Hypothyroidism following Hemithyroidectomy
Bibliographic record
Abstract
Objectives: Assess the rate of hypothyroidism following hemithyroidectomy. Methods: A retrospective study in adult patients undergoing hemithyroidectomy at the McGill University Thyroid Cancer Centre, during the years 2007 through 2012. Patients with preoperative hypothyroidism were excluded. Patients were followed 12 to 60 months after the primary surgery, and preoperative thyroid stimulating hormone (TSH) and free T4 levels were compared before and after the surgery. Hypothyroidism was defined as TSH levels >4.5 mU/L. Results: Of the 181 eligible patients in this study, 137 (75%) were females, with a mean age of 49.1 ± 14.3 years. The most common indication for surgery was follicular lesion. Hypothyroidism occurred in 65 (35%) of the patients, and was diagnosed at 1 to 36 months after surgery. Age and sex were not found to be risk factors for post‐hemithyroidectomy hypothyroidism. Conclusions: In this study 35% of patients undergoing hemithyroidectomy develop postoperative hypothyroidism. Upon preoperative patient counseling, hypothyroidism is a major morbidity that should be thoroughly discussed.

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.
