Abstract Flow accelerated corrosion (FAC) is a steel degradation that occurs in heat recovery steam generators in the power industry. The mechanism of this corrosion comprises an electrochemical dissolution of the semi-protective magnetite layer (Fe3O4) that is formed within the pipes employed in the boilers. The FAC is influenced by different factors such as fluid velocity, pH and dissolved oxygen concentration. In this context, Rotating Cage tests were used to evaluate the influence of pH and dissolved oxygen content on FAC of A210, P11 and P22 steels. General corrosion was lower for P11 and P22 steels, an effect consistent with the presence of chromium in their compositions. General corrosion was most critical at pH 8.5. The corrosion intensity decreased for the three steels when the dissolved oxygen concentration increased, at 2 m/s. This behavior is coherent considering the most effective precipitation of Fe2O3 inside the pores of the Fe3O4 layer in a more oxidizing environment. For 3 m/s, the corrosion intensity increased for both materials when oxygen increased, showing the shear stress effect. These behaviors were more significant at pH 8.5. About pitting corrosion, the analyzes show localized attack in the majority of coupons, however with very low number of pits.

Resumo Introdução A mordida aberta anterior é um dos tipos de má-oclusão mais frequentes em pré-escolares, sendo considerada um dos problemas oclusais mais difíceis de tratar, principalmente por sua etiologia multifatorial e sua íntima relação com hábitos bucais deletérios. Objetivo Identificar a prevalência de mordida aberta anterior nos pré-escolares de Salvador-BA, bem como fatores potencialmente associados à mesma. Material e método Trata-se de um estudo de corte transversal em 1.577 crianças em idade pré-escolar (36 a 71 meses), que frequentavam creches públicas municipais de Salvador-BA. Resultado A média de idade das crianças foi aproximadamente 54 meses. A maioria pertencia ao sexo masculino (50,29%). A população de estudo foi predominantemente composta por negros e pardos (92,02%). A prevalência de má-oclusão foi de 40,46% e, destes, 14,02% possuíam mordida aberta. Com relação à escolaridade, a maior parte das mães (55,86%) e dos pais (50,08%) foi igual ou superior ao Ensino Fundamental II Completo. A sucção digital foi comum em 6,73% das crianças e 10,39% faziam sucção de chupeta. Foram identificados, como fatores de proteção à mordida aberta, a escolaridade do pai maior ou igual ao Ensino Fundamental II completo (RP= 0,62 IC= 0,41-0,95) e a onicofagia (RP= 0,34 IC= 0,21-0,56). Como fatores de risco, identificaram-se o uso de chupeta (RP= 17,98 IC= 10,91-29,62) e a sucção digital (RP= 11,04 IC= 6,0-20,32). Conclusão Medidas educativas direcionadas aos pais e responsáveis se fazem essenciais para a prevenção do desenvolvimento de hábitos deletérios nos pré-escolares. Outros estudos são necessários a fim de aprofundar o entendimento sobre os fatores de proteção identificados neste estudo.

Abstract Introduction The previous open bite is one of the most frequent types of malocclusions in preschoolers, being considered one of the most difficult occlusal problems to treat, mainly due to its multifactorial etiology and its intimate relationship with deleterious oral habits. Objective Identify the prevalence of anterior open bite in preschoolers in Salvador-BA as well as factors potentially associated with it. Material and method This is a cross-sectional study of 1577 preschool children (36 to 71 months) who attended municipal public daycare centers in Salvador-BA. Result The children's average age was approximately 54 months. Most were male (50.29%). The study population was predominantly composed of blacks and browns (92.02%). The prevalence of malocclusion was 40.46%, of which 14.02% of these children had an open bite. Regarding schooling, most mothers (55.86%) and fathers (50.08%) were equal to or higher than complete primary school. The digital sucking was common in 6.73% of the children and 10.39% used pacifiers. As protective factors for open bite were found the father's education level ≥ 1st complete degree (PR = 0.62 CI = 0.41-0.95) and nail-biting (PR = 0.34 CI = 0.21-0.56). As risk factors were found the use of pacifiers (PR = 17.98 CI = 10.91-29.62) and digital suction (PR = 11.04 CI = 6.0-20.32). Conclusion Educational measures aimed at parents and guardians are essential to prevent the development of harmful habits in preschoolers. Other studies are needed for in order to deepen the understanding of the identified protection factors in this study.

Abstract Some conditions consolidated as risk factors for oropharyngeal dysphagia have already been identified in other diseases, such as neurological. Studies on cardiovascular diseases concentrate in individuals in the postoperative period; thus, it is unknown if these same factors occur in individuals hospitalized for clinical or surgical treatment of these diseases. Objective to correlate predictive risk factors for oropharyngeal dysphagia in individuals with cardiovascular disease admitted at a reference cardiology hospital. Methodology This is a retrospective clinical study. Medical records of 175 individuals hospitalized for clinical and/or surgical treatment at a reference cardiology hospital from January to June 2017, attendants of the Speech-Language Pathology and Nutrition team, were analyzed. Of these, 100 records were included in the study: 41 females and 59 males (mean age 67.56 years). Deaths and individuals from 0 to 18 years were excluded. Stroke, malnutrition, age and prolonged orotracheal intubation were considered predictive risk factors for oropharyngeal dysphagia. Mann-Whitney test and Fisher's test were used for statistical analysis. Results Stroke (OR=2.93 p=0.02), malnutrition (OR=2.89 p=0.02) and prolonged orotracheal intubation (OR=3.94 p=0.02) were statistically significant predictors for oropharyngeal dysphagia within this population. Age below 80 years was not significant (p=0.06), but within octogenarians, significance was found (p=0.033). Conclusion Stroke, malnutrition, prolonged orotracheal intubation and age > 80 years are predictive risk factors for oropharyngeal dysphagia in adult population with cardiovascular diseases.

BACKGROUND Infection with Zika virus (ZIKV) manifests in a broad spectrum of disease ranging from mild illness to severe neurological complications and little is known about Zika immunopathogenesis. OBJECTIVES To define the immunologic biomarkers that correlate with acute ZIKV infection. METHODS We characterized the levels of circulating cytokines, chemokines, and growth factors in 54 infected patients of both genders at five different time points after symptom onset using microbeads multiplex immunoassay; comparison to 100 age-matched controls was performed for statistical analysis and data mining. FINDINGS ZIKV-infected patients present a striking systemic inflammatory response with high levels of pro-inflammatory mediators. Despite the strong inflammatory pattern, IL-1Ra and IL-4 are also induced during the acute infection. Interestingly, the inflammatory cytokines IL-1β, IL-13, IL-17, TNF-α, and IFN-γ; chemokines CXCL8, CCL2, CCL5; and the growth factor G-CSF, displayed a bimodal distribution accompanying viremia. While this is the first manuscript to document bimodal distributions of viremia in ZIKV infection, this has been documented in other viral infections, with a primary viremia peak during mild systemic disease and a secondary peak associated with distribution of the virus to organs and tissues. MAIN CONCLUSIONS Biomarker network analysis demonstrated distinct dynamics in concurrence with the bimodal viremia profiles at different time points during ZIKV infection. Such a robust cytokine and chemokine response has been associated with blood-brain barrier permeability and neuroinvasiveness in other flaviviral infections. High-dimensional data analysis further identified CXCL10, a chemokine involved in foetal neuron apoptosis and Guillain-Barré syndrome, as the most promising biomarker of acute ZIKV infection for potential clinical application.

ABSTRACT This study aimed to estimate heritability, genetic, and residual correlations between reproductive traits such as age at first calving, calving interval, dry period, and first service period and linear type traits measured in Holstein cows born between the years 1990 and 2008 in Brazil. The (co)variance components were estimated by restricted maximum likelihood, using the MTDFREML software. The heritability for reproductive traits and linear-type traits ranged from 0.02 to 0.03 and from 0.07 to 0.40, respectively. Estimates of genetic correlations between reproductive and linear-type traits ranged from -0.23 (top line) to 0.28 (angularity) to age at first calving, from -0.54 (final score) to 0.34 (foot angle) to calving interval, from -0.23 (angularity) to 0.56 (stature) to dry period, and from -0.52 (final score) to 0.36 (height udder) to first service period. Direct selection for any of the reproductive traits implies low genetic gains by virtue of their low heritabilities. Among the linear-type traits, the final score, chest width, top line, angularity, teat length, udder attachment, rear teat placement were highlighted as good auxiliary traits to improve reproductive efficiency of Holstein cows in Brazil. The simultaneous selection for reproductive and linear-type traits can lead a higher genetic progress in the reproductive traits.

RESUMO Objetivo Este estudo tem o objetivo de identificar as evidências de validade baseadas no conteúdo e nos processos de resposta de um instrumento de Rastreamento para disfagia orofaríngea no Acidente Vascular Encefálico (RADAVE). Método Os critérios para elaborar os itens do instrumento foram baseados na revisão de literatura. Um grupo de juízes com 19 profissionais distintos e da área da saúde avaliaram a relevância e representatividade das questões e o resultado foi analisado por meio do índice de validade de conteúdo (IVC). Para evidência de validade baseada nos processos de resposta, 23 profissionais da saúde aplicaram o instrumento e analisaram as questões por meio de escala estruturada e entrevista cognitiva. Resultados O RADAVE foi estruturado para ser aplicado em duas etapas. A primeira versão foi constituída por 18 questões na etapa I e 11 questões na etapa II. Oito questões da etapa I e quatro questões da etapa II não atingiram o IVC mínimo, sendo realizadas reformulações pelos autores. A entrevista cognitiva demonstrou a necessidade de novos ajustes que resultaram na versão final com 12 questões na Etapa I e seis questões na Etapa II. Conclusão Foi possível desenvolver um instrumento de rastreamento para a disfagia no Acidente Vascular Encefálico com adequadas evidências de validade baseadas no conteúdo e nos processos de resposta. As duas evidências de validade obtidas até o momento permitiram ajustar o instrumento em relação ao seu constructo. Os próximos estudos irão analisar as demais evidências de validade e as medidas de acurácia.

ABSTRACT Purpose The aim of the present study was to identify the evidence of validity based on the content and response process of the Rastreamento de Disfagia Orofaríngea no Acidente Vascular Encefálico (RADAVE; “Screening Tool for Oropharyngeal Dysphagia in Stroke”). Methods The criteria used to elaborate the questions were based on a literature review. A group of judges consisting of 19 different health professionals evaluated the relevance and representativeness of the questions, and the results were analyzed using the Content Validity Index. In order to evidence validity based on the response processes, 23 health professionals administered the screening tool and analyzed the questions using a structured scale and cognitive interview. Results The RADAVE structured to be applied in two stages. The first version consisted of 18 questions in stage I and 11 questions in stage II. Eight questions in stage I and four in stage II did not reach the minimum Content Validity Index, requiring reformulation by the authors. The cognitive interview demonstrated some misconceptions. New adjustments were made and the final version was produced with 12 questions in stage I and six questions in stage II. Conclusion It was possible to develop a screening tool for dysphagia in stroke with adequate evidence of validity based on content and response processes. Both validity evidences obtained so far allowed to adjust the screening tool in relation to its construct. The next studies will analyze the other evidences of validity and the measures of accuracy.

RESUMO O objetivo deste estudo foi identificar e analisar, por meio de levantamento bibliográfico, a atuação fonoaudiológica em Unidades de Terapia Intensiva Neonatal (UTINs) em casos de cardiopatia congênita. Como fonte de dados foram utilizadas as seguintes plataformas: Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Medical Literature Analysis and Retrieval Sistem on-line (MEDLINE), Scielo e o serviço de pesquisa da National Library of Medicine nas bases de dados Pubmed, sistema de procura do Google Acadêmico (HTTP//scholar.google.com.br). Foram pesquisados trinta e dois trabalhos, sendo a atuação fonoaudiológica em UTINs descrita em vinte e oito deles, os quais apresentam como procedimentos avaliação e estimulação do sistema sensório-motor-oral, com uso de técnicas de sucção não-nutritiva e nutritiva, além de triagem auditiva. Porém, as características dos neonatos com cardiopatia congênita e a inserção do fonoaudiólogo em UTIN cardíaca não são citadas, pouco se caracterizando os objetivos e a prática desse profissional. Apenas uma publicação obedeceu aos critérios de inclusão do presente estudo. Trata-se de um trabalho que descreve a transição da alimentação enteral direta para o seio materno em recém-nascidos pré-termo cardiopatas, com idade corrigida, em um centro de terapia intensiva neonatal. Foi possível constatar então a escassez de trabalhos publicados sobre intervenção fonoaudiológica com RN cardiopatas, o que indica a necessidade de novos estudos sobre o tema, já que a atenção a esses pacientes deve ser diferenciada, visto que apresentam particularidades que podem comprometer o desempenho na alimentação.

ABSTRACT The purpose of this study is to identify and analyze, through bibliographical survey, the use of speech therapy care in Neonatal Intensive Care Unit (NICU) in cases of newborns with congenital heart disease. The source data is from Latin American and Caribbean Health Sciences (LILACS), Medical Literature Analysis and Retrieval System Online (MEDLINE), SciELO and the search engine of the National Library of Medicine in the databases PubMed, also the Google Scholar search system (http // scholar.google.com.br). Thirty two works were studied and the use of speech therapy in NICU´s was described in twenty eight of them which presented as procedures the assessment and stimulation of the sensory-motor-oral system, using nonnutritive and nutritive sucking and hearing screening techniques. However, the characteristics of newborns with congenital heart disease and the insertion of the speech therapist into cardiac neonatal ICU are not mentioned, not even the description of the objectives and practice of such professional. The care of patients with congenital heart disease should be differentiated as it has particular features that can undermine the performance concerning feeding. Only one publication followed the inclusion criteria of the present survey. It describes the transition of the direct gastric feeding to breast feeding in preterm newborns with heart disease, with age corrected, in a newborn intensive care unit. It was possible to verify the lack of works published on speech therapy intervention with newborns with heart disease, which indicates the need of new studies on the theme, as the care of such patients should be differentiated once they present particularities that could undermine the performance of feeding.

RESUMO Objetivo: Identificar os parâmetros presentes nos instrumentos de rastreio para a disfagia orofaríngea no acidente vascular encefálico, publicados na literatura. Estratégia de pesquisa: Para a seleção dos estudos, foram utilizados os descritores: transtornos de deglutição, acidente vascular cerebral, rastreio, screening, avaliação e disfagia. Foram consultadas as bases de dados MEDLINE, Embase, LILACS, SciELO e biblioteca Cochrane. Critérios de seleção: Foram selecionados artigos em inglês, português e espanhol, publicados até dezembro de 2014, cuja abordagem metodológica referisse instrumentos de rastreio para a disfagia orofaríngea, elaborados para indivíduos adultos com acidente vascular encefálico. Os parâmetros utilizados nos diferentes instrumentos de rastreio foram agrupados por igualdade e/ou semelhança. Foi realizada análise descritiva e calculada a frequência dos parâmetros encontrados. Resultados: Foram encontrados 688 artigos e, após consideração dos critérios de inclusão e exclusão, 23 artigos foram efetivamente analisados. Dos 20 instrumentos encontrados, 90% utilizaram algum tipo de oferta via oral no rastreio para a disfagia, sendo a maioria, a água. Foram encontrados 19 parâmetros distintos, não relacionados à oferta de alimento e 12 parâmetros relacionados à oferta de alimento. Conclusão: Não há consenso, entre os estudos, sobre os parâmetros mais sensíveis e específicos para compor o método de rastreio para disfagia orofaríngea na população com acidente vascular encefálico.

ABSTRACT Purpose: To identify the parameters present in the screening tools for oropharyngeal dysphagia in stroke published in the literature. Research strategy: For the selection of studies, the swallowing disorder descriptors stroke, screening, evaluation and dysphagia were used. MEDLINE, Embase, LILACS, SciELO and the Cochrane Library databases were consulted. Selection criteria: We selected articles in the English, Portuguese and Spanish languages published up to December 2014 whose methodological approach referred to screening tools for oropharyngeal dysphagia designed for adults with stroke. The parameters used in the various screening tools were grouped by equality and/or likeness. We performed a descriptive analysis and calculated the frequency of found parameters. Results: We found 688 articles and after consideration of the inclusion and exclusion criteria, 23 articles were effectively analyzed. Of the 20 tools found, 90% used some type of food offer orally in screening for dysphagia, mostly water. We found 19 different parameters not related to food offer and 12 parameters related to food offer. Conclusion: There is no consensus among the studies on the most sensitive and specific parameters to compose the screening method for oropharyngeal dysphagia in stroke.

OBJETIVO:associar o grau de disfagia orofaríngea e o tempo de intubação orotraqueal no indivíduo pós-acidente vascular encefálico após cirurgia cardíaca.MÉTODOS:estudo clínico transversal descritivo, retrospectivo, realizado por meio da coleta de dados de protocolos e registros de prontuário, durante seis meses, em Hospital Público de Referência em Cardiologia. Foram analisados 25 protocolos e prontuários de indivíduos submetidos à cirurgia cardíaca, que evoluíram com acidente vascular encefálico e foram assistidos pela equipe de Fonoaudiologia. Os indivíduos foram divididos em dois grupos. O Grupo I (GI) constou de 10 indivíduos com intubação orotraqueal menor que 24 horas e o Grupo II (GII) de 15 indivíduos com intubação orotraqueal maior que 24 horas. Realizada avaliação clínica da deglutição e analisada a associação entre a classificação clínica do grau de comprometimento para disfagia e o tempo de intubação orotraqueal.RESULTADOS:verificou-se que no GI 40% apresentaram disfagia leve, 30% moderada e 20% grave. No GII 13,3% apresentaram disfagia leve, 33,3% moderada e 53,33% grave. Verificou-se associação linear significante entre o grau de disfagia e o tempo de IOT (p= 0,031), indicando que o número de indivíduos com disfagia moderada e grave foi maior no grupo com mais tempo de intubaçao.CONCLUSÕES:constatou-se que o tempo de intubação orotraqueal maior que 24 horas aumentou o grau da disfagia orofaríngea nesta população.

PURPOSE: to associate the degree of oropharyngeal dysphagia and orotracheal intubation time in post stroke individuals after cardiac surgery.METHODS: a cross-sectional retrospective descriptive clinical study carried out by means of protocols data collection and chart records during six months in a public hospital of reference in cardiology. We analyzed 25 protocols and medical records of individuals undergoing cardiac surgery who evolved with stroke and were assisted by a team of speech and language pathology. The subjects were divided into two groups. Group I (GI) consisted of 10 individuals with orotracheal intubation less than 24 hours and Group II (GII) of 15 individuals with orotracheal intubation more than 24 hours. After performing swallowing clinical evaluation and analyzing the association between the clinical classification of degree of commitment for dysphagia and orotracheal intubation time.RESULTS: it was found that 40% of the individuals in GI presented mild dysphagia, 30% moderate and 20% severe. In GII, 13.3 % presented mild dysphagia, 33.3% moderate and 53.33% severe. There was a significant linear association between the degree of dysphagia and the duration of intubation (p = 0.031), indicating that the number of individuals with moderate and severe dysphagia was higher in the group with a longer intubation.CONCLUSIONS: we could observe that time of orotracheal intubation more than 24 hours increases the degree of oropharyngeal dysphagia in this population.

Background: family is basic as a health determinant and it is the most adjusting efficacious net in social life. The fulfillment of its functions is essential for the full development of its members, and for propitiating responsibility and positive attitudes toward study and work. Aim: to characterize family health in Medicine students’ families. Material and methods: we carried out a cross-sectional descriptive research, in 45 families of Medicine students belonging to the University Policlinic Heroes del Moncada, urban area of Cardenas, Matanzas. In the elaboration of the family health history, the techniques of observation and interviewing were used, and also the family functioning perception test for diagnosing family health through the relational dynamic. Results: 60 % are nuclear families and 35,6 % are extensive ones. 64,5 % are median families, followed by the little ones with 15, and 2,2 % are big. 73,3 % of the families are bi-generational and 11 are tri-generational. Nuclear bi-parental families are predominant with 15, being 55,6 %; 7 are reconstituted, for 25,9 % of all the nuclear families, and 5 are monoparental ones. 88,9 % of the total are functional families, and the rest are moderately functional. Conclusions: There it was a predominance of nuclear, bi-generational and median families. The biparental families were the most frequent, followed by the reconstituted ones. In around half of the sample, both parents live together, being married for the first time. There it was a diagnosis prevalence of functional family. No dysfunctional family was diagnosed.

The aim of this study was to investigate sensitivity disorders in the oral cavity related to the presence of Mycobacterium leprae in the saliva of treatment-naïve patients with leprosy in the state of Amazonas, Brazil. A cross-sectional study was conducted involving 45 subjects with leprosy. The subjects were interviewed to evaluate the sensitivity of the oral cavity. For the detection of M. leprae, saliva and slit-skin smear samples were collected. The samples were analysed using a bacteriological index (BI) protocol and the real-time quantitative polymerase chain reaction (qPCR). The results indicated that 15 of the 45 (33.3%) subjects with leprosy showed decreased oral sensitivity, which confirmed the importance of the oral cavity sensitivity evaluation. There was not a direct relationship between the presence of M. leprae in saliva and changes in oral sensitivity. Positive saliva qPCR results from six (31.6%) of 19 paucibacillary (PB) patients suggested the possibility of a new site for sample collection. Positive results using these diagnostic techniques (BI, slit-skin smear and saliva qPCR) increased to 55.5%, thus opening the possibility of combining these different techniques to increase the rate of positive diagnoses, especially in PB patients.
