Abstract
BACKGROUND: In severe obesity, impairments in health-related quality of life (HRQoL) and dysphoric mood are reported. This is a post-surgery analysis of the relationship between HRQoL and depressive symptoms, and weight change after four different types of bariatric procedures. METHODS: A total of 105 consented patients completed the Short-Form-36 Health Survey (SF-36), the Impact of Weight on Quality of Life-Lite (IWQOL-Lite) and the Beck Depression Inventory (BDI) before and 25 months after surgery. Analysis of variance or Kruskal-Wallis test evaluated changes. RESULTS: Patients with Roux-en Y gastric bypass (46 patients), decreased body mass indexes (BMIs; kg m(-)(2)) 47-31 kg m(-)(2) (P<0.0001); biliopancreatic diversion with duodenal switch (18 patients), decreased BMIs 57-30 kg m(-)(2) (P<0.0001); adjustable gastric banding (18 patients), decreased BMIs 45-38 kg m(-)(2) (P<0.0001); and sleeve gastrectomies (23 patients), decreased BMIs 58 42 kg m(-)(2) (P<0.0001). The excess percentage BMI loss was 69, 89, 36 and 53 kg m(-)(2), respectively (P<0.0001). Before surgery, the SF-36 differences were significant regarding bodily pain (P=0.008) and social functioning (P=0.01). After surgery, physical function (P=0.03), general health (P=0.05) and physical component (P=0.03) were different. IWQOL-Lite recorded no differences until after surgery: physical function (P=0.003), sexual life (P=0.04) and public distress (P=0.003). BDI scores were not different for the four groups at baseline. All improved with surgery, 10.6-4.4 (P=0.0001). CONCLUSIONS: HRQoL and depressive symptoms significantly improvement after surgery. These improvements do not have a differential effect over the wide range of weight change.Nutrition & Diabetes (2014) 4, e132; doi:10.1038/nutd.2014.29; published online 1 September 2014.

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 it
