Avaliação cefalométrica das alterações transversais e verticais ocorridas em pacientes submetidos à expansão rápida da maxila assistida cirurgicamente

O objetivo desta pesquisa foi de avaliar as alterações dentárias e esqueléticas nos sentidos transversal e vertical produzidas pela Expansão Rápida da Maxila Assistida Cirurgicamente (ERM-AC). A amostra foi composta por 17 pacientes com idade média de 24 anos e 1 mês, sendo 11 do sexo feminino e 6 do masculino, que apresentavam uma deficiência de crescimento transversal da maxila, e não tinham sido submetidos a tratamento ortodôntico previamente e necessitavam de ERM-AC como parte de seus tratamentos ortodônticos. Todos os pacientes foram radiografados nas fases pré-expansão, imediatamente após o período de três meses de contenção com o próprio aparelho, totalizando assim uma amostra de 51 telerradiografias em normal frontal. Medidas angulares e lineares foram obtidas a partir dos traçados cefalométricos e analisadas estatisticamente. Concluiu-se que a ERM-AC produziu um aumento da cavidade nasal e da largura maxilar, que permaneceu constante após o período de três meses de contenção. As distâncias intermolares superior e inferior aumentaram após a expansão da maxila, e se mantiveram estáveis, durante o período de contenção. Houve afastamento entre os incisivos centrais superiores, sendo o movimento maior em nível apical em relação às coroas, o que produziu uma divergência das raízes após a expansão. Após o período de contenção, houve maior movimento das coroas às suas posições originais. Avaliando o comportamento vertical da face, notou-se um aumento da altura facial ântero-inferior. (AU)

AVALIAÇÃO DA INFLUÊNCIA DO TIPO FACIAL NOS TAMANHOS DOS ESPAÇOS AÉREOS NASO E BUCOFARÍNGE

A variação nos tamanhos dos espaços aéreos naso e bucofaríngeo ocorre devido a fatores genéticos e/ou ambientais. A diminuição no tamanho do espaço aéreo nasofaríngeo, causada pela hipertrofia da tonsila faríngea, tem sido associada a alterações no padrão normal de crescimento craniofacial e a efeitos deletérios na oclusão. O objetivo do presente trabalho é avaliar se há variação nos tamanhos dos espaços aéreos naso e bucofaríngeo de acordo com o padrão de crescimento craniofacial, assim como avaliar a correlação entre os tamanhos dos espaços e o índice VERT, além de verificar um possível dimorfismo sexual. Na mensuração dos espaços, utilizou-se telerradiografias laterais de 90 pacientes, divididos em três grupos de acordo com o padrão de crescimento craniofacial, determinado por meio do índice VERT de Ricketts. Os pacientes da amostra, com idades entre 9 e 16 anos, apresentavam padrão respiratório nasal, sem qualquer tipo de obstrução. Não foi observada variação estatisticamente significante nos tamanhos dos espaços aéreos naso e bucofaríngeo, quando comparados os três tipos faciais. Também não foi encontrada correlação entre os tamanhos dos espaços aéreos e os valores do índice VERT de Ricketts dos pacientes e não foi observado dimorfismo sexual. XII

Avaliação do Índice de Maturação das Vértebras Cervicais em radiografias cefalométricas laterais, tomadas com diferentes posicionamentos de cabeça

Este trabalho teve como finalidade avaliar a fase de crescimento em uma amostra de 49 pacientes, com idades variando de 9 a 15 anos, observando as vértebras cervicais em radiografias laterais, tomadas na posição natural de cabeça (PNC) e com erros de posicionamento, com inclinações de cabeça de 15o para cima (PNC-Alta) e de 15 o para baixo (PNC-Baixa), visando definir o quão importante isto é na precisão da avaliação da fase de crescimento. O teste kappa ponderado mostrou um grau de concordância substancial entre PNC e PNC-Alta e entre PNC e PNC-Baixa. Já o teste não paramétrico de wilcoxon (p<0,05) mostrou diferença estatisticamente significante entre essas comparações. Desta forma, a PNC demonstrou ser mais confiável na avaliação do Índice de Maturação das Vértebras Cervicais (IMVC), porém as telerradiografias com erro de posicionamento avaliadas não tiveram um grau de discordância que indicasse sua não utilização na clínica para predição de crescimento.(AU)

AVALIAÇÃO DA ESTABILIDADE DAS ALTERAÇÕES TRANSVERSAIS PROMOVIDAS PELO APARELHO REGULADOR DE FUNÇÃO FRANKEL 2, POR MEIO DE TELERRADIOGRAFIAS POSTEROANTERIORES

O objetivo desta pesquisa constituiu em avaliar, por meio das telerradiografias posteroanteriores, as alterações transversais promovidas pelo aparelho Frankel-2 em pacientes com maloclusão de Classe II, divisão 1, além de verificar a estabilidade das mesmas após um período médio de 7,11 anos pós-tratamento. A amostra compreendeu um total de 45 telerradiografias posteroanteriores provenientes de 15 pacientes tratados com o RF-2, realizadas em três fases: (T1) início do tratamento; (T2) final de tratamento; (T3) pós-tratamento. Foram avaliadas outras 36 telerradiografias posteroanteriores de 18 pacientes não tratados (grupo controle), acompanhados num período correspondente ao tratamento (T1-T2). As telerradiografias foram digitalizadas e foi utilizado o software Radiocef Studio 2 para realizar as mensurações das medidas cefalométricas. Para a comparação entre as alterações ocorridas no grupo tratado e no grupo controle, foi aplicado o teste t não pareado. Já para as modificações nas fases inicial, final e pós-tratamento no grupo tratado, foi empregada a Análise de Variância seguida do teste de comparações múltiplas de Tukey, com o valor crítico de 0,05. Os resultados mostraram que durante o período de tratamento as distâncias intercaninos inferiores e intermolares superiores aumentaram de forma estatisticamente significante. Já as distâncias que representam a largura da cavidade nasal, altura facial inferior, largura mandibular e distância intermolares inferiores não sofreram alterações estatisticamente significantes. No período pós-tratamento, observou-se uma suave redução nas distâncias intercaninos inferiores e intermolares superiores. Porém, considerando-se as alterações ocorridas devido ao crescimento e desenvolvimento transversal dos arcos dentários no período analisado, em que haveria uma redução destas distâncias, provavelmente houve uma estabilidade relativa das alterações dentárias transversais promovidas pelo RF-2. Portanto, pode-se concluir que o RF-2 não possui qualquer efeito esquelético transversal. Contudo, há um aumento das distâncias intermolares superiores e intercaninos inferiores durante o tratamento, que permanece relativamente estável, considerando-se as alterações ocorridas pelo crescimento e desenvolvimento normal dos arcos dentários.

AVALIAÇÃO DAS ALTERAÇÕES DENTOESQUELÉTICAS DECORRENTES DO TRATAMENTO DA MALOCLUSÃO DE CLASSE II COM O APARELHO FORSUS POR MEIO DE TOMOGRAFIA COMPUTADORIZADA

Este estudo teve como objetivo avaliar cefalometricamente as alterações dentoesqueléticas decorrentes do tratamento da maloclusão de Classe II, divisão 1, com o aparelho Forsus®, por meio de Tomografia Computadorizada de Feixe Cônico (TCFC). O grupo avaliado foi composto por 10 pacientes, sendo 7 do sexo masculino e 3 do sexo feminino, com idade média de 16,1 anos, maloclusão com severidade mínima de 1/2 Classe II, trespasse horizontal mínimo de 5 mm, padrão facial meso ou braquifacial. Estes jovens se encontravam no estágio IV ou V de maturação óssea, verificada pelas vértebras cervicais. O tempo de uso do aparelho Forsus foi de 7,16 meses (média), período de avaliação compreendido entre a aquisição da primeira teleradiografia gerada através da TCFC (T1 - pré-Forsus) e da segunda teleradiografia (T2 - pós-Forsus). Para análise estatística foi utilizado o teste-t pareado. Os resultados mostraram um pequeno crescimento mandibular que, juntamente com uma diminuição do SNA levaram a uma melhora da relação maxilomandibular. Houve uma rotação no sentido anti-horário da mandíbula e do plano oclusal no sentido horário. Os incisivos superiores foram retruídos, verticalizados e extruídos e os molares superiores distalizaram por inclinação. Houve vestibularização, protrusão e intrusão dos incisivos inferiores, além de mesialização e extrusão dos molares inferiores. Desta maneira, conclui-se que o aparelho Forsus foi efetivo na correção da maloclusão de Classe II, propiciando maiores alterações dentoalveolares do que esqueléticas.(AU)

Avaliação das Capacidades de Timing e Seletividade dos Gestores de Fundos de Ações em Períodos de Crise: Evidência Empírica para o Mercado Português

Os fundos de investimento mobiliários são uma boa alternativa para os aforradores diversificarem as suas poupanças, em particular que investem em ações. Esta classe de fundos visa proporcionar ao investidor o acesso a uma aplicação com uma elevada expectativa de rendibilidade a longo prazo. Dentro da oferta deste tipo de fundos domiciliados em Portugal, a questão fundamental é saber quais os mais apropriados para investir. Com este trabalho, pretende-se contribuir para o conhecimento da qualidade da gestão desta classe de ativos e, assim, fornecer mais elementos aos investidores para uma melhor tomada de decisão. Deste modo, esta investigação avalia as capacidades de timing e seletividade dos gestores de fundos de ações domiciliados em Portugal, em períodos de crise e não-crise, bem como os seus estilos de investimento. O estudo incide sobre o período de janeiro de 2000 a dezembro de 2014 e inclui todos os fundos, sobreviventes e não sobreviventes, que estiveram em atividade durante um período mínimo de 24 meses. Os resultados sugerem uma reduzida capacidade de timing e a inexistência de capacidades de seletividade por parte dos gestores. De um modo geral, as capacidades de seletividade são melhores nos períodos de não-crise do que nos períodos de crise, enquanto as capacidades de timing são, na maior parte dos casos, idênticas em diferentes estados do mercado. Em relação aos estilos de investimento, verifica-se uma maior predominância de ações com pequenas capitalizações nas carteiras, com maior incidência nos períodos de crise. Verifica-se, também, uma preferência dos gestores dos fundos que investem em Portugal e na Europa por ações de rendimento e uma preferência dos restantes gestores por ações de crescimento, sendo estas tendências mais vincadas em alturas de crise.

Avaliação da atividade anti-Helicobacter pylori e citotóxica in vitro de extratos orgânicos obtidos das folhas de Encholirium spectabile e Syzygium cumini

Helicobacter pylori is a spiral, Gram negative, mobile, and microaerophilic bacteria recognized as a major cause of gastritis, ulcer, gastric cancer, and gastric low grade, B cell, mucosa – associated lymphoid tissue (MALT) lymphoma, constituting an important microorganism in medical microbiology. Its importance comes from the difficulty of treatment because the requirement of multiple drugs use, besides the increasing emergence of resistant and multiresistant strains to antibiotics used in th e clinic. In order to expand safe and effective therapeutic options , chemical studies on medicinal plants by obtaining extracts, fractions, isolated compounds or essential oils with some biological activity has been intensified . Given the above, the objective was to evaluate the inhi bitory activity of organic extracts derived from Syzygium cumini and Encholirium spectabile, with antiulcer history, and the essential oil, obtained from S. cumini, against H. pylori (ATCC 43504) by the disk diffusion method, for qualitative evaluation, an d determination of minimum inhibitory concentration (MIC) using the broth microdilution method, for quantitative analysis. Also was evaluated the extracts in vitro toxicity by a hemolytic assay using sheep red blood cells, and VERO and HeLa cells using the MTT assay to analyze cell viability. The extracts of both plant used in antimicrobial assays did not inhibit bacterial growth, however the essential oil of S. cumini (SCFO) proved effective, showing MIC value of 205 μg/mL (0.024 % dilution of the original oil). In the hemolytic assay, the same oil shows moderate toxicity, by promote 25% hemolysis at 1000 μg/mL. Regarding the cytotoxicity in cell culture, the SCFO, at 260 μg/mL, affected the cell viability around 80% of HeLa and 50% of VERO cells. So the oi l obtained from S. cumini leaves has antimicrobial activity against H. pylori and cytotoxicity potential, suggesting a source of new molecule drug candidates, since new stages of toxicity in vitro and in vivo, as well, chemical characterization be evaluate d. Moreover, the development of a prospective drug delivery system can result in a prototype to be used in preclinical tests.

Políticas públicas de economia solidária: uma avaliação do PCPR II na microrregião de Angicos do Rio Grande do Norte

The Solidarity Economy is considered in this work as a development option. Talk about it is to think in the workforce as a producer of material wealth and, above all , subjective , therefore it is necessary to take into account that these relations coexist different types of practices that encompass emotions , lifestyles , etc. This research has as an object of study evaluating the effectiveness of public policy for Solidarity Economy, microrregion Angicos / RN, demonstrating how the Solidarity Economy has encouraged the development not only as a driving force for economic growth, but as the expansion capabilities and freedoms. The Solidarity Economy has several definitions, and despite having its origin in the cooperative movement, is a concept under construction. Focused on the discussion of public policy, is now understood as a proposal for employability, either as a generator of employment and income, reflecting its polymorphism. Theories and concepts developed by Amartya Sen is an important analytical tool for understanding the Solidarity Economy as a development strategy. When speaking of instrumental freedoms, Senniana theory contributes to reflection on how participants socioeconomic actions are becoming active agents of change i n their own freedoms. The analysis was based on the discussion of development beyond economic bias, using the lines of the vari ous local stakeholders with PCPR II, p hase 2, for microrregion Angicos / RN, comprising: public managers, technical advisors and beneficiaries of the program rural poverty alleviation. Besides the discussion of the economic organization of the RN and its spatial distribution, the survey brings the result that the Solidarity Economy in microrregion Angicos / RN contributed to the dev elopment as freedom, proving the effectiveness of public policy by allowing an improvement in the quality of life, enabling efetivations, even without major proportions.

Avaliação imuno-histoquímica das proteínas BMP-4, FGF-8 e Sindecan-1 em tumores odontogênicos

The development and progression of odontogenic tumors have been associated with an imbalance in the activity of growth factors, adhesion molecules, extracellular matrix proteins and their degradation enzymes, angiogenic factors and osteolytic. Some studies have shown that interaction relationships inductive epithelial / mesenchymal determinants of Odontogenesis are mimicked by these tumors. The objective of this research was to investigate the immunolocalization of growth factors (BMP-4 and FGF-8) and Sindecan-1 structural protein in a series of odontogenic tumors presenting different biological behaviors, to contribute to a better understanding of the role of these proteins in tumor development. The sample consisted of 21 of the solid ameloblastoma, odontogenic keratocysts 19 and 14 odontogenic adenomatoid tumors. Increased Sindecan-1 immunostaining was seen in the epithelium of the lesions when compared with mesenchyme. In ameloblastoma and odontogenic keratocysts, this expression was higher than in AOT. Epithelial expression of BMP4 showed quantitatively similar in the three studied lesions; however, when anlisada mesenchymal immunoreactivity, was detected significant higher expression when compared to the ameloblastoma keratocysts. In ameloblastoma, mesenchymal expression was predominantly (p = 0.008), while in keratocyst higher expression in the epithelium was observed (p = 0.046). In all injuries, strong or moderate correlation was observed in the BMP-4 immunoreactivity in the epithelium and mesenchyme. FGF-8, no injury was observed difference between the immunoreactivity in the epithelium or mesenchyme, however in ameloblastoma positive correlation was found (Spearman correlation, rho = 0.857, p <0.001). The results of this study suggest that the three evaluated biomarkers actively involved in the pathogenesis of lesions, especially the expression of ameloblastomas indicating a strong interaction between parenchymal and stromal cells which may contribute to its marked aggressiveness.

Avaliação da concentração de vitamina A materna e de neonatos prematuros e a termo

Vitamin A is an essential nutrient for many physiological processes such as growth and development, so that their adequate nutritional state is essential during pregnancy and lactation. Lactating women and children in breastfeeding are considered risk groups for vitamin A deficiency and some factors may increase the risk of vitamin A deficiency, such as prematurity. The aim of this work was to evaluate the vitamin A concentration in preterm and term lactating women and newborns by determination of retinol in maternal serum, umbilical cord serum and breast milk collected until 72 hours postpartum. 182 mothers were recruited and divided into preterm group (GPT; n = 118) and term group (GT, n = 64). In preterm group were also analyzed transition milk (7th-15th day; n = 68) and mature milk (30th-55th day; n = 46) samples. Retinol was analyzed by high-performance liquid chromatography (HPLC). Maternal retinol concentration in serum was 48.6 ± 12.3 µg/dL in GPT and 42.8 ± 16.3 µg/dL in the GT (p <0.01). Cord serum retinol was 20.4 ± 7.4 µg/dL in GPT and 23.2 ± 7.6 µg/dL in GT (p> 0.05). Among newborns, 43% of premature and 36% of term had low levels of serum retinol in umbilical cord (<20 µg/dL). In colostrum, the retinol in preterm and term groups had an average of 100.8 ± 49.0 µg/dL and 127.5 ± 65.1 µg/dL, respectively (p <0.05). The retinol average in preterm milk increased to 112.5 ± 49.7 µg/dL in transition phase and decreased to 57.2 ± 23.4 µg/dL in mature milk, differing significantly in all stages (p <0.05). When comparing with the recommendation of vitamin A intake (400 µg/day) GT colostrum reached the recommendation for infants, but in GPT the recommendation was not achieved at any stage. Mothers of premature infants had higher serum retinol than mothers at term; however, this was not reflected in serum retinol of umbilical cord, since premature had lower concentration of retinol. Such condition can be explained due to lower maternal physiological hemodilution and placental transfer of retinol to the fetus during preterm gestation. Comparison of retinol in colostrum showed lower concentrations in GPT; however the transition phase there was a significant increase of retinol content released by the mammary gland of preterm mothers. This situation highlights a specific physiological adaptation of prematurity, likely to more contribute to formation of hepatic reserves of retinol in premature infants.

Avaliação da atividade antimicrobiana das defensinas recombinantes de ervilha (drr230a) e café (cd1) produzidas em Pichia pastoris

The inefficiency of chemical pesticides to control phytopathogenic fungi in agriculture and the frequent incidence of human diseases caused by bacteria which are resistant to antibiotics lead to the search for alternative antimicrobial compounds. In this context, plant defensins are a promising tool for the control of both plant and human pathogenic agents. Plant defensins are cationic peptides of about 50 amino acid residues, rich in cysteine and whose tridimensional structure is considerably conserved among different plant species. These antimicrobial molecules represent an important innate component from plant defense response against pathogens and are expressed in various plant tissues, such as leaves, tubers, flowers, pods and seeds. The present work aimed at the evaluation of the antimicrobial activity of two plant defensins against different phytopathogenic fungi and pathogenic bacteria to humans. The defensin Drr230a, whose gene was isolated from pea (Pisum sativum), and the defensin CD1,whose gene was identified within coffee (Coffea arabica) transcriptome, were subcloned in yeast expression vector and expressed in Pichia pastoris. The gene cd1 was subcloned as two different recombinant forms: CD1tC, containing a six-histidine sequence (6xHis) at the peptide C-terminal region and CD1tN, containing 6xHis coding sequence at the N-terminal region. In the case of the defensin Drr230a, the 6xHis coding sequence was inserted only at the N-terminal region. Assays of the antimicrobial activity of the purified recombinant proteins rDrr230a and rCD1 against Phakopsora pachyrhizi, causal agent of soybean Asian rust, were performed to analyze the in vitro spore germination inhibition and disease severity caused by the fungus in planta. Both recombinant defensins were able to inhibit P. pachyrhizi uredospore germination, with no difference between the antimicrobial action of either CD1tC or CD1tN. Moreover, rDrr230a and rCD1 drastically reduced severity of soybean Asian rust, as demonstrated by in planta assays. In spite of the fact that rCD1 was not able to inhibit proliferation of the human pathogenic bacteria Staplylococcus aureus and Klebsiella pneumoniae, rCD1 was able to inhibit growth of the phytopathogenic fungus Fusarium tucumaniae, that causes soybean sudden death syndrome. The obtained results show that these plant defensins are useful candidates to be used in plant genetic engineering programs to control agriculture impacting fungal diseases.

Métodos de avaliação nutricional para a suplementação oral com zinco em crianças pré-púberes não deficientes em zinco

Background: Zinc is an essential nutrient that is required for numerous metabolic functions, and zinc deficiency results in growth retardation, cellmediated immune dysfunction, and cognitive impairment. Objective: This study evaluated nutritional assessment methods for zinc supplementation in prepubertal nonzinc- deficient children. Design: We performed a randomised, controlled, triple-blind study. The children were divided into a control group (10% sorbitol, n = 31) and an experimental group (10 mg Zn/day, n = 31) for 3 months. Anthropometric and dietary assessments as well as bioelectrical measurements were performed in all children. Results: Our study showed (1) an increased body mass index for age and an increased phase angle in the experimental group; (2) a positive correlation between nutritional assessment parameters in both groups; (3) increased soft tissue, and mainly fat-free mass, in the body composition of the experimental group, as determined using bioelectrical impedance vector analysis; (4) increased consumption of all nutrients, including zinc, in the experimental group; and (5) an increased serum zinc concentration in both groups (p < 0.0001). Conclusions: Given that a reference for body composition analysis does not exist for intervention studies, longitudinal studies are needed to investigate vector migration during zinc supplementation. These results reinforce the importance of employing multiple techniques to assess the nutritional status of populations.

Avaliação multidimensional da qualidade de vida em idosos: um estudo no Curimataú ocidental paraibano

The fast growth of the elderly population is a reality throughout the world and has become one of the greatest challenges for contemporary public health. When considering the increased life expectancy and the aging as a multidimensional phenomenon, one should highlight the need to investigate if the increase of longevity is associated with satisfactory levels of Quality of Life (QOL). This study has the objective of assessing the QOL of elderly people from the Paraíba’s Western Curimataú microregion, explained by its health and living conditions. This is a cross-sectional and observational study with quantitative design held with 444 elderly people from five cities: Barra de Santa Rosa, Cuité, Nova Floresta, Remígio e Sossego. In order to obtain information, the following instruments were used: I) Questionnaire for collection data related to the elderly population, for sociodemographic, clinical and behavioral characteristics; and II) WHOQOL-Old questionnaire, with a view to measuring and assessing QOL. Data were processed on the IBM-SPSS Statistics 20.0 software by means of the ANOVA (one-way), Student’s t, Mann-Whitney, Kruskal-Wallis and Pearson’s correlation tests, with p-values<0,05 accepted as being statistically significant. The results indicate a good global QOL (ETT=65,69%), with better assessment by elderly men, aged between 60 and 74 years, married, living with partner and children, without caregiver, physical activity practitioners, with up to one health problem before an aspect of multimorbidity and with very good and/or good assessment of basic needs. The self-reported stress showed a negative significant correlation before the global QOL, where the greater the perception of stress, the worse the assessment of QOL. In the faceted assessment of QOL, the Sensory Operation showed the best performance (ETF= 68,86%) and the Social Participation (SP) the worst (ETF=60,37%). In the multiple linear regression model, SP is singly responsible for 51,8% (R2=0,518) of explanation of the global QOL. In the intercorrelation among the WHOQOL-Old facets, only Death and Dying did not reveal significance. The harmony highlighted among the facets raises the need to ensure a comprehensive health care for the elderly population, especially in understanding the social participation as an intrinsic part of the QOL and that it requires the re-discussion and reconstruction of individual and collective, family and community, political and government actions. Hence, guaranteeing an active, healthy and participatory aging, with QOL, is the major challenge.
