    Comparison of CR10 Borgs Scale with Visual Analogue Scale (VAS) to assess pain in patients with Temporomandibular Disorders

    No full text
    A Visual Analogue Scale (VAS) e a escala Category-Ratio (CR10) foram aplicadas para mensurar a dor em pacientes com Disfunções Temporomandibulares (DTMs) em dois estudos. No primeiro estudo, em 35 pacientes (Grupo I) foram aplicadas uma versão modificada da escala CR10 em português e a VAS para mensurar a dor espontânea, durante função orofacial e durante palpação antes e após tratamento odontológico. A modificação na CR10 consistiu em um desmembramento das categorias verbais e da escala numérica apresentadas cada uma delas em única coluna em mesma folha. Os coeficientes de correlação de Pearson entre as pontuações da VAS e da CR10 foram 0,85 antes do tratamento odontológico e 0,9 após o tratamento, indicando alta validade de critério. A associação entre os valores numéricos e as categorias verbais da Escala CR10 Modificada mostrou diferenças em relação ao que é proposto na escala original. As categorias: Moderado", Forte" e Muito Forte" foram associadas a valores superiores aos originais. O segundo estudo foi planejado para investigar se essas discrepâncias nas associações das categorias com os seus valores numéricos eram replicáveis e verificar se não dependiam da forma de apresentação da escala CR10 modificada. Para isso, as escalas foram aplicadas para medir dor em duas novas amostras de pacientes com DTMs antes do tratamento odontológico. A CR10 com nova modificação e a VAS foram aplicadas à primeira amostra (Grupo II , n=23 pacientes). A modificação na CR10 consistiu na apresentação primeiro da escala numérica em uma coluna seguida pela apresentação das categorias verbais em três colunas. A CR10 original e a VAS foram aplicadas à segunda amostra (Grupo III, n=17 pacientes). Os coeficientes de correlação de Pearson foram 0,9 para o Grupo II e 0,8 para o Grupo III, indicando também alta validade de critério. Assim como no primeiro estudo, na escala CR10, as categorias verbais: Moderado", Forte" e Muito Forte" foram associadas na escala numérica a valores superiores aos propostos na escala original Em ambos estudos, a escala CR10 foi a mais bem avaliada pelos pacientes, segundo a facilidade de compreensão das instruções e a adequação para o registro da dor. Evidencia-se a necessidade de mais estudos para validar a escala CR10 para a língua portuguesa para determinar com precisão a associação das categorias verbais aos valores numéricos.Visual Analogue Scale (VAS) and Category-Ratio Scale (CR10) were applied to measure pain in patients with Temporomandibular Disorders (TMDs). In the first study, a modified version of CR10 translated to Portuguese and VAS were applied to measure spontaneous pain, functional pain and pain by touch after and before dentistry treatment in 35 patients (Group I). The CR10 modification consisted of presenting the verbal categories and the numerical scale in separated columns in a sheet. Coefficients of Pearsons correlation between VAS and CR10 scores were .85 and .90 respectively before and after treatment, indicating a high criterion validation. The association of numerical values and verbal categories of Modified CR10 scale were different from the original CR10. The verbal expressions moderate", strong" and very strong" were attached to higher values. In the second study we investigated if these discrepancies in attaching the verbal categories to the numerical scale were replicable and if they were not an artifact of the way of presenting the modified CR10 scale. To check these topics, the scales were applied to measure pain in two new samples of patients with TMD before dentistry treatment. A new modified version of the CR10 scale and the VAS were applied to the first sample (Group II, n=23 patients). This modification in CR10 scale consisted of presenting first the numerical scale in separate column, and then the verbal categories distributed in three columns. The original CR10 and VAS were applied to the second sample (Group III, n=17 patients). Coefficients of Pearsons correlation between CR10 and VAS were .9 for Group II and .8 for Group III, indicating also high criterion validation. As indicated in the first study, some verbal categories were attached to the numerical scale at higher values than those ones in the original scale. In both studies,, most patients judged the CR10 easier to be understood and more adequate to measure pain than VAS. There is evidence of the necessity of more studies to validate CR10 to Portuguese to determine with precision the association of the verbal categories to the numeric values

    Bruxism has a multifactorial etiology, and psychosocial factors have been considered to increase the risk of occurrence of this parafunction. The aim of this study was to evaluate the behavior profile of a group of children diagnosed with bruxism. Eighty 7-11-year-old children of both genders (mean age 8.8 years) first recruited as eligible participants. Twenty-nine children (18 males and 11 females) whose parents/guardians reported to present frequent episodes of tooth grinding/clenching while awake or during sleep (at least 3 nights a week) in the previous 3 months were enrolled in the study. The diagnosis of bruxism was established based on the parents/guardians' report about the children's behavior, habits and possible discomforts in the components of the stomatognathic system allied to the presence of signs and symptoms such as pain on the masticatory muscles, masseter muscle hypertrophy, wear facets, fractures of restorations, dental impressions on the cheek mucosa and tongue. As part of the psychological evaluation, the Rutter's Child Behavior Scale-A2 was applied to the parents/caregivers (one for each child) and the Child Stress Scale was applied to the children. Data were analyzed descriptively based on the frequency of each studied variable. Twenty-four (82.76%) children needed psychological or psychiatric intervention; 17 of them presented neurotic disorders and 7 children presented antisocial disorders. Six (20.70%) children presented significant physical and psychological manifestations of stress. The findings of the present study suggest that behavioral problems and potential emotional problems can be risk factors to bruxism in children

    A search for the decays of the Higgs and ZZ bosons to J/ψγJ/\psi\gamma and Υ(nS)γ\Upsilon(nS)\gamma (n=1,2,3n=1,2,3) is performed with pppp collision data samples corresponding to integrated luminosities of up to 20.3fb120.3\mathrm{fb}^{-1} collected at s=8TeV\sqrt{s}=8\mathrm{TeV} with the ATLAS detector at the CERN Large Hadron Collider. No significant excess of events is observed above expected backgrounds and 95% CL upper limits are placed on the branching fractions. In the J/ψγJ/\psi\gamma final state the limits are 1.5×1031.5\times10^{-3} and 2.6×1062.6\times10^{-6} for the Higgs and ZZ bosons, respectively, while in the Υ(1S,2S,3S)γ\Upsilon(1S,2S,3S)\,\gamma final states the limits are (1.3,1.9,1.3)×103(1.3,1.9,1.3)\times10^{-3} and (3.4,6.5,5.4)×106(3.4,6.5,5.4)\times10^{-6}, respectively

    Measurements of the Total and Differential Higgs Boson Production Cross Sections Combining the H??????? and H???ZZ*???4??? Decay Channels at s\sqrt{s}=8??????TeV with the ATLAS Detector

    No full text
    Measurements of the total and differential cross sections of Higgs boson production are performed using 20.3~fb1^{-1} of pppp collisions produced by the Large Hadron Collider at a center-of-mass energy of s=8\sqrt{s} = 8 TeV and recorded by the ATLAS detector. Cross sections are obtained from measured HγγH \rightarrow \gamma \gamma and HZZ4H \rightarrow ZZ ^{*}\rightarrow 4\ell event yields, which are combined accounting for detector efficiencies, fiducial acceptances and branching fractions. Differential cross sections are reported as a function of Higgs boson transverse momentum, Higgs boson rapidity, number of jets in the event, and transverse momentum of the leading jet. The total production cross section is determined to be σppH=33.0±5.3(stat)±1.6(sys)pb\sigma_{pp \to H} = 33.0 \pm 5.3 \, ({\rm stat}) \pm 1.6 \, ({\rm sys}) \mathrm{pb}.

    Professionals within the judicial system sometimes believe they can assess whether someone is lying or not based on cues such as body language and emotional expression. Research has, however, shown that this is impossible. The Finnish Supreme Court has also given rulings in accordance with this demonstrated fact. There has also been previous research on whether party or witness statements are assessed differently in court depending on whether they are given live, via videoconference, or via prerecorded video. In the present study, we investigated how a Finnish sample of district judges (N=47) assigned probative value to different variables concerning the statement or the statement giver, such as body language and emotional expression. We also investigated the connection between the judges’ beliefs about the relevance of body language and emotional expression and their preference for live statements or statements via videoconference. The judges reported assigning equal amounts of probative value to statements given live and statements given via videoconference. However, judges found it easier to detect deception live, and this preference correlated with how relevant they thought body language is when assessing the probative value of the statement. In other words, a slight bias to assess live statements more favorably than statements given via videoconference might still exist. More effort needs to be put into making judges and Supreme Courts aware of robust scientific results that have been the subject of decades of research, such as the fact that one cannot assess whether someone is lying or not based on cues such as body language
