Abstract Chronic wounds include, but are not limited to, radiation ulcers, pressure ulcers, vascular ulcers and diabetic foot ulcers. These chronic wounds can persist for years without healing and severe ulcers may lead to amputation. Unfortunately, the underlying pathologies of refractory chronic wounds are not fully characterized, and new treatments are urgently needed. Recently, increasing evidence has indicated that cell senescence plays an important role in the development of chronic wounds, and preventing cell senescence or removing senescent cells holds promise as a new therapeutic strategy. In this review, we aim to probe these latest findings to promote the understanding of cellular senescence in the pathological process and potential management of chronic wounds.

Objective: A chronic wound fails to progress through the phases of wound healing in an orderly and appropriate process, and poses a major challenge to wound care professionals. Pressure ulcers (PUs) and diabetic foot ulcers (DFUs) are classified as chronic wounds. Antiseptics, such as povidone-iodine (PVP-I), are often used to treat bacterial infections in chronic wounds; however, their efficacy and ability to accelerate wound healing has come into question. As a result, current medical research is now focusing on alternative and natural antiseptic agents, such as honey, for the treatment of chronic wounds. The aim of this study was to analyze the wound healing effects of honey in PU and DFU treatment in comparison to standard antiseptic care. Methods: A systematic literature search of PubMed, ScienceDirect, and ClinicalKey was conducted to identify all published data of clinical trials and narrative reviews that investigated or reported the use of honey and standard antiseptics in the treatment of PUs and DFUs in adults. A keyword search was then performed using the following keywords: “PUs”, “DFUs”, “antiseptics”, “PVP-I”, “honey”, “Manuka honey (MH)”, and “wound healing”. Database restrictions were implemented based on the inclusion and exclusion criteria, notably the report’s availability, completion status and language, the sample populations’ age, as well as, the date of publication. A preferred reporting item for systematic review and meta-analysis (preferred reporting items for systematic reviews and meta-analyzes) diagram was constructed illustrating the study selection process. The eligibility of articles was assessed by the screening of titles, abstracts and full texts. A total of 12 articles were included in this study comprising of 775 patients with PUs, DFUs or a combination of PUs and DFUs. Results: Results indicated that honey reduced bacterial infection, reduced pain and edema experienced by patients, reduced the odor of the wound and promoted wound healing in the treatment of chronic ulcers. Honey was also found to be effective in the process of debridement and exudate removal. Conclusion: Honey was found to be highly effective in the treatment of PUs and DFUs and should be considered as an alternative to standard antiseptic care in the treatment of chronic wounds. However, the literature in this study is limited and so further research into honey and its antiseptic-promoting activity in wound healing is recommended.

Background: Diabetic foot ulcers continue to pose significant global issue despite the advances made in the management of diabetes. It causes major foot complications if they are not addressed properly. It needs multidisciplinary approach for its care. While several advancements has taken place in wound care management, platelet rich plasma and stem cell therapy promises to offer a new hope in its management, aiding in cellular and tissue regeneration. The purpose of the present study was to compare Platelet-Rich Plasma versus conventional dressing in the management of diabetic foot ulcers.Methods: This prospective study was focused on 20 diabetic foot ulcers, carried out in a surgical unit of ACS Medical College and Hospital, Chennai, Tamil Nadu, from January 2018 to June 2018. Patients were divided into two groups; Group A received conventional ordinary dressing (N=10, 50%) and Group B received PRP dressing (N = 10, 50%). The mean follow-up period was 8 weeks.Results: The estimated time of wound healing was 8 weeks and healing was found to be more effective for patients in group B compared to patients in group A; the PRP group was found to be more effective in wound healing with fewer complications, less infection, exudates and pain.Conclusions: There have been considerable advances in the use of PRP in therapeutic processes in recent years in tissue regeneration therapy. PRP is a powerful tool for the treatment of chronic wounds and very promising for diabetic foot wounds; PRP enables healing, and reduces amputation rates, infection and exudates.

AbstractCellular senescence occurs when cells lose the ability to divide and proliferate. Endothelial cell senescence is associated with vascular diseases, such as atherosclerosis. In this review, I discuss the factors affecting endothelial cell senescence. Then I describe the role of microRNAs (miRNAs) in endothelial cell senescence. Understanding miRNA pathways in endothelial senescence may lead to new treatments for endothelial dysfunction and atherosclerosis.

ABSTRACT Introduction The prevalence of diabetes has been rising sharply and the rise in chronic wounds parallels this trend. Lower extremity ulcers present a serious complication for people with diabetes. While debridement of necrotic tissue and off-loading plays an important role in wound healing, many patients with diabetic foot ulcers (DFUs) fail to heal with standard of care (SOC) alone. Unresolved ulcers can lead to complications, such as osteomyelitis and amputation. There continues to be a need for the evaluation of novel wound therapies that can accelerate wound healing and lower the cost of care associated with DFUs. This paper presents recent evidence for the use of cellular and/or tissue-based products (CTPs) and offers an approach for selecting an appropriate CTP. Materials and methods A systematic literature search was conducted using PubMed, Embase, Medline, Cochrane library, and NHS Economic Evaluation Database. Full-length articles in English were assessed for relevance to select studies on effectiveness and economic evaluations. Additionally, Google Scholar was used to gather relevant literature on commonly used CTPs, including Apligraf®, EpiFix®, and Dermagraft®. Findings Results from randomized controlled trials (RCTs) provided evidence for the superior efficacy of CTPs over SOC alone in treatment of chronic DFUs. In recent studies evaluating commonly used CTPs, significantly higher number of DFUs achieved complete closure with EpiFix® when compared to either Apligraf® or Dermagraft®. While cost-effectiveness studies continue to be limited, current literature suggests that CTPs can decrease the long-term costs associated with the care of DFUs by increasing the healing rate, reducing recovery time, and lowering the risk of infection and complications. Cellular and/or tissue-based products (CTPs) may result in higher average number of ulcer-free months and lower average number of amputations or resections compared to SOC alone.

“Light amplification by stimulated emission of radiation” or more commonly known as Laser has become very popular in the field of dermatology and aesthetic medicine over the past decades. For the treatment of wound healing, a combination of different wavelengths for laser therapy has been introduced which includes 660, 800, and 970 nm. The aim of this study was to note wound healing utilizing photobiomodulation as an adjunct therapy by measuring the wound size in terms of length and width (area measurement). Study participants were selected randomly from a pool of patients who were attending for their routine follow-up visits in the Wound Care Unit in Hospital Kuala Lumpur. Eleven patients with chronic wounds of different etiologies, ie, diabetic foot ulcer and nonhealing ulcer, were recruited for this study . Wound assessment was done prior to cleansing using distilled water and followed by debridement if necessary. Subsequently, the laser technician and patients used protective goggles before applying a super intense continuous flow of laser with 3 wavelengths, ie, 660, 800, and 970 nm with 30 kJ of energy with the handpiece over a 3 min period whereby it is focused on the wound milieu and then rotated around the periwound area. There were 9 diabetic foot ulcers and 2 nonhealing ulcers treated with photobiomodulation as an adjunct therapy. All wounds were managed with the standard of care. Three wounds ie, 3 diabetic foot ulcers and 1 nonhealing ulcer were closed completely. Meanwhile, the other 7 ulcers are at 68.2% to 99% in terms of wound area reduction and new granulomatous tissue was present indicating high healing potential. Therefore, the photobiomodulation was effective as an adjunct in the management of diabetic foot and nonhealing ulcers in this case series. A larger sample size would be able to show the significance of this finding.
