Abstract

fetched live from OpenAlex

Dementia is a leading contributor to burden of disease in Canada and the world.With an aging population, there are projected increases in its global prevalence.Evidence suggests that some neurodegenerative disorders, such as Alzheimer's disease, that lead to dementia are partly preventable, and that dietary intake of flavonoids may have relevant neuroprotective effects.The purpose of this study was to evaluate such potential for flavonoids using biochemical-and population-based analyses.Among 23 developed nations, negative correlations were found between rates of dementia and intake of all flavonoid groups, especially flavonols (p <0.05); these correlations were not significantly confounded by other relevant factors.The biochemical component helped elucidate possible mechanisms of flavonoid protection against heme-amyloidl3-enhanced oxidative reactions with potential relevance to neurotoxicity.Overall, the evidence suggests that flavonoids, especially flavonols, and flavonoid-rich foods are part of a preventive dietary strategy, along with other health-promoting factors, towards decreasing rates of dementia.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
