[PMID: 38533823 DOI: 10.1002/jbm.b.35399] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 02/08/2024] [Accepted: 02/19/2024] [Indexed: 03/28/2024]
Abstract
Deep skin burn represents a global morbidity and mortality problem, and the limitation of topical treatment agents has motivated research to development new formulations capable of preventing infections and accelerating healing. The aim of this work was to develop and characterize an emulgel based on collagen (COL) and gelatin (GEL) extracted from fish skin associated with Chlorella vulgaris extract (CE) and silver nitrate (AgNO3). COL and GEL were characterized by physicochemical and thermal analyses; and CE by electrophoresis and its antioxidant capacity. Three emulgels formulations were developed: COL (0.5%) + GEL (2.5%) (E1), COL+GEL+CE (1%) (E2), and COL+GEL+CE + AgNO3 (0.1%) (E3). All formulations were characterized by physicochemical, rheology assays, and preclinical analyses: cytotoxicity (in vitro) and healing potential using a burn model in rats. COL and GEL showed typical physicochemical characteristics, and CE presented 1.3 mg/mL of proteins and antioxidant activity of 76%. Emulgels presented a coherent physicochemical profile and pseudoplastic behavior. Preclinical analysis showed concentration-dependent cytotoxicity against fibroblast and keratinocytes. In addition, all emulgels induced similar percentages of wound contraction and complete wound closure in 28 days. The histopathological analysis showed higher scores for polymorphonuclear cells to E1 and greater neovascularization and re-epithelialization to E3. Then, E3 formulation has potential to improve burn healing, although its use in a clinical setting requires further studies.

Abstract
The introduction of fish skin as a biological dressing for treating burns and wounds holds great promise, offering an alternative to existing management strategies. However, the risk of disease transmission is a significant concern. Therefore, this study aimed to examine how established sterilization and preservation procedures affected fish skin grafts' microbiological and histological properties for long-term usage. Lyophilization of the fish skin graft followed by rehydration in normal saline for 15 min did not change the collagen content. Furthermore, gamma irradiation of the lyophilized fish skin graft at different lengths 5, 10, and 25 KGy showed a significant reduction in microbial growth (aerobic bacteria, aerobic yeasts, and fungi) at 15- and 30 days after the irradiation. However, exposure to 10 KGy was found to be the most effective intensity among the different gamma irradiation lengths since it preserved the collagen fiber content and intensity in the lyophilized fish skin grafts at 15- and 30 days after the irradiation. These findings provide efficient preservation and sterilization methods for long-term usage of the fresh Tilapia skin grafts used for biological dressings.

The clinical outcomes of xenografts in the treatment of burn patients: a systematic review and meta-analysis. Eur J Med Res 2023; 28:524. [PMID: 37974238 PMCID: PMC10652578 DOI: 10.1186/s40001-023-01505-9] [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: 05/13/2023] [Accepted: 11/04/2023] [Indexed: 11/19/2023] Open
Abstract
BACKGROUND Although autografts are not feasible in patients with extensive burn wounds, allografts and xenografts can be used for temporary coverage. In this systematic review and meta-analysis, we compared the outcomes of xenografts and the standard treatment of burn wounds. METHODS International online databases were searched for English articles comparing xenografts with routine treatment in the burn patients. The random-effects model was used to estimate standardized mean differences (SMD) or odds ratios (OR) with a 95% confidence interval (CI). RESULTS From a total of 7144 records, 14 studies were included in our review after screening by title and abstracts followed by full-texts. No significant difference in hospital stays was found between the mammalian xenografts and control groups (SMD [95% CI] = - 0.18 [- 0.54-0.18]). The mean number of dressing changes was significantly lower in both mammalian xenografts compared to the controls (SMD [95% CI] = - 1.01 [- 1.61-- 0.41]) and fish xenografts compared to controls (SMD [95% CI] = - 6.16 [- 7.65-- 4.66]). In the fish xenografts, re-epithelialization time was significantly lower compared to controls (SMD [95% CI] = - 1.18 [- 2.23-- 0.14]). CONCLUSIONS Xenografts showed a significantly lower number of dressing changes and fish xenografts showed significant benefit in re-epithelialization compared to routine treatment. The beneficial results of xenografts suggest further research in the use of different types of xenografts in patients with extensive burn.

Abstract
OBJECTIVES To study the clinical, cytological, and vaginal microbiota findings in patients with Mayer-Rokitansky-Küster-Hauser syndrome who underwent neovaginoplasty using Nile tilapia fish skin. METHODS This is a cross-sectional study with 7 cisgender women with Mayer-Rokitansky-Küster-Hauser syndrome who had previously undergone neovagina reconstruction using Nile tilapia fish skin at a university hospital. Local institutional review board approval and written permission from the patient were obtained. Between August 2019 and November 2021, within 12 to 24 months after surgery, vaginal specimens were obtained for conventional oncotic and hormonal cytology, and for Gram staining. The Nugent scores were calculated. Colposcopy was also performed. RESULTS Squamous cells without atypia were found in all patients. Five patients had intermediate vaginal microbiota (Nugent score of 4), which was determined by the presence of few lactobacilli on Gram staining. In hormonal cytology, 4 patients presented with findings compatible with menacme. No colposcopic change was observed. When postsurgical dilation was performed correctly, a mean vaginal length of 8.3 cm was maintained after 1 year of follow-up. CONCLUSIONS Squamous cells without atypia were present in neovaginas with Nile tilapia fish skin. Most vaginal contents revealed intermediate microbiota and hormonal results compatible with menacme. Studies with a greater number of patients are necessary for a more comprehensive understanding of the microbiome in neovaginas with this new technique, thereby providing support for the treatment and prevention of associated pathologies.

Comparison of Type I and Type III Collagen Concentration between Oreochromis mossambicus and Oreochromis niloticus in Relation to Skin Scaffolding. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1002. [PMID: 37374206 DOI: 10.3390/medicina59061002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 05/11/2023] [Accepted: 05/22/2023] [Indexed: 06/29/2023]
Abstract
Background and Objectives: Skin scaffolding can be done using allografts and autografts. As a biological allograft, the skin of Oreochromis niloticus (ON) has been used due to its high type I and III collagen content. Oreochromis mossambicus (OM) is also a member of the Oreochromis family, but not much is known regarding its collagen content. As such, this study aimed to assess and compare the collagen content of the two fish species. Materials and Methods: This is a crossover study comparing the skin collagen contents of the two fish. Young fish were chosen, as they tend to have higher collagen concentrations. The skin samples were sterilized in chlorhexidine and increasing glycerol solutions and analyzed histochemically with Sirius red picrate under polarized light microscopy. Results: 6 young ON and 4 OM specimens were used. Baseline type I collagen was higher for OM, but at maximum sterilization it was higher for ON, with no differences in between Type III collagen was higher for OM across all comparisons with the exception of the last stage of sterilization. Generally, collagen concentrations were higher in highly sterilized samples. Conclusions: OM skin harvested from young fish, with its greater collagen III content may be a better candidate for use as a biological skin scaffold in the treatment of burn wounds, compared to ON.

From ecological functions to ecosystem services: linking coastal lagoons biodiversity with human well-being. HYDROBIOLOGIA 2023; 850:2611-2653.

Abstract
In this review we highlight the relevance of biodiversity that inhabit coastal lagoons, emphasizing how species functions foster processes and services associated with this ecosystem. We identified 26 ecosystem services underpinned by ecological functions performed by bacteria and other microbial organisms, zooplankton, polychaetae worms, mollusks, macro-crustaceans, fishes, birds, and aquatic mammals. These groups present high functional redundancy but perform complementary functions that result in distinct ecosystem processes. Because coastal lagoons are located in the interface between freshwater, marine and terrestrial ecosystems, the ecosystem services provided by the biodiversity surpass the lagoon itself and benefit society in a wider spatial and historical context. The species loss in coastal lagoons due to multiple human-driven impacts affects the ecosystem functioning, influencing negatively the provision of all categories of services (i.e., supporting, regulating, provisioning and cultural). Because animals' assemblages have unequal spatial and temporal distribution in coastal lagoons, it is necessary to adopt ecosystem-level management plans to protect habitat heterogeneity and its biodiversity, ensuring the provision of services for human well-being to multi-actors in the coastal zone.

Age-Related Properties of Aquaponics-Derived Tilapia Skin ( Oreochromis niloticus): A Structural and Compositional Study. Int J Mol Sci 2023; 24:ijms24031938.

Abstract
In the last two decades, fisheries and fish industries by-products have started to be recovered for the extraction of type I collagen because of issues related to the extraction of traditional mammalian tissues. In this work, special attention has been paid to by-products from fish bred in aquaponic plants. The valorization of aquaponic fish wastes as sources of biopolymers would make the derived materials eco-friendlier and attractive in terms of profitability and cost effectiveness. Among fish species, Nile Tilapia is the second-most farmed species in the world and its skin is commonly chosen as a collagen extraction source. However, to the best of our knowledge, no studies have been carried out to investigate, in depth, the age-related differences in fish skin with the final aim of selecting the most advantageous fish size for collagen extraction. In this work, the impact of age on the structural and compositional properties of Tilapia skin was evaluated with the aim of selecting the condition that best lends itself to the extraction of type I collagen for biomedical applications, based on the known fact that the properties of the original tissue have a significant impact on those of the final product. Performed analysis showed statistically significant age-related differences. In particular, an increase in skin thickness (+110 µm) and of wavy-like collagen fiber bundle diameter (+3 µm) besides their organization variation was observed with age. Additionally, a preferred collagen molecule orientation along two specific directions was revealed, with a higher fiber orientation degree according to age. Thermal analysis registered a shift of the endothermic peak (+1.7 °C) and an increase in the enthalpy (+3.3 J/g), while mechanical properties were found to be anisotropic, with an age-dependent brittle behavior. Water (+13%) and ash (+0.6%) contents were found to be directly proportional with age, as opposed to protein (-8%) and lipid (-10%) contents. The amino acid composition revealed a decrease in the valine, leucine, isoleucine, and threonine content and an increase in proline and hydroxyproline. Lastly, fatty acids C14:0, C15:0, C16:1, C18:2n6c, C18:3n6, C18:0, C20:3n3, and C23:0 were revealed to be upregulated, while C18:1n9c was downregulated with age.

Photoprotective Efficacy of the Association of Rosmarinic Acid 0.1% with Ethylhexyl Methoxycinnamate and Avobenzone. COSMETICS 2023.

Abstract
Innovative prototype sunscreens with reduced ultraviolet (UV) filters are required to achieve safer, more effective, and more environmentally friendly formulations. Rosmarinic acid (RA) is a phenolic antioxidant and potential candidate for multifunctional sunscreens. We used RA (0.1% w/w) in combination with avobenzone (2.5% and 5.0% w/w), a UVA filter, and ethylhexyl methoxycinnamate (10.0% w/w), a UVB filter, to evaluate in vitro sun protection factor (SPF) and critical wavelength, photostability, and the in vivo SPF. RA, in vitro, improved the SPF of F2 (ethylhexyl methoxycinnamate 10.0% w/w + avobenzone 2.5% w/w + RA 0.1% w/w) and F3 (ethylhexyl methoxycinnamate 10.0% w/w + avobenzone 5.0% w/w + RA 0.1% w/w), which also presented broad-spectrum profiles; however, no expressive effects were observed for the critical wavelength (nm). By the in vivo trial, RA showed an increment in the F3 SPF value and maintained the F2 effectiveness, even when avobenzone was at 2.5%. Nonetheless, no increase in photostability was observed. Our findings suggest that incorporating natural molecules with antioxidant activities into sunscreens could decrease the proportion of conventional UV filters in the final product, with the advantage of providing other functional properties. Further investigation of higher RA concentrations, even from other sources, and other UV filter combinations could reveal important data for the development of multifunctional sunscreens.

The optimal concentration of silver nanoparticles in sterilizing fish skin grafts. Sci Rep 2022; 12:19483. [PMID: 36376399 PMCID: PMC9663429 DOI: 10.1038/s41598-022-23853-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Accepted: 11/07/2022] [Indexed: 11/16/2022] Open
Abstract
Collagen integrity should be considered on using a sterilizing agent for fish skin grafts. This study defined the optimal concentration of silver nanoparticles (Ag NPs) for sterilization of fish skin grafts without disrupting collagen content based on microbiological and histological evaluation. Strips of tilapia skin (n = 5) were randomly allocated to be immersed in Ag NPs solution at different concentrations of 25, 50, 100, and 250 µg/mL, respectively, for 5 min. The treated skin strips underwent bacteriological and histological evaluation. Yeast and fungi were more sensitive to Ag NPs than bacteria. On increasing the nanoparticles concentration, the total counts of aerobic bacteria decrease giving 933.3 ± 28.67, 601 ± 27.66, 288 ± 16.8, 15 ± 4.08 (CFU/cm2 ± S.D) at 25, 50, 100, and 250 µg/mL, respectively, comparing with untreated sample (1453.3 ± 57.92). Yeasts and filamentous fungi also exhibited a similar response, achieving a complete inhibition at 100 and 250 µg/mL. Bacillus cereus and Escherichia coli were the dominant aerobic bacteria, Candida albicans and Rhodotorula glutinis were the dominant aerobic yeasts, whereas Aspergillus niger, Aspergillus fumigatus, and Rhizopus stolonifer were the dominant aerobic fungi. The collagen fibers were loose with a wavey pattern at 25 µg/mL, wavey and slightly disorganized at 50 µg/mL, highly disorganized at 100 µg/mL, and compactly arranged and slightly loose at 250 µg/mL. Ag NPs at a concentration of 250 µg/mL could be considered a reliable and feasible method for the sterilization of fish skin grafts before application on human skin with an effective antimicrobial effect and less disrupting impact on collagen content.

Abstract
Management of wounds is a commonly performed and essential aspect of small animal veterinary medicine. Appropriate wound management is a difficult art to master, due to the inherent complexity of the clinical scenario, as well as the ever-evolving nature of the field with the constant addition of new products and techniques. This article reviews key concepts that may help the practitioner better understand the natural process of wound healing, factors that delay healing and strategies to help improve the local wound environment to make it more conducive to healing during open wound management. The concept of wound bed preparation is defined before common local wound management strategies, such as wound lavage and debridement, are discussed in more detail. Key aspects of the management of biofilms and appropriate use of antimicrobial agents are also reviewed. Finally, the concept of moist wound healing and its impact in modern wound management is explained before a broad variety of types of wound dressings are reviewed, with a particular focus on active dressings.

Abstract
Acellular skin as a scaffold has a good potential to regenerate or repair damaged tissues. Growth factors such as Plasma Rich in Growth Factor (PRGF) as a rich source of active proteins can accelerate tissue regeneration. In this study, an acellular scaffold derived from fish skin with growth factors was used to repair full-thickness skin defects in a rat model. Cellular results demonstrated that epithelial cells adhere well to acellular scaffolds. The results of animal studies showed that the groups treated with acellular scaffold and growth factor have a high ability to close and heal wounds on the 28th day after surgery. Histological and staining results showed that in the treated groups with scaffold and growth factor, an epidermal layer was formed with some skin appendages similar to normal skin. Overall, such scaffolds with biological agents can cause an acceptable synergistic effect on skin regeneration and wound healing.

Abstract
INTRODUCTION AND HYPOTHESIS Mayer-Rokitansky-Küster-Hauser syndrome affects about 1 in 5000 live female births and is associated with gonadal dysgenesis and primary amenorrhea. Neovaginoplasty has been established as an appropriate treatment option for patients who have failed or denied dilation therapy. In search of accessible, economical material with low risk of complications, the team proposed the use of Nile tilapia fish skin (NTFS) as an innovative biomaterial in the neovaginoplasty procedure for vaginal agenesis management. NTFS has noninfectious microbiota, morphologic structure comparable to human skin and high in vivo bioresorption. METHODS In this descriptive study, the method offered an anatomical and functional neovagina to 11 patients efficiently, quickly and safely. Correct post-surgical dilation is still extremely important to keep the neovagina's size > 6 cm. RESULTS Histological and immunohistochemical analysis demonstrated the formation of a stratified squamous epithelium with strong marking for cytokeratins, FGF and EGFR, similar to healthy adult vaginal tissue. CONCLUSIONS Since NTFS is a low cost and easily accessible biomaterial, this technique proves to be an inexpensive therapeutic possibility for the health system with excellent advantages for patients.

Abstract
Injury from the severe burn is exacerbated by a persistent inflammatory response. This response is mediated by cytokines and chemokines, which are released from various immune cells, including mast cells. In this study, the ability of the acellular ovine small intestine submucosa (AOSIS) to load and release of Mineral Pitch (MP) was first investigated, and it was found that the preparation of the scaffold by a modified method enables it to load and release water-soluble drugs. Then, 32 male Wistar rats were divided into four groups, a third-degree burn was created, and except for the control group, the others were treated with: AOSIS, WJ-MSCs seeded AOSIS, or AOSIS loaded with WJ-MSCs and MP. Wound sampling on the 5th day after treatment showed that the number of intact and degranulated mast cells in the treatment groups was associated with a decrease compared to the control group. In the last group, this decrease was the largest (and statically significant (p < 0.05)). Also, by measuring the level of inflammatory factors in blood serum, it was found that in the treatment groups compared to the control group, IL-10 was associated with an increase, and TNF-α was associated with a decrease. The changes in inflammatory factors were more significant (p < 0.05) in the last group. So, our results indicate that AOSIS loaded with WJ-MSCs and MP could be used as an innovative tissue-engineered device to control inflammatory condition during burn wound healing.

Abstract
OBJECTIVE The harmful effects induced by ultraviolet exposition and the significant increment in skin cancer diagnosis confirm the necessity to develop effective and safe sunscreens. Limited efficacy and cutaneous adverse reactions of traditional formulations drove the incorporation of natural extracts into multifunctional sunscreens. Vaccinium myrtillus L. extract (VME), that contains anthocyanins and flavonoids, is a potential candidate for such systems. METHODS Considering that, we performed in vitro and in vivo tests to evaluate the sun protection factor (SPF), photostability and safety of sunscreen samples containing VME. RESULTS As main results, the SPF was reduced in both in vitro and in vivo evaluation in the presence of VME, nonetheless, the samples were photostable and safe. CONCLUSION Further investigation is required to better understand the unexpected effects of VME over photoprotection, decreasing the SPF value. As a conclusion, even with interesting findings, we highlight the importance of case-by-case investigations to develop multifunctional bioactive sunscreens.

Abstract
Nile tilapia (Oreochromis niloticus) skin is a well-known biomaterial used as an occlusive dressing for burn treatment. It is also an inexpensive and important source of collagen. This study aims to describe the ultrastructural aspects of Nile tilapia skin, assess its collagen amount and organization, and compare quantitative methods of histochemical and immunohistochemical analysis (in all sterilization steps for use in burn dressings). One sample (0.5 × 0.5 cm) of ten different fish skins was divided in four groups: in natura skin (IN), chemical sterilization (CH), additional irradiation (30 kGy) (IR), and skins used in burn treatment (BT) to compare histochemical and immunohistochemical findings of collagen amount and describe ultrastructural aspects through scanning electron microscopy. The amount of type I collagen decreased during sterilization and clinical use owing to gradual reduction of immunostaining (anti-collagen-I) and decreasing fiber thickness of the collagen, when compared to type III (Picrosirius-red-polarized light). The collagen fibers were rearranged at each sterilization step, with a low collagen percentage and large structural disorganization in BT. The amount of type-I collagen was further reduced after BT (p < 0.05). Both the methods did not exhibit a quantified value difference (p = 0.247), and a positive correlation (r = 0.927; 95 % CI = 0.720-0.983) was observed between them, with concordance for collagen quantification in similar samples, presenting a low systematic error rate (Dalberg coefficient: 6.70). A significant amount of type-I collagen is still observed despite sterilization, although clinical application further reduces type I collagen. Its quantification can be performed both by immunohistochemistry and/or Picrosirius Red reliably.

Abstract
BACKGROUND In a phase II study comparing Nile tilapia fish skin to silver sulfadiazine cream for outpatient management of superficial partial-thickness burns, the fish skin decreased reepithelialization time (average reduction, 1.43 days), dressing changes (average reduction, 3.72 dressings), and visual analogue scale pain scores. The present study aimed to further evaluate Nile tilapia fish skin efficacy for superficial partial-thickness burns. Unlike silver sulfadiazine cream, the fish skin has good adherence to the wound bed, which may prevent infections and decrease need for dressing changes. Thus, it could be a low-cost alternative to hasten healing and improve pain of burn patients. METHODS A phase III randomized controlled trial was conducted from April of 2017 to October of 2018 in Fortaleza, Brazil, and included 115 outpatients aged 18 to 70 years with superficial partial-thickness burns affecting 15 percent or less of body surface area and no previous treatment. Fifty-seven patients were treated with the glycerolized fish skin and 58 with silver sulfadiazine cream 1%. Primary outcomes were reepithelialization time, number of dressings, treatment-related costs, and pain intensity, assessed by means of visual analogue scale, Electronic von Frey, Burns Specific Pain Anxiety Scale, and analgesic use. Patients were evaluated every 48 hours. RESULTS Patients treated with fish skin required fewer days for reepithelialization (9.7 ± 0.6 days versus 10.2 ± 0.9 days; p = 0.001) and fewer dressings (1.6 ± 0.7 versus 4.9 ± 0.5; p < 0.001). They also had decreased analgesic needs and visual analogue scale, Burns Specific Pain Anxiety Scale, and Electronic von Frey measurements. Finally, fish skin use reduced the final average treatment-related cost per patient by 42.1 percent. CONCLUSION By hastening reepithelialization, improving burn-related pain, and decreasing treatment-related costs, Nile tilapia fish skin could benefit the resource-poor public health systems of developing countries.

Abstract
Glycerolized Nile tilapia skin (NTS) showed promising results when used for burn treatment in phases II and III randomized controlled trials. This pilot study aims to evaluate the effectiveness of lyophilized NTS (LNTS) as a temporary skin substitute for superficial partial-thickness burns by comparing it with silver-impregnated sodium carboxymethylcellulose dressing. This was a randomized, prospective, open-label, and controlled pilot study conducted in Fortaleza, Brazil, from April 2019 to December 2019. The 24 participants had ≥18 and ≤70 years of age and superficial partial-thickness burns affecting up to 10% of TBSA. Primary outcomes were the number of dressings performed and pain intensity, assessed via the Visual Analogue Scale and the Electronic von Frey. Secondary outcomes were the level of pain-related anxiety, assessed via the Burns Specific Pain Anxiety Scale, and analgesic consumption. In the test group, the number of dressings and the patient-reported pain after dressing-related procedures were lower. Analgesic intake, pain-related anxiety, and both patient-reported and objectively measured pain before dressing-related procedures were similar for the treatment groups. No adverse effects were detected. LNTS shares the same characteristics of an "'ideal'" wound dressing demonstrated by glycerolized NTS in previous studies. Also, it demonstrated noninferiority for burn management when compared with silver-impregnated sodium carboxymethylcellulose dressing. The safety and efficacy of LNTS demonstrated in this pilot study may allow the development of larger phases II and III RCTs in a near future.

Abstract
Tilapia fish skin has demonstrated promise as a stable and practical biological dressing to be used in wound and burn management. However, the appropriate sterilization technique of the Tilapia fish skin is crucial before its clinical application. The standard sterilization technique must eliminate harmful pathogens but maintain the structural and biochemical properties that could compromise the dressing function. This study investigated and compared the efficiency of three sterilizing agents; chlorhexidine gluconate 4% (CHG), povidone iodine 10% (PVP-I), and silver nanoparticles (25 μg/mL) (AgNPs), at three different times (5, 10, and 15 min) on Tilapia fish skin based on the microbial count, histological and collagen properties. Among the sterilization procedures, AgNPs showed rapid and complete antimicrobial activity, with a 100% reduction in microbial growth of the fish skin throughout the treated times. Furthermore, AgNPs did not impair the cellular structure or collagen fibers content of the fish skin. However, CHG and PVP-I caused alterations in the collagen content. This study demonstrated that the AgNPs treatment of Tilapia fish skin provided sterile skin while preserving the histological properties and structural integrity. These findings provide an efficient and quick sterilization method suitable for Tilapia fish skin that could be adopted as a biological dressing.

Abstract
Background The use of biological dressings has recently emerged in the management of burns and wounds. The aim of the present study was to evaluate the Nile tilapia skin as a biological dressing for full-thickness cutaneous metacarpal wounds in donkeys. The study was conducted on nine clinically healthy donkeys (n = 9). Here, fish skin dressings were obtained from fresh Nile tilapia (Oreochromis niloticus and sterilized by immersion in silver nanoparticles (AgNPs) solution for 5 min, with no change in collagen content. Bilateral, circular full-thickness excisional skin wounds (2 cm in diameter) were created on the dorsal aspect of the mid-metacarpals of each donkey. Wounds on the right metacarpals (treated wounds, n = 9) were dressed with sterile fish skins, while wounds on the left metacarpals (control wounds, n = 9) were dressed with sterile non-adherent dressing pads without any topical applications. Wound dressings were changed weekly. Wounds were evaluated microbiologically, grossly, and histologically on days 7, 14, and 21 post-wound inductions. Results Fish skin-dressed wounds showed a significant (P < 0.0001) reduction in microbial counts (Total viable bacterial count, Staphylococcal count, and Coliform count), a significant (P < 0.0001) decrease in the wound size, and a significant reduction (P < 0.0001) in the epithelial gap compared to the untreated wounds. No frequent dressing changes were needed. Conclusions Fish skin dressing accelerated the wound healing process and efficiently inhibited the local microbial activity and exuberant granulation tissue formation suggesting its reliable and promising application for metacarpal wounds of donkeys.

Abstract
Burns represent the fifth most common cause of nonfatal childhood injuries in the world. The Nile tilapia skin (Oreochromis niloticus) is widely available in Brazil and demonstrated, in previous studies, noninfectious microbiota, morphological structure similar to that of human skin, and good outcomes when used as a xenograft for treatment of experimental burns in rats. A 3-year-old boy was admitted to a burn treatment center in Fortaleza, Brazil, with scalds in the left side of the face, neck, anterior thorax, abdomen, and left arm. Involvement of 18% of total body surface area with superficial partial thickness burns was calculated. After local Institutional Review Board approval and written permission from the patient's legal caregiver were obtained, application of tilapia skin as an occlusive dressing was performed. Good adherence of tilapia skin to the wound bed was detected. The patient was discharged from the hospital with a total of 10 days required for the complete re-epithelialization of his superficial partial thickness burn. No adverse effects were noted. We believe that further studies conducted by our researchers will allow this innovative, low-cost, widely available and easy to apply biomaterial to firm itself as a relevant option in the therapeutic arsenal of pediatric burns, producing significant social and financial impact for the health system.

Abstract
Despite a considerable decrease in its incidence worldwide, burns remain the fourth most common type of trauma. The majority of burns are small, with 75% of injuries treated on an outpatient basis. Tilapia skin, as a biological material, has been suggested as an option for the management of burn wounds. After good results were obtained with the use of a glycerolised version of tilapia skin in burned children and adults, it was hypothesised that similar outcomes could be achieved with the use of a lyophilised version of tilapia skin. We report the case of a 33-year-old female patient with scalds to the upper abdomen, and both breasts, arms and forearms. Involvement of 10% of total body surface area with superficial partial thickness burns was calculated. The good adherence of tilapia skin to the wound bed, a 10-day period for complete re-epithelialisation of the wounds and the absence of side effects suggested that the lyophilised version of tilapia skin is effective for burn treatment. Compared with glycerolisation, lyophilisation is thought to permit extended storage of sterile tissue and decreased costs related to distribution and transport, but further studies are needed to confirm this.

Abstract
This study aims to evaluate the efficacy of Nile tilapia skin as a xenograft for the treatment of partial-thickness burn wounds in children. This is an open-label, monocentric, randomized phase II pilot study conducted in Fortaleza, Brazil. The study population consisted of 30 children between the ages of 2 and 12 years with superficial "partial-thickness" burns admitted less than 72 hours from the thermal injury. In the test group, the tilapia skin was applied. In the control group, a thin layer of silver sulfadiazine cream 1% was applied. Tilapia skin showed good adherence to the wound bed, reducing the number of dressing changes required, the amount of anesthetics used, and providing benefits for the patients and also for healthcare professionals, by reducing the overall work load. The number of days to complete burn wound healing, the total amount of analgesics required throughout the treatment, burn improvement on the day of dressing removal, and pain throughout the treatment were similar to the conventional treatment with silver sulfadiazine. Thus, tilapia skin can be considered an effective and low-cost extra resource in the therapeutic arsenal of pediatric superficial partial thickness burns.

Abstract
Abstract
Skin substitutes are considered a useful alternative for occlusive dressings in the treatment of superficial burns as they reduce the frequency of dressing replacement. This phase II randomized controlled trial aimed to evaluate the efficacy of Nile tilapia (Oreochromis niloticus) skin as an occlusive xenograft dressing for the treatment of burn wounds in humans. In order to assess the use of tilapia skin, the following variables were evaluated: number of days for wound healing, the number of times the occlusive dressing was changed, use of anesthetics or analgesics, pain assessment using the Visual Analogue Scale, and evaluation of burn improvement on the day of dressing removal. In total, 62 participants completed the study. It was found that in participants treated with tilapia skin, complete reepithelialization occurred in significantly fewer days; reported pain intensity was lower (study arms B and C), the amount of anesthetics/analgesics required was lower (study arms B and C), and the necessity of dressing changes was significantly reduced in comparison with volunteers treated with silver sulfadiazine. In our study, the tilapia skin xenograft showed good efficacy as an occlusive biological dressing for burn wound treatment in humans.

Abstract
Tilapia skin has non-infectious microbiota, high amounts of type I collagen, and similar morphological structure to human skin, so it has been suggested as a potential xenograft for the management of burn wounds. A 23-year-old male patient, with no comorbidities, arrived at our burn treatment center after a thermal injury caused by contact with flames from a gunpowder explosion. Superficial partial thickness burns were present in his right upper limb and deep partial thickness burns were present in his left upper limb. Tilapia skin was applied to the lesions, leading to complete reepithelialization within 12 and 17 days of treatment, respectively. No dressing changes were needed and no side effects were observed. Tilapia skin carries the promise of an innovative, easy-to-apply and highly available product that can become the first nationally studied animal skin registered by the National Sanitary Surveillance Agency for use in the treatment of burns.
