The aims of this study were to test a locally applied carvacrol gel and determine its efficacy preventing alveolar bone loss in experimental periodontitis in rats by regular methodology to validate applicability the atomic force microscopy (AFM) as a novel morphology method on this model. Wistar rats were subjected to ligature around second, upper-left molars. Animals were treated carvacrol gel topically (CAG), immediately after Experimental Periodontitis Disease induction for 1' three-times/day for 11 days. A vehicle gel was utilized as control. The periodontium and the surrounding gingivae were examined at regular histopathology and by AFM method; the neutrophil influx into the gingivae was also assayed using myeloperoxidase activity. The bacterial flora was assessed through culture of the gingival tissue. Alveolar bone loss was significantly inhibited by CAG group compared to the Vehicle (V) group, the carvacrol gel treatment reduced tissue lesion at histopathology, with preservation of the periodontium, coupled to decreased myeloperoxidase activity in gingival tissue and also prevented the proliferation of periodontal microorganisms and the weight loss. The GAC treatment preserved alveolar bone resorption and showed anti-inflammatory and antibacterial activities in experimental periodontitis. Topographical changes in histological sections were seen bringing into high relief the periodontal structures, being a simple and cost-effective method for periodontal evaluation with ultrastructural resolution.

Objective: To assess the effect of virtual reality in pain relief during chronic wound dressing change. Method: This is an experimental study carried out with 17 participants, in a stomatherapy clinic in Ceará, Brazil, from June to December 2019, using the virtual reality glasses Oculus Go®. Sociodemographic and clinical information, as well as of lifestyle, and characteristics of the lesions were collected. A faces scale and a visual analogue scale were used for pain assessment, behavioral aspects assessment, satisfaction, and discomfort with Oculus Go®. The Chi-square, McNemar, and Wilcoxon tests were used. The study was approved under opinion No. 2.649.144/2019. Results: There was a reduction in pain during dressing change with Oculus Go®. Participants with Oculus Go® manifested less pain during (p < 0.001) and after (p < 0.001) dressing change; and had lower heart rate before (p = 0.044) and after (p = 0.001) the procedure. There were significant differences between groups in systolic (p = 0.012) and diastolic (p = 0.004) blood pressure values after dressing. Virtual reality did not cause any discomfort and participants were satisfied. Conclusion: Virtual reality showed positive effects in pain relief during chronic wound dressing change.

Objective: to describe Covid-19 mobile applications available for download on smartphones. Method: a cross-sectional study with 52 mobile applications on Covid-19, obtained from virtual stores for smartphones with Android and iOS operating systems. Fisher's exact test and Cramér's V were used. Results: of the applications, 45 (86.6%) were developed in 2020, 51 (98.1%) were free, and 49 (94.2%) did not have accessibility for people with disabilities. It was observed that, in 23 countries, 17 (32.7%) applications in English and 14 (26.9%) in Portuguese were created, with a choice of 11 languages, relating to nine subthemes on Covid-19, the majority on “case monitoring” and “symptoms, prevention, and care”, with 17 (32.7%) each. There was an association between the target audience and the subtheme of “symptoms, prevention, and care”, and between patient monitoring and professional training. Conclusion: Covid-19 mobile applications were available in countries on five continents, in the main languages of communication and free of charge; however, with limited accessibility for people with disabilities.

Objective to analyze scientific evidence on the efficacy of cloth masks in preventing COVID-19 and other respiratory infections. Method integrative literature review based on the following guiding question: What is the efficacy of cloth face masks in absorbing particles that cause respiratory infection? The search was conducted in eight electronic databases, without any restriction in terms of language or period. Results low coverage cloth face masks made of 100% cotton, scarf, pillowcase, antimicrobial pillowcase, silk, linen, tea towel, or vacuum bag, present marginal/reasonable protection against particles while high coverage cloth masks provide high protection. Conclusion cloth face masks are a preventive measure with moderate efficacy in preventing the dissemination of respiratory infections caused by particles with the same size or smaller than those of SARS-CoV-2. The type of fabric used, number of layers and frequency of washings influence the efficacy of the barrier against droplets.

Objetivou-se descrever a vivência de familiares de pacientes atendidos em uma Unidade de Emergência de Fortaleza-Ceará acerca de sua colaboração nas atividades e dificuldades vivenciadas. Estudo descritivo, com abordagem qualitativa, foi desenvolvido com 34 familiares acompanhantes de pacientes que se encontravam em observação. Os dados foram coletados por meio de entrevistas com roteiro semiestruturado no período de outubro e novembro de 2010 e a análise foi feita de acordo com a temática de conteúdo. Os resultados denotam déficit de aprendizagem e de informações acerca do diagnóstico, tratamento e cuidados prestados ao paciente. As dificuldades vivenciadas referiram-se à comunicação, infraestrutura, privacidade e poluição sonora. Acredita-se que a equipe interdisciplinar e os dirigentes possam sanar as dificuldades por meio de ações administrativas, organizacionais e educativas.
