Estrogen status and the renin angiotensin aldosterone system
Bibliographic record
Abstract
The renin-angiotensin-aldosterone system (RAAS) is integrally involved in multiple cardiovascular physiological processes including arterial blood pressure (BP) regulation. Over activity of the RAAS has been implicated in the pathogenesis of a number of cardiovascular disease entities, including hypertension. Several lines of evidence suggest estrogen favorably modulates the RAAS. Conversely, estrogen deficiency due to menopause may contribute to over activity of the RAAS. Of importance, estrogen deficiency in women is not exclusive to the postmenopausal period. Functional hypothalamic amenorrhea is a reversible cause of premenopausal hypoestrogenemia. In contrast to postmenopausal women (PMW), premenopausal women with exercise-associated functional hypothalamic amenorrhea demonstrate decreased, not increased, resting BP compared with their estrogen-replete eumenorrheic counterpart. In this review we briefly examine the effects of estrogen status on the RAAS and present the hypothesis that the RAAS is altered in physically active women with functional hypothalamic amenorrhea.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
