This paper summarises two studies, in which measurement and calculation methods to determine the exposure of the general public around GSM and UMTS base stations have been developed and applied to different scenarios. The electromagnetic field variations around the stations in space and time are accounted for by appropriate maximisation techniques. Measurements show a bandwidth of exposures from 0.01% to more than 10% of field strength exposure limits. The distance to the station is not a main influencing factor, whereas the orientation to the main lobe and the sight conditions greatly influence exposure. Several commercially available numerical simulation tools were tested for their applicability on exposure forecast. In line-of-sight scenarios, all programs are able to predict the exposure accurately, whereas in non-line-of-sight situations, free space models overestimate the real exposure by some orders of magnitude.

Co-isolation of human donor eye cells and development of oncogene-mutated melanocytes to study uveal melanoma.
BMC Biol
January 2025
Cancer Research Program, Research Institute of the McGill University Health Centre, Montreal, QC, Canada.
Background: Uveal melanoma (UM) is the most common intraocular tumor in adults, arises either de novo from normal choroidal melanocytes (NCMs) or from pre-existing nevi that stem from NCMs and are thought to harbor UM-initiating mutations, most commonly in GNAQ or GNA11. However, there are no commercially available NCM cell lines, nor is there a detailed protocol for developing an oncogene-mutated CM line (MutCM) to study UM development. This study aimed to establish and characterize premalignant CM models from human donor eyes to recapitulate the cell populations at the origin of UM.

Trials
January 2025
Oxford Clinical Trials Research Unit, University of Oxford, Oxford, UK.
Background: Animated short videos used to explain a concept or project are often called animated explainer videos (AEVs). AEVs can supplement or provide an alternative to participant information sheets as a means of giving information about clinical research to potential participants. Current use of AEVs tends to focus on the specifics of a particular trial, yet there are many common aspects of clinical research regardless of the interventions being investigated that can be poorly covered in current trial materials.

BMC Med
January 2025
Med-X Center for Informatics, Sichuan University, Chengdu, China.
Background: Adverse life experiences have been associated with increased susceptibilities to psychopathology in later life. However, their impact on psychological responses following physical trauma remains largely unexplored.
Methods: Based on the China Severe Trauma Cohort, we conducted a cohort study of 2937 patients who were admitted to the Trauma Medical Center of West China Hospital between June 2020 and August 2023.
Evaluating agreement between individual nutrition randomised controlled trials and cohort studies - a meta-epidemiological study.
BMC Med
January 2025
Institute for Evidence in Medicine, Medical Center - University of Freiburg, Faculty of Medicine, University of Freiburg, Freiburg, Germany.
Background: In nutrition research, randomised controlled trials (RCTs) and cohort studies provide complementary evidence. This meta-epidemiological study aims to evaluate the agreement of effect estimates from individual nutrition RCTs and cohort studies investigating a highly similar research question and to investigate determinants of disagreement.
Methods: MEDLINE, Epistemonikos, and the Cochrane Database of Systematic Reviews were searched from January 2010 to September 2021.
Psoriasis increases the risk of Sjögren's syndrome: evidence from a propensity score-matched cohort study and transcriptomic analysis.
BMC Med
January 2025
Department of Rheumatology and Immunology, Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, Shanghai, China.
Background: Despite the well-documented immune dysregulation in both psoriasis and Sjögren's syndrome (SS), the specific link between these two autoimmune diseases has not been extensively explored. The present study aims to investigate the impact of psoriasis on the risk of SS.
Methods: A retrospective cohort study using TriNetX data compared SS development in patients with psoriasis and controls using propensity score matching, Kaplan-Meier curves, and Cox models.
