Abstract This study aimed to estimate the prevalence and extent of bleeding on probing and calculus in 12-year-old schoolchildren of Quito, Ecuador, and evaluate the associated factors. We conducted an epidemiological survey with a representative sample of 1,100 12-year-old schoolchildren from public schools in the urban area of Quito, Ecuador. We assessed the periodontal health using the Community Periodontal Index (CPI). The prevalence and extent of the periodontal condition was based on the presence of at least one site with bleeding on probing (BOP), and the presence of dental calculus was also evaluated. We used univariate and multiple multilevel Poisson regression analyses to verify the association between the independent variables and the number of sextants with BOP and calculus. The prevalence of BOP and calculus was 92% and 69.9%, respectively. The adjusted mean of the affected sextants was 4.3 and 2.2 for BOP and calculus, respectively. The mother’s schooling and malocclusion were associated with the number of sextants with bleeding. The mother’s schooling and dental caries experience were associated with calculus. Gingival bleeding and the presence of dental calculus are highly prevalent in 12-year-old schoolchildren from Quito. Gingival bleeding is associated with maternal education and malocclusion, and dental calculus is associated with maternal education and dental caries.

ABSTRACT The use of echocardiography by physicians who are not echocardiographers has become common throughout the world across highly diverse settings where the care of acutely ill patients is provided. Echocardiographic evaluation performed in a point-of-care manner can provide relevant information regarding the mechanism of causes of shock, for example, increasing the rates of correct diagnosis and allowing for faster informed decision-making than through evaluation methods. Considering that the accurate diagnosis of life-threatening situations is essential for professionals working with acutely ill patients, several international associations recommend that physicians responsible for critically ill patients acquire and develop the ability to perform bedside ultrasound examinations, including echocardiographic examinations. However, there is no consensus in the literature regarding which specific applications should be included in the list of skills for nonechocardiographer physicians. Taking into account the multiplicity of applications of echocardiography in different scenarios related to acutely ill patients; the differences in the published protocols, with regard to both the teaching methodology and competence verification; and the heterogeneity of training among highly diverse specialties responsible for their care at different levels, this consensus document aimed to reflect the position of representatives of related Brazilian medical societies on the subject and may thus serve as a starting point both for standardization among different specialties and for the transmission of knowledge and verification of the corresponding competencies.

RESUMO O emprego da ecocardiografia por médicos não ecocardiografistas tem se tornado comum em todo o mundo nos mais diversos ambientes em que se dá o cuidado do paciente agudamente doente. A avaliação ecocardiográfica realizada de forma point-of-care pode fornecer informações pertinentes em relação ao mecanismo das causas de choque, por exemplo, incrementando as taxas de diagnóstico correto e possibilitando a tomada de decisão fundamentada de forma mais rápida do que por meio dos métodos tradicionais de avaliação. Considerando que o diagnóstico preciso de situações ameaçadoras à vida é indispensável a profissionais atuando junto a pacientes agudamente enfermos, diversas entidades associativas internacionais recomendam que médicos responsáveis por pacientes gravemente doentes devam adquirir e desenvolver a habilidade para realizar exames ultrassonográficos à beira do leito, inclusive ecocardiográficos. Entretanto, não há consenso na literatura acerca de quais aplicações específicas devam compor o rol de habilidades do médico não ecocardiografista. Levando-se em consideração a multiplicidade de aplicações da ecocardiografia em diversos cenários relativos ao paciente agudamente enfermo; as diferenças nos protocolos publicados, tanto no que diz respeito à metodologia de ensino como de verificação de competências, bem como a heterogeneidade da formação entre as mais diversas especialidades responsáveis pelo seu cuidado em diferentes níveis, este documento de consenso teve o objetivo de refletir o posicionamento de representantes de sociedades médicas brasileiras afins acerca do tema, podendo, assim, servir de ponto de partida para a uniformização entre diferentes especialidades, bem como para a transmissão de conhecimento e a verificação das competências correspondentes.

Abstract The establishment of epigenetic marks during the reprogramming window is susceptible to environmental influences, and stimuli during this critical stage can cause altered DNA methylation in offspring. In a previous study, we found that low levels of sulphur and cobalt (low S/Co) in the diet offered to oocyte donors altered the DNA methylome of bovine embryos. However, due to the extensive epigenetic reprogramming that occurs during embryogenesis, we hypothesized that the different methylation regions (DMRs) identified in the blastocysts may not maintain in adulthood. Here, we aimed to characterize DMRs previously identified in embryos, in the blood and sperm of adult progenies of two groups of heifers (low S/Co and control). We used six bulls and characterized the DNA methylation levels of KDM2A, KDM5A, KMT2D, and DOT1L genes. Our results showed that all DMRs analysed in both groups and tissues were hypermethylated unlike that noticed in the embryonic methylome profiles. These results suggest that embryo DMRs were reprogrammed during the final stages of de novo methylation during embryogenesis or later in development. Therefore, due to the highly dynamic epigenetic state during early embryonic development, we suggest that is essential to validate the DMRs found in embryos in adult individuals.

ABSTRACT Ensuring prompt and effective water quality monitoring is increasingly important. Remote sensing has been shown to be an effective tool for simplifying and speeding up this process. The aim of this study is to develop an empirical model to map the spatial and temporal dynamics of turbidity in Mirim Lagoon, located in southern Brazil. To achieve this, Sentinel-2A/B MSI sensor data were combined with turbidity data collected in situ. The model was applied to monthly images (with cloud cover ≤ 20%) in 2019 and 2020 using the Google Earth Engine (GEE) platform. Mean turbidity values in the lagoon did not vary significantly, remaining between 30 and 75 NTU overall. However, there were differences in turbidity levels between the northern and southern regions of the lagoon in some months of the investigated years. By applying this methodology and analyzing the results, we were able to better understand the behavior of turbidity throughout the lagoon and gain insights into the quality of this important freshwater source.

RESUMO Tem se tornado cada vez mais necessário garantir agilidade e eficácia no monitoramento da qualidade da água. Nesse sentido, o sensoriamento remoto tem se mostrado uma ferramenta eficaz, capaz de tornar esse processo mais rápido e simples. O objetivo do presente estudo é gerar um modelo empírico para mapear espacial e temporalmente a dinâmica da turbidez na Lagoa Mirim, sul do Brasil. Os dados do sensor MSI Sentinel-2A/B foram usados em combinação com os dados de turbidez coletados in situ. Os mapeamentos espaciais e temporais foram realizados na plataforma Google Earth Engine (GEE) aplicando o modelo em imagens mensais (cobertura de nuvens ≤ 20%), em 2019 e 2020. Os valores médios de turbidez observados na lagoa não apresentaram variações significativas; no geral, eles permaneceram entre 30 NTU e 75 NTU. Houve diferença nos níveis de turbidez entre as regiões Norte e Sul da lagoa em alguns meses dos anos investigados. A metodologia aqui aplicada e os resultados observados permitiram analisar o comportamento da turbidez em toda a extensão da Lagoa Mirim e conhecer melhor a qualidade da água nesta importante fonte de água doce.

Abstract The purpose of this study was to compare the outcomes of a modified gingival graft technique, in which the released flap is positioned and sutured over the graft, with the conventional free gingival graft (FGG) procedure, when both are used for gingival augmentation. A 12-month, multicenter parallel randomized controlled trial was conducted. Subjects with buccal RT2 gingival recessions and keratinized tissue width (KTW) < 2 mm in at least one mandibular incisor were randomized to control group (n = 20; conventional FGG) or test group (n = 20; modified FGG; flap sutured over FGG using sling sutures). The primary outcome (KTW) was measured at baseline and after 3, 6 and 12 months, as was keratinized tissue thickness (KTT). Postoperative pain (POP) and analgesic intake were also recorded. Both techniques promoted a significant increase in KTW and KTT when compared to baseline (p < 0.05) with no significant differences between groups (KTW change of 6.1±1.5 mm and 5.4±1.6 mm, for control and test, respectively; p=0.16). However, test group patients reported less POP after 7 days and used less analgesic medication than control group patients (p < 0.05). We concluded that the modified FGG was comparable to conventional FGG in augmenting keratinized tissue width and thickness at mandibular incisors, but resulted in less patient morbidity.

Abstract Background Cardiovascular complications of COVID-19 are important aspects of the disease’s pathogenesis and prognosis. Evidence on the prognostic role of troponin and myocardial injury in Latin American hospitalized COVID-19 patients is still scarce. Objectives To evaluate myocardial injury as independent predictor of in-hospital mortality and invasive mechanical ventilation support in hospitalized patients, from the Brazilian COVID-19 Registry. Methods This cohort study is a substudy of the Brazilian COVID-19 Registry, conducted in 31 Brazilian hospitals of 17 cities, March-September 2020. Primary outcomes included in-hospital mortality and invasive mechanical ventilation support. Models for the primary outcomes were estimated by Poisson regression with robust variance, with statistical significance of p<0.05. Results Of 2,925 patients (median age of 60 years [48-71], 57.1% men), 27.3% presented myocardial injury. The proportion of patients with comorbidities was higher among patients with cardiac injury (median 2 [1-2] vs. 1 [0-2]). Patients with myocardial injury had higher median levels of brain natriuretic peptide, lactate dehydrogenase, creatine phosphokinase, N-terminal pro-brain natriuretic peptide, and C-reactive protein than patients without myocardial injury. As independent predictors, C-reactive protein and platelet counts were related to the risk of death, and neutrophils and platelet counts were related to the risk of invasive mechanical ventilation support. Patients with high troponin levels presented a higher risk of death (RR 2.03, 95% CI 1.60-2.58) and invasive mechanical ventilation support (RR 1.87, 95% CI 1.57-2.23), when compared to those with normal troponin levels. Conclusion Cardiac injury was an independent predictor of in-hospital mortality and the need for invasive mechanical ventilation support in hospitalized COVID-19 patients.

Resumo Fundamento As complicações cardiovasculares da COVID-19 são aspectos importantes da patogênese e do prognóstico da doença. Evidências do papel prognóstico da troponina e da lesão miocárdica em pacientes hospitalizados com COVID-19 na América Latina são ainda escassos. Objetivos Avaliar a lesão miocárdica como preditor independente de mortalidade hospitalar e suporte ventilatório mecânico em pacientes hospitalizados, do registro brasileiro de COVID-19. Métodos Este estudo coorte é um subestudo do registro brasileiro de COVID-19, conduzido em 31 hospitais brasileiros de 17 cidades, de março a setembro de 2020. Os desfechos primários incluíram mortalidade hospitalar e suporte ventilatório mecânico invasivo. Os modelos para os desfechos primários foram estimados por regressão de Poisson com variância robusta, com significância estatística de p<0,05. Resultados Dos 2925 pacientes [idade mediana de 60 anos (48-71), 57,1%], 27,3% apresentaram lesão miocárdica. A proporção de pacientes com comorbidades foi maior nos pacientes com lesão miocárdica [mediana 2 (1-2) vs. 1 (0-20)]. Os pacientes com lesão miocárdica apresentaram maiores valores medianos de peptídeo natriurético cerebral, lactato desidrogenase, creatina fosfoquinase, N-terminal do pró-peptídeo natriurético tipo B e proteína C reativa em comparação a pacientes sem lesão miocárdica. Como fatores independentes, proteína C reativa e contagem de plaquetas foram relacionados com o risco de morte, e neutrófilos e contagem de plaquetas foram relacionados ao risco de suporte ventilatório mecânico invasivo. Os pacientes com níveis elevados de troponina apresentaram um maior risco de morte (RR 2,03, IC95% 1,60-2,58) e suporte ventilatório mecânico (RR 1,87;IC95% 1,57-2,23), em comparação àqueles com níveis de troponina normais. Conclusão Lesão cardíaca foi um preditor independente de mortalidade hospitalar e necessidade de suporte ventilatório mecânico em pacientes hospitalizados com COVID-19.

Abstract Accumulated evidence has shown that the oral cavity may be an important reservoir for SARS-CoV-2. Some authors have suggested that the use of mouthrinses could reduce SARS-CoV-2 viral load in the saliva. Thus, the aim of this review was to synthesize evidence about the efficacy of mouthrinses in reducing the salivary viral load of SARS-CoV-2. 2. Nine randomized controlled trials (RCTs) have investigated the efficacy of different mouthrinses in reducing salivary SARS-CoV-2 loads. Various active ingredients have been tested in these trials: 0.5%,1% and 2% povidone-iodine, 0.2% and 0.12% chlorhexidine (CHX), 0.075% cetylpyridinium chloride (CPC), 0.075% CPC with Zinc lactate, 1% and 1.5% hydrogen peroxide (HP), 1.5% HP + 0.12% CHX and ß-cyclodextrin and citrox. The studies reported an intra-group reduction in the salivary levels of the virus, when compared with the baseline. However, the majority of these trials failed to demonstrate a significant inter-group difference between active groups and the control group relative to the decrease in salivary SARS-CoV-2 loads. Although promising, these results should be confirmed by larger trials.

Abstract The phenolic compound content, the antioxidant and α-amylase inhibition potentials of different extracts of the Plectranthus amboinicus, P. barbatus and P. ornatus were evaluated. We also evaluated the influence of plant growth and harvest time on the chemical composition of the essential oil (EO) of P. amboinicus, its antioxidant and anti-Candida activities and the α-amylase and lipoxygenase inhibitions. The turbo-extract of P. barbatus showed the greatest phenolic compound content and antioxidant activity. No α-amylase inhibition activity was observed in the analyzed extracts, but the turbo-extraction and refluxing extracts possessed high antioxidant activities. Protected cultivation and morning harvest conditions gave the best antioxidant activities, which was associated to the highest carvacrol content. P. amboinicus EO antioxidant activity could contribute to the reduction of oxidative stress in diabetes. Causal Candida strains of diabetic foot ulcers showed sensitivity to P. amboinicus EO. C. albicans and C. dubliniensis were the most sensitive of the selected Candida strains. Turbo-extracts or refluxing of the three species extracts and the EO of P. amboinicus should be considered as a potential candidate for the management the complications of type 2 diabetes.

ABSTRACT Introduction: Since the beginning, plastic surgery has improved self-esteem and acceptance in a society that idealizes the cult of the body. The pressure of consumption and the ease of undergoing plastic surgery becomes an obsession in these patients’ lives. Method: Female patients who underwent psychological evaluation and follow-up throughout the surgical and plastic surgery procedure, aged between 19 and 57, answered the Sociocultural Attitudes Questionnaire concerning appearance and the Body Dysmorphophobia Symptom Scale. Results: Of the 38 patients evaluated, 17 have the media as an influence concerning their body image and have symptoms of Body Dysmorphic Disorder (BDD), 13 patients have the media as an influence on their body image, but they do not have BDD symptoms, and in eight patients the media does not influence their body image, and they do not have BDD symptoms. Conclusion: The importance of a multidisciplinary team, with a psychologist, is highlighted to evaluate and monitor the patient throughout the surgical process, as the early diagnosis of BDD will avoid dissatisfaction with the result of the plastic surgery and, mainly, future court lawsuits.

RESUMO Introdução: Desde os primórdios, a cirurgia plástica melhora a autoestima e a aceitação em uma sociedade que idealiza o culto ao corpo. A pressão do consumo e a facilidade de se submeter a um procedimento de cirurgia plástica acabam tornando-se obsessão na vida desses pacientes. Método: Pacientes do sexo feminino que passaram por avaliação e acompanhamento psicológico em todo o processo cirúrgico, e procedimento de cirurgia plástica, com a idade entre 19 e 57 anos, responderam ao questionário de Atitudes Socioculturais em relação a aparência e a Escala de Sintomas de Dismorfobia Corporal - Body Dysmorphic Scale. Resultados: Dos 38 pacientes avaliados, 17 têm a mídia como influência em relação a sua imagem corporal e apresentam sintomas do Transtorno Dismórfico Corporal (TDC), 13 pacientes têm a mídia como influência em relação a sua imagem corporal, mas não apresentam sintomas do TDC, e em oito pacientes a mídia não influencia em relação a sua imagem corporal e não apresentam sintomas do TDC. Conclusão: Destaca-se a importância de uma equipe multidisciplinar, com a presença de um psicólogo, para avaliar e acompanhar o paciente em todo processo cirúrgico, pois o diagnóstico precoce do TDC evitará uma insatisfação com o resultado da cirurgia plástica e, principalmente, futuros processos judiciais.

Abstract The germination potential must be considered in the selection of passion fruit genotypes, since vigorous seeds originate seedlings with a higher growth rate, resulting in superior plants with high agronomic performance. This study proposes to estimate genetic parameters and selection gain for seed traits of full-sib families (FSF) of passion fruit under recurrent selection for resistance to the cowpea aphid-borne mosaic virus (CABMV). Physical and physiological seed traits of 86 FSF were evaluated; genetic parameters, genotypic correlations between traits and genetic gains were estimated using four selection indices. There were significant differences and genetic variability between families and positive genetic correlations between variables. The best distribution of genetic gains was obtained by the Mulamba and Mock index, using the heritability coefficient and arbitrary weights. This index selected the best 26 families in terms of seed characteristics to compose the second cycle of recurrent selection for resistance to CABMV.

Abstract The induction of polyploidy in Eucalyptus can lead to higher-yielding and more adapted clones, with better wood quality. After artificial polyploidization, it is necessary to certify the effectiveness of the process through cytogenetic analyses and anatomical trait evaluations. Thus, the aim of this study was to certify the chromosome duplication in artificially polyploidized clones of Eucalyptus grandis × Eucalyptus urophylla using cytogenetic analysis, flow cytometry, and leaf anatomy measurements. Chromosomal counts and DNA content estimation allowed the identification of artificially polyploidized clones and mixoploids. Polyploid clones had larger stomata diameter than diploids. The increase in stomata size was accompanied by lower stomatal density in most polyploid clones. The typical gigas effect of polyploidized plants was demonstrated by the expressive increase in leaf area in polyploid individuals compared to diploids. Our findings indicate that the use of polyploidy in Eucalyptus breeding is promising, allowing the discrimination of diploid, tetraploid, and mixoploid plants.
