Impacto do padrão geométrico ventricular na remodelação cardíaca após o infarto do miocárdio

BACKGROUND: The relevance of left ventricular (LV) geometric pattern after myocardial infarction is not known. OBJECTIVES: To analyze the presence of different LV geometric patterns and teir impact as a predictor of remodeling in patients with myocardial infarction. METHODS: Patients with anterior acute myocardial infarction (n = 80) were divided according to the geometric pattern: normal (normal left ventricular mass index [LVMI] and normal relative wall thickness [RWT]), concentric remodeling (normal LVMI and increased RWT), concentric hypertrophy (increased LVMI and RWT) and eccentric hypertrophy (increased LVMI and normal RWT). After six months, echocardiographic assessment was repeated. RESULTS: Four patients died. Of the survivors, 41 showed remodeling (R +), whereas 39 did not (R-). Considering the geometric pattern, the cases were distributed as follows: 24 patients with normal pattern, 13 with concentric remodeling, 29 with concentric hypertrophy and 14 with eccentric hypertrophy. Patients who showed remodeling had larger infarction sizes analyzed by peak CPK (R + = 4,610 (1,688-7,970), R- = 1,442 (775-4247), p <0.001) and CK-MB (R + = 441 (246 - 666), R- = 183 (101-465), p <0.001), trend towards higher prevalence of concentric remodeling (R+ = 10, R- = 3, p = 0.08) and lower prevalence of eccentric hypertrophy (R + = 2 R- = 12, p = 0.006). In the multivariate regression analysis, infarction size was a predictor (OR = 1.01, p = 0.020) and eccentric hypertrophy was a protective factor (OR = 0.189, p = 0.046) of ventricular remodeling after coronary occlusion. CONCLUSION: The LV geometric pattern of can have an impact on the remodeling process in patients with myocardial infarction.

Geoestatística na avaliação dos atributos físicos em latossolo sob floresta nativa e pastagem na Região de Manicoré, Amazonas

The use of geostatistical techniques allows detection of the existence of dependence and the spatial distribution of soil properties, thus constituting an important tool in the analysis and detailed description of the behavior of soil physical properties. The aim of the present study was to use geostatistics in assessment of physical properties in a Latossolo (Oxisol) dystrophic under native forest and pasture in the Amazon region of Manicore. Grids with of 70 x 70 m were established in native forest and pasture, and points were marked in these grids spaced at every 10 m, for a total of 64 points. These points were then georeferenced and in each one, soil samples (128) were collected at the depths of 0.00-0.20 and 0.40-0.60 m for a survey of their physical properties. These grids are parallel at a distance of 100 m from one another. The following determinations were made: texture, bulk density and particle density, macroporosity, microporosity, total porosity and aggregate stability in water. After tabulating the data, descriptive statistical analysis and geostatistical analysis were performed. The pasture had a slight variation in its physical properties in relation to native forest, with a high coefficient of variation and weak spatial dependence. The scaled semivariograms were able to satisfactorily reproduce the spatial behavior of the properties in the same pattern as the individual semivariograms, and the use of the parameter range of the semivariogram was efficient for determining the optimal sampling density for the environments under study. The geostatistical results indicate that the removal of native forest for establishing pasture altered the natural variability of the physical properties.

Testes tonais de padrão de frequência e duração no Brasil: revisão de literatura

Este estudo tem como tema o teste de padrão de frequência e de duração no Brasil e como objetivo revisar e explanar sobre a avaliação do processamento auditivo temporal no Brasil, mais especificamente sobre os testes tonais de ordenação temporal (teste de padrão de frequência e duração). Para atingir tal objetivo foi realizado um trabalho de revisão sistemática da literatura em periódicos nacionais, acessados eletronicamente na base de dado Scielo e Lilacs, sem restrição ao ano de publicação. A pesquisa foi estruturada por meio dos descritores: processamento temporal, processamento auditivo temporal, testes temporais, testes tonais de padrão de frequência e testes tonais de padrão de duração, percepção auditiva e testes auditivos. A pesquisa retornou 33 publicações nacionais sendo 28 artigos de periódicos, uma dissertação de mestrado e quatro teses de doutorado. Com isso, pode-se perceber que a utilização de testes que avaliem a habilidade de ordenação temporal no Brasil é recente, sendo notável o aumento significante das publicações nos últimos cinco anos. Desta forma, o emergente conhecimento possibilitado pelo acesso aos testes no Brasil permite ampliar um campo de pesquisa a todos os profissionais comprometidos com este tema.

Estudo comparativo da textura superficial entre os materiais estéticos indiretos

The purpose of this study was to evaluate surface rugosity among indirect esthetic materials (Vita VMK 95, Solidex, Artglass, Targis). Ten samples of each material in the cilindric shape with dimension 6 x 6 mm were manufactured. The surface were submitted to finishing and polishing, according to manufacturer's recommendations. The samples were submitted to measuremenst, using the Hommel Tester T500 device. The average values of maxim surface rugosity among the materiais ín question, were 5, 73pm; 5, 15pm; 6, 83 j.Jm e 3, 72 j.Jm, respectively. Sample were also subjectted to variance analysis- ANOVA (5%), had detected significance. Concluded that the material Solidex did not present significant statistical differences among groups, while Targis presented significant statistical differences in relation to the Artglass and the ceramic Vita vmk95.

Estudo comparativo de dois programas de computador (Dolphin Imaging e Nemotec) versus o método manual utilizados para análises cefalométricas de pacientes com deformidade dento-facial padrão II

A-Nperp, Pg-Nperp e mandibular plane). Thirty patients (male or female), with age varying from 19 to 48 years old were analyzed. All patients were diagnosted with mandibular retrognathism and submitted to bilateral sagital mandibular advancement. All tracings were performed in lateral cephalometric radiographs obtained one week before surgery. The intraclass correlation coefficient analysis (ICC), the t test adjusted for Tukey-Kramer test and Schuirmann test were applied. The results showed that the manual tracings and Nemotec® tracing had excellent reliabilities for all measures (ICC > 0.98). The Dolphin Imaging® showed low reliability in anterior facial height (value of ICC = 0.70), Co-A (value of ICC = 0.47) and Co-Gn (ICC value = 0.49). In A-Nperp, Pg-Nperp, Mandibular plan, SNA and SNB there were no differences between the 3 tracings (p > 0.05), for the anterior facial height measures differences were found between the Dolphin Imaging® and Nemotec® tracings, but no differences were observed as compared to the manual tracing (p > 0.05), in Co-A and Co-Gn measures t Dolphin Imaging® presented a significantly lower mean than the other methods (p > 0.05). The manual tracings were equivalent in 6 of 8 measures (A-Nperp, Pg-Nperp, md Plan, SNA, SNB and Co-A), there was no equivalence between the methods in the anterior facial height and Co-Gn measures (p < 0.01). The Dolphin Imaging® method was not equivalent in any of the 8 measures. It was concluded that in the manual tracing only the Co- Gn, Pg-Nperp and SNB measures confirmed the diagnosis of mandibular retrognathism, and the Nemotec® software showed better results than the Dolphin Imaging® software.
