AI Article Synopsis
- Bariatric surgery is effective for long-term weight loss, but not all patients achieve expected results.
- The study included 140 participants, measuring factors like eating disorders, impulsivity, and depression in relation to weight loss success (≥ 50% of excess weight).
- Results showed that over 81% of participants were successful, but those with suboptimal weight loss exhibited more eating disorder symptoms, impulsivity, and depression, indicating these factors hinder weight loss achievement.
- The findings suggest that addressing these psychological and behavioral issues could improve outcomes for patients post-surgery.
Article Abstract
Purpose: Bariatric surgery is the most effective long-term treatment for sustained weight loss in obesity. Studies have shown that not all patients lose the expected amount of weight. The aim of this study was to develop a better understanding of which behavioral and psychological factors are associated with suboptimal weight loss.
Methods: The present paper describes a cross-sectional study that included 140 participants. The mean follow-up period after bariatric surgery was 3.16 years. Eating disorder pathology (Eating Disorder Examination-Questionnaire), impulsivity (Barratt Impulsiveness scale-II) and depressive symptoms (Beck Depression Inventory) were compared with successful and suboptimal participants. A weight loss of more than or equal to 50% of excess weight, was considered to be successful.
Results: More than 81% of the participants met the criterion for successful weight loss. The suboptimal weight loss group reported more symptoms of eating disorder pathology (p = .001), more loss of control over eating (p = .001), and more avoidant behavior due to poor body image (p < .001). The suboptimal weight loss group scored higher on impulsivity (p = .007) and on depression (p < .001). More early weight loss was associated with better weight outcome later on (r = .491). Reporting more eating disorder pathology, a longer follow-up period and pre-operative super-obesity (body mass index ≥ 50 kg/m) at the time of surgery were associated with poorer weight loss (p < .001).
Conclusion: Eating disorder pathology, loss of control over eating and avoidant behavior due to poor body image, as well as depressive symptoms and impulsivity, (as reported postoperatively) are associated with suboptimal weight loss. Level III: Case-control analytic study.

In order to investigate the impact of hot air (HA) treatment on the sugars and volatiles in postharvest nectarine fruit, nectarines were treated with HA at 40 °C for 4 h and stored at 1 °C for 35 days. Changes of sugars, free and glycosidically bound volatiles, β-glucosidase (β-Glu) activity, and the gene expression of UGT (UDP-glucosyltransferase) in nectarine fruit were determined. The results showed that compared with CK, HA treatment delayed the firmness decline of 48.

Cachexia is a systemic wasting syndrome prevalent in patients with cancer that significantly affects quality of life, health care costs, and therapeutic outcomes. Despite its clinical importance, cachexia is rarely formally diagnosed. This deficiency presents a challenge for effective patient management and care, health care resource allocation, and the advancement of therapeutic approaches.
