Abstract
Appraisal of the impact of Bariatric surgery on health related quality of life and work productivity in morbidly obese patients Background: In the last decades, morbid obesity has emerged as an increasingly prevalent chronic metabolic disorder affecting populations located in both developed and emerging countries. Obesity is associated with increased morbidity, disability and premature mortality. Given the impact of obesity on health status and its related economic burden, it is reasonable to anticipate that weight loss in obese patients will be associated with health and economic benefits. Bariatric surgery has emerged as a treatment of choice for this patient population. Significant reductions in mean percent excess weight loss and BMI percent change are observed as a consequence of Bariatric surgery. Several studies have established that obese individuals experience significant impairments in quality of life as a result of their condition. Health related quality of life (HRQoL) represents a particularly important and relevant outcome when assessing the overall impact of chronic conditions such as obesity. The data published as of date reports a significant correlation between excess weight loss and improvement in weight specific and physical aspects of HRQoL. However, trends toward decreases in HRQoL associated with weight regain between the first and sixth year post surgery have also been reported. The evidence relating to change in HRQoL in obese patients following Bariatric surgery for weight loss is currently either of relatively low quality or mainly focussed on evaluating the short-term impact of the intervention on HRQoL. Often overlooked but equally important is the relationship between obesity and its outcome on work productivity. Ample evidence underlining the correlation between obesity, increased work limitation and productivity loss may be found in the literature. The need for further evaluation of HRQoL and productivity loss outcomes over longer time horizons, following Bariatric surgery, has actually been identified as key areas of focus in this field of research, given the chronic nature of the disease and its considerable economic burden. Long-term outcomes data related to HRQoL and productivity loss following Bariatric surgery remains scarce in the Canadian setting. Objective: To describe the impact of Bariatric surgery on HRQoL and work productivity in patients with morbid obesity. Methodology: A cross-sectional survey measuring health related quality of life and work productivity outcomes, using the SF-36, the EQ-5D and the WLQ, for morbidly obese patients sampled from a population of patients being treated at the McGill University Health Centre (MUHC). Results: We observed Improvements in HRQoL and WLQ outcomes over the follow-up time period following Bariatric surgery and that, for all outcome measures. Conclusion: Following Bariatric surgery, patients may experience less physical disability and mental health issues and the perception of their health related quality of life state was reported to be significantly better than before the surgery. Per our findings, the initial positive impact of Bariatric surgery on HRQoL appeared to be sustained over time. Increases in physical disability, work limitations and decreases in patients' perception of their health status may be consequential to increments in BMI units and years of follow-up since the surgical intervention. Our findings further corroborated trends towards decreases in the occurrence of chronic comorbidities following Bariatric surgery.

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.
