Brief summary

Gastric myoelectric, inflammatory, and hormonal responses, body compositional, energy expenditure, and metabolic changes during the development of obesity and the weight loss process are underinvestigated. This project studied the myoelectrical inflammatory and hormonal responses of the stomach, in addition to energy expenditure and body composition changes during weight loss via bariatric surgery and lifestyle intervention.

Detailed description

Gastric myoelectric, inflammatory, and hormonal responses, body compositional, energy expenditure, and metabolic changes during the development of obesity and the weight loss process are underinvestigated. This project studied the myoelectrical, inflammatory, and hormonal responses of the stomach, in addition to energy expenditure and body composition changes during weight loss via bariatric surgery and lifestyle intervention. Methods: We recruited 79 participants who were assigned to three groups: bariatric surgery (BS group n=27), lifestyle intervention (LS group, n=22), and waitlist control (C group n=30). For all participants, electrogastrography, inflammatory cytokines, gastric hormones analysis, body composition analysis, energy expenditure, and dietary assessment were done at baseline and at 6 months.

Interventions

PROCEDURESleeve gastrectomy

laparoscopic sleeve gastrectomy was done under general anesthesia by the same surgeon in the SBAHC. Routine preoperative, and postoperative care (including early post-operative dietary management) were done. Baseline assessment was taken within the last week before the surgery during the preoperative preparation and the final assessment was recorded 6 months after the surgery date.

DIETARY_SUPPLEMENTLifestyle intervention

balanced 500 to 1000-calorie-deficit diet, personalized physical activity plan, and customized behavioral modification

Design outcomes

Primary

MeasureTime frameDescription
Gastric myoelectric activity6 monthsThe gastric myoelectric activity was measured in fasting (for 10 mins) and post-prandial state (for 30 mins) using a multichannel electrogastrography (EGG) with a water load satiety test
Inflammatory changes6 monthsSerum levels of inflammatory markers involving interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and monocyte chemoattractant protein (MCP-1),
Body composition measurement6 MONTHSBody composition was analyzed via a multi-Frequency segmental bioelectric impedance analysis monitor
Resting Energy Expenditure6 MONTHSResting metabolic rate (RMR) was measured by the automated metabolic cart indirect calorimetry (IC) using a standard canopy hood
hormonal analysis6 Monthsserum levels of ghrelin, gastrin, and irisin (ELISA kits MyBiosource, San Diego, CA, USA; Catalog numbers: MBS2700428, MBS264399, MBS2600406, respectively).
