Leucine-Rich Alpha-2 Glycoprotein Is Associated With Transmural Inflammation Assessed by Intestinal Ultrasound in Patients With Crohn's Disease.

Background: Intestinal ultrasound (IUS) is a non-invasive tool for evaluating transmural inflammation in Crohn's disease (CD). However, its utility is constrained by operator dependency and limited accessibility.

Aims: To explore the feasibility of serum biomarkers-specifically leucine-rich alpha-2 glycoprotein (LRG)-as an alternative to IUS for assessing transmural inflammation.

Effectiveness of a novel ex vivo training model for gastric endoscopic submucosal dissection training: a prospective observational study conducted at a single center in Japan.

Background/aims: The efficacy of endoscopic submucosal dissection (ESD) for early-stage gastric cancer is well established. However, its acquisition is challenging owing to its complexity. In Japan, G-Master is a novel ex vivo gastric ESD training model.

Real-World Data on the Effectiveness and Safety of Filgotinib for Ulcerative Colitis in Japanese Patients: A Single-Center Experience.

Introduction Filgotinib is a JAK-1 selective inhibitor approved for ulcerative colitis (UC) treatment in Japan. Its effectiveness has been confirmed but remains unknown in actual clinical practice. Therefore, we aimed to evaluate the effectiveness and safety of filgotinib and identify suitable patients in the Japanese population.

Early change in serum leucine-rich α-2-glycoprotein predicts clinical and endoscopic response in ulcerative colitis.

Background/aims: Leucine-rich α-2-glycoprotein (LRG) is a new serum biomarker reflecting the disease activity of ulcerative colitis (UC), but its change during the acute phase has not been enough investigated.

Methods: Patients with UC who initiated the induction therapy with steroid or advanced therapy (biologics or Janus kinase inhibitors) were prospectively enrolled. Associations of LRG, C-reactive protein (CRP) and fecal calprotectin (FC) at baseline, week 1, and week 8 with clinical remission at week 8 and subsequent endoscopic improvement within 1 year (Mayo endoscopic subscore of 0 or 1) were assessed.

A case of cytomegalovirus esophagitis difficult to distinguish from Crohn's disease exacerbation.

Patients with Crohn's disease are at higher risk of opportunistic infection, especially if treated with immunosuppressive therapy. Cytomegalovirus has been reported to cause ulcerated lesions mainly in the lower gastrointestinal tract of inflammatory bowel disease patients. We herein report a rare case of Crohn's disease complicated with cytomegalovirus esophagitis, which was difficult to distinguish from exacerbation of Crohn's disease.

Milan Ultrasound Criteria Predict Relapse of Ulcerative Colitis in Remission.

Introduction: Bowel ultrasound is a noninvasive alternative to endoscopy for assessing the disease activity of ulcerative colitis; however, it is unclear whether bowel ultrasound can predict subsequent relapse from remission.

Materials And Methods: A retrospective cohort study enrolled patients with ulcerative colitis who underwent bowel ultrasound between July 2018 and July 2021 during clinical remission (patient-reported outcome-2 ≤1 and no rectal bleeding) for at least 3 months and were followed up for 1 year. Ultrasonographic findings (bowel wall thickness, bowel wall flow, bowel wall stratification, and enlarged lymph nodes), Milan ultrasound criteria, Mayo endoscopic subscore, C-reactive protein, and fecal calprotectin levels and their association with subsequent clinical relapse were assessed.

A Novel Hemostatic Peptide Solution for Common Acute Gastrointestinal Bleeding Diseases: First Case Series Study on the Treatment Results of Endoscopic Hemostasis by Nonexpert Endoscopists.

Introduction: We investigated the hemostatic effect and safety of a hemostatic peptide solution for the treatment of gastrointestinal bleeding requiring emergency endoscopy.

Methods: We retrospectively examined the patient backgrounds, hemostatic results, and procedural safety in patients who were treated with a hemostatic peptide solution for hemostasis during emergency endoscopies for gastrointestinal bleeding. All hemostatic procedures were performed by nonexpert physicians with less than 10 years of endoscopic experience.

Optimal Use of Serum Leucine-Rich Alpha-2 Glycoprotein as a Biomarker for Small Bowel Lesions of Crohn's Disease.

Introduction: A large proportion of small bowel lesions in Crohn's disease (CD) may exist beyond the reach of ileocolonoscopy and there is no gold standard imaging modality to screen them, suggesting the need for optimal biomarkers. We aimed to compare the usefulness of C-reactive protein (CRP), faecal calprotectin (FC), and leucine-rich alpha-2 glycoprotein (LRG) in determining small bowel lesions of CD.

Methods: This was a cross-sectional observational study.

Multiple ulcerative colitis-associated aseptic abscesses successfully treated with infliximab: a case report.

Aseptic abscesses are rare extraintestinal manifestations of inflammatory bowel disease. Herein, we present the case of a 69-year-old female patient with ulcerative colitis in whom multiple aseptic abscesses were successfully treated with infliximab. Aseptic abscesses associated with ulcerative colitis are difficult to differentiate from infectious abscesses.

Usefulness of colestimide for diarrhea in postoperative Crohn's disease.

Background And Aim: Crohn's disease (CD) often causes intractable diarrhea after intestinal resection. Anion exchange resins have been reported to be effective in patients with bile acid diarrhea after distal ileectomy; furthermore, bile acid metabolism has been implicated in the pathogenesis of CD. Therefore, we aimed to examine the effectiveness of colestimide in the management of postoperative CD, and to compare its impact between patients with and those without ileocecal resection.

Evaluation of Safety-Related Outcomes of One-Segment and More-Than-One-Segment High-Level Hepatectomy in Hepatocellular Carcinoma Based on the Japanese Board Certification System.

Background: We evaluated the impact of the Japanese board certification system for expert surgeons (JBCSES) on complications and survival outcomes in hepatectomy for hepatocellular carcinoma.

Methods: The postoperative outcomes of 493 patients who underwent high-level liver surgery involving one-segment (OSeg) hepatectomy and more-than-one-segment (MOSeg) resection were compared before and after JBCSES establishment. After the establishment of the JBCSES, the patients' postoperative outcomes were compared using propensity score matching (PSM) to determine the influence of expert surgeons.

Natural capital evaluation in the FutureCity of Shimokawa, Northern Japan, based on forest economics.

We have pragmatically but accurately evaluated the natural capital of a small northern town, Shimokawa, Hokkaido, Japan. The key industries are forestry, wood manufacturing, and agriculture. From an environmental perspective, Shimokawa was nominated as a Japanese FutureCity.

A case of fulminant infection: Role of macroscopic examination of the serum and peripheral blood smears.

A 69-year-old man was brought to our hospital by ambulance with a fever. The translucent pink color of the serum sample suggested severe hemolysis. His blood pressure dropped rapidly, and he later suffered a cardiopulmonary arrest and died approximately 30 h after arriving at our hospital.

Objective: To elucidate the genetic background and genotype-phenotype correlations for epilepsy with myoclonic-atonic seizures, also known as myoclonic-astatic epilepsy (MAE) or Doose syndrome.

Methods: We collected clinical information and blood samples from 29 patients with MAE. We performed whole-exome sequencing for all except one MAE case in whom custom capture sequencing identified a variant.

[Thrombectomy for right atrial thrombosis complicating a pyogenic liver abscess].

Vascular complications from a liver abscess are rare but life-threatening. Herein, we report the case of a man in his 40s with a pyogenic hepatic abscess complicated by an inferior vena caval thrombus extending to the right atrium. His presenting complaint was a high fever.

Acceleration of carboxylesterase-mediated activation of irinotecan to SN-38 by serum from patients with end-stage kidney disease.

Purpose: Pharmacokinetics and pharmacodynamics of irinotecan have been reported to be altered in cancer patients with end-stage kidney disease (ESKD). Carboxylesterase (CES) has an important role in metabolism of irinotecan to its active metabolite, SN-38, in human liver. The purpose of the present study was to investigate whether CES activity was altered in ESKD patients.

A Host-Dependent Prognostic Model for Elderly Patients with Diffuse Large B-Cell Lymphoma.

Background: Decision-making models for elderly patients with diffuse large B-cell lymphoma (DLBCL) treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) are in great demand.

Patients And Methods: The Society of Lymphoma Treatment in Japan (SoLT-J), in collaboration with the West-Japan Hematology and Oncology Group (West-JHOG), collected and retrospectively analyzed the clinical records of ≥65-year-old patients with DLBCL treated with R-CHOP from 19 sites across Japan to build an algorithm that can stratify adherence to R-CHOP.

Results: A total of 836 patients with a median age of 74 years (range, 65-96 years) were analyzed.

A cyclin D1-negative mantle cell lymphoma with an IGL-CCND2 translocation that relapsed with blastoid morphology and aggressive clinical behavior.

Mantle cell lymphoma (MCL) is a B cell neoplasm characterized by cyclin D1 overexpression; its prognosis is poor, especially when it exhibits a blastoid morphology. Cyclin D1-negative MCL is rare, and its pathogenesis and progression remain unclear. Herein, we describe a cyclin D1-negative, cyclin D2-positive MCL with a CCND2 and immunoglobulin lambda light chain (IGL) translocation.

Negative impact of concurrent overexpression of MYC and BCL2 in patients with advanced diffuse large B-cell lymphoma treated with dose-intensified immunochemotherapy.

Co-expression of MYC and BCL2 proteins in diffuse large B-cell lymphoma (DLBCL), or 'double-expressor lymphoma' (DEL), results in poor patient prognosis, but the significance of DEL when aggressive treatments are applied remains uncertain. We performed a retrospective analysis of 40 patients with de novo DLBCL, who were categorized as being at high/high-intermediate risk according to the age-adjusted International Prognostic Index. Patients underwent an R-Double-CHOP regimen, a dose-intensified immunochemotherapy with or without consolidative high-dose chemotherapy followed by autologous stem cell transplantation.

Adult acute lymphoblastic leukemia with a rare b3a3 type BCR/ABL1 fusion transcript.

The Philadelphia chromosome (Ph) is the most frequent chromosomal abnormality detected in adult acute lymphoblastic leukemia (ALL). This chromosome forms the BCR/ABL1 fusion gene; thus, ABL1 exon a2 is generally used as a primer-binding region for the detection of the fusion transcript via reverse transcription polymerase chain reaction (RT-PCR). We observed a rare case of adult Ph-positive (Ph(+)) ALL, in which the BCR/ABL1 fusion transcript was not detected using the ABL1 exon a2 region primer.
