Accuracy of the Hounsfield Unit Values Measured by Implant Planning Software.

: The measurement of Hounsfield units (HU) during implant treatment planning is important. Currently, various manufacturers' implant planning software programs offer HU capabilities; however, their accuracy remains unverified. In this study, we aimed to validate the accuracy of HU values measured by implant planning software programs.

Hybrid Endovascular and Direct Surgical Approach for Treatment of Penetrating Common Carotid Artery Injury: A Case Report.

Although rare, penetrating cervical vascular injury poses significant challenges with a poor patient prognosis, often attributed to severe hemorrhage and accompanying injuries. We encountered a case of hemorrhagic shock resulting from a penetrating injury to the common carotid artery (CCA), which was successfully managed using a combination of endovascular therapy and direct surgical intervention. A 23-year-old man presented with a self-inflicted stab wound on the left side of his neck from a kitchen knife.

Machine Learning Prediction for Postdischarge Falls in Older Adults: A Multicenter Prospective Study.

Objectives: The study aimed to develop a machine learning (ML) model to predict early postdischarge falls in older adults using data that are easy to collect in acute care hospitals. This may reduce the burden imposed by complex measures on patients and health care staff.

Design: This prospective multicenter study included patients admitted to and discharged from geriatric wards at 3 university hospitals and 1 national medical center in Japan between October 2019 and July 2023.

Association between the HAL score and the development of progressive pulmonary fibrosis in idiopathic interstitial pneumonia: A prospective observational study.

Background: Progressive pulmonary fibrosis (PPF) is a critical concern in interstitial lung disease (ILD) management. The HAL score, which incorporates honeycombing (H), age >75 years (A), and serum lactate dehydrogenase >222 U/L (L), can predict acute exacerbations in patients with idiopathic interstitial pneumonia (IIP). This study aims to evaluate the predictive utility of the HAL score for PPF development.

Novel photochromic system using methylene blue reduction with l-ascorbic acid.

A novel photochromic system was discovered, in which leucomethylene blue, reduced by l-ascorbic acid, was irradiated with 405 nm visible light, resulting in the solution undergoing a colorless-to-blue transition. The process was then repeated, with the solution returning to its colorless state when left undisturbed. This photochromic reaction is sensitive enough to be driven by a blue-violet LED lamp and enables figures to be drawn in solution with a laser pointer.
