Fatty liver disease (FLD) including non-alcoholic fatty (NAFLD), a rapidly emerging and widely recognized today, is regarded as hepatic manifestation of metabolic syndrome. Helicobacter pylori, one the most common pathogens worldwide, has been reported to be associated with syndrome, but whether there direct association FLD yet unclear. The aim this study was clarify NAFLD causative background factors pylori infection.This cross-sectional Japanese adults who received medical checkups at...

Background Despite the marked increase of diverticulosis, its risk factors have not been adequately elucidated. We therefore aim to identify significantly associated with diverticulosis. also investigate present state diverticulosis in Japan.

Gastroesophageal reflux disease (GERD) is a very common disorder worldwide, comprised of esophagitis (RE) and non-erosive (NERD). As more than half GERD patients are classified into the NERD group, precise evaluation bothersome epigastric symptoms essential. Nevertheless, compared with many reports targeting endoscopic esophagitis, large-scale studies focusing on have been scarce. To elucidate lifestyle factors affecting symptoms, 19,864 healthy adults in Japan were analyzed. Sub-analyses...

To clarify the effectiveness of second-look endoscopy (SLE) at preventing bleeding after gastric endoscopic submucosal dissection (ESD).A multicentre prospective randomised controlled non-inferiority trial was conducted five referral institutions across Japan. Patients with a solitary neoplasm were enrolled. Exclusion criteria previous oesophagogastric surgery or radiation therapy; perforation and administration antithrombotics, steroids non-steroidal anti-inflammatory drugs. assigned to SLE...

Background Despite the high prevalence of gastroesophageal reflux disease (GERD), its risk factors are still a subject controversy. This is probably due to inadequate distinction between esophagitis (RE) and non-erosive (NERD), also evaluation adjacent stomach. Our aim therefore define background RE NERD independently, based on Helicobacter pylori infection gastric atrophy. Methods We analyzed 10,837 healthy Japanese subjects (6,332 men 4,505 women, aged 20–87 years) who underwent upper...

Background Several previous studies have suggested that Helicobacter pylori (H. pylori) infection affects the serum lipid profile. However, it remains controversial and mechanism has not been elucidated. The purpose of this study is to use an epidemiological perspective evaluate association between H. Methods Multivariate analysis was performed using data profile, status pylori, fitness/lifestyle habits, various subjects’ characteristics which were derived from 15,679 generally healthy...

Abstract Poly‐ L ‐lactide (PLLA) plates, 20 × 10 1 mm in size, with flat surfaces, were implanted into 50 young male Wistar rats subcutaneously, and the incidence of tumors for 2 years under specific pathogen‐free (SPF) conditions was evaluated. Tumors arose 22 (at implant sites 20, distant from implantation site 2). As a control, plates medical‐grade polyethylene same shape rats. appeared 23 these (21 at ectopically). In 30 given sham operations, no year observation period. Histologically,...

Helicobacter pylori eradication is expected to significantly change the prevalence of Barrett's esophagus (BE). However, few reports on this relationship exist. We analyzed risk factors BE using current consensus length considering H. infection status.We 10,122 individuals (5,962 men; mean age = 52.9 ± 9.9 years) who had undergone esophagogastroduodenoscopy as part a medical checkup. Correlations among including infectious status, endoscopic findings, and ≥1 cm were analyzed.Prevalence BE,...

We sought to investigate cusp size limitations for valve repair in patients with aortic regurgitation (AR).Preoperative computed tomography was performed 105 patients. Cusp geometric height (GH) and annulus were measured. Mean patient age 60.7 ± 13.7 years. GH of 3 cusps used the analysis. Annulus mismatch graded using predicted coaptation length. Patients categorized by mean into group S (GH <16 mm; n = 35) or L ≥16 70).Preoperative 17.1 2.3 mm. body significantly correlated (r 0.61)....
