Article Abstract
Research trend analysis is a primary step in defining research structures and predicting research directions from scientific papers. Recently, due to millions of annual scientific publications, researchers demand analytical methods to interpret the research field topologically and temporally. In this study, we propose a keyword-based research trend analysis method that automatically and systematically analyzes the research field by extracting keywords and constructing a keyword network. We verified our method on the resistive random-access memory (ReRAM) research field, which is in the limelight as an alternative device for non-volatile memory and artificial synapses. Our method performs three sequential processes: article collection, keyword extraction, and research structuring. We identified three keyword communities of ReRAM based on the processing-structure-property-performance (PSPP) relationship and found an upward trend in Neuromorphic applications. As a result, our method successfully structures the ReRAM research field and is expected to provide detailed insights into various research fields.

Pre-employment urine drug screening: examining trends in THC-COOH positivity rates post-legalization of recreational cannabis in California - a retrospective review.
J Occup Med Toxicol
September 2025
Occupational Medicine, Antioch Medical Center, Kaiser Permanente, 4501 Sand Creek Road, Antioch, CA, 94531, USA.
Background: This study examines trends in delta-9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH) positivity rates in pre-employment urine drug screenings at a single university-based hospital occupational medicine clinic from 2017 to 2022, following California's recreational cannabis legalization in 2016, with sales beginning officially on January 1, 2018.
Methods: Retrospective analysis of 21,546 de-identified urine drug screenings from 2017 to 2022 was conducted. Initial screening used instant urine drug immunoassays (50 ng/mL cutoff for THC-COOH), followed by confirmatory gas chromatography-mass spectrometry (15 ng/mL cutoff).
Adherence trends to the Mediterranean Diet in Spanish youth: A systematic review and meta-analysis.

July 2025
Universidad de Castilla-La Mancha, Health and Social Research Center, Cuenca, 16071, Spain; Universidad Autónoma de Chile, Facultad de Ciencias de la Salud, Talca, 1101, Chile.
Aims: Young people are consuming less healthy diets such as Mediterranean diet (MedDiet), which is associated with an increased risk of chronic diseases, including obesity. This systematic review aimed to synthesize the literature concerning the prevalence and trends of adherence to the (MedDiet) in a young Spanish population (aged 2-24 years) from 2004 to 2023.
Data Synthesis: The present review included observational studies and final assessments of longitudinal studies to assess the prevalence or trend in adherence to the MedDiet using the Mediterranean Diet Quality Index for Children and Adolescents (KIDMED) in three categories (low (≤3), medium (4-7), and high (≥8)).
Orbital Exenteration Trends at a Single Institution From 2011 to 2024.
Ophthalmic Plast Reconstr Surg
September 2025
Department of Ophthalmology, Bascom Palmer Eye Institute.
Purpose: The primary objective was to investigate the trends in orbital exenteration rates at a large tertiary care center, particularly in the context of recent advancements in immunotherapy, targeted agents, and globe-sparing surgical techniques, which have significantly impacted patient management.
Methods: We conducted a retrospective cohort study at the University of Miami. Patients who underwent orbital exenterations from 2011 to 2024 were identified by obtaining surgical coding data via institutional data brokers and validated through a rigorous surgical chart review.
Investigating Information Visualization to Combat Information Overload in Electronic Health Records: Protocol for a Randomized Controlled Trial.

Background: Electronic health records (EHRs) have been linked to information overload, which can lead to cognitive fatigue, a precursor to burnout. This can cause health care providers to miss critical information and make clinical errors, leading to delays in care delivery. This challenge is particularly pronounced in medical intensive care units (ICUs), where patients are critically ill and their EHRs contain extensive and complex data.

A number of techniques have been developed to measure the three-dimensional trajectories of protists, which require special experimental set-ups, such as a pair of orthogonal cameras. On the other hand, machine learning techniques have been used to estimate the vertical position of spherical particles from the defocus pattern, but they require the acquisition of a labelled dataset with finely spaced vertical positions. Here, we describe a simple way to make a dataset of images labelled with vertical position from a single 5 min movie, based on a tilted slide set-up.
