Background: The aim of this study was to investigate the visceral sensation to gastric stimulation and its correlation with the stimulation-induced alterations in gastric accommodation and gastric emptying.
Methods: The study was performed in 12 healthy human controls. Gastric stimulation was performed using bipolar electrodes attached to the mucosa of the distal stomach under endoscopy. Experiments were conducted on 3 consecutive days to investigate the effects of gastric stimulation with various parameters on visceral sensation, maximum intake of water and gastric emptying of solids.
Results: 1) The stimulation energy was 265.6 +/- 134.9 smA 2 for the first sensation and 2,020.0 +/- 865.1 smA2 for the maximum tolerance, and there was a large variation among the subjects; 2) Gastric stimulation with stimulation energy less than 50% of that required to induce the first sensation significantly reduced the maximum intake of water and delayed gastric emptying of solids without inducing symptoms; 3) The stimulation energy of the first sensation was significantly correlated with the stimulation-induced reduction in water intake (r=-0.80, P=0.02) and the stimulation-induced prolongation of gastric emptying (r=-0.78, P=0.003). That is, the inhibitory effects of gastric stimulation were more obvious in those subjects who were viscerally more sensitive to gastric stimulation.
Conclusions: Gastric stimulation via the distal stomach reduces gastric accommodation and delays gastric emptying. These inhibitory effects are correlated with the visceral sensitivity of the individual to gastric stimulation. It is worthy to further investigate whether the outcome of the implantable gastric stimulation (IGS) therapy for obesity may be predicted from the visceral sensitivity of the patient to temporary gastric stimulation using endoscopically placed mucosal electrodes.

Background: Immune checkpoint inhibitors (ICIs) have moved to the frontline in recent years to manage upper gastrointestinal (UGI) tumors, such as esophageal and gastric cancers. This retrospective review sheds light on real-world data on ICI-treated UGI tumors to identify risk factors (clinical and pathological) impacting the outcome other than traditional biomarkers (programmed cell death ligand 1 (PD-L1) or microsatellite instability status).
Methods: Patients with UGI tumors who received at least one dose of ICI for stage IV or recurrent disease between January 1, 2015, and July 31, 2021, at The Ohio State University were included in the study.

The microenvironment tends to be immunosuppressive during tumor growth and proliferation. Immunotherapy has attracted much attention because of its ability to activate tumor-specific immune responses for tumor killing. The cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is an innate immune pathway that activates antitumor immunity by producing type I interferons.

Type 2 diabetes (T2D), the most common form, is marked by insulin resistance and β-cell failure. β-cell dysfunction under high-glucose-high-lipid (HG-HL) conditions is a key contributor to the progression of T2D. This study evaluates the comparative effects of 10 nM semaglutide, 10 nM tirzepatide, and 1 mM metformin, both alone and in combination, on INS-1 β-cell maintenance and function under HG-HL conditions.

Weaning in piglets presents significant physiological and immunological challenges, including gut dysbiosis and increased susceptibility to post-weaning diarrhoea (PWD). Abrupt dietary, environmental, and social changes during this period disrupt the intestinal barrier and microbiota, often necessitating antimicrobial use. Sustainable dietary strategies are critical to addressing these issues while reducing reliance on antimicrobials.
