Abstract To evaluate the effect of combining 5% hydrofluoric acid (HF) and silane (SI) with the self-etching ceramic primer on the immediate and after 1-year of water storage on bonding efficacy, conditioning pattern (CP) and chemical interaction (CI) to the lithium disilicate. A total of 16 CAD/CAM blocks of lithium disilicate (LD) were cut into four square sections (n=64). For bonding efficacy evaluation, the LD specimens were divided into 4 groups (n=10): 1) HF+SI; 2) self-etching ceramic primer (MEP); 3) HF+MEP; 4) MEP+SI. After each treatment, an adhesive system was applied and Tygon matrices were filled with a dual-cured resin cement followed by light curing. Cylinder specimens (0.8 mmx0.5mm) were stored in water (37 °C for 24 h or 1-year) and submitted to the μSBS test (2-way ANOVA and Tukey’s test; a=0.05). CP and CI were only evaluated qualitatively. No significant difference on the μSBS was observed between groups (p=0.73), but reduced μSBS was observed after 1-year of water storage (p>0.0001). After application of HF+SI and MEP, reduction in a number of siloxane bonds was observed, suggesting the coupling of SI on the LD surface. HF or HF+MEP produced a higher dissolution of the glassy matrix than the use of MEP alone. The MEP can be an alternative to traditional ceramic treatment once the chemical interaction and long-term bond strength were similar between both groups. The association of hydrofluoric acid or silane with a self-etching ceramic primer did not add any benefits in terms of chemical interaction and bonding stability.

Abstract Cleft lip, alveolus and palate is a congenital malformation caused by the lack of fusion of the lip and palate embryonic processes, which may disrupt the main functions of the stomatognathic system. Aim: This study aimed to assess the orofacial dysfunction in individuals with cleft lip, alveolus, and palate compared to non-cleft patients. One hundred and twenty individuals between 32 and 65 years of age were selected in the Craniofacial Center and in the School of Dentistry and divided into two groups: non-cleft patients (N-CLAP) and cleft lip, alveolus, and palate patients (CLAP). The two groups were matched by gender. Each individual was interviewed and submitted to a clinical evaluation during which the NOT-S was used to assess orofacial dysfunction. To verify the intra-examiner agreement, the values were compared using the Kappa test. The Mann-Whitney test compared performance on the NOT-S between the groups. The Chi-Square test compared the NOT-S domains between the groups. A comparison of the NOT-S scores between the groups revealed statistically significant differences in gender (p<0.001), but no statistically significant differences in the intragroup gender comparison were found. The assessment of the NOT-S domains between the N-CLAP and CLAP groups exhibited statistically significant differences in domains: breathing (p=0.021), chewing and swallowing (p<0.001), and dryness of the mouth (p=0.002) of the interview and significant differences in all domains of the clinical examination (p<0.001). Individuals with CLAP showed more orofacial dysfunction than non-cleft patients, without gender differences, after being assessed through the NOT-S.

Published: April 2019

ABSTRACT: Coffee crops play an important role in Brazilian agriculture, with a high level of social and economic participation resulting from the jobs created in the supply chain and from the income obtained by producers and the revenue generated for the country from coffee bean export. In coffee plant growth, leaves have a determinant role in higher production; therefore, the leaf count per plant provides relevant information to producers for adequate crop management, such as foliar fertilizer applications. To describe count data, the Poisson model is the most commonly employed model; when count data show overdispersion, the negative binomial model has been determined to be more adequate. The objective of this study was to compare the fitness of the Poisson and negative binomial models to data on the leaf count per plant in coffee seedlings. Data were collected from an experiment with a randomized block design with 30 treatments and three replicates and four plants per plot. Data from only one treatment, in which the number of leaves was counted over time, were employed. The first count was conducted on 8 April 2016, and the other counts were performed 18, 32, 47, 62, 76, 95, 116, 133, and 153 days after the first evaluation, for a total of ten measurements. The fitness of the models was assessed based on deviance values and simulated envelopes for residuals. Results of fitness assessment indicated that the Poisson model was inadequate for describing the data due to overdispersion. The negative binomial model adequately fitted the observations and was indicated to describe the number of leaves of coffee plants. Based on the negative binomial model, the expected relative increase in the number of leaves was 0.9768% per day.

ABSTRACT Introduction: Physical training is recommended by current guidelines as a preventive measure and as a tool to supplement pharmacological therapy in the treatment of hypertension and its pathological manifestations. However, there is considerable uncertainty regarding the best training prescription for blood pressure control in patients with resistant hypertension. Objective: To evaluate the effect, over twelve weeks, of an aerobic and resistance exercise program on blood pressure, anthropometric and biochemical parameters of patients with resistant hypertension. Methods: Eleven patients with resistant hypertension were randomly divided into two groups: resistance training and aerobic training. Blood pressure was recorded by 24-hour outpatient monitoring before and after 12-week training. The Student t-test was used to compare resistance and aerobic exercise groups, while the paired t and Wilcoxon tests were used to analyze pre- and post-exercise data. The level of significance was 0.05. Results: In the group that underwent aerobic training, mean systolic, diastolic and total blood pressure readings were significantly lower over the 24 hours analyzed, dropping by 14 mmHg, 7 mmHg and 10 mmHg, respectively, and in the waking period. The resistance training group showed no significant change in blood pressure, despite the significant improvement in HDL levels. Conclusion: Twelve weeks of aerobic exercises resulted in significantly lowered blood pressure in individuals with resistant hypertension, while resistance exercises were more effective in increasing HDL.

ABSTRACT Introduction: Aging causes alterations in various executive and cognitive functions, mainly related to the incidence of dementia, especially Alzheimer's disease (AD). Several studies mention physical exercise as a preventive resource for depressive symptoms. Objective: To investigate the cognitive and behavioral alterations related to AD that are capable of slowing disease progression and its complications. Methods: The sample consisted of 10 male Wistar rats, divided into 2 groups (n = 5), swimming and Alzheimer + swimming, with a 6-day intervention protocol. The elevated plus maze test was used to assess anxiety, the Morris water maze for spatial memory, the isolation box for aversive memory, and the open field test to assay motor behavior. Results: There was improvement in spatial memory in the Swimming group (169 ± 142.9 x 24.2 ± 31.3), but motor behavior deteriorated after exercise. An increase in anxious behavior (8 ± 13.03 x 67.8 ± 48.1) was observed in the animals with AD. This is a relevant characteristic of the disease, which did not improve after acute exercise. By analyzing the size effect, it was possible to observe a difference in the Alzheimer + swimming group in terms of reduced anxiety and improved motor behavior after exercise. Despite the benefits of physical exercise for AD symptoms, there is still no consensus on the type of physical exercise and length of intervention necessary to achieve a positive response as a treatment method, since studies are yet to confirm this fact in an acute or chronic manner. Conclusion: Acute physical exercise was not fully effective as a means of treating behavioral alterations related to AD, but had a mean effect on the size effect analysis of motor behavior and anxiety, specifically.

RESUMO O objetivo deste estudo foi descrever características de sucesso e insucesso do uso da ventilação não invasiva (VNI) na unidade de terapia intensiva (UTI) de um hospital universitário. Trata-se de um estudo observacional prospectivo no qual foram incluídos 75 pacientes, com idade média de 58,3±18,8 anos. Desses, doze necessitaram do uso da VNI por mais de uma vez, totalizando 92 utilizações. Evidenciou-se que, delas, a taxa de sucesso foi de 60,9% (56). O grupo insucesso apresentou mais indivíduos do sexo masculino (p=0,006) e número maior de pacientes com diagnóstico de infecção extrapulmonar (p=0,012). Não foram encontradas diferenças entre os grupos de sucesso e insucesso nos quesitos de modo, modelo, máscara, tempo total de permanência e razões para a instalação da VNI. No grupo insucesso, a pressão positiva inspiratória nas vias aéreas (Ipap) e o volume corrente (VC) foram superiores (p=0,029 e p=0,011, respectivamente). A saturação periférica de oxigênio (p=0,047), o pH (p=0,004), base excess (p=0,006) e o bicarbonato (p=0,013) apresentaram valores inferiores. Concluiu-se que os indivíduos do sexo masculino com diagnóstico de infecção extrapulmonar e que evoluíram com acidose metabólica evoluíram com mais insucesso na utilização da VNI. Esses, necessitaram de parâmetros elevados de Ipap e VC.

RESUMO O Acidente Vascular Encefálico (AVE) é uma patologia que frequentemente causa limitações motoras nos Membros Superiores (MMSS) gerando prejuízos funcionais nos movimentos de alcance. O objetivo do estudo foi analisar o recrutamento muscular do membro superior parético durante três condições de alcance: ativo, ativo-assistido e autoassistido, através de dados eletromiográficos das fibras anteriores do Músculo Deltoide (MD), Bíceps Braquial (BB) e Tríceps Braquial (TB). Estudo do tipo transversal que utilizou como testes clínicos o miniexame do estado mental, escala de equilíbrio de Berg, medida de independência funcional, escala modificada de Ashworth e escala de Fugl-Meyer - seção MMSS. A coleta dos dados eletromiográficos de superfície foi realizada utilizando-se o eletromiógrafo e eletrodos de configuração bipolar da EMG System do Brasil com três canais posicionados nos pontos motores do MD (fibras anteriores), BB e TB de ambos os membros superiores. As variáveis clínicas apresentaram resultados de comprometimento motor, cognitivo e funcional leves. Os dados eletromiográficos mostraram que o MD e TB durante o alcance ativo-assistido contraíram mais que no alcance autoassistido (p<0.05). Os MD e TB apresentaram diferenças significativas durante os movimentos de alcance, enquanto que o músculo BB não mostrou alterações. Entre os diversos tipos de alcance, o ativo-assistido foi o que proporcionou maior ativação muscular. Sugere-se que sejam feitos ensaios clínicos para verificar a eficácia dos treinamentos.

ABSTRACT Objective: to reflect on Maurice Merleau-Ponty’s notion of intersubjectivity as a potential reference to researches and actions directed to human care. Method: a reflexive analysis addressing three thematic areas: intersubjectivity and the holistic care; intersubjectivity and interdisciplinarity within the context of care; and description of experiences related to the own body within the context of health care. Results: the discussion presents structuring elements of Merleau-Ponty’s notion of intersubjectivity, such as: dialogue, respect, bond, and language. On the other hand, it reveals ambiguities inherent in the connection of life and culture worlds, created in the intersubjectivity, resulting in different profiles of care, considering its potential to create interdisciplinarity and integrity within the context of health practices. Conclusion: intersubjectivity can contribute by making more creative and innovative the care with ourselves, the others, and the world.

Resumo O trabalho tem um papel fundamental para o ser humano se manter socialmente produtivo e reco-nhecido. Neste contexto, a saúde mental tem recebido uma atenção diferenciada nas últimas décadas. Em meio à precarização, desvalorização do trabalhador, inovações tecnológicas e iminência do desemprego, ocorrem impactos negativos na saúde do trabalhador e, consequentemente, um maior índice de afastamentos por doenças psíquicas. Esta pesquisa objetivou compreender como funciona a assistência à saúde mental do trabalhador no Sistema Único de Saúde em um município do interior do Ceará e se há estabelecimento do nexo causal entre saúde, doença e trabalho. Para tanto, foi realizada uma pesquisa de abordagem qualitativa, que contou com 12 participantes ‒ usuários e profissionais que responderam a um roteiro de entrevista semiestruturado. As informações dos profissionais foram analisadas no software Iramuteq e as dos usuários foram submetidas à análise de conteúdo de Bardin. Os resultados apontam falhas nas ações propostas pelo Centro de Referência em Saúde do Trabalhador, desarticulação dos serviços na rede, dificuldade de investigação do nexo causal e consequente subnotificação dos casos. Conclui-se que é necessário construir articulações entre serviços de saúde para ter uma atenção mais integral em saúde.

Mechanical tests on Corymbia citriodora battenboard panels coated and reinforced with giant bamboo veneers
Authors: Ostapiv Fabiano
Published: April 2019

ABSTRACT Dense wood batten panels usually break in the glue line when loaded. This study demonstrates that thin veneers obtained from mature culms of Dendrocalamus asper by mechanical grinding are suitable for coating and reinforcing solid processed eucalyptus wood and eucalyptus batten panels. Tensile and bending tests were carried out on Corymbia citriodora timber and edge glued batten panels, with and without bamboo veneer reinforcement. The tensile test results showed that the bamboo veneers glued onto the wood and edge glued batten panels specimens acted as a mechanical reinforcement for both cases, when submitted to tensile forces parallel to the bamboo fibers. In bending tests, the edge glued batten panels specimens were tested transversally to the glue line, direction in which the panel showed the lowest mechanical resistance. The edge glued batten panels specimens without reinforcement with laminated bamboo exhibited a fragile behavior and ruptured abruptly along the glue line. A significant increase in the mechanical strength of the set was observed for the edge glued batten panels coated with laminated bamboo. In addition, the mechanical behavior changed in reinforced specimens, which ruptured slowly and gradually in the bending tests.

Published: April 2019

ABSTRACT Bamboo is an abundant plant in tropical regions, which can be used as a nonconventional structural material; however, there is a high variability in its mechanical properties. This study aimed to evaluate the influence of the moisture content and of the sections (with and without node) on the tensile strength parallel to the culm fibers of three bamboo species (Dendrocalamus asper, Phyllostachys pubescens and Phyllostachys aurea), aiming at their use for structural purposes. For each moisture condition (ambient, saturated in water, oven dried and control), a completely randomized design, following a 3 x 2 factorial scheme, was used. Phyllostachys pubescens exhibited a higher tensile strength parallel to the fibers than the other species. In general, the node affected negatively the tensile strength parallel to the fibers for all analyzed conditions, while the moisture content did not show a significant influence, although the descriptive analysis exhibited its influence on the dimensional variations and water absorption.

Published: April 2019

ABSTRACT Different irrigation times result in variable transpiration rates, due to the water availability and its interaction with the evapotranspiration demand. The vapor pressure deficit is an accurate indicator of the atmosfere evaporative capacity and can affect plants because of the movement of water in the soil-plant-atmosphere continuum system. This study aimed to evaluate the plant growth, yield and water-use efficiency of bell peppers under irrigation times (8 a.m. and 2 p.m.) and water replacement levels (60 %, 80 %, 100 %, 120 % and 140 % of the crop water requirement - ETc) based on the evapotranspiration demand. The increase in the irrigation levels could be fit to linear models for the variables number of fruits per plant, mean and total fruit weight per plant, fruit length, and root, stem and total dry weight. Irrigation at 2 p.m. increased the total and mean fruit weight and number of fruits per plant, as well as fruit length, if compared to the irrigation at 8 a.m., besides increasing the yield by 50.82 % (2,343.0 g plant-1 to 3,533.6 g plant-1) and the water-use efficiency by 55.64 %. In areas subjected to water shortages, establishing irrigation times based on irrigation management practices can increase the water-use efficiency and yield for bell peppers.

Published: April 2019

ABSTRACT During the in vitro multiplication of bamboo plantlets, it is common the formation of shoots aggregates. Once individualized, these can yield a greater number of plantlets than if planted in clusters. This study aimed to evaluate the effect of the relationship between height and number of initial shoots in micropropagated bamboo plantlets on the survival and development of plants, during the pre-acclimatization stage. Guadua aff. chaparensis shoots, after successive subcultures of in vitro multiplication, were classified into three height classes (2.5-5.0 cm; 5.1-10.0 cm; 10.1-15.0 cm) and number of aggregate shoots (one shoot per plantlet/single-stem plantlet, two and three shoots per plantlet) and pre-acclimatized in a commercial substrate composition plus washed sand. The plantlets were evaluated for survival, height, number of new shoots and roots, shoot and root fresh and dry mass. In plantlets from micropropagation, the plant height does not influence the survival rates, being acclimatized preferably at heights between 5.0 cm and 15.0 cm, with survival rates of up to 97 %. Plantlets with height starting at 5.1 cm and composed of 2 or 3 initial shoots show a greater vigor and ex vitro growth, a fact evidenced by the higher values obtained in relation to height and emission of new shoots and roots, as well as a greater fresh and dry biomass accumulation.

Published: April 2019

ABSTRACT Bamboo is a versatile plant that is widely used in many areas for feeding, manufacturing of utensils, construction and environmental purposes. The energetic use of bamboo stalks or residues from other applications is a promising alternative and compatible with sustainable development principles. This study aimed to evaluate the potential of four bamboo species (Bambusa vulgaris, Phyllostachys bambusoides, Phyllostachys edulis and Phyllostachys nigra) for briquette production. The following properties were evaluated: moisture content, bulk density, compression strength, proximate analysis, gross calorific value and energetic density. The results showed numbers ranging from 1.109 g cm-3 to 1.228 g cm-3 for bulk density, 4.68 MPa to 5.82 MPa for compression strength, 79.01 % to 82.25 % for volatile content, 15.26 % to 20.18 % for fixed carbon content, 0.38 % to 2.49 % for ash content, 4,571 kcal kg-1 to 4,716 kcal kg-1 for gross calorific value and 5.08 Gcal m-3 to 5.84 Gcal m-3 for energetic density. The briquettes produced from P. nigra presented the best energetic quality, followed by briquettes from P. edulis, P. bambusoides and B. vulgaris. Overall, it may be said that the four bamboo species can be used as alternative raw materials for energy generation.

RESUMO Objetivo Analisar o reconhecimento das figuras e a familiaridade dos contextos do Sentence Production Program for Aphasia (SPPA), para obter dados sobre a possibilidade de uso para a língua portuguesa e/ou da necessidade de sua adaptação. Método Inicialmente, foi realizada a tradução dos estímulos por falantes do inglês e, em seguida, a retrotradução para ajustes sem a alteração das estruturas sintáticas das frases. O material foi então submetido para a análise de 39 indivíduos adultos de alta escolaridade. Na primeira fase do estudo, os adultos deveriam criar uma frase de acordo com cada figura apresentada. Na fase seguinte do estudo, os participantes foram expostos às frases originais associadas aos seus respectivos contextos. Os participantes receberam uma folha de registro das respostas com numeração segundo as figuras e julgaram a familiaridade dos contextos a partir de uma escala analógica de 0 a 10. Resultados Observou-se que a média geral de concordância dos estímulos com as respostas para as figuras do SPPA foi de 35,5%. Em relação à familiaridade dos contextos com as figuras, essa foi maior para as cenas relativas às frases com estrutura sintática mais usadas em português. Conclusão Pelo fato de os estímulos terem apresentado baixo grau de reconhecimento, adaptações serão necessárias para que o programa possa vir a ser utilizado na população brasileira. O estudo também permitiu identificar quais as figuras que necessitam de adaptação antes de serem usadas para a reabilitação de pacientes agramáticos no Brasil.

ABSTRACT: In Brazil, some populations of Conyza bonariensis and C. canadensis are glyphosate resistant and there are populations of C. sumatrensis (Sumatran fleabane) presenting multiple resistance to both glyphosate and chlorimuron. During the 2014/2015 and 2015/2016 seasons, growers reported failures to control Sumatran fleabane with paraquat. This study investigated the potential of paraquat resistant Sumatran fleabane populations in Paraná state, Brazil. Populations with suspected paraquat resistance were tested in the field in 2016 season. In 2017, seeds from these populations were collected, sown and grown in a greenhouse. Paraquat dose-response curve experiments were performed in Mogi Mirim, SP; Londrina, PR and Palotina, PR using doses of 0, 50, 100, 200, 400, 800, 1,600 and 3,200 g ha-1, following all standard criteria for confirmation of weed resistance cases. Percentage control was assessed at 3, 7, 14, 21 and 28 days after application and data were fitted to a nonlinear, log-logistic model, and dose response curves were generated. The results of this study confirmed significant levels of resistance of Sumatran fleabane biotypes to paraquat with resistance factors between 3,57 to 34,29. Therefore, the first case of C. sumatrensis resistance to paraquat was confirmed in biotypes from the western area of Paraná state, Brazil.
Adjuvants to Improve Phenmedipham + Desmedipham + Ethofumesate Efficacy Against Weeds in Sugar Beet (Beta vulgaris)

Published: April 2019

ABSTRACT: The efficacy of reduced (411.5 and 617.2 a.i. ha-1) and recommended (823.0 g a.i. ha-1) rates of phenmedipham + desmedipham + ethofumesate on the control of Amaranthus retroflexus, Amaranthus blitoides, Chenopodium album, and Tribulus terrestris in sugar beet field was investigated when they were tank-mixed with and without Adigor (0.5% v/v), Ammonium sulphate (2% v/v), Citogate (0.2% v/v), D-Octil (0.3% v/v), Hydro-Max (0.5% v/v), and Volck (0.5% v/v). When the herbicide was applied alone, there was no significant difference between the rates of 617.2 and 823.0 g a.i. ha-1 for reduction of total weed density and biomass. Significantly, the adjuvants decreased total weed density and biomass. However, there was no significant difference among the performance of adjuvants. The sugar beet root and sucrose yields were increased significantly by increasing herbicide rate as a result of an improvement in weed control. Although herbicide efficacy was influenced in a similar manner by all the adjuvants, the best results were found as follows: root yield was increased up to 9.66% (71.31 Mg ha-1) by applying the recommended rate of phenmedipham + desmedipham + ethofumesate plus Adigor compared to weed-free check (64.68 Mg ha-1) whereas sucrose yield was increased up to 26.48% (13.21 t ha-1) by applying the recommended rate of phenmedipham + desmedipham + ethofumesate plus HydroMax compared to weed-free check (10.45 t ha-1). From an economic and ecological standpoint, these two adjuvants can be suggested to optimize the recommended rate of phenmedipham + desmedipham + ethofumesate in weed management.

The objective of this work was to evaluate the morphological and metabolic changes of soybean cultivars containing Cultivance® (CV), which is tolerant to imidazolinone, sulphonylurea toletant (STS) and Roundup Ready® (RR), which is tolerant to glyphosate as affected by carryover of increasing doses of imazapyr and imazapic herbicides mixture, applied in the management of irrigated rice crop. Thus, experiments were conducted on the field and in greenhouse, evaluating phytotoxicity, height, leaf area, shoot dry matter, as well as variables related to the secondary metabolism of plants like chlorophyll, carotenoids, hydrogen peroxide, lipid peroxidation and electrolytes leakage. Soybean cultivars RR and STS are susceptibles to the carryover of imazapyr and imazapic mixture applied in the management of irrigated rice crop, whereas the CV cultivar is resistant. The rise in the herbicide carryover dose increases the reactive oxygen species (ROS) production in soybean plants. The RR cultivar, in general, shows higher ROS production compared to the other soybean cultivars.

RESUMO O objetivo deste artigo é contribuir com o debate acerca do desmatamento no contexto da evolução das políticas de gestão fundiária e territorial na Amazônia, destacando seu papel relevante para o reconhecimento de direitos políticos de categorias sociais minoritárias. A associação do desmatamento na Amazônia sempre esteve correlacionada a problemas sociais e envolve diferentes agentes e fatores causadores conforme a área de abrangência e o momento de sua realização. Procuram-se evidenciar alguns dos principais fatores institucionais que contribuem para pôr em xeque as conquistas do modelo socioambiental por meio de um estudo de caso no assentamento rural categoria Projeto Agroextrativista Praialta-Piranheira, Pará. Essa análise permite concluir que a falta de coerência institucional representa um aspecto estrutural cujo desconhecimento incapacita a compreensão das dinâmicas territoriais da Amazônia.

RESUMO O texto discute a cidade em sua condição pós-moderna, entendendo seu corpo material e simbólico a partir do estudo da utopia geradora da cidade moderna do século XX até a construção de novo ideário da cidade contemporânea. Essa trajetória que gerou espaços riquíssimos será a base doutrinária em que urbanistas de todos os matizes gerarão os espaços urbanos do amanhã. A noção de utopia perpassa todo o texto, porque é argumento essencial para a superação dos nossos problemas urbanos atuais.

SUMMARY The use of medicinal plants as a therapeutic method in the control of diseases has been increasing in animal production. In the case of small ruminants, the endoparasitic disease is a major concern, since they are considered the greater sanitary problem, especially when considering the phenomenon of parasite resistance to the medicines used. Therefore, the development of alternative methods of endoparasitary control in goats and sheep has become a pressing need. The use of plants to control endoparasites can reduce the use of chemical inputs, making more environmentally sustainable livestock, minimizing the occurrence of parasitic resistance to conventional medicines and contributing to the reduction of production costs. In this sense, several studies have been carried out in order to evaluate the in vitro and in vivo activity of plants with anthelmintic potential. However, despite the potentiality found in many studies, the results are sometimes contradictory or do not replicate in vivo the same efficacy obtained in the in vitro assays. Another relevant aspect is the low utilization of the lethality and toxicity tests, which are indispensable so that the knowledge can be spread and applied by the producers in their herds. Thus, this review aims to provide the results from studies carried out in Brazil with extract of plants with potential for control of parasitic disease in goats and sheep, describing the main evaluated plants species, mechanisms of action, preparation forms and tests of efficacy, toxicity, and lethality.

Introducción. La organización de los Afros en el municipio de Florencia, representa la necesidad de la unión para lograr un reconocimiento y la lucha por sus derechos; si bien a juicio de los entrevistados la discriminación racial en el departamento, es poca; la necesidad de lograr una visibilización y un reconocimiento, ha hecho que tres organizaciones de Afros se hayan conformado y se sigan consolidando a través del tiempo. El interés del presente manuscrito, es precisamente poder sistematizar estas tres experiencias organizativas a partir de su historia, logros, dificultades y principales retos que enfrentan como colectivo. Metodología. El trabajo es eminentemente cualitativo, la producción de los datos se hizo a partir de instrumentos como las entrevistas y la técnica de arqueo de archivos. Resultados. Dentro de los principales hallazgos se tiene que las organizaciones existentes, son resultado de fragmentaciones internas de la primera, pero que tienen objetivos similares, las mayores dificultades que afrontan están relacionadas con los pocos ingresos para su sostenimiento y poder ayudar más a sus socios. Conclusiones. Los logros de las organizaciones afros han sido el reconocimiento por parte del Ministerio del Interior, el posicionamiento en la sociedad caqueteña y que los hayan hecho partícipes de la toma de decisiones de tipo regional. Las dificultades continúan relacionadas con los pocos recursos económicos disponibles y acceso a proyectos de inclusión socioeconómica rural y urbana, además la falta de articulación interna donde en algunas ocasiones a su juicio prima el bien particular sobre el del grupo. Las tres organizaciones objeto del estudio coincidieron

Introducción: la frecuencia de la hipomineralización incisivo molar es variable, la cual puede estar presente hasta en el 25% de la población. Objetivo: establecer la frecuencia y severidad de HIM en un grupo de niños mexicanos. Materiales y Métodos: el estudio fue de carácter transversal, en el cual se examinó una muestra por conveniencia integrada por 433 escolares entre 8 y 12 años de edad, de ambos sexos. La encuesta consideró la exploración clínica de los primeros molares e incisivos permanentes considerando los criterios establecidos por la Academia Europea de Odontología Pediátrica (EAPD), y para la severidad los criterios de Mathu-Muju y Wright. Para el levantamiento epidemiológico previamente se estandarizó a una examinadora (kappa = 0,93). Resultados: el 13,9% de los escolares presentó HIM, siendo más frecuente en niños (8,1%) en comparación con las niñas (5,8%), asociándose con esta variable (p = 0,049). Por edad, las categorías de 8 y 10 años fueron las que presentaron un mayor número de casos no mostrando relevancia estadística con el evento de estudio. Los primeros molares resultaron estar más involucrados en los patrones de HIM, asimismo, en cuanto a la severidad del HIM la condición leve fue la más frecuente. Conclusiones. La frecuencia y severidad observada muestra un panorama en el cual requiere que se lleve a cabo el seguimiento de los niños con HIM por el riesgo que representan para el establecimiento de caries dental.

Extracción de caninos mandibulares como opcion de tratamiento
Authors: Orrego-Carrillo Herbert Miguel
Published: April 2019

Introducción: la extracción de caninos se indica en casos en los cuales existe impactación de dichas piezas y las posibilidades de tracción ortodóntica son limitadas o nulas. Diagnóstico: se presenta el caso de un paciente de 36 años de edad que acude a consulta por no estar conforme con la estética de su sonrisa. Tratamiento: como alternativa de tratamiento en este caso, se realizaron extracciones de los caninos mandibulares en lugar de los primeros premolares. Discusión: fue posible mejorar las relaciones oclusales, el overjet y el overbite sin perjudicar el aspecto facial del paciente. Siempre que estratégicamente sea conveniente, los resultados funcionales y estéticos obtenidos nos sugieren la posibilidad de tener como opción esta alternativa en el tratamiento de nuestros casos. Conclusión: este esquema de extracciones permite entonces cumplir ambos objetivos: tanto el funcional como el estético; sin embargo, debería reservarse para los casos en los que sea ventajosa su aplicación, hasta que se realicen más pesquisas para garantizar sus efectos a largo plazo.

The aims of this study were to assess children's dental fear by using a projective technique CDFP (Children’s dental fear picture test). 40 patients from a pediatric dental clinic, between 5-9 years old, took part in this study. At first, the CDFP was applied to the children. This method has three subtests and its overall assessment classifies children as "fearful, non fearful and uncertain". The children answered the CFSS-DS (Children Fear Survey Schedule–Dental Subscale). The results showed that CDFP has inter-examiner reliability and a significant correlation with the CFSS-DS was observed.

Introducción: el adecuado diagnóstico de una discrepancia dentoalveolar y un tratamiento realizado tempranamente, son claves para prevenir alteraciones oclusales y oseodentarias que complican los tratamientos futuros en denticiones permanentes. La presente investigación busca determinar la efectividad de las nuevas fórmulas simplificadas para el diseño y evaluación del análisis predictivo en la discrepancia oseodentaria en dentición mixta en niños de 7 a 10 años atendidos en la Fundación Hospital Metropolitano de Barranquilla. Metodología: estudio descriptivo correlacional en modelos de estudios de niños de 7 a 10 años, que asistieron a la Fundación Hospital Universidad Metropolitana de Barranquilla entre el año 2012-2013. El muestreo fue probabilístico aleatorio, luego de calcular el tamaño de la muestra con un 95% de confianza y un margen de error del 5% se obtuvo una muestra de 119 niños. Se llevó cabo una prueba piloto con el 27% del total de la población con el fin de realizar ajustes pertinentes. Resultados: Las discrepancias obtenidas en los resultados de las fórmulas simplificadas, arrojaron resultados significativamente similares a los valores obtenidos con Moyers dando así un diagnóstico certero de las mal oclusiones. Las medidas del tamaño de los caninos y las mediciones del espacio requerido para la erupción de los premolares, fueron similares en cuanto a promedio y desviación estándar Conclusión: Las ecuaciones producto de esta investigación, se usarán como herramienta para el análisis de predicción en dentición mixta en la población Colombiana distrito de Barranquilla
