Comparing Internalization of Appearance Ideals and Appearance-Related Pressures Among Women from the United States, Italy, England, and Australia

Researchers have observed variation in levels of body image disturbance and eating pathology among women from different Western countries. Examination of cross-cultural differences in the established risk factors (i.e., thin-ideal internalization, muscular-ideal internalization, and appearance pressures from family, peers, and media) for negative outcomes may help to elucidate the prominence of specific risk factors within a given Western society and guide associated interventions. Women from the United States (US), Italy, England, and Australia completed the Sociocultural Attitudes Towards Appearance Questionnaire-4 (SATAQ-4). Analysis of covariance controlling for age and BMI indicated significant cross-country differences for all SATAQ-4 subscales. Results typically indicated higher levels of appearance-ideal internalization and appearance pressures in the US and lower levels in Italy; however, associated effect sizes were generally small. A medium effect of country was observed for peer-appearance pressures, which were highest in the US compared with all other countries. Repeated-measures analysis of variance and paired samples t tests conducted within each country identified thin-ideal internalization and media appearance pressures as the predominant risk factors for all four countries. Overall, findings suggest more cross-country similarities than differences, and highlight the importance of delivering interventions to address thin-ideal internalization and media appearance pressures among women from Western backgrounds

The developmental effects of media-ideal internalization and self-objectification processes on adolescents’ negative body-feelings, dietary restraint, and binge eating

Despite accumulated experimental evidence of the negative effects of exposure to media-idealized images, the degree to which body image, and eating related disturbances are caused by media portrayals of gendered beauty ideals remains controversial. On the basis of the most up-to-date meta-analysis of experimental studies indicating that media-idealized images have the most harmful and substantial impact on vulnerable individuals regardless of gender (i.e., “internalizers” and “self-objectifiers”), the current longitudinal study examined the direct and mediated links posited in objectification theory among media-ideal internalization, self-objectification, shame and anxiety surrounding the body and appearance, dietary restraint, and binge eating. Data collected from 685 adolescents aged between 14 and 15 at baseline (47 % males), who were interviewed and completed standardized measures annually over a 3-year period, were analyzed using a structural equation modeling approach. Results indicated that media-ideal internalization predicted later thinking and scrutinizing of one’s body from an external observer’s standpoint (or self-objectification), which then predicted later negative emotional experiences related to one’s body and appearance. In turn, these negative emotional experiences predicted subsequent dietary restraint and binge eating, and each of these core features of eating disorders influenced each other. Differences in the strength of these associations across gender were not observed, and all indirect effects were significant. The study provides valuable information about how the cultural values embodied by gendered beauty ideals negatively influence adolescents’ feelings, thoughts and behaviors regarding their own body, and on the complex processes involved in disordered eating. Practical implications are discussed

Silver sulfadiazine eradicates antibiotic-tolerant Staphylococcus aureus and Pseudomonas aeruginosa biofilms in patients with infected diabetic foot ulcers

Infections are among the most frequent and challenging events in diabetic foot ulcers (DFUs). Pathogenic bacteria growing in biofilms within host tissue are highly tolerant to environmental and chemical agents, including antibiotics. The present study was aimed at assessing the use of silver sulfadiazine (SSD) for wound healing and infection control in 16 patients with DFUs harboring biofilm-growing Staphylococcus aureus and Pseudomonas aeruginosa. All patients received a treatment based on a dressing protocol including disinfection, cleansing, application of SSD, and application of nonadherent gauze, followed by sterile gauze and tibio-breech bandage, in preparation for toilet surgery after 30 days of treatment. Clinical parameters were analyzed by the T.I.M.E. classification system. In addition, the activity of SSD against biofilm-growing S. aureus and P. aeruginosa isolates was assessed in vitro. A total of 16 patients with S. aureus and P. aeruginosa infected DFUs were included in the study. Clinical data showed a statistically significant (p < 0.002) improvement of patients’ DFUs after 30 days of treatment with SSD with significant amelioration of all the parameters analyzed. Notably, after 30 days of treatment, resolution of infection was observed in all DFUs. In vitro analysis showed that both S. aureus and P. aeruginosa isolates developed complex and highly structured biofilms. Antibiotic susceptibility profiles indicated that biofilm cultures were significantly (p ≤ 0.002) more tolerant to all tested antimicrobials than their planktonic counterparts. However, SSD was found to be effective against fully developed biofilms of both S. aureus and P. aeruginosa at concentrations below those normally used in clinical preparations (10 mg/mL). These results strongly suggest that the topical administration of SSD may represent an effective alternative to conventional antibiotics for the successful treatment of DFUs infected by biofilm-growing S. aureus and P. aeruginosa

The importance of perceptual experience in the esthetic appreciation of the body.

Several studies suggest that sociocultural models conveying extreme thinness as the widespread ideal of beauty exert an important influence on the perceptual and emotional representation of body image. The psychological mechanisms underlying such environmental influences, however, are unclear. Here, we utilized a perceptual adaptation paradigm to investigate how perceptual experience modulates body esthetic appreciation. We found that the liking judgments of round bodies increased or decreased after brief exposure to round or thin bodies, respectively. No change occurred in the liking judgments of thin bodies. The results suggest that perceptual experience may shape our esthetic appreciation to favor more familiar round body figures. Importantly, individuals with more deficits in interoceptive awareness were less prone to increase their liking ratings of round bodies after exposure, suggesting a specific risk factor for the susceptibility to the influence of the extreme thin vs. round body ideals of beauty portrayed by the media

Divergence of gut permeability and mucosal immune gene expression in two gluten-associated conditions: celiac disease and gluten sensitivity

<p>Abstract</p> <p>Background</p> <p>Celiac disease (CD) is an autoimmune enteropathy triggered by the ingestion of gluten. Gluten-sensitive individuals (GS) cannot tolerate gluten and may develop gastrointestinal symptoms similar to those in CD, but the overall clinical picture is generally less severe and is not accompanied by the concurrence of tissue transglutaminase autoantibodies or autoimmune comorbidities. By studying and comparing mucosal expression of genes associated with intestinal barrier function, as well as innate and adaptive immunity in CD compared with GS, we sought to better understand the similarities and differences between these two gluten-associated disorders.</p> <p>Methods</p> <p>CD, GS and healthy, gluten-tolerant individuals were enrolled in this study. Intestinal permeability was evaluated using a lactulose and mannitol probe, and mucosal biopsy specimens were collected to study the expression of genes involved in barrier function and immunity.</p> <p>Results</p> <p>Unlike CD, GS is not associated with increased intestinal permeability. In fact, this was significantly reduced in GS compared with controls (<it>P </it>= 0.0308), paralleled by significantly increased expression of claudin (CLDN) 4 (<it>P </it>= 0.0286). Relative to controls, adaptive immunity markers interleukin (IL)-6 (<it>P </it>= 0.0124) and IL-21 (<it>P </it>= 0.0572) were expressed at higher levels in CD but not in GS, while expression of the innate immunity marker Toll-like receptor (TLR) 2 was increased in GS but not in CD (<it>P </it>= 0.0295). Finally, expression of the T-regulatory cell marker FOXP3 was significantly reduced in GS relative to controls (<it>P </it>= 0.0325) and CD patients (<it>P </it>= 0.0293).</p> <p>Conclusions</p> <p>This study shows that the two gluten-associated disorders, CD and GS, are different clinical entities, and it contributes to the characterization of GS as a condition associated with prevalent gluten-induced activation of innate, rather than adaptive, immune responses in the absence of detectable changes in mucosal barrier function.</p

Different contributions of visual and motor brain areas during liking judgments of same- and different-gender bodies

Previous neuroimaging studies have shown that body aesthetic appreciation involves the activation of both visual and motor areas, supporting a role of sensorimotor embodiment in aesthetic processing. Causative evidence, however, that neural activity in these areas is crucial for reliable aesthetic body appreciation has so far provided only for extrastriate body area (EBA), while the functional role played by premotor regions remained less clear. Here, we applied short trains of repetitive transcranial magnetic stimulation (rTMS) over bilateral dorsal premotor cortex (dPMC) and EBA during liking judgments of female and male bodies varying in weight and implied motion. We found that both dPMC and EBA are necessary for aesthetic body appreciation, but their relative contribution depends on the model's gender. While dPMC-rTMS decreased the liking judgments of same-, but not of different-gender models, EBA-rTMS increased the liking judgments of different-, but not of same-gender models. Relative contributions of motor and visual areas may reflect processing of diverse aesthetic properties, respectively implied motion vs. body form, and/or greater sensorimotor embodiment of same- vs. different-gender bodies. Results suggest that aesthetic body processing is subserved by a network of motor and visual areas, whose relative contribution may depend on the specific stimulus and task
