- ObjectiveMeal pattern is an important variable in both obesity treatment and treatment for eating disorders. Momentary assessment and eating diaries are highly valid measurement methods but often cumbersome and not always feasible to use in clinical practice. The aim of this study was to design and evaluate a self-report instrument for measuring meal patterns.MethodThe Pattern of eating item from the Eating Disorder Examination (EDE) interview was adapted to self-report format to follow the same overall structure as the Eating Disorder Examination Questionnaire. The new instrument was named the Meal Patterns Questionnaire (MPQ) and was compared with the EDE in a student sample (n = 105) and an obese sample (n = 111).ResultsThe individual items of the MPQ and the EDE showed moderate to high correlations (rho = .63–89) in the two samples. Significant differences between the MPQ and EDE were only found for two items in the obese sample. The total scores correlated to a high degree (rho = .87/.74) in both samples and no significant differences were found in this variable.DiscussionThe MPQ can provide an overall picture of a person's eating patterns and is a valid way to collect data regarding meal patterns. The MPQ may be a useable tool in clinical practice and research studies when more extensive instruments cannot be used. Future studies should evaluate the MPQ in diverse cultural populations and with more ecological assessment methods.

- Previous studies have separately examined conformity tomasculine norms and internalization of body ideals in themedia in relation to the drive formuscularity (DM). This study was designed to examine these factors together in relation toDM, and further examine howtheymay differ in relation to drive for thinness (DT) and drive for leanness (DL). Participants were 284 Australian males between ages 18 and 42. They completed validated measures that assessed DM, DT, DL, male gender role norms, and internalization of body ideals. The findings showed that internalization of body ideals mediated the relationship between masculine role norms and body image in the case of both DM and DL. However, masculine norms and internalization were independent predictors of DT. Our findings contribute to further understanding of the roles that the media and masculine norms have in shaping men's drive for muscularity, leanness, and thinness. Longitudinal research is needed to confirm the nature and direction of these relationships. (C) 2015 Elsevier Ltd. All rights reserved.

- Literature has shown that young women present high rates of body dissatisfaction, independently of their weight. Therefore, dieting may emerge as a strategy to control one's body image. Nonetheless, it also seems to be a source of great suffering rather than a solution.The aim of the present study was to explore what variables explain the inflexible engagement in eating rules. Our hypothesis is that an inflexible eating pattern results not exclusively from weight and body dissatisfaction and shame but mainly from emotional regulation processes (such as body image-related cognitive fusion).The sample of the present study comprised 659 female college students, aged between 18 and 25 years old, who completed self-report measures.Results revealed that the majority of the normal-weight participants desired to lose weight and to have a thinner body shape. Findings from the path analyses demonstrated that the effects of weight dissatisfaction and shame on the inflexible adhesion to eating rules were fully mediated through the mechanism of body image-related cognitive fusion. Furthermore, the effect of body dissatisfaction was partially operated by this process. This model was controlled by BMI and explained a total of 36% of inflexible adhesion to eating rules.In conclusion, these findings suggest that it is when a woman gets fused and entangled with her body image-related thoughts that these unwanted inner events most impact on her eating rules. This study thus offers important new data for research and clinical practise in the field of body image and eating difficulties.

Eosinophils may play regionally disparate roles in influencing IgA+ plasma cell numbers during large and small intestinal inflammation

- Background: Eosinophils are innate immune cells present in the intestine during steady state conditions. An intestinal eosinophilia is a hallmark of many infections and an accumulation of eosinophils is also observed in the intestine during inflammatory disorders. Classically the function of eosinophils has been associated with tissue destruction, due to the release of cytotoxic granule contents. However, recent evidence has demonstrated that the eosinophil plays a more diverse role in the immune system than previously acknowledged, including shaping adaptive immune responses and providing plasma cell survival factors during the steady state. Importantly, it is known that there are regional differences in the underlying immunology of the small and large intestine, but whether there are differences in context of the intestinal eosinophil in the steady state or inflammation is not known. Results: Our data demonstrates that there are fewer IgA+ plasma cells in the small intestine of eosinophil-deficient ΔdblGATA-1 mice compared to eosinophil-sufficient wild-type mice, with the difference becoming significant post-infection with Toxoplasma gondii. Remarkably, and in complete contrast, the absence of eosinophils in the inflamed large intestine does not impact on IgA+ cell numbers during steady state, and is associated with a significant increase in IgA+ cells post-infection with Trichuris muris compared to wild-type mice. Thus, the intestinal eosinophil appears to be less important in sustaining the IgA+ cell pool in the large intestine compared to the small intestine, and in fact, our data suggests eosinophils play an inhibitory role. The dichotomy in the influence of the eosinophil over small and large intestinal IgA+ cells did not depend on differences in plasma cell growth factors, recruitment potential or proliferation within the different regions of the gastrointestinal tract (GIT). Conclusions: We demonstrate for the first time that there are regional differences in the requirement of eosinophils for maintaining IgA+ cells between the large and small intestine, which are more pronounced during inflammation. This is an important step towards further delineation of the enigmatic functions of gut-resident eosinophils.
