| Investigating the Association between Eating Self-Efficacy and Emotional Eating: The Parallel Mediating Roles of Shame and Guilt in Women with Overweight and Obesity | | Author : Nazli Tavakoli1, Mohammadreza Seyrafi2*, Mehdi Manouchehri3, Abdolreza Norouzy4, Gholamreza Sarami Foroushani5 | | Abstract | Full Text | Abstract :Objective: The study investigated the direct and indirect pathways between eating self-efficacy and emotional eating behavior in women with overweight and obesity, evaluating the parallel mediating roles of shame and guilt related to body and weight.
Materials and Methods: A total of 228 women between the ages of 18 and 70, with overweight and obesity (Body Mass Index= 25), were recruited through purposive sampling. Participants completed online questionnaires: Demographic Information Questionnaire (DIQ), Dutch Eating Behavior Questionnaire (DEBQ), Weight- and Body-Related Shame and Guilt Scale (WEB-SG), Weight Efficacy Lifestyle-Short Form (WEL-SF). Descriptive statistics and parallel mediation analysis (PROCESS model 4) with bootstrapping were used to test the hypothesized model. SPSS version 23 was used to analyze the data.
Results: Higher levels of eating self-efficacy were directly associated with the lower levels of emotional eating behavior (P< 0.001), and indirectly related to reduced emotional eating by decreased weight- and body-related shame and guilt (P< 0.05). Shame and guilt served as partial, parallel mediators. The model explained 39% of the variance in emotional eating behavior (R2= 0.39).
Conclusion: This study underscores the importance of addressing cognitive and emotional factors in interventions to improve eating behaviors and manage obesity in women, providing actionable insights for healthcare professionals and researchers.

The present study aimed to investigate the effectiveness of compassion-based therapy (CBT) on rumination and concern in patients with type 1 diabetes.
Materials and Methods: A quasi-experimental study evaluated the effect of CBT on women with type 1 diabetes. Thirty women with type 1 diabetes, recruited from Qazvin city health centers between October 2024 and March 2025 and meeting inclusion criteria, were purposively sampled and randomly assigned to the CBT (n= 15) or control (n= 15) group. The intervention group received eight weekly 90-minute sessions. The control group received no intervention. The Pennsylvania State Worry Questionnaire (PSWQ) and Rumination Questionnaire (RQ) were administered pre- and post-intervention, and data were analyzed using ANCOVA in SPSS version 26.
Results: A comprehensive analysis of variance has revealed notable disparities between the experimental and control groups in terms of worry and rumination. The results indicate a moderate effect size for worry (?= 0.29; F= 10.63; P= 0.003). Similarly, rumination also shows a strong effect size (?= 0.39; F= 17.23; P< 0.001).
Conclusion: CBT effectively reduces rumination and worry in patients with type I diabetes in Qazvin, suggesting its potential as a supportive treatment for these symptoms.

| Assessing the Association between Anti-Diabetic Medication Adherence and Glycemic Control in Type 2 Diabetes | | Author : Aida Vatan Meidanshahi1, Fariba Alaei-Shahmiri1, Fatemeh Golgiri1, Mohammad Ali Mavvaji2, Bentolhoda Dinko1, Raziyah Shahi3, Sedighe Moradi1* | | Abstract | Full Text | Abstract :Objective: Adherence to anti-diabetic medications in diabetic patients plays a considerable role in glycemic control, prevention of short-term and long-term morbidities, and diabetes-related mortality. The current study aims to evaluate the factors associated with adherence to medications among patients with type 2 diabetes.
Materials and Methods: The current study was conducted on 366 diabetic patients who were referred to the Institute of Endocrinology and Metabolism. The HbA1C was measured at baseline and then after six months. The validated questionnaire on adherence to refills and medication scale (ARMS) was filled, and factors associated with medication adherence were assessed. The higher ARMS scores represented poorer adherence to the medication.
Results: Diabetic patients with adherence to anti-diabetic agents represented significantly lower levels of HbA1C both at baseline (P< 0.001) and the six-month follow-up (P< 0.001) compared to the non-adherent group. In the correlation analyses, the ARMS score was significantly correlated with the A1C levels measured at the baseline (rs= 0.37, P< 0.001) and after 6 months (rs= 0.40, P< 0.001) as well as the duration of diabetes (rs= 0.16, P= 0.003). The subsequent logistic regression analysis highlighted the use of insulin as the main determinant of adherence to medications (OR: 0.59; 95%CI: 0.35-0.99), after controlling for age, gender, diabetes duration and number of medications.
Conclusion: The current study revealed that adherence to the anti-diabetic medication is associated with remarkably improved glycemic control. Diabetes duration and insulin use were inversely correlated with adherence to medication, while there was no association with age, gender, numbers of drugs.

| Orchestrating Metabolic Homeostasis: The Role of Gut Hormones in Next-Generation Therapies for Metabolic Syndrome | | Author : Tamer A. Addissouky | | Abstract | Full Text | Abstract :Metabolic disorders, including obesity and type 2 diabetes, have reached epidemic proportions globally, necessitating novel therapeutic approaches. The gut-brain axis, particularly gut hormones, plays a crucial role in metabolic regulation, offering promising targets for intervention.
This review aims to synthesize current knowledge on gut hormone-based therapies for metabolic disorders, focusing on their mechanisms of action and therapeutic potential.
Gut hormones, including GLP-1, GIP, PYY, ghrelin, and oxyntomodulin, orchestrate complex physiological responses to nutrient intake, influencing insulin secretion, appetite, and energy expenditure. Recent advancements in incretin-based therapies, particularly GLP-1 receptor agonists and dual GLP-1/GIP agonists, have shown remarkable efficacy in improving glycemic control and promoting weight loss. These therapies exploit the synergistic actions of multiple gut hormones, offering a more comprehensive approach to metabolic regulation. Emerging research on PYY analogs and ghrelin antagonists further expands the therapeutic landscape. However, challenges remain in optimizing delivery methods, ensuring long-term efficacy, and mitigating potential side effects.
Gut hormone-based therapies represent a paradigm shift in the management of metabolic disorders. By harnessing the intricate signaling networks of the gut-brain axis, these innovative approaches offer the potential for more effective and targeted interventions in obesity and type 2 diabetes, paving the way for personalized treatment strategies in metabolic medicine.
