this report, one-pot synthesis is used for the preparation of chitosan (CS)-based copper nanoparticles (nCu), which was used for the preparation of zinc oxide (ZnO) hydrogel as wound dressing materials after surgery. The antibacterial activity of (CS-nCu/ZnO) developed hydrogels was studied zone of inhibition, against gram-positive and gram-negative bacteria. The antibacterial activity of the CS-nCu/ZnO hydrogel demonstrated that nanoformulated hydrogel materials have provided excellent bactericidal action against clinically approved bacterial pathogens. The biocompatibility and in vitro wound healing potential of the developed wound closure materials were studied by MTT assay and wound scratch assay methods, respectively. The MTT assay and cell migration assay results demonstrated that CS-nCu/ZnO hydrogel material induces cell compatibility and effective cell proliferation ability. These findings suggest that the CS-nCu/ZnO hydrogel outperforms CS-ZnO in terms of wound healing and could be used as a wound closure material in caesarean section wound treatment.

Success of transmetatarsal amputation for limb salvage in patients with peripheral artery disease

Abstract

Limb salvage is a difficult path for patients to travel as there is no guarantee of the outcome, often the major factor is perfusion. For patients who underwent transmetatarsal amputation (TMA), success rate is crucial as the next option is most likely a major amputation. We performed a 10 years (2010–2020) retrospective review of patients that underwent a TMA and had an angiogram or computed tomography angiography (CTA) perioperatively at the Dallas VA Medical Center. Failure after TMA was defined as a patient requiring a proximal amputation within 1 year. There were 125 TMAs performed between 2010 and 2020 at the institution. Forty-four (35.2%) patients had an angiogram/CTA peri-operative and met the inclusion criteria. Seventeen subjects (38.6%) had a higher level of amputation. Of the 17 failures, 2 (11.8%) patients had no patent vessel runoff to the foot, 9 (52.9%) had one vessel, 4 (23.5%) had two vessels, and 2 (11.8%) had three vessels runoff. One vessel runoff to the foot yielded a high rate of poor outcomes (56.3%) defined as a higher level of amputation. Two or more vessels runoff to the foot had over 75% success of limb salvage with a TMA.

Effect of accelerated rehabilitation nursing programmes on surgical site wound infection in patients undergoing laparoscopic cholecystectomy: A meta‐analysis

Abstract

This study aims to evaluate the effect of an accelerated rehabilitation nursing programme on the incidence of surgical site wound infections in patients undergoing laparoscopic cholecystectomy. Relevant studies regarding the use of an accelerated rehabilitation nursing programme in laparoscopic cholecystectomy were retrieved from databases, including PubMed, Web of Science, the Cochrane Library, EMBASE, CNKI and Wanfang Database. The search was conducted from the inception of each database until June 2023. Two independent researchers performed the literature screening, data collection and quality assessment of the included studies. Odds ratio (OR) and 95% confidence interval (CI) were used as the measures of effect. Statistical analysis was conducted using Stata 17.0, and a sensitivity analysis and publication bias evaluation were performed. A total of 21 studies involving 2480 patients (1179 in the intervention group and 1301 in the control group) were included. The meta-analysis revealed that the incidence of surgical site wound infections in the intervention group was significantly lower than in the control group (1.18% vs. 5.99%, OR: 0.322, 95% CI: 0.168–0.556, p < 0.001). Current evidence suggests that implementing accelerated rehabilitation nursing programmes for patients undergoing laparoscopic cholecystectomy has a clinically significant effect, leading to a substantial reduction in the incidence of surgical site wound infections. However, owing to the low quality of some of the included studies, further high-quality, multicentre, large-sample randomised controlled trials are required to validate the conclusions of this study.

Utility of dexmedetomidine on surgical site wound pain undergoing thoracoscopic surgery: A meta‐analysis

Abstract

We conducted this study aimed to evaluate the analgesic effect of dexmedetomidine in thoracoscopic surgery on postoperative wound pain, and to provide a reference for clinical use of the drug. We searched PubMed, Embase, Cochrane Library, Web of Science, Wanfang, Chinese Biomedical Literature Database and China National Knowledge Infrastructure databases, and supplemented with manual searching. We searched from database inception to October 2023, to collect the randomised controlled trials (RCTs) on dexmedetomidine application in thoracoscopic surgery. Two researchers screened all the literature according to the inclusion and exclusion criteria and the literature included in the study was evaluated for quality, extracted information and required data. Stata 17.0 software was employed for data analysis and the outcomes were 2 6, 12, 24 and 48 h postoperative wound visual analog scores (VAS). Twenty-four RCTs totalling 2246 patients undergoing thoracoscopic surgery were finally included. The analysis revealed dexmedetomidine applied to thoracoscopic surgery significantly reduced the postoperative wound VAS scores at 2 h (SMD: −0.96, 95% CI: −1.57 to −0.36, p = 0.002), 6 h (SMD: −0.98, 95% CI: −1.27 to −0.69, p < 0.001), 12 h (SMD: −1.19, 95% CI: −1.44 to −0.94, p < 0.001), 24 h (SMD: −0.91, 95% CI: −1.16 to −0.66, p < 0.001) and 48 h (SMD: −0.75, 95% CI: −1.02 to −0.48, p < 0.001). Our results suggest dexmedetomidine applied to thoracoscopic surgery can significantly reduce postoperative wound pain, which is worthy of clinical application.

Predictors for different types of surgical site infection in patients with gastric cancer: A systematic review and meta‐analysis

Abstract

Various factors contribute to different types of surgical site infections (SSI) in gastric cancer patients undergoing surgery, and the risk factors remain uncertain. This meta-analysis aims to clarify the relationship between various factors and SSI, resolving existing controversies. Thirty-four eligible articles with 66 066 patients were included in the meta-analysis. Significant risk factors for SSI included age ≥65 years, male gender, BMI ≥25 kg/m2, diabetes, hypertension, advanced TNM stage ≥III, pathologic T stage ≥T3, pathologic N stage ≥N1, ASA ≥3, open surgery, blood transfusion, extensive resection, combined resection, splenectomy, D2 or more lymph node dissection, and operative time ≥240 min. Operative time showed a nonlinear relationship with SSI risk. Subgroup analysis revealed significant differences in the effects of risk factors among different infection types. These findings inform the development of targeted preventive measures to reduce SSI rates.

The effect of dexmedetomidine on postoperative wound healing in neurosurgical patients: A meta‐analysis

Abstract

This meta-analysis investigates the effect of dexmedetomidine on postoperative wound healing in neurosurgical patients. A thorough literature search resulted in the selection of seven studies from an initial pool of 1546 records. The analysis focused on wound healing outcomes, evaluated by the Redness, Oedema, Ecchymosis, Discharge, Approximation (REEDA) scale and the Manchester Scar Scale (MSS). Results indicated significant improvements in the dexmedetomidine group: the REEDA scale scores at day seven post-surgery showed a Standardized Mean Difference group (SMD = −16.18, 95% CI: [−22.30, −10.06], p < 0.01), and the MSS scores at 3 months post-operation demonstrated an (SMD = −8.95, 95% CI: [−14.27, −3.62], p < 0.01). These findings suggest that dexmedetomidine may enhance wound healing and reduce scar formation in neurosurgical patients. Bias assessment indicated a low risk of bias across the studies.

PCAT‐1′ s role in wound healing impairment: Mitochondrial dysfunction and bone marrow stem cell differentiation inhibition via PKM2/β‐catenin pathway and its impact on implant osseo‐integration

Abstract

This study focused on unravelling the role of PCAT-1 in wound-healing process, particularly its impact on regenerative and osteogenic abilities of mesenchymal stem cells (MSCs). We delved into how PCAT-1 regulates mitochondrial oxidative phosphorylation (OXPHOS) and interacts with pivotal molecular pathways, especially β-catenin and PKM2, using human bone marrow-derived MSCs. MSCs were cultured under specific conditions and PCAT-1 expression was modified through transfection. We thoroughly assessed several critical parameters: MSC proliferation, mitochondrial functionality, ATP production and expression of wound healing and osteogenic differentiation markers. Further, we evaluated alkaline phosphatase (ALP) activity and mineral deposition, essential for bone healing. Our findings revealed that overexpressing PCAT-1 significantly reduced MSC proliferation, hampered mitochondrial performance and lowered ATP levels, suggesting the clear inhibitory effect of PCAT-1 on these vital wound-healing processes. Additionally, PCAT-1 overexpression notably decreased ALP activity and calcium accumulation in MSCs, crucial for effective bone regeneration. This overexpression also led to the reduction in osteogenic marker expression, indicating suppression of osteogenic differentiation, essential in wound-healing scenarios. Moreover, our study uncovered a direct interaction between PCAT-1 and the PKM2/β-catenin pathway, where PCAT-1 overexpression intensified PKM2 activity while inhibiting β-catenin, thereby adversely affecting osteogenesis. This research thus highlights PCAT-1's significant role in impairing wound healing, offering insights into the molecular mechanisms that may guide future therapeutic strategies for enhancing wound repair and bone regeneration.

Visualizing the global trends of peptides in wound healing through an in‐depth bibliometric analysis

Abstract

Wound healing is a complicated and multistage biological process for the repair of damaged/injured tissues, which requires intelligent designs to provide comprehensive and convenient treatment. Peptide-based wound dressings have received extensive attention for further development and application due to their excellent biocompatibility and multifunctionality. However, the current lack of intuitive analysis of the development trend and research hotspots of peptides applied in wound healing, as well as detailed elaboration of possible research hotspots, restricted obtaining a comprehensive understanding and development in this field. The present study analysed publications from the Web of Science (WOS) Core Collection database and visualized the hotspots and current trends of peptide research in wound healing. Data between January 1st, 2003, and December 31st, 2022, were collected and subjected to a bibliometric analysis. The countries, institutions, co-authorship, co-citation reference, and co-occurrence of keywords in this subject were examined using VOSviewer and CiteSpace. We provided an intuitive, timely, and logical overview of the development prospects and challenges of peptide application in wound healing and some solutions to the major obstacles, which will help researchers gain insights into the investigation of this promising field.

Impact of preoperative chemotherapy on cutaneous wound healing in lung cancer patients: A meta‐analysis

Abstract

As part of their treatment, lung cancer patients frequently endure thoracic oncological surgery, with preoperative chemotherapeutic interventions being the common approach. However, the potential impact of these chemotherapeutic regimens on cutaneous wound healing outcomes following surgery remains the topic of considerable clinical interest. This meta-analysis sought to evaluate comprehensively the effect of preoperative chemotherapeutic regimens on cutaneous wound healing in lung cancer patients following thoracic oncological surgery. Extensive literature searches were conducted using the leading databases PubMed, Embase, Cochrane Library and Scopus. Eight studies out of 1342 identified satisfied the inclusion criteria. Consideration was given to both randomized controlled trials (RCTs) and observational studies. Data pertaining to study characteristics, patient demographics, chemotherapeutic regimens and wound healing outcomes were extracted with great attention to detail. The examination of these varied studies provided insights into the fluctuations in rates of recovery following treatment, incidences of wound infections and frequencies of surgical complications. The research studies provided odds ratios for recovery that varied significantly in magnitude from 0.95 to 0.38, with regard to the probability of wound infection. Furthermore, a range of odds ratios for complications were disclosed, with certain odds ratios displaying narrow confidence intervals. The complexity of the effect of preoperative chemotherapy on wound closure subsequent to thoracic oncologic surgery is highlighted by our findings. The results underscore the need for individualized treatment strategies for lung cancer patients undergoing surgical procedures that strike a balance between patient safety and optimal clinical outcomes.
