Light buckets and laser beams: mechanisms and applications of photobiomodulation (PBM) therapy.
Geroscience
January 2025
National Institute On Aging, Bethesda, MD, USA.
Photobiomodulation (PBM) therapy, a non-thermal light therapy using nonionizing light sources, has shown therapeutic potential across diverse biological processes, including aging and age-associated diseases. In 2023, scientists from the National Institute on Aging (NIA) Intramural and Extramural programs convened a workshop on the topic of PBM to discuss various proposed mechanisms of PBM action, including the stimulation of mitochondrial cytochrome C oxidase, modulation of cell membrane transporters and receptors, and the activation of transforming growth factor-β1. They also reviewed potential therapeutic applications of PBM across a range of conditions, including cardiovascular disease, retinal disease, Parkinson's disease, and cognitive impairment.

Background: Currently, there is an increase in procedures across various clinical specialties involving the use of ionising radiation.
Objective: The primary objective of this systematic review is to analyse and compare the existing literature regarding the effectiveness of leaded glasses for healthcare professionals.
Methods: Comprehensive literature searches were conducted for relevant studies published between 2018 and 2023 using the Scopus, PubMed, and Web of Science databases according to preferred reporting items for systematic reviews and meta-analyses (PRISMA) methodology.
Compliance with radiation protection among radiographers in Eswatini public health facilities.
Health SA
December 2024
Department of Radiography, Faculty of Health Science, Durban University of Technology, Durban, South Africa.
Background: The consequence of non-compliance with patient radiation safety standards increases unnecessary radiation exposure with high chances of harmful biological effects. Radiographers are trained to prevent these harmful effects by enforcing radiation protection, which is achieved through proper techniques, equipment, shielding materials and beam collimation.
Aim: The study aimed to explore compliance with radiation protection by radiographers in Eswatini public health facilities (PHFs).
Metabolomics identifies plasma biomarkers of localized radiation injury.

Institut de Radioprotection et de Sureté Nucléaire (IRSN), PSE-SANTE/SERAMED/LRAcc, 31 av de la Division Leclerc, Fontenay-aux-Roses, 92260, France.
A radiological accident may result in the development of a local skin radiation injury (LRI) which may evolve, depending on the dose, from dry desquamation to deep ulceration and necrosis through unpredictable inflammatory waves. Therefore, early diagnosis of victims of LRI is crucial for improving medical care efficiency. This preclinical study aims to identify circulating metabolites as biomarkers associated with LRI using a C57BL/6J mouse model of hind limb irradiation.

Thoracic Surgery, BASS Medical Group, Walnut Creek, CA.
Background: This study aimed to quantify radiation doses during navigational bronchoscopy procedures, comparing them with reported cohorts and evaluating the LungVision (Body Vision Medical Inc.) system's efficacy in dose reduction.
Methods: This retrospective observational study included 52 consecutive navigational bronchoscopy cases, categorized into 4 imaging groups based on the C-arm: Cios Spin (Siemens Healthineers), or OEC 9900 (GE HealthCare); and the 3D tomographic imaging algorithm: Cios Spin's onboard imaging, or LungVision's AI-driven imaging.
