Older adults’ acceptability and perceived barriers to digital health tools integrating nutrition and physical activity: a focus group study

IntroductionThe rapid ageing of the population presents significant public health challenges, particularly in countries with high life expectancy such as Italy. Although nutrition and physical activity are key determinants of healthy ageing, many older adults do not meet recommended guidelines. Mobile health (mHealth) technologies may support healthy behaviors; however, evidence on older adults’ perspectives remains […]

Locally-deployed vs. cloud-based AI in healthcare: evaluating DeepSeek-R1:8b, DeepSeek-R1, and ChatGPT o3-mini-high for complex medical diagnostics

Reasoning large language models are increasingly considered for healthcare-related artificial intelligence applications, but their practical value depends not only on diagnostic accuracy, but also on responsiveness and operational reliability. In this study, we benchmarked six model settings on 1,000 questions from the MedQA dataset: DeepSeek-R1, its distilled 8-billion-parameter local variant DeepSeek-R1:8b, ChatGPT o3-mini-high, and their […]
