Objective:
To determine whether work output was related to cognitive limitations while at work in occupationally active breast cancer survivors (BCS) employed in a rapidly developing economy.
Methods:
Measures of demographics, job type, job stress, general distress (anxiety, depression), fatigue, work-related cognitive limitations, and work output were obtained using self-report measures in a cross-sectional study in both BCS and controls (n = 267/group).
Results:
Groups had similar educational backgrounds, job types, and levels of job stress. The BCS group was a median of 3.2 years post-primary treatment, slightly older, more likely to be divorced, have children, and was more likely working part-time. The BCS group reported higher levels of fatigue, general distress, and lower levels of work output (p < .05). A multivariate regression adjusting for group differences indicated that cognitive symptoms at work were related to lower levels of quantity, quality, and timeliness of completed work in the BCS group (adj. R2 = .57, unstandardized coefficient = 1.062, 95% CI = .436 to 1.689).
Conclusion:
When reported in the context of work, cognitive limitations were associated with lower levels of reported work output exclusively in the BCS group.
Implications For Cancer Survivors:
This study provides further evidence that cognitive limitations reported in the context of work in a developing country is similar to that of BCS working in more developed economies and is specific to BCS and not healthy workers with similar job types and job stress. Solutions to this problem may be applicable across countries.

Cardiac Output II: Effect of Stroke Volume on Cardiac Output
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...
Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
