Digestion and intestinal absorption allow the body to sustain itself and are the emblematic functions of the bowel.On the flip side,functions also arise from its role as an interface with the environment.Indeed,the gut houses microorganisms,collectively known as the gut microbiota,which interact with the host,and is the site of complex immune activities.Its role in human pathology is complex and scientific evidence is progressively elucidating the functions of the gut,especially regarding the pathogenesis of chronic intestinal diseases and inflammatory conditions affecting various organs and systems.This editorial aims to highlight and relate the factors involved in the pathogenesis of intestinal and systemic inflammation. 展开更多

Chronic gastritis(CG)is a widespread and frequent disease,mainly caused by Helicobacter pylori infection,which is associated with an increased risk of gastric cancer.Virtual chromoendoscopy improves the endoscopic diagnostic efficacy,which is essential to establish the most appropriate therapy and to enable cancer prevention.Artificial intelligence provides algorithms for the diagnosis of gastritis and,in particular,early gastric cancer,but it is not yet used in practice.Thus,technological innovation,through image resolution and processing,optimizes the diagnosis and management of CG and gastric cancer.The endoscopic Kyoto classification of gastritis improves the diagnosis and management of this disease,but through the analysis of the most recent literature,new algorithms can be proposed. 展开更多

BACKGROUND Few studies have examined intestinal motility disorders, which are disabling conditions associated with chronic functional constipation, whose pathogenesis is actually not well-defined.AIM To investigate the relationship between serum 25-hydroxyvitamin D levels and functional chronic constipation associated to intestinal motility disorders.METHODS We performed a prospective case-control study, from May-June to November2017. Glucose/lactulose breath tests, radiopaque markers(multiple capsule techniques) and wireless motility capsule analysis were used to assess colonicand oro-cecal transit time, after excluding small-intestinal bacterial overgrowth condition. Then, we measured 25-hydroxyvitamin D levels in patients with intestinal motility disorders and we further evaluated the influence of intestinal motility disorders on psychological symptoms/quality of life using validated questionnaires, the Irritable Bowel Syndrome Quality of life(IBS-QOL), the Short Form Health Survey 12, and the Hospital Anxiety and Depression Scale 14(HADS-14 A and HADS-14 D).RESULTS We enrolled 86 patients with chronic functional constipation associated to intestinal motility disorders and 86 matched healthy subjects. Patients with intestinal motility disorders had lower 25-hydroxyvitamin D levels(P < 0.001), and they showed a significant impairment of all health-related quality of life and psychological tests(IBS-QOL, Short Form Health Survey 12-Physical Component Summary, Short Form Health Survey 12-Mental Component Summary, HADS-14 A and HADS-14 D), as compared to the control group(P < 0.001), which significantly correlated with low vitamin D levels(r =-0.57, P < 0.001; r = 0.21, P = 0.01; r =-0.48, P < 0.001; r =-0.57, P < 0.001; r =-0.29, P < 0.001, respectively). At multivariate analysis vitamin D low levels remained a significant independent risk factor for the occurrence of intestinal motility disorder(odds ratio = 1.19; 95% confidence interval: 1.14-1.26, P < 0.001).CONCLUSION Vitamin D deficiency, anxiety and depression symptoms are commonly associated with chronic functional constipation induced by intestinal motility disorders. Vitamin D serum levels should be routinely measured in these patients. 展开更多

Gastric cancer is widespread globally,and disease diagnosis is accompanied by high mortality and morbidity rates.However,prognoses and survivability have improved following implementation of surveillance and screening programs,which have led to earlier diagnoses.Indeed,early diagnosis itself supports increased surgical curability,which is the main treatment goal and guides therapeutic choice.The most recent Japanese guidelines for endoscopic submucosal dissection and endoscopic mucosal resection for early gastric cancer consider the degree of endoscopic curability in relation to the characteristics of the gastric lesions.In clinical practice,the management approach for both prevention and treatment should be similar to that of colon lesions;however,unlike the established practices for colorectal cancer,the diagnostic and therapeutic pathways are not shared nor widespread for gastric cancer.Ultimately,this negatively impacts the opportunity to perform an endoscopic resection with curative intent. 展开更多

BACKGROUND Helicobacter pylori(H.pylori)infection has been associated with a long-term risk of precancerous gastric conditions(PGC)even after H.pylori eradication.AIM To investigate the efficacy of High-Resolution White-Light Endoscopy with Narrow-Band Imaging in detecting PGC,before/after H.pylori eradication.METHODS We studied 85 consecutive patients with H.pylori-related gastritis with/without PGC before and 6 mo after proven H.pylori eradication.Kimura-Takemoto modified and endoscopic grading of gastric intestinal metaplasia classifications,were applied to assess the endoscopic extension of atrophy and intestinal metaplasia.The histological result was considered to be the gold standard.The Sydney System,the Operative-Link on Gastritis-Assessment,and the Operative-Link on Gastric-Intestinal Metaplasia were used for defining histological gastritis,atrophy and intestinal metaplasia,whereas dysplasia was graded according to World Health Organization classification.Serum anti-parietal cell antibody and anti-intrinsic factor were measured when autoimmune atrophic gastritis was suspected.RESULTS After H.pylori eradication histological signs of mononuclear/polymorphonuclear cell infiltration and Mucosal Associated Lymphoid Tissue-hyperplasia,disappeared or decreased in 100%and 96.5%of patients respectively,whereas the Operative-Link on Gastritis-Assessment and Operative-Link on Gastric-Intestinal Metaplasia stages did not change.Low-Grade Dysplasia prevalence was similar on random biopsies before and after H.pylori eradication(17.6%vs 10.6%,P=0.19),but increased in patients with visible lesions(0%vs 22.4%,P<0.0001).At a multivariate analysis,the probability for detecting dysplasia after resolution of H.pylori-related active inflammation was higher in patients with regression or reduction of Mucosal Associated Lymphoid Tissue hyperplasia,greater alcohol consumption,and anti-parietal cell antibody and/or anti-intrinsic factor positivity[odds ratio(OR)=3.88,95%confidence interval(CI):1.31-11.49,P=0.01;OR=3.10,95%CI:1.05-9.12,P=0.04 and OR=5.47,95%CI:1.33-22.39,P<0.04,respectively].CONCLUSION High-Resolution White-Light Endoscopy with Narrow-Band Imaging allows an accurate diagnosis of Low-Grade Dysplasia on visible lesions after regression of H.pylori-induced chronic gastritis.Patients with an overlap between autoimmune/H.pylori-induced gastritis may require more extensive gastric mapping. 展开更多

Gastric cancer(GC)is a major cancer worldwide,with high mortality and morbidity.Endoscopy,important for the early detection of GC,requires trained skills,high-quality technologies,surveillance and screening programs.Early diagnosis allows a better prognosis,through surgical or curative endoscopic therapy.Magnified endoscopy with virtual chromoendoscopy remarkably improve the detection of early gastric cancer(EGC)when endoscopy is performed by expert endoscopists.Artificial intelligence(AI)has also been introduced to GC diagnostics to increase diagnostic efficiency.AI improves the early detection of gastric lesions because it supports the non-expert and experienced endoscopist in defining the margins of the tumor and the depth of infiltration.AI increases the detection rate of EGC,reduces the rate of missing tumors,and characterizes EGCs,allowing clinicians to make the best therapeutic decision,that is,one that ensures curability.AI has had a remarkable evolution in medicine in recent years,moving from the research phase to clinical practice.In addition,the diagnosis of GC has markedly progressed.We predict that AI will allow great evolution in the diagnosis and treatment of EGC by overcoming the variability in performance that is currently a limitation of chromoendoscopy. 展开更多
