Abstract

fetched live from OpenAlex

The elderly represent a very rapidly increasing segment of human society worldwide. As people age, they accumulate multiple and chronic diseases that are very often managed with drug therapy. This approach to health maintenance is reflected by the fact that the elderly use a disproportionate amount of prescribed and over-the-counter medications compared to their numbers in the population. Cardiovascular diseases, almost always managed at least in part with drug therapy, remain a leading cause of morbidity and mortality in older individuals. Although we appreciate that there are physiological changes with aging to body composition, and renal, gastrointestinal, hepatic, and cardiovascular function that potentially confound optimization of drug therapy in the elderly, we have been slow to use this knowledge to improve pharmacological therapy of geriatric patients. This overview examines the physiological changes that commonly occur as we age, and focuses on the application of this knowledge to the potential for optimization of drug therapy of cardiovascular diseases of the elderly. Representative cardiovascular drugs are presented that are commonly used, and for which there is evidence of an opportunity to alter their use and potentially to improve therapy in this cohort.

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.
