Background Obese patients (Ob) with a binge eating disorders (BED) behavior pattern have a higher prevalence of postprandial distress syndrome (PDS) compared to Ob without a BED behavior pattern, while an increase of PDS has been described in Ob after sleeve gastrectomy (SG). Hedonic response to a meal is dissociable from satiation in healthy subjects. Anhedonia is the lowered ability to experience pleasure. There are no studies investigating the presence of anhedonia in Ob with and without SG and its relationship to PDS symptoms. Aim To assess the relationship among anhedonia, BED and upper gastrointestinal symptoms in two group of morbidly Ob with and without SG. Methods Eighty-one Ob without SG, 45 Ob with SG and 55 healthy controls (HC) were studied. All subjects fulfilled the binge eating scale (BES) to investigate BED, the validated 14 items Snaith-Hamilton pleasure scale (SHAPS) to assess Anhedonia as well as the Beck Depression Inventory-II (BDI II) and State Trait Anxiety Inventory (STAI) questionnaignosis of FD. SHAPS mean scores and the prevalence of anhedonia did not differ among the two groups (18.2 vs 8.1%, P = 0.2). Fifty-four percent of Ob with SG achieved surgical success excess weight loss > 50%. Excess weight loss was negatively related to SHAPS total mean scores [adjusted B -7. 099 (95%CI -13.91 to -0.29), P = 0.04]. Conclusion Ob without SG showed a higher prevalence of PDS, mood disorders and anxiety when positive for BE behavior compared to those negative for BE behavior, whereas no differences were found in SHAPS score. Ob with SG showed a higher prevalence of PDS compared to Ob without SG. Concerning psychological aspect, BED and depression are less frequent in the Ob with SG, while both state and trait anxiety are significantly higher. Moreover, the more an Ob with SG is anhedonic, less surgical success was achieved.Background Persistent Helicobacter pylori (H. pylori) infection causes chronic inflammation, atrophy of the gastric mucosa, and a high risk of developing gastric cancer. In recent years, awareness of eradication therapy has increased in Japan. As H. pylori infections decrease, the proportion of gastric cancers arising from H. pylori uninfected gastric mucosa will increase. The emergence of gastric cancer arising in H. pylori uninfected patients though rarely reported, is a concern to be addressed and needs elucidation of its clinicopathological features. Aim To evaluate the clinicopathological features of early gastric cancer in H. pylori-uninfected patients. Methods A total of 2462 patients with 3375 instances of early gastric cancers that were treated by endoscopic submucosal dissection were enrolled in our study between May 2000 and September 2019. Of these, 30 lesions in 30 patients were diagnosed as H. pylori-uninfected gastric cancer (HpUIGC). We defined a patient as H. pylori-uninfected using the folloerentiated type.The HpUIGC lesions were classified into fundic gland type adenocarcinoma (7 cases), foveolar type well-differentiated adenocarcinoma (8 cases), intestinal phenotype adenocarcinoma (7 cases), and pure signet-ring cell carcinoma (8 cases). Among 30 HpUIGCs, 24 lesions (80%) were limited to the mucosa; wherein, the remaining 6 lesions showed submucosal invasion. One of the submucosal invasive lesions showed more than 500 μm invasion. The mucin phenotype analysis identified 7 HpUIGC with intestinal phenotype and 23 with gastric phenotype. Conclusion We elucidated the clinicopathological characteristics of HpUIGC, revealing recognition not only undifferentiated-type but also differentiated-type. In addition, intestinal phenotype tumors were also observed and could be an important tip.Background Previous evidence has implied that obesity is an independent risk factor for developing cancer. Being closely related to obesity, type 2 diabetes mellitus provides a suitable environment for the formation and metastasis of tumors through multiple pathways. Although bariatric surgeries are effective in preventing and lowering the risk of various types of cancer, the underlying mechanisms of this effect are not clearly elucidated. Aim To uncover the role and effect of sleeve gastrectomy (SG) in preventing lung cancer in obese and diabetic rats. Methods SG was performed on obese and diabetic Wistar rats, and the postoperative transcriptional and translational alterations of the endothelin-1 (ET-1) axis in the lungs were compared to sham-operated obese and diabetic rats and age-matched healthy controls to assess the improvements in endothelial function and risk of developing lung cancer at the postoperative 4th, 8th, and 12th weeks. The risk was also evaluated using nuclear phosphorylation of H2A histone family member X as a marker of DNA damage (double-strand break). selleck kinase inhibitor Results Compared to obese and diabetic sham-operated rats, SG brought a significant reduction to body weight, food intake, and fasting blood glucose while improving oral glucose tolerance and insulin sensitivity. In addition, ameliorated levels of gene and protein expression in the ET-1 axis as well as reduced DNA damage indicated improved endothelial function and a lower risk of developing lung cancer after the surgery. Conclusion Apart from eliminating metabolic disorders, SG improves endothelial function and plays a protective role in preventing lung cancer via normalized ET-1 axis and reduced DNA damage.Background Since it is currently not possible to eradicate hepatitis B virus (HBV) infection with existing treatments, research continues to uncover new therapeutic strategies. HBV core protein, encoded by the HBV core gene (HBC), intervenes in both structural and functional processes, and is a key protein in the HBV life cycle. For this reason, both the protein and the gene could be valuable targets for new therapeutic and diagnostic strategies. Moreover, alterations in the protein sequence could serve as potential markers of disease progression. Aim To detect, by next-generation sequencing, HBC hyper-conserved regions that could potentially be prognostic factors and targets for new therapies. Methods Thirty-eight of 45 patients with chronic HBV initially selected were included and grouped according to liver disease stage [chronic hepatitis B infection without liver damage (CHB, n = 16), liver cirrhosis (LC, n = 5), and hepatocellular carcinoma (HCC, n = 17)]. HBV DNA was extracted from patients' plasma. A region between nucleotide (nt) 1863 and 2483, which includes HBC, was amplified and analyzed by next-generation sequencing (Illumina MiSeq platform).
