Abstract
Globally, high death rates and poor quality of life are caused mainly by inflammatory diseases. Corticosteroids, which may have systemic side effects and would enhance the risk of infection, are the common forms of therapy. The field of nanomedicine has created composite nanoparticles that carry a pharmacological carrier and target ligands for distribution to sites of inflammation with less systemic toxicity. However, their relatively large size often causes systemic clearance. An interesting approach is metal-based nanoparticles that naturally reduce inflammation. They are made not only to be small enough to pass through biological barriers but also to allow label-free monitoring of their interactions with cells. The following literature review discusses the mechanistic analysis of the anti-inflammatory properties of several metal-based nanoparticles, including gold, silver, titanium dioxide, selenium, and zinc oxide. Current research focuses on the mechanisms by which nanoparticles infiltrate cells and the anti-inflammatory techniques using herbal extracts-based nanoparticles. Additionally, it provides a brief overview of the literature on many environmentally friendly sources employed in nanoparticle production and the mechanisms of action of various nanoparticles.

Abstract
Functional foods, defined as whole foods that provide health benefits beyond their nutritional value, may provide multiple dermatologic benefits. Research studies have documented multiple benefits, including enhanced skin barrier function, improved wound healing, radiance, photoprotection, and hormonal regulation. Although the majority of research to date has involved small-scale human interventions or animal models, promising findings have been noted. A number of potential molecular mechanisms have been described, such as the ability of some foods to combat oxidative stress and thus reduce visible and histologic skin changes in response to UV radiation. Additional mechanisms have been described for wound healing, photo-carcinogenesis, and other outcomes. In this review, we discuss the potential dermatologic role of functional foods in order to advocate for larger-scale, evidence-based, human studies to expand this promising field.

Abstract
Traditional healers are often practiced in rural areas owing to cultural beliefs and are known to provide various forms of healthcare and home remedies. Patients in the Mediterranean region rely on traditional medicine to cure a variety of health concerns, like skin burns. This study was conducted to identify the various practices used by traditional healers for treating skin burns. The survey was conducted in 18 Arab countries, including Syria, Iraq, Jordan, Saudi Arabia, Egypt, United Arab Emirates, Algeria, Bahrain, Palestine, Kuwait, Oman, Qatar, Lebanon, Yemen, Tunisia, Oman, Morocco, and Sudan. Between September 2020 and July 2021, an online questionnaire was administered to 7530 participants from 12 Asian and 5 African countries. The survey was designed to gather information from common medicinal plant users and herbalists on their practices as specialists in using various herbal and medicinal plant products for diagnosis and treatment. Among the participants, 2260 had a scientific background in plant application, and the study included one phytotherapeutic professional. The crude-extraction technique was favored, by Arabic folk, for plant preparation over the maceration and decoction method. Olive oil was the most commonly used product among participants as an anti-inflammation and for scar reduction. Aloe vera, olive oil, sesame, Ceretonia siliqua, lavender, potato, cucumber, shea butter, and wheat flour are used as crude drugs to reduce pain because of their analgesic and cooling effects. The present study is the first database of medicinal plants with burn-healing properties conducted in Arab countries. These plants can be employed in the search for new bioactive substances through pharmacochemical investigations, as well as in the development of new formulations containing a combination of these plants.

Abstract
Olive oil has beneficial effects on skin wound healing due to its anti-inflammatory and antioxidant properties; however, the mechanism by which olive oil promotes wound healing is unclear. We evaluated the mechanisms involved in Nrf2 pathway activation by olive oil and its role in cell survival and migration in mouse dermal fibroblasts in a short-term exposition. Our data demonstrated that olive oil and oleic acid promoted reactive oxygen species (ROS) production, while olive oil and hydroxytyrosol stimulated nuclear factor erythroid 2-related factor 2 (Nrf2) activation. Olive oil-mediated ROS production increased nuclear factor kappa B p65 expression, while olive oil-stimulated reactive nitrogen species production augmented the levels of Nrf2. Olive oil augmented cell proliferation, cell migration, and AKT phosphorylation, but decreased apoptotic cell number and cleaved caspase-3 levels. The effect of olive oil on cell migration and protein levels of AKT, BCL-2, and Nrf2 were reversed by an Nrf2 inhibitor. In conclusion, the activation of the Nrf2 pathway by olive oil promotes the survival and migration of dermal fibroblasts that are essential for the resolution of skin wound healing.

Abstract
BACKGROUND AND AIM The study evaluated the impact of two types of high fat diet on the outcomes of acute pulmonary failure. METHODS A total of 93 Ventilated acute pulmonary failure patients with enteral feeding were assigned randomly to the control group with carbohydrate-based formula (protein: 20%, fat: 30%, carbohydrate: 50%) and two study groups with fat-based formula, including group A (protein: 20%, In equal proportions of olive and sunflower oil 45%, charbohydrate:35%) and group B (protein: 20%, sunflower oil:45%, charbohydrate:35%). The diets were prescribed for 14 days. RESULTS In each group, 16 patients completed the study. The PaCO2 decreased significantly in the study group A compared with the control group at weaning. The risk of separation from mechanical ventilation during study period was eight times higher in the study group A than the control group. On day 10 of intervention, serum hs-CRP decreased significantly in the control group and the study group A compared to the baseline. Serum concentration of total antioxidant capacity was increased significantly in the study group A on day 10 of the intervention, but in the other two groups it was reduced. Gastrointestinal complications, including diarrhea and high gastric residual volume, were not different between the groups. CONCLUSION With a fat-based diet high in olive oil, more patients were weaned during the study period. This diet reduced the PaCo2 at weaning, reduced the serum level of hs-CRP, and increased the serum level of total antioxidant capacity concentration. Fat-based diet high in sunflower oil did not have any beneficial effects on outcomes.

Abstract
Few studies have evaluated the effects of olive oil on normal tissues like skin and its components. Hence, we investigated whether olive oil could increase the production of ROS and oxidative damage in murine dermal fibroblast cultures in a short-term exposition. In addition, we evaluated the role of oleic acid and hydroxytyrosol, which are the two most important components of olive oil, in the associated mechanisms of action, and the metabolism of long-chain fatty acids from olive oil. To study this, neonatal murine dermal fibroblasts (NMDF) were incubated with olive oil, oleic acid, or hydroxytyrosol for 24 or 72 h. The NMDF incubated with olive oil or oleic acid showed an increase in the production of ROS after 24 h, lipid peroxidation, and protein carbonylation after 72 h, as well as increased expression of nuclear factor-kappa B (NF-κB) p65 and cyclooxygenase-2 (COX-2) after 72 h. However, NMDF treated with olive oil or hydroxytyrosol demonstrated an increase in the expression of nuclear factor-erythroid2-related factor 2 (NRF2) and heme oxygenase-1 (HO-1) after 72 h. In addition, NMDF treated with olive oil also showed an increase in the protein expression of diacylglycerol acyltransferase1 (DGAT1), which promotes triacylglycerol synthesis, and in the levels of triacylglycerols. The microscopic analysis showed Nile red-positive lipid droplets inside olive oil-treated NMDF after 72 h. Moreover, gas chromatography-mass spectrometry demonstrated high levels of oleic acid in the olive oil-treated NMDF after 72 h. In conclusion, oleic acid present in the olive oil promotes the production of ROS and oxidative damage in murine dermal fibroblasts, which leads to NF-κB p65 and COX-2 expression, while hydroxytyrosol promotes NRF2 and HO-1 expression. In addition, NMDF area capable of absorbing long-chain fatty acids derived from olive oil, which promotes the synthesis and the accumulation of triacylglycerols into cytoplasm of NMDF through DGAT1 activation.

Abstract
Wound healing is a complex process and some agents have been reported to accelerate it. The aim of this study was to evaluate the healing effect of Eucerin-based ointments of lemon, sesame and olive oils on infected full-thickness wounds in rats. Wounds were created on the dorsal surface of Male Albino Wistar rats (n = 12). Wounds were treated with an Eucerin-based ointment containing either of lemon, sesame or olive oils (33% w/w) twice a day for 14 days. Histopathology results showed that contraction of wounds treated with lemon and sesame oils was higher than in the olive oil and control groups on days 10 and 14. In the lemon- and sesame-oil treated groups, on day 14, 50% of rat lesions were completely healed. Total number of inflammatory cells in lemon oil treatment group was significantly smaller than that of others on day 14 (p < 0.001). Also, thickness of the epidermal layer and rejuvenation of the hair follicles and other skin appendages was normal in lemon and sesame oil treated groups. The lemon and sesame oil ointments accelerated the healing process of wounds in macroscopic, morphological and morphmetrical analyses. Therefore, lemon and sesame oil ointments could be considered as alternative dressings for infected full-thickness wounds because of improved wound healing characteristics.

Abstract
Wound healing is a physiological event that generates reconstitution and restoration of granulation tissue that ends with scar formation. As omega fatty acids are part of membrane phospholipids and participate in the inflammatory response, we investigated the effects of omega-3, omega-6, and omega-9 fatty acids in the form of oils on wound healing. Linseed (LO), evening primrose (EPO), and olive oils (OO) rich in omega-3, omega-6, and omega-9 fatty acids were formulated into emulsions and were topically applied on rats with excision wounds. All omega-3-, omega-6-, and omega-9-rich oil formulations were found to accelerate wound closure compared to untreated, with significant improvement (p < 0.05) being observed at day 14. EPO induced early deposition of collagen as evaluated by Masson trichrome staining that correlated well with the hydroxyproline content assay, with the highest level at days 3 and 7. Vascular endothelial growth factor (VEGF) showed greater amount of new microvasculature formed in the EPO-treated group, while moderate improvement occurs in the LO and OO groups. EPO increased both the expression of proinflammatory cytokines and growth factors in the early stage of healing and declined at the later stage of healing. LO modulates the proinflammatory cytokines and chemokine but did not affect the growth factors. In contrast, OO induced the expression of growth factors rather than proinflammatory cytokines. These data suggest that LO, EPO, and OO emulsions promote wound healing but they accomplish this by different mechanisms.

Abstract
INTRODUCTION Systematic reviews collate trial data to provide evidence to support clinical decision-making. For effective synthesis, there must be consistency in outcome reporting. There is no agreed set of outcomes for reporting the effect of burn care interventions. Issues with outcome reporting have been identified, although not systematically investigated. This study gathers empirical evidence on any variation in outcome reporting and assesses the need for a core outcome set for burn care research. METHODS Electronic searches of four search engines were undertaken from January 2012 to December 2016 for randomised controlled trials (RCTs), using medical subject headings and free text terms including 'burn', 'scald' 'thermal injury' and 'RCT'. Two authors independently screened papers, extracted outcomes verbatim and recorded the timing of outcome measurement. Duplicate outcomes (exact wording ± different spelling), similar outcomes (albumin in blood, serum albumin) and identical outcomes measured at different times were removed. Variation in outcome reporting was determined by assessing the number of unique outcomes reported across all included trials. Outcomes were classified into domains. Bias was reduced using five researchers and a patient working independently and together. RESULTS 147 trials were included, of which 127 (86.4%) were RCTs, 13 (8.8%) pilot studies and 7 (4.8%) RCT protocols. 1494 verbatim clinical outcomes were reported; 955 were unique. 76.8% of outcomes were measured within 6 months of injury. Commonly reported outcomes were defined differently. Numbers of unique outcomes per trial varied from one to 37 (median 9; IQR 5,13). No single outcome was reported across all studies demonstrating inconsistency of reporting. Outcomes were classified into 54 domains. Numbers of outcomes per domain ranged from 1 to 166 (median 11; IQR 3,24). CONCLUSIONS This review has demonstrated heterogeneity in outcome reporting in burn care research which will hinder amalgamation of study data. We recommend the development of a Core Outcome Set.

Abstract
Background and Aims: The aim of this study was to evaluate the preventive effects of high-fat enteral feeding on glycemic control and clinical outcomes in critically ill patients: a randomized clinical trial. Materials and Methods: This study was done on 42 normoglycemic patients admitted to Intensive Care Unit (ICU). Patients were randomly classified into three groups of 14 each. Control group (A) received carbohydrate-based diet (protein: 20%, fat: 30%, and carbohydrate: 50%), study groups received two types of high-fat diet; Group B (protein: 20%, fat: 45% including half of olive oil and half sunflower oil, and carbohydrate: 35%); and Group C (protein: 20%, fat: 45% including sunflower oil, and carbohydrate: 35%) in the first 48 h of admission. Results: Basal characteristics of participants were the same. After the feeding trial, there was no difference between the groups in mean plasma and capillary glucose levels and insulin requirements. Serum high density lipoprotein (HDL)-cholesterol level was increased significantly in Group B on day 10 compared to admission level (40.75 ± 5.58 vs. 43.56 ± 2.25, P = 0.05). We did not find any difference in organ failure involvement and mortality rate between groups. The number of ICU free days was significantly more in Group B compared to the control group (P = 0.04). Conclusion: High-fat diets have no preventive effect on stress hyperglycemia. High monounsaturated fat diet may increase serum HDL-cholesterol level and decrease the length of stay in ICU.

Abstract
Bigels are biphasic systems formed by water-based hydrogels and oil-based organogels, mainly studied, in the last few years, for pharmaceutical and cosmetic application focused on the controlled delivery of both lipophilic and hydrophilic active agents. The rheological properties of bigels depend on both the amount and the rheological characteristics of single structured phases. Moreover, it can be expected that, at large fractions of one of the starting gels, systems more complex than oil-in-water or water-in-oil can be obtained, yielding bicontinuous or matrix-in-matrix arrangement. Model bigels were investigated from a microstructural (i.e. microscopy and electrical conductivity tests) and rheological point of view. The hydrogel was prepared by using a low-methoxyl pectin whereas the organogel was prepared by using olive oil and, as gelator, a mixture of glyceryl stearate and policosanol. Model bigels were obtained by increasing the amount of organogel mixed with the hydrogel, and microstructural characterisation evidenced an organogel-in-hydrogel behaviour for all investigated samples, even though at the highest organogel content a more complex structure seems to arise. A semi-empirical model, based on theoretical equations developed for suspensions of elastic spheres in elastic media, was proposed to relate bigel rheological properties to single phase properties and fractions.

Abstract
Medicinal plants and their secondary metabolites are progressively used in the treatment of diseases as a complementary medicine. Inflammation is a pathologic condition that includes a wide range of diseases such as rheumatic and immune-mediated conditions, diabetes, cardiovascular accident, and etcetera. We introduce some herbs which their anti-inflammatory effects have been evaluated in clinical and experimental studies. Curcuma longa, Zingiber officinale, Rosmarinus officinalis, Borago officinalis, evening primrose, and Devil's claw are some of the introduced medicinal herbs in this review. Since the treatment of inflammation is not a one-dimensional remedy, this review tries to reach a multidimensional therapeutic approach to inflammation with the help of herbal medicine and modification in lifestyle.

Olive oil-induced reduction of oxidative damage and inflammation promotes wound healing of pressure ulcers in mice. J Dermatol Sci 2016; 83:60-9. [PMID: 27091748 DOI: 10.1016/j.jdermsci.2016.03.012] [Citation(s) in RCA: 56] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2016] [Revised: 03/18/2016] [Accepted: 03/30/2016] [Indexed: 02/02/2023]
Abstract
BACKGROUND The overproduction of reactive oxygen species (ROS) and exacerbated inflammatory response are the main events that impair healing of pressure ulcers. Therefore, olive oil may be a good alternative to improve the healing of these chronic lesions due to its anti-inflammatory and antioxidant properties. OBJECTIVE This study investigated the effect of olive oil administration on wound healing of pressure ulcers in mice. METHODS Male Swiss mice were daily treated with olive oil or water until euthanasia. One day after the beginning of treatment, two cycles of ischemia-reperfusion by external application of two magnetic plates were performed in skin to induced pressure ulcer formation. RESULTS The olive oil administration accelerated ROS and nitric oxide (NO) synthesis and reduced oxidative damage in proteins and lipids when compared to water group. The inflammatory cell infiltration, gene tumor necrosis factor-α (TNF-α) expression and protein neutrophil elastase expression were reduced by olive oil administration when compared to water group. The re-epithelialization and blood vessel number were higher in the olive oil group than in the water group. The olive oil administration accelerated protein expression of TNF-α, active transforming growth factor-β1 and vascular endothelial growth factor-A when compared to water group. The collagen deposition, myofibroblastic differentiation and wound contraction were accelerated by olive oil administration when compared to water group. CONCLUSION Olive oil administration improves cutaneous wound healing of pressure ulcers in mice through the acceleration of the ROS and NO synthesis, which reduces oxidative damage and inflammation and promotes dermal reconstruction and wound closure.

Abstract
Appropriate nutrition is an essential component of intensive care management of children with acute respiratory distress syndrome (ARDS) and is linked to patient outcomes. One out of every two children in the pediatric intensive care unit (PICU) will develop malnutrition or have worsening of baseline malnutrition and present with specific micronutrient deficiencies. Early and adequate enteral nutrition (EN) is associated with improved 60-day survival after pediatric critical illness, and, yet, despite early EN guidelines, critically ill children receive on average only 55% of goal calories by PICU day 10. Inadequate delivery of EN is due to perceived feeding intolerance, reluctance to enterally feed children with hemodynamic instability, and fluid restriction. Underlying each of these factors is large practice variation between providers and across institutions for initiation, advancement, and maintenance of EN. Strategies to improve early initiation and advancement and to maintain delivery of EN are needed to improve morbidity and mortality from pediatric ARDS. Both, over and underfeeding, prolong duration of mechanical ventilation in children and worsen other organ function such that precise calorie goals are needed. The gut is thought to act as a "motor" of organ dysfunction, and emerging data regarding the role of intestinal barrier functions and the intestinal microbiome on organ dysfunction and outcomes of critical illness present exciting opportunities to improve patient outcomes. Nutrition should be considered a primary rather than supportive therapy for pediatric ARDS. Precise nutritional therapies, which are titrated and targeted to preservation of intestinal barrier function, prevention of intestinal dysbiosis, preservation of lean body mass, and blunting of the systemic inflammatory response, offer great potential for improving outcomes of pediatric ARDS. In this review, we examine the current evidence regarding dose, route, and timing of nutrition, current recommendations for provision of nutrition to children with ARDS, and the current literature for immune-modulating diets for pediatric ARDS. We will examine emerging data regarding the role of the intestinal microbiome in modulating the response to critical illness.

Abstract
The potential of several drugs for full-thickness skin burns has been investigated, but the treatment of such burns remains a challenge in plastic surgery. The present study was designed to determine the effect of systemic and topical administration of piracetam and nimodipine on full-thickness skin burn wound healing. A total of 36 New Zealand male rabbits were divided into six groups. Full-thickness skin burns were produced in all the groups, except the control group. Piracetam was administered systemically (piracetam-IV) and topically (piracetam-C) for 14 days, and nimodipine was administered systemically (nimodipine-IV) and topically (nimodipine-C) over the burn wounds for 14 days. The sham group underwent burn injury but was not administered any drug. After 21 days, gross examination and histopathological analysis were performed and the results were compared statistically. Nimodipine-C and nimodipine-IV had no effect on burn wound healing. However, both piracetam-IV and piracetam-C significantly enhanced the healing of the full-thickness skin burn wounds, although the latter was more effective, useful and practical in burn wound healing. The histopathological features of the wounds in the piracetam-C group were closer to those of the control group than those of the other groups. Piracetam-C rather than piracetam-IV may promote full-thickness burn wound healing in rabbits.

Abstract
BACKGROUND With burn injuries involving a large total body surface area (TBSA), the body can enter a state of breakdown, resulting in a condition similar to that seen with severe lack of proper nutrition. In addition, destruction of the effective skin barrier leads to loss of normal body temperature regulation and increased risk of infection and fluid loss. Nutritional support is common in the management of severe burn injury, and the approach of altering immune system activity with specific nutrients is termed immunonutrition. Three potential targets have been identified for immunonutrition: mucosal barrier function, cellular defence and local or systemic inflammation. The nutrients most often used for immunonutrition are glutamine, arginine, branched-chain amino acids (BCAAs), omega-3 (n-3) fatty acids and nucleotides. OBJECTIVES To assess the effects of a diet with added immunonutrients (glutamine, arginine, BCAAs, n-3 fatty acids (fish oil), combined immunonutrients or precursors to known immunonutrients) versus an isonitrogenous diet (a diet wherein the overall protein content is held constant, but individual constituents may be changed) on clinical outcomes in patients with severe burn injury. SEARCH METHODS The search was run on 12 August 2012. We searched the Cochrane Injuries Group's Specialised Register, The Cochrane Library, MEDLINE (OvidSP), Embase (OvidSP), ISI WOS SCI-EXPANDED & CPCI-S and four other databases. We handsearched relevant journals and conference proceedings, screened reference lists and contacted pharmaceutical companies. We updated this search in October 2014, but the results of this updated search have not yet been incorporated. SELECTION CRITERIA Randomised controlled trials comparing the addition of immunonutrients to a standard nutritional regimen versus an isonitrogenated diet or another immunonutrient agent. DATA COLLECTION AND ANALYSIS Two review authors were responsible for handsearching, reviewing electronic search results and identifying potentially eligible studies. Three review authors retrieved and reviewed independently full reports of these studies for inclusion. They resolved differences by discussion. Two review authors independently extracted and entered data from the included studies. A third review author checked these data. Two review authors independently assessed the risk of bias of each included study and resolved disagreements through discussion or consultation with the third and fourth review authors. Outcome measures of interest were mortality, hospital length of stay, rate of burn wound infection and rate of non-wound infection (bacteraemia, pneumonia and urinary tract infection). MAIN RESULTS We identified 16 trials involving 678 people that met the inclusion criteria. A total of 16 trials contributed data to the analysis. Of note, most studies failed to report on randomisation methods and intention-to-treat principles; therefore study results should be interpreted with caution. Glutamine was the most common immunonutrient and was given in seven of the 16 included studies. Use of glutamine compared with an isonitrogenous control led to a reduction in length of hospital stay (mean stay -5.65 days, 95% confidence interval (CI) -8.09 to -3.22) and reduced mortality (pooled risk ratio (RR) 0.25, 95% CI 0.08 to 0.78). However, because of the small sample size, it is likely that these results reflect a false-positive effect. No study findings suggest that glutamine has an effect on burn wound infection or on non-wound infection. All other agents investigated showed no evidence of an effect on mortality, length of stay or burn wound infection or non-wound infection rates. AUTHORS' CONCLUSIONS Although we found evidence of an effect of glutamine on mortality reduction, this finding should be taken with care. The number of study participants analysed in this systematic review was not sufficient to permit conclusions that recommend or refute the use of glutamine. Glutamine may be effective in reducing mortality, but larger studies are needed to determine the overall effects of glutamine and other immunonutrition agents.
