The influence of altered circadian rhythm on sleep quality and cognition among shift workers of KLE Hospital: A comparative study
Bibliographic record
Abstract
Objectives: In shift workers, the internal biological clock is disrupted, leading to a substantial deterioration in sleep quality and cognitive abilities. Also, critical thinking, analytical reasoning and making quick decisions for patient management which are of utmost importance become questionable. Aim: To assess the effect of nighttime sleep deprivation on sleep quality and assessment of cognition in nurses doing night shift by doing a comparative study with age and gender-matched day time working controls. Materials and Methods: Ethical clearance was obtained from the institution. The study population of trainee nurses doing night shifts at KLE hospital and age and gender-matched controls doing day duty were selected and enrolled for data collection by inclusion - exclusion criteria and sample size calculation. Pittsburgh Sleep Quality Index questionnaire was used to assess sleep quality over the past 1-month. Montreal cognitive assessment test was conducted to detect the presence of any cognitive impairment among populations assessing 7 components of cognition. Statistical analysis: Mean ±SD was used and ‘p value=0.005’ was considered statistically significant. Results: Mean global PSQI score was 6.68 for shift workers while 5.56 for controls. Mean score for Montreal test was 23.64 for nurses and 27.76 for controls. Conclusion: In shift workers, sleep quality was poor and a significant reduction in cognitive functions like execution and memory recall as compared to day time working control population. These findings are related to the irregularities in the circadian rhythm and the natural cycle of sleep and waking, which in turn deteriorates cognitive abilities.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
