Purpose: Self-discrepancy (i.e., perceived differences between one's actual self and personal standards) has been associated with binge eating disorder (BED) symptoms. However, little is known about how weight discrepancy (i.e., the difference between one's actual and ideal weights) interacts with or is distinguished from nonappearance self-discrepancy (discrepancy unrelated to weight or shape) in predicting BED severity. The current study examined how these two forms of discrepancy independently and interactively relate to BED and associated symptoms to elucidate how facets of self-discrepancy may operate to precipitate and maintain BED.
Methods: Adults with BED (N = 111) completed questionnaires and interviews prior to treatment that assessed self-discrepancy (computerized selves) and weight discrepancy (assessed during the Eating Disorder Examination [EDE]) as predictors of global eating disorder (ED) symptomatology (EDE Global score), depression (Beck Depression Inventory), anxiety (State-Trait Anxiety Inventory), self-esteem (Rosenberg Self-Esteem Scale), and ED-related impairment (Clinical Impairment Assessment).
Results: Multivariate regression models indicated nonappearance self-discrepancy and weight discrepancy were not significantly related to the severity of global ED symptoms, but both independently predicted impairment (ps < 0.05). Nonappearance self-discrepancy, but not weight discrepancy, was also associated with higher depression (p = 0.001), anxiety (p < 0.001), and lower self-esteem (p < 0.001).
Conclusion: These findings suggest distinct associations of weight discrepancy and nonappearance self-discrepancy with ED and related symptoms, as well as each of these constructs' relevance to everyday functioning in BED. The results also highlight potential avenues for future research to examine mechanistic pathways by which self-discrepancy influences BED severity.

Objective: The extent of resection (EOR) is an important prognostic factor for both low- and high-grade gliomas. Intraoperative MRI (iMRI) has been used to increase the EOR in glioma surgery. While a recent study reported differences between iMRI and early postoperative MRI (epMRI), their specific relationship to postoperative clinical symptoms remains unclear.

Objective: To evaluate the precision and accuracy of 3 common methods (method 1, actual draws of the volume remaining; method 2, weight tracking of the volume remaining and/or the volume removed; and method 3, discrepancy percentage at the end of each vial) for monitoring volumes in vials of injectable controlled drugs.
Methods: For methods 1 and 2, doses were drawn from a vial containing a known amount of sterile water. For method 1, after each dose was removed, the remaining quantity of liquid was withdrawn, measured, and reinjected into the vial.
Intragastric botulinum toxin injection for weight loss: current trends, shortcomings and future perspective.

The administration of botulinum toxin A (BTA) into the gastric wall has emerged as a novel endoscopic bariatric procedure. Although over 20 years have elapsed since the initial human trial of intragastric BTA injection, considerable debate remains surrounding the safety, efficacy, and procedural instructions of this approach. The current literature exhibits discrepancies in the methodologies employed across studies, including differences in the dosage of BTA administered, injection site, number and depth of injections, post-procedural dietary modifications, and follow-up duration.

Discrepancies exist between these methods, potentially related to the AP necrosis area. This study evaluated these discrepancies and the extent of AP necrotic lesions.

Maternal obesity decreases infant energy expenditure, subsequently predisposing infants to greater adiposity and weight gain. Conversely, some findings suggest that maternal exercise may increase infant energy expenditure; however, the impact of maternal exercise mode (i.e.
