Abstract
Excess free radicals at the wound site can cause an inflammatory response, which is not conducive to wound healing. Hydrogels with antioxidant properties can prevent inflammatory storms by scavenging free radicals from the wound site and inhibiting the release of inflammatory factors. In this study, we prepared the carboxymethyl chitosan (CMCS)/polyvinyl pyrrolidone (PVP)/Molybdenum (IV) Selenide (MoSe2), and platelet-rich plasma (PRP) (CMCS/PVP/MoSe2/PRP) hydrogels for accelerating the repair of wounds. In the hydrogels, the MoSe2 can scavenge various free radicals to reduce oxidative stress at the site of inflammation, endowed the hydrogels with antioxidant properties. Interestingly, growth factors released by PRP assisted the tissue repair by promoting the formation of new capillaries. CMCS as a backbone not only showed good biocompatibility and biodegradability but also played a significant role in maintaining the sustained release of growth factors. In addition, incorporating PVP enhanced the tissue adhesion and mechanical properties. The multifunctional composite antioxidant hydrogels have good swelling properties and biodegradability, which is completely degraded within 28 days. Thus, the antioxidant CMCS/PVP/MoSe2/PRP hydrogels provide a new idea for designing ideal multifunctional wound dressings.

Abstract
Ultrasound (US) has traditionally been recognised for its imaging capabilities, but its emerging role as a therapeutic modality in postoperative wound management, especially in paediatric care, has garnered significant attention. This meta-analysis aimed to evaluate the influence of US on postoperative wound healing and infection rates in paediatric patients. From an initial pool of 1236 articles, seven were deemed suitable for inclusion. Postoperative wound healing was assessed using the Redness, Edema, Ecchymosis, Discharge, and Approximation (REEDA) scale. Notably, there was a significant difference in wound healing patterns between the US-treated and control groups (I2 = 94%, standardized mean difference [SMD]: -4.60, 95% confidence intervals [CIs]: -6.32 to -2.88, p < 0.01), as illustrated in Figure 4. Additionally, a marked difference in wound infection rates was observed between the groups (I2 = 93%, SMD: -5.86, 95% CIs: -9.04 to -2.68, p < 0.01), as portrayed in Figure 5. The findings underscore the potential benefits of US in enhancing postoperative wound healing and reducing infection rates in paediatric surgical settings. However, the application of US should be judicious, considering the nuances of individual patient needs and clinical contexts.

[PMID: 36480439 PMCID: PMC10333001 DOI: 10.1111/iwj.14047] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Accepted: 11/28/2022] [Indexed: 09/10/2023] Open
Abstract
Platelet-rich plasma (PRP) has attracted attention because of its potential to accelerate the wound healing process. However, resources for evaluating research trends in the treatment of wounds with PRP were limited. In this study, we aimed to make a bibliometric analysis of the literature related to PRP in the treatment of wounds and explore the research status, hotspots and frontiers in this field in recent 20 years. Studies about PRP treatment for wounds from 2002 to 2021 were retrieved from the Science Citation Index Expanded (SCI-E) of Web of Science (WOS) database. Visualisation softwares such as VOSviewer and SCImago Graphica, and CiteSpace were used to analyse the research trends and features. A total of 1748 studies were identified in the SCI-Expanded from 2002 to 2021. The number of publications on PRP in the treatment of wounds has shown an increasing trend, from 6 (in 2002) to 228 (in 2021). The papers published in the United States have led in times cited (14637) and H-index (63). Though Italy was slightly lower than China in the number of publications, the H-index and average cited (47, 28.45) were higher than that of China (38, 27.01). The strongest keyword was "fibrin" (strength = 13.07), and the longest burst duration keyword was "thrombin" (began in 2002 and ended in 2014). The largest 10 co-citation clusters are as follows: endothelial cell proliferation (#0), regenerative medicine-associated treatment (#1), diabetic wound healing (#2), autologous derived (#3), platelet-rich fibrin (#4), tissue engineering (#5), regenerative potential (#6), clinical randomised trial (#7), histologic observation (#8), and wound bacteria (#9). The United States has made the most outstanding contribution in this field. Chinese researchers need to enhance the quality of publications further. Wound Repair Regen. is the most noteworthy journal. The mechanism of growth factors of PRP, combination therapy, preparation of PRP, and related clinical trials may be topics that need attention.

Abstract
Periodontal disease is the most common oral disease seen in dogs, and its routine treatment usually involves dental scaling. Platelet-rich plasma (PRP) therapy may enhance the effectiveness of treatment of periodontal disease, delay the progression of the disease and decrease the time under anesthesia. However, its application in dogs is rarely discussed. The objective of this study was to evaluate the benefits of activated PRP for treatment of periodontal disease in dogs. 43 mL of whole blood was collected from six adult dogs and PRP extracted using the double centrifugation tube method. Subsequently, the PRP was activated using calcium chloride (A-PRP). Significantly elevated concentrations of PDGF-BB (7000.28 pg/mL), TGF-β (378.98 pg/mL), and VEGF (7.14 pg/mL) were detected in the A-PRP. Additionally, three of the dogs with stage 2-3 periodontal disease were enrolled in the clinical trial. Periodontal pocket depth, stage of periodontal disease, gingival index, horizontal bone loss, and alveolar bone density involving the maxillary third and fourth premolar and first molar teeth (107, 108, 109, 207, 208, and 209) were evaluated. Teeth were treated by dental scaling alone (control group) or by dental scaling followed by submucosal injection of 0.1 mL A-PRP per site. After 56 days, significant improvement in periodontal pocket depth, stage of periodontal disease, gingival index, and horizontal bone loss was observed in dogs injected with A-PRP. The high concentrations of growth factors in A-PRP likely contributed to this effect. The use of submucosal injections of A-PRP to treat canine stage 2-3 periodontal disease appears safe and effective for clinical practice.

Abstract
BACKGROUND Cell therapy holds great promise for cutaneous wound treatment but presents practical and clinical challenges, mainly related to the lack of a supportive and inductive microenvironment for cells after transplantation. Main: This review delineates the challenges and opportunities in cell therapies for acute and chronic wounds and highlights the contribution of biofabricated matrices to skin reconstruction. The complexity of the wound healing process necessitates the development of matrices with properties comparable to the extracellular matrix in the skin for their structure and composition. Over recent years, emerging biofabrication technologies have shown a capacity for creating complex matrices. In cell therapy, multifunctional material-based matrices have benefits in enhancing cell retention and survival, reducing healing time, and preventing infection and cell transplant rejection. Additionally, they can improve the efficacy of cell therapy, owing to their potential to modulate cell behaviors and regulate spatiotemporal patterns of wound healing. CONCLUSION The ongoing development of biofabrication technologies promises to deliver material-based matrices that are rich in supportive, phenotype patterning cell niches and are robust enough to provide physical protection for the cells during implantation.

Abstract
Diabetic ulcer is a serious complication of diabetes. Compared with that of healthy people, the skin of patients with a diabetic ulcer is more easily damaged and difficult to heal. Without early intervention, the disease will become increasingly serious, often leading to amputation or even death. Most current treatment methods cannot achieve a good wound healing effect. Numerous studies have shown that a nanocomposite hydrogel serves as an ideal drug delivery method to promote the healing of a diabetic ulcer because of its better drug loading capacity and stability. Nanocomposite hydrogels can be loaded with one or more drugs for application to chronic ulcer wounds to promote rapid wound healing. Therefore, this paper reviews the latest progress of delivery systems based on nanocomposite hydrogels in promoting diabetic ulcer healing. Through a review of the recent literature, we put forward the shortcomings and improvement strategies of nanocomposite hydrogels in the treatment of diabetic ulcers.

Abstract
Besides their primary role in hemostasis, platelets contain a plethora of immunomodulatory molecules that profoundly affect the entire process of wound repair. Therefore, platelet derivatives, such as platelet-rich plasma or platelet lysate, have been widely employed with promising results in the treatment of chronic wounds. Platelet derivatives provide growth factors, cytokines, and chemokines targeting resident and immigrated cells belonging to the innate and adaptive immune system. The recruitment and activation of neutrophils and macrophages is critical for pathogen clearance in the early phase of wound repair. The inflammatory response begins with the release of cytokines, such as TGF-β, aimed at damping excessive inflammation and promoting the regenerative phase of wound healing. Dysregulation of the immune system during the wound healing process leads to persistent inflammation and delayed healing, which ultimately result in chronic wound. In this review, we summarize the role of the different immune cells involved in wound healing, particularly emphasizing the function of platelet and platelet derivatives in orchestrating the immunological response.

Abstract
INTRODUCTION Microbial invasion in soft tissue is believed to cause infectious wounds and increase healthcare costs, anxiety, and distress. The current study was conducted to evaluate the effects of topical use of platelet-rich plasma (PRP) on infected wound-healing process in rats. METHODS Following the induction of a circular wound, the animals were divided into three groups, including (1) standard control: infected wounds treated with mupirocin (SDCL), (2) non-infected wounds treated with PRP (PRP), and (3) infected group in which the rats were infected with Staphylococcus epidermidis and Pseudomonas aeruginosa and treated with PRP (INF + PRP). To evaluate the effects of PRP on the wound-healing rate, total bacterial count, histopathological assessment, the serum concentrations of sialic acid, C-reactive protein, haptoglobin, and fibrinogen were assessed. Additionally, IL-1β, IL-6, TNF-α, IL-3, NF-κB, iNOS, PDGF, and EGF mRNA level expressions were assessed employing the qRT-PCR method. RESULTS The results indicated that topical application of PRP could significantly decrease total bacterial count, the level of C-reactive protein, and pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α) compared to the SDCL group. The administration of PRP also promoted re-epithelization rate by increasing the expression of EGF mRNA level. CONCLUSION We could recommend the use of PRP for the treatment of infected wounds owing to its efficiency in decreasing colonization of tissue bacteria, tissue inflammation, and stimulating wound heal-up.

Abstract
BACKGROUND Anal fissure is one of the most common benign anal disorders, and medical treatments play an important role in its management. OBJECTIVE The purpose of this study was to investigate the short-term effects and success of platelet-rich plasma in the treatment of chronic anal fissure. DESIGN The study is a 2 parallel group, randomized, controlled clinical trial. SETTINGS The study was performed in 2 tertiary university hospitals. PATIENTS Forty-four patients with chronic anal fissure were randomly assigned to platelet-rich plasma treatment or control group. Presenting symptoms and pain scores were recorded on enrollment. The control patient self-administered topical glyceryl trinitrate. Platelet-rich plasma was injected locally in the intervention group followed by self-administered glyceryl trinitrate. MAIN OUTCOME MEASURES The primary outcome measure is a reduction in pain scores. RESULTS On day 10 and 1 month after treatment, the mean pain score was significantly lower in the patients treated with platelet-rich plasma than in the controls (p = 0.005 and p < 0.005). By 1 month after treatment, the mean pain score declined by 5.7 points in the platelet-rich plasma-treated group compared with a 4.1 mean pain score decline in the control group (mean difference:1.6 points (95% CI, 0.3-2.9)). According to the repeated-measures analyses, pain scores decreased in both groups, but the decrease in the treatment group was statistically higher than in the control group (p < 0.001). Complete epithelialization and recovery rates were significantly higher in the platelet-rich plasma group than in controls at all follow-up times, with p values ranging from 0.034 to <0.001. The observed difference in complete epithelialization after 2 months of treatment between the platelet-rich plasma group and the control group was 56.2% with a 95% CI of 14.03% to 98.4%. LIMITATIONS This study was limited by its small sample size, and long-term follow-up of the patients was not presented. CONCLUSIONS Platelet-rich plasma reduced concerns and accelerated epithelialization and healing in patients with chronic anal fissures.

Los síntomas de presentación y las puntuaciones de dolor se registraron en la inscripción. Los pacientes de control se autoadministraron trinitrato de glicerilo tópico. El plasma rico en plaquetas se inyectó localmente en el grupo de intervención seguido de trinitrato de glicerilo autoadministrado. PRINCIPALES MEDIDAS DE RESULTADO La principal medida de resultado es una reducción en las puntuaciones de dolor. RESULTADOS El día 10 y un mes después del tratamiento, la puntuación media de dolor fue significativamente menor en los pacientes con plasma rico en plaquetas que en los controles (p = 0.005 y p <0.005, respectivamente). Un mes después del tratamiento, la puntuación media de dolor disminuyó 5.7 puntos en el grupo tratado con plasma rico en plaquetas en comparación con una disminución de la puntuación media de dolor de 4.1 en el grupo de control (diferencia media: 1.6 puntos [intervalo de confianza del 95%; 0.3-2.9] Según los análisis de medidas repetidas, las puntuaciones de dolor disminuyeron en ambos grupos, pero la disminución en el grupo de tratamiento fue estadísticamente mayor que en el grupo de control (p <0.001). Las tasas de epitelización completa y recuperación fueron significativamente más altas en los pacientes con plasma rico en plaquetas que en los controles en todos los tiempos de seguimiento, con valores de p que van desde 0.034 a <0.001. La diferencia observada en la epitelización completa después de dos meses de tratamiento entre el grupo de plasma rico en plaquetas y el grupo de control fue del 56.2% con un intervalo de confianza del 95% del 14.03% al 98.4%. LIMITACIONES Este estudio estuvo limitado por el pequeño tamaño de la muestra y porque no se proporcionó un seguimiento a largo plazo de los pacientes. CONCLUSIONES El plasma rico en plaquetas redujo las molestias y aceleró la epitelización y la curación en pacientes con fisuras anales crónicas.

Abstract
Platelet preparations are autologous blood concentrates with supraphysiologic concentrations of platelets with or without leukocytes used in various clinical applications including regenerative medicine, wound healing, and facial rejuvenation. Their use harnesses the important role of platelets and their secretory products in immunoregulation, wound healing, angiogenesis, and tissue remodeling. The use of platelet preparations has been long documented in orthopaedic surgery, maxillofacial surgery, and other fields, but over the years research has increased in their application to facial plastic surgical techniques. Here we review the various formulations of platelet rich concentrates, their applications to facial skin rejuvenation, wound healing, scar reduction, and tissue fill as documented in the literature since 2018.

Abstract
In the present study, the age- and sex-related differences in platelet ultrastructure were investigated using transmission electron microscopy (TEM). A total of 15 healthy volunteers were grouped according to age, with 5 people in each of the following groups: young group (25-45 years), middle-aged group (46-65 years), and old-aged group (> 65 years). In the TEM micrographs, the internal components, specifically the α-granules, dense granules, and lysosomal granules, of 20 platelets were counted for each group. Two-way analysis of variance of age and sex variance was used to compare the results. The ultrastructure of the platelets in the old-aged group was observed to be quite different from those of the young and middle-aged groups. Specifically, with ageing, the platelet membrane becomes more irregular in shape and non-smooth, and multiple platelet membrane ruptures are observed. Furthermore, the pseudopodia and protuberances become more numerous and slender, and the number of α-granules is significantly reduced. These morphological changes indicate that ageing may affect the function of platelets, which in turn affects the efficacy of platelet concentrates. Thus, the effects of age should be considered when using platelet concentrates prepared from elderly autologous blood.

Abstract
Native platelets perform several critical functions within the context of wound healing, including participating in initial hemostasis and interacting with fibrin at the wound site to induce clot retraction. Platelet depletion or dysfunction due to trauma or disease can inhibit robust wound healing responses. There has been a focus recently on developing synthetic, non-immunogenic platelet mimetic technologies for the purpose of augmenting hemostatic responses in cases of deficient native platelet functionality. Here we describe the application of synthetic platelet-like particles (PLPs), capable of recapitulating the deformable platelet body and fibrin specificity found in native platelets, to enhance healing outcomes. We first demonstrate PLPs mimic activated platelet morphology and induce fibrin clot retraction. During clot retraction, native platelets generate forces within a fibrin network to stiffen the fibrin matrix; therefore, we hypothesized that our PLPs will likewise be able to stiffen provisional fibrin matrices. Due to previous studies indicating that increased matrix stiffness is linked to increased cellular migration, we further hypothesize that PLP-mediated fibrin stiffening will enhance cell migration and improve healing outcomes within in vitro and in vivo models of wound healing. PLPs were found to enhance fibroblast migration in in vitro models of early wound healing and enhance healing outcomes in an in vivo murine model of wound healing. These studies demonstrate the utility of PLPs for enhancing wound repair and also provide insight into the role of native platelet-mediated clot retraction in wound healing.

Abstract
Wound healing remained an equation with multiple variables that experts in the medical field are trying to solve. The need to find an adjuvant that can quicken the healing process is increasing with every day, as longer wound healing times raise the risk of infections. Platelet-rich plasma is a promising tool promoting faster healing in a variety of wounds (thermal wounds, burn wounds, surgeries, etc.), as a series of studies present encouraging results in patients that received platelet-rich plasma treatment. The aim of this paper is to review and comment on the useful benefits and limitations of using platelet-rich plasma as an adjuvant strategy in wound healing, emphasizing on skin related wounds.

Abstract
Platelet-rich plasma (PRP) is widely used nowadays in different fields of medicine, affecting physiological processes including tissue regeneration. The use of PRP in maxillofacial surgical interventions and its efficiency in the improvement of postoperative wound healing were analysed. Patients undergoing plastic and reconstructive surgeries in the maxillofacial region were recruited: 50 patients were enrolled into a control group (received no PPRP injection) and 50 patients were enrolled into a treatment group, where PRP was applied during the surgical procedure. Evaluation of treatment outcomes was carried out by determination of IL-1β, TNFα, and IL-6 cytokines levels in the wound-drain fluid. The stages of wound healing were assessed by cytological analyses and ultrasound within a month period. The use of the PRP has substantially positive effects, contributing to the improvement of the healing process. In the treatment group, fibroblasts, macrophages, and collagen fibres appeared and their quantities increased earlier than when compared with control group patients. The concentration of IL-1β and TNFα in wound fluid on day 1 and day 5 after operation was higher for the treatment group as opposed to the control group, which was linked to the influence of PRP on inflammatory and granulation phases of the healing process. An ultrasound examination showed less oedema and infiltration in the tissues around the wound of the treatment group.
