Background: Falls on stairs are a major cause of severe injuries among older adults, with stair descent posing significantly greater risks than ascent. Variations in stair descent phenotypes may reflect differences in physical function and biomechanical stability, and their identification may prevent falls.

Aims: This study aims to classify stair descent phenotypes in older adults and investigate the biomechanical and physical functional differences between these phenotypes using hierarchical cluster analysis.

Generative artificial intelligence enables the generation of bone scintigraphy images and improves generalization of deep learning models in data-constrained environments.

Eur J Nucl Med Mol Imaging

January 2025

Department of Biomedical Imaging and Image-guided Therapy, Division of Nuclear Medicine, Medical University of Vienna, Spitalgasse 23, Vienna, 1090, Austria.

Purpose: Advancements of deep learning in medical imaging are often constrained by the limited availability of large, annotated datasets, resulting in underperforming models when deployed under real-world conditions. This study investigated a generative artificial intelligence (AI) approach to create synthetic medical images taking the example of bone scintigraphy scans, to increase the data diversity of small-scale datasets for more effective model training and improved generalization.

Methods: We trained a generative model on Tc-bone scintigraphy scans from 9,170 patients in one center to generate high-quality and fully anonymized annotated scans of patients representing two distinct disease patterns: abnormal uptake indicative of (i) bone metastases and (ii) cardiac uptake indicative of cardiac amyloidosis.

Artificial intelligence-enhanced magnetic resonance imaging-based pre-operative staging in patients with endometrial cancer.

Int J Gynecol Cancer

January 2025

Institute of Image-Guided Surgery, IHU Strasbourg, France; University of Strasbourg, ICube, Laboratory of Engineering, Computer Science and Imaging, Department of Robotics, Imaging, Teledetection and Healthcare Technologies, CNRS, UMR, Strasbourg, France.

Objective: Evaluation of prognostic factors is crucial in patients with endometrial cancer for optimal treatment planning and prognosis assessment. This study proposes a deep learning pipeline for tumor and uterus segmentation from magnetic resonance imaging (MRI) images to predict deep myometrial invasion and cervical stroma invasion and thus assist clinicians in pre-operative workups.

Methods: Two experts consensually reviewed the MRIs and assessed myometrial invasion and cervical stromal invasion as per the International Federation of Gynecology and Obstetrics staging classification, to compare the diagnostic performance of the model with the radiologic consensus.

Mitochondria-localized dinuclear iridium(III) complexes for two-photon photodynamic therapy.

Dalton Trans

January 2025

MOE Key Laboratory of Bioinorganic and Synthetic Chemistry, Guangdong Basic Research Center of Excellence for Functional Molecular Engineering, School of Chemistry, Sun Yat-sen University, Guangzhou, 510275, P. R. China.

Photodynamic therapy (PDT), as a non-invasive cancer treatment, offers significant advantages including high temporal-spatial selectivity, minimal surgical intervention, and low toxicity, thereby garnering considerable research interest from across the world. In this study, we have developed a series of dinuclear cyclometalated Ir(III) complexes as potential two-photon photodynamic anticancer agents. These Ir(III) complexes demonstrate significant two-photon absorption (2PA) cross-sections ( = 66-166 GM) and specifically target mitochondria.

Background: The information and decision support needs required to embed a patient-centred strategy are challenging, as several haemodialysis vascular access strategies are possible with significant differences in short- and long-term outcomes of potential treatment options. We aimed to explore and describe stakeholder perspectives on information needs when making decisions about vascular access (VA) for haemodialysis.

Methods: We performed thematic analysis of seven (six online, one in person) focus group discussions including transcripts, post-it phrases and text responses with 14 patients and 12 vascular access professionals (four nephrologists, three surgeons and five nurses - Vascular access nurse specialists/Education and dialysis nurses) who participated in at total of six online and one in person focus group.

Article Synopsis
  • Hypomanic personality traits (HPT) are linked to higher risk for psychiatric disorders like bipolar disorder and are associated with aggressive behaviors, yet the underlying neuropsychological mechanisms are not fully understood.
  • The study used psychometric network analysis to identify key factors (Behavioral Inhibition System and mood volatility) that connect HPT to aggression, finding that mood volatility positively correlates with aggression, with BIS acting as a mediator.
  • Further imaging studies revealed distinct functions of the dorsal and ventral sensorimotor cortices in processing rewards, and resting-state imaging confirmed these regions' connections to different brain networks, highlighting the importance of these circuits in mediating the relationship between mood volatility, aggression, and BIS.
