    • The purpose of the study was to investigate the relationships between changes in flexible vs. rigid restraints of eating during weight management, as well as how changes in the cognitive restraint of eating were related to psychological well-being and flexibility. The data includes information on 49 overweight persons who participated in a weight loss and maintenance (WLM) intervention and a follow-up assessment after 8-9 months. An increase in flexible cognitive restraint during the weight loss intervention was related to better weight loss maintenance and well-being. The more flexible restraint increased during the WLM intervention, the more psychological distress decreased. Moreover, larger reduction of rigid restraint during the follow-up period (between the WLM intervention and the follow-up assessment) was related to a better maintenance of improved psychological well-being at the follow-up endpoint. These results suggest that increasing flexible control while reducing rigid control of eating after an active weight loss phase improves success in weight management and the psychological well-being of weight losers.

  • Does perfectionism mediate or moderate the relation between body dissatisfaction and disordered eating attitudes and behaviors?

    • A link between perfectionism and disordered eating has been documented in previous studies. The purpose of the current study was to expand our knowledge of the specific role of perfectionism in disordered eating by examining perfectionism as a mediator or a moderator in the relation between body dissatisfaction and disordered eating (assessed using the EAT-26 and its subscales. and the Binge Scale) We sampled a large ethnically diverse sample of university women (N = 520) using two measures of perfectionism the Eating Disorder Inventory Perfectionism subscale (EDI-P) and the Multidimensional Perfectionism Scale (H-MPS) In general, socially prescribed and self-oriented perfectionism, but not other-oriented perfectionism, were correlated with disordered eating attitudes and behaviors, except binge eating. Furthermore, perfectionism was found to partially mediate and moderate the relation between body dissatisfaction and disordered eating, however the strength of these associations differed depending on both the particular measure of perfectionism (EDI-P versus H-MPS) and the specific dimension of perfectionism (self-oriented, socially prescribed, other-oriented) used in the analyses. The findings are discussed in relation to the need for more informed and theoretically sound models of the development and maintenance of disordered eating.

  • Eosinophils may play regionally disparate roles in influencing IgA+ plasma cell numbers during large and small intestinal inflammation
  • 2016

    • 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.
