Metabolism, fibrosis, and apoptosis: The effect of lipids and their derivatives on keloid formation

Abstract

Keloids, pathological scars resulting from skin trauma, have traditionally posed significant clinical management challenges due to their persistence and high recurrence rates. Our research elucidates the pivotal roles of lipids and their derivatives in keloid development, driven by underlying mechanisms of abnormal cell proliferation, apoptosis, and extracellular matrix deposition. Key findings suggest that abnormalities in arachidonic acid (AA) synthesis and non-essential fatty acid synthesis are integral to keloid formation. Further, a complex interplay exists between lipid derivatives, notably butyric acid (BA), prostaglandin E2 (PGE2), prostaglandin D2 (PGD2), and the regulation of hyperfibrosis. Additionally, combinations of docosahexaenoic acid (DHA) with BA and 15-deoxy-Δ12,14-Prostaglandin J2 have exhibited pronounced cytotoxic effects. Among sphingolipids, ceramide (Cer) displayed limited pro-apoptotic effects in keloid fibroblasts (KFBs), whereas sphingosine 1-phosphate (S1P) was found to promote keloid hyperfibrosis, with its analogue, FTY720, demonstrating contrasting benefits. Both Vitamin D and hexadecylphosphorylcholine (HePC) showed potential antifibrotic and antiproliferative properties, suggesting their utility in keloid management. While keloids remain a prevalent concern in clinical practice, this study underscores the promising potential of targeting specific lipid molecules for the advancement of keloid therapeutic strategies.

The effect of placing drains and no drains after caesarean section in obese patients on patients' post‐operative wound complications: A meta‐analysis

Abstract

The purpose of this research is to investigate the influence of placement of drainage channels and non-drainage channels in obese women on post-caesarean delivery. Documents were retrieved from four databases, such as PubMed and Embase. This study was not limited in time, language, or geography. This trial was conducted using either a cohort or a randomized, controlled study to compare the efficacy of placement of drain in caesarean delivery channel in obese women with or without drain for post-operative wound complications. The study excluded those who were restricted to those who were not overweight. The main results were the wound infection, the bleeding of the wound and the dehiscence. The risk of bias was evaluated by two authors with a risk-of-bias tool for nonrandomized intervention trials. The meta-analyses only included those that were considered to have a low-to-medium risk of bias. The data were pooled with a random-effects model to determine the relative risk and 95% confidence interval (CI). The quality of the evidence in the selection of results was evaluated. Of 329 related trials, eight were eligible for inclusion. There were 1868 cases of obesity who received C-section. Among them, there were 451 cases of drain and 1417 cases of non-drain. No statistical significance was found in the rate of post-operation infection of the post-operation between non-drain or drain treatment of obesity patients (OR, 0.8; 95% CI: 0.48–1.33; p = 0.39). Compared with those with non-drain, there was a reduction in the risk of haematoma after drain (OR, 0.34; 95% CI: 0.20–0.58; p < 0.0001). The results showed that there were no significant differences in the influence of drainage and non-drainage on the post-operative dehiscence of the patients with obesity (OR, 0.84; 95% CI: 0.15–4.70; p = 0.85). The results showed that there were no statistically different effects on the rate of post-operation wound infection and dehiscence after operation, but the rate of haematoma during drain operation was lower.

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.

Diabetic foot wound ulcers management by vacuum sealing drainage: A meta‐analysis

Abstract

The meta-analysis aimed to assess and compare diabetic foot wound ulcer management by vacuum sealing drainage. Using dichotomous or contentious random- or fixed-effects models, the outcomes of this meta-analysis were examined, and the odds ratio (OR) and the mean difference (MD) with 95% confidence intervals (CIs) were computed. Twenty-three examinations from 2000 to 2023 were enrolled for the present meta-analysis, including 1928 individuals with diabetic foot ulcers. Vacuum sealing drainage had significantly lower wound healing (OR, 2.35; 95% CI, 1.79–3.08, p < 0.001), lower duration of therapy (MD, −6.19; 95% CI, −10.06 to −2.32, p = 0.002), higher wound size reduction (MD, 4.22; 95% CI, 0.87–7.56, p = 0.01) and lower complication (OR, 0.32; 95% CI, 0.13–0.80, p = 0.01) compared with standard therapy in patients with diabetic foot ulcers. The examined data revealed that vacuum sealing drainage had significantly lower wound healing, duration of therapy and complication rates, as well as higher wound size reduction, compared with standard therapy in patients with diabetic foot ulcers. Yet, attention should be paid to its values since most of the selected examinations had a low sample size.

Comparative efficacy of silver alginate dressings versus standard gauze in enhancing wound healing post‐mastectomy for triple‐negative breast cancer: A systematic review and meta‐analysis

Abstract

This meta-analysis evaluates the efficacy of silver alginate dressings (SAD) compared to standard gauze (SG) in enhancing wound healing and reducing scar formation post-mastectomy in patients with triple-negative breast cancer. From an initial pool of 1245 articles, five studies met the inclusion criteria. The analysis revealed that SAD significantly improve early wound healing 1 week post-mastectomy, as indicated by lower Redness, Edema, Ecchymosis, Discharge, and Approximation (REEDA) scales (I 2 = 85%; Random: SMD: −7.08, 95% CI: −8.26 to −5.98, p < 0.01), compared to SG. Additionally, long-term scar outcomes measured by the Manchester Scar Scale (MSS) 5 months post-mastectomy showed a notable reduction in scar formation (I 2 = 95%; Random: SMD: −12.97, 95% CI: −16.20 to −9.75, p < 0.01)) in the silver alginate group. The findings support the use of SAD in post-mastectomy care for triple-negative breast cancer patients but highlight the need for further research on long-term safety and cost-effectiveness.

Previous studies showed that physical activity (PA) is concerned with hypertension (HTN). However, the mediation and interaction role of the obesity index: body mass index (BMI), waist-hip ratio (WHR), body fat rate (BFR) and visceral fat index (VFI) between PA and HTN has never been studied. Therefore, the purpose of this study was to assess the mediation and interaction of the obesity index between moderate-vigorous recreational physical activity (MVRPA) and HTN. We conducted a cross-sectional study of 4710 individuals aged 41 or older in Torch Development Zone, Zhongshan City. The mediation and interaction of the obesity index were evaluated by a four-way decomposition. 48.07% of participants had HTN among these groups. In the adjusted linear regression model, MVRPA was significantly correlated with WHR (β±SE = -0.005±0.002; POR) = 1.35), 95% (confidence interval (CI) = 1.17–1.56), insufficient MVRPA increased the risk of developing HTN. Furthermore, there were associations between BMI, WHR, BFR, VFI and HTN where the adjusted ORs and 95% CIs were 1.11 (1.09–1.13), 6.23 (2.61–14.90), 1.04 (1.03–1.06), 1.07 (1.06–1.09), respectively. The mediation analyses suggested that the impact of MVRPA on HTN risk may partly be explained by changes in obesity index, with a pure indirect mediation of WHR between MVRPA and HTN (P

Introduction

Stroke remains the second leading cause of death worldwide, a common cause of which is intracranial atherosclerotic stenosis (ICAS). Medical treatment is recommended as first-line therapy for treating ICAS, but the recurrence rate remains high. Drug-coated balloon (DCB) angioplasty has been designed to lower the risk of recurrent stenosis, holding therapeutic promise in the treatment of ICAS. However, the benefits of DCB require further evaluation.

Methods and analysis

The Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols was followed to develop this protocol. We will systematically search online databases including Cochrane Central Register of Controlled Trials, PubMed, Web of Science, EMBASE, China Biological Medicine Database, ClinicalTrials.gov and WHO ICTRP from 1 January 2011 to the date of search. This will be supplemented by a manual search of unpublished and ongoing trials to manually select articles for inclusion. Inclusion criteria are randomised or quasi-randomised clinical trials and observational studies that investigated DCB or medical treatment for patients with a symptomatic ICAS of 50%–99%. The primary outcome is short-term composite safety including death of any cause, or non-fatal stroke. Secondary outcomes include long-term death or stroke, restenosis, neurological rehabilitation, quality of life and other complications. The available data will be analysed using meta-analysis, if appropriate. The evaluation of heterogeneity and biases will be guided by the Cochrane Handbook for Systematic Reviews of Interventions.

Ethics and dissemination

This systematic review does not require ethical approval as all available data from eligible studies will be anonymous with no concerns regarding privacy. Our findings will be disseminated through international conferences and peer-reviewed publications. Additional data from the study are available on request to corresponding authors via email.

Effects of an enhanced recovery after surgery nursing programme on surgical site wound infection and postoperative complications in patients undergoing total knee arthroplasty: A meta‐analysis

Abstract

This meta-analysis aimed to investigate the effects of the enhanced recovery after surgery (ERAS) nursing program on surgical wound infection (SWI) and postoperative complications in patients undergoing total knee arthroplasty (TKA). The PubMed, Web of Science, Cochrane Library, Embase, China National Knowledge Infrastructure and Wanfang databases were searched from the date of establishment of the database until August 2023 for randomised controlled trials (RCTs) that assessed the effects of the ERAS nursing program on SWI and postoperative complications in patients undergoing TKA. The literature was screened, data were extracted by two independent investigators, and the literature quality was assessed using the methods recommended by the Cochrane Collaboration. Data analysis was performed using Stata 17.0 software. Nineteen RCTs with 1580 patients were included in the study. The meta-analysis results showed that the rates of SWI (odds ratio [OR] = 0.19, 95% confidence interval [CI]: 0.10–0.37, p < 0.001) and postoperative complications (OR = 0.18, 95% CI: 0.12–0.25, p < 0.001) were significantly lower in the ERAS intervention group than those in the control group. Therefore, ERAS intervention after TKA can significantly reduce the occurrence of SWI and postoperative complications. It has a remarkable rehabilitation effect and can be widely used in clinical settings.

Effect of enhanced recovery after surgery nursing on the incidence of surgical site wound infection in older adults with hip fractures: A meta‐analysis

Abstract

This meta-analysis evaluated the effect of enhanced recovery after surgery (ERAS) nursing on the incidence surgical site wound infection in older adults with hip fractures. The PubMed, Embase, the Cochrane Library, Web of Science, China Biomedical Literature Database, Wanfang, China National Knowledge Infrastructure, and VIP databases were searched from inception up to March 2023 for articles on randomized controlled trials (RCTs) on the effect of ERAS nursing on surgical site wound infection in older adults with hip fractures. Patients in the experimental group received ERAS nursing, and patients in the control group received conventional postoperative nursing. Two researchers independently completed literature screening and data extraction. The included articles were evaluated according to Cochrane quality assessment standards and the meta-analysis was conducted using Stata 17.0 software to calculate the effect sizes and their 95% confidence intervals (CIs). Twelve RCTs were included with 1117 patients, including 559 in the experimental group and 558 in the control group. In older adults with hip fractures, ERAS nursing reduced the risk of surgical site wound infection (odds ratio [OR]: 0.26, 95% CI: 0.11–0.58, p = 0.001) and postoperative complications (OR: 0.22, 95% CI: 0.14–0.33, p < 0.001), and reduced the length of hospital stay (mean difference: −4.04 days, 95% CI: −4.33 to −3.76 days, p < 0.001). In older adults with hip fractures, ERAS nursing reduces the incidence of surgical site infection and complications and shortens the length of hospital stay.
