Objective: The study aims to present an observational study of clinical trials on Oral Potentially Malignant Disorders (OPMDs) and corresponding publications.
Study Design And Setting: We searched the OPMDs-related clinical studies registered in the ClinicalTrials.gov database before March 1, 2024. Subsequently, we investigated the publication status of primary completed studies using PubMed and Google Scholar.
Results: A total of 185 studies were identified for analysis, including 141 interventional studies and 44 observational studies. The most commonly studied disease type was oral lichen planus (OLP), accounting for 113 studies (61.1 %). Interventional studies on OPMDs were predominantly early-phased, blind, randomized, parallel and single-center. The primary purpose of these studies was treatment (106, 75.2 %). Among the treatments, herbal medicine (21, 19.8 %), photodynamic therapy (17, 16.0 %), and glucocorticoids (14, 13.2 %) were of greatest interest. In addition, 58 (63.0 %) of the primarily completed interventional studies were published, with a median time to publication of 33.6 months. Published interventional studies including OLP patients and factorial designs had shorter time to publication. However, these studies were less frequently published in high-impact journals and most primary results were positive.
Conclusions: Clinical trials on OPMDs predominantly focused on OLP and herbal medicine. The quality of studies is unsatisfactory and publication rate is suboptimal. Improvements are needed in ClinicalTrials.gov registration standards, high-quality study design and more stringent publishing requirements.

Aims: Unresectable cutaneous squamous cell cancer of the head and neck (HNcSCC) poses treatment challenges in elderly and comorbid patients. Radiation therapy (RT) is often employed for locoregional control. This study aimed to determine progression-free survival (PFS) and overall survival (OS) outcomes achieved with upfront RT in unresectable HNcSCC.

Background: This study aimed to examine how physician performance metrics are affected by the speed of other attendings (co-attendings) concurrently staffing the ED.
Methods: A retrospective study was conducted using patient data from two EDs between January-2018 and February-2020. Machine learning was used to predict patient length of stay (LOS) conditional on being assigned a physician of average speed, using patient- and departmental-level variables.
National early warning score 2 plus non-invasive capnography and perfusion index to estimate poor outcomes in emergency departments.

Background: The study of the inclusion of new variables in already existing early warning scores is a growing field. The aim of this work was to determine how capnometry measurements, in the form of end-tidal CO2 (ETCO2) and the perfusion index (PI), could improve the National Early Warning Score (NEWS2).
Methods: A secondary, prospective, multicenter, cohort study was undertaken in adult patients with unselected acute diseases who needed continuous monitoring in the emergency department (ED), involving two tertiary hospitals in Spain from October 1, 2022, to June 30, 2023.
Systematic application of saliency maps to explain the decisions of convolutional neural networks for glaucoma diagnosis based on disc and cup geometry.

This paper systematically evaluates saliency methods as explainability tools for convolutional neural networks trained to diagnose glaucoma using simplified eye fundus images that contain only disc and cup outlines. These simplified images, a methodological novelty, were used to relate features highlighted in the saliency maps to the geometrical clues that experts consider in glaucoma diagnosis. Despite their simplicity, these images retained sufficient information for accurate classification, with balanced accuracies ranging from 0.

Mild cognitive impairment (MCI) is a significant predictor of the early progression of Alzheimer's disease, and it can be used as an important indicator of disease progression. However, many existing methods focus mainly on the image itself when processing brain imaging data, ignoring other non-imaging data (e.g.
