This study assessed the diagnostic accuracy and fairness of multimodal large language models (ChatGPT-4 and LLaVA) in identifying skin diseases across various demographic groups. Analysis of approximately 10,000 medical images showed that while these AI models generally outperform traditional approaches, biases in performance related to sex and age were evident, particularly with LLaVA showing clear sex-related disparities.
Researchers advocate for attention to demographic fairness in AI-driven healthcare solutions. Further studies are planned to include additional demographic factors such as skin tone, aiming to enhance AI usability and reliability across diverse patient populations.
Until today, skin, brain, and all tissues of the human body were difficult to observe in detail with an optical microscope, since the contrast in the image was hindered by the high density of their structures. The research group of the Molecular Microscopy and Spectroscopy Lab at the Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology) in Genoa has devised a new method that allows scientists to see and photograph biological samples in all their complexity, obtaining clear and detailed images. The new technique has been made available to the scientific community in “open science” mode, representing an advantage in the biomedical field, since it allows us to observe active cells, even in the presence of diseases, as well as to understand how drugs interact with living tissues.
A research team developed a novel method using bidirectional reflectance factor (BRF) spectra combined with the PROSPECT-PRO model and modified ratio indices to estimate nitrogen content nondestructively.
A research team has developed a novel AI model, ILCD, and a supporting dataset, CDwPK-VQA, to help early diagnose crop diseases.
