Effects of applying high-pass filtering in pelvimetry with Martius images.

Aim: The aim of this study is to investigate whether the results of pelvimetry using original radiographic Martius images and the same images with high-pass filtering applied ("edge images") would be consistent.

Methods: A total of 30 primagravidas were included in this study. Three obstetricians independently measured the anteroposterior and transverse diameters of the pelvic inlet in the original and the edge images, recording the x- and y-coordinates of the four endpoints.

Pre-first-line chemotherapy risk stratification for overall survival in advanced urothelial carcinoma in sequential therapy era.

Purpose: To explore pre-treatment risk factors for overall survival (OS) in advanced urothelial carcinoma (UC) patients treated with first-line (1L) chemotherapy in sequential therapy (ST) era. Additionally, to evaluate the proportion of patients who were not able to undergo subsequent immune checkpoint inhibitor (ICI) therapy according to the subgroups stratified by the risk factors.

Methods: A multicenter retrospective study was conducted.

A Deep Learning-Based Model for Classifying Osteoporotic Lumbar Vertebral Fractures on Radiographs: A Retrospective Model Development and Validation Study.

Early diagnosis and initiation of treatment for fresh osteoporotic lumbar vertebral fractures (OLVF) are crucial. Magnetic resonance imaging (MRI) is generally performed to differentiate between fresh and old OLVF. However, MRIs can be intolerable for patients with severe back pain.

Blood flow characteristics of the bilateral internal thoracic artery: implications of optimal graft configuration for coronary artery bypass grafting to maximize blood supply.

Purpose: There is controversy regarding which internal thoracic artery (ITA) should be anastomosed to the left anterior descending artery (LAD). Here, we propose an optimal graft design based on measurement of blood flow in the ITA.

Methods: Sixty-one patients (53 men, median age 68 [62-75] years) undergoing first elective coronary artery bypass grafting were enrolled.

[An Anastomotic Aneurysm Thirty Years After Open Surgery of the Descending Thoracic Aorta:Report of a Case].

An 86-year-old man was hospitalized urgently to our department because of his worsening hemoptysis. He had undergone open thoracic aortic grafting for the Stanford type B chronic aortic dissecting aneurysm 30 years earlier. Contrast enhanced computed tomography (CT) revealed the distal anastomotic aneurysm, leakage of the contrast medium around the distal anastomotic site.

Real-World Data Analysis of Pembrolizumab Monotherapy for NSCLC Using Japanese Postmarketing All-Case Surveillance Data.

Introduction: Pembrolizumab is a programmed death-ligand 1 inhibitor that was initially indicated for monotherapy in patients with advanced lung cancer. The Japanese Lung Cancer Society conducted an observational study on pembrolizumab using confirmative data obtained through postmarketing all-case surveillance (PMACS), which was performed by a pharmaceutical company under the Japanese law in 2017.

Methods: This multicenter observational study was conducted by the Japanese Lung Cancer Society using PMACS data with the newly created central registration system regarding patients with NSCLC who received pembrolizumab monotherapy between February 1, 2017 and June 30, 2017; a new database was created by adding the clinical information regarding prognosis for 3 years after therapy to the existing data collected by PMACS.

Development of a hyperosmolar-hyperglycemic state and possible fulminant type 1 diabetes mellitus during the treatment of a case of adenocarcinoma of the lung and interstitial pneumonia.

An 85-year-old man was being treated with anti-cancer drugs for adenocarcinoma of the lung and was on a tapering dose of prednisolone for interstitial pneumonia. He attended our hospital complaining of fatigue, thirst, and polyuria in September 2020. His postprandial plasma glucose concentration was 976 mg/dL, his glycated hemoglobin was 8.
