The study, published in the journal Environmental Health Perspectives, demonstrates a link between long-term exposure to DDT and changes in the sperm epigenome. These changes, particularly in genes vital for fertility, embryo development, neurodevelopment, and hormone regulation, correspond to increased rates of birth defects and diseases, including neurodevelopmental and metabolic disorders.

To help optimise clinical management, EULAR has drafted new recommendations for the use of imaging in diagnosis and management of CiA. A special taskforce – made up of rheumatologists, radiologists, methodologists, healthcare professionals, and patient research partners – collected evidence from four systematic literature reviews. The new work, published in the February issue of the Annals of the Rheumatic Diseases includes five overarching principles and 10 recommendations. The principles stress that CiA are can be characterised by intermittent, acute episodes of inflammation – but they can also follow a chronic disease course with or without flares. Imaging provides useful information on crystal deposition, inflammation, and structural damage. However, abnormalities on imaging may not be related to clinical symptoms, and patient information including medical history, laboratory results, and physical examination are always the most relevant to be taken into account.

A study conducted by Aston University researchers has demonstrated that the appearance of ageing skin looks noticeably different compared to younger skin, when examined under polarised laser light. The scientists believe that their new finding could pave the way for new, non-invasive light-based techniques to detect diseases, including cancer, in older individuals. This could significantly enhance early-stage treatment options for various skin conditions. Journal of Biomedical Optics 2024 May;29(5):052912.
