Confirmatory factor analysis and measurement invariance of the eating disorders examination-questionnaire across four male samples in Argentina.

OBJECTIVE: The eating disorder examination-questionnaire (EDE-Q) is among the most widely used instruments in eating disorder research and clinical practice. However, the underlying structure remains a source of confusion, and contradictory results have emerged in studies among male populations. In the current study, we examined previously proposed models of EDE-Q structure in four community samples of Argentinian men. METHOD: A series of confirmatory factor analyses (CFAs) were performed for five previous factor structure models of the EDE-Q among 232 Argentinian male university students, 277 weightlifters, 275 cross-fit users, and 202 athletes. A multigroup CFA was conducted in the model we retained, to assess measurement invariance across groups. RESULTS: A respecified model of the brief eight-item one-factor proposal provided acceptable fit to the data over the original four-factor structure and three other proposed models. Results from the multigroup CFA showed that the retained model was invariant across samples. CONCLUSION: Our results provide support for retaining a one-factor EDE-Q structure over a multifactor solution for research purposes among male community samples in Argentina. These data underscore the importance of undertaking psychometric assessment of eating disorder symptom measures before their utilization in specific populations.

What position do you play? Eating disorder pathology among rugby players, and the understudied role of player position.

OBJECTIVE: Male athletes appear to be at high risk for Eating Disorders (ED), given sport-related pressures. Although in some sports weight loss confers a competitive advantage, men also participate in sports where a large body is considered to enhance performance. In rugby a heavier body has been associated with sports success, however, physical demands vary given the position in the field (forward or back). We aimed to investigate whether ED pathology varied as a function of player position. METHOD: A cross-sectional study was conducted among 203 rugby players (Mage = 21.78, SD = 3.54) in order assess associations between elevated eating pathology given the players' position, and with ED mediating mechanisms (physical comparison and exercise dependence). RESULTS: 8.9% (95% CI: 4.9, 12.8) of the participants presented elevated eating pathology. Players' position, physical comparison and exercise dependence were associated with elevated eating pathology. Forwards tended to endorse binge eating more frequently, and showed higher levels of eating concerns. DISCUSSION: Our findings suggest that ED symptoms differ as a function of player position, and that elevated eating pathology in rugby players is associated with appearance comparison and exercise dependence. Despite the possible implications for prevention and treatment efforts, the clinical validity of the current findings must be confirmed with further research.

Occurrence of Chlamydiaceae and Chlamydia felis pmp9 Typing in Conjunctival and Rectal Samples of Swiss Stray and Pet Cats.

Chlamydia (C.) felis primarily replicates in feline conjunctival epithelial cells and is an important cause of conjunctivitis in cats. Data on C. felis infection rates in stray cats in Switzerland has been missing so far. We performed a qPCR-based Chlamydiaceae-screening on 565 conjunctival and 387 rectal samples from 309 stray and 86 pet cats followed by Chlamydia species identification and C. felis typing using the gene pmp9, which encodes a polymorphic membrane protein. Overall, 19.1% of the stray and 11.6% of the pet cats were Chlamydiaceae-positive with significantly higher rates in cats displaying signs of conjunctivitis (37.1%) compared to healthy animals (6.9%). Rectal shedding of Chlamydiaceae occurred in 25.0% of infected cats and was mostly associated with concurrent ocular positivity (87.5%). In 92.2% of positive conjunctival and rectal samples, the Chlamydia species was identified as C. felis and in 2.6% as C. abortus. The C. felis pmp9 gene was very conserved in the sampled population with only one single-nucleotide polymorphism (SNP) in one conjunctival sample. In conclusion, C. felis strains are circulating in Swiss cats, are associated with conjunctivitis, have a low pmp9 genetic variability, and are rectally shed in about 16% of positive cases.

Avaliação da retenção do cimento de ionômero de vidro em cavidades atípicas restauradas pela técnica restauradora atraumática / Retention's evaluation on glass ionomer cement in cavities treated by atraumatic restorative treatment

Objetivo: O objetivo deste trabalho foi avaliar a retenção doCIV em restaurações atípicas inseridas no programa de ART.Método: Foram selecionados 17 dentes decíduos, de criançascom idade entre 3 e 10 anos, da cidade de São Luiz doParaitinga - SP que apresentavam cavidades atípicas comenvolvimento de no mínimo 3 superfícies e com atividade dadoença cárie. Após 24 meses, as cavidades foram avaliadasem relação à retenção total do material restaurador, retençãoparcial do material restaurador, ou seja, se houve perda domaterial em pelo menos uma das faces envolvidas, ou perda atotal do material. Resultados: Verificou-se que houve retençãototal em 58,8 porcento das restaurações, retenção parcial em 11,8 porcentodas restaurações e ausência de 29,4 porcento das restaurações, ouseja um sucesso de 70,6 porcento das restaurações. As cavidadescom perda total do material no ato da reavaliação (29,4 porcento)apresentaram a dentina profunda com aspecto de lesão inativade cárie. Conclusão: Pôde-se concluir que há possibilidadede sucesso a longo prazo quando realizadas restaurações,usando o ART, em cavidades atípicas no tratamento da doença carie
