RESUMO

Acute or chronic inflammatory reactions aim to control lesions, resist to pathogens attack and repair damaged tissue. The therapeutic administration of ozone known as ozone therapy appears as a possible treatment for tissue repair, as it promotes the healing of wounds. It has bactericidal, antiviral and antifungal properties and has been used as a therapeutic resource to treat inflammation. The objective was to carry out an integrative review regarding the use of ozonated oil in acute and chronic inflammations. The keywords "ozone therapy," "inflammation" and "ozone" were used in the Portuguese, Spanish and English languages. The paper selection was based on inclusion and exclusion criteria. In total, 28 articles were selected. It has been seen that ozonated oil is effective in healing cutaneous wounds. The beneficial effects are due to the healing of wounds, due to the reduction of microbial infection, debridement effect, modulation of the inflammatory phase, stimulation to angiogenesis as well as biological and enzymatic reactions that favor the oxygen metabolism, improving the wound cicatrization. In addition to promoting healing, ozonated oil reduces symptoms related to skin burns, prevents post-lesion hyperpigmentation, and reduces the pain of aphthous ulcers. Therefore, ozonated oil represents an effective and inexpensive therapeutic alternative that must be implanted in the public health system.

RESUMO

Purpose: We aimed to evaluate the effect of blueberry extract and microparticles (MP) on sunscreen performance of multifunctional cosmetics. Octocrylene (OCT), benzophenone-3 (BENZ-3) and Tinosorb® M (MBBT) were employed as UV filters. Methods: An in-silico modeling was used to determine the UV filters concentrations to obtain high values of sunscreen protection factor (SPF) and UVA protection factor (UVA-PF). MBBT and blueberry-loaded microparticles (MPMB+B) and MBBT-loaded microparticles (MPMBBT) were prepared by spray-drying. OCT and BENZ-3 were added in the oil phase of cosmetics. Cosmetics A and B contained MPMB+B and MPMBBT, respectively, and cosmetic C was prepared without MP. Characterization, physicochemical stability and in vitro SPF was performed. UV filters distribution in human stratum corneum (SC) for each cosmetic was performed. Anti-oxidant activity of blueberry extract was evaluated. Results: Sunscreen combination with the highest SPF was selected for formulations. Formulations A and B maintained their rheological behavior over time, unlike formulation C. In-vitro SPFs for formulations A, B and C were 51.0, 33.7 and 49.6, respectively. We also developed and validated a method for analysis of the UV filters by HPLC/ PDA suitable for the in-vivo assay. In Tape stripping test, MBBT showed SC distribution similar for all cosmetic formulations. OCT and BENZ-3 distribution to formulation A and C was also similar. Blueberry extract showed antioxidant capacity of 16.71 µg/mL equivalent to vitamin C. Conclusion: Cosmetics containing MPs presented better physical stability. Blueberry increased the photoprotective capacity of the formulations and added extra benefits due to its anti-oxidant and anti-aging properties.

RESUMO

Midazolam (MDZ) is the first choice in palliative sedation, and commonly used in sleep induction in anesthesia, with rapid onset of action. However, monitoring of the level of sedation in patients is not accurate. We developed and validated a bioanalytical method to detect MDZ in plasma using high-performance liquid chromatography (HPLC) coupled to a photodiode array detector (PDA) for future monitoring of sedation. MDZ was extracted by solid-phase extraction (SPE). Analyses were performed on a C18 column, using 0.05% triethylamine and acetonitrile as mobile phase, analyzing at 220 nm. Recovery was evaluated by comparing extracted and nonextracted solutions. Precision, accuracy, linearity, limits of detection (LD) and quantification (LQ), specificity and selectivity were determined. The mean recovery obtained by SPE was 101.03%. The method was linear in the range 1.0-50.0 µg/mL. The LD and LQ were, respectively, 0.43 and 1.43 µg/mL. The specificity of the MDZ peak was adequate. The method was able to detect MDZ among other drugs. Plasma anticoagulants showed no interference with the drug detection. The bioanalytical method using HPLC-PDA and SPE was successfully validated and showed linearity, precision, accuracy, specificity and high sensitivity for detection of MDZ in human plasma.

RESUMO

ABSTRACT BACKGROUND AND OBJECTIVES: Osteoarthrosis affects 85% of the population over 75 years of age. It is divided into primary and secondary, however despite the knowledge at the molecular level the treatments are not yet fully effective. However, ozone therapy emerges as an alternative therapy, which is low cost and seems effective in the treatment of chronic pain. The objective of this study was to evaluate the current evidence to support or to refute the use of ozone therapy in the treatment of patients with osteoarthritis. CONTENTS: Systematic review using the keywords "ozone therapy", "ozone", "osteoarthritis", "arthritis", "randomized", "controlled" and "meta-analysis". The selection of publications was based on inclusion and exclusion criteria. In total, 9 articles were used. Among the 9 articles found regarding ozone therapy in osteoarthritis, 7 of them clearly show the benefits of ozone. The concentrations of ozone used in the studies ranged from 20µg/mL to 15g/mL. The route of administration was intra-articular and rectal insufflation. The frequency of use was, on average, 1 to 3 times a week and the treatment time was between 3 to 4 months in most of the studies. CONCLUSION: The use of ozone produces clinically relevant benefits in patients with osteoarthrosis. Therefore, ozone therapy in osteoarthrosis represents a low-cost, efficient therapeutic alternative that should be implemented in the country's Public Health, considering the prevalence of the disease.


RESUMO JUSTIFICATIVA E OBJETIVOS: A osteoartrose atinge 85% da população com mais de 75 anos. A mesma é dividida em primária e secundária, porém apesar do conhecimento a nível molecular, os tratamentos ainda não são totalmente eficazes. Entretanto, a ozonioterapia, é de baixo custo e parece efetiva no tratamento da dor crônica. O objetivo deste trabalho foi avaliar as evidências atuais que apoiem ou refutem o uso da ozonioterapia no tratamento de pacientes com osteoartrose. CONTEÚDO: Revisão sistemática, utilizando as palavras-chave: "ozone therapy", "ozone", "osteoarthritis", "arthritis", "randomised", "controlled" e "meta-analysis". A seleção das publicações foi feita a partir de critérios de inclusão e exclusão. Ao total foram utilizados 9 artigos. Dentre os 9 artigos encontrados a respeito de ozonioterapia na osteoartrose, 7 deles mostraram claramente os benefícios do ozônio. As concentrações de ozônio utilizadas nos estudos variaram de 20µg/mL a 15g/mL. A via de administração utilizada foi a intra-articular e a insuflação retal. A frequência do uso foi, em média, de 1 a 3 vezes por semana e o tempo de tratamento foi entre 3 a 4 meses na maior parte dos estudos. CONCLUSÃO: O uso do ozônio produz benefícios clinicamente relevantes em pacientes com osteoartrose, portanto a ozonioterapia na osteoartrose representa uma alternativa terapêutica de baixo custo, e eficiente, que deve ser implantada na Saúde Pública do país, tendo em vista a prevalência da doença.

RESUMO

Ozone helps decontamination environments due to its oxidative power, however present toxicity when it is in high concentrations, by long periods of exposition. This study aimed to assess the safety of ozone generator air purifier at concentrations of 0.05 ppm in rats exposed to 3 and 24 h/day for 14 and 28 days. No significant differences are observed between groups in clinical signs, feed and water intake, relative body weight gain and relative weight of organs, macroscopy and microscopy of lungs, and oxidative plasma assay. In this exposure regime, ozone does not cause genotoxicity and no significant changes in pulmonary histology indicative of toxicity. Ozone generated in low concentrations, even in exposure regimes above the recommended is safe, both acute and sub-acute exposition.

RESUMO

Objetivo ­ As infecções relacionadas à assistência à saúde são um problema mundial. A contaminação de pacientes através de mãos e objetos constitui-se na principal causa de infecção. O objetivo deste foi avaliar a contaminação bacteriana de terminais de computadores utilizados em diferentes setores do Hospital da Cidade de Passo Fundo-RS (HCPF), analisando o possível papel dos mesmos como fômites de infecção hospitalar. Métodos ­ Ao todo foram coletadas amostras de 221 terminais de computadores situados em setores críticos, semicríticos e não críticos. A coleta foi realizada com swab umedecido em solução salina, por fricção, sendo o material semeado em placas de Petri contendo ágar sangue e ágar MacConkey. As placas foram incubadas a 35-37ºC por 24 horas e as colônias presentes nos meios de cultura foram identificadas por técnicas convencionais. Resultados ­ Em 87,5% das amostras houve crescimento de micro-organismos, sendo identificados 11 tipos de bactérias. Cocos Gram-positivos foram os mais frequentes, com predominância de Staphylococcus coagulase-negativos (44,3%). As bactérias Gram-negativas foram responsáveis por apenas 4,2% dos casos. Não houve diferença significativa entre os três setores, embora Staphylococcus aureus tenha ocorrido com maior frequência nos setores críticos. Conclusão ­ Elevados níveis de contaminação foram observados nos terminais de computadores dos três setores, reforçando a importância da higienização desses equipamentos para evitar a transmissão cruzada de micro-organismos para os pacientes.


Objective ­ Infections related to health care is a global problem. Contamination of patients through hands and objects constitutes the main cause of infection. The objective of this study was to evaluate the bacterial contamination on computer terminals of different sectors of the Hospital da Cidade de Passo Fundo-RS (HCPF), to determine their possible role as sources of hospital infections. Methods ­ Samples were collected from 221 computer terminals located in critical, semi-critical, and non-critical sectors. The collection was made by rubbing the terminals with saline solution moistened swabs, then applying to blood and MacConkey agars in Petri dishes. After incubation at 35ºC to 37ºC for 24 hours, any resulting colonies in the medium were identified by conventional methods. Results ­ There was micro-organism growth in 87.5% of the samples, identified as 11 types of bacteria. Gram-positive cocci were the most frequent, predominantly Staphylococcus coagulase-negative. Gram-negative bacteria accounted for only 4.2% of the cases. There was no significant difference among the three sectors, although critical sectors had a higher frequency of Staphylococcus aureus. Conclusion ­ High levels of contamination were observed on computer terminals of all three sectors, re-enforcing the importance of equipment sanitation to prevent micro-organism cross transmission to patients.
