Integrating human expertise & automated methods for a dynamic and multi-parametric evaluation of large language models' feasibility in clinical decision-making. Int J Med Inform 2024; 188:105501. [PMID: 38810498 DOI: 10.1016/j.ijmedinf.2024.105501] [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: 04/08/2024] [Revised: 05/09/2024] [Accepted: 05/22/2024] [Indexed: 05/31/2024]
Abstract
BACKGROUND Recent enhancements in Large Language Models (LLMs) such as ChatGPT have exponentially increased user adoption. These models are accessible on mobile devices and support multimodal interactions, including conversations, code generation, and patient image uploads, broadening their utility in providing healthcare professionals with real-time support for clinical decision-making. Nevertheless, many authors have highlighted serious risks that may arise from the adoption of LLMs, principally related to safety and alignment with ethical guidelines. OBJECTIVE To address these challenges, we introduce a novel methodological approach designed to assess the specific feasibility of adopting LLMs within a healthcare area, with a focus on clinical nursing, evaluating their performance and thereby directing their choice. Emphasizing LLMs' adherence to scientific advancements, this approach prioritizes safety and care personalization, according to the "Organization for Economic Co-operation and Development" frameworks for responsible AI. Moreover, its dynamic nature is designed to adapt to future evolutions of LLMs. METHOD Through integrating advanced multidisciplinary knowledge, including Nursing Informatics, and aided by a prospective literature review, seven key domains and specific evaluation items were identified as follows:A Peer Review by experts in Nursing and AI was performed, ensuring scientific rigor and breadth of insights for an essential, reproducible, and coherent methodological approach. By means of a 7-point Likert scale, thresholds are defined in order to classify LLMs as "unusable", "usable with high caution", and "recommended" categories. Nine state of the art LLMs were evaluated using this methodology in clinical oncology nursing decision-making, producing preliminary results. Gemini Advanced, Anthropic Claude 3 and ChatGPT 4 achieved the minimum score of the State of the Art Alignment & Safety domain for classification as "recommended", being also endorsed across all domains. LLAMA 3 70B and ChatGPT 3.5 were classified as "usable with high caution." Others were classified as unusable in this domain. CONCLUSION The identification of a recommended LLM for a specific healthcare area, combined with its critical, prudent, and integrative use, can support healthcare professionals in decision-making processes.

Abstract
Chronic non-healing wounds are a common consequence of skin ulceration in diabetic patients, with severe cases such as diabetic foot even leading to amputations. The interplay between pathological factors like hypoxia-ischemia, chronic inflammation, bacterial infection, impaired angiogenesis, and accumulation of advanced glycosylation end products (AGEs), resulting from the dysregulation of the immune microenvironment caused by hyperglycemia, establishes an unending cycle that hampers wound healing. However, there remains a dearth of sufficient and effective approaches to break this vicious cycle within the complex immune microenvironment. Consequently, numerous scholars have directed their research efforts towards addressing chronic diabetic wound repair. In recent years, gases including Oxygen (O2), Nitric oxide (NO), Hydrogen (H2), Hydrogen sulfide (H2S), Ozone (O3), Carbon monoxide (CO) and Nitrous oxide (N2O), along with gas-releasing materials associated with them have emerged as promising therapeutic solutions due to their ability to regulate angiogenesis, intracellular oxygenation levels, exhibit antibacterial and anti-inflammatory effects while effectively minimizing drug residue-induced damage and circumventing drug resistance issues. In this review, we discuss the latest advances in the mechanisms of action and treatment of these gases and related gas-releasing materials in diabetic wound repair. We hope that this review can provide different ideas for the future design and application of gas therapy for chronic diabetic wounds.

Abstract
Objective and Design The treatment of recurrent rosacea has always been a problem. Oral minocycline has been widely used in the treatment of rosacea. However, the efficacy and safety of ozonated hydrotherapy combined with LED yellow light irradiation and oral minocycline for mild to moderate papulopustular rosacea (PPR) has not been thoroughly studied. Methods Patients with rosacea who met the criteria and had complete clinical statistic admitted to our hospital from April 2021 to September 2022 were retrospectively collected and divided into combined therapy group and oral only group. The patients in the two groups were treated with minocycline for 8 weeks. In addition, the patients in combined therapy group were treated with ozone hydrotherapy once a week, followed by LED yellow light irradiation for a total of 4 weeks. The Investigator' s global assessment (IGA) score was used to assess the condition. The efficacy was evaluated using the patients' subjective symptom scores. Skin lesion images and adverse reactions were recorded. The recurrence rate was observed after 24 weeks of follow-up. Results A total of 39 patients included in the study. After 4 weeks of treatment, the effective rate was 90% in combined therapy group and 52.63% in oral only group (p<0.05). After 8 weeks of treatment, the total score of the patients' subjective symptom scores and the scores of itching and burning sensation in combined therapy group were lower than those in oral only group (p<0.05). After 24 weeks of follow-up, the recurrence rate of combined therapy group was 5%, and that of oral only group was 26.32%. The mild adverse reactions experienced by both groups disappeared during follow-up. Conclusion This combination therapy has a significant, rapid and safe therapeutic effect, especially in relieving itching and burning sensations, and may reduce the recurrence rate.

Abstract
Introduction Haemorrhoidal disease is one of the most common nowadays. It is often associated with a sedentary lifestyle. The leading cause of its development is also a functional disorder of the intestine and chronic constipation. To date, there is a steady growth rate of this disease, leading to its "rejuvenation". The current stage of development indicates the need for further improvement of surgical treatment and optimisation of patient management methods and the creation of uniform standards of care for this contingent of patients. Aim To evaluate the clinical effectiveness of the use of platelet-rich plasma therapy and the biologically active substance "ozoyl" in the treatment of haemorrhoidal disease. Material and methods The main group included 100 patients with chronic haemorrhoids who were operated on in the period from March 2021 to March 2022. For this group, autoplasma was used during surgery, and an ozoyl-based drug in the postoperative period. The remaining 100 participants of this study, assigned to the control group, underwent a conventional haemorrhoidectomy operation and standard patient management using a hydrophilic ointment based on chloramphenicol. Results After the conducted clinical studies, it was established that in the main group, the pain syndrome decreased by about 30%, considering the period from the first day of the postoperative period compared to the control group. The postoperative wound healed in the main group in the third week after the operation, unlike the control group, in which this event was noted in the fourth week. The patients did not complain during the examination 3 months later. Conclusions This study is of practical significance because haemorrhoidal disease today has a high prevalence, and an integrated approach is required for the treatment of such patients. Ozoyl is a powerful cell and tissue repairer.

Ozonated Sunflower Oil Embedded within Spray-Dried Chitosan Microspheres Cross-Linked with Azelaic Acid as a Multicomponent Solid Form for Broad-Spectrum and Long-Lasting Antimicrobial Activity. Pharmaceutics 2024; 16:502. [PMID: 38675163 PMCID: PMC11054446 DOI: 10.3390/pharmaceutics16040502] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 03/27/2024] [Accepted: 03/29/2024] [Indexed: 04/28/2024] Open
Abstract
Multicomponent solid forms for the combined delivery of antimicrobials can improve formulation performance, especially for poorly soluble drugs, by enabling the modified release of the active ingredients to better meet therapeutic needs. Chitosan microspheres incorporating ozonated sunflower oil were prepared by a spray-drying method and using azelaic acid as a biocompatible cross-linker to improve the long time frame. Two methods were used to incorporate ozonated oil into microspheres during the atomization process: one based on the use of a surfactant to emulsify the oil and another using mesoporous silica as an oil absorbent. The encapsulation efficiency of the ozonated oil was evaluated by measuring the peroxide value in the microspheres, which showed an efficiency of 75.5-82.1%. The morphological aspects; particle size distribution; zeta potential; swelling; degradation time; and thermal, crystallographic and spectroscopic properties of the microspheres were analyzed. Azelaic acid release and peroxide formation over time were followed in in vitro analyses, which showed that ozonated oil embedded within chitosan microspheres cross-linked with azelaic acid is a valid system to obtain a sustained release of antimicrobials. In vitro tests showed that the microspheres exhibit synergistic antimicrobial activity against P. aeruginosa, E. coli, S. aureus, C. albicans and A. brasiliensis. This makes them ideal for use in the development of biomedical devices that require broad-spectrum and prolonged antimicrobial activity.

Abstract
Besides being scarce, the drugs available for treating cutaneous leishmaniasis have many adverse effects. Ozone is an option to enhance the standard treatment due to the wound-healing activity reported in the literature. In this study, we evaluated the efficiency of ozonated sunflower oil as an adjuvant in treating cutaneous lesions caused by Leishmania amazonensis. BALB/c mice were infected with L. amazonensis, and after the lesions appeared, they were treated in four different schedules using the drug treatment with meglumine antimoniate (Glucantime®), with or without ozonated oil. After thirty days of treatment, the lesions' thickness and their parasitic burden, blood leukocytes, production of NO and cytokines from peritoneal macrophages and lymph node cells were analyzed. The group treated with ozonated oil plus meglumine antimoniate showed the best performance, improving the lesion significantly. The parasitic burden showed that ozonated oil enhanced the leishmanicidal activity of the treatment, eliminating the parasites in the lesion. Besides, a decrease in the TNF levels from peritoneal macrophages and blood leukocytes demonstrated an immunomodulatory action of ozone in the ozonated oil-treated animals compared to the untreated group. Thus, ozonated sunflower oil therapy has been shown as an adjuvant in treating Leishmania lesions since this treatment enhanced the leishmanicidal and wound healing effects of meglumine antimoniate.

Abstract
Support and management of second-intention wound healing involves frequent dressing changes having different properties. Dressings can range from simple ones, such as nonadherent dressings, to more complex options, such as foam, hydrocolloid, alginate or negative pressure dressings. Seven cats were enrolled in the study with a total of nine wounds of various sizes with different etiology sizes and localizations. Three methods of local ozone administration were used to cover more of the ozone properties in the treatment of wounds: bagging, perilesional subcutaneous infiltrations and lavages with ozonated saline. Evaluation of the healing process was performed by clinical observation and wound area measurements every seven days until the complete recovery of the patients. The results of this study should encourage clinicians to consider medical ozone as a new therapeutic approach with regenerative properties in the second-intention healing of cats presenting cutaneous wounds.

Abstract
Toxigenic fungi infect fruits and vegetables either during harvest or storage and create mycotoxins as secondary metabolites, which pose a serious threat to human and animal health throughout the food chain. Therefore, the objective of this study was to determine the inhibitory effect of OZO against the growth and spore germination of the Alternaria alternata fungal strain. Additionally, evaluation of the synthesis inhibition of Alternaria toxins (ATs), among which are alternariol (AOH), alternariol-9-methyl ether (AME), and tenuazonic acid (TeA) in the potato dextrose broth (PDB) medium and orange fruit after harvest. The results indicated that the inhibition zone was 29.0 ± 1.2 mm at 20 mg/L of OZO. The MIC and MFC values were recorded at 0.186 and 1.57 mg/mL, respectively. In this regard, OZO prevented conidia germination at 98.8% with the treatment of 5 mg/mL. OZO at 20 mg/mL was efficacious in producing a high loss in ATs production in the PDB medium, reaching 73.4, 76, and 67.1% for AOH, AME, and TeA, respectively. In addition, OZO prevents the biosynthesis of AOH and AME during the storage of orange fruits compared with the positive control sample. In contrast, 20 mg/mL reduced TeA accumulation and the appearance of Alternaria brown spot (ABS) in orange. To the best of our knowledge, this is the first report that studies OZO to control ATs in vitro in orange fruits.

Abstract
Wound infections with antibiotic-resistant bacteria, particularly the Gram-negative strains, pose a substantial health risk for patients with limited treatment options. Recently topical administration of gaseous ozone and its combination with antibiotics through portable systems has been demonstrated to be a promising approach to eradicate commonly found Gram-negative strains of bacteria in wound infections. However, despite the significant impact of ozone in treating the growing number of antibiotic-resistant infections, uncontrolled and high concentrations of ozone can cause damage to the surrounding tissue. Hence, before such treatments could advance into clinical usage, it is paramount to identify appropriate levels of topical ozone that are effective in treating bacterial infections and safe for use in topical administration. To address this concern, we have conducted a series of in vivo studies to evaluate the efficacy and safety of a portable and wearable adjunct ozone and antibiotic wound therapy system. The concurrent ozone and antibiotics are applied through a wound interfaced gas permeable dressing coated with water-soluble nanofibers containing vancomycin and linezolid (traditionally used to treat Gram-positive infections) and connected to a portable ozone delivery system. The bactericidal properties of the combination therapy were evaluated on an ex vivo wound model infected with Pseudomonas aeruginosa, a common Gram-negative strain of bacteria found in many skin infections with high resistance to a wide range of currently available antibiotics. The results indicated that the optimized combination delivery of ozone (4 mg h-1) and topical antibiotic (200 μg cm-2) provided complete bacteria eradication after 6 h of treatment while having minimum cytotoxicity to human fibroblast cells. Furthermore, in vivo local and systemic toxicity studies (e.g., skin monitoring, skin histopathology, and blood analysis) on pig models showed no signs of adverse effects of ozone and antibiotic combination therapy even after 5 days of continuous administration. The confirmed efficacy and biosafety profile of the adjunct ozone and antibiotic therapy places it as a strong candidate for treating wound infection with antimicrobial-resistant bacteria and further pursuing human clinical trials.

[PMID: 36789645 DOI: 10.1111/aji.13690] [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: 11/01/2022] [Revised: 12/27/2022] [Accepted: 01/28/2023] [Indexed: 02/16/2023] Open
Abstract
PROBLEM Endometriosis, a common and challenging condition, is a pelvic inflammatory condition that causes chronic pelvic pain (CPP) and infertility. Even though standard medical therapies and surgeries can help CPP, a large percentage of women remain symptomatic following the conventional treatments. Thus, there is a need to study new non-traditional therapeutic adjuncts in this patient population to improve their quality of life. One non-traditional therapeutic agent is Ozone Sauna Therapy (OST) which has been shown to have an anti-inflammatory action, but no studies have been performed to assess the efficacy of OST in women with endometriosis suffering with CPP. Another non-traditional therapeutic agent is Pulsed Electromagnetic Field Therapy (PEMF) where one small pilot study has shown that PEMF exposure to women with endometriosis and pelvic pain showed dramatic relief in symptoms. METHOD OF STUDY The HOCATT machine, by delivering a combination of both OST and PEMF in one machine, has been shown to improve fertility treatment outcome via in vitro fertilization (IVF) in older women by potentially improving oocyte quality. This study was conducted to assess the effect of the HOCATT machine use on the pain scale in patients struggling with CPP due to endometriosis. In the first study, eight women with endometriosis were administered transdermal and intravaginal OST + PEMF, twice a week for 3 weeks (total of 6 sessions). Once a week, the participants were asked to fill a pain scale. In the second study, 10 women were recruited in order to evaluate the changes in serum inflammatory markers following OST + PEMF exposure after 3-week period using the HOCATT machine twice a week (total of 6 sessions). RESULTS The participants had a mean age of 39.7 ± 1.1 years. The results showed a significant improvement in pain scale following the fourth session (p < .05) and a significant drop in serum levels of the inflammatory markers CRP (p = .0438) and IL-1β (p = .0031) and a significant increase in serum levels of IL-8 (p = .033). CONCLUSIONS This pilot study suggests that a combination of OST and PEMF using the HOCATT machine could potentially represent potential therapeutic adjuncts for women with inflammatory disorders such as endometriosis. There is a definite need for larger cohort studies and even randomized trials in order to better assess the efficacy of OST and PEMF in women with other inflammatory disorders.

Abstract
This study aimed to obtain and analyse Mentha piperita essential oil (MpEO) for the prospect of being used as an enhancement agent for the antimicrobial potential of ozone against gram-positive and gram-negative bacteria and fungi. The research was done for different exposure times, and it gained time-dose relationships and time-effect correlations. Mentha piperita (Mp) essential oil (MpEO) was obtained via hydrodistillation and further analysed by using GC-MS. The broth microdilution assay was used to determine the strain inhibition/strain mass growth by using spectrophotometric optical density reading (OD). The bacterial/mycelium growth rates (BGR/MGR) and the bacterial/mycelium inhibition rates (BIR/MIR) after ozone treatment in the presence and absence of MpEO on the ATTC strains were calculated; the minimum inhibition concentration (MIC) and statistical interpretations of the time-dose relationship and specific t-test correlations were determined. The effect of ozone on the following tested strains at maximum efficiency was observed after 55 s of single ozone exposure, in order of effect strength: S. aureus > P. aeruginosa > E. coli > C. albicans > S. mutans. For ozone with the addition of 2% MpEO (MIC), maximum efficacy was recorded at 5 s for these strains, in order of effect strength: C. albicans > E. coli > P. aeruginosa > S. aureus > S. mutans. The results suggest a new development and affinity regarding the cell membrane of the different microorganisms tested. In conclusion, the use of ozone, combined with MpEO, is sustained as an alternative therapy in plaque biofilm and suggested as helpful in controlling oral disease-causing microorganisms in medicine.

Abstract
This case report describes a new therapeutic approach for a domestic shorthaired female cat, who has an extensive posttraumatic wound in the right hind limb. After patient stabilization, general anesthesia was started and the wound was cleaned and debrided of devitalized tissues, followed by the application of ozone therapy and bandage. Eight sessions of ozone therapy were performed for 17 days until the application of the skin graft. Three more sessions of ozone therapy were performed every 3 days postoperatively. The bagging method and the perilesional infiltration method were used. The ozone therapy ensured an accelerated recovery of the patient without any complications. According to our knowledge, this is the first case report with the use of ozone therapy to support a free skin graft in a cat. The new therapeutic approach could be used to accelerate healing of the wounds with a significant lack of substance, by supporting pre- and post-operative skin grafts.

Abstract
Hydrogels, based on natural polymers, such as hyaluronic acid, are gaining an increasing popularity because of their biological activity. The antibacterial effect of ozone is widely known and used, but the instability the gas causes, severely limits its application. Ozone entrapment in olive oil by its reaction with an unsaturated bond, allows for the formation of stable, therapeutically active ozone derivatives. In this study, we obtained an innovative hydrogel, based on hyaluronic acid containing micro/nanocapsules of ozonated olive oil. By combination of the biocompatible polymer with a high regenerative capacity and biologically active ingredients, we obtained a hydrogel with regenerative properties and a very weak inhibitory effect against both bacterial commensal skin microbiota and pathogenic Candida-like yeasts. We assessed the stability and rheological properties of the gel, determined the morphology of the composite, using scanning electron microscopy (SEM) and particle size by the dynamic light scattering (DLS) method. We also performed Attenuated total reflectance Fourier transform infrared (FTIR-ATR) spectroscopy. The functional properties, including the antimicrobial potential were assessed by the microbiological analysis and in vitro testing on the HaCat human keratinocyte cell line. The studies proved that the obtained emulsions were rheologically stable, exhibited an antimicrobial effect and did not show cytotoxicity in the HaCat keratinocyte model.

Abstract
This critical review describes the squalene-ozone (SqOz) reaction, or squalene ozonolysis. Ambient ozone penetrates indoors and drives indoor air chemistry. Squalene, a component of human skin oil, contains six carbon-carbon double bonds and is very reactive with ozone. Bioeffluents from people contribute to indoor air chemistry and affect the indoor air quality, resulting in exposures because people spend the majority of their time indoors. The SqOz reaction proceeds through various formation pathways and produces compounds that include aldehydes, ketones, carboxylic acids, and dicarbonyl species, which have a range of volatilities. In this critical review of SqOz chemistry, information on the mechanism of reaction, reaction probability, rate constants, and reaction kinetics are compiled. Characterizations of SqOz reaction products have been done in laboratory experiments and real-world settings. The effect of multiple environmental parameters (ozone concentration, air exchange rate (AER), temperature, and relative humidity (RH)) in indoor settings are summarized. This critical review concludes by identifying the paucity of available exposure, health, and toxicological data for known reaction products. Key knowledge gaps about SqOz reactions leading to indoor exposures and adverse health outcomes are provided as well as an outlook on where the field is headed.

Abstract
Commonly found in atmospheric aerosols, cooking oils, and human sebum, unsaturated lipids rapidly decay upon exposure to ozone, following the Criegee mechanism. Here, the gas-surface ozonolysis of three oleic acid-based compounds was studied in a reactor and indoors. Under dry conditions, quantitative product analyses by 1H NMR indicate up to 79% molar yield of stable secondary ozonides (SOZs) in oxidized triolein and methyl oleate coatings. Elevated relative humidity (RH) significantly suppresses the SOZ yields, enhancing the formation of condensed-phase aldehydes and volatile C9 products. Along with kinetic parameters informed by molecular dynamics simulations, these results were used as constraints in a kinetic multilayer model (KM-GAP) simulating triolein ozonolysis. Covering a wide range of coating thicknesses and ozone levels, the model predicts a much faster decay near the gas-lipid interface compared to the bulk. Although the dependence of RH on SOZ yields is well predicted, the model overestimates the production of H2O2 and aldehydes. With negligible dependence on RH, the product composition for oxidized oleic acid is substantially affected by a competitive reaction between Criegee intermediates (CIs) and carboxylic acids. The resulting α-acyloxyalkyl hydroperoxides (α-AAHPs) have much higher molar yields (29-38%) than SOZs (12-16%). Overall, the ozone-lipid chemistry could affect the indoor environment through "crust" accumulation on surfaces and volatile organic compound (VOC) emission. In the atmosphere, the peroxide formation and changes in particle hygroscopicity may have effects on climate. The related health impacts are also discussed.

Abstract
BACKGROUND: The effect of ozonated Aloe vera in the treatment of radiation dermatitis has not been studied, while long-term use of topical steroids can cause some side effects.
AIM: The aim of the study was to analyze the effect of topical administration of ozonated Aloe vera oil on the expression of TGF-β and collagen density in the treatment of radiation dermatitis.
METHODS: 36 Sprague Dawley rats were randomized into six groups, namely, K1 (negative control-without therapy), K2 (positive control-hydrocortisone cream 2.5%), P1 (Aloe vera oil), P2, P3, and P4 (ozonized Aloe vera oil 300/600/1200 mg/ml). Termination and immunohistopathological analysis of TGF-β expression and collagen density were performed after 7 days of treatment.
RESULTS: Measurement of TGF-β expression by ANNOVA test showed a significant difference between groups p = 0.001. The Post Hoc LSD test showed significant differences between groups K1 and P1, P2, P3, and P4 also between groups K2 and P2, P3, and P4. Measurement of collagen density by Kruskal–Wallis test showed a significant difference between the treatment groups p < 0.001. Post hoc Mann–Whitney test of collagen density found a significant difference between groups K1 and P1, P2, P3, and P4 also between groups K2 and P2, P3, and P4. Spearman’s rho correlation test showed a strong and unidirectional relationship between TGF-β and collagen (p < 0.001 and r = 0.722).
CONCLUSION: Topical ozonated Aloe vera oil increased TGF-β expression and collagen density in radiation dermatitis.

Abstract
Objective To examine the bactericidal effects of three different states of medical ozone (liquid, gas, and oil) against drug-resistant strains of common bacteria on burn wounds, which could as a clinical reference. Methods Three multidrug-resistant strains of methicillin-resistant Staphylococcus aureus, pan-resistant Pseudomonas aeruginosa, and ESBLs Klebsiella pneumoniae were identified from burn wounds. The colonies of the three varieties of bacteria were each carried out using the pour plate method prior to the start of the experiment. Then, depending on the state of ozone, different treatment procedures are applied. Group of ozone gas: in a closed glass jar, the bacterial liquid was injected into a single layer of sterile gauze, and the ozone gas concentration was held at 50 g/mL. The bacterial liquid was diluted and combined directly with ozone water in the ozone water group. Ozone is a type of oil: after the emulsifier was added to the oil group. The gas, water, and oil groups were rapidly neutralized and counted again after 5, 10, and 30 minutes. Results Ozone gas and oil groups totally eliminated multidrug resistant bacteria in the above study within 30 minutes. (2) At 5 and 10 minutes, the difference in bactericidal effect between ozone gas group and ozone water and oil group was statistically significant (P<0.05), and there was no significant difference between ozone water and oil groups (P>0.05); at the time of 30 minutes, the effects of bactericidal effect between ozone water group and ozone gas and oil had no significance (P> 0.05). Conclusion Ozone has the ability to kill bacteria, depending on the treatment time, different ozone types should be chosen for sterilization and disinfection in clinical application.

Abstract
BACKGROUND Pediculosis is an infestation of lice affecting mostly children and spreads by direct contact with the hair of someone infected. Although topical application of a pediculicide such as permethrin shampoo is the most common cure for head lice, the addition of alternative treatments is necessary due to permethrin resistance and some safety concerns, including irritation, burning sensation, tingling, and breathing problems. Recent studies have indicated that ozone, which is an allotropic form of oxygen, may have anti-pediculosis effects. OBJECTIVE This study focused on the evaluation of an ozonated olive oil topical lotion for the treatment of pediculosis and the comparison of its effects with permethrin shampoo. METHODS 121 patients with proven head pediculosis were divided into two groups. They were treated with either topical ozonated olive oil lotion or permethrin shampoo for one week. RESULTS It was shown that the ozonation process enormously improved the physico-chemical properties of olive oil. Specifically, acid and peroxide values increased 60 fold and 200 fold, respectively, while there was a sharp decline for the iodine index (81.8±1.28 to 0 g iodine per 100 g). Additionally, all patients who received the ozonated olive oil lotion were entirely cured after one week of treatment, while those who were treated with permethrin, required to receive more. Statistical analysis of the data also proved this claim. CONCLUSION The prepared lotion has shown significant effects in controlling head lice. Thus, it can be prescribed as an effective anti-pediculosis medicine which is biocompatible and has high potential.

Abstract
Ozone is an allotropic form of oxygen, so in the medical field ozone therapy has special effects. Starting from the premise that bio-oxidative ozone therapy reduces the number of bacteria, in the present study two approaches were proposed: to evaluate the biological effects of ozone gas on the tooth enamel remineralization process and to demonstrate its impact on the morphology and confluence of human primary gingival cells, namely keratinocytes (PGK) and fibroblasts (HGF). The ozone produced by HealOzone was applied in vivo to 68 M1s (first permanent molars), both maxillary and mandibular, on the occlusal surfaces at pit and fissure. The molars included in the study recorded values between 13 and 24 according to the DIAGNOdent Pen 2190 scale, this being the main inclusion/exclusion criterion for the investigated molars. Because the gas can make contact with primary gingival cells during the ozonation process, both human gingival fibroblasts and keratinocytes were exposed to different doses of ozone (20 s, 40 s, 60 s), and its effects were observed with the Olympus IX73 inverted microscope. The contact of ozone with the human primary gingival cells demonstrates cell sensitivity to the action of ozone, this being higher in fibroblasts compared to keratinocytes, but it is not considered toxic because all the changes are reversible at 48 h after exposure.

Abstract
BACKGROUND Breast augmentation-mastopexy can yield an aesthetically attractive breast, but the 1-stage procedure is prone to unsatisfactory outcomes, including poor wound healing. OBJECTIVES The authors evaluated whether postsurgical application of a polyurethane bra cup coated with oxygen-enriched olive oil (NovoX Cup; Moss SpA, Lesa, Novara, Italy) would decrease pain associated with augmentation-mastopexy and improve the quality of the surgical scar. METHODS This retrospective study was conducted at a single center from January 2016 to June 2019. All patients underwent 1-stage augmentation-mastopexy with the inverted T incision. For 2 weeks postsurgically, wounds were dressed either with the oxygen-enriched olive oil bra or with Fitostimoline (Farmaceutici Damor SpA, Naples, Italy). Patients indicated their pain intensity on postoperative days 2, 3, and 10, and patients and independent observers scored scar quality on the Patient and Observer Scar Assessment Scale (POSAS) 6 and 12 months after the procedure. RESULTS A total of 240 women (120 per study arm) completed the study. All the patients had satisfactory aesthetic results, and there were no tolerability concerns with either postoperative dressing. Compared with patients in the Fitostimoline group, patients who received the oxygen-enriched olive oil bra cup had significantly lower pain levels, and their surgical scars were given better scores on the POSAS. CONCLUSIONS The results suggest that maintenance of the surgical wound in a film of oxygen-enriched olive oil for 2 weeks is a safe, effective modality for suppressing pain and promoting healing following augmentation-mastopexy.

[PMID: 33774942 PMCID: PMC8007438 DOI: 10.4142/jvs.2021.22.e27] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 01/19/2021] [Accepted: 02/04/2021] [Indexed: 12/12/2022] Open
Abstract
Background Ozone is an antimicrobial agent that in experimental and case-control studies has been found to exert a positive effect on wound healing. Wild and pet chelonians frequently present insidious wounds exhibiting secondary infections and/or delayed healing. Objectives Evaluate the effects of topical ozonated sunflower oil on second-intention healing of acute experimental skin wounds in red-eared sliders (Trachemys scripta elegans). Methods Randomised within-subject controlled study; Group 1 (n = 24) was used to assess clinical healing features; Group 2 (n = 12) was used for histological evaluation in which two sets of wounds were biopsied at 2, 7, 14, 21, 28 and 42 days over the course of the cicatrisation process. A single 6 mm diameter wound was made on each rear limb and topical ozonated (950 peroxide value) and non-ozonated sunflower oil were applied daily for one week on treated and contralateral control wounds, respectively. Results Mean wound size was significantly lower in the ozone-treated group at day 28 (p < 0.0001) with differences of clinical relevance (74.04% vs. 93.05% reduction of initial wound size). Histologically, the acute inflammatory reaction was enhanced in treated wounds, with significantly higher numbers of heterophils (p = 0.0016), lymphocytes (p < 0.001) and fibroblasts (p < 0.001). Conclusions Daily topical application of ozonated sunflower oil over the course of one week improved the healing of acute, full-thickness skin wounds in chelonians. This clinical outcome was histologically correlated with an enhanced acute inflammatory reaction, as well as the production and remodelling of collagen fibres.

Abstract
In the Vet field, there are lot of scientific publications with missing or incomplete data, poor case reports and papers without a control group or unrepresentative sample. Differences between animal and human blood composition, anatomy and physiology must be taken into consideration, especially in therapies not yet fully approved. Some practitioners produce their own ozonated solution or autohemotherapy, in the absence of information regarding the compatibility of the material used. Other than the properties of the commercial preparations, the standardization of both treatment methods and times influence the results obtained with ozone therapy.
The therapeutic use of ozone and its derivatives in the veterinary medicine it is still in an emergent stage. Gaseous ozone chemical instability makes necessary its extemporaneous preparation and the accordance about ozone treatments with the highest quality standards in publications is of paramount importance. Moreover, the numerous method of administration in different animal species, the prevalence of case reports, the deficiency of consistent evaluation of the outcomes, as well as the lack of standardization of the treatment operating procedures represents an open question for its spreading and official approval. The keywords “ozone”, “ozonated”, “ozonation” “ozonized”, “ozonization”, “oxygen-ozone therapy”, “veterinary”, “pets”, “animal” were used to perform a literature review using PubMed, Cochrane, Google Scholar, Zotero databases with the temporal restriction for published manuscripts starting from 2010. All the researches were critically evaluated, regardless of the impact factor, if any, of the journals in which they were presented. The deepening of the mechanisms of action of this bio-oxidative therapy can open new horizons on its use. The distinctive condition to achieve such a scenario is an improved knowledge of the qualitative/quantitative characteristics of ozone and its derivatives. All with the aim of taking nothing away to the cited original research papers, but of improving the promising therapeutic implications of ozone therapy in veterinary medicine as a standardization stimulus about this therapeutic resource with multiple application specificities.

Abstract
Oxygen is considered a key element in the complex tissue repair process. O3-Oil antiseptics are obtained from the chemical reaction between ozone and unsaturated fatty acids of vegetable oils. The purpose of this study was to assess the effectiveness of a commercially available O3-Oil in the management of recalcitrant burn wounds. This study involved 20 patients with mid-deep and deep burn wounds (average TBSA approximately 23%, range 7-35%). Patient average age was 47 years (range 26-74 years), 8 were male. The presence of exudate, pain and delayed re-epithelialization, absence of tissue necrosis and/or sepsis were the inclusion criteria for the topical use of O3-Oil. In each patient two clinically similar areas were identified and treated every 48 hours with O3-Oil (Group 1) and conventional medication (Group 2). All the patients had positive bacterial culture results before treatment. A quicker reduction of exudates and pain and a progressive and faster bacterial load reduction was observed in Group 1. Negative cultures were obtained after 4 days on average in Group 1 (range 1-7 days) and 8 days in Group 2 (range 5-11 days). The present study demonstrated that Novox® provides a significant antibacterial effect, while stimulating reparative processes. According to our experience, the use of gel or pad is useful for re-epithelializing lesions, while the impregnated gauzes, which tend to adhere to the wound, are better used on lesions with granulation tissue.

Abstract
Olive oil application in the cosmetic industry may be extended by its ozonation, bringing about new oil properties and increased stability. Olive oil treated with 0.04 mole O3 or 0.10 mole O3 per 100 g oil was subjected to chemical parameters evaluation and composition scrutinizing by gas chromatography–mass spectrometry (GC-MS) and headspace solid-phase microextraction (HS-SPME) GC-MS analysis. The biological activity of refined and ozonated oil included their antimicrobial properties by the agar diffusion method and cytotoxicity by the MTT assay towards two normal (LLC-PK1, HaCaT) and two cancerous (Caco-2, HeLa) cell lines. The oils served as the basis in cosmetic emulsions. The chosen organoleptic features, preservative efficacy in a challenge test, and persistency during six months of these formulations were assessed. However, the ozonation of the olive oil resulted in a decrease in unsaturated acids; several additional compounds were detected in the ozonated oil, which positively affect the physicochemical, sensory, and functional properties of cosmetic emulsions. Emulsions based on the ozonated olive oil retain their properties longer compared to emulsions based on the refined olive oil. Ozonated oil treated with 0.10 mole O3/100 g oil allowed increasing the shelf life of the non-preserved formulation up to six months. A weak inhibitory effect against Candida albicans and Aspergillus brasiliensis was also demonstrated for this emulsion in the challenge test. Moreover, an interesting aroma, slightly enhanced antimicrobial activity against Escherichia coli, Staphylococcus aureus, C. albicans, A. brasiliensis, and a lack of cytotoxicity at concentrations 625 µg mL−1 make the ozonated olive oil a promising raw material for the cosmetics and pharmaceutical industries.

Topical Application of Ozonated Oils for the Treatment of MRSA Skin Infection in an Animal Model of Infected Ulcer. BIOLOGY 2021; 10:biology10050372. [PMID: 33926041 PMCID: PMC8146315 DOI: 10.3390/biology10050372] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 04/17/2021] [Accepted: 04/22/2021] [Indexed: 01/01/2023]
Abstract
Simple Summary Methicillin-resistant Staphylococcus aureus is often found in skin lesions infected in particular in diabetic foot ulcers, in which the prevalence can reach 40%. Clinical methicillin-resistant Staphylococcus aureus is generally resistant to most classes of antibiotics and therefore it is necessary to develop new antimicrobial agents. Ozone has a recognized bactericidal activity and has been widely used as a clinical therapeutic agent for chronic wounds, such as ulcers and other injuries, due to its ability to heal wounds. This is a preliminary study that reports the effectiveness of ozonated oils on the eradication of skin infection in vivo. The study provides further insights into the antibacterial effect of ozone in infected skin ulcers in diabetic rats and also, the potential wound healing effect of ozonated oils. Furthermore, this is the first study investigating the efficacy of ozone in the eradication of diabetic foot ulcers infected by methicillin-resistant Staphylococcus aureus. Our results indicate that topical application of ozonated oils infected skin in rats have significant antimicrobial activity as well as wound healing capacity. Achieving the healing of infected diabetic foot wounds has become a challenge and ozonated oils may be used to treat these infections. Abstract Diabetic foot ulcers are a common cause of morbidity in diabetic patients. One of the main pathogens found in these ulcers is methicillin-resistant Staphylococcus aureus (MRSA). MRSA often carries resistance to several classes of antibiotics and their infections are becoming harder to treat. Therefore, new alternatives are urgently needed. Thus, this study aimed to investigate the capacity of topical ozonated oil application on the treatment of early-stage skin infected with MRSA in an animal model. Ozonated oil was prepared from a mixture of oils subjected to a gas stream of O2/O3 mixture. Sixteen Wistar rats were inoculated by an intradermic injection of MRSA suspension, producing an abscess lesion. After 3 days, the skin epidermis was removed to open the wound. Group 1 received an application of oil mixture without ozone treatment and Group 2 received an application of ozonated oil. After the treatment period, skin was collected, colony-forming units (CFU) of bacteria were quantified and the histological analysis of the skin was carried out. Skin samples from the control 1 and 2 had a bacterial load was of 1.1 × 105 and 5.7 × 103 CFU/mL, respectively. Group 2 showed better wound healing from mild to moderate epidermal regeneration. Topical application of ozonated vegetable oil in MRSA-infected skin in rats showed a small reduction of the bacterial load and better wound healing.

Ozonated oil effect for prevention of medication-related osteonecrosis of the jaw (MRONJ) in rats undergoing zoledronic acid therapy. Clin Oral Investig 2021; 25:6653-6659. [PMID: 33895916 DOI: 10.1007/s00784-021-03951-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 04/16/2021] [Indexed: 02/07/2023]
Abstract
OBJECTIVES The aim of this study was to evaluate the preventive effect of ozonated oil on the development of MRONJ-like lesions at tooth extraction sites in rats submitted to zoledronic acid treatment. MATERIALS AND METHODS Twelve rats were divided into two groups. Each rat received an injection of zoledronic acid solution once a week for 5 weeks before having its upper first molar extracted. In group 1, the clotted socket was maintained, while in the group 2, the socket was treated with ozonated oil for 10 min/day during 3 days. After euthanasia, block resection was performed for histological analysis. Necrotic bone was defined as the area of the bone with empty osteocyte lacunae and vital bone as the area with osteocyte-occupied lacunae. RESULTS There was no statistically significant difference between the groups in the average area of vital bone (p = 0.2248) and the average area of necrotic bone (p = 0.1208). However, the average area of vital bone in group 1 was smaller (24.1 ± 2.9 cells/cm2) than in group 2 (26.8 ± 4.2 cells/cm2), and the average area of necrotic bone in group 1 was higher (7.0 ± 2.5 cells/cm2) than in group 2 (4.0 ± 1.1 cells/cm2), indicating that ozonated oil may reduce the development of osteonecrosis. CONCLUSIONS Our findings suggest that ozonated oil might prevent MRONJ-like lesions at tooth extraction sites in rats submitted to a disease induction protocol. Further research should be conducted to confirm this hypothesis. CLINICAL RELEVANCE MRONJ has been reported as a complication of surgical dental procedures, and there are currently no predictable preventive therapies.

Abstract
BACKGROUND The search for ever more lasting and safe aesthetic modalities is a constant. For this reason, biostimulation is finding more and more space in clinics; relatively simple, effective, and safe procedures, a procedure that delivers what it promises. Biostimulation is nothing more than an increase in collagen production, primarily type I, with the aim of facial or body rejuvenation. AIMS Evaluated some years ago as remarkable antimicrobial therapy, today it gains notoriety for its versatility in other areas, one of which is biostimulation, which has been growing. This paper aims to report a case of biostimulation through ozone therapy, as well as the protocol used, its indications, and contraindications. PATIENTS/METHODS A case report of rejuvenation with ozone therapy and a literature review. RESULTS Among biostimulatory treatments available, one has been gaining space among professionals and scientific recognition, ozone therapy. CONCLUSION It is a promising aesthetic therapeutic modality with efficient and safe results and high patient compliance and satisfaction.

Abstract
Objective This study aimed to examine the effectiveness of ozonated Aloe vera oil on the wound healing response of full-thickness defect tissue in Sprague-Dawley rats, assessed by collagen thickness and the number of fibroblasts. Methods This was an experimental research method using control groups and treatment groups with a posttest only control group design. The results showed that collagen thickness in wounds tended to increase, assessed on day 3 and day 7 using Masson's trichrome staining and microscopic evaluation. Results There was a significant difference in the number of fibroblasts between the two control and treatment groups on days 3 and 7 tested using one-way Kruskal–Wallis test, with a value of p=0.001(p < 0.05), resulting in a significant difference in wound size reduction between the groups. Further post hoc analysis using the Mann–Whitney test indicated a significant difference between the control groups and the treatment groups (P0, P1 versus P3, P4, P5, P8, P9, and P10) with a value of p=0.009(p < 0.05). Conclusions Ozonated Aloe vera oil is effective in increasing the healing response of full-thickness defects, leading to the increase in the number of fibroblasts and collagen thickening that in turn accelerates wound healing in Sprague-Dawley rats.

Abstract
This study investigated the mechanism and efficacy of topical acidified aliphatic ester for treatment of axillary osmidrosis (AO). A total of 32 AO patients were enrolled in this study. In the initial pilot study, 20 patients were double-blindly, randomly divided into acidified aliphatic ester or aliphatic ester treatment groups, followed by efficacy evaluation after 4 weeks. Then, all patients (n = 32) were treated with topical acidified aliphatic ester for 16 weeks. Efficacy was evaluated at every 4 weeks, and at 3- and 6-month follow-ups. Changes of pH values and microecology at targeting sites were analyzed. In the first cohort (n = 20) of pilot study, acidified aliphatic ester showed significantly higher curative rate (60% vs 10%, P < .05) and effective rate (90% vs 30%; P < .05) than aliphatic ester. For the next 16 weeks, 25 of 32 cases completed treatment. Curative rate showed gradual and significant increases from 64% to 96% during the treatment courses (P = .001); it slightly but insignificantly decreased at 3- and 6- month follow-ups. Abundance of Corynebacterium and Anaerobic bacteria decreased while Staphylococcus increased after treatments. Axillary pH values negatively correlated with Staphylococcus abundance (r = -.40, P = .01) and positively with Corynebacterium abundance (r = .64, P = .01). We concluded that topical acidified aliphatic ester could effectively alleviate conditions of AO patients by reducing value of axillary pH and rebalancing axillary microecology.

Abstract
The aim of this study was to evaluate 3 different irrigation protocols using ozone on monoculture biofilm of Enterococcus faecalis. Fifty disto-buccal roots of maxillary first molars were instrumented up to the size 25.08, sterilized and then incubated with Enterococcus faecalis for 21 days for biofilm maturation in the root canal walls. After contamination, the initial collection (S1) was performed and the 50 samples were divided in 3 experimental groups (n = 15) and 1 positive control group (n = 5) as follows: Group1: Ozonated water (40 µg/ml); Group2: gaseous ozone (40 µg/ml); Group3: Ozonated water (40 µg/ml) under continuous ultrasonic irrigation (CUI) and, Group 4: 2.5% sodium hypochlorite (positive control). The final collection (S2) was performed using hedstroem files # 25 by scraping the root canal wall and absorbed paper cone. The collected samples were analyzed by CFU/ml count and qPCR. To compare the effect of irrigation methods and to investigate E. faecalis count data, Kruskal-Wallis and Wilcoxon nonparametric tests were used at p < 05. The values of the differences between the S1 values and the S2 values revealed that the groups did not differ significantly for either E. faecalis CFU count data (p = 0.713) or q-PCR (p = 0.185), however, it is observed that for all groups, the CFU count of E. faecalis decreased over 99%. For the q-PCR assay, the reduction was on the order of 74-95%. Only the NaOCl positive control group presented total elimination of CFU/mL bacterial counting. The ozone protocols assessed were similar in regard to Enterococcus faecalis reduction.

Aqueous ozone therapy improves the standard treatment of leishmaniasis lesions in animals leading to local and systemic alterations. Parasitol Res 2020; 119:4243-4253. [PMID: 33048207 DOI: 10.1007/s00436-020-06925-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Accepted: 10/07/2020] [Indexed: 12/16/2022]
Abstract
The current treatment of leishmaniasis presents some problems, such as cell toxicity, parenteral route, and time of treatment. Ozone emerges as an option to accelerate the standard treatment due to the immunomodulatory, antioxidant, and wound healing activity reported in the literature. This work aimed to evaluate the efficacy of aqueous ozone as an adjuvant to the standard treatment of cutaneous lesions caused by Leishmania amazonensis in an experimental model. For in vivo experiments, mice were randomly distributed in 6 groups, which were infected with L. amazonensis and treated in five different schedules using the standard treatment with Glucantime® with or without aqueous ozone. After the last day of treatment, the animals were euthanized and were analyzed: the thickness of lesions; collagen deposition, the parasitic burden of the lesions; blood leukocyte number; NO; and cytokine dosages and arginase activity from peritoneal macrophages. All treated groups showed a decrease in the lesion, but with a significative deposition of collagen in lesions with local ozone treatment. The parasite burden showed that ozone enhanced the leishmanicidal activity of the reference drug. The reduction of NO production and blood leukocyte count and increases in the arginase activity showed an immunomodulatory activity of ozone in the treated animals. Thus, ozone therapy has been shown to work as an adjuvant in the treatment of Leishmania lesions, enhancing leishmanicidal and wound healing activity of standard treatment.

Abstract
BACKGROUND Fracture healing is one of the important issues in medicine and veterinarian medicine. A new technique should be detected with fewer side effects which improves the speed of the healing. This study was conducted to evaluate the effect of topical ozonated oil on the healing of bone defects created in rat calvarium. METHODS Defects of 7 mm were induced with a trephine in the calvaria of 45 male Sprague-Dawley rats. The animals were divided into 3 groups, and the defects in each group were filled with ozonated oil, olive oil, or left empty as a control. The animals were euthanized at 3 different time points (14, 28, and 42 days post-operation). Histological and serological (alkaline phosphatase) assessments were carried out on 14, 28, and 42 days post-operation. RESULTS On 14 and 28 days post-operation, in the edges of the defect, there was a significant difference between the ozonated oil group and olive oil as well as control groups (P ≤ 0.05). However, in the center of the defect, there were no statistically significant differences between the 3 groups (P > 0.05). On day 42, in the edges and center of the defect, there was a significant difference between the ozonated oil group and olive oil as well as control groups statistically (P ≤ 0.05). CONCLUSION The results of this study indicate the potential efficacy of ozonated oil as a bone substitute in a rat calvarial defect model.

Abstract
BACKGROUND Management of erosive Oral Lichen Planus (eOLP) is challenging. Currently, topical corticosteroids are widely used as first-line therapy, but they might be associated with side-effects and incomplete clinical response. Among non-pharmacological strategies, ozone at low medical concentration has proven to induce a mild activation of protective anti-oxidant pathways, thus exerting therapeutic effects in many inflammatory diseases. The aim of this randomized controlled study was to investigate the effectiveness of ozonized water in association with conventional topical corticosteroids for the treatment of eOLP. MATERIAL AND METHODS Fifty-one patients were included in the study and randomized into 2 groups: study group (n=26) included patients receiving ozonized water treatment; control group (n=25) included patients receiving placebo treatment (i.e. double-distilled water). Treatment protocol consisted of 1-minute oral rinses, repeated for 4 times, twice a week for 4 weeks. All patients received conventional corticosteroid topical therapy (betamethasone soluble tablets, 2 rinses/day for 4 weeks). Assessment of size of lesions, sign and pain scores was performed before treatment, after 2 weeks of treatment (T1) and at the end of 4-week treatment (T2). Efficacy Index (EI) of treatment, candidiasis and relapse rates were also recorded. RESULTS All patients experienced significant improvement of sign and pain scores with a higher rate of improvement in ozone-treated group (T1 improvement rates: Thongprasom 92.2% vs 28%; VAS pain 76.9% vs 32%; p<0.05). Pain and size reduction were significantly higher in ozone-treated group both at T1 and T2 (p<0.05). Ozone-treated group showed a higher EI at every time point (T0-T2: 72.77% vs 37.66%, p<0.01). Candidiasis (32% vs 11.5%) and relapse (40% vs 34.6%) rates were higher in control group, however the differences were not statistically significant. CONCLUSIONS Within the limitations of this study, ozonized water seems to be effective as an adjunct therapy, in combination with topical corticosteroids, for the treatment of eOLP.

Abstract
OBJECTIVE The objective of this study was to evaluate the effects of ozone therapy on wound healing formed experimentally in the oral cavity of rats. DESIGN Two surgical wounds were generated on the cheeks of 24 Wistar rats, bilaterally. Half of the animals were submitted to ozone therapy on both wounds (experimental group) and the other half received no treatment (control group). In the experimental group, wounds were exposed to ozone gas 1, 2 or 3 (60 μg/mL) times. Evaluation of wound healing of the buccal mucosa was followed for 1, 3 and 7 days. The distribution of neutrophils, fibroplasia and angiogenesis were analyzed. Samples were classified in a healing numerical scale according to the inflammatory intensity. Data were submitted to Mann-Whitney and Kruskal-Wallis tests (α = 0.05). RESULTS On day 1, wounds were similar in both groups, lesions were open and bloody with slightly minor bleeding in the ozone therapy group. On day 3, the group with ozone therapy was almost all refurbished and with higher angiogenesis, while the control group still had more bloody points and lower blood vessels. On day 7, both wounds were remodeled, with higher fibroplasia in the group that received ozone therapy. CONCLUSION It can be concluded that ozone therapy was effective in improving angiogenesis and fibroblasts count in the buccal mucosa of rats.

Abstract
Purpose This study aims to investigate the antifungal activity and mechanism of action of ozonized oil eye drops in liposomes (Ozodrop), commercialized as eye lubricant for the treatment of dry eye syndrome and eye inflammation. The activity was tested against four clinical Candida species: C albicans, C glabrata, C krusei, and C orthopsilosis. Methods The antifungal activity of the eye drop solution was ascertained by microdilution method in accordance with EUCAST obtaining the minimum inhibitory concentration for Ozodrop. The mechanism of action was further investigated in C albicans by measuring cell vitality, intracellular reactive oxygen species production, levels of cellular and mitochondrial (∆Ψm) membrane potential, and the extent of membrane lipid peroxidation. Results All Candida isolates were susceptible to Ozodrop with minimum inhibitory concentration values ranging from 0.195% (v/v) for C glabrata to 6.25% (v/v) for C orthopsilosis. After 1 hour of exposure at the minimum inhibitory concentration value about 30% of cells were killed, reaching about 70% at the highest Ozodrop value. After Ozodrop exposure, C albicans showed cell membrane depolarization, increased levels of lipid peroxidation, depolarized ∆Ψm, and increased reactive oxygen species generation. Conclusions The significant increases in reactive oxygen species production cause the accumulation of reactive oxygen species-associated damages leading to progressive Candida cell dysfunction. Translational Relevance The antifungal activity of Ozodrop was demonstrated at concentrations several times lower than the concentration that can be retrieved in ocular surface after its application. The antifungal activity of the eye drops Ozodrop would represent an interesting off-label indication for a product basically conceived as an eye lubricant.

Abstract
Background: Diabetes is a disease that affects people worldwide, including in Indonesia. The prevalence of diabetes in Indonesia is increasing from year to year. One of the most devastating complications of diabetes mellitus is diabetic ulcers, which is a limb-threatening complication. Over the past few decades, ozone generated using plasma medical technology has been investigated as an agent that helps wound healing. This study aims to evaluate the effects of topical ozonated virgin coconut oil (VCO) in a diabetic wound mouse model. Methods: This study was an experimental study with a post-test control design. An ulcer wound model was made in 50 diabetic male Wistar mice, divided into five groups, and a control group of 10 non-diabetic mice. The control groups were given conventional therapy only and the treatment groups were also given topical ozonated VCO with different flow durations (0 min, 90 min, 7 h, 14 h). Macroscopic appearance and wound contraction were observed. HSP90β, VEGF-A, EGF, bFGF and CD34 levels were measured from the immunostained slices of wound margins. Results: The reduction of wound length was proportionally related to the duration of ozone flow. Ozonated VCO with a longer duration of ozone flow healed the wound more quickly and had the shortest wound length. VCO with ozone flow for 14 hours (16837.10 µm) had the biggest reduction in wound length compared to other groups. The wounds treated with ozonated VCO showed an increase in HSP90β, VEGF-A, EGF, bFGF and CD34 levels that correlated to improved wound healing. A longer period of treatment resulted in higher levels of wound healing biomarkers compared to shorter therapeutic durations. Conclusions: Topical ozonated VCO improved the wound healing process in a diabetic ulcer mouse model by improving macroscopic wound appearance and increasing levels of wound healing biomarkers.

Abstract
Mammalian sirtuins (SIRTs 1-7) are a family of NAD+-dependent deacetylases with distinct subcellular localization and biological functions that regulate various important cellular processes. Among these, SIRTs -3, -4 and -5 are located in the mitochondria and have been implicated in caloric restriction, oxidative stress, aging and various human diseases. Emerging evidence has found dysregulation of mitochondrial sirtuins in multiple dermatological conditions, including responses to ultraviolet radiation (UVR), suggesting their importance in maintaining skin health. In this review, we discuss the roles and implications of mitochondrial sirtuins in cutaneous cellular processes, and their emerging potential as a target for the management of skin diseases, including skin cancer. Among mitochondrial sirtuins, SIRT3 is the most studied and linked to multiple skin conditions and diseases (keratinocyte differentiation, wound healing, chronological aging, UVR and ozone response, systemic sclerosis, melanoma, basal cell carcinoma (BCC) and squamous cell carcinoma (SCC)). SIRT4 has been connected to keratinocyte differentiation, chronological aging, UVR response, alopecia, BCC and SCC. Further, SIRT5 has been associated with keratinocyte differentiation, melanoma, BCC and SCC. Overall, while there is compelling evidence for the involvement of mitochondrial sirtuins in skin, additional detailed studies are needed to understand their exact roles in skin and skin cancers.

Abstract
Wound tissue repair is a complex and dynamic process of restoring cellular structures and tissue layers. Improvement in this process is necessary to effectively treat several pathologies characterized by a chronic delayed wound closure, such as in diabetes, and the investigation of new approaches aimed to ameliorate the wound healing process is under continuous evolution. Recently, the usage of vegetable matrices in the form of ozonated oils has been proposed, and several researchers have shown positive effects on wound healing, due to the bactericidal, antiviral, and antifungal properties of these ozonated oils. In the present review, we intend to summarize the actual state of the art of the topical usage of ozonated oil in cutaneous wounds with special emphasis to the importance of the ozonated degree of the oil.

Abstract
Ozone therapy has been widely used to treat many skin diseases, including infections, allergic dermatosis, and skin ulcers. However, its efficacy as a treatment for psoriasis is unclear. In this study, we explored the clinical efficacy and the underlying molecular mechanisms of ozone therapy on psoriasis. We found that topical ozone treatment significantly decreased patients' psoriasis area and severity index (PASI) scores and the expression of psoriasis-associated cytokines in their peripheral blood CD4+ T cells. In the IMQ-induced psoriasis mouse model, topical ozone treatment significantly inhibited the formation of IMQ-induced psoriasis-like lesions and the expression of psoriasis-associated inflammatory factors. High-throughput sequencing confirmed that IMQ-induced activation of toll-like receptor 2 (TLR2)/ nuclear factor-κB (NF-κB) signaling pathway was significantly suppressed in psoriasis-like lesions after topical ozone treatment. Furthermore, the activation of spleen T helper (Th) 17 cells was blocked in the mouse model; this was associated with the downregulation of cytokines and NF-κB pathways upon topical ozone treatment. Ozone therapy can attenuate local inflammatory reactions and the activation of Th17 cells in psoriasis by inhibiting the NF-κB pathway. Our results show that ozone therapy is effective in treating psoriasis. We recommend further evaluations for its clinical applications.

Abstract
Psoriasis is a chronic immune‐mediated inflammatory dermatosis. Recently, ozone therapy has been applicated to psoriasis treatment; however, the mechanism by which ozone therapy improves psoriasis remains unclear. The excessive proliferation and the differentiation of basal keratinocytes have been considered critical issues during pathological psoriasis process, in which keratin 6 (KRT6) and KRT10 might be involved. In the present study, KRT6, IL‐17 and IL‐22 protein within psoriasis lesions was decreased, while KRT10 and Tp63 protein in psoriasis lesions was increased by ozone treatment in both patient and IMQ mice psoriatic tissues. In the meantime, ozone treatment down‐regulated KRT6 mRNA and protein expression while up‐regulated KRT10 mRNA and protein expression within IL‐22 treated primary KCs; the cell viability of KCs was suppressed by ozone treatment. Moreover, Tp63 bound to KRT10 promoter region to activate its transcription in basal keratinocytes; the promotive effects of ozone on Tp63 and KRT10 were significantly reversed by Tp63 silence. Both TP63 and KRT10 mRNA expression were significantly increased by ozone treatment in psoriasis lesions; there was a positive correlation between Tp63 and KRT10 expression within tissue samples, suggesting that ozone induces the expression of Tp63 to enhance the expression of KRT10 and the differentiation of keratinocytes, therefore improving the psoriasis. In conclusion, the application of ozonated oil could be an efficient and safe treatment for psoriasis; ozone promotes the differentiation of keratinocytes via increasing Tp63‐mediated transcription of KRT10, therefore improving psoriasis.

Abstract
The search for a wide spectrum of antimicrobial agents that can avoid resistance while maintaining reasonable side effects has led to ozonated oils experiencing an increase in scientific interest and clinical applications. The treatment of vegetable oils with ozone leads to the creation of a reservoir of ozone that slowly releases into the skin thanks to the fact that ozone can be held as ozonides of unsaturated fatty acids. Interest in the use of ozonated oils has meant that several ozonated-vegetable-oil-containing products have been commercialized as cosmetic and pharmaceutical agents, and in innovative textile products with antibacterial activity. New approaches to the delivery of ozonated oils have very recently appeared in an attempt to improve their characteristics and reduce drawbacks, such as an unpleasant odor, high viscosity and undesired effects on skin, including irritation and rashes. The present review focuses on the current status of delivery agents that use ozonated oils as antimicrobial agents in topical (dermal, skin, and soft tissues) treatments. Challenges and future opportunities for these delivery systems will also be discussed.

Abstract
A mutual link between somatic and visceral neural pathways is known in medicine. This study addresses therapeutic effectiveness of an integrated rehabilitative approach of thermal aquatic environment, combined with neuromuscular manual stimulation, on activation of afferent sensory visceral and somatic efferent neuronal motor pathways in different pathologies of neuromuscular motor and respiratory systems. The study included 63 patients subjected to a protocol consisting of hydroponic treatment, hydrokinesitherapy associated with ozonized vascular pathway, and mud therapy associated with cardiorespiratory treatment performed in aquatic environment and aided by neuromuscular manual therapy. The therapeutic protocol consisted of rehabilitation sessions 5 days a week for 2 months. The outcome measures were spirometry tests and the following evaluation instruments: Tinetti Gait and Balance assessment scale, Functional Independence Measurement, visual analogue scale, and the EQ-5D-5 L instrument. The tests were applied before and after the protocol completion. The findings demonstrate a general increase in patients' everyday living autonomy and quality of life, with a particular improvement in respiratory function tests. We conclude that the integrated thermal approach holds promise in therapeutic rehabilitation of disabilities.

Abstract
Ozone is an important oxidant in the environment. To study the nature of multiphase ozonolysis, an unsaturated triglyceride, triolein, of the type present in skin oil, biological membranes, and most cooking oils was oxidized by gas-phase ozone on a surface. A high-performance liquid chromatography/electrospray ionization mass spectrometry (HPLC-ESI-MS) method was developed for analyzing triolein and its oxidized products. Upon exposure to ozone, the decay of thin coatings of triolein was observed, accompanied by the formation of functionalized condensed-phase products including secondary ozonides (SOZ), acids, and aldehydes. By studying the reaction kinetics as a function of average coating thickness and ozone mixing ratio, we determined that the reactive uptake coefficient (γ) is on the order of 10-6 to 10-5. It is also concluded that the reaction occurs in the bulk without a major interfacial component, and the reacto-diffusive depth of ozone in the triolein coating is estimated to be between 8 and 40 nm. The specific nature of the reaction products is affected by the reactions of the Criegee intermediate formed during ozonolysis. In particular, although an increase in the relative humidity to 50% from dry conditions has no effect on the kinetics of triolein decay, the yield of SOZs is significantly depressed, indicating reactions of the Criegee intermediates to form hydroperoxides. Once formed, the SOZ products are thermally stable over periods of at least 48 h at room temperature but decomposition was observed under simulated outdoor sunlight, likely forming organic acids. From an environmental perspective, this chemistry indicates that SOZs and other oxygenates will form via ozonolysis of oily indoor surfaces and skin oil.

Abstract
The "third-generation" cooking oil based drug, named plasma activated oil (PAO), is produced in cheap olive oil by a single-step, room temperature, energy-efficient, and environment-friendly dry plasma-enabled process. The streamer-surface discharge generates abundant energetic species, atomic oxygen at the plasma-oil interface. The otherwise challenging dissociation of C═C double bonds by energetic species and oxidation by the plasma generated atomic oxygen is the key mechanism to produce the H2O2 active species and carboxylic acid in the PAO. It is shown that the peroxide value and acid value of PAO are 7.5 times and 57% higher than those of the traditional ozonated oil, respectively. Different from plasma activated water whose shelf life was less than 1 week, PAO could be stored at room temperature for at least 3 months, and a shelf life of up to 1 year is expected. We further reveal that the PAO can not only sterilize the wound, but also promote more release of growth factor such as VEGF and CD34; therefore, the wound healing of PAO is 28.5% faster than that of the control group.

Abstract
OBJECTIVES Leishmaniasis is one of the main health problems in developing countries, caused by intracellular protozoan parasites of the Leishmania genus. Although research has been successful in discovering vaccines and anti-parasitic drugs like antimony compounds, their side effects like high toxicity, prolonged regeneration, etc., have raised the replacement importance of natural products with antioxidant and antibacterial properties. It can be said that an appropriate alternative to this is the ozonated olive oil. Ozone by introducing O2 in involved tissues and bloodstream could degrade parasite amastigotes and lead to cleared leishmaniasis infections. So, the present study aimed to evaluate the effect of ozonated olive oil in Iranian leishmaniasis patients compared to glucantime, a choice drug for the treatment of Leishmaniasis. MATERIALS AND METHODS Thirty patients with confirmed leishmaniasis lesions were included and divided into two groups, 15 cases as control and 15 cases as test with lesions of 30-50 mm2 in diameter. The control group received glucantime intralesionally and the test group ozonated olive oil plus glucantime, 2 times daily. RESULTS The mean of lesion size was (50.94±33.20) before and (15±14.34) after treatment in control (P<0.00) and (50.88±31.74) before and (9.93±14.18) after treatment in the test group (P<0.00). Moreover, the mean course of therapy was 10.4(±1.84) weeks and 8.93(±2.15) weeks in control and test groups, respectively (P=0.636). Significant differences were reported in lesion size after treatment between the two groups (P<0.00). CONCLUSION Data suggested ozonated olive oil can have synergistic effects with glucantime in the treatment of cutaneous leishmaniasis.

Abstract
Diabetic foot ulcers (DFU) are a burden to the diabetic community. With increasing medical bills, to unsuccessful treatment, those suffering from DFUs can use alternative therapeutics. First seen in the mid-1800s, ozone (O3) is thought to be unstable, due to inherent molecular nature. With the help of pharmaceutical science, various O3 treatments have flourished in the medical community to help those suffering from DFUs. Promising results are seen through numerous studies. Usually, a mixture of both O2 and O3 is seen in pressurized machines as administered to the foot ulcer. Foot ulcers, specifically DFUs, need to be assessed, cleaned, and treated as fast as possible for the fastest results. Results such as amputation can be seen if the foot is not attended to as soon as possible. With fast growing clinical trials in O3 therapy and quick administration of the O3, O3 therapy may be on the rise to be at the forefront of treating DFUs. Compelling evidence is seen in clinical trials, but more must be done to fully understand the role of O3 in DFUs.

Abstract
Chronic wounds present a significant burden to the health care system and the patient. Ozone therapy has been proposed as a treatment for chronic wounds, potentially acting by eliciting mild oxidative stress or disinfection. The purpose of this systematic review is to evaluate the potential benefits and harms of ozone therapy as an advanced care intervention for chronic wounds. Studies were extracted from Google Scholar, PubMed, the Cochrane Library, and reference lists. General inclusion criteria included English-language randomised human trials reporting the use of ozone therapy in the topical treatment of chronic wounds. Primary outcome data included the extent of chronic wound healing, and secondary outcomes included adverse effects. Studies were assessed for level of bias and data quality. Nine studies (n = 453 patients) matched the inclusion criteria and underwent meta-analysis. Overall, there was a significant improvement in wound closure with ozone therapy. Results consistently favour the application of ozone as a treatment for chronic wounds; however, there is no conclusive evidence of ozone therapy as superior compared with standard treatments. Compared with standard care, ozone therapy as an advanced wound care treatment may improve the proportion of chronic wounds healed in a shorter amount of time, but further research is required.

Anti-Inflammatory and Tissue Regenerative Effects of Topical Treatment with Ozonated Olive Oil/Vitamin E Acetate in Balanitis Xerotica Obliterans. Molecules 2018; 23:E645.

Abstract
Balanitis xerotica obliterans (BXO) is a chronic inflammatory skin disorder, considered the male genital variant of lichen sclerosus. Anti-inflammatory drugs are commonly used in BXO. We evaluated the effects of an innovative formulation of ozonated olive oil with vitamin E acetate (OZOILE®) on the inflammatory status and tissue remodeling in male children with BXO. The mRNA transcripts of proteins involved either in inflammation or in dynamics of tissue regeneration were analyzed by quantitative real-time PCR, in foreskins affected by BXO removed from patients untreated or treated with OZOILE® cream for 7 days before circumcision. We found a significant reduction in mRNA levels of IL-1β, TNF-α, INF-γ, transglutaminase 2 and NOS2 in foreskins treated with OZOILE® in comparison to untreated ones (p < 0.001). No significant differences were observed in NF-κB activation in the specimens obtained from treated and untreated patients. Hence, OZOILE® treatment up-regulated hypoxia-inducible factor (HIF)-1alpha, vascular endothelial growth factor (VEGF) and E-cadherin gene expression (p < 0.001). The treatment with OZOILE® showed effective results in children affected by BXO by reducing the inflammatory process and stimulating mechanisms for tissue regeneration of the foreskin. A randomized clinical trial on a large number of children affected by BXO might be useful to verify the efficacy of topical treatment with OZOILE®.
