O dispositivo projetado visa colaborar com a sociedade, proporcionando um auxílio adicional para os deficientes visuais. O protótipo inicial projetado utiliza um Arduino Mini Pro, um sensor de ultrassom, uma bateria de celular e um motor vibra-call. O diferencial deste projeto é a utilização de componentes de baixo custo e a segurança a mais que o protótipo final vai proporcionar para locomoção (sem a necessidade de utilizar outros periféricos como fones, óculos e chapéus). Por fim, os resultados obtidos foram satisfatórios para os testes com não deficientes. Posteriormente, serão realizados testes com deficientes utilizando metodologias desenvolvidas por psicólogos, para realizar melhorias físicas e lógicas, para melhor adaptação às necessidades e anseios dos usuários deficientes e para redução de custos

Antimicrobial activity of sodium hypochlorite associated with intracanal medication for Candida albicans and Enterococcus faecalis inoculated in root canals

OBJECTIVE: The purpose of this study was to evaluate the action of sodium hypochlorite (NaOCl) associated with an intracanal medication against Candida albicans and Enterococcus faecalis inoculated in root canals. MATERIAL AND METHODS: Thirty-six human single-rooted teeth with single root canals were used. The canals were contaminated with C. albicans and E. faecalis for 21 days and were then instrumented with 1% NaOCl. The roots were divided into 3 groups (n=12) according to the intracanal medication applied: calcium hydroxide paste, 2% chlorhexidine (CHX) gel, and 2% CHX gel associated with calcium hydroxide. The following collections were made from the root canals: a) initial sample (IS): 21 days after contamination (control), b) S1: after instrumentation, c) S2: 14 days after intracanal medication placement; S3: 7 days after intracanal medication removal. The results were analyzed statistically by the Kruskal-Wallis test at 5% significance level. RESULTS AND CONCLUSIONS: Both 1% NaOCl irrigation and the intracanal medications were effective in eliminating E. faecalis and C. albicans inoculated in root canals

USE OF NANOCOMPOSITE HYDROGEL WITH N-UREA IN THE PRODUCTION OF EGGPLANT SEEDLINGS

The use of quality seedlings of eggplant is directly related to the success of their production, with polymers added to the substrate, which work as water conditioners, increase the water retention capacity, and provide better seedling quality. The study aimed to evaluate the use of nanocomposite hydrogel enriched with different proportions of N-urea in the production of eggplant seedlings. The experiment was conducted at the State University of Mato Grosso do Sul, Cassilândia, MS, Brazil, from June to August 2019, under sombrite® 30%. Five treatments were evaluated, using the commercial substrate, Carolina Soil®: 1) commercial substrate without hydrogel; 2) commercial substrate with 0.075g of pure hydrogel (0.00g of N-urea)/15 mL of a substrate; 3) commercial substrate with 0.075g of hydrogel and 10% N-urea/15 mL of a substrate; 4) commercial substrate with 0.075g of hydrogel and 20% N-urea/15 mL of a substrate, and 5) commercial substrate with 0.075g of hydrogel and 40% N-urea/15 mL of a substrate. The experiment was conducted with four replications of 25 seedlings. The emergence speed index, percentage of emergence, height, number of leaves, stem diameter, shoot dry matter, root dry matter, and total dry matter were evaluated, as well as the Dickson Quality Index. The data were subjected to analysis of variance (SPEEDSTAT statistical software) and grouping test of means. A regression analysis was performed to adjust equations for some of the variables. The best seedlings can be obtained using the dosage of 28.83% N-urea with 0.075g of hydrogel per 15 ml of the substrate, according to the DQI adjustment, which includes several traits of the seedlings, thus reflecting on its quality

Text mining analysis to understand the impact of online news on public health response: case of syphilis epidemic in Brazil

BackgroundTo effectively combat the rising incidence of syphilis, the Brazilian Ministry of Health (MoH) created a National Rapid Response to Syphilis with actions aimed at bolstering epidemiological surveillance of acquired, congenital syphilis, and syphilis during pregnancy complemented with communication activities to raise population awareness and to increase uptake of testing that targeted mass media outlets from November 2018 to March 2019 throughout Brazil, and mainly areas with high rates of syphilis. This study analyzes the volume and quality of online news content on syphilis in Brazil between 2015 and 2019 and examines its effect on testing.MethodsThe collection and processing of online news were automated by means of a proprietary digital health ecosystem established for the study. We applied text data mining techniques to online news to extract patterns from categories of text. The presence and combination of such categories in collected texts determined the quality of news that were analyzed to classify them as high-, medium-and low-quality news. We examined the correlation between the quality of news and the volume of syphilis testing using Spearman’s Rank Correlation Coefficient.Results1,049 web pages were collected using a Google Search API, of which 630 were categorized as earned media. We observed a steady increase in the number of news on syphilis in 2015 (n = 18), 2016 (n = 26), and 2017 (n = 42), with a substantial rise in the number of news in 2018 (n = 107) and 2019 (n = 437), although the relative proportion of high-quality news remained consistently high (77.6 and 70.5% respectively) and in line with similar years. We found a correlation between news quality and syphilis testing performed in primary health care with an increase of 82.32, 78.13, and 73.20%, respectively, in the three types of treponemal tests used to confirm an infection.ConclusionEffective communication strategies that lead to dissemination of high quality of information are important to increase uptake of public health policy actions

Mielomeningocele e anomalias associadas: uma série de casos e revisão sistemática

A mielomeningocele é uma malformação congênita grave do sistema nervoso central, representando um dos tipos mais complexos de defeitos do tubo neural. A condição é marcada pela exposição das meninges e, em alguns casos, da medula espinhal, através de uma abertura na coluna vertebral, desafiando tanto o prognóstico do paciente quanto as estratégias de tratamento. O presente estudo visa explorar os avanços recentes no diagnóstico, intervenções cirúrgicas e desfechos neurológicos associados à mielomeningocele, com foco particular na eficácia e segurança das abordagens atuais. Para isso, foi realizada uma revisão sistemática da literatura de 2016 a 2024 nas bases de dados PubMed (Medline), Cochrane Library e SciELO, aplicando critérios de inclusão e exclusão rigorosos para selecionar estudos que abordassem esses aspectos. Três estudos chave foram analisados, destacando-se pelas técnicas de diagnóstico antenatal, pela utilização de intervenções cirúrgicas inovadoras, como o fechamento fetal, e pelos cuidados pós-operatórios visando melhorias nos desfechos neurológicos. Os resultados indicam uma tendência positiva na melhoria da qualidade de vida dos pacientes, com avanços significativos no controle e na prevenção de complicações a longo prazo. No entanto, foi observada a necessidade de uma abordagem multidisciplinar no tratamento, integrando cuidados neurocirúrgicos, ortopédicos e reabilitativos. A mielomeningocele, apesar dos desafios, tem testemunhado progressos notáveis nas últimas décadas, sugerindo um futuro mais promissor para os pacientes afetados. Ainda assim, são necessários mais estudos para consolidar essas abordagens e otimizar as estratégias de tratamento na prática clínica

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
