Foundation vision-language models are currently transforming computer vision, and are on the rise in medical imaging fueled by their very promising generalization capabilities. However, the initial attempts to transfer this new paradigm to medical imaging have shown less impressive performances than those observed in other domains, due to the significant domain shift and the complex, expert domain knowledge inherent to medical-imaging tasks. Motivated by the need for domain-expert foundation models, we present FLAIR, a pre-trained vision-language model for universal retinal fundus image understanding.

- The Genome Tunisia Project is a two-phase initiative (2022-2035) aimed at sequencing the Tunisian Genome and advancing personalized medicine in Tunisia, a diverse North African country affected by human migration patterns from various continents.
- A multidisciplinary team of Tunisian experts is focused on addressing key priorities, such as determining the reference genome sequence, enhancing education and awareness, and improving infrastructure for personalized medicine integration.
- The project involves collaboration among various stakeholders, including healthcare providers and policymakers, and aims to boost research and innovation in genomics while improving healthcare practices in the region.
Article Synopsis
- The study highlights the growing need for effective strategies to combat age-related cognitive decline among the aging population, specifically targeting older adults with mild cognitive impairment (MCI).
- It compares the effects of three interventions: aerobic exercise alone, aerobic plus cognitive exercises, and reading tasks, on cognitive functions like attention, memory, and problem solving.
- Results show that combining physical and cognitive exercises significantly enhances cognitive performance, particularly in working memory, compared to reading, while traditional aerobic exercise alone does not exhibit the same benefits.
Background: The evidence supporting the effectiveness of combined interventions in Alzheimer's disease (AD) patients remains inconclusive.
Objective: The aim of this study was to evaluate the mid- and long-term effectiveness of physical training, alone or combined with cognitive games, on cognitive performance in patients with moderate AD.
Methods: Seventy-nine AD patients (≈73% females, age of ≈70±1 years) were randomly divided into three groups: aerobic-based training (AT-group, = 27), aerobic-based training plus cognitive games (ACT-group, = 25), and a control group engaged in reading (CG, = 26), two sessions per week.
Introduction: The present study aimed to evaluate the effect of acute aerobic exercise on certain cognitive functions known to be affected by Alzheimer's disease (AD), with a particular emphasis on sex differences.
Methods: A total of 53 patients, with a mean age of 70.54 ± 0.
