Thyroid Replacement Therapy: The Hidden Challenges
Bibliographic record
Abstract
Hypothyroidism has a gradual onset and non-specific symptoms, which might be subtle, and which might therefore be ignored or misdiagnosed. Subclinical hypothyroidism is a well-established phenomenon where a patient does not have thyroid symptoms, but shows biochemical evidences of hypothyroidism. However, diagnosis and treatment of these patients may prevent development of overt hypothyroidism and cardiovascular symptoms. Replacement therapy with levothyroxine (T4) is the treatment of choice for hypothyroidism; levothyroxine is taken daily, provides stable plasma levels and is suitable for the majority of patients. Patients with certain forms of hypothyroidism - central hypothyroidism, thyroidectomy patients and patients with “low T3 syndrome” - may benefit from treatment with liothyronine (T3), which is more potent and has a shorter onset of action. The use of liothyronine in combination with levothyroxine is controversial, but there is evidence that some patients, particularly those with deiodinase 2 and thyroid hormone transporter expression polymorphisms, may benefit from combination therapy.

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.
