Connecting Our Gut Feeling and How Our Gut Feels: The Role of Well-being Attributes in Irritable Bowel Syndrome

BACKGROUND/AIMS: There is a close relationship between the mind and gut in the pathogenesis of functional bowel disorders. Common psychological disturbances such as depression and anxiety are not uncommon in those with irritable bowel syndrome (IBS). There is little research investigating the role of positive psychology and gastrointestinal (GI) conditions. In this pilot study we investigated the well-being attributes in those with and without IBS. METHODS: We used an anonymous online survey and recruited 416 study subjects using social media as the main method of recruitment. We gathered demographic information, GI symptoms, history of mental health issues such as anxiety and depression, assessed several well-being attributes, and finally assessed subjective well-being. We hypothesized that those with GI symptoms and IBS have lower scores in their well-being attributes compared to healthy controls. RESULTS: We observed that a history of anxiety and depression is significantly associated with GI symptoms and IBS. In addition, sense of subjective well-being and several well-being attributes are negatively associated with GI symptoms and/or IBS. Of interest, the household income showed a negative correlation with the prevalence of GI symptoms and IBS. CONCLUSIONS: Subjective well-being, and several well-being attributes that contribute to the sense of overall contentment, are negatively associated with GI symptoms and IBS. The link between subjective well-being, and GI symptoms and IBS are independent of anxiety and depression. Well-being attributes and sense of subjective well-being may be a contributory factor in clinical expression of GI symptoms or IBS consistent with the biopsychosocial model of the disease.

Addition of Endoscopic Ultrasound (EUS)-Guided Fine Needle Aspiration and On-Site Cytology to EUS-Guided Fine Needle Biopsy Increases Procedure Time but Not Diagnostic Accuracy

BACKGROUND/AIMS: Although the diagnostic accuracy of endoscopic ultrasound with fine needle aspiration (EUS-FNA) in pancreas adenocarcinoma is high, endoscopic ultrasound with fine needle biopsy (EUS-FNB) is often required in other lesions; in these cases, it may be possible to forgo initial EUS-FNA and rapid on-site cytology evaluation (ROSE). The aim of this study was to compare the diagnostic accuracy of EUS-FNB alone (EUS-FNB group) with a conventional sampling algorithm of EUS-FNA with ROSE followed by EUS-FNB (EUS-FNA/B group) in nonpancreas adenocarcinoma lesions. METHODS: Retrospective cohort study of subjects who underwent EUS sampling of nonpancreatic adenocarcinoma lesions between February 2011 and May 2013. RESULTS: Over the study period, there were 43 lesions biopsied in 41 unique patients in the EUS-FNB group and 53 patients in the EUS-FNA/B group. Overall diagnostic accuracy was similar between the EUS-FNB and EUS-FNA/B groups (83.7% vs. 84.9%; p=1.0). In the subgroup of subepithelial mass lesions, diagnostic accuracy remained similar in the EUS-FNB and EUS-FNA/B groups (81.0% and 70.6%; p=0.7). EUS-FNB procedures were significantly shorter than those in the EUS-FNA/B group (58.4 minutes vs. 73.5 minutes; p<0.0001). CONCLUSIONS: EUS-FNB without on-site cytology provides a high diagnostic accuracy in nonpancreas adenocarcinoma lesions. There appears to be no additive benefit with initial EUS-FNA but this requires further study in a prospective study.
