All identified articles were reviewed by two reviewers against the eligibility criteria. The risk of bias was assessed using the Mixed Methods Appraisal Tool and the Joanna Briggs Institute critical appraisal tool. Data were narratively synthesised due to methodological heterogeneity. Twenty-two studies (12 quantitative; 9 qualitative;1 mixed methods) met the inclusion criteria. The qualitative studies were grouped into four impact areas: symptoms, physical function, psychological well-being and social functioning. Five instruments were used to assess HRQoL and identified low scores in people with PIs, with the lowest scores mostly reported in physical functioning and role physical and emotional concepts. A complexity of factors influenced theHRQoL of people with PI. This review synthesised both quantitative and qualitative evidence indicating PI was associated with low HRQoL scores and negatively affected all aspects of HRQoL. This review emphasised the complexity of factors related to PI and its impact on HRQoL. Further emphasis on the impact of the complexity of factors on HRQoL of people with PI should be considered in future studies.</p>","PeriodicalId":23864,"journal":{"name":"Wound Repair and Regeneration","volume":" ","pages":"e13236"},"PeriodicalIF":3.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142693436","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}

Chronic diabetic ulcers do not follow an orderly progression through the wound healing process and are associated with a persistent inflammatory state characterised by the accumulation of pro-inflammatory macrophages, cytokines and proteases. Photobiomodulation has been successfully utilised in diabetic wound healing and involves illuminating wounds at specific wavelengths using predominantly light-emitting diodes or lasers. Photobiomodulation induces wound healing through diminishing inflammation and oxidative stress, among others.

However, its effects in the fields of regenerative medicine and tissue engineering are still under investigation. Studying PBM effects on the regenerative capacity of zebrafish can allow the application of novel clinical approaches where the impact of PBM will be cross-linked with the stem-cell therapeutic approaches. This study was done to establish an in-vivo experimental setup for studying the effects of laser and ultraviolet therapy on zebrafish caudal-fin regeneration and vascularization. Thirty zebrafish were randomly and equally allocated into three groups. The caudal-fins of all zebrafish were amputated under anaesthesia. In the first control group, the caudal-fin was only monitored until fully regenerated. In the second group, the amputated-fin was irradiated with ultraviolet. Finally, in the third group, the amputated-fin was irradiated with laser. Caudal-fin regeneration and vascularization were assessed at days 0, 3, 6, 9, 12, and 15 in all fish. In terms of regeneration, the results indicated that it is possible to discriminate the regenerative effect of laser with the experimental setup as laser therapy showed a statistically significant difference when compared to control-group. It was also found that regenerative stimulation of the group that received ultraviolet therapy showed significant difference when compared to the control group. In terms of vascularization, there was a statistically significant difference in all groups of the study, which may suggest that laser as well as ultraviolet have limited effects in terms of improving vascularization. This study presented a novel, simple and inexpensive method for the assessment of PBM effects on zebrafish. Laser and ultraviolet therapy appeared to act as regenerative stimulators for caudal-fin regeneration of zebrafish. However, laser therapy results were, to some extent, better than ultraviolet therapy. This novel in-vivo design of the experiment led to more rapid and reproducible results than in-vitro experiments.</p>","PeriodicalId":23864,"journal":{"name":"Wound Repair and Regeneration","volume":" ","pages":"e13234"},"PeriodicalIF":3.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11628771/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142645050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the 1980s, we have learned much about the role of biofilm in human chronic infections, with associated global healthcare costs recently estimated at ~$386 billion. Chronic wound infection is a prominent biofilm-induced condition that is characterised by persistent inflammation and associated host tissue destruction, and clinical signs that are distinct from signs of acute wound infection. Biofilm also enables greater tolerance to antimicrobial agents in chronic wound infections compared with acute wound infections. Given the difficulty in eliminating wound biofilm, a multi-targeted strategy (namely biofilm-based wound care) involving debridement and antimicrobial therapies were introduced and have been practiced since the early 2000s. More recently, acknowledgement of the speed at which biofilm can develop and hence quickly interfere with wound healing has highlighted the need for an early anti-biofilm strategy to combat biofilm before it takes control and prevents wound healing. This strategy, referred to as wound hygiene, involves multiple tools in combination (debridement, cleansing, and antimicrobial dressings) to maximise success in biofilm removal and encourage wound healing. This review is intended to highlight the issues and challenges associated with biofilm-induced chronic infections, and specifically address the challenges in chronic wound management, and tools required to combat biofilm and encourage wound healing.</p>","PeriodicalId":23864,"journal":{"name":"Wound Repair and Regeneration","volume":" ","pages":"e13241"},"PeriodicalIF":3.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142733119","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}

Axolotl (Ambystoma mexicanum) is a critically endangered salamander species and a model organism for regenerative and developmental biology. Despite its significance, a noticeable gap exists in understanding the interplay between axolotl regeneration and its microbiome. Here, we analyse in depth bacterial 16S rRNA amplicon dataset that we reported before as data resource and profile fungal community by sequencing ITS amplicons at the critical stages of limb regeneration (0-1-4-7-30-60 days post amputation, 'dpa'). Results reveal a decline in richness and evenness in the course of limb regeneration, with bacterial community richness recovering beyond 30 dpa unlike fungi community. Beta diversity analysis reveals precise restructuring of the bacterial community along the three phases of limb regeneration, contrasting with less congruent changes in the fungal community. Temporal dynamics of the bacterial community highlight prevalent anaerobic bacteria in initiation phase and Flavobacterium bloom in the early phase correlating with limb blastema proliferation. Predicted functional analysis mirrors these shifts, emphasising a transition from amino acid metabolism to lipid metabolism control.

High extracellular matrix binding ability of VLU isolates was associated with antimicrobial resistance and expression levels of the embp and sdrG, responsible for bacterial binding to fibrinogen and fibrin, respectively.

However, whether BACC can modulate the phenotype of dysregulated macrophages, like those present in burn wounds, is not known. To better understand the macrophage modulatory characteristics of the BACC, primary human macrophages were polarised to the M2b phenotype, an immunosuppressive phenotype relevant to burn wounds, by simultaneously exposing macrophages to polystyrene plate-coated immunoglobulin G and the endotoxin lipopolysaccharide (LPS). The resulting macrophage phenotype upregulated both inflammatory and reparative genes, and increased secretion of the M2b marker CCL1 compared to five different in vitro macrophage phenotypes. M2b macrophages were cultured with the BACC in the presence or absence of LPS to mimic infection, which is a common occurrence in burn wounds. The BACC caused up-regulation of reparative gene sets and down-regulation of pro-inflammatory gene sets, even when LPS was present in the cell culture media. Co-cultures were maintained for 1, 3, or 5 days in the presence of LPS, and by day 1 both non-activated macrophages and M2b macrophages exhibited signs of endotoxin tolerance, as demonstrated by a reduced secretion of tumour necrosis factor α (TNFα) in response to fresh LPS stimulus. The BACC was not able to prevent endotoxin tolerance, but reparative genes were upregulated in macrophages chronically exposed to LPS. These results suggest that the BACC can promote a reparative phenotype in dysregulated macrophages relevant to the pathophysiology of burns.</p>","PeriodicalId":23864,"journal":{"name":"Wound Repair and Regeneration","volume":" ","pages":"992-1007"},"PeriodicalIF":3.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142366749","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}

Our research revealed a significant prevalence of vitamin deficiencies among the participants, and we observed a noteworthy correlation between amputation rates and these deficiencies.
