Aerobic exercise and CogniTIVe functioning in women with breAsT cancEr (ACTIVATE): A randomized controlled trial
Bibliographic record
Abstract
Abstract Background As the prevalence of chemotherapy‐related cognitive impairment rises, investigation into treatment options is critical. The objectives of this study were to test the effects of an aerobic exercise intervention initiated during chemotherapy compared to usual care (wait list control condition) on (1) objectively measured cognitive function and self‐reported cognitive function, as well as on (2) the impact of cognitive impairment on quality of life (QOL) postintervention (commensurate with chemotherapy completion). Methods The Aerobic exercise and CogniTIVe functioning in women with breAsT cancEr (ACTIVATE) trial was a two‐arm, two‐center randomized controlled trial conducted in Ottawa and Vancouver (Canada). Fifty‐seven women (M age , 48.8 ± 10 years) diagnosed with stage I–III breast cancer and awaiting chemotherapy were randomized to aerobic exercise initiated with chemotherapy ( n EX = 28) or usual care during chemotherapy with aerobic exercise after chemotherapy completion ( n UC = 29). The intervention lasted 12–24 weeks and consisted of supervised aerobic training and at‐home exercise. The primary outcome was objective cognitive function measured via 13 neuropsychological tests (standardized to M ± SD, 0 ± 1); secondary outcomes of self‐reported cognitive function and its impact on QOL were assessed via questionnaires. Data collected pre‐ and postintervention (the primary end point) were analyzed. Results Although no significant differences between groups were found for objective cognitive function outcomes postintervention after accounting for multiple testing, four of six self‐reported cognitive function outcomes showed significant differences favoring the aerobic exercise group. Conclusions Among women initiating chemotherapy for breast cancer, aerobic exercise did not result in significant differences in objective cognitive function postintervention after chemotherapy completion; however, the results do support the use of this intervention for improving self‐reported cognitive function and its impact on QOL.

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.
