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.

Clinical analysis of progressive destroyed lung after lung cancer surgery.

Background: "Progressive destroyed lung (PDL)" refers to a state in which the normal structure and function of the lung are permanently disrupted owing to repeated inflammation. After lung cancer surgery, the remaining lung tissue can experience progressive destruction; however, the exact cause remains unclear. In this study, we retrospectively analyzed cases in which the remaining lung deteriorated after lung cancer surgery and investigated the associated risk factors.

Mechanisms of resistance and correlation between pre-treatment co-alterations and p-prognosis to osimertinib in chemo-naïve advanced non-small cell lung cancer.

Background: Several patients treated with osimertinib experience progressive disease. The aim was to clarify the mechanisms underlying resistance to osimertinib.

Methods: ELUCIDATOR: A multi-centre, prospective, observational study involved chemotherapy-naive patients with advanced non-small cell lung cancer receiving osimertinib.

ZFP36 family expression is suppressed by Th2 cells in asthma, leading to enhanced synthesis of inflammatory cytokines and cell surface molecules.

Asthma is a chronic inflammatory airway disease, in which inflammatory cytokines play a pivotal role. The zinc finger binding protein 36 (ZFP36) family includes ZFP36, ZFP36L1, and ZFP36L2 and is among the RNA-binding proteins (RBPs) reported to cause inflammation. The present study aimed to clarify the roles of the ZFP36 family in asthma, particularly highlighting the relationship between the ZFP36 family and Th2 cells, which are key players in type 2 inflammation in asthma.

Pulmonary Hypertension With Interstitial Pneumonia: Initial Treatment Effectiveness and Severity in a Japan Registry.

Background: Recent guidelines discourage the use of pulmonary arterial hypertension (PAH)-targeted therapies in patients with pulmonary hypertension (PH) associated with respiratory diseases. Therefore, stratifications of the effectiveness of PAH-targeted therapies are important for this group.

Objectives: The authors aimed to identify phenotypes that might benefit from initial PAH-targeted therapies in patients with PH associated with interstitial pneumonia and combined pulmonary fibrosis and emphysema.

Subjective and objective image quality of low-dose CT images processed using a self-supervised denoising algorithm.

This study aimed to assess the subjective and objective image quality of low-dose computed tomography (CT) images processed using a self-supervised denoising algorithm with deep learning. We trained the self-supervised denoising model using low-dose CT images of 40 patients and applied this model to CT images of another 30 patients. Image quality, in terms of noise and edge sharpness, was rated on a 5-point scale by two radiologists.

Radiological and histopathological features and treatment response by subtypes of interstitial pneumonia with autoimmune features: A prospective, multicentre cohort study.

Background: Patients with idiopathic interstitial pneumonia (IIP) have a favourable prognosis when they have interstitial pneumonia with autoimmune features (IPAF). However, precise IPAF-related findings from high-resolution computed tomography (HRCT) and lung histopathological specimens and the treatment response have not been fully determined. Therefore, this study was conducted to evaluate the relationship between findings on HRCT or lung histopathological specimens and the progression of interstitial pneumonia in patients with IPAF.

PLA2R-positive membranous nephropathy in IgG4-related disease.

Background: IgG4-related disease (IgG4-RD) is a fibroinflammatory disease that affects multiple organs, including the pancreas, lacrimal glands, salivary glands, periaortic/retroperitoneum, and kidney. Interstitial nephritis is a typical renal disorder associated with IgG4-RD, but membranous nephropathy is also seen in some cases.

Case Presentation: Herein we report on the case of a 77-year-old male patient with nephrotic syndrome and IgG4-related lung disease.

Cancer-Chemotherapy-Related Regimen Checks Performed by Pharmacists of General Hospitals Other than Cancer Treatment Collaborative Base Hospitals: A Multicenter, Prospective Survey.

Although prescription review is an important role for pharmacists in anticancer drug therapy, there are no guidelines in Japan that specify what pharmacists should check for in chemotherapy regimens. This prospective multicenter survey aimed to investigate the implementation of chemotherapy regimen checks by pharmacists in general hospitals by focusing on 19 recommended confirmation items designed to enhance chemotherapy safety. This study involved 14 hospitals within the National Hospital Organization in different regions of Japan.

High attenuation mucus in bronchi with allergic bronchopulmonary mycosis.

Background: High-attenuation mucus (HAM) is a specific manifestation of allergic bronchopulmonary mycosis (ABPM) on chest computed tomography (CT).

Objectives: To compare the diagnostic accuracy of the two definitions of HAM and to clarify the clinical and radiographic characteristics of HAM-positive and HAM-negative ABPM.

Methods: CT images at the diagnosis of ABPM using Asano's criteria were retrospectively analysed.

Clinical characteristics of allergic bronchopulmonary mycosis caused by Schizophyllum commune.

Background: Allergic bronchopulmonary mycosis (ABPM) is an allergic disease caused by type I and type III hypersensitivity to environmental fungi. Schizophyllum commune, a basidiomycete fungus, is one of the most common fungi that causes non-Aspergillus ABPM.

Objective: Herein, we attempted to clarify the clinical characteristics of ABPM caused by S.
