Sex differences in the reactivity of gastric myoelectrical activity and heart rate variability as putative psychophysiological markers in human pain research.
Front Neurosci
December 2024
Department of Neurology, Center for Translational Neuro-and Behavioral Sciences (C-TNBS), University Hospital Essen, University of Duisburg-Essen, Essen, Germany.
Background: This study explored the potential of electrogastrography (EGG) and heart rate variability (HRV) as psychophysiological markers in experimental pain research related to the gut-brain axis. We investigated responses to the experience of pain from the visceral (rectal distension) and somatic (cutaneous heat) pain modalities, with a focus on elucidating sex differences in EGG and HRV responses.
Methods: In a sample of healthy volunteers (29 males, 43 females), EGG and ECG data were collected during a baseline and a pain phase.
Association of Dietary Intake with Interoception and Gastric Myoelectric Activity in Women with Binge Eating Disorder and Bulimia Nervosa.

Department of Community Health Sciences, College of Applied Medical Sciences, King Saud University, 11362 Riyadh, Saudi Arabia.
Background: Women with binge eating disorder (BED) and bulimia nervosa (BN) usually consume high-calorie meals with variable macro- and micronutrient compositions and have a disturbed perception of gastric fullness. The association of dietary intake with gastric interoception and gastric myoelectric activity (GMA) is poorly studied. This study examined the link between GMA/interoception and dietary intake in women with eating disorders (ED) compared to age/body mass index (BMI)-matched controls.

To investigate the characteristics of gastric electric rhythm in patients with obesity. Obese patients who were scheduled to undergo weight reduction surgery in Peking Union Medical College Hospital from January 2018 to February 2024 were prospectively included. According to body mass index (BMI), the patients were divided into mild-to-moderate obesity group (28 kg/m≤BMI<40 kg/m) and severe obesity group (BMI≥40 kg/m).

Department of Pediatrics, Universidad Nacional de Colombia, Carrera 30 # 45-03, Edificio 471, Oficina 111, Bogotá, Colombia.
Background: Gastroparesis is a delay in gastric emptying without mechanical obstruction, lacking a clear pathophysiological mechanism, but with multiple histological abnormalities including loss of interstitial cells of Cajal, which may alter slow waves. We can assess slow waves with electrogastrography.
Objectives: To determine the prevalence and range of abnormalities in gastric slow waves in adults with gastroparesis using electrogastrography.
Assessment of Gastric Remnant Activity, Symptoms, and Quality of Life Following Gastric Bypass.

Article Synopsis
- - The study investigated long-term complications in gastric bypass patients, such as nausea and abdominal pain, and their impact on quality of life (QoL), focusing on the residual stomach's activity.
- - Researchers used the Gastric Alimetry® System to assess the gastrointestinal function of patients 46.8 months after surgery, revealing significant post-meal symptoms and noticeably degraded gastric function compared to control groups.
- - Findings indicated that one-third of participants exhibited severe gastrointestinal symptoms and lower QoL, with the remnant stomach showing abnormal electrophysiology that was linked to diminished quality of life, though the study does not confirm a direct cause-and-effect relationship.
