Analysis of the Cortisol Diurnal Rhythmicity and Cortisol Reactivity in Long-Term Breast Cancer Survivors
Bibliographic record
Abstract
SUMMARY Aims: In this paper, we examine the long-term consequences of a breast cancer diagnosis on hypothalamic–pituitary–adrenal axis functioning. Methods: This study provides a comprehensive analysis of the diurnal and reactive cortisol profiles of breast cancer survivors considered ‘disease-free’ compared with women with no history of breast cancer. Results: The results indicate similar diurnal patterns in both groups; however, significant differences in stress reactivity were noted, with breast cancer survivors displaying a relatively flat profile following the acute stress induction. Subjective levels of psychological stress were similar in both groups, suggesting incongruence between perceived stress and the physiological stress response of breast cancer survivors. Conclusion: The patterns suggest a progression towards more typical cortisol reactivity with longer time since diagnosis and may reflect some recovery of hypothalamic–pituitary–adrenal axis functioning as time passes.

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.
