One of the world's leading causes of irreversible vision loss could begin with elevated eye pressure, according to a recent study published in the American Academy of Ophthalmology.

MIT researchers found that vision-language models, widely used to analyze medical images, do not understand negation words like “no” and “not.” This could cause them to fail unexpectedly when asked to retrieve medical images that contain certain objects but not others.

Researchers at the National Institutes of Health (NIH) have identified a series of changes in the architecture and cell composition of connective tissues of the breast, known as stromal tissue, that is associated with an increased risk of developing aggressive breast cancer among women with benign breast disease, and poorer rates of survival among women with invasive breast cancer. This process, which they call stromal disruption, could potentially be used as a biomarker to identify women with benign breast disease who are at high risk of developing aggressive breast cancers, as well as those with breast cancer who may be at increased risk of recurrence or death.

About The Study: In patients with overweight/obesity and/or diabetes, glucagon-like peptide 1 receptor agonist (GLP1-RA) treatment is not associated with increased risk of psychiatric adverse events or worsening depressive symptoms relative to placebo and is associated with improvements in quality of life, restrained eating, and emotional eating behavior. These findings provide reassurance regarding the psychiatric safety profile of GLP1-RAs and suggest that GLP1-RA treatment contributes to both physical and emotional well-being.

About The Study: In this cross-sectional study of cannabis use in veterans ages 65 to 84, use was common, and more than one-third who used in the past 30 days had any cannabis use disorder. The prevalence of past 30-day cannabis use was close to tobacco use prevalence, and risk factors for cannabis use were similar to those observed in other populations. Frequent and inhaled cannabis use was associated with higher odds of any cannabis use disorder. Routine health screening for cannabis use in Veterans Health Administration clinical settings is necessary to identify older adults with cannabis use.
