Anxiety and malocclusion are associated with temporomandibular disorders in adolescents diagnosed by RDC/TMD. A cross-sectional study.

Abstract: BACKGROUND Temporomandibular Disorders (TMD) is a multifactorial condition, which could be associated to occlusal and psychological factors, such as anxiety. OBJECTIVE Investigate if anxiety and malocclusion are associated with the prevalence of TMD in adolescents. METHODS To ensure a population-based representative sample, 934 adolescents aged 10 to 14 years old from Curitiba-PR, Brazil were randomly selected and examined according to Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and malocclusion by a single-calibrated examiner (Kappa > 0.80). Anxiety was assessed according to trait anxiety (STAI-T), categorised as high, moderate and low levels. For occlusal exam, it was considered: Angel's molar relationship, anterior and posterior crossbite, excessive overjet, open and deep bite. The associations were analysed by the crude and adjusted prevalence ration (RPa ) of TMJ, calculated by a Poisson multivariate regression with robust variance (α = 0.05). RESULTS The prevalence of at least one type of malocclusion was found in 52.3%. Anxiety was found in high level (12.2%), moderate (70.4%) and low (17.5%). Presence of high anxiety was significantly associated with the prevalence of TMD symptoms (RPa = 4.06, P < 0.001), as well as the prevalence of myofascial pain (RPa = 24.78; P < 0.001) and prevalence of disc displacement with reduction (RPa = 11.08, P < 0.001). Adolescents Class II had higher prevalence of myofascial pain (Class II RPa = 1.73; P < 0.015) than adolescents Class I. Adolescents Class III presented higher prevalence of myofascial pain (PRa 2.53; P = 0.004) than adolescents Class I. CONCLUSION Anxiety is strongly associated with TMD in adolescents. Presence of Class II or III is associated with higher prevalence of myofascial pain in adolescentsPLESAE check and approve the edit made in the article title.

Propulsive force asymmetry during tethered-swimming.

Abstract: This study aimed to determine whether: i) tethe­red-swimming can be used to identify the asymmetry during front crawl swimming style; ii) swimmers that perform unilateral breathing present greater asymmetry in comparison to others that use bilateral breathing; iii) swimmers of best performance present smaller asymmetry than their counterparts; iv) repeated front crawl swimming movements influence body asymmetry. 18 swimmers were assessed for propulsive force parameters (peak force, mean force, impulse and rate of force development) during a maximal front crawl tethered-swimming test lasting 2 min. A factorial analysis showed that propulsive forces decreased at the beginning, intermediate and end of the test (p 0.05). When performance was considered (below or above mean group time), a larger asymmetry was found in the sub-group of lower performance in comparison to those of best performance (p

Thermal, rheological, and structural behaviors of natural and modified cassava starch granules, with sodium hypochlorite solutions

Abstract: The use of chemically modified starches is widely accepted in various industries, with several applications. In this research, natural cassava starch granules were treated with standard sodium hypochlorite solution at 0.8, 2.0, and 5.0 g Cl/100 g starch. The native and modified starch samples were investigated by means of the following techniques: simultaneous thermogravimetry–differential thermal analysis, which allowed us to verify the thermal decomposition associated with endothermic or exothermic phenomena; and differential scanning calorimetry that was used to determine gelatinization enthalpy as well as the rapid viscoamylographic analysis that provided the pasting temperature and viscosity. By means of non-contact-atomic force microscopy method and X-ray powder patterns diffractometry, it was possible to observe the surface morphology, topography of starch granules, and alterations in the granules’ crystallinity.

Gestão estratégica: um exame de práticas em universidades privadas

Abstract: A estrategia, como abordagem gerencial, tem se constituido em experiencia relativamente recente em organizacoes universitarias brasileiras. Este artigo tem o objetivo de analisar a pratica estrategica em universidades privadas e contribuir com o debate sobre esse topico que desafia a administracao dessas organizacoes. Trata-se de um estudo comparativo de casos onde e analisada a realidade de duas universidades comunitarias brasileiras. Por meio de questionario e entrevistas, identificaram-se praticas adotadas na gestao estrategica das instituicoes de educacao superior — IES. A analise dos dados revelou que a pratica estrategica mescla estrategias deliberadas e, principalmente, estrategias emergentes. As estrategias decorrem tanto de planos formais institucionais quanto de iniciativas in-dividuais e grupais, que resultam de interacoes, de
