Abstract The use of supplementary cementitious materials to replace Portland clinker is one of the most effective strategies adopted by cement companies to reduce CO 2 emission on large-scale. However, due to the limited availability of traditional materials, alternative options are being investigated. The main objective of this research is to evaluate the characteristics and effect of different replacement levels of cement by dregs and grits on compressive strength. The wastes were ground and particles smaller than 75 µm were used. Chemical and physical were performed to characterize the dregs and grits. For both wastes, replacement levels of 0, 5, 10, 20 and 30% of cement mass were evaluated in the mortar production. The water-cement ratio and superplasticizer admixture content were kept constant. In fresh state, the consistency index and incorporated air content were obtained. Mortars made with dregs had higher strength compared to grits due to the higher combined water content. The results showed that it is possible to replace up to 36% of cement with dregs to obtain a strength of 25 MPa; and 15% for 40 MPa.

Resumo Ouso de adições minerais em substituição ao clínquer Portland é uma das medidas mitigadoras de emissão de CO2, mais promissoras em larga escala, adotadas pelas cimenteiras. Dada a limitação de disponibilidade de algumas, materiais alternativos vêm sendo investigados. A presente pesquisa teve como objetivo caracterizar e avaliar o efeito de diferentes teores de dregs e grits em substituição parcial ao cimento na resistência à compressão. Os resíduos foram submetidos à moagem, utilizando-se partículas inferiores a 75 µm. Foram realizados ensaios para caracterização química e física dos dregs e grits. Para ambos os resíduos, foram analisados os teores de 0, 5, 10, 20 e 30% em substituição à massa de cimento na produção de argamassas. A relação água/finos e o teor de aditivo superplastificante foram mantidos constantes. No estado fresco, foram avaliados o índice de consistência e o teor de ar incorporado. As argamassas com dregs proporcionaram maior resistência em relação às com grits devido ao maior teor de água combinada. Os resultados mostraram que é possível substituir até 36% do cimento por esse resíduo para obtenção de resistência à compressão de 25 MPa e 15% para 40 MPa.

Abstract Background: One of the main adverse reactions of adjuvant radiotherapy for breast cancer is radiodermatitis. Objective: To assess the incidence of radiodermatitis in women with breast cancer, identify factors associated with its severity and determine the time at which this event occurs. Methods: Prospective cohort study in 113 women with breast cancer who were evaluated before radiotherapy and at every fifth session until the end of treatment. Logistic regression and Cox proportional regression model were used for the assessment of risk factors; P values < 0.05 were considered significant. Results: The incidence rate of radiodermatitis was 98.2% and it was demonstrated that for each additional point of the Body Mass Index (BMI), the chance of occurrence of grades II to IV radiodermatitis increases by 14% (OR = 1.14 [95% CI 1.04–1.26]; p = 0.004) and statin use increases the risk of more severe skin lesions by four-fold (OR = 4.27 [95% CI 1.11–16.42]; p = 0.035). The exclusive use of hydrogel for skin hydration was an independent factor in delaying the onset of radiodermatitis (HR = 0.55 [95% CI 0.36–0.82]; p = 0.004). Study limitations: The main limitation of this study was its external validity. The identified factors should be considered for services and populations similar to those in this study. Conclusions: There was a high incidence of radiodermatitis and its severity was related to higher BMI, statin use; there was a protective effect of hydrogel use.

Abstract: The proper choice of raw materials and manufacturing parameters for Cross Laminated Timber is essential to promote the proper bonding of the lamellas, aiming at their application in construction. However, few Brazilian species are currently used in the production of Cross Laminated Timber. The aim of this work was to characterize the bonding quality of four Brazilian reforestation species (Pinus elliottii (pino ellioti), Eucalyptus grandis (eucalipto), Toona ciliata (toona) and Acrocarpus fraxinifolius (lazcar)) in the manufacture of Cross Laminated Timber with two-component polyurethane adhesive and five different pressure levels (from 0,1 MPa to 1,3 MPa). Bonding quality was evaluated through delamination and glue line shear tests based on the European standard. Delamination was affected by the wood species, and the best adhesion occurred for the Cross Laminated Timber manufactured with Pinus elliottii (pino ellioti) and Acrocarpus fraxinifolius (lazcar) at the bonding pressure of 0,7 MPa. Cross Laminated Timber bonding pressure did not affect the percentage of wood in the shear test fractured surface, whereas higher density Cross Laminated Timber showed higher percentages.

Abstract Tea is identified as the second most consumed drink in the world, and its frequent intake is related to several benefits to human health, considering its antimutagenic, anticarcinogenic, antimicrobial, anti-inflammatory, antihistamine, diuretic, calming, and above all, antioxidant effects. These effects are often associated with the action of the phenolic compounds contained in these infusions. In Brazil, among the most consumed infusions are the teas of chamomile (Matricaria chamomilla L.), lemongrass (Cymbopogon citratus (D.C.) Stapf), lemon balm (Melissa officinalis L.), anise (Pimpinella anisum L.), yerba mate (Ilex paraguariensis A. St.-Hil), peppermint (Mentha piperita L.), and green/black tea (Camellia sinensis L.). Therefore, said popularity is the reason why the mentioned species were chosen to be evaluated on inflammatory enzymes. The activity of phospholipases A2 was reduced by more than 25% after treatment with black tea and yerba mate. The most significant inhibition of protease activity was observed after incubation with black tea (40.74%), green tea (31.48%) and yerba mate (25.93%). Infusions of black and green tea reduced hemolysis in semisolid and liquid media, and for the latter, reductions of up to 50% of hemolytic activity were observed, indicating an anti-inflammatory potential of the samples. Plasma incubations with green tea, black tea and lemon balm and subsequent addition of venom (1:10 ratio; tea:PBS, v:v) prolonged the coagulation time of citrated plasma by approximately twice compared to the positive control. All controls with pure tea had a thrombolytic character, in higher proportions than the venom control, especially chamomile (273.55% dissolution). Phenolic compounds derived from phenolic acids, flavonoids, and tannins are identified as the main agents that promote the biological effects observed in this study. This is mainly due to their anti-catalytic properties exerted on inflammatory enzymes and as chelating agents of enzymatic co-factors. The evaluated teas showed potential for nutraceutical use, thus pointing to the possibility of use as an adjuvant in the treatment of diseases linked to hemostasis.

Objective: to understand the meaning attributed by men to the experience of caring for their family member with cancer and to develop a substantive theory that represents the experience of men caring for their family member with cancer.

Abstract We investigated the Biogran on bone repair and metabolism at several time-intervals upon grafting into rat tibia artificial defects. The biomaterial was thoroughly characterized in vitro, and its dissolution behavior upon immersion was assessed in simulated body fluid (SBF) solution for 1, 3, 7, 14, and 30 days. Biogran was also assessed by in vitro hydroxyapatite formation in SBF solution, which is a marker for bioactive behavior. In vivo, distal and proximal bone defects were performed in the Wistar rat's right tibia and filled according to the experimental groups: I) negative control, no filling; II) positive control, 10 mg of autogenous bone; and III) 10 mg of Biogran. Animals were euthanized at 1, 2, 3, 4, 7, and 10 weeks. Bone neoformation was analyzed using histomorphometry (proximal defect), and local levels of bone morphogenetic protein 2 (BMP-2) were measured using the ELISA assay (distal defect). In vitro, the Biogran sample showed a fast dissolution rate within the first 7 days, parallel to the formation of the hydroxyapatite layer. In vivo, the sample was progressively resorbed at a higher rate within the first month until it became almost absent at week 10th. The sample presented similar or higher bone neoformation concerning the autogenous bone. BMP-2 levels were sustained in the Biogran group (around 200 pg/mg) and detected until the last experimental time with a significant difference compared with the controls. Results suggest Biogran is a candidate for hard tissue engineering even in highly active bone remodeling sites.

SUMMARY OBJECTIVE: The objective of the present study was to verify the indication of common mental disorder and changes in healthy lifestyle among individuals affected by coronavirus disease, as well as to evaluate if changes in healthy lifestyle are predictors of common mental disorder. METHODS: This descriptive, cross-sectional study employed an exploratory approach and quantitative methodology, using the Self-Reporting Questionnaire to assess the indication of common mental disorder and questions regarding healthy lifestyle during the pandemic. RESULTS: A total of 280 individuals affected by coronavirus disease, aged 18 years and above, participated in the study. The average indication for common mental disorder was 5.0±5.34. The average age was characterized by adults (41.24±14.03 years), with the majority being women (57.9%), White (51.4%), and those in stable relationships (55.7%). Worsening sleep quality (β==6.327; p<0.001) was the main predictor of common mental disorder, followed by female gender (β==2.814; p<0.001) and worsening dietary habits (β==2.227; p<0.012). CONCLUSION: These factors should be considered in the assessment of individuals affected by coronavirus disease to provide comprehensive care.

Abstract Objective To analyze the prevalence and factors associated with hospitalization of elderly people with COVID-19 in the State of Paraná, PR, Brazil. Methods A cross-sectional study linked to the cohort “Longitudinal Monitoring of adults and elderly people who were discharged from hospital admission due to COVID-19”, was carried out using information contained in the compulsory notification forms of the Notifiable Diseases Information System. Analyzes were carried out using relative and absolute frequencies, applying the chi-square test adopted in the logistic regression model. The study population included people aged 60 years or over and residing in the State of Paraná, who were hospitalized for COVID-19 from March 2020 to September 2021. Results A higher hospitalization prevalence was identified among elderly people with eight years of education or more. Individuals not vaccinated against COVID-19 had a greater chance of hospitalization. Males had a greater chance of admission to the Intensive Care Unit compared to females. Cardiovascular diseases, lung disease, and obesity have increased the prevalence of the severe form of the disease. Conclusion Factors such as education and non-adherence to vaccination against COVID-19 can increase the risk of hospitalization due to the disease. Elderly people of the male sex have a greater chance of hospitalization in the ICU compared to the female sex. Furthermore, not using antivirals can contribute to worsening health status.

Abstract This study aimed to identify dietary patterns and to evaluate the association between body image perception and these patterns among schoolchildren. A cross-sectional study was conducted on 385 schoolchildren (both sexes, 10-17 years old) from four public schools in Salvador, Brazil. Two non-consecutive 24-hour dietary recalls were applied, and the dietary pattern was determined by Exploratory Factor Analysis after adjustment of dietary data using the Multiple Source Method. To evaluate body image perception, the Brazilian body shape silhouette was used. The associations between body image perception and dietary patterns using the polytomous logistic regression model adjusted for covariables was assessed. Three dietary patterns were obtained: “Western standard,” unhealthy, “healthy pattern” and “typical dishes/ junk food.” After adjustment, adolescents who wished for a slimmer silhouette (2.48 [95%CI: 1.04-6.11], 3.49 [95%CI: 1.35-9.05] and 2.87 [95%CI: 1.13-7.26]) were more likely to adhere to the quintiles with the lowest consumption of the Western standard, compared to those satisfied with their body image. No associations were identified in the other two dietary patterns. Adolescents dissatisfied with their bodies tend to adhere less to unhealthy dietary patterns.

Resumo Este estudo objetivou identificar padrões alimentares e avaliar a associação entre percepção da imagem corporal e esses padrões em escolares. Um estudo transversal foi conduzido em 385 escolares (ambos os sexos, 10-17 anos de idade) de 4 escolas públicas de Salvador, Brasil. Dois recordatórios alimentares de 24h não consecutivos foram aplicados e o padrão alimentar foi determinado por Análise Fatorial Exploratória, após ajuste dos dados dietéticos pelo Multiple Source Method. Para avaliar percepção da imagem corporal, nós usamos uma escala brasileira de silhuetas. Avaliamos as associações entre percepção da imagem corporal e padrões alimentares usando o modelo de regressão logística politômica ajustado para covariáveis. Três padrões alimentares foram obtidos: “padrão ocidental”, “padrão saudável” e “comidas típicas/junk food”. Após ajuste, adolescentes que desejavam uma silhueta menor (2,48 [IC95%: 1,04-6,11], 3,49 [IC95%: 1,35-9,05] e 2,87 [IC95%: 1,13-7,26]) tinham mais chances de aderir aos quintis de menor consumo do padrão ocidental, comparados àqueles satisfeitos com sua imagem corporal. Nenhuma associação foi identificada nos outros dois padrões alimentares. Adolescentes insatisfeitos com seus corpos tendem a aderir menos a padrões alimentares não saudáveis.

ABSTRACT BACKGROUND: The identification and understanding of dietary factors and other characteristics that influence gestational weight gain can contribute to the formulation of strategies to promote healthy eating habits before and during pregnancy. OBJECTIVE: To investigate the association between dietary patterns, sociodemographic and obstetric characteristics, and health-related behaviors in pregnant women. DESIGN AND SETTING: A cross-sectional study was conducted on women undergoing prenatal care in the Unified Health System of Colombo, Paraná, Brazil, from February 2018 to September 2019. METHOD: A weekly food frequency questionnaire was administered, and dietary patterns were identified through factor analysis. Median regression models were constructed to identify the associations between dietary pattern scores and variables. RESULTS: Complete data were obtained from 495 pregnant women. Three dietary patterns were identified: 1) “healthy,” with higher factor loadings for the weekly consumption of raw vegetables, cooked vegetables, and fresh fruits; 2) “Western,” including soft drinks or artificial juice, candies, milk, and dairy products, and processed cold meat; and 3) “traditional,” beans and meat. Pregnant women aged 30 years or older (coefficient [Coef.] 0.86, 95% confidence interval [CI] 0.38–1.33) with moderate/intense physical activity (Coef. 0.32, 95% CI 0.02–0.62) had higher adherence to the “healthy” pattern. Adolescents and smokers adhered more to the “traditional” pattern (Coef. 0.17, 95% CI 0.01–0.33). CONCLUSION: Age, smoking status, and physical activity were associated with dietary patterns in pregnant women.

Abstract Objective Identify the profile of births of pregnancies of women with internet access who were infected with SARS-CoV-2 and their outcomes. Methods Cross-sectional study integrated into a prospective cohort, with collection between August 2021 and February 2022, based on the responses of 304 women who had pregnancies and/or deliveries during the pandemic period. Results Of the total, 25.7% of the interviewees had COVID-19, with a predominance of diagnoses in the third quarter. Complaints of anosmia, fatigue and headache prevailed as related to the infection. The variables using the Unified Health System for care (p = 0.084); gestational diabetes (p = 0.141); low birth weight (p = 0.117); need for admission to a neonatal unit (p = 0.120) were included in the regression model because they had p values lower than 0.20. The variable referring to the type of delivery (p=1.000) was inserted in the model because it is a variable of interest and with a description of relevance in the literature. Prematurity was the only variable that was statistically associated with SARS-CoV-2 infection during pregnancy (p = 0.008) in the bivariate analysis, explaining the outcome of infection during pregnancy (<0.001), confirmed in the Poisson Robust Regression model. Conclusion There was a high prevalence of COVID-19 in the sample, with varying symptoms and a predominance of operative deliveries. However, SARS-CoV-2 infection only explained the higher occurrence of premature births.

Abstract Objective To describe acute kidney injury prevalence in young adults diagnosed with COVID-19 admitted to the Intensive Care Unit. Methods This is a retrospective, quantitative and analytical study. The sample consisted of young adults (20 to 40 years old) admitted to Intensive Care Units, diagnosed with SARS-CoV-2 infection between March and December 2020. Data were obtained through electronic medical records, and kidney injury acute was defined by the creatinine value, according to the Kidney Disease Improving Global Outcomes guidelines criteria. Statistical significance was p≤0.05. Results A total of 58 young adults were hospitalized, 63.8% of whom were male. Hypertension was present in 39.6%, obesity in 18.9%, and diabetes mellitus in 8.6%. Acute kidney injury was identified in 55.1%, with stage 3 predominating in 43.1% of them. In these patients, the use of mechanical ventilation and vasoactive drugs was significant in 92% as well as respiratory organ dysfunction (80%), followed by renal organ dysfunction (76%). Risk factors such as kidney transplantation or chronic kidney disease and obesity increased by 12.3 and 9.0 times, respectively, the chances of developing acute kidney injury. Conclusion This study demonstrated a high kidney injury prevalence in young adults and its association with previous comorbidities. Obesity, kidney transplantation and chronic kidney disease increased the chance of young adults to develop acute kidney injury, resulting in outcomes in favor of morbidity and mortality.

ABSTRACT Purpose Longitudinally verify the influence of auditory tonal thresholds obtained with transcutaneous and percutaneous bone-anchored hearing aids on speech perception in individuals with external and/or middle ear malformation and chronic otitis media. Methods Observational, retrospective, longitudinal follow-up study of 30 unilateral users of the transcutaneous and percutaneous Baha® system for the collection of secondary data on pure tone thresholds obtained through free field audiometry and sentence recognition threshold in silence and noise in conditions: without the prosthesis; at the time of activation; in the first month of use (post 1); and in the third month (post 2). Results There was a significant difference between pure tone thresholds obtained at frequencies of 3 and 4kHz with better results for the percutaneous technique at all evaluation moments. For both systems, better performance was observed in sentence recognition in silence and in noise, with a significant difference in activation (p<0.001), but it remained stable during the other evaluation moments. The percutaneous system showed better benefit in recognizing sentences in noise only on activation (p=0.036), when compared to the transcutaneous system. Conclusion The percutaneous system provided better audibility for high frequencies; however, such audibility did not influence sentence recognition in the silent situation for both systems. For the noise situation, better responses were observed in the percutaneous system, however, the difference was not maintained over time.

RESUMO Objetivo Verificar longitudinalmente a influência dos limiares tonais auditivos obtidos com as próteses auditivas ancoradas no osso transcutâneas e percutâneas na percepção da fala em indivíduos com malformação de orelha externa e/ou média e Otite Média Crônica. Método Estudo observacional, retrospectivo, de seguimento longitudinal de 30 indivíduos usuários unilaterais de sistema Baha® transcutâneo e percutâneo, para coleta de dados secundários dos limiares tonais obtidos por meio da audiometria em campo livre e do limiar de reconhecimento de sentenças no silêncio e no ruído nas condições: sem a prótese; no momento de ativação; no primeiro mês de uso (pós 1); e no terceiro mês (pós 2). Resultados Houve diferença significante entre os limiares tonais obtidos nas frequências de 3 e 4kHz, com melhores resultados para o percutâneo em todos os momentos de avaliação. Para os dois sistemas, observou-se melhor desempenho no reconhecimento de sentenças no silêncio e ruído, com diferença significante na ativação (p<0,001), porém manteve-se estável nos demais momentos de avaliação. O sistema percutâneo mostrou melhor benefício no reconhecimento de sentenças no ruído apenas na ativação (p=0,036), quando comparado ao transcutâneo. Conclusão O sistema percutâneo possibilitou melhor audibilidade para as frequências altas; contudo, tal audibilidade não influenciou no reconhecimento de sentenças na situação de silêncio para ambos os sistemas. Para a situação de ruído, melhores respostas foram observadas no sistema percutâneo; porém, a diferença não se manteve no decorrer do tempo.
