Article Abstract
The filter extraction method is a new, simple method for evaluating anticancer drug contamination in air. The method involves installing a filter in the exhaust port of an exhaust duct on a facility's air conditioner, then collecting and measuring fine particles of the antineoplastic agents adsorbed onto the filter. In this study, we analyzed the utility of maintaining continuous filter extraction for measuring cyclophosphamide and 5-fluorouracil contamination. The filters were installed in 3 areas of an outpatient chemotherapy room and then left in place for approximately 5 months. Results revealed the presence of cyclophosphamide and 5-fluorouracil in all 3 areas. However, the amounts and ratios of detected drugs differed among survey sites; this may have been caused by factors such as drug preparation, administration, and excretion. We conclude that the filter extraction method can be used continuously for monitoring anticancer drug contamination in air; thus, it can be utilized to monitor healthcare workers' occupational exposure to inhaled anticancer drugs. Indeed, the filter extraction method may be useful as a novel environmental monitoring technique.

This study investigates the relationship between dietary antioxidants and heart failure (HF) risk using nationally representative National Health and Nutrition Examination Survey data (2005-2018). It aims to identify key dietary antioxidants and develop a machine-learning-based predictive model for HF. Among 9279 participants (434 HF cases), 44 dietary antioxidant variables were extracted from two 24-h dietary recalls.

Introduction: Accurate and non-invasive blood glucose estimation is essential for effective health monitoring. Traditional methods are invasive and inconvenient, often leading to poor patient compliance. This study introduces a novel approach that leverages systolic-diastolic framing Mel-frequency cepstral coefficients (SDFMFCC) to enhance the accuracy and reliability of blood glucose estimation using photoplethysmography (PPG) signals.

The accurate detection of trace perfluoroalkyl acids (PFAAs) in drinking water remains challenging due to nonspecific adsorption losses during pretreatment. This study systematically evaluated the adsorption behaviors of 11 PFAAs across five filtration membranes and four solid-phase extraction (SPE) sorbents to establish an optimized analytical protocol. Results demonstrated that glass fiber (GL) filters minimized PFAAs retention (94.

Accurate prediction of drug-target interactions (DTIs) is crucial for improving the efficiency and success rate of drug development. Despite recent advancements, existing methods often fail to leverage interaction features at multiple granular levels, resulting in suboptimal data utilization and limited predictive performance. To address these challenges, we propose CF-DTI, a coarse-to-fine drug-target interaction model that integrates both coarse-grained and fine-grained features to enhance predictive accuracy.

This paper presents ClinicSum, a novel framework designed to automatically generate clinical summaries from patient-doctor conversations. It utilizes a two-module architecture: a retrieval-based filtering module that extracts Subjective, Objective, Assessment, and Plan (SOAP) information from conversation transcripts, and an inference module powered by fine-tuned Pre-trained Language Models (PLMs), which leverage the extracted SOAP data to generate abstracted clinical summaries. To fine-tune the PLM, we created a training dataset of consisting 1,473 conversations-summaries pair by consolidating two publicly available datasets, FigShare and MTS-Dialog, with ground truth summaries validated by Subject Matter Experts (SMEs).
