Probiotic-derived glucose oxidase exerts therapeutic efficacy against pediatric B-cell acute lymphoblastic leukemia.

Recent advances in therapy have significantly improved long-term survival in pediatric B-cell acute lymphoblastic leukemia (B-ALL). However, relapse still occurs in 15-20 % of cases, and post-relapse survival rates remain suboptimal at 30-60 %. Therefore, novel therapeutic strategies effective against both primary and relapsed B-ALL are needed.

Granulocyte and Monocyte Adsorptive Apheresis Maintenance Therapy Restored the Loss of Response to Anti-TNF-Alpha Agents in the Patients With UC: A Case Report.

Ulcerative colitis (UC) is a chronic inflammatory condition requiring lifelong management, with anti-tumor necrosis factor α (anti-TNF-α) agents often used for refractory cases. However, secondary loss of response (LOR) to these agents, due to anti-drug antibodies, poses a significant therapeutic challenge. This report describes a case where granulocyte and monocyte adsorptive apheresis (GMA) maintenance therapy successfully restored the efficacy of an anti-TNF-α agent in a 26-year-old male with active UC experiencing LOR to infliximab.

Curative endoscopic submucosal dissection for esophageal squamous cell carcinoma after chemoradiotherapy for pharyngeal cancer: A case report.

Background: Esophageal squamous cell carcinoma (ESCC) is often managed with surgery, which is the first-line treatment option for stage I-III lesions. However, definitive chemoradiotherapy (dCRT) is associated with a recurrence rate of 30% in stage I ESCC and higher rates in advanced-staged lesions. However, several patients prefer dCRT because their general condition is poor.

The butyrate derived from probiotic Clostridium butyricum exhibits an inhibitory effect on multiple myeloma through cell death induction.

Multiple myeloma (MM) is a hematological malignancy characterized by a poor prognosis. While certain probiotics have been shown to produce antitumor molecules that inhibit solid tumor progression, it remains unclear whether probiotic-derived compounds can exert similar effects on hematological tumors, such as MM. In this study, we screened the cell-free culture supernatants (CFCS) of 24 probiotic strains for antitumor effects against multiple myeloma (MM) cells and identified that the CFCS from Clostridium butyricum (C.

Comparison of traction vs. snare as rescue methods for challenging colorectal endoscopic submucosal dissection: Propensity score-matched study.

Background And Study Aims: To address the challenges of difficult colorectal endoscopic submucosal dissection (ESD), conversion to snare resection (rescue-snare ESD: rSnare), a variant of hybrid ESD, is commonly proposed. However, rSnare is associated with a lower en bloc resection rate compared with conventional ESD. Traction-assisted ESD has emerged as a technique to facilitate dissection, but its effectiveness as a rescue method remains unclear.

Unresectable Ulcerative Colitis Associated Colon Cancer in a Young Japanese Patient.

We herein present the case of a 30-year-old Japanese male patient with ulcerative colitis (UC) who was admitted to our hospital because of significant ascites. Upon evaluation, the patient was diagnosed with unresectable UC-associated colon cancer (UCAC), localized in the transverse colon. Using gene profiling of the tumor tissue, anti-epidermal growth factor receptor (EGFR) antibody combination chemotherapy was selected.

Oral Breathing Facilitates Endoscopic Operability Compared With Nasal Breathing in Peroral Endoscopy: A Randomized Controlled Trial.

Introduction: Unsedated peroral endoscopy, including ultrathin endoscopy (UE) and conventional endoscopy (CE), is feasible in clinical practice but requires improved endoscopic operability and patient tolerance. Currently, the impact of the breathing method on these factors remains unclear. We conducted the first randomized controlled trial comparing oral breathing (OB) and nasal breathing (NB) during both UE and CE to assess their influence.

The white ring sign is useful for differentiating between fundic gland polyps and gastric adenocarcinoma of the fundic gland type.

Gastric adenocarcinoma of the fundic gland type (GA-FG) is characterized by an elevated lesion with vessel dilation exhibiting branching architecture (DVBA). However, this feature is also found in fundic gland polyps (FGPs), posing a challenge in their differentiation. In this study, we aimed to investigate the clinicopathological features of gastric elevated lesions with DVBA and assess the efficacy of the white ring sign (WRS) as a novel marker for distinguishing between FGPs and GA-FGs.

Risk Factors for Post-Colorectal Endoscopic Submucosal Dissection Bleeding and Efficacy of Carbazochrome Sodium Sulfonate: A Multicenter Retrospective Cohort Study.

Introduction: Carbazochrome sodium sulfonate (CSS) is a hemostatic agent that reduces capillary permeability and enhances capillary resistance. However, its specific effects on colorectal endoscopic submucosal dissection (ESD) outcomes remain uncertain. This study aimed to assess the risk factors for post-ESD bleeding and the effect of CSS on colorectal ESD outcomes.

Comparison of diagnostic accuracy between linked color imaging and autofluorescence imaging in patients with ulcerative colitis: A prospective observational study.

Background And Aim: Image enhancement endoscopy techniques, such as linked color imaging (LCI) and autofluorescence imaging (AFI), have shown promise in diagnosing mucosal inflammation in ulcerative colitis (UC). However, no studies have directly compared the diagnostic efficacy of LCI and AFI. This prospective observational study aimed to compare their diagnostic accuracy for histological healing in UC.

Probiotic-derived ferrichrome induces DDIT3-mediated antitumor effects in esophageal cancer cells.

Esophageal cancer, which is common among the elderly, has the poorest prognosis among gastrointestinal cancers. Previously, we demonstrated that ferrichrome, produced by the probiotic , exhibited anti-tumor effects in various gastrointestinal cancers, including colorectal and gastric cancers, with minimal effects on non-cancerous intestinal cells. However, it remains unclear whether ferrichrome exerts anti-tumor effects in esophageal cancer.

Severe immune checkpoint inhibitor-associated gastritis: A case series and literature review.

Recent advances in cancer treatment have involved the clinical application of immune checkpoint inhibitors (ICIs) for various type of cancers. The adverse events associated with ICIs are generally referred to as immune-related adverse events (irAEs). Gastrointestinal irAEs are a major disorder, but gastritis is not frequently observed.

Nasal breathing is superior to oral breathing when performing and undergoing transnasal endoscopy: a randomized trial.

BACKGROUND : Transnasal endoscopy presents a technical difficulty when inserting the flexible endoscope. It is unclear whether a particular breathing method is useful for transnasal endoscopy. Therefore, we conducted a prospective randomized controlled trial to compare endoscopic operability and patient tolerance between patients assigned to nasal breathing or oral breathing groups.

A case report of drug-induced liver injury due to the infliximab biosimilar CT-P13 on switching from original infliximab in a patient with Crohn's disease.

Unlabelled: Inflammatory bowel diseases (IBDs) are chronic immune disorders of unclear etiology. Tumor necrosis factor (TNF) inhibitors are effective for IBD treatment and are cost-effective because they reduce hospital admissions and are associated with fewer surgery requirements and a better quality of life in IBD patients. A large number of clinical trials of infliximab biosimilar (CT-P13) have suggested that the administration of biosimilars provides high efficacy and safety similar to that of the originators, with a lower cost, so switching from the original to a biosimilar is considered an acceptable treatment.
