The primary objective of this study was to examine the association between hypoglycemia problem-solving (HPS) abilities and severe hypoglycemic events in adults with T1D using Poisson regression analysis.

Methods: In this cross-sectional study, 287 adults with T1D (mean age: 50.

Urgent Contrast-Enhanced Computed Tomography before Early Colonoscopy in the Management of Colonic Diverticular Bleeding: A Multicenter Randomized Controlled Trial.

Introduction: Contrast-enhanced computed tomography (CE-CT) has been gaining attention as an initial investigation in the management of colonic diverticular bleeding (CDB), yet the role of CE-CT other than its diagnostic yield has not been adequately clarified. We aimed to determine whether the use of urgent CE-CT improves identification of stigmata of recent hemorrhage (SRH) in subsequently performed early colonoscopy (≤24 h of arrival) or other clinical outcomes of CDB.

Methods: We conducted a randomized, open-label, controlled trial at 23 institutions in Japan.

Alectinib maintenance therapy following cord blood transplantation for relapsed pediatric anaplastic large cell lymphoma with central nervous system involvement.

Pediatric ALK-positive anaplastic large cell lymphoma is a rare subtype of non-Hodgkin lymphoma, and approximately 30% of patients relapse following treatment with conventional chemotherapy. Alectinib monotherapy has demonstrated excellent activity in relapsed and refractory ALCL, but its role as a maintenance therapy after hematopoietic cell transplantation is unclear. We experienced a relapse case of pediatric ALK-positive ALCL with central nervous system involvement treated with alectinib maintenance therapy following cord blood transplantation.

Worldwide CTEPH Registry: Long-Term Outcomes With Pulmonary Endarterectomy, Balloon Pulmonary Angioplasty, and Medical Therapy.

Background: The European Chronic Thromboembolic Pulmonary Hypertension (CTEPH) registry, conducted between 2007 and 2012, reported the major impact of pulmonary endarterectomy (PEA) on the long-term survival of patients with CTEPH. Since then, 2 additional treatments for inoperable CTEPH have become available: balloon pulmonary angioplasty (BPA), and an approved oral drug therapy with the guanylate cyclase stimulator riociguat. The current registry aimed to evaluate the effect of these new therapeutic approaches in a worldwide context.

Chronic thromboembolic pulmonary disease.

Chronic thromboembolic pulmonary hypertension is a complication of pulmonary embolism and a treatable cause of pulmonary hypertension. The pathology is a unique combination of mechanical obstruction due to failure of clot resolution, and a variable degree of microvascular disease, that both contribute to pulmonary vascular resistance. Accordingly, multiple treatments have been developed to target the disease components.

Outcomes of Chronic Thromboembolic Pulmonary Hypertension After Balloon Pulmonary Angioplasty and Pulmonary Endarterectomy.

Background: The contemporary outcome of balloon pulmonary angioplasty (BPA) and pulmonary endarterectomy (PEA) in patients with chronic thromboembolic pulmonary hypertension (CTEPH) are unclear.

Objectives: This study aimed to clarify the characteristics and outcomes of CTEPH patients treated with BPA and PEA in Japan.

Methods: Among 1,270 participants enrolled between 2018 and 2023 in the CTEPH AC (Chronic Thromboembolic Pulmonary Hypertension Anticoagulant) registry, a Japanese nationwide CTEPH registry, 369 treatment-naive patients (BPA strategy: n = 313; PEA strategy: n = 56) and 690 on-treatment patients (BPA strategy: n = 561; PEA strategy: n = 129) were classified according to the presence of prior reperfusion therapy.

Plasma angiotensin-converting enzyme 2 (ACE2) is a marker for renal outcome of diabetic kidney disease (DKD) (U-CARE study 3).

Introduction: ACE cleaves angiotensin I (Ang I) to angiotensin II (Ang II) inducing vasoconstriction via Ang II type 1 (AT1) receptor, while ACE2 cleaves Ang II to Ang (1-7) causing vasodilatation by acting on the Mas receptor. In diabetic kidney disease (DKD), it is still unclear whether plasma or urine ACE2 levels predict renal outcomes or not.

Research Design And Methods: Among 777 participants with diabetes enrolled in the Urinary biomarker for Continuous And Rapid progression of diabetic nEphropathy study, the 296 patients followed up for 9 years were investigated.

Closure of the Entire Fistula With Highly Effective Chemocauterization Using the Distal Hood Endoscope: A Novel Procedure for the Treatment of Pyriform Sinus Fistula.

Background: Pyriform sinus fistula (PSF) causes a recurrent abscess in the neck. Endoscopic chemocauterization with trichloroacetic acid (TCA) for PSF is a simple, reproducible, and reliable procedure for treating PSF; however, there is concern about complications caused by TCA overflowing into the larynx. To prevent these complications, we devised a highly effective chemocauterization using a distal hooded endoscope (HuDHE).

Effect of Antacids on the Survival of Patients With Metastatic Urothelial Carcinoma Treated With Pembrolizumab.

Introduction: Concomitant medications can affect the efficacy of immune checkpoint inhibitors. The association between histamine-2 receptor antagonists (H2RAs), major antacids similar to proton pump inhibitors (PPIs), and the efficacy of pembrolizumab for metastatic urothelial carcinoma (mUC) treatment has been poorly evaluated. We evaluated the impact of PPIs and H2RAs on oncological outcomes in mUC patients treated with pembrolizumab.

Safety and efficacy of airway stent placement following bronchial artery embolization: A retrospective study at a single institute.

Background: Airway stenting is an established procedure for treating oncological emergencies in patients with airway disorders. In patients with airway hemorrhage, respiratory conditions may worsen during stenting. Bronchial artery embolization (BAE) is useful to prevent bleeding from the bronchus.
