Sin A, Hollabaugh W, Porras L. Narrative review and call to action on reporting and representation in orthobiologics research for knee osteoarthritis. PM R 2024. [PMID: 38970438 DOI: 10.1002/pmrj.13214] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 03/29/2024] [Accepted: 04/03/2024] [Indexed: 07/08/2024]
Abstract
Osteoarthritis affects a significant portion of U.S. adults, and knee osteoarthritis contributes to 80% of disease burden. Previous data have shown that non-White patient populations often report worse symptoms and less favorable outcomes following arthroplasty, a definitive treatment for knee osteoarthritis. There is a lack of demographics data on race/ethnicity, as well as socioeconomic status (SES) and social determinants of health (SDOH), in knee osteoarthritis treatment guidelines and knee arthroplasty research. In addition, there is underrepresentation of non-White patient populations in the existing treatment guidelines for knee osteoarthritis. Over the past decade, orthobiologics have emerged as an alternative to surgical intervention. Our hypothesis is that there would be a similar lack of reporting of demographics data and underrepresentation of non-White populations in studies pertaining to orthobiologics, including evaluating differences in outcomes. This study reviewed U.S.-based research in orthobiologics as a treatment option for knee osteoarthritis. We identified a lack of demographics reporting in terms of race/ethnicity, and none of the studies reported SES or SDOH. Non-White populations were underrepresented; White patients contributed to 80% or more of all study populations that reported race/ethnicity. None studied the correlation between symptoms and outcome measures, and the race/ethnicity, SES, and SDOH of the patients. Based on a review of existing literature, we strongly advocate for ongoing research encompassing patients of all races/ethnicities, SES, and SDOH, and an exploration into potential variations in symptoms and outcomes among distinct population subgroups. Furthermore, SES barriers may influence health care delivery on orthobiologics for disadvantaged populations.

Abstract
Tendinopathy poses a significant clinical challenge characterized by chronic tendon pain, swelling, and impaired function, affecting athletes and the general population. Current treatments often provide limited success, necessitating exploration into regenerative therapies such as platelet-rich plasma (PRP). PRP harnesses the regenerative potential of autologous platelets and growth factors to promote tendon healing. This review aims to comprehensively examine the mechanisms, efficacy, and clinical applications of PRP in tendinopathy. We discuss the pathophysiology of tendinopathy, highlighting collagen disorganization, increased ground substance, and inflammatory changes. PRP's action mechanism involves releasing bioactive molecules that stimulate cellular proliferation, collagen synthesis, and tissue remodeling. Clinical studies and trials evaluating PRP in various tendinopathies, including Achilles, patellar, and rotator cuff tendinopathy, are reviewed to assess its efficacy and effectiveness compared to traditional therapies. Practical aspects, such as preparation methods, injection techniques, and safety considerations, are discussed to provide insights into optimal PRP administration. Challenges, including protocol variability and evidence gaps, are addressed, and future research and clinical practice directions are proposed. By synthesizing current knowledge, this review aims to guide clinicians in enhancing treatment strategies and advancing the field of tendon regenerative medicine.

Abstract
Rotator cuff repair surgeries fail frequently, with 20 to 94% of the 600,000 repairs performed annually in the United States resulting in retearing of the rotator cuff. The most common cause of failure is sutures tearing through tendons at grasping points. To address this issue, we drew inspiration from the specialized teeth of snakes of the Pythonoidea superfamily, which grasp soft tissues without tearing. To apply this nondamaging gripping approach to the surgical repair of tendon, we developed and optimized a python tooth-inspired device as an adjunct to current rotator cuff suture repair and found that it nearly doubled repair strength. Integrated simulations, 3D printing, and ex vivo experiments revealed a relationship between tooth shape and grasping mechanics, enabling optimization of the clinically relevant device that substantially enhances rotator cuff repair by distributing stresses over the attachment footprint. This approach suggests an alternative to traditional suturing paradigms and may reduce the risk of tendon retearing after rotator cuff repair.

Comparative evaluation of platelet-rich plasma, autologous blood serum, and umbilical cord serum for corneal healing after penetrating keratoplasty in New Zealand rabbits. Exp Eye Res 2024; 240:109779. [PMID: 38176514 DOI: 10.1016/j.exer.2023.109779] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 11/24/2023] [Accepted: 12/31/2023] [Indexed: 01/06/2024]
Abstract
This study aimed to evaluate the effects of platelet-rich plasma (PRP), autologous blood serum (ABS), and umbilical cord serum (UCS) on corneal healing following penetrating keratoplasty (PK). A total of 120 New Zealand white rabbits, forty were designated as donors, while the remaining eighty rabbits were randomly divided into four groups after undergoing PRP Group (n = 20), ABS Group (n = 20), UCS Group (n = 20) and Control Group (n = 20). Corneal opacity score, corneal vascularization, corneal staining, histopathological analysis, and immunohistochemical analysis (including CD4+, CD8+, and major histocompatibility complex [MHC] II) were assessed at postoperative 1, 2, 3, and 12 weeks. The results showed that corneal opacity score and corneal vascularization did not differ significantly among the groups. However, corneal staining was found to be statistically higher in the PRP group (0.40 ± 0.60) compared to the other groups (p = 0.011). Immunohistochemical examination revealed no significant differences in CD4+, CD8+, and MHC II levels among the groups. Notably, in all groups, CD4+, CD8+, and MHC II levels were significantly higher at 12 weeks compared to other time points. PRP, ABS, and UCS demonstrated positive effects on corneal healing after PK. However, among the three products, PRP exhibited a superior healing effect compared to ABS and UCS crucial in the postoperative period following PK procedures, as they significantly impact visual quality, graft transparency, graft survival, and prevention of stromal resorption caused by infections. Despite the avascular nature of the cornea and its immune privilege, failure to resolve epithelial defects (ED) commonly observed after PK can result in irreversible scarring and ulceration, leading to graft rejection. While epithelial defects are observed in 14-100% of cases on the first postoperative day, approximately 3-7% of them persist as non-healing ED in subsequent periods. In conclusion, our study demonstrated that PRP, ABS, and UCS have a positive effect on corneal healing after PK.

Abstract
As an abundant supplier of growth factors, chemokines and other bioactive molecules, platelet rich plasma (PRP) become a leading therapy for tissue regeneration. The PRP therapy is an inexpensive and feasible source of growth factor compared to commercial products however, the better source of platelets is the major challenge. Many researchers are skeptical about cord blood as an alternative source for the allogenic preparation of PRP. In the present study, we have compared adult peripheral and cord blood PRP for their regenerative capacity and immuno-modulatory nature. ELISA data indicates that the cord PRP contained a considerably higher amount of growth factors compared to adult PRP. In-vitro results indicate a significant increase in cell proliferation and migration with cord PRP treatment. The immunomodulatory evaluation shows cord blood PRP has better potential in switching activated macrophages to anti-inflammatory markers when compared with adult PRP, as well as the cytokines production indicates a significant reduction in the release of IFN-γ in cord PRP treatment. The study shows the beneficial effects of using cord blood PRP over adult PRP however, future studies are required to validate cord blood PRP as a permanent source for regenerative therapy.

Abstract
This study was designed to evaluate the efficiency of the combination of autologous platelet-rich plasma gel (APG) and Manuka honey gauze in the treatment of Stages 3-4 pressure injury of older adults. Patients were divided into four groups: Manuka honey gauze and APG (M + A), Manuka honey gauze (M), APG (A), and a control group (C). Different treatments were given, then wound bed coverage with granulation tissue, wound size reduction, and Pressure Ulcer Scale for Healing (PUSH) score were examined. Paraffin-embedded sections of wound tissues were analyzed and wound swab cultures were assessed. Kruskal-Wallis test and Mann-Whitney U test were performed in statistical analysis at a 5% significance level. A total of 42 patients were accepted. Significant increase of wound bed coverage with granulation tissue (51.24%, P = .004, Kruskal-Wallis test) and decrease of PUSH score (-5) were observed in the M + A group at the end of the observation (P = .032, Mann-Whitney U test). The hematoxylin-eosin staining of wound tissues showed that typical squamous epithelium was seen in wound bed of patient in M + A group. Manuka honey gauze and APG were proved to be superior treatments for pressure injury of old patient. Increase of granulation tissue coverage, reduction of PUSH score, and improved growth of epithelium were observed in M + A group. There was no side-effect, and the treatment would not cause infection.

Abstract
Platelet-rich plasma (PRP) has emerged as a promising therapy in regenerative medicine. However, the lack of standardization in PRP preparation protocols presents a challenge in achieving reproducible and accurate results. This study aimed to optimize the PRP preparation protocol by investigating the impact of two different anticoagulants, sodium citrate (SC) and ethylenediaminetetraacetic acid (EDTA), and resuspension media, plasma versus sodium chloride (NaCl). Platelet recovery rates were calculated and compared between groups, in addition to platelet activity and vascular endothelial growth factor (VEGF) released into plasma after PRP activation. The platelet recovery rate was higher with EDTA in comparison to SC (51.04% vs. 29.85%, p = 0.005). Platelet activity was also higher, with a higher expression of two platelet antibodies, platelet surface P-Selectin (CD62p) and PAC-1, in the EDTA group. The concentration of VEGF was higher with SC in comparison to EDTA (628.73 vs. 265.44 pg/mL, p = 0.013). Platelet recovery rates and VEGF levels were higher in PRP resuspended in plasma when compared to NaCl (61.60% vs. 48.61%, p = 0.011 and 363.32 vs. 159.83 pg/mL, p = 0.005, respectively). Our study reinforces the superiority of EDTA (as anticoagulant) and plasma (for resuspension) in obtaining a higher platelet recovery and preserving platelet functionality during PRP preparation.

Abstract
Platelet-rich plasma (PRP) is a concentrated platelet preparation known for its regenerative properties due to the various growth factors it contains. Its application in the medical field, including dentistry, gynecology, and plastic surgery, has surged. In obstetrics and gynecology, PRP has shown promise in improving low libido, vaginal rejuvenation, ovarian reserve, and endometrial receptivity. This study presents a 29-year-old woman experiencing primary infertility attributed to low levels of anti-Müllerian hormone alongside the presence of asthenozoospermia in her husband's semen. After failed intrauterine insemination as well as in vitro fertilization (IVF), attempts at laparoscopic PRP treatment were administered before the second IVF cycle to enhance ovarian reserve and quality. The PRP treatment led to an increased follicle count, improved oocyte quality, and a successful pregnancy outcome in the second IVF cycle. PRP treatment promises to be effective in fertility treatments, potentially increasing ovarian reserve, improving oocyte quality, and enhancing successful pregnancy outcomes. This case report highlights its beneficial impact on a couple facing primary infertility, providing hope for patients with similar reproductive challenges.

Abstract
Breast cancer treatment encompasses various therapeutic modalities, including surgery, radiotherapy, and chemotherapy. Breast-conserving surgery has been an integral part of breast cancer management. However, radiotherapy, an important component of breast cancer management, can lead to complications, particularly fibrosis, affecting reconstructive surgery outcomes. We conducted an in vivo study using 48 female Wistar Albino rats, employing segmental mastectomy and radiotherapy to simulate post-mastectomy conditions. The rats were divided into six groups: control, mastectomy, mastectomy + radiotherapy, mastectomy + platelet-rich plasma (PRP) + radiotherapy, mastectomy + infliximab + radiotherapy, and mastectomy + infliximab + PRP + radiotherapy. Edema, hyperemia, inflammation, and fibrosis were assessed as indicators of tissue response. Histopathological analysis revealed that mastectomy + infliximab and mastectomy + infliximab + PRP groups showed significant reductions in fibrosis compared to other groups. Edema, hyperemia, and inflammation were also less severe in these groups compared to the control group. Radiotherapy-induced fibrosis is a major concern in breast reconstruction. Our study suggests that local PRP application and systemic infliximab administration, either alone or in combination, could mitigate the adverse effects of radiotherapy. This approach has the potential to improve reconstructive outcomes in patients undergoing or having the possibility to undergo radiotherapy. This is the first study showing the effectiveness of infliximab and PRP combination on wound healing. The provided experimental rat model might offer guidance for further research. This study provides insights into optimizing outcomes in reconstructive breast surgery, paving the way for further research and clinical studies.

Abstract
Platelet concentrates such as platelet-rich plasma, platelet-rich fibrin or concentrated growth factors are cost-effective autologous preparations containing various growth factors, including platelet-derived growth factor, transforming growth factor β, insulin-like growth factor 1 and vascular endothelial growth factor. For this reason, they are often used in regenerative medicine to treat wounds, nerve damage as well as cartilage and bone defects. Unfortunately, after administration, these preparations release growth factors very quickly, which lose their activity rapidly. As a consequence, this results in the need to repeat the therapy, which is associated with additional pain and discomfort for the patient. Recent research shows that combining platelet concentrates with biomaterials overcomes this problem because growth factors are released in a more sustainable manner. Moreover, this concept fits into the latest trends in tissue engineering, which include biomaterials, bioactive factors and cells. Therefore, this review presents the latest literature reports on the properties of biomaterials enriched with platelet concentrates for applications in skin, nerve, cartilage and bone tissue engineering.

Abstract
Vesicovaginal fistula is a cause of deterioration in the quality of life. It is a communication between the bladder and vagina resulting in the uncontrollable leakage of urine through the vagina. Recently, regenerative methods have been used more frequently, and platelet-rich plasma is one of these methods. The functional properties of platelet-rich plasma are based on the synthesis and secretion of multiple growth factors released after platelet activation. The aim of this study was to investigate how platelet-rich plasma influences the condition of the tissue and the healing ability of the urothelium, vaginal epithelium and tissues surrounding the fistulous canal. The study included eight patients who had undergone the Latzko procedure aimed at closing the vesicovaginal fistula. Samples were collected during primary surgery without platelet-rich plasma and after failed surgery, during a second attempt. The specimens were subjected to histological and immunohistochemical evaluation. The histology demonstrated that in platelet-rich plasma patients, greater vascularization and wider subepithelial mucosa layering was observed. Inflammatory infiltration in the subepithelial layer was increased in platelet-rich plasma patients. No localization differences in growth factor proteins were found in either group, but in platelet-rich plasma-patients, the reactions were stronger. It can be concluded that the use of platelet-rich plasma improves the morphological structure of the injected tissues.

Abstract
OBJECTIVE Aim: of our study was to improve the pregravid preparation of women with chronic endometritis to develop individual approaches to overcoming infertility, taking into account the state of endometrium. PATIENTS AND METHODS Materials and Methods: The study included 90 women (main group, n=90), 28 to 38 years with an anatomically normal uterus and chronic endometritis (CE). Patients were divided into 2 groups: group I - 45 women with CE who received conventional treatment; group II - 45 women with CE who received pregravid preparation by subendometrial injections of Platelet-Rich Plasma (PRP). RESULTS Results: At the first stage of study, the ART statistical reports from 2015 to 2022 were analyzed at the Medical Center of Reproductive Health ≪Damia≫, (Ivano-Frankivsk). Analysis of the vaginal flora parameters before treatment at the first stage revealed the presence of conditionally pathogenic flora in culture from the cervical canal (Candida albicans - 2.4%, Escherihia coli - 4.8%, Staphylococcus epidermidis - 6.2% Enterococcus faecalis - 6.9%), and was evidence of a possible recurrence of inflammation during gestation. In the age category, the groups of patients were homogeneous, with no significant differences by the level of AMH and the level of CD 138. Biochemical pregnancy be present in 20 patients (44.4%) of group I and 28 (62.2%) of group II. Fertility within a year after the end of therapy was restored with the proposed method of therapy in most women (51.1%), in the comparison group this number was 11.1% lower. Pregnancy rate between the groups (I and II) did not differ significantly. The number of live births in group II - 19 births (42.2%) - was 2 times higher than I group (9 (20.0%), P<0.05). The most common complication for women in the comparison groups was early pregnancy loss. Among 18 (40.0%) clinical pregnancies of group I, 8 women (17.8%) had early miscarriage, 1 ectopic pregnancy (2.2%), while in group II clinical pregnancy be present in 23 women (51.1%). The number of terminated pregnancies was two times lower than in the first group (8.9% vs. 17.8%, P<0.05). CONCLUSION Conclusions: Chronic endometritis is one of the main causes of pregnancy loss after in vitro fertilization. Patients of the second group were treated with the proposed method of subendometrial injections with Platelet-Rich Plasma (PRP), prepared from autologous blood, is an effective method of preparing the endometrium for embryo transfer and can increase the number of live births in patients with chronic endometritis.

Abstract
Stem cell therapies have become widely popular in orthopaedic surgery, with a recent interest in adipose-derived therapeutics. Adipose-derived mesenchymal signaling cells (ADSCs) and micronized adipose tissue (MAT) are unique therapies derived from different processing methods. Characterizing the most influential studies in lipoaspirate research can help clarify controversies in definitions, identify core literature, and further collective knowledge for educational purposes. The Science Citation Index Expanded subsection of the Web of Science Core Collection was systematically searched to identify the top 50 most cited publications (based on citation/year) on orthopaedic ADSCs or MAT research. Publication and study characteristics were extracted and reported using descriptive statistics. Level of evidence was assessed for applicable studies, and Spearman correlations were calculated to assess the relationship between citation data and level of evidence. The top 50 articles were published between the years 2003 and 2020, with 78% published in the year 2010 or later. The mean number of citations was 103.1 ± 81.1. The mean citation rate was 12.4 ± 6.0 citations per year. Of the 21 studies for which level of evidence was assessed, the majority were level III (10, 47.6%). The single study design most common among the top 50 cited articles was in vitro basic science studies (17 studies, 34%). Twenty-nine articles (58%) were classified as basic science or translational. Application to treat knee osteoarthritis was the most common focus of studies (14 studies, 28%), followed by in vitro analysis of growth factor and cell signaling markers (11 studies, 22%). No correlation was found between rank, citation rate, or year of publication and level of evidence. This study provides a current landscape on the most cited articles in lipoaspirates in orthopaedic surgery. With the expansion of ADSCs and MAT in the past two decades, this study provides the first historical landmark of the literature and a launching point for future research. Studies should explicitly state their processing methodology and whether their study investigates ADSCs or MAT to avoid misinformation.

Abstract
Cubital tunnel syndrome (CuTS) is a neuropathic condition characterized by the compression or irritation of the ulnar nerve at the elbow, resulting in a wide spectrum of symptoms ranging from pain and numbness to muscle weakness and impaired hand function. This comprehensive review delves into the diverse landscape of CuTS treatment approaches, emphasizing the importance of early intervention. The review explores how these strategies aim to alleviate symptoms and enhance patient well-being by beginning with conservative measures encompassing rest, splinting, medications, physical therapy, and lifestyle adjustments. Non-surgical medical interventions, including nerve gliding exercises, ultrasound-guided nerve injections, and orthotic devices, are considered alternative therapies for symptom relief. Surgical interventions, such as decompression procedures and emerging techniques, are discussed in detail, highlighting their indications and expected outcomes. Throughout this review, the critical role of patient-centered care is underscored, emphasizing the need for tailored treatment plans that respect individual preferences and goals. Recognizing the unique nature of each CuTS case, shared decision-making between patients and healthcare providers is advocated, ensuring that interventions align with specific patient needs. As research advances, promising developments in diagnosis, surgical techniques, and drug therapies offer hope for more effective management of CuTS, paving the way for improved symptom relief and enhanced nerve function.

Abstract
Endometrial receptivity is an important factor that influences embryo implantation. Thus, it is important to identify an applicable approach to improve endometrial receptivity in women undergoing assisted reproductive technology. Recently, growing evidence has indicated that intrauterine platelet-rich plasma (PRP) infusion is an effective method to obtain a satisfactory reproductive outcome by increasing endometrial thickness and improving endometrial receptivity. Therefore, the present review aims to outline the possible mechanisms of PRP on endometrial receptivity and summarize the present literature on the effects of PRP therapy in improving endometrial receptivity.

Abstract
Diabetic non-healing wounds are bringing a heavy burden on patients and society. Platelet-rich plasma (PRP) has been widely applied in tissue regenerating for containing various growth factors. Recently, PRP-derived exosomes (PRP-Exos) have been proved to be more effective than PRP in tissue regeneration. However, few studies have investigated the therapeutic potential of PRP-Exos in diabetic wound healing to date. Therefore, we extracted and identified exosomes derived from PRP and tested its promoting effect on diabetic wound healing in vivo and in vitro. We found that high glucose (HG) inhibited cell proliferation and migration and induced apoptosis through ROS-dependent activation of the JNK and p38 MAPK signaling pathways. PRP-Exos can stimulate fibroblast functions and accelerate diabetic wound healing. The benefits of PRP-Exos may be attributed to its capability to prevent HG-induced ROS-dependent apoptosis via the PDGF-BB/JAK2/STAT3/Bcl-2 signaling pathway. This illustrates the therapeutic potential of PRP-Exos in diabetic wounds.

Abstract
OBJECTIVES Platelet-rich plasma (PRP) is obtained by centrifuging the platelet-rich portion of the patient's own blood. The objective of our study is to retrospectively examine the impact of intraovarian PRP injection on infertile women with diminished ovarian reserve, specifically focusing on the oocyte count, oocyte quality, and endometrial thinning. METHODS A retrospective assessment was conducted on cases who had intraovarian PRP injection at the in vitro fertilization (IVF) unit of the Obstetrics and Gynecology Department of Gazi University School of Medicine hospital. The review encompasses the period from 1 January 2015 to 30 June 2020. The endometrial thickness, follicle count of greater than 14 millimeters, estradiol levels, follicle-stimulating hormone (FSH) levels, and antral follicle count were assessed during the menstrual cycle both prior to and within a period of 1-6 months following the PRP procedure. Twenty nonpregnant patients who had IVF before and 4-6 months after PRP were admitted to the post-PRP IVF cycle. The quantification of oocytes and M2 oocytes was conducted both prior to and subsequent to PRP treatment. RESULTS Among 120 cases, only 60 cases who fulfilled inclusion criteria were analyzed. The basal endometrial thickness, basal follicle number (>14 mm), estradiol value, oocyte count, and M2 oocyte count exhibited a statistically significant increase following the administration of PRP injection (p<0.001). The basal FSH value exhibited a notable drop following the administration of PRP injection, with a statistically significant difference (p=0.002). In the pregnant group, the number of oocytes obtained with oocyte pick-up (OPU) increased by 300%, and in the nonpregnant group, the increase was 125% only. The number of M2 oocytes obtained with OPU increased by 250% in the pregnant group, while it was 93% in the nonpregnant group. CONCLUSION Ultimately, the affordability of PRP production and its considerable theoretical efficacy have the potential to substantially decrease the expenses associated with assisted reproductive technology procedures. In the present scenario, the administration of an intraovarian PRP injection may be contemplated as a therapeutic intervention for women exhibiting diminished ovarian reserve.

Abstract
Platelet-rich plasma (PRP) has been increasingly used in sports medicine owing to its various advantages. The purpose of our project was to standardize the parameters before performing large-scale clinical trials in the near future to precisely evaluate individual PRP quality. To examine the effects of regular exercise on PRP quality, this study focused on young female athletes, who have been relatively less studied. Blood samples were obtained from female college athletes (n = 35) and ordinary healthy adults (n = 30), which were considered as controls, and leukocyte-rich PRP (L-PRP) was prepared manually. Body composition indices were determined using a bathroom weight scale equipped with an impedance meter. Growth factors and cytokines were quantified using ELISA kits. Platelet-derived growth factor-BB (PDGF-BB) and Transforming-growth factors β1 (TGFβ1) levels (per platelet) in L-PRP were significantly lower in female athletes than in controls. In contrast, Interleukin-1β and Interleukin 1 receptor antagonist (IL-1RA) levels (per platelet and L-PRP) in L-PRP were significantly higher in athletes, and this difference was more prominent in IL-1RA. These findings suggest that L-PRP from athletes may facilitate the inflammatory phase of the healing process by regulating the pro-inflammatory and anti-inflammatory balance. These chemical compositions can be adopted as "must-check" parameters to characterize individual PRP preparations prior to clinical trials.

Abstract
This report examines the efficacy of platelet releasate injection as a treatment method for ulnar neuritis. Platelet-rich plasma (PRP), an autologous product of concentrated platelets, has the potential to accelerate healing in injured peripheral nerves by releasing growth factors that promote nerve repair. Platelet releasate, the supernatant of thrombin-activated PRP, has yet to be thoroughly investigated as a treatment option for ulnar neuritis. In this report, a 42-year-old female patient presented with right-sided elbow and neck pain that was subsequently diagnosed as ulnar neuritis and neurogenic thoracic outlet syndrome. Initial imaging at the right elbow demonstrated ulnar nerve entrapment within the arcade of Struthers. The patient's symptoms were first managed with home exercise and ulnar nerve hydrodissection at the elbow, which decreased but did not resolve her pain. Platelet releasate injection of the ulnar nerve at the elbow was subsequently performed. Six weeks post-procedure, the patient reported additional pain improvement. Provocative tests at the elbow were negative and imaging demonstrated a normal-appearing ulnar nerve. Despite these results, the patient was not completely symptom-free; persistent symptoms were attributed to her concomitant neurogenic thoracic outlet syndrome. While platelet releasate injection has not previously been explored as a treatment option for ulnar neuritis, this case demonstrates how platelet releasate injection may facilitate healing in an ulnar nerve injured by entrapment. Further investigation could support platelet releasate injection as an effective monotherapy or as an adjunct treatment for ulnar neuritis and similar peripheral neuropathies.

Abstract
Orthobiologics are playing an increasingly large role in the clinical setting across multiple fields of surgery. Particularly, in the field of orthopedic surgery, the employment of platelet-rich plasma (PRP) therapy in total joint arthroscopy (TJA) has become popular for its prompted benefits of controlling pain, blood loss, and increased wound healing. PRP was originally used for thrombolytic conditions, however, the aforementioned potential benefits have led to its increased use across various fields of medicine including dermatology, neurosurgery, orthopedics, and sports medicine. Currently, there is a persisting gap in the literature surrounding the mechanism of action of PRP, as well as its true role in increasing positive patient outcomes in the context of TJA. Thus, this review aims to briefly highlight the physiological mechanisms underlining PRP therapy, evaluate recent preclinical and clinical data about its effects on TJA patient outcomes, and to describe its concomitant use in novel orthopedic-applications.

Abstract
Androgenetic alopecia (AGA), also known as male pattern hair loss (MPHL) or female pattern hair loss (FPHL), is the most common form of alopecia worldwide, and arises from an excessive response to androgens. AGA presents itself in a characteristic distribution unique to both sexes. Despite its prevalence, AGA can be quite challenging to treat. The condition is chronic in nature and stems from an interplay of genetic and environmental factors. There are only two US Food and Drug Administration (FDA)-approved drugs for the condition: topical minoxidil and oral finasteride. However, numerous non-FDA-approved treatments have been shown to be effective in treating AGA in various studies. Some of these treatments are relatively new and still to be explored, thus emphasizing the need for an updated review of the literature. In this comprehensive review, we discuss the evaluation of AGA and the mechanisms of action, costs, efficacies, and safety profiles of existing, alternative, and upcoming therapeutics for this widespread condition.

Abstract
Introduction In oral and maxillofacial surgery, hard tissue augmentation is provided by materials that accelerate the healing, act as a template for reconstructing bony defects, and stimulate bone production and growth. This study investigated the effects of biocompatible carriers containing active vitamin D and platelet-rich plasma (PRP) on bone defects created in rat calvaria. Material and Methods This experimental animal study utilized fifty-two male Sprague Dawley rats divided into six groups and conducted histopathological, microtomographic, and biochemical comparisons by adding vitamin D, which has an accelerating effect on bone development. We examined the calvarial defects, sacrificing the rats in equal numbers (eight in each group and four to obtain PRP) at the first, second, fourth, and eighth weeks. The newly formed bone was assessed using histopathologic, microtomographic, and macroscopic methods as well as the biochemical analysis performed in the plasma samples. Expression of fibroblast growth factor 23 (FGF23), vitamin D receptor (VDR), and receptor activator of nuclear factor-kappa B (RANK), which determine bone formation, were investigated. The amounts of ossification, bone volume, and mineral densities were significantly higher in the fourth and eighth weeks as the biocompatible material was delivered with calcitriol. Results The histological and macroscopic examinations revealed that the defect area shrank and was colonized with new cells in the "calcitriol + chitosan + PRP" group. The expression of RANK, FGF23, and VDR antibodies was more intense in the "calcitriol + chitosan + PRP" group than in other groups of the experiment and controls. Conclusion Active vitamin D, PRP, and chitosan formulation positively contributed to the repair of bone defects and induced remarkable clinical improvement. This new delivery approach could be promising for healing bone defects following surgical operations in hard bony tissues. HIPPOKRATIA 2023, 27 (2):48-56.

Abstract
Exosomes isolated from platelet-rich plasma (PRP-exos) have been recently deemed as an optimized therapeutic strategy in Diabetic foot ulcer (DFU) treatment. Herein, we aimed to explore whether MALAT1 participates in DFU wound healing by PRP-exos treatment and the related preliminary mechanism. Fibroblasts were isolated from healthy donors and DFU patients, and the expression of MALAT1, miR-374a-3p and DNMT3A were detected by RT-PCR. The effect of MALAT1 and miR-374a-3p on DFU fibroblast function was verified by gain/loss of function experiment. The targeted binding of MALAT and miRNA was verified by double luciferase reporter gene assay. PRP-exos were isolated from normal human blood and characterized, and then co-cultured with DFU fibroblasts. The MALAT1 expression was donwregulated while the miR-374a-5p expression was upregulated in DFU fibroblasts. Double luciferase reporter gene assay demonstrated the targeted binding of MALAT and miR-374a-5p. Overexpression of MALAT1 or knockdown of miR-374a-5p could increase viability and inhibit apoptosis and pyroptosis of DFU fibroblast. And overexpression of miR-374a-5p reversed the effect of PRR-exos or MALAT1 overexpression on cell viability, apoptosis and pyroptosis. Collectively, MALAT1 mediated signal axis participates in the role of PRP-exos in promoting DFU wound healing, which may help identify optimal targets and effective therapies for DFU treatment.

Abstract
BACKGROUND The aim of our study is to compare the efficacy of PRP, steroids, and autologous blood injection in patients with chronic lateral epicondylitis. METHOD A total of 120 patients comprised our study. Three groups of 40 patients each received only one of the following: PRP, steroids, or autologous blood injections. Thereafter, VAS (visual analog scale), DASH (Disabilities of the Arm, Shoulder, and Hand), and Nirschl scores of those treated were evaluated in the second week, the fourth week, the third month, and the sixth month. RESULTS The baseline evaluation revealed no significant change in VAS, DASH, and Nirschl scores among the three groups (p > 0.050). At the second week evaluation, patients treated with steroids showed significant improvement compared to patients treated with PRP and autologous blood (p < 0.001). The fourth-week evaluation revealed the VAS, DASH, and Nirschl scores of the patients treated with steroids to have improved more significantly than those of patients treated with PRP and autologous blood (p < 0.001). The third month, when the results of all three groups were compared, revealed similar results (p > 0.050). The sixth-month evaluation, when the results of all three groups were compared, revealed the autologous blood and PRP applications provided significantly better results than the group treated with steroids (p < 0.001). CONCLUSION We concluded that steroid administration is effective in the short term, while PRP and autologous blood applications are more effective than steroid administration in the long term.

Abstract
Background and Aims Psychological, behavioral, hormonal, surgical, and psychopharmacologic approaches are the only acknowledged treatments for Female Sexual Dysfunction (FSD). The study is conducted to assess the efficacy of hybrid cooperative complexes of high and low molecular weight hyaluronan (hybrid H-HA/L-HA) in treating females with varying of sexual dysfunction and to assess the female genital self-image scale (FGSIS), female sexual function index (FSFI), and dermatology life quality index (DLQI) before and after treatment. Methods Sixty female patients were divided into two groups. The study group enrolled 30 female patients injected with hybrid H-HA/L-HA, while the control group enrolled 30 female patients injected with saline. Patients were recruited from the clinic searching for medical advice. Controls were selected from close associates of the cases who were attending with the patients or healthy escorts of dermatology patients attending the dermatology outpatient clinic. We assessed socio-demographic, clinical evaluation, the (FGSIS), (FSFI), and (DLQI) before and after treatment. The first assessment was conducted at the first visit, and the second assessment was conducted after 1 month of the second injection. Result Significant increase in the frequency of sexual intercourse/week in the study group after the first and second injection sessions compared to the controls was observed (p < 0.05). There was statistically significant amelioration in desire, arousal, lubrication, orgasm, satisfaction domains, and total score of the FSFI (p ≤ 0.05). The study demonstrated significant increasing differences in all domains of the FGSIS (p ≤ 0.05). The symptoms and feelings, leisure, personal relationships, and total scores were significantly higher post first and second injection of (hybrid H-HA/L-HA) sessions compared to the controls (p < 0.05). Conclusion The (hybrid H-HA/L-HA) injection for rejuvenating the genital area appears to be a safe and effective way to enhance female genital self-image, sexuality, and quality of life with high levels of satisfaction as a minimally invasive method.

Abstract
The platelet-rich plasma (PRP) has become popular in the medical world due to its content of growth factors and numerous studies are experimental. In experimental studies, the preparation and application of PRP are problematic and allogenic PRP transfers have been preffered, because of the difficulties in preparation of autogenic PRP in animal experiments. Xenogenic transfers and their effects have not been studied in this topic. This study aimed to investigate the effect of autogenic and xenogenic use of PRP on composite graft viability.Methods: Two composite grafts are prepared for each ear of nine rabbits. Each ear was randomly divided into three groups. After the procedure, the wound edges and base were injected with 1 cc serum physiologic, autogenic PRP or 1 cc human-derived xenogenic PRP. At 3 weeks, samples were taken, photographic and histopathological evaluations were made.Results: The graft viability was better in autogenic and xenogenic group compared to the control group. In comprasion of autogenic and xenogenic groups, although the macroscopic evaluation revealed better graft viability and less necrosis in the group which had been treated with autogenic PRP, the difference was not statistically significant. The three groups did not significantly differ in terms of inflammation. Vascularization examined histopathologically. CD31 staining, which was used to evaluate angiogenesis, was significantly higher in the autogenic PRP group than the remaining two groups.Conclusion: Although autogenic PRP has better results histopathologically, the xenogenic use of PRP may be an alternative for studies, when macroscopic evaluation is necessary.

Abstract
BACKGROUND Platelet-rich plasma(PRP) and prolotherapy(PRL) are regenerative treatment approaches in the knee osteoarthritis (KOA). AIM To see how efficient PRP and PRL are in treating KOA. METHODS A total of 108 patients with a diagnosis of KOA who received either PRL, PRP, or exercise therapy and whose 3-month follow-up data were available were included in this retrospective study (PRL n = 35 or PRP n = 35, exercise n = 38). Visual Analogue Scale(VAS) and The Western Ontario McMaster University Osteoarthritis Index(WOMAC) were used as outcome measures at baseline, 1 month, and 3 months. RESULTS There were no statistically significant differences between the three groups in terms of demographic parameters, baseline assessments of pain intensity, or WOMAC scores. At the first and third months, all groups showed a substantial improvement in the VAS activity, resting and WOMAC values as compared to before treatment(p < 0.05). When the groups were compared, the VAS activity, resting, and WOMAC values in PRP and PRL improved significantly in the first and third months compared to the exercise group. At one month, there was a statistically significant improvement in VAS activity and WOMAC pain and total scores compared to PRP and PRL, but this improvement was not significant at 3 months. CONCLUSION Pain and disability were significantly improved with PRL and PRP compared with exercise therapy. Although PRP is more effective than PRL in the first month after treatment, PRL may be preferred due to its low cost, long-term efficacy, and low complication rates due to the periarticular application.

Abstract
Fertility preservation is one of the most important issues in assisted reproductive technology. Previous studies have shown that cytokines and growth factors can improve follicle growth. The endometrial stromal cells secrete various factors that are involved in maintaining the integrity of uterine and epithelial secretory function. The platelet-rich plasma contains a large assembly of platelets suspended in plasma that successfully improves the viability and growth of various cell lines. This work aimed to investigate the influences of conditioned medium (CM) and platelet-rich plasma (PRP) on the development of ovarian follicles in infertile mice due to cyclophosphamide (CYC) exposure. In this study, 65 healthy BALB/c female mice (∼28-30 g and 6-8 weeks old) in five groups were studied. Immunohistochemistry (IHC) was used to detect growth differentiation factor 9 (GDF9)-positive cells. The mRNA expression levels of SMAD1, SMAD2, and BMP15 was assessed using reverse transcription-polymerase chain reaction (RT-PCR) method. The expression levels of SMAD1, GDF9, BMP15, and SMAD2 in the CM+PRP group was significantly more than in the CM and PRP groups. In addition, live birth occurred in the CM+PRP group. Treatment with CM+PRP in infertile mice due to Cy exposure increased fertility and live-birth rate. In general, our study suggested that the CM and PRP combination could improve the growth of mice ovarian follicles in vivo.

Abstract
BACKGROUND Platelet lysate (PL) is considered as an alternative to fetal bovine serum (FBS) and facilitates the proliferation and differentiation of mesenchymal cells. OBJECTIVE The aim of this study is to explore whether super activated platelet lysate (sPL), a novel autologous platelet lysate, has the ability to inhibit inflammation and promote cell proliferation, repair and osteogenesis as a culture medium. METHODS Different concentrations of sPL on human fetal osteoblastic 1.19 cell line (hFOB1.19) proliferation and apoptotic repair were investigated; And detected proliferative capacity, inflammatory factor expressions and osteogenic differentiation of human dental pulp cells (hDPCs) stimulated by LPS under 10% FBS and 5% sPL mediums. RESULTS sPL promoted hFOB1.19 proliferation and had repairing effects on apoptotic cells. No significant difference in proliferation and IL-1α, IL-6 and TNF-α expressions of hDPCs in FBS and sPL medium stimulated by LPS. hDPCs in sPL osteogenic medium had higher osteogenic-related factor expressions and ALP activity. LPS promoted osteogenic-related factor expressions and ALP activity of hDPCs in FBS osteogenic medium, but opposite effect showed in sPL medium. CONCLUSION sPL promoted osteoblast proliferation and had restorative effects. Under LPS stimulation, sPL did not promote hDPCs proliferation or inhibit inflammation. sPL promotes osteogenic differentiation of hDPCs.

Abstract
Osteoarthritis (OA) is the most common progressive condition affecting joints. It mainly affects the knees and hips as predominant weight-bearing joints. Knee osteoarthritis (KOA) accounts for a large proportion of osteoarthritis and presents numerous symptoms that impair quality of life, such as stiffness, pain, dysfunction, and even deformity. For more than two decades, intra-articular (IA) treatment options for managing knee osteoarthritis have included analgesics, hyaluronic acid (HA), corticosteroids, and some unproven alternative therapies. Before effective disease-modifying treatments for knee osteoarthritis, treatments are primarily symptomatic, mainly including intra-articular corticosteroids and hyaluronic acid, so these agents represent the most frequently used class of drugs for managing knee osteoarthritis. But research suggests other factors, such as the placebo effect, have an essential role in the effectiveness of these drugs. Several novel intra-articular therapies are currently in the clinical trial processes, such as biological therapies, gene and cell therapies. Besides, it has been shown that the development of novel drug nanocarriers and delivery systems could improve the effectiveness of therapeutic agents in osteoarthritis. This review discusses the various treatment methods and delivery systems for knee osteoarthritis and the new agents that have been introduced or are in development.

Abstract
Purpose: Carpal tunnel syndrome (CTS) is a common form of median nerve compression in the wrist caused by focal peripheral neuropathy. Platelet-rich plasma (PRP) therapy could improve the healing ability by exposing the injured tissues to high concentrations of autologous growth factors. Our study aims to compare all injective treatments for CTS and assess the efficacy and priority of PRP therapy. Methods: We searched Medline, Embase, Web of Science, Cochrane databases, and Clinicaltrial.gov until 17 October 2022. We only included data from randomized controlled trials (RCTs) that evaluated PRP injection therapy or drug injection therapy. The included RCTs measured at least one of the following three outcomes with validated instruments: in the visual analog scale (VAS), symptom severity scale (SSS), and functional status scale (FSS). Results: Overall, 19 studies with 1,066 patients were included in this study. We used the SUCRA rankings to determine the merits of various therapies. In all, 5% dextrose injections were the best treatment strategy for the VAS (MD -1.22, 95% CI -2.66 to 0.23; SUCRA = 79.2%), followed by triamcinolone (high-dose) injections (MD -0.69, 95% CI -2.11 to 0.73; SUCRA = 62.7%) and PRP injections (MD -0.39, 95% CI -1.67 to 0.89; SUCRA = 60.0%). In the SSS, the most effective intervention was hydroxyprogesterone injections (MD -0.62, 95% CI -1.09 to -0.16; SUCRA = 91.0%). The SUCRA ranking of PRP was second only to steroids and estrogen (MD -0.39, 95% CI -0.60 to -0.18; SUCRA = 60.8%). In the FSS, the best regimen strategy was hydroxyprogesterone injections (MD 0.12, 95% CI -0.30 to 0.54; SUCRA = 99.5%), followed by triamcinolone (low-dose) injections (MD -0.02, 95% CI -0.54 to 0.49; SUCRA = 87.4%) and PRP injections (MD -0.26, 95% CI -0.43 to -0.09; SUCRA = 77.1%). Conclusion: PRP is an alternative choice for CTS treatment. PRP injection is second only to steroids and estrogen in the treatment efficacy of CTS, with a wide indication and safe outcome.

Abstract
Atherosclerosis (AS), the main cause of many cardiovascular diseases (CVDs), is a progressive inflammatory disease characterized by the accumulation of lipids, fibrous elements, and calcification in the innermost layers of arteries. The result is the thickening and clogging of these vessel walls. Several cell types are directly involved in the pathological progression of AS. Among them, platelets represent the link between AS, inflammation, and thrombosis. Indeed, besides their pivotal role in hemostasis and thrombosis, platelets are key mediators of inflammation at injury sites, where they act by regulating the function of other blood and vascular cell types, including endothelial cells (ECs), leukocytes, and vascular smooth muscle cells (VSMCs). In recent years, increasing evidence has pointed to a central role of platelet-derived extracellular vesicles (P-EVs) in the modulation of AS pathogenesis. However, while the role of platelet-derived microparticles (P-MPs) has been significantly investigated in recent years, the same cannot be said for platelet-derived exosomes (P-EXOs). For this reason, this reviews aims at summarizing the isolation methods and biological characteristics of P-EXOs, and at discussing their involvement in intercellular communication in the pathogenesis of AS. Evidence showing how P-EXOs and their cargo can be used as biomarkers for AS is also presented in this review.

Abstract
Platelet-rich plasma injections have been a therapeutic option with exponential growth in several pathologies in the last decades, particularly musculoskeletal for their effect on improving pain and functionality. Rheumatoid arthritis is a chronic joint disease, which involves inflammation of the synovial membrane with cartilage and juxta-articular bone destruction. Conventional and biological disease-modifying anti-rheumatoid drugs are the cornerstone of the treatment of this disease. However, the use of intra-articular glucocorticoids is often necessary and the role of platelet-rich plasma injections in these patients remains uncertain. A literature review was carried out through the PubMed database, Cochrane and Google Scholar for the search terms “rheumatoid arthritis” and “platelet-rich plasma”. Eleven studies have been included in this review: two of these are in vitro studies, five are animal studies, one case report, two case series and one randomized controlled trial. Most of the studies demonstrated a decrease in pain and inflammatory mediators and improvement of functional outcomes, with no severe adverse effects reported. However, the quantity and quality of literature about the effects and safety of plasma-rich plasma injections in rheumatoid arthritis patients are still scarce. It is essential that well-designed randomized controlled trials are made on this topic to understand if platelet-rich plasma may be useful as a coadjuvant therapy in rheumatoid arthritis.

Abstract
Musculoskeletal pain is the most common pain reported by patients. Platelet-rich plasma (PRP) is widely used to treat musculoskeletal pain. However, the efficacy of PRP to treat this pain remains controversial. This review highlights the application of PRP in the treatment of musculoskeletal pain. PRP treatment appears to reduce pain and improve function in patients with musculoskeletal pain. However, there are limitations to the currently published studies. These limitations include the PRP preparation methods, type of activators, types of pathology to be treated, methods and times of administration, and association of PRP with other treatments.

Abstract
BACKGROUND The evaluation of the efficacy of platelet-rich plasma (PRP) in clinical practice yields conflicting results and raises numerous controversies. This may be due to different concentrations of biologically active components in PRP obtained with the use of different methods of gravity separation.
AIM To compare the content, repeatability and correlations between biologically active components in PRP obtained with four different commercial systems.
METHODS From a whole blood sample of each of 12 healthy male volunteers, 4 PRP samples were prepared using 4 different commercial kits [Arthrex Autologous Conditioned Plasma (ACP), Mini GPS III, Xerthra, Dr. PRP] in accordance with the instructions provided by the manufacturers. A comparative analysis of blood cell components - 13 selected inflammatory cytokines and 7 growth factors - in the obtained PRP samples was performed using the Kruskal-Wallis test by ranks. The repeatability of results in each method was evaluated by the estimation of the coefficient of variation. The Spearman correlation was used to estimate the relationship between blood cell content and cytokines.
RESULTS Significantly higher concentrations of platelets (PLT), white blood cells (WBC) and red blood cells (RBC) were found in PRP obtained with the use of Mini GPS III than in PRP obtained using other systems. Significant differences in the content of growth factors and cytokines in PRP were found. A positive correlation of the amount of PLT, RBC and WBC with the concentration of most of the growth factors was found but in only three inflammatory cytokines. The obtained correlations between blood cell components and cytokines differed between the systems in terms of statistical significance, which may be due to insufficient sample size. The repeatability of the obtained PLT concentration also varied between protocols with the lowest in Xerthra and the highest in Arthrex ACP.
CONCLUSION Significant differences in the content of biologically active components and their repeatability were found in PRP obtained by various methods, providing new data for further research.

Abstract
Background Acute skin wounds may compromise the skin barrier, posing a risk of infection. Small intestinal submucosa (SIS) is widely used to treat acute and chronic wounds. However, the efficacy of SIS to accelerate wound healing still needs to be improved to meet clinical demands. To tackle this problem, platelet-rich plasma (PRP) is used due to its potency to promote proliferation, migration and adhesion of target cells. In this study, we applied PRP and SIS to skin wounds to explore their effects on wound healing by evaluating re-epithelialization, collagen production, angiogenesis and the inflammatory response. Methods A 1 × 1-cm full-thickness skin defect was established in mice. Sixty mice were divided into four treatment groups: PRP + SIS, PRP, SIS and control. On days 3, 5, 7, 10 and 14 post-surgery, tissue specimens were harvested. Haematoxylin and eosin, Masson's trichrome, immunohistochemical and immunofluorescence double staining were used to visualize epidermal thickness, collagen and vascular regeneration and inflammation. Results Wound contraction in the PRP and PRP + SIS groups was significantly greater, compared with the other groups, on days 3 and 5 post-surgery. A histological analysis showed higher collagen expression in the PRP and PRP + SIS groups on day 7, which was associated with a thicker epidermal layer on day 14. In addition, immunohistochemical staining showed that CD31-positive blood vessels and vascular endothelial growth factor expression in the PRP + SIS and PRP groups were significantly higher, compared with the control group. Furthermore, immunofluorescence double staining showed that the number of M1 and M2 macrophages in the PRP + SIS and PRP groups was higher, compared with the control and SIS groups alone, on day 3. However, on day 7, the number of M1 macrophages dramatically decreased in the PRP + SIS and PRP groups. The ratio of M2 to M1 macrophages in the PRP + SIS and PRP groups was 3.97 and 2.93 times that of the control group and 4.56 and 3.37 times that of the SIS group, respectively. Conclusion Co-administration of SIS and PRP has a better effect on promoting angiogenesis, re-epithelialization and collagen regeneration in managing acute wound healing than either agent alone.

Abstract
Intrauterine adhesion (IUA) is caused by artificial endometrial damage during intrauterine cavity surgery. The typical phenotype involves loss of spontaneous endometrium recovery and angiogenesis. Undesirable symptoms include abnormal menstruation and infertility; therefore, prevention and early treatment of IUA remain crucial issues. Extracorporeal shockwave therapy (ESWT) major proposed therapeutic mechanisms include neovascularization, tissue regeneration, and fibrosis. We examined the effects of ESWT and/or platelet-rich plasma (PRP) during preventive and therapeutic stages of IUA by inducing intrauterine mechanical injury in rats. PRP alone, or combined with ESWT, were detected an increased number of endometrial glands, elevated vascular endothelial growth factor protein expression (hematoxylin-eosin staining and immunohistochemistry), and reduced fibrosis rate (Masson trichrome staining). mRNA expression levels of nuclear factor-kappa B, tumor necrosis factor-α, transforming growth factor-β, interleukin (IL)-6, collagen type I alpha 1, and fibronectin were reduced during two stages. However, PRP alone, or ESWT combined with PRP transplantation, not only increased the mRNA levels of vascular endothelial growth factor (VEGF) and progesterone receptor (PR) during the preventive stage but also increased PR, insulin-like growth factor 1 (IGF-1), and IL-4 during the therapeutic stage. These findings revealed that these two treatments inhibited endometrial fibrosis and inflammatory markers, thereby inhibiting the occurrence and development of intrauterine adhesions.

Abstract
AbstractSubtalar osteoarthritis (STOA) is often secondary to chronic ankle sprains, which seriously affects the quality of life of patients. Due to its etiology and pathogenesis was not studied equivocally yet, there is currently a lack of effective conservative treatments. Although they have been used for tissue repair, platelet-rich plasma-derived exosomes (PRP-Exo) have the disadvantage of low retention and short-lived therapeutic effects. This study aimed to determine whether incorporation of PRP-Exo in thermosensitive hydrogel (Gel) increased their retention in the joint and thereby playing a therapeutic role on STOA due to chronic mechanical instability established by transecting lateral ligaments (anterior talofibular ligament (ATFL)/calcaneal fibular ligament (CFL)). PRP-Exo incorporated Gel (Exo-Gel) system, composed of Poloxamer-407 and 188 mixture-based thermoresponsive hydrogel matrix in an optimal ratio, was determined by its release ability of Exo and rheology of Gel response to different temperature. The biological activity of Exo-Gel was evaluated in vitro, and the therapeutic effect of Exo-Gel on STOA was evaluated in vivo. Exo released from Exo-Gel continuously for 28 days could promote the proliferation and migration of mouse bone mesenchymal stem cells (mBMSCs) and chondrocytes, at the same time enhance the chondrogenic differentiation of mBMSCs, and inhibit inflammation-induced chondrocyte degeneration. In vivo experiments confirmed that Exo-Gel increased the local retention of Exo, inhibited the apoptosis and hypertrophy of chondrocytes, enhanced their proliferation, and potentially played the role in stem cell recruitment to delay the development of STOA. Thus, Delivery of PRP-Exo incorporated in thermosensitive Gel provides a novel approach of cell-free therapy and has therapeutic effect on STOA.

Abstract
Clitoral reconstruction after female genital mutilation/cutting (FGM/C) is associated with significant post-operative pain and months-long recovery. Autologous platelet-rich plasma (A-PRP) reduces the time of healing and pain in orthopedic and burn patients and could also do so in clitoral reconstruction. In the present case, a 35-year-old Guinean woman who had undergone FGM/C Type IIb presented to our clinic for clitoral reconstruction. Her request was motivated by low sexual satisfaction and body image. We surgically reconstructed the clitoris using the Foldès method and applied plasma and glue of A-PRP. The patient was highly satisfied with the procedure. Two months post-operatively, her pain had ceased entirely and re-epithelialization was complete. We conclude that A-PRP may improve pain and healing after clitoral reconstruction. Extensive studies investigating long-term outcomes are needed.

Abstract
Local anesthetics are often used at the site of injury or mixed with platelet-rich plasma to reduce pain when treating orthopedic and sports-related injuries. Local anesthetics have been shown to have deleterious effects on stromal cells, but their impact on platelets has not been investigated. In this study, we aimed to assess the effects of lidocaine, bupivacaine, and ropivacaine on platelet health. Based on the deleterious effects of local anesthetics on nucleated cells, we hypothesized that these compounds would affect platelet viability, intracellular physiology, and function. Platelet preparations were derived from randomly selected donors and exposed to lidocaine 1%, bupivacaine 0.75%, ropivacaine 0.5%, and saline at 1:1 and 1:3 ratios. Platelet morphology, viability, intracellular calcium, production of radical oxygen species (ROS), apoptosis, and adhesion were assessed via fluorescent microscopy and flow cytometry. Bupivacaine resulted in increased ROS production, calcium dysregulation, apoptosis, and reduced platelet adhesion. By contrast, ropivacaine and lidocaine were similar to saline in most assays, except for a low degree of mitochondrial stress as evidenced by increased ROS production. Ultimately, bupivacaine 0.75% was harmful to platelets as evidenced by reduced platelet viability, adhesion, and increased apoptosis, whereas lidocaine 1% and ropivacaine 0.5% were relatively safe at the 1:1 and 1:3 dilutions. Clinical significance: Lidocaine 1% and ropivacaine 0.5% can be used at up to a 1:1 ratio with platelet preparations to reduce the pain and discomfort of PRP procedures while maintaining platelet therapeutic potential.

Abstract
The treatment of rheumatoid arthritis (RA) has been closely evolving with an understanding of disease pathogenesis with disease modifying anti-rheumatoid drugs (DMARDS) and Biologic DMARDS being the main stay. platelet rich plasma (PRP) has been the center of research in many specialties in the past decade. Its ability to stop and reverse inflammation have attracted researchers to try PRP in RA. A systematic review of studies on PRP in RA is lacking. The study protocol was prospectively registered in PROSPERO. Detailed search of Cochrane, Scopus, Medline, Embase, and Web of science databases were made to identify the relevant articles till Sep 2020 following Cochrane and PRISMA guidelines. Number of subjects, Animal model used, cell lines used for the study, method of induction of arthritis, PRP dose, concentration used, frequency of administration and clinical, histologic, and molecular changes from baseline following PRP use were extracted and analysed. Eight studies were included for the review. Four of these were in-vitro studies. Two were exclusive animal studies. One study analysed the effects of PRP in RA in both animal models (mice) and Hela cell lines. One study was a report of a series of patients of resistant RA treated with PRP. In the in vitro studies while platelets increase the migration and invasion of RA-FLS, they suppressed the inflammation on the whole. Available animal studies and the Human study have shown encouraging results. There has been no evidence of exacerbation of inflammation in these studies. The quantity and quality of literature on the effects of PRP in treating joint pathologies in RA is limited. Preclinical studies show decrease in disease activity with good safety profile. Invitro studies show suppression of inflammation. Thus, the available literature is encouraging towards the use of PRP in RA. Larger trials and molecular studies to understand the exact role of platelets in disease pathogenesis and treatment mechanisms are needed to decide the future course of PRP in RA.

Abstract
To induce bone regeneration there is a complex cascade of growth factors. Growth factors such as recombinant BMP-2, BMP-7, and PDGF are FDA-approved therapies in bone regeneration. Although, BMP shows promising results as being an alternative to autograft, it also has its own downfalls. BMP-2 has many adverse effects such as inflammatory complications such as massive soft-tissue swelling that can compromise a patient's airway, ectopic bone formation, and tumor formation. BMP-2 may also be advantageous for patients not willing to give up smoking as it shows bone regeneration success with smokers. BMP-7 is no longer an option for bone regeneration as it has withdrawn off the market. PDGF-BB grafts in studies have shown PDGF had similar fusion rates to autologous grafts and fewer adverse effects. There is also an FDA-approved bioactive molecule for bone regeneration, a peptide P-15. P-15 was found to be effective, safe, and have similar outcomes to autograft at 2 years post-op for cervical radiculopathy due to cervical degenerative disc disease. Growth factors and bioactive molecules show some promising results in bone regeneration, although more research is needed to avoid their adverse effects and learn about the long-term effects of these therapies. There is a need of a bone regeneration method of similar quality of an autograft that is osteoconductive, osteoinductive, and osteogenic. This review covers all FDA-approved bone regeneration therapies such as the "gold standard" autografts, allografts, synthetic bone grafts, and the newer growth factors/bioactive molecules. It also covers international bone grafts not yet approved in the United States and upcoming technologies in bone grafts.

Int J Mol Sci 2021; 22:11553. [PMID: 34768984 PMCID: PMC8583771 DOI: 10.3390/ijms222111553] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 10/18/2021] [Accepted: 10/18/2021] [Indexed: 01/02/2023] Open
Abstract
The purpose of this review is to examine the latest literature on the use of autologous platelet-rich fibrin as a drug and growth factor carrier system in maxillofacial surgery. Autologous platelet-rich fibrin (PRF) is a unique system that combines properties such as biocompatibility and biodegradability, in addition to containing growth factors and peptides that provide tissue regeneration. This opens up new horizons for the use of all beneficial ingredients in the blood sample for biomedical purposes. By itself, PRF has an unstable effect on osteogenesis: therefore, advanced approaches, including the combination of PRF with materials or drugs, are of great interest in clinics. The main advantage of drug delivery systems is that by controlling drug release, high drug concentrations locally and fewer side effects within other tissue can be achieved. This is especially important in tissues with limited blood supply, such as bone tissue compared to soft tissue. The ability of PRF to degrade naturally is considered an advantage for its use as a "warehouse" of controlled drug release systems. We are focusing on this concentrate, as it is easy to use in manipulations and can be delivered directly to the surgical site. The target audience for this review are researchers and medical doctors who are involved in the development and research of PRFs further studies. Likewise, surgeons who use PRF in their work to treat patients and who advice patients to take the medicine orally.
