Background: Previous research has shown anxiety to relate to gastrointestinal (GI) symptoms in endurance athletes, but it remains unclear whether competition-related fueling is impacted by anxiety. This study examined whether general anxiety, pre-race anxiety, and visceral sensitivity were associated with nutritional intake before and during endurance running races.
Methods: A total of 149 (86 female, 63 male) runners participated in this cross-sectional survey study. Assessments, which were carried out at a median of eight hours after races finished, included the State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA)-Trait, Visceral Sensitivity Index (VSI), perceived pre-race anxiety (0-10), during-race GI symptoms (total, upper, and lower), and intakes of energy, macronutrients, fluid, and caffeine for the pre-race period (4 h before) and during races. Spearman's correlations were used to examine associations between variables. A two-sided P value ≤0.01 was used as the threshold for significance.
Results: Median race durations were 139.5 and 126.9 min for women and men, respectively. VSI scores were positively correlated with total during-race GI symptoms, while STICSA-Trait scores were positively correlated with total and upper during-race GI symptoms (ρ=0.22-0.25; P<0.01). No significant correlations were observed between measures of anxiety/visceral sensitivity and nutrient intakes before or during races.
Conclusions: In a sample of primarily recreational runners, greater anxiety and visceral sensitivity did not translate to lower intakes of energy, macronutrients, fluid, etc. around competition. Further work is needed in other settings, especially with high-level athletes, to understand the impact of competition anxiety on fueling choices.

Cisplatin, a chemotherapeutic drug, is known for causing gastrointestinal disorders and neuropathic pain, but its impact on visceral sensitivity is unclear. Monosodium glutamate (MSG) has been shown to improve gastrointestinal dysmotility and neuropathic pain induced by cisplatin in rats. This study aimed to determine if repeated cisplatin treatment alters visceral sensitivity and whether dietary MSG can prevent these changes.

Hepatocellular carcinoma (HCC) is the sixth most common cancer and the third leading cause of cancer-related death worldwide, with no precise method for early detection. Circulating tumor cells (CTCs) expressing the dynamic polarity of the cytoskeletal membrane protein, ezrin, have been proposed to play a crucial role in tumor progression and metastasis. This study investigated the diagnostic and prognostic potential of polarized circulating tumor cells (p-CTCs) in HCC patients.

Background And Aims: The enteric nervous system independently controls gastrointestinal function including motility, which is primarily mediated by the myenteric plexus, therefore also playing a crucial role in functional intestinal disorders. Live recordings from human myenteric neurons proved to be challenging due to technical difficulties. Using the neuroimaging technique, we are able to record human colonic myenteric neuronal activity and investigate their functional properties in a large cohort of patients.

Corticosteroid binding globulin (CBG; SERPINA6) binds >85% of circulating glucocorticoids but its influence on their metabolic actions is unproven. Targeted proteolytic cleavage of CBG by neutrophil elastase (NE; ELANE) significantly reduces CBG binding affinity, potentially increasing 'free' glucocorticoid levels at sites of inflammation. NE is inhibited by alpha-1-antitrypsin (AAT; SERPINA1).

Among the various factors implicated in the pathogenesis of gastroesophageal reflux disease (GERD), visceral hypersensitivity and mucosal resistance have been recently re-evaluated in relation to the increasing phenomenon of proton pump inhibitor failure, particularly in patients with nonerosive reflux disease (NERD). Intensive research has allowed us to understand that noxious substances contained in the refluxate are able to interact with esophageal epithelium and to induce the elicitation of symptoms. The frequent evidence of microscopic esophagitis able to increase the permeability of the mucosa, the proximity of sensory afferent nerve fibers to the esophageal lumen favoring the higher sensitivity to noxious substances and the possible activation of inflammatory pathways interacting with sensory nerve endings are pathophysiological alterations confirming that mucosal resistance is impaired in GERD patients.
