Effects of canagliflozin on brain natriuretic peptide levels in patients with type 2 diabetes on peritoneal dialysis in Japan: protocol for a multicentre, prospective, randomised controlled trial (CARD-PD trial).

Introduction: Patients with type 2 diabetes (T2D) undergoing dialysis exhibit a higher mortality rate compared with those with other conditions, primarily due to vascular complications including coronary artery disease, heart failure and stroke. Sodium-glucose cotransporter 2 (SGLT2) inhibitors, a type of drug for T2D, have reportedly decreased cardiovascular and renal events in patients with heart failure and chronic kidney disease, irrespective of diabetes presence. Nevertheless, the evidence supporting the use of SGLT2 inhibitors in patients undergoing dialysis has been limited.

A multicenter, prospective, phase II trial of second-line aflibercept plus FOLFIRI in patients with metastatic colorectal cancer refractory to an anti-EGFR antibody: HGCSG1801.

Aflibercept (AFL) plus FOLFIRI prolongs overall survival (OS) in patients with metastatic colorectal cancer (mCRC). However, there is limited evidence on the efficacy and safety of AFL plus FOLFIRI previously treated with anti-epidermal growth factor receptor (EGFR) agents. Therefore, we conducted a prospective open-label phase II trial evaluating the efficacy and safety of AFL plus FOLFIRI in Japanese patients with mCRC failing a prior oxaliplatin-based chemotherapy plus an anti-EGFR agent.

Correlation of Gene Polymorphisms or Prior Irinotecan Treatment and Treatment Outcomes of Nanoliposomal-Irinotecan plus 5-Fluorouracil/Leucovorin for Pancreatic Ductal Adenocarcinoma: A Multicenter, Retrospective Cohort Study (HGCSG2101).

The effects of gene polymorphisms or prior irinotecan treatment on treatment outcomes of nanoliposomal-irinotecan plus 5-fluorouracil/leucovorin (nal-IRI+5-FU/LV) in patients with unresectable pancreatic ductal adenocarcinoma (PDAC) are not established. This multicenter, retrospective cohort study compared treatment outcomes in patients with and those with or genotypes. We also analyzed the impact of prior irinotecan treatment on survival outcomes in 54 patients treated with nal-IRI+5-FU/LV.

Feasibility of edoxaban for asymptomatic cancer-associated thrombosis in Japanese patients with gastrointestinal cancer: ExCAVE study.

Background: Although initial therapy with a parenteral anticoagulant is required before edoxaban, this strategy is frequently avoided in actual clinical practice because of its complexity. This study assessed the feasibility of edoxaban without initial heparin usage for asymptomatic cancer-associated thrombosis (CAT) in Japanese patients with gastrointestinal cancer (GIC) at high risk of bleeding.

Methods: In this multicenter prospective feasibility study conducted at 10 Japanese institutions, patients with active GIC who developed accidental asymptomatic CAT during chemotherapy were recruited.

Effects of switching from a dipeptidyl peptidase-4 inhibitor to oral semaglutide on glucose metabolism in patients with type 2 diabetes: protocol for a multicentre, prospective, randomised, open-label, parallel-group comparison study (the SWITCH-SEMA 2 study).

Introduction: Incretin-based therapies exert antihyperglycaemic effects in patients with type 2 diabetes (T2D) in a blood glucose concentration-dependent fashion. The first-in-class oral glucagon-like peptide-1 receptor agonist semaglutide has potent effects on glycaemic and weight control, but little evidence has been published for the superiority of semaglutide for glycaemic control in patients after switching from a dipeptidyl peptidase-4 (DPP-4) inhibitor. Therefore, we aim to verify the efficacy of oral semaglutide in patients with T2D being treated with a DPP-4 inhibitor.

Study protocol of the HGCSG1803: a phase II multicentre, non-randomised, single-arm, prospective trial of combination chemotherapy with oxaliplatin, irinotecan and S-1 (OX-IRIS) as first-line treatment for metastatic or relapsed pancreatic cancer.

Introduction: Combination chemotherapy with oxaliplatin, irinotecan, fluorouracil and leucovorin (FOLFIRINOX) has become one of the standard treatments for metastatic pancreatic cancer. However, the use of FOLFIRINOX requires prolonged infusion. Therefore, we planned to develop a new combination chemotherapy regimen with oxaliplatin, irinotecan and S-1 (OX-IRIS) for advanced pancreatic cancer.

Beneficial effects of switching to denosumab from bisphosphonates or selective estrogen receptor modulators in postmenopausal women with type 2 diabetes and osteopenia/osteoporosis.

Aims/introduction: Patients with type 2 diabetes mellitus have a higher bone fracture risk than patients without diabetes. Although denosumab (Dmab) is a potent bone resorption inhibitor, its efficacy in patients with type 2 diabetes mellitus has not been elucidated. In this study, we investigated the effects of switching to Dmab from bisphosphonates (BP) or a selective estrogen receptor modulator (SERM) in postmenopausal type 2 diabetes mellitus patients.

Impact of single-heterozygous UGT1A1 on the clinical outcomes of irinotecan monotherapy after fluoropyrimidine and platinum-based combination therapy for gastric cancer: a multicenter retrospective study.

Background: It is unclear whether the UGT1A1 status, single heterozygous (SH) or wild type (WT), is associated with the efficacy and toxicity of irinotecan monotherapy in advanced gastric cancer (AGC). We investigated the association between clinical outcomes (efficacy and safety) and UGT1A1 status in patients who received irinotecan monotherapy.

Methods: We evaluated AGC patients who received irinotecan monotherapy between January 2011 and December 2017.

Acute progressing hepatic angiosarcoma: An autopsy case report.

A man in his 50s presented with pitting edema of both lower legs and abdominal distension as his chief complaint. His personal medical history and family history were unremarkable, except that he was a heavy drinker consuming 66 g of alcohol per day and a heavy smoker. Blood tests upon admission showed slight hepatic dysfunction, thrombocytopenia, jaundice, hypoalbuminemia, and decreased coagulability.

Efficacy and Safety of Complete Endoscopic Resection of Colorectal Neoplasia Using a Stepwise Endoscopic Protocol with SOUTEN, a Novel Multifunctional Snare.

Background/aims: A multifunctional snare SOUTEN has a sharp tip at the top of the snare loop that enables incision of the mucosa, dissection of the submucosal layer, and snaring of lesion. This study assessed the efficacy and safety of complete endoscopic resection of colorectal neoplasia using SOUTEN.

Methods: We analyzed the rates of gross en bloc resection and complete resections of 108 consecutive tumors from 69 patients resected by precutting endoscopic mucosal resection (precutting), hybrid endoscopic submucosal dissection (hybrid), or conventional endoscopic submucosal dissection (conventional) using SOUTEN.

Validity of endoscopic features for the diagnosis of Helicobacter pylori infection status based on the Kyoto classification of gastritis.

Objectives: Evaluation of Helicobacter pylori infection status (non-infection, past infection, current infection) has become important. This study aimed to determine the usefulness of the Kyoto classification of gastritis for diagnosing H. pylori infection status by endoscopy.

Corticosteroid dose increase is a risk factor for nonalcoholic fatty liver disease and contralateral osteonecrosis of the femoral head: a case report.

Background: The incidence of bilateral corticosteroid-induced osteonecrosis of the femoral head (ONFH) is high. Although the precise mechanism of corticosteroid-induced ONFH development is unclear, hepatic enzyme abnormalities such as low activity of hepatic cytochrome P450 3A could be one cause. Herein, we report the case of a patient who developed ONFH in the contralateral hip after the dose of corticosteroids for idiopathic thrombocytopenic purpura was increased.

Usefulness of transabdominal ultrasonography for assessing ulcerative colitis: a prospective, multicenter study.

Background: Transabdominal ultrasonography (US) has been reported to be a useful tool for evaluating ulcerative colitis (UC) although with less well-established data than for Crohn's disease. This prospective multicenter study aimed to establish the usefulness of US compared with colonoscopy (CS) for assessing disease extent and activity of UC.

Methods: Altogether, 173 patients with UC were prospectively enrolled, among whom 156 were eligible for this study.

To investigate the safety, effectiveness, and risk-benefit balance of intravenous abatacept (ABA) in non-elderly (<65 years: NEG) and elderly (≥65 years: EG) rheumatoid arthritis patients. This sub-analysis of an all-cases postmarketing surveillance in Japan assessed safety in all enrolled patients and effectiveness in those with Disease Activity Score 28 based on C-reactive protein (DAS28-CRP) measurements at ≥2 time points including baseline. Risk-benefit was evaluated based on infections and DAS28-CRP improvement >1.

Validation of formula-predicted glaucomatous optic disc appearances: the Glaucoma Stereo Analysis Study.

Aims: The Glaucoma Stereo Analysis Study (GSAS) is a multicentre collaborative study of the characteristics of glaucomatous optic disc morphology using a stereo fundus camera. Using the GSAS dataset, we previously established a formula for predicting different appearances of glaucomatous optic discs, although the formula lacked validation in an independent dataset. In this study, the formula was validated in another testing dataset.

Safety and effectiveness of iguratimod in patients with rheumatoid arthritis: Final report of a 52-week, multicenter postmarketing surveillance study.

Objectives: We evaluated the long-term (52 weeks) safety and effectiveness of iguratimod (IGU) in patients with rheumatoid arthritis (RA).

Methods: This multicenter, prospective, observational study included all evaluable RA patients who received IGU since its market launch in 2012. We evaluated adverse events (AEs); adverse drug reactions (ADRs); ADRs of special interest, including liver and renal dysfunctions, interstitial lung disease, gastrointestinal and blood disorders, and infection; and change in Disease Activity Score 28-C-reactive protein (DAS28-CRP) at week 52.

Safety of Cold Polypectomy for Colorectal Polyps in Patients on Antithrombotic Medication.

Background: The cold polypectomy (CP) technique has been increasingly used in recent years. However, there have been few studies about post-polypectomy bleeding (PPB) in patients who underwent CP and who were on antithrombotic drugs. The objective of this study was to determine the safety of CP in patients on antithrombotic medication.

Study protocol of HGCSG1404 SNOW study: a phase I/II trial of combined chemotherapy of S-1, nab-paclitaxel and oxaliplatin administered biweekly to patients with advanced gastric cancer.

Background: In Japan, S-1 plus cisplatin (SP) regimen has become a standard therapy for patients with advanced gastric cancer. Moreover, the S-1 plus oxaliplatin regimen is now a standard treatment. Nab-paclitaxel was developed for chemotherapy of gastric cancer in Japanese clinical practice.

Clinical efficacy, radiographic, and safety results of golimumab monotherapy in Japanese patients with active rheumatoid arthritis despite prior therapy with disease-modifying antirheumatic drugs: Final results of the GO-MONO trial through week 120.

Objective: Evaluate the safety and efficacy of golimumab through week 120 in Japanese patients with active rheumatoid arthritis (RA) previously treated with DMARDs.

Methods: Japanese patients with active RA despite prior DMARDs were randomized to placebo (Group 1, n = 105), golimumab 50 mg (Group 2, n = 101), or golimumab 100 mg (Group 3, n = 102). At week 16, Group 1 patients crossed over to golimumab 50mg; after week 52, a one-time golimumab dose reduction from 100 to 50 mg was permitted.

High titers of both rheumatoid factor and anti-CCP antibodies at baseline in patients with rheumatoid arthritis are associated with increased circulating baseline TNF level, low drug levels, and reduced clinical responses: a post hoc analysis of the RISING study.

Background: Although both rheumatoid factor (RF) and anticyclic citrullinated peptide antibodies (anti-CCP) are useful for diagnosing rheumatoid arthritis (RA), the impact of these autoantibodies on the efficacy of tumor necrosis factor (TNF) inhibitors has been controversial. The aim of this post hoc analysis of a randomized double-blind study (the RISING study) was to investigate the influences of RF and anti-CCP on the clinical response to infliximab in patients with RA.

Methods: Methotrexate-refractory patients with RA received 3 mg/kg of infliximab from weeks 0 to 6 and then 3, 6, or 10 mg/kg every 8 weeks from weeks 14 to 46.
