Endoscopic risk factors to inform early detection of gastric cancer after eradication: Meta-analysis and systematic review.

Objectives: eradication reduces but cannot eliminate the risk of gastric cancer (GC). The prevalence of post-eradication GC has been rising. Characterization of the endoscopic findings of post-eradication GC may facilitate its early detection.

Brain activity during a public-speaking situation in virtual reality in patients with irritable bowel syndrome and functional dyspepsia.

Background: Psychosocial stress plays a central role in the pathophysiology of disorders of gut-brain interactions (DGBI), including functional dyspepsia (FD) and irritable bowel syndrome (IBS). Brain activity during psychosocial stress in patients with DGBI has not been adequately investigated. In this prospective study, we aimed to explore brain activity during psychosocial stress in patients with DGBI.

Effects of Medication Period and Gastrin Levels on Endoscopic Gastric Mucosal Changes in Long-Term Proton Pump Inhibitor Users.

: Proton pump inhibitor (PPI) use has increased worldwide, including in continuous and longer-term users. Recent reports highlight PPI-related endoscopic gastric mucosal changes, including fundic gland polyps, hyperplastic polyps, multiple white and flat elevated lesions, cracked and cobblestone-like mucosa (CCLM), and black spots. PPI use elevates gastrin levels because of acid inhibition, and hypergastrinemia might be relevant to these findings.

Contrast-enhanced ultrasonography combined with superb microvascular imaging for preoperative diagnosis of sporadic intra-abdominal desmoid-type fibromatosis: A case report.

We herein report a case of sporadic intra-abdominal desmoid-type fibromatosis in which contrast-enhanced ultrasonography (US) combined with superb microvascular imaging (SMI) was useful for preoperative diagnosis. 18-Fluorodeoxyglucose positron emission tomography performed for systematic screening for lung cancer revealed an abnormal accumulation in the abdominal cavity. Transabdominal US showed a tumor with a mixture of hypoechoic and hyperechoic areas.

Diagnostic performance of linked color imaging for gastric cancer by Helicobacter pylori infection status: A subanalysis of the large-scale, multicenter randomized controlled trial LCI-FIND.

Background: Linked color imaging (LCI) is a new image enhancement technology that facilitates the recognition of subtle differences in mucosal color. In the large-scale, multicenter randomized controlled trial LCI-FIND, LCI demonstrated good diagnostic performance for the detection of tumor lesions in the upper gastrointestinal tract. The aim of the present study was to exploratively evaluate the diagnostic performance of LCI according to H.

Different Food Preferences in Patients with Gastrointestinal Disorders.

Objective Gastrointestinal (GI) disorders such as functional dyspepsia (FD), irritable bowel syndrome (IBS), gastroesophageal reflux disease (GERD), and inflammatory bowel disease (IBD) can exhibit overlapping GI symptoms, including abdominal pain and alterations in bowel habits. The symptoms of GI disorders are commonly considered to be triggered and exacerbated by fatty food intake. Therefore, this study aimed to compare the food preferences of patients with GI disorders.

A Study of the Risk Factors for 402 Patients with Esophageal Squamous Cell Carcinoma - A Retrospective Comparison with Health Checkup Participants.

Objective Esophageal cancer is a gastrointestinal cancer with a poor prognosis. However, it is curable and can be treated endoscopically if it is detected at an early stage. The objective of this study was to identify the factors that contribute to early detection.

Appendiceal mucocele pathologically classified as appendiceal epithelial hyperplasia and preoperatively diagnosed by contrast-enhanced ultrasonography: A case report.

We report a patient with a mucocele with diffuse wall thickening diagnosed by transabdominal ultrasonography and contrast-enhanced ultrasonography. Transabdominal ultrasonography showed diffuse thickening of the entire appendix wall and an anechoic area that appeared to be fluid collected throughout the appendix lumen. However, the "onion skin sign" was not detected.

Mach-Zehnder interferometric engineering in silicon optical modulators: towards extrinsic OMA enhancement.

The realization of a high dynamic extinction ratio (ER) and optical modulation amplitude (OMA) while keeping the optical and radio-frequency (RF) signal losses low is a major issue for carrier-depletion Mach-Zehnder (MZ) silicon optical modulators. However, there is still room to improve modulator performance by applying the information gained from recent advanced testing technology to the modulator design. In this study, the extrinsic OMA (E-OMA) enhancement effect, which was discovered through the evaluation process and by revisiting the physics of the MZ interferometer (MZI), is investigated.

Progressive Multifocal Leukoencephalopathy Initially Suspected As Brain Relapse From Classical Hodgkin's Lymphoma.

HIV-negative progressive multifocal leukoencephalopathy (PML) has a poor prognosis due to a lack of standard treatment. Herein, we report a patient with HIV-negative PML which occurred after the treatment for classical Hodgkin's lymphoma (CHL). A 71-year-old male patient was admitted to our hospital due to various neurological symptoms, including memory disturbance, dysgraphia, ataxia, and ideomotor apraxia, at 16 months after high-dose salvage chemotherapy with autologous peripheral blood stem cell transplantation (PBSCT) for primary treatment-refractory CHL.

Brain activity in response to food images in patients with irritable bowel syndrome and functional dyspepsia.

Background: Functional dyspepsia (FD) and irritable bowel syndrome (IBS) are caused and exacerbated by consumption of fatty foods. However, no study has evaluated brain activity in response to food images in patients with disorders of gut-brain interaction (DGBI). This study aimed to compare food preference and brain activity when viewing food images between patients with DGBI and healthy controls.

Increase in the prevalence of follicular regulatory T cells correlates with clinical efficacy of sublingual immunotherapy with house dust mites.

Background: Allergic rhinitis (AR) impairs quality of life and affects nearly 40% of the Japanese population. Sublingual immunotherapy (SLIT) is the disease-modifying treatment for AR, but requires the selection of a biomarker associate with clinical efficacy in patients with AR who are treated with SLIT. The present study sought to examine objective biomarkers used for assessing the clinical efficacy of SLIT.

Intensity-modulated radiation therapy with the central shielding technique for patients with uterine cervical cancer†.

We aimed to examine outcomes and toxicities of intensity-modulated radiation therapy (IMRT) with the central shielding (CS) technique for patients with uterine cervical cancer. This retrospective study included 54 patients with International Federation of Gynecology and Obstetrics IB-IVA cancer. Whole pelvic radiotherapy or extended-field radiotherapy were performed at the dose of 50.

Development and acceptability of a decision aid for anxiety disorder considering discontinuation of benzodiazepine anxiolytic.

Aim: We aimed to develop a decision aid (DA) for individuals with anxiety disorders who consider tapering benzodiazepine (BZD) anxiolytics, and if tapering, tapering BZD anxiolytics with or without cognitive behavioral therapy (CBT) for anxiety. We also assessed its acceptability among stakeholders.

Methods: First, we conducted a literature review regarding anxiety disorders to determine treatment options.

A Case of Autoimmune Gastritis and Hepatitis with Enlarging Gastric Polyps after Reducing the Dose of Prednisolone.

Autoimmune gastritis is immune-mediated gastritis that destroys the oxyntic mucosa. Autoimmune hepatitis is an inflammatory liver disease caused by an autoimmune reaction. These diseases share similar pathogeneses as organ-specific autoimmune disorders; however, cases involving both diseases are quite rare and scarcely reported.

Clinical characteristics and long-term prognosis of type 1 gastric neuroendocrine tumors in a large Japanese national cohort.

Objectives: Optimal management of type 1 gastric neuroendocrine tumors (T1-GNETs) remains unknown, with few reports on their long-term prognosis. This study investigated the clinical characteristics and long-term prognosis of T1-GNETs.

Methods: We reviewed the medical records of patients diagnosed with T1-GNET during 1991-2019 at 40 institutions in Japan.

Differences between patients with inpatient-onset and outpatient-onset acute lower gastrointestinal bleeding: An observational study.

Background And Aim: The clinical severity and course of acute lower gastrointestinal bleeding (ALGIB) are believed to differ between inpatient-onset and outpatient-onset cases, but no reports have investigated these issues in detail. We aimed to evaluate the clinical differences between inpatient-onset and outpatient-onset ALGIB.
