Features of chronic heart failure depending on the left ventricular ejection fraction
Authors: Dushina A. G. , Lopina E. A. , Libis R. A.
Published: March 2019

Aim.To assess clinical and demographic data, structural and functional features of the myocardium in patients with chronic heart failure (CHF) with a preserved ejection fraction in comparison with patients with CHF with an intermediate (CHF-inEF) and a reduced ejection fraction (CHF-rEF).

Material and methods. The study included 186 patients with CHF I-IIB stages, I-III functional classes. One hundred and three patients had a preserved ejection fraction (EF) (≥50%), 43 — intermediate (40-49%) and 40 — reduced (<40%). All patients underwent a comprehensive clinical examination, as well as standard echocardiography.

Results.Among patients with CHF-rEF, remodeling of the left ventricular myocardium by the type of concentric hypertrophy was more often observed (69,9%), and among CHF-inEF and CHF-nEF patients — by the type of eccentric hypertrophy (88,4 and 875%, respectively). Restrictive diastolic dysfunction was observed in 2,0% of patients with CHF-rEF and in 21,7% of patients with EF less than 50%.

Conclusion.The severity of the clinical course of CHF does not depend on the left ventricular EF. Epidemiology and etiology of CHF-rEF has fundamental differences from CHF-inEF and CHF-nEF: CHF-rEF is more common among women over 60 years old with arterial hypertension and obesity. For patients with CHF-inFV, myocardial remodeling by the type of concentric hypertrophy and the prevalence of non-restrictive types of diastolic dysfunction are characteristic.

Authors: Marenco Ricardo Antonio , Sousa Francinete de Freitas , Oliveira Marcilia Freitas de
Published: March 2019

ABSTRACT Munguba (Pseudobombax munguba) is a tree often found in low-land forests of the Amazon region, and there is a paucity of data regarding its ecophysiology. The aim of this work was to determine photosynthetic rates and growth of munguba saplings and to describe leaf phenology of a munguba tree. In greenhouse-grown saplings, diameter growth, leaf expansion, photosynthesis and stomatal conductance were determined. To describe the relationship between photosynthesis and leaf expansion, regression analysis was used. It was also described the leaf phenology of an adult tree by observing foliage changes at one-week intervals for two years. The leaves completed their expansion in 18 days, and leaf greening was completed in 40 days. Photosynthesis positively correlated with leaf expansion, but there was no correlation between stomatal conductance and leaf growth. Growth in diameter was 1.8 mm month‒1. Relative growth rate was low, 0.010 g g-1 day-1. In the adult tree, leaf shedding was concentrated in July-August and by the second week of September the tree had already produced new leaves. Leaf longevity of munguba is about 11 months. It is hypothesized that leaf phenology of munguba is associated with the increased solar radiation of the dry season.

RESUMEN La enfermedad mildeo velloso en mora de castilla es causada por patógenos pertenecientes al género Peronospora, el cual genera graves pérdidas en periodos cortos y afecta principalmente hojas, tallos y frutos; además, la presencia de agentes infecciosos ocasiona estrés en las plantas, activando la síntesis de metabolitos secundarios como mecanismo de defensa. El objetivo del estudio fue establecer la identidad taxonómica de la especie Peronospora causante de la enfermedad mildeo velloso en mora de castilla (Rubus glaucus Benth) cultivados en la región andina de Colombia y determinar su efecto en el contenido de fenoles totales en los frutos. La investigación se llevó a cabo en los municipios de Santuario y Santa Rosa de Cabal, departamento de Risaralda, Colombia, entre los meses de febrero y mayo del año 2017. Se seleccionaron y analizaron dos cultivos por cada municipio. Se realizó la identificación taxonómica del hongo Peronospora sp., mediante la amplificación por reacción en cadena de la polimerasa (PCR) y la evaluación del contenido de fenoles totales, por el método de Folin-Ciocalteu. La especie Peronospora sparsa fue la causante de la enfermedad en mora de castilla en el departamento de Risaralda. Además, se encontraron diferencias significativas en el contenido de fenoles totales en el material evaluado (p < 0.05). La presencia del hongo P. sparsa en frutos de R. glaucus produjo un incremento en el contenido de compuestos fenólicos, pasando de 7.75 ± 0.71 mg g-1 de AGE con base húmeda en los frutos sanos, a un valor de 14.70 ± 1.11 mg g-1 de AGE con base húmeda para los frutos afectados.

ABSTRACT This study aimed to evaluate production components of sunflower (Helianthus annuus L.) plants irrigated with domestic wastewaters treated by different processes, with two irrigation depths. The experiment was carried out in Ibimirim, state of Pernambuco, Brazil, using a randomized block design in a 4×2 factorial arrangement, with four replications. The treatments consisted of four irrigation water types (domestic wastewater treated by UASB reactor - DW1; domestic wastewater treated by digestion decanter and anaerobic filtration - DW2; domestic wastewater treated by anaerobic filtration - DW3; and public water - PW4) and two irrigation depths (equal to the crop evapotranspiration - ID1; and 20% higher than the crop evapotranspiration - ID2). The production components-plant fresh and dry weights, 1000-achene weight, capitulum internal diameter, achene yield, oil content, and oil yield-were evaluated at the end of the crop cycle. The irrigation with treated domestic wastewater improved all variables analyzed when compared to the drinking water, especially when using DW2 and DW3 with ID1.

RESUMO A goiabeira é uma frutífera cultivada mundialmente, destacando-se pela grande aceitação no mercado consumidor. Entretanto, para que a cultura explore o seu máximo potencial produtivo e mantenha a qualidade dos frutos, é necessária a adequada adubação mineral para elevar a disponibilidade de nutrientes no solo e aumentar sua absorção pelas plantas. Objetivou-se, com este trabalho, avaliar os efeitos da adubação com doses de potássio, na presença e na ausência de cálcio, no estado nutricional e na produção da goiabeira 'Paluma'. O experimento foi desenvolvido de agosto de 2015 a maio de 2016, no município de Remígio, Paraíba. As variáveis analisadas foram: teores foliares de macro e de micronutrientes, número de frutos por planta, massa média de frutos, produção de frutos por planta e produtividade. As plantas da goiabeira estavam adequadamente supridas em nitrogênio, fósforo, potássio, cálcio, magnésio, boro, ferro, manganês e deficientes em enxofre, cobre e zinco. A adubação com cálcio incrementou os teores foliares de P, K, Ca, S, B, Mn e Zn e reduziu o número de frutos por planta e a produtividade da goiabeira 'Paluma'. A adubação potássica sem adição de cálcio, nas doses entre 101 e 143 g planta-1 ano-1 de K2O, aos 16 meses de idade, proporcionou a maior produtividade da goiabeira 'Paluma'.

Published: March 2019

ABSTRACT Liming acid soils is fundamental for agricultural activity such as the study and characterization of alternative liming material. The objective of this study was to characterize biological, sedimentary, and metamorphic limestones. The following limestones were studied: biogenic (BL), sedimentary (SL), commercial (CL), and marble (ML). This study evaluated total relative neutralizing power (TRNP), chemical composition, specific surface area, and Ca2+and Mg2+release at concentrations of 0.10, 0.50, 1.00, and 2.00 mol L-1 HCl, in addition to the effects on the soil 90 days after limestone application. The Si identified contributed to the lower TRNP of BL (73.7%) and CL (74.4%). At the lowest HCl concentrations, BL was the most reactive, but with an increase in concentration, ML became the most reactive. The highest CaO (58.32%) and MgO (13.05%) levels were observed in SL and ML, respectively, which contained the highest Ca2+(3.95 cmolcdm-3) and Mg2+ (1.09 cmolcdm-3) concentrations when applied to the soil. All the limestones increased pH and lowered soil H+Al. Soil Ca2+and Mg2+were influenced by the composition of the amendments.

Developmental health in the context of an early childhood program in Brazil: the “Primeira Infância Melhor” experience
Authors: Gonçalves Tonantzin Ribeiro , Duku Eric , Janus Magdalena
Published: March 2019

Design and evaluation of early child development (ECD) programs are poorly documented in low- or middle-income countries. The study aimed to identify family and child characteristics associated with developmental health outcomes among children aged from 4 to 6 years who participated in the “Primeira Infância Melhor” - PIM (Better Early Childhood), a home visiting program in Rio Grande do Sul State, Brazil. We also evaluated the impact of PIM on developmental vulnerability at school entry using a comparison group. Multistage sampling was first used to select cities, then families, in different regions of the state, resulting in a sample of eight cities and 571 children (364 PIM; 207 comparison). We used a sociodemographic questionnaire, completed by parents, and the Early Development Instrument (EDI), completed by teachers. Among PIM children, lower family income, time of exit from the program, city, and younger age were associated with higher risk of developmental vulnerability and/or with lower mean scores in EDI domains. Multivariate analysis controlling for covariates found no differences between the study groups in EDI outcomes even though the gaps in equity of the outcomes were smaller in the PIM group. These results are discussed in the context of challenges faced by home visiting programs in addressing complex social conditions of high-risk families and difficulties in finding an adequate comparison group in communities where an ECD program is universally accessible. We also note the importance of setting structured and longitudinal monitoring systems together with the implementation of ECD policies.

Abstract The aim of this study was to evaluate whether amplifying the volume and/or time of contact of NaOCl affects the fracture strength of endodontically treated bovine teeth. Four bovine incisors from 10 animals were allocated into 4 groups using a split-mouth design. Root canals were instrumented using a sequence of 4 manual stainless steel files and irrigated with a 5.25% alkalized NaOCl solution. The total volume and time of irrigation, per sample, varied among the groups as following: standard volume and time of contact - 15 mL/11.5 min; volume raise - 30 mL/11.5 min; time of contact raise - 15 mL/19 min; and volume and time of contact raise - 30 mL/19 min. Samples were subjected to a fracture resistance assay. At p=0.05, two-way ANOVA statistically scrutinized the results. Effect size of NaOCl time of contact and volume were also calculated (η2). The variation in time (p=0.000), volume of irrigation (p=0.000) and the combination of both (p=0.038) negatively influenced the fracture resistance. Standard volume and time of irrigation showed the highest fracture strength while isolated increase in volume or time reduced in 25% and 37%, respectively, the fracture resistance; the simultaneous increase in volume and time of irrigation promoted a reduction of 47%. Effect size of NaOCl time of contact was superior (0.746) than the volume (0.564). Raising the volume and/or time of a 5.25% alkalized NaOCl solution reduces the fracture resistance of endodontically treated bovine teeth.

Published: March 2019

Abstract Maltodextrins, derived from corn starch, have been added to industrialized food combined with sucrose. However it is not clear the diffusion properties of the dental biofilm matrix and the tridimensional structure of multispecies biofilms formed in the presence of these carbohydrates. Therefore, the aim of study was to investigate by confocal laser scanning microscopy (CLSM) the structural organization of the multispecies dental biofilm formed in situ under exposure to sucrose associated to maltodextrin. Adult volunteers wore an intraoral palatal appliance containing bovine enamel blocks. They were instructed to remove the appliance 8 times per day and drop the following solutions on the enamel blocks: deionized distilled water (DDW), maltodextrin, sucrose + maltodextrin or sucrose. Biofilms formed were stained and the percentage of extracellular polysaccharide (%EPS) and thickness were determined by CLSM. Biofilm formed in the presence of sucrose and sucrose + maltodextrin presented similar %EPS and higher than DDW and maltodextrin. Regarding to the biofilm thickness, sucrose and sucrose + maltodextrin treatments were thicker than DDW and maltodextrin and similar between them. The structural organization of the multispecies dental biofilm formed in situ in the presence of sucrose does not change when this carbohydrate is associated to maltodextrin.

Abstract The purpose of thisin vitrostudy was to evaluate the influence of a new proposal of implant design and surgical protocol on primary stability in different bone densities. Four groups were tested (n=9): G1 - tapered, cone morse, Ø 4.3 mm x 10 mm in length (Alvim CM); G2 - experimental tapered; G3 - cylindrical, cone morse, Ø 4.0 mm x 11 mm in length (Titamax CM) and G4 - experimental cylindrical. The experimental implants were obtained from a design change in the respective commercial models. The insertion was performed in polyurethane (PU) blocks 0.24 g/cm3(20 pcf) and 0.64 g/cm3(40 pcf), according to different surgical protocols. The primary stability was measured by means of insertion torque (IT) and pullout test. Data were analyzed by ANOVA, Tukey’s test (α=0.05) and Pearson’s correlation. For IT and pullout, conventional and experimental implants showed no difference between them when inserted in the 20 pcf PU (p>0.05). In the 40 pcf PU, the modified implants exhibited greater IT (p<0.05) and lower pullout (p<0.05) compared to the respective conventional models. The implant design tested associated with the surgical protocol, positively influenced primary stability in higher density bones.
Phosphorus requirement and partitioning in oat cultivars

Published: March 2019

ABSTRACT: Maintenance fertilization changes with nutrient requirements and partitioning, but these are not well known for oat cultivars. The aim of this study was to evaluate whether phosphorus (P) requirements and partitioning vary among cultivars of oat (Avena sativa L.). The UPFA ‘Ouro’, UPFPS ‘Farroupilha’, IPR ‘Afrodite’, URS ‘FAPA Slava’, ‘Barbarasul’, ‘FAEM 007’, URS ‘Taura’, and ‘URS 21’ were cultivated in a Latosol with high P content in a greenhouse in 2015. Plants were sampled at physiological maturity and divided into roots, stem, leaves, and grain tissues. Phosphorus content and the dry matter weight of these parts were evaluated and the uptake amount and partitioning of P were estimated. The values of these variables differed across cultivars, except the P content in the grain (‘average’, 4.0g P kg-1). ‘Afrodite’ and ‘FAPA Slava’ have lower requirements and partitioning of P in the grain, but these did not vary among the other cultivars. Requirements and partitioning of P in stem and leaves increased in the following order: ‘Ouro’ and ‘Farroupilha’<‘Taura’ and ‘FAPA Slava’<‘URS 21’<‘Afrodite’, ‘Barbarasul’ and ‘FAEM 007’. Requirement and partitioning of P in roots, stem, leaves, and grain differs across cultivars, which indicates that this factor, besides how the oat is used (such as for grain, pasture, silage, cover crop), can be used to improve maintenance fertilization.

ABSTRACT: The objective of this study was to evaluate the plant and fruit characteristics in advanced lines of Jalapeño pepper for mechanical harvesting. Thus, two experiments were carried out in the field. Experiment I (2015) was conducted as a randomized block design (three replications and eight plants per plot) and Experiment II (2016) in a completely randomized design (five replications and ten plants per plot). In 2015, lines CNPH 30,112, CNPH 30,118, CNPH 30,147, CNPH 30,159, CNPH 30,183, and CNPH 30,245 were evaluated, together with the control ‘BRS Sarakura’. Significant differences were detected for fruit and plant characteristics (P<0.05). Lines CNPH 30,118, CNPH 30,147, CNPH 30,159, and CNPH 30,245 were selected based on plant height and height of the first bifurcation, earliness, and yield. They were evaluated again in 2016, together with ‘BRS Sarakura’ and ‘Jalapeño Plus F1’ as controls. In 2016, CNPH 30,159 and CNPH 30,118 were selected due to their potential for mechanical harvesting. They were evaluated for height of the first bifurcation (>10cm), large fruits (11 cm x 4 cm), high pulp firmness (11 N), wall thickness (about 5mm), and content of capsaicinoid substances (>50,000 SHU). Selected lines are undergoing additional field evaluation for mechanical harvesting with the Etgar Moses 1010 pepper harvester.

ABSTRACT: Pythiosis in felines is a rare disease associated with the oomycete Pythium insidiosum. The aim of this report was to describe the macroscopic, histopathological, and molecular characteristics of P. insidiosum infection in a 2-year-old cat, with a localized invasive subcutaneous mass. The feline had an increase of volume near the anal region since it was younger. The cat died just after surgery. The necropsy was performed, and samples were collected for histopathological examination. Microscopically, the skin lesion was characterized by necro-eosinophilic dermatitis, panniculitis, and myositis surrounding negatively stained hyphal structures. In the sections stained with GMS, dark brown hyphae were clearly seen inside the affected tissue. They were rarely septate and their walls were almost parallel. Immunohistochemistry using a polyclonal anti-P. insidiosum antibody showed a strongly immunostained hyphae into the lesions. The analysis based on PCR had a positive result for P. insidiosum. Pythiosis should be considered in the differential diagnosis of subcutaneous tissue disorders in felines.

ABSTRACT: In Brazil, at least 30% of the total financial resources provided by the federal government for school feeding should be used to buy products from family farming. The present study examines the profile of the purchase of these products in municipalities of the state of Rio Grande do Sul (RS), south Brazil, in 2014. A cross-sectional descriptive study was carried out with information obtained through a questionnaire sent to the municipalities and filled by respondents. Of the 371 participating municipalities, 367 acquired products from family farming, and 86.8% of these municipalities achieved the minimum percentage required. Nutritionists and farmers were the main components involved in the articulation of this process. Difficulties faced by these individuals included the lack of organization of the producers, failure to meet the demand, and lack of interest. More than 80% of the municipalities bought food from the “Vegetables”, “Cereals, Breads, Pasta, and Tubers” and “Fruits” groups. Only 8% purchased products from socio-biodiversity. There was a great diversity of food purchased, most of which were in natura, despite the low acquisition of socio-biodiversity products. Results of this study indicated the concern and tendency of the Brazilian municipalities to support the local economy with incentives to consumption and production of regional foods.

Resumo A Física estuda fenômenos da natureza e que comumente podem ser observados no cotidiano. O trânsito é uma dessas situações, e acredita-se que uma aproximação entre os conceitos físicos e situações aplicadas no cotidiano do trânsito pode possibilitar ao estudante melhores compreensões da Física do Ensino Médio e acima de tudo, que esses conhecimentos possam ser utilizados durante a vida do indivíduo. Porém, verificar se os egressos da escola estabelecem relações entre conteúdos de Física com fenômenos observados no trânsito ainda é um grande campo de estudo. O presente artigo apresenta o trabalho de validação de um questionário elaborado para uma pesquisa de mestrado. Para tal, a validade de conteúdo foi realizada através de juízes especialistas da área; calculamos a consistência interna através do coeficiente Alfa de Cronbach, obtendo valor de 0,74, assim como utilizou-se o Teste U de Mann-Whitney para observar se havia diferenças entre as médias de acertos dos dois grupos estudados. Os resultados atestam que o instrumento possui validade para os objetivos da pesquisa, consistindo de um teste para verificar a retenção conceitual de assuntos de Física em egressos do Ensino Médio.

Published: March 2019

ABSTRACT The Penman-Monteith method (PM-FAO) is recommended as standard for calculation of reference evapotranspiration (ETo). However, its use requires a series of meteorological variables that is not normally available, restricting its application in many locations. A solution to the problem of unavailability of meteorological data was presented in FAO Bulletin 56, which contains methodologies for estimating wind speed, solar radiation and relative humidity. The objective of the present study was to evaluate the performance of the PM-FAO methodologies for missing data and Hargreaves-Samani as alternatives to the PM-FAO standard method at different time scales and seasons for the municipalities of Linhares and São Mateus, located in the northern region of the state of Espírito Santo. The comparison was performed using linear regression parameters (β0 and β1), coefficient of determination, standard error of estimation (SEE) and coefficient of performance. The best alternative to the standard PM-FAO standard method for estimating ETo in the studied area was the Penman-Monteith method with missing wind speed data, since the R2 for this method always remained above 0.94 and the confidence coefficient was classified as great, for all seasons and scales. The Hargreaves-Samani method did not present satisfactory performance, with R2 below 0.7, regardless of the time scale and time of the year, and it yielded the greatest SEE (1.0 mm d-1) at spring on a two-day scale. Thus, its use in the northern region of the Espírito Santo state is not recommended.

ABSTRACT The plant Varronia leucocephala is widely used in Brazil for its therapeutic properties. However, a major problem for the seedlings is the low percentage of root formation. The objective of this study was to establish a rooting protocol for V. leucocephala cuttings, using phytoregulators and microelements associated with arbuscular mycorrhizal fungi. The auxin indole-3-butyric acid (IBA) concentration of 1500 mg L-1 showed the best rooting percentage, and it is proposed associating the microelements zinc and boron with the highest IBA doses. Although an increase in the rooting percentage was observed in the presence of zinc, it was not the most suitable for improving the percentage of propagation. Consequently, association of arbuscular mycorrhizal fungi with 1500 mg L-1 IBA plus zinc was selected to evaluate the rooting percentage and sprouting of the aerial part, dry biomass of roots and aerial part, number of leaves, height, mycorrhizal colonization and dependency, spore density, and nutrients of branches and roots. These results show that using zinc with the highest doses of IBA (1500 mg L-1) in plants inoculated with the arbuscular mycorrhizal fungus (Gigaspora albida) was the most effective at promoting the vegetative propagation of V. leucocephala.

ABSTRACT The objective of this study was to evaluate the effect of Ca and Mg silicate and B on the gas exchange, leaf water potential and chlorophyll fluorescence parameters in the sunflower variety Embrapa 122 -V2000 under water stress conditions. The trial was conducted in Red Yellow Latosol with very clayey texture, with contrasting levels of Si and B and subjected to water deficit. The experimental design was randomized blocks in a 24 factorial arrangement, with five replicates. Treatments consisted of the combination of two acidity corrective agents (calcium magnesium silicate and dolomitic limestone), two levels of base saturation (30 and 70%), two levels of B (0.18 mg dm-3 - value available in the soil and 1.20 mg dm-3) and two water regimes (with and without water stress from the beginning of flowering). It can be concluded that the supply of Si and B can reduce the damage to sunflower caused by water stress.

ABSTRACT Grain sampling requires the use of appropriate and accurate equipment. This study aimed to compare grain samplers, manual and mechanical, used in the sampling of soybean loads, during their reception by storage units. The used devices were the manual sampler with 1.80 m length and three opening stages, 2.10 m length and three opening stages; and 2.10 m length and one opening stage, besides the mechanical sampler (pneumatic) and the pelican sampler. The analyzed parameters were the contents of impurity, broken grains, pods, immature grains, and moisture. The significance of effect of treatment was determined by F Test and the means were compared by Tukey test (p < 0.05). The devices used for sampling of soybean grains in vehicles, during their reception by storage units, affect the determination of broken grains, pods and immature grains. However, there was no difference between the types of sampling equipment in the determination of impurity content, and the pelican sampler collected greater percentages of pods and immature grains from the sampled vehicles.

Published: March 2019

ABSTRACT This study evaluated historic land use and land cover changes in the Arroio Marrecas watershed (Caxias do Sul, Rio Grande do Sul state of Brazil) and simulated future land use scenarios until 2034. Spatial and temporal simulations were conducted with the Conversion of Land Use and its Effects - Small Regional Extent (CLUE-S) model. Three land use scenarios were developed to include public policies and agricultural trends in the study region for 20 years (2015-2034). Geospatial analysis of different land uses showed that areas that were originally covered grasslands and forests decreased, which can be attributed to the expansion of intensive agricultural uses, such as fruit farming/forestry and urbanization. The reallocation dynamics of land use with CLUE-S was primarily driven by the soil class (especially Typic and Humic Dystrudepts and Lithic Undorthents), with limited effects of altitude and slope. Analysis of the land use maps of the Arroio Marrecas watershed until 2015 identified major human-induced changes that were driven by expanding agricultural production and urbanization. The allocation of land use derived from the proposed future scenarios with CLUE-S showed that in this regional context, Humic Dystrudepts and Rhodic Kanhapludults were the key drivers of the allocation of agricultural expansion. Conversely, natural resource conservation was indicated to most likely occur in Typic Dystrudepts. The main limitation of this approach is the recognition of driving factors that have a high correlation with each land use as effective predictor variables.

Resumo Introdução Os adesivos autocondicionantes apresentam técnica adesiva simplificada e diminuição na sensibilidade pós-operatória. Quando aplicados sobre a dentina, atuam sobre a smear layer, cuja efetiva remoção ainda constitui um desafio. Uma substância utilizada como pré-tratamento dentinário na ajuda da remoção da smear layer é o etilenodiamino tetracético dissódico (EDTA). Objetivo Avaliar os efeitos do EDTA em associação com sistemas adesivos autocondicionantes na resistência de união ao microcisalhamento. Material e método Foram seccionadas as superfícies oclusais de 72 terceiros molares humanos extraídos, para expor superfície dentinária plana. Os dentes preparados foram divididos em: dentina sem pré-tratamento; dentina tratada com EDTA 0,1M; dentina tratada com EDTA 0,5M. Cada grupo recebeu tratamento de três sistemas adesivos autocondicionantes: Single Bond Universal (SBU), AdheSE (AdheSE) e Clearfil SE Bond (CSEB). Foi delimitada a área adesiva e assim posicionada uma matriz transparente, para inserção com resina composta Z250XT seguida de polimerização por 40 segundos. Após 24 horas de armazenamento, os dentes foram submetidos ao ensaio de microcisalhamento. Os dados obtidos foram analisados estatisticamente, utilizando-se os testes Two-Way ANOVA e Bonferroni, e sendo considerado nível de significância de 5%. Resultado Não houve diferença estatística significante na resistência de união entre os pré-tratamentos dentinários (p=0,8353), porém houve diferença significativa entre os adesivos (p<0,05) CSEB e AdheSE, mostrando semelhança entre CSEB e SBU, e entre SBU e AdheSE. Conclusão O pré-tratamento dentinário com solução de EDTA não afetou a resistência de união com nenhum dos sistemas adesivos autocondicionantes utilizados.

Abstract Objective: to analyze the sexual behavior of the elderly women treated at the gynecological outpatient clinic over a period of one year, estimating the proportion of sexually active women, those with an interest in sex, and those who considered the activity of sex important for quality of life, among other findings. Method: a cross-sectional, descriptive, and exploratory study was performed. A pilot study was carried out in order to adjust and validate the data collection instrument. A convenience sample of 100 women was considered for the evaluation of socio-demographic characteristics and sexual behavior, including questions relating to sexual practice and interfering factors. The data were analyzed using frequencies and percentages, and the associations were verified by Pearson’s Chi-squared test, considering a significance of 5%. Results: it was observed that 60.0% of the elderly women felt sexual desire, although 26.0% were sexually active. While 75.5% reported that aging does not improve the quality of sex, 83.0% believed that it is important for quality of life and 78.0% affirmed that there is no age limit for sexual activity. The cultural view of the elderly may interfere with the maintenance of a sexual life, since 51.0% reported feeling sexual prejudice due to their age. Conclusion: sexuality is directly related to the perception of quality of life and as it is a vital human function, can interfere in the social, professional, physical and psychic performance of the individual. The practice of and the desire for sex are not extinguished with aging, which contradicts the myth that the elderly person is an asexual being.

Abstract Objective: to determine the dietary patterns of elderly persons in terms of sociodemographic, lifestyle and clinical aspects. Method: a cross-sectional study was conducted using the cohorts of the SABE (Health, Wellbeing and Aging) study. An epidemiological, home-based study representative of the city of São Paulo was carried out. The population of this study included 1,304 elderly persons (≥60 years), of both genders, selected by probabilistic stratified sampling, interviewed in 2010. Food intake data were obtained through a qualitative food frequency questionnaire. Dietary patterns were determined by exploratory factorial analysis by principal components. The Wald test was used for complex sampling. Results: four dietary patterns were identified: inadequate patterns, consisting of fried and canned food, sausages, sweets, tubers, industrialized sauces and eggs; modified pattern, skimmed milk, whole grain breads and cereals, light/diet/zero foods; beneficial pattern, fruits, vegetables and tubers; and traditional Brazilian pattern, vegetable oils, rice, refined cereals and white bread, meats and legumes (beans). The sociodemographic and lifestyle profile of the elderly persons who adopted each dietary pattern was different. Conclusion: healthier dietary patterns were associated with the female gender, older elderly persons, two or more chronic diseases, higher levels of schooling, a better lifestyle and a better self-perception of health. It is important to consider all these aspects as they are determinant in the type of diet adopted by this population.

Abstract Objective : to analyze measures of social support and cognitive processing among elderly caregivers and non-caregivers. Method : a comparative, cross-sectional and quantitative study was performed. Participants were divided into two groups: 41 elderly caregivers of other elderly persons (G1) and 41 elderly non-caregivers (G2). Sociodemographic, health and care variables, social support, cognition and cognitive processing (verified by long-latency auditory evoked potential acquisition with the Neuron-Spectrun-4 / EPM device) were assessed. Results : in G1, the majority were female (n=33, 80.5%), married (n=34, 82.9%), with a mean age of 68.5 (± 5.8) years, a mean 4.5 (± 3.7) years of schooling and had provided care on average for 18.0 (± 18.4) years for 6.5 (± 5.1) hours per day. In G2, the majority were female (n=31, 75.6%), widowed (n=23, 56.1%), had a mean age of 69.8 (± 7.2) years and a mean 3.7 (± 2) years of schooling. There were no statistically significant differences between the groups in social support, cognition and cognitive processing. Conclusion : the task of caring did not have a negative influence on social support and cognitive processing. This research may contribute to the planning of actions among primary health care providers and to future research investigating other factors that permeate this relationship.

Abstract Objectives : to identify the perceptions of family caregivers regarding the changes that occurred in the family after an elderly relative received a diagnosis of dementia, measuring the changes in the level of burden and analyzing the discourse of such caregivers. Method : the research was conducted through an interview and sociodemographic questionnaire, in addition to the application of a scale that measures caregiver burden, the Zarit Burden Interview. These procedures were applied in two stages, in the multidisciplinary reception of a geriatric clinic, and after three months of care. For the qualitative analysis, the IRaMuTeQ software was used, where, in the first stage, the results were as follows: in the Descending Hierarchical Classification (DHC) four classes were identified: Time (25.00%), Knowledge (33.00%), Consequences and Causes (19.40%); In the Word Cloud (WC), the word ‘No” prevailed. In the second stage, DHC presented six classes, Current Time (13.70%), General Causes (15.70%), Future Time (13.70%), Actions (17.60%), Consequences (23.50%) and Immediate Causes (15.70%). The WC continued to refer most frequently to the word ‘No’. For quantitative analyzes, the SPSS software was used. Results : in most cases, the profile of caregivers was women (75.00%), wives (62.00%), primary caregivers (87.50%), and the elderly (60-75 years). The assessment of burden was moderate to severe (75.00%). Conclusion : caring for a relative with a diagnosis of dementia has direct implications for family caregivers, especially family caregivers facing the aging process. The demands of caring modify the family routine and greatly increase the burden of caregivers.
