The EU-Emotion Stimulus Set: A validation study

Abstract: The EU-Emotion Stimulus Set is a newly developed collection of dynamic multimodal emotion and mental state representations. A total of 20 emotions and mental states are represented through facial expressions, vocal expressions, body gestures and contextual social scenes. This emotion set is portrayed by a multi-ethnic group of child and adult actors. Here we present the validation results, as well as participant ratings of the emotional valence, arousal and intensity of the visual stimuli from this emotion stimulus set. The EU-Emotion Stimulus Set is available for use by the scientific community and the validation data are provided as a supplement available for download.

Meta-analysis of air pollution exposure association with allergic sensitization in European birth cohorts

Abstract: Background Evidence on the long-term effects of air pollution exposure on childhood allergy is limited. Objective We investigated the association between air pollution exposure and allergic sensitization to common allergens in children followed prospectively during the first 10 years of life. Methods Five European birth cohorts participating in the European Study of Cohorts for Air Pollution Effects project were included: BAMSE (Sweden), LISAplus and GINIplus (Germany), MAAS (Great Britain), and PIAMA (The Netherlands). Land-use regression models were applied to assess the individual residential outdoor levels of particulate matter with an aerodynamic diameter of less than 2.5 μm (PM 2.5 ), the mass concentration of particles between 2.5 and 10 μm in size, and levels of particulate matter with an aerodynamic diameter of less than 10 μm (PM 10 ), as well as measurement of the blackness of PM 2.5 filters and nitrogen dioxide and nitrogen oxide levels. Blood samples drawn at 4 to 6 years of age, 8 to 10 years of age, or both from more than 6500 children were analyzed for allergen-specific serum IgE against common allergens. Associations were assessed by using multiple logistic regression and subsequent meta-analysis. Results The prevalence of sensitization to any common allergen within the 5 cohorts ranged between 24.1% and 40.4% at the age of 4 to 6 years and between 34.8% and 47.9% at the age of 8 to 10 years. Overall, air pollution exposure was not associated with sensitization to any common allergen, with odds ratios ranging from 0.94 (95% CI, 0.63-1.40) for a 1 × 10 −5 ∙ m −1 increase in measurement of the blackness of PM 2.5 filters to 1.26 (95% CI, 0.90-1.77) for a 5 μg/m 3 increase in PM 2.5 exposure at birth address. Further analyses did not provide consistent evidence for a modification of the air pollution effects by sex, family history of atopy, or moving status. Conclusion No clear associations between air pollution exposure and development of allergic sensitization in children up to 10 years of age were revealed.

Radiographic evaluation of maddibular posterior implant sites; correlation between panoramic and tomographic determinations

Abstract: The purpose of the present study was to compare bone height determinations of implant sites by different radiographic techniques. Available bone height was measured in regions posterior to the mental foramen on panoramic radiographs, and on tomographs where the faciolingual dimensions was at least 5mm. The one heights were recorded at 401 edentulous and denate sites in 100 patients. The overall mean bone height ±SD) was 11.25±3.29mm on panoramic radiographs and 8.81±3.38mm on tomographs. The correlation between the two radiographic techniques ranged from 0.36 to 0.91 if the material was stratified according to factors such as height of available bone, age, gender and the presence of teeth. Gender was significantly correlated to panoramic and tomographic measurements in all regions. However, the precision of predicted tomographic measurements by using a linear regression model was not significantly increased by including gender as an explanatory variable. For evaluation of available bone height in mandibular regions posterior to the mental foramen, tomography is recommended for all prospective implant sites.

Prevalence of Periodontitis in Patients with Established Rheumatoid Arthritis: A Swedish Population Based Case-Control Study.

Abstract: Introduction The possible hypothesis of a link between periodontitis and rheumatoid arthritis (RA), specifically anti-citrullinated protein antibody (ACPA) positive RA, prompted us to investigate the prevalence of periodontitis in the Swedish Epidemiological Investigation of RA (EIRA), a well-characterised population-based RA case-control cohort. Methods Periodontal status of 2,740 RA cases and 3,942 matched controls was retrieved through linking EIRA with the National Dental Health Registry (DHR), where dental diagnostic- and treatment codes on the adult Swedish population have been registered. Dental records from 100 cases and controls were reviewed to validate the periodontal diagnostic codes in DHR. Results The reviewed dental records confirmed 90% of the periodontitis diagnoses in DHR among RA cases, and 88% among controls. We found the positive predictive value of periodontitis diagnoses in the DHR to be 89% (95% CI 78 to 95%) with a sensitivity of 77% (95% CI: 65 to 86%). In total, 86% of EIRA participants were identified in DHR. The risk for periodontitis increased by age and current smoking status in both cases as well as controls. No significant differences in prevalence of periodontal disease in terms of gingivitis, periodontitis, peri-implantitis or increased risk for periodontitis or peri-implantitis were observed between RA cases and controls. In addition, there was no difference on the basis of seropositivity, ACPA or rheumatoid factor (RF), among patients with RA. Conclusions Our data verify that smoking and ageing are risk factors for periodontitis, both in RA and controls. We found no evidence of an increased prevalence of periodontitis in patients with established RA compared to healthy controls, and no differences based on ACPA or RF status among RA subjects.
