This study employs rheological analysis to characterise exudates viscosity, comparing cattle-derived samples to the test solution A. Results reveal non-Newtonian, shear-thinning behaviour in exudates, contrasting with the Newtonian behaviour of the test solution A.

This retrospective cohort study aimed to refine the relevant clinical evidence and investigate the effect of chemotherapy on pathological scars in children. In this single-centre retrospective cohort study, the data of children aged ≤18 years who underwent thoracic surgery at the Children's Hospital of Fudan University between 1 January 2018, and 31 December 2021 were assessed. The primary outcome was pathological scarring, and the secondary outcomes were subjective symptoms accompanying pathological scarring, such as pain and itching. To mitigate indication bias, analysis was performed by inverse probability weighting (IPTW) log-binomial regression models. The cohort comprised 102 children, among whom 36 received adjuvant chemotherapy perioperatively, while 66 did not. Under the IPTW model, a statistically significant difference in pathological scarring incidence was observed between the chemotherapy and non-chemotherapy groups (16.7% vs. 29.4%, p = 0.027). And the children received chemotherapy post-operatively had a lower relative risk of pathological scarring, compared with those received chemotherapy both before and after surgery (19.8% vs. 28.8%).

Current therapies for full-thickness injuries that target specific phases of wound healing have moderate success; however, full resolution remains incomplete and negative consequences persist if skin homeostasis is not achieved. Photoactivated molecules can modulate cellular responses by generating reactive oxygen species and may provide a novel therapeutic option to improve wound healing. In the current study, we investigated the effects of Rose bengal (RB) dye in a preclinical model of full-thickness cutaneous injury. Monochromatic green light activates RB to generate ROS in the presence of oxygen, subsequently crosslinking collagen fibrils. In in vitro studies, we show that photoactivated RB is well tolerated by epidermal keratinocytes and dermal fibroblasts and can mitigate fibrotic signalling by downregulating collagen production. In a murine model of full-thickness injury, topically-applied and photoactivated RB closed wounds faster than control and vehicle treatments and showed significantly improved wound healing outcomes, including enhanced early granulation, better collagen organisation and increased vascularity in the presence of protracted tissue ROS. These data support an overall improved cutaneous wound healing profile after RB phototherapy and warrant further investigations into this versatile molecule.</p>","PeriodicalId":23864,"journal":{"name":"Wound Repair and Regeneration","volume":" ","pages":"758-769"},"PeriodicalIF":3.8,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141898384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This cross-sectional study used the Japanese Nationwide Survey on Foot Ulcer Management dataset, consisting of 249 medical doctors and 680 allied health professionals. The types of health professionals involved in the diabetic foot were identified, and the tasks performed by each professional were compared within subgroups (medical doctors and allied health professionals). We found that the primary medical doctors involved in diabetic foot care in Japan were plastic surgeons (33.5%), dermatologists (21%), cardiovascular/vascular surgeons (15.2%), and cardiologists (12.1%). Nurses were the main allied health professionals (80%), and the rest consisted of prosthetists/orthotists (7.6%), physical/occupational therapists (5.9%), and clinical engineering technologists (3.6%). Medical doctors performed tasks related to their specialties significantly more than others (p < 0.001); however, they also engaged in tasks outside of their specialty, such as plastic surgeons performing preventive foot care (72%). Among allied health professionals, clinical engineering technologists performed more vascular assessments (p < 0.001), and half were engaged in wound management, preventive foot care, and self-foot care education. In conclusion, the type and proportion of health professionals in our study differed from those in countries with podiatrists, and many performed tasks outside their specialties.

A search was conducted on 21 August 2023, by the first and second authors independently from 1985 to August 2023 using PubMed, MEDLINE, Embase, Web of Science, Scopus and CINAHL. The following MeSH terms were used: 'Keloid', 'Risk' and 'Genetic'. Two researchers independently searched for studies based on titles and abstracts and screened filtered articles by reviewing full text. If no agreement could be reached, a third senior author designated whether the article should be included. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement as the basis of our organisation. Human studies with genetic analysis to determine an association of a protein or gene to keloidogenesis were selected for inclusion. Studies in languages other than English, reviews, conference articles, and book chapters were excluded. Fifty studies met inclusion criteria. The human leukocyte antigen (HLA) system was broadly implicated, and the DRB1*15 allele was associated with an increased risk of keloid in three separate ethnic groups. Some HLA Class I alleles were associated with keloid in one population but not in others. Additionally, polymorphisms in the E3 ubiquitin-protein ligase (NEDD4) signal cascade and vitamin D receptor (VDR) have been implicated in diverse groups.
