Laser Photobiomodulation and Antimicrobial Photodynamic Therapy in the Treatment of Ovine Otitis

Background: Otitis is a severe inflammation of the skin of the auditory canal which can impact animals of all ages. In sheep, this disease can occur in isolated cases or in the entire flock. Laser photobiomodulation can be used in combination with medication or as single therapy and the effects are analgesia, modulation of the inflammatory process, edema reduction, tissue restoration and stimulation of local microcirculation. Antimicrobial photodynamic therapy stands out as a promising alternative to antimicrobial drugs for the treatment of localized infections. This study aimed to report the use of laser phototherapies on a sheep with bacterial otitis.Case: A case of bacterial otitis in a 4-year-old sheep, Dorper, was treated at the Veterinary Hospital of the State University of Santa Cruz. In the anamnesis, the owner reported that the patient presented crusts in the auricular pavilions, and had been medicated with oxytetracycline 20%, administered intramuscularly, for two days and the crusts cleaned with iodine 10%, but the animal did not present clinical improvement. On physical examination, the animal presented constant head swaying, edema of the ears, otalgia, enlarged parotid lymph nodes and ear wounds. No ear discharge was observed, and the initial diagnosis was aural hematoma. The treatment prescribed was laser photobiomodulation for three consecutive days. The lesions were irradiated with a diode laser with a power of 0.1 W, irradiance of 3.5 W/cm2, continuous emission, spot area of 0.028 cm2, wavelength of 808 nm, energy of 4J/point, and fluency/point of 142.8J/cm2, with seven points on the external surface and four points on the internal surface of both ears. Two points were also targeted on the parotid lymph nodes with infrared laser (λ = 808 nm), with energy of 2J/point. On the fourth day of hospitalization, there was a reduction in lesions, decreased edema and absence of pain and on the sixth day of hospitalization, the patient presented mucopurulent otorrhea. The material from the auricular pavilions was collected for cytological examination, confirming the clinical diagnosis of bacterial otitis. Two sessions of Antimicrobial Photodynamic Therapy (aPDT) were performed with an interval of 48 hours, with application of 0.01 % methylene blue, pre-irradiation time of five minutes and irradiation with diode laser with a power of 0.1 W, 660 nm wavelength and 9J/point energy. On the 10 th day after the start of the treatment, there was no pain, healing of ear wounds, and no otorrhea. An additional photobiomodulation session was performed on the unhealed wounds in the auditory canal with red laser (λ = 660nm), on 5 points with an energy of 1J/point. On the 15th day, the left ear was healed and the right ear presented otorrhea, and a further session of aPDT was performed. On the 17th day after starting treatment there was no secretion and all lesions were healed. The patient was subsequently monitored for one month, showing no change or relapse.Discussion: Laser photobiomodulation treatment and antimicrobial photodynamic therapy were efficient in treating bacterial otitis without the use of antibiotics, promoting clinical improvement and patient well-being, making it an alternative to conventional treatment. After searches on the Pubmed, Scielo and Escopus databases using photobiomodulation and antimicrobial photodynamic therapy in sheep otitis as descriptors, this is believed to be the first report on the use of laser phototherapy in sheep otitis. Further studies are needed to establish the dosimetry and frequency of the sessions, as, besides considering animal well-being, this species is an excellent model for human experimentation

VARIAÇÕES MICROCLIMÁTICAS DE ÁREAS URBANAS EM BIOMAS NO ESTADO DE MATO GROSSO: CUIABÁ E SINOP

O estado de Mato Grosso, com extensão de 906 mil km², possui importância significativa devido a variedade de biomas, entre eles, Cerrado e floresta Amazônica. Sabe-se que a vegetação tem grande influência nas características microclimáticas locais. Exposto isso, o objetivo geral deste estudo foi analisar as variações microclimáticas de áreas urbanas nesses diferentes biomas do estado de Mato Grosso. Foram obtidos dados de radiação solar, temperatura do ar e umidade relativa do ar de estações microclimáticas fixas nos municípios de Cuiabá e Sinop, distantes entre si em 500 km, no ano de 2014. As variações de radiação solar, temperatura e umidade relativa do ar entre as áreas seguem a mesma sazonalidade. As temperaturas máximas ocorrem em setembro em ambas as cidades, enquanto as temperaturas mínimas ocorrem em julho para Cuiabá e junho para Sinop. Com relação a umidade relativa do ar média mensal, ambas possuem sua máxima em abril e mínima em agosto. As diferenças de energia solar incidente nas localidades, são maiores dentre junho e agosto devido as variações de nebulosidade e aerossóis presentes na atmosfera. Portanto a urbanização intensa do município de Cuiabá influencia diretamente nas condições climáticas do local

Perspectivas da Mauritia flexuosa como potencial agente anti-hipertensivo / Perspectives of Mauritia flexuosa as a potential anti-hypertensive agent

INTRODUÇÃO: As doenças cardiovasculares representam desafio de saúde pública, destacando-se a hipertensão arterial sistêmica (HAS), devido ao alto índice de incidência populacional. O buriti (Mauritia flexuosa (MF)) é uma palmeira, encontrada nas regiões norte, nordeste e centro oeste, abundante em carotenoides e polifenóis, sendo empregado, farmacologicamente, como agente cicatrizante e antibacteriano. OBJETIVO: Investigar as perspectivas da MF como potencial agente anti-hipertensivo. METODOLOGIA: Trata-se de uma revisão de literatura, realizada de dezembro/2021 a fevereiro/2022 através dos bancos de dados on-line: PubMed, Scielo e Lilacs, utilizando os descritores: Mauritia flexuosa, buriti, sistema cardiovascular e hipertensão, nas línguas inglesa e portuguesa. Os artigos selecionados atendem ao período de 2008 a 2016, abordando-se a relação da MF com o sistema cardiovascular (SCV). Os dados foram organizados e expressos em tabela, utilizando-se o programa Excel®. RESULTADOS: De 46 artigos encontrados, 6 foram selecionados. Nenhum estudo emprega o buriti como agente hipotensor e anti-hipertensivo. Entretanto, constatou-se que a MF é rica em substâncias químicas com potencial antioxidante, antitrombótica e anti-plaquetária, tais como o ß-caroteno e ácidos graxos. CONCLUSÃO: Há escassez de estudos acerca da ação da MF sobre o SCV. Contudo, os constituintes químicos da MF representam potente perspectiva anti-hipertensiva, necessitando estudos farmacológicos do seu papel na fisiopatologia da HAS

Background: Posttraumatic stress disorder consists of a set of symptoms that occurs in response to one or more traumatic events and can occur in postpartum, from traumatic situations related to the birth or to the baby’s health in the first days of life. It is important tracking the presence of birth trauma, but there is not available instruments in the Brazilian context for this purpose. Objectives: To present the cross-cultural adaptation of City Birth Trauma Scale (BiTS) into Brazilian portuguese. Methods: Cross-cultural adaptation involved independent translations, synthesis,back-translation, and submission to the original author’s appreciation. After the scale was subjected to face validity, followed by a pilot study with postpartum mothers. Results: All steps were performed for the cross-cultural adaptation. Regarding face validity, items evaluated concerning different types of equivalence, presented satisfactory agreement values (≥4.20). Most of the expert’s suggestions were followed, being the main ones related to adjustments in prepositions, pronouns and verbal subjects. Pilot study showed that the mothers had been able to understand and respond to the instrument without adjustments. Discussion: BiTS’s Brazilian version proved to be cross-culturally adapted, ensuring the possibility of intercultural data comparison from the semantic, idiomatic, cultural, and conceptual perspectives. New studies are being conducted to attest its psychometric adequac

Social distancing measures to control the COVID-19 pandemic: potential impacts and challenges in Brazil.

The COVID-19 pandemic has challenged researchers and policy makers to identify public safety measures forpreventing the collapse of healthcare systems and reducingdeaths. This narrative review summarizes the available evidence on the impact of social distancing measures on the epidemic and discusses the implementation of these measures in Brazil. Articles on the effect of social distancing on COVID-19 were selected from the PubMed, medRXiv and bioRvix databases. Federal and state legislation was analyzed to summarize the strategies implemented in Brazil. Social distancing measures adopted by the population appear effective, particularly when implemented in conjunction with the isolation of cases and quarantining of contacts. Therefore, social distancing measures, and social protection policies to guarantee the sustainability of these measures, should be implemented. To control COVID-19 in Brazil, it is also crucial that epidemiological monitoring is strengthened at all three levels of the Brazilian National Health System (SUS). This includes evaluating and usingsupplementary indicators to monitor the progression of the pandemic and the effect of the control measures, increasing testing capacity, and making disaggregated notificationsand testing resultstransparentand broadly available
