Hiperplasia adrenal macronodular independente de ACTH (AIMAH): aspectos clínicos e moleculares
Bibliographic record
Abstract
AIMAH is a clinical condition characterized by the presence of adrenal macronodules even in the absence of ACTH. Usually the clinical overt syndrome only becomes apparent after several decades of life; this is probably due to the low steroidogenic enzyme capacity of the hyperplastic tissue. However, in asymptomatic individuals in whom the AIMAH was incidentally discovered, the HHA axis is usually disrupted. In the great majority of AIMAH cases, cortisol secretion is aberrantly regulated by hormones such as GIP, AVP, beta-adrenergic agonists, LH/hCG and in some cases by serotonin, acting through their specific receptors. The molecular mechanisms responsible by ectopic expression of such hormone receptors and/or their aberrant coupling to steroidogenesis are still largely unknown. Although this aberrant expression may have an important role in the augmented cell proliferation initiation, as well as in the steroidogenesis, it is probable that additional genetic events involving cell cycle regulation, adhesion and transcription occur. In rare cases GNAS1 mutations not related to McCune-Albright syndrome may be found in this condition. In some patients, the presence of aberrant hormone receptors creates the possibility of specific pharmacological treatment, isolated or associated with unilateral adrenalectomy.

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.
